Factors such as rapid population growth, rural migration, industrial expansion, vehicular density, topographical features and natural factors have collectively contributed to Tabriz becoming one of Iran’s most polluted cities. Beyond human-related factors, geographical factors including location, topography, and temperature inversions also play a crucial role in exacerbating air pollution in Tabriz. In this research, descriptive research methods drawing from meteorological and air pollution data sources were employed to investigate the spatial relationship between climatic factors and air pollution in Tabriz. By collecting and analyzing information from meteorological stations in Tabriz and air quality measurement stations related to Tabriz, we created integrated maps using Geographical Information System (GIS) software. These maps visually depicted pollution distribution and zoning. According to the results of the research, a significant spatial relationship and correlation exist between meteorological parameters and air pollution parameters. Additionally, the distribution of air pollution parameters across the surface of Tabriz city reveals that the highest pollution levels, attributed to polluting gases such as SO2, NO2, O3, and CO, occur in the western and central parts of the city. Conversely, suspended particles contribute to the most pollution in the eastern side of Tabriz. Furthermore, the seasonal quality index indicates that summer and spring experience the least air pollution, while autumn and winter exhibit the highest levels. Manuscript profile -

One of the fields of research for controlling urban fires is to identify critical fire points in the region; Insufficient knowledge of these points will cause the occurrence and spread of fire in various areas and uses, delays in controlling it, and causing financial losses and personal injury as well as environmental pollution. Fire risk zoning with the aim of being used in planning and management in urban fire control has not been considered in the study area of this research and no research has been done in this field in the form of research and study plan. The purpose of this study is to determine and identify the criteria for fire risk zoning in the study area, to create a fire risk map based on the logistic regression method and compliance with the fire reality map, and also to present fire management programs and fire crisis management in Kashan.Materials and Methods The steps and techniques used in this study were performed in six steps. The first step is to identify the effective criteria and indicators. Using library studies, information obtained from authoritative articles, and also through the Delphi method in order to collect the opinions of experts, the Likert scale was used. In the second step, the screening of criteria was done in accordance with the purpose. The effective criteria in this study are vulnerable factors including (population density, industrial units, commercial-warehouse, high-rise buildings, old tissue, and fuel station) as well as the capacity of reducing factors. (Fire station, roads, and hydrant valves). In the next step, the layers were standardized using fuzzy logic. At first, the distance function was performed on the criteria in SELVA IDRISI to determine the distance from each phenomenon. Then, by the fuzzy method, all the criteria determined in the range of zero to 255 were standardized. The type of function used in the fuzzy logic approach is linear, and the selection of the function type and thresholds was based on a review of sources and expert opinion. In order to analyze the spatial relationship between fire incidents that occurred in the city and the role of effective factors in its occurrence, all fire points of the last 10 years in the city from 2010 to 2020 were extracted and turned into a raster map. In the fifth step, a Fire hazard map was prepared using logistic regression. After determining the validity of the logistic regression model using the specified indicators, the fire risk zoning map of Kashan was drawn. In the last step, Chi-Square, ROC, and Pseudo R Square were used to validate the logistic regression model.Results and Discussion Advantages of using the logistic regression model In addition to modeling observations, it is possible to predict the probability of each person belonging to each of the levels of dependent variables and the possibility of directly calculating the odds of variables using the maximum likelihood of maximum model coefficients. Also, compared to other statistical techniques, multivariate such as multiple regression analysis and diagnostic analysis, the dependent variable can have only two variables, one is the probability of an accident and the other is its non-occurrence. In order to analyze the spatial relationship between fire incidents that occurred in the city and the role of effective factors in its occurrence, all fire points of the last 10 years in the city from 2010 to 2020 were extracted and turned into a raster map. The output of the logistic regression model has coefficients between 0 and 1, with a probability higher than 0.5 of a value of one (occurrence of fire) and a probability of less than 0.5 of a value of zero (no occurrence of fire) and thus a boolean map of risk is generated. This logarithmic change causes the predicted probability to be continuous in the range of 0 to 1, and the output of the model to be presented as a spatial prediction map of the probability of destruction. Then, in the logistic regression equation, this layer was introduced as a dependent variable and the effective parameters in fire zoning were introduced as an independent variable. After entering the data into the logistic regression statistical model, model coefficients were extracted using effective parameters in IDRISI software. After determining the validity of the logistic regression model using the specified indicators, a fire risk zoning map of Kashan was drawn. Finally, in terms of fire risk potential, the study area was divided into 5 classes: very low, low risk, medium, very high, and high risk. The area of each of the 5 classes was obtained in hectares and the percentages were 87475.47, 4669.03, 132115, 1116.33, 788.96 hectares, and 90.94, 4.85, 2.19, 1.16, 0.82 percent, respectively.Conclusion The value of 0.95 obtained from ROC indicates a very high correlation between the independent and dependent variables. The value of the qi index is twice equal to 110836.07; Since its value is much higher than the threshold value, then the null hypothesis of all coefficients is also rejected. The value of the PR2 test in this study was 0.47, so the logistic regression model had an acceptable fit. Manuscript profile -

