The recent COVID-19 pandemic created an unpredictable environment regarding the safety operations of sport and recreation organizations. This study was designed to examine how safety climate and organizational innovativeness could promote preferred organizational behavior outcomes in college campus sport and recreation centers. A total of 227 sport and recreation employees were recruited through the National Intramural and Recreational Sports Association. With the collected data, we employed structural equation modeling to assess the research hypotheses. The results indicated that safety climate and innovativeness positively influenced job engagement, therefore leading to enhanced safety compliance and employee innovativeness, which ultimately resulted in higher levels of organizational performance. Peer safety compliance was also found to be a moderator in the relationship between job engagement and safety compliance. In this study, the authors offer new insights into sport organizational performance by emphasizing safety and innovation. [ABSTRACT FROM AUTHOR]

Construction workers face a high risk of various occupational accidents, many of which can result in fatalities. This study aims to develop a prediction model for nine prevalent types of construction accidents, utilizing construction tasks, activities, and tools/materials as input features, through the application of machine learning-based multi-class classification algorithms. 152,867 construction accident summary reports, composed of both structured (construction task, construction activity, accident type) and unstructured data (tools/materials) were used for the study. The study employed several data processing techniques, including keyword extraction through text mining, Boruta feature selection, and SMOTE data resampling enhance model accuracy. Three performance metrics (Multi-class area under the receiver operating characteristic curve (MAUC), Multi-class Matthews Correlation Coefficient (MMCC), Geometric-mean (G-mean)) were used to compare the predictive performance of four machine learning algorithms, including Decision tree, Random forest, Naïve bayes, and XGBoost. Of the four algorithms, XGBoost showed the highest performance in predicting accident type (MAUC: 0.8603, MMCC: 0.3523, G-mean: 0.5009). Furthermore, a Shapley additive explanation (SHAP) analysis was conducted to visualize feature importance. The findings of this study make a valuable contribution to improving construction safety by presenting a prediction model for accident types derived from real-world big data. [ABSTRACT FROM AUTHOR]

Workplace-related factors are associated with the risk of depression. Despite implementation of workplace health promotion (WHP) programmes in China to promote the physical and mental well-being of workers, the relationship between WHP and depression has received limited attention. This study investigated the association between WHP service utilisation and depressive symptoms among workers. This was a cross-sectional survey. A researcher-designed questionnaire was used to collect information on socio-demographic and occupational characteristics, WHP service utilisation, and mental health status. The Lasso method was used for variable selection to achieve dimension reduction, and logistic regression was used to assess the association between WHP service utilisation and depressive symptoms. The analysis included 11,710 workers, of whom 17.0% had depressive symptoms. Lasso regression resulted in 6 of 18 WHP services showing significant negative associations with depressive symptoms, including occupational safety training, mental health services, health check-ups, sports activities, fitness rooms, and healthy canteens. The logistic regression results showed that, after adjusting for sociodemographic and occupational factors, utilisation of these six services was associated with a decreased likelihood of depressive symptoms. The adjusted odds ratio (aOR) was 0.84 (95% confidence interval [CI]: 0.73–0.96) for occupational safety training, aOR: 0.82 (95% CI: 0.68–0.99) for mental health services, aOR: 0.80 (95% CI: 0.71–0.90) for health check-ups, aOR: 0.68 (95% CI: 0.57–0.80) for sports activities, aOR: 0.59 (95% CI: 0.47–0.74) for fitness rooms and aOR: 0.72 (95% CI: 0.59–0.87) for healthy canteens. Utilisation of WHP services was associated with a lower prevalence of depressive symptoms. Implementation of WHP services and the provision of a supportive workplace environment should be prioritised to benefit the mental health of workers. [ABSTRACT FROM AUTHOR]

Context: The Covid‐19 pandemic has added a new chapter to discussions about the professional duty to care. To understand how Covid‐19 may have changed medical students' ethical attitudes towards this duty, we analysed policies written before and during the pandemic by first‐year students completing a yearly educational exercise focused on work requirement expectations for healthcare professionals during a hypothetical epidemic. Methods: Within a repeated cross‐sectional design, consensus coding was performed on policies written over 5 years (2017–2021) using a codebook based on eight questions from the educational exercise for summative content analysis. Frequencies provided summative results and comparisons across years used Fisher's exact test. Results: We analysed 142 written policies from 2017 to 2021 representing 884 first‐year students working in small groups. Students' commitment to the duty to care remained stable during the Covid‐19 pandemic, but during the pandemic, students were more likely to support exceptions to the duty to care (e.g. for healthcare professionals with medical conditions or concern for household members' health) and more likely to expect institutions to provide safe working conditions. Ethical values supporting students' policies were largely consistent before and during the pandemic, the most common being beneficence, justice, duty to care, non‐maleficence and utility. Conclusions: Our results suggest that students' support for the duty to care remained strong during the Covid‐19 pandemic. We also found that students supported exceptions to this duty to reflect the needs of healthcare professionals and their families and that they expected institutions to provide safe working conditions. These findings can help inform ethics education and future pandemic preparedness. While students' support for the duty to care remained strong during the Covid‐19 pandemic, Kaldjian et al. explain their need for safe working conditions and concerns about the health of clinicians and their families."

It is well known that informal workers in developing countries are exposed to occupational health problems (OHPs), and they work unsafely. However, little is known about how their religious beliefs influence their safety behavior at the workplace. This study explores the interaction between the automobile artisans' religious beliefs and their workplace safety behavior. Forty three male artisans (either Christian: n = 17; or Muslim: n = 26) were purposively interviewed. Even though their religious teachings are against risk-taking, the artisans took risks at their workplace. Specific programs like seminars and various outreaches for workers in religious settings influence their perception of OHP prevention. Religious organizations have a role to play in OHP prevention.

Podologists are exposed to many occupational hazards, including volatile organic compounds (VOCs) from insole manufacturing and noise/vibration during nail or tissue grinding. In this study, VOCs, noise, and vibration were measured in five podiatry clinics and three offices. Questionnaires were administered to 23 podologists and 19 office workers to inquire about their pain, ocular, skin and respiratory complaints. The results showed that the podologists' exposure to the total VOC concentrations was approximately twice as high as that of the office workers. The podologists' complaints regarding pain were found to be correlated with ambient noise and hand-arm vibration levels. Ocular, skin, and respiratory complaints were also found to be correlated with total VOC concentrations. These results suggest that VOCs, noise and vibration in the working environment may impair podologists' health and that they have an intensifying effect on each other, increasing the severity of health issues.

