  • This study aims to understand science education conducted in North Korea by analyzing the PCK components shown in two science teacher's guidebooks: (1) Guidebook for 1st grade elementary school and (2) Guidebook for 1st grade middle school. These were published after 2013, when "the first 12-year Universal Compulsory Curriculum" was implemented in North Korea. The analysis shows that both elementary and middle school guidebooks had the highest percentage of content in "Knowledge of Subject Matter", followed by "Knowledge of Instructional Strategies in Science" and "Knowledge of Science Curriculum". On the other hand, "Knowledge of Assessment in Science" and "Knowledge of Students" were significantly low in content. Within the "Knowledge of Subject Matter", both elementary and middle schools had the highest proportion of content in "Concepts and Theories", along with "Experiments and Inquiries" that was also significantly higher than other PCK components. Science teacher's guidebooks in North Korea advocates constructivist teaching style by using "discussions" as the main activity when conveying scientific concepts and theories to students or conducting scientific inquiry classes. Furthermore, "Knowledge of Instructional Strategies in Science" was mainly focused on guiding the "Instruction sequence and method" from the "Topic-specific Strategies", while only a small part of the "Subject-specific Strategies" was being presented. Also, Science teacher's guide books in North Korea included only a few theoretical elements of science education in both the general outline and the particular sections of guidebooks. "Knowledge of Science Curriculum" was mainly composed of "Lesson Objectives" with some inclusion of "Vertical Articulation" and "Horizontal Articulation". "Knowledge of Assessment in Science" and "Knowledge of Students" accounted for a small portion compared to the science teacher's guidebooks in South Korea.

  • The purpose of this study is to investigate the impact of university knowledge capital on the local business activity in the Korean local governments in the year 2015. We found that the increase of the standard deviation of university patent, scientific publications, incumbent firms, and industrial property rights raised the number of new knowledge-intensive firms to 15%, 11%, 54%, and 22%, respectively, in the local economy. In addition, the coefficient which reflects the interaction effects of the knowledge capital between universities and local industries was significant in the given area in the year. On the other hand, in the control variables, the coefficients for the size of local government, population density, and percentage of 20s~40s out of the total population in the local government were significant, showing above 90% level except for the variable of the distance between a local government and Seoul. In particular, when the knowledge capital of the university and industry coexists, the synergistic effect which has influence on the foundation of knowledge-intensive firms was meaningful despite the small scale, and these two types of knowledge capital could be complementary in creating new knowledge-intensive firms in the Korean local economy.

  • 이 연구에서는 통제된 색인어를 이용하여 파악한 지식 구조와 통제되지 않은 키워드를 이용한 지식 구조를 비교하여 두 구조가 어떤 차이점을 보이는지를 살펴보았다. 또한 색인효과가 어떻게 나타나는지, 비통제어를 사용한 경우가 실제적으로 더 상세한 하위 영역을 표현하는지를 확인하고자 하였다. 실험 결과 통제된 색인어인 주제명표목을 사용한 영역지도와 비통제 색인어인 키워드를 사용한 영역지도 둘 다 인공지능 분야의 주요 분야들을 비슷하게 나타냈지만, 주제명표목을 사용한 경우에 색인효과가 일부 나타났다. 그리고 대체적으로 주제명표목에 기반한 영역지도보다는 키워드에 기반한 영역지도가 더 상세하게 나타났다.

  • 비구조 텍스트로부터 지식을 추출하여 온톨로지 기반 지식베이스를 구축하는 연구가 최근 국내외로 다양하게 진행되고 있다. 이러한 목적을 달성하기 위해서는 자연어 텍스트에서 나타난 지식요소들의 다양한 속성들을 표현할 수 있는 온톨로지를 필요로 한다. 디비피디아 역시 위키피디아의 지식들을 표현하기 위하여 디비피디아 온톨로지를 사용한다. 그러나 디비피디아 온톨로지는 위키피디아의 인포박스에 기반한 온톨로지로서, 요약된 정보를 설명하기에는 적합할 수 있으나 자연어 텍스트로 표현된 다양한 지식표현을 충분히 커버하는 것은 보증되지 않는다. 본 논문에서는 자연어 텍스트로 쓰여진 지식을 디비피디아 온톨로지가 충분히 표현할 수 있는지를 검토하고, 또한 그 불완전성을 프레임넷이 어느정도까지 보완할 수 있는지를 살핀다. 이를 통해 한국어 텍스트로부터 지식베이스를 자동구축하는 온톨로지 인스턴스 자동생성 연구의 방향으로서 디비피디아 온톨로지와 프레임넷의 효용성을 전망한다.

