Research shows that there is a relationship between religion and spirituality with social behavior and mental health. Among the different religions, Muslims have the largest number in the world. Muslims pray five times a day.

The purpose of this study was to review previous findings on the effect of Salat (Muslim prayer) on the mental and psychological health of people.

More than 50 articles were reviewed and finally the most relevant articles were separated and analyzed.

The results indicate that there is a direct relationship between Salat and increasing the desire to live, hope, endurance of hardship, feeling happy and happiness, hope for recovery in patients. Also, prayer has an inverse relationship with anxiety and depression, despair, despair, dissatisfaction with life, discomfort with illness and problems.

According to these findings, doctors and researchers in the health sector are expected to conduct new studies without religious and belief bias in order to understand and improve the mental and psychological conditions of patients, so that the mechanisms involved in these positive effects are revealed and possibly insight new in the process of improving people's mental and psychological conditions.

The present study was conducted with the aim of investigating the effect of six weeks of intermittent exercise and curcumin consumption on BMP2 gene expression in the vascular smooth muscle of male Wistar rats. In an experimental trial, 30 male Wistar rats were randomly divided into six groups (5 rats in each group): control, diabetic, healthy intermittent exercise, intermittent exercise diabetes, curcumin diabetes and curcumin exercise diabetes. Diabetes was induced by intraperitoneal injection of streptozotocin poison (50 mg/kg). Intermittent training consisted of 5-12 bouts of intense work (75 to 100% of maximum speed) of 60 seconds with active rest intervals of 75 seconds, six days a week for six weeks. Curcumin was fed to animals by gavage at a dose of 50 mg per kilogram of body weight. After six weeks, unconscious animals and blood samples were collected from their hearts. The data were analyzed using ANOVA statistical test and Benferroni post hoc test. Induction of diabetes increased BMP2 gene expression in vascular smooth muscle of male rats. Intermittent training decreased BMP2 gene expression in vascular smooth muscle of diabetic rats. Six weeks of curcumin consumption reduced the expression of BMP2 gene in vascular smooth muscle of diabetic rats. In general, the results of the present study showed that intermittent exercise and curcumin improve diabetes disorders caused by BMP2 gene expression and calcification and its complications.

Physical activity affects the health of the body's organs through several processes. Apoptosis is one of the important cellular processes that play a role in maintaining the balance between cell death and tissue growth. The aim of the present study was to examine the previous findings regarding the effect of physical activity and exercise on apoptosis in order to obtain a relatively comprehensive knowledge of this effect by summarizing and analyzing the data. To collect the information of the articles, a search was made from PubMed, MEDLINE, SID, IranMedex, IranDoc, Magiran and Medlib databases. More than 80 scientific articles from 2000 to 2023 were reviewed. The keywords used were: physical activity, aerobic exercise, endurance exercise, apoptosis and cell suicide. After the review, finally 26 articles were selected. Then, the selected items were fully studied and finalized, and the items that were more complete than the others were selected as references. Physical activity and exercise, especially aerobic exercise, as a safe, cheap and accessible method, can reduce apoptosis through several mechanisms. The breadth of studies in this field, and the overlapping of many data, allows us to confidently introduce exercise and aerobic activity as one of the best methods of regulating body homeostasis and reducing apoptosis.

Today, attracting and retaining loyal customers is a requirement for success in the field of competition for organizations. The result of all marketing mix activities is a set of controllable marketing tools that respond to the target market. The quick and accurate identification of customers' behavior and their arrangement in the categories of Promoters, Passives and Detractors helps managers to take timely actions according to the feedback of customers. In this research, while identifying the most important marketing mix criteria, the evaluation and arrangement of customers of a chain store is discussed using the new OPLO-POCOD SORT technique.

This technique is one of the quantitative techniques in the field of multi-criteria decision-making. By collecting the opinions of customers and evaluating them, an attempt has been made to sorting customers into profiles and reference options of Promoters, Passives and Detractors.

This research was conducted in the form of a case study of one of the chain stores in Shahrood and by evaluating the opinions of 20 customers. In order to quickly evaluate and sort the customers based on the technique used, the customers are placed in three strategic categories of Promoters, Passives and Detractors, and due to the negative effect of the Net Promoter Score by -0.25, fundamental reforms are needed.