Leader affective presence, the tendency of leaders to consistently evoke feelings in team members, has gained prominence in the context of leadership and teamwork. However, prior research lacks a comprehensive theoretical framework, focuses on limited team processes, and relies mainly on cross sectional designs to study this construct. Building upon theories of the social functions of affect, this study examines the relationship between leaders' affective presence and team member behaviour, specifically focusing on team proactive problem prevention and examining whether this relationship is mediated by team psychological safety. Using a two‐wave panel model with 504 professionals in 134 teams, our findings revealed that positive leader affective presence, characterized by instilling enthusiasm, joy and inspiration among team members, was positively associated with perceptions of team psychological safety. In turn, team psychological safety was positively related to leaders' assessments of proactive problem prevention. Interestingly, negative leader affective presence, which triggers worry, tension and stress, was not related to team psychological safety but was positively associated with team proactive problem prevention. These results highlight the importance of leader affective presence in shaping emergent team states and team member behaviour. Researchers and practitioners should thus consider these insights when assessing and intervening in leadership and teamwork processes in organizations. [ABSTRACT FROM AUTHOR]

Purpose: To assess pharmacists' mental well-being, perceptions of safety, and willingness to administer vaccines before and during the COVID-19 pandemic. Methods: An electronic survey was administered to a convenient sample of practicing pharmacists working in Alabama, Tennessee and Texas. The 33-item survey examined pharmacists' beliefs about the pandemic's impact on their mental well-being, their perceptions of safety in vaccine administration, and their willingness to vaccinate. Responses were assessed on a 5-point Likert scale, ranging from strongly disagree (1) to strongly agree (5). A recruitment email with the survey link was sent to pharmacists, with periodic reminders over a 4-week period. Descriptive statistics and bivariate analyses were utilized to evaluate survey responses. Results: A total of 387 responses were analyzed, with an estimated response rate of 3.93%. Most respondents were women (65%) and had at least 6 to 10 years of practice experience (28%). Overall, participants felt that the pandemic worsened their mental well-being, with women reporting a more negative mental well-being compared with men (P <.001). They reported having less time during workflow to apply personal protective equipment (PPE) (P =.0074) compared to before the pandemic. They also reported a decrease in willingness to vaccinate adult patients during the pandemic (P <.0001), and that concern about contracting COVID-19 prevented them from giving vaccinations (P <.0001). Conclusions: Pharmacists felt their mental well-being and willingness to vaccinate patients suffered as a result of the COVID-19 pandemic. Future research and initiatives that focus on improving vaccination rates should also consider pharmacists' concerns and well-being. [ABSTRACT FROM AUTHOR]

Construction operations, particularly concrete formwork, pose significant risks of musculoskeletal disorders (MSDs) to workers. Previous studies have examined the MSDs associated with conventional job-built formwork. In light of the growing popularity of modern ready-made formwork systems, and the claim that such systems reduce MSDs, it is imperative that researchers characterize the activities associated with the use of these systems and offer empirical insight into their relationship with MSDs. In response to this need, this study aims to assess and compare MSD risks related to different modern formwork systems. Specifically, the Rapid Entire Body Assessment (REBA), a method for full-body postural ergonomic risk assessment, was used to study the ergonomic hazards of form workers during the installation and removal of horizontal modular and prefabricated or engineered formwork systems. The findings indicate that most formwork tasks and activities subject workers to medium to high MSD risks, necessitating preventive actions or imminent preventive actions. Modular formwork systems may subject workers to fewer hazardous ergonomic working conditions compared with prefabricated or engineered formwork systems. The findings provide an improved understanding of formwork activities and the MSD risks associated with ready-made formwork system construction, and provide a valuable resource for formwork designers and constructors dedicated to improving worker health and safety in formwork construction.

Existing approaches to infrastructure management neglect the impact of infrastructure condition on safety performance, even though poorly maintained roadways can contribute to increased crash frequencies. This is perhaps because very few studies have quantified the impact of infrastructure condition on safety performance. Hence, this work develops safety performance function (SPF) models that relate pavement condition—specifically, roughness, as measured using the international roughness index (IRI)—and other roadway factors with observed crash frequencies. These SPFs are then combined with pavement roughness deterioration models to better understand how maintenance decisions can be used to improve roadway safety performance. Data from two-lane rural roadways in Pennsylvania are used for this effort. The SPF estimation results reveal that accounting for IRI in SPF development significantly improves model fit, and that IRI has a significant and positive impact on crash outcomes. The results further suggest that the IRI has a different impact on total crash frequency as compared to fatal and injury crash frequency, and rear-end crashes. This is likely due to how roughness of the roadway can impact travel speeds. Finally, the results also show that maintenance activities that reduce IRI can have significant safety benefits. This suggests that pavement management decisions should also consider the anticipated safety benefits, in addition to other factors. [ABSTRACT FROM AUTHOR]

Background: Efforts to increase capacity for oncology treatment in the author's Chemotherapy Day Unit, while allowing staff to treat more patients and offer more flexibility to patients, increased strain on the Aseptic Pharmacy at the author's Trust. Therefore, the possibility of nurse-led drug preparation was explored. Aims: Nurse-led monoclonal antibody (MAb) preparation was piloted to investigate whether a reduction in reliance on Aseptic Pharmacy could co-exist with maintaining optimal treatment capacity. The effectiveness of a closed system transfer device (CSTD) to protect nurses against drug exposure was also explored. Methods: A risk assessment for MAbs considered for nurse-led preparation was created, alongside a procedure for the safe handling of systemic anti-cancer therapy (SACT) with the use of a CSTD. Findings: The pilot resulted in an 89% reduction in the time patients had to wait for MAbs to be prepared. Seven oncology drugs were included in the new procedure without increasing the risk of exposure for nurses. Conclusion: The pilot successfully reduced demand on Aseptic Pharmacy while enabling efficient capacity use on the Chemotherapy Day Unit. The use of the CSTD minimised the risk of nurse exposure to SACT. [ABSTRACT FROM AUTHOR]

Internationally, community healthcare is provided by personal health budgets or personalised schemes as part of a consumer-directed care emphasis. Although the introduction of a personalised scheme in Australia has improved the lives of many, people with psychosocial disability (PSD) and their families have experienced many challenges with service integration. Six focus groups with 17 National Disability Insurance Scheme (NDIS) support workers were conducted between June and November 2022. Participants were asked semistructured questions about their engagement with emergency department (ED) clinicians when presenting with a person with PSD and NDIS plan. They were also asked how they contribute to service integration to improve communication practices between the two services. A qualitative, descriptive thematic analysis approach was used. Results indicate there is a need for improved service integration pathways between the ED and NDIS services. The thematic analyses identified five main themes: the ED is harmful and not safe, but nowhere else to go; make the ED safe; further training for ED staff; improving communication across services; and alternatives to the ED. This study reports NDIS support worker's experience when supporting a person they are caring for in the ED. NDIS support workers have an understanding of the needs of the people they care for;their wisdom can contribute greatly to ED clinical responses in crisis care. Recommendations are offered to assist with service integration between the two systems. [ABSTRACT FROM AUTHOR]

In response to the need for a space security situation assessment during orbit, the multi-satellite space environmental risk prediction and early warning system is based on the detection results of the space weather payload of the Fengyun 4A and 4B satellites, as well as the prediction results of the National Space Weather Center, for the first time. By comprehensively utilizing some open-source data, it is the first time that we have achieved a 24 h advanced prediction of the space environment high-energy proton, low-energy particle, and high-energy electron risks for the safety of the Fengyun-series high-orbit satellites, and a real-time warning of satellite single-event upset, surface charging, and deep charging risks. The automation system has preliminarily achieved an intelligent space risk assessment for the safety of multiple stationary meteorological satellites, effectively improving the application efficiency of the space environmental data and the products of Fengyun-series satellites. The business status is stable in operation, and the resulting error between the predicted results of various risk indices and the measured data was less than one level. The warning accuracy was better than 90%. This article uses the system for the first time, to use Fengyun satellite data to, accurately and in a timely manner, predict and warn us about the low-energy particles and surface charging high-risk levels of the Fengyun 4A and 4B satellites during the typical space weather event on 21 April 2023, in response to the impact of complex spatial environmental factors on the safety of Fengyun-series high-orbit satellites. The construction and operation of a multi-satellite space environmental risk prediction and early warning system can provide a reference for the safety work of subsequent satellite ground system operations.

