Drawing parallels to the theory of heart zone training for exercise, this essay advocates for slowing down when making the majority of decisions in the workplace. In making the case for slower decision making, the author shares theories from change management and practices targeted toward enhancing inclusivity. While there are situations when decisions should be made quickly or delegated to others, the author maintains that leaders should take their time when making decisions. [ABSTRACT FROM AUTHOR]

Abstract In South Korea, the snowy season spans from October to April, and the annual average snowfall varies significantly depending on specific regions, latitudes, and elevations, ranging from 0 to 260 cm. The average annual snowfall in South Korea is 25.1 cm. Despite of the relatively shallow snowfall depth, over the past decade, South Korea has experienced approximately 120 million dollars in damages attributed to snow-related incidents. In this study, the DPSIR (Driver-Pressure-State-Impact-Response) framework was employed to consider the meteorological and socioeconomic factors to calculate the snow damage vulnerability. A total of 17 indicators were taken into account to comprehend meteorological conditions, socioeconomic factors, and historical damage records from 1994 to 2020. However, due to the limited availability of meteorological observatories and changes in greenhouse design standards, accurately estimating the snow damage amount poses challenges. Therefore, based on the vulnerability, the risk levels were classified into four categories and estimated snow damage generated by the categorized models was compared with those of the model constructed using the entire dataset. The categorized models offer improved estimation results, as the meteorological and socioeconomic characteristics within each category differ and should be addressed separately in modeling. Among the categorized models, the Green zone exhibited the best results, primarily because it did not include outlier snow damage incidents. The developed model in this study could be utilized to mitigate the impact of heavy snowfall and prioritize snow removal regions.

Coal spontaneous combustion is the main disaster affecting the safety production of mines, and efficient early warning is the key to controlling coal spontaneous combustion disasters. In order to construct an early warning system for spontaneous combustion disasters of coal with different degrees of metamorphism, the programmed-temperature control experiment was conducted to obtain the change curve of the volume fraction of the index gases of the low, medium and high degrees of metamorphosis, and then the Logistic function is used to fit the volume fraction and temperature of the index gases, and the mathematical model of the index gas and temperature of the index gases with different degrees of metamorphism is obtained, and the inflection point temperature is determined, and finally the spontaneous combustion hazard level of the coal is divided in combination with the initial temperature of the index gases. The results show that the changes of coal sample index gases and characteristic temperatures with different degrees of metamorphism are different; the initial appearance temperature of CO is about 30°C, while the initial appearance temperature of C
2 H4 and C2 H2 is positively correlated with the degree of metamorphism, and the initial appearance temperature is 117°C (low), 123°C (medium) and 137°C (high) for C2 H4 , 291°C (low), 297°C (medium) and 297°C (high) for C2 H2 ; For the same marker gas, the inflection point temperature increases with the degree of metamorphism, indicating that the higher the degree of metamorphosis, the less likely it is to oxidize at the beginning; According to the variation characteristics of coal spontaneous combustion, based on the initial emergence temperature of CO and C2 H4 and CO inflection point temperature, coal spontaneous combustion is divided into five states: safe, low risk, medium risk, high risk and catastrophic state, and the energy level transition map between each state indicates that the energy required to transition from safe state to low risk and high risk state is the largest. Once the high-risk state is crossed, it does not require higher energy to maintain the continuous development of spontaneous combustion of coal and evolve into a catastrophic state. The classification of coal spontaneous combustion hazard levels with different degrees of metamorphism can provide prior data and form effective support for intelligent early warning of coal spontaneous combustion.

Road testing can accelerate the development and validation of autonomous vehicles (AVs). AV road testing can come with high safety risks, particularly in a complex road traffic environment, due to the immaturity of AV technology. A priori safety risk assessments of the road traffic environment before AV road testing are of great importance, allow the quantifying of risk levels in different road scenarios, and provide guidelines for AV road testing in low to high-risk environments. This study proposes a framework, namely Safety Risk Assessment for AV road testing (SRAAV), based on the probability and severity of five categories of potential AV accidents. Four groups of influencing factors are considered comprehensively in assessing AV safety risk, and their impacts are quantified using impact coefficients derived from a Bayesian network and empirical AV road testing data. The safety risk is assessed on a road section level, based on which an overall risk level is defined for a corridor and a region. Afterwards, the quantified safety risk is classified into four levels according to expert experience and knowledge, through a questionnaire survey. Applications of the proposed SRAAV framework are conducted for urban roads in Shanghai, and expressways in Shanghai and Gothenburg. The assessment results are validated using disengagement data from AV road testing. The results show that the SRAAV framework and its models could estimate the safety risk levels of road traffic environments for AV road testing in a sound way and have the flexibility for further extensions to be made. The framework and assessment results can provide technical support for determining where and when to grant permission for public roads to be used for AV road testing, and how to choose public roads from a low to a high risk level, guaranteeing the safety of AV public road testing.

Abstract Background Chronic conditions are one of the main determinants of frailty, functional disability, loss of quality of life and the number one cause of death worldwide. This study aimed to describe the survival of patients with chronic conditions who were followed up in primary care according to the level of risk by adjusted morbidity groups and to analyse the effects of sex, age, clinician and care factors on survival. Methods This was a longitudinal observational study of a retrospective cohort of patients with chronic conditions identified by the adjusted morbidity group stratifier of the electronic medical records in a primary health centre of the Region of Madrid, which has an assigned population of 18,107 inhabitants. The follow-up period was from June 2015 to June 2018. A description of survival according to the Kaplan–Meier method and Cox proportional hazards multivariate regression model was used to analyse the effects of sex, age, clinician and care factors. Results A total of 9,866 patients with chronic conditions were identified; 77.4% (7,638) had a low risk, 18.1% (1,784) had a medium risk, and 4.5% (444) had a high risk according to the adjusted morbidity groups. A total of 477 patients with chronic conditions died (4.8%). The median survival was 36 months. The factors associated with lower survival were age over 65 years (hazard ratio [HR] = 1.3; 95% confidence interval [CI] = 1.1–1.6), receiving palliative care (HR = 3.4; 95% CI = 2.6–4.5), high versus low risk level (HR = 2.4; 95% CI = 1.60–3.7), five chronic conditions or more (HR = 1.5; 95% CI = 1.2-2), complexity index (HR = 1.01; 95% CI = 1.02–1.04) and polymedication (HR = 2.6; 95% CI = 2.0-3.3). Conclusions There was a gradual and significant decrease in the survival of patients with chronic conditions according to their level of risk as defined by adjusted morbidity groups. Other factors, such as older age, receiving palliative care, high number of chronic conditions, complexity, and polymedication, had a negative effect on survival. The adjusted morbidity groups are useful in explaining survival outcomes and may be valuable for clinical practice, resource planning and public health research.

