This paper examines the eigenvalues and eigenvectors of a massive rigid square block bonded to an elastic medium. Uncoupled vertical and coupled sliding-rocking modes of vibration are considered. The supporting medium is modeled as an elastic homogeneous or layered, inertial or massless half-space. For a geometrically damped system, the eigenvalues .are complex-valued, while they are purely imaginary in an un-damped system. Numerical results are presented to illustrate the effects of inertial interaction. The data is computed by a procedure that takes into account the mixed boundary conditions at the surface of the half-space.

In this paper a numerical model for the minimum-weight design of a rectangular machine foundation under a harmonic vertical load is presented. The analysis of the dynamics of foundation-soil interaction is based on frequency-dependent dynamic properties of a semi-infinite supporting medium and includes the shape of the foundation plan, the embedment of the foundation into the soil, and hysteretic material damping of the soil. Dimensions of the concrete block are assumed as design variables. Constraints are placed on resonant frequency, vertical displacement amplitude, stresses in the soil and dimensions of the foundation concrete block. A sequential programming method with variable move limits is used to obtain the optimal solution, which is affected by inertia properties of the machine-foundation-soil system, damping from dynamic soil-foundation interaction and local soil conditions. Numerical examples are given to demonstrate the applications of the proposed approach.

Purpose: The aim of the research was to investigate correlation between strain on the spine, work place and years spent in work. Material and methods: Research was carried out on a group of 937 nurses working in health care units in the Warsaw district area. The study was conducted using the method of diagnostic survey and as a research tool a questionnaire sheet including 70 questions divided into 6 categories was used. Research was carried out voluntarily and anonymously. Results: The case study confirmed earlier hypotheses that strain on skeleton and muscles, non psychological and constrained body positions in relation to years worked in profession have significantly statistical correlation on a level of 0.005, χ² =16.768. Strain on the spine is also dependent upon ward in which nurses work and upon characteristic of executed work. 79% of tested people fears of degenerative changes of the spinal column. Health problems that are connected to lower back pain are reported by 61% of nurses. 67% of ward nurses and 79% of scrub nurses, more often than departmental nurses and these working in other basic and specialised units, complain about pain symptoms after duty. The greatest strain placed on the spine affects tested nurses working in gastrology department (74%), department of internal medicine and neurology department (70%). Conclusion: Strain on the spine is a serious issue as it creates a vast number of health problems which results in decreasing the work quality. [ABSTRACT FROM AUTHOR]

Tekst przedstawia spojrzenie na nową rolę kar i środków karnych, których celem nie jest pozbawianie wolności skazanych, ze szczególnym uwzględnieniem środków o charakterze majątkowym. Autorka opracowania stara się odpowiedzieć na pytanie, czy akceptacja politycznokryminalnych założeń kodeksu karnego i wprowadzenie i stosowanie środków o charakterze majątkowym nie stoi w sprzeczności z założeniami poprzedniego represyjnego modelu karnego. W tym celu Z. Sienkiewicz dokonuje szczegółowej i pogłębionej charakterystyki poszczególnych środków o charakterze majątkowym takich jak grzywna odgrywająca największą rolę w zwalczaniu drobnej przestępczości. Obok nich w artykule znajduje się analiza środków takich jak: przepadek korzyści majątkowej, obowiązek naprawienia szkody, nawiązka, przepadek przedmiotów czy konfiskata mienia. Autorka opracowania zwraca również uwagę odbiorców na problem nadmiernej kumulacji w wymierzaniu środków karnych o charakterze majątkowym przed nowelizacją kodeksu karnego w 1997 r. W swojej charakterystyce Z. Sienkiewicz podkreśla znaczenie wprowadzenia nowego środka karnego wobec sprawcy, jakim było świadczenie pieniężne. W tekście wymienione zostały również sytuacje, w ramach których stosowanie środków o charakterze majątkowym ma charakter obligatoryjny jak w przypadku czynów o charakterze chuligańskim czy też w ramach obowiązków probacyjnych. Na zakończenie autorka podkreśla, że przepisy kodeksu karnego stanowią tylko punkt wyjścia do praktycznego stosowania ich przez sądy. Według niej niezwykle ważna w tym zakresie jest praktyczna możliwości oceny stanu majątkowego sprawców a tym samym racjonalne stosowanie środków o charakterze majątkowym.

