The agility of defense project-oriented organizations in carrying out innovative research projects is necessary in order to increase the level of defense deterrence against the threats caused by various military products in the world. Therefore, the current research was developed with the aim of investigating the effect of using knowledge management on organizational agility with the role of mediating innovation in defense project oriented organizations. This research is of applied type and its method is descriptive correlation type which was done by survey method. The statistical population of the study was made up of 73 defense research units, and an effort was made to collect and analyze data from the entire statistical population. Lawson, Jimenez, and Wang and Sharifi questionnaires were used to measure the variables of knowledge management, organizational innovation, and organizational agility, respectively. In order to check the validity of the research questionnaires, the opinion of 5 experts was obtained and after making the necessary corrections, its formal and content validity was confirmed by them. Also, Cronbach's alpha coefficient calculated as 0.894 confirmed the reliability of the research questionnaires. Structural equation modeling technique and Smart-pls software have been used to confirm the research conceptual model and research hypotheses. The findings of this research showed that the application of knowledge management has a positive and significant effect on the agility of defense project-oriented organizations with a coefficient of 0.498 and also through organizational innovation with an indirect effect and with a coefficient of 0.363, it can improve organizational agility. Therefore, defense project-oriented organizations should focus more on the effective implementation of knowledge management, so that by strengthening innovation and improving the level of organizational agility, they can respond to the rapid changes in the defense environment and create a suitable level of defense deterrence.

The translation, adaptation and normalization of standard tools provide a useful opportunity to test the applicability of tools in other societies, and a basic step in proving that test is whether the pattern of concurrent problems identified by the tool in a society matches the identification patterns. made by that tool is suitable in other societies. Therefore, the aim of this research is to standardize the green knowledge management questionnaire among the experts of the Ministry of Sports and Youth of the Islamic Republic of Iran. The statistical population of this research was formed by the experts of the Ministry of Sports and Youth (N=320), from whom 273 questionnaires were collected in the form of available sampling. In order to collect data, the green knowledge management questionnaire made by Siming et al. (2022) was used, which consisted of 26 questions. In order to analyze the data, descriptive indices and statistical tests of Cronbach's alpha coefficient, McDonald's omega coefficient, theta coefficient, exploratory factor analysis and confirmatory factor analysis were used in SPSS, Lisrel and Stata statistical software. The results showed the reliability of the questionnaire (α=0.958, Ω=0.971, θ=0.983). Regarding construct validity and based on the amount of relationships and significance level, all the questions had a significant relationship with the components and were able to be a good predictor for their factor. The ratios of X2 to df are equal to 2.58 and (RMSEA) which is equal to 0.075, so the model has the necessary fit. Also, the indices of NFI=0.95, CFI=0.95, GFI=0.91, AGFI=0.90 and IFI=0.96 confirmed the fit of the model. Regarding the relationships of the components with the concept of green knowledge management, the results showed that the components of knowledge creation, knowledge acquisition, knowledge storage, knowledge sharing and knowledge application were able to be good predictors for the desired concept and therefore have a significant impact on experts' environmental knowledge. As a result, the internal and external validity of the "green knowledge management" model has been confirmed and this tool can be used to collect the required data by researchers.

The purpose of this research is to investigate the effect of knowledge hiding behaviors on employees' silence and organizational deviant behaviors with the mediating role of psychological contract breach. This research is applied in terms of purpose and descriptive-surveillance in terms of nature. The statistical population of the current research includes the employees of the large taxpayer’s unit, which consists of 400 people, of which 227 people were determined as a statistical sample by simple random method and power analysis method. In order to collect information, a standard questionnaire was used and the data was analyzed by multivariate analysis based on structural equation modeling with a covariance-based approach in Amos software version 24. The research results show the confirmation of rationalized hiding on defensive silence, evasive hiding on relational silence, rationalized hiding on relational silence, evasive hiding on ineffective silence, rationalized hiding on ineffective silence and defensive silence on organizational deviant behavior, relational silence on organizational deviant behavior and Ineffectual silence on deviant organizational behavior and Also, the results of the mediation analysis show that the construct "psychological contract breach" has a mediating role for all relationships between the dimensions of knowledge-hiding behaviors and the dimensions of silence So that the said mediation process for the causal relationships between "playing dumb" and "defensive silence/ ineffective silence" is complete and partial for the rest of the relationships. In the section of the structural model, among the twenty-one proposed hypotheses, seventeen were confirmed, among which the effect of relational silence on organizational deviant behavior had the highest path coefficient (0.33).

