Abstract
Interactions and sometimes contradictions in economic and cultural priorities which happen due to social transformations, changes in paradigms and changes in economic – political systems led to changes in urban regeneration concept. The role of culture in urban regeneration had significant changes comparing to other factors; and the cultural focuses became the main approach in urban regeneration in recent decades. The quality of built environment and level of residents’ satisfaction plays an important role in regeneration policies of target areas as well. This study investigates the impact of environment quality variables (environmental, physical, economic and social) on level of residents’ satisfaction in cultural neighborhoods of Kerman, with the goal of improving the regeneration process.The method of this research is applied-developmental in terms of the aim, and descriptive and causal comparative in terms of the nature. This study uses questionnaire as a tool for collecting data. The study sample size is 513 and the data were analyzed by SPSS and AMOS softwares. The results demonstrate a significant direct relationship between economic and physical variables as well as social variables and consequently the same relationship between economic and the sense of satisfaction. The results also indicate a significant inverse relationship between environmental variables, which are effective on sense of satisfaction, and economic variables. The results of structural equation modeling (SEM) show that improvement in the condition of economic, physical and environmental variables, will improve condition of social variables and the sense of satisfaction in the studied neighborhoods. Furthermore, analysis showed that economic variables have more effect on social variables and eventually on the sense of satisfaction as compared to physical and environmental variables. Therefore, the negative effects of each four aforementioned factors could be decreased in the studied neighborhood through planning and application of culture-led regeneration policies. Accordingly the increase in the sense of satisfaction would improve the revitalization and sustainability in these neighborhoods.

Abstract
One of the most important and urgent issues of urban planning is the equitable distribution of facilities, services and accessibility of citizens at the urban level. Economic and commercial centers, including banks and financial institutions, are one of the most important economic sectors of cities and can be sustained. Social, economic, physical, and environmental impacts of neighborhoods. The purpose of this study was to investigate the extent of citizenschr('39') access to commercial land use in Ardebil neighborhoods. Therefore, the present study is applied in terms of purpose and descriptive-analytical in nature. The statistical population of the study is 44 localities of Ardabil city. Spatial statistics models, Hot Spot Analysis, and GIS software were used for data analysis. Finally, regression function in Idrisi Selva software was used to analyze the correlation between commercial user and population as well as to determine the relationship and correlation of this user with other service users. The results show that in Ardabil neighborhoods there is inequality in terms of overall business use. As a result, the neighborhoods have high commercial use weights and high concentrations of hot spots in optimum condition, including areas 3 and 5 from zone 2, zone 7 from zone 1 and zone 6 from zone 3. Also, commercial low weight blocks and low concentrations of hot spots, which include areas 8 and 11 from zone 2, area 11 from zone 3, are lower in urban sustainability. Finally, based on the results of the research, some suggestions have been made.

Abstract
In this study, in order to study the base temperature (minimum temperature for plant growth) at the degree of growth day (GDD), which is one of the important parameters in calculating the degree of growth day, first, the data required for the 2009-2017 statistical period of wheat production at the station Sararood was taken from the station. Then, after sorting and separating growth different stages, using four methods of calculating the base temperature (1 - minimum standard deviation SDgdd day, 2 - minimum standard deviation SDAY days, 3 - regression coefficient per day CRday, 4 - CV coefficient of variation) was the most suitable method for calculating the base temperature of growth in different stages of planting to wheat harvesting. The results showed that the most suitable method is the minimum standard deviation in GDD, which The base temperature was obtained from germination to full reach for different growth stages, 5/8, 0/38, 1/8, 2/6, 0/63, 2, 3/7, 9/7, 8/6, 11 degrees Celsius. By comparing different methods of calculating GDD, the most appropriate of method was the general method of calculating the degree of growth day due to the most of similarity to the station data. The degree of growth day in different stages was calculated based on their base temperature and the results showed that the calculation of the base temperature at each stage of the growth of the wheat was very accurate for GDD calculation and a precise estimate of GDD was obtained.