Abstract Background Epidemiological evidence showing a consistent association between the risk of childhood leukaemia and exposure to power frequency magnetic fields has been accumulating. This debate considers the additional precautionary intervention needed to manage this risk, when it exceeds the protection afforded by the exposure guidelines as recommended by the International Commission on Non-Ionizing Radiation Protection. Methods The Bradford-Hill Criteria are guidelines for evaluating the scientific evidence that low frequency magnetic fields cause childhood leukaemia. The criteria are used for assessing the strength of scientific evidence and here have been applied to considering the strength of evidence that exposures to extremely low frequency magnetic fields may increase the risk of childhood leukaemia. The applicability of precaution is considered using the risk management framework outlined in a European Commission (EC) communication on the Precautionary Principle. That communication advises that measures should be proportionate, non-discriminatory, consistent with similar measures already taken, based on an examination of the benefits and costs of action and inaction, and subject to review in the light of new scientific findings. Results The main evidence for a risk is an epidemiological association observed in several studies and meta-analyses; however, the number of highly exposed children is small and the association could be due to a combination of selection bias, confounding and chance. Corroborating experimental evidence is limited insofar as there is no clear indication of harm at the field levels implicated; however, the aetiology of childhood leukaemia is poorly understood. Taking a precautionary approach suggests that low-cost intervention to reduce exposure is appropriate. This assumes that if the risk is real, its impact is likely to be small. It also recognises the consequential cost of any major intervention. The recommendation is controversial in that other interpretations of the data are possible, and low-cost intervention may not fully alleviate the risk. Conclusions The debate shows how the EC risk management framework can be used to apply the Precautionary Principle to small and uncertain public health risks. However, despite the need for evidence-based policy making, many of the decisions remain value driven and therefore subjective.

Background: Based on its definition of an individual's quality of life, the World Health Organization identified the following six basic domains of this concept: physical domain, psychological domain, level of independence, social relationships, environment and spirituality. The aim of the study was to examine these quality of life dimensions in pre-older and older adults in relation to selected sociodemographic variables., Methods: The study included 2,040 adults aged 55 or older. It was conducted using a diagnostic survey by means of a questionnaire with sociodemographic questions and the EQ-5D-3L descriptive system., Results: The vast majority of male and female respondents reported no problems in most EQ-5D-3L dimensions. However, the mean EQ-5D-3L index score indicated a slight difference in scores between men and women. A statistically significant difference between male and female respondents in individual dimension scores was found only for the usual activities dimension. The proportion of respondents reporting no problems decreased with age in most dimensions, except for anxiety/depression. Age was statistically significantly correlated with all individual dimension scores and the index score. The vast majority of respondents across all education levels reported no problems in most dimensions. Education was statistically significantly correlated with all individual dimension scores and the index score., Conclusion: The vast majority of respondents across both sexes and all education levels reported no problems in most EQ-5D-3L dimensions. The proportion of respondents reporting no problems decreased with age in most EQ-5D-3L dimensions. Systematic research on dimensions of health-related quality of life will help design measures for healthy and successful ageing., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Głowacka, Sienkiewicz, Dykowska and Haor.)

In 2020 it is estimated that 281 million people were international migrants. Migrants constitute a potentially vulnerable population in terms of facing discrimination, poor living and housing conditions, and insufficient access to healthcare services. Due to the armed conflict in Ukraine in 2022, almost 10 million people crossed the Polish border within a year of the outbreak of the conflict. The objective of this paper is to present the use of primary healthcare services by people migrating from Ukraine to Poland and identify the barriers in access to healthcare by this group of persons. This study used a qualitative research technique in the form of an expert interview using individual in-depth interviews (IDI). The study group consisted of professionally active primary healthcare providers (doctors, nurses, and facility managers) in Poland. Research was carried out in the areas regarding the availability of healthcare, the potential threats and challenges, and possible system solutions. The results showed that the most common cause for doctor's appointments among migrants are respiratory infections, including COVID-19. Many cases were related to back pain, mainly resulting from the physical work of the patients. Additionally, some barriers to access and the provision of healthcare services for patients from Ukraine were identified. The majority (75%) of respondents indicated language as a significant barrier when providing services. Based on the study results, we recommend creating a dedicated website and telephone hotline for this group of persons as well as the use of traditional media to distribute information about access to healthcare services. It is also essential to focus on assistance for older people, since they may experience more difficulties with language and navigating the healthcare system.

