Abstract
Background and aims: Promotion of workers’ health and safety is one of the main tasks of managers and planners. One of the important sciences that can assist managers to achieve this gool is ergonomics. This article presents results of workload and job satisfaction survey in a heavy metal components manufacturing company in Tehran, in 2010.
Methods: This cross sectional study conducted by survey of all operational workers. Workload is survived by NASA-TLX questionnaire that contained six dimensions and job satisfaction evaluated by short version of Minnesota questionnaire .
Results: Job satisfaction questionnaire ’s reliability which assessed by Cronbach’s Alpha was 0.91. In addition, data analysis results declare that the average job satisfaction scale was 65 and at medium level and workload with 85.11 as average scale was at the high level. Effort and physical loads were two dimensions which have high amount in the workload In addition, no statistical significant relation was observed between the total job satisfaction score and workload score. (p<0.05). While the performance dimension showed a positive relationshipwith job satisfaction, frustration demonstrated a negative relationship with job satisfaction.
Conclusion: In order to improve the work conditions the administrative and technological controls should be implemented and actions need to be taken to modify workload dimensions specially, two dimensions with the high amount and dimensions that have relationship with job satisfaction.

Abstract
Background and aims: Transportation and driving have key roles to social life and work, in today’s world. Regard to high needs to concentration and attention and also total health, physical and mental, of drivers, the present study has been conducted aimed to survey the relationship between occupational stress and musculoskeletal disorders among trucks and trailers drivers, 2014-15.
Methods: 173 divers participated in this cross-sectional and analytical research. Researchers used three questionnaires to gather data: Demographic, Body map and drivers stress inventory (DSI). Also, analyses have been done utilizing SPSS V20.
Results: Studied drivers were 43.61±9.25 years old. Their work experience was 18.92 years as mean (±9.62).146 ones (%88.5) experienced musculoskeletal pain at one part of their body, at least. Average of occupational stress score was measured 247.87 with 18.57 as standard deviation. Occupational stress differentiation between participants with and without musculoskeletal problems analyzed and it was most significant about tights, hands, and right elbow (p<0.05) and also, low back part (p<0.1).
Conclusion: Respect to his results, truck driving as a job, in Iran from view point of stress and based on DSI tool, is in medium degree. In addition, stress is correlated with musculoskeletal pain prevalence. Development and applying drivers’ occupational stress management plan all around the country can lead to safer roads, fatal crashes reduction, and increase in drivers’ health.

Abstract
Background and aims: TOPSIS as a method in Multi criteria decision making (MCDM) helps decision maker(s) to organize and analyze problems, and to rank alternatives. In this paper, the ergonomic risks factors which may influence health are addressed in a manufacturing company in 2014. Then TOPSIS method is applied to select the different halls that are prioritized in terms of action level and ergonomic conditions.
Methods: This cross-sectional study was done as a descriptive-analytic procedure. It considers conditions in seven halls and 13 tasks were included. Required Information gathered by the demographic questionnaire and ART method for repetitive task assessment. Also TOPSIS as a suitable multi criteria decision making instrument was used to prioritization of company halls. SPSS V20 and MATLAB are used to compute the variables.
Results: The total exposure score based on the ART method equals to 30.07±12.43 were calculated. Data analysis from ART illustrated that 179 cases (74.6% of tasks) were in the high level of risk area and 13.8% were in the medium level of risk. ART-TOPSIS results revealed that Leher hall has been placed in the top lists of action level and degradation hall in the end of this list.
Conclusion: obtained results showed that the TOPSIS method can be used to ergonomic and human factor engineering challenges successfully. It seems that, macro and micro ergonomic solution presentation besides employee's collaboration, based on the scientific decision-making procedures (with employer's cooperation motivation), can leads to effectiveness in health level enhancement of industrial setting increasingly.

Abstract
Introduction: The changing nature of work in today's world has caused a large number of people to be engaged in sedentary jobs. In such cases, lack of physical activity can lead to non-communicable diseases and increase morbidity and mortality. The purpose of this study was to provide a step-by-step descriptive design, implementation, and evaluation of a physical activity promotion program in the workplace using an intervention mapping approach.
Methods and Materials: In this study, evidence-based and theory-based intervention design, guided by the steps of an intervention mapping approach, to promote physical activity in the workplace is described.
Results: Physical activity intervention was performed based on workplace as well as individual and interpersonal, environmental, and organizational goals. Interventions include using the Ministry's gym for all employees, consulting with sports experts and instructors, increasing the Ministry's sport administration programs, holding a cultural festival for the participation and cooperation of all managers, employees and their families, photography, and painting competitions, and helping physical activity assistants for follow-up and feedback. Communication channels included posters, pamphlets, labels, motion graphics, stands, booklets, and movies.
Conclusion: Intervention mapping ensures transparency of all components of the intervention and provides a systematic, theory-based, and evidence-based approach to interventions development in the sedentary behavior changes among employees.
