This study is for developing a programming education course to improve pre-service teachers' pedagogical content knowledge(PCK) of programming education. A 40-hour training course was designed with App Inventor, a block-based mobile programming environment, and with problem-based learning method and project-based learning method. After the curriculum was adopted to 12 undergraduate students, the effect of education was tested with a programming PCK questionnaire. As a result, after a 20-hour problem-based learning class, overall score and teaching method score were enhanced significantly. After another 20-hour project-based learning class, content knowledge, teaching method, and curriculum score were improved.

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.

본 연구에서는 지식경영을 실시하기 전에 자사의 현 상태를 진단할 수 있는 조직의 지식경영 준비도 측정 도구를 개발하였다. 조직 내 지식활동을 총체적으로 분석하기 위해 '지식고도화 모형'을 기반으로 해서, 각 영역에 사회적 요인과 기술적 요인으로 구분된 틀을 적용하여 연역하였다. 연역한 결과, 사람, 문화, 제도, 프로세스, 기술의 5차원에서 총 22개의 측정항목이 도출되었고, 도출된 요인의 타당도와 신뢰도 검증을 통해 최종적으로 5차원에서 총 21 개의 측정항목이 도출되었다.(중략)

유비쿼터스 컴퓨팅 환경에서 서비스를 제공함에 있어 지능적인 수행 능력은 사용자의 만족도를 높여주는 핵심 요소이다. 시스템의 지능을 부여하기 위해서는 지식을 관리, 처리, 활용하는 기능이 필요한데, 이들 기능은 그 지식이 어떻게 표현되어 있는지에 큰 영향을 받는다. 일차 술어 논리 기반 지식 표현 방법은 폭넓은 표현 범위와 유연한 지식 정의, 추론 방법으로 선호되고 있지만, 복잡한 계산 비용을 갖고 있기 때문에, 전문적인 지식 처리 시스템이 아닌 경우, 불필요한 계산 비용이 소요된다. Description Logic은 Frame기반 지식 표현 방식으로 일차 술어 논리를 사용하는 것보다 지식을 표현할 수 있는 범위는 제한적이지만, 빠른 추론 결과를 보장해 준다. 유비쿼터스 컴퓨팅 환경에서는 분산된 다양한 오브젝트들이 협력과정을 통해 사용자에게 지능적인 서비스를 제공하게 되고, 이들 개별적인 오브젝트들은 저사양의 계산능력을 갖고 있다고 가정된다. 그러므로, 저사양의 컴퓨팅 오브젝트들을 조합하여 지능적인 서비스를 성공적으로 제공하기 위해서, 각각의 오브젝트들은 제한된 지식을 효과적으로 관리할 수 있는 방법이 필요하다. 이를 위해 본 논문에서는 Frame 기반의 Description Logic을 기반으로 SUNHI의 표현 범위를 가진 인식론적 온톨로지 표현 언어를 제안하고, SUNHI의 표현 범위의 효율성을 증명하고자 한다.

In this study, we propose an ontology based knowledge service system for efficient and sustainable sports events management with information and communication technology. For delivering personalized information and knowledge which relate on sports event operation and management, we analyze the core operations and suggest structure of sport event life-cycle process. Also, we design ontology based knowledge service as proposed in this study to apply on a golf tournament event management system.

This study was conducted to verify the mediating effect of knowledge sharing activity on the effect of trust between consultants on consulting satisfaction during consulting collaboration process. Regression analysis was performed using SPSS 23 based on the survey data. The results showed that trust between consultants had significant effects on knowledge sharing and on consulting satisfaction. Knowledge sharing activities partially mediated the effects of trust between consultants on consulting satisfaction. Further research is required to find out the various factors that are needed to further enhance competence and knowledge sharing for consultants in order to facilitate collaborative work in a rapid change of management environment.

The objective of this study is to design an automatic abstracting system through the analysis of natural language texts. For this purpose a knowledge-based system operating on the basis of domain knowledge was developed. The procedure of generating an abstract consists of three steps: (1) A knowledge-base containing domain knowledge necessary to understand a text is constructed using frame and semantic network structures,and preliminary abstracts are prepared for various cases. (2) Input text is analysed on the basis of domain knowledge in order to extract information filling slots of the abstract with. (3) A Preliminary abstract corresponding to the input text is called and filled with the information, completing the abstract.