Humans are facing increasing supply–demand risks of ecological products (EPs) due to the uncertainty of the interaction between ecosystems and social systems. To address this issue, a comprehensive framework for risk assessment and regulation is urgently need to identify areas and levels of risk that threaten human well-being. In this study, we constructed a framework for retrospective assessment and optimal regulation of supply–demand risks of EPs, which covers four indicators: the supply–demand index (SDI), the changing trend of SDI, the changing trend of supply, and trade-offs and synergies. Taking Qinghai Province in the northeast of the Qinghai-Tibet Plateau in China as an example, we conducted a case study on five types of EPs: food production, water conservation, carbon sequestration, soil retention, and outdoor recreation. Our results showed that various types of EPs were basically in the state of supply exceeds demand, with significant spatial differences in supply–demand risk levels. Areas with high risk levels were mainly distributed in urban concentrated development areas in the eastern part of the research area, and the spatial matching of supply and demand in these areas often present high supply and high demand. In addition, for the supply–demand risk of different levels of EPs, we proposed intra-regional and cross-regional optimization regulation strategies, combining the spatial matching status of supply and demand of EPs. It can help decision-makers improve the efficiency of the allocation of EPs supply and demand and the scientific nature of policy formulation at a regional scale.

Abstract Background Patients with chronic diseases have increased needs for assistance and care. The objective of this study was to describe the characteristics and use of primary care (PC) and hospital care (HC) health services by chronic patients according to risk level based on adjusted morbidity groups (AMG) and to analyze the associated factors. Methods Cross-sectional descriptive observational study. Patients from a basic health area classified as chronically ill by the AMG classification system of the Madrid PC electronic medical record were included. Sociodemographic, clinical-care characteristics (classified as predisposing factors or need factors) and service utilization variables were collected. Univariate, bivariate and simple linear regression analyses were performed. Results The sample consisted of 9866 chronic patients and 8332 (84.4%) used health services. Of these service users, 63% were women, mean age was 55.7 (SD = 20.8), 439 (5.3%) were high risk, 1746 (21.2%) were medium risk, and 6041(73.4%) were low risk. A total of 8226 (98.7%) were PC users, and 4284 (51.4%) were HC users. The average number of annual contacts with PC was 13.9 (SD = 15); the average number of contacts with HC was 4.8 (SD = 6.2). Predisposing factors associated with services utilization at both care levels were: age (B coefficient [BC] = 0.03 and 0.018, 95% CI = 0.017–0.052 and 0.008–0.028, respectively, for PC and HC) and Spanish origin (BC = 0.962 and 3.396, 95% CI = 0.198–1.726 and 2.722–4.070); need factors included: palliative care (BC = 10,492 and 5047; 95% CI = 6457–14,526 and 3098-6995), high risk (BC = 4631 and 2730, 95% CI = 3022–6241 and 1.949–3.512), number of chronic diseases (BC = 1.291 and 0.222, 95% CI = 1.068–1.51 and 0.103–0.341) and neoplasms (BC = 2.989 and 4.309, 95% CI = 1.659–4.319 and 3.629–4.989). Conclusions The characteristics and PC and HC service utilization of chronic patients were different and varied according to their AMG risk level. There was greater use of PC services than HC services, although utilization of both levels of care was high. Service use was related to predisposing factors such as age and country of origin and, above all, to need factors such as immobility, high risk, and number and type of chronic diseases that require follow-up and palliative care.

There has been an emerging interest by financial institutions to develop advanced systems that can help enhance their anti-money laundering (AML) programmes. In this study, we present a self-organising map (SOM) based approach to predict which bank accounts are possibly involved in money laundering cases, given their financial transaction histories. Our method takes advantage of the competitive and adaptive properties of SOM to represent the accounts in a lower-dimensional space. Subsequently, categorising the SOM and the accounts into money laundering risk levels and proposing investigative strategies enables us to measure the classification performance. Our results indicate that our framework is well capable of identifying suspicious accounts already investigated by our partner bank, using both proposed investigation strategies. We further validate our model by analysing the performance when modifying different parameters in our dataset.

Compliance with new regulations in old plants remains a recurring challenge because of negative outcome of incidents. This challenge stems from uncertainties in the facilities' integrity, owing to inadequacy of existing integrity-validating technologies. Process facilities deteriorate through cyclic operations, while encroachments from expanding population characteristically raise the risk-levels, leading to need for higher grade materials to meet operational expansions. Retroactive compliance becomes a nightmare with every new regulation without a robust cost-to-benefit assurance. This paper discusses two-phased qualitative and quantitative risk modelling approach through systematic field-data-gathering, hazards identification and analysis by a twelve-man risk management engineers. The methodology successfully computed a "health-check" of the facility's compliance to new regulations, 17 high-risk-hazards were extracted from 42 potential hazards and successfully established varied individual risk levels ranging from 4.07E-06 to 1.64E-04/year. Also, risks ranged from 1.00E-04 to 5.00E-05/year of tolerable risks to the environment, society, and business were recorded across the facility while, 22 risk-mitigation actions were recommended.

The issue of credit risk management becomes especially relevant for the banking system of Ukraine nowadays, in the context of opening up the worldwide economic space. The objective need to improve the efficiency of bank’s credit risk management requires improvement of the legal, methodological, and organizational foundations of banking activity. The carried out research discloses the nature and place of credit risk among bank risks, its specific characteristics, and the factors of influence upon. The article emphasizes that, in order to make the functioning of bank efficient, credit risk should not be perceived as the probability of a negative event or danger, but rather as the income-generating activity. The main elements of the credit risk management system have been provided. The types and levels of credit risk have been distributed by the classification attributes. The role of internal and external environment factors influencing the bank lending policy has been explored. The role of the credit risk management strategy and tactics has been emphasized. The stages of the credit risk management strategy, its main methods and tools have been disclosed. Ways to successfully implement the credit risk management strategy for contemporary banks have been determined.

