The present study aimed to identify and rank the factors affecting the selection of architecture and leveling of educational centers according to climate conditions using the ANP method. Library and field methods were used to collect data. Data collection tools were databases related to climatology in the Ahvaz metropolis. To weigh each factor, the opinions of experts and ANP were used. The factors were also ranked based on the weight of each factor. The results revealed that pollution prevention with a weight of 0.099, sunny hours with a weight of 0.099, and access with a relative weight of 0.096 had the highest weights among the obtained sub-indices. Thus, they were ranked first to third, respectively. Other sub-indicators were placed in other ranks based on the weights obtained.

Today, with the expansion of urbanization and the increase in the population of cities, urban poverty is one of the important problems that it seems necessary to fight. In the 21st century, one of the indicators of urban progress is the issue of low urban poverty (Lemanski and Marx, 2015). In order to analyze and evaluate the indicators of urban poverty in Rasht city in different blocks and to cluster social poverty in this city (very poor, poor, average, wealthy, very wealthy), to analyze social poverty and extract spatial hot spots from Arc software. Gis was used. And the extraction of different areas of the city was calculated from the R software and by the multi-indicator Prometheus decision-making method, where the weight of the indicators was obtained by the ANP method from the raw data of the statistical blocks of Rasht city in the census of 2015. The findings of the research showed that comparatively, the central parts of the city are covered by medium blocks, and in the outer and peripheral parts of the city center, two hot spot areas are observed, which contain very prosperous blocks. Cold spots are also clearly visible on the outer edge of the city and they cover very poor and poor blocks, and except for the hot and cold spots, the city is mostly in the form of mild spots and most of the blocks are in poor condition. They are placed in average social poverty. Also, based on the findings of the research, most of the deprived areas in terms of social poverty in Rasht city are located in the north-west and north-east parts of the city.

In order to evaluate the level of urban poverty in different blocks of Rasht city and to cluster poverty in this city (very poor, poor, average, prosperous, very prosperous), 17 indicators of urban poverty using Arc GIS software and hot spot analysis method The space of urban poverty was drawn according to their poverty components. The rate of urban poverty in different blocks of Rasht city was calculated using R statistical software and Prometheus multi-indicator decision-making method, where the weights of the indicators were calculated using the ANP method from the raw data of the statistical blocks of Rasht city obtained in the census of 2015. The findings of the research showed that the hot spots (prosperous and very prosperous) are mostly seen in the central core of the city. On the other hand, cold spots (poor, very, and poor) are mostly observed in the outskirts of the city in the east, west, and southwest of Rasht city. The border between these two regions of moderate spots is a dividing line and the border of urban poverty from poor to wealthy. The comparison of the components shows that educational poverty has followed and expanded from a uniform structure in this city. The noticeable difference in the dimensions of urban poverty is in the social component and the economic component, so that the pattern of distribution of social poverty and economic poverty are inverted, wherever the social poverty is more, the economic poverty is less in them. Also, a significant difference between educational poverty and social poverty can be seen in the northeastern region of Rasht, which is poor and very poor in terms of social poverty, and on the contrary, it is prosperous and very prosperous in terms of education.

In this research, the multidimensional poverty index approach was used to calculate the amount of urban poverty in different blocks based on the components related to economic poverty, social poverty, and educational poverty.

