The general aspects for the future warfare shows that the concept of firepower and maneuver centric warfare has been replacing with that of information and knowledge centric warfare. Thus, some developed countries are now trying to establish the information systems to perform intelligent warfare and innovate defense operations. The C4I(Command, Control, Communication, Computers and Intelligence for the Warrior) systems make it possible to do modern and systematic war operations. The basic idea of this study is to investigate how TAM(Technology Acceptance Model) can explain the acceptance behavior in military organizations. Because TAM is inadequate in explaining the acceptance processes forcomplex technologies and strict organizations, a revised research model based upon TAM was developed in order to assess the usage of the C4I system. The purpose of this study is to investigate factors affecting the usage of C4I in the Korean Army. The research model, based upon TAM, was extended through a belief construct such as self-efficacy as one of mediating variables. The self-efficacy has been used as a mediating variable for technology acceptance, and the variable was included in the research model. The external variables were selected on the basis of previous research. The external variables can be classified into following: 1) technological, 2) organizational, and 3) environmental factors on the basis of TOE(Technology-Organization-Environment) framework. The technological factor includes the information quality and the task-technology fitness. The organizational factor includes the influence of senior colleagues. The environmental factor includes the education/train data. The external variables are considered very important for explaining the behavior patterns of information technology or systems. A structured questionnaire was developed and administrated to those who were using the C4I system. Total 329 data were used for statistical data analyses. A confirmatory factor analysis and structured equation model were used as main statistical methods. Model fitness Indexes for measurement and structured models were verified before all 18 hypotheses were tested. This study shows that the perceived usefulness and the self-efficacy played their roles more than the perceived ease of use did in TAM. In military organizations, the perceived usefulness showed its mediating effects between external variables and dependent variable, but the perceived ease of use did not. These results imply that the perceived usefulness can explain the acceptance processes better than the perceived ease of use in the army. The self-efficacy was also used as one of the three mediating variables, and showed its mediating effects in explaining the acceptance processes. Such results also show that the self-efficacy can be selected as one possible belief construct in TAM. The perceived usefulness was influenced by such factors as senior colleagues, the information quality, and the task-technology fitness. The self-efficacy was affected by education/train and task-technology fitness. The actual usage of C4I was influenced not by the perceived ease of use but by the perceived usefulness and selfefficacy. This study suggests the followings: (1) An extended TAM can be applied to such strict organizations as the army; (2) Three mediation variables are included in the research model and tested at real situations; and (3) Several other implications are discussed.

Traditionally, self-efficacy, burnout and engagement are defined as work related states of mind, and formally speaking, students are not employees. But, we assume that from a psychological perspective, student core activities can be considered work. Therefore, based on SCT(social cognitive theory), we examine the mediating role of self-efficacy in the prediction of student burnout and engagement, and also the mediation of burnout and engagement between self-efficacy and performance(GPA). There is no research to date wether there would be mediating role of these variables between past success and performance. These effects were analysed in the context of mediating role of the variables in a university in a sample of 438 students. This study utilized a convenience sample drawn from various major scholar area. Results of structural equation modeling analyses were consist with a full mediation model in which academic past success predicts self-efficacy, which in turn, predicts student burnout and engagement. Also our proposed model showed that burnout and engagement are partial or full mediating variables between self-efficacy and performance. Our study's findings provide evidence that engagement fully accounted for the relationship between self-efficacy and performance, and burnout partially explained the relationships. These findings aligns with the general theorizing supported by JD-R model and SCT(social cognitive theory). More specifically, it builds on the JD-R literature as it tests one of the proposed mechanisms in the relationship between job resources and work engagement. Implications of study are discussed, together with limitations and suggestions for future research.

This study investigate the mediating effects of academic self-efficacy on the relationship between academic stress and academic burnout of Korean adolescents. A survey was conducted using a convenient sample drawn from 850 students from nine junior high schools in Kunggi-do Province. Data were analyzed using SAS package program. The results show that many students were dissatisfied with their own academic performance. There was a significant positive relationship between academic stress and academic burnout. In particular, academic performance and studying had a significant interaction effect on academic stress. Academic self-efficacy had negative effects on academic stress and academic burnout. Academic self-efficacy partly mediated the relationship between academic stress and academic burnout. These results suggest that improving academic self-efficacy is crucial for preventing and reducing symptoms of academic stress and academic burnout. In this regard, continuous social support and efforts are needed to develop instructional strategies and educational programs that can improve the academic self-efficacy of adolescents.

Objectives: The purpose of this study was to find out the relationship between academic burn out and the quality of life of college students of health and medical science, and to examine the mediating effects of self-efficacy on the relationship between them. Methods: The data of 379 college students of health and medical science in the Department of Korean Medicine and Nursing located in A and D cities were collected from March to July 2018, and were analyzed using SPSS 24.0 Statistics Program. Results: There was no mediating effect of self-efficacy on the Physical Component Score(PCS), which indicates the physical health index of quality of life in relation to academic exhaustion and quality of life of university students. However, the Mental Component Score(MCS), which indicates the mental health index, had a significant effect on the parameter of self-efficacy (β = .382, p <.001). Although the β value for the school exhaustion and MCS decreased from -.382 to -.209, the effect remains significant (β=-.209, p<.001). Conclusions: It is considered that the development and the application of a self-efficacy enhancement program is necessary to improve of self-efficacy and reduce academic burn out of college students of health and medical science.
