Highlights- Different approaches and policies have been adopted to confront spontaneous urban settlements, which have failed to stop the development process of these settlements.- The informal urban settlement needs to be politically approved in developing countries, such as Iran, as it will be involved in a significant part of the urbanization process.- Presenting a novel approach known as informal armatures, David Gouverneur attempted to adopt a futuristic, protective, realistic perspective on spontaneous urban settlements and to consider administrative, environmental, morphological, planning, and design issues.- In Sanandaj, it can be helpful to consider the informal armatures approach, given that three spatial layers of the spontaneous urban settlement have taken shape so far, and the city can develop in the eastern part of the city. IntroductionDuring the past few decades, there has been widespread immigration to urban centers of wealth for utilization of opportunities and better conditions in prospect due to the dominance of the city-oriented capitalist economy, shortcomings, and failures of governments and official markets, and inequality in southern countries. Along with the inefficiency of governments and urban planning systems in satisfying needs, particularly those for dwelling and employment, this trend has led to spontaneous urban settlements. Therefore, it is essential to provide low-income groups with dwellings and present solutions in accordance with the residents’ financial capability. David Gouverneur presented a novel approach in 2015, which came to be known as informal armatures (IA). He believes that spontaneous urban settlements involve numerous physical and social complexities, and to simplify, the environment, morphology, and administrative aspects need to be balanced. He states that the problems with these settlements can be solved by the people, local governments, and central governments. This research has investigated the informal armatures approach in Sanandaj, Iran.Theoretical frameworkBeyond the theoretical controversies in this regard, the IA approach presents a framework for spontaneous neighborhoods before the occupation of land with a preventive, futuristic attitude. This approach approves of spontaneous urban settlements’ innovative, innate socio-spatial features and adopts this as a point to begin improvement. The conditions that need to be met for a successful IA approach include pre-emptive and transformative nature (political acceptance of the informality, presentation of appropriate public land with participation from the public and private sectors, and instruction of staff capable of implementing the approach), consideration of physical and performative components, hybrid and multi-scalar operations, environment-friendly nature, consideration of flexible planning components, and adaptability to different site conditions. Moreover, corridors, patches, and custodians are major components in planning and design based on the IA approach.MethodologyThe paradigm governing this research is pragmatism, which some contemporary methodologists have considered the foundation of research methodology with hybrid methods. In accordance with this worldview, the conceptual framework of the research has first been extracted besides an examination of the theoretical views on the topic based on Gouverneur’s perspectives in order to provide the background. Then, it was investigated how the approach could be adapted to Sanandaj in line with the research purpose. The statistics required to apply the approach to Sanandaj were extracted from the censuses of individuals and dwellings and the village lexicons, and satellite images and location data on the current state of Sanandaj in ArcGIS were used for the analysis of the spatial conditions of the city.Results and discussionSanandaj is a city with particular topographic features and looks as if located in a space cup due to the highs around the city and the variety of hills inside it. It can be extended mainly on the eastern side. Moreover, three spatial layers of spontaneous urban settlements have taken shape in Sanandaj so far. The first layer is the fixed layer inside the city; the origination dates back to the period between the 1960s and 1980s and is regarded today as the distressed middle area of the city. The second layer involves settlements with backgrounds as villages located within the limits of Sanandaj, which are known today as unconnected urban areas and have been excluded from the informal settlement. A third layer is also taking shape around the city, given the barren lands inside it, including villages with growing populations. The investigations demonstrated that Sanandaj could be considered for pilot research on the application of the IA approach, given its features.ConclusionInspired by the international policies, different approaches have been adopted so far in Iran with respect to spontaneous urban settlements. However, these approaches have failed to stop the extension process of these settlements, and about twelve million of the country’s urban population thus resides in these settlements today. Moreover, all the previous approaches have mainly disregarded the important idea of future development of these settlements and the combination of the planning, morphological, and administrative components, while the IA approach has successfully filled the gap. The informal armatures approach can prevent fundamental problems, particularly in terms of infrastructure, in future spontaneous urban settlements through mutual government-people management and consideration of residents’ financial capability and planning tools such as the interconnection of corridors around the city, provision of patches, and protection of valuable land. Moreover, this approach can contribute significantly as one of the most effective futuristic, collaborative approaches (top-down and bottom-up), as it provides widespread coverage of informal urban settlement in Iran.

