Abstract
The increased use of thermal power plants has led to the spread of greenhouse gases in the air and has caused psychological problems for humans. Accordingly, the present study was conducted to measure the pollutants released by Sahand Bonab thermal power plant and to investigate the effects of this pollution on the psychological and psychological pressure of rural residents. The GWP100 method was used to measure the pollutants of the power plant and to measure the mental and emotional pressures of the citizens, a questionnaire was used to assess the psychological stress of Markham. The statistical population of this study is 10254 people over 15 years of age in 7 villages located in the greenhouse of the power plant. Using formulas and simple random sampling, 375 subjects were selected as sample size. The results showed that the most pollutants released are CO2 and NOx, which is 4.17 times the warm seasons in the seasons. Also, analysis of the results by using a Pearson test showed that six variables including neurological and disturbing variables p= 0.272, stress and psychological stress p= 0.325, feeling of energy decrease, p= 0.287, feeling of despair and disappointment in life p = 0.142, feeling Depression in life of p= 0.211 and change in behavior patterns in everyday life p= 0.269 had the most effect on air pollution. Also, mental and psychological stress in nearby villages was higher than in remote villages, more women than young men than older men and elderly people. The results of multivariate regression and path analysis showed that in general, the air pollution caused by the power plant has the ability to explain R2 = 37.42 percent of the changes related to the psychological and psychological pressure of the villagers. Finally, it can be said that thermal power plants have negative mental and psychological effects according to type of activity, type of age and gender of the villagers, which should be considered in the studies of the construction of power plants.

Abstract
In today's world, the process of globalization and communication and information innovations has brought the "cities" into an actor of national and global competition. No urban point in the world can rely on maintaining its traditional role in the urban hierarchy, as other urban areas compete in a network structure with other cities in order to enhance their position on the network and overcome other competitors. In contemporary cities, forces, activists, and urban actors face a different role in their political, economic, social, and cultural domains, with a view to their modern and highly sensitive interests, and therefore competition between the positive and the negative ones It has emerged or is underway. Given the importance of this, political geographers and geopolitics are studying the important process, which is in fact the "urban geopolitics", created in the wake of urban competition, and with the growing competition of urban action-makers and forwards ahead. , Pay. The present paper uses a descriptive-analytical method to make it clear that urban geopolitics, on the one hand, includes a set of common rivalries, ideas and perceptions of political factions, religious denominations, or other social centers that social groups It brings to the fore and creates a worldview for them. On the other hand, the concept of this survey shows how these perceptions, the field of decision-making by citizens, and the occurrence of competition, change, and sometimes even protests in urban environments. It then changes with inspiration from geopolitical conditions. Hence, a kind of geopolitical measure on a city scale has made cities important actors in diverse geographic areas. The results of this research show that the multi-dimensional phenomenon of the city is studied by political geographers and geopolitics, with emphasis on the pivotal elements of space, politics, power and competition.

Abstract
The migration of young people and the aging of rural communities, for reasons such as poverty and unemployment, will create a lot of need for identifying new approaches to the survival of rural communities. Small business entrepreneurship has an important role in reducing poverty and, ultimately, rural development. However, this kind of entrepreneurship faces many challenges in terms of environmental, economic and ... The purpose of this research is to examine the challenges of entrepreneurship in improving entrepreneurship, creating employment and sustainable income through setting up small businesses. The present research is aimed at applying the field of observation and control, and in terms of the nature and method of descriptive-analytical. The statistical population of the study consisted of rural households living in Bijar. According to the census of 1395, the population of this city was 89,162 persons, which according to the distribution of 44% of the rural population and 56% of the city. There are also 283 rural villages in the seaside district, among which 12 villages have entrepreneurship and 244 of them are households using the modified Cochran formula. Data gathering method was library and field questionnaire (questionnaire). In this questionnaire, individuals were asked to identify the importance of each of the identified challenges in rural small business based on the options of this spectrum (high, high, medium, low, and very low) based on the Likert spectrum. Structural Equation Modeling (Factor Analysis) has been used for analyzing data in Amos software. The results of the research show that all challenges in the entrepreneurship of small businesses have been affected, but economic factors with factor load of 0.91 have the highest impact among existing challenges and the individual and social challenges with factor load are 0.23 and 0.28, respectively. The least load has been the factor.

Abstract
The national strength of algebraic aggregation is a large number of positive and negative factors that are composed of numerous sources and resources. One of the important sources of national power in the world today and in the post-Cold War period is economic power, which is itself the bedrock of other superstructures, such as political, military, and so on. This research uses descriptive-analytical method and using library resources and field research to answer this question. What are the most important variables and indicators that shape economic power of countries? The findings of the research by examining library documents show that the four main components of economic power including infrastructure, production exchange, production level and financial resources can affect economic power. Meanwhile, 61 variables related to quadruple components were identified. Then, by using the Likert spectrum questionnaire, internal knowledge was measured to measure the importance of each of these variables. Accordingly, economic infrastructure, high-tech exports, food imports and international currency reserves were of high importance. On the other hand, variables such as the share of the poor in the consumption of national income, economic competition, foreign ownership, and commercial costs of violent crimes were of minor importance. Finally, it can be argued that countries have an obligation to take into account the factors and variables in the economic dimension to achieve their national interests and interests.

