Factors and stimuli that influence convergence and divergence play a crucial role in determining the process and quality of national cohesion. These factors and stimuli are not synonymous; rather, they are interconnected and mutually influential variables. Understanding the impact of convergence and national cohesion on overall security is of utmost importance. This study aims to investigate and analyze the factors and stimuli that affect national convergence and cohesion in the southeastern region of the country. Similarly, this article seeks to address the fundamental question of the primary factors and stimuli that influence convergence and cohesion among the Baloch people in the southeast. The research findings indicate that various factors significantly impact the convergence and divergence of the Baloch people in the Sistan and Baluchestan province. These factors can be classified into two categories: internal and external stimuli. The study underscores the significance of factors such as mutual trust, decentralization, concentration of industries and decision-making centers, strengthening ethnic identity in alignment with national identity, the role of historical documents in promoting national cohesion, the cultural center of the Baloch people in southeastern Iran, common social customs, and the positive influence of ethnic and national elites. Additionally, the study recognizes the influence of regional political tensions, historical economic ties with neighboring countries, and the prevalence of border markets with Afghanistan and Pakistan as significant factors that shape convergence, divergence, and national cohesion among the Baloch people in the Sistan and Baluchestan province in the southeast of the country.

Protecting the borders and establishing security and defense in the border and internal areas of every country has been the concern of the rulers of their time. To some extent, all countries throughout history have faced insecurity, chaos, crisis and war at the borders to stabilize their country. In the past years, many ethnic, racial and religious groups have lived side by side in unstable political and social frameworks and have lived on the borders. Throughout history, the country's border strips have seen the most significant conflicts and confrontations between governments and nations; therefore, the issue of borders has always been one of the basic and important issues of governments, so borders have a special place in every country. One of the most difficult tasks of any government is the control and security of political borders, and if this issue is not paid attention to and there are no appropriate plans and solutions, the country's political sovereignty will be threatened. In order to turn threats into opportunities and benefit from conditions and situations in order to maintain security and secure national interests, we must have a deep and comprehensive understanding of the level of border areas and its surrounding spaces. In the meantime, one of the most important measures is planning according to the geomorphological capabilities of the border areas. One of the measures that increase security in the border strip is to identify areas prone to establishing military bases and surveillance centers. Considering that the border strip of Kurdistan province, including Marivan city, has a sensitive location, therefore, in this research, the areas prone to the construction of military bases and observation centers in this city have been identified.

In this research, according to the subject and objectives, library information, SRTM 30 meters high digital model and digital layers of information have been used as research data. The most important research tools are ArcGIS (for the purpose of preparing necessary maps) and Expert Choice (for the implementation of the AHP model). In this research, in order to identify the vulnerable areas of Marivan city against the enemy's influence, as well as areas susceptible to the construction of military bases and observation centers, the integrated model of fuzzy logic and AHP has been used. This research has been done in several stages. In the first step, the parameters used are identified. In the second step, the used parameters are fuzzification. In the third step, using the Analytical Hierarchy Model (AHP) and based on the opinions of experts, weight has been given to the information layers and then the obtained weight has been applied to the information layers. In the fourth stage, the layers of information are combined and finally, a map of areas prone to enemy infiltration and areas prone to establishing military bases and observation centers is prepared.

In this research, in order to identify vulnerable areas against enemy infiltration, 6 parameters of height, slope, field of view, distance from the river, distance from urban areas and distance from military bases have been used. Also, considering that the study area corresponds to the border strip, therefore monitoring and controlling these areas is very important. One of the ways to control and monitor the border areas is to create military bases and observation centers, which has been addressed in this research using 6 parameters. Investigations have shown that Marivan city has a lot of diversity in terms of geomorphology, and this problem has caused its different parts to have different potentials for creating military objectives. Considering the importance of creating security in the border strip, it is necessary to pay attention to the geomorphological capabilities of this city in order to create security in the region. In this research, based on the geomorphological capabilities of Marivan city, vulnerable areas were identified against the enemy's influence, as well as areas susceptible to the construction of military bases and observation centers.
 