Introduction
The bond between the city and the movies is a two-way, strong one more than a century old. The movies has always been defined with respect to the city and urban spaces since the first days of its creation—late 19th century.
If the audience perceives urban spaces as having various functions and appropriate spatial qualities in the movie, the perception is associated with the real space and causes different feedbacks than those spaces in the long term.
Despite the increasing global desire to use the cinematic image of the city to achieve various layers of information, the Iranian movies still fails to present a correct image of the city. The beating heart of every city, urban spaces are still not used in the Iranian movies in the general sense.
While large, important cities such as Paris, London, New York, and Berlin are always in a two-way relationship with the movies and urban spaces, where the city and the various relevant issues are always exposed to cinematic representations as everyday, critical, or praiseworthy matters, reflection on such issues is still heretical in Iran. Especially, critical reflection about Tehran, as the main location in the Iranian movies, has not received much attention. A way to understand the urban space is to represent the city, urban spaces, and the complex, contradictory whole using the movies. Therefore, the main purposes of this research are to 1- examine the characteristics of different periods of the Iranian movies from the beginning of its formation to 2019, 2- examine different dimensions of selected works of the Iranian fiction movies after the Islamic Revolution of 1978, 3- extract urban space creation criteria in the fiction movies works, and 4- represent the image of a more human-oriented urban space in the Iranian movies. The latter suggestion is made because it is assumed that the Iranian cinematographer can achieve a dialectic of indicating the positive and negative aspects of the existing spaces in the country’s cities by using the correct criteria for representation of urban spaces in the movies, thereby nurturing informed, insistent viewers and causing active measures on the part of environmental designers to create more humane spaces.
Theoretical Framework
The final criteria were evaluated with the methods of analyzing the content, watching the movie, and surveying the city in the movie. Based on the conceptual model, the final criteria include the following in the order specified from the filmmaker’s point of view: the qualities of the urban space in the movie, diversity in the use of urban spaces, method of payment for the place, types of urban space, and types of character. The criterion of diversity in urban spaces, which concerns the use of these spaces in different parts of the city (not only in a specific region) with the urban surveying method in the movie, seeks the diversity of urban spaces presented in the city of Tehran in the fiction movies of choice produced after the revolution, and the final map is generated in the GIS software. 5 more criteria were examined first in the most important movies produced after the revolution with the method of content analysis and movie watching.
Methodology
In a comparative study, what can help the researcher to achieve his goal is greater emphasis on simultaneous analysis and examination of contrasts, as practiced in this research.
Findings and Discussion
All the above points indicate that the Iranian moviemaker still considers the city and its imposed modernity to be the source of many problems.
Another issue emphasized by Iranian moviemakers is to demonstrate the constant development of the city and its spaces regardless of the events of the story and peoples’ wishes. In some movies, no emphasis is placed on the urban space if actually depicted, and it is regarded simply as a background for the events of the story. All locations are focused on certain areas in Tehran and the like.
Conclusion
The results of the research demonstrate that we have not been very successful in creation of urban spaces in the past decades, and the few spaces that have been created and recreated have not been welcomed by cinematographers for various reasons. Moreover, the represented urban areas have been restricted to certain areas in Tehran, which has been subject to the conditions mentioned in the section on findings.
Furthermore, most of the selected movies in the fiction and urban fields were filmed in Tehran, and we are faced all around Iran with a pure centralism in terms of selection of the location of filming in urban spaces despite the availability of a variety thereof. This process should be corrected to address different aspects of various cities in Iran in fiction movies.

Highlights
- Realization of urban construction as a social construct forms a knowledge stock to mine theoretical concepts and develops the goodness of urban building governance at the same time.
- One of the most important categories in the identification and comprehension of actors’ behavior and expectations in the field of Tehran’s construction management in the context of the truth revealed in the study of everyday social life is the distinction between land developers as industrial investors (those whose capitals come mainly from built spaces) and land developers as commercial investors (those whose main capitals involve cash and who move between different markets to earn profit), along with the diverse role of real-estate agents as appraisers or marketers.
- A categorized, cyclical statement of assumptions about urban construction management is provided between the three principles of urban management, built environment, and land developers.
