However, usually in urban environments, sustainable housing plays the greatest role in increasing and realizing physical security. In this regard, the aim of this research is to investigate and analyze the indicators of sustainable housing and their role in the realization and promotion of physical security in the neighborhoods of the 17th district of Tehran metropolis. The research method in this study is descriptive-analytical and practical in terms of purpose. The method of data collection was done in the library and field, and the sampling was purposeful, and 20 urban specialists and experts were selected for questioning. Weighting and determining the value of subjective indicators (33 sub-indices in 6 categories of equitable distribution of residential services, efficient transportation, vitality, healthy environment, fair housing, and dynamic cultural heritage) and objective (14 sub-indices in 3 categories of design-architecture, technical indicators - Engineering and accessibility), using the methods of pairwise comparisons and fuzzy AHP, and the desirability of each of the indicators and their role in physical security, separated by localities, are displayed in the GIS environment. The results of the research showed that Yaftabad and East Abuzar neighborhoods have a favorable situation in terms of physical security with weight (0.132 and 0.084), respectively. Golchin (0.078) and Boloursazi (0.076) locations are in acceptable condition; Bagh Khazaneh (0.074) and Emamzadeh Hasan (0.073) neighborhoods are in average condition; The localities of Jalili (0.066), West Abuzar (0.064), Zehtabi (0.063) and Emam Sajjad (AS) (0.062) are in poor condition and the localities of Vesfanard (0.060), Azari (0.058) ), Moghadam (0.057) and Zamzam (0.050) are in unfavorable conditions.
IntroductionAt the same time, housing is the main factor of people's socialization towards the world and the major and decisive capital in the social organization of space, which plays a very decisive role in the formation of individual identity, social relations, and collective goals of people. Housing is more than a physical structure, it is an institution with a multi-dimensional function, which has different spatial, architectural, physical, economic, social, financial, psychological, and medical dimensions. Housing is the most important element of the city, and in the sustainable development of the city, paying attention to its sustainability is known as its most essential aspect. Therefore, the relationship between sustainability and housing is two-way. In this regard, man has different needs during his life, which he plans to fulfill. In today's world, in terms of the expansion of urbanization and the special interactions of citizens with each other, as well as from the perspective of urban design and architecture, security in cities has gained special importance. The need for security in cities has brought spatial and physical reflections as an important and vital principle. Therefore, establishing security in the urban structure and giving citizens a sense of security is increasingly important. In fact, the basis of urban life is based on this axis.
Materials and MethodsThe research method used in this study is descriptive-analytical and practical in terms of purpose. The method of data collection has been carried out in the form of the library (examination of documents, statistics information, and research related to the subject) and field (interview and questionnaire distribution). Sampling was purposeful and 20 urban experts were selected for questioning. In this research, to analyze the indicators (two categories of mental and objective indicators); In the analysis of subjective indicators, scoring was done using the opinions of specialists and urban experts, and finally, using the "pairwise comparison" method, the indicators were weighted, and the effects of each of them (indicators) were determined with different intensity and weakness in the localities. For the objective indicators, weighting and ranking were done using Fuzzy AHP, and the layers related to each of their dimensions and sub-indices were prepared in the GIS environment, finally, the neighborhoods in terms of the impact of sustainable housing on physical security were divided into neighborhoods and stratified into three Weak, medium and favorable categories were identified.
Results and DiscussionThe results show from the objective indicators aspect, in terms of design-architecture dimension indicators such as the number of building floors, area (smallness), population density, indefensible spaces (lack of lighting), and residential density; The neighborhoods of the 17th district of Tehran are not very different from each other. Only "Yaftabad neighborhood" is in a favorable situation in this regard. "Emamzadeh Hasan neighborhood" is also in an average condition and the rest of the neighborhoods are also in an unfavorable condition. In this regard, the physical texture of area 17 has the following characteristics: extremely worn and dense, incoherent and disjointed, irregular in terms of the type of use and having strong interference of use, having granularity with an increase in fine-grained elements, compactness of the texture and their location on Mainly narrow and long passages, high wear and tear of residential and non-residential units, construction of buildings using non-resistant and non-standard materials, old buildings, etc. Finally, by scoring and summarizing the weight of all the indicators related to the physical security of the neighborhoods of the 17th region, they were categorized into 3 categories with favorable, medium, and weak spectra. The localities of Yaftabad and East Abuzar, Boloursazi, and Golchin have a favorable situation in terms of physical security. Bagh Khazaneh and Eemamzadeh Hassan and Jalili neighborhoods are in average condition and West Abuzar, emam Sajjad, Zehtabi, Azari, Moghadam, Wesfanard and Zamzam neighborhoods are in unfavorable conditions. From the metal indicators aspect, "Azari, Moghadam, Golchin, Wesfanard and Zehtabi" localities are in poor condition; "Boloursazi, Eemamzadeh Hasan and Yaftabad" localities are in average condition and "Bagh Khazaneh, East Abuzar , West Abuzar, Emam Sajjad" localities ), Jalili and Zamzam" are in the ideal state of stable housing in order to achieve physical security. It should be noted that this classification is based on the scoring of selected experts on subjective indicators.
