Due to its neighborhood with Afghanestan and the subsequent problems of this country such as insecurity, weak economic conditions, and lack of proper border monitoring, Khorasan Razavi Province has always been the inhabitat of numerous foreign nationals. Legal and illegal entry of these people has created plenty of issues from different economic, social, and cultural aspects for the citizens of this province. Negative consequences arising from the presence of foreign nationals on one hand and threats that may form from the Trans powers (using the nationals) have emphasized the necessity of considering the passive defense issue. So, one of the issues that requires further investigation is the security implications of foreign nationals in Khorasan Razavi province in terms of a passive defense approach. The main question of the current research is that of regarding the passive defense viewpoint, how the presence of the foreign national affects the security of Khorasan Razavi province and the Islamic Republic of Iran in general. This study has a cross-sectional study approach and through library studies, along with a comprehensive perspective, different threats are identified in the field. Proposing practical solutions, it attempts to take effective measures in controlling such consequences.

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.

In this article, it has been tried to analyze the mental satisfaction of the quality of life in different regions in terms of objective development. For this purpose, districts no. 3, 6, and 9 of Mashhad city which through the measures of education, income, and employment were respectively among the deprived, the average, and the privileged regions were selected as the case study areas. Moreover, to measure the mental satisfaction of the local people of the quality of life, a questionnaire considering three basic dimensions of quality of life, i.e. economic, environmental, and physical sustainability (residential environment, the quality of these infrastructures) was designed. The sample size equals 385 people who according to the population of study area were divided into clusters. The research findings showed that there is little or no significant difference between these districts in terms of the desired measures, so that in terms of economic issues, the district no. 9 had a better condition than the other two. There was no significant difference between the districts no. 3 and 9. Regarding satisfaction of the quality of housing and infrastructure, the inhabitants in the district no. 6 showed less satisfaction than others. In this regard, no significant difference was observed between the districts no. 3 and 6; however, regarding satisfaction of the environmental situation, there was a significant difference between the districts no. 3 and 9, whereas the district no. 6 was an exception. Generally, the district no. 9 in Mashhad has a better condition in terms of objective development, social status, and quality of mental life. In contrast, regarding these indices, the district no. 3 is among the poorest regions, so in terms of quality of mental life is in a average state. Yet, the district no. 6 due to its development and the middle social status has a less unfavorable condition in terms of the quality of life.
