현재의 웹 검색은 단순히 키워드매칭만을 통해 필요한 정보들을 검색하기 때문에 그 결과가 사용자가 원하는 정보와는 의미적으로 상이한 결과들을 많이 포함하고 있다. 사용자가 원하는 정보와 의미적으로 정확히 일치하는 정보들을 추출하기 위해서는 웹 자원에 대한 정확한 의미 부여와 웹 자원들 사이의 의미적 연관성을 기술할 수 있는 지식 표현 수단인 온톨로지가 필요하다. 웹 기술표준화 단체인 W3C에서는 이와 같은 웹 자원에 대한 의미 표현 기술로 OWL(Web Ontology Language)이라는 웹 온톨로지 언어를 발표하였으나 아직 이를 효과적으로 저작, 편집할 수 있는 전용 도구의 개발은 아직 미비한 실정이다. 따라서 본 논문은 OWL의 생성 및 편집을 효과적으로 제공할 수 있는 저작 시스템을 설계하고 구현하였다.

The purpose of this study is to explore how pre-service elementary teachers perceive and use smart learning environments. For this purpose, 23 pre-service elementary teachers who took theory and practice in a science education course were asked to develop lesson materials using smart tools and make a self-report questionnaire. These data were categorized in an instructional, exploratory, and interactive approach, depending on how they guided students to access knowledge and information. As a result of the study, pre-service teachers perceived the smart tools as the exploratory and interactive learning tools to be used for students to actively search for and interact with data and knowledge. But in developing lesson materials, they usually used the smart tools for resource sharing and communication in the instructional manner. In conclusion, the gap between their perception of smart tools and lesson materials, and the educational implications will be discussed.

Barriers to health seeking constitute a challenging issue in the treatment of breast cancer. The current meta-synthesis aimed to explore common barriers to health seeking among Malaysian breast cancer patients. From the systematic search, nine studies were found meeting the inclusion criteria. Data extraction revealed that health behavior towards breast cancer among Malaysia women was influenced by knowledge, psychological, sociocultural and medical system factors. In terms of knowledge, most of the Malaysian patients were observed to have cursory information and the reliance on the information provided by media was limiting. Among psychological factors, stress and sense of denial were some of the common factors leading to delay in treatment seeking. Family member's advice, cultural beliefs towards traditional care were some of the common sociocultural factors hindering immediate access to advanced medical diagnosis and care. Lastly, the delay in referral was one of the most common health system-related problems highlighted in most of the studies. In conclusion, there is an immediate need to improve the knowledge and understanding of Malaysian women towards breast cancer. Mass media should liaise with the cancer specialists to disseminate accurate and up-to-date information for the readers and audience, helping in modification of cultural beliefs that hinder timing health seeking. However, such intervention will not improve or rectify the health system related barriers to treatment seeking. Therefore, there is an immediate need for resource adjustment and training programs among health professional to improve their competency and professionalism required to develop an efficient health system.

Selection of appropriate knowledge acquisition and representation techniques is regarded as a major task in the development of expert systems. This depends on the characteristics of problem domains. Expert system builders have often adopted a technique without a formal analysis of application domains. The purpose of this paper is to provide the best knowledge aquisition and representation technique for use in human resource management problem domains. In an attempt to meet this purpose, the conceptual contingency model that suggests the best technique according to managerial decision categories is used as a guidance. In order to determine the priority of managerial decision categories, the Analytic Hierarchy Process and an extended method are proposed.

Shareholders solely depend on annual reports to make investment, credit and other decisions. Investors expect that information should be reliable, relevant, comparable, consistent and thus easy to use for decision making. But whether the importance of annual reports to all shareholders is equally significant is a question of research. Thus, this research study tries to find out the importance of reading annual reports to the investors. A questionnaire survey is conducted on investors considering thirty one general shareholders and six brokers. This research based survey finds that most of the shareholders have no knowledge about accounting or finance and they have little knowledge about capital markets due to lack of training. This study also finds that general shareholders read an annual report at least moderately except value added statement, chairman's review, director's report and rumor. This study recommends human resource should be developed through adequate training, and annual reports should provide transparent and quality information which will ultimately increase the confidence of investors.