- Abstract
Gender-based violence has been defined by the United Nations as any harmful act based on socially ascribed gender differences. Among its many manifestations, that violence in its maximum expression goes as far as femicide; a phenomenon that far from diminishing, has spread around the world. On the other hand, artificial intelligence has appeared on the scene in various sectors, with the legal field being no exception. The connection between gender-based violence and artificial intelligence goes hand in hand with the growing prevention needs of the former, through, for example, the prediction of risk levels in which the latter offers important advantages. Using a deductive qualitative methodology with an exploratory descriptive scope, in which methods from law and computer science are applied to analyze primary and secondary sources and case studies of algorithms and risk assessment tools (without leaving aside the reference to traditional prediction tools that do not use artificial intelligence), the results show that the algorithms and tools mentioned evaluate and weight situational factors and triggers, related to the perpetrator, the victim, and the family relationship; The criticisms are standardized in terms of the accuracy and reliability of the prediction., La Violencia basada en género, ha sido definida por la Organización de las Naciones Unidas como cualquier acto dañino basado en las diferencias de género atribuidas socialmente. Dentro de sus muchas manifestaciones, aquella violencia en su máxima expresión llega hasta el feminicidio; fenómeno que lejos de disminuir, se ha extendido alrededor del mundo. Por otra parte, la inteligencia artificial ha aparecido en la escena de diversos sectores, sin que el ámbito jurídico haya sido la excepción. La conexión entre la violencia basada en género y la Inteligencia artificial se da de la mano de las necesidades crecientes de prevención de la primera, a través por ejemplo de la predicción de niveles de riesgo en la que la segunda ofrece importantes ventajas. Utilizando una metodología cualitativa deductiva con alcance descriptivo exploratorio, en la que se aplican métodos propios del derecho y las ciencias computacionales para analizar fuentes primarias, secundarias y estudio de casos de algoritmos y herramientas de evaluación de riesgo, (sin dejar de lado la referencia a herramientas de predicción tradicionales que no utilizan Inteligencia artificial), se arriba a resultados que apuntan a que los algoritmos y herramientas mencionadas evalúan y ponderan factores situacionales y disparadores, relacionados con el perpetrador, la víctima, y la relación familiar; variando en el valor asignado a cada uno de estos; en cuanto a las críticas se encuentran estandarizadas en la precisión y confiabilidad de la predicción.

HAZARDS , *CHARACTER , *OBJECT manipulation - Abstract
It has been demonstrated that perception of objects automatically evokes potential actions to interact with those objects; this is termed as affordance. The present study investigated how the corresponding affordance effect of graspable objects was modulated by the cue about risk levels of object. Participants were presented with pictures of dangerous graspable objects or neutral graspable objects. The participants were required to perform an upright/upside down discrimination task by pressing different keys. Results showed that both the affordance effects of dangerous object and neutral object in children were enhanced when a cue preceded the object, t(35) = 3.83, p <.01, Cohen's d = 1.29. These results indicate that the prompt of risk level can improve individual's appropriate manipulation to the object. [ABSTRACT FROM AUTHOR]

The objective of this study is to develop a driving fatigue strain index using fuzzy logic to analyze the risk levels of driving activity among road users. Driving fatigue is always related to the driving activity and has been identified as one of the vital contributors to the road accidents and fatalities in Malaysia. Therefore, the present article introduces the use of fuzzy logic for the development of strain index to provide the systematic analysis and propose an appropriate solution in minimizing the number of road accidents and fatalities. The development of strain index is based on the six risk factors associated with driving fatigue; muscle activity, heart rate, hand grip pressure force, seat pressure distribution, whole‐body vibration, and driving duration. The data are collected for all the risk factors, and consequently the three conditions or risk levels are defined as 'safe', 'slightly unsafe', and 'unsafe'. A membership function is defined for each fuzzy condition. IF‐THEN rules were used to define the input and output variables, which correspond to physical measures. This index is a reliable advisory tool for providing analysis and solutions to driving fatigue problem, which constitutes the first effort toward the minimization of road accidents and fatalities. © 2019 Institute of Electrical Engineers of Japan.

Animals can adjust their behaviours depending on ecological context (i.e., behavioural plasticity), and an individual's response to a given context may also vary from occasion to occasion (intra‐individual variability). Recognizing the roles of both behavioural plasticity and intra‐individual variability is important in understanding how behavioural diversity is maintained within populations. However, how the ecological context itself influences the individual behavioural response and intra‐individual variability (e.g., how variable an individual is in their behavioural expression) remains largely unexplored. Here, we examine boldness expression (the duration of startle response) in a specialised spider‐eating jumping spider, Portia labiata, across three contexts following a mild disturbance: presence of a conspecific intruder (most dangerous), environmental change but no conspecific intruder, and no conspecific intruder or environmental change (safest). We found that context does not significantly influence the average boldness expression at the population level. However, each individual responded to each context differently, and the repeatability of boldness expression—the proportion of behavioural variation attributable to the between ‐individual level—is context‐dependent. We also found that in the presence of a conspecific intruder, spiders behave less predictably than in the environmental change context, but not differently from the safest context. These findings may suggest that the presence of conspecifics influences behavioural consistency in individuals, but that this may occur without influencing the population average behaviour.

The aim of this concept paper is the description of a new tool to support institutions in the implementation of targeted countermeasures, based on quantitative and multi-scale elements, for the fight and prevention of emergencies, such as the current COVID-19 pandemic. The tool is a cloud-based centralized system; a multi-user platform that relies on artificial intelligence (AI) algorithms for the processing of heterogeneous data, which can produce as an output the level of risk. The model includes a specific neural network which is first trained to learn the correlations between selected inputs, related to the case of interest: environmental variables (chemical–physical, such as meteorological), human activity (such as traffic and crowding), level of pollution (in particular the concentration of particulate matter) and epidemiological variables related to the evolution of the contagion. The tool realized in the first phase of the project will serve later both as a decision support system (DSS) with predictive capacity, when fed by the actual measured data, and as a simulation bench performing the tuning of certain input values, to identify which of them led to a decrease in the degree of risk. In this way, we aimed to design different scenarios to compare different restrictive strategies and the actual expected benefits, to adopt measures sized to the actual needs, adapted to the specific areas of analysis and useful for safeguarding human health; and we compared the economic and social impacts of the choices. Although ours is a concept paper, some preliminary analyses have been shown, and two different case studies are presented, whose results have highlighted a correlation between NO2, mobility and COVID-19 data. However, given the complexity of the virus diffusion mechanism, linked to air pollutants but also to many other factors, these preliminary studies confirmed the need, on the one hand, to carry out more in-depth analyses, and on the other, to use AI algorithms to capture the hidden relationships among the huge amounts of data to process.