Introduction
According to the citizens, it is years that the urban physical space of Tehran has been characterized by uneven growth and increasing injustice, and its spatial development management is also described as inefficient by various experts. Urban construction is the act of creating a physical space to advance urban functions, and the city’s spatial organization is formed in solidarity with its continuity. Thus, management of the spatial-physical development of the city is a mission pursued by urban management, and the existence of an efficient, effective urban management, as a government infrastructure and an executive attempt to realize good governance and then sustainable urban development is a matter of consensus. By accepting the spatial inefficiencies in Tehran’s urban development and rejecting the gap between content and form, this research introduces its problem as an explanation and interpretation of how Tehran’s urban construction management system functions.
Theoretical Framework
Construction is always a different experience and creates a heterogeneous good. The literature review also demonstrates that each research has described urban construction from its own theoretical-philosophical perspective and background. In fact, the variety of theoretical approaches to urban construction held by political philosophies is accompanied by a unique resultant of the actuals at any time. Therefore, construction is introduced sometimes as the agent of meeting expectations and sometimes as the cause of the current conditions. This gives construction the status of a social construct. Due to the historical dependence of actualized behaviors on the institutional context and variation in functions, one should refer to the conceptual roots of the phenomenon to study the evolutionary path thereof, focusing on the dynamic, unbalanced behavior of social systems.
Therefore, an aspect of truth used to explain such a phenomenon that is created, lived, and understood by citizens is the spaces of representation or the part where the land developers (constructors) live the urban construction management system. That is, it is not the same as what the authorities assign to the construction through administrative instructions, nor as how the experts describe the urban construction management system. Rather, it is by being immersed in the path of building and functioning as a land developer that the unique spatiality of every society can be justified.
Methodology
Since urban construction management is recognized as a multiple, dynamic unit (mutual, continuous influence of constituent dimensions), abduction of the lived experiences of the active land developers requires immersion in data, which are collected through adoption of an intersubjective, empathic approach. Therefore, the strategy of this qualitive research is phenomenological, categorized under the interpretive paradigm. The research population consists of Tehran’s land developers who were selected using purposive sampling. Finally, eight in-depth interviews were conducted. Thus, the researchers clustered and finally combined the lived experiences to achieve a rich description while observing Epoché’s principles throughout the research. It should be mentioned that the thematic analysis technique was used for horizontalization, clustering, and classification of data.
Results and Discussion
As a result of the conducted interviews, transcriptions, and extracted concepts, 67 basic themes were identified in the first step after several rounds of editing. Then, the themes were classified under 17 organizing themes. In fact, an attempt was made at this stage to cluster the intersection of the basic themes, which was realized through movements back and forth between the holistic and detailed approaches and immersion in the data. The process was repeated to form global themes, and four were finally distinguished, including the basic assumptions regarding Tehran urban construction, land developers’ enabling factors, the inefficiencies imposed by the construction management system, and various stakeholders’ roles in the urban construction of Tehran and its consequences.
Conclusion
The findings of this study demonstrated that Tehran’s construction management system is based on different actors’ cooperation to transform space into financial value, according to land developers’ lived experiences. Although there are actors here who link this financial value to the use value due to their natural need, their expertise, or the functional nature of the space, their influence is generally limited to setting minimums. Therefore, these actors do not have a high power with respect to others to influence the production of spaces. Finally, the urban construction management system of Tehran can be explained and interpreted as the system sought to stabilize its position and apply authority to obtain its required income by developing the physical urban environment to carry on missions whose violation would have political costs or legal consequences. Moreover, these measures are taken based on inefficient processes and contents, relying on constructors’ assets and skills at the cost of commodifying urban spaces.

Introduction
The environment can cause positive and negative emotions in citizens. Emotions are important due to their impacts on people’s behaviors, because emotions make up a main component of social behavior, and extraction of emotional responses is one of the best ways to understand different fields of experience and perception. Nowadays, mental health problems and the emphasis on increasing social interactions have led to more and more concern for the subject of emotions, but the impact of physical-spatial factors has received less attention from the conducted studies. The aim of this study is to investigate the effect of the physical-spatial measures of urban streets on pedestrians’ emotional responses by placing the individual in a pseudo-real environment. Moreover, this study makes possible the use of a new neural measurement tool in urban studies and evaluates its accuracy.
