Quality of life is one of the most important issues in all researches regarding social, economic, cultural and political issues. These areas, have a suitable potential, have attracted the attention and desire of the planners, managers and all the managers of urban management. In this dissertation, the aim is to identify and measure the effect of effective components on quality of life of district 12 of Tehran to increase the quality of environment. On these bases, the criteria for satisfaction with the quality of life in these urban areas is from the residents' and their point of view. Regeneration of inefficient urban areas and the use of existing resources and potentials, ultimately is to improve the quality of life in these urban areas. Therefore, at first, the global background of quality of life has been studied and then, taking into account the conditions and characteristics of inefficient urban fabrics, a suitable model of conditions in Iran has been taken. Descriptive-analytical research method and various documentary methods have been used to collect required data. To analyze data such as descriptive methods and statistical tests (Kolmogorov–Smirnov, pearson and multi-variant regression) have been used. The final results indicate that the appropriate model for increasing the quality of life in District 12 of Tehran is based on the fear of government intervention and greater use of private sector and NGOs and using desirable potentials and appropriate infrastructures can play an essential role in the increase of quality of life.

The temporary settlement of the affected population is a process that requires the identification of suitable spaces for the settlement of the population, planning, management and providing appropriate solutions before and during a possible earthquake. Region 3 of Tehran municipality is a prone area for earthquakes and the presence of faults affecting the vulnerability of Tehran city, including Masha faults, North Tehran fault, and Ray fault, as well as the influence of faults in and around the region, including Mahmoodieh fault, Davodieh fault, Telo Bayan fault, and Xian and Kausar increase the risk of earthquakes in this region. This issue has shown the necessity of crisis management and the discussion of locating optimal spaces for temporary accommodation, especially green and open spaces after an earthquake to provide assistance and accommodation to citizens. Therefore, the issue of locating, determining urban spaces with the ability of temporary accommodation and providing a suitable pattern of accommodation by considering the effective spatial parameters and factors is considered the most important goal of this research to manage the crisis after the possible earthquake of Tehran in region 3. This research is applied in terms of its purpose and its research method is descriptive-analytical. In this regard, previous studies have been examined using documentary and library studies, a conceptual framework and a review of experiences. This research was done by qualitative and quantitative data analysis and by identifying the criteria and principles of locating temporary settlements and weighting the criteria through a pairwise comparison matrix. Hierarchical AHP method has been used to locate existing open spaces.

The growth of sub-urbanism in recent decades has led to the weakening of inner-city centers and the destruction of the social life of these centers. The most important consequences of evacuation of urban centers are economic recession, population evacuation, unfavorable urban governance, reduced demand for purchases and lack of infrastructure investments. Therefore, the revitalization of urban centers, as the beating heart of cities, plays an important role in improving the quality of residents’ lives. Business Improvement District (BID) is one of the most successful methods with an economic approach to urban centers and is expanding around the world. The aim of the present study is to measure and extract the drivers of improving business districts in District 6 of Tehran with a futures research approach. This research is applied in terms of purpose and uses a combination of documentary and survey methods. Moreover, in terms of nature, based on a new method of future research, it is analytical and exploratory taking a combination of quantitative and qualitative approaches. The statistical population of this study includes 15 managers and experts in the field. The results indicate that the key drivers affecting the creation of business environment in District 6 of Tehran have not been identified. Also, two-dimensional factors such as good urban governance, municipal performance in providing services and facilities, private and public sector investment status, quality of buildings and materials in the housing and construction sector, etc. have a very high capacity to become key players in the system.

