Consideration of safety principles can decrease the risk of incidents, damage, human and financial impacts, and guarantee a high effectiveness and efficiency and consequently, continuous productivity in an organization. The most important step in providing an optimal safety condition is analysis of the present safety conditions in an organization. In this regard, the present study aims to evaluate the safety risk in the faculties of Qom University of Medical Sciences.

The population of this HSR research includes the Faculties of Health, Medicine and Paramedicine, Dentistry, Nursing and Midwifery, the Iranian Traditional Medicine, and Health and Religion of Qom University of Medical Sciences. This research was performed in 2019, and it has investigated the safety risk resources (fire and explosion, the objects and individuals’ falling, electricity incidents, and secondary risks). The research was performed in three phases including: 1) system analysis, 2) recognition of the safety risks, and 3) evaluation of the safety risk in accordance with the US Military Standard (MIL-STD-882).

Based on the results of system analysis, 228 risk resources were identified in the studied faculties. The results of evaluating the safety risk based on a two dimensional risk matrix (probability- severity) showed that 39 resources have a low and acceptable risk, 71 resources have a high and unacceptable risk, and 118 resources have a medium-level risk.

According to the findings, in spite of the widely accepted assumption of safety of the educational environments, there should be more attention to safety issues in these environments. It is suggested to design a risk management model for identifying and evaluating the risks in these environments and proposing practical solutions for decreasing the safety risks and providing a safe environment.

The work ability index (WAI) is a very important factor in planning a job and selecting suitable people for different occupations, and it can be affected by different factors. The aim of this study was to investigate the effect of insomnia severity on the employees’ work ability in a construction project.

This descriptive-analytical research has studied 213 employees of construction projects. Morin insomnia severity index (ISI) was used to evaluate the insomnia severity. Moreover, work ability was assessed using a questionnaire designed by the Finnish Institute of Occupational Health. Statistical data analysis was performed by SPSS19.

The mean age and working experience of the individuals were respectively 36.2 and 11.27 years. The mean and standard deviation of the insomnia severity index was 6.76(2.5). Multiple linear regression analysis showed that insomnia severity, marital status, type of employment, and smoking had a significant effect on work ability index (WAI); so that the mentioned variables explained about 24% of the WAI variance.

Since sleep disorders and poor sleep quality can significantly decrease the work ability of employees, it is important to pay attention to sleep-rest programs to maintain and increase work ability and productivity.

The occurrence of fire and explosion accidents in the process industries is accompanied by the gradual release of large amounts of energy. The DOW Index is one of the methods of evaluating fire and explosion in the process industries. The present study used the fuzzy logic method to improve the results of the fire and explosion risk analysis method and reduce their uncertainty (error in achieving the correct result).

In the present cross-sectional study, having analyzed the gas separation process, the DOW index was applied to study high-risk equipment. Then, to optimize the behavior of the parameters affecting the DOW index, each weight parameter was assigned to between 0 and 1, and the membership functions of each degree of risk were determined based on the fuzzy rules classification system. The five selected linguistic variables based on membership functions were used to assess the risk level.

Considering butane, the level of fire and explosion risk was 231.3, which was less risky than the fuzzy logic result of 248.6. Methane risk was calculated according to the fire and explosion index of 262.1 while using fuzzy logic that was 265.6. The lowest risk difference was observed between the two methods for ethane (258.9 conventional method and 259.1 fuzzy method results). The risk level calculated by DOW for propane was 243.6, and the risk level was 255.1 while using fuzzy logic.

Although both methods yielded a high degree of risk, fuzzy logic results indicated higher numerical values comparing to the conventional DOW method. Compared to the conventional DOW method, fuzzy logic results are closer to reality with higher confidence levels.

The trans-theoretical model is a model that is very sensitive to changes in the minor progress of behavior. Therefore, the trans-theoretical model is more practical than other patterns of behavior change, which have been considered all or no to measure physical activity. This study aimed to standardize and determine the validity and reliability of the tensile movement questionnaire at the University of Medical Sciences employees.

In this study, after searching the texts and the study of the same questionnaires and tools and among the available and related tools, the initial questionnaire was designed. First, the validity and content of the questionnaire were measured using expertschr('39') comments. Then, the ability to understand the questionnaire based on the opinions of 10 employees was investigated. Finally, to determine the reliability with the experimental-open test method, 30 employees, Cronbachchr('39')s alpha, and the correlation coefficient were obtained using SPSS software.

After performing the necessary reforms with expertschr('39') opinions, finally, the questionnaire with increasing the number of questions of the field of self-efficacy from 6 to 7 questions, the reduction of the number of questions of the interests of stretching movements from 10 to 5 questions, increasing the number of questions of the barriers of stretching movements from 4 to 7 questions and increasing the number of questions of In the validation stage, each 40 of the questions had acceptable content validity (8.0 to 99.0). Also, at least 80% of the questions were diagnosed in terms of the target group acceptable. Cronbachchr('39')s alpha coefficient and correlation coefficient were 86.0 and 7.0, respectively.

A designed questionnaire based on the trans-theoretical model constructs to assess educational intervention to enhance the tensile movements of employees has acceptable reliability and validity.