Theoretical Framework
The review of previous studies demonstrated that the environmental parameters that can affect emotion include non-physical human factors on the one hand and physical ones on the other. The physical factors that make up the subject of this research can be divided into two categories: 1- non-artificial factors, i.e. green space, and 2- artificial factors, which include the size and enclosure of the space, the shape and form of the space, the characteristics of the surfaces including architectural style, the color and texture of materials, and the variation in spatial sequences. Given the number of studies conducted on the effect of natural factors and certain characteristics of surfaces in the field of architecture, the present research examined four physical parameters.
Methodology
Ten of the most important physical-spatial variables that make up different states and types of the spatial structure of an urban street, which can affect the individual emotions of pedestrians, were selected for investigation and used to design 18 tests. The research was conducted with a combined method consisting of: 1- a self-report method of Self-Assessment Manikin (SAM) images and 2- a neurological method using electroencephalography. In the EEG method, the single-channel MindWave MW001 headset, produced by Neurosky, was used as the instrument. The research population included 50 students of Tarbiat Modares University. The research was conducted with the help of controlled experiments using the mobile digital 3D modeling technique, which makes it possible for people to navigate the virtual street in the city. After the data extracted by the health and Stroop tests were confirmed, the data analysis was made using a quantitative-statistical method.
Results and Discussion
The findings regarding the shape and form of the space demonstrated that people feel more pleased in curved streets than in straight streets, and there is greater arousal in streets of the former than the latter shape. However, the level of control in a straight street is higher than that in a curved or spiral street. As for the size and enclosure of the urban space, the results indicated that there is greater pleasure in a street with medium enclosure (1:2 and 1:1) than in one with low or high enclosure (1:4 and 1:1.2), but streets with medium enclosure exhibit less arousal. Spaces with less enclosure cause people to have more control over the space. The results also demonstrated that the pleasure and arousal experienced by people is increased by the existence of the square as a spatial element and a landmark building as a physical element, permeability in the spatial structure of the street and brokenness in the path, and variation in the landscape of the street. It was only in the street with physical retraction and protrusion that no effect on arousal was observed, although the level of pleasure should increase. Moreover, the results indicated that the pleasure in the street with the curved corner was greater than that with the other forms. However, the shape of the street corner exhibits no effect on the arousal. Furthermore, the walls that are completely three-dimensional exhibit greater pleasure and arousal than those featuring walls with two-dimensional and three-dimensional rhythms. Finally, the walls that are completely two-dimensional have the least pleasantness and arousal. There is a higher level of control in the street with 2D rhythms than in that with 3D rhythms. The results also showed that visual permeability in the physical structure of the street increases the arousal and control of the space, but it has no effect on the pleasure. Another result of this research is that there is 75% conformity in the results obtained from the two methods of SAM and EEG, which demonstrates that the data (EEG) extracted from the device can extract people’s emotions well.
Conclusion
In general, the current research confirms the results of previous studies, but it precisely demonstrated by measuring the extracted neural data that the levels of emotional pleasure, arousal, and control are affected by the shape and form of the street, the size and enclosure of the street space, the presence of a spatial and physical element that creates attention and emphasis in the street, permeability in the spatial structure of the street, rotation along the street and perspective change along the path, two and three-dimensional wall street rhythms, and the shape and form of the corners of the street intersection. However, physical indentations and protrusions exhibit no effect on arousal, and visual permeability has no effect on pleasure. In addition, the results showed that the EEG data extracted from the headset (MindWave MW001) used in this study could well capture the emotions of individuals, thus making up a proper potential tool for evaluation of environmental design interventions in the field of architecture and urban planning. The results of the present study, which indicate the psychological effects of urban design of a street, help to select and design the appropriate elements and physical characteristics of the space, increase positive emotions and reduce negative emotions, and ultimately improve the mental health of citizens.

Introduction
In the past few decades, the social conditions of cities have changed the children’s urban life and imposed a huge impact on their freedom of movement and independence in the public realm. Moreover, many parents are caught in “social traps,” and are consequently more likely to restrict their children’s independent, active movement in the public realm. While Children’s Independent Mobility (CIM) originally focused on their independent travel to and from school, the concept has further expanded to embrace their independent, active mobility and play around their neighborhoods without adult supervision or accompaniment. Thus, this paper attempts to study the shared spaces in residential complexes, providing a child’s first independent outdoor experience, and identify the qualities that can contribute to and improve (CIM) in such areas.