Abstract
There are several limiting factors to the development of cities. These factors lead cities to develop in certain directions. Air pollution as a major problem of metropolises can itself be considered as a limiting factor of urban development by urban decision makers. 4 relatively large power plants are operating in Mashhad. There are currently two power plants in the east of the city and two in the west of Mashhad. Most of the fuel in these power plants is gasoline and natural gas. Modeling the air pollutant emissions of these power plants and identifying the pattern of pollutant emissions across the city can play a key role in the quality of life and health of approximately 3.5 million Mashhad residents. The outputs of this model can also be used as an effective parameter in estimating the urban development model. In this study, the emission of NOX, CO and 10PM pollutants was modeled and evaluated using AERMOD software in Mashhad. Using Arc GIS software, the population affected by these air pollutants was determined by one year solar time, the concentration of pollutants in different areas of the city and the area affected by the pollution concentration range was determined.

Abstract
Following the victory of the Islamic Revolution, a new perspective on science and technology emerged in Iran. This scientific discourse was profoundly shaped by the principles of the Islamic Revolution and Islamic ideology, leading to the establishment of new values and objectives for the advancement of science and technology. In the post-revolutionary era, as policymakers recognized science and technology as pivotal drivers of societal progress and excellence, they devised scientific policies and strategies aimed at achieving revolutionary and Islamic ideals. This evolving attitude toward science and technology significantly influenced Iran’s scientific and technological development during this period. Given that the Islamic Republic of Iran has assumed a leading role in scientific leadership within the region since 1979, its contributions to the development of scientific capabilities under successive post-revolution governments are noteworthy. To explore this, a descriptive-analytical approach was employed, utilizing reliable data from both domestic and international sources. The research findings indicate that the prevailing discourse in different governmental periods included a focus on industrialization through import substitution and capital resource allocation (1981–1989), modernization and institutional development with an emphasis on advanced technologies (1989–1997), the promotion of advanced technologies, innovation, export expansion, and social justice centered on knowledge-based industries (1997–2005), the transition toward knowledge-based innovation in the economy (2005–2013), and the enhancement of international cooperation with an emphasis on identity and rationality in policy formulation and implementation (2013–2021). The results demonstrate that, in each phase, measures such as the expansion of higher education and scientific research, the establishment of universities and research centers, and the creation of domestic and international scientific networks were implemented in alignment with the dominant discourse.

Abstract
As China's economic, technological, and military power continues to rise, the United States has grown increasingly concerned about Beijing's expanding influence. Washington perceives China's regional ascendancy as a challenge to its hegemonic ambitions. China's growing military capabilities and political influence in East Asia have sparked concern and suspicion among some of its neighbors and the United States. In response, the U.S. has maintained an active presence in the region, citing reasons such as countering China's rise and supporting freedom of navigation. Washington's efforts to challenge China's maritime sovereignty reflect its broader concerns about China's rise and its determination to maintain hegemony in the Asia-Pacific region. This has led the United States to attempt to create a strategic encirclement against China, aiming to contain its regional influence and prevent a shift in the balance of power in East Asia that could disadvantage Washington. The research question addressed in this study is: What strategy does the United States employ to contain China's power in the South China Sea? The proposed hypothesis is that, given China's economic growth and the expansion of its maritime power are perceived as strategic threats to the region and the United States, Washington seeks to prevent China from becoming a regional hegemon in East Asia. By countering China's rise, the U.S. aims to shape the balance of power in favor of itself and its regional allies, thereby securing its goals and interests in the region. This study employs a descriptive-analytical method to examine how the U.S. strategy of containing China's power and isolating it regionally contributes to maintaining the balance of power in East Asia, while advancing the influence and interests of the United States and its allies.

Abstract
Villagers' self-organization, as a collaborative process, plays a fundamental role in promoting sustainable livelihoods in rural areas. This study was carried out to identify the driving forces affecting the self-organization of villagers and to improve sustainable rural livelihoods in Ashtian County, Iran. Utilizing a qualitative research design with an analytical-exploratory approach, data were gathered through semi-structured questionnaires and in-depth interviews with 30 subject matter experts. The collected qualitative data were analyzed using the Delphi method and MicMac software to identify underlying relationships and patterns among concepts. The findings indicate that the distribution of factors and variables influencing the improvement of sustainable rural livelihoods in the study area is characterized by instability. Additionally, among the 24 primary influential factors, 10 critical drivers emerged as pivotal to advancing villagers' self-organization and promoting long-term sustainability in rural livelihoods. These drivers include innovation and creativity of villagers in agricultural and non-agricultural activities, skills and experience in group activities, and the establishment of local organizations as individual factors; increasing the spirit of entrepreneurship, launching, and promoting new local businesses as psychological factors; increasing participation, cooperation, and a sense of responsibility in agricultural and non-agricultural activities as social factors; empowering villagers by increasing their awareness, social and economic skills, and leveraging new IT and ICT technologies for structural empowerment in the direction of self-organization as education and empowerment factors; access to diverse and reliable financial resources for agricultural and non-agricultural activities as economic factors; delegating authority to villagers in line with local planning and decentralization as planning and management factors; and finally, supporting the creation and development of local businesses, diversifying agricultural and non-agricultural activities, and increasing investment in innovative businesses as socio-economic support factors. These drivers collectively contribute to advancing villagers' self-organization and enhancing sustainable rural livelihoods.