Polish accession to the European Union allowed Polish municipalities to use co-financing of development projects of local infrastructure, environmental protection and improvement of competitiveness of municipalities. The process of transition is sometimes referred to as bridging the development gaps between countries of "old fifteen" and the new member countries. The desire of municipalities to maximize the use of EU funds led to a rapid increase in the debt level of municipalities and changes in levels of risk of long-term liabilities of municipalities. The aim of this article is to empirically confirm thesis that the change in the long-term financial liabilities associated with the prospect of the European Union budget for 2007-2013 is causing a variation of the operating risks of these liabilities. A tool used to verify this hypothesis is the risk model, which is a random vector with components identified with control variables of management process in the handling of long-term financial liabilities. The design of the components of this vector is based on the basic characteristics of the probability distribution of the vector as the ex-pected value and the variance and their ideal and anti-ideal levels.

Introduction: Patients with symptomatic heart failure (HF) require additive therapies and have a poor prognosis. However, patient characteristics and clinical outcome between HF patients treated in the outpatient setting vs. those who are hospitalized remain scarce.Methods and Results: The BIOlogy Study to TAilored Treatment in Chronic Heart Failure (BIOSTAT-CHF) included 2516 patients with symptoms and/or signs of HF: 1694 as inpatients and 822 as outpatients. Compared to ambulatory HF patients, inpatients had higher heart rate, urea, N-terminal pro-brain natriuretic peptide, lower blood pressure, lower estimated glomerular filtration rate, sodium, potassium, high-density lipoprotein cholesterol, had more often peripheral oedema, diabetes, anaemia, and were less often treated with beta-blockers and angiotensin-converting enzyme inhibitors (ACEi). Outpatients had a more frequent history of HF hospitalization and received more frequently beta-blockers and/or ACEi/angiotensin receptor blockers up-titrated to target doses (P < 0.001). Inpatients had higher rates of the primary outcome of death or HF hospitalization: incidence rate per 100 person-years of 33.4 [95% confidence interval (CI) 31.1-35.9] for inpatients vs. 18.5 (95% CI 16.4-21.0) for outpatients; adjusted hazard ratio 1.24 (95% CI 1.07-1.43). Subdividing patients into low, intermediate and high-risk categories, the primary outcome event rates were 14.3 (95% CI 12.3-16.7), 36.6 (95% CI 32.2-41.5), and 71.3 (95% CI 64.4-79.0) for inpatients vs. 8.4 (95% CI 6.6-10.6), 29.8 (95% CI 24.5-36.2), and 43.3 (95% CI 34.7-54.0) for outpatients, respectively. These findings were externally replicated.Conclusions: Marked differences were observed between inpatients and outpatients with HF. Overall, inpatients were sicker and had higher event rates. However, a substantial proportion of outpatients had similar or higher event rates compared to inpatients. These findings suggest that HF outpatients also have poor prognosis and may be the focus of future trials. [ABSTRACT FROM AUTHOR]- Published

Portuguese freshwater reservoirs are important socio-economic resources, namely for recreational use. National legislation concerning bathing waters does not include mandatory levels or guidelines for cyanobacteria and cyanotoxins. This is an issue of concern since cyanotoxin-based evidence is insufficient to change the law, and the collection of scientific evidence has been hampered by the lack of regulatory levels for cyanotoxins in bathing waters. In this work, we evaluate the profile of cyanobacteria and microcystins (MC) in eight freshwater reservoirs from the center of Portugal, used for bathing/recreation, in order to determine the risk levels concerning toxic cyanobacteria occurrence. Three of the reservoirs did not pose a risk of MC contamination. However, two reservoirs presented a high risk in 7% of the samples according to the World Health Organization (WHO) guidelines for MC in bathing waters (above 20 µg/L). In the remaining three reservoirs, the risk concerning microcystins occurrence was low. However, they exhibited recurrent blooms and persistent contamination with MC up to 4 µg/L. Thus, the risk of exposure to MC and potential acute and/or chronic health outcomes should not be disregarded in these reservoirs. These results contribute to characterize the cyanobacterial blooms profile and to map the risk of toxic cyanobacteria and microcystins occurrence in Portuguese inland waters. [ABSTRACT FROM AUTHOR]

The strategic management of commercial companies in times of crisis places a strong emphasis on the management and control of the risk. There is no business activity in the world that is not associated with various types of risk. In a highly competitive and turbulent environment, the clear linking of the business strategy of the firm and its risk management makes it possible to identify and manage the risk of the surrounding environment and the on-going movements within it. Strategic risk management creates a protection value that ensures a sustainable internal environment. This is a continuous process that is embedded in the strategy. [ABSTRACT FROM AUTHOR]

Diseñar el procedimiento de trabajo seguro en alturas para la empresa ITALCOL catalogada como riesgo V basados en la resolución 4272 del 2021, y así poder mitigar la accidentalidad y posible mortalidad en la planta de producción El trabajo en alturas es toda actividad o desplazamiento que realice un trabajador mientras se encuentre expuesto a un riesgo de caída de distinto nivel con altura mayor o igual a dos metros, por esto el trabajo en alturas se encuentra catalogado como un trabajo de alto riesgo, no solo por las condiciones en que se lleva a cabo sino porque aún es muy difícil generar una conciencia preventiva en quien lo realiza; es por esto que es de suma importancia la disminución del riesgo que con lleva a la materialización de accidentes de trabajo. El principal objetivo de este trabajo es Diseñar el procedimiento de trabajo seguro en alturas para la empresa ITALCOL, catalogada como riesgo V, basados en la resolución 4272 del 2021, y así poder mitigar la accidentalidad y posible mortalidad en la planta de producción, bajo la metodología mixta descriptiva, Adicional a esto se requirió realizar un proceso de observación en campo, enfocado en verificar las condiciones reales en las que se realizan las actividades de trabajo en alturas, identificando las acciones de mejora que se implementaron y con esto garantizar que las actividades se desarrollan cumpliendo lo requerido. Con este procedimiento se generó un impacto importante a la compañía mejorando esos factores críticos encontrados a lo largo de este proyecto. Al generar este procedimiento se obtuvieron resultados favorables donde la empresa ITALCOL se comprometió a asumir la divulgación a sus colaboradores, a adquirir los equipos faltantes, mejorar la metodología de capacitación y cumplir con todos los lineamientos nuevos aplicados a las actividades sobre la norma. Work at heights is all activity or displacement performed by a worker while exposed to a risk of falling for a different level with a height greater than or equal to two meters, therefore, work at heights is classified as a high-risk work, not only because of the conditions in which it is carried out but because it is still very difficult to generate a preventive awareness in those who perform it; that is why it is of very importance to reduce the risk that leads to the materialization of accidents at work. The main objective of this work is to design the procedure of safe work at heights for the company ITALCOL cataloged as risk V based on resolution 4272 of 2021, and with this be able to mitigate the accident rate and possible mortality in the production plant under the descriptive qualitative methodology. Additionally, it was required to conduct a process of field observation, focused on verifying the actual conditions in which the activities of work at heights are performed, identifying the improvement actions that were implemented and with this ensure that the activities are developed in compliance with the requirements.

