Abstract
Introduction: As
a healthcare providing establishment, hospitals can be affected by sources of
noise pollution which then impose negative effects on the health and comfort of
patients and personnel. The present study was conducted to determine the
relationship between sound annoyance and general health in the personnel of
university affiliated and non-university affiliated hospitals in Shiraz.
Materials and Methods: The present descriptive analytical study was conducted in four university affiliated
and non-university affiliated hospitals in Shiraz with a sample size of 300
using a predetermined equation and according to the results of previous
studies. The instruments used in the study included the General Health
Questionnaire (GHQ), the Noise Annoyance Scale (NAS) and an audiometer (CEL-440
model).
Findings: The present study
found a small inverse relationship between the total general health score in
the hospital personnel and the sound pressure level at university-affiliated
hospitals (r=-0.103) and a direct positive relationship at non-university
affiliated hospitals (r=0.274), which were not statistically significant
(P≤0.05). The relationship of somatic symptoms, anxiety, insomnia, social
dysfunction and depression to sound pressure was inverse and small (r=-0.195
and P≥0.05). However, there was a direct positive relationship between general
health and sound annoyance (r=0.266 and P≤0.05).Conclusion: According
to the results obtained, noise levels are higher than the acceptable exposure
limit in university-affiliated hospitals, which affect both the patients' and
the personnel's general health, necessitating the adoption of control measures.

Abstract
Objectives: Considering the importance of employees' behavior in service organizations and its significant impact on their success and failure, the present study investigates the environmental and ergonomic factors affecting the mental health and behavior of employees in one of the branches of Islamic Azad University.
Methods: The present study is applied in terms of purpose and descriptive-correlational in terms of data gathering and analysis. The statistical population of the study includes: 315 employees of Rasht Branch of Azad University, out of them 196 people were selected by random sampling method and the necessary data were collected using a questionnaire. Structural equation modeling and SMART PLS3 software were used to test the hypotheses.
Results: According to the findings, workplace layout affects on use of work equipment (0.389), use of office chair (0.252) and environmental conditions (0.538), but the effect of workplace layout on the posture of employees was not confirmed in 5 percent significance level. Also, the effect of posture (0.586), layout (0.440), work equipment (0.458), office chair (0.345) and environmental conditions (0.550) on public health and also the effect of general health (0.690) and environmental conditions (0.158) on employees’ behavior is significant. Examining the indirect relationships of the research model also shows that workplace layout affects employee behavior through the general health and environmental conditions. Workplace layout influences employees’ behavior through work equipment, office chair, environment conditions and general health.
Conclusion: The indirect effect of workplace layout on employees’ behavior through public health has the highest impact (0.304), therefore, making policies for the general health, can improve employees’ behavior.

Abstract
Objectives: Nurses are at the front line of treatment and coping with COVID-19 pandemic. Therefore, the present study investigates the pandemic’s impact on nurses ’mental workload and determines its predictive factors.
Methods: This descriptive-analytical study was done on 234 nurses in two groups working at COVID-19 and non-COVID-19 wards in 2020. The criteria for entering the study were the absence of psychological problems. Data was gathered using the General Health Questionnaire, NASA-TLX, and Demographic Questionnaire.
Results: The mean of the overall mental workload score in the group of nurses working at the Covid-19 wards (70.09 ± 2.51) was higher than the group of nurses working in the non-COVID-19 wards (66.55 ± 2.02). This difference was significant (P = 0.01). There was a significant difference between the mean score of the mental demand, the physical demand, the temporal demand, and the frustration level of the two groups. With the exception of performance, the group of nurses working in the corona ward had a higher mean score in all aspects. In the proposed linear model, 16% of the overall changes in mental workload depended on two variables, which were age and work experience. The work experience was the most influential factor in predicting nurses' mental workload.
Conclusion: The findings of the present study showed the importance of paying attention to the mental workload of nurses as well as personal and occupational factors affecting mental workload in the conditions of the COVID-19 pandemic. Therefore, control and management of effective factors can help reduce mental workload, especially during pandemic conditions.

Abstract
Background and Aims: Administrative employees are often at risk of developing musculoskeletal disorders due to prolonged computer use. Additionally, frequent interactions with clients expose them to a high mental workload and job stress. This study aims to assess the prevalence of musculoskeletal disorders, mental workload, general health, and job stress among administrative employees, to improve their working conditions.
Materials and Methods: The study is a cross-sectional descriptive-analytical study conducted among the administrative employees of an engineering company in 2021, and finally 119 people participated in the study by census method. Demographic information questionnaires and ROSA, Cornell, NASA-TLX, GHQ, and HSE-UK job stress checklists were used to collect data. Data analysis was performed using SPSS software, employing descriptive statistics, independent t-tests, and one-way analysis of variance (ANOVA).
Results: According to the posture assessment with the ROSA method, the average final ROSA score was 4.33±1.03. Examination of mental load with the NASA-TLX index showed that 78% have a high mental load. According to the GHQ questionnaire, the average final general health score is 24.4 ± 11.73. Also, based on the HSE-UK occupational stress questionnaire, more than 80% (103 people) of employees were under severe stress and 12% (15 people) were under critical stress. A significant relationship was observed between occupational stress, body mass index, and age (p<0.05).
Conclusion: Implementing intervention and control measures to improve musculoskeletal disorders, workload, general health, and job stress is essential.
