Abstract
Background: The aim of this study is identification and evaluation of laboratories hazards in Yazd Medical Sciences University.
Methods: This is a descriptive analytic study that was done to identify hazards of laboratories of Yazd Medical Science Universities in 2009.The instrument used for data collection was standardized checklists that before were used in 20 international organizations and 30 reliable laboratories in world, and their reliability and validity were confirmed. The kind of hazards were separated and systematized in these checklists and hardware, human, instruction, and environmental errors were separated from each other qualitative method was applied for evaluation.
Results: According to results, main deficiencies were related to management failure and other defects in order of preference were lack of suitable ventilation, Lack of heating and cooling systems in the laboratory, Lack of safe work instructions and Lack of physical space.
Conclusion: This study showed that the laboratories of universities have many defects and hazards, then adverse events and high probability of occurrence and certainly will be dire consequence, considering the high risk of events is necessary in the short term parallel administrative measures taken in this regard.

Abstract
Background: Today, one of the major factors in reduced efficiency and loss of human resources, is burnout in the staff. This problem has the adverse effects of physical, in addition has psychological adverse too. This study "determine the effect burnout on social support and self-esteem in health care workers". Methods: This analytical cross- sectional study was carried out on 130 staff employed in health centers. They were selected with cluster sampling and simple random. Data was collected by questionnaire (Burn out,Self-esteem,Saocial support). Results were analyzed in spss11.5. Results: 96.2 percent of staff had high self-esteem, and social support at 51/5 percent was high and the dimensions of burnout, the mean sufficiency was 31.78+8.726 of 48, the mean emotional exhaustion in employees was 26.53+12.624 of 54 and the mean of depersonalization was 5.70+5.444 of 30. There was a significant relationship between burnout dimensions, and gender, work experience, marital status, place of work and type of job (p<0.05), So that depersonalization in men and married and workers in urban centers more than other employees,and emotional exhaustion in women, married and in staff who worked at city centers was higher than the other. Ther was a significant correlation and reverse between social support and emotional exhaustion (r=-0.294 & p<0.001), so when the social support in staff was high, the emotional exhaution was less at them. Conclusion: Due to relationship between burnout and social support, the authorities should be considered to reduce stressors and increase job satisfaction in staff by improving work conditions in health centers.

Abstract
Background: One of the assumptions which not discussed in all methods of reliability analysis is that human performance depends on the conditions under which tasks and activities could performed. This condition could be related to both specific and environmental factors. In general, the performance shaping factors (PSFs), or factors influencing performance (PIFs) returns the state to promote safety and reduce human error, so identify and evaluate these factors is considered as a necessity.
Methods: This study is a case study in the control room. Three operational gas transmission companies has been implemented. To conduct this research, initially focused on the identification and selection of factors affecting the performance required for data collection, preparation and completion of a questionnaire, and finally the analysis was done using fuzzy logic.
Results: Analysis of the questionnaires showed that in the opinion of the control room operators, the quality of "number of simulation goals" and "available time" is acceptable, and "the adequacy of training and experience" is not acceptable.
Conclusion: Identify and assess the factors affecting the performance of various industries using fuzzy analysis method is extremely useful to reduce human error.

Abstract
Background: Researches show that the perception of role overload in employees had a relationship with the occurrence of job accidents. Such ways can act as barriers against the harmful effects of work environment on the health and increase in cognitive and support resources including job self-efficacy and organizational support. The purpose of this study was to determine the predicted power of role overload by job self-efficacy and perceived organizational support for safety.
Methods: The current research is a correlation study. Sample consisted of 189 employees in Isfahan Steel Company in 2012 that were selected according to the stratified random sampling method and responded to the questionnaires about demographic characteristics, role overload, job self-efficacy and perceived organizational support for safety. Data we reanalyzed using Pearson’s correlation test and logistic regression.
Results: The results of this study showed that there were significant relationships between role overload, job self-efficacy and perceived organizational support for safety (p<0.01). Also, regression analysis indicated that the variables of job self-efficacy and perceived organizational support for safety significantly predicted almost 11% and 10% of role overload variance (p<0.05).
Conclusion: The research results denote the importance of psycho-social variables in predicting the perception of role overload in employees.

Abstract
Review: Background: With the auto-parts industry to date, still, man, play an important role in various areas of design, operation, maintenance and monitoring of the system plays. All activities in the sectors affected by the special working conditions or career opportunities that are given to us at the time, formed a triad MTO (human, technology and organization) merits. Therefore, the promotion of safety in order to reduce human error, to identify and assess the situation, as it is a necessity. Methods: This study is a descriptive - analytic case study, that, in the control room and maintenance of the operational areas of gas transmission company, has been done. To do research, first identification of critical jobs, then provided a questionnaire to assess conditions performance commons(CPCs). After getting questioners fuzzy results, with use of the fuzzy CREAM, probability controls and the Cognitive Failure Probability total(CFPt) was determined. Results: According to results of basic CREAM fuzzy approach, to all tasks, shift, shift supervisor, shift chief and repairs, tactical control was determined. Conclusion: With method of CREAM fuzzy, f CPCs associated with improved safety performance, including working conditions, the time available to do the work, Availability of procedures. They cause tactical control. According to the results of this study, none of the CPCs, the operator did not reduce performance.