Based on the results of this research, managers can use the proposed technique of quick evaluation of customers and their classification, to carry out the process of necessary measures to maintain Promoters customers and reduce dissatisfied and Detractors customers.

A large amount of Municipal Solid Waste (MSW) is daily produced by residential places and commercial activities which is a major threat to modern societies. The sustainable management of solid waste is one of the most important urban management challenges that should simultaneously take into account the economic, environmental, and social criteria related to waste recycling.

In this study, utility assessment of paper recycling technologies based on sustainability criteria was examined as a multi-criteria decision-making problem. Accordingly, the fuzzy Vikor method was used to rank the recycling technologies, and then the UTASTAR method was utilized to measure the utility of the selected options.

As a result, this study led to a final utility criterion for each of the paper recycling technologies that facilitates their quantitative comparison in terms of sustainable development.

Finally, anaerobic digester technology was selected as the best paper recycling technology with the highest score in the fuzzy Vikor rankings and the highest added utility based on the UTASTAR method.

Despite the proving of the negative effects of dehydration, many athletes use of this strategy yet. The aim of this study was to investigate the effect of dehydration with different degrees on serum levels of enzymes biomarker muscle damage in professional wrestlers in Ahvaz city. Among the professional wrestlers in Ahvaz city, after screening, 40 wrestlers were selected and randomly divided into three experimental groups and one control group. Experimental groups underwent dehydration at three levels of mild, moderate and severe. The plasma levels of Creatine Kinase (CK) and Lactate Dehydrogenase (LDH) were measured by enzyme kinetics method. for intragroup comparison and intergroup comparison, were used of the dependent t-test and analysis of variance (ANOVA) test respectively at a significance level of 0.05. The results showed that plasma CK levels increased significantly in the moderate and severe dehydration groups and LDH levels increased only in the severe dehydration group (P <0.05). Also, in the intergroup comparison of CK levels, it was observed that there was a significant difference between the severe dehydration group and other groups, as well as the moderate dehydration group and other groups (P <0.05). But no significant difference was observed between the moderate and severe dehydration groups (P <0.05). Also, the results of comparison between groups of LDH showed that only the difference between the severe dehydration group with other groups was significant (P <0.05) and the difference between the other groups was not significant (P <0.05). According to the results of this study, it is suggested that to prevent the possibility of muscle damage and consequently reduced the exercise performance, avoided the dehydration of more than 1% in one session and if necessary, dehydrate in more sessions and for longer.

The purpose of this study was to design and evaluate a human resources performance evaluation system of the Ministry of Sports and Youth according to axioms based technique. The research method is an exploratory mixed based on the design of a questionnaire using the principle of the axiom design technique. The statistical population of the survey is formed by all human resources of the ministry(including managers, employees and experts) for the year 2017(N=960)where 274 samples were considered(n=274)based on Kerejsay and Morgan table. Data gathering tool is a researcher-made questionnaire which is based on human resource performance evaluation. For analyzing the data in the design field, an axiom-based technique as well as inferential statistics including a structural equation model or multivariate analysis with non-variable variables were used. Also, apparent validity was determined according to ten people and construct validity using factor analysis. On the other hand, reliability of the questionnaires was calculated based on Cronbach's alpha (α= 0/75). The results of this study showed that the three factors of employee selection, human resources performance indicators, staff retention and their underlying factors are appropriate for designing and assessing the human resources performance evaluation system of the Ministry of Sports and Youth. Also, none of the questions of these components were excluded from the research model, therefore, according to the results of the research, the ministry should be able to identify areas of the performance appraisal system and help identify opportunities and limitations.

This study investigated the criteria influential in determining the construction site of the urban solid waste recycling centers and then determined the importance of each of these indicators. Then, in order to evaluate and rank the candidate locations, a new method based on the Multi Mora technique was introduced.

This descriptive survey is an applied study in terms of its purpose. As such, the required data were collected through a questionnaire. In the first phase, the potential indicators were identified in a library research. Moreover, to determine the weight of the indicators and score the items, the opinions of 14 experts in the field including the relevant executive managers and university instructors were sought.

