Introduction: The importance of climate and its impact on human life is not hidden from anyone. The expansion of urbanization and development of cities along with the rapid growth of population and development of industrial activities has greatly reduced the thermal comfort in residential spaces, the consequences of which in the short term in the form of diseases and illnesses to city dwellers and in the long run as a factor in intensifying climate change. Its environmental effects, including the change of favorable months in terms of comfort climate, play a role. Meanwhile, the high costs of establishing comfort in residential spaces by mechanical devices and especially their maintenance, as well as its consequences in environmental degradation, has increased the importance of urban climate research. Therefore, the view of this study is to investigate the effect of climate on physiological comfort and convenience of human beings in closed spaces under the influence of two elements of temperature and humidity.Research Aim: The purpose of this study is to analyze and evaluate the effect of climate on physiological comfort and convenience of humans in closed spaces under the influence of two elements of temperature and humidity.Methodology: The research is an applied type that has been done by descriptive-analytical method. The data used include average minimum, maximum and daily temperature, relative humidity, vapor pressure and dew point temperature in the statistical period of 40 years (1979-1979). For data analysis, indices of discomfort, temperature-humidity, sultry intensity and AIA standard were used.Studied Areas: The study area in this research is Rasht city in Guilan province.Results: The research findings show that heat discomfort reaches its maximum in July and August and also August has the highest amount of sultry.Conclusion: The results of the study indicate the greater effect of temperature element on the establishment of thermal comfort because despite the low relative humidity in the four months of June, July, August and September compared to other months, the degree of sultry and lack of thermal comfort in this month It reaches its maximum, which in addition to creating shade, also needs natural air ventilation to establish thermal comfort.

AbstractThe role of small towns in development of rural areas is known to everyone. Urban functions manifest in areas such as services, exchange of factors of production and complementary role in rural development. In this regard, planners pay special attention to problems, such as spatial decentralization, reduced regional disparities, urban-rural dichotomy in developing countries, to adopt strategies to overcome these problems. The studied area is Rudbar County, Gilan province. The data used in the study included demographic indicators such as the number of households and the growth rate during 1966 to 2011. Using quantitative models, entropy and elasticity, this study evaluates the role of seven cities including Rudbar, Manjil, Lowshan, Jirandeh, Bareh Sar and Tutkabon in development of the surrounding villages. The results of data analysis show that Bareh Sar has a favorable effect on balanced distribution of population and rural settlements, leading to balanced urban hierarchy and spatial distribution. Tutkabon and Manjil are partly able to balance the urban hierarchy. However, Rostamabad, Rudbar, Lowshan and Jirandeh cause population density. It was found that population density is higher in cities due to the available economic and social services.. LQ of Roudbar County is >1 for agriculture and industry and export of manufactured products, while <1 for services, indicating a dependence on other towns. Based on the concentration index, levels of villages in Lowshan, Manjil, Rostamabad and Bareh Sar are regular, while the villages in Jirandeh and Tutkabon are irregular. In addition to administrative and political relationships which result in dependence of villages to cities, people of these towns are referred to other towns of the county for economic, social and cultural relations.Key words: urban function, rural development, Rudbar, entropy model, elasticity model Manuscript profile

Introduction: Nowadays, topographic studies play a crucial role in rural development. Utilizing environmental indices allows the identification of existing flaws in the ongoing rural development plans and projects within the county, preventing their repetition in subsequent policymaking. Considering the settlements' positions within three levels (plain, foothill, and mountain) and natural factors (altitude, slope, direction), the most significant impact on development can be attributed to the environmental factor associated with the altitude level of rural habitats in Shaft County.Research Aim:  The aim is to assess and examine the relationships between natural elements and sustainable development within the studied area and answer the question: Considering geographical factors (altitude and slope), which villages in Shaft County are situated within the unstable range? Descriptive and spatial data were integrated for this purpose.Methodology: This study, characterized as descriptive-applied research, encompassed stages involving the identification of study resources, data analysis, and the creation of tables and maps to assess and examine the relationships between geographical factors (altitude and slope) and sustainable development within the studied area, covering all sampled villages as part of the research population. Based on this, information layers were referenced to the base map, converted into shapefiles, and subsequently underwent a process of merging, clipping, overlaying, and other data mining directives for analysis and integration. Consequently, a model representing the information within the studied layers was generated in the form of a map.Studied Areas: The rural under study belong to Shaft County within Giulan Province.Results: The findings indicate a weak developmental rank related to villages such as Zardkam, Vali Sara, Khorfakel, Vaneh Baneh, Kuchek Koomsar, Dakleh Sara, Moharraman, Mashallah Kal, Aqanur Setan, Lesom, Safidkhani, Tanz, Babarakab, Imamzadeh Ibrahim, and Talghan. In the foothill and mountainous villages (with specific altitude and slope conditions), proper measures haven't been implemented, and the villages are utilizing only the minimum of their capacities for the sustainability of the studied area. This situation solely stems from non-strategic management.Conclusion: The geographical position and natural conditions of each settled rurals within the districts, based on altitude, represent one of the most essential factors required for the development of Shaft County's rurals to plan for providing access to services aimed at increasing the developmental level within the county's district segments. For instance, communication routes, one of the primary environmental factors in rural development, have largely taken shape based on the topography of scattered rurals across Shaft County. However, in each of the four districts, they exist at an unacceptable qualitative and quantitative level in terms of sustainably utilizing the capacities of the county's rurals. Manuscript profile

One of the must important elements in the comprehensivedevelopment in any region is undoubtedly the accessibility of the sweetwater. Guilan located in southern coasts of the Caspian Sea and in northerof Alborz receiving various moist sources, is one of the densely rainedareas in Iran. The presence of different rivers along with the height of thewater table has caused the growth of economic activities dependent onwater. So the abundant of water sources has stopped the officials to thinkof accessing new sources or adapting necessary measures and policies torationalize the use of water sources. Increasing growth of population, lackof adequate instruments for job creation, traditional methods of using watersources along with unplanned development of agricultured area havecaused different problems especially in recent years that precipitation wereinsufficient. This paper has tried to consider the role and place of thewaters sources in the future planning of the State. The research methods isbased on the descriptive statistical methods and analyze of the watersources. Manuscript profile
