Abstract
Introduction: The quality
of work life is one of the main issues in human resource management that is
related to job satisfaction, resignation, turnover rate, personality and job
stress. The present study was conducted to investigate the quality of working
life in relation to stress levels and participation in health care workers in
cities.
Materials and
Methods: The present cross-sectional study was conducted on 124 random health care
workers employed in centers across the city of Hamadan. Walton's quality of
work life questionnaire, Belcher's participation questionnaire and a stress
questionnaire were used for achieving the study objectives. The Pearson test
was used for determining the correlation between the variables.
Results: The results
showed that 40.3% of the subjects reported their overall participation rate to
be low, 38.7%% reported it to be moderate and 21% reported it to be high. In
addition, 73.4% of the subjects reported low levels of perceived stress and
26.6% reported it to be very high. The findings of the study showed a significant
positive correlation between participation and the quality of work life (r=0.33
and p<0.001). The quality of work life and stress were also
found to have a negative correlation (p=0.015 and r=-0.219).
Conclusion: Through
understanding participation and levels of stress among the employees and
through presenting and implementing appropriate strategies for reducing stress
and encouraging participation, the quality of work life and ultimately the
productivity of health care organizations can be increased.

Abstract
Introduction: the quality of life of nurses and nurse aides is under the influence of various factors including the occupational ones, which affect the quality of their services. The purpose of this research was to investigate the occupational and demographic factors effective on the quality of life of nurses and nurse aides working in teaching hospitals affiliated to Kerman University of Medical Sciences.
Methods: the present research was a cross-sectional one conducted in 2014 on 620 nurses and nurse aides. Simple random sampling method was utilized. The data were collected via the World Health Organization Quality of Life short form (questionnaire). Shift working, having a second job, marital status, length of marriage and having a shift working spouse were the independent variables of this study. Data were analyzed in SPSS 18 software using analysis of variance (ANOVA), Pearson’s correlation coefficient, independent t and linear regression statistical tests.
Results: the average age, length of marriage and work experience in hospital were 32.81 ± 7.84, 10.61 ± 7.30 and 10.29 ± 7.68, respectively. The number of children, having a second job, satisfaction from the hours spent with family, and belief in the effect of night work on family life were factors effective on quality of life (P > 0.05). The highest relationship of quality of life was with environmental health (r = 0.87, P = 0.001) and the lowest was with social health (r = 0.75, P = 0.002).
Conclusions: Avoiding to have a second job, scientific planning of shift work schedules and trainings relevant to life skills in shift workers would help improve the quality of life of nurses and nurse aides.

Abstract
Introduction: Work-related fatigue is a source of concern, even in most industrialized countries. One of the most important factors influencing an employee’s physical and mental condition is the degree to which employees are able to recover from fatigue and stress after work. Factors such as workload can cause fatigue in workers. The aim of this study was using the need for recovery scale to assess workload in mine workers and its relationship with demographics.
Methods: In this cross-sectional study, 80 workers of a mine were surveyed. The data gathering tools used in this study were demographic characteristics questionnaire and the need for recovery scale. The scale assesses the workers workload with 11 two-optioned phrases. Mean, standard deviation, and Pearson’s correlation coefficient and ANOVA tests were used in order for data analysis.
Results: Mean (SD) score of the need for recovery scale was 55.22 (23.93), indicating moderately high workload in the workers. A total of 58.7% of workers experienced high levels of workload. Among the demographics, only body weight had a significant relationship with the need for recovery score (P value = 0.043).
Conclusions: Due to the relatively high need for recovery in the study population, solutions should be employed, such as reducing the workload, use of work-rest schedules, performing heavy tasks within teams, and providing conditions for proper and enough recovery after work, which can increase health conditions of workers.

