From childhood, human destiny has been intertwined with the environment and the surrounding space. Many educators believe that the personality of every human being is formed in the first 6 years of his life. On the other hand, the expansion of vertical constructions and the use of minimal space to create houses today do not give the opportunity to build yards and safe alleys for children's physical activities (such as running, playing, exercising, etc.). It is in this context that the role of public green space in the city for adults, especially children, becomes more prominent. Therefore, by examining the needs and problems that children face in urban environments, urban space designers can plan and design appropriate to provide favorable conditions for the physical, mental, emotional and social development of children and the flourishing of their talents and interests. Security and be actively present. However, the problem of lack of green space and its inappropriate distribution can be seen in many cities in Iran. One of the main reasons for this is the lack of water supply and dry air. The city of Semnan, as one of the desert cities with special climatic conditions, needs a favorable urban green space. In the present study, which is written in an applied type and based on a research-analytical method, data collection has been done in the form of documents (library) and field. A questionnaire was prepared to examine the research indicators and distributed among different sections of society. Then, using GIS and analysis, the significance coefficient was assigned to each of the indicators. Finally, according to the research formula of the study proposed by Mr. Kambiz Bahram Soltani, the proposed per capita amount for the use of green space in the city of Semnan due to unfavorable climatic conditions, 28 square meters was proposed. The result of the research shows that the city of Semnan, considering the climatic conditions, is far from the appropriate per capita research proposal. Finally, solutions to improve green space are suggested.

The present study has analyzed the spatiality of sports venues and evaluated the access to sports centers according to the pattern of their spatial distribution in the level of communication networks in Khorasan Razavi province. This research is of applied type and descriptive-analytical method. After determining the per capita sports uses in the province, using the Williamson model, the per capita distribution of these centers in the regions was measured according to population density. In the second part, using the Moran model, the spatial distribution pattern of sports uses (outdoor, indoor and total sports uses) was measured according to the area of these uses. The results showed that the per capita sports facilities in the province is equal to 0.34 square meters, which is less than the minimum per capita set for Iran. On the other hand, the total per capita sports space per household is about 1.05 square meters. also; The per capita outdoor sports space is more than the per capita indoor space (0.92 vs. 0.13 square meters per person). Meanwhile, Zone 1, which is in the northeast of the province, has a greater distribution of sports spaces and places, which, of course, has a greater distribution in terms of population. However, with increasing population density, the per capita total sports space (outdoor and indoor) increases with the slope of the line R2 = 0.5985. Also, according to the results of the nearest neighbor average model, it was found that the spatial pattern of distribution of sports centers in Khorasan Razavi province is 99% random. Therefore; solving these problems requires planning and management in the field of locating and organizing sports spaces.

The amount of Total Organic Carbon (TOC) is one of the most important parameter in evaluating hydrocarbon source rocks. Therefore, it is necessary to estimate of source rock by a method. There are several methods for estimating the of source rocks. One of the earliest methods is the traditional method, which is very expensive and time consuming, so researchers are looking for more efficient methods. Given the high potential of remote sensing and spectral VIR spectra, the VNIR makes it possible to estimate the characteristics of the origin rock at a lower cost basis. Different quantitative and qualitative methods are used to establish a relationship between the concentration of rock elements and the spectrum obtained from remote sensing data. In this study, we tried to estimate the total organic carbon content of the total origin rock using the OLI Landsat 8 image sensor and using the MLP artificial neural network model. For this purpose, the band of 5 spectral ranges (0.845-0.8585) with Pearson correlation coefficient of 0.62 was chosen for the neural network. An artificial neural network with neurons in the secret layer with R2 = 0.79 and RMSE = 0.0008 were selected to generate a total organic carbon map.

The limitation and scarcity of groundwater resources in Darab Fars plain has caused this plain to be in a critical situation and in the forbidden group. With proper management, the capacity of available surface and groundwater resources can be well identified and studied to make a comprehensive plan for their proper use. The use of GIS along with observational data leads to easy and systematic estimation of groundwater recharge areas. The purpose of this study is to identify the potential of groundwater resources using AHP model and fuzzy functions in GIS environment. To assess the potential of groundwater resources, 10 geological criteria, fault density, altitude, slope, land use, soil, geomorphology, precipitation, drainage density and distance from rivers were studied and analyzed. The layers were prepared in a GIS environment and then the potential of groundwater resources was modeled using fuzzy logic functions. The results showed that the use of 0.98 gamma showed more favorable results than other numbers. Areas with high groundwater potential were determined with high accuracy. To validate the model, exploitation wells in the region have been used. About 63.62 percent of this type of wells are located in areas with good and very good potential. Areas with good and very good potential correspond to the terrace reserves, alluviums and sediments of the fourth period and have a low slope (0-5 degrees). About 31 percent of the watershed is in two categories of good and very good potential.

The purpose of this study is to investigate the impact of sports spaces on the urban environment using GIS. This research is cross-sectional in terms of execution time and applied in terms of outputs, and is descriptive-analytical and comparative in terms of analysis. And the youth of Tehran, including areas 13-8-7-4. It also includes 48 sports complexes. Which was examined as a whole number. For this purpose, statistical data of 5 active stations in the study area including: course stations, crisis headquarters, petals, victory and Aqdasiyeh in the period from the beginning of April 1399 to the beginning of April 1401, were collected and reviewed. At first, the geographical location of pollutant measuring stations was determined and entered the GIS environment and became a shape file. Then, the research model was drawn using structural equations.Then, through the IO technique, the location layer of sports complexes and the zoning layers of pollutants were superimposed and maps were prepared and produced. The findings showed that most of the sports spaces overlap with polluting areas. On the other hand, the proposed model of sports space on the environment was sufficiently appropriate and showed the impact of sports space on the urban environment. The general public is concerned about environmental issues through sports, so that by implementing green sports, we can take a constructive step towards minimizing the damage to the environment.

This study was conducted to evaluate the opportunities and threats to the development of tourism services in Shiraz. This research is applied in terms of purpose and descriptive in terms of survey method. The first statistical population includes the managers and all experts of cultural heritage and tourism office of Fars province. The statistical population was responsible for identifying strengths, weaknesses, opportunities and threats in the Delphi method. The information required for this study, were collected and analyzed using three questionnaires. The first questionnaires, were distributed among the members of the first statistical community, led to the identification of internal and external environmental factors affecting the strategic decisions of the tourism industry. Questionnaire number two was designed based on Saaty scale and pairwise comparisons and was decided at the disposal of the group to calculate the relative weight of the groups of weakness, strength, opportunity and threat. Questionnaire number three was developed based on pairwise comparisons and Saaty scale to identify the relative weight of components and factors identified in each group by the decision group. Findings showed that Shiraz city should use three strike strategies (short-term), medium-term strategy and long-term strategy to deal with opportunities and threats to develop tourism services in this city.