The phenomenon of drought is serious in many landscapes with continental patterns of climate. In fact, drought risk is usually assessed in terms of prevailing issue (meteorological, hydrological, agronomical, etc.) and not in terms of complex landscape features. A procedure for detailed geographical drought risk modelling has been developed using recent meteorological data of dry period and prior precipitations, as well as a digital elevation model and geographic data layers of natural landscape features and land cover. The current version of the procedure starts with meteorological data (temperature and precipitation) processing followed by the use of soil and geological data and land cover, the national CORINE LC 2006 CZ database, for assessing the impact of the local natural features on drought risk. The methodology is based on GIS tools, geodata of the geological structure of the area (water holding capacity of the substrate, the horizontal and vertical water conductivity), soil cover (in agricultural and forested areas, soil types and kinds), landscape cover (land use), relief (digital elevation model and its derivatives), temperature and precipitation data from neighbouring representative meteorological and climate stations. The procedure uses regression equation for temperature and precipitation risk modelling, fuzzy standardization for estimation of different water retention within land cover categories and expert estimation for risk categories within rocks and soils. The final calculation is based on spatial decision-making techniques, especially the weighted sum method with a natural breaks reclassification algorithm. Combining geodata of soils, the geological environment and the active surface with their computed humidity conditions, it is possible to identify areas with a graded risk of geographic drought. The final results do not represent partial values, but identify five risk classes in the study area illustrating a possible level of geographical drought risk. [ABSTRACT FROM AUTHOR]

This paper investigates the power of the computer guided clinical interview (CI) and new curriculum based measurement (CBM) measures to identify and help children at risk of low mathematics achievement. We use data from large numbers of children in Kindergarten through Grade 3 to investigate the construct validity of CBM risk categories. The basic issue is whether the CBM measures assign children correctly to the basic risk categories of At Risk, Emerging, and On Track. The data show that the CBM can be useful for identifying children at risk, but that the CI offers insight into the cognitive processes underlying student difficulties. The CI is particularly useful for identifying children whose underlying mathematical reasoning is more competent than their overt performance. Information of this type is more valuable for teachers than simply learning that a student is at risk. [ABSTRACT FROM AUTHOR]

Objective Patients with endometrioid endometrial cancer are stratified as high risk and low risk for extrauterine disease by surgical staging. Since patients with low-grade, minimally invasive disease do not benefit from comprehensive staging, pre-surgery stratification into a risk category may prevent unnecessary surgical staging in low risk patients. Our objective was to develop a predictive model to identify risk levels using somatic mutations that could be used preoperatively. Methods We classified endometrioid endometrial cancer patients in The Cancer Genome Atlas (TCGA) dataset into high risk and low risk categories: high risk patients presented with stage II, III or IV disease or stage I with high-intermediate risk features, whereas low risk patients consisted of the remaining stage I patients with either no myometrial invasion or low-intermediate risk features. Three strategies were used to build the prediction model: 1) mutational status for each gene; 2) number of somatic mutations for each gene; and 3) variant allele frequencies for each somatic mutation for each gene. Results Each prediction strategy had a good performance, with an area under the curve (or AUC) between 61% and 80%. Analysis of variant allele frequency produced a superior prediction model for risk levels of endometrial cancer as compared to the other two strategies, with an AUC = 91%. Lasso and Ridge methods identified 53 mutations that together had the highest predictability for high risk endometrioid endometrial cancer. Conclusions This prediction model will assist future retrospective and prospective studies to categorize endometrial cancer patients into high risk and low risk in the preoperative setting.

The purpose of the present thesis is to assess the determinants of the Portuguese bank’s capital ratio and risk level. To do so, and based on previous papers developed by Shrieves & Dahl (1992), Rime (2001) e Heid (2004), we estimate a simultaneous equations model with partial adjustments for capital and risk. The observed changes in capital and risk are a product of discretionary behaviour of the banks and exogenous shocks. By building a panel-data of the Portuguese banks between 2008 and 2019, we examine though the Arellano Bond estimator and the 3SLS estimator the factors contributing to the bank’s capital and risk levels. Our main results indicate that the banks’ size has a significant impact on both capital and risk level. Moreover, the regulatory pressure has an expected positive impact when determining the banks’ capital ratio, in-line with the buffer theory meaning banks with a low buffer tend to raise their capital levels and banks with a higher capital buffer tend to maintain it to avoid breaching regulation and facing sanctions from regulatory authorizes. From 2017 to 2019 there is a significant increase in capital levels transversal to all banks, that may be related to the final implementation of Basel III Accord combined with a positive economic climate. We also are able to say that capital levels adjust very quickly with regard to capital levels from the previous period, however risk does not. A presente tese tem como objetivo identificar os fatores determinantes nos níveis de risco e capital dos bancos portugueses. Com base em literatura previa desenvolvida por Shrieves & Dahl (1992), Rime (2001) e Heid (2004), estimamos um modelo de equações simultâneas com ajustes parciais para o capital e o risco. As variações do capital e risco são um resultado do comportamento interno dos bancos e de choques exógenos. Com base nos dados de painel dos bancos portugueses de 2008 a 2019, analisamos através do estimador de Arelleno Bond e de 3SLS que fatores contribuem para os níveis de capital e risco dos bancos. Os resultados indicam-nos que a dimensão do banco tem um impacto significativo no capital e no risco. Também a pressão exercida pelos reguladores tem um impacto positivo, como era esperado na nos níveis de capital, esta conclusão vai de encontro com a "buffer theory" que defende que bancos com baixos níveis de capital tendem a aumentá-lo, enquanto os bancos com uma almofada elevada de capital tendem a mantê-la para evitar entrarem em incumprimento e sofrer sanções das entidades reguladoras. De 2017 a 2019 é possível observar um aumento de capital transversal a todos os bancos, isto pode-se dever ao fato de terem sido implementadas as últimas alterações do Acordo de Basileia III aliado a um clima económico favorável. Podemos afirmar que os níveis de capital têm um ajusto rápido, comparando com os níveis de capital do período anterior, algo que não se verifica com o risco.

