Due to the increase of anxiety caused by COVID 19 in medical staff, it is necessary to identify and develop strategies to deal with anxiety among them. Therefore, this study aims to investigate the role of exercise and practicing religious beliefs on medical staff's anxiety caused by coronavirus.

This is a quasi-experimental study, performed through pretest and posttest. The study population was medical staff of hospitals in in several provinces of Iran, who provided services to patients with COVID 19. The sample size was 54 people, who were randomly and purposefully selected. The research instrument was the anxiety questionnaire of Coronavirus designed by Alipour et al. (2017). ANOVA, dependent t-test, and LSD post hoc tests were used to analyze the data after checking the normality of the distribution of scores by SPSS software.

The results showed that there was a significant difference between pretest and posttest scores in the groups of voluntary exercise (t=21/91), voluntary religious practice (t=14/15), and random exercise (t=3/84), which shows their effect on reducing anxiety in the treatment staff. There was no significant difference between pretest and posttest scores of the control group (t=0/566) and random religious practices (t=1/595). The results also suggested that the groups of voluntary religious practice, voluntary exercise, and random voluntary exercise experienced the lowest amount of anxiety, respectively.

Exercising, willingly or unwillingly, reduces anxiety in the treatment staff due to predominance of its physiological aspects. However, practicing religious rituals reduces anxiety, only when it is based on the individual's will.

The main purpose of this research is modeling based on PHAST software, and achieving safe distances for deploying firefighting teams at the time of accidents as consequences of leakage, fire and explosion in some of the process equipment of Persian Gulf Star Gas Condensate Refinery.

This descriptive cross-sectional study was conducted in 2019. In this study, two possible types of fire in the single distillation process (sudden fire and burst fire) were investigated. The explosion of one of the towers was also simulated to determine the extent of the effects of these events.

In the jet fire of the output line of furnace 101, the minimum distance from the accident site should be considered 120 meters, which according to the standards related to heat flux, up to a distance of 66 meters, the probability of death will be 100%. In addition, due to the pressure wave created in the wide range prone to flash fire in the rupture of the output line of furnace 101, the explosion of the fire station also affects.

According to the data obtained from the simulation, the authors concluded that in the event of leaks in the open air (flammable materials), the greatest danger threatening people and equipment, and consequently the firefighting team, is the occurrence of flash fire, which usually covers a wide area.

Nowadays, in order to improve the level of Health, Safety and Environment (HSE) culture of employees, organizations have reached this important conclusion that the weaknesses and strengths of the system should be identified .This is done by periodically evaluating the level of HSE culture, in order to determine and apply the targeted promotion. Therefore, the aim of this research is to evaluate the level of HSE culture among the employees of Gas Company of Northern Khorasan Province.

This is a descriptive-analytical, cross-sectional study conducted in 2009-2010. The questionnaires were self-administered and semi-supervised by the participants. The statistical population included 400 official, contractual and non-official employees. Simple random sampling method and Cochran formula were used to select the statistical population, which included 198 employees in all organizational levels of the company. Data were analyzed using SPSS software version 23, and descriptive statistics, inferential statistics and correlation tests. HSE culture promotion strategies were identified and presented after reviewing and analyzing the scores.

Compared with the determined limit using the relevant formula (number 177), in this study, the general level of HSE culture of North Khorasan Gas Company was evaluated as positive with a score of 198.42. The minimum and maximum HSE culture scores of the participants were 131 and 281, respectively. Education indicator had the most positive effect, and disregard and violation indicator in rules of HSE had the most negative effect on HSE culture score.

The positive level of HSE culture in a high percentage of employees, compared to the defined boundary, shows successful implementation of HSE management system indicators, such as training, employees' participation, rules and instructions, and commitment of managers are priority in the company under study.

Heath is one of the most important issues discussed in all organizations including the arm forces. This study aims to provide a suitable substrate for outsourcing health, safety and environment (HSE) activities in the armed forces, by identifying the various aspects of outsourcing HSE, and reviewing the existing systems related to HSE.

This documentary research was conducted among the arm forces in 1397-1400. In this study data were extracted using the keywords of the documents searched in the databases. Raw data were provided to experts in the form of questionnaires. Questionnaires were developed by Delphi method and an expert panel.

Results of the questionnaire on different aspects of HSE outsourcing by the panel of experts showed that 17 subsets in 3 areas of health (6 items), safety (6 items) and environment (5 items) are conceivable for outsourcing (military force use external organizations or individual to meet their necessary needs). After developing the systems evaluation questionnaire (A set of laws, regulations, bylaws, instructions, and directives that are developed to address standards of a particular subject, job, or profession), 14 instructions/bylaws related to 10 requirements (what should be observed in systems related to the armed forces) were evaluated, and the results showed that on average, 39% of the systems cover the requirements, 29% need to be reformed, and 32% of the requirements require major reforms.

Findings of this study indicated that the use of systems in a country cannot fully meet the requirements of the armed forces, and requires some fundamental reforms. Also, not all aspects of HSE can be outsourced, and some requirements need to be considered before outsourcing.