According to the results, due to the geomorphological situation of Marivan city, parts of this city lack sufficient visibility and are far from the monitoring and control of military bases, and this problem has caused these areas, which mainly include the southwestern and southern regions. Is a city, have a high vulnerability potential. Also, the results of this research have shown that parts of Marivan city, which mostly correspond to the central areas of the city, have a high potential for building military bases and observation centers. Due to high altitude, low slope, western directions, wide field of view, proximity to main roads and being far from military bases, these areas have high potential for the desired goals. The total results of this research have shown that in locating military bases in Marivan city, geomorphological factors have not been given much attention and it is necessary to establish security in this region, military bases and observation centers. He built a new building in accordance with the geomorphological strength of the region.

Cultural and social development and valuable activities in a society will not be possible without security. In many areas, there may be police management, but it does not make people feel safe. The effect of the cultural and social functions of the police in the police management of coastal areas, the effective factors for tourists' well-being, and the determination of the effect of these factors on the sense of security are the problems of the present research, which aims to determine the impact of the cultural and social functions of the police in the police management and the security of tourists in the coastal areas of Mazandaran province.

Design/methodology/approach:

 In terms of its nature, the current research is among descriptive and non-experimental field and survey research, and its statistical sample consisted of 400 police commanders and managers of the province. Using fuzzy analysis and Excel software, the researcher investigated the cultural and social indicators of police that are effective in security, and then, using SPSS software, the research hypotheses were tested.

The findings of the hypothesis test show that the police operational capability index, the police professional behavior index, and the police social activities index are effective for tourists in the coastal areas of the province.

The results show that police management and security in coastal areas are not only through the operational capability of the police, but also the professional behavior and social activities of the police are effective in creating security.

Originality/value: 

This research has presented a model in line with the implementation of police management strategies and increasing the sense of security in the beaches and paying attention to the supervision and demands of the natives and tourists, in which the government interventions are minimal.

In this research, the analysis of influential components in vulnerable urban spaces at the neighborhood level within one municipality of Tabriz is conducted. Urban spaces are pivotal for citizens' life and activity, aiming to provide safe, healthy, stable, and attractive environments that cater to diverse societal needs based on individual characteristics, age, social groups, and gender. The study utilized the T-test to analyze components, dimensions, and effective areas in vulnerable spaces, categorizing twelve investigated components into three groups and assessing their impact separately. Additionally, one-way variance analysis was employed to compare 13 neighborhoods in Tabriz city, with subsequent ranking using the Vicor model. Results highlight that physical-environmental components exerted the most significant impact on the formation of vulnerable spaces, revealing notable differences among localities concerning missing spaces, corners, inadequate lighting, and specific alley and street configurations like L-shaped and U-shaped layouts, underpasses, and bridges.

The position of the Tigris and Euphrates rivers is in the least compatible with national borders or with the political and strategic considerations of regional countries. The sources of the Tigris and Euphrates rivers are located in Turkey, and Turkish authorities believe they own the resources. A project called "Gap" or "Anatolian" in the framework of the construction of more than 22 dams and 19 hydroelectric projects and development of the agricultural system in the Tigris and Euphrates watersheds has been on the Turkish governmentchr('39')s agenda by 2023, reflecting the security threat. The environmental and water security of the downstream countries (Iraq, Syria and Iran) have been demonstrated. The present study is based on the assumption of reflecting the Hydropolitic relations of the Tigris and Euphrates basin (based on Gap Project) with the viewpoint of continuing climate change and changing rainfall patterns and increasing water use in downstream countries using library resources. In the form of a threat to the security of the southwestern areas of Iran, it will intensify. The results showed that the consequences of the Hydropolitic approach of the Tigris and Euphrates countries, especially Turkey, besides threatening environmental security, affect other aspects of security in the economic, social and political spheres in the southwest of the country.

