Abstract

Background and aim: Nowadays performance management is used to make organizational agility and improve organizational architecture. The purpose of this study was to determine the effect of organizational architecture on performance management with the mediating role of organizational agility of physical education departments of country's medical science universities.
Methods: The method is a descriptive-survey research and operational and applied in terms of purpose. The statistics of this study included all senior managers and staff of physical education departments in medical universities throughout Iran, selected as a statistical sample for a total of 216. Data collection tools were organizational architecture questionnaire, Baldrige performance standard questionnaire and Sharifi organizational agility questionnaire. In order to analyze the research findings, path analysis and structural equations and SPSS 20  were used.
Results: It showed that organizational architecture and its dimensions have a significant effect on performance management with the mediating role of organizational agility of physical education departments in medical universities of the country. The magnitude of the effect of the mediating variable using VAF was 0.228 and according to the magnitude of the direct effect of the independent variable on the dependent which was equal to 0.799, it can be said that the magnitude of the direct effect is greater than the indirect effect.
Conclusion: In modern performance management, the aims of staffs and the purposes of the organization should be aligned and by creating coordination and providing the necessary guidance by supervisors, people feel more belonging to the organization and make the organization more agile by organizational changes.

Volume 10, Issue 4 (Iranian Journal of Ergonomics 2023)
Abstract
Objectives: Human-made environments can have negative and positive effects on the planet. One of the two-faceted artifacts is the construction of buildings for people's lives, buildings that are being built irregularly and quickly and lead to excessive consumption of fossil resources and energy waste. Become Therefore, one of the most important things in the design of a building is providing its thermal comfort; Comfort that has a direct effect on the cognitive function of humans. In this research, in addition to the topic of thermal comfort, we also discuss fatigue in the classroom, which is one of the factors influencing the cognitive performance of the students.
Methods: In this research, the cognitive performance of people were examined and compared in the range of thermal comfort and the suggested range of the Ashri standard. To investigate their performance in different temperature ranges, 220 architecture students of Ilam universities were selected by systematic random sampling method. The state of thermal comfort, cognitive functions, and fatigue of people was evaluated after measuring environmental factors through questionnaires and standard cognitive function software.
Results: In addition to thermal comfort, which has a direct relationship with the cognitive performance of students, the passage of time is not an exception to this rule, in other words, the cognitive performance of students is derived from thermal comfort and the passage of time, which has a direct effect on academic, mental productivity. and also their practical efficiency. After examining the data in this regard, we reached meaningful results that indicate the highest efficiency of the students in the conditions of proper thermal comfort and the first 60 minutes of the start of their performance.
Conclusion: The results of this research show that even if the thermal comfort of the students' classrooms is provided according to the ASHERI standard, the students' cognitive performance will decrease after 60 minutes from the start of the class.

Volume 11, Issue 4 (Iranian Journal of Ergonomics 2024)
Abstract
Objectives: Musculoskeletal disorders are among the common problems in most work environments and work ability is considered a factor affecting the performance and productivity of employees. In the present study, the status of these two components and their relationship with each other in the staff working in the operating room were investigated.
Methods: The current cross-sectional study was conducted in the winter of 2023. In this research, 96 employees working in the operating rooms of government hospitals in Hamadan, Iran were enrolled by census sampling method based on the inclusion criteria. The data were collected through the Nordic standard questionnaire and the work ability index questionnaire. The collected data were analyzed in SPSS software (version 24) at two levels of descriptive (frequency, mean, and standard deviation) and inferential (t-test) statistics.
Results: In this study, 4 (4.2%) of the participants had one musculoskeletal disorder and the remaining 91 personnel (95.8%) had more than one disorder in their musculoskeletal systems. Average work ability index was 42.3±04.91. The results of the independent t-test showed that the work ability index among people with pain in the neck (P=0.003), shoulders (P=0.001), elbows (P=0.038), back (P=0.011), knees (P=0.001), and legs (P=0.002) were less than those without pain in these organs.
Conclusion: Results indicated the need to pay more attention to the implementation of ergonomic work environment and management interventions to reduce the prevalence of musculoskeletal disorders and thereby increase the efficiency and effectiveness of personnel.

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.