The objective of the study was to determine the degree of adherence to pharmacological treatment in people in pre-older adults and older adults age groups and to analyse the correlation between selected sociodemographic parameters, severity of anxiety as a trait, symptoms of depression, a sense of family support and satisfaction with life, and adherence in people over 55 years of age. The study was conducted in a group of 2,040 people (1,406 women, 634 men) aged 55 to 100 (the average age was 65.4). The following sociodemographic variables were analysed: age, gender, education. The following scales were used: State-Trait Anxiety Inventory (STAI), Beck Depression Inventory (BDI), Satisfaction With Life Scale (SWLS) and the Multidimensional Scale of Perceived Social Support (MSPSS). The Adherence in Chronic Diseases Scale (ACDS) was used to test adherence, understood as the implementation of the therapeutic plan. The results obtained in the ACDS ranged from 6 to 28 points; the median was 24 points (21-28). The multiple coefficients of determination (multiple R 2  = 0.11; p  < 0.001) indicated an explanation of approximately 11% of the value of the ACDS dependent variable. The total correlation of all variables (multiple R ) with the ACDS general variable in the mean correlation was 0.33. Independent factors affecting adherence assessed in the ACDS were: severity of anxiety as a trait ( p  = -0.21 ± 0.03; p  < 0.001), family support ( p  = 0.10 ± 0.04; p  = 0.029), severity of depression symptoms ( p  = -0.08 ± 0.03; p  = 0.005), age of respondents ( p  = 0.07 ± 0.02; p  = 0.003) and satisfaction with life ( p  = 0.06 ± 0 0.03; p  = 0.027). Severity of anxiety as a trait, age, severity of depressive symptoms, a sense of satisfaction with life and family support are important factors affecting adherence., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Głowacka, Polak-Szabela, Sienkiewicz and Kornatowski.)

Objectives: Endometriosis is a disease that involves the ectopic growth of the endometrial tissue outside the uterine cavity. Its average occurrence is about 10% of women of reproductive age. Making a diagnosis of the disease is commonly long-lasting and ambiguous due to the wide variety and intensity of symptoms. The aim of the study is to determine factors affecting the quality of life of women struggling with endometriosis., Material and Methods: A cross-sectional study was conducted using a diagnostic survey method with the use of the author's questionnaire and the WHOQOL-BREF questionnaire. The study population included 650 people (group with endometriosis - 361 women and group without endometriosis - 289 women)., Results: In the group of women with endometriosis, the mean age was significantly higher (31.87 vs 24.99). Difficulties with conception were significantly more common (51.67%) in the endometriosis group compared to 5.52% in the non-endometriosis group. In each area, the quality of life of women with endometriosis was significantly lower (p = 0.000). Women with the history of the disease of over 3 years significantly more often complained of dyspareunia (p = 0.048), bladder pain (p = 0.01) and lower back pain (p = 0.029)., Conclusions: Endometriosis significantly reduces women's quality of life. Factors that deteriorate the quality of life of women with endometriosis include severe pain, infertility, dyspareunia and reduced satisfaction in various spheres of life (somatic, mental, social). More research is necessary to improve the quality of life of women with endometriosis.