Today, beliefs about the impact of buildings and the predominance of man-made environments on architecture and urban planning have become commonplace and many attempts have been made to understand the structure of urban space. High-rise buildings, meanwhile, have an important role to play in creating the mental image of the city through its signaling capacity. This study attempts to determine how physical structure changes in major urban arteries, based on spatial configuration of Tehran's 22th district as a case study and high-rise building positions in it, affect mentality and Environmental perceptions of citizens. The present study is an applied research that aims to combine quantitative and qualitative methods. Space Syntax was used to analyze the space configuration and topological relationships of the paths and three categories of integration, connectivity and intelligibility indices were prepared by using Depthmap software. After mapping the spatial layout factors associated with high-rise buildings, their interconnection type is determined and the final map of the factors is extracted and spatial analyzes and interpretations are performed on them. The findings of the study suggest that high-rise buildings in spaces and pathways have a higher comprehensibility that people with greater eagerness visualize the configuration of the whole space in their minds: There is a more continuous network of routes around them, there are appropriate variations in the length and width of the spaces, and there are buildings of medium height around the roads. Also, high-rise buildings in urban spaces are not individual elements, but rather the relationships between spaces and their relative placement that affect the mentality and perception of the citizens.

Most of the city's viewing corridors induce a sense of confusion to the citizen of Tehran. In these sights and views, there is no harmony. It seems that the main contribution of these disturbances in the face of the city is related to the design and composition of the building masses. This nasty and inelegance image sits in the minds of the citizen that gets addicted to it or gets annoyed because of it. The more hardness is for trained eye that evaluates and adapts the features of these buildings base on the theoretical frameworks, principles, and rules of aesthetics. Research Question: Therefore, the main issue is the reason for this unreliability and getting used to this ugliness, and that how do today's designers and applicants consider the beauty and desirability of city buildings form and their composition? Do the citizens see the city's buildings beautiful? the present study seeks to answer those questions.

 To progress the research, a qualitative research method called the Grounded Theory has been selected. The data is appeared based on interviews with 50 residents of district 2 of Tehran. The interview began with an open question: "How is your neighborhood, place of living, street or alley? Explain it". This preliminary question specifies that whether the interviewees had an experience of visual perception of constructional masses and forms during life in their neighborhood. Further, during the interview and according to the items in each interview, other questions are proposed in the formwork of research issues. Then, the texts of all the interviews have been written, and using techniques of research methodology, analyzed, and their theoretical concepts, extracted and categorized based on their content similarities and differences. In the following, each category of the matched concepts obtained a role in relation to other categories (conditions/context, action/ interactional strategies and consequences) and created a paradigmatic model. And after integratind the categories, deleting additional concepts, completing incomplete concepts, the core category of a phenomenon was identified.

The main categories obtained from the interpretation of the text of the interviews are:Conditional/contextual categories- Merchant urban management- Difference in the type of opinion to the urban development- Emergence of changes in the inhabitants desires and conditions Interactional categories- Visual inconsistency of building masses- Unbalanced combination of building masses with adjacent spaces- Disproportionate size of buildings relative to each other and adjacent spaces- Interest in low-density and low-rise building patterns- Interest in more opened and spacious space proportions- A wish for a less populated place/ a mismatch between space capacity and the dwelling populationConsequential categories- Forgetting about the current time of the living environment- Disconnecting with the living environmentBy reviewing the conceptual content of categories obtained, it seems that the perception and experience of inhabitants of Tehran's 2nd district about the aesthetic aspect of their living environment are visually annoying and unfavorable.What caused of the formation of this experience is the idea of the existence of "merchant urban management", "the difference in the type of opinion to the urban development", "the emergence of changes in the inhabitants’ desires and conditions "; in other words, these cases are the underlying and casual conditions for the formation of this experience. Subsequently, inhabitants in their understanding of the present situation regulate processes in their minds that explain the overall sense of "To perceive inelegance and undesirability from the city". The two main categories of "visual irregularities and distortions" and "shortage of open spaces and a lot densities" play the role of interactional categories in this experience; the categories inhabitants apply to perceive their experience of the living place. Finally, the consequence of the formation of these interactions and processes, or the same general phenomenon (To perceive inelegance and undesirability from the city), emerge in the poor communication of the interviewees with their living environment. The sense of "forgetting of the present time among the regret of the past and the future concern" and "the disconnecting to the living environment" because of the thought for immigration and indifference to the environment, are the consequences of this experience.