Background: The objective of this study is to investigate the needs and importance of basic core competencies required for future society by dental hygienists' viewpoints who are working in the clinical practices and to provide the fundamental data to develop the educational programs based on the competencies in the 21st century so as to enhance their working capability. Methods: A total of 38 questionnaires were used in this study, 3 questionnaires on the general characteristics (age, service years, main job functions) and those in 11 sub-factors of basic core competencies including 4 questionnaires on creativity, 3 on collaboration, 3 on communication, 3 on interpersonal relationship, 3 on problem-solving, 4 on resource control, 4 on self-control and development, 2 on vocational ethics, 3 on knowledge information utilization, 3 on global mind, and 3 on emotional intelligence. Self-reported survey was conducted in the dental hygienists who were working in Seoul and Gyeonggi Province and a total of 195 data were analyzed. Results: Vocational ethics, communication, and collaboration showed the highest on both importance and needs with 4.49 points and 4.34; 4.41 and 4.28; and 4.39 and 4.22, respectively, while global mind showed the lowest with 3.51 and 3.59. Upon Importance-Performance Analysis, 7 items were defined to require maintain the status including vocational ethics, communication, collaboration, interpersonal relationship, self-control, emotional intelligence, and problem-solving while 4 items with lower priority were resource control and development, knowledge information utilization, creativity, and global mind. Conclusion: Based on this study results that suggested the basic core competencies of dental hygienists in alignment with their jobs in the future society, competitive dental hygienists should be developed with the educational programs applied with these competencies.

Author outlines briefly developments of policies relating to telecommunication infrastructure and databases since latter half of 1970′s. There exist three phases. The first phase was from later 1970′s to 1985, which was an initial stage of electronic information service in Japan. In the second phase, 1985～1990, basic policy change made possible the privatization of telecommunication services and proliferation of database products and vendors, The third phase began in early 1990′s with downsizing in computer usage, wide-spreading information networks and rapid dissemination of personal computers. Then author describes offers on policy formation for "novel information infrastructure" and current situation concerning the "Internet" in Japan. Finally, tasks and problems for implementing new generation program for information infrastructure and database usage are pointed out, These are knowledge resource, cost, copyrights and cultural problems including language.

관광산업에서 발생하는 방대한 카드 거래 데이터는 관광객의 소비 행태와 패턴을 암시하는 중요한 자원이 되었다. 거래 데이터에 기반을 둔 스마트 서비스 시스템을 개발하는 것은 관광산업과 지식관리시스템 개발자들의 주요한 목표들 중 하나이다. 그러나 기존 추천 기법의 근간이 되어 온 평점을 활용하기 어렵다는 점은 시스템 설계자들이 학습 과정을 평가하기 어렵게 한다. 또한 시간적, 공간적, 인구통계학적 정보와 같이 추천 성과를 높일 수 있는 보조 요소들을 적절히 활용하는 방법도 어려운 상황이다. 이러한 문제들에 대하여 본 논문은 카드 거래 데이터를 기반으로 관광 서비스를 추천하는 새로운 방식인 CTDDTR을 제안한다. 먼저 Doc2Vec를 이용하여 시간성 선호도를 임베딩하여 관광객 그룹과 서비스 벡터로 데이터를 표현하였다. 다음 단계로 딥러닝 기술 중 하나인 다중 계층 퍼셉트론을 도입하여 얻어진 벡터와 관광 RDF로부터 도출한 보조 요소를 통합하여 심층 추천 모듈을 구성하였다. 추가로, 지식경영 분야의 RFM 분석 기법을 심층 추천 모듈에 도입하여 심층 신경망을 학습하는데 사용되는 평점을 생성함으로써 평점 부재 문제에 대응하였다. 제안한 CTDDTR의 추천 성능을 평가하기 위해 제주도에서 8년 동안 발생한 카드 거래 데이터를 사용하였고, 제안된 방법의 우수한 추천 성능과 보조 요소의 효과를 증명하였다.