Background: Job satisfaction is one of the key factors related to the work efficiency of nursing staff. Its level may affect the degree of the professional's commitment to work and effectiveness in performing their professional tasks. For a modern organisation, job satisfaction is associated with a number of benefits for both the employee and the employer. Job satisfaction of nurses is extremely important due to their professional tasks being related to the care of patients. Nurses with low levels of job satisfaction may have less capabilities to provide high quality care and thus maintain a high level of patient satisfaction., Material and Methods: This was a cross-sectional observational study which included 302 people practising the profession of a nurse and employed in a hospital during the COVID-19 pandemic. The level of job satisfaction was assessed using the Minnesota Satisfaction Questionnaire (MSQ), which was preceded by questions characterising the research group. The questionnaire was delivered to the respondents in electronic form., Results: The respondents obtained an average result in terms of the level of job satisfaction (M±SD 58.53±11.42). The highest rated area was the chance to do something good for other people (M±SD 3.85±0.87), and the lowest rated areas included: the method of work evaluation and the remuneration system (M±SD 2.24±0.74), the chances for advancement (M±SD 2.38±0.94) and the chance to take up senior positions (M±SD 2.39±0.88) as well as the number of tasks to be performed during the working day (M±SD 2.40±0.86)., Conclusions: In this study, average values of the level of job satisfaction were obtained. A higher level of job satisfaction was shown by those employed in a non-infectious hospital and those with higher monthly earnings. Employers' policy should focus on improving working conditions, the remuneration system and promotion opportunities.

Parental perspective on the health, safety, and quality of life in children and adolescents with cystic fibrosis (CF)., Aim of the Study: Assessment of the impact of a chronic disease such as cystic fibrosis (CF) on the quality of life and safety of children and adolescents as perceived by parents/caretakers., Methods: The study was conducted at the Department of Lung Diseases of the Institute of Mother and Child, a branch of the Cystic Fibrosis Centre Children of Warsaw SZPZOZ in Dziekanów Leśny, the largest pediatric CF center in Poland, and in the Rodzinamuko group on Facebook. A total of 139 parents participated in the study. The study was conducted using the diagnostic survey method with the use of the Kid- & Kiddo-KINDLR questionnaire for examining the quality of life of children and adolescents and a demographic questionnaire., Results: The perception of cystic fibrosis (CF) as a chronic disease varies based on parental residence and professional status. The well-being of children and adolescents with CF is tied to their parents' employment, particularly regarding schooling. Social interactions are influenced by the level of parental education. The quality of life in children and adolescents with CF is age-dependent, with younger children exhibiting higher quality of life. This age-quality of life relationship extends to physical well-being, emotional well-being, and school-related aspects. Furthermore, the emotional dimension of quality of life is affected by the child's age at the time of diagnosis., Conclusions: The Kid- & Kiddo-KINDLR QoL Questionnaire for children with cystic fibrosis is a good tool to measure parental knowledge. The study shows the need for the whole family to understand and be aware of the impact of CF on family life. Parents may be tired or may misunderstand or miscommunicate the medical team's instructions, which may affect both family life and patient safety. To ensure patient safety, parents should work with healthcare professionals at hospitals or clinics but also at home. They should also account for the family as a whole, not just for the problems of the child with CF.

Background: Social support has a vital role in preventing traumatic stress in nurses. Nurses are regularly exposed to contact with violence, suffering, and death. The situation worsened during the pandemic because they were also faced with the possibility of infection SARS-CoV-2 and death from COVID-19. Many nurses are faced with increased pressure, stress, and other adverse effects on their mental health. The study aimed to measure the relationship between compassion fatigue and perceived social support in polish nurses., Methods: The study was conducted on 862 professionally active nurses in Poland using the CAWI method (Computer-Assisted Web Interview). The professional Quality of Life scale (ProQOL) and the Multidimensional Scale of Perceived Social Support (MSPSS) were used for collecting the data. StatSoft, Inc. (2014) was used for data analysis. For comparisons between the groups: Mann-Whitney U test, ANOVA Kruskal-Wallis test, and multiple comparisons (post-hoc). The relationships between variables were tested using Spearman's rho, Tau Kendall, and the chi-square test., Results: The research showed the presence of compassion satisfaction, compassion fatigue, and burnout in the group of Polish hospital nurses. A higher level of perceived social support was associated with lower compassion fatigue (r = -0.35; p < 0.001). A higher level of social support was associated with higher job satisfaction (r = 0.40; p < 0.001). The study also found that a higher level of social support was associated with a lower risk of burnout (r = -0.41; p < 0.001)., Conclusions: Preventing compassion fatigue and burnout should be a priority for healthcare managers. Notably, an essential predictor of compassion fatigue is that Polish nurses often work overtime. It is necessary to pay more attention to the crucial role of social support in preventing compassion fatigue and burnout.

