Increase of job satisfaction and reduction of job burnout are among the most challenging concepts in the field of occupation / organization. They are also considered as the basis of many policies to increase the productivity and efficiency of an organization. One of the most important causative factors of burnout is personality traits. In this context, schemas, as the personality traits described in personality development psychology, play a significant role. Therefore, investigating the relationship between these transformational patterns and occupational burnout can be considered as an essential issue in the field of occupational health

This descriptive study was conducted on 220 personnel of Public Health School in Yazd Shahid Sadoughi University of Medical Sciences. The participants were selected using simple random sampling method and the data were collected using the Maslach Job Burnout Questionnaire and the Young Short-form Short-Scale Questionnaire. Data were analyzed using Spss 20 by applying the central tendency indicators, t-test, and Pearson's correlation coefficient to test the hypotheses.

The results of this study showed a negative but significant relationship between most of the early maladaptive schemas and the two subscales of burnout (emotional exhaustion and depersonalization). The results also showed a positive and significant relationship between the schema score of release / instability and individual performance (r = 0.206, p-value = 038.

According to the results of our study, it can be said that some of the areas of early maladaptive schemas cause stress in the university personnel and repetition of these stresses causes burnout. Therefore, understanding these areas and planning to prevent and control them are practically required to promote organizational productivity in the field of occupational and industrial research.

Employees' job satisfaction is one of the most important issues in the field of organization's human resources and their spiritual health. It is also one of the essential aspects of people's health and well-being. The goal of this study was to investigate the relationship between Spiritual Health and Job Satisfaction in Legal Medicine staff.

This descriptive-correlational study was carried out among the staff of Legal Medicine Organization in Iran. Data collection instruments included questionnaires of spiritual health, job satisfaction, and demographic information. A total of 321 questionnaires were completed and investigated. Descriptive statistics and Pearson correlation test were run by SPSS 16 for data analysis. The significance level of the test was set at 5%.

The highest mean was related to job satisfaction (53.50), while the lowest was attributed to salary satisfaction (19.72). A significant association was found between job satisfaction and spiritual health (p = 0.049, r = 0.102). Moreover, significant associations were observed between spiritual attitude towards God and job satisfaction (p = 0.032, r = 0/120), spiritual attitude to self and job satisfaction (p = 0.022, r = 0/128), spiritual health and satisfaction of the supervisor (p = 0.020, r = 0.139), as well as spiritual attitudes towards God and satisfaction of supervisors (p = 0.035, r = 0.118)  and colleagues (p = 0.042, r = 0.114).

Increase of the staff spiritual attitude can promote their spiritual health. Therefore, conducting up-to-date scientific courses on spirituality training can be effective in planning for the promotion of spiritual health, job satisfaction, and performance among the organization's staff.

Occupational stress is one of the most important phenomena in the workplace. Mental health, as an important factor in all personal, social, and occupational life aspects, is one of the areas of interest in mental health. The purpose of this study was to determine the relationship between job stress and mental health among workers of central iron ore in Bafgh City, Iran.

This was a descriptive correlational study. The statistical population included 2400 people (1600 workers and 800 employees) working in central Bafgh iron ore in 2014. The sample size was estimated as 331 using the Morgan and Krejcie table. Approximately, 216 persons were employed in the labor sector and 115 in the employment sector. Data collection tools included the Goldberg general health questionnaire (GHQ) and Depression Anxiety Stress Scales (DASS). The DASS was designed in three parts. The first part included demographic data (7 items). The second section had 28 questions and dealt with the participants' general health status. The third part included 42 questions and was about occupational stress. Later, Spss21 was used and Pearson correlation coefficient and regression tests were run to analyze the data and test the hypotheses.

The results showed that mental health was higher in employees, while job stress was higher among the workers. This indicated a significant association between job stress and mental health in both employees and workers. However, regarding the demographic variables, only gender was related to mental health and rest of the demographic variables had no significant relationship with mental health and job stress (5≥participants).

Occupational stress was related to mental health in employees and workers; this can affect the level of production and product quality. Furthermore, occupational tress and mental health not only affect the workers and employees, but also expose the society and other people at risk.  Consequently, it is necessary to plan and render different services at the occupation environment to decrease job stress and improve the current situation.

Job satisfaction is considered as an important factor for increasing efficiency and individual satisfaction in the organization. The purpose of this study was to test the structural model of positive organizational behavior and job satisfaction with the mediating role of job stressors.

