  • 최근에는 정보와 지식의 교환을 위한 시맨틱 웹 구축의 연구가 활발해 지고 있다. 동영상 콘텐츠를 시맨틱 웹상에서 지식으로 활용하기 위해서는 의미적 검색이 선행 되어야 하는데 현재는 동영상 콘텐츠의 메타데이터와 키워드의 일치성 판단에 의한 검색이 주를 이루고 있다. 본 논문에서는 집단 지성을 사용하여 동영상 콘텐츠의 의미적 검색 및 활용이 용이하도록 사용자 참여 정보를 확대하고, 의미적 요소인 유용성 수치와 히스토리 데이터를 추가한 온톨로지 구축 방법을 제안한다. 제안한 온톨로지 스키마를 활용하면, 시맨틱 웹상에서 동영상 콘텐츠의 의미적 검색 시 기존 검색 방법 보다 재현율이 높으며, 각종 동영상 콘텐츠를 지식으로 활용 가능하게 한다.

  • A knowledge map, a taxonomy of knowledge repositories, must have capabilities supporting and enhancing knowledge user's activity to search and select proper knowledge for problem-solving. Conventional knowledge maps, however, have been hierarchically categorized, and could not support such activity that must coincide with the user's cognitive process for knowledge utilization. This paper, therefore, aims to verify and develop a methodology to build a networked knowledge map that can support user's activity to search and retrieve proper knowledge based on the referential navigation between content-relevant knowledge. This paper deploys keywords as the semantic information between knowledge, because they can represent the overall contents of a given document, and because they can play the role of semantic information on the link between related documents. By aggregating links between documents, a document network can be formulated: a keyword-based networked knowledge map can be finally built. Domain expert-based validation test was also conducted on a networked knowledge map of 50 research papers, which confirmed the performance of the proposed methodology to be outstanding with respect to the precision and recall.

  • This study focused on the design and development of contents using Unplugged CS method to learn computer science knowledge. With the strengthening of software education, all universities students including elementary and junior high school students are demanding knowledge of computer science centered on the computational thinking. We have developed educational contents using unplugged computing method as a way to effectively learn the concept of computer science. First, we analyze the related research of Unplugged CS theory and investigate the educational method accordingly. And we divided the areas of computer science and selected learning concepts in each area. The contents of learning were divided into basic and intermediate classes considering the level of the learner. The subject of learning contents was selected evenly in the area of computer science and it consisted of 16 basic subjects and 16 intermediate subjects based on concepts that are important in each field. In order to confirm the validity of the Unplugged CS learning topic and the development contents for computer science, we conducted expert reviews and content validity tests. As a result of the validity test, the validity of the learning topic and area selection was found to be more than .92 for the CVI value and the validity of the 32 subject learning contents was over .935 in basic level and .925 in intermediate level for the CVI values. Based on the design contents, we developed digital contents for online learning and put them in the system. We expect that this study will contribute to the understanding of computer science for all, including elementary and junior-high school students as well as students at software - oriented universities, and contribute to the spread of software education.

  • Knowledge creation and management are regarded as critical success factors for an organization's survival in the knowledge era. As a process of knowledge acquisition and sharing, organizational learning mechanisms (OLMs) guide the learning function of organizations represented by its different learning activities. We examined a variety of learning processes that constitute OLMs. In this study, we aimed to capture the process and framework of OLMs and knowledge sharing and acquisition. Factors facilitating OLMs were investigated at three levels: individual, group, and organizational. The concept of an OLM has received some attention in the field of organizational learning, however, the relationship among the factors generating OLMs has not been empirically tested. As part of the ongoing discussion, we attempted a systemic approach for OLMs. OLMs can be represented by factors that are inherent to the organization's system; therefore, prior to empirically testing the OLM generating factor(s), evaluation of its organizational integration is required to determine effective treatment of each factor. Thus, we developed a framework to manage knowledge and proposed a method to numerically evaluate factors influencing the OLMs. Specifically, composite importance (CI) of the Decision-Making Trial and Evaluation Laboratory (DEMATEL) method was applied to explore the interaction effect of these factors based on systemic approach. The augmented matrix thus generated is expected to serve as a stochastic matrix of an absorbing Markov chain.

  • Purpose: This study attempted to describe hospital nurses' pre-diabetes knowledge, performance and expectation of patient. Methods: The total of 204 hospital nurses were administered the questionnaires. The questionnaire comprises general background information (including sex, age, religion, education and career), ten researcher-generated questions regarding knowledge about pre-diabetes, performance of patient education (including how many people encounter in workplace, how often teaching, how many minutes required to teach and course contents) and expectation (including need improvement of teaching, barrier to education and desirable course contents and teaching methods) Results: The average score of hospital nurses' pre-diabetes knowledge was as low as 0.82 (82% correctness). On comparison of the knowledge levels among ten pre-diabetes knowledge dimensions, the highest score was 0.95 for necessary of medical check-up. The lowest score was 0.57 for complication can rarely happen. Significant correlations were observed for education, career and knowledge regarding pre-diabetes. Moreover, 49.5% of the nurses did not instruct patients about pre-diabetes, 24.5% taught prevention skills to a third of the pre-diabetes patients they encountered, and 61.2% nurses disseminated information under 5 minutes. Improvement was necessary for 78 nurses (75.8%). Conclusion: Pre-diabetes awareness among nurses is necessary.