  • The Smartphone, one of essential mobile devices widely used recently, can be very effectively applied to capture knowledge on the spot by jointly applying the pervasive functionality of cloud computing. The process of knowledge capturing can be also effectively automated if the topic of knowledge is automatically identified. Therefore, this paper suggests an interdisciplinary approach to automatically acquire knowledge on the spot by combining technologies of text mining-based topic identification and cloud computing-based Smartphone. The Smartphone is used not only as the recorder to record knowledge possessor's dialogue which plays the role of the knowledge source, but also as the sensor to collect knowledge possessor's context data which characterize specific situations surrounding him or her. The support vector machine, one of well-known outperforming text mining algorithms, is applied to extract the topic of knowledge. By relating the topic and context data, a business rule can be formulated, and by aggregating the rule, the topic, context data, and the dictated dialogue, a set of knowledge is automatically acquired.

  • The present study purposed to survey dental hygiene students who will play important roles in guidance and to utilize the data as basic information for setting the direction of dental hygienists' efficient guidance for antismoking and developing antismoking education programs. For this purpose, a survey was conducted with 400 students at the Department of Dental Hygiene in Daejeon, Jollabuk-do and Jollanam-do during the period from May 19 to June 14 in 2008, and drew conclusions as follows: As to correlations among self-efficacy, smoking knowledge, and perception on guidance for antismoking, positive correlation was observed between self-efficacy and smoking knowledge (r=0.102), between self-efficacy and perception on guidance for antismoking (r=0.272), and between smoking knowledge and perception on guidance for antismoking (r=0.352). As to factors affecting perception on guidance for antismoking, the effect was high in order of perception on smoking, smoking knowledge, and self-efficacy. That is, perception on guidance for antismoking was more positive in those who thought that smoking must not be allowed, those with high smoking knowledge, and those with high self-efficacy. For dental hygienists' clinical activities for efficient prevention of smoking and guidance for antismoking, it is necessary to develop curriculums containing various practical contents.

  • 관계추출기의 학습을 위해서는 많은 학습 데이터가 필요한데, 사람이 모으게 되면 많은 비용이 필요하여 원격 지도 학습을 이용한 데이터 수집이 많은 연구에서 사용되고 있다. 원격 지도 학습은 지식베이스를 기반으로 학습 데이터를 자동으로 만들어 내는 방식이기에 비용이 거의 들지 않지만, 지식베이스의 질과 양에 영향을 받는다. 본 연구는 원격 지도 학습을 기본으로 관계추출기의 성능을 향상 시키고, 지식베이스를 확장하는 방안으로 반복학습을 제안한다. 실험을 적은 비용으로 빠르게 진행하기 위해 반복학습을 자동화 하는 시스템을 설계하여 실험을 하였고, 이 시스템으로 관계추출기의 성능이 향상 될 수 있는 가능성을 보였으며, 반복학습을 통한 지식베이스의 확장 방안을 제시한다.

  • Technology commercialization is a reward process for companies' various trials and investment to develop technologies, which can be regarded as a way to figure out company's business performance. To successfully attain companies' purpose via technology commercialization, a variety of knowledge which triggers and completes business activities are needed. This paper suggests a methodology to analyze problems and solutions around the technology commercialization process in terms of knowledge distribution status, especially focused on Korean SMC cases. The knowledge map of this paper is constructed from the knowledge networks and identifies problems and solutions of the target process. A case study for applying proposed concepts to SMC's cases is also performed by checking knowledge distribution status and extracting practical implications. This paper's ideas can be regarded as one of references for SMCs to prepare technology commercialization with guaranteeing facilitated knowledge distribution and utilization.
