The purpose of this study is to investigate the impact of citizens on the quality of life in urban areas that Karmandan and Islamabad neighborhoods of Zanjan city were selected as a case study. This research was applied based on a purpose and descriptive-analytical based on a nature which has been performed by using SPSS software and descriptive tests such as mean, Pearson and ANOVA. The results of research showed that the mean of social capital indicators were different in Karmandan and Islamabad neighborhoods, but in both neighborhoods the mean of neighborhood participation and leisure time indicators were lower than the average. Also, the quality of the physical environment indicators in the Karmandan neighborhood was at a high level, while the mean of housing facilities and leisure amenities were lower than the average mean. In Islamabad neighborhood, traffic safety, waste disposal and access to public services indicators were above average and also it was at a lower level in terms of these indicators relative to the neighborhood of Karmandan. Both neighborhoods have had the highest impact on housewives and retirees of occupational groups. There is a significant difference between the impact of employment and the quality of the physical environment in the Karmandan neighborhood. Whereas in Islamabad, there is no significant difference between women's employment and the quality of the physical environment. As a result, the employment of different groups of women has not affected the quality of its physical environment.

Crime as the most important social problems in many cities in the world that has a negative impact on the lives of people with mental, physical and financial shares. This article aims to inefficient spatial analysis of crime in the context of the neighborhood martyr Tehran Harandi District 12 is performed. The research method in this study is an analysis and matching to identify and understand patterns of crime in the neighborhood Harandi statistics and graphics based on GIS is used, the information needed for the amount and type of crime as a library of Tehran Police is derived. The findings showed that crime hotspots in the neighborhood Harandi are randomly distributed. On the other hand high levels of exhaustion, high permeability, and the presence of vacant lots and abandoned as well as the lack of some required applications of citizens, to increase geographical distribution and type of crime rate and the formation of spatial patterns of crime have been effective. It seems that with the improvement and renovation of old ones and modifying the physical and physical spaces, widening the passages under 6 meters and make way for streets impasse, locate police centers and recreational spaces and leisure healthy increase in official monitoring in this area can be possible the vulnerability of these communities and reduce crime.

In this research, it was attempted to evaluate the Tourism Carrying Capacity in the Khaleej-Fars park of Foulad Shahr as one of the urban parks. The main purpose of this research is to compare the different types of tourist carrying capacity using the IUCN method and identify its weaknesses and strengths as a way to improve its management. Data was collected through field surveys, questionnaires, climatic statistics of Zarrin-Shahr Weather Station and experts' opinion. The results of using the IUCN guidelines showed that the Khaleej-Fars park with an area of 93000 square meters with a physical carrying capacity of 325872 people, has a real carrying capacity of 78183 people and an effective carrying capacity of 39091 people per year. Also, the service capacity of the park was more than the management carrying capacity. Therefore, before designing and implementing infrastructure and facilities in urban parks, it is recommended to estimate the effective carrying capacity firstly, and then designing and application of facilities in accordance with principles and in proportion to the capacity of the road.

Urban neighborhoods have a special place in the minds of the citizens of the region due to individual and collective memories. Hence, the concept of habitation and its formation in the relationship between human and place is closely related to the fulfillment of human needs and behaviors. In this regard, identity is an essential part of the sense of feeling and belonging that need to be considered in the design of residential environments. The general purpose of this study is to identify the elements that affect the sense of belonging to the place in order to approach the identity of residential units in urban neighborhoods. This study was carried out in the old and valuable neighborhood of Saghrysazan Rasht as a case study. The method of this research is descriptive-analytical based on logical reasoning as well as using a mixed strategy (qualitative-quantitative).In order to study indigenous houses and buildings, a questionnaire for measuring indicators was prepared and adjusted, after that it was distributed among 47 residents of this old texture. Then, the collected data were analyzed by SPSS software. The evaluation of the results showed there is a significant dependence among residents of old housing units over new apartments in the Saghrysazan neighborhood. The reasons for this issue included economic, cultural and infrastructure problems in the old texture, uniformity environment and high-rise building, decreasing in indigenous identity, lack of sense of collective life, Immigration, Lack of attachment to the environment, change the attitude of people to life.

y in Ardabil province analyzed the precipitation data of 30 years from 1987 to 2016. Most of the precipitation occurred on 09/12/1991.Synoptic atmospheric maps of this date at a level of 500 Millibars were prepared by sea level elevation maps, geopotential heights, wind speed and direction, humidity, temperature, perceptible water on ground level and blocking (omega), using satellite images from NCEP/NCAR databases which Affiliating to the National Oceanographic Organization of the United States. The research method is a circular environmental approach. The results showed that in addition to the ground and climate conditions that have been effective in causing heavy rainfall during this history, the internal situation with the external pattern, such as the seas around and adjacent to Iran like the Black Sea and the Mediterranean has been affected. The monthly precipitation of Khalkhal station as a region that is more prevalent in the south of Ardebil province and southwest of the Caspian Sea in the three months of the spring season is more than February (1321/8 mm), March (1716.7 mm) and April (1448 mm). The most natural atmospheric hazards affected by heavy rainfall and flood damage in Khalkhal, inland, village, river and agricultural damages occurred during these months.

