The purpose of the present study was to optimize and improve the status of ticket sales at Tehran Azadi Stadium and reduce customer waiting times in queues using methods Simulation and Multi-criteria decision making (MCDM). First, using objective observation and time-out, the waiting time for spectators in the ranks of the ticket and presentation and physical examination calculations and then using the simulation software, The entire service process has been simulated from the moment the ticket is purchased until the moment they enter the stadium, and the average waiting time for spectators in the queue for the provision of services is calculated. And then we look at the problems with ticket sales. Also, using interviews with elite and expert people, there are some ways to reduce waiting times for customers in the queue. And each of these views was examined using the simulation software; then scenarios were developed to improve the status quo and then, using multi-criteria decision-making methods, we ranked the scenarios and selected the best scenario.

Purpose: This research aims to investigate the quadruplet role of modern media (education, informing, making social participation, and culturing) on the development of Zurkhaneh sport. Method: This research is applicable in terms of objectives and is descriptive research in terms of data gathering methods. The statistical society of this research includes the athletes, experts, and activists of sports media in the context of the Zurkhaneh sport. Because the exact number of this society was not clear, the number of 384 persons were selected by random sampling. Its measuring tool was the researcher-made questionnaire that 12 professors and experts approved its content validity and its reliability was calculated using the compound reliability (Dillon – Goldstein) and was about 0.82. In addition, the SPSS software was used to analyze the data and PLS software was used to preset the model. Results: The results show that the “informing” factor had the maximum role in developing the Zurkhaneh sport with the factor loading of about 0.93. The other factor that had many roles in developing the Zurkhaneh sport was the “social participation” with the factor loading of about 0.91. The “education” factor with the factor loading of about 0.90 was in third place and the last factor was the “culturing” with the factor loading of about 0.90. Conclusions: According to the results of this research, it could be stated that modern media have obtained such power in the communication era that could affect public opinion. Therefore, the potentials of the modern media and their infinite capacity can be used by proper and correct operational planning to make great movements in developing various aspects of Zurkhaneh sport inside and outside of the country.

The purpose of this study was to investigate the effect of strategic thinking skills on the effectiveness of strategy creation process of team sport federations in Iran. 57 questionnaires distributed among the managers of team sport federations to collect the required data. Strategic thinking skills questionnaire and effectiveness of strategy creation process questionnaire adapted from Moghimi and Ramezan questionnaire (2015). Structural equation modeling with partial least squares (PLS) approach was employed for data analysis. The results indicated that strategic thinking skills of managers had a significant effect on the effectiveness of strategy creation process in team sport federations. According to the findings, improving the strategic thinking skills of managers in sport federations, is critical in the process of creating effective strategies.

Background: Sports facilities are one of the most commonly used services in the city with a significant role in improving the physical and mental health condition of citizens thus a proper procedure is required to locate and distribute them. Aim : The purpose of this study is to design a comprehensive model for the optimal location of sports facilities. Materials and Methods: The research method is descriptive-analytic based on information gathering and is applied research based on objectives. The opinions of 20 experts have been used to design the model using the Delphi method, and weighting the effective criteria in the sports facilities location. The weight of each criterion has been obtained as population density (0.47), access (0.31), development potential (0.14), and adjacency (0.08); furthermore, the Kendall coefficient of concordance (0.74) in the third step of the Delphi method shows the strong agreement between the experts, regarding the proposed model. The proposed model consisted of six steps: 1. Aim; 2. Verification of the functional area of the existing sport facilities and specific restrictions of the area; 3. Introducing and weighting the important criteria in the sports facilities location; 4. Identifying the most suitable locations for constructing the sports facilities; 5. Evaluating the needs of users; 6. Selecting the best spaces and prioritizing them. Results: The results of the model showed that the most important criteria for locating sport facilities are population density, access, development potential, and adjacency. Additionally, it was indicated that the agreement between the experts increased over time. Conclusion: According to the proposed model, it is possible to identify the points that are suitable for constructing the new sports facilities.

The purpose of this study was to investigate the level of physical activity of faculty members at Allameh Tabatabai University during the coronavirus pandemic. This applied research has been done by a descriptive method. The statistical population of the study was the Allameh Tabatabai University faculty members in Iran. 284 people were selected through the available sampling method. A valid and reliable researcher-developed questionnaire was used for data collection, and a T-test was conducted for data analysis. The results of this study showed that the faculty members of the university do not have intense and moderate activities during the COVID-19 pandemic. But the general knowledge about the benefits of exercising during the coronavirus period has increased. In a general conclusion, COVID -19 crisis has created inactivity among university faculty members. Therefore, it is necessary to design and implement plans to increase the physical activity level among faculty members.

The aim of this study was to develop a model for examining the mediating role of job characteristics in the relationship between structural empowerment and professional commitment of referees in female's Futsal Premier League. To collect the required data, we distributed the research questionnaires among 75 Futsal Premier League referees invited to the pre-season qualifying class in 2020, and finally we received 63 valid questionnaires. We conducted structural equation modeling, confirmatory factor analysis and path analysis for data analysis by using PLS Smart software. The findings demonstrated that structural empowerment can predict professional commitment, but the relationship between the two variables was not significant. The relationship of structural empowerment with job characteristics and professional commitment was not significant. The mediating role of job characteristics in the relationship between the two variables was not significant. The components of information sharing in structural empowerment, attachment to professional commitment and diversity of skills in job characteristics had the highest averages. Given that the lack of significance of the relationship among structural empowerment, professional commitment and job characteristics, is questionable and it should be assessed in great details.