Methodology This study is quantitatively, and its purpose is practical, in terms of data collection is descriptive - survey. For data analysis software was then used SPSS as the original software, and the software LISERL as a helper application for factor analysis (exploratory) were used. The statistical population of this research includes Professors related to the fields of economics, management, political geography and border security are the universities of Ilam province, economic activists and border cooperatives of Mehran and Dehloran cities, and executive managers of Ilam province.ResultsIn this study, 25 obstacles were identified regarding the underdevelopment of production cooperatives at the borders. which after using factor analysis, the Kaiser criterion was used to determine the number of factors. Based on this criterion, 4 factors(Individual, social and cultural factors, administrative and supportive factors, financial and economic factors, security and political factors) with a specific value of more than 1 were identified and identified as extractable factors. According to the statistical indicators using the main factor analysis method, these 4 factors could explain a total of %92.672 of the total variance of the variables.Conclusion The results showed that Individual, social and cultural factors with a total factor load of 6.055, administrative and supportive factors with a total factor load of 4.711, financial and economic factors with a total factor load of 2.928 and security and political factors with a total factor load of 1.407, Respectively, the most important obstacles are the development of production cooperatives at the borders.

The development and progress of a society depends on maintaining security and the feeling resulting from it. Border security is the foundation of the country's national security. The presence of people in the border areas requires their feeling of security. A feeling of insecurity is one of the most significant factors threatening the presence of people in the border areas. The feeling of security is the base of human survival in any place. In this regard, the present study uses descriptive and analytical methods and library studies to evaluate and explain the sense of life in the Arvand Rud coastal border. In this study, the life dimension of a sense of security was considered a dependent variable, and individual characteristics, life on the coast, tribal violence, the concern of natives leaving Iranian waters, the insecurity of the neighboring country, and insecurity in non-Iranian waters are considered independent variables. According to the Cochran formula, the sample size of the study was considered to be 315 people from 16 villages and two urban centers of the Arvand Rud coast. All the variables were extracted as maps after analyzing them in SPSS software and with the help of GIS. To use the results of the t-test, the results of Levene’s test are used first. The results of the test indicated that the error rate was 0.61. In other words, the accuracy rate of the test is 39 percent, which is more than the acceptable level. Thus, there is a difference between the variances. The results of the t-test, assuming equality of variances, indicate that this test is significant at a confidence level above 95%. Since the sense of life security is 2.5 in rural areas and 2.7 in urban areas, it can be stated that the sense of life security in urban areas is in a better state than in rural areas. If we separate the villages from the cities, the feeling of life security is better in the southern villages of the study area. Also, the feeling of life security was more in the villages except for the lack of feeling of security when the sailors were leaving Iranian waters.

The process of regeneration of Derelict Fabric is done to revitalize, modernize, and enhance the quality of the environment to achieve a desirable future and to address future issues of urbanization and urban life in order to have a viable city and neighborhood. Sustainable city, in a simple definition, is a city that has the components of security, dynamism and vitality and also provides safe and attractive housing, education, health and culture for citizens. Among the different qualities expressed by different theorists in terms of spaces responsive to user needs can be security, dynamics and vitality. The purpose of this research was to investigate the impact of security, safety and vitality components on the regeneration process of worn-out neighborhoods in the White Soil neighborhood of Chahar-e-Tehran. The data were collected using a questionnaire which was used to assess its validity by Cronbach's alpha method, whose reliability was confirmed by 0.831. To determine the sample size, Cochran formula was used and 321 questionnaires were calculated and distributed among the residents of 69458 white soil neighborhoods. Then, data were extracted and categorized. In the Findings section, according to the tables, the variables related to the indicators of effective safety and vitality have the highest to moderate acceptance. In spite of the exhaustion of neighborhood texture, security and vitality can be seen in the neighborhood. In other words, it can be concluded that security, dynamism and vitality will advance the goals of regeneration and enhance the process of regeneration of worn-out neighborhoods.  