In this study, using four wave longitudinal data, we examined problem gambling severity trajectories in a sample of young adults. Using latent growth curve modeling, we examined how initial level of problem gambling severity and the rate of change were affected by 11 time-invariant predictors: gender, age of onset of gambling, experiencing a big win early in gambling career, experiencing a big loss early in gambling career, alcohol dependence, drug dependence, anxiety, depression, perceived social support, illusion of control, and impulsiveness. Five of the eleven predictors affected initial levels of problem gambling severity; however only impulsiveness affected the rate of change across time. The mean trajectory was negative (lessening of problem gambling risk severity across time), but there was significant inter-individual variation in trajectories and initial levels of problem gambling severity. The main finding of problem gambling risk diminishing over time challenges the conventional picture of problem gambling as an inevitable "downward spiral," at least among young adults, and suggests that targeted prevention campaigns may be a cost-effective alternative for reaching treatment resistant youth.

In general, it is important to understand drivers of safety performance. The issue of hydrocarbon leaks on offshore platforms is one of the most important safety performance indicators based on risk related to major accidents. In this study, a longitudinal design was used to investigate the relationships between work climate and hydrocarbon leaks from a broader organizational perspective. Confirmatory factor analyses tested on a sample of offshore workers ( N = 3320), supported the validity of the Scandinavian Work Climate Instrument (SWCI). Complementary results also supported the measurement model. Pearson’s correlations indicated significant associations between work climate dimensions and hydrocarbon leaks occurring in the post survey period. All correlations were negative, supporting the proposed hypothesis. Generally, the results supported the assumption and model that guided the overall investigation. Specifically, work climate was associated with safety performance. The findings indicated that several work climate factors could function as leading indicators, implying that the work climate approach has been underestimated in safety research. Correlations with hydrocarbon leaks indicate that the organizational factors explored in this study can predict different levels of leaks. This suggests that the work climate approach used in this study represents an important contribution to achieving a holistic understanding of safety performance. Future research should replicate the study design in other settings and investigate the possibility of exploring relationships with other types of safety performance indicators using SWCI.

- Abstract
In this paper, we compare the performances of Singular Value Decomposition (SVD) and K-means clustering techniques in the optimization of fuzzy outputs towards the classification of epilepsy risk levels from EEG (Electroencephalogram) signals. The fuzzy techniques are applied as basic classifier to classify the risk levels of epilepsy on extracted parameters such as, energy, variance, peaks, sharp and spike waves, duration, events and covariance from the EEG signals. K-means clusters and SVD techniques are applied on the classified data to identify the optimized risk level (singleton) which characterizes the patient's state. The efficacies of these methods are compared with the bench mark parameters such as Performance Index (PI), and Quality Value (QV). A group of twenty patients with known epilepsy findings are analyzed. High PI such as 92.79% was obtained at QV's of 21.93 for K-means clustering optimization and PI value of 95.88 % was obtained at QV's of 22.43 in the SVD model when compared to the value of 40% and 6.25 through fuzzy classifier respectively. It was identified that the K-means clusters and SVD methods are good post classifiers in the optimization of epilepsy risk levels. [ABSTRACT FROM PUBLISHER]

In France, more than 4.8 million workers (25 % of employees) report they are exposed to biological agents. The biological risk is taken into account in several occupational sector but, in other ones, this risk remains unknown and poorly assessed. The lack of an evaluation of biological risk (EvBR) is partly due to a lack of knowledge of this risk, which is still poorly documented, but also to the absence of a standardised approach adapted to the assessment of biological risk. This work consisted of proposing a methodology to aid in the evaluation of biological risk (EvBR) for employers and prevention specialists allowing them to define an action plan in terms of prevention. To achieve this objective, we first carried out an inventory and an in-depth and critical analysis of existing approaches to EvBR. Next, work was carried out to identify the structure of the most appropriate methodology and to identify the risk descriptors that would allow the most exhaustive assessment possible. Finally, on the basis of these initial achievements, a methodology was designed, applied and validated in companies in an experimental sector, composting. Beyond the exploitation of bibliographical knowledge and the contribution of companies, the construction of this reference methodology requires new provisions: (i) the determination of biological agents within reservoirs, (ii) the creation of a classification based on Franco-German classifications accounting for 18,388 species, and (iii) the creation of a five-level hierarchy of hazards that integrates all hazards other than infectious ones. The methodology developed is operational and has been deployed in companies. The implementation of the reference methodology shows that it is more preventive than other approaches used in parallel and the exposure levels recorded in the Colchic database. The work carried out during the thesis therefore made it possible to design an EvBR methodology that allows employers to better estimate the risks to improve the working conditions of exposed employees. It also opens up necessary research and development prospects that will make it possible to improve its accuracy, particularly with regard to biodiversity and the dangerousness of biological agents, the measurement of exposures and, more broadly, epidemiological studies., En France, plus de 4,8 millions de travailleurs (25 % des salariés), se déclarent exposés à des agents biologiques. Dans certains secteurs professionnels, le risque biologique est pris en compte. Néanmoins, dans d’autres, ce risque biologique reste méconnu et mal évalué. Le défaut d’évaluation du risque biologique (EvRB) s’explique en partie par la méconnaissance de ce risque encore peu documenté, mais aussi par l’absence d’une démarche standardisée et adaptée à l’évaluation du risque biologique. Ces travaux ont consisté à proposer une méthodologie d’aide à l’évaluation du risque biologique à destination des employeurs leur permettant de définir un plan d’actions en matière de prévention. Pour atteindre cet objectif, nous avons d’abord effectué un recensement, et une analyse approfondie et critique des démarches existantes traitant de l’EvRB en milieu professionnel. Ensuite, un travail a été mené en vue de définir la structure d’une méthodologie la mieux appropriée et d’identifier les descripteurs de risque permettant de réaliser une évaluation la plus exhaustive possible. Enfin, une méthodologie a été conçue, appliquée et validée en entreprise dans un secteur d’activité expérimental, le compostage. Au-delà de l’exploitation des connaissances bibliographique et de la contribution des entreprises, la construction de cette méthodologie de référence a nécessité de nouvelles dispositions : (i) la détermination des agents biologiques au sein des réservoirs, (ii) la création d'une classification basée sur les classifications franco-allemandes comptabilisant 18 388 espèces, et (iii) la confection d’une hiérarchisation des dangers en cinq niveaux qui intègre tous les dangers autres qu’infectieux. La méthodologie développée est opérationnelle et a été déployée en entreprises. La mise en œuvre de la méthodologie de référence montre qu’elle est plus préventive que d’autres démarches utilisées en parallèle et que les niveaux d’exposition enregistrés dans la base Colchic. Le travail réalisé au cours de la thèse a permis de concevoir une méthodologie d’EvRB permettant aux employeurs de mieux estimer les risques en vue d’améliorer les conditions de travail des salariés exposés. Il ouvre aussi des perspectives de recherche et de développement qui permettront d’en améliorer sa justesse, concernant la biodiversité et la dangerosité des agents biologiques, la mesure des expositions et, plus largement, les études épidémiologiques.