Abstract
In this study, the actions and interactions between the city and the border were studied and explained. This research is applied in terms of purpose and in terms of descriptive-analytical method in library and field method. Data were collected through questionnaires and interviews. The statistical population consists of one percent of the population of border towns of Zahedan, Mirjaveh, Dost Mohammad, Khash and Saravan(N=8092). Using Cochran formula, 367 people were selected as the sample. Data were analyzed using Structured Analytical Model (SOWT-ANP). Findings and results showed.the most important effective factor on city-boundary relations is social factors with a mean of 3.55 and among weaknesses, Most affected were social weaknesses with a mean of 3.63 and among the opportunities examined, economic and managerial factors with a mean of 3.53 and Finally, they have the most impact on all types of threats, injuries and social threats with an average of 3.75. Also, the use of the method(F.ANP)in this study showed that the highest weight related to the threat factor was "management", which gained 7.9% of the final weight and took the first place. "Establishing economic, political and environmental security to deal with crises, attacks and ... (ST2)" is the most desirable strategy of deciding on the issue of zero value. And the strategy of "non-cooperation and interruption of cross-border relations with neighbors (WT1)" has been identified by experts as the worst strategy in this regard. Therefore, it can be said that among the factors (SWOT) "threats and challenges" in security and management dimensions is the most influential factor And the real gap between the "opportunities" is the key to improving the relationships between cities and territories. Also, from the standpoint of sustainable development management (institutional and structural) factors with the highest degree of importance and social, economic and environmental factors are ranked next.

Abstract
This study examines the principles and criteria that lead to the adoption of a city - a case study: Sahebgharraniyeh Tehran district - is underway. The NLAS method has been used as the main research method and indicator in this research. In this research, we tried to evaluate the methodology of the NLAS method in Sahebgharriyeh neighborhood using the method of analysis of the hierarchical method of analysis of the NLAS method and to analyze the status of living in Sahebgharrani neighborhood based on the received responses and their analysis. Detailed analyzes based on factor analysis and hierarchical analysis method show that Sahebqaranieh's habitat status is based on three indicators of facilities and services, local economy dynamics and visual landscape situation and environmental pollution and its related components. After summing up Related items and calculation of general indices indicate that the local economy's dynamics indices with a mean of 0.96 and T-value of 968 / resulted in decreasing the viability of Sahebqaraniye neighborhood. But with 95 percent confidence, Sahebgharriyeh neighborhood can be considered as individual and social security indexes, identity and sense of place belonging, facilities and services needed, and the status of the visual landscape and the environmental pollution of the habitat.

Abstract
According to statistics, about 300,000 disabled people live in Iran. There are about 25,738 disabled people in Ardabil province. This calls for attention to macro-planning for the disabled. This planning involves cognitive and spatial analysis of the status of the disabled people in different parts of the country. The purpose of this study was to analyze more precisely the situation of the spatial dispersion of the disabled and their relationship with different regions of the cities of Ardabil to address further the problems of accessing urban services and creating better living conditions for people with disabilities. In the present study, indicators such as age, gender, the status of residence, type and severity of disability, marital status, education and employment were analyzed using spatial statistics analysis. Also, the geographically weighted regression (GWR) model has been used to measure the relationship between the extent of development and disability. Findings of the research show that there is no relationship between the extent of development and disability in Ardabil province. The number of disabled males is higher than that of the disabled females in all cities. Disabled people in Ardabil province are young and 91.55% of them are illiterate and close to 96.74% of them are facing unemployment problems. In almost all cities of Ardabil province (73.98), there are severe to very severe disabilities and there is no specific order among different cities in the province of Ardabil regarding the type of disability, and various disabilities have been dispersed in the province.

