Cancer is one of the most common causes of death worldwide. Always the role of natural and geographical factors in the manner and manner of distribution and its effects on disease centers and the role of natural processes in fundamental changes and humans as well as human-related diseases, even in places where these effects are clearly evident in the death or destruction of habitats and humans themselves; It has a pale appearance.

This research is based on field studies in terms of the nature of the applied goal and in terms of the descriptive-analytical research method. The statistical population of this research includes all patients with gastrointestinal cancer who were diagnosed between 2014-2017 and were registered in the Sima Cancer System (Electronic Management Integration System) and were permanently residing in Lorestan province. In order to achieve the objectives of the research, indicators related to the role of geographical factors in the spread of digestive tract cancer were extracted (average annual rainfall, vegetation cover, average annual temperature, average sunny hours, and climatic zones).In order to investigate the role of geographic factors in the classification and distribution of these indicators, one-sample t-tests, Pearson's correlation, and Friedman's test were used. In the following, ArcGIS software was used to explain the model through geographic weighted regression of use and the level and status of these effects.

 The results showed that the most important factor influencing the variable of cancer distribution was the vegetation component with a coefficient of 0.91%, which explains the influence situation well. Also, the results of the effect of geographical factors were such that Khorramabad and Borujerd cities had the highest effect, Kouhdasht, Delfan, Aliguderz, and Durood cities had a moderate effect, and Selah, Poldekhtar, and Azna cities had the least effect from geographical factors.

Today, the aging of the population is considered a big challenge for the cities and considering the increase in the elderly population in the near future, if this phenomenon is not properly recognized and planned to deal with it, it can become a social, economic and even political crisis. be at the level of the cities of the country. The purpose of this research is to investigate the general situation of aging in the cities of Gilan province, as the first ranking of aging in the country Informing city officials about the challenges caused by this new phenomenon on the urban space and planning to deal with it. The area studied in this research is Gilan province, where the urban elderly population has been investigated by city.

Documentary method and secondary data analysis were used in the current research. The statistical population of the research consists of the urban elderly of Gilan province.

The findings of the research showed that the cities of Gilan province have the highest rate of aging in the country, with an average of 7.5% of the elderly population; Among the cities of the province, Anzali city has the highest number of urban elderly in the province with about 9.9%. Also, most of the cities of the province are faced with the aging of the population and the prevalence of aging women is also evident in these cities. At the end of the proposals of this research, it has been achieved to provide solutions to deal with the consequences of aging and increase the role of the elderly in city planning as well as urban adaptation plans.

As a source of development, cities have faced an unfavorable cycle of inequalities due to inefficient structures and injustice has been formed in the distribution of services in cities, therefore, spatial justice in the distribution of services for fair allocation is one of the goals of planners. This research, which  have done with the aims to evaluate the spatial distribution of service devices  Gorgan city ;

 It is of applied type and descriptive-analytical in terms of nature and method.  The collection of information is based on library sources, documents and field studies.  SPSS software was used in the analysis of different parts of the research.  The reliability of the questionnaire is based on Cronbach's alpha of 0.834 and the statistical sample size is 384 citizens.  The scope of the study is Gorgan city with an area of   3560 hectares, which has a population of 353,000 people in the 2015 census. 

  The findings show that the indicators of meeting the needs of citizens, the unfavorable cycle of services and class distance respectively have the highest average level in the distribution of service places and there is a significant relationship between the distribution of service places and satisfaction in the study area.  In the analysis of the role of urban management in improving the condition of service facilities, among the selected indicators, the inefficiency of urban management was ranked first, informed management was ranked second, and optimal service delivery was ranked third, and the index of continuous monitoring was ranked last.  For the indicators of effective urban management in the distribution of service places in Gorgan city, they were selected based on Friedman's test, and at the end, suggestions were made to improve the service status of service devices.

The increasing importance of fossil fuels in the last century and the lack of non-renewable resources on earth has led to the extinction of human life. In recent years, there has been a shift towards cleaner methods where energy pollution from non-renewable sources is minimized. Each climate has its own conditions and characteristics, and this is the trend towards sustainable architecture in the traditional architecture of Iran. The importance of using energy to provide solutions increases at all levels. Due to its location on the sun belt, Iran is one of the suitable areas to benefit from the sunlight, and it is possible to increase the comfort function by taking advantage of the climatic features and the features of the traditional elements of sustainable architecture, taking into account efficiency and productivity. important indicators such as: orientation based on three institutionalized rune categories and models for city and house structure in Iran, walls in terms of materials and thickness, form of roofs, color and openings of external surfaces of traditional houses, etc. were used so that the amount of consumption It reduced the energy so as to be able to get rid of the environmental problems of the city.

The research method in this article is descriptive-analytical, and the library method was used to collect information and data.

