Today, the old fabric of cities has been severely dominated by unwanted developments due to increased construction and dependence on vehicles. This issue has caused many problems in urban issues. Therefore, physical reorganization plans are on the agenda as a solution to reduce these problems. Imam Street, which is located in the old part of Urmia, is one of the main and important streets of the city. One of the proposed projects in the strategic plan of the worn-out structures of Urmia city was the project of organizing and urban design of Imam Street, most of which has been implemented. The purpose of this study is to investigate the efficiency of physical organization projects in the old part of Urmia. The research method is descriptive-analytical and the obtained data were collected through a researcher-made questionnaire. In order to analyze the data, one-sample t-test in SPSS program and also structural equation modeling using AMOS software were used. The average obtained from the T-test in measuring the satisfaction of businessmen and residents located in the old part of Urmia, which was more than 3, indicates that people living in this area and market acquisition are satisfied with the results of physical organization projects.

From the time of human life until now, disasters have had a negative impact on human life; In response, individuals and communities are trying to mitigate the consequences of these disasters and establish scales to assess the initial effects; Also respond to the post-disaster needs and return to baseline. To address these challenges and, as a result, improve the quality of life in cities and metropolises, the need for long-term planning and decision-making in solving these problems is more necessary than ever. Therefore, dealing with new urban theories, each with the aim of solving urban problems, improving the quality and quantity of life of citizens in cities, improving the quality of the city environment, city management, advancing the city to become more desirable, and so on. , Is more important than ever. In recent decades, to solve these challenges and reduce its effects on metropolises and large cities, various solutions and perspectives have been proposed, one of which is to pay attention to the concept of resilient city. The present study is descriptive. - It is analytical and practical in terms of purpose. The statistical population of this study consisted of experts and professors familiar with the topics of the city. 35 university professors and experts in the field of research determined the sample size intended to complete the questionnaire. The results of this study showed that the criterion of physical characteristics of tissue with the highest D-R value (0.672) is at the top of the chart and shows that this criterion is the most effective criterion. Also, based on the calculated D + R value, the building quality criterion is the most important criterion. Also, the urban infrastructure criterion was considered as the most influential criterion due to the fact that it has the lowest D-R value.

Nowadays, addressing approaches such as livability for today's cities as concepts that play an important role in reducing social, economic and environmental problems of cities is an inevitable necessity. In fact, livability is a concept with all angles and mental and objective dimensions Is concerned with human beings and seeks to create a healthier and more livable urban environment for current citizens of future generations; Therefore, livability is a new concept and approach in the paradigm of sustainable urban development, which some consider one of the greatest ideas of urban planning in modern times. In livable city, the goal is not only to meet the physical needs of urban society, but also to create a sense of citizen satisfaction According to this, the main purpose of this research is an analysis of urban livability in Bojnourd with emphasis on security index.

Recognizing and measuring the quality of life in urban areas that are the result of the actions of urban management and other public and private institutions is a very vital issue. Due to the lack of quality of urban life in informal urban settlements, it is possible to provide a roadmap for urban management and awareness of responsible institutions of the current situation and action to achieve the desired situation. The purpose of this study is to assess the quality of life in informal settlements in Miandoab. The research method is descriptive-analytical and based on data collection in the field through a questionnaire. The validity of the instrument and its reliability were confirmed by Cronbach's alpha greater than 0.70. The statistical population of the study consists of 11545 citizens living in informal settlements in Miandoab. The sample size was determined based on Cochran's formula, 313 people. The test results show that four indicators of social, economic, physical and environmental quality of life in informal settlements of Miandoab were significant at a level of less than 0.05. Examination of the direction of significance indicates the inappropriateness of the indicators. The ANOVA test also confirmed that the 10 neighborhoods studied in terms of social, physical and environmental indicators are significantly different at the level of less than 0.05, but in the field of economic indicators (significance level equal to 0.094) there are the same conditions. Assessing the effect of urban management on improving the quality of life through structural equations also confirmed that the rate of explanation for the social index is equal to 0.97; For economic index equal to 0.48; It is equal to 0.93 for the physical index and 0.55 for the environmental index. Therefore, the greatest effect of urban management is on the social index and then the physical.

