Abstract
The aim of this research is to identify and prioritize the criteria for selecting base coaches for basketball teams using the DEMATEL technique and network analysis process under fuzzy conditions. This study is considered applied in terms of its objective and methodology and falls under the descriptive category. The statistical population of this research consists of 10 university experts and opinion holders who have experience in coaching base basketball teams or have relevant qualifications in human resource management in sports. Initially, through library studies and interviews with experts, the criteria for selecting base basketball team coaches were identified. After identifying the criteria, using the DEMATEL method, the internal relationships between the criteria were determined. Then, the expert questionnaire was used to determine the importance of each criterion using the Analytic Network Process (ANP) method. The results showed that among the main factors, technical and legal competence with a weight of 0.128, psychological and communication skills with a weight of 0.075, and inclination for growth and excellence with a weight of 0.046 had higher importance. Among the sub-criteria, having a coaching license with a weight of 0.052, participation in special base coaching courses with a weight of 0.039, and mastery of psychological growth concepts with a weight of 0.034 had higher importance. Finally, it was shown that all the identified criteria are influential in selecting base basketball team coaches, and it is necessary for managers to consider these criteria in the selection process.

Abstract
The purpose of this research is to measure and model the release of carbon monoxide pollutant in the surrounding space of Azadi Stadium in Tehran during sports competitions. Basic data were obtained by laboratory measurements and inquiries from specialized centers. Modeling was done by Austal View software, Version 7 and under four scenarios. The prediction of pollutant concentration was simulated at a height of 5 meters. The modeling area was considered a circle with a radius of 1 km from the center of the site. The resulting data were compared with national and international standards. The initial concentration of the pollutant in the hot and cold seasons of the year was 1.432 ppm and 2.331 ppm, respectively. The amount of pollutant emission for the state of "completion of parking capacity" and "semi-complete state" was 81.45 and 37.5 kg, respectively. Zoning maps showed that in all four scenarios, the highest amount of emission was in the east direction. The highest amount of carbon monoxide production and emission is related to the first scenario (completion of the parking capacity and the cold season of the year) and the lowest amount of carbon monoxide pollutant emission is under the fourth scenario (failure to complete the parking capacity and in the warm season of the year). Although the condition of this pollutant in Tehran's Azadi sports complex and during sports competitions has not exceeded the standard. By using management and engineering solutions such as: not keeping lights on in place, using exhaust filters, properly designing the parking space and reducing the duration of stopping, it is possible to avoid the production and release of a large part of pollutants.