The aim of this concept paper is the description of a new tool to support institutions in the implementation of targeted countermeasures, based on quantitative and multi-scale elements, for the fight and prevention of emergencies, such as the current COVID-19 pandemic. The tool is a cloud-based centralized system, a multi-user platform that relies on artificial intelligence (AI) algorithms for the processing of heterogeneous data, which can produce as an output the level of risk. The model includes a specific neural network which is first trained to learn the correlations between selected inputs, related to the case of interest: environmental variables (chemical&ndash, physical, such as meteorological), human activity (such as traffic and crowding), level of pollution (in particular the concentration of particulate matter) and epidemiological variables related to the evolution of the contagion. The tool realized in the first phase of the project will serve later both as a decision support system (DSS) with predictive capacity, when fed by the actual measured data, and as a simulation bench performing the tuning of certain input values, to identify which of them led to a decrease in the degree of risk. In this way, we aimed to design different scenarios to compare different restrictive strategies and the actual expected benefits, to adopt measures sized to the actual needs, adapted to the specific areas of analysis and useful for safeguarding human health, and we compared the economic and social impacts of the choices. Although ours is a concept paper, some preliminary analyses have been shown, and two different case studies are presented, whose results have highlighted a correlation between NO2, mobility and COVID-19 data. However, given the complexity of the virus diffusion mechanism, linked to air pollutants but also to many other factors, these preliminary studies confirmed the need, on the one hand, to carry out more in-depth analyses, and on the other, to use AI algorithms to capture the hidden relationships among the huge amounts of data to process.

El presente trabajo pretende analizar la prevalencia de la Hipoacusia Neurosensorial inducida por ruido en los trabajadores del Conjunto Residencial Campestre de La Dorada Caldas, que permitan recomendar medidas de mitigación. Se realizó un estudio de tipo descriptivo, transversal con enfoque mixto, en el cual se tuvieron en cuenta 14 trabajadores que laboran expuestos a ruido en el área de mantenimiento. Se utilizaron fuentes de información primaria haciendo uso de instrumentos específicos para la recolección de datos. Se diligenció un consentimiento informado, la historia audiológica ocupacional, se realizó la otoscopia y el examen de audiometría de Tonos puros. En el análisis de los resultados se pudo determinar que el 64% del total de los trabajadores presentaron hallazgos de alteración auditiva, de estos el 50% de grado leve y el 14% de grado moderado; 71% bilaterales y el 29% unilaterales. Las frecuencias más afectadas fueron 3000-4000-6000Hz. Por edad se presentó prevalencia entre los 35 y 50 años y por antigüedad en el cargo de 1 a 10 años. A pesar de que los hallazgos auditivos fueron significativos, para el caso específico de nuestra investigación, no es posible afirmar que estos se encuentren relacionados con HNIR, ya que no se cuentan con pruebas auditivas anteriores que permitan comparar y determinar que existe un cambio del umbral auditivo permanente, con respecto a una audiometría de base. El estudio suministra información relevante que puede ser utilizada por la Administración del Conjunto Campestre de La Dorada, para implementar dentro de su Sistema de Gestión de Seguridad y Salud en el Trabajo medidas preventivas y correctivas, que permitan intervenir el riesgo (ruido) y dar inicio al Programa de Vigilancia Epidemiológica para la Conservación Auditiva, que se ajuste a la normatividad vigente Colombiana y el cual tenga por objeto prevenir y detectar oportunamente lesiones auditivas inducidas por ruido en los trabajadores. The present work aims to analyze the prevalence of noise-induced Neurosensory Hearing Loss in workers of the La Dorada Caldas Rural Residential Complex, which will allow us to recommend mitigation measures. A descriptive, cross-sectional study was carried out with a mixed approach, in which 14 workers who work exposed to noise in the maintenance area were taken into account. Primary information sources were used making use of specific instruments for data collection. Informed consent, occupational audiological history, otoscopy and pure tone audiometry examination were performed. In the analysis of the results it was possible to determine that 64% of the total of the workers presented findings of auditory alteration, of these 50% of mild degree and 14% of moderate degree; 71% bilateral and 29% unilateral. The most affected frequencies were 3000-4000-6000Hz. By age there was prevalence between 35 and 50 years and by seniority in the position from 1 to 10 years. Despite the fact that the auditory findings were significant, for the specific case of our investigation, it is not possible to affirm that these are related to HNIR, since there are no previous hearing tests that allow comparing and determining that there is a change in the threshold permanent hearing, with respect to a baseline audiometry. The study provides relevant information that can be used by the Administration of the Rural Complex of La Dorada, to implement within its Occupational Health and Safety Management System preventive and corrective measures, which allow risk (noise) to be intervened and initiate to the Epidemiological Surveillance Program for Hearing Conservation, which complies with current Colombian regulations and which aims to prevent and detect noise-induced hearing injuries in workers in a timely manner.