Background: Due to climate change, the increasing frequency of hot summer days and heat waves can result in occupational heat strain, especially in non-air-conditioned workplaces. Healthcare workers (HCW) engaged in patient care are particularly affected, as they are additionally exposed to physical stress. The use of personal protective equipment (PPE) can aggravate heat strain in HCW. This study aimed to examine the subjective well-being of HCW when exposed to heat and PPE under controlled conditions. Methods: This study was designed as a randomized crossover trial. Participants performed standardized healthcare tasks in a climatic chamber for approximately 3.5 h at different indoor temperatures (22 °C and 27 °C) and varied working conditions (with or without PPE). The effects on participants' subjective well-being, encompassing thermal, physiological and psychological stress were assessed using a customized questionnaire. Results: Heat had a greater effect than PPE on thermal, physical and psychological stress. Conversely, PPE had a greater effect on physical demand and effort. For the majority of outcomes, combined exposure to heat and PPE resulted in the highest perceived discomfort. Furthermore, the participants reported increased sweating and other discomforts when working at elevated temperatures or with PPE. Conclusions: In this study, heat and PPE, but particularly the combination of both factors, were identified as unfavorable working environments. Although the trials were conducted in a controlled environment, the outcomes provide valuable information about the effect of heat and PPE on HCW in a real-life setting. Furthermore, the design used in this study can be beneficial in evaluating the effect of mitigation strategies. [ABSTRACT FROM AUTHOR]

[Display omitted] To meet the requirements in air quality monitors for the public and industrial safety, sensors are required that can selectively detect the concentration of gaseous pollutants down to the parts per million (ppm) and ppb (parts per billion) levels. Herein, we report a remarkable NH 3 sensor using Ni-doped CeO 2 octahedral nanostructure which efficiently detects NH 3 as low as 45 ppb at room temperature. The Ni-doped CeO 2 sensor exhibits the maximum response of 42 towards 225 ppm NH 3 , which is ten-fold higher than pure CeO 2. The improved sensing performance is caused by the enhancement of oxygen vacancy, bandgap narrowing, and redox property of CeO 2 caused by Ni doping. Density functional theory confirms that O vacancy with Ni at Ce site (V O Ni Ce) augments the sensing capabilities. The Bader charge analysis predicts the amount of charge transfer (0.04 e) between the Ni-CeO 2 surface and the NH 3 molecule. As well, the high negative adsorption energy (≈750 meV) and lowest distance (1.40 Å) of the NH 3 molecule from the sensor surface lowers the detection limit. The present work enlightens the fabrication of sensing elements through defect engineering for ultra-trace detection of NH 3 to be useful further in the field of sensor applications.

The river levee settlement derived from shield tunnel excavation face instability is an anticipated safety issue. Serious engineering safety hazards may occur if it is not restricted. Thus, this study selected six influence indicators to quantify the stability level of the excavation face using the AHP-Fuzzy method. A database of the levee settlement prediction indicators containing tunneling speed, supporting pressure, grouting pressure, horizontal distance, lagging distance, and stability coefficient of excavation face was built by collecting 60 samples from a river-crossing shield tunnel project in China. Five models were carried out for predicting the levee settlement, i.e., modified Peck formula, RF, SVM, BPNN, and PSO-BPNN. Their prediction performance was verified by comparing the prediction results with the measured ones in a shield tunnel engineering application. The analytical results indicated that the PSO-BPNN model has the highest correlation coefficient, i.e., 0.8831(in training) and 0.8657(in testing) and the lowest error, i.e., RMSE = 1.901, and MAE = 0.8412, respectively. Thus the PSO-BPNN model has the best ability to capture the nonlinear relationship between the independent and dependent variables compared with the abilities of the RF, SVM, and BPNN model in this case study. The modified Peck formula performed unsatisfactory results (RMSE = 3.2588, MAE = 3.1172). The correlation analysis results of the input characteristic parameters of the model also indicate that the stability of the levee settlement is significantly related to the excavation face stability. The results indicate that the hybrid model is a very useful and powerful means to investigate the levee settlement caused by shield tunneling and can be improved by gathering more data from tunneling operations over time.

Sexual and gender minorities (SGMs) are individuals with sexual orientations, gender identities, or expressions (or a combination of these) that differ from cultural norms. Sexual and gender minorities often face workplace discrimination and report decreased physical and emotional well-being from discrimination. To explore the workplace climate of SGM athletic trainers (ATs). Sequential mixed-methods study. Web-based survey and interviews. Criterion sampling of SGM ATs (117 survey participants and 12 interview participants). We modified the LGBTQ Inclusion Assessment and the Organizational Self-Assessment for the survey and developed a semistructured interview script (scale-level content validity index = 0.94). We used means ± SDs, frequencies (%), and the consensual qualitative research tradition to characterize participant responses. Trustworthiness was established through reflexivity (researchers checking bias throughout the research process), member-checking, multianalyst triangulation, and internal and external auditing. Participants indicated their workplace was inclusive (24 [20.5%]), somewhat inclusive (29 [24.8%]), or not inclusive (14 [12.0%]) or did not indicate at all (50 [42.7%]). Respondents most often noted they were unsure of which stage of change their organizations and organizational units were in addressing lesbian, gay, bisexual, transgender, queer, questioning, pansexual, intersex, asexual, 2-spirit, and all within the community of queer and transspectrum identities (LGBTQPIA+) concerns in the workplace as well as specific actions taken for inclusion. Two domains emerged from the interview data: safety and inclusion. The safety domain represented aspects of the workplace climate that made participants feel safe and includes organizational initiatives (12/12), patient-centered policies (7/12), local and federal regulations (7/12), and signaling (12/12). The inclusion domain represented how participants felt a sense of belonging to the organization through their own experience (12/12), through the experiences of their patients (9/12), and through an infrastructure designed for inclusion (12/12). Participants expressed both affirmative and negative feelings of safety and inclusion throughout their responses. Organizations must take both structural and cultural actions to address the concerns of exclusion and lack of safety. [ABSTRACT FROM AUTHOR]

BACKGROUND: Musculoskeletal discomfort is widely experienced by surgeons across multiple surgical specialties. Developing technologies and new minimally invasive techniques add further complexity and ergonomic stressors. These stressors differentially affect male and female surgeons, but little is known about the role these sex disparities play in surgical ergonomic stress. We reviewed existing literature to better understand how ergonomic stress varies between male and female surgeons. STUDY DESIGN: A literature search was performed via PubMed including but not limited to the following topics: ergonomics, surgeons, female surgeons, women surgeons, pregnancy, and operating room. A review of available quantitative data was performed. RESULTS: Female surgeons endure more pronounced ergonomic discomfort than their male counterparts, with added ergonomic stress associated with pregnancy. CONCLUSIONS: A 4-fold method is proposed to overcome ergonomic barriers, including (1) improved education on prevention and treatment of ergonomic injury for active surgeons and trainees, (2) increased departmental and institutional support for ergonomic solutions for surgeons, (3) partnerships with industry to study innovative ergonomic solutions, and (4) additional research on the nature of surgical ergonomic challenges and the differential effects of surgical ergonomics on female surgeons.

