Cinema is a novel platform for re-reading the relationship between the body and the mind of the contemporary city. Assuming little attention to successful, humane and spatial urban spaces in Iranian cinema and on the other hand the importance of the director's role in using the correct criteria for showing urban spaces in the film and successful representation of humane urban spaces in this study Objectives 1. A Study of Different Dimensions of Selected Works of Iranian Fiction Cinema after the Islamic Revolution of 1978 2. A Study of Different Dimensions of Selected Works of International Fiction Cinema 3. Extraction of Criteria for Creating Urban Space in Works of Fiction Cinema Follows. The theoretical framework of the research was collected based on the documentary method and the final criteria used in film analysis were 6 items, respectively: Urban spaces and character type]. In the selection of films using the Delphi method, interviews with filmmakers and university professors were used, and based on this, 5 foreign films by the famous director Woody Allen and 53 domestic films in the cinema after the Islamic Revolution were selected. In the analysis of films, two methods of content analysis based on the subject and subject of representation and the method of constructive content analysis based on semiotics have been used. The results of the research show that Iranian cinema has not allowed the presence of urban space, so it is necessary to start moving from cinema to city so that cinema can establish more communication with people and help the city and urban spaces to better understand. Based on this, suggestions are made to create more humane sequences and better representation of the city in Iranian cinema.

Today, the issue of residential mobility in different parts of the city, due to the inevitable cause-and-effect relationship between residential displacement and its spatial social structure, has been considered, especially in the analysis of social geography of cities. But despite the significant impact of residential movements on the social spatial structure of the city, less attention has been paid to the issue of relocation factors and residential instability and the desire to relocate, especially in the environmental quality of residential complexes and why relocation Residential, in order to achieve the governing laws, has a special necessity and importance in urban planning, design and implementation and foresight. The purpose of this study is to discover the factors affecting residential instability and the tendency to relocate, especially in the quality of the environment of residential complexes in Arak by residents. It has been done in Arak city during the period of March 2017 to July 2016. Participants in this study were selected through a cluster random sample, and for a more detailed study, the complexes were selected as towers, multi-block and single.
The results showed that causal conditions have the greatest impact in the first place and in the second place, intervening and strategic conditions affect residential stability. Causal conditions (such as design and construction of the building) are formed before the construction of the complex and other conditions One of the background conditions (such as the location of the complex in the city) after the construction of the complex is involved, which includes intervening and strategic conditions. Strategic conditions such as a sense of security and tranquility, congestion and management and intervening conditions such as neighborhood relations, cultural level and social homogeneity of residents, lack of economic capacity to move and lack of buyers due to poor building conditions (which are mostly personal and individual It is effective and different for each person) are factors that affect residential stability and the desire to move.
The results also showed that the factors that create residential stability are different from the factors that create the desire and tendency to move, and the reason is that the factors that create residential stability are commented on based on facts and needs, but the factors that tend to move based on desires are ideas. Flags, ideals, and minds are expressed, and the greater the distance between the two (real desires and aspirations), the greater the desire to move. For example, in residential stability variables, the highest frequency is related to good building quality with a frequency of 286, while in the study of residential relocation variables, achieving a larger apartment with a better yard and a quieter and better neighborhood with a frequency of 227 Has the largest number.
Accordingly, good building quality and cultural level and homogeneity were the first and second priorities of residents in residential stability. But the important point is the high level of reference to peace and security, proper access level, good management and economic inability to move, which have been important reasons for the respondents. Other cases mentioned include the good location of the apartment and the complex. Also, interviews with residents of residential complexes showed that access to apartments with a larger area is more important for the relocation of residents.
The section on causal conditions includes structures, architecture and electrical and mechanical installations, facilities, green and open space, and the quality of materials and execution. The aim of this dissertation in reviewing this research is the architectural design, green and open space section. The architectural part consists of two parts: design and execution. The execution part includes suitable and quality materials and the manner of execution. In the design part, the factors that are very important for people in terms of residential stability and desire to move are presented in this research.

