Intelligent Tutoring System(ITS), which offers individualized learning environment that consider many learners' variable, is realized by the effective alternative to take the place of domain expert. Accordingly, research on Learning Companion System(LC) is currently noticing. However, to develop LCS which applies effective interaction, it is necessary to combine several LCs, and personalized knowledge base have to be made first. Therefore, in this paper, we propose the 'Knowledge Base Object Medel', which is based on connectionist' in cognition structure, represents learner's knowledge to self-learnig object, and grows adaptive object by proprietor, verify the validity. This model lays the groundwork for design of personalized knowledge base, offers clue to development of adaptive ITS using knowledge base object.

The purpose of this study was to analyze teachers' pedagogical content knowledge on probability. Teachers' pedagogical content knowledge on probability was analyzed in detail into 2 categories: (a) subject matter knowledge, (b) knowledge of students' understanding and misunderstanding. The results showed, in terms of the subject matter knowledge, that the teachers have some probability misconception. And, it showed, in the point of the knowledge of students' understanding, they could not explain why students have difficulties to solve some tasks with regard to probability. This study raised several implications for teachers' professional development for effective mathematics instruction.

A blockchain based platform can ensure data integrity, reliability, and security by applying distributed processing and encryption technology for transaction records. In the existing knowledge sharing platform, the created knowledge could not be shared or utilized sufficiently due to information asymmetry and centralization. However little research has been done so far on this area. In this study, we will examine case studies and development potentials for blockchain based knowledge sharing platforms based on previous studies of blockchain technology, token economy, knowledge sharing, motivation theory, and social exchange theory. Blockchain based platforms can contribute to the activation of knowledge sharing, by resolving information asymmetry, simplifying unnecessary work procedures through unified knowledge sharing flow and excluded centralization of authority by decentralization, and strengthening access and utilization of the knowledge produced by the platform.

The purpose of this study is to examine factors affecting an individual's acceptance of mobile banking, which is a typical example of smartphone based self-service. We derive three personal traits(positive technology readiness, negative technology readiness and individual's expertise) as antecedent variables that affect intention to use mobile banking from previous studies, and adopt a technology readiness and acceptance model(TRAM) to investigate factors that determine an individual's intention to use mobile banking. TRAM, which integrates technology readiness index(TRI) into the technology acceptance model (TAM) in the context of consumer adoption of e-service systems, is adopted to examine personal traits influencing on the factors forming the attitude of mobile banking. The new findings of this study are as follows. First, individual's expertise and positive technology readiness(ptr) have significant effect on both perceived usefulness and perceived easy of use. However, negative technology readiness(ntr) has significant effect on only perceived easy of use.

본 논문에서는 컴퓨터 비전의 한 분야인 영상처리에 의한 물체인식을 위한 선행연구로써, 차량번호판 인식 시스템을 구현하기 위한 연구의 한 부분인 차량 번호판의 일련번호부분을 추출하는 방법을 기술한다. 이진화된 전체 차량 이미지의 일련번호영역을 추출하기 위해 레이블링기법과 번호판 일련번호의 특성 등 선행지식을 이용하여 번호판의 각 일련번호를 찾아서 분할하고 추출하는 알고리즘을 제안한다. 번호판영역을 찾는 동시에 분할하고 추출해 줌으로써 복잡한 여러 알고리즘을 사용하지 않고도 비교적 정확히 번호판의 일련번호를 추출할 수 있고, 속도면에서도 상당히 우수한 결과를 보여준다.

As the Chinese franchise industry grows rapidly, efforts to find a source of competitive advantage continue to be made. Establishing a knowledge transfer system is important in the franchise industry as a source of competitive advantage. However, research in China was insufficient. This study is to explore factors and consequential factors for establishing a knowledge transfer system in the franchise industry. As a result of this study, first, it was found that not only human assets but also system assets are important for the management of knowledge transfer systems in China. Therefore, investment in system assets must proceed first. In addition, it could be seen that the management of the knowledge transfer system, human assets, and system assets affect the satisfaction of the franchise's transaction relationship and consequently improve franchise performance.

The world is in the great change by the digital revolution and is changing fast to knowledge-based society beyond information society. That is to say, Knowledge is the most powerful source of competitiveness. This change of environment needs new paradigm in design. As of today, There is need to study systematically and approach practically about knowledge management. So that, we are intend to reconstruct theoretical system from design-oriented viewpoint and propose knowledge-creation paradigm through the importing technique of knowledge management into design. This study is to develop theoretical frame work of knowledge management in design as a basic study on the implementation of knowledge management for design. By the method of study for this, It was studied literature and precedent. Further more, proposed the appropriate direction of knowledge management implementation in design. Also, It was composed knowledge management system of the infra system, information system, decision-making support system and knowledge competency. Finally, The technical feature of knowledge management system was analyzed from a information technology point of view.

Through the study of precedent researches, this study classified the influential factors of knowledge sharing intention into the support of CEO, self-worth, trust, and incentive. Then, this study conducted a survey among the workers, who are in maritime and port sectors, to illuminate how the forementioned variables influence on the knowledge sharing intention and the usage of knowledge management system The analysis of the result illustrated that the support of CEO, self-worth, trust appeared to be the influential factors of knowledge sharing intention, and that incentive and the knowledge sharing intention appeared to influence the usage of knowledge management system. This study aims to contribute to proposing a successful forthcoming implementation of a knowledge management system, by suggesting the influential factors to increase its usage to the maritime and port organizations planning to implement it before they actually installs it.

This study focused on the role of active knowledge seeking (knowledge browsing and knowledge searching) in the context of virtual community of interest. Knowledge seeking is rarely studied as an antecedent in knowledge management (KM) research. Active knowledge seeking is considered as antecedents of sense of virtual community which mediates to knowledge sharing intention and virtual community promotion. Research hypotheses are tested by applying structure equation modeling with survey data from virtual community members in South Korea. Active knowledge seeking behavior was found to be the strong predictor of sense of virtual community, which, in turn, positively affects knowledge sharing intention and virtual community promotion. Implication to practitioners is to understand and accommodate the members' knowledge seeking efforts, who are potential contributors and promoters of the virtual community. Knowledge seeking, knowledge sharing and promoting virtual community are more of human activities than technology and this study extends the understanding of such human activities. By providing a mechanism of how knowledge seeking and sharing could work harmoniously, a virtuous circle with win-win situation could be achieved in virtual communities.