Abstract
Introduction: Regular physical activity plays an important role in the prevention of low back pain, osteoporosis, cardiovascular disease, obesity, diabetes, cancer, hypertension, depression and early death. Also, work ability is related to the interactions between physical and mental ability, working conditions, employee efficiency, and employee health status. In this research, the relationship between work ability and the level of physical activity is investigated.
Materials & Methods: This study was descriptive-analytical and cross-sectional, which was conducted among 120 office workers and operatives. Physical activity and work ability index were measured using physical activity questionnaire and Iranian version of work ability index. Data analysis was performed using SPSS20 and (P <0.05) was considered significant.
Results: In this study, gardeners and office workers respectively,had the highest and lowest levels of physical activity with the mean of 4206.09 and 3567.58. However, work ability almost was the same in all groups. Also, Pearson correlation coefficient showed that there was no significant relationship between work ability index and physical activity.
Conclusion: According to the results,the work ability index of subjects was good and physical activity was high. Also, there was no significant relationship between work ability index and physical activity, thus making plans to promote the work ability index should be a priority in the intervention program.

Abstract
Background and Objectives: Increasing the retention of health care workers in the context of Covid-19 expansion is one of the most important challenges for the health care systems. To design a strategy to maintain health care workers, it is necessary to identify the factors influencing willingness to work or leave the job among health care workers. This study aimed to identify the factors affecting the willingness to work or leave the job among health care workers during the Covid-19 pandemic.
Methods: To identify relevant publications, the online Databases including Scopus, PubMed, Web of Science, and ProQuest were searched on October 20, 2020. Based on the inclusion criteria, only studies that investigated the factors influencing willingness to work or motivation to leave the job among health care workers during the Covid-19 pandemic were included.
Results: Of the 610 studies found through searching, after deleting similar and unrelated studies, a number of 10 cross-sectional articles with a sample size of 15834 subjects were selected. Obtained findings indicated that the willingness to work among health care workers ranged from 61% to 98.7% and averaged 83.5%. The results of studies showed that job factors such as work experience, previous work experience in emergency time or Covid-19, workload, cooperation between employees, the relationship between employees and managers, access to personal protective equipment, and welfare facilities were significantly proportional to the willingness of health care workers to work.
Conclusion: The results of this study showed to design a strategy to maintain the health care workers during the Covid-19 pandemic, a broad range of occupational and psychological variables should be considered. Due to the limited number and quality of studies and the extent of influential variables, more studies are needed in this field.

Abstract
Objectives: Psychological load, such as workload, not only disrupts work performance but can also directly affect employee safety leadin to accidents. However, despite this issue, not much effort has been made to develop an assessment tool to measure the psychological burden related to the occupational safety and health of employees. Therefore, the present study was designed to validate the psychological burden scale of workers by Kim et al. (2018) from the perspective of occupational health and safety.
Methods: The statistical population of the research consisted of all the workers employed in the Eastern Alborz Company of Shahroud city, and 349 workers participated in the research using a simple random sampling method. In the present study, the mental load scale by Kim et al. (2018), the Copenhagen psychosocial scale (COPSOQ), and the occupational stress scale (HSE) were used. The data were analyzed using Pearson's correlation coefficient tests and confirmatory factor analysis using SPSS version 22 statistical software and Lisrel version 8.5.
Results: The results showed that all the components of workers' psychological burden including the overall score and the psychosocial scale and occupational stress scale have a positive and significant relationship. The results of the confirmatory factor analysis also indicated a good fit of the model in determining the factors in the initial form as proposed by Kim et al. (2018). To determine the reliability of the scale, the value of Pearson's correlation coefficient was obtained at 0.82 in the test and retest phases. Additionally, the results of this study showed that 26.1 percent of workers experienced low psychological burden, 49.6 percent experienced moderate psychological burden, and 24.4 percent experienced severe psychological burden.
Conclusion: Based on the results of the current research, the workers' mental burden scale (Kim et al., 2018) is a valid and reliable tool that can be used to evaluate the psychological burden of workers in research and intervention studies.

