Abstract Abstract Background and Aim Land use change modeling is an essential tool for environmental analysis, planning, and management. Among the basic objectives of this research is to investigate and understand the changes in land uses in Region 7 of Tabriz between 2000 and 2020 using remote sensing technology and satellite images. And also to predict these changes for the next 20 years. To predict the changes, the Markov chain cell model was used for prediction. Among other objectives, it can be mentioned to find out the use that has and will have the most changes and increases.
Methodology: Land use change modeling is an essential tool for environmental analysis, planning, and management. The main objective of this research is to investigate and evaluate land use changes in Tabriz city over a 20-year period (from 2000 to 2020). This goal is achieved by extracting land use maps for the years 2000 and 2020 through satellite images and obtaining the changes that have occurred in land use during this period, and finally predicting these changes using a Markov model.
Results and Findings: The results indicated that although the region has a large area of barren land, the residential area has grown significantly between 2000 and 2020 and will continue to grow in the future. This indicates a positive and increasing trend in urban and residential areas that should be taken into account. Between 2000 and 2020, we have witnessed a sharp decrease in green space, which can be a warning for managers and decision-makers. Urban green space is an important land use within the city and on the outskirts of the city, and its absence causes environmental problems and .... Also, residential land use will have the most changes at the regional level for the next 20 years, and it was proven that the maximum likelihood classification model has appropriate accuracy for classifying satellite data.
Conclusion: The overall results showed that although the region has a large area of barren land, the residential area has grown significantly between 2000 and 2020 and will continue to grow in the future, indicating a positive and increasing trend in urban and residential areas that should be taken into account. Between 2000 and 2020, we have witnessed a sharp decline in green space, which can be a warning for managers and decision-makers. Urban green space is an important use within the city and on the outskirts of the city, and its absence causes environmental problems and .... Industrial areas have also enjoyed significant growth in the past 20 years, and the growth of this use and its positive and increasing

Abstract Background and Objective: The smart city, as a modern approach to urban management, aims to enhance quality of life, service efficiency, and sustainable development through advanced information technologies, citizen participation, and data-driven decision-making. This study evaluates and ranks the neighborhoods of Tehran's District 6 based on the development level of smart city indicators.
Methodology: The research is applied in nature and employs a descriptive-analytical method. Initially, smart city indicators were identified through a review of theoretical sources, followed by the development of a specialized questionnaire based on the COCOSO model. Field data were collected from 30 urban planning experts, including university professors and municipal officials, using snowball sampling. The Shannon entropy method was used to determine the weight of each indicator, and the COCOSO decision-making model was applied to rank the neighborhoods.
Results and Findings: Results indicate that Neighborhood 4, with a score of 5.442, ranks first, followed by Neighborhood 5 (5.411) and Neighborhood 6 (5.118) in second and third places, respectively. Neighborhoods 3, 1, and 2 rank fourth to sixth with scores of 4.099, 3.322, and 1.447, respectively. The findings suggest that balanced smart city development in this district requires targeted policymaking, enhanced digital infrastructure, and leveraging local capacities in each neighborhood.
Conclusion: These results highlight that utilizing local advantages, particularly in lower-performing neighborhoods, can significantly contribute to improving smart city indicators and reducing spatial inequalities.

Abstract Abstract
Forecasting the Trend of Housing Price Changes in Ardabil with a Spatio-Temporal Analysis Approach examines the spatial and temporal dynamics of housing prices in this city. In recent years, housing price fluctuations have become one of the most important economic and social challenges in the city of Ardabil, which necessitates a deeper understanding of its change patterns. This research seeks to answer the question of how different spatial and temporal factors affect housing price trends in different regions of Ardabil. The main objective of this study is to predict future changes in housing prices using modern spatio-temporal analysis methods and identify areas with potential for price growth or decline. The research method is a combination of advanced statistical analysis and Geographic Information System (GIS) with an emphasis on Geo-Temporal Weighted Regression (GTWR) models. The data used include housing price information over a 5-year period and effective environmental, economic, and physical variables. The findings show that housing prices in Ardabil follow a spatio-temporal cluster pattern and the central and northern areas of the city are increasing in price at a faster pace. Key influencing factors include access to service centers, quality of the urban environment, inflation rate, and population growth. The results show that by 1405, neighborhoods adjacent to administrative and commercial centers will face price growth of 25 to 30 percent. This study provides a valuable tool for urban policymakers and housing investors to make more informed decisions in urban planning and investment in the housing sector.