Introduction: Patients with symptomatic heart failure (HF) require additive therapies and have a poor prognosis. However, patient characteristics and clinical outcome between HF patients treated in the outpatient setting vs. those who are hospitalized remain scarce. Methods and results: The BIOlogy Study to TAilored Treatment in Chronic Heart Failure (BIOSTAT‐CHF) included 2516 patients with symptoms and/or signs of HF: 1694 as inpatients and 822 as outpatients. Compared to ambulatory HF patients, inpatients had higher heart rate, urea, N‐terminal pro‐brain natriuretic peptide, lower blood pressure, lower estimated glomerular filtration rate, sodium, potassium, high‐density lipoprotein cholesterol, had more often peripheral oedema, diabetes, anaemia, and were less often treated with beta‐blockers and angiotensin‐converting enzyme inhibitors (ACEi). Outpatients had a more frequent history of HF hospitalization and received more frequently beta‐blockers and/or ACEi/angiotensin receptor blockers up‐titrated to target doses (P

Resumen El objetivo de la investigación es establecer la presencia de sintomatología psicológica clínica y subclínica, niveles de riesgo y necesidad de atención psicológica en el estudiantado de la Escuela de Psicología de la PUCESA que presenta bajo rendimiento académico. La investigación posee un diseño no experimental, de tipo cuantitativo, de alcance descriptivo y comparativo y de corte transversal. Participaron 92 estudiantes de las carreras de Psicología Clínica y Organizacional, divididos en 77,2% (mujeres) y 22,8% (hombres); evaluados con el Inventario de los 90 Síntomas revisado (SCL-90-R) de Derogatis, Rickels y Rock (1976). El 65,1% de los examinados presentaron bajo rendimiento académico (condicionamiento académico), mientras el 34,4% estuvo constituido por estudiantes no condicionados como grupo de comparación. Los resultados revelan que el estudiantado con primer condicionamiento muestra mayor prevalencia en ideas y comportamientos obsesivo-compulsivos, sintomatología depresiva, somatizaciones y en menor medida ansiedad, ideación paranoide y hostilidad; en el estudiantado con segundo condicionamiento los síntomas obsesivo-compulsivos disminuyen, la ansiedad casi desaparece, mientras que la depresión y la hostilidad aumentan, aunque sin alcanzar niveles clínicos; no existen diferencias significativas con el grupo control. Un 19,1% de los examinados se encuentra en riesgo debido a su sintomatología, mientras que un 3,5% presenta necesidades de atención psicológica. Abstract This study reports on clinical and subclinical psychological symptoms, risk levels and psychological care requirements identified in psychology majors with low academic achievement at the Catholic Pontifical University of Ecuador (PUCESA) This study is used a non-experimental design which is quantitative in nature, descriptive, comparative and cross-sectional. A sample group of 92 students were selected specifically among students majoring in Clinical and Organizational Psychology. The Revised Symptom Checklist – 90-R (SCL 90-R) by Derogatis, Rickels and Rock (1976) was used to assess the sample group of 77.2% women and 22.8% men. Approximately 65.1% of the participants displayed low academic performance (academic conditioned) while 34.4 made up the control group of students (unconditioned) for a head-to-head comparison. Based on the results, the first academic conditioned group had a higher prevalence of obsessive-compulsive ideation and behaviors with symptoms of depression, somatization, anxiety, paranoid ideation and hostility, though to a lesser extent. While students in the second non-condition group had fewer obsessive-compulsive symptoms and low anxiety, they had higher rates of depression and hostility which did not, however, attain clinical levels. Although no significant differences were found with the control group, 19.1% were deemed to be at risk for developing psychological disorders due to their symptoms, while 3.5% required psychological counseling.

The restrictions have been preferred by governments to reduce the spread of Covid-19 and to protect people's health according to regional risk levels. The risk levels of locations are determined due to threshold values based on the number of cases per 100,000 people without environmental variables. The purpose of our study is to apply unsupervised machine learning techniques to determine the cities with similar risk levels by using the number of cases and environmental parameters. Hierarchical, partitional, soft, and gray relational clustering algorithms were applied to different datasets created with weekly the number of cases, population densities, average ages, and air pollution levels. Comparisons of the clustering algorithms were performed by using internal validation indexes, and the most successful method was identified. In the study, it was revealed that the most successful method in clustering based on the number of cases is Gray Relational Clustering. The results show that using the environmental variables for restrictions requires more clusters than 4 for healthier decisions and Gray Relational Clustering gives stable results, unlike other algorithms.

This study focuses on occupational hazards and the determination of risk levels derived from them. Indoor climate, noise, and dust are examined. An approach with numerical criteria is offered to assess these occupational hazards in manufacturing using a simple/flexible risk assessment method. Practical examples and the results of measurements of occupational hazards in five industries (mechanical, printing, wood, plastic and clothing industries) in Estonia are presented. Noise, as the most obvious health hazard, is analysed in depth, and the risk for noise‐induced hearing loss is estimated. The overall purpose of the paper is to draw attention to the importance of measurements of occupational hazards in industry and to act as a reminder of a number of issues of practical relevance to effective workplace risk assessment from which employees, employers, occupational hygienists and physicians as well as authorities can benefit today and in the future.

This paper proposes a practical method for dynamic maintenance planning based on Dynamic Risk Assessment (DRA). This is founded on the interpretation, in terms of risk levels evolution, the available information of monitoring events and maintenance activities integrated in and that conform the condition-based maintenance (CBM) processes. DRA proposal is supported by ISO 31000 risk management framework in order to better understanding and results integration within other risk management approaches. Proposed method analyzes CBM results (monitoring events and maintenance activities) regarding their impact on failure risk level, and how to program and manage maintenance decision making (maintenance planning) regarding with dynamic risk evolution. This strategy not only helps maintenance management optimization but also facilitates the link of intelligent maintenance with global risk management within the organization, which is lined with modern Asset Management principles. To illustrate the method, an example of a real use case is presented where it is applied to the dynamic maintenance planning of a critical component in a high-speed train, and which integrates monitoring, predictive analytics and inspection data. • Build the planning proposal as a DRA tool. • Connect the results of monitoring and prognosis. • Control the status of the failure modes. • The ease of scheduling maintenance actions. • For the operator, the information to compose the level of risk is transparent.
