The Kan-Soleghan basin is located on the southern Hillside of the Alborz, which has affected the Alp-Himalayan active zone over time. In this respect, the evaluation of active tectonic processes and their effects on many human activities, such as the design and construction of cities, powerhouse, dams, and industrial facilities are of great importance. The passage of the Tehran-North Freeway Tunnel from the area increases the activity of the faults that contributed to the formation of the current morphology of the basin. In this research, morphotectonic indices including river asymmetry index (Af), basin shape (Bs), hypsometric integral (Hi), Stream length index (Sl), mountain front sinusity (Smf), valley width to valley height (Vf), topographic symmetry (Tp) was calculated. Finally, the mean of the results of the indices was calculated as the LAT index. In the present study, topographic Map 1:50000 and digital elevation (DEM) maps with 30 m spatial resolution (ASTER sensors), the boundary layer of the basin, were used to calculate morphometric indices. The Kan-Soleghan basin area is divided into three tectonic regions with slow, semi-active, active Tectonic, and the calculation of the relative active tectonic (LAT) index indicates that the studied area is in tectonic terms in active state. The tectonic structures, especially the faults of the region, have affected the asymmetry and shape of the basin. The main river Kan-Soleghan also shows asymmetry, which can be said due to the structural factors, especially the faults of the region, the basin has asymmetry and deviation to the left of the basin. Also, the construction of the Tehran-north freeway and the location of the Tunnel openings in the vicinity of the northern fault of Tehran, is one of the human factors influenced by the tectonic activity of the area, which requires tectonic activity.

Also, studies indicated that the cumulative variance explained by the relevant factors in the study sample is about 69.879, which explains the development of a model of a creative urban area in the 11th district of Tehran and represents 70% of the model realization based on the social capital approach.

Social sustainability today, as the most important dimension of sustainable development, has an important place in urban planning and its importance in planning is constantly increasing with the increase of social problems and divergence between neighborhoods in terms of performance and participation. Therefore, this requires more research in urban studies. This study was conducted to investigate the role of social participation in the development of social sustainability in neighborhoods. For this purpose, the significance of the significant effect of these two variables has been measured. The research is applied in terms of purpose and descriptive-analytical in terms of method. Data collection was library and field method. The statistical population of the study consists of a group of experts who were selected by the available method of 20 people as the sample size of the study. Data collection tool is a questionnaire based on theoretical foundations and studies conducted on a five-point Likert scale. Data analysis was performed using structural equations with the help of Emus software. The results showed that the social participation of citizens in neighborhoods with a coefficient (beta) of 0.732 has a positive effect on sustainable social development of these neighborhoods and the relationship between these two variables is significant. In other words, sustainable social development will be strengthened by strengthening social participation. And the variables of sense of belonging, satisfaction with the neighborhood, participation in neighborhood activities and trust also have a positive effect on the variables of social participation in neighborhoods.

One of the theories that studied poverty and inequality after World War II and urban reconstruction in America in the duality of the suburbs and the central city is the theory of Spatial Mismatch. Despite the role of the background caused by racial-ethnic inequality and the contrast between the suburbs and the central city in the formation of the aforementioned theory, the main indicators of Spatial Mismatch indicate the lack of appropriateness between obtaining a job with sufficient benefits to access affordable and quality housing. This means that the backgrounds, structures and processes of inequality are different from one society to another and the lack of proportionality between the benefits of work and access to housing represents the spaces of poverty. The aim of the current research is to reveal the Spatial Mismatch between the two mentioned indicators in the metropolitan areas of Tehran. The current research is applied research in terms of its purpose and descriptive-analytical in terms of its method. The main data required include major occupational groups and housing status in official population and housing censuses, which have been analyzed using spatial functions. The analysis of the research findings shows that there is a direct relationship between occupational stratification and the quality of residence in Tehran's municipal areas. In such a way that the concentration centers of the lower classes and workers who are deprived of jobs with suitable benefits have been formed in residential areas with poor quality and worn-out textures. Based on this, in the southern regions of Tehran, there is a greater disproportion between getting a suitable job and access to quality housing. While in the northern areas of Tehran, there is much more suitable work and access to quality housing. The final result shows that the two main indicators investigated well reveal and represent the «Spatial Traps of Poverty» which are the main focus of Socio-Spatial Issues in Inner City Areas.

