The purpose of this research is to investigate the impact of establishing a safety, health and environment management system on the performance of employees of the coking complex and refineries of Iranian Zarand Steel Company. Therefore, at first, the dimensions and issues of establishing the safety, health and environment management system and the performance of employees have been identified, and then the relationships between the identified variables have been presented.

To collect data related to the measurement of research variables, two standard questionnaires were used, which in total include 2 structures, 3 dimensions, and 20 questions. The content validity method was used to check the validity of the questionnaire. Cronbach's alpha coefficient was used to calculate the reliability and the reliability of the questionnaire was evaluated as very good. The statistical population of this research includes the employees and experts of Iranian Zarand Steel Company. After ensuring the validity and reliability of the designed scales based on the calculations, the questionnaires were distributed to a sample of 260 people. The structural equation model has been used to analyze the collected data and determine the relationships between the variables. Also, the analysis of the obtained data has been done using SPSS and SMART-PLS statistical software.

The establishment of the safety, health and environment management system has led to the improvement of systematic management in the organization, which is registered on occupational safety and health laws, and how it is implemented, even how to prepare and use personal protective equipment, is effective, and the process of work processes, empowerment and transforms employee collaboration; All this creates a wave that results in having skilled, creative employees with strong knowledge and excellent personal characteristics who will behave appropriately with both the customer and their colleagues.

 Emotional intelligence, as the ability to recognize and control one's emotions and feelings, is considered a new psychological approach to evaluating behavior in workplaces. Job stress, as an imbalance between job needs and individual abilities, has always been one of the main challenges of workplaces. Therefore, this research was conducted in one of the oil industries in Tehran to investigate the effect of employees' emotional intelligence on their job stress. 

  This research is a practical and analytical cross-sectional study. The population of this research, consisting of 300 employees, was selected by random stratified sampling. In this research, two questionnaires, Bar-On emotional intelligence, and HSE job stress were completed. Also, for data analysis, LISREL 8.72 and SPSS 18 software were used to estimate the causal effect between research variables and calculate descriptive indices as well as compare average variables.

 The employees' emotional intelligence and job stress had a significant inverse relationship; In other words, a higher level of emotional intelligence was associated with lower job stress. The subscales of responsibility and self-expression in the emotional intelligence test, and the subscales of relationship and role in the job stress test, had the highest and lowest numerical values in each test, respectively. Also, based on the results, employees' emotional intelligence levels and job stress were independent of their age and education level.

 Employees' emotional intelligence level affects their amount of job stress. Therefore, applying emotional intelligence skills in workplaces can significantly reduce the level of employees' job stress.

Cancer is often stigmatized in many societies and this has unfortunate consequences for sufferers. The aim of this research was to know the factors related to the social stigma of cancer.

The research method was correlation-analytical, and the sampling method was multi-stage cluster. Data were collected using CSI and CAM standard questionnaires.The statistical population included three categories of ordinary citizens, medical staff, and companions of patients in Tehran; Using Cochran's formula, the sample size was 384, 201, 384 people, respectively. In order to fit the model and measure the relationships between the variables, the method of structural equation modeling was used in the form of AMOS software.

 Goodness of fit indices (chi-square/df=2.851, Rmsea=0.08, Cfi=0.945) all indicated the appropriate fit of the model. Except for the variable of inequality in treatment, other independent variables had a significant relationship with stigma. The r2 explanatory coefficient showed that the variables of habitus, optimism, cancer awareness, religiosity, social support, and social capital together predicted 48% of stigma changes. Habitus and social support with standard coefficients (beta) of 0.48 and -0.28 had the highest and lowest contribution in explaining stigma, respectively. Based on the mean difference test, the amount of stigma among ordinary people was more than the other two groups.

 Awareness of different aspects of cancer disease (such as symptoms, causative factors), removing false stereotypes about cancer (such as cancer means death), constant communication with cancer patients, and receiving the necessary social support from various sources, were the most important tools necessary to reduce the stigma of cancer.

Health literacy plays a role in “reducing human casualties and financial costs” in a society. Emotional intelligence and media literacy also contribute to people’s success in life. Therefore, the aim of this study was to investigate the mediating role of media literacy in the relationship between emotional intelligence and health literacy among graduate students of Azarbaijan Shahid Madani University. 