Theoretical Framework
As an essential quality of a child-friendly environment, CIM is an indicator of children’s acceptance in the society, which provides them with the opportunity to be present in the public, play in the neighborhood without adult supervision or accompaniment, and interact with others and develop their social circles. It provides a wider variety of opportunities for socialization and hangouts among children and contributes to their sense of identity. Therefore, CIM is considered as an important quality that aids children’s physical, social, and cognitive development. The main factors that influence CIM include interpersonal characteristics, a sense of community and social environment, and the quality of the built environment.
With regard to children’s interpersonal characteristics, one has to take into consideration the importance of age and sex in their mobility and play patterns in the public realm. Children aged 8 to 12 years are more likely to receive permission from their parents to go out and play than younger children. There are also clear differences in the ways that boys and girls use and experience urban neighborhoods and spaces; generally, boys enjoy greater freedom of mobility and are more visible in neighborhoods and playgrounds.
The social environment of a neighborhood is influenced by the level of social cohesion, the existence of shared values and norms, a family’s mental image of their place of residence, their concerns about the presence of strangers, the likelihood of crime and delinquency, and child abuse in the area. In turn, it exhibits impacts on the level of independence that children might experience in their use of public spaces in the neighborhood.
The Physical characteristics affect CIM on two scales: the neighborhood where the residential complex is located and its shared spaces. At the larger scale of the neighborhood, the compact city form, which provides children with short distances between various destinations, increases their chances of active, independent mobility. Furthermore, such areas improve children’s sense of security in public spaces as they enjoy higher population density. In the shared spaces of residential complexes, the characteristics that are closely associated with CIM include density, pedestrian-friendliness, cleanliness, access to green spaces, and proximity to nature. One has to take into consideration that other environmental characteristics, including the climate conditions, air quality, and temperature affect the time for which children would like to stay and play in public areas.
Methodology
The research employed the grounded theory methodology to construct a theory from the collected data. Due to the necessity of obtaining insights from various groups of stakeholders, the data were collected through 107 semi-structured interviews to reach saturation. This included 53 children, 38 parents and caregivers, and 16 professionals. Given the importance of the physical qualities of the environment, direct field observations were also made in 15 selected residential complexes in Tehran. The qualitative data analysis was carried out through the MAXQDA software, where 74 concepts, 25 principal codes, and 9 categories were extracted. The codes and categories were integrated and optimized, and their relationship with the core of the research was specified.
Results and Discussions
The results of the data analysis demonstrate that the causal and intervening conditions of children’s independent mobility include the inadequacy of the legal framework and the inefficiency in implementation of plans and their monitoring and evaluation systems. Moreover, CIM is affected by the qualities of the social environment where children live, and the social acceptance and awareness of the community can thus play a role in promotion of CIM strategies. The results further reveal that strategies used to improve the social atmosphere within the residential complex in favor of more independent, freer presence of children include improvement of the physical qualities of the environment, involving attempts made to keep children safe and secure from all possible risks and threats, to plan for playful spaces, to facilitate access to nature and green spaces, and to keep the spaces clean and healthy. As a consequence, the children will enjoy higher degrees of mental and physical health.
Conclusion
Social traps and lack of responsive quality control and evaluation systems for child-friendly residential complexes emphasize the necessity to develop a qualitative framework to promote opportunities for children’s independent mobility and unsupervised play in shared spaces in residential complexes, while meeting parents’ expectations from the quality of the built environment to permit CIM within these spaces.

Introduction
An inherent characteristic of cities, segregation pertains to the social distance between residents and their physical separation. When this phenomenon prevents some groups from accessing services, activities, and spaces, it leads to urban problems. Due to the interdisciplinary nature and large scope of this phenomenon, many researchers from different expert groups have investigated it in the past three decades. Although the number of studies is not small, it is important to note the dispersion of the principles and topics and the lack of coherent conceptual frameworks as a result of the variety of relevant specialties. Therefore, the purpose of this article is to study the diagnostic status of the scientific Persian articles addressing the concept of segregation and to analyze the nature and quality of these research topics and present a systematic categorization thereof.
