Score for exposure factor is the sum of scores for the five criteria of precipitation, temperature, wind, weather phenomena, and horizontal visibility. Hourly data on precipitation, temperature, relative humidity, weather condition codes, and horizontal visibility obtained at 23 synoptic stations in the Province, and from those located in an area within a radius of 100 kilometers from the borders of it, since the time they were established up to the end of 2012, was first received from Iran Meteorological Organization. Those stations were then selected that had data related to eight daily measurements in the interval 1990-2010. Based on this, data processing was carried out for nine stations (five in Kermanshah Province and four in neighboring Provinces) within MATLAB environment. The scores for exposure factors for climate change in two five-year intervals were calculated to assess climate vulnerability of Kermanshah Province. In the next stage, the study period was divided into three intervals: the base interval (from 23, 9, 1990 to 21, 9, 2000), the first interval (from 22, 9, 2000 to 22, 9, 2005), and the second interval (from 23, 9, 2005 to 22, 9, 2010). Following that, exposure criteria and markers were determined. It was then necessary to define and measure a broad range of markers because of the temporal-spatial non-uniformity in the climate of Kermanshah Province that results from land location and variety in this Province. In the present research, climatic data was processed in the framework of five criteria that included 29 markers. In general, it was found that Kermanshah Province is faced with increased hazards resulting from current changes in climate.

Historical fabric of Arak, as one of the most important inorganic cities in urbanization history of Iran, has been implemented from the beginning based on predetermined plan and project. During the age that majority of cities in Iran used to be created organically and gradually based on public needs, all steps of construction of Arak City including spatial organization, physical structure, communicative network system, activity distribution pattern and composition of urban elements were firstly designed and then implemented. The main objective of this study is to identify and analyze the physical features of monuments of Arak city to discover the behavioral system of monuments with the composition features standard. According to the research objective, the method applied is descriptive, analytical and comparative method based on field and library investigations. In this study, first architectural composition features including scale, proportion, hierarchy, axis, focus point, composition center, modulus, flexibility, rhythm and geometry are analyzed in each monument. Then, the monuments were classified in sub-factors of each composition feature and then, through comparing the classified groups, common features of monuments in each sub-factor with most frequency are extracted. The results obtained from the study showed existence of unit behavioral system in special groups of monuments compared to architectural composition features leading to typology of Arak’s historical monuments.

One of the aims of spatial political management is to increase access to social and economic services to all residents in an area in order to enhance their satisfaction. There is a great space in the action that has a broad scope. If the spatial political organization implemented in a country is unable to organize such services in a condensed manner, it will face reduced efficiency and lack of satisfaction of its residents of their access to economic, socio- cultural services, so it will lose its political authority before its residents. The distance between the rural- urban centers of the Great Khorasan province to its capital (Mashhad) along with its consequent complications have always been one of the problems of this Great province before conducting the political divisions of the province in 2004. One of the most significant purposes of assigning the law of the state divisions in the province has been to lower its physical distance to the political center of the province and to increase the socio- economic facilities provided to raise its inhabitants’ satisfaction. The present reearch was conducted using a descriptive- analytric approach to analyze the effects ofthe state’s divisions and to increase the effect of the political centers (Birjand and Bojnord) on thesatisfaction level in terms of economic, socio- cutural needs of the citizens in the North Khorasan province. The resultsshowed that reducing thedistance created in the political divisions of the province and adjacency of the urban rural centers to the political sites in the province has failed satisfying the satisfaction of the local residents of these areas.

Human is a compatible creature with the ability to grow the modern knowledge and new patterns of activity. Social pressures and cultural norms could affect formation of behavioral patterns and attitudes of urban planners. However, the framework is not static and could be changed over the time and the urban planners are responsible for controlling, conducting and evaluating the reflection of these changes and playing role in their formation. It should be noted that with such speed of changes in the current cities, realization of a degree of flexibility if required and the future prospects could clear flexible and creative cities as the contexts for economic, social and cultural development of societies and urban spaces could be important sites to meet needs of citizens and formation of social activities. Now in this study, which is a descriptive-analytical research in terms of nature, the main objective is to recognize required components in formation of flexible urban space in Iran and to measure the perceptions and expectations of flexible urban spaces in Iran. It should be mentioned that achievement of these spaces with flexibility capabilities needs firstly some preconditions including accessibility, diversity and readability. In this regard, at the first, qualitative data are collected using library method and the literature is reviewed to identify the most important components involved in formation of flexible urban space and then, the data are measured in frame of Delphi Method. Then, to clear the differences between expectations and perceptions, a questionnaire is used for paired mean comparison of components. Due to the difference between the existing and expected conditions, this issue was confirmed. Finally, for better understanding of the difference and using the gap scatter plot, relevant factors of physical system and energy were placed in the part of balanced and fixed factors, factors related to spatial and functional system and meeting needs of citizens as the problem and relevant factors of formation process and role of citizens in growth balance were observed.

the aim of this study is explaining the relationship between social trust with citizenship ethic. The study population consisted of all high school students in Bushehr city that among this population, a sample of 360 students were selected by multistage random sampling method. the research tools included multi dimension comparison of recognized social support, questionnaire of social trust and citizens ethics questionnaire. To analyze the data, statistical methods such as Pearson correlation and multiple regression analysis were used. Pearson correlation coefficients showed that between Social trust and its dimension such as trust-based behavior, cooperative tendencies, openness, honesty and reliability has significantly relationship with ethics. Multiple regression analysis showed a significant positive relationship between aspects of social trust with citizen’s ethics. Predictor variables explain 22% variance of ethical citizens among high school students in Bushehr city. Among the predictor variables the cooperative intentions was the best predictive of citizens ethics and at the end the suggestions and necessary solutions were presented.