Objective: We sought to test whether a 2-week Total Worker Health (TWH) training mapped to TWH education competencies could be administered to a Mexican audience of occupational safety and health professionals and could lead to positive changes to knowledge and behaviors. Methods: This study used robust program evaluation methods collected before and after each of the nine training days and at the end of the course. Results: Overall course quality received a mean score of 4.6 (SD = 0.6) and 98.8% of participants agreed that their TWH knowledge increased. All participants intended to make at least one change to their professional practice, most frequently helping companies assess their organizational culture to support health, safety, and well-being. Conclusions: This TWH training was well received and led to positive self-reported increase in knowledge and abilities to influence workers' health, safety, and well-being. [ABSTRACT FROM AUTHOR]

Introduction: Investigations about the interrelationships of nurses' safety climate, quality of care, and standard precautions (SP) adherence and compliance remain particularly scarce in the literature. Thus, we tested a model of the associations between nurses' safety climate, quality of care, and the factors influencing adherence and compliance with SPs utilizing the structural equation modeling (SEM) approach. Design: Cross‐sectional design complying with STROBE guidelines. Methods: Using convenience sampling, nurses (n = 730) from the Philippines were recruited. Data were collected between April and September 2022 using four validated self‐report measures. Spearman Rho, mediation and path analyses, and SEM were employed for data analysis. Results: Acceptable model fit indices were shown by the emerging model. The safety climate is positively associated with quality of care and factors influencing adherence to and compliance with SPs. Quality of care directly affected factors influencing adherence to SPs. The factors influencing adherence to SPs directly affected SP compliance. Quality of care mediated between safety climate and the factors influencing adherence to SPs. Factors influencing adherence to SPs mediated between safety climate, quality of care, and SP compliance. Conclusions: The study's variables are not distinct but overlapping nursing concepts that must be examined collectively. Nurse administrators can utilize the emerging model to formulate strategies and regulations for evaluating and enhancing nurses' safety climate, quality of care, and SP adherence and compliance. Clinical Relevance: Our findings may impact policymaking, organizational, and individual levels to improve nurses' clinical practice. Patient or Public Contribution: This study had no patient contribution or public funding. [ABSTRACT FROM AUTHOR]

Background: Failure mode and effects analysis (FMEA), which is an effective tool for error prevention, has garnered considerable attention in radiotherapy. FMEA can be performed individually, by a group or committee, and online. Purpose: To meet the needs of FMEA for various purposes and improve its accessibility, we developed a simple, self‐contained, and versatile web‐based FMEA risk analysis worksheet. Methods: We developed an FMEA worksheet using Google products, such as Google Sheets, Google Forms, and Google Apps Script. The main sheet was created in Google Sheets and contained elements necessary for performing FMEA by a single person. Automated tasks were implemented using Apps Script to facilitate multiperson FMEA; these functions were built into buttons located on the main sheet. Results: The usability of the FMEA worksheet was tested in several situations. The worksheet was feasible for individual, multiperson, seminar, meeting, and online purposes. Simultaneous online editing, automated survey form creation, automatic analysis, and the ability to respond to the form from multiple devices, including mobile phones, were particularly useful for online and multiperson FMEA. Automation enabled through Google Apps Script reduced the FMEA workload. Conclusions: The FMEA worksheet is versatile and has a seamless workflow that promotes collaborative work for safety.

Over the past 15 years, there have been numerous fatalities related to working with animal slurry. Working with cattle slurry releases toxic gases, in particular, hydrogen sulphide (H2S), which can cause acute central nervous system toxicity, breathing difficulties, and death if exposed to high concentrations. Real-time measurements of H2S gas were taken over distance and time, during the stirring of cattle slurry on farms. Gas was measured at eight slurry stores with differing typical configurations of indoor or outdoor stores and with or without slatted flooring. Highest H2S gas levels were measured from indoor stores under slatted floors, and generally at positions closest to the stirrer or the point of maximum stirring, with levels decreasing with distance from source. Most of the data indicate H2S gas levels increase very rapidly after stirring starts, and mostly decline to baseline levels within 30 min post start of stirring. There were, however, circumstances where gas levels remained high and only started to decline once the stirrer had stopped. H2S gas levels at all farms, at all positions measured were consistently below 10 ppm within 30 min of the stirrer being stopped. The current data highlight areas of the farm and ways of working that have the potential for workers and others to be at risk of exposure to toxic slurry gases. The area should be left to ventilate naturally for at least 30 min after the stirrer has been stopped before re-entering buildings. Influencing the design of stirring equipment and future slurry stores would likely reduce the risk of worker exposure to slurry gases. [ABSTRACT FROM AUTHOR]

Background This study was conducted as an effort to develop a Korean construction job exposure matrix (KoConJEM) based on 60 occupations recently consolidated by the construction workers mutual aid association for use by the construction industry. Methods The probability, intensity, and prevalence of exposure to 26 hazardous agents for 60 consolidated occupations were evaluated as binary (Yes/No) or four categories (1 to 4) by 30 industrial hygiene experts. The score for risk was calculated by multiplying the exposure intensity by the prevalence of exposure. Fleiss' kappa for each hazardous agent and occupation was used to determine agreement among the 30 experts. The JEM was expressed on a heatmap and a web-based dashboard to facilitate comparison of factors affecting exposure according to each occupation and hazardous agent. Results Awkward posture, heat/cold, heavy lifting, and noise were hazardous agents regarded as exposure is probable by at least one or more experts in all occupations, while exposure to asphalt fumes was considered hazardous in the smallest number of occupations (n = 5). Based on the degree of agreement among experts, more than half of the harmful factors and most occupations showed fair to good results. The highest risk value was 16 for awkward posture for most occupations other than safety officer. Conclusions The KoConJEM provides information on the probability, intensity, and prevalence of exposure to harmful factors, including most occupations employing construction workers; therefore, it may be useful in the conduct of epidemiological studies on assessment of health risk for construction workers.