Due to the many complexities, housing planning, especially for vulnerable groups, in a city as large as Tehran, requires a model to simplify the process and speed up calculations, which does not currently exist. With the aim of solving this problem, the present study proposes a model with the following steps: 1) Explaining the objectives 2) Estimating the housing needs of the target community 3) Identifying expandable areas 4) Proposing construction patterns 5) Proposing dispersion patterns 6) Calculations and patterns Financial and 7) suggest operating patterns. The information required to implement the model was collected from two questionnaires and data from the Statistics Center. In this model, three housing models with minimum, optimal and average areas and three types of existing housing construction, 100% infrastructure and freeing up the yard space were used as public urban space. The proposed zoning was adapted to the 22 districts of Tehran Municipality due to compliance with the available data. Sales price and financial calculations were calculated based on the internal rate of return of 20% and contract subsidies, and finally 4 free transfer models, lifelong lease, lease on condition of ownership in the program areas were proposed. The results show that one of the problems in this sector is the lack of appropriate decision-making structure and planning tools that can provide a comprehensive and complete review of the current situation, comprehensive and comprehensive solutions. Therefore, according to the model and using the indicators used, regions 2, 6 and 13 have the lowest and regions 19 and 22 have the highest potential for housing development of low-income and vulnerable groups, and finally, the model has suggested the most housing in regions 22, 4, 19 and 11.

One of the problems of the cities around the capitals in the third world countries is that urbanization overtook urban development and this issue has created many problems in these cities. The lack of characteristics such as transparency, accountability, rule of law, participation, efficiency and the like in the urban management system also adds to the severity of the issues. The aim of the present research is to investigate the quality of urban physical-spatial development management with a good governance approach and to provide optimal strategies for the city of Shahryar. The research method is descriptive-analytical in terms of developmental and practical purpose, and descriptive-analytical in terms of nature. Data collection was done based on documentary and survey methods, and the tools of interview letter and questionnaire were used. Descriptive and inferential statistical tests, MICMAC software and SWOT model have been used in data analysis. The statistical population includes the city's citizens and the group of experts. Validity assessment was done using construct validity and reliability assessment using Cronbach's alpha method. The results show that the overall average status of physical-spatial development management in Shahryar city from the point of view of good governance indicators is equal to 2.006, which is in an average situation based on the Likert spectrum. The findings of the investigation of the influential factors on the quality of governance of this city with the help of MICMAC software show the stability of the system. Finally, the examination of the strategies for realizing the model of good governance in the urban management system shows the predominance of the strategy (Strengths and threats) in the urban management system of Shahriar, which is based on increasing the level of supervision, developing the capacity of the audit system and the headquarters to fight against corruption and violations. The administration emphasizes the fight against mafia and lobbying in urban management, the development of plans and programs for the renovation of worn-out city structures, the development of electronic technologies and tools, and the improvement of economic and human indicators of urban management.

The concept of regional resilience is one of the prominent concepts of the recent approach to resilience that has been emphasized by various researchers to deal with various regional crises, including flood risk crises. However, despite the research that has been conducted, there has not been the necessary coherence and continuity in identifying the components of regional resilience. On the other hand, in the various categories presented, the ranking and priority between the components of regional resilience have not been determined in general. The present study has reviewed the research conducted with the aim of identifying the components of regional resilience and achieving a reliable model. Therefore, to answer the questions 1. What are the main components related to regional resilience? and 2. Which of the components of regional resilience is most effective in dealing with floods? the meta-composition analysis method has been used. Thus, in the first stage, relevant articles were selected and validated between the period 2015 and 2023; Then, using various coding methods, regional resilience indicators were identified and categorized. This categorization was based on three principles of researchers’ theoretical knowledge, expert opinion, and an overlapping approach. The results showed that six economic, social, cultural resources, geography, physical infrastructure, and resilience components were identified as the main components of regional resilience in the face of flood risk. Also, in order to rank and determine the priority among the identified components, DEMATEL analysis and ISM interpretive structural complementary analysis were used. The results of these analyses showed that the economic component, as an independent variable with a higher level of influence, had a greater impact on other elements of the system in the face of floods. Also, in the analysis of intermediary (connective) components, the resilience component was ranked first. Given that the two components of economy and resilience have had a higher level of impact as independent and mediating components, respectively, it is necessary to emphasize economic resilience as the first priority of regional resilience programs to accelerate regional resilience programs and, as a result, provide greater capacities to deal with flood risk.