 The feeling of belonging to a place in ancient tissues has always been the most important factor for its durability and stability, both physically and functionally, and semantically and memory-wise. Spatial affiliation refers to a cognitive relationship with a particular environment or space, and in fact attachment to a place is a symbolic relationship created by individuals to a place that gives common emotional, emotional and cultural meanings to a particular space. (Altman & Low, 1992) A spatial place is an identity-building, relative, and historical that never completely disappears. Residential neighborhoods are one of the oldest urban heritage that the sense of belonging of residents makes it sustainable. Users are stated, we can refer to the quality components of the urban environment (sense of belonging to a place, security, dynamism and vitality). Among the different definitions of these environmental qualities, it is emphasized that these components indicate the dynamism and vibrancy of the space, and as a result, that space will be suitable for the presence and activity of users. Therefore, these environmental qualities seem to increase the sense of environmental belonging, and through this, among the diverse range of qualities of urban spaces, the mentioned components are undoubtedly one of the influential qualities in creating space (Lynch. 1997.307) )Today, urban and citizenship issues have become the most important issues affecting the quantitative and qualitative dimensions of human life. Before this period, the city was important in its general sense, but in the contemporary period, this importance has been perceived by a wider range of people. Therefore, addressing the new theories of the city, each with the aim of solving urban problems, improving the quality and quantity of life of citizens in cities, improving the quality of the city environment, city management, advancing the city to become more desirable, etc. It is more important than ever. Viability, which ensures sense of belonging to a place, security, dynamism and vitality, is divided into three interrelated dimensions: the economy, society and the environment. If the function of any of these three dimensions is disrupted, human settlements can quickly deteriorate, resulting in declining population, poverty, social conflict, and rising health and environmental issues. (Khorasani, 2011:35) In general, a livable city includes a diverse set of characteristics: sense of belonging to a place, security, dynamism, vitality and participation. If urban areas do not have viability factors, the only motivation for new residents is to have a shelter, and despite many cultural differences, they live in this part of the city due to low housing prices. Therefore, due to the feeling of separation and alienation from neighbors and residents, it suffers from confusion and confusion, and consequently, social, economic and cultural instability occurs in these neighborhoods.

The research method of this article is applied in terms of purpose and descriptive-analytical in terms of nature and method. Its purpose is to evaluate the Sense of belonging to a place, security, dynamism and vitality situation in Khak-e-Sefid neighborhood of Tehran's Chahar district based on the explained indicators. The statistical population studied in this study are residents of Khak-e-Sefid neighborhood, located in the sixth district of Tehran's four municipalities. According to the latest census in 2016, Khak-e-Sefid or Golshan neighborhood has a population of 69,458 people. Thus, the Sense of belonging to a place of the neighborhood is assessed using field data collection (distribution of a questionnaire among the residents of the studied neighborhood). Cochran's formula was used to determine the sample size. 321 questionnaires were calculated for the population of 69458 people in Khak-e-Sefid neighborhood and distributed among the residents. To evaluate the validity of the questionnaire, the views of experts, experts and city managers were used. In this study, Cronbach's alpha method was used to measure the reliability of the measurement tool. Cronbach's alpha obtained in this study was 0.831, which indicates that the reliability coefficient is at an acceptable level. Finally, after analyzing the information through SPSS method, finally based on the obtained results, recommendations to improve the performance of neighborhood spaces in order to improve its vitality and sense of belonging to a place and the effect of security, dynamism and vitality on the regeneration of Khak-e-Sefid neighborhood with emphasis on using The model of sustainable neighborhood development will be presented.

To achieve the purpose of the research and answer the main question of the research on whether the components of sense of belonging to a place, security, dynamism and compatibility affect the regeneration of problematic tissues, the variables and indicators that were in the form of a questionnaire were provided to the statistical community. The respondents are residents of Khak-e-Sefid neighborhood of Chahar city of Tehran. Due to the high population of the neighborhood, the sampling method and determining the sample size were used to study the area through the Cochran's formula and 321 questionnaires were distributed among residents. Considering that the components of sense of belonging to a place, security, dynamism and adaptation in each city, region and neighborhood are affected by the three dimensions of social, economic and environmental cities that constitute the indicators of urban livability, the response of neighborhood residents to each of the variables The trivia of livability is given in tables in the text of the article. 