Abstract
Air pollution is one of the major problems in large cities, which can be harmful to human health and the environment. Isfahan is one of the most polluted cities in Iran.
Its geographic location and low wind speed, industrial activities, transportation, agriculture, and other human activities have created critical air pollution conditions for the city. Nitrogen dioxide is an important pollutant of air pollution, which is monitored using ground stations and satellite measurements. In this paper, daily data of nitrogen dioxide from Ozone Monitoring Instrument (OMI) satellite sensor, wind and surface temperature of Isfahan Meteorological Station data were used between October 2004 and May 2016. The average amount of nitrogen dioxide in the measured range is .The highest amount of nitrogen dioxide ( ) was observed in December and the lowest ( ) was observed in July. The standard deviation of the winter season ( ) is higher than the summer season ( ). The correlation coefficient of nitrogen dioxide with wind and temperature was -0.41 and -0.54, respectively, which indicates the higher importance of temperature in nitrogen dioxide changes. After the formation of the time series, the average monthly nitrogen dioxide content was determined using spectral analysis of least squares of statistically meaningful peaks corresponding periods. These statistically meaningful peaks corresponding periods have been eliminated from the mean monthly nitrogen dioxide time series, and with the linear fit on the residual time series, the trend has been calculated. The nitrogen dioxide trend for Isfahan is per year with 95% confidence.

Abstract
In relation to the housing of the disadvantaged, the possibility of access to a suitable housing for every Iranian household in accordance with the household's needs in such a way that the housing concern does not exceed other areas of the household's life and stable and safe access to the household's housing is also guaranteed, showing the ideal vision of the housing sector in documentary studies, is related to disadvantaged groups. The purpose of this study is to achieve the set of strategies and the general form of realistic and effective programs in the field of housing support for the deprived and low-income groups, which, while determining the limits and type of government intervention in relation to housing and different economic groups, will make the target groups enjoy support programs faster. This study is based on the combined model of SWOT strategic analysis and QSPM strategic planning model and examines the findings of studies and the results of interviews with experts in the field of geography and urban planning. SWOT analysis showed that 1- Ignoring the lack of simultaneous use of the process of management and operation of low-income housing based on the participation of local social institutions and non-governmental organizations 2- Lack of necessary knowledge or disregard for the diversity of needs of the deprived and disregard for Special Characteristics of Target Groups 3. The imbalance between the benefits of different individuals in different groups in relation to support programs has led to the inefficiency of the policies of the deprived and the enjoyment of supportive housing for this group. "Empowerment programs" and "Attracting participation by exploiting local capacity and internal capacities by developing and diversifying empowerment", along with a general balancing policy to increase capacity in non-governmental sectors based on household participation. Faster households have support programs Provides housing and participation of all stakeholders in planning.
Keywords: development programs, government policies, housing for the deprived, SWOT analysis, QSPM model.

Abstract
Relative humidity is considered to be one of the most important climatic parameters and atmospheric phenomena. The purpose of the present study is to evaluate the regional algorithms for estimating relative humidity using remote sensing data in Hormozgan province. To this end, MOD05 and MOD07 products were employed to estimate total perceptible water, air temperature, and sea-level pressure Additionally, MOD35 was used for cloud verification, , resulting in the identification of 2190 cloudless images with 95% confidence level for analysis. radiosound data of Bandar Abbas ststion and synoptic stations Covering entire Hormozgan Province. were used to evaluate the results. The findings demonstrated high accuracy of the algorithms and experimental model, with acceptable R² and RMSE values between Modis product and ground data. These results align well with ground station measurements. The province's climate was determined to be semi-desert with a long warm season and a short cool period. Further analysis revealed a strong correlation between sea-level pressure and total perceptible water (TPW) with the region's topography. Maximum TPW and sea-level pressure values were recorded in coastal lowlands, while minimum values occurred in the highlands. Based on zoning maps, Hormozgan province can be divided into four regions based on relative humidity: from very dry conditions with less than 20% relative humidity in the highlands to humid areas with over 65% relative humidity along the coast.
