Given the close relationship between military affairs and climate change, military organizations need to consider the potential effects of climate change in their future planning and design. In this study, in order to investigate the effects of climate change on military activities in Isfahan province, we used the simulated output of the hadGEM2-ES paired model from the CMIP5 model series, based on RCP 8.5 (pessimistic) and RCP 4.5 (optimistic) radiation induction scenarios. Has been. Also using Misnard Bioclimatic Climate Index (ET) and also using GIS software in interpolation, generalization of point-to-area data and combination of maps, times and places suitable for military activity in terms of body physiology in Isfahan province during a 20-year statistical period (2019-1999) and for the next period (2040-2059). Data analysis showed that September is mostly in the province in optimal conditions for military activity, which in the basic period is more than two scenarios pessimistic and optimistic. Based on the results obtained in the summer, the highlands and in the spring, the lowlands of the province have been selected for optimal military affairs, and in the winter and autumn (November and December) cold conditions prevail, which according to the data obtained from the amount in the pessimistic scenario, the Misnard index tends to the lower edge of the cold class.

Conducting non-industrial researches to enhance the strength and dynamism of the armed forces is not a current effort, but a basic necessity and a transformational movement. Therefore, the army of the Islamic Republic of Iran, which has the serious task of maintaining the independence, territorial integrity and security of the country's borders, by Realizing this important, during the last three decades, it has taken various activities for the growth and development of non-industrial researches at different organizational levels. However, the activities carried out are far from reaching the desired point. Therefore, this study was conducted with the aim of presentation of appropriate strategies for non-industrial researches of the Army of the Islamic Republic of Iran. This research based on the Achievement is applied research and based on the nature and an objective of the research is a descriptive type that was done with the case study method.  The statistical population of the study was qualified experts whose points of view were used in the research process. In addition to strategic analysis techniques, Summative Content Analysis method was used to analyze the data. Research findings show that in order to develop and promote AJA non-industrial researches, seven categories of transformation strategies should be included in the agenda of AJA headquarters. The most important of which is the optimization of the structure of AJA non-industrial researches and also the empowerment and training of commanders and managers of AJA non-industrial researches centers and offices.

The growing trend of technology and the development of a network approach in the future in various military and civilian areas on the one hand and its impact on defense systems on the other hand emphasizes this important that Considering the intelligence and automation of the new generation weapons and carrying out missions under the control and guidance of the command and control network, in order to use networks such as IoT, it is necessary to always monitor the threats and technologies used to eliminate weaknesses and Improved defense readiness.Crucial strikes using a variety of modern equipment and weapons have made air defense systems covered by an integrated network at the forefront of the conflict and a top priority in defense matters. The main purpose of this research is to study and analyze the use of IoT in the air defense network from the perspective of injuries and threats. In order to enumerate environmental factors, the statistical population, including 16 experts in the field of air defense and network and familiar with strategic defense issues, was purposefully used for in-depth interviews.Findings of the research include 13 sub-categories (external and internal environmental factors) challenges. Finally, 9 sub-categories related to the 5 main categories have been determined and ranked, and at the end, related suggestions are presented in line with the research goal.

Employees can perform their tasks well when they have the necessary skills, knowledge and ability to know the goals of the organization well. One tool that can help managers in this regard is the process of psychological empowerment. The present study examines the dimensions, components andindicators of an effective model of psychological empowerment of AJA university staff from the perspective of experts of this organization. The research was applied in terms of purpose, qualitative in terms of approach and descriptive in terms of research method. The statistical population of the study consists of all DAFOOS AJA experts in the field of psychological empowerment who have a thorough knowledge of the organization and its goals and tasks. The sampling method was purposive and the number of samples continued until the theoretical saturation (in this study, the theoretical saturation was 10 experts). The assessment tool was a semi-structured 60-item questionnaire that was collected by the researcher, which was collected after reviewing the previous findings and then sent to the experts in two stages using fuzzy Delphi technique, and finally 61 final questions were obtained. Findings indicate that the effective model of psychological empowerment of AJA University staff, consisting of 3 dimensions of individual, organizational, meta-organizational and 12 components of personal traits, mental health, belief, moral, special abilities, management strategies,Organizational culture, organizational structure, cultural - social, economic, political-legal and technological.