In recent decades, in line with the rapid growth of urbanization, the quality of life, as a substitute for material well-being, has become the main social goal of different countries. In this regard, the purpose of this article is to analyze and evaluate the components of quality of life in crime centers in district 12 of Tehran municipality. The method of this study is a descriptive-analytical approach and the data collection is based on library studies (documents) and field observations. At first, the crime centers were identified by using ArcGIS software through extensions of kernel density, and then 400 questionnaires were randomly filled out at the crime centers. In order to analyze the studied variables, SPSS software and one sample t-test and Pearson correlation test were used. The results of one sample t-test showed that the average mean of residents' satisfaction in socio-cultural dimensions 2.63, economic1.98, security 2.56, access to daily shopping centers 2.86, access to recreational centers 2.65, access to training centers 2.43, environmental 2.33, urban infrastructures 2.83, housing 2.37, transport and traffic 2.58 and urban governance 24.24 were at a lower level. Also, Pearson correlation was used to examine the correlation coefficients of dimensions of quality of life with total quality of urban life. The test indicated that the eleven dimensions of quality of life have a direct and significant relationship with the total quality of urban life, meaning that each dimension of quality of life increases with the amount of total quality of urban life. Finally, the results mentioned that the desirability of urban quality of life in the crime center of district 12 in Tehran was very poor due to all dimensions and components, so this part of Tehran has a low quality of life.

Over the past decades, the declining process of city centers has intensified due to the over relying on modern urbanism based on movement of cars and neglecting to organize pavements what is contrary to the sustainability of the city. The increasing trend towards sustainable urban development has caused urban planners to put forward the theory of new urbanism to save urban centers and the authorities to consider plans in order to pay attention to pedestrians which is one of the dimensions of new urbanism. The present paper also seeks to explore the walkability of the existing streets in the historical texture. In that direction at first, the view of pedestrians, in the form of distribution of 400 questionnaires, has been evaluated in terms of the quality of seven main indicators of walkability, including accessibility, safety, security, furniture, attractiveness, transportation and social activities in the study area. Accordingly, streets in the historical texture has been prioritized using the second type of Promethee technique. Based on a result of this technique, Beheshti, Khajeh Nasir South, Oohadi, Imam Khomeini and Daneshareh streets and so on have the highest level of walkability respectively. The results of this study showed that only 20% of the passages in the historical texture have walkability features.

The purpose of this study was to investigate the effects of the establishing of nature school on urban livability in Pardisan Park in Tehran. The research was descriptive-analytical that its analysis was performed by using the Delphi technique. The results of research showed that environmental education as a school of nature has a direct and indirect impact on the components of sustainable urban livability. Also, the amount of impact the whole dimension of nature schools for environmental, economic and social indicators was 0.538, 0.521 and 0.429, respectively. Therefore, the establishing and development of nature schools will improve the urban livability.In addition to this amount, the direct effect, which indicates the impact of the indicator on the livability without interfering with other indicators, is slightly different from the overall effect which indicating the direct and great impact of indicators on the livability.

Thunderstorms rainfalls are a kind of unstable storms that are caused by an extremely strong abnormal state of atmospheric displacement and are one of the most important climatic phenomena in the northwest of the country.The aim of this study was to determine the spatial distribution of thunderstorms rainfalls in Ardabil province by using satellite images and Estimation of perceptible water. In this study, synoptic stations data, satellite imagery and MODIS bands 17 and 18 for Estimation of perceptible water were used. Images of thunderstorms rainfalls on 05.10.2010 and 18.06.2012 in ENVI4.4 software was processed and then they were interpolated in ArcGIS. Also, the results of interpolated field data revealed that the highest thunderstorms rainfalls are at Khalkhal station and lowest occurs in Meshkinshar station. In addition, thunderstorms rainfalls in the province in the spring and early summer lightning occurs. The results of the analysis of ground data and satellite imagery indicated this fact that the thunderstorms rainfalls derived from satellite imagery is far more accurate than data that obtained from the harvest of the earth. Also, maps of thunderstorms rainfalls can be extracted quickly and accurately, as well as using in the prediction of atmospheric hazards and optimal water resources planning in Ardabil province.
