Abstract[1]
The basis of the emergence of new theoretical approaches in urban construction, design, and planning, such as green cities, healthy cities and ecological cities, is to pay attention to the urban environment and to pay more attention to the planning of green spaces use in the design and construction of densely populated cities in terms of physical and demographic aspects. Therefore, the existence of such use is vital and essential in today's cities. Therefore, in this study, with descriptive-analytical methodology, the aim of the study is to evaluate and analyze the optimal locations for the establishment of urban green spaces in Mahshahr city. In this regard, according to available data, the indices determining the goal of the research are 11 major urban users in the city of Mahshahr under the name of commercial, cultural, medical, educational, green space, industrial, religious, administrative, communication, sports, and tourist-historical places that have been used to analyze the optimal location of green spaces. To analyze the data, the indices of research (the classified 11 uses) were introduced into the fuzzy using Arc GIS 10 first, and then,were analyzed using the Fuzzy Gama (Fuzzy Gama) operator.The results of the study show that the threshold limit test of 0.7, 0.8 and 0.9 in the fuzzy gamma operator with regard to the existing conditions of applications, the fuzzy gamma with a threshold of 0.9 has analyzed the spatial location of urban green space in Mahshahr city better than the rest of the threshold values tested, taking into account the importance and balance In the decreasing and increasing trends of applications.Also, according to the results of this operator, the central parts of the city in both the western and eastern parts of the city are the most appropriate places for the establishment and location of urban green space.

To date, a number of plans have been implemented to reduce air pollution in the city of Tehran.But the problem is that, along with other shortcomings,these planshave often been a passive and temporaryreaction to the increase of air pollution with adherence to crisis management rather than risk management, and no decision-making support system has been used in management decisions based on these plans.Therefore, due to the importance of the subject, this research was carried out by an analytical-applied method using hourly data, carbon monoxide density of 12 stations from a collection of air pollution measurement stations belonging to the air quality company, as well as meteorological dataof wind speed, wind direction and the temperature at the Mehrabad station, all related to the year 1389, and the number of the cars on the highways and streets of city of Tehran with the aim of predicting the temporal-spatial air pollution caused by the urban transport of Tehran Metropolis in line with the application of the spatial decision- making of the air quality management and with the ultimate goal of optimal management of urban transport of Tehran Metropolis. In this regard, since the ultimate goal of the present study is to use its results in controlling the optimal urban transportation as an important source of air pollutants, the LUR method was used to measure carbon monoxide index in the transportationof Tehran metropolis along with other pollutants. An artificial neural network was then used to predict the time of the possible occurrence of air pollution with emphasis on using risk management, and then, based on time predictions resulted from the artificial neural network, the regions with high possibility of air pollution occurrence were identified using the Kriging index.According to the findings of this research,the results were appropriate, so that this model could be used in the air quality management support system to reach the ultimate goal of optimal urban transport management in Tehran Metropolis.

One of the characteristics of the tribal system and communities with tribal structures is usually kinshipism (Khishavandgerayi). Heterogeneity in tribalism and geographical variations usually reduces the national cohesion of the state. For this reason, the present research was carried out with the aim of assessing the role of tribalism in feeling the social security of the citizens in the city of Izeh.The research methodology is descriptive-analytical with a practical-theoretical approach. The required information was collectedthrough a library and field procedure(questionnaires and interviews). The statistical population included all the citizens above 15 in the city of Izeh and a sample of 348 people was obtained using the Cochran formula. In the next step, the collected data were analyzed by SPSS software using Pearson and Spearman tests and the results were presented in tables. GIS software has been used to edit maps. The results of the study show that52.6 % of the respondents were women and 45.1 % were men. 36.5 % were single and 50.9 % were married. 55.2 % of the respondents considered the tribal environment of the city as the cause of feeling insecure, and 43% considered the tribal clashes to be the cause of such feeling. 21.5% have left their home because of tribal conflicts. 19 % do not commute in the city during the conflict among the tribes. One of the other results of this study is that, there is a direct and significant relationship between education, the tribalism environment of the city and the citizens’ feelings of insecurity, but there is a reverse and significant relationship between prejudice in favor of their own tribe and feeling social insecurity.
