Abstract
Introduction: Nowadays, computers are integral component of all workplaces. Moreover, employees healthstatus is directly associated with their occupational stress level. The aim of the present study was to investigative the effect of ergonomic training and intervention on reduction of occupational stress among computer users in welfare organization in Rasht city.
.
Material and Method: In this semi experimental study, 283 female computer users, who were 30-40 years old with work experience of 5-15 years, were chosen as sample. The participants had at least one year
experience of using computer and they had worked 3-4 hours with computer daily. The Osipow occupational stress questionnaire (1987) with Cronbach alpha 87% was applied for estimation of occupational stress. Then, 46 participants with moderate to high level of stress were selected and randomly divided into case ad control groups. Participants in a case group received practical and theoretical ergonomic training and also interventions (including armrest, foot rest, cushion, posture correction, reduction o work time duration, adjustment of the seat height according to individuals height, adjustment of eye-monitor distance). Finally, the obtained data were compared to those of control group, using covariance.
.
Result: According to covariance analysis, ergonomic training and interventions lead to reduction of occupational stress of computer users.
.
Conclusion: Training computer users and informing them of the ergonomic principals and also providing interventions such as correction of posture, reducing duration of work time, using armrest and footrest would have significant implication in reducing occupational stress among computer users.

Abstract
Introduction: Nowadays, working in any computer work stations, named visual display terminal (VDT), was widespread and has become popular in our lives. Due to the increasing trend of using computers in the administrative and social institutions, prevalence of eye-related signs of working with computers is still increasing and it is one of the most important health issues. Computer jobs are low-mobility and require little energy to do physical work, but require more cognitive processing and mental focus. Visual fatigue is an occupational hazard for people working with computers. Eye fatigue has symptoms such as headaches, job discomfort, and eye pain the purpose of this study was to have a systematic review on eye fatigue, dry eye and eye blink among people working with visual terminals.
Material and Methods: Internet search databases and search engines were used to find articles with focusing on the impact of risk factors on eye indexes on computer users. In this study, related articles were obtained from websites, including: PubMed, Google Scholar, Scopus and Web of Sciences. The keywords were used to search in these websites were: computer user, eye fatigue, dry eye and eye blink. Accordingly, after finding 115 relevant articles from the related sites, 17 articles were finally selected.
Results: Findings show that using computer cause many problems in the eye. Duration of using the computer, the type of work with the computer, the mental load, the distance from the monitor, and also long-term use of the computer without break in during work can cause dry and fatigue eye in users, which is one of the most common ocular problems among computer users.
Conclusion: According to the finding and results recommended to reduce of dry and fatigue eye, distance of users from the monitors, be more than 50cm, use 20-20-20 law to rest user’s eyes, and Positioning the monitor be 15-20 degrees below the user’s line of sight. Also, too much focus on the screen reduces blinking and resulting in dry eyes. In order to prevent dryness of the surface of the eye, it is recommended that the eyelid be optional even if possible. Increasing the contrast of the monitor can be helpful in reducing stress and strain on the eye while working with a computer and using glasses instead of lenses to correct refractive errors and one of the ways to control and improve dry eye is using artificial tears by computer users.

Abstract
Introduction: Work-related musculoskeletal disorders (WMSDs) are one of the most important causes of absenteeism, increased costs and human injuries, which are very common in computer users. The purpose of this study was to investigate the effect of 8 weeks of corrective exercise on reducing the prevalence of musculoskeletal disorders (MSDs) in computer users working in a gas company.
Material and Methods: This cross-analytical study was conducted on 101 computer users working in a Gas Company in Qazvin city in 2019. Fourteen people participated in 8 weeks correction training intervention program (16 sessions in 1 hour and 2 times a week). Nordic questionnaire and body map were used in order to investigate the prevalence and severity of MSDs. The data were analyzed using Kolmogorov-Smirnov, Cramer V, McNamar, Paired sample t-test and Wilcoxon tests in SPSS version 23 software.
Results: The most common disorders were shoulder (64.3%), waist (42.9%) and neck (35.7%) regions among computer users during the last week before intervention. The prevalence of MSDsby strength and flexion exercises in neck and shoulder regions with 95% and 99% confidence showed a significant decrease before and after intervention. The incidence of discomfort in the waist region decreased by 35.8% after intervention and in other regions decreased by at least 7.1%.
Conclusion: The results of this study showed that implementation of corrective training intervention program by exercise specialists can increase muscle stretch and consequently decrease the prevalence of MSDs7.1%- 64.3%.
