지식관리시스템은 기업들의 생산성을 높이기 위해 사내보유 지식을 획득, 관리하여 후속 업무 처리에 적극 활용하도록 지원하는 시스템이다. 현재 지식관리시스템들에서는 정형적 지식에 대한 추출은 잘 이루어지고 있으나, 조직원들의 암묵지에 대해서는 자발적 등록을 유도하는 보상제도 등의 방법에 의존하고 있다. 본 논문은 업무를 진행함과 동시에 조직원으로부터 지식을 의무적으로 획득할 수 있는 방법에 대해 연구하였다. 또한 지식을 온톨로지 기반으로 표현함으로써 지식을 단지 설명하는 차원의 지식베이스를 구축하는 것이 아니라 새로운 지식을 추론할 수 있는 방법을 제안하였다.

The development of information networks and computer technology has become a foundation to open up a sea of information and knowledge. The recent popularization of smart devices has been used as a tool to easily obtain the desired information and knowledge. In this paper, a knowledge-sharing system using information and social networks based on smart devices is proposed. The proposed system consists of functions of an Internet information search for user queries, accumulated knowledge, and social network response from acquaintances. An evaluation for user satisfaction was conducted to analyze the efficacy of the proposed system. According to the experiment, the knowledge-sharing system using smart device information results in significant satisfaction compared to the general information search engines.

We propose classifying the venture firms into four types of knowledge management. For this purpose, we collected questionnaire data from 101 venture firms listed in KOSDAQ, and applied a unsupervised neural network algorithm SOM to obtain four clusters representing knowledge management types-High Tech Type, Organizational Knowledge Type, Information Technology Type, and Beginner Type. Based on the results, we conclude that the venture firms listed in KOSDAQ should first know its own knowledge management type, and then apply appropriate strategies to take advantage of the knowledge management impacts on the competitiveness.

The purpose of the study is to design the ontology-based Prescription Knowledge Management System of Oriental Medicine. The study was done with the premise that the effectiveness of the system can be improved by using ontological abstractional structure based on definition of concept, attribution and relations of words related to the specific area. The system is developed with Protege-2000 by using newly developed KPML(Korean Medicine Prescription Markup Language). The results of the study provide the model of Prescription Knowledge Management System and the possibility of implementing XML-based ontology system to the semantic web environment.

The purpose of the study investigate mathematics content knowledge(MCK) of prospective teachers in differential area. 70 prospective teachers were asked to perform six questions based on Cho's MCK (2010, 2011). The results show that depending on whether they experience any teacher education program, the level of prospective teachers' mathematics content knowledge may vary. In particular, prospective teachers struggled with an unfamiliar problem situations. We also found that prospective mathematics teachers have some difficulty in solving problem about the use of mean value theorem and derivative.

IS 구성원의 직무수행에 요구되어 지는 지식이나 기술의 유형을 크게 기술적 지식/ 기술과 기업업무 지식/기술, 그리고 시스템 지식/기술로 대별될 수 있다. 이를 세분화하면 기술적 기술은 하드웨어와 소프트웨어로 기업업무 기술은 업무과정, 관리적, 사회적 기술로, 시스템 기술은 문제 해결과 개발방법의 하위 차원으로 유형화 할 수 있다. IS 구성원의 직 무 지식/기술은 직무만족과 높은 관련성을 가지고 있으며, 구성원이 지각하는 직무만족의 정도에 따라 조직몰입에는 정의 관련성을, 그리고 이직의도와는 부의 관련성을 가지게 된 다. 이는 IS 부서의 성과제고를 위한 중요한 시사점을 제시해 준다.

Simulation for product design requires a lot of causal knowledge. Hence, knowledge integration is required for obtaining a new knowledge from existing knowledge. For example, a user requests knowledge for the heating cup. However, the knowledge base only has knowledge for heating and cup, not heating cup. At his situation, knowledge integration can generate a new heating cup knowledge from existing heating and cup knowledge. Therefore, the user can obtain the knowledge for heating cup. Hence, this study aims to propose a novel knowledge integration method for product design.

This study aimed to investigate technological pedagogical and content knowledge(TPACK) model, and to apply this model to preservice education. To perform this study, TPACK survey instrument was distributed to 142 preservice teachers who took technology integration course. The result showed that technology and content knowledge improved significantly, and pedagogical and pedagogical content knowledge did not show meaningful differences among 7 sub-categories. Based on the result of this study, we discussed the improvement of technological and content knowledge, and pedagogical knowledge. Also, we suggested that (preservice) teacher education should consider the combination of technological, pedagogical, and content knowledge in Korea.

The purpose of this study was to investigate addition strategies of the 1st year elementary school students compared to the strategies recommended by the 7th national curriculum. We used interviewed children's worksheets to analyze the children's strategies. The results of the study showed that the formal strategies the textbook recommended and the children's strategies were so different. Teachers need to articulately comment two strategies when they teach mathematics in the classrooms.

This study explores knowledge structures of science and technology disciplines using a cocitation analysis of journal subject categories with the publication data of a science & technology oriented university in Korea. References cited in the articles published by the faculty of the university were analyzed to produce MDS maps and network centralities. For the whole university research domain, six clusters were created including clusters of Biology related subjects, Medicine related subjects, Chemistry plus Engineering subjects, and multidisciplinary sciences plus other subjects of multidisciplinary nature. It was found that subjects of multidisciplinary nature and Biology related subjects function as central nodes in knowledge communication network in science and technology. Same analysis procedure was applied to two natural science disciplines and another two engineering disciplines to present knowledge structures of the departmental research domains.
