Considering the importance of maintaining the energy and health of the staff and faculty members as human beings, organizational conflict can have a significant impact on public health, performance, and the rate of depression in these individuals. The aim of this study was to investigate the relationship between job performance and depression with organizational conflicts in professors and staff of Larestan University of Medical Sciences.

This descriptive-analytical cross-sectional study was conducted in 2016 on 82 professors and staff of Larestan University of Medical Sciences  selected by census sampling method. In order to collect information in the present study, three questionnaires (organizational conflict, job performance, and Goldberg depression) were used.

The mean of depression was 58.20 with a standard deviation of 17.16, the mean of job performance was 30.55 with a standard deviation of 27.5, and the mean of organizational conflict was 93.20 with a standard deviation of 42.5. Conflict with subordinate had a higher mean score and conflict with peers had a lower mean score. The frequency distribution of depression among the participants showed that healthy individuals had the highest frequency (27.7%) and individuals with severe depression had the lowest frequency (4.8%).

The findings showed an inverse relationship between depression and job performance, but a direct relationship was observed between depression and organizational conflict. By identifying and modifying the causes of stress in the workplace, we can see the improvement of performance and the creation of desirable and efficient feelings in medical personnel.

Hospitals are working to create innovation in patient care throughout the world while maintaining high quality standards. Since in implementing this innovation, hospitals have an impact on the natural environment, hospital managers are constantly developing management plans to conserve energy and dispose medical waste properly to reduce the damage to patients, surrounding communities, and the natural environment. Therefore, this study evaluated the important and effective indicators in order to target the measures in the field of hospital environmental management.

This cross-sectional analysis was designed and implemented in 2018 and 2019 in Trita subspecialty hospital in the west of Tehran. To implement this study, ISO 14001 standard was used and ISO 14031 standard was applied to monitor it.

According to the findings, 18 important and basic indicators were defined in the field of environmental performance for the hospital and the relevant indicators were measured. Correction and improvement of indicators was clearly observed in 2018 and 2019. Most of the corrective actions and the most noticeable changes were related to waste.

The use of environmental assessment models along with managerial support for corrective action can protect the environment in the long run and improve public health. Moreover, proper management of the hospital waste can reduce the costs.

Today, accident investigation and analysis is an important component of safety programs in preventive measures. Incident investigation involves collecting all the information and actual interpretations of an incident, analyzing information to find out the causes of the incident, and writing an incident report.

This descriptive-analytical article was conducted to determine the most important criteria for investigating and selecting the techniques of accident investigation as well as analyzing and selecting the best method of accident analysis in the events of the power plant industry. In this research, previous research studies were studied and expert opinions were collected with regard to the most important criteria for choosing a specific accident analysis method. Later,  the 4 accident analysis methods was applied in a special power plant accident and the decision matrix was designed based on the strengths and weaknesses of the model formation. Finally, these four methods were prioritized using the Topsis decision-making method.
The key factors in investigating the main criteria for selecting an incident analysis method  included the ability to understand the sequence of events in the model, identifying the root causes, descriptiveness and ability to provide reasons for managers and specialists, the need for technical experts, and the time criterion. The TRIPOD BETA method was selected as the best method for analyzing the power accidents.

The TRIPOD BETA method was introduced as the most effective method for investigating power plant accidents.

As with other occupations, mistakes and unsafe behaviors are among the major causes of accidents in sports. Given the harmful consequences of sport accidents, it is essential to identify ways to control and reduce these unsafe practices. Therefore, the purpose of this study was to develop a strategy to prevent the effects of unsafe practices on the occurrence of sports accidents in sports environments.

The research was fundamental in terms of purpose and qualitative data were collected using grounded theory using a Glaser approach. The study was conducted among 20 experts in the fields of safety, occupational medicine, psychology, sports injuries, and sports management in 2020. The participants were selected to attend in-depth unstructured interviews purposefully based on the snowball method. Data were analyzed simultaneously using a set of open, selective, and theoretical coding.

The results indicated that the four factors of individual, organization, job knowledge, and the relationship between individual and organization were the main causes of human error in the occurrence of sports accidents. The individual and organizational variables (as process variables) and job knowledge as well as the relationship between the individual and the organizational factors as developmental and auxiliary variables played teh major role in this field.

According to the causes of sport accidents, improving the personal attitude and performance, improving the organizational structure, continuous learning and training of job knowledge, as well as improving and strengthening the positive relationship between the individual and the organization can reduce the risk and promote safety. However, lack of  paying attention to these factors disrupts immunity.

Mental workload is one of the effective factors on the performance and efficiency of people working in an organization that put their health at risk. The aim of this study was to determine the mental workload of staffa working in a bank in Hamadan City of Iran  by NASA-TLX method.