Graduates of industrial hygiene training (IH) programs must be able to meet continuously evolving health and safety needs in a wide variety of occupational settings. Therefore, academic IH graduate programs must regularly evaluate their curricula and solicit input from industry professionals to make curricular changes that will better prepare their students for professional roles in industry. The purpose of this study was to identify the training gaps that existed between industry needs and the current curriculum for a United States-accredited IH graduate training program. The research team facilitated two group interviews with the IH program advisory board, collected alumni survey data, and performed a qualitative analysis to identify skills gaps/needs for the IH Program graduates. The research team identified 3 themes from participant interviews and alumni surveys (technical, applied, and essential skills) and selected several skills within each theme that interview participants thought were necessary proficiencies for junior IH professionals. The skills identified in the qualitative interview and survey data can be incorporated into the curriculum to improve the training of IH graduate students. Additionally, by using qualitative analysis, the researchers uncovered essential skills previously unidentified in IH needs assessments, providing valuable information for all IH graduate programs.

Objectives The dermal exposure route is expected to become increasingly significant relative to total worker exposure as inhalational exposure limits continue to decrease. However, standardization of occupational exposure assessment methods and scientific consensus are needed. This is the first scoping review mapping the literature across all dermal exposure assessment methods and their targeted substances/chemicals in occupational settings. Methods Eligibility criteria broadly included studies reporting any noninvasive dermal exposure assessment method in an occupational setting. The literature search (Web of Science and MEDLINE) was restricted to peer-reviewed, primary literature published in the last 20 years (2002–2022). Titles/abstracts were dual independently screened. Data charting was performed by a single reviewer using standard template. All stages were pilot tested. The JBI (formerly, the Joanna Briggs Institute) scoping review methods and PRISMA-ScR checklist (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews) were used. Results In total, 493 articles were data charted and categorized by 4 study types: methods development (22%), exposure assessment (51%), health outcomes (21%), and controls assessment (6%). Fourteen types of dermal exposure assessment methods were charted with biomarkers (51%), dosimeters (21%), and qualitative assessments such as questionnaires or surveys (17%) most common. Seventeen different chemicals/substances were charted; pesticides (28%) and polycyclic aromatic hydrocarbons (PAHs) (22%) associated with crude oil products and combustion were most common. Mapping between substances and exposure assessment method categories, pesticide dosimeters (11%), and PAH biomarker studies (14%) were most reported. Literature gaps were identified for cleaning agents, hair dyes, glycol ether, N , N -dimethylformamide/ N -methyl-2-pyrrolidone, dioxins, and bisphenol A. Conclusions To foster scientific consensus, standardization across study reporting is needed for describing: (i) exposure assessment methods used, (ii) worker tasking/conditions, (iii) targeted substances and substance state, and (iv) targeted exposure routes. Overall, this review categorizes, maps, and defines the scope of literature for occupational dermal exposure assessment methods. [ABSTRACT FROM AUTHOR]

Personal air monitoring using a TSI SidePak AM520 personal aerosol monitor was performed on a northern Colorado construction site during five tasks from the OSHA Table 1 : Specified Exposure Control Methods When Working With Materials Containing Crystalline Silica to estimate silica dust concentrations in real time. Photometric measurements were modified using a gravimetric correction factor and a % respirable crystalline silica adjustment. Each task was sampled once; sample time ranged from 14 min to 40 min, with a mean sample time of 27 min. The mean silica dust concentration estimates (μg/m3) (standard deviation [SD]) for the five tasks computed from the TSI SidePak AM520 respirable dust measurements were core drilling 12 μg/m3 [2.46], grinding 918 μg/m3 [1134.08], cutting with a walk-behind saw 36 μg/m3 [79.67], jackhammering 27 μg/m3 [23.24], and dowel drilling 66 μg/m3 [77.65]. Silica exposure estimates from real-time monitoring can be used to identify exposures that may be related to inadequate controls or worker behaviors that contribute to peak exposures. Respirable crystalline silica exposure estimates presented here are likely not generalizable to other construction sites or tasks. [ABSTRACT FROM AUTHOR]

Determining the vapor pressure of a substance at the relevant process temperature is a key component in conducting an exposure assessment to ascertain worker exposure. However, vapor pressure data at various temperatures relevant to the work environment is not readily available for many chemicals. The Antoine equation is a mathematical expression that relates temperature and vapor pressure. The objective of this analysis was to compare Antoine parameter data from 3 independent data sources; Hansen, Yaws, and Custom data and identify the source that generates the most accurate vapor pressure values with the least bias, relative to the referent data set from the CRC Handbook of Chemistry and Physics. Temperatures predicted from 3 different Antoine sources across a range of vapor pressures for 59 chemicals are compared to the reference source. The results show that temperatures predicted using Antoine parameters from the 3 sources are not statistically significantly different, indicating that all 3 sources could be useful. However, the Yaws dataset will be used in the SDM 2.0 because the data is readily available and robust. [ABSTRACT FROM AUTHOR]

Structural firefighters are exposed to a complex set of contaminants and combustion byproducts, including volatile organic compounds (VOCs). Additionally, recent studies have found structural firefighters' skin may be exposed to multiple chemical compounds via permeation or penetration of chemical byproducts through or around personal protective equipment (PPE). This mannequin-based study evaluated the effectiveness of four different PPE conditions with varying contamination control measures (incorporating PPE interface design features and particulate blocking materials) to protect against ingress of several VOCs in a smoke exposure chamber. We also investigated the effectiveness of long-sleeve base layer clothing to provide additional protection against skin contamination. Outside gear air concentrations were measured from within the smoke exposure chamber at the breathing zone, abdomen, and thigh heights. Personal air concentrations were collected from mannequins under PPE at the same general heights and under the base layer at abdomen and thigh heights. Sampled contaminants included benzene, toluene, styrene, and naphthalene. Results suggest that VOCs can readily penetrate the ensembles. Workplace protection factors (WPFs) were near one for benzene and toluene and increased with increasing molecular weight of the contaminants. WPFs were generally lower under hoods and jackets compared to under pants. For all PPE conditions, the pants appeared to provide the greatest overall protection against ingress of VOCs, but this may be due in part to the lower air concentrations toward the floor (and cuffs of pants) relative to the thigh-height outside gear concentrations used in calculating the WPFs. Providing added interface control measures and adding particulate-blocking materials appeared to provide a protective benefit against less-volatile chemicals, like naphthalene and styrene.

N95 respirators are the core equipment used by healthcare workers to prevent the spread of respiratory diseases. The protective effect of N95 against infection spread depends on the fit of the N95 to the wearer, which is related to the wearer's facial dimensions. The purpose of this cross-sectional study was to assess the relationship between the fit of three types of N95 and facial dimensions. A total of 305 healthcare workers from ten hospitals in Beijing were recruited for this study. Facial dimensions of workers were measured using Intel RealSense Depth Camera D435. Fit testing was conducted on three types of N95 using the TSI-8038 Porta Count Pro + Respirator Fit Tester. Possible associations between the fit test results and facial dimension data were examined. A Porta Count reading of 100 was used as the criterion for an acceptable fit. The fit of the folding respirators was positively correlated with nose length (r = 0.13, p = 0.02), nose height (r = 0.14, p = 0.02), and face width (r = 0.12, p = 0.03), whereas that of flat respirators was correlated with nose width (r = 0.16, p < 0.01), chin length (r = 0.18, p < 0.01), and pro-face width (r = 0.13, p = 0.02), and that of arched respirators was correlated with the nose length (r = 0.13, p = 0.03). The fit of N95 for wearers depends on their facial features. The results of this study can provide advice for medical workers to choose the appropriate N95. Medical staff should fully consider their facial dimensions when choosing an appropriate N95 to improve the protective efficacy of respirators and to reduce the risk of infection by respiratory diseases.