In answer to the research question, ie the components of sense of belonging to a place security, dynamism and compatibility affect the regeneration of problematic tissues, it should be said that what is effective in the sense of belonging to a place, security, dynamism and vitality of an urban neighborhood are things that can result in referring to urban space as a destination. In other words, coming to space and staying in it can make the space safe and lively and lead to the accumulation of memory. According to the results obtained from the tables and analysis of the percentage of frequency variables of livability dimensions, each of which has a high impact on creating sense of belonging to a place, security, dynamism and vitality of the neighborhood environment. It is observed that the variables related to the indicators affecting safety and well-being, especially the variables related to the indicators of "recreation and leisure", "cohesion and belonging", "individual and social security" and "participation and solidarity" have the highest to moderate acceptance. It can be concluded that the more livable the neighborhoods and residential areas of cities and of course have the components of sense of belonging to a place, security, dynamism and vitality, the goals and results of urban regeneration and regeneration projects are achieved more quickly and the neighborhoods and residential areas of their past originality are comfortable They will gain more principles.

There are several concepts in order to achieve sustainable urban development. One of the most important of these elements, sometimes referred to as the fourth pillar of sustainable development, is a sense of social security, due to the existence of an acceptable level of it among citizens, Mental and physical health, sense of identity, participation, happiness, active presence of citizens in different urban spaces, etc. can be expected and conversely. The purpose of the present quantitative and applied research, where documentary data and field studies have been used to collect information, Examining the state of social security and identifying key social and economic factors affecting it Which has been done as a case study in Yasuj. The statistical population of the study consists of all heads of households of which 380 are considered as a statistical sample. Descriptive and inferential statistics in the form of SPSS software were used to analyze the collected data.The results showed that the calculated average for life, financial, value and cultural, family, moral, occupational and economic security status, As the main dimensions of the feeling of social security, respectively with values of 2.87, 2.33, 2.52, 2.39, 2.8 and 1.98, was significantly lower than the baseline (number 3) And General condition of feeling of social security with an average of 2.48, Due to the key dimensions of its component, it is significantly lower than average. The results showed the final and confirmed model of determinants of social security using multivariate regression Among the seven variables that had a statistically significant relationship with the dependent variable of the research, the effect of four variables was significant and in total they were able to explain 51.8% of the variance of the dependent variable. The key variables of identification in order of importance are: Socio-economic status, police performance, social capital and social anomalies (with negative effect) The standardized regression effect coefficients of each of them are: 0.347, 0.228, 0.195 and -0.175, respectively.

Housing is one of the main human needs, which is known as the basic biological need for humans. Sustainable housing refers to a wide range of opportunities to improve economic development, environmental protection, quality of life and social equality. It requires a detailed and comprehensive look to be able to address the various dimensions of security, in fact, as the discovery of the hidden connections between those dimensions at different levels. Among the effective factors in the security of every city are urban spaces and places, therefore, due to the increase of social anomalies in today's societies, it is necessary to examine social security and factors affecting it. Urban areas are a place to live and to know the sense of belonging to the place of its residents is one of the necessities of maintaining the quantity and quality of this population. For this reason, social security is considered as one of the development indicators, based on which the level of development of urban housing and even countries is evaluated. Therefore, in order to solve the problems of feeling insecure in urban housing and achieving sustainable urban development, examining the components of well-being, The comfort and safety of citizens, which is one of the basic goals of urban planning. Urban insecurity in different fields includes that part of anomalies that have emerged as a result of the emergence of urbanization and the social problems caused by them and cause structural and functional damage in the urban society at different levels. Results The preliminary data from the studied area shows that the building materials used in the construction are often of very low quality and due to the lack of attention to the executive instructions considering that the city of Nowshahr is exposed to many natural disasters such as floods and especially earthquakes. Housing is one of the important indicators to maintain the safety of the residents of the study area. For the reasons that were mentioned, it seems necessary to examine the issue of housing sustainability due to its importance and impact on life-financial security, etc. In other words, the need to live in a safe environment in the study area is very important, which requires adaptation and interaction with the environment for the well-being of citizens, both mentally and objectively, according to the above-mentioned contents of this research. is to examine the set of factors that cause the stability of housing in social security in the study area .

