신학진 기전여자대학 2000 論文集 Vol.20 No.-
Recently, web-based instruction or cyber education has become a hot issue in computer science research community. The computer industry is also interested in the web-based instruction. Consequently, we witnessed several well designed packages in this arena. In the paper, we extract common and practical factors from not only theoretical approaches but also industrial approaches to this subject, so that utilize the factors to design and implement a web-based instruction program. For this purpose, first, we categorize factors in terms of time, size, and location of class. Secondly, the solutions for different ways of running classroom are reviewed. In this stage, we survey the components related to web-based self study and web-based on-demand teaming. Finally, for the completion, we study the environments for the real-time online education. In conclusion, we forsee the future of cyber education.

의미적 개념(Semantic Concepts)을 이용한 지식 표현의 형식 규정에 관한 소고
신학진 기전여자대학 1993 論文集 Vol.13 No.-
Currently, there are many researches working on various components for knowledge base system(KBS). Integration of such components is troublesome for several reasons, not the least of which is due to the different terminologies and knoweldge representation formalisms which are used by the various components. A possible solution to this problem is to identify a commonly used set of semantic concepts and then employ this set of concepts to characterize the type of knowledge which is processed by the various components. Choice of an appropriate set of semantic concepts should be based on pragmatic criteria rather than philosophical argument, otherwise it is likely that agreement will be reached on what concepts to inculude. we present a version of concepts which was chosen intuitively. We illustrate how this set might be refined by application to example components of KBSs.

객체-관계기반 매핑을 이용한 XML DTD와 관계형 데이터베이스 스키마 생성
신학진 기전여자대학 2002 論文集 Vol.22 No.-
As eXtensible Markup Language becomes the data standard for e-business, the amount of XML data being exchanged grows exponentially. While enterprises may initially conceive of those XML documents and messages as transitory images of data in a legacy infrastructure, a requirement to store that XML data for fast and accurate retrieval is likely. In the paper, we describe the relevant concepts to store XML data into and retrieve them from database. Using the relevant techniques, we fabricate an algorithm to covert DTD to database schema and vice versa. Finally, we brief the current problems and the future studies.

하이퍼공간에서 방향 상실 문제를 극복하기 위한 가시화 맵의 사용에 관한 소고
신학진 기전여자대학 1994 論文集 Vol.14 No.-
One of the major usability problems with hypertext is the user's risk of disorientation while navigating the information space. Our paradigm is based on the idea of visualization of 'points of interest' which are defined by users. Each point of interest is defined by a number of key terms and a display position. Nodes of hypertext are positioned in the display of points of interest based on the frequency count of word matches in the nodes to key terms in the points of interest. Once visual map is on the display, users can choose one of the nodes and review the contents of the node. By this way, the users can actively decide what they want to see and where to go in hyperspace, so that not only they overcome the disorientation problem, but also study their own interests further.

As GML (Geographic Markup Language) becomes the data standard for geographic information system, the amount of GML data being exchanged grows exponentially. While enterprises may initially conceive of those GML documents and messages as transitory images of data in a legacy infrastructure, a requirement to store that GML data for fast and accurate retrieval is likely. In the paper, we describe the relevant concepts to store GML data into and retrieve them from database, especially, RDB ( Relational Database ). Using the relevant techniques, we design an architecture of a GML-RDB mapping system and fabricate an algorithm to covert GML schema to relational database schema and vice versa. Finally, we brief the current problems and the future studies.

Internet computing will enable large-scale aggregation and sharing of computational data and other resources across institutional boundaries. For this. the concept of GRID is coined. The Grid will not only enable sharing of documents and MP3 files, but also connect PCs with sensors, telescopes and tidal-wave simulators. The Grid, as the next-generation Internet is called, will give researchers intelligent access to information and analysis tools as well as to raw computing power. In this paper, we survey the concept of the GRID and its architecture. Based on the architecture, we study the current issues on the concept and the applications of the GRID. Finally, we conclude the potential and the future of the GRID.

노인의 차별경험이 자아통합감을 매개로 삶의 질에 미치는 영향
신학진 한국노년학회 2010 한국노년학 Vol.30 No.2
In this study, we investigated the effects of ageism experience of the elderly on ego integrity and quality of life, where the ego integrity is mediated between ageism experience and quality of life. To investigate the cause and effect of factors, we purposively collected 297 samples from a senior welfare center in Jeonju and exploited reliability analysis, confirmatory factor analysis and SEM(Structural Equation Modeling) for 282 cases excluding some cases with missing values. As the results, first, we confirmed the increase of ageism experience decreased the ego integrity. Second, the increase of ageism experience degraded the quality of life. Third, the ego integrity positively influenced the quality of life. Fourth, the ageism experience has effects directly as well as indirectly on the quality life. Based on the results, we could suggest that in the aged society combating law, policy, and propaganda against ageism would significantly influence on the elderly's ego integrity and quality of life. 본 연구는 사회적 지지의 반대 개념인 노인차별경험이 자아통합감에 부정적 영향을 미칠 것이며, 또한 노인의 삶의 질에도 부정적 영향을 미칠 것이라는 점을 검증하고자 했다. 연구를 위해서 전주시에 소재한 노인복지관에서 실시하는 노인 일자리사업에 참여하는 노인 중에서 응답자를 편의 추출하였다. 회수된 설문지 294케이스 중에 결측값이나 불성실한 응답을 제외하고 282케이스가 분석대상이 되었다. 신뢰도분석, 확인요인분석, 요인간의 관계를 확인하기 위해서 구조방정식 모형분석(SEM: Structural Equation Modeling)등을 실시하였다. 주요 결과는, 첫째, 노인차별경험은 자아통합감에 부정적인 영향을 미치는 것으로 나타났다. 둘째, 노인차별경험이 많을수록 노인의 삶의 질은 낮아진다고 분석되었다. 셋째, 노인의 자아통합감이 클수록 노인의 삶의 질은 높아진다고 검증되었다. 넷째, 노인의 노인차별경험은 삶의 질에 영향을 직접적으로 미칠 뿐 아니라 자아통합감을 매개로 삶의 질에 간접적인 영향을 주는 것으로 해석되었다. 연구를 통해서 고령사회를 대비하여 노인차별에 대응하는 법, 정책, 교육 등을 마련하고 실천하는 것이 노인의 삶의 질을 개선할 수 있음을 제시했다.