The purpose of this research was to identify and prioritize the antecedents of lack of knowledge sharing among the employees of Rafsanjan Industrial Complex. This research is an applied research based on the nature and method of a descriptive-survey research. In this research, the factors were first identified using library studies, and then confirmed and prioritized using a questionnaire. The experts of the present research were 13 people who were randomly selected and included managers and senior employees of Rafsanjan Industrial Complex. Data was analyzed using SPSS 23 and Expert Choice software, and hierarchical process software was used to prioritize factors. The findings from the research data showed that the antecedents of not sharing knowledge are: Technological barriers, which have four sub-components, and the absence of systems are the most important sub-components affecting the lack of knowledge sharing. Organizational barriers are among other effective factors that have eleven sub-components, and the sub-component of lack of problem-finding and problem-solving is the most effective factor on lack of knowledge sharing. Management obstacles are also among the obstacles of not sharing knowledge, which includes six sub-components, and the lack of support for sharing knowledge is one of the most important factors affecting it. Individual obstacles are also among the obstacles of not sharing knowledge, which includes eleven sub-components, and mistrust is the most important sub-component affecting the lack of knowledge sharing. According to the results, it can be said that technological barriers and the lack of required infrastructure and technologies are among the most important factors affecting the lack of knowledge sharing, while individual factors have the least impact, that is, employees have the least impact on the lack of knowledge sharing.

The present research sought to extract a model from the knowledge dimension of the innovation system by examining the models and scientific literature about the role of knowledge in the innovation system to be presented in a defense organization and to discover the interactions between the components of the model. This research has been formed in the framework of the interpretative paradigm, with an applied and developmental approach, with a deductive-inductive strategy and a mixed method. The research data was collected in library and field and the sampling method was theoretical. The statistical population of this research was the scientific articles available in the research databases and were reviewed in full. In the quantitative part, the statistical population included experts in the field of innovation and university graduates. In this research, data collection tools, including the review of documents and documents, as well as the input matrix of the DEMATEL method were used in the form of a questionnaire. The research community was reviewed in the qualitative section, including specific scientific documents, using the theoretical sampling method. Also, in the quantitative part of the research community, the experts in this field were considered with the purposeful sampling method. In this research, using the meta-composite approach based on Barroso and Sandlovsky's approach, which includes seven basic steps, and the exploration of past researches, which according to the input criteria include scientific articles with a certain grade and after the year 2000, concepts are extracted and finally The components of the knowledge dimension of the innovation system were identified. These components, which were collected from 48 sources after screening the sources, were extracted in the form of 84 codes, which were placed in ten basic themes. These themes formed the knowledge dimension of the innovation system in the form of three categories of research, learning and knowledge management. In the following, by using the Dimetal method, the method of connecting the components and the interaction between them was investigated among the experts of a military organization. The validity of the research was confirmed in the qualitative part with the critical method and Cohen's kappa, and in the quantitative part by referring to experts. The results showed that the two variables "Preliminaries of learning" and "Protection of knowledge" are known as important players in the set of factors as factors that have the highest total effect and effectiveness (with values of 2.0841 and 1.5240, respectively). Also, two variables "Learning Introduction" and "Training" had the highest net impact value (deduction of impact from effectiveness) in the set of these factors, with values of 0.9726 and 0.2763, respectively. Therefore, these two factors are considered as the most stimulating factors and they need to be taken into consideration in the plans.

Understanding the importance of innovative and creative behavior of teachers in school is a vital and challenging issue for education officials and researchers, because schools, as professional learning communities, have the duty to support innovative behaviors. In fact, since schools and teachers are expected to train students who will be a creative and innovative workforce in the future, the importance of innovative behavior of teachers as agents of change and role models for students in this way is obvious. Therefore, the aim of the present study was to investigate the effect of the innovative climate on the innovative behaviors of teachers with the mediating role of knowledge sharing. The current research was applied in terms of purpose and descriptive-correlation in terms of execution. The statistical population included 3252 teachers of Kashan citythat by using Cochran's formula and stratified random sampling method 351 people were selected as a sample. In order to collect data’s, three questionnaires of innovative organizational climate (Cigel and Kaumer, 1987), knowledge sharing (Van den Hooff & De Ridder, 2004) and innovative behavior (Kanter, 1988) were used. The validity of the questionnaires was done in face and structure (confirmatory factor analysis). Through Cronbach's alpha coefficient, the reliability of the innovative climate questionnaire 0.88, innovative behavior 0.90, and knowledge sharing 0.77 estimated. Data’s analysis of the research was done using SPSS and Smart statistical software at two descriptive and inferential levels. The results showed that the mean of the innovative atmosphere (2.96) was slightly lower than the average (3), the mean of innovative behavior (3.95) was higher than the average (3) and the mean of knowledge sharing (4.11) was higher than the average (2/5). Path coefficients showed that innovative climate with (Beta=0.425, P=0.001) on innovative behavior, knowledge sharing with (Beta=0.15, P=0.002) on innovative behavior and innovative climate with (Beta=0.40, P=0.001) has a positive and significant effect on teachers' knowledge sharing, and the mediating role of knowledge sharing was confirmed in the effect of innovative climate on teachers' innovative behavior. In fact, when teachers perceive the climate of the organization as supportive of innovation, they will be more willing to share knowledge and transform tacit knowledge into explicit knowledge, and in fact, a suitable platform is provided for knowledge distribution among teachers, the exchange of information takes, and this issue is the basis and potential for the occurrence of innovative behavior.
