This research has been conducted with the aim of comparing and ranking quality of life indicators with an emphasis on the concept of social justice in heterogeneous urban neighborhoods in Golestan and Choneibe neighborhoods in Ahvaz city. This article is descriptive and analytical in terms of method and practical in terms of purpose. In order to carry out this research, at first, indicators related to the concepts of quality of life (social, physical, economic, and service) and social justice (educational-cultural, health care, administrative, policing, and leisure time) were extracted and items were defined for each. In the second step, researcher-made questionnaires were designed and 380 samples were distributed among the citizens of the study area based on Cochran's formula and random sampling method, and the results were extracted. The statistical analysis of the data was done using the independent T-test and showed that Golestan neighborhood is significantly higher in all dimensions of quality of life (with a total average of 3.85) than Choneibe neighborhood (with a total average of 2.47). Also, in the examination of various indicators of social justice, Golestan neighborhood with total average of (3.79) is significantly higher than Choneibe neighborhood with total average of (2.39). In addition, the results of Indicators ranking using the SAW model showed that the observed differences are mostly in physical, economic and social dimensions.

Cloudiness is one of the most important climate elements that plays a major role in the rainfall and water balance of any region. In addition, the radiation budget of each region is largely controlled by the cloudiness and cloud characteristics of each region. Knowledge of the temporal and spatial structure of clouds in each region plays an essential role in planning and checking programs based on water and energy resources. The main goal of this research is to analyze the temporal-spatial structure of cloudiness in Khuzestan province using gridded data of ECMWF cloud database version ERA5 in Khuzestan province during the statistical period of 1990-2020. The cloud data for Khuzestan province in NC format was obtained monthly from the Copernicus integrated climate database, which included the height of the base or cloud floor, the percentage of sky cloud cover by the upper, middle and lower clouds of each pixel was 0.25 degrees of arc. . By calling the mentioned data in the ARC-GIS environment and spatial averaging by separating the cold and warm periods of the year, 30-year average maps of the warm and cold periods of the year were produced for the two factors of total cloudiness and cloud base height. On the other hand, the sky cloud percentage values were also calculated through spatial averaging in Khuzestan province for each year (1990-2020). The results showed that, firstly, in both hot and cold periods of the year, the northeastern and mountainous parts of the province had higher cloud cover than the plains and lowlands of the province. In the cold period of the year, the percentage of cloudiness of the sky varied between 25 and 60%, while in the warm period of the year, the percentage of sky cloudiness reached less than 5%. In addition, it was observed that in the province of Khuzestan, the highest share of cloudiness in the cold period of the year is related to the upper clouds (cirrus family including cirrus, cirrustratus and cirrocumulus with a height of more than 4 thousand meters). These clouds have a share of 25% in the cloud coverage of Khuzestan province during the cold period of the year. Meanwhile, middle clouds (alto family clouds including altocumulus and altostratus) have a 16% share in the cloud cover of the sky of Khuzestan province. In terms of the cloudiness time series trend during the period of 1990-2020, despite significant annual changes in the amount of cloudiness of the province's sky, no significant trend was observed in the changes of cloudiness in Khuzestan province during the last three decades.

The present research was carried out in the newly founded city of Elhaei, Ahwaz township (2012) with the aim of measuring the degree of success of previous plans (conducted plans) in terms of achieving goals and extracting the most important obstacles, after inferring non-fulfillment of the previous plans. The SWOT and QSPM models have been used to determine the appropriate strategy to achieve the goals of the new plan (master plan). The method of carrying out this research is descriptive and analytical and it was done by relying on documentary studies and field observations (interviews and questionnaires) by experts of housing and urban planning departments and municipalities. The findings of the t-test at a significant level (0.05) show that this plan has not reached its goals in all five main indicators. Among the 12 indicators defined under the title of obstacles, two indicators (weakness of management factors) and (lack of transparency in land ownership and disproportionate allocation of land uses) have had the greatest impact on the project's failure. Also, in the field of management factors, among the 10 defined items, the weakness of specialized human resources with an average of 3.73 and the lack of allocation of credits to projects with an average of 3.61 have had the greatest impact. In relation to the index of land ownership and determine optimal uses, the item of non-implementation of approved laws with an average of 3.59 and the item of lack of proper communication between consulting engineers and city managers with an average of 3.55 had the greatest impact. Also, based on the SWOT and QSPM models resulting from the review of the joint opinions of housing and urban development and municipality experts, the first priority, the conservative strategy, has been introduced.

