The study aims to evaluate the effective factors on creating a social bond in religious tourists using the services of recreational-sports complexes in Mashhad. The research method was quantitative with a structural equation model approach. The statistical population of the study was religious tourists who used the services of recreational-sports complexes in Mashhad. A total of 388 tourists were selected as the sample by convenience sampling. The measurement tool was a modified Adamczyk 25-item questionnaire based on expert opinions, which has four subscales (intimacy, security, passion, and commitment). The face and content validity of the questionnaire was confirmed by experts while the construct validity was confirmed using exploratory and confirmatory factor analysis. Reliability was also obtained by more than 0.7 using Cronbach's alpha. To analyze the data, descriptive and inferential statistical methods were used. Finally, the results revealed that the components of secure and intimate bonding are the most essential elements of creating a social bond in religious tourists using the services of recreational-sports complexes in Mashhad, respectively. Consequently, this study emphasizes strengthening indicators such as infrastructure development, equipment, and facilities to reduce risks, using new marketing methods, protecting the tourist information, attention to the opinions, interests, and values of religious tourists, creating an intimate and social atmosphere, creating a secure and reassurance environment, etc. to create a social bond in religious tourists using the services of recreational-sports complexes.

Religious tourism is one of the world's most critical current types of tourism, especially in Islamic countries such as Iran, which has a high potential for development and progress in this field. However, the development of this type of tourism in our country is not restricted to only religious cities but includes other cities in Iran. With its religious-pilgrimage functions, Sari city in Mazandaran province provides an appropriate ground for developing religious tourism as one of the main forms of tourism. The present research first conducted a set of observations in the region after studying library documents using the field method. After analyzing data from the observations, research questions were evaluated by organizations, experts, and the local community. The results were quantitatively examined by SWOT analysis. Finally, according to extracted concepts from qualitative and quantitative analysis, a model for the development of religious tourism was obtained based on library and field studies using interviews and then evaluated by experts. Results show that religious places of Sari city aren’t on the list of development priorities. It presents a model for development in this region with more challenges. Therefore, the qualitative and quantitative analysis results of this research imply a very appropriate situation and a high potential for religious tourism, emphasizing Imamzadeh in Sari city.

This paper presents an approach that uses both genetic algorithm (GA) and fuzzy inference system (FIS), for feature selection for descriptor in a quantitative structure activity relationships (QSAR) classification and prediction problem. Unlike the traditional techniques that employed GA, the FIS is used to evaluate an individual population in the GA process. So, the fitness function is introduced and defined by the error rate of the GA and FIS combination. The proposed approach has been implemented and tested using a data set with experimental value anti-human immunodeficiency virus (HIV) molecules. The statistical parameters q2 (leave many out) is equal 0.59 and r (coefficient of correlation) is equal 0.98. These results reveal the capacity for achieving subset of descriptors, with high predictive capacity as well as the effectiveness and robustness of the proposed approach.