By examining the theories of logical reasoning for the documentation of the texts, in this method it is tried to spread the qualitative and conceptual strategy issues in this research, and at the end of the research, the indicators of sustainability in the traditional houses of Iran were presented; As he got ideas and lessons from the energy efficiency of traditional Iranian houses to achieve a desirable design for today's modern architecture.

The indicators of desirable public spaces are also related to individual perceptions and social and cultural values, that these needs influence people's behavior in the environments in front of them and are one of the important factors of environmental quality criteria. The purpose of this research is to investigate the impact of urban design on the behavior of citizens (case example: Modares Street, Kermanshah).

The current research, in terms of the applied-developmental purpose and according to the nature of the study and the proposed hypotheses, the research method is descriptive-analytical (survey) and correlational. According to Cochran's formula, the sample size of citizens in Modares Street is considered to be 246 people. Also, the sampling method is a simple random method. In order to collect information and know the region, two library and field methods (questionnaire) have been used. In data analysis, statistical methods and Tukey's tests, one-sample T and Pearson's correlation were used.

The results showed that there is a correlation coefficient of 0.052 with a significance level of 0.008 between the variable of behavioral patterns and urban design in the direction of users' behavior in relation to space. This means that the two mentioned variables have a direct correlation with a confidence level of 0.99. Between physical and economic variables, there is a correlation coefficient of 0.135 with a significance level of 0.009. This means that the two mentioned variables have a direct correlation with a confidence level of 0.99. Also, the results showed that there is a correlation coefficient of -0.052 with a significance level of 0.008 between visual-aesthetic and environmental variables. This means that the two mentioned variables are not correlated.The highest degree of influence can be seen in social components and then in economic components with a close score, and the physical criterion has the lowest degree of influence in the influencing factors of urban spaces on behavioral patterns in the mental image of citizens

Sustainable and creative urban regeneration with an emphasis on compatible economic activities as an article tries to answer questions about regeneration. Considering the rapid process of urbanization and its effects on historical and dilapidated textures, more attention and care is felt in these textures.

In this research, an attempt has been made to collect case study samples to investigate sustainable and creative urban regeneration projects in developed countries as well as historical countries, and the information collection of these regeneration projects has been used to create a model suitable for this issue. For this purpose, a descriptive comparative table has been used to complete the information and create creative solutions.

Historical contexts have the highest cultural as well as economic potentials, in order to take advantage of them in line with the development of the region and also to prevent its decline, reliable and responsive solutions should be used. The following research is also in search of investigating these solutions and the feasibility of creative regeneration based on local economy in the projects of different cities of the world in order to fill the gap in the development of historical contexts, especially from an economic point of view. The results of this research indicate that the best and most comprehensive method for re-creation and better and optimal design of this historical context is the creative economy and its solutions, which include branding, increasing the relationship between tourism and industries, creating economic values, investing, creating or it is a change of use, therefore, the use of the desired approach and creative economic development in recreating the historical context will lead to its dynamism and economic and cultural development.

Considering the rapid process of urbanization and its effects on historical and dilapidated textures, more attention and care is felt in these textures. Therefore, in order to eliminate the created problems and inadequacies and to use the capacities hidden in them, the optimal solution of regeneration is used.In this research, creative urban regeneration policies are necessary due to the historicity of the center of the neighborhoods of most parts of the country, and it improves the process of preserving historical textures and prevents them from damage. If economic development solutions are not provided today to improve the economy of historical neighborhoods and revive them, in the near future these neighborhoods will become abandoned neighborhoods which will lose its values and become anti-values, as the experience of other countries also shows that not paying attention to this issue causes marginalization, loss of security and similar issues.That with appropriate planning and design, these issues can be prevented and these values can be preserved in these neighborhoods. For this reason, a set of case examples of successful urban creative regeneration in Iran has been collected, and a model for improving the structure of creative regeneration has been presented from the collection of these examples, and with the help of a descriptive comparative table, the extent to which these criteria have been achieved in the existing examples has been examined.

First, the course of development and the background and ideas of the topics related to the keywords such as urban regeneration and economic development will be studied and its features and indicators will be extracted and the implemented examples of investments in the historical context and existing patterns in the neighborhood and public spaces will be examined and the conceptual framework of the research will be presented.

Change and growth in our cities are happening very fast today. Some parts of the city have been able to adapt to these changes, but the historical neighborhoods, which are important parts and preserve the values and culture of the people and has the highest cultural and economic potential, have lagged behind these changes. In this research, an attempt has been made by examining different dimensions and aspects and studying the projects of different cities in Iran in order to fill the gap in the development of historical contexts, especially from an economic point of view, it has been possible to present a design model in line with economic-oriented creative regeneration. In order to achieve the research model, it has been tried to fill the gaps in the studies and researches of the researchers in this field to some extent and finally to obtain economic indicators and suitable solutions in line with the process of urban regeneration in historical neighborhoods.