The current research is applied in terms of type and descriptive-analytical in terms of method. Two library and field methods have been used to collect the required information. The statistical population of the research is Nowshahr city, which was determined based on Cochran's formula with an error of 0.05% of 384 questionnaires. A simple random method was used to distribute the questionnaire. It has been used to propose indicators using internal and external studies. The validity of the questionnaire items has been confirmed by the opinion of a number of academic researchers and its reliability has been calculated using Cronbach's alpha test to the extent of 0.75. In the analysis of the data obtained from the questionnaire, structural equations of laser (SEM) have been used. In fact, structural equation model is the Persian translation of Structural Equation Model, which is also called SEM for short. This method is a special causal structure between a set of latent variables and observable variables. Using the structural equation modeling method, the relationships between hidden variables can be investigated, as well as the measurement items of each hidden variable with the relevant variable. Lisrel software is used to perform the calculations of this method. 

The findings of the research show that among the 384 respondents, 15% are in the age group of 30-40 and 30% are married, gender is 79%, place of birth is 78%, and employment is 70.24% of the total respondents in this research, the largest age range is related to the age group of 33 up to 43 years old with 32.45% and the lowest age group is 20 to 35 years old with 0.8%; Also, 17.5% were in the age group of 35 to 40 years old, 24.3% were between 45 to 55 years old, and 19.9% were over 65 years old. One of the presuppositions of using structural equation modeling using Lisrel software is the normality of the data. Therefore, in this research, the Kolmogorov-Smirnov test was used to check the normality of the research data. In conducting factor analysis, one must first ensure the appropriateness of the desired data for analysis (sample size and relationship between variables). For this purpose, KMO indices and Bartlett's test are used to verify the adequacy of the sample size. If the value of the KMO index is less than 0.6, the results of the factor analysis are not suitable for the data in question. 

The purpose of this research was to study the role of sustainable urban housing in social security, and the results showed the positive impact of dimensions on household social security. The results of the descriptive findings show that 10 important factors play a role in the extreme fluctuations in housing prices in Nowshahr, which include things such as: lack of access to cheap housing for citizens, fluctuations in housing prices and household savings, construction fluctuations Housing, the role-creation of municipalities and the increase in housing prices, the role of builders in housing market fluctuations, the role of intermediaries and sellers in the housing market, income inequality and high housing prices, land prices and their effect on housing price fluctuations, the presence of brokers in the housing market. and the increase in housing prices and the lack of firm rules in determining housing prices and the prevalence of speculation .

Physical security and access to public services are considered to be one of the most important features of a healthy residential neighborhood and lead to the promotion of safety and a sense of peace and vitality in citizens. Physical security tends to protect people's life and property and fulfills their daily needs by providing access to public services. The purpose of this research is to measure the impact of physical security and access to public services on improving the quality of living of citizens. The research method is descriptive-analytical and the questionnaire tool was used to analyze the information and the sample studied in the research is Region 4 of Urmia city. In this research, by using Pearson's correlation coefficient, which was obtained for all the variables of physical security indicators and access to public services in relation to positive and meaningful residential quality, it can be concluded that by improving housing security indicators, It is possible to help improve the living quality of citizens, although this relationship is not very strong. Based on the obtained results, the level of public satisfaction with the physical security index among the residents of region 4 was low and equal to 2.23. Meanwhile, satisfaction with the life of the residential unit and the quality of the main roads are the lowest with 2.14 and 1.27 respectively. The level of satisfaction with the criterion of access to urban services due to the presence of activity nodes in this area is higher than the average and is equal to 4.04.

In recent decades, with the increase in population and the change of different generations and cultures in metropolises and the change of lifestyle, security has become a very important challenge. Security is related to satisfaction, comfort of citizens and desirability of life in the form of sustainable human development and an indicator for quality of life. The feeling of insecurity threatens the presence of people in the urban space, disrupts vitality and health, and reduces public participation. Based on this, the current research has been carried out with the aim of analyzing the security of metropolises with an emphasis on the management of informal settlements in Tehran and determining the factors affecting the insecurity of the capital.

