According to the non-physical aspects of conservation in the world today and intangible effects were considered serious. Conservation process, but help to understand the purpose and effect of not reading, but perception is a matter of epistemological roots in philosophy and in modern philosophy the process of understanding a monument-art conservation in connection with the audience is important. The audience as an integral part of the conservation that is effective in the formation of the protective interactions. So how to understand and get the audience's perception of the effectiveness and value in him is vital. On this basis, the aim of this paper is to review and reach the audience in understanding how the process is the philosophical foundations value conservation and the main question raised is whether the formation is based on the principles of philosophy devoted to protecting the perception place? To access the call to review the evolution of the contact position in this field and the principles of conservation and understanding of the philosophy and the philosophy of protecting reviews override and analysis and review of the vote, Islamic and Western philosophy has been done in this area. This study is an analysis of the findings found that the effect of that sensory perception, rational and imaginary in philosophy, has been developed and subjective and objective process, in discussing his philosophy of conservation for immediate steps to get the whole effect, thinking the values of work, interpretation and effect of the appreciation of the presence and reading of this show that understanding the importance of the three principles behind the creation and validation of the integrity, authenticity and value perception lies and categories subject to the special relationship with the audience taking effect. When the relationship between the audiences with a monument is established on the basis of perceived value can be expected readings mean conservation will take effect.

Passive Defense is a set of civilian efforts performed to enhance deterrence, reduce vulnerability, sustain essential activities, promote national stability, and facilitate crisis management against military threats of an enemy. Since in battles, sensitive and critical areas of cities are of paramount importance,it is clear that in military agressions, a large part of threats are focused on cities and their urban facilities and equipment, especially fuel centers. As a result, consideration of passive defense while planning cities has a significant role in reducing the vulnerability of cities and their urban elements as well as facilitating the urban crisis management. It also provides the citizens resistance threshold under possible enemy invasion and natural malicious agents. Hence, this article reviews and analyzes the current situation of gas distribution centers and evaluates their positioning across the city of Mashhad with regard to passive defense approach. However, as far as there is no clear- cut criteria for organizing fuel centers with passive defense approach, the Delphi method is used to select the desired criteria in which on the basis of the final comments of the experts, four critera- performance, access, hazards and security election and spatial organization of the fuel tanks and petrol stations- are analyzed using AHP model and GIS spatial analyzes. Accordingly, it can be said that the assessment of the current status of the urban fuel stations in Mashhad indicates that no area of the city enjoys all measures of passive defense (performance, availability, security, and risks). Likewise, the results indicate that the distribution of these centers in the city are mostly consistent with the factor of access. taking into account all the criteria, it is the ​​North West of Mashhad which has the highest utility than other areas. It is followed by the east of Mashhad and ​​the Northeast and the middle east of the city, respectively. Accordingly, it could be stated that ignoring an efficient design for determining the optimum location of the site construction with a passive defense approach results in an inappropriate and naive spatial distribution of the stations leading to an increased security and environmental risks of the city.

Utopian thoughts have precedence as old as human history. Islamic civilization utopian thought owes its progress to the Farabi&rsquos utopian concept and expansion and academic study of utopian term in west owes to the Thomas More Utopia book. Theoretically, Farabi&rsquos utopian thoughts influenced development of utopian system in both Islam and Western civilizations. By emphasis on Farabi&rsquos Utopia as an example of utopian ideas in Islamic civilization, and Thomas More&rsquos Utopia as an example of utopian though in the western civilization, this research tries to investigate the commonalties and differences of these utopias. The architectural and urban building spaces of these examples were studied in the conceptual viewpoint. Thomas More Utopia consists of fifty four similar cities. All of the cities have been constructed well according to the same plan as possible as. The nearest cities have approximately twenty four miles distance, and the furthest ones are not so far from each other so that the people can travel less than one day. Because of similarities in the cities, only one of them has been referred in the &ldquoUtopia&rdquo this city is Amaurot. Each city sends three wise old men to Amaurot every year to negotiate on their common affairs. Amaurot is the main city of the island and it is near the center of the island. &ldquoThe opinions of the Utopians&rdquo and &ldquoThe Policy of the City&rdquo are two books of Farabi. He expresses the political and philosophical systems of Utopia comprehensively. He divides communities qualitatively and in addition, there are cities in contrary to Utopia. He pays attention to the quality of communities from perfectionism and auspicious perspective. In other words, the goal of the city determines type of the city. Farabi likens utopia to a creature that has independent existence beyond the members of the city. The comparison of the architectural and urban building spaces of Farabi&rsquos utopia and Thomas More&rsquos utopia showed that both of the cities are placed in the defined space from urban structure perspective both of them have defined volume and level, and the difference is that Thomas More&rsquos utopia is located in an islands and Farabi&rsquos utopia is universal. The More&rsquos city has a defied localization but Farabi&rsquos city does not posse this characteristic. Farabi has referred to the market space and transaction regarding to the urban micro spaces while Thomas More has referred to passages, hospitals, market and hall and other specification, situations and services. More has not explained the social and geographical divisions, but Farabi divides his utopia into complete and incompetent city and offers subcategories of human communities. Thomas More has emphasized on the urban divisions on streets and fragmentation of the city and also has referred to details like type of material, material used and entrance of city while, in Farabi&rsquos utopia has no references to the details of the architectural spaces and he has emphasized on educational and social goals.