Introduction
Because of the expansion of cities, it has become highly challenging to modify urban structures to address the drawbacks of the planning and design of open spaces, control microclimates, and improve thermal comfort conditions. Due to their effect on the quality of air in cities, urban microclimates are highly significant, and since urban spaces play an important role in creation of urban microclimates, urban designers and planners have the capacity and means to reduce the negative effects of climate on citizens’ health through implementation of proper designs.
Theoretical Framework
Urban spaces affect their users’ thermal comfort via their design elements. Various parameters can induce micro-climatic changes, such as the geometric patterns, vegetation, natural elements, and construction materials of the open spaces. These elements also play important roles in balancing urban thermal comfort during winter. While the effects of vegetation and geometric patterns on thermal comfort in public open spaces during winter have been studied independently, the cumulative impact of vegetation and geometric parameters during winter in cold and dry climates has not been investigated sufficiently. This article sought to address this shortcoming.
Methodology
The ENVI-met software was used for simulation and comparison of the thermal comfort conditions of the open spaces selected for this study. First, the design parameters of the selected sites were determined via field measurement, and were entered into the software for simulation of the thermal environments. The four climatic parameters of thermal comfort were measured during winter using ENVI-met . Then, a receptor was placed at the center of each selected site for investigation of thermal comfort at the pedestrian scale. Using these receptors, the parameters of space design and their impacts on thermal comfort were studied during the selected season.
Results and Discussion
The changes recorded for wind speed were larger than those in MRT, air temperature, and RH; hence, the differences in thermal comfort at the central points. According to the results, the Kolapa and Kolanj neighborhoods exhibited more favorable thermal conditions due to their higher PET values. Both Kalpa and Kolanj neighborhoods had north-south orientation. This type of orientation provides top-down access to the sunlight during winter. The H/W ratios at the central receptors of the Kolanj and Kalpa neighborhoods were 0.6 and 0.3, respectively. These H/W ratios provided greater enclosure than those of the other neighborhoods. While a H/W ratio less than one can be said to be suitable for cold climates during winter, it can cause thermal discomfort against wind speed if it lies below a certain threshold. This condition was observed in the Kababiyan neighborhood, where the H/W ratio at the central point was 0.13. As a result, the residents have to take protective measures against the winter wind and storms. In addition, dense vegetation caused a decrease in the SVF of the neighborhoods. The neighborhood centers with vegetation exhibited higher MRT values as well. The trees also raised the RH values of the neighborhoods. Because of the dry climate of Hamadan, Iran, vegetation can certainly improve thermal comfort in this city.
Conclusion
Recent climate studies have explored thermal comfort as an important quality of urban spaces. While thermal comfort can be achieved through a decrease in temperature in hot climates (as emphasized by most studies), it requires an increase temperature to provide thermal comfort in cold and dry climates. The presence of Hamadan’s citizens in the urban open spaces of the city always decreases in the second half of the year because of the cold mountainous climate. Limitation in or even lack of thermal comfort is one of the most important reasons for this change. With their high standards of sociability, the centers of the historical neighborhoods of Hamadan have always served as places for social interaction between the residents of the city. Therefore, this study attempted to assess the thermal characteristics of nine neighborhood centers in Hamadan using the notion of thermal comfort and the relevant variables.

This study addressed the relationship between high-rise buildings (as part of the urban environment) and mental health (one of the three major aspects of health: physical, psychological, and social), investigating citizens’ points of view on the high-rise Saeedieh Condominium in Hamadan, Iran. The research sought to capture the influence mechanism and to help reinforce the insight of designers of such buildings into and their concern for features of the built environment from citizens’ perspective that can inadvertently affect their mental health. In recent decades, construction of high-rise buildings has been appealed to widely as a method of construction, replacing the horizontal growth of cities. However, it seems that vertical urbanism has paid little attention to citizens’ psychological aspects in urban spaces. Height is an intrinsic part of high-rise buildings and their most important formal feature, with a significant impact on citizens and their eventual perceptions and emotions, which makes it significant to scrutinize its influence. One of the most important issues is the impact of high-rise buildings on citizens’ mental health. Mental stresses constantly threaten human mental health, in part due to inappropriate urban environments and residences. This increases the significance of examining the urban environment to reduce the existing stresses. The purpose of this paper was to present better ways of designing high-rise buildings considering their impact on citizens’ mental health as well as to identify how the influence works. Therefore, the main questions of the study are as follows. What relationship is there between high-rise buildings and citizens’ mental health? How can height affect citizens’ mental health? In the present study, a qualitative approach was taken using the method of Grounded Theory. After in-depth interviews made in person with citizens, the transcripts were summarized and encoded in the three open, axial, and selective stages, and the grounded model was finally extracted by the MAXQDA data analysis software. The participants in the interviews included 24 citizens, 13 men and 11 women aged 17-65 years. Theoretical consecutive purposive sampling was used, where sampling would continue until adequacy (saturation) was achieved for theorization. It should be noted that saturation was achieved as felt by the researcher with comments from 8 men and 8 women—a total of 16 participants—, but the interviews continued, amounting to 24 with 8 additional ones, which served to ensure the achievement of saturation (although no changes were made in the eventual data). The findings demonstrated that high-rise buildings cause mental pressure in citizens due to issues such as improper enclosure, physical-visual consequences, sub-climate generation, landscape restrictions, social difficulties, overlook, urban area heterogeneity, and negative environmental effects and citizens’ long-term involvement in emotional reactions resulting from the mental pressure affects their mental health. With a frequency of 73, the issue of improper enclosure was found to be the most popular among citizens in the set of situational issues, playing a major role in the emergence of the interactive issues and the consequential ones as a result. It was followed by the issues sub-climate generation (with a frequency of 57), physical-visual consequences (with a frequency of 55), landscape restrictions (with a frequency of 30), urban area heterogeneity (with a frequency of 25), overlook (with a frequency of 22), and social difficulties (with a frequency of 12), in that order.