Measuring the employeechr('39')s performance and examining their behaviors and capabilities are among the principal responsibilities in managing human factors in organizations. A performance appraisal system meets specific barriers. It is required to recognize these barriers to decrease their influences to a satisfactory level to take proper measures to decrease their influences in any organization. This research aims to examine the executive barriers of Article 81 of the Civil Service Act concerning the appraisal of personnelchr('39')s performance in Qazvin University of Medical Sciences.

This research is a kind of applied based on the used objective. Basically, 11 factors were recognized to analyze the barriers (strategic congruence, thoroughness, practicality, meaningfulness, specificity, recognizing efficient and inefficient performance, validity, acceptability and fairness, inclusiveness, openness and ethicality) utilizing literature review and expertchr('39')s view and included in the questionnaire. This questionnaire was distributed among 350 university employees after discovering its validity and reliability. The data were analyzed using the Nonparametric Binomial Test and Friedman method after checking for being parametric (Kolmogorov–Smirnov test).

The results revealed that except for the three variables of being ethical ((mean 4.13), openness (mean 4.46) and acceptability and fairness (mean 4.46), other variables were not recognized as barriers; Consequently,

It is required to take proper measures in the mentioned organization to decrease the influences of these barriers to enhance the productivity of the organization.

Risk perception and attitudes of employees to safety is one of the requirements for the Establishment of safety culture and access to a safer working environment. If the attitude of employees in safety can be improved and completed, their safety performance also improves. So, in order to achieve to an appropriate working environment, it is necessary to measure a personchr('39')s perception of safety. The current study aims to explore the relationship between attitudes and safety performance among employees of a cement industry.

the present study is descriptive sectional, which was conducted among employees of a cement industry in the south of the Iran and in 2018. Information required was collected through the attitude questionnaire and safety performance, and finally 130 questionnaires were completed. The data analysis was carried out through the SPSS software version 24 and the Kruskal–Wallistests and man Whitney and Spearman.

the mean safety attitude was determined by 3.85±0.28. According to this, there is no significant relationship between the level of safety attitude with age (P=0.32) and the degree of education (P=0.36) and Work experience (P=0.52) and accident numbers (P=0.47) and number of education (P=0.320). On the other hand, the safety attitude with safety performance showed a significant relation (P=0.278).

according to the results of the study and the significant relation between the attitude and performance of safety, it can be stated that Through planning to correct safety considerations, can take an important step in the safe operation of worker.

Today human resources are strategic parts of the organizations and are considered as intelligent and valuable assets. Human resources are the most valuable asset of organizations that face the major problem. Research has shown that working life and personal life have an interactive and exacerbate effect on each other. Based on the vast variety of harmful effects that endanger welders health it was tried to investigate the relationship between life quality and working life quality of contract welders in a shipbuilding factory in Bandar Anzali city.

In this analytical descriptive cross–a sectional study carried in 2014, 100 contract welders in the shipbuilding industry in Bandar Anzali was selected with the systematic method, and participated as contract welders. Data were collected with reliable and validated questionnaires include demographic information, life quality questionnaire (SF-36), and Walton life quality questionnaire (1975). Data were analyzed using SPSS18 software by using the Pearson correlation test.

 %84 of contract welders were very happy with their life quality, and %60 were satisfied with working life quality. There was a significant meaningful relationship between life quality and working life quality (P<= 0.00, r= 0.4). The overall living space variable from life quality had a significant meaningful relationship with life quality score changes (P <= 0.042, r= 0.342). There wasn’t any relationship between age, degree, and job experience with life quality and working life quality. But a single job or not having a second job had a significant meaningful relationship with life quality satisfaction and working life quality (P<= 0.023, r=0.262).

 This study showed that there was a relationship between life quality and working life quality. Therefore improvement in either of these two can improve the other one and also help the health promotion of welders.

Improper posture is recognized as one of the risk factors in musculoskeletal disorders. So, operational postures assessment is required to correct undesirable postures and reduce musculoskeletal disorders. This study was conducted to specify the risk level of working postures utilizing REBA (Rapid Entire Body Assessment) and NERPA (Novel Ergonomic Postural Assessment) method and determining its relationship with the occurrence of musculoskeletal disorders in the operational occupations of Abadan Oil Refining Company.

The current study was a cross-sectional and descriptive-analytical study. Using the Cochran formula, 315 of the operational employees of the Abadan Oil Refining Company were studied. Data were gathered by the methods of REBA and NERPA and analyzed using SPSS 20 and statistical tests. The statistical test of the Pearson correlation coefficient was applied to determine the correlation between the results of REBA and NERPA methods. The confidence level of 95% was taken into consideration.

Based on the results obtained from REBA method, the highest frequency percentage in the risk level of postural analysis was attributed to 206 subjects (65.4%) in the medium level, 88 subjects (27.9%) in the low level, and 20 subjects (6.3%) in the high level. Regarding the results obtained from NERPA method, the highest frequency percentage in the risk level of postural analysis was attributed to 158 subjects (50.2%) in the high level, 134 subjects (42.5%) in the medium level and 23 subjects (7.3%) were in the very high level. The statistical test results revealed that a statistically significant relationship was observed between the mean score of REBA and NERPA (P<0.001).

This studychr('39')s results declared that the NERPA method, by regarding the domain and angles of motion more than the REBA posture assessment, investigated the musculoskeletal health and was more worker-oriented.
