Presenting a comprehensive model and identifying effective factors in the analysis of combat sports competitions was the goal of this article. For this purpose, the researchers referred to experts in the field of martial arts in Iran and collected information from them through in-depth interviews, and then the data obtained from twenty interviews and documents were coded and analyzed. The research method was qualitative. The DIMTEL technique was used to find the model levels of the key factors of the analysis of combat sports competitions and any cause and effect relationships between the criteria. The results of the grouping of the codes showed fifteen components in four levels, which include the formation of separate training workshops for trainers, the use of skilled and educated people in this field, the intelligentization of the topic of analysis, and the formation of analysis teams for different age groups in the team. According to the results of the study, the presented model can be used as a sports analysis tool for the success of martial arts coaches in guiding and leading teams. In martial sports, the coach is one of the main and central figures. In this way, the analysis of martial sports competitions were extracted and confirmed, and the framework of the study was drawn and its suitability was confirmed. The purpose of this study is to provide a comprehensive model and identify effective factors in the analysis of martial arts competitions. The researchers referred to martial arts experts and collected information from them through interviews, and then the data from the interviews were coded.

Due to the diversity of polymers as well as their complex behavior, research in this field is still widely developed. Because biodegradable polymers become decomposed in the human body after decomposition, they are more commonly used because surgery is not required to remove these polymers from the body after the drug is released. Understanding the mechanism, modeling and studies of drug release from homopolymers, copolymers and mixtures of this family of polyesters is the focus of this research. In this research, the release of drug from homo and biodegradable copolymer in pure form with drug and finally the mixture of the two with drug has been investigated to determine the differences. In the proposed model, the equations that represent the degradation of the polymer are used to be able to predict the degradation of the polymer. The drug used is paclitaxel, which is a very important drug for chemotherapy. Since this drug is administered every 3 weeks for 3 hours, it is necessary to use controlled systems. Therefore, the purpose of this study is to achieve a predictable model for controlled release of paclitaxel, so that this model responds to the release of paclitaxel at any time.