The results of the study revealed that the three indicators of construction cost, current land cover, and soil cover were the most important ones playing a key role in determining the location of the recycling centers. After the potential locations were evaluated in District 22 of Tehran Municipality as a case study, three places which scored the highest were identified as the optimal recycling stations.

The criteria for locating waste recycling centers are dynamic in nature, and both their nature and weight along with the importance of each of them change over time. To this end, for each new case, relevant managers and officials should consider new indicators, including costs and other new issues, when deciding on a construction site for recycling centers.

In recent years, road accidents have become one of the leading causes of death in Iran. Due to the role of various factors in the occurrence of a road accident, the management of the occurrence of this phenomenon has been associated with many challenges.Due to the presence of several qualitative and quantitative factors in the accident analysis process, this research uses a developed approach based on the theory of Rough Sets to identify the pattern of road accident incidence. By using the proposed model, it will be possible to analyze the occurrence of accidents in multiple dimensions and finally rule out an accident by combining the factors involved. For this purpose, a comprehensive range of factors based on the literature of the subject and the opinions of experts related to the vehicle, driver and the intended environment are discussed. Key findings of the accident management research suggest that the existence of scientific models of accident factors can reduce the number of road accidents. The causes of the accident with the highest number of repetitions were extracted in the form of rules.  The results show that the type of accident depending on the type of vehicle and the weather conditions can have different severity of the accident. In addition, the cause of an accident under various conditions, such as atmospheric conditions, can have a specific incident severity. Thus, the theory of Rough sets performs an acceptable function in analyzing the role of accident factors and its quality in order to respond appropriately after occurrence and prevention.

Semnan province, due to its diverse climatic conditions, being bordered by Mazandaran province and having ecological landscapes and historical and tourist attractions, has busy rural roads that are sensitive to the problem of road accidents; Therefore, the need for research and investment in rural infrastructure in Semnan province to improve the safety of these essential roads. set. Using Ruff set theory, this research allows researchers to analyze accidents in multiple dimensions and regulate the occurrence of an accident by combining the factors involved. The purpose of this study is to identify accident-causing patterns and use these patterns in the management of related factors to consider eliminating or reducing the causes of accidents in their operational plans. Using the proposed model, it will be possible to analyze the incidence of accidents in multiple dimensions and finally, the occurrence of an accident by combining the factors involved in it will be regular. For this purpose, a comprehensive range of factors based on the literature and opinions of experts related to the car, driver and environment will be considered. Then, the collected data on the quality of rural road accidents in Semnan province will be studied. 

Deming cycle is one of common terms in continuous improvement that many researchers have studied it, based on the cycle organizations should go through different stages to get continuous improvement. Managers as main stimulators of the cycle according to their capabilities can move the cycle at different speeds, from static mode to continuous circulation. In this regard, the study was conducted with the aim of developing a process model based on data envelopment analysis (DEA) to evaluate the behavioral performance of 20 higher education institutions in North Khorasan province. One of the innovations of this research is the classification of higher education institutions in different stages of the Deming cycle into program-oriented, action-oriented, control-oriented and feedback-oriented (result-oriented) institutions. The results of this research, in addition to determining the efficiency of each higher education institution, can provide a virtual organization as a basis for management in the life cycle of Deming. In data envelopment analysis, for each of the inefficient units, a number of efficient units are determined as a reference with a coefficient. For example, in order for an educational institution to be able to Benchmark its planning process from efficient organizations, DEA proposes JD organizations with Coefficient of 0.13 and an RS organization with Coefficient of 3.0.