The attractiveness of assets to the enemy is an estimate of the value of the target to the adversary. Experience has shown that, especially in military strikes, signs or targets better meet the goals of the adversary than others. Since not all assets are of equal value to the enemy, a basic assumption is that the value of an asset from the enemy's perspective is a factor that affects the likelihood of a security incident. The purpose of this study is to model the radius of vulnerability of land uses with a very high degree of vital importance as a case study in District 6 of Tehran. The type of research is applied and research method is descriptive-analytical and the method of data analysis is Mamdani fuzzy method. To radiate the vulnerability of critical assets, bombs with a warhead of 4,200 pounds of TNT were fired. Besides for very important assets, bombs with a warhead power of 2100 pounds of TNT have been selected according to the FEMA 325 guidelines, and the vulnerability radius in the GIS environment is further specified. The results show that in the event of a missile strike with a warhead of 4200 pounds of TNT from an area of 2120 hectares in an area of 833.27 hectares, equivalent to 39.3 percent and of the total number of land uses in the region, 11869 units, equivalent to 40.84 percent, were affected by the explosion. Also, if a missile with a warhead of 2100 pounds of TNT hits the total area of 906.87 hectares, equivalent to 42.75 percent, and of the total number of parts, 12864, equivalent to 44.26 percent, it will be affected by the explosion. Finally, suggestions for reducing vulnerability are provided.

Urban planning is always heading to optimize using of unused and abandoned lands in order to avoid unsustainability. Redevelopment and reusing of these lands are playing significant roles for urban development. Proper planning could enhance the deficiency and contribute to prepare the needed land uses of cities. The purpose of this study is to determine and evaluate the status of these spaces of Tehran, district 18. First of all, environmental, physical, social and economic consequences of abandoned land was studied. Based on infill development approach and strategic vision, the development process of these lands was explained in local communities. To characterize the abandoned areas, some criteria were identified as indicators for evaluating land use capacity. Out of total 57008 land plots in the region, 15 unified land plots (sand quarries, Shadabad Iron Market, three brick furnace, six abandoned warehouses and four abandoned factories) were determined as abandoned spaces. AHP analysis method was used to the redevelopment plan based on the indicators of sustainable and intelligent development and adapted GIS maps. The results show that the land 1 with 189.8364 hectare is the priority for using in redevelopment planning for Tehran, district 18.

The social pathology of urban neighborhoods is very important in the sustainability of the city. This research studies the sustainable pathology of urban neighborhoods in Region 1 of Tehran city with an emphasis on social harms. The main objective of the social pathology and its spatial distribution at the neighborhoods level is to plan and manage how to control and reduce the social harms and make sustainable neighborhood development. Employing an exploratory analysis method, the present study is an applied research. The data has been collected through documentary and field studies. For analyzing the data, Super Decisions software and various tools have been used in Geographical Information System (GIS). The study area is the neighborhoods of Region 1 of Tehran municipality and the level of analysis is its 26 neighborhoods. The statistical sample consists of 30 experts in the field of urban planning and engineering, and 372 inhabitants of the 26 neighborhoods. These participants have been selected using Cochran Formula and random sampling. The findings of the study show that the neighborhoods of Region 1 of Tehran municipality are encountering growing social harms. Common social harms in this region are ​​divorce, runaway girls, beggary, drug addiction, and seasonal workers. In terms of spatial distribution, mostly squares are densely populated, e.g., Tajrish Square. Among the 26 existing neighborhoods, Evin (rank 1), Zafarranieh (rank 2), and Imamzadeh Qasem (rank 3) Neighborhoods have respectively the most amounts of social harms while Araj, Hekmat, Deszashib, and Mahmoudieh Neighborhoods have the least amount of social harms. Any appropriate social interventions and supportive measures require comprehensive studies and studies on opportunities and threats, the strengths and weaknesses, the nature and causes of injuries and social issues at a smaller level, namely, neighborhoods. According to the results of this study, effective preventive measures can be taken to improve the planning and optimal management of the city of Tehran in the municipality of Tehran, with the full knowledge of the existing damage and its type, and by achieving appropriate strategies to reduce the damage to the neighborhood system. In the area of ​​a Tehran municipality, in order to help improve urban planning and management through the identification and elimination of existing damage, it is possible to develop and improve these areas of the region in terms of the quality of life of citizens and minimize the damage.  In terms of the indices of urban development infrastructures and facilities, significant differences are also observed between the neighborhoods of this region using Fuzzy Method, e.g., Tajrish Neighborhood has the first rank in sustainable development due to the availability of facilities and access to offices and industries and several other development indices. Bagh-e-Ferdows Neighborhood has the second rank, while Golab Darre and Mahallati Neighborhoods are at the bottom of this ranking. According to the results of this study, it is possible to improve the planning and optimal urban management in a Tehran municipality region with full knowledge of existing damage and their type. They have taken effective preventive measures and appropriate.

