This research was conducted with the aim of policy-making and sociological analysis of elite migration in martial arts. It was a mixed-method study with an exploratory sequential design. In its qualitative section, the grounded theory approach based on the Strauss and Corbin model was used to comprehend the nature of migration among martial arts elites. The researcher also delved into the mental aspects of this reality, employing the pragmatism paradigm.
The quantitative section utilized a survey method through the use of a questionnaire. Following interviews, codes, concepts, and themes were extracted, and the questionnaire was formulated based on these elements for use in the statistical population. The study population included professionals and athletes in martial arts, with 12 purposively selected individuals, and martial arts athletes in Tehran city, totaling 384 individuals who were conveniently selected.
The research tools included semi-structured interviews and a researcher-designed questionnaire. The results indicated that the discovered components in the qualitative section fell into four categories (economic factors, social factors, political-administrative factors, and psychological factors). Factor analysis revealed that all four dimensions of social, political-administrative, economic, and psychological factors significantly influence sports elite migration, and this influence is respectively desirable and highly desirable. None of these relationships were weak; in other words, all significant components play a influential role in the migration of martial arts elites. However, economic factors with a factor loading of 0.71 had the highest impact, while social factors with a factor loading of 0.51 had the least impact.

The urban system of Iran, in addition to the problems and problems related to the rapid growth of the population and the increase in urbanization, with challenges such as the unbalanced and unbalanced spatial structure, the incompatibility of the cities with the natural environment and most importantly with the reduction or depletion of natural resources, crises and numerous pollutions. environment is struggling, at the same time and from another point of view, according to the developments in the field of information and communication technology, the city is passing from a purely physical settlement with visible and traditional functions to a physical settlement with invisible functions. And the new is next to its traditional functions. With these interpretations, the goal of this research is the realization of a smart city based on the physical indicators of smart growth. The research method is applied in terms of purpose and descriptive and analytical. The required sample size was calculated based on Cochran's formula and Morgan's table, and according to the total number of the statistical population of the study, which is 160 people, the sample size of the study was 113 people. The data was collected using a researcher-made questionnaire. The findings show that among the regions of Ardabil city, regions 1 and 4 had the potential of a smart city with 0.33 and 0.26, respectively, and region 3 with a score of 0.20 had half the potential and region 2 as well. With a score of 0.19, they lacked the potential of a smart city. The results show that there is a significant difference between the urban areas of Ardabil in terms of compatibility with smart urban growth indicators, and the extent to which different areas have research indicators is not the same.

Today, the limitation of fossil energy and the degeneration of the environment affected by the increase in the concentration of carbon dioxide resulting from its use and other difficulties and shortages of electricity, along with increasing energy demand, especially in developing countries, are valid and necessary evidence that makes use of clean and accessible resources, such as solar energy, in abundance. Due to its location on the Earth's solar belt, Iran has a wide potential for the use of solar energy. There are ways to use solar energy and generate electricity, including CSP technology for solar thermal power plants or photovoltaic systems. In this research, using GRASSHOPPER software, we have investigated the effect of shade and other effective indicators in optimizing energy consumption by examining the condition of traditional and contemporary houses, considering the materials used in these houses in Shiraz, and the energy results for them have been evaluated and compared in different months.

The current research has found a semantic nature with the three concepts of urban management, smart city, and passive defense requirements, whose main goal was to present the requirements, elements, and components of passive defense in a smart city. A model whose role and form were found in the framework of urban governance approaches, such as the integrated management model, New approaches to urban management concepts such as participation, accountability, transparency, justice, local communities, distribution of power and authority, all-round urban sustainability, the presence of institutions in the decision-making system and urban decision-making, development of local institutions, institutional capacity building, convergence of institutions, social capital, synergy of institutions, suitable legal system, citizenship rights, etc. are its main keywords, and according to the mentioned concepts, it systematizes the urban management system. The current studies show that the principles of urban management are not compatible with the requirements of passive defense. The results show that Tehran is in an unfavorable condition in terms of intelligence, but in terms of comparing the components of smart city management, smart life is in the first place and smart governance is in the fifth place.

In order to make the optimal urban governance policy in metropolises, the research method of this study is based on the theory of basic empirical data, Strauss and Corbin, and semi-structured interviews were also used to collect data. Also, sampling was done using the theoretical sampling method and using the snowball and target method. The results of the analysis of the data obtained from the interviews are presented in the method of space, center and selection, as well as in terms of causes, conditions, intervention conditions, management methods and results. The results of this research show that the administration of Rasht city depends on strategies such as decentralization, reconstruction of structures and processes, participation of stakeholders and delegation of power to managers with high knowledge and ability. The reform and cooperation of several decision-making institutions, recognition of the primary missions of responsibility and accountability (in the first stage), streamlining the direction of good governance in Rasht metropolis and (in the second stage through the central role of city management) at the community level.

The Covid-19 pandemic has become a health problem due to its high rate of transmission and rapid spread worldwide. Therefore, in recent years, many researchers have investigated and spatially analyzed the covid-19 disease with different factors in order to policy and better manage these conditions. Therefore, in this research, by choosing the city of Gerash in Fars province as an example of the southern cities of the country, the efficiency of the GWR model was measured to determine the high-risk areas of death due to corona disease in different age groups.
In this research, the geographic weighted regression (GWR) model has been used to investigate the relationship between deaths caused by Corona in Gerash city and different age groups and spatial modeling for urban policy .
The results showed that among the 10 age groups, one of them, that is, the age group of 61-70 years old, has a significant relationship with the number of deaths, and the highest degree of correlation can be seen in the west of Gerash city, followed by the highest degree of correlation, respectively. It is 0.97 to the north, 0.92 to the center and 0.88 to the south
The specified places are economically weaker than other parts of the city, and the sections of society that are economically weaker are more vulnerable than other sections. Also, the practical results of the GWR model and its high power for modeling will help managers and planners to identify the critical points of pandemic conditions and use them for policy and better management.
