Abstract
Sustainable development is an environmental concept appropriate to our era that nowadays in all of economic, social, environmental and physical-spatial aspects is considered and focused by everyone. In these times, global organizations that are working around the issues of sustainable development, emphasis on rural sustainable development, which seeks to improve rural living standards and welfare of the inhabitants of the villages, because at present time, the procedure of socio–economic variations accompanied by increasing migration of human groups is led to evacuation of villages. With attention to the importance of the subject and the increasing instability of the villages, present study was done for determining the effective factors on rural instability and measuring the intensity of this instability in Kaki District of Dashti Township. The research method is descriptive - analytical in which whole inhabited villages of Kaki District of Dashti Township were surveyed. In this regard, according to the number of households living in villages and using the Cochran formula, 255 questionnaires were calculated for questioning andthese questionnaires have been completed in the villages in proportion to the population of each village. In these questionnaires, 34 indicators related to the four dimensions of sustainable development (environmental, social, economic and physical-spatial) are considered. In order to determining instability intensity of the villages and their spatial analysis, is used AHP method in Expert Choice and ArcGIS software. Also SPSS software is used for statistical analysis. The results show that at the present time, all villages have various degrees of instability. In this regard, 65.8 percent of these villages have severe or very severe instability.

Abstract
Higher quality of services provided in the rural areas requires feedback, consulting with villagers, and their active participation in rural development process. Water services are one of the most basic services provided in rural areas. Accordingly, the present study seeks to evaluate the satisfaction level of rural residents with the quality of services provided by Rural Water and Wastewater Company. This study was conducted in a descriptive-analytical method, and the population was comprised of 132 households randomly selected from rural residents living in rural areas of Central District of Neyshabur County with an acceptable reliability score. Investigating the relationship between the five dimensions of the study and the individual characteristics indicates that there is a significant relationship between age, gender and education level and satisfaction with quality of the services in sample villages. At the same time, assessing the satisfaction with the quality of water services in sample villages indicates that the quality of water services in sample villages is at a satisfactory level. The analytical results of the confirmatory factor analysis of the research indicators showed the highest percentage of variance of the research dimensions belonged to 'empathy', with 30.91% and the least value of variance belongs to ‘tangible changes’ (21.28%). The spatial analysis of villagers' satisfaction with drinking water supply services in sample villages showed that the village of Sheikhlan with 103.10 Qi had the highest satisfaction level, and the village of Turani with 0.990 Qi had the least satisfaction with the quality of services..

Abstract
This paper aims to explain the inequality and imbalance in the developmental levels of 6 selected cities in North Khorasan. The paper seeks to answer these two questions as to whether the spatial and non-spatial indices in regional disparities have an effect on equality? And can we achieve a functional model based on the evaluation of indicators? In order to achieve the goal and the answer to the question, indicators have been selected based on the importance and effects of the factors in both natural and human aspects. The method of this research is descriptive-analytical in nature and in terms of access to the facts of the descriptive-survey type and in terms of The purpose is to apply. Data analysis was performed using SPSS software and multi-criteria and cellular analysis using the coefficient of variation formula. Thus, the coefficient (from one to another) was determined in each case, the influential elements and the prestigious countries of inequality. The results show that the city of Bojnourd with a coefficient of 90 channels in North Khorasan has been used for structural changes by providing data matrices and presenting maps (with the help of GIS), and the most change coefficient is related to the percentages of urban population percentages. Other results of the study indicate that according to the coefficient of variation and determination of z in the cities of North Khorasan province, Bojnourd city has the first rank in 6 indexes of 10 selected indexes and its z value is 8.57 and the clear distance with Shirvan is The title of the second city is with a z = -3.54. The final finding of this research is modeling in the structural-functional changes and changes in North Khorasan which was proposed at the end of the paper.

Abstract
Spatial Analysis of Crimes at Different Hours of the Day, the Days of the Week, Month, and Seasons is an Effective Way to Control and Prevent Urban Crime. These analyzes give city management and other city safety officials, including law enforcement officials, the possibility to take preventive measures to eliminate or mitigate the effects of these factors in the city. The purpose of this study was to investigate the spatial analysis of theft crimes on a daily, weekly, monthly and seasonal basis in the 12th metropolitan area of Tehran. The research method in this article is descriptive-analytic. The comprehensive statistical data included the statistical blocks of 1390 in the neighborhoods of the 12th district of Tehran and the crimes related to theft in 2010. The most important statistical tests used are the Center-Medium and Oval-standard deviation tests, and from among the clustering tests, the nearest neighbor index is used to identify massive cores. The results of this study indicate that 446 crimes related to theft, Ferdowsi and Lalehzar neighborhoods, and Sa'di Baharestani have the most crimes and minorities in Kosar and Mokhtari. The pattern of distribution of crimes in the 12th region is clustered and the most important crustal focal points are formed at the intervals of the Shemiran, Iran, Baharestan - Saadi, Ferdowsi -Laleh Zar, Arg Pamenar, Imamzadeh Yahya and the Cascade. The spatial analysis of stealing crimes also suggests that the direction and extent of theft is different at different times of the day, weekdays, and on a monthly basis.

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
The endogenous growth pattern reflects the importance of the quality of human capital and even the social system and governance in which culture is considered as the source of ideas for economic sectors. A review of the policies and priorities for the development of the new economy highlights the importance of creative city indicators in managing the challenges and cultural and economic diversity of current cities. The research method in this study is descriptive-analytical and it is applied in terms of purpose. . The method of data collection is mainly library and documentary by means of catch-up, housing statistical blocks of 2016 and detailed plan map of 2015. Combined methods of the factor analysis and spatial statistics in GIS are used for analysis. Most of Zanjan's neighborhoods lacked creative class attraction indices and spatial distribution of Zanjan's central and northern creative city indices was relatively favorable. Zanjan's neighborhood development policies have less attention to the interests and priorities of the creative class, and urban spaces other than the central and northern neighborhoods are not conducive to social interaction and creativity of residents, and urban residents, especially urban east and west, have become passive recipients of urban services and facilities.