This research is based on the nature and general characteristics, quantitative; Based on the purpose, it is applied and based on the research method and data collection method, is a descriptive correlation based on structural equation model. The statistical population was graduate students of Azarbaijan Shahid Madani University in 2020 (2218 students). The statistical sample of the research is 327 people who were selected by stratified random sampling method. To collect data, Emotional Intelligence Questionnaire (1998), Montazeri et al. Health Literacy Questionnaire (2014) and media literacy questionnaire were used. The reliability of the questionnaires was obtained using Cronbach’s alpha coefficient of 0.91, 0.84 and 0.79, respectively. The collected data were analyzed using descriptive statistics and inferential statistics (structural equation model) using SPSS and LISREL software. 

The findings showed the mean of emotional intelligence, health literacy and media literacy of graduate students of Azarbaijan Shahid Madani University is 3.10, 3.47 and 3.58, respectively. Also, the results showed a significant relationship between emotional intelligence and students’ health literacy. According to the findings, there is a significant relationship between emotional intelligence with media literacy, and media literacy with health literacy. Also, the media literacy variable plays a mediating role in the relationship between emotional intelligence and health literacy (coefficient) of 0.58 units. The results of the structural equation model test also showed that the proposed conceptual model fits the relationship between emotional intelligence, health literacy and students’ media literacy. 

Media literacy can not only directly affect students’ health literacy, but also has a mediating role between emotional intelligence and health literacy. Due to the effect of emotional intelligence on students’ health and media literacy, it is recommended that the necessary planning to be done in graduate education and to strengthen emotional intelligence.

 The aim of the present study was to assess factors affecting behavioural management of dental anxiety among dental students.

 The present study was conducted on 218 dental students of Ahvaz Jundishapur University of Medical Sciences, Ahvaz (AJUMS), school of dentistry, Iran during 1 to 21 November 2020. The data collection tool included a self-designed questionnaire containing a number of questions for assessing students’ anxiety reduction guidelines, and behavioural-medication anxiety control methods, as well as measuring key components of the Theory of Planned Behaviour (TPB). The layout of the questionnaire and all its questions/items were designed on the website https://survey.porsline.ir. Data were analysed using SPSS, version 23. The structural equation modelling (SEM) was performed using AMOS software version 26.0.

 A total of 246 dentistry students were invited to participate in the study. Out of 246 students enrolled, 218 (88%) students completed and sent the questionnaire. The results revealed that behavioural intention had a direct impact on the implementation of distinguished instructions. Likewise, subjective norms and perceived behavioural control directly influenced the behavioural intention. The fit indices indicated that the measurement might have an acceptable performance (GFI = 0.86, CFI=0.81 RMSEA = 0.07, x2/df >3); R2=0.37. Perceive behavioral control and intention were the most important factors in explaining dental anxiety control behaviour.

 The findings suggest that the constructs of the theory of planned behaviour might have a preliminary acceptable fit for determining the factors related to the beliefs and behaviours of dental anxiety control. Further studies are needed to improve model fit indices. The future studies should determine which educational methods could better manipulate the predictive factors.

Unit risk management is a critical component of gas refining management, as risks that are not well-managed may lead to trip production failures. The present study aimed to provide a structural model for investigating the role and effect of different variables on stopping the gas production process in the gas refinery.

This study was a retrospective cross-sectional and systematic analysis, which was carried out on key risks in the trip gas sweetening unit in a gas refinery industry located in Asaluyeh, Iran. The systems analysis was applied by using Fishbone Diagram, and then data modeling was prepared by Structural Equation Modeling (SEM) for an incident that occurred during gas sweetening production. Tools for the data analysis included the SPSS 24 and Smart PLS 2 software.

Results of this research indicate that “Environment Risk” with a path coefficient of 0.943 and T- Value of 103.791; “Cost Risk” with a path coefficient of 0.937 and T- Value of 95.168; “Implementation of management system Risk” with a path coefficient of 0.847 and T- Value of 35.23; “Accident Risk” with path coefficient of 0.577 and T- Value of 25.410; “Time Risk” with path coefficient of 0.758 and T- Value of 15.121; “Human Error Risk” with path coefficient of 0.712 and T- Value of 11.215 had the most important coefficients of the paths respectively, that are effective in stopping production concerning other risks. Also, by comparing the path coefficients of the risks we can see that the impact of each of the risks on stopping production is different.

The findings of the present study revealed that a combination of variables can affect stopping production in the gas industry. Therefore, the role of these risks in losses in the refinery system should be investigated.

Since achieving the goals of the organization requires serious will and commitment of employees to the organization and research related to organizational commitment and its sub-components has attracted the global attention So ,It is necessary to find antecedents and mediators affecting the commitment of employees, especially in medical centers. Therefore, the aim of this study was to determine the mediating role of organizational justice in the relationship between mentoring functions and organizational commitment in hospital staff.