ConclusionIn this research, after stating the features of sustainable housing in the target area and checking the normality or abnormality of the indicators, the most important features affecting the promotion of physical security in the said area were determined. In this regard, the selected indicators were divided into two subjective and objective categories. Subjective indicators were scored and validated by urban experts. For this purpose, 33 sub-indices were identified and extracted in 6 categories of fair distribution of residential services, efficient transportation, vitality, healthy environment, fair housing, and dynamic cultural heritage, and the "paired comparisons" method was used to weight and normalize them. Also, in the objective indicators section, 14 sub-indices were selected in 3 categories of design-architecture, technical-engineering, and accessibility indicators, and for their weighting and normalization, the fuzzy AHP model was used in the GIS environment. The results showed that the neighborhoods identified based on the degree of desirability of having stable housing in order to achieve physical security based on subjective and objective indicators are very different from each other.

Today, globally, there are dramatic changes in attitudes toward unforeseen events; so, the prevailing view has shifted from focusing solely on reducing vulnerability to increasing resilience to disasters. According to this view, risk reduction programs should seek to create and strengthen the characteristics of resilient communities and also pay attention to the concept of resilience in the accident management chain. Going from the physical to resilience perspective, the need for a comprehensive, holistic framework and system that combines different aspects of the city with less visible but effective aspects (human behavior) creates economic, social, physical, and institutional dimensions for the issue of resilience. Moreover, special and sensitive urban centers are among the areas that are considered as vital arteries due to the complex structure of urban life and the dependence of urban society on them, and as a result, the issue of their vulnerability and resilience is very important. Because any failure in it leads to many problems for urban society, reduces the quality of life, and ultimately fails in development goals. One of the challenges of urban management in the District 11 of Tehran is the resilience of special, vital and sensitive centers. Therefore, it is necessary to take steps to achieve resilience in the region and these important centers based on components and indicators of resilience and respond properly to the needs of citizens to protect the region from possible crises and its vulnerability. In order to achieve development and reduction of sustainability. Accordingly, and considering the necessity of the subject, the present study seeks to identify the components and indicators of resilience, rank them and finally, prioritize the areas of Tehran's District 11 in terms of having components and indicators. Therefore, the main research question is as follows:- What is the current situation of vital and sensitive special centers in the District 11 of Tehran in terms of resilience indicators?
MethodologyThe present research is in the field of descriptive-analytical study in terms of content and method and applied in terms of purpose. Field and library methods have been used to collect and prepare the required information. The statistical population of this study includes a group of experts and experts in the field of geography and urban planning that available methods selected 20 people. Indices were distributed among the statistical sample in a questionnaire, which had a five-point Likert scale. Formal validity was used to assess the validity of the questionnaire, and the reliability estimate was calculated with Cronbach's alpha. The obtained alpha coefficient is equal to 0.832, which indicates good internal cohesion and high reliability. The SWARA multi-criteria weighting method was employed to analyze the obtained information and evaluate the degree of importance of each indicator. Also, WASPAS method has been exerted to determine the extent of benefit of each area of the study area.
Results and discussionAccording to the data analysis, the most important physical-environmental components with a final coefficient of 0.5551, social with a coefficient of 0.2523, economic with a coefficient of 0.1262, and institutional-managerial with a coefficient of 0.064, respectively. The above studies show that focusing on the components by considering their priority will lead to the realization of resilience in the study area. Because by looking at the results, we will find that the effect of these components (either directly or indirectly) has a significant role in determining the status of the study area in terms of resilience. The status of the four areas of District 11 of Tehran among the components studied in the present study shows that area 2, with a total score of 23.2, is in the first place, and it can be acknowledged that this area is in a better position than other areas in terms of resilience indicators. Following, area 3, with a score of 67.22, is in the second rank, and area 1 with a score of 22.35 and area 4 with a score of 22.22 are in the third and fourth ranks. As the results of the WASPAS method show, the scores of the regions are close to each other. In general, all the areas have almost the same situation, and their differences are insignificant.