Accordingly, the present study was designed to assess the desirability of the quality of residential environment components from the perspective of citizens in the city of Baqubah, Iraq.
Methodology: This research is applied in terms of purpose and descriptive-analytical in terms of type. The statistical population includes the citizens of Baqubah city and the sample size was determined to be 384 people using the Cochran formula. SPSS software was used to analyze the data and in this regard, one-sample t-tests, independent t-tests, one-way analysis of variance and Scheffe's post hoc test were used.
Findings and Conclusion: Based on the results of the one-sample t-test, the level of satisfaction of residents with their residential environment shows the number 3.548. In addition, one-way analysis of variance indicates that two factors, age and education level, have significantly affected the level of satisfaction of individuals with the residential environment. In contrast, factors such as employment status, income level, home ownership, distance from work to home, house area and number of rooms have not shown a significant effect on satisfaction with the residential environment. Surveys show that the level of satisfaction of Baqubah residents with the residential environment, according to evaluation criteria including security, public facilities and services, physical features, visibility, lighting and ventilation, community health, access and transportation, and neighborhood relations, is generally assessed as average.

Abstract Perhaps one of the biggest and most dangerous diseases for urban life in the current century is the Covid-19 pandemic. Spatial pattern analysis and risk analysis is a suitable tool in the diagnosis and weather of epidemics and can be understood and help public health diseases. Spatial analysis methods of Geographic Information System (GIS) were used to examine the relationship between the initial statistics of the Covid-19 virus data and the analysis and analysis of spatial patterns in 62 neighborhoods of Khoy city. Therefore, using spatial statistics analysis tools, the spatial distribution pattern was examined and analyzed. The research method is descriptive-analytical; the aim of this study is to use spatial statistics methods to analyze and analyze the use of the Covid-19 spatial virus from the beginning of 2010 to the end of 2023. In order to analyze and analyze spatial patterns, spatial autocorrelation statistics, Moran cluster analysis, global local cluster analysis and identification of hot spots were used. The spatiotemporal pattern showed that the global Moran autocorrelation is highly clustered and less than 1% is likely to be a random cluster pattern. Local Moran autocorrelation statistics for hot and cold spots showed that the northwestern neighborhoods of Khoy city have a high-high clustering (aggregation) feature and the neighborhoods of the western part of Khoy city are hot spots with a 99% confidence level and the southern neighborhoods in the Valiasr township are cold spots for COVID-19 with a 99% confidence level. Comparison of multiscale geographic modeling with other models showed that apart from the performance index with a negative effect; the social and economic, environmental, communication network and physical indicators have a positive effect. Results The degree of dependence index (DOD) of the research data improved with 90% spatial dependence and the R^2 coefficient from 58% to 64% in the multiscale regression model.

Abstract Background and Objective: The contemporary world, marked by rapid transformations, requires dynamic indicators to promote justice-particularly in the fair distribution of urban services and facilities. Due to ongoing inequalities in developing cities, recent academic and institutional efforts have focused on urban models that integrate social justice to achieve sustainable development and improve the quality of life. Within this framework, the City Prosperity Index (CPI) has emerged as a key tool for evaluating justice across various urban dimensions. This study aims to assess the ten municipal districts of Tabriz in terms of their social justice performance, as one of the five main dimensions of urban prosperity.
Methodology: To achieve the research objectives, five criteria and indicators were employed, considering data limitations and the lack of official statistics. The spatial scope covers the ten municipal districts of Tabriz. The PROMETHEE and GAIA models were applied for ranking and analysis, while the ANP model was used for weighting the indicators. Geographic Information System (GIS) tools were also employed to visualize spatial patterns and disparities among districts.
Results and findings: The results of analyzing the social justice index across the five sub-criteria in the ten districts of Tabriz indicate that District 6, with a net Phi value of 0.400 and a score of 100, ranks first in terms of social justice performance. It is followed by District 2 (Φ = 0.178, score = 61.39). Districts 1, 5, and 9 fall within the medium level of social justice, with corresponding Phi values of 0.156, 0.133, and 0.044. In the low-performance range are Districts 8, 4, 3, and 7, with Phi values of –0.044, –0.067, –0.178, and –0.200, respectively. The lowest rank belongs to District 10, which demonstrates a highly unfavorable condition in terms of access to social justice–related services and facilities. Among the ten districts of Tabriz, only Districts 6 and 2 occupy high or very high positions in terms of social justice, whereas Districts 8, 4, 3, and 7 exhibit poor conditions, and District 10 shows a very poor status. Therefore, promoting balanced urban growth and reinforcing the driving factors of social justice should be prioritized by urban planners and decision-makers in Tabriz.
