빅데이터는 최근 우리 사회에 다양한 분야에서 활용하고 발전하고 있는 분야이다. 정치, 경제, 사회의 각 분야에서 많은 자료를 분석하여 자료에 숨어 있는 다양한 의미를 파악하는 빅데이터 분석 기법이 자주 활용되고 있다. 하지만 교육이라는 부분에 있어서 빅데이터는 단순한 분석 등에 활용하기는 하지만 교육과정과 방향에 대한 분석은 아직 미비한 실정이다. 이에 본 연구에서는 빅데이터 분석 기법을 활용하여 중학교 정보 교과서의 핵심 개념을 파악하여 분석하고자 한다. 정보 교과서 분석을 위한 빅데이터 분석법은 텍스트 마이닝을 사용하였다. 이 프로그램을 활용하여 파악된 중학교 정보 교과서의 핵심 개념들을 통해 교과서에서 강조하고자 하는 개념을 확인할 수 있었고, 교육 분야에서도 빅데이터 활용 가능성을 확인할 수 있었다.

This study discusses special aspects of severe accident related recriticality modeling and analysis in the Advanced Neutron Source (ANS) reactor.$^{1, 2)}$ The analytical comparison of three elements core to former two elements case is conducted including evaluation of suitable nuclear cross-section sets to account for the effects of system configulation, fuel and moderator mixture temperature, material dispersion and the other thermal-hydraulics. Three elements core ANS reactor is the alternative core design which was proposed as a modified core design, with three fuel elements instead of two, that would allow operation with only 50% enriched uranium (former uranium fuel is the baseline design value of 93%) A comprehensive test matrix of calculations to evaluate the threat of a criticality event in the ANS is described. Strong dependencies still on geometry, material constituents, and thermal-hydraulic conditions are verified. Therefore, the concepts of mitigative design features are qualified.d.

Policy-based Network Management (PBNM) has been presented as a paradigm for efficient and customizable management systems. The approach chosen is based on PBNM systems, which are a promising and novel approach to network management. These systems have the potential to improve the automation of network management processes. The Internet Engineering Task Force (IETF) has also used policy concepts and provided a framework to describe the concept as the Policy Core Information Model (PCIM) and its extensions. There are policy conflicts among the policies that are defined as the policy information model and they are not easily and effectively detected and resolved. In this paper, we present the brief description of PBNM and illustrate the concepts of policy core information model and its policy implementation for a network security. Especially we describe our framework for detecting and resolving the policy conflicts for network security.

The purpose of this study is to explore the core competencies of the Fourth Industrial Revolution in the major newspaper articles of social network analysis and to examine the core competencies required by each field and target. To do this, we reviewed prior research focusing on core competency concepts and core competencies of engineering students, and analyzed 227 articles related to core competencies of the 4th Industrial Revolution, focusing on five major newspapers. Through analysis, we analyzed social network with 118 refined core competency keywords. As a result of the research, it was found that core competencies of the 4th Industrial Revolution are the degree centrality in terms 'creativity', 'problem solving ability', 'convergence ability', 'collaboration ability', 'conductivity', 'software ability', 'human literacy', 'personality' order. Also, as a result of the analysis of the ego centric network by field and target, the required core competencies of university and industry were found to be different. Through these discussions, it is necessary to restructure the core competence of engineering students in order to nurture the engineering talents necessary for the 4th Industrial Revolution.

This study clarifies the definition of and to provides guidelines on educational objectives, core concepts, and content in developing a Human Rights Education Program for families. The Delphi survey method was used to develop a Human Rights Education Program for families. As a result, a Human Rights Education Program for families was defined as education that would ensure all members of the family enjoy universal human rights without discrimination. In addition, that the prejudice and discrimination against socially marginalized would not be created within the family by learning values and attitudes that respects human rights and freedom. The objectives were to learn the merit of respecting individuals, relationships, and community. Core concepts of the program were the rights for myself and others, communicating and responsibilities and a sense of citizenship. Content included human rights, respect of oneself and others, empathetic understanding, acceptance, communication in an intimate relationship, conflict management, sharing the role of caring the family, no discrimination against the socially marginalized, and creating an inclusive community culture. This study can be used as a guideline for family human rights education based on family human rights, which is the core of family democracy.

기업의 투명성과 사회적 책임이 강조되면서, 비즈니스 보고(Business Reporting)에 특화된 XML 언어인 XBRL(extensible Business Reporting Language)의 활용도가 크게 증가하고 있다. XBRL은 기업보고 문서의 구성요소들(개념들과 이들의 구조체들)을 XSD (XML Schema Definition)로 정의한다는 점에서 기업간 전자문서 표준화와 기본적으로 동일하다. 그러나, 개념들의 유형이 특정하게 한정되어 있고, 이들 개념들을 연결하고 부가 정보를 제공하기 위한 다양한 관계 유형을 정의한다는 점에서 근본적인 차이가 있다. XBRL응용이 활성화되면서 국가적인 수준에서의 표준화와 함께 체계적으로 구성요소들을 재활용해야 할 필요성이 증대되고 있으나, 이러한 근본적 차이로 인해서 표준화와 재활용에 어려움을 겪고 있다. 이 논문에서는 UN/CEFACT의 핵심 컴포넌트 방법론을 적용하여 XBRL문서의 표준화 및 재활용이 가능하도록 하기 위하여, 문제점을 분석하고 대안을 제시한다.

Purpose : This research is aimed at developing a substantive theory related to the experience of adjustmented hemodialysis patients by identifying and analyzing the nature, process, and types of adjustment experienced by them. For this purpose, this study takes a grounded theory approach. Method : Data were collected from April, 2002 through September, 2002 through in-depth interviews and close observations of eleven hemodialysis patients who have experienced adjustment. With their consent, the interviews were recorded by audio tapes and later transcribed. Observation memos were also prepared on the subjects' behavior during the interviews. Data collection continued until saturated. The data were analyzed into concepts, subcategories, and categories with the open coding process. The axial coding was done to identify the relationships of the concepts and categories. And the selective coding was done to develop a core category, which is the central phenomenon of the hemodialysis patients who experienced adjustment. Result : This process resulted in 88 concepts, which may be grouped into 24 subcategories and 6 core categories. The 6 categories, in fact, depict the process of changes the patients experience from the sense of crisis, self-control, new life meaning, support system, coping ability, and quality of life improvement. And its core is self-control, which encompasses the dynamic stages from recognition, change attempts, belief solidification, and empowerment. Conclusion : The results of the research offer the following implications. First, research on adjustment is a formative stage in nursing, it is imperative for nursing researchers to develop them, which may be more relevant to nursing. Second, it is important to develop nursing intervention techniques that may be most effective in adjustment of hemodialysis patients and at the same time for each stage of changes taking place in adjustmented hemodialysis patients.

The capabilities of the metaverse have been demonstrated by representative examples such as Roblox, Fortnite, and Zepeto, and it can enable gaming, social networking services, and other applications. Nevertheless, research on the metaverse has been fragmented owing to conflicting definitions, core values, and characteristics. This ambiguity in metaverse conventions has hindered related research, analysis, and policy establishment. As the confusion seems to aggravate, consistent concepts should be established. Although the coronavirus disease pandemic led to a collapse in metaverse usage, it is regaining public interest since 2022. To promote the metaverse development, we structure core values based on existing research and surveys of consumer expectations. We found that consumers perceive the metaverse as a realistic virtual space and a potential economic opportunity. Hence, it seems necessary to track the extent to which the metaverse core values satisfy consumer demands. Such core values should be consistently reflected in policies and technology development.