Abstract
Objectives: Cargo workers at Ahvaz Airport in Ahvaz, Iran are at risk of musculoskeletal disorders. In this regard, the present study aimed to investigate their carrying out tasks and postures.
Methods: In this descriptive-analytical study, the census method was used to select 21 cargo workers in Ahvaz Airport. Task analysis was carried out by Hierarchical Task Analysis (HTA) and Quick Exposure Check (QEC). Moreover, the Manual Handling Assessment Charts were used to evaluate the manual load. The tools employed in this study included observation, photography, and a Cornell Musculoskeletal Disorder Questionnaire (CMQD) questionnaire. Statistical calculations were performed in SPSS (version 16) and Spearman's correlation coefficient for the variables.
Results: Each of the cargo workers of Ahvaz airport moves an average of 400 bags per shift. Spearman's correlation coefficient showed a significant relationship between musculoskeletal disorders and the variables of age, height, and Body Mass Index with values of 0.002, 0.005, and 0.003, respectively. The QEC method was used to observe the worst postures with a numerical score between 50 and 70, which were related to the standing posture at the flat roller and the sitting posture in the aircraft cargo. The examination of the CMQD questionnaire revealed that 61.6%, 65%, and 62% of diseases were related to shoulder, arm, and back, respectively.
Conclusion: After job analysis by the HTA method and evaluation of the results through the QEC method, it was determined that loading and arranging luggage in the cart and cargo were the most risky tasks. Both the MAC and QEC methods also indicated the necessity of an immediate change in the process of moving luggage.

Abstract
Objectives: Various causal pathways play a role in the occurrence of depression in healthcare workers. This study aimed to assess the effect of perceived stress and insomnia on depression in healthcare workers using path analysis in Hamadan, Iran.
Methods: In this cross-sectional study, healthcare workers from Shahid Beheshti and Sina hospitals in Hamedan in 2023 were recruited. Perceived stress with two subscales of perceived helplessness and perceived self-efficacy, as well as insomnia and depression, were investigated using validated questionnaires. The path analysis was applied to assess the association.
Results: In total, 235 healthcare workers (35.7% nurses) were included. Gender, age, monthly working hours, and number of night shifts per month had a significant impact on depression (P<0.05). Path analysis demonstrated that except for the effect of perceived self-efficacy on insomnia, all standardized regression weights for relationships were statistically significant (P<0.05). The effect size of perceived helplessness on depression was the strongest compared to other relationships (standardized regression weight = 0.40). The direct effect of perceived helplessness and perceived self-efficacy on depression or insomnia as a mediator had a good fit to the data.
Conclusion: As evidenced by the obtained results, with the implementation of intervention and preventive programs to reduce stress and improve sleep, the occurrence of depression in healthcare workers is expected to decrease significantly.

Abstract
Objectives: The primary aim of this study is to examine the impact of carbon dioxide concentrations in the air on thermal comfort, cognitive performance, and heart rate among healthcare workers while they engage in their duties within therapeutic environments. These settings are often characterized by high occupancy, inadequate ventilation, underground locations, limited natural light, and exposure to pollutants.
Methodology: In this laboratory-based research, 20 employees from a specialized clinic were randomly assigned into two groups of ten. They were exposed to varying levels of carbon dioxide at a controlled temperature of 25 degrees Celsius: one group experienced 1100 ppm with adequate ventilation, while the other was subjected to 1800 ppm without ventilation. Key parameters such as heart rate, thermal comfort (assessed using the ASHRAE standard questionnaire), and cognitive performance (measured through the MOCA test) were recorded. The collected data were analyzed using multivariate analysis of covariance (MANCOVA).
Results: The statistical analysis revealed significant effects of cognitive performance and carbon dioxide levels (1800 ppm vs. 1100 ppm) on thermal comfort (F(1,15)=13.257, p<0.05 and F(1,15)=16.694, p<0.05). Furthermore, both the carbon dioxide levels and the gender of participants significantly influenced the heart rate of healthcare workers in their work environments (F(1,15)=53.381, P<0.05 and F(1,15)=9.642, p<0.05). Specifically, individuals exposed to 1800 ppm of carbon dioxide reported a thermal dissatisfaction score that was 0.878 units higher and exhibited a heart rate that was 9.25 beats per minute greater compared to those exposed to 1100 ppm..
Conclusion: The findings underscore the importance of continuous air quality monitoring in workplace settings. Such measures can enhance thermal comfort levels, improve cognitive performance, and mitigate health risks for healthcare workers engaged in their professional activities.
