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.

Traditional bazaars have been at the center of tourism attractions in the world and regardless of the passage of time and change in culture and people’s life, it has preserved its status. This paper aims to recognize the values, concepts and the inner meanings in bazaars of Kurdistan. In the case study of bazaars of Sananadaji and Asef located in Sanandaj and Qeisar-I Naqib bazaar located in Sulaymaniyah a pattern is presented to determine the main effective components on sense-making along with tourism development. For this purpose, qualitative-quantitative research methodology has been employed. In qualitative part of the research, some interviews with 16 experts have been conducted, and by applying open coding method, 105 keywords have been recognized and derived, which ends up creating a 74-question questionnaire in eight components. The questionnaire has been standardized by applying content validity and Cronbach’s alpha coefficient and was distributed among people by applying Cochran sample size determination and stratified sampling, and considering the optimum allocation of 190 Persian questionnaires among the people in Sanandaj bazaar and 40 Kurdish questionnaires among people in Sulaymaniyah bazaar. The results of confirmatory factor analysis led to recognize five components; they were 38 percent of the total variance coverage. According to the results of confirmatory factor analysis, the final model based on the components was confirmed. Among those components, emotional-perceptual and technical-physical components with the highest factor loading have been recognized as the most effective components of sense-making in the aforementioned bazaars along with tourism development.