Theoretical Framework
The review of the literature shows different concepts proposed for definition of segregation. In the middle of the 20th century, segregation was first recognized as a social issue (Legeby, 2013), the main purpose of which is to investigate the distinction between two demographic groups (Feitosa et al., 2007) or the separation of several groups (Morgan, 1975; Sakoda, 1981; Jargowsky, 1996; Reardon & Firebaugh, 2002). In the 1970s, new studies were conducted for identification of the causes of the segregation of social groups, linked with spatial analysis (Morgan, 1975; Sakoda, 1981; Jargowsky, 1996; Dupont, 2004; Lima, 2001: 494; Reardon & Firebaugh, 2002; Smith, 2009: 682; Romero et al., 2012: 76).
Depending on whether one has the freedom to choose to separate, segregation can happen in two ways: voluntary and involuntary (Izadi et al., 2016: 83; Lotfi & Ghazaei, 2019: 20). Therefore, segregation includes various dimensions, such as socio-economic and spatial dimensions, in which terms it has been investigated in recent studies under the title of socio-spatial segregation.
Systematic review is made using regular methods to identify, select, and critically evaluate the conducted research and collect and analyze the obtained data in order to respond to a specific question (Crocetti, 2016: 3). A function of this technique is to examine the history of the research and extract and summarize it to improve the approaches to the study to obtain appropriate results (Ghazi Tabatabaei & Vadadhir, 2010: 59). Generation of the meta-analysis involves the statistical analysis of a large set of results from individual studies, which is performed for integration of the findings (Glass, 1976: 3). Although this technique is usually considered as part of quantitative methods, however, it can also be used for qualitative approaches (Tizchang & Azam Azadeh, 2020: 10).
Methodology
The qualitative research approach is adopted here. The method of data collection is based on the basic text type using documentary methods. The systematic review and open coding techniques were used for data analysis, followed by qualitative meta-analysis. For this purpose, 50 Persian articles based on the topic of segregation and published from 1996 to 2021 were selected and reviewed in 15 categories. The research was conducted in four stages. First, all available information from the selected studies were collected and summarized. Then, classification and coding was performed based on the evaluation parameters (principles and categories) in two groups of structural and content features. Next, all the information extracted from the studies were processed, analyzed, and interpreted based on their frequency and percentages. Finally, the research questions were answered.
The structural section sought to investigate the general characteristics of the selected articles to explain the state of research in the field of urban segregation in Iran using the results. The content section attempted to outline the researchers’ views of the original concept, research method, type of research, attributes used for segregation, type of main question, thematic principles, and aspects investigated in the field of segregation.
Results and Discussion
The findings helped to categorize the selected articles based on the types of their main questions (what, why, and how) in the form of 5 main thematic principles. These principles include investigating the concept and methodology of segregation, examining the lived experiences of residents, identifying background factors affecting the formation of segregation, and investigating the relationship between segregation and contextual factors affecting it. In addition, the evolution of the concept of segregation in the research conducted in the field was divided into four general periods: early, middle, late (current period), and future, which were then compared. Socio-spatial separation was defined on that basis. The results demonstrate that segregation is an interdisciplinary, multifaceted, context-oriented issue involving socio-economic, physical-spatial, and political-management dimensions. In the current research conditions of the country, there is need for qualitative research on subjects such as conceptual and measurement modeling of segregation (to explain what it is), identifying and investigating the background factors affecting segregation, including the structures and compositions of cities (to explain why), and identifying and examining policies and trends effective on segregation (to explain how) considering all the dimensions. In this case, it is possible through a correct understanding of the concept to more precisely investigate its spatial patterns over time in the fields of urban development, planning, and design.
Conclusion
Since segregation is an interdisciplinary discourse, many researchers from different fields have investigated it from their specialized perspectives. The necessity of using methods such as meta-analysis can be explained by the large, increased amount of available research, the authors’ different views of the subject, and the need to summarize and combine them and to identify the repetitive and problematic research areas. The results of the research demonstrate that there are still many ambiguities about the meaning of segregation despite the abundance of research and urban science experts’ greater concern in the past ten years. This is confirmed by all the results highlighted in this research, concerning the use of different Persian translations of the concept, multiple attributes involved in its description, and unclear optional or mandatory aspects of the phenomenon. Therefore, it is necessary to review the multifaceted phenomenon of segregation in Iran in the form of new issues, taking into account its wide range of dimensions, to obtain a better, more accurate, more comprehensive understanding thereof.

