Along with widespread use of computers, work–related musculoskeletal disorders (MSDs) have become the most prevalent ergonomic problems in computer users. With evaluating musculoskeletal disorders among Computer Users can intervent a action to reduce musculoskeletal disorders carried out. The aim of the present study was to Assessment of Musculoskeletal Disorders among Computer Users in Isfahan University with Rapid Office Strain Assessment (ROSA) method and Nordic questionnaire. This cross–sectional study was conducted on 96 computer users in Isfahan university. The data were analyzed using correlation and line regression by test spss 20. and descriptive statistics and Anova test. Data collection tool was Nordic questionnaire and Rapid Office Strain Assessment method checklist. The results of Nordic questionnaire showed that prevalence of musculoskeletal disorders in computer users were in the shoulder (62.1%), neck (54.9%) and back (53.1%) respectively more than in other parts of the body. Based on the level of risk of ROSA were 19 individuals in an area of low risk, 50 individual area of notification and 27 individual in the area hazard and need for ergonomics interventions. Musculoskeletal disorders prevalence were in women more than men. Also Anova test showed that there is a direct and significant correlation between age and work experience with a final score ROSA (p0.001). The study result showed that the prevalence of MSDs among computer users of Isfahan universities is pretty high and must ergonomic interventions such as computer workstation redesign, users educate about ergonomic principles computer with work, reduced working hours in computers with work, and elbows should be kept close to the body with the angle between 90 and 120 degrees to reduce musculoskeletal disorders carried out.

Heat stress is a common problem in industrial workplaces. Thermal stress is a caused reduces concentration of and fatigue increases individuals and thermal condition can be one of accident risk factors .The purpose of this study was validation of Physiological Strain Index Based on Heart Rate in experimental condition. This Semi experimental study was conducted to 16 male in five different temperature conditions (21, 24,27,30,35ºC) in the climate chamber and on the treadmill with two levels of activity 2.4 kph (light physical activity) and 4.8 kph (medium physical activity).Heart rate was measured to for calculating Physiological Strain Index Based on Heart Rate, rate perceived exertion and questionnaire Heat Strain Score index was measured. The correlations between the indices were evaluated using Pearson correlation test and regression analysis. Pearson correlation test showed a significant correlation between Physiological Strain Index Based on Heart Rate and rate perceived exertion (p≤0.001,r=0.96).also a high correlation was observed between Physiological Strain Index Based on Heart Rate and wet bulb globe temperature (p≤0.001,r=0.90). A very high correlation was observed between Physiological Strain Index Based on Heart Rate and Heat Strain Score Index (p≤0.001, r=0.93). The results of this study showed Physiological Strain Index Based on Heart Rate a suitable method for strain heart evaluation is caused by thermal stress because there was an acceptable correlation with heat stress valid indices.

Biorhythm is one of the newest subjects in the field of cognition of mental ergonomics which can be very effective in reduction of work–related accidents or mistakes with no apparent reason. With evaluating Biorhythm individuals can intervention action to reduce job accidents carried out. Thus, the aim of this study was to determine the relationship Biorhythm and work–related accidents in the metal industry. This research is a cross–sectional and analytical–descriptive in the metal industrial Isfahan city of 120 work–related accidents during 2015. The required information was collected from available documents in HSE unit of the company biorhythm charts were drawn based on a date of accidents and participants birthdays, using natural Biorhythm Software V3.02 Conduct. Finally، the data were analyzed using spss version 20 and descriptive statistics.This study showed that the frequency of accidents in critical days and negative section of physical cycle was more than expected. Also the frequency of accidents in critical days and negative section of emotional and intellectual cycles was less than expected. Most type of injury, including cuts to 35.8 percent and the lowest type of injury was torsion with 5 percent. Most limb injury, hands and fingers with 51.7 percent and the lowest limb injury were back at 2.5 percent. Accidents outbreak in physical cycles was 38.3 percent. These 120 accidents in additionally were causing 120 loss of working days in effect accident. Most percent of loss of working days were for 20 to 30 days with of 39.2 percent. Most percent of loss of working days were for 20 to 30 days with of 39.2 percent. Due to the physical nature of the work activities in the metal industry can be stated that the study showed that in physical work activities, frequency of accidents in critical days and negative section of physical cycle in which the person is not physically ready to do the job was more than expected. Therefore, by training and increasing the knowledge of workers regarding biological cycle and its effects on mental, emotional and physical status, each person effects can make some changes to their work plans during days that they do not feel well, physically or mentally, in order to prevent the likely accidents.