The main purpose of the current research is to measure the comfort level of public primary schools in Karoun town based on Mahani and Gioni bioclimatic index. In this research, the meteorological data of temperature, precipitation, humidity and prevailing wind in a period of 30 years (1988-2018) have been used. The graphs are drawn with Climate Consultant and Excel software, and the maps are drawn with ArcGIS software. The results of the monthly index tables show that from June to August (3 months), the A1 dry index conditions prevail, which indicates the high fluctuation of daytime heat (more than 10 degrees Celsius) and low relative humidity, which causes discomfort. To solve this problem, it is suggested that materials with medium to high heat capacity should be used in the design of buildings. On the other hand, in the months of June to August (3 months), the A2 dry index prevails, which indicates warm or moderate nights with relatively low humidity in the environment. For the months of December, January and February (3 months), the A3 dry index prevails, which indicates cold climatic conditions in the region. To deal with these conditions, it is necessary to use energy to heat the interior spaces of buildings. Of course, the studied area does not fall under the conditions of H1, H2 and H3 humid conditions in any of the months of the year. Also, according to the results of Giuni's method, in three months of the year (June, July and August) the changes in air thermal conditions is completely out of comfort zone. In September, the weather is comfortable only for a short period of time (midnight to before sunrise). The final control of the building's air, especially during the hottest hours of the day in the months of May to August, is only possible by using air conditioners. According to the studies carried out and their compliance with the school construction standards of the country and taking into account the climatic conditions of the region, the results show that the necessary standards for the construction of schools in the study area and taking into account the climatic conditions of the region are not considered and all the studied schools do not have the necessary standards.

The purpose of this study is to optimally locate educational facilities, enhance their efficiency, and take a significant step towards improving the quality of education.

This research is applied-developmental, follows library and descriptive-analytical methods, and uses Geographic Information Systems (GIS) and the Analytic Hierarchy Process (AHP) model. The 11 selected criteria in this study were categorized into three groups: compatible, semi-compatible, and incompatible. The criteria used in this research included cultural centers, religious sites, sports facilities, green spaces, fire stations, medical centers, military sites, pathways, administrative areas, commercial areas, and urban facilities. To carry out this research, a matrix was first created using pairwise comparisons and AHP. Then, raster layers for these criteria were prepared and standardized from 1 (very unsuitable) to 5 (very suitable). Finally, each raster was multiplied by its respective weight, and the suitable layer was produced by overlaying the raster layers.

The findings indicate that using the AHP model in the ArcMap (GIS) environment can identify optimal and suitable educational locations.Conclusion and Recommendations: The results of the analysis of effective indicators in evaluating the location of educational centers have shown that most educational centers in this area fall under compatible conditions (with a weight of 0.669) and semi-compatible conditions (with a weight of 0.243), while incompatible educational centers only account for a weight of 0.088. The combined analysis of AHP and GIS regarding the location of educational centers in District 4 of Ahvaz city has demonstrated that this area’s central and northern points are the most suitable locations for establishing new educational centers.

Innovation and Originality: 

This research aims to correctly locate educational centers to improve the quality of education for the first time in the studied area.

Urbanization is the most prevalent complication in developing countries. Therefore, city managers, as the top of the city leadership pyramid, have a heavy task to create coordination between the departments that manage the city. Urban management in developing countries faces many problems, including financial inadequacies and technical skills. Along with the rapid and rapid growth of urbanization in the world, especially in developing countries in the last two or three decades, the role of cities in the national economy of these countries has changed completely and is of vital importance.The aim of this study was to investigate and identify the challenges and crises of urban management in Ahvaz metropolis, which in terms of research purpose, except for applied research, is qualitative in terms of implementation process. Data were based on a survey method and a questionnaire technique and the information was collected by random sampling.Findings have shown that there is a difference between the challenges and crises of urban management in the city of Ahvaz and from the citizens' point of view, there are many challenges with different degrees of importance in this city. Citizens believe that management challenges and crises Ahwaz metropolitan cities in order of importance are: economic challenges; Cultural challenges; Environmental challenges; Social challenges; There are security challenges and urban service challenges. Conclusion According to the research findings, the need for urban management to information dashboard in the city and awareness of the current situation, information and financial resources, equipment tools, needs and problems of the city and the citizen, is felt more than ever. And takes steps to eliminate them by planning, organizing and monitoring.

With the development of urbanization, green areas was highly regarded and was recognized as an important symbol of urban ecosystem health. Parks and green spaces plays an important role in improving the quality of life of the people living in urban areas; But the uneven distribution of parks and negligence of the desired criteria for locating parks, makes the benefits and merits of the parks not to be realized as optimum. District No. 3of Ahwaz, due to uneven distribution and lack of observing the regualtions of the parks locating, is faced with the same problem; Thus, this study was conducted with the aim of locating new parks in District 3 of Ahwaz City. To achieve the above said goal, with a practical approach and Analytical and descriptive nature, the six indicators were used which were deriven from the studies and expert opinions that the required information were gathered and analyzed by studying literature, previous researches, development plans of Ahvaz. And by the Analytic Network Process and network analysis tools in Arc GIS software were analyzed. Calculations showed that11 neighborhood of district No.3 of Ahwaz has no park. By comparing the standard per capita of parks in neighborhoods and the detailed plan approved in 1997 (13.4 m2) it was founded that 76.78% of neighborhoods in terms of having Park are placed at deprived and underdeveloped condition. Review of the performance radius of the parks showed that 53 percent of parks are in a good condition in providing services to the objective residents and the remaining 47 percent are in unfavorable condition. The findings of locatioing of new parks was twenty places, which the priority of their establishment was determined by the application of Super Decisions software. The results indicated that the distribution of parks is very unbalanced in district No.3 of Ahwaz City and the population density is not regarded and the rinciples of park locating has not been observed And for overcoming such gap, construction of a new park is required. But the construction of new parks should be based on the existing standards in order that while providing higher performance ensures the quality of life and satisfaction of Citizens.
