    Background
    The agricultural sector is one of the most important sectors in production. The safety and health of farmers are important factors that can cause a significant increase in efficiency and productivity. The aim of this study was the assessment of musculoskeletal disorders (MSDs) using the OVAKO Working Posture Analysis System (OWAS) and evaluation of the effect of ergonomic training on posture of farmers.
    Materials And Methods
    In this study, 400 farms were evaluated in 5 major activities including gathering of pistachios by men, gathering of pistachios by women, spading, gathering of pistachio waste, picking of wheat, and fertilizing regarding MSDs using the Nordic Musculoskeletal Questionnaire (NMQ) and OWAS. Then, the required ergonomic training was presented as face-to-face to farmers and again evaluation was performed after the intervention.
    Results
    Low back pain and knee problems had the highest frequency and can be caused by standing or sitting for long periods of time, displacement and manual material handling, and undesirable workstations. A significant relationship was found between age and work experience, and MSDs (P 0.001). Risk level in pistachio and wheat gathering tasks was lowered significantly after the ergonomic interventions and required training compared to before the intervention (P 0.050). However, no significant change was observed in the spading and fertilizing tasks.
    Conclusions
    The results showed that the prevalence of MSDs was relatively high in the studied farmers. Moreover, the level of risk that was obtained according to the OWAS indicated that the working conditions and environment in this industry are harmful. Therefore, taking corrective actions in order to improve the working conditions is necessary.

    Background
    Occupational stress has physical and psychological consequences, and is a major cause of job dissatisfaction among employees, which can reduce the quality of services provided. This study was conducted to examine the relationship between job stress and the prevalence of musculoskeletal disorders (MSDs) among computer users in hospitals (private & governmental) of Gorgan, Iran, in 2014.
    Materials And Methods
    This was a cross-sectional descriptive study. The study participants consisted of 94 hospital computer users. Data were collected using the Nordic Musculoskeletal Questionnaire (NMQ) and Osipow’s Occupational Stress Inventory. Data analysis was performed using SPSS software.
    Results
    The mean score of the subjects studied was 159±77.24. The results revealed that 6.38% of the staff had mild stress, 68.9% mild to moderate stress, 24.47% had moderate to high stress, and none of the employees had high occupational stress. There was no significant relationship between job stress and MSDs of the neck, shoulders, back, elbows, and hands and wrists, but the relationship between stress and MSDs of the waist was significant (P=0.03).
    Conclusions
    The prevalence of MSDs in the studied hospital computer users was high and stress in the workplace can have an important role in the pathogenesis of this disorder.

    Introduction
    Today, the prevention of work-related musculoskeletal disorders (MSDs) is considered as a vital issue and one of the highest national priorities. This study was conducted with the aim of evaluating occupational postures and the prevalence of MSDs among porcelain industry workers of the city of Rasht, Iran.
    Materials And Methods
    This cross-sectional study was done in 2015 on 66 workers, active in different factory units and chosen through stratified random sampling. To determine the frequency of MSDs symptoms in different body parts of the workers, the Nordic Musculoskeletal Questionnaire (NMQ) and Job Content Questionnaire (JCQ) were used. To evaluate the risk of MSDs, the Rapid Entire Body Assessment (REBA) method was utilized. Descriptive statistics, chi-square test, independent t-test, and logistic regression were used for data analysis.
    Results
    Based on the data obtained through the questionnaires, 36% of the studied population had experienced pain at least in one body part in the last 12 months. The frequency of pain in the waist, hand and wrists, and neck was the most. According to the data collected through JCQ, the total score of job content had a statistically significant relationship with subjects’ age and their occupational background (P
    Conclusions
    The present study indicated that, in the studied industry, work posture correction with the help of correction stations and appropriate training is absolutely necessary.

    Background
    Determining quality requirements and quality dimensions is one of the most reliable ways of providing high quality services. The objective of the present study was to investigate the association between quality requirements and quality dimensions according to the points of view of physicians, nurses, and patients.
    Materials And Methods
    This descriptive study was carried out in hospitals under supervision of Medical Sciences Universities, in 4 provinces of Tehran, Fars, Lorestan, and Yazd (Iran). A group of 432 physicians and nurses answered the Quality Requirements Questionnaire which includes the 4 components of competitive, ethical, professional, and accountability requirements. Furthermore, 500 patients answered the Quality Dimensions Questionnaire, including the 11 dimensions of security (safety), professionalism, empathy (friendship), politeness, reliability, accountability, working speed, competency, accessibility, flexibility, and tangibles. The Pearson correlation coefficient and multiple regression method were used to analyze the data in SPSS software.
    Results
    The mean quality requirements and quality dimensions scores in the studied hospitals were, respectively, 3.75 and 3.61, both of which were at a higher than medium level. Moreover, the results of Pearson correlation coefficient suggested that the competitive, professional, and ethical components of quality requirement had a significant and direct association with quality dimensions. However, there was no significant association between the accountability component and quality dimensions variables. Furthermore, based on the results of multiple regression and the determination coefficient, it is possible to claim that approximately 13% of variance in quality dimensions depend upon the mean of components of quality requirements.
    Conclusions
    It can be concluded that work commitment, attention to work, respect for ethical principles, and fair competition at the work place between physicians and nurses lead to the provision of safe and high quality services in hospitals.

    Background
    Fire and explosion hazards are extremely important in processing units. This study was performed to identify the risk centers, the potential damage caused by fire and explosion, and the days of production cessation in the processing company.
    Materials And Methods
    The present qualitative case study was conducted using Dow’s index in 2015. The fire and explosion hazard index and level were calculated for the processing units after collecting the required data. In addition, hazard radius and level, damage factor (DF), actual maximum probable property damage (MPPD), and the maximum probable days’ outage (MPDO) were determined by analysis of the collected data.
    Results
    The results indicated that the fire and explosion hazard level was high in 82% of the studied processing units. Moreover, the potential fire or explosion could cause financial damage of 51 million dollars and production cessation of 296 days.
    Conclusions
    The results of this study showed a variety of possible fire and explosion hazards in the studied processing units. By determining several weakness points in these units, serious engineering controls were suggested to decrease the determined hazard levels. Furthermore, Dow’s fire and explosion index (F&EI) was approved as an efficient technique for assessing the risk of fire or explosion in addition to their damage levels.
