Background and Aim: Work related musculoskeletal disorders shape a high percentage of physical and mental problems especially in health system work force. This study aimed to evaluate the effectiveness of ergonomic interventions by training the basics of ergonomics and exercise on neck pain in nurse staff of Tohid Hospital of Sanandaj. 
Materials and Methods: This semi-experimental and interventional study was conducted on 60 nurses of Tohid Hospital of Sanandaj who had neck pain in the last quarter of 1394 and they were chosen by random sampling method and were divided into intervention and control groups. Data were gathered using standard Modified Qswestry Neck Pain Questionnaire and pain Numeric Rating Scale. After providing ergonomics trainings and exercises to intervention group, re-evaluation was carried out and the results were compaired to the control group. Data was analyzed using Mini tab 16 software, descriptive and analytic statistics, paired t-test, the correlation coefficient and linear regression.
Results: The average age in intervention and control groups was 35 and 33 years, and the average work experience was 13 and 12.9 years respectively. There was a statistical significant relation between three variables of age, work experience and marital status with the pain intensity variable (p-value<0.05), but gender had no effect on the pain intensity (p-value=0.128).
Conclusion: Standardization of the work methods and implementing exercises, can reduce neck pain and increase physical ability of work staff, which can reduce their work absenteeism and increase their motivation.   

Background and Aim: Ergonomics is the science of refining and optimizing the working environment, occupation and equipment, and matching it with human capabilities and limitations. The purpose of this study was to compare the working environment conditions of the library staff with Ergonomic Principles in selected Universities of Medical Sciences in Tehran in 2016.
Materials and Methods: This is a descriptive and cross-sectional study. The population of this study included all faculty librarians of selected Medical Sciences Universities in Tehran. This study was conducted by census method and all population members (n=85) were studied. The data collection tools were ergonomic checklist in the library environment and a researcher-made questionnaire on the educational status of ergonomic principles. The data were analyzed by SPSS software version 22 after they were collected and entered into the computer.
Results: Based on the obtained findings, it became clear that the status of variables such as body conditions, work space, equipment and environmental conditions was average in terms of ergonomic principles and health variables, and safety factors and welfare facilities were at an undesirable level. In each of the variables of body condition, work space, equipment and safety factors among the libraries of selected Universities, ergonomic conditions did not have significant differences. 
Conclusion: According to the results of this study, it can be concluded that the conditions of the librarians’ working environment in the studied community were not favorable in terms of ergonomic conditions.