Purpose - To promote knowledge about how the process of change and its performance is implemented, and the complex environment in which public organizations operate. Methodology - The combination of three government offices in Mashhad was selected for a case study. This integration was carried out in an environment increasingly complicated by the progressive development of implementing the process. The main method of collecting data was interviewing managers who participated in organizational change. A total of 19 interviews were conducted. Interviews were coded using Atlas.ti software. Findings- Analyzes show that a high degree of complexity of the environment forces public organizations to adopt a planned approach from top to bottom, while the effectiveness of such an approach is limited to the simultaneous change of a complex environment. In addition, the routine change leadership activities is not sufficient to implement a change in a complicated environment. In order to overcome environmental dependence and maintain current trend in change process, public managers must be involved in leadership activities focusing on external environment. Innovation - The hypotheses can be further tested in future research and provides a basis for future research in the field of change management in public organizations. Focusing on the process and not paying attention just to the feedback of the process and the pre-process schema is the distinction of the present research

A new type of hybrid structure model is presented by meeting the requirements for combining traffic data to estimate the traffic situation in urban areas. This model is a combination of both spatial and temporary combinations. We first use the averaging operator for spatial composition, and then we propose a temporary correlation algorithm based on data compression based on the linear regression algorithm. The extension of the simulation results indicates the effectiveness and accuracy of the temporary correlation algorithm based on data compression as well as the temporary correlation superiority based on data compression relative to linear cross-sectional regression in terms of overall performance.

The study is considered an applied research in terms of purpose and descriptive survey in terms of methodology. The statistical population included 160 employees of Soroosh platform. According to Cochran formula 113 people were selected among them by the simple random sampling method. The standardized questionnaires of Spens and Robbins, Walton quality of work life as well as the occupational health questionnaire by Goldberg and Hiller were used as data gathering tools. The research hypotheses test was performed by Smart PLS software and research findings confirmed the role of health care mediating role in this regard. In addition, the results indicated that workaholism has a positive and significant effect on quality of work life, yet has a negative effect on occupational health.

Continuous improvement is a basic principle of Total Quality Management (TQM), which addresses all aspects of the organization, products, processes, and even company management. The company's quality process can be fluctuate over time; In this regard, self-assessment of the company's performance at sequential time periods can identify the weakness of the company and provide more realistic results for the managers. The purpose of this study is self-assessment of the company's excellence trend in time series with quality cost analysis. Self-assessment based on the ARAS model which relies on definitive and interval-fuzzy information is a new approach, used to evaluate the quality performance of one of the ceramic companies in 32 time periods in this study. In this regard, based on the cost of quality in one of the active companies in the field of tile and ceramic, self-assessment done was carried out ARAS method, and since all the costs of quality are not definite, linguistic variables and fuzzy numbers for these variables have been used. Based on the analysis, the performance of the company in the second  six-month period of 1383 and 1381 was better with the points of 0.938 and 0.935 compared to other periods and in the first sixth-month period of 1390 solar year and second of 1395 it had the worst performance. The performance of the company in recent periods is almost declining and the research results are consistent with the assumptions of the PAF model. The company, with more investment in prevention and evaluation costs, has been able to reduce failure costs and have more sales and profits. As a result, the company, having analyzed its financial issues, has to return to its previous investment trend in quality cost.

The aim of this study was to investigate a novel approach in order to design a human resource performance assessment questionnaire in sports organizations using an axiomatic design technique. The statistical population of the survey covers all human resources of the ministry(including managers, employees and experts) for the year 2017(N=840)where260samples were considered(n=260)based on Kerejsay and Morgan table. Data gathering tool is a researcher-made questionnaire which is based on human resource performance assessment. The research method is a combination of exploratory and sequential explorations based on the design of a questionnaire using the principle of the axiom design technique. In order to analyze the descriptive statistics data and before and after sport organizations questionnaire,the technique design based on the axiom and appropriate components and relevant indicators have been gathered. Also, apparent validity is determined according to the viewpoint of the professors and,on the other hand, the principle of information determines the content validity and the principle of independence is proportional to the structural validity. Reliability of the questionnaires is calculated based on Cronbach's alpha technique. The results illustrate that the reliability of the questionnaire validity which is designed by the axiom-based design technique is at a level of error of 0.5.Also, the design questionnaire has a higher Cronbach alpha coefficient using axial-based design technique at95%confidence level. A comprehensive performance assessment is achieved when the Ministry of Sports and Youth have the quality in three general criteria, namely the selection of staff, performance indicators of human resources and the maintenance of staff.

