This paper proposes a design and realization for the semantic search system. The proposed model includes three Architecture Layers of a Semantic Search System ; (they are conceptually named as) the Knowledge Acquisition, the Knowledge Representation and the Knowledge Utilization. Each of these three Layers are designed to interactively work together, so as to maximize the users' information needs. The Knowledge Acquisition Layer includes index and storage of Semantic Metadata from various source of web contents(eg : text, image, multimedia and so on). The Knowledge Representation Layer includes the ontology schema and instance, through the process of semantic search by ontology based query expansion. Finally, the Knowledge Utilization Layer includes the users to search query intuitively, and get its results without the users'knowledge of semantic web language or ontology. So far as the design and the realization of the semantic search site is concerned, the proposedsemantic search system will offer useful implications to the researchers and practitioners so as to improve the research level to the commercial use.

Three books of home economics were published in Korea 1907 and approved as textbooks for women's education by Korean government from 1908 to 1910 and by the Choseon Government-General from 1912 to 1914. The textbooks contained modern knowledge about housing which was focused on hygine matters and most systematic among the knowledge of that time. The original book of the three was Sinsen Gajunhak(新選家政學) by Shimoda Yutako published in Japan 1990 after her surveying western home economics knowledge. It means the modern housing knowledge educated in Korea around 1910 was affected by Western modern thinking in home economics field that gave the responsibility of housing cleanness for family members' health to housewives. So the knowledge even made the educated women to practice their learning only as wives, which was still traditional.

This study is a descriptive cross-sectional study to identify the perception of post-operative pain management by nursing college students. The study involved 171 nursing college students with clinical practice experience. The data collection was made using structured questionnaires from March to June 2019. The results showed 65.1 percent general knowledge, 58.0 percent knowledge of analgesics and 81.9 percent attitude toward pain management. Pain knowledge and attitude were higher for pain training and men. The general knowledge score for pain showed a positive correlation between knowledge of analgesics, attitudes to pain management. We hope that the results of this study will be used to develop a postoperative pain management program by showing the need for systematic training programs for nursing college students and continuous training for postoperative pain management.

온톨로지는 의미적인 지식을 표현하고, 공유하기 위해서 여러 분야에서 널리 사용되고 있으며, 특히 시멘틱 웹의 상호운용성을 해결할 수 있는 중요한 요소로 자리 잡고 있다. 현재 온톨로지의 구축을 지원하는 다양한 도구들과 방법론들이 제시되고 있지만, 실제 구축되어진 온톨로지가 실용적이고, 도메인의 정보를 정확하게 반영했는지 검증할 수 있는 도구나 방법은 매우 미비하다. 따라서 본 연구에서는 OWL언어로 구축되어진 온톨로지의 소스로부터 온톨로지의 주요 요소들을 추출하여 형식개념분석(Formal Concept Analysis)모델로 변환하고 분석함으로써, 온톨로지에 포함된 구조적인 문제점을 파악할 수 있는 방법과 도구에 대해서 설명한다. 본 연구에서 제시한 온톨로지 분석도구를 사용하면, 구축되어진 온톨로지에 포함된 구조적 오류 및 온톨로지의 구조를 수월하게 파악할 수 있고, 온톨로지 구축작업 및 수정보완에 있어서 더 좋은 개념계층구조를 갖는 온톨로지를 제안할 수 있다.

최근 새로운 데이터마이닝 방법인 지도 군집화가 소개되고 있다. 지도 군집화의 목적은 동일한 클래스가 한 군집에 포함되도록 하는 것이다. 지도 군집화는 데이터에 대한 배경 지식을 획득하거나 분류 방법의 성능을 향상시키기 위한 방법으로 사용된다. 그러나 군집화 방법에서 파생된 지도 군집화 역시 군집화 개수 설정 방법에 따라 효율성이 좌우된다. 따라서 클래스 분포에 따라 최적의 지도 군집화 개수를 찾기 위해 진화알고리즘을 적용할 수 있으나, 진화알고리즘은 대용량 데이터를 처리할 경우 수행 시간이 증가되어 효율성이 감소되는 문제가 있다. 본 논문은 지도 군집화보다 강인한인 지도 퍼지 군집화를 효율적으로 생성하기 위해 진화성이 우수한 휴리스틱 분할 진화알고리즘을 제안한다. 휴리스틱 분할 진화알고리즘은 개체를 생성할 때 문제영역의 지식을 반영한 휴리스틱 연산으로 탐색 시간을 단축시키고, 개체 평가 단계에서 전체 데이터 대신 샘플링된 부분 데이터들을 이용하여 진화하는 분할 진화 방법으로 수행 시간을 단축시킴으로써 진화알고리즘의 효율성을 높인다. 또한 효율적으로 개체를 평가하기 위해 지도 퍼지 군집화 알고리즘인 지도 분할 군집화 알고리즘(SPC: supervised partitional clustering)을 제안한다. 제안한 방법은 이차원 실험 데이터에 대해서 정확성과 효율성을 분석하여 그 타당성을 확인한다.

This paper theoretically derives an algorithm to discover a new type of workflow-based knowledge from workflow models, which is termed workflow-based affiliation network knowledge. In general, workflow intelligence (or business process intelligence) technology consists of four types of techniques that discover, analyze, monitor and control, and predict a series of workflow-based knowledge from workflow models and their execution histories. So, this paper proposes a knowledge discovery algorithm which is able to discover workflow-based affiliation networks that represent the association and participation relationships between activities and performers defined in ICN-based workflow models. In order particularly to prove the correctness and feasibility of the proposed algorithm, this paper tries to apply the algorithm to a specific workflow model and to show that it is able to derive its corresponding workflow-based affiliation network knowledge.

The purpose of this study was to Investigate the preservice elementary teachers' pedagogical content knowledge of addition and subtraction. The subjects for data collection were 29 preservice elementary teachers and data were collected through open ended problems. The findings imply that the preservice elementary teachers show low level of understanding of addition and subtraction such as the word problem posing and the contexts of part-part-whole and compare. The research results indicate that the preservice elementary teachers possess primarily a procedural knowledge of pedagogical content knowledge and don't understand relationship with real-world situation. This study provide the information available on developing program for preservice elementary teachers.

The PCK of teachers about informatics subject, which is viewed as one of required subjects in today's information society, is linked to what and how to teach, and that is very significant in terms of academic education. However, there are currently no efforts to develop items geared toward evaluating the PCK of teachers about informatics subject or to make a factor analysis of those items, though the importance of that subject in information society has been discussed. The purpose of this study was to develop and validate an instrument to size up the PCK of preservice elementary teachers about informatics subject. The finalized instrument consisted of 39 items regarding five factors that involved knowledge of curriculum, knowledge of expression, knowledge of content, knowledge of evaluation and knowledge of teaching methods.

A study of philosophy is a process that archive, reorganize and analyze the earlier works to discover new facts. Philosophy digital resources is necessary to research philosophy because they provide lots of electronic texts, philosophical information, forums, etc. In this paper, we introduce . our result of a research on philosophy digital resources existing in domestic or oversea web sites. We describe the problems which existing resources have and our solution to solve them. Also we provide a guideline to creating philosophy ontology based on topic maps which are data model of ontology. Our philosophy ontology defines hierarchy and associative relationships between philosophical knowledge and support retrieval and exploring of knowledge using semantic information.