Background: Strong cultures of workplace safety and patient safety are both critical for advancing safety in healthcare and eliminating harm to both the healthcare workforce and patients. However, there is currently minimal published empirical evidence about the relationship between the perceptions of providers and staff on workplace safety culture and patient safety culture. Methods: This study examined cross-sectional relationships between the core Surveys on Patient Safety Culture™ (SOPS®) Hospital Survey 2.0 patient safety culture measures and supplemental workplace safety culture measures. We used data from a pilot test in 2021 of the Workplace Safety Supplemental Item Set, which consisted of 6,684 respondents from 28 hospitals in 16 states. We performed multiple regressions to examine the relationships between the 11 patient safety culture measures and the 10 workplace safety culture measures. Results: Sixty-nine (69) of 110 associations were statistically significant (mean standardized β = 0.5; 0.58 < standardized β < 0.95). The largest number of associations for the workplace safety culture measures with the patient safety culture measures were: (1) overall support from hospital leaders to ensure workplace safety; (2) being able to report workplace safety problems without negative consequences; and, (3) overall rating on workplace safety. The two associations with the strongest magnitude were between the overall rating on workplace safety and hospital management support for patient safety (standardized β = 0.95) and hospital management support for workplace safety and hospital management support for patient safety (standardized β = 0.93). Conclusions: Study results provide evidence that workplace safety culture and patient safety culture are fundamentally linked and both are vital to a strong and healthy culture of safety.

Aim: To explore nurse‐midwives' perceptions of safety culture in maternity hospitals. Design: A descriptive phenomenological study was conducted using focus groups and reported following the Consolidated Criteria for Reporting Qualitative Research. Methods: Data were obtained through two online focus group sessions in June 2022 with 13 nurse‐midwives from two maternity hospitals in the central region of Portugal. The first focus group comprised 6 nurse‐midwives, and the second comprised 7 nurse‐midwives. Qualitative data were analysed using content analysis. Findings: Two main themes emerged from the data: (i) barriers to promoting a safety culture; (ii) safety culture promotion strategies. The first theme is supported by four categories: ineffective communication, unproductive management, instability in teams and the problem of errors in care delivery. The second theme is supported by two categories: managers' commitment to safety and the promotion of effective communication. Conclusion: The study results show that the safety culture in maternity hospitals is compromised by ineffective communication, team instability, insufficient allocation of nurse‐midwives, a prevailing punitive culture and underreporting of adverse events. These highlight the need for managers to commit to providing better working conditions, encourage training with the development of a fairer safety culture and encourage reporting and learning from mistakes. There is also a need to invest in team leaders who allow better conflict management and optimization of communication skills is essential. Impact: Disseminating these results will provide relevance to the safety culture problem, allowing greater awareness of nurse‐midwives and managers about vulnerable areas, and lead to the implementation of effective changes for safe maternal and neonatal care. Patient or Public Contribution: There was no patient or public contribution as the study only concerned service providers, that is, nurse‐midwives themselves. [ABSTRACT FROM AUTHOR]

The growing number of older workers affects occupational safety in the context of the construction industry's aging workforce. The first step in proactively reducing safety accidents is hazard detection, which involves visual cognitive processing of preattention and attention. Prior research has shown no consensus on the role of age in hazard detection and safety performance, and few studies have attempted to empirically test how age affects visual cognitive abilities in hazard detection. Electroencephalography (EEG) fills the gap left by earlier methodological shortcomings of subjective evaluation and poor accuracy with a reliable and objective tool for cognitive measurements. Therefore, this study investigated the impact of age on early preattention and later attention in the face of three types of hazards: falling from height, struck-by, and tripping on the same level, based on EEG measurements. Results present the age-related changes in workers' preattentive and attentive abilities for hazard detection varied depending on hazard types. Without being influenced by experience, older workers engaged much stronger preattention than younger workers to fatal hazards (falling from height and struck-by). From the standpoint of preattention inhibition, older workers showed much less inattentional blindness to being struck than younger workers, but such a relationship was mediated by experience. Older workers paid substantially less attention to nonfatal hazards (tripping on the same level) than younger counterparts, and experience had no mediation on this. This study was the first attempt to investigate cognitive-based age differences in hazard detection abilities, including preattention and attention, in construction safety contexts. The effectiveness of EEG signals as indicators of visual cognitive processing in detecting hazards can be examined further. The findings can be used to develop tailored and hazard-focused safety management practices to improve the preattentional and attentional functions of construction workers of different ages.

Developing real-time automatic intuitive devices based on electroencephalography (EEG) to improve hazard recognition performance (HRP) is essential in construction engineering management. However, existing studies generally developed devices based on unimodal data, failing to distinguish the role played by brain activities in different visual areas and ignoring the possible existence of other psychological mechanisms. Therefore, this study aims to use multimodal data based on brain-eye synergy to predict HRP and reveal the cognitive mechanism of hazard recognition to develop intuitive hazard recognition devices. Accordingly, we designed experiments to investigate this problem: (1) 53 construction workers completed a 120-trial hazard recognition task in a laboratory environment (N=6,360), (2) an EEG recorder collected the participants' EEG activities and an eye-tracking device recorded the data of eye movement, and (3) the power spectral density (PSD) of EEG was calculated and then imported into Matlab2018a in combination with EEGLAB for analysis. The results showed that the prediction results of hazard recognition have a time-variant effect. For fall-related hazards, EEG signals within 0–320 ms after the onset were significant in predicting HRP; for electric-related and fire-related hazards, EEG signals within 560–640 ms after the starting point were the most valuable. Also, compared with fall-related hazards, it took a significantly longer time to recognize electric-related and fire-related hazards, which consumed more attentional resources. Finally, the frontal lobe requires more attentional resources to finish cognitive activities than the occipital lobe to finish visual information processing activities, and the occipital lobe needs to process visual information first, and then transmit it to the frontal lobe for analysis and judgment. For the body of knowledge, this study, finding the time-variant effect of HRP, improves the theory of construction hazard recognition from an eye-brain synergy perspective and provides guidance for developing intuitive hazard recognition devices and improving management performance. This study combined eye-movement data and EEG data to predict the performance of hazard recognition using multimodal data. Not only did this study reveal the mechanism of hazard recognition, but it also proposed suggestions for project management and device development. Managers are suggested to implement refined management and regularly monitor the physiological signals of employees. Some construction companies started to use smart devices to measure workers' arousal, emotional valence, emotional regulation ability, fatigue, workload, or safety attention level before work every day. And it is recommended to provide safety reminders to employees based on whether there are any abnormalities in their physiological indicators. In addition to project management, the results of this study can serve the development or optimization of hazard recognition equipment. Developing devices cannot only consider EEG information, but also combine EEG information with eye-movement information. Meanwhile, developers can also consider different types of hazards and different brain regions to improve device performance. [ABSTRACT FROM AUTHOR]