Housing design plays a crucial role in sustainable social development as cities face numerous challenges due to various changes in the physical landscape. Therefore, it is imperative to establish appropriate design indicators for residential towers. This study aims to investigate the design indicators for sustainable social development in residential towers in the metropolis of Tehran. The research method employed is descriptive-analytical and applied in nature. The statistical population for this study consists of architectural experts who are members of the Tehran Organization. According to the Engineering System Organization, the statistical population comprises 22,000 experts and members of the Tehran Engineering System Organization. The sample size was determined to be 384 individuals based on the Morgan table. The results of the Friedman test indicate that designing open spaces for art, culture, games, and entertainment in towers promotes interactions and a sense of belonging, while mitigating the negative effects of industrial life on residents. This aspect was found to have the highest weightage of 17.81. Additionally, the flexibility in tower design and overcoming structural constraints through solutions such as strip design and atrium design, along with facilitating proper access and installation of open spaces, contribute to sustainable development and enhance residents' satisfaction. This indicator obtained a weightage of 17.51. Furthermore, the effective management of towers and the design of suitable social spaces on roofs and ground floors (interactive, sports, cultural, and artistic) have a significant impact on reducing tower-related issues and promoting vitality and public participation. This indicator ranked third with a weightage of 17.42. Consequently, sustainable social development is closely linked to the design of residential towers.

The rapid and ongoing trend of metropolises transitioning into global cities and world cities is influenced by the increasing political, economic, cultural, and scientific dimensions of the urban political geography. Cities, as dynamic entities, evolve from new cities to mother cities, metropolises, global cities, and ultimately world cities. In this competitive environment, metropolises strive to enhance their level of competitiveness vis-à-vis their counterparts. In this study, the researcher compares the performance of Tehran and Istanbul, two metropolises in the Islamic world, based on the criteria and functions of world cities. The researcher employs an index developed by political geography scholars who specialize in studying world cities. The objective is to determine the ranking of these cities among world cities. To accomplish this, relevant maps have been prepared using ArcMap software, and numerical indicators and criteria have been analyzed in a descriptive-analytical manner. The analysis reveals that Istanbul outperforms Tehran in most indicators and occupies a strong position in the network society and flow space of global cities. This can be attributed to factors such as geopolitical location, an open economic environment, and other indicators. The results of this comparative study can guide city administrators in designing a more suitable future landscape for these cities, ultimately leading to achieving global city status.

In the age of knowledge, the rapid development of information and communication technology is considered as the main element to respond to the increasing urban environmental and socio-economic crises. Therefore, knowledge-based cities are cities that use technology and innovation to improve the quality of life of citizens and the efficiency of services aimed at sustainable urban development. Based on this, the current research was compiled with the aim of the impact of ICT use and capability on knowledge-based urban development. The research method is applied in terms of nature, in terms of the type of descriptive-analytical research (Structural Equation Modeling) and in terms of the type of post-event strategy. The method of data collection was library and field. The statistical population includes the experts of the Deputy of Urban Planning in 22 districts of Tehran Municipality, and the sample size was determined by targeted sampling of 220 people. Structural equation method and partial least squares approach and SmartPLS3 software were used to analyze the research data. The results indicated that the average variables of application and capability of information and communication technology and knowledge-based urban development of Tehran, along with all its components based on a 5-level spectrum, are in the range of 2.51 to 3.5, i.e., semi-stable. Also, the effect of the application and capability of information and communication technology on knowledge-based urban development has a significant coefficient greater than 1.96, and the path for the main research model is confirmed; Therefore, taking advantage of the application and ability to invest in the research and development of information and communication technology sectors can be a solution to remove the limitations of knowledge-based urban development in the metropolis of Tehran.