This is a correlational study based on structural equation modeling. The statistical population of the study consisted of all staff of Poursina Hospital in Rasht. 403 employees were selected by quota sampling method. The selected samples answered the Mentoring Function Questionnaire, Organizational Justice Questionnaire and Organizational Commitment Questionnaire. Data analysis was performed using Pearson correlation coefficient and structural equation modeling through SPSS and AMOS. To analyze the mediating relationships, the Bootstrap method with Preacher and Hayes' Macro (2008) program was used.

Fit indicators showed that the proposed mediation model has a good fit with the data and its functions and subscales have a positive and direct effect on organizational commitment . Results show that there is positive and significant relationship between mentoring functions and organizational commitment (p<0.01,r=0.276) also ,between mentoring and organizational justice respectively (p<0.01,r=0.711).in this regards,between organizational justice and organizational commitment,there is positive and significant relationship(p<0.01,r=0.305). findings indicate that organizational justice has immediate role between mentoring function  and organizational commitment.

According to the research results, guidance has a significant effect on organizational justice and organizational commitment of employees. In addition, organizational justice and its subscales mediate the role of guidance and organizational commitment of employees. Therefore, in order to increasing commitment and improving organizational justice in hospitals, special attention to mentoring dimensions is suggested.

Covid-19 pandemic peak put additional strains on healthcare system. In this crisis, the resilience of nursing staff is critical. This study aimed to investigate the relationship between burnout and resilience in frontline nursing staff working in high-risk areas during the outbreak of Covid-19 pandemic.

The present study is a Descriptive-analytical survey, and the target group is Iranian nurses. According to the Ministry of Health statistics, 125369 people are participated in this study. information is collected from 384 people by cluster distribution using questionnaire. The statistical analysis in this study is performed by SPSS and SMART-PLS software

According to the study, all the collected information is normal. Based on factor analysis, there is an inverse significant relationship between resilience and burnout, and also, the sense of success has a significant effect on resilience as part of burnout.

In order to increase the resilience of nursing staff in such conditions, it is necessary to pay more attention to the factors affecting their burnout and plan to minimize it. Developing educational programs and adding diversity in service delivery might be useful to enhance personal feelings and also reduce burnout.

As shown in many studies, one of the most important reasons for headaches in individuals is their tendency to self-criticism. Discovering some protective factors in order to moderate this tendency, thus, can be one of the important goals of health psychology research. Therefore, the current study aimed at investigating the relationship between self-compassion and self-criticism in women suffering from tension headaches using structural equation modeling.

To do so, 110 women with tension-type headaches were selected through purposeful sampling from psychiatric and neurological clinics and specialized headache centers in Isfahan, and were asked to respond to self-compassion and self-criticism questionnaires. The collected data were analyzed using the structural equation modeling (SEM) on Amos and SPSS software programs.

The results revealed that the presented model fitted the data well. There were negative relationships between positive components of self-compassion (self-kindness, common human humanity, and mindfulness) and self-criticism. On the other hand, there were positive relationships between the negative components of self-compassion (self-judgment, isolation, and over-identification) and self-criticism. The findings showed the research model was appropriately presented.

Conclusions‌:

 Therefore, based on the results obtained from the present research, it can be concluded that self-compassion as a protective factor can have a significant impact on self-criticism in women with tension-type headaches.

In the third millennium, aging and elderly has become more and more a major global reality. One of the effective factors of human health, especially in old age, is exercise. The current research intended to identify the influential factors on enhancing the elderly sports participation in the framework of a model.

It was a mixed-method (Qualitative, quantitative) research. In the qualitative section, 17 teachers and sports experts were interviewed purposefully, and accordingly, 10 influential factors enhancing the elderly sports. With respects to the quantitative section, based on convenience sampling, 324 elderly people responded to a questionnaire, both online and non-online. The validity of the questionnaire was accounted for based on experts’ views and confirmation and the reliability was done based on Alpha Cronbach, which amounted to be 95%.  The exploratory factor analysis also affirmed the researcher-made questionnaire.

The structural equation analysis test of the proposed model illustrated that, except for the cultural and reputation factors, all other factors would leave a significant and influential impact on the elderly sports (p<0.01). Were 10 factors identified, including medical, entertainment, physical fitness, cultural, environmental, facility, social, advertising, health, reputation, and financial factors. Meanwhile, the most influential factor was health, with the record of 40 percent.

Paying attention to the effective factors in increasing the sports participation of the elderly will promote health in various aspects of the elderlychr('39')s life. This will facilitate and improve the quality of nursing care for the elderly. Officials and managers are encouraged to consider the priorities identified in this study and to make the necessary investments and planning so that seniors can design more exercise programs to survive.