Today, habitability as a result of sustainable development theory is aimed at reducing the economic, social, physical, and environmental problems of cities and communities based on their needs and capacities. Bioaccumulation follows the principles that are actually components needed to move towards sustainability. Hence, access to a vibrant city is very important. The purpose of this study was to identify and evaluate the indicators and factors affecting the achievement of a sustainable city in urban wasteworn and non-corroded tissues, which is a case study in the 10th district of Tehran. The research method is descriptive-analytical and survey. The statistical population of the present study is residents of Tehran 10th district. To obtain the logical volume of the sample, 384 samples were determined using the Kukaran formula and selected randomly. The main tool for collecting data in this study is a questionnaire. The results of statistical analysis in Spss software show that 10th district of Tehran is unacceptable in terms of urban viability. The findings also suggest that there is a significant difference between urban exhausted and non-corroded tissue in terms of access to the living city

The rapid development of urbanization has had a significant impact on the old and historic nuclei of cities. In other words, these areas have become worn-out and inefficient urban structures compared to other areas of the city, and the most important factor influencing their abandonment is the economic factor which has caused these tissues to lag behind the development process and become the center of problems and failure.In this regard, the metropolis of Tehran is one of the major cities that, under the influence of the rapid development of urbanization, faces risks and disturbances in various dimensions in the old and historical nuclei.The manifestation of these disorders and challenges in the 10th district of Tehran, with a significant area of worn and dysfunctional urban fabric, is 52% more pronounced and more severe and directly or indirectly, it has involved citizens in a wide range of issues and problems. Therefore, this research is based on the process of a new approach to the intervention of the base location in urban dysfunctional and worn-out tissues namely urban sustainable regeneration (with an approach circle economy regeneration) through strategic planning, while analyzing the current situation, the position of the worn-out texture of Tehran’s 10th district in the economic field, pay to provide key strategies for the optimal use of potential facilities and capacities within the context and restore economic prosperity to the range of study tissue. The type of research is applied in terms of purpose and descriptive-analytical in terms of method. The technique used for data analysis is the integrated SWOT-AHP model.The results show that the worn and dysfunctional texture of the 10th district of Tehran in the economic field is facing many weaknesses in terms of internal environment and significant opportunities in terms of external environmen which in finally, by adopting adaptive strategies (revision), it is possible to make the most of the opportunities in the economic field by reducing the existing weaknesses.

