Abstract
Background: Focusing on the organizational conflict and the depression in the main trainers of an educational system, the faculty members are very necessary because the increased negative organizational conflicts lead to a lower public health. Therefore, the aim of this study was to investigate the relationship between the job depression and the organizational conflict in the faculty members.
Methods: The present study was a correlation type research and the statistical population included seven faculty members of the department/school/institute of medical sciences in the city of Hamedan with 244 faculty members as per the census of 2017. For the collection of the data, the Goldberg and Hiller questionnaire was used for measuring the depression and the organizational conflict inventory. Using descriptive statistics such as Pearson's correlation coefficient and regression analysis, the data were analyzed for modeling by the SPSS Statistics 24 software.
Results: The mean scores of the depression, the organizational conflict, the conflict with the manager, the similar degrees, and the control were 0.8, 22, 6.7, 7.4, and 7.9 respectively. The results showed a significant and positive correlation between the depression and the organizational conflict (P=0.001, r=0.42). Such correlations were also observed in the two dimensions of conflict with the others (P=0.001, r=0.62) and conflict with the control (P=0.001, r=0.43). However, no significant correlation was observed in the dimension of conflict with the manager.
Conclusion: The different factors of conflict studied in the society must be focused on, addressed, and improved in light of the positive and direct correlations observed between the organizational conflict and the job depression.

Abstract
Background: The design of tools may play an important role in development of the problems related to hands and arms. The health and satisfaction of those who use these tools can be affected by the improvement of ergonomic tools. This research aims to assess the local discomfort caused by the usage of common pencils comparing to the ergonomic ones.
Methods: 50 right-handed students (girls only) participated in this study. They wrote one paragraph using all the writing tools that were being studied in this research. At the end the comments were collected using the LPD questionnaire and were analyzed by t-test and Mann-Whitney test and SPSS version 23.
Results: The results of the CHQ questionnaire showed that this questionnaire could be a useful tool for assessing the comfort of using writing tools among students in the school environment. Also, the results from the LPD scale showed that this scale could be very helpful for assessing local perceived discomfort among school students. In the second part, the results of the comparison of the mean of data from the CHQ questionnaire and the LPD scale showed that there is a significant difference between the common pencils and the designed pencil for comfort and local perceived discomfort.
Conclusion: It was found that common pencils cause pain, pressure, inflammation and numbness in the hands and forearm and shoulder. And the use of designed ergonomic pencil will reduce the pressure and pain on the hands and shoulders.

Abstract
Background: Undesirable sit-up and deviation from desirable status is one of the factors affecting the health of students in the classroom. The purpose of this study was to evaluate the relationship between posture and musculoskeletal pain in boys 9 to 13 years old.
Methods: In this correlation study, the population consisted of all boy students in the primary city of Birjand. 60 students were selected as a sample group based on random-cluster method. Two video cameras were recorded 30 minutes of sitting position for every student. The anthropometric characteristics of subjects including height, weight, etc., were measured with a standard tool. The back and neck pain were collected using a modified Nordic questionnaire. Moreover, the kinovea software was used to analyze the flexion and rotation angle during sitting. The statistical calculations were applied by Kolmogorov-Smirnov normality test. The ETA correlation coefficient also was used to identify the relationship between variables. All statistical calculations performed using SPSS version 21.
Results: The result indicated significant relationship between bending and rotation angles with both neck and back pain (P≤0.05). Therefore it would be noticed that improper sitting can be accounted as a cause of muscle-skeletal pain in boy students based on bad postures during sitting.
Conclusion: According to the results, the posture of students while sitting in class is inadequate and harmful. Thus performing some intervention and education for students is recommended.

