  • This study is a qualitative study that analyzes the achievements and tasks of the cluster curriculum through the experiences of high school students who participated in the health cluster curriculum. As a result of the study, topics such as "Best Choice in a Competitive Environment," "Change in Health Perception," "Desire to Experience Various Health Worlds," "Limits in Non-regular Curriculum Operation," and "Feel Good Imagination" were derived. Through this study, students who participated in the cluster curriculum changed their perception of health positively, and confidence in career setting and career decision-making was improved through acquiring information on health care. However, supplementing the curriculum content in the specialized fields of health care, including classes and practice, was found to be a task to be improved. It is suggested that policy alternatives for career education should be developed by sharing the achievements and tasks raised in this study.

  • MPEG Immersive Video (MIV) 표준화 기술은 다시점 영상 부호화 시 비디오 코덱의 부담을 최소화하기 위해 각 시점 영상의 차분 정보만을 표현하는 처리 기술을 바탕으로 하고 있다. 본 논문에서는 시점 간 중복성 제거를 진행하는 과정인 프루닝(pruning) 과정에서 복잡도 절감을 위해 병렬처리에 용이하도록 구성되는 프루닝 클러스터 그래프에 대해 서술하고, 각 클러스터 그래프 별 구성 전략에 따른 성능 분석을 진행한다. 클러스터 그래프 내에서 중복성 제거를 진행하지 않고 완전한 정보를 보존하는 바탕 시점(basic view)의 개수가 적게 포함될수록 처리할 전체 픽셀 화소율(pixel rate)은 감소하지만, 복원 화질 역시 감소하며 프루닝 복잡도는 증가하는 경향을 보인다. 실험 결과를 통해 프루닝 클러스터 그래프 구성에 따른 트레이드오프를 탐색하고, 최적화된 그래프 구성 전략에 따라 몰입형 비디오의 효율적인 전송이 가능함을 보인다.

  • The purpose of the study was to examine the vocational educational system of Egypt, focusing on the effectiveness of the three consecutive cycle-based curriculum and integrated technical education clusters (ITECs) in order to suggest some implications for innovating the current vocational education system of Korea. The vocational education system of Egypt is similar to that of Korea, in terms of general education to go to university and vocational education to go to labor market. However, the Egyptian system is different from the system of Korea in light of the three consecutive cycle-based curriculum that links secondary vocational education, vocational education of college level, and advanced technical and vocational education. In addition, the Egyptian system has adopted the "cluster" approach which integrates technical secondary school, intermediate technical college, and advanced technical college around one physical area so as to promote vocational education in collaboration with regional industries and to guarantee education quality. In the last part, some potential implications were suggested for upgrading the quality of vocational education of Korea based upon the benchmark results of the Egyptian vocational education system and career development of students.

  • 교육데이터마이닝은 다양한 교육 환경에서 생성되는 막대한 양의 데이터를 활용하여 학습자들의 학습 유형, 학습 진도를 분석, 예측하고 교육 성취를 효과적으로 향상시키는 것을 목적으로 한다. 효과적인 교육데이터마이닝 결과를 얻기 위해서는 교육데이터에 대한 정제 과정이 필요하며 DBSCAN 클러스터링을 통해 교육데이터에 포함된 노이즈 데이터를 제거하고 생성된 각 클러스터에서 동일한 비율로 데이터를 추출함으로써 편향되지 않은 표본 데이터를 생성할 수 있다. 하지만 DBSCAN은 두 개의 전역 매개변수에 의해 다양한 밀도분포를 가지는 클러스터를 생성할 수 없다는 문제점이 있으며 이는 교육 데이터를 정제함에 있어 치명적인 문제점이 될 수 있다. 본 논문에서는 DBSCAN의 문제점을 개선하고 클러스터링 정확도를 향상시키기 위해 고정된 매개변수를 사용하지 않고 각 밀도분포에 대해 최적의 입력 매개변수를 결정함으로써 다양한 밀도분포를 가지는 클러스터들을 효과적으로 생성하는 C-DBSCAN을 제안한다.

  • The purpose of this study was to suggest qualitative improvement through various student-centered curriculum's teaching experiences focusing on physical education. For this, class diaries, memos, lesson plans, student reviews, and videos for the past four years (2017-2020) were collected and analyzed from four high schools in kyonggi-do, and six students were interviewed. The common features between each student-centered curriculum were to have many students with the purpose of entrance examination and with concern about time conflicts between class and their dinner. In contrast, the differences between each student-centered curriculum were the required level of writing lesson plan, the level of interest and role of a class supervisor, and educational expected effect of students under a given condition. In summary, pre-education experience should be required and class activity support and various evaluation methods should be also needed.

  • As the topics of general education in universities become more diverse, it is not an easy task to identify the topics of general education courses. This study aims to identify and visualize the topics of A university's general education courses using informetric analysis methods. 214 syllabi were collected and titles, course introduction, goals, and weekly plans were analyzed. 278 topic words were extracted from the data set and grouped into 8 clusters. In the network analysis, topic clusters were divided into two areas, personal and social. Personal area has 14 sub-topic clusters and social area has 11 sub-topic clusters. In personal area, 'language', 'science', and 'personality' were major topic clusters. In social area, 'multi-culture' cluster was the core cluster with connected to four other clusters. The topic network generated in this study can be used for the university and the university library to enhance general education or to develop collections for general education.

  • The cultural cluster in Chuncheon was initiated in the late 1990s with the combination of diverse components, which were companies, a local government entity, educational institutions, and human resources. In order to hold ability of standing on its own way in a hard time when the local cultural industries could not had developed by themselves, it urgently required the encouragement policy in the name of industry development. GIMC (Gangwon Information & Multimedia Corporation) was established in this situation, and policy strategies for promoting the cultural cluster was decided on the basis of GIMC's strategies. This article analyzes the evolution process of the local cluster and suggests characteristics of its every stage--initiation, development, and decline--on the basis of cluster competition concept because of the problem to deal with the evolution process of cluster from the existing viewpoint. This article finds out that Chuncheon cluster embarked on cultural cluster strategies without concerning basic elements which had to be prepared from the initial stage. This problem worked as the serious obstacle hampering development of Chunchen cluster. This problem was the matter of policies in providing a direction of industry development as well as leading a local cultural cluster and led to a result of weakening the connection among cluster components. As a result, this article shows that the current status of Chuncheon cultural cluster is being entered the decline stage, and, therefore, suggests that the advanced policy to promote cluster for a next round is urgently needed. Stable closing the first round of cultural cluster policies and thorough preparation for the second round is the only practical solution to minimize side effects of cluster decline. It is the prerequisite to restore trust and, at the same time, reinforce relationship between members who consist of Chuncheon cultural cluster.