In this cross-sectional study, 110 bank employees were surveyed. The data were collected using demographic and NASA-TLX questionnaires. Finally, collected data were analyzed using SPSS version 21 by running descriptive statistics and statistical tests.

According to the participants, the mean and standard deviation of effort and mental demand, as the most important dimensions were 81.04 ± 14.51 and 79.50 ± 18.05, respectively. The performance dimension was selected as the least important dimension with the mean and standard deviation of 64.37 ± 10.17. The results of statistical analysis showed no significant relationship between the participantschr('39') total score of mental workload and their demographic information such as age, gender, educational level, marital status, experience, and work overtime(P>0.05). The Pearson correlation coefficient showed that age (P<0.05) and work experience (P<0.01) had a significant and inverse relationship with temporal demand dimension .

Based on the findings, the mean of perceived mental workload of bank employees was high. Therefore, effective programs should be conducted to mitigate and reduce the mental workload and to promote mental health of bank employees.

Fatigue is defined as extreme weakness and exhaustion by work and physical or mental effort. Sleep disturbances are among the most important causes of fatigue among people in various occupational societies. The aim of this study was to determine the relationship of occupational fatigue with sleep quality and factors affecting it among nurses working in governmental hospitals.

This cross-sectional study was conducted on 240 nurses working in public hospitals selected by convenience sampling method during a two-month period. In order to collect data, the Fatigue Exhaustion / Fatigue Recovery Questionnaire (OFER-15) and the Pittsburgh Sleep Quality Questionnaire (PSQI-18) were administered. The data were analyzed using SPSS software version 16. Furthermore, Chi-Square, Spearman’s correlation, Independent Sample T-test, and one–way analysis of variance were run.

In this study, 55% and 70% of the participants were at inappropriate sleep quality status and the moderate level of occupational excessive fatigue, respectively. Spearman’s correlation test showed a direct and significant correlation between occupational excessive fatigue and sleep quality (p<0.5).

Given the significant correlation between sleep quality and fatigue in this research, sleep quality can be used as a predictive variable of excessive occupational fatigue.

Risk-based inspection is a powerful tool provided by the American Petroleum Institute in order to respond to the needs of the process industries. The main focus of this method is on inspection, integrity management, maintenance, as well as reduction of the probability of failure. The purpose of this study was to conduct the risk-based inspection technique and critical success factors in its implementation to improve risk and process safety based management systems.

In this review study, we first listed the keywords based on the research title including Critical Success Factors, risk assessment, process safety, corrosion management, inspection Plan, failure mechanism, Risk Based Inspection, Risk Based Maintenance, Risk-based Integrity Management, and Asset Integrity Management . Later, each term was searched specifically and without time limit in the internal and external databases of Science Direct, PubMed, Google Scholar, SID, Google Search, Magiran, Civilica, and Scopus.

A systematic review of various studies showed that critical success factors provided the necessary context for the implementation of a risk-based inspection process in the process industries and were essential factors for the effective implementation of the RBI method.

By analyzing the results of the studies we found  that identifying CSFs can improve the effective implementation of RBI in industries and guarantee the benefits mentioned for this method. Moreover, the engineering and accurate implementation of risk-based inspection method will lead to the best implementation of management systems based on the risk and process safety and its improvement.

Abstract  

Today, the employee productivity is a crucial topic to achieve the organization goals. In this regard, considering the organizational health and employee depression by managers is an important issue in organizational productivity. So, the purpose of this study was to investigate the relationship between organizational health and depression with the productivity of employees of sports and youth departments in Isfahan province and to present a structural equation model.

In this descriptive-analytical study, a partial least squares approach was applied for modeling. The research instruments were Hershey and Goldsmith (1980) Productivity Questionnaire, Hui and Fieldman (1996) Organizational Health Questionnaire, and Beck Depression Inventory (1961). Validity of the questionnaire was confirmed by experts and the reliability of the questionnaires was appropriate. The statistical population included employees of the sports and youth departments of Isfahan province (387 people). The statistical sample size was calculated based on the number of research factors based on the PL approach. As a result, 90 people were appointed and 78 complete questionnaires were collected and returned. Cluster random sampling method was used.

The results showed that organizational health had a positive and significant effect on job productivity (p /0 0.01), but depression had a negative effect on job productivity that was not significant. Depression also had a negative effect on organizational health, but this effect was not significant.

The ability of the organization to maintain and improve organizational stability and improve this ability leads to improving the productivity of employees of sports and youth departments. In this regard, it is suggested that managers and supervisors of sports organizations
emphasize the importance of communication with and among employees to improve organizational health and emphasize organizational psychological issues to improve productivity