Nowadays, with the advent of long distance military weapons, the role of cities has become more important in provide safety in wars. Military threats have continued due to insecurity in the Middle East and the presence of valuable potentials in Iran. Safe urban design, by paying attention to the physical vulnerability of the city against threats, can improve the conditions of cities. It tries to plan new urban development properly or to solve existing problems by identifying appropriate urban morphology from the perspective of passive defense. Obviously, some concepts such as city structure, urban texture, urban form, density, and urban networks can be effective in reducing the vulnerability of the city to military strikes. In this context, it seems that such concepts should be reorganized and redesigned. Observing passive defense considerations in designing and organizing urban facilities can significantly reduce their vulnerability. Moreover, recognizing the characteristics of suitable urban morphology from the perspective of passive defense in new urban development can be a solution for urban security. The purpose of this study is to evaluate the vulnerability of various urban sprawl against air strikes from the point of view of passive defense considerations. As a case study, the 6th district of Tehran has been selected because of valuable land uses, such as ministries, governmental agencies and private organizations. The method of measuring the vulnerability of various urban sprawl against air strikes in this research is descriptive-analytic. This practical research is carried out by collecting theoretical literature review using documentary methods. The survey method with observation, interview and questionnaire is used to achieve this goal. For this purpose, evaluation criteria are extracted by studying theoretical literature of passive defense considerations and urban morphology. These criteria are determined by conducting interviews with experts and were cared for in the Delphi method. The statistical society of this study are urban planners and architects who are proficient in passive defense considerations at relevant universities and organizations. Twenty of them were randomly selected to complete the questionnaire. Then, using the Inversion Hierarchical Weight Process (IHWP), the importance and weight of the criteria and sub-criteria were determined. The GIS software program, by disassembling layers for each criterion, provides the final vulnerability map for the 6th district of Tehran. Due to the objective and scope of the study, it only examines the vulnerability through the map. However, Argentina Square, Kargar Street and the Shahid Ghomnam Highway have high vulnerability in the area due to their high construction density and old age. Generally speaking, it can be concluded that smaller blocks with low shaped compaction, along with large land lots and low occupancy levels of the masses, can be regarded as an appropriate city morph from the perspective of passive defense. Regarding the buildings, low density and newly constructed ones, proper quality and low complexity form are considered appropriate. Moreover, wide streets, confinement, and low-level integration are appropriate from this perspective.

The Meta-Neighborhood Land use congestion, especially in urban and suburban scale can be disturbed by a different function the Neighborhood functions and neighborhood development. The present paper examined this issue with the sustainable urban development approach District 12 Metropolitan Tehran. Research methodology based on descriptive-analytical approach, required data is collected in the library and field and the analysis has been conducted with the help of multivariate regression test (the effectiveness of research variables). The statistical population of the study is the population of District 12 Metropolitan Tehran. It was determined that the sample size with the Cochran formula was 384. The research findings indicate that 30% of the total land use used for residential land use and 70% for non-residential land use Supra-regional -District land use that which are non-residential nature, account for 36/95 percent of the total of the region. As well as, the findings of the research show that there was the urban and suburban land use congestion there was a direct and significant direct effect on the land use density on the neighborhood function. Therefore, one of the most important strategies in the sustainable development of neighborhoods is a balance in the allocation of land uses with "Neighborhood Functionality" and "Urban and suburban Functions"

The spatial organization of urban habitats is a direct result of social, economic, and political processes. The organization of the internal component of a spatial dispersal can be affected. The location of each component is shaped together with each other in conjunction with spatial organization. The main functions of man, especially the economic, social, commercial, and service functions, are through their activities, the vision of the environment takes shape, form and system of its own. Following the prevalence of the ideas of ecosystemism and sustainable development in the world, this attitude gradually penetrated into public opinion and planning that land is not a private commodity. It is also the most important commonwealth and the mainstay of all the activities of citizens and the means necessary to research the aspirations and aspirations of humanity in the present and future. In this regard, the purpose of this research is to analyze and evaluate the utilization of urban lands of the region based on the city's physical divisions and to determine the degree of adaptation of applications. The research methodology is descriptive-analytical And using the documentary and library method to collect information Finally, using multi-criteria modeling techniques, the information is analyzedThe criterion of the relative relative contribution of construction activities due to the destruction and renovation in the whole construction area and the consequences of it with a score of 0.4270 can be ranked first.