Introduction
The advent of the information age in the 20th century due to the great changes in the field of information and communication technology (ICT) has led to the prevailing approach to maximizing the solution of urban problems for advancing urban planners, designers, and policy-makers. The rate of growth and extensive development of urban studies has provided a wide range of interactions between its different sections. Coinciding with its growing trend, the corona virus has been spreading around the world since December 2019, re-examining the role of ICT.
Theoretical Framework
There is a lack of domestic research on ICT and the city. Given the existence of the gap and the importance of considering the area in urban studies, the purpose of this article is to identify, extract, and provide an interactive research space between the development of ICT and the subfields of urban studies in order to introduce and classify topics, approaches, methods, and results.
Methodology
Using the method of systematic review, the content of published foreign scientific research was reviewed and analyzed. This was carried out with a search for valid articles, a study of the abstracts and research results of more than 150 articles and their review, and a final selection of 93 articles after entering them into the Excel software environment.
Results and Discussion
The selected articles have been published in English in the period of 30 years between 1990 and 2020. Monitoring, examining, and extracting the key themes of the articles led us to 8 categories, including 1) urban policy, 2) electronic participation, 3) smart city, 4) city structure and spatial organization, 5) travel behavior, 6) digital gap, 7) public space, 8) and competitiveness, and 30 sub-themes. About 90% of the articles have been published in reputable scientific journals, and the rest appear in books and conference proceedings. An examination of the frequency of articles shows the growing worldwide trend in concern for this field in urban studies in recent years. According to the analysis made in the research, the use of ICT is applicable to planning theories at all levels, including the two levels of access and data processing and communication independent of time and place. These technologies enhance and promote the development of networks, social cohesion, and smart development of the city. The digital gap is intrinsically related to digital and urban inequalities. In network-oriented cities and societies, the issue of communication poverty is as important as traditional poverty. Many discussions have been raised by researchers on the impact of ICT on the structure and spatial organization of the city. Despite the initial premise of using the technology, which was to reduce concentration and increase urban dispersion, two more approaches, the centralization approach and the dual approach, have also been proposed in the field. The development of ICT has profound consequences on urban economic competitiveness. ICT is the basic driver for smartness in cities. A provider of access to the transfer of information and planning tools, granting the opportunity to share modes of transportation and work from a distance, the technology is of considerable importance for transportation systems. The relationship between the urban public space and technological developments and the development of ICT with the spread of the corona virus has been taken into consideration. Recent studies show that the spread of the corona virus has multiplied the use of ICT, which will definitely change the severity of its impact on the city and urban planning and design more rapidly. Therefore, this article is presented in order to explain the various dimensions of this issue.
Conclusion
Given the application of ICT in the field of urban planning, it is comprehensible that the creation of links with urban planning and design has proceeded slowly despite the increasing development of telecommunication technologies. It is necessary to consider the complex relationship between the city and ICT. On the one hand, the relationship has raised the challenge of polarization, inaccessibility, and urban injustice, and on the other hand, it has involved benefits such as increased participation and social networking, urban innovation and creativity, and urban sustainability and intelligence. In fact, it is necessary to fill the gap between ICT and urban planning. The central solution framework of the smart city is based on the city rather than intelligence. One of the most important challenges discussed in the previous studies is the issue of accessibility among different social classes. In spite of the initial hypothesis that the importance of place is reduced as that of distance decreases due to the development of ICT, place still matters. The point to be considered in regard to the relationship between the density and spread of the corona virus is the absence of a direct relationship between its population density and death. In fact, the ever-increasing development of ICT and the persistence of policies of closure and maintenance of social distancing during the pandemic are themselves factors effective in the development of digital facilities and technologies in the city. Urban spaces are changing and transforming due to the development of new technologies. In fact, the urban space paradigm established in 2020 promises the emergence of virtual open spaces. Future studies will be focused especially on an understanding of the shift towards the digital space and the emergence of a combination of the real space and the virtual space in developed countries. Moreover, it is necessary to know the social dimensions of urban spaces according to the conditions imposed by the corona virus in order to understand the type and method of changing the shape of the public space of the city and social interactions. Finally, the study and review of the valuable articles published in the area of the interface between the city and ICT has raised wide, diverse issues that require familiarity, mastery, and theoretical specialization besides their practical applications for policy-makers, planners, and urban designers and managers.