Background: Nurses have faced significant personal and professional stressors during the COVID-19 pandemic that have contributed to increased rates of burnout, intention to leave, and poorer work engagement. Resilience has been identified as a critical factor influencing job outcomes; however, the dynamics of this association have not yet been investigated within the context of the Thai workforce. The study objective was to determine the associations between resilience and job outcomes, including burnout, intention to leave, and work engagement among nurses working in Thailand during the COVID-19 pandemic. Methods: This cross-sectional study gathered data from a sample of 394 registered nurses employed across 12 hospitals. The research instruments comprised the Connor–Davidson Resilience Scale (CD-RISC), the Maslach Burnout Inventory-Health Services Survey (MBI-HSS), a questionnaire assessing the intention to leave the job, and the Utrecht Work Engagement Scale (UWES). To determine the associations among the measured variables, multivariate logistic regression analyses were conducted. Results: One-third of nurses experienced emotional exhaustion and depersonalization, and about half experienced reduced personal accomplishment; one-tenth of nurses intended to leave their job. Nurses who exhibited higher levels of resilience were found to have a significantly reduced likelihood of experiencing high emotional exhaustion, depersonalization, and a diminished sense of personal accomplishment. Conversely, these nurses were more likely to report higher levels of work engagement than their less resilience. Conclusion: The COVID-19 pandemic offers important lessons learned about promoting the well-being of the nursing workforce and protecting against adverse job outcomes. While we identified resilience as a significant predictor of several nurse outcomes, other work environment factors should be considered. Government and hospital administrations should allocate resources for individual and organizational-level interventions to promote resilience among frontline nurses so that hospitals will be better prepared for the next public health emergency and patient and nurse outcomes can be optimized.

Background: Implementing appropriate shift work schedules can help mitigate the risk of sleep impairment and reduce fatigue of healthcare workers, reducing occupational health and safety risks. In Australia, the organisation has a responsibility to make sure all reasonable measures are taken to reduce fatigue of staff. Therefore, it is important to assess what the current rostering processes is for staff responsible for creating the rosters for nurses. Aim: The aims of the project were to understand (1) who creates the rosters and what the process is, (2) what training and knowledge these staff have in establishing rostering schedules that optimise the sleep and wellbeing of staff, and (3) what the benefits and limitations are of current rostering practices. Methods: Findings were generated through semi-structured interviews, using cluster coding to form categories. Twenty four nurses responsible for rostering staff were interviewed from three different sites in Victoria (one metropolitan and two regional/rural hospitals). Data was analysed using selected grounded theory methods with thematic analysis. Results: The common themes that came out of the interviews were that rostering staff were under prepared, unaware of fatigue and safety guidelines and polices from governing bodies and had not received any education or training before taking on the role. The most common rostering style was self-rostering, where staff could submit preferences. However, there were concerns about staff fatigue but were divided as to who should be responsible, with many saying it was up to staff to preference shifts that they could cope with. The final theme was cultural barriers to change. Conclusion: While self-rostering resulted in staff having more freedom and flexibility, shift preferences may be influenced more so by a need to fit with lifestyle rather than to minimise fatigue and increase safety in the workplace. Greater consideration of the impact of shift work schedules on fatigue is required to ensure that the layers of clinical governance in health care organisations minimise the risk of occupation health and safety issues for employees delivering direct patient care.

In radiotherapy, when photon energy exceeding 8 MV is utilized, photoneutrons can activate the components within the gantry of the linear accelerator (linac). At the end of the linac's lifecycle, radiation workers are tasked with its dismantling and disposal, potentially exposing them to unintentional radiation. This study aims to identify and measure the radioisotopes generated by this activation through spectroscopy, and to evaluate the effective dose rate. We selected nine medical linacs, considering various factors such as manufacturer (Siemens, Varian, and Elekta), model, energy, period of operation, and workload. We identified the radionuclides in the linac head by employing an in situ high-purity germanium (HPGe) detector. Spectroscopy and dose-rate measurements were conducted post-shutdown. We also measured the dose rates at the beam-exit window following irradiation with 10 MV and 15 MV photon beams. As a result of the spectroscopy, we identified approximately 20 nuclides including those with half-lives of 100 days or longer, such as 54Mn, 60Co, 65Zn, 122Sb, and 198Au. The dose rate measurements after 10 MV irradiation decreased to the background level in 10 min. By contrast, on 15 MV irradiation, the dose rate was 628 nSv/h after 10 min and decreased to 268 nSv/h after 1.5 hours. It was confirmed that the difference in the level of radiation and the type of nuclide depends on the period of use, energy, and workload. However, the type of nuclide does not differ significantly between the linacs. It is necessary to propose appropriate guidelines for the safety of workers, and disposal/move-install should be planned while taking into consideration the equipment's energy usage rate.

Traditional optical flame detectors (OFDs) in flame detection are susceptible to environmental interference, which will inevitably cause detection errors and miscalculations when confronted with a complex environment. The conventional deep learning-based models can mitigate the interference of complex environments by flame image feature extraction, which significantly improves the precision of flame recognition. However, these models focus on identifying the general profile of the static flame, but neglect to effectively locate the source of the dynamic flame. Therefore, this paper proposes a novel dynamic flame detection method named Dynamic Deformable Adaptive Framework (DDAF) for locating the flame root region dynamically. Specifically, to address limitations in flame feature extraction of existing detection models, the Deformable Convolution Network v2 (DCNv2) is introduced for more flexible adaptation to the deformations and scale variations of target objects. The Context Augmentation Module (CAM) is used to convey flame features into Dynamic Head (DH) to feature extraction from different aspects. Subsequently, the Layer-Adaptive Magnitude-based Pruning (LAMP) where the connection with the smallest LAMP score is pruned sequentially is employed to further enhance the speed of model detection. More importantly, both the coarse- and fine-grained location techniques are designed in the Inductive Modeling (IM) to accurately delineate the flame root region for effective fire control. Additionally, the Temporal Consistency-based Detection (TCD) contributes to improving the robustness of model detection by leveraging the temporal information presented in consecutive frames of a video sequence. Compared with the classical deep learning method, the experimental results on the custom flame dataset demonstrate that the AP0.5 value is improved by 4.4%, while parameters and FLOPs are reduced by 25.3% and 25.9%, respectively. The framework of this research extends applicability to a variety of flame detection scenarios, including industrial safety and combustion process control. [ABSTRACT FROM AUTHOR]

Disturbance stress assessment is crucial for ensuring the safety of deep engineering projects. Currently, the primary technique for continuously monitoring three-dimensional disturbance stress is the stress relief method, but its accuracy can be compromised by rock damage that occurs after excavation. To mitigate this issue, grouting is employed to repair damaged rock masses and enhance their mechanical properties. However, the impact of grouting techniques on improving the accuracy of disturbance stress testing is challenging to evaluate through laboratory and in situ experiments. To address this problem, numerical simulation technology is employed to investigate disturbance stress testing after the repair of damaged surrounding rock through grouting. The simulation results indicate that grouting repair significantly enhances the accuracy of stress testing. As the depth of damaged rock mass repair increases, the error in stress testing decreases. Achieving complete repair of the initial damage zone during grouting is essential to eliminate errors in stress testing. Expanding on the positive effects of grouting repair on stress testing, a segmented testing method for disturbance stress is proposed. The method involves separately testing the initial stress and stress changes, thereby reducing the stress level within the rock, minimizing rock failure, and enhancing the accuracy of disturbance stress testing. This study provides valuable reference methods, and the outcomes of this research will serve as a foundation for enhancing the accuracy of disturbance stress testing in deep hard rock engineering.