Cities landscapes are exposed to observer judgments. However, the important thing point the public perception and reading of urban landscapes by urban space users. Since there is a variety of comments and opinions regarding city issues and the urban landscape and its priorities, and decision making should converge in order to cover all aspects of priorities, in this study an attempt has been made to explain the effective dimensions and factors of reading street landscapes. Furthermore, priorities of each of the sites were studied from the perspective of citizens in order to improve the quality of urban spaces in Hamadan. A qualitative research methodology was used; in terms of the study objectives applied research was used and in terms of the techniques employed, field observations and library study was usedto develop a conceptual model associated with reading the elements and aspects in terms of urban spaces. Finally, to examine and analyze the conceptual framework, expert questionnaires using the software Super Decision and the Network Analysis Process Model was analysed to give suitable answers to the following questions of the study: 1- What are the dimensions and components of reading street landscapes? 2- How do priority indicators and criteria affect the landscape of urban streets components according to experts? 3- According to what order are priorities and central streets of Hamedan organized based on parameters mentioned by? Based on the research, reading components of street landscapes can be both objective and subjective and three dimensions are presented: aesthetic (objective - subjective), semantic (perception, functional) and activity. In addition, 59 indicators were classified. Prioritizing landscape reading components in of Hamedan city streets based on citizens' viewpoints are shown below Bu-Ali Sina Street is first and has a weighting of (0.246) for quality readings of street landscape view and Shohada Street is last with a weight of (0.099). In this regard and in order to improve the urban landscape loci recommendations, such as improving street visual order, organization of walls and ancient buildings, paving the way for the presence of street art and graphics, defining and developing signs physically and semantically which isdesirable for promoting citizens’ reading of the spaces provided, can be studied. Based on the analysis and findings of the research, design and urban landscape management officials need to act in such a way as to maintain the initial values of urban design issues when making changes and new developments. Changes and new developments in urban spaces should be based on the social values and culture of the society and the target audience’s perspectives (citizens) to promote the values of leadership and guide the quality and quantity of space.

Nowadays, a faster pace of changes and transformations in different phenomena such people's lifestyles has meant changes in their thinking and needs also. Since people’s lifestyles are more oriented toward isolation, it is more important to reflect at their lives collectively. People's need for places of social interaction and meeting psychological needs have become one of the requirements of urban life. Public spaces are the only spaces where all citizens of every class, age, race, and association have the right to use without any limitation. Environmental quality of urban public spaces is one of the focuses of recent urbanism research and attempting to create an urban public space that meets users desires behavior has always been considered as one of the main strategies of urban projects. Urban parks as a part of public spaces in cities have a fundamental role in resolving human needs. Most urban theorists believe that urban parks are one of the main components of an urban system because in addition to their functional role they increase socialization in urban spaces. Thus, in order to make these spaces more dynamic and to meet the needs of the people, the behaviors shaping the spaces should be noted and examined. Since most parks’ compliance with the needs of users and environmental qualities is, there is a need for a systematic program based on the behavior of users. Furthermore, issues such as neglect of social values, cultural - identity values, and the neglect of physical and structural values have lead to the formation of public spaces that do not meet people’s needs in urban areas. In addition, neglecting to improve the environmental quality of urban public spaces such as urban parks, not taking into account the effective qualities of urban transportation and connections, and the exclusive emphasis on the subjective perception by urban planners and designers has resulted in the formation of urban areas which does not have the capacity to be responsive and flexible in the accordance with people’s expectations and behaviours. For the purposes of this research, Mardom Park in the city of Hamadan was selected as a case study. This study aims to identify and assess the stimulants and patterns of user behavior in terms of their needs and the environmental quality of urban parks. This study was based on fieldwork with a cross-sectional approach and seeks to answer the following question: “what effects do behavioral patterns and domains have on improving the environmental quality of urban parks?” In this study, in order to provide a conceptual framework document-based research was carried out, theoretical issues explored in detail and then analyzed using existing approaches. For this purpose, in addition to the qualitative analysis of urban spaces and behaviors formed in space because of spatial characteristics, quantitative analysis of indicators using questionnaires was used. The quantitative indicators was analyzed by SPSS. The results show that the quality and amount of the influence of environmental quality factors on the quality of activities, which are primarily behaviors or behavioral patterns, are not the same. In addition, the analyses outcomes show direct influence of behavior on environmental quality and environmental quality on behavior. The results indicate on the one hand, human needs are the outcome of behaviorial influences on space and environment and the ability of underlying environment. On the other hand, enhancement of environmental quality and influence of environmental factors on areas and behaviorial patterns in urban parks are not only a quantitative and technical concepts.
