Abstract
Background: Due to the prevalence of musculoskeletal disorders among computer users, this study was aimed at investigating the prevalence of musculoskeletal disorders and awareness about the principles of ergonomics among computer users.
Method: In this descriptive-analytical and cross-sectional study, data were collected using demographic questionnaires, Nordic questionnaire, and self-constructed questionnaires. Chi-square, independent t-test, ANOVA, and correlation analyses were used to analyze the data statistically.
Results: The most prevalent signs of musculoskeletal disorders were in the waist, neck, shoulder, back, wrists, and knees. The level of awareness about the appropriate height of monitor and the proper distance between eyes of the operator and monitor was low. Although musculoskeletal disorders were lower in people with high levels of awareness about computer ergonomics, no significant relationship was found between the frequency of musculoskeletal disorders and awareness about computer ergonomics.
Conclusion: Awareness about computer ergonomics could impact on the prevalence of musculoskeletal disorders. So, informing computer users about knowledge of computer ergonomics and creating times to perform stretching exercises while working with computers are essential.
Key words: Musculoskeletal disorders knowledge of ergonomics, computer users, awareness

Abstract
Introduction: Musculoskeletal disorders are one of the most common injuries among computer users, which probably affect the quality of life (QOL) and efficiency.
Methods: In this descriptive-analytical study, 150 Nordic questionnaires were distributed among computer users in Hamedan province and a total of 110 questionnaires were collected. Later, 60 participants (female: n=20 and male: n=40) were evaluated based on the inclusion and exclusion criteria. Musculoskeletal disorders and workplace ergonomic principles were considered as independent variables and quality of life dimensions were investigated as the dependent variables. Rapid Office Strain Assessment (ROSA) was applied to evaluate workplace ergonomic, Nordic questionnaire was administered to evaluated musculoskeletal disorders, and SF-36 was used to assess QOL. Data were analyzed using SPSS software version 22. Independent t-test and Pearson correlation coefficient were also run to analyze the data.
Results: According to the findings, 3% of users were in the safe zone, 16% in the alert zone, and 78% in the danger zone. The findings also showed that the most common pain segments were neck pain (85%) and back pain (75%) in women, but neck pain (52%) and back pain (55%) in men. Additionally, the results showed that ergonomics of the workplace has a negative and significant relationship with the physical dimension of QOL (R=-0/26, P=0/042). Musculoskeletal disorders have a negative and significant relationship with the general health dimension (R=-0/29, P=0/022) and with the pain dimension of the QOL (R=0/29, P=0/022). Moreover, a negative and significant relationship was observed between QOL and BMI (R=-0/49, P=0/001).
Conclusion: Based on the results, workplace ergonomics has an effect on the incidence of musculoskeletal disorders and ultimately the QOL of computer users in non-office environments and computer services

Abstract
Introduction: Mental workload has been raised as one of the most important issues in the workplace. In jobs where there is a lot of workload, due to fatigue and improper scheduling, efficiency is reduced, causing decreased memory, impairs thinking, and decreased learning. Tired people are more likely to choose risky behaviors, such as taking shortcuts to perform their tasks. This study aims to determine the relationship between mental workload and fatigue in bank employees.
Methods: This cross-sectional descriptive-analytical study was carried out on 190 employees of Shahroud Bank in 2019. In order to collect data, the questioning method was done using NASA task load index (NASA TLX) for measuring mental workload and multidimensional fatigue inventory (MFI). Data analysis was performed by SPSS 22 at the significance level of 0.05 using Spearman statistical test.
Results: Bank employees had a degree of mental workload with mean score of 75.06, and two factors of mental stress and efficiency were relatively more important than other subscales. In terms of fatigue, bank employees had an overall degree of fatigue with mean score of 52.46, and two factors of general and mental fatigue were more important in their job.
Conclusion: The results of this study indicate that the overall mental workload is directly related to the activity reduction component. The decrease in activity also has the highest correlation with efficiency, mental, and time subscales, which reduces the activity and productivity of bank employees.