This research is applied in terms of purpose, descriptive and survey in nature and analytical in nature. Using the simple random sampling method and based on Cochran's formula, the sample size is estimated to be 383 people, and to identify the security components and variables, a questionnaire tool was used in the form of 5 structural, managerial, content, legal and socio-economic components. has been studied.

The findings indicate that, in the first factor, the integrated attitude in security management and the lack of coalition between security experts, in the second factor, the traditionality of security planning and the multiplicity of political attitudes and views in the informal settlements of the capital, the third factor , the prevalence of the law-abiding culture, cultural differences and population density, the fourth factor, lack of security and safety in night travel, the fifth factor, the weakness of approved rules, plans and programs, and the sixth factor, the low transparency of laws that have the greatest impact on harm Acceptance of informal settlements are the capital.

Weakness of regulations, approved plans and programs and lack of budget and security equipment are among the variables that affect the security of informal settlements in the capital, and in this context it should be said that managerial, legal and structural vulnerability causes insecurity, lawlessness, cultural differences and lack of security. and the safety of informal settlements in Tehran metropolis.

The purpose of the article is to investigate the impact of the spatial structure of the administrative buildings of Karaj city on the internal and external scale on the productivity of employees and compare it with the impact of physical factors stated in the existing theories.

The research is applied in terms of its purpose and descriptive in terms of its method. The main variables were extracted according to Haines model and classified using ANOVA test. Data collection has been done by questionnaire. The analysis of the space syntax of the buildings including three variables "interconnection", "depth" and "connectivity" was carried out in three levels "macro", "immediate" and "internal" in the UCL.Depthmap.10 software environment. In the inferential analysis, confirmatory factor analysis (CFA) and path analysis in the LISREL.10.2 software environment.

Physical factors including "temperature and ventilation", "noise and acoustics", "light", "dimensions" and "ergonomics" have the greatest impact on self-reported productivity in high-rise office building employees. Among other factors, the space syntax has an effect on employee productivity at three levels: macro (city scale), immediate area (surrounding area) and internal (architectural plan). The impact of the space syntax is lower than the physical factors and it is not equal under the variables of "integration", "depth" and "connectivity". Among the variables of space syntax, "connectivity" has no relation with employee productivity. The two variables of "connectivity" and "depth" also have different effects at the urban level and directly.

In work environments, physical factors are effective in the productivity of employees, regardless of the work pattern. The internal space syntax is related to the interaction and concentration of employees, and this issue has a different effect depending on the working model. At the urban scale, "integration" has a direct and weak relationship with productivity.

Cities are complex spatial-geographical phenomena that need to be studied and providing security as one of the most basic human needs of urban societies is considered. Security and threat studies have been developed and changed simultaneously with the transformation of societies and the concepts of security, power and threat. It seems necessary to identify the threats of the urban area, especially with the expansion of the use of new tools and technologies because new threats are also associated with them. The purpose of this research is to analyze the role of technology- based threats to the security of Tehran city. The approach of this research is mixed, and the data collection method is library and documentary. The results of the analysis of questionnaires by SPSS software led to the prioritization of technology-based components in urban security. The findings of this research show that emerging threats are based on technology, and some of them include Internet of Things, artificial intelligence (weapons), e-commerce threats (electronic skimming, ransom ware, and malicious bots), bioterrorism, and cyber threats. (Crypto-currencies) and micro air vehicle, the share of artificial intelligence (weapons based on artificial intelligence) has the largest share. Also, the mentioned components will have the greatest impact on economic security.

