The aim of collection will be to share knowledge, which is to promote the value of more knowledge in the organization.

it most of the organizations and companies that move in the fast line of corporate science can't get the top without doing the basic work of directing knowledge in the EFQM model. Substantiative: It was used for use of partial and practical inquiry, and analysed analysis had been taken on two levels of statistics, using the soft instruments of the spss and the pls. The research findings show that strategy, leadership, and least of all to the highest and lowest effect on the welfare of the organization, and that of acquiring knowledge does not affect the most and the least possible effect on the development of knowledge.

Exploring also shows that the key to the development of organized science has a significant effect on the management of knowledge.

The present research was conducted with the aim of investigating the effect of spiritual leadership style on employee loyalty with the role of moderating trust in the organization. The statistical population of the research is the employees of the airport and air navigation company, and the sample size was obtained using the Cochran formula equal to 284 people by simple random sampling method.

The current research is applied in terms of purpose and descriptive-correlation in terms of data collection method. And three localized questionnaires of spiritual leadership style, employee loyalty and trust in the organization were used as research tools. The reliability of the spiritual leadership questionnaire was estimated using Cronbach's alpha coefficient equal to 0.82, employee loyalty equal to 0.82 and trust in the organization 0.79. Also, structural equations were used to test the hypotheses.

The research results showed that spiritual leadership has an effect on employee loyalty, the effect of spiritual leadership on loyalty is equal to 0.41, as well as the sub-components of spiritual leadership (spiritual vision, hope and faith, organizational commitment, love for one another, membership, meaningfulness and performance feedback) have an effect on loyalty,

The results of the research showed that the effect of trust in the organization on employee loyalty is significant, path analysis based on structural equations confirmed the moderating role of trust in the organization between the two variables of spiritual leadership and employee loyalty.

Today, thinkers and theoreticians of international relations believe that the military readiness of any system and government, which is achieved under the shadow of a powerful military organization, is considered one of the key elements of the national power of that system. The Islamic Republic of Iran is not only not exempt from this rule, but its need for a powerful military institution is more than other systems due to the conflict of its goals and ideals with numerous foreign enemies. One of the most obvious aspects of de-institutionalization in the armed forces organization is the crime of desertion, which today has become an organizational problem and is considered one of the most common crimes in the armed forces, the occurrence of which is the result of several factors. Considering the importance of knowing and investigating these factors, in this article, the extra-organizational factors affecting desertion of employees in a military unit have been investigated.The current research is a survey type and its statistical population is 150 employees of one of the military units who committed three or more desertions during their service. Library and field methods (using questionnaire) have been used in data collection.The results of the research showed that the desertion of employees originates from many factors, among the extra-organizational factors, in order: economic problems, emotional and family problems, lack of service motivation, marital status, geographical conditions of the place of work, age and advertisements. The negative ones against the organization have had the greatest impact.

The purpose of this study is to investigate the relationship between resiliency and the quality of worker's life in a military university.

The research method is applied in terms of purpose and is a descriptive correlation type in terms of collecting data. The statistical population consisted of all employees of the university in 2020 - 2021, which according to the confidential information of military personnel, 160 employees were selected as sample in the sample. Data were collected from two resiliency questionnaires and quality of work life. To determine the validity of the questionnaire, content validity and structure were used. The reliability of the questionnaire was also evaluated using Cronbach's alpha coefficient of 0/92. For data analysis, Kolmogorov-Smirnov, T-test and Pearson correlation coefficient were used.

The findings showed that: 1) all resiliency components are higher than the hypothesized mean. 2) The average quality of working life and all its components except the overall living space is higher than the hypothesized mean of the research. 3) There is a positive and significant correlation between resiliency and quality of work life (r = 0.64 and P≤0.01).

The more strength a person has in resilience, coping with life's problems and stresses, the less he is exposed to mental and emotional disturbances and benefits from higher mental health and well-being. More attention should be paid to the resilience of employees, because the quality of their work life is also reported to a very high extent in relation to resilience.

Elements of circular arrays antenna are distributed on concentric circular surfaces with different radii. In this article, the purpose of a case study is to investigate the effect of the arrangement of antenna array elements in reducing the side lobe area, with the aim of reducing the side lobe level and beam width. The reduction of the sidelobe level becomes more prominent when we base it on a maximum beamwidth value for the antenna.

This research is applicable in terms of purpose and the results of this study are presented using simulation - based methods.

The criterion for evaluating the efficiency of circular array antennas in this article is the reduction of side lobes and beam width. In this direction, the aim is to find the distance between the elements, the range of the elements, the number of rings and the radii of the rings, with the aim of the maximum reduction in the level of the side lobes of the radiation pattern. In this review, we have raised the problem of reducing the level of side lobes as an optimization problem and then used genetic algorithm to solve it.

Based on the obtained results, the design of antennas of concentrated ring arrays with non-uniform distribution of elements that have non-uniform excitation amplitude causes a significant reduction in the level of side lobes and beam width.

The perspective of strategic thinking is an insight and understanding that helps officials perform correctly in complex situations and enables managers to understand what factors are effective in achieving the desired goals of the organization. The establishment of Nadaja in the wide area of Makran coast requires management, planning and most importantly strategic thinking. Therefore, the goal of the researchers in this study was to investigate the role of strategic thinking in the success of the Iranian Navy in deploying on the coast of Makran, and the researchers sought to answer the question of what role strategic thinking played in this success. This research is of applied-contextual type with descriptive method and mixed approach. The statistical population of this research includes commanders and senior managers with strategic jobs working in Nadaja, who had the activity of presence and service in Makran beaches. The data of this research has been collected by field and library method by studying documents and documents, searching in reliable websites and submitting questionnaires to the statistical community. The results of the research show that strategic thinking using the components of creativity, foresight, search, intelligent opportunity seeking, risk-taking, observation and monitoring of the internal and external environment, objectivity, vision drawing, strategy formulation, systemic thinking, conceptual thinking, analytical thinking, focusing on Purpose, thinking in time, faith and conscious effort and knowledge of the organization play an effective role in the success of the Navy of the Islamic Republic of Iran in its establishment on the shores of Makran.