Therefore, in this MoreThe house and knowing its features have always been given a lot of attention and importance by designers and builders in order to increase the quality of human living place.House is an important social need that can be analyzed from different aspects. Therefore, in this regard, knowing and examining the roots affecting the houses of the past, including the physical aspects, can be an important and positive step in improving the quality of new and modern houses.The necessity of creating a house is its body, which has been recognized by many researchers. But the various investigations of the physical aspect to compare the spatial relations of the houses have received less attention, which is why this research has addressed it.According to the surveys conducted in the residential houses of the second Pahlavi period in Tehran, due to the increasing population growth and the increase in the migration of villagers to the cities, mass building is formed to meet the needs of the people, these gradual changes applied by studying the houses of each The decade of this historical period was summarized and analyzed separately.On the other hand, the existence of a multi-directional relationship between the text and the audience and the general culture and the connection of literary works with the existing approaches in the society, leads the research point of view to fiction literature, so that the process of house changes can be investigated from this point of view. In the context of the relationship between literature and society, we can mention the attention and influence of literature into people and society, and the special literary importance of this period was also due to the greater proportion of literary works of this period compared to the periods before and after it. Therefore, since the literary landscape refers to social issues and the realities of society, it seems that by rereading the literary stories of the second Pahlavi period, the gradual changes applied in the spatial relations of residential houses can be read and identified in terms of the physical dimension.The production of literary discourse and the flourishing of residential architecture also necessitates a deep study of the second Pahlavi period.The aim of the current research is to investigate the influential physical components in the different spaces of the houses of Tehran in the second Pahlavi period from the point of view of the literary writers in order to discover the important components of the houses from a new perspective. Also, this research has been done with a qualitative approach and a type of interpretative philosophy, with the approach of analyzing the content of the text and using the classical hermeneutic method, to examine and understand and explore the physical components of the houses of the second Pahlavi period from the texts of the books examined in a descriptive-analytical way. And finally, it has been dealt with by comparative comparison.The research tools were selected from the works of the writers of the second Pahlavi with a purposeful sampling of documentary studies.Finally, the results of the research show that the houses of the early Pahlavi II period are different in terms of physical and shape compared to the houses of the late Pahlavi II period. In the beginning of the second Pahlavi period, the open space of the yard and the porch play an important role in the house, which includes the pond and garden and different types of vegetation, but gradually with the removal of the yard and other architectural elements, including the porch, pond, garden and cover Plants, houses without these elements and sometimes even without a yard and as apartment units are observed. These changes show the gradual changes in the spatial relations of the houses of the second Pahlavi period, which shows the houses specific to that period by examining each decade.In this way, by removing or reducing and changing some elements and components from the plan of the houses, and despite changes in the spatial relations of the houses, the importance of the body and spatial relations in the houses of the decades before the 40s compared to the houses of the 50s and the new appears.

Space syntax technique is in fact the investigation of the relationship of every space unit in a set in the neighboring space; through knowing social structure of the relationships of the components, the pattern of systematic activities and also the semantic load and spatial relationships can be obtained. The research methodology of the present descriptive-analytica study is information analysis and of logical reasoning type. The qualitative and quantitative methods are employed in the formulation of the theoretical framework and the analysis of maps and modeling, respectively. The research results on 11 types of different plans from the residential units of this complex revealed the relationship between architectural space relations and configuration of architectural body and spatial depth in the definition for privacy. Moreover, the appropriate spatial relationships for achieving more privacy can be defined in order to be used in the plan design of condemnatory complexes. Manuscript profile
