Leisure is an integral part of everyday life in today's world. Today, leisure is a new social arena in which various factors influence. Understanding these factors and examining their role and their impact on active (external) and inactive (external) leisure has been a major part of proper city management since this day. Therefore, in this study, using exploratory method, we sought to identify the factors affecting leisure time in district 22 of Tehran. This is a cross-sectional, applied research. The method of data collection is survey and its tool is a questionnaire. This study, using inferential statistical methods and SPSS software and statistical analysis such as correlation, regression and t-test, attempted to analyze the relationship between independent research variables (functional, security, aesthetic, transportation, economic, biological). Environment and infrastructure facilities) and the dependent variable (active and inactive leisure time), to identify the maximum impact and the least impact of the variables. The results showed that the effect and correlation of factors on leisure time (active and inactive) were different. In other words, indoor or passive leisure time is less affected by the external environment and context. But on the other hand, leisure time active or foreign in the 22nd district of Tehran is strongly influenced by background conditions and the external environment. Aesthetic variables and infrastructure facilities have the highest relationship with active leisure time and economic, performance and economic components have the least impact. In the passive leisure time, most of the impact factor is related to infrastructure and least to economic component.

The present paper deals with the analysis and analysis of spatial justice and its relation with social capital using descriptive-analytical research method. To assess spatial justice, the distribution of urban facilities and their per capita amount (per capita of religious, educational, medical, green, cultural, etc.) are used at local level. Then, they have been ranked by the multi-criteria decision-making method of Vicar County. According to the rates obtained from the vikor method and considering the final points, Shams Tabrizi and PehrAbad neighborhoods are in a state of affairs and the property districts, Sheikh Taj and TapaliBagi and Ohadi have a favorable situation.  The low-grade journals are in the new textbook and informal settlements. In areas such as Jahangir, Daneshghah, Sahand, Valiasr, Azadegan, new structures have been built as residential settlements over the past two decades. In the second stage, in order to evaluate the social justice of social capital indicators, a questionnaire was used that 383 questionnaires were prepared in relation to the population of each neighborhood. Five key indicators (trust, partnership, engagement, membership and security) have been used to assess social capital. The results show that neighborhoods such as Shams Tabriz, Khaje Nasir, Khan, Seidlar and Daraie have the highest social capital. In the third step, Pearson correlation methods and weight geographic regression have been used to analyze the relationship between spatial justice and social capital. In this method, the correlation between variables is shown in the neighborhood level. Output layer The standardized residual geographic weighted regression analysis between spatial justice and citizens' satisfaction shows that in Shams Tabrizi, Azadegan, Khajeh Nasir 1 and 2, Sheikh Taj, Daraie, and Pasdaran, there was a positive spatial relationship. This means that the spatial development of these areas has a positive impact on improving the quality of life and social capital, the greater the spatial justice in these areas will increase social capital.

Abstract
With the rapid growth of population and urbanization since the last century, the complexity and understanding of the spatial organization of the city, as well as the ability to predict urban events in its spaces, have become difficult and in some cases impossible. Karaj metropolis is one of the major metropolitan areas of Iran that has been experiencing rapid population growth and this has led to complexity of space and consequently to complexity of organization recognition and analysis and its spatial structure and impact of livelihood components. It has become a spatial system. The main purpose of the present study is to identify the role and impact of Karaj's spatial organization on its nuclear viability. The research method is quantitative and descriptive-exploratory. The study area was Karaj metropolis and its main nuclei. The statistical population of this study is citizens living in the sub-nucleus of Karaj. The sample size was 378persons. The data used in this study were collected through library and field research. Data were analyzed using spatial statistics, spatial arrangement, and T-test and Friedman test. The results show that the Karaj metropolitan organization and spatial structure are interconnected and connected to some of the major routes, forming sub-nuclei away from the core and thus transferring the functional and service applications from the center to be the peripheral nucleus. This has affected the viability of the core. Decrease in biodiversity has occurred in different physical, social, economic and environmental dimensions that have affected the environmental and economic aspects less than the other two dimensions, so it can be concluded that the Karaj Spatial Organization has an impact on its viability.
