Nam(2008a) suggested that the role of teacher for helping students to learn mathematical structures should be the manifestor of tacit knowledge. But there have been lack of researches on embodying the manifestation of tacit knowledge. This study embodies the manifestation of tacit knowledge by showing that exemplification is one way of manifestation of tacit knowledge in terms of goal, contents, and method. First, the goal of the manifestation of tacit knowledge through exemplification is helping students to learn mathematical structures. Second, the manifestation of tacit knowledge through exemplification intends to teach students mathematical structures in the tacit dimension by perceiving invariance in the midst of change. Third, the manifestation of tacit knowledge through exemplification intends to teach students mathematical structures in the tacit dimension by constructing explicit knowledge creatively, reflection on constructive activity and social interaction. In conclusion, exemplification could be seen one way of embodying the manifestation of tacit knowledge in terms of goal, contents, and method.

The purposes of the study are to describe the feature of the program components, and to identify their changes in the process of designing the social work programs in the community service agencies in Korea. In order to achieve these purposes, the researchers constructed an analytical framework including 24 program components derived from the related literatures. Data was collected by questionnaires answered by the social workers who were in charge of the program development and implementation. Descriptive statistics analysis and factor analysis were applied to exam the features of the program components in 195 social service programs developed by the funds from the Community Chest of Korea and a private funding foundation. As the result of the analysis, the three noticeable features are found; (1) the agencies have very actively involved in the designing work in the process of developing practice guideline, however they have less involved in the designing work in the process of implementing program; (2) program components which are low level in design activities are intervention models, staff education, and practical ethics; (3) 8 categories of components derived from the theoretical perspective are reduced to 6 categories in the process for developing practice guidelines, finally to 4 categories in the process for implementing the programs. The implications of major findings were discussed in academic and practical perspectives in Korea, including future research works in the area.

The purpose of this study was to survey collaborate learning in early childhood settings in Korea. Specifically, the study examined whether the realities of and the teachers' perception on collaborative learning would differ in terms of the teachers' belief on constructivism. To achieve this purpose, 210 teachers of kindergartens and daycare centers in Busan completed a questionnaire developed by the authors. The teachers' belief on constructivism was rated as high, medium, and low. The ${\chi}^2$-test, one-way analysis of variance, and the Scheffe test were used to analyze the teachers' interest on and practice level of collaborate learning. As a result of this analysis, the authors observed several significant differences in the realities of and the teachers' perception on collaborative learning in terms of the teachers' belief on constructivism. We discussed the results and provided practical implications for teacher training.

The purpose of this study was to analyze the effect of infographic instruction to promote the use of the scientific model in the 'lens' unit of elementary science textbooks. The participants were $6^{th}$ grade students(n=53) of G elementary school in G city, Gyeongsangnam-do. For this study, the lesson plan of the 'lens' unit consisted of three steps as investigation of students' prior concept about the lens, scientific model construction activity, and infographic construction activity. We then analyzed the results of this study from three perspectives: the scientific concept, scientific model, and infographic. Before the lesson, students focused on the external shape and material of the lens in prior concept of it. However, after the scientific model construction activity and infographic construction activity, students' scientific concept about the lens improved in the categories of features of lens, features of glasses, light path, and applications of the lens. In terms of the scientific model, use of type and frequency of scientific model increased more in the infographic construction activity than the scientific construction model activity. Also, in terms of infographic, the two infographic types as function based infographic and connection based infographic used more than non-infographic in the infographic construction activity. Also, the frequency of Gestal theory's visual perception increased more in the infographic construction activity than the scientific model construction activity.

This study examined the activities of Community of Practice (CoP) of research data curators, including their community building and maintenance activities, by using activity theory as its main theoretical framework. The study used an embedded multiple-case study design for exploring the activities of three CoP of research data curators. The case study design used document analysis and semi-structured interviews to collect data. Besides the community building and maintenance activities, other activities were performed in the CoP of research data curators, which could be largely divided into curation activities, education activities, and communication activities. Membership was largely divided into institutional membership and individual membership, and the motives for members to join and contribute to the CoP vary from extrinsic to intrinsic motivations. Finally, we identified and categorized challenges and success indicators for CoP of research data curators as perceived by participants. In particular, we identified three types of challenges or contradictions the communities faced and 14 perceived indicators of success. This study informs the practice of research data curation by providing a knowledge base for building and maintaining a CoP of research data curators.

This study was carried out for the purpose of inquiring into the effect of composition and security activities for information security architecture on information asset protection and organizational performance in terms of general information security. This study made a survey on 300 workers in the government, public institutions and private companies, which it showed that management factors of risk identification and risk analysis, in general, have an usefulness to composition and security activities for information security architecture to prevent inside information leakage. And the understanding and training factors of IT architecture and its component were rejected, requiring the limited composition and security activities for information security architecture. In other words, from the reality, which most institutions and organizations are introducing and operating the information security architecture, and restrictively carrying out the training in this, the training for a new understanding of architecture and its component as an independent variable made so much importance, or it did not greatly contribute to the control or management activities for information security as the generalized process, but strict security activities through the generalization of risk identification and risk analysis management had a so much big effect on the significant organizational performance.

영재교육의 이론적 근거를 제시한 연구물이 국내에는 그다지 많지 않다. 뿐만 아니라 지금 한국과학재단에서 지원하고 있는 전국의 9개 대학 과학영재교육센터 역시 실천적인 차원의 활동을 벗어나지 못하고 있다. 외국의 대학부설 연구소들이 30년 이상 이와 같은 연구와 서비스를 지속적으로 실천해오고 있는 사례들을 우리는 쉽게 찾을 수 있다는 점을 거울 삼아 모처럼 마련된 국가적 차원의 지원을 토대로 그 바람직한 실천과 연구를 위한 방안을 다음과 같이 제시해본다. 첫째, 질적 연구의 집적에 힘써야 한다. 영재교육이라는 특수한 상황을 전제로 할 때는 더구나 그렇듯이 일반화를 전제로 한 양적 연구보다는, 사례연구와 같은 질적 연구물들의 집적에 노력을 아끼지 말아야할 것이다. 둘째, 교수-학습 활동은 활동이론과 구성주의 이론의 적절한 조화가 요망된다. 구성주의 이론에 입각한 교수-학습 활동의 모습을 단적으로 말하자면, 학습자 자신이 주어진 문제 상황에서의 탐구를 통하여, ‘구체적인 것에서 추상적인 것으로’ 나아가 스스로 지식을 구성하는 것이다. 그러나, 활동이론에 입각한 교수-학습 활동의 요지는 활동은 정말로 전형적인 활동에 국한하고 나머지는 교사의 설명에 의해 학습자들이 ‘추상적인 것에서 구체적인 것으로의 소급’이 가능하도록 하는 것이다. 완전히 정반대의 주장을 하는 것 같으면서도 일면 그 타당성들을 갖고 있는 것으로 볼 수 있다. 셋째, 학제적 ${\cdot}$ 통합적 연구가 절실하다. 연구의 측면에서 수학반 아동과 과학반 아동들의 활동상의 차이점이나 유사점 등에 대한 질적 연구를 시도해보는 것은 매우 의미있는 일이 될 것이다.