In the face of the current COVID-19 pandemic crisis, healthcare professionals, including nurses who provide direct care for patients, are at particular risk of mental health problems. The aim of the study was to evaluate the prevalence of symptoms of depression, anxiety, and stress among nurses working in healthcare facilities during the COVID-19 pandemic., Materials and Methods: This was a cross-sectional observational study. A total of 333 professionally active nurses participated in the study. Data was collected in the period from 10 November to 20 November 2021. We collected sociodemographic data and used the short form of Depression Anxiety Stress Scale (DASS-21) to assess the mental health among nurses., Results: Severe and very severe symptoms of depression were found in 23.1% of nurses, whereas moderate symptoms were detected in 30.3%. High to very high levels of anxiety were observed in 46.5% of respondents, while 25.8% of nurses showed a moderate level of anxiety. Moderate and high levels of stress were found in 35.4% and 14.1% of the respondents, respectively. Contact with a patient suspected of having SARS-CoV-2 infection was a significant predictor of depressive symptoms. Gender, workplace, and contact with patients suspected of SARS-CoV-2 infection and patients with COVID-19 were significant predictors of anxiety, whereas contact with patients suspected of being infected with SARS-CoV-2 and COVID-19 patients was a significant predictor of stress., Conclusions: High scores for depressive symptoms, anxiety, and stress among Polish nurses during the fourth wave of the COVID-19 pandemic are indicative of a direct threat to the mental health of nurses. Targeted support strategies need to be developed and implemented to prevent the deterioration of mental health in this group.

Background: The unexpected changes caused by the COVID-19 pandemic related to the fear of developing the disease, and the need for social distancing and isolation have had an effect on people's mental health. These drastic changes can result in the development of anxiety, depressive symptoms and sense of loneliness. Elderly and chronically ill individuals are at a particularly high risk of developing COVID-19, suffering severe illness and dying as a result of it., Aim of the Study: The aim of the study was to assess the prevalence of anxiety, depressive symptoms, irritability and loneliness in the elderly aged 60 years and older as a group exposed to the negative impact of the COVID-19 pandemic, and to analyze the relationships between loneliness and mental health of the respondents and sociodemographic variables and chronic diseases., Materials and Methods: The study was conducted in Poland among 221 individuals aged 60+. The study material was collected using a sociodemographic questionnaire, Hospital Anxiety and Depression Scale (HADS-M) and a revised University of California Los Angeles loneliness scale (R-UCLA). Women accounted for 47.51% and men for 52.49% of study participants; the mean age was 65.18 (SD = 4.06)., Results: In total, according to HADS-M, depressive symptoms were present in 19.15% of the participants and borderline states in 14.18% of them. Based on R-UCLA, moderate and moderately high sense of loneliness was present in 58.83% of the participants. Sense of loneliness was significantly correlated with the prevalence of depressive symptoms (p < 0.001)., Conclusions: In this study, one in five participants experienced anxiety and depressive symptoms. Two out of three participants experienced a moderate sense of loneliness. Individuals who displayed a higher level of loneliness also had a higher severity of anxiety level depressive symptoms and irritability. Elderly individuals should be under special care due to their high risk of experiencing physical and mental effects of the COVID-19 pandemic., (© 2021. The Author(s).)

Aim: The purpose of this study is a comparative analysis of the degree of disease acceptance and social support in patients with peripheral vascular diseases and other medical conditions treated in surgery ward., Design: A cross-sectional study., Methods: This cross-sectional study compares disease acceptance and social support in a group of 212 patients with peripheral vascular diseases and other conditions treated in surgery ward. A standardized Acceptance of Illness Scale (AIS) and Social Support Scale were used to collect the research data., Results: Overall, on the AIS, 14% of patients with surgical diseases and 34% of patients with vascular diseases had a low disease acceptance rate. A high level of support was demonstrated in 41% of study participants with surgically treated diseases and in 17% of participants with vascular diseases., (© 2021 The Authors.