In the city of Rasht, the dimensions of the physical development of the city have more obvious consequences. With its social, economic, industrial, etc. attractions, Rasht city has been known as a population attraction pole in the region, and the demographic changes and the subsequent physical development of the city after land reform in the second Pahlavi period from 1956 until now confirm this. Due to the location of this city in a smooth and fertile plain, this development has generally been associated with the destruction of agricultural lands and the annexation of villages around the city. Considering the rapid changes in population and the physical growth of the city, the need for planned development and urban organization is felt more than before.The effective factors in increasing the number of immigrants to the city of Rasht can be divided into two main natural and human groups from the point of view of geography and urban planning: natural factors such as: special geographical situation and earthquakes that happened in the surrounding cities. Human factors such as: political, economic-social factors, as well as rural repulsive and urban attractive factors. The increase in population has caused the reduction of urban per capita, so that different indicators are completely unbalanced in the city.The spatial expansion of Rasht city has expanded in a spiral and within the void and has integrated many agricultural lands within its service limits. Among other things that have been affected by the population growth are the heavy pollution of the rivers located in the city, as well as the increase in the production of garbage, urban sewage, and the change in the use of agricultural land. The growth of the population and especially the arrival of immigrants in Rasht city has caused a kind of selective economic-social separation in the city. Among other things, we can mention the increase in the level of informal settlements in the outskirts of the city and the increase in the amount of social crimes in these areas.Although the expansion of the city in the form of a star causes the land to remain empty in the distance between its radii, but these lands provide better conditions for the development of green spaces, forestry and parks. In general, at some distances from this design, the big ring roads connect the radii to each other. There is no development around the main roads. The main roads connect to different areas of the city at the intersection with Shuaa. This form is the logical result of the expansion of concentrated cities that begin to expand along the roads outside the city. Star city development allows for a centralized and compact model with a center and pulls public transportation to the city center, so that the entire city and its people have access to the city center, which, among other things, The merits of the plan are counted. Also, the existence of green spaces that have access to rural spaces also provides an environment for walking, cycling, horse racing and sightseeing. The theoretical model of the development of Rasht city, a combination of three models of multi-core construction (with the main cores of the central market, Zarjoub, Motahari Street, Pirsara and Golsar), general construction of the city (establishment of service units based on the geographical conditions of the city) and sectoral construction (Nashi) It is from the creation of radial streets such as Imam Khomeini, Shariati, Lahijan, Saadi, Shahid Ansari, Biston and Lakani Street). Due to the construction of this city, it has a radial-ring construction, which is indicated by the communication lines and accesses.

Based on the research findings and the comparison of social poverty, economic poverty, educational poverty and urban poverty in Rasht, the distribution of poverty in Rasht follows a uniform structure and has expanded. The noticeable difference in the dimensions of urban poverty is in the social component and the economic component, so that the distribution pattern of social poverty and economic poverty are inverted, so that wherever social poverty is more, economic poverty is less in them. A clear example of this is Hafez Abad in the west of the city. It is Rasht. Also, there is a significant difference between educational poverty and social poverty in the northeast region of Rasht, the rural neighborhood of Imam Reza, which is poor and very poor in terms of social poverty, but prosperous and very prosperous in terms of education. In terms of similarity, a significant similarity between the social dimension with the educational dimension and the economic dimension with the multidimensional poverty of Rasht city can be seen in most parts.

Natural hazards can be considered as one of the most important threats to humankind and nature that can occur anywhere in the world. Natural hazards are one of the main obstacles to sustainable development in different countries and one of the important indicators of the development of world countries is their readiness to deal with natural hazards. Therefore, it is important to pay attention to it and appropriate measures should be taken to reduce the vulnerability of human settlements. Nowadays with increasing population growth, population dynamics and the large number of people exposed to various types of disasters, the need to identify environmental potential hazards and identification of hazardous areas are felt more and more. Meantime, some people may not be aware of potential hazards of their place of residence. So by identifying and evaluating potential hazards and their Risks before the occurrence, we can significantly reduce the severity of the damages and contribute to sustainable regional development. The negative effects of natural disasters can be minimized by the availability of comprehensive and useful information from different areas and Multihazard mapping is one of the most effective tools in this regard.
According to the above mentioned, in this study, the spatial analysis of potential hazards in Silvana district in Urmia County has been studied. This study area due to specific geographic conditions such as position, complexity of topographic and ecological structures, in general, the existence of environmental factors for hazards has been selected as the study area. There have been a number of hazards in the past and assessing of this area is necessary, because of the lack of previous studies. For this purpose, by reviewing various reports and doing field observations, three hazards including Flood, Landslide, and Earthquake are identified as potential hazards of the study area.
For assessing hazards, 12 factors in 6 clusters such as Slope, Aspect (Topographic factors), Lithology, Soil type, Distance to Faults (Geological factors) Precipitation (Climatological factors), River Network Density, Groundwater Resources (Hydrological factors), Land use, Distance to Roads (Human factors), Observed Landslide Density and Seismicity (Historical factors) as the research factors has been selected. For weighting factors, Analytic Network Process (ANP) Method in Super Decisions 2.6.0 software environment has been used. The results of the analysis show that Slope (0.201), Precipitation (0.161), Lithology (0.112), Distance to Faults (0.106), Land use (0.096), Rivers (0.078), Seismicity (0.06), Soil Type (0.055), Landslide Density (0.047), Aspect (0.033), Groundwater (0.03) and Distance to Roads (0.016), Respectively have maximum to minimum relative weight. Then, weighted maps are standardized with using FUZZY functions. For this purpose, Fuzzy membership functions such as Linear, Large and Small has been selected based on each factor. For some factors such as Slope, Aspect, Lithology, Soil type, Rivers density, Land use, Seismicity and Landslide density, Fuzzy linear function has been used. For some others such as Groundwater and Precipitation, Fuzzy large function has been used and for distance to Faults and distance to Roads, Fuzzy small function has been used. Finally, weighted maps were overlay in ArcGIS 10.4.1 environment with Fuzzy Gamma 0.9 operator and potential hazards zoning maps is obtained.
Final results indicate that major parts in the Northwest, West and South of the study area located in high risk zones and 59 percent of the total area exposed to high risk. Based on hazard zoning maps, 44 percent of the area exposed to Flooding, 48 percent exposed to Landslide and 44 percent exposed to Earthquake. Also, 61 percent of the population or 37394 people exposed to one hazard, 7 percent or 3817 people exposed to two hazard and 8 percent or 4914 people exposed to three hazard. According to surveys, only 21 percent of the study area is considered as a low risk area but that does not mean that environmental hazards will never happen in these areas. In general, and based on results, it is concluded that Silvana district has a high potential for environmental hazards. Final results of the research show that potential hazards identifying and preparation of hazard zoning maps can be very useful in reducing damages and achieving sustainable regional development. Therefore, considering the ability of hazard zoning maps to identify areas exposed to risk and assess the type of potential hazards, These analyzes should be considered as one of the most appropriate and useful tools in different stages of crisis management that can be the solution to many problems in preventing and responding to natural disasters and therefore, it is recommended that they be used in the crisis management process.