Global demand for halal food products is growing. Arab countries have taken the initiative as the global center of halal food. Halal food consumers are currently most concerned about the integrity of the halal status and curiosity about all activities involved throughout the supply chain so that the products purchased are genuine throughout the halal production path. Halal food management is likened to a supply chain from an organizational perspective. Although halal honesty is widely found in halal industrial publications, the factors affecting the integration of halal food supply chain and comprehensive research on halal food supply chain and safety have not been discussed in Iranian journals to date.

We propose a conceptual model to study the dimensions of the halal food supply chain and the relationship between the implementation of the halal food supply chain and managerial performance in order to assess the safety and quality control and assurance of halal food. A total of organizational information from 240 different countries was used in this study. For this purpose, structural equation modeling (SEM) was used.

The results showed that the implementation of halal food supply chain can affect food safety. In general, these findings indicate the need for strategic evaluation in ten dimensions of halal food supply chain.

Transprancy in the supply chain puts the risk of producing insoluble products at risks reduces all stages of product production and this designand can be used as a reference model by manufacturers in the halal food industry.

The development of health among different sections of society is the main concern of researchers in todaychr('39')s world. In this regard, it is one of the useful ways to develop the health of sports and physical activity. So that physical activity causes psychological and social development of young people and the elderly, personal growth and development. Finally, those who exercise have a higher quality of life than non-athletes, and through exercise, knowledge of nutrition, exercise and health can be developed. For this reason, over the years, the role of exercise and physical activity in society has become increasingly important not only for the individual but also for public health. What is vital and very important in this regard is the issue of continuing physical activity and exercise, because maintaining health benefits requires continuous participation in physical activity and sports. In this regard, research has shown that regular physical activity and exercise provide numerous health benefits. However, the benefits of physical activity and exercise are not achieved by cross-sectional, occasional, and sporadic presence, although having minimal physical activity is better than no physical activity at all. To this end, physical activity guidelines recently recommend regular and continuous participation in physical activity. However, in all parts of the world, a large number of people in the community have not yet taken the impact of physical activity and sports seriously. For this reason, different countries are trying to adopt solutions to combat inactivity, as well as to encourage people to participate regularly and continuously in physical activity and sports and to gain health, vitality and vitality. One of these approaches is public sports or sports for all, which tries to create equal opportunities for people with any cultural, racial, economic, gender or other differences to participate in cheap and fun sports activities. Public sport is necessarily a philosophy, a message to motivate citizens to participate in sports and ultimately health. The tendency of people towards public sports and its positive effect on the physical and mental health of managers and officials leads them to study methods that increase the number of participants in public sports. Certainly, the coherent view of these groups will lead to progress in this regard; As these perspectives differ, the lack of coordination between the perspectives challenges the planning work for the development of grassroots sports. Therefore, it is necessary to coordinate between policy makers and planners in each country.

The present study is a descriptive-correlational study that was conducted with the structural equation model approach. The statistical population of this study included 354 people including the Director General of Sports and Youth of Khuzestan Province, Deputy Chiefs of Staff of the General Directorate, Deputy of Women Affairs of the General Directorate, Heads of Sports Departments of the General Directorate, Sports Experts of the General Directorate, Heads of Sports Boards, Vice Chairman of Sports Boards, Secretaries of Sports Boards And sports management experts in Khuzestan province. According to Schumacher and Lumex, for structural modeling equation studies, the minimum sample size is 200 to 600 people. Given that there were no questionnaires or standard scales for measuring research variables, the researcher reviewed the sources and documents and articles related to the research topic; Also, asking for opinions from professors, experts and managers of physical education and sports in the country, a researcher-made questionnaire was prepared, which included 56 questions and a five-point Likert scale. This questionnaire consisted of two main parts: personal information and managerial background. After analyzing the questions of the researcher-made questionnaire using tests of degree of difficulty, discrimination coefficient and loop method, we used exploratory and confirmatory factor analysis to determine the validity of this questionnaire. Descriptive statistics (frequency, frequency percentage, mean and standard deviation), skewness and elongation test were used to evaluate the normality of the data and the measurement model was used to evaluate each of the factors affecting the development of public sports to promote health as inferential statistics. All analyzes were performed at 95% confidence level using SPSS 19 and AMOS 22 software.

