Abstract
Rural guide plan is the main comprehensive plans for the development of the rural regions in Iran. Since 1987, more than 16440 projects have been provided and 7670 projects have been implemented. Despite more than 20 years after starting the rural guide plan, the plan is still running in the many rural regions of the country, therefore, the study of the consequences and effects of the plan is very critical, because these studies provide the necessary data and information for the managers through a feedback process, so the managers can choose better methods for the future plans. In addition to this, the weakness and barriers of the plans will be identified clearly in order to get more appropriate solutions. In this respect, the main purpose of this study was to identify and analyze the effects of implementing the rural guide plan in the Sarin Dizaj village of the Osko county. The research method of the study was quantitative, non-experimental and field research in terms of the nature, the rate degree of variables control and the method of data collection, respectively. The statistical population of the study consisted of all heads of rural households in the village (N= 213). According to the Krejcie & Morgan table, a sample size of 130 was selected using a simple randomized sampling technique. A questionnaire was used to collect the data. A panel of experts confirmed the validity of the questionnaire. A pilot study was conducted to establish the reliability of the instrument. The Cronbach 's Alpha coefficient for the main scale of the questionnaire was higher than 0.75. The results of a factor analysis showed that five factors namely, structural- physical (with 20.25 % of variance), social (with 19.63 % of variance), sanitary (with 14.42 % of variance), economic (with 10.63 % of variance) and environmental (with 4.86 % of variance) explained 69.79 % of total variances of the effects of implementing the rural guide plan in the Sarin Dizaj village in which two factors including structural- physical and social had the highest priority.

Abstract
Climatic design and attention to the discussions of sustainable architecture, which have been considered as the most important issues of contemporary architecture, have thousands of years of history, especially in Iran. Nowadays, climatic design is a rational reaction to the crises caused by the shortage of energy resources and increasing environmental pollutions which have been created by fossil fuels. In Iran, one of the climates that attention to its ecological conditions is vital for creation of thermal comfort and climate architecture is hot and humid climate which is facing high heat and humidity. In these regions, provision of ventilation and cooling by mechanical equipment requires to spend a great deal of energy and cost. In this paper, considering the discussions of climatic design in hot and humid climates of Iran, attempts were made to offer an appropriate physical mechanism (related to the optimal shape of roof and natural ventilation) to use natural ventilation in the residential buildings of Chabahar which are located in hot and humid climates and face the problem of heat and humidity. The research method used in this paper was descriptive analytical and computer modeling and numerical simulation by Autodesk Vasari software were applied to evaluate appropriate roof shape and efficiency of wind tower and wind scoop in the natural ventilation of residential buildings of Chabahar. Results of the computer simulations by Autodesk Vasari software were validated by ANSYS CFX software. The required information and data for this paper were collected from meteorological stations and valid documentation and library resources.
Warm and humid air has a tendency to stay stagnating and, for ventilation, airflow must be used. In low-height and surrounded buildings where the facade of which is not encountered by appropriate airflow, roof has an essential role in the mechanism of natural ventilation. Furthermore, the airflow that crosses the roof is more stable and stronger. In this paper, through studying and modeling three kinds of roof (curve, steep, and flat) and their appropriate wind tower and wind scoop, appropriate roof shape and efficiency of wind tower and wind scoop in natural ventilation were evaluated and optimal physical mechanism of natural ventilation in the residential buildings of Chabahar (villas and apartments) was investigated. Finally, optimal form of the roofs (related to natural ventilation) and their wind tower and wind scoop were recommended to be used as the patterns of vernacular architecture in Chabahar city.

Abstract
City, as a symbol of the physical conditions of cultural, social, political, and economic factors in each era, serves as a criterion for evaluating societal changes in that period and the urban environments are considered as a physical realm for interactive actions with defined boundaries, enabling the concentration of social interactions in various ways. Strengthening and expanding suitable, active, dynamic, and enjoyable urban environments is always at the forefront of the goals of urban designers and planners in strategic efforts to enhance the quality of urban environments. Especially today, when the quality of public spaces has declined and social creativity in urban areas has diminished, identifying the unconscious factors that can influence social creativity has become a concern for urban planners and designers. In light of this, the main focus of this research is to identify the unconscious factors present in the environment and their impact on social creativity. To achieve this goal, residents of three neighborhoods in Ahvaz, namely man bae Ab, Nioside, and Ameri, were selected as the statistical population for the study, with a sample size of 380 individuals. The research questionnaire was distributed among the members of the statistical population using random sampling. The data analysis was conducted using factor analysis and structural equation modeling in software programs such as SPSS and Amos. The findings of the study showed that 13 identified factors can explain over 68.54% of the variance in social creativity in urban spaces. Additionally, factors such as social capital, motivation for talent and abilities, responsiveness of space and experience of place-making, culture, traditions, and community beliefs, authenticity, diversity, and uniqueness of space and furniture were ranked as the top four factors influencing social creativity in urban spaces.

Abstract
With the increase in population growth and rising land and housing prices, the size of residential apartments in major cities has decreased, leading to intrusion into the privacy and personal space of apartment residents. However, since there needs to be an environment that allows for certain behaviors to occur, one can utilize the existing capabilities of the environment for privacy selection. This study adopts a combined approach and utilizes descriptive-analytical and exploratory methods to examine the nature of privacy and how it can be achieved through the theory of environmental capabilities. The research question posed in this study is how one can utilize the theory of environmental capabilities to achieve privacy selection in low-rise residential apartments. To answer the main research question, after conducting library studies and reviewing theoretical foundations, a number of case studies were selected and their current situation was examined from the perspective of feasibility assessment using the theory of environmental capabilities for privacy selection. In continuation, based on the regulated components and the existing situation in the case studies, specialized questionnaires were provided to the statistical community. The data analysis method in this section utilized T-Test, Friedman test, factor analysis, and structural equation modeling, using smartpls3 and spss22 software. The research findings indicate that the "cultural-social" dimension has the highest impact with an average rank of 2.43 in terms of privacy selection and its realization in housing by residents. Following that, the "physical" dimension with an average rank of 2.01 and the "semantic" dimension with an average rank of 1.56 have the most influence on the privacy selection of residents in low-rise residential apartments, after the "cultural-social" dimension. According to the research results, one of the reasons for the decline in the quality of privacy selection by residents is the designers' focus on functional features in design and neglecting cultural features and behavioral patterns.
