Abstract Extended Abstract Background and Objectives: The dynamic and rapid growth of urbanization and, as a result, the physical changes in cities have led to many challenges and problems. Physical development is manifested in varied forms, ranging from scattered to dense and intelligent. Each form of development has its advantages and disadvantages. Accordingly, without proper planning and consideration of the existing context, unmanaged city growth can cause direct and indirect harm to the urban environment, with citizens and resources being the primary victims and potential future heritage. Iranian cities have also contributed to this global experience based on many variables, such as demographic, social, and economic movements. In the meantime, the historical city of Yazd, as a precious legacy of its predecessors, has experienced a coherent and sustainable form of development by relying on creativity and initiative. The physical structure has been transformed into different types in the last few decades. Continuing this situation not only disrupts the city’s physical cohesion but also exacerbates the economic, social, and legal issues. Therefore, the present research seeks to answer whether the findings of different models in the analysis of the physical development pattern in Yazd City yield a unified result or deviate from one another.
Methods: The current research is an applied research in terms of purpose and adopts a descriptive-analytical approach. The data and information required for analysis in the research have been collected through bibliographic and field studies. Aligned with the research objectives, the study employs quantitative analytical models, namely Shannon entropy, Heldren, Moran’s coefficient, and a comparison of filled and empty urban land. Additionally, multi-time satellite images have been incorporated to analyze the data and investigate the physical development pattern of the city.
Findings: In this research, various quantitative analytical models such as Shannon’s entropy (2006-2021), Heldren’s (1996-2016), Moran’s coefficient (2006-2016), comparison of full and empty urban land (1398) and multi-temporal satellite images in the period 1990-2000-2013 and 2021 have been used to study the physical development pattern of the city. The results of the study of the city’s physical development using multi-temporal satellite images in 1990-2000-2013-2021 indicate a 71.46% growth of the city during these 31 years. Contrasting Shannon’s entropy model between 1385 and 1400 reveals the city’s dispersed growth over the 15-year period. In accordance with Heldron’s model, using 1345 as the starting point and 2016 as the endpoint, it is observed that 59% of the overall physical development or city size increase is attributed to population growth, while the remaining 41% is linked to the scattered development of the city. The findings from the comparison of Moran’s coefficient in 2006 and 2016 indicate a shift in the spatial distribution pattern of Yazd city’s population density, transitioning from a random pattern to a scattered one. Additionally, when evaluating the ratio of dense tissue area to the total city size in Yazd (coefficient 0.015), the comparison reveals that the growth rate of the city area corresponds proportionally to the growth rate of the population during the specified period.
Conclusion: The results of all these methods indicate that the city of Yazd experiences scattered and unbalanced physical development. According to the results of the study, Yazd City is located in an area where the town’s per capita services and facilities are high, with a large volume of services that can serve twice its population. Examining the results, it becomes evident that in Yazd City, the speed of inactive urban levels increases in favor of the active groups as one moves from the central area to the surrounding regions. These functional levels not only exhibit significant potential for internal development but also present a viable option to prevent the sprawling expansion of the city.

Abstract Extended Abstract
Objective and background: The growth of population in cities and urbanization has led the managers and urban theorists to find possible and correct solutions for urban development. In 1980 and 1990, the redevelopment of abandoned lands was raised in the subset of the infill development policy. The policy addresses the redevelopment of zones within cities that are polluted, battered, abandoned. These zones have different potentials, such as access to urban equipment and facilities. In practice, the redevelopment of these lands may be associated with challenges such as the type of ownership, accessibility, and economic viability, etc. Measuring and ranking their redevelopment capacity can be an important planning step in returning these lands to the urban development cycle. In the past, Yazd city had some factories and active industries that are now located within the city due to the urban growth and expansion. Currently, these sites are abandoned and have environmental pollution. These sites lead to many social, economic, environmental, and landscape issues. These issues include reduced social security, lack of a sense of belonging, reduced desirability for settlement in these lands, devaluation of land, adjacent municipal waste disposal sites, unpleasant urban image, and spatial discontinuities. Therefore, the main purpose of this paper is to evaluate the redevelopment capacity of the abandoned lands (former Manufactory - Industrial Lands) in Yazd city.
Method: This research is an applied type of research. The research employs a descriptive-analytical research method, and the data is collected by bibliographic study and interviews. Delphi, ANP, Super Decision, and Arc GIS software were employed for data analysis. In the first step, the criteria and the indices are extracted from theoretical literature. The criteria and indices have been scored by Delphi method, and accordingly, the weight of each criterion is defined by the ANP method in the Super Decision software. In the next step, industrial zones of Yazd city were recognized on the basis of weighted criteria in Arc GIS software. Finally, Yazd industrial zone redevelopment capacity has been achieved in 5 classifications (very high development capability, high development capability, medium development capability, low development capability, and very low development capability).
Findings: According to the results of the network analysis process in Super Decision software, the following criteria are prioritized: 1-Site physical status with 0.451 coefficient of significance, 2- Economy with 0.387 coefficient of significance, 3- Infrastructure with 0.161 coefficient of significance. Respectively, location in the city (0.223), owner willingness or activity status (0.220), access to a network of passages (0.118), quality of buildings (0.117), area (0.114), ownership (0.094), price (0.036), access to public transport (0.033), burnout status (0.027) and access to utilities (0.013) are significant sub-criteria. The results show that the lands in the middle and central texture of Yazd have very high and high development capability, which indicates the importance of the location in the city. The lands that have the highest redevelopment capacity have the best access to the pathways. Therefore, location in the city, owner willingness (activity status), access to passages and areas are of high importance. Also, the low ratio of highly developed land area to total land area (35.8) indicates the low redevelopment capacity of manufactory-industrial lands. These results can help urban planners and managers prevent unnecessary growth and expansion of the city in the future and mitigate the low density and urban dispersal.
Conclusions: Redevelopment of lands is a complex and multidimensional process in environmentally deprived sites with urban facilities and infrastructure. This process requires supportive laws and regulations, social participation of owners, citizens, and attention to outreach projects. Most redevelopment projects are costly at first, but if redeveloped to suit the site's features properly, it will bring economic benefits in the long run. This approach can respond to the cities' need for growth and development due to population growth and urbanization and inappropriate use of urban land, leading to good land management. It can also bring vitality, dynamics, social identity, and quality of life back to inefficient urban areas and contexts.

Abstract During the past decades many design strategies have been used in urban spaces of Iranian cities to increase the inclusiveness of these spaces. But still, there are some problems and worries that many groups such as elderly citizens have when it comes to urban public spaces. One of the principles necessary in providing comfort for users of urban spaces is prompting environmental security. The pleasance of an urban spaces depends, on one hand, on being protected against danger and physical injury and, on the other, on mental protection against insecurity and fear of crime. The purpose of this paper is to evaluate the effects of physical components of Khan square as an urban space on sense of security in old citizens. A total of 200 people with the age of 55 and above participated in the survey. The research method used is survey type which is a type of applied study in which techniques such as library documents and references as well as Kolmogorov-Smirnov test, multiple regression and Pearson's Correlation Test are used. Findings of the research indicate that components such as security, light and urban texture have the most effect on the sense of safety in urban space.