The complexity of working conditions in organizations, including employees' distrust, and challenging working conditions combined with a negative feeling, has led to a sense of frustration in organizations, which can be due to the conditions regarding the community and the organizational climate. The purpose of this article is to investigate the relationship between organizational cynicism and job burnout with mediating role of organizational silence in lifeguards of Tehran municipal pools.

The research method was causal, and applied in terms of purpose.A survey approach was used to collect data. Tools of collecting data were Kalagan Organizational Skepticism Questionnaire (2009), Dain et al.'s Organizational Silence Questionnaire (2003) and Maslach Questionnaire (1985) for Job Burnout. The statistical population of this study included 436 active lifeguards in Tehran municipal swimming pools. Sampling method was simple random. Descriptive and inferential statistics were used to analyze data, and LISREL 8.8 software was used for modeling structural equations.

Results demonstrated that organizational cynicism through organizational silence, affects job burnout among lifeguards in Tehran municipal pools. The effect was estimated to be 0.56 (z=4.96, ρ≤0.01). It seems that negative attitude of lifeguards, due to their fewer roles in decision-making and lack of information in the organization, causes them to react through silence, and the consequence of such silence, leads to job burnout

As a result, the attitude of lifeguards towards their workplace can be negatively accompanied by unpleasant feelings, helplessness and anger, which seriously affects their performance Therefore, it is suggested that management, along with the presence of lifeguards in organizational decision-making processes and transparency, reduce burnout regarding this vital profession.

One of the most important key factors in achieving development is the optimal use of human resources. Therefore, it is of especial importance to pay attention to the talent and role of women in managerial positions. The purpose of this study is to investigate the relationship between glass rock, and job motivation and organizational maturity in female employees of Lorestan University of Medical Sciences.

This was a descriptive-correlational study. 367 female employees of Lorestan University of Medical Sciences were selected based on Morgan table and available sampling. To collect data, questionnaires regarding glass rock, organizational maturity and job motivation were used. Data were analyzed using Pearson correlation and regression.

The results showed that there was a significant negative relationship between glass rock, and job motivation and organizational maturity of female employees of Lorestan University of Medical Sciences. The results of regression analysis also showed that the glass rock was able to predict the job motivation and organizational maturity of female employees.

According to the results, the glass rock has a negative relationship with job motivation and organizational maturity of female employees. The presence of glass rock in the organization reduces the organizational maturity and job motivation of female employees.

Despite increasing advances, various industries are still involved in various accidents caused by Health, Safety, and Environment (HSE) risks. These accidents, in addition to human and environmental damage, impose high economic costs. Accordingly, risk identification in order to prevent losses and Unfavorable results of events are performed. Therefore, the health, safety and environmental hazards of the safety shoe industry were identified and evaluated.

This descriptive study was conducted, in 2020, in one of the safety shoe industries using Failure Modes and Effects Analysis technique (FMEA). The FMEA team was first formed to collect the required information, and then, the potential hazards were identified and recorded. Then, the Risk Priority Number (RPN) was obtained by multiplying the three factors of risk severity, occurrence and detection. Finally, modifications were proposed for unacceptable risks. All calculations were performed by Excel.

In 204 risks were identified 40 potential hazards with RPN from 108 to 300 and 164 potential hazards with RPN from 12 to 100 were identified. Gas with RPN= 300 and accumulation of explosive gases and vapors with RPN= 270 and electricity with RPN= 252 also inadequate lighting had the lowest RPN of 12.

The results of the present study show that FMEA is an appropriate method for identifying risks and assessing the risk of devices, equipment and machinery in the footwear industry that can identify and prioritize existing potential hazards.

Optimal lighting should create a balance between economy and the environment. In order to comply with safety and health principles of the staff, proper lighting of the work environment should be provided for everyday tasks. Inappropriate lighting conditions cause distortion of environmental visual information, and increase the likelihood of mistakes in the work. The quality of lighting is important for creating willingness to study, visual comfort, and productivity in the learning process of students. The subject of this research is the manner and intensity of lighting in schools, in the city of Bojnurd, in elementary education centers. It, also, tries to assess the quality of lighting schools, identify problems in school lighting systems, and provide appropriate solutions for improvement.

This descriptive study was randomly selected in girl’s elementary schools of Bojnourd, during autumn of 1395, in 10 schools in different regions of the city. The overall lighting (natural and artificial) and natural light were measured individually, using the Hanger CE Lux Meter. Collected data, including total brightness, natural, and artificial of classes, were analyzed by SPSS software (version 18). For each class, the minimum, maximum and average brightness and standard deviation were calculated based on the lux. Also, the type of lamps, defective lamps, wall colors and the quality of devices and equipment were studied.

Results showed that in 90% of cases, the intensity of lighting was consistent with standard values, and in 10% of cases, the lighting intensity was not in accordance with the standard. In 87.57% of the cases, the type of lamps was suitable for lighting of the school and classes, and in 94.1% of the cases the lamps were burned out and defective.

The lack of natural and artificial lighting in schools due to the incorrect placement of windows, inappropriate distribution of lamps, as well as the ratio of the surface to the window, are the causes of inappropriate status of lighting efficiency system.