The theory of Creative city is implicated that the cities have potentials and facilities, can cause to juice up the economic and social inflorescence of cities, if it’s applied exactly. Because this theory such as almost theories in urban design field is obtained from western countries, then we don’t expect to achieve the best results while we use the indexes which provided for west cities. We tried in this research to ranking the sextet district of Zanjan city with use the creative cities that adapt with Islamic and Iranian culture and civilization. For achieve to this goal, in primordium we done priority processing the indexes by ANP method. The results of research in this stage show that human and social (0.315), economical (0.133) and educational (0.110) indexes catch a highest rang. Then we ranking the sextet district of Zanjan city with use the TOPSIS method. The results of this research show that 3 and 4 districts have highest rank and 6 and 2 districts lies in middle rank and 5 and 1 districts lies in lowest rank. The study manner of this research is descriptive and analytical and the methodology used in this study is librarian studies and field observations.

Main question (or main goal): Assessing the level of educational poverty in different blocks of Ardabil city and clustering educational poverty in this city (very poor, poor, average, prosperous, very prosperous). In the 21st century, one of the indicators of urban development is the issue of low urban poverty. One of the components of urban poverty is educational poverty. This study showed that educational poverty has a cluster distribution and spatial autocorrelation in the Ardabil. However, the imbalance of spatial space between neighborhoods in this component has caused the disruption of spatial order and the growth of urban spiral in some parts of Ardabil and the marginalization of many other areas of the city. Relatively the southern and southwestern part of the city It includes very prosperous and prosperous blocks and poor and very poor blocks in terms of educational poverty are seen in the northwest and southeast. Hot spots include new settlements that were built after 1370 in Ardabil. In contrast, cold spots are more common on the outskirts of Ardabil and in informal settlements resulting from migration from other cities. The boundary between these two areas i.e., the central areas and in the whole basic texture of the city; includes: moderate spots and the border of educational poverty. Raw data of blocks were obtained based on the 1395 census, the rate of educational poverty was weighed using R software and ANP method and Arc GIS software was used to analyze hot spots in the spatial range of urban poverty according to their educational poverty.

Catalyst projects are one of the most recent approaches to urban regeneration literature in the world and in Iran. . In this research, using descriptive-analytical methodو attempting to use the scientific and practical research in selected cities of the world (England, the Netherlands and Iran) and in order to achieve the purpose of the article, the success factors of the implementation of the mentioned projects are expressed. for achiving this goal, five examples of implementation of development Catalyst project from selected countries were selected. In process using the ANP method in Super decision software, a pairwise comparison of the criteria, sub-criteria and options was performed and, finally, after obtaining the weights associated with them, It is concluded that at the level of criteria, the most important factors in the success of the projects are reliance on social and economic criteria. But in more detail, such as environmental improvement(environmental criteria), public space (social criteria), economic actors, branding and improvement of housing (economic criteria), public services, attention to context and fabric and, ultimately, land use (physical criteria) One of the most important factors is the optimal implementation in Catalyst project.