Abstract
Background: Many workers, especially welders, have awkward postures during their working hours. Evaluating such kind of postures is done with the aim of corrective actions. Therefore, the present study was conducted to evaluate the activity of welder's muscles in common welding postures working on gas transmission pipelines.
Methods: This cross-sectional descriptive-analytical study was performed on 15 welders of the Iranian Gas Transmission Co. After the required analysis, three postures that were most used working on the gas transmission pipelines were identified to evaluate muscle activity. The surface electromyography (EMG) activity of the erector spinae, biceps femoris, vastus medialis, gastrocnemius medialis, gastrocnemius lateralis, tibialis anterior, rectus abdominis, abdominal internal oblique, abdominal external oblique, and semitendinosus muscles are evaluated in three postures. They are analyzed based on the maximum voluntary contraction (MVC).
Results: The results indicated that the mean of muscle activity in the kneeling posture is significantly lower than two other postures (P<0.001). The mean activity of each muscle in different postures were compared and evaluated. The highest activity was related to the tibialis anterior, vastus medialis and biceps femoris. Abdominal muscles have the lowest activity.
Conclusion: The muscle activity of the welders in the evaluated postures was very high. Based on the findings of this study, the muscle activity was strongly affected by the type of posture and angle of the joints, so the muscles’ activity in the kneeling posture was lower than the two other postures due to the suitable angle of joints and the direct transmission of body weight.

Abstract
Background: Inadequate lighting in the workplace can cause unconventional changes in the posture of office workers. Poor ergonomic conditions in the office cause inappropriate postures during work and increase pressure on the musculoskeletal system which can cause some disorders in long-term. In this study, the relationship between work environment lighting with the prevalence and severity of musculoskeletal pain among office workers has been investigated.
Methods: In this study, the intensity of local illumination at work surface and at the perpendicular surface (perpendicular surface to the work surface and at the height of workers eye), and intensity of general lighting was measured based on the standard of The Illuminating Engineering Society (IES) using the SEKONIC, C-7000 SpectroMaster. Also, to assess the prevalence and severity of pain of musculoskeletal disorders, a Nordic Questionnaire and a Body map index were used respectively. To assess the office work strain, Rapid Office Strain Assessment techniques (ROSA) were used. Data were analyzed by SPSS 21.
Results: The results showed that the average intensity of general lighting, local lighting at work surface and at the perpendicular surface were 30.6%, 33.9%, and 38.4% respectively, which is lower than required illumination intensity of Occupational Exposure Limits (OEL). The neck and waist had the highest prevalence of the musculoskeletal disorders among the workers. The highest frequency percentage of scores in the ROSA method was the score 5 (41.7%) which had a significant correlation with illumination intensity.
Conclusion: Illumination intensity can be considered as one of the important factors affecting posture in administrative staff. Therefore, the improvement of illumination intensity can decrease the severity of musculoskeletal pain and improve the body postures of the staff and, consequently, increase their comfort.

Abstract
Introduction: Establishing order depends on different arrangements in many aspects of lif. The fulfillment of order should be along with good policy and developed strategic principles, at the micro level and with the correct, firm and prudence legislation in the institutions and governance. Forensic ergonomics is one of the fields that helps this aim. Today it has become more widely used due to the creation of legal problems in the field of accidents and injuries. Therefore, this study reviews articles about forensic ergonomics and the effect of ideology on it.
Materials & Methods: This is a review study. The English articles published in Pubmed, Scopus, and Google scholar were chosen using keywords such as “forensic ergonomics” and “forensic human factor” without time limit; at least 3 articles were eligible.
Results: In the review section, the results showed that there is an agreement in the definition of forensic ergonomics, but there are very few studies. The results also showed that the use of forensic ergonomics is increasing, and the prospect of this area is positive. In the analytical section, the results also indicated that the review and suggestions for the creation of laws in the field of accidents should be assigned to the judicial system, not the executive or legislative system.
Conclusion: In order to progress in the field of legal ergonomics and to prevent the impact of ideology and politics on legislation, there is a need for further introduction and training of experts in this field and paying attention to the rational and scientific principles.