The goal of the current research was to factor structure and normalize performance evaluation questionnaire for human resources in the ministry of youth and sport. Statistical population of the survey covers all human resources of the ministry (including managers, employees and experts) for the year 2017 (N=840), where based on Kerejsay and Morgan table, 260 samples were considered (n=260). Data collection tool consisted of the researcher-designed questionnaire to evaluate the human resources performance. In order to analyze the data, descriptive and inductive statistics including Kronbauch α-coefficient was utilized for the calculation of internal consistency of the subscales, and the confirming factor analysis to assess the data analysis credibility scales using Amos version 20.0. Kronbauch α-coefficient exhibited the internal consistency of subscales. In addition, the results from confirming factor analysis revealed that ten-factor (Employee Hire, Occupational Familiarization, Training and Enabling, Effective Use of the Employees, Behavioral Indices, Psychological Properties, Capacities and Skills, Service Compensation, Preservation, maintenance and Succession) structure of the human resources analysis shows desirable fit. Hence, this study exhibits that performance evaluation questionnaire is a well-suited tool for evaluation survey by which researchers are able to use this questionnaire as a stable and reliable tool.

Nowadays tourism industry is the largest and the most diverse industry,and it is the main source of income, employment,infrastructure and private sector development in developed countries. In the meantime, identification and top tourism selection as the geographical area which one or more,or a series of historical attractions, natural and cultural,provides an incentive for tourists to visit and stay, could be a factor to improve positive competition among the places and be used in strategic planning. once a community becomes a tourist destination,the lives of residents in that community become affected by tourism activities. Over the past several decades interest in tourism as a tool for regional economic development has grown dramatically. Community leaders and economic development specialists have increasingly treated tourism as an important industry that can enhance local employment opportunities, tax-revenues, and economic diversity.Iran is a country with potential to attract a lot of tourists. with this potential we need a good strategic plan to improve tourism industry in different dimensions.The natural environment is crucial to the attractiveness of almost all travel destinations and recreation areas.Natural resources, the ecosystem, and regional ecology provide an important backdrop to commercial service areas.In this research we intend to select top tourism among the identified areas.in order to evaluate tourism places, the important criteria identified by the other researchers are considered and with the aid of multi-approval method based on voting theory, the top tourism region is chosen.Different researchers have been surveyed many studies to examine and locate the tourism places, each researcher do this with different methods, for example using AHP method, fuzzy, GIS, the combination of them and etc.In this paper we use multi-criteria method based on voting system which is based on expert's opinion. In addition to its simplicity, the other advantages of this method is the capability of applying in group decision making in the form of qualitative and quantitative criteria.This paper is based on a case study that is focused on evaluating 11 different regions in Semnan province. Finally Shahmirzad in Semnan and Abr jungle in Shahrud has been chosen as the top tourism regions of this province.

The aim of this paper is to present an optimization model in order to make a strategic plan to develop hydrogen refueling stations in a city when Origin–Destination (OD) data are not available. This model assumes two maximizing the traffic covered by the selected hydrogen refueling stations and minimizing the average distance of the city’s inhabitants to the nearest hydrogen refueling station. As OD data are considered to be unavailable, positioning the stations in the highest traffic zones is avoided by a new constraint that takes into account information on the distribution of existing conventional refueling stations. This model is applied to Mashhad of about 3 thousand square with a population of around 3 million. This application had used the results of a survey on more than 200 drivers on their current refueling preferences, their willingness to use alternative fuel vehicles and their minimum requirements (regarding maximum distance to be traveled to refuel and number of stations in the city) when establishing a network of alternative refueling stations.

However, there is no objective way allowing to evaluate the factors that may affect the performance of players, the application of subjective methods based on objective indicators cacould be considered as an absolutely effective instrument. In this study we suggested a two - stage model, first, using the algorithm of expert’s evaluation, we determined the performance indicators and the weight (importance degree) of each indicator, and then, using Additive Ratio Assessment method (ARAS), we performed player ranking process. 21 performance indicators that measure Body Size and Composition, Speed and Quickness, power, and aerobic Endurance was chosen. The proposed model was conducted for the evaluation of 16 volunteers of Shahrood university's basketball team.