Today, the evolution of methods of warfare and the development of weapons add to the need of increasing defense methods, including attention to the requirements of passive defense in order to increase the defense power of combat units. Therefore, this study was conducted with the aim of comparative study of combat garrisons stationed in the northeastern regional of ground force from the perspective of passive defense. Considering the location of some units of this base in the border provinces, having major forces and military resources and the special importance of these units, observing the requirements of passive defense, will have a significant impact on increasing their defense power. Therefore, in this descriptive-analytical study, the importance of 10 passive defense indices selected by library studies was compared by 20 military experts in the Likert spectrum and then evaluated by Macbeth technique, due to protective consideration, they have been analyzed by coding. The results of this technique emphasize the importance of scatter and camouflage indices more than other indices. The application of these criteria, considering their coefficient of importance in the Prometheus method, showed that the 37 M Brigade is in a very good position in terms of observing passive defense indicators. 15 Sh and 27 Q brigades are also acceptable. But the brigades of 25 ch, 17 T, 38 T and 23 G are facing a crisis in terms of passive defense.

The purpose of this article is to develop a model for improving the effectiveness of military-scientific classes by considering the mediating and two-way role of students' cognitive characteristics in a military higher education center. For this purpose, one main hypothesis and seven sub-hypotheses were designed. This article is applied in terms of purpose and descriptive-survey and cross-sectional in terms of method. The statistical population of the study includes all professors of the higher education center studied in the second semester of the academic year 1399-1400. The data collection tool is a researcher-made questionnaire, the validity of which was confirmed by content method and its reliability was confirmed by calculating Cronbach's alpha and factor analysis. 435 questionnaires were completed. Structural equation model was used to test the research hypotheses. The results indicate that the main hypothesis (based on the Variance Accounted For index) and all sub-hypotheses of the research (based on t-value) were confirmed. In other words, the existence of effective communication channels between professors and commanders as well as educational, personal, disciplinary and cognitive characteristics of students have a positive and significant effect on promoting the effectiveness of military-scientific classes of military university students under study. Of these five dimensions, however, the dimension of students' cognitive characteristics with a path coefficient of 0.99 has the greatest impact on the model, because a change of as much as a standard deviation in the dimension of students' cognitive characteristics will cause a change of as much as 0.99 standard deviation in the pattern of improving the effectiveness of scientific-military classes. Also, students' cognitive characteristics, in addition to a strong direct effect (with a path coefficient of 99%) play the role of complete mediation between students' educational characteristics and their individual characteristics by promoting the effectiveness of students' scientific-military classes.

Submarines can be identified in several ways, which acoustic noise is one of the most important of them. In submarines, the highest score is acoustic stealth. Acoustic noise emission is very important in detecting the position of the submarine; Because it can be emissioned at high speed and over long distances according to the nature of the sea environment and can be detected and classified. Considering the impact that submarines had on World Wars I and II as a result of the war and the importance of their presence in naval wars, reducing acoustic noise, in addition to hiding the submarine from the enemy, makes submarine sonar systems more efficient (in detecting operation). Sources of noise production in submarines are divided into three categories: hull noise, internal machinery and equipment, and propulsion system, especially submarine propeller noise. In this research while studying on the source of noise production in submarine, the active and inactive methods for reducing the submarine acoustic noise has been investigated. The first step in eliminating or reducing noise and controlling it, is to know the mechanisms of noise production and emission, so that subsurface operations can be performed in complete secrecy. In order to reduce noise, we can use the first effective methods that are applied directly to the source of noise as well as the secondary method (active and inactive) that is applied to the emission path and the submarine hull. This research is an applied, descriptive method with a mixed approach that collecting real and detailed information, the researcher has expressed the methods of reducing acoustic noise in subsurface operations. In this study, the value of the statistical population is limited and specified to the subsurface flotilla of the first naval district in Strategic Navy of the Army of the Islamic Republic of Iran (I.R.I.N). Therefore, the sample size corresponds to the size of the statistical population of 86 people. Finally, after collecting the data, the researcher performed Cronbach's alpha tests and T-test to investigate the relationships between variab les with noise reduction.

The division of the country is one of the most important issues in any country, which plays an important role in land management, and must be done in a desirable way to be able to achieve its duties of providing security, optimal management of space and gaining the satisfaction of land dwellers. . Therefore, for this purpose, the injuries and weaknesses that exist in the divisions of the country should be properly identified and the necessary efforts should be made to eliminate and turn them into opportunities. For this reason, the present study was conducted to identify the damages that exist in the system of divisions of Iran from a political and security perspective; Research method This research has been done both quantitatively and qualitatively. In this way, first by studying the research literature, the injuries in the country divisions were identified and then using a questionnaire and analysis by SPSS software and T Test were assessed by experts to be confirmed as injuries. Or reject them. Based on the research findings, the weaknesses and weaknesses of Iran's divisions in the country were classified into three dimensions: geographical, political-administrative and security. After examining the above-mentioned cases, it was found that all the above-mentioned injuries have been approved by experts as a challenge and a weakness in the divisions of the country.
