  • In the medical field, for the purpose of diagnosis and treatment of diseases, building knowledge base has received a lot of attention. The most important thing to build a knowledge base is representing the knowledge accurately. In this paper we suggest a knowledge representation method using Ontology technique with the datasets obtained from the domestic papers on Alzheimer disease that has received a lot of attention recently in the medical field. The suggested Ontology for Alzheimer disease defines all the possible classes: lexical information from journals such as 'author' and 'publisher' research subjects extracted from 'title', 'abstract', 'keywords', and 'results'. It also included various semantic relationships between classes through the Ontology properties. Inference can be supported since our Ontology adopts hierarchical tree structure for the classes and transitional characteristics of the properties. Therefore, semantic representation based query is allowed as well as simple keyword query, which enables inference based knowledge query using an Ontology query language 'SPARQL'.

  • This study is focusing on the establishment of knowledge management framework of library, supposed that library becomes an integrated knowledge system offering various types of knowledge. Knowledge management of library based on knowledge ecology justifies the logical and physical roles of library, as the sustainer of the knowledge ecosystem in which all the types of social factors consisting of knowledge ecosystem are Interacting to continuously circulate knowledge. The library as the center of knowledge ecosystem should make sure the systemized environment in which knowledge producer is supported to timely distribute knowledge to knowledge consumer through information professional accomplishing the role of knowledge facilitator.

  • Open data has received a lot of attention from around the world. The Korean government is also making efforts to open government data. However, despite the quantitative increase in public data, the lack of data is still pointed out. This paper proposes a method to improve data sharing and utilization by semantically linking public data. First, we propose a knowledge model for expressing administrative districts and their semantic relationships in Korea. An administrative district is an administrative unit that divides the territory of a nation, which is a unit of politics, according to the purpose of the state administration. The knowledge model of the administrative district defines the structure of the administrative district system and the relationship between administrative units based on the Local Autonomy Act. Second, a knowledge graph of the administrative districts is introduced. As a reference information to link public open data at a semantic level, some characteristics of a knowledge graph of administrative districts and methods for linking heterogeneous public open data and improving data quality are addressed. Finally, some use cases are addressed for interlinking between the knowledge graph of the administrative districts and public open data. In particular, national administrative organisations are interlinked with the knowledge graph, and it demonstrates how the knowledge graph can be utilised for improving data identification and data quality.

  • The purpose of this study was to identify the effects of the health leader education on health behavior motivation, perceived health status, knowledge improvement, and life satisfaction among the living in rural area. The subjects consisted of 50 health leaders who participated in the health leader education program. Pre-and post-education tests were collected after education. The data were analyzed using the SPSS 22.0 program with frequency, means, ANOVA, Paired t-test. The data significant changes in motivation, perceived health status, knowledge improvement. The data not significant changes in life satisfaction. Based on this study, a continuous health leader education program through a community health center is needed for rural community people.

  • 진보와 함께 기업들이 지식의 가치를 인식하면서 지식을 창출, 공유 그리고 활용하는 "지식경영"이라는 새로운 패러다임이 다음 세기 초를 주도할 새로운 경영 방식으로 각광받고 있다. 지식경영이란 조직과 그 구성원들 속에 내재해 있는 지식의 가치를 인식하고, 이를 기업 전체 차원의 자산으로 구체화시켜 관리, 공유, 활용하려는 의도에서 비롯된 폭 넓은 의미의 경영 방식이다. 본 고에서는 "지식경영"의 중요성을 인식하고, 선진 기업들이 "지식경영"을 성공적으로 수행하는데 있어 그 요인들은 무엇이며 그 중에서도 "정보관리 전문가"에 대해 논하고자 한다. 그리고 정보 관리자가 정보화, 지식화 라고 하는 시대의 절대적인 흐름에 어떻게 대처해야 하는가를 모색해 보고자 한다.

  • As the role of a library has changed to the integrated management system of knowledge, the library needs new information retrieval tools. The purpose of this study is to propose a method and principle of the Korean-English semantic thesaurus construction for a knowledge management system. The method and principle is as follows; 1) in collecting terminology, I included not only internal documents but external documents on the web as a source for the descriptors extraction. 2) conceptual descriptors are more needed than semantic ones. I also proposed the necessity of the authority files for complement. 3) I proposed the appropriate scale of the descriptors to be 15,000 in a thesaurus. And 4) I proposed a hybrid method that used both a manual and an automatic process in establishing the relationship.

  • 메타인지는 자신의 인지와 학습활동에 대한 지식과 통제활동의 의미로 사용되었으며, 메타인지 지식은 자기 자신의 인지과정에 대하여 스스로 알고 있는 지식을 의미하고, 메타인지적 기능인 자기 조정능력은 학습활동을 스스로 조정하고 통제하면서 학습을 수행하는 능력을 말한다. 학습정보를 제공하는 피드백이 학습자의 학업성취도를 높인다는 연구들은 교수 학습의 과정에서 피드백이 학습효과를 높이고 학업성취도를 증가시키는데 공헌할 수 있다고 밝히고 있다. 이러한 메타인지와 피드백에 관한 선행연구들을 바탕으로 웹을 기반으로 한 프로젝트 학습에서 학습자의 베타인지 수준에 따라 효과적으로 활용할 수 있는 피드백 유형이 필요함을 제안한다.

  • 현재 인류는 지식 기반 사회로 빠르게 발전하고 있으며 지식의 중요도가 상승할수록 지식을 체계적으로 전달하는 교육의 중요성도 상승하고 있다. 이와 더불어 진학 정보들은 폭발적으로 늘어나고 있는 반면 기존의 진학 정보 서비스는 정보의 내용이 극히 단편적이거나 일반적이며 신속한 정보제공이 이루어지지 않는다는 문제점을 안고 잇는 것이 현실이다. 따라서 본 논문에서는 이러한 문제점을 해결하기 위하여 개인의 프로파일을 관리하고, 정보 간의 의미를 파악하여 관련 정보를 쉽게 찾을 수 있도록 시맨틱 웹 기술을 기반으로 의미 기반의 서비스를 제공할 수 있는 맞춤 지학 정보 서비스 시스템을 설계 하고자 한다.

  • A fundamental problem in building an intelligent agent is that an agent does not understand the meaning of its perception or its action. One reason that an agent cannot understand the world is partially caused by a syntactic approach that converts a semantic feature into a simple string. To solve this problem, Cohen introduces a semantic approach that an agent autonomously learns a meaningful representation of physical schemas, on which some advanced conceptual structures are built, from physically interacting with environment using its own sensors and effectors. However, Cohen does not deal with a meta level of conceptual primitive that makes recognizing a schema possible. We propose that negation is a meta schema that enables an agent to recognize a physical schema. We prove some semantic aspects of negation.