This study seeks to investigate the security-defense status in the coastal area of southern Iran from the west of Hormozgan province to the east of Sistan and Baluchestan province (Chabahar and Konarak cities). The Descriptive-analytical research method has been used in this research. The required data have been gathered from land management documents and the Statistical Center of Iran. 53 indicators have been used in different natural, environmental, cultural, social, economic, and residential dimensions to measure the security-defense status of the studied area. The findings of the research indicate that the security-defense plan requires an integrated and systematic look at the natural and human threats inside and outside the borders. The modeling of the affecting defense-security elements in the studied area showed that the roots of sustainable security and powerful defense lie in geographical and human characteristics; Also, the study of the geographical and socio-economic characteristics of the southern coasts of Hormozgan and Sistan and Baluchistan showed that the lack of stable security and defense of the land was accompanied by the lack of balance in development and the backwardness of some of the desired criteria and indicators.

By analyzing the characteristics of environmental, physical and human factors to facilitate the commission of crime and by creating and strengthening order and security and physical and policing safety, it is possible to prevent the occurrence of many anomalies, especially in parks and green spaces, or make it as difficult as possible to commit it. On the one hand, urban parks are mostly a platform for social interaction and leisure time, but on the other hand, due to the presence of a large population, density of vegetation, low visibility, limited resources, and lighting at night, there is a great opportunity for crimes to occur secretly. The indicators used in this research were analyzed and analyzed with sample t-tech statistical tests, step-by-step regression, in the form of spss software. The results showed that each of the security indicators actually had an average effect on the security of citizens and this effect has intensity in different dimensions. And it is weakness; And this calculated value is lower than the standard, we conclude that the security situation of parks and green spaces in the 5th district of Shiraz is not acceptable. Among the indicators affecting the security of parks and green spaces in the 5th region of Shiraz (linguistic security, physical security, visual security, sense of security), the visual security index with a beta coefficient of 462.0 has the greatest impact on citizens' security, and the linguistic security index with a beta coefficient of 116.0 is the least.

Transformations such as globalization, the contiguity of geographical spaces, as well as developments in the field of military technologies have transformed the issue of defense as the main factor for the survival of countries. Because the transformation from hard to soft war and then the smart war in recent decades has changed the approaches to defense. These transformations have led to the development of discussions about defense purposes. Meanwhile, Middle East countries have a prominent position and importance in terms of defense due to their special conditions. This article has tried to investigate the basic dimensions affecting the defense of foreign countries with descriptive and analytical methods, using library and field findings and Smart-PLS software. The results of the current research show that the effective components in the current research include 130 items that are placed in the form of 15 dimensions. The importance of these dimensions in defense of the Middle East countries is, respectively, geopolitical dimension with a 0.43 score, military dimension with a 0.41 score, economic dimension with a 0.41 score, political dimension with a 0.39 score, hydrology dimension with a 0.34 score, security dimension with a 0.32 score, social dimension with a 0.29 score, demographic dimension with a 0.28 score, cultural dimension with a 0.26 score, scientific-health dimension with a 0.25 score, geomorphological dimension with a 0.25 score, mathematical dimension with a 0.2 score, climatic dimension with a 0.2 score, biological dimension with a 0.2 score and soil dimension with a 0.18 score.

The creation and expansion of rural settlements is influenced by various factors, these factors are divided into two categories of natural and human factors, whose impact on the construction and pattern of these settlements is undeniable. Changes in the pattern and architectural style of rural housing have occurred in many different ways. The present study has examined all the factors affecting the rural housing model in Khalkhal county. The main purpose of this study is to investigate the role of natural and human factors in the rural housing model and determine the degree of correlation between these factors and rural housing. The research method in this study is applied in terms of purpose and descriptive -analytical in terms of method. In the first part, the results of studies show that natural factors have played a very effective role in the pattern of rural housing in this region. Therefore, the role of factors such as water resources, climate and, most importantly, the specific topography of the region have played a more colorful role than other environmental factors. In the second part, the effects of human factors in rural areas on the rural housing model are examined. The statistical population of the study is 5 villages of Khalkhal city with a population of 10,650 people in the form of 1940 households. The sample size is 320 rural households, which were interviewed by random sampling. For data analysis, Pearson and Spearman and multivariate regression methods were used using SPSS software. The results show that there is a significant and relatively strong relationship with a coefficient of 0.675 between human factors and the rural housing model in the study area, so that the socio -cultural index explains about 58.8% of the housing model .