ConclusionNatural and human hazards are one of the serious and worrying challenges that today's cities face in pursuing population expansion and urban boundaries more than ever before. In such a world, urban areas are the winners who, by carefully identifying and analyzing their current situation, take steps to achieve the most resilience, which is one of the new approaches in urban management. Accordingly, the present study sought to identify the components and indicators of urban resilience, rank them and finally, prioritize areas in the District 11 of Tehran in terms of urban resilience components. In this regard, with library studies, four components and 13 indicators were identified. In the following steps, using experts' opinions and experts, the components and indicators were ranked, and finally, the areas were prioritized using SWARA and WASPAS methods. As the analysis of the findings showed, it is necessary that in the first place, the relevant authorities review and reform the existing management structures in order to achieve resilience components with emphasis on the physical-environmental dimension, which has the highest score in terms of importance among professionals, in area 4 of District 11 (according to the lowest score). This indicates the need to establish integrated management of institutions in the region and at the national level. Therefore, according to the issues and research findings, it can be said that in order to improve the resilience of District 11 of Tehran, which is one of the most important districts of the city and the country, it is essential to establish the basis for the realization of physical-environmental, social, economic and institutional-managerial components.

Of course, the issue of worn-out and inefficient urban neighborhoods and recreation of these neighborhoods is a complex and multidimensional issue, so any issues related to recreational urban texture regeneration should be evaluated in a multidimensional way and a combination of different factors. In this study, systematically and systematically, the key proponents of effective regeneration of worn-out neighborhoods of District 12 of Tehran metropolis have been systematically identified and analyzed. In this study, first, 40 environmental factors were extracted in six different political, economic, socio-cultural, legal, managerial, and physical fields using environmental and Delphi techniques, and then using the Delphi method of managers, the cross-effects matrix of the components Is formed. In the next step, matrix analysis was performed through Miccom software. The results of scattering of variables in the influence axis and factor influencing in the Mickemak software indicate the instability of the system in recreating the study area and accordingly five variables were identified. Finally, given the high score of direct and indirect influence of the factors, ten key factors were identified as key drivers in the future recreation of the area. Among the factors considered, socio-cultural variables had the greatest impact on recreation of the study area and political factors had the least influence.

مدیریت زمین شهری جهت کنترل رانت یکی از عرصه های کلیدی جهت پیش برد توسعه پایدار در کشورهاست. از این رو، محدویت در منابع و عرضه زمین در مقابل تقاضای روز افزون جمعیت شهری باعث ایجاد ارزش اضافی زمین و بروز تقاضای سوداگرانه شده که این امر باعث افزایش قیمت زمین و به تبع آن مسکن شده است. بنابراین بکارگیری سیاست های مناسب جهت برون رفت از وضعیت نامناسب رانت در فضاهای شهری امری ضروری بوده و از جایگاه بالایی برخوردار می باشد. پژوهش حاضر، با استفاده از تعداد مولفه های اثرگذار بر افزایش رانت، در منطقه یک کلانشهر تهران تحلیل می کند. روش پژوهش توصیفی- تحلیلی است و در آن، از تکنیک چندمعیاره (دیمتل) برای شناسایی مولفه های اثرگذار و اثرپذیر بر رانت استفاده شده است. یافته ها نشان می دهد که در بخش مدیریتی، مولفه تراکم ساختمانی، در بخش اقتصادی، مولفه قیمت زمین و مسکن و در بخش اجتماعی، مولفه رشد سریع جمعیت جز اثرپذیرین مولفه ها در افزایش رانت داشته اند و باعث ناپایداری در مدیریت و برنامه ریزی شهری منطقه یک کلانشهر تهران شده است.کلید واژگان: رانت، زمین، رانت زمین شهری، منطقه یک کلانشهر تهرانAnalyze the factors affecting the increase of urban land rent in district one in Tehran metropolitanAbstract Urban land management for rent control is one of the key arena for sustainable development in countries. Hence, the constraints on land supply and supply against the increasing demand of urban populations have created an additional surplus of land and a speculative demand, which has led to higher land prices and, consequently, housing. Therefore, it is necessary to use appropriate policies to get out of inappropriate rents in urban spaces and have a high status. The present study, using the number of factors affecting the increase in rents, is analyzed in district one in Tehran metropolitan. The research method is descriptive-analytic and uses multi-criteria technique to identify the effective and effective components on rent. The findings show that in the managerial sector, the component of construction density, in the economic sector, the price of land and housing, and in the social sector, the fast population growth component has been associated with increasing components of rents, causing instability in urban management and planning in district one in Tehran metropolitan.Keywords: Rent, land, Urban land rent, District one of Tehran metropolitan

This method should provide sufficient knowledge to identify the nature of problems and the identification of individual characteristics, socio-economic, physical, environmental and management, would in effect do the "Back to Balance" against natural hazards. This feature Back to Balance the same resiliency. The term resilience has a very long history and its use goes back at least a century BC. According to the different interpretations of the concept of resilience, this term is rooted in the traditions of various disciplines such as law, engineering, ecological and social sciences. Today, the concept of resilience has entered the field of planning with different orientations (social, economic, physical, and administrative, etc.).Although it still focuses more attention on environmental issues and a large part of its exploration dedicated to managing the environmental hazards such as earthquakes, floods, hurricanes and global warming. Tehran, as a result of political and economic influence, special conditions to deal with the crisis in terms of the influence of natural disasters and crisis management in terms of organizational structure and legal. In this respect, residential and urban areas of 12 with characteristic their history can be acute against the imbalances caused by natural hazards and create a crisis in urban life. Therefore, the present study has been prepared for the purpose of stability analysis flexibility in District 12 of Tehran metropolitan city.