The results of the present study showed that the managerial factor with a factor load of 0.743, the resource factor with a factor load of 0.761, the behavioral factor with a factor load of 0.716 and the environmental factor with a factor load of 0.785 have effect on health development.  In addition, the hypothetical model of research on health development in Khuzestan province with a public sports approach has a favorable fit. The results of the research showed that the environmental factor of public sports was the most important factor in the development of health in Khuzestan province, followed by resource, managerial and behavioral factors, respectively. Each factor or variable in institutionalizing an action or behavior has three functions: regulatory, normative, and cognitive functions. Regulatory factors seem to be an important and fundamental behavior in the early stages of institutionalization. Because public sports in the country is at the beginning of its path and is not so developed, it requires more structure and framework for expansion and development. Therefore, environmental factors can cause the structuring and framing of public sports and ultimately institutionalize health and vitality in society, because it seems that the regulatory function of environmental factors is greater than other functions.

In general, the results of this study show that public sports is one of the factors affecting the level of health in Khuzestan province and public sports is also affected by managerial factors with managerial, resource, behavioral and environmental subscales. The role of behavioral factors in institutionalizing health behavior in public sports is very important and fundamental, because these factors provide the ground for acceptance and continuation of physical activity and sports behavior in individuals. However, a set of behavioral factors were ranked last in the factors affecting the institutionalization of health through public sports in Khuzestan province. Perhaps the reason is that the functioning and effectiveness of behavioral factors depend on the good performance of other factors, and until other factors do not work well, these factors can not have a good performance and impact, therefore, in terms of respondents are in the last place. Such a priority seems logical since public sports are in the early stages of formation and growth and requires focusing on other factors, especially environmental factors to shape and frame public sports in society. This is because the proper functioning of the set of environmental factors may results in structuring and framing of the public sports. In addition, resource and managerial factors play an important role in promoting and properly guiding environmental factors. It is possible that the respondents are of the opinion that first public sports will find a special place, structure and system in Khuzestan province and then its institutionalization in the existence of each individual in the society will be on the agenda. This framework can institutionalize public sports as an activity. Facilitate a body that promotes health and vitality in the existence of each individual in the society.

According to the important role of the psychological variables on students various dimensions of health and academic performance, The purpose of the present study was to Compilation of causal model of the relationship between academic perfectionism and academic proclivity of medical students with the role of mediation of emotional self-awareness. Correlation research method was structural equation model. The statistical population of the study consisted of all female students of Medical science University of Kermanshah in the academic year of 215-16, among which 140 were selected as sample size. The instruments used in this study included Identity and Felt Educational Perfectionism Questionnaire (1991), Solomon and Root Blum (1984) and Scholar Enrollment Questionnaire Franklin and Longford (2002). For data analysis, structural modeling and partial least squares algorithm (PLS) and software (SPSS) were used. Instruments were worthy of reliability and reliability. In data analysis, structural equation modeling was used to study the causal model between variables. The findings showed that academic perfectionism directly affects academic proclivity and emotional self-awareness. Also, emotional self-awareness has a negative and significant relationship with academic procrastination. The value (GOF=0/44) indicates a general and robust fit of the research model, which suggests fitting the data with the proposed research model. According to the findings of this study, it can be said that educational perfectionism has an effect on academic proclivity and emotional self-awareness of students. And the need for more educational authorities to pay attention to the importance of discussions and psychological interventions and counseling in improving their performance and improving the health of their students.
 

Occupational  concerns such as inadequate staff numbers, high workloads, long working hours and work strain make nurses fail to play their role in their families.

Teaching evaluation by university students is one of essential and controversial processes in higher education. The core of debates over student evaluation of professors is the possibility of interference of factors irrelevant to professor’s teaching skills and capabilities. The main purpose of this research was to explore the confounding variables in teaching evaluation by students.
This paper was a descriptive correlational study which employed structural equation modeling. The population included all BSc students of paramedics'' faculties studying in the second semester of 2013-2014 academic year in Iran University of Medical Sciences. A number of 250 participants were selected through cluster sampling. The data collection tool was Ghazi Tabataei and Yousefi’s questionnaire modeled after Marks¡ Paswan¡ and Young with a five point Likert scale and 31 items. It measured six factors related to student evaluation of teaching. The data were analyzed by means of structural equation modeling technique.
A number of 215 questionnaires were analyzed. The findings showed that professor-student interpersonal relationship¡ students'' interest in the course¡ and professors'' effort and involvement had a positive correlation with student evaluation¡ and course difficulty¡ dissatisfaction with the scores and the difficulty of assignments had a negative correlation with student evaluation of the professor.
The results showed that confounding and sometimes confusing factors may affect student evaluation of teaching and cause false judgments or decisions.