This paper presents an approach that attention to the ways in which urban spatial configuration has a distinctive roll in urban landscape perception. Especially in historic urban fabric, configuration draws the ways and represents factors that have transformed urban space during time. In Iran, the physical-spatial transformations have brought about fundamental changes in the construction and configuration of cities. The present study was conducted to investigate the relationship between the city morphology and the citizens’ perception of the urban landscape in district 12, Tehran, Iran. This paper based its main argument around the idea that exist significant relationship between the morphologic properties of the city and the citizens’ perception of the urban landscape. The paper uses some objective methods of spatial analysis to demonstrate how the change of morphology effects on landscape perception. As a configurationally analyses method space syntax approach was employed to evaluate the construction and configuration of the study area. The space syntax method was carried out based on the drawing of axial lines in the UCL Depthmap environment. Also, the survey method and Likert questionnaire were used to analyze the citizens’ perception. Finally, the Pearson correlation analysis was used to evaluate the relationship among the variables. The results showed that the visual and perceptual of the urban landscape has a significant and direct relationship with integration of urban spaces. Also, with moving from edges to depth of urban space, intelligibility and perception of the urban landscape decrease dramatically within the study area. Thus modernization and renovation of the historical fabric has been unbreakable in the continuous reproduction of the landscape.

Natural disasters are amongst main parts of our life and they have been regarded and will be regarded as a permanent thereat to development, in other words human daily life cannot be assumed without natural disasters. It should be taken into consideration that it is impossible to preclude these disasters but to prepare for a good reaction for these disasters can be a good solution to decrease post damages casualties to the cities. Herein, Crisis Management Supportive Bases in terms of prevention, preparation and dealing with the crisis play a key role especially in Tehran and in time of natural disasters. There is no doubt that high level and efficient function of these bases has a striking correlation with the way they are located in both urban and regional level in a way that in addition to providing security of the bases especially versus disasters, they could be, based on the service area, able to provide the areas of crisis with good services. This paper tries to use multi criteria analysis techniques (MCDM) and spatial analysis (GIS) method in order to assess the effectiveness of these supportive bases. Based on assuagements crisis management supportive bases have spontaneously distributed in 18 district and have located in inappropriate places. Their location was chosen without looking after for their own specific needs.

The overall goal of research is to explain the factors influencing vulnerability zoning district 6 of Tehran and vulnerability in the face of natural disaster flooding. According to the study, the criteria for the vulnerability of cities through previous studies, library studies and Delphi method, interviews of experts will be identified. And then fits the criteria, through the digitization process navigation data to the appropriate format to be imported into GIS. To identify relationships between the standards and the structure of the techniques used DEMATEL. The structure can be obtained through questionnaires completed by experts. Because of the importance of parity is not the way to gain weight ANP criteria will be used. In this study, the MATLAB software for the calculation of the benchmark (DEMATEL techniques) and the application of the criteria used to calculate the weight Super decision. For spatial modeling and vulnerability mapping in Tehran from model-based sorting option is based on profiles that it has removed some restrictions on former methods. This model through the design and incorporation of an extension (extension) using the Python programming language to ArcGis software will be operational. At the end of the six different areas of Tehran in terms of vulnerability to natural disaster will flood zoning. The results showed that a sector with high vulnerability in areas with population density and urban fabric, with an area in the South East is on. Without access to areas after flooding in the vulnerable urban fabric is very important.

Urban decay is the process whereby a previously functioning city, or part of a city, falls into disrepair and decrepitude. It may feature deindustrialization, depopulation or changing population, economic restructuring, abandoned buildings, high local unemployment, fragmented families, political disenfranchisement, crime, and a desolate, inhospitable city landscape. Also urban decay has no single cause; it results from combinations of inter-related socio-economic conditions—including the city’s urban planning decisions, the poverty of the local populace, the construction of freeway roads and rail road lines that bypass the area, depopulation by suburbanization of peripheral lands, real estate neighborhood redlining, and xenophobic immigration restrictions. Tehran Metropolitan is confronted with the urban decay problems and urban regeneration is issued as the last policy for reduction of this problem. In relation to this matter 15th municipality urban district has been selected as a case study which contains complex urban decay.Determination of priority of intervention in decayed blocks is basic purpose of paper. Boolean logic, factor analysis and other statistical methods have been used for achieving and fulfillment of those purposes. Outcomes of this paper demonstrate that giving special attention to economic and social criteria with physical factors simultaneously, is essential for determination of intervention type in decayed blocks in 15th municipality urban district.