This is of cognitive research that has been done for analytical and descriptive. All data is obtained in the manner of library and field. The library of available resources and work conducted the form of a questionnaire survey. Questionnaires have been used of type Likert spectrum (numerous, high, high, somewhat, relatively low, low and very low), and its completion is done by fieldwork. Statistical population has problems of urban planning experts, among them 80 people were interviewed for targeted samples. Resiliency that includes four dimensions (economic, social, ecological, environmental and institutional). Was approved the validity of the index by 7 experts manage urban planning problems. For measuring reliability coefficient is calculated Cronbach's alpha equal to 0/79. For data analysis, the use of statistical analysis such as frequency, maximum and minimum, average and standard deviations, T-Test one sample test and Friedman nonparametric test
The results of the indicators of urban resiliency against natural hazards suggests that economic indicators 73/24 Average been determined and relatively low level, ie below the average level. Results of the test showed one sample T-Test is an indicator of economic status of urban resilience against natural hazards of poor utility. As well as the social, ecological, environmental and institutional (organizational) urban resilience against natural hazards associated with poor utility. Finally the 12 metropolitan Tehran metropolitan areautility resilience against natural hazards with respect to all dimensions were too weak. Friedman test results on the scoreboard indicators showed that the index of environmental sustainability (20/33) related to the ecology and environment in the first rank the importance of urban resilience and adaptability Index System (10/11) related to next institutional (organizational) is set as the least significant indicator. Also, significant chi-square statistic is calculated at a rate of 09/67 in three degrees of freedom at the level of 0.000. So, with a probability of 99% can be said that there is a significant difference between the performance rating of 80 specialist urban resilience dimensions (economic, social, ecological, environmental and organizational) against natural hazards, and not the distribution of the same rank.
This research been prepared with the aim of assessing the scale of urban resilience against natural hazards in District 12 of Tehran Metropolis. Results showed that social, environmental and institutional ecology and urban resilience against natural hazards associated with poor desirability. According to this result, it is concluded that the region as a whole is resilient against natural hazards. In this direction, the resilience approach guidance to managers and practitioners use of flexible decisions and concerted policy for urban management. Build resilience in this area to support programmes should invest in organizing access to both external and existing resources in a fair manner, with a coordinated governance structure, and to facilitate social solidarity and support as part of disaster response. The findings also stress the importance of taking an ecological approach to studying resilience to disasters. Many factors from individual, community, and societal levels seem to be important in shaping resilience perceptions of natural hazards survivors. Understanding this evidence will help to validate and further develop indicators of resilience. Our findings point out that, despite existing pre-disaster vulnerabilities, resilience can be fostered following disasters if community members perceive availability of aid and support and mobilize resources Hence, psychosocial support programmes should invest in organizing access to both external and existing resources in a fair manner, with a coordinated governance structure, and to facilitate social solidarity and support as part of disaster response. The findings also stress the importance of taking an ecological approach to studying resilience to disasters. Many factors from individual, community, and societal levels seem to be important in shaping resilience perceptions of natural hazards survivors. Future research should conduct multiple levels of analysis with an all-hazards perspective to reveal how they can be integrated to increase adaptive capacities. Future research should focus on the process of capacity building through informing action to better prepare for disasters. Finally, this research tells us that due to the resiliency of the city will be able to have knowledge of all relevant indicators in the resiliency and reduce the adverse effects of these risks in urban communities.Keywords: sustainability, resiliency urban, natural hazards, District 12 of Tehran Metropolis
