One of the most obvious aspects of successful management and planning during the imposed war was the management of aid to the wounded in the form of establishing military field hospitals with passive defense approaches. So that the aforementioned action was developed from creating a tent or a roofed frame for relief at the beginning of the war to the construction of field hospitals in terms of passive defense requirements. In this way, the average duration of sending war wounded during the holy defense period in some fronts of the battle of right against falsehood to medical centers was reduced to less than one hour at the end of the imposed war, and by complying with the requirements of passive defense. Various factors are effective in the construction and establishment of a field hospital, which can lead to the improvement of the hospital's performance and reduce the risks of its construction and establishment while meeting the requirements of passive defense. Identifying these factors in the form of a scientific model during the occurrence of civilian crises in the construction and establishment of a civilian field hospital with a passive defense approach is also of great importance. The current research was conducted to identify the relationship between these factors to facilitate the management and provision of services to the wounded during the war and possible crises with the approach of passive defense. For this purpose, a main hypothesis and nine sub-hypotheses were designed and tested. This research is applied in terms of purpose and descriptive correlation in terms of method, in which exploratory structural equations were used. The statistical population includes military-scientific experts, 17 of whom were selected by purposeful sampling and the Delphi method until theoretical saturation was reached. The data collection tool is a structured interview method and a researcher-made questionnaire consisting of six dimensions, 11 factors, and 66 measures. Confirmatory factor analysis and PLS software were used to test the hypotheses. The results of the measurement model criteria (measurement reliability criteria, measurement model reliability, and divergence convergence of the model constructs) as well as the structural model criteria (determination coefficient criteria and model prediction suitability) indicate the optimal fit of the proposed model. Also, based on the t-value results, the main hypothesis and all sub-hypotheses were confirmed. The results indicate the direct effect of the "quality of management and command of the field hospital" dimension on the dimensions of "providing financial resources for providing specialized identification and treatment equipment", "providing general and specialized infrastructure of the field hospital" as well as "providing human resources of the field hospital". Of course, the "field hospital management and command quality" dimension has the greatest impact on the "field hospital treatment quality" and "field hospital readiness and support quality" dimensions. Also, the results showed that in addition to the dimension of "field hospital management and command quality" directly, positively, and significantly affects the dimensions of "providing general and specialized field hospital infrastructure" as well as "providing field hospital human resources"; The dimension of "providing financial resources for the provision of specialized identification and treatment equipment" also plays a full mediating role in these two relationships.

The main objective of this research is to assess the vulnerability of infrastructure in West Azarbaijan province. For this purpose, the process of evaluation has been taken using the GIS. The research method is descriptive-analytic. In this research, a multi-criteria decision making model has been used to overlay the layers. The relevant spatial data has been collected from official centers and authorities of the country, and for measuring and determining the criteria, documentation in form of written sources, and questionnaires filled in by local residents and experts have been used. The results of this study indicate that the spatial distribution of infrastructure in the West Azarbaijan province is concentrated and follows a cluster pattern, and this kind of distribution multiples the spatial vulnerability of the infrastructure. Also, 10 percent of the infrastructure of the province is considered as a sensitive and important infrastructure (from provincial viewpoint), of which 45 percent of the infrastructure of the province is exposed to very high vulnerability, 16.6 percent high vulnerability, 14.2 percent moderate vulnerability, 16.4 vulnerability and 12.5 very low vulnerability. Also, the results show that the border areas of the province such as Sardasht, Piranshahr, Oshnavieh, Salmas and Maku are vulnerable regions, which need urgent attention if new infrastructures are established. Also, the results of the research particularly the density of vital and sensitive infrastructures of the province in areas of high and very high vulnerability indicate the lack of optimal management of spatial deployment of infrastructure in the province.

Vulnerability assessment of critical infrastructure is always a major concern for the country's leaders in the field of strategic management, monitoring and evaluation of the safety and security situation. To deal with the vulnerability of infrastructure and the probability of threats against them and the use of safe and efficient deterrent, it’s necessary to identify the important factors that causes damage to the infrastructure .One of the effective factors contributing to identify infrastructure is sound waves emitted by the infrastructure that has so far received little attention. The main innovation of this study is the vulnerability assessment of the infrastructure against threats that use acoustic sensors. Due to the uncertainty in predicting the behavior of acoustic waves, sensors and radar systems and the need to spatial analysis to assess the vulnerability, in this study have been trying to use fuzzy logic to model the behavior of the parameters used in the framework of a Geographic Information System. The model was implemented for the region around Natanz with hypothetical information and vulnerability map was presented at the end. Distribution of acoustic waves around infrastructure, position of radar systems, the ability to define the space around by radars and sensors are effective factors in Vulnerability assessment. Considering the hypothetical positioning, infrastructure accessible by unmanned aerial threat in a path on the southeast side. Location of radar systems, the ability to define the space around the sensors detected by the system, as well as the vulnerability of infrastructure is a decisive factor. Location of radar systems can be used to cover the access paths to minimize the vulnerability of infrastructure.

Passive defense, and its new ways are considered As an integral tool of crisis management. In recent years with the introduction of passive defense issues in various fields of applied science which is coincided with The emergence and rapid growth of science and the crisis management methods, Rescue as one of the pillars of crisis management, The greatest impact on the preservation of human capital in the event of natural disasters and man-made play And from this point of view has found an important role in crisis management issues. The present article, using descriptive-analytical method examined passive defense in relief and rescue And choosing "The role and application of passive defense in the relief and rescue the Red Crescent Society of IRAN" As its main objective, Seeks to answer the following research questions: " A. What is the role and function of passive defense in the relief and rescue of the Red Crescent.? " And hypothesis that "Passive defense is effective in the relief and rescue of Red Crescent Society" Evaluated And finally to the conclusion that Although man-made disasters and new threats are rising, do to the conclusion that... But the most effective and cost effective methods of passive defense is still available In order to reduce vulnerabilities and improve the quality of the field of crisis management and rescue organizations are considered.
