군사과학기술이 발전하고 안보위협이 다양화됨에 따라 해양에서의 안보환경이 변화되고 군사작전의 범위가 확대되고 있으며, 군사작전 개념도 변화하고 있다. 따라서 변화하는 해양안보환경 속에서 군사작전을 완벽하게 수행하기 위해서는 민간분야를 포함하여 다양한 요소들과 유기적인 네트워크체계가 구축되어야 한다. 본 논문은 안보환경 및 작전개념 변화에 따라 해양에서 성공적인 작전수행을 위해 네트워크체계가 어떠한 방향으로 구축되어야 하는가를 제시하였다.

The subjects of this study were 258 Korean-Chinese parent-child dyads of an elementary school in Yanbian Province, northeastern China. Research questions covered relationships among children's school adjustment and ecological factors, significance of factors within ecological levels, and direct and indirect effects in causal relationships. Results showed significant effects within each ecological level. Achievement motivation of the individual system, home environment and social support of the microsystem, and mother's job satisfaction in the exosystem had significant relationships with children's school adjustment. Mother's education and job satisfaction influenced school adjustment through home environment; the causal relationship between social support and school adjustment was mediated by achievement motivation. Personal and general factors from each ecological level were more significant than ethnic related factors in explaining children's school adjustment.

Despite the fact that school facilities are one of the most important public facilities, information about school facilities is not systematically managed. The purpose of this study was to investigate the direction of system construction to provide objective data on school facilities, which is the basic element of school facility policy. In this study, we propose a system construction method to improve the information management procedure of school facility information and school facilities, and suggest a system design direction for providing service that can be practically used.

This research intended to investigate, from an ecological perspective, significant predictors affecting school life satisfaction. The subjects were 312 students(2nd grade) of commercial high school in Kyonggido. Data collected by questionnaire survey were analyzed by SPSS Win 22.0 and descriptive statistics, correlation analysis, hierarchical linear regression, and stepwise regression were conducted. There were 21 independent variables: 8 organism variables (self-competence, interpersonal skills, internal control, mood awareness, emotional expression, empathy, emotional regulation, emotional capability), 9 microsystem variables(school variables: the relationship with teachers, school learning, classroom climate, school welfare facilities, school environment/peer variables: peer relationship/family variables: family functioning, education level of fathers, economic status), 2 mesosystem variables(parent-teacher relationship, parent-children's peer relationship), 1 exosystem variables(satisfaction with Korean educational system), 1 macrosystem variables(Korean's primal belief in educational achievement). The results are as follows; the significant variables were the relationship with teachers, satisfaction with Korean educational system, peer relationship, emotional capability, parent-teacher relationship($R^2=45.3%$); and the effect of microsystem was the strongest($R^2=35.7%$). This research is meaningful of analyzing school life satisfaction of commercial high school in terms of ecological perspective.

This study verified the effect that the ecological factor had on the smartphone addiction, and then validated the difference related to current smartphone addiction with actual state of dysfunction. To substantiate the results of this study, the 6th graders at five elementary schools located in Incheon, were surveyed and a total of 672 questionnaires were analyzed. In the results of this study, the school district as the ecological factors had a significant effect on smartphone addiction of elementary students. Through the results of analysis, we found that a smartphone addiction is not cased by the personal inclinations, but has to cooperate individual, home, school and society.

This study evaluates potential factors in various levels that affect students' intent to leave school. Those levels include individual, family, and school. After thorough review of literature on related subjects, the data from 「2021 Youth Survey on Human Right Conditions」 will be analyzed. Binary logistic regression analysis shows several results. First of all, respondents' age and sex strongly influence students' intents to leave school. Secondly, in terms of effect size, respondents' age is strongly related to the dependent variable in all models. Third, compared to those variables in individual and family levels, the effects of variables in school level are more significantly related to the intents to leave school. Finally, the significance of the effect of students' independent activities in school on the intent to leave school implies that students' voluntary and independent activities in school could decrease students' frustration in school and increase motivation to stay in school in certain ways.

As science and technology develops, it is expected that more precise and various weapons will be used in a much more complicate future battlefield environment. C4I is a system that provides the proper and necessary information to commanders and their staffs to recognize the battlefield situation by connecting and visualizing the complex battlefield environment and various weapon systems together. Commanders and staffs perform battle command training based on a computer or paper map to better utilize the C4I system and Command Post eXercise(CPX) is a process of the training. This is the way for them to improve command control and decision making skills. Analyzing of line of sight(LOS), identifying communication fringe area, deploying troop strength, and determining unit maneuver are highly restricted under the 2D based CPX. In recent years, however, three-dimensional (3D) CPX simulators have been developed to overcome these drawbacks. In response to this trend, this paper proposes a multi-user based CPX simulator using augmented reality (AR) glass, which can be used as a practical war game simulator.

The purpose of this study is to explore the environmental educational relevance of Oriental Storks and school wetland biotope, and to explore environmental education methods using them. Through the study of literature, the history encompassing the extinction and restoration of resident Oriental Storks and the utilization of school wetland biotope, were considered, and the meaning and connection of environmental education were derived. Based on this, planned an environmental education program for all elementary school students. The program consisted of a total of 17 steps reflecting the core elements of environmental education. The specific learning material of an Oriental Stork and the specific place of a wetland biotope as a school facility were linked to provide experience and practice. In conclusion, environmental education for coexistence with nature can be promoted, and the specificity and systematicity of contents can be secured.