CO2 sensors are very important; however, their performance is limited by stability and selectivity. This study unveils a capacitive CO2 sensor with a dielectric layer comprised of amine-functionalized cellulose nanofibril (CNF) foam, significantly enhanced by the addition of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU). The core innovation of this research lies in the strategic use of CNF-based foam, which leads to a substantial increase in sensor capacitance, setting a new standard in CO2 monitoring technologies. The sensor showcases exceptional performance under ambient conditions, with marked improvements in sensitivity towards CO2. The advancements are attributed to the chemisorption properties of the aminated CNFs combined with the DBU enhancement, facilitating more effective CO2 capture. By integrating these materials, we present a sensor that opens new avenues for environmental monitoring, healthcare diagnostics, and industrial safety, establishing a new benchmark for capacitive CO2 sensors in efficiency and environmental sustainability.

Background: Sawmill workers are at increased risk of occupational injuries due to their exposure to workplace hazards. However, little is known about the burden of occupational injuries among them in Ghana. Understanding its prevalence and associated factors is necessary to design appropriate interventions to improve workers' health and safety. This study sought to determine the prevalence and factors associated with occupational injuries among small-scale sawmill workers at Sokoban Wood Village, Kumasi. Methods: A cross-sectional study was conducted among 138 small-scale sawmill workers from December 2020 to January 2021. Data was collected on demographic and work-related characteristics including age, sex, personal protective equipment (PPE), workspace design, and lighting. The primary outcome was the prevalence of occupational injuries in the 12 months preceding the survey. Logistic regression method was used to assess for independent predictors of occupational injuries, and associations were deemed statistically significant at p < 0.05. Results: Approximately 66.7% of the workers experienced occupational injuries within the 12 months preceding the study. Cuts (69.6%) were the most commonly reported injuries. Injuries were mainly caused by machine parts/sharp objects (47.8%) and being hit by logs/objects (46.8%). Only 40.7% of the workers reported always using PPE while legs (38.0%) and hands (37.0%) were the most common body parts injured. The worker's monthly income, poor workspace design and poor lighting had increased odds of occupational injuries while an increase in age was associated with a 5% decreased odds of occupational injuries. Conclusion: The prevalence of occupational injuries among the sawmill workers at the Sokoban Wood Village was high, and this calls for prioritization of health and safety at the workplace. Essential measures required include improvements in the safety of machine tools, workspace design and lighting. [ABSTRACT FROM AUTHOR]

Occupational illnesses and occupational injuries remain significant problems in contemporary countries. Especially in the fourth industrial revolution, with the changing technology and business model requirements, employees are at more risk because they have to be much faster and fulfill different functions. Due to present risks, dangerous working conditions, and inadequate measures, each year hundreds of thousands of people suffer from occupational illnesses or have occupational accidents. While occupational health and safety (OHS) practices protect employees, it is possible to increase productivity by ensuring that employees work in a safe and healthy work environment with the Lean Occupational Safety approach based on the "Zero Accident" principle. In this paper, a case study is presented by using a Lean-OHS model that it is an original model that incorporates continuous improvement by taking advantage of lean philosophy, tools and techniques while fulfilling the OHS principles. The research was carried out in a university's pharmacology and pharmaceuticals laboratory, and it improved working conditions and made the workplace safer by turning 18 of 20 threats into acceptable ones.

Objective: In this study, we aim to develop and propose an evaluation method for analyzing the design of operating rooms (ORs) from the perspective of surgical teams' reported experiences and stress levels. Background: Stress and burnout of surgical team members can lead to diminished performance and medical errors, which endangers the safety of both the patients and team members. The design and layout of the OR play a critical role in managing such stress. Methods: To understand surgical teams' spatial needs related to their experiences and stress, we administered a survey and in-depth focus group discussions to three surgical teams from the same organization. The identified spatial needs were translated into functional scenarios and spatial metrics, essentially viewing the OR through the perspective of users. Results: Our analysis revealed four integral sections—patient flow, room organization, access to facilities/medical equipment/support staff/team members, and staff well-being—identified as critical design factors associated with the experiences and stress levels of the surgical teams in the ORs. Conclusions: We expect this method to serve as a tool for evaluating the effect of the design of OR layouts on stress, thereby supporting the well-being and resiliency of surgical teams.

A lack of recovery like psychologically detaching from work can be detrimental to health. High cognitive demands may jeopardise detachment from work. Longitudinal studies concerning the long-term effects of cognitive demands on health and work ability via psychological detachment are understudied. Research has shown that social support may buffer the relationship between job demands and psychological detachment. However, the role of supervisor support was not examined specifically. We hypothesise psychological detachment to mediate the relationship between cognitive demands, general health, and work ability. Supportive or inconsiderate behaviours of a supervisor can further moderate the relationship between cognitive demands and psychological detachment. Statistical analyses were carried out with three-wave panel data from the German Federal Institute for Occupational Safety and Health with lags of two years (2015–2019) from 3,867 employees who took part in the survey. The results conveyed that mediation by psychological detachment was significant, while supervisor (non)support moderated the relationship between cognitive demands and psychological detachment only cross-sectionally. This study emphasises the role of supervisor in the stressor-detachment model and the positive effect of recovery experience on health. Therefore, in practice, the role of supervisor behaviour for employees' psychological detachment should be addressed in management training courses. [ABSTRACT FROM AUTHOR]

Background and Objectives: As the COVID-19 pandemic brought surges of hospitalized patients, it was important to focus on reducing overuse of tests and procedures to not only reduce potential harm to patients but also reduce unnecessary exposure to staff. The objective of this study was to create a Choosing Wisely in COVID-19 list to guide clinicians in practicing high-value care at our health system. Methods: A Choosing Wisely in COVID-19 list was developed in October 2020 by an interdisciplinary High Value Care Council at New York City Health + Hospitals, the largest public health system in the United States. The first phase involved gathering areas of overuse from interdisciplinary staff across the system. The second phase used a modified Delphi scoring process asking participants to rate recommendations on a 5-point Likert scale based on criteria of degree of evidence, potential to prevent patient harm, and potential to prevent staff harm. Results: The top 5 recommendations included avoiding tracheal intubation without trial of noninvasive ventilation (4.4); not placing routine central venous catheters (4.33); avoiding routine daily laboratory tests and batching laboratory draws (4.19); not ordering daily chest radiographs (4.17); and not using bronchodilators in the absence of reactive airway disease (4.13). Conclusion: We successfully developed Choosing Wisely in COVID-19 recommendations that focus on evidence and preventing patient and staff harm in a large safety net system to reduce overuse.