Highlights:- The right to the city is a human right that concerns citizens’ possession of the city and their participation in city affairs, regardless of age, gender, race, nationality, ethnicity, or religion.- Children are a group of citizens who should be considered in urban planning due to their special physical and psychological conditions.- The four-part model of “Child’s Right to the City” includes the urban governance system, social inclusion, spatial access, diversity and vitality, and relevant components.- The components of the concept of the child’s right to the city are effective in improvement of the quality of urban spaces for children. IntroductionThe right to the city is an issue of social, political, and legal nature that, based on the concept of citizenship rights, demands a set of rights for all city residents to use urban life in a transparent, fair manner. Urban spaces occupy a major part of the time and space of people’s daily lives, and they have young audiences who are much more influenced by environmental factors than adults. Therefore, a part of the function of an urban space should be assigned to children, which makes it particularly important to properly design urban spaces for children as citizens and future builders of the city. The presence of children in the public space of a city provides them with appropriate experiences, including acquaintance with urban geography, appropriate social relations with peer groups, appropriate physical mobility in a wider space than the limited space of the home, enhancement of the sense of belonging to the place, city, and neighborhood, and acquisition of identity through the sense of place. Since children have psychological needs that are much more complex than biological and physical needs, the design of urban spaces taking into account the psychology of development and children’s mental characteristics, health, and safety is effective in fostering creativity and strengthening the sense of cooperation and children’s education. Despite the global attention paid to children’s issues and useful international movements, there is less concern in our country for children’s specific issues in the urban arena, and children in cities are faced with many special problems in terms of age and physical and mental conditions, such as non-observance of basic rights, lack of security and safety, insufficient facilities and spaces for activities and games, and consequent lack of feeling of belonging to the space. As residents of the city, children’s right thereto has been neglected in many cases by decision-makers, planners, and even other citizens. Due to the dominance of the ageist culture, children are always ignored in planning and decision-making, and they are left out as isolated, unqualified people in an understanding of their priorities and needs.Theoretical FrameworkThe right to the city can be defined and claimed for all its residents. It emphasizes two main rights. The right of allocation is defined for anyone who lives in an urban space on a daily basis, regardless of their nationality, gender, and age, and the right of participation is used to apply the opinions and mental ideals of space users. Children and teenagers are also daily users of urban spaces, although the type of space use by children and teenagers is different due to their age conditions and the restrictions on their independence. However, their right to the city and urban spaces should be recognized, and methods should be provided for their participation in definition and change of the urban space.MethodologyThe purpose of this article is to examine the concept of the right to the city and to identify the factors that are effective in improvement of the appropriateness of the urban public spaces for the presence of children. For this purpose, both qualitative and quantitative research methods were used. Since both types of analysis are interpreted sequentially, the present article falls in the category of sequential-exploratory research. For analysis of the qualitative data, meta-synthesis and Grounded Theory were used, along with the NVivo software, employed to code the data. The data collection method involved documentary research and semi-structured interviews. The multiple regression test was used to investigate the relationships and the level of support between the components of the child’s right to the city and the quality of urban spaces.Results and DiscussionIn this research, the urban space quality index was considered as a dependent variable, and the components of the child’s right to the city (urban governance, social inclusion, access to spaces, and diversity and vitality) were regarded as independent variables. On that basis, the urban governance component involves 35.5% of the improvement made in the quality of the urban space in order to realize the child’s right to the city, and the other components include social inclusion, spatial accessibility, and diversity and vitality, with 31.2%, 28.9%, and 14.6%, respectively. Moreover, the influence of each of the sub-components of the child’s right to the city on the quality of urban spaces and the corresponding correlation were investigated separately.ConclusionBased on the four-part conceptual model, the four main zones of the concept of the child’s right to the city include urban governance, social inclusion, spatial accessibility, and diversity and vitality, which make up four consecutive steps to the final goal of the research based on frequency. The sub-themes exhibit a hierarchical structure. In the zone of diversity and vitality, for example, it can be inferred according to the concepts of the right to recreation, safe spaces versus security spaces, social interactions, and collective life that concern for creativity should be realized so that the environment can be considered memorable to be capable of completing the above zone.