Research design was correlation through structural equation modeling (SEM) and the sample consisted of 150employees that working in university of Bojnord, who were selected by stratified random sampling method. Participants in this study were measured using occupational stress, psychological capital, and job satisfaction questionnaires. Reliability and validity all of the questionnaires were accepted. Structural equation modeling (SEM) through Amos-23 and SPSS-23 software packages was used for data analysis. In addition, Preacher and Hayes’ SPSS Macro program was used for testing mediation.

The results showed that the proposed model fits the data properly. Positive organizational behavior has a direct effect on job satisfaction and job stressors (p<0.0001). Also, the mediating effect of job stressors in the relationship between positive organizational behavior and job satisfaction was confirmed (p<0.0001).

Therefore, organizations can increase their job satisfaction by reducing job stressors and training and reinforcing positive organizational behaviors of their employees.

One of the important and growing organizational considerations is the staff health and safety. Workplace events cause death and disability in a large number of employees annually. So, employers have seriously focused their attention and organizational resources on this important issue. The purpose of this study was to investigate causes of the fatal industrial-production activities using the Morte's technique and to provide management solutions to reduce the incidents caused by the workshop in Yazd province, Iran.

Initially, a total of 57 fatal accidents were identified and investigated in Isfahan industrial enterprises. Among this number, 12 cases of work-related incidents were studied. In the second stage, events were analyzed by Morte tree. This descriptive, correlational, and applied research was a fieldwork conducted as a library study to collect the required data.

The results showed that most causes of defect accidents were among the management system factors and covered 40.4% of the total causes. This was followed by the human errors and defects in working processes (36.5%), defects in fences and barriers (19.2%) in rescue process, and other causes of accidents (3.9%).

By adopting safety measures in compliance with the protective regulations, extent and severity of the accidents can be reduced to a large extent. Many good practices can also be prevented by appropriate management measures.

The oil and gas industries are considered as the most important industries in Iran, where a significant part of the budget depends on these two areas The significant health and safety implications of these industries on the staff and stakeholders have also been highlighted.

The present study was conducted to identify and assess the safety and health risks of the Fars Mountain Seismology project using HAZAN method in 2016 and 2017.  The hierarchical task analysis  (HTA) was used to analyze the main tasks of the main occupations: digger, surveyor, shooter, drivers, and helicopter pilot . The risk assessment process identified in the HAZAN method was based on the qualitative matrix.  In HAZAN, 50 health and safety risks were identified.

The results showed that eight risk factors (16%) were unacceptable, 25 were unsatisfactory (50%) and 17 (34%) were acceptable.

The results showed that the aviation and land transport processes as well as the traffic on mountain routes were the most expensive activities in the project.  Finally, management solutions were proposed to reduce the risk level related to the most important project activities

Creation of anthropometric database in any age group is one of the most important issues in designing and manufacturing of used equipment. The aim of this study was to determine the anthropometric characteristics of nurses of kindergartens and preschools in Isfahan in the age range of 2 to 6 years and to create an information reference.

In this applied study, 700 healthy male and female boys were selected randomly from cluster sampling from nursery schoolchildren and preschools in Isfahan city. 36 anthropometric measurements of them were cross-sectional in the academic year 1396 to 1397. And indicators and statistical percentiles (5.50 and 95) were extracted.

Statistical indexes and percentiles were presented as an anthropometric database in 5 age groups and in two sex groups. Age and sex were influenced by most anthropometric variables and significant difference (P <0.05). .

The age and sex are two factors affecting anthropometric variables. Therefore, it is necessary to use the anterpometric database of the same age group and gender in the design of the equipment.

The overwhelming development of cities has increased the consumption of natural gas, which requires implementation of a gas network and installation of branches for consumers. This has increased the speed and stress of engineers supervising the gas company activities. The purpose of this study was to determine the dimensions of burnout in supervisory engineers of Fars Province Gas Company and to present appropriate solutions to control and eliminate them to improve their health and safety.

Data were collected using a researcher-made questionnaire, in which the emotional and occupational fatigue was assessed using the Maslach Burnout Questionnaire. The validity of the questionnaire content was assessed qualitatively using the panel of experts' opinion and its reliability was calculated by Cronbach's alpha. Data were analyzed by SPSS 21

The results of regression test showed that psychological factors and work pressure had a significant relationship with participants' demographic characteristics as well as environmental and biological factors (P <0.05). Emotional exhaustion and consequent stress were observed among supervising engineers due to their high job stress that causes job burnout and depression among them. The mean emotional exhaustion was 96.2%.

  The results showed that more than 78.55% of the observers considered that their health and safety status was undesirable.  Work clothes and other personal protective equipment components had a significant relationship with pain in each of the studied areas. Similarly, a signifiacnt association was observed between the components of psychiatric periodic examinations and skeletal disorders (P <0.05).
