The article presents the method that medium enterprises could manage technical information effectively. There are some merits in using the next generation Web brower, HyperWave as technical information management system. First, it makes anyone else to manage the technical information easily. Second, if he could manages the technical in-formation by using HyperWave, he can input, modify, and delete information effectively. Third, HyperWave system can creat the link to connect the related documents or images. Fourth, it provides various retrieval techniques. Lastly, HyperWave system can organize technical information at a low cost.

최근 네트워크의 발달과 인터넷의 보편화에 따라 지리정보는 않은 분야에서 활용되고 있으며, 그 범위가 해양으로까지 넓혀지고 있다. 하지만 전자해도 등의 해양 지리정보는 선박의 항해와 같은 특수한 목적으로만 사용되어져 왔고 전용의 표시시스템을 사용해야만 하기 때문에 범용적이지 못하다는 단점을 가지고 있다. 또한 기존의 지리정보시스템들은 각각 독자적인 포맷으로 데이터를 표현하고 관리해왔기 때문에 시스템 상호간의 호환성이 떨어지고 데이터의 교환이 용이하지 않았다. 이를 극복하기 위하여 OGC에서는 지리정보를 효과적으로 표현할 수 있는 XML 기반의 GML 표준을 발표하였고, W3C에서는 벡터 그래픽의 표준인 SVG를 제안하였다. 이에 본 논문에서는 선박의 항해에만 제한적으로 사용되던 전자해도를 다양하게 활용하고 비전문가도 이용할 수 있도록 GML과 SVG에 기반한 전자해도 관리시스템을 개발하였다. 즉. GML로 표현된 전자해도를 데이터베이스화하고 사용자의 질의에 부합하는 전자해도를 검색하여 이를 SVG로 변환하여 웹 브라우저를 통하여 서비스를 제공할 수 있는 시스템을 설계하고 구현하였다.

LBS services is a user-centric location based information service, where its importance has been discussed as an essential engine in an Ubiquitous Age. We aimed to develop an ontology reasoning system that enables users to derive recommended results suitable through selection standard reasoning according to various users' preferences. In order to achieve this goal, we designed the Geo-ontology system which enabled the construction of personal characteristics of users, knowledge on personal preference and knowledge on spatial and geographical preference. We also integrated a function of reasoning relevant information through the construction of Cost Value ontology using multi-criteria decision making by giving weight according to users' preference.

Due to the development of the Internet, there are a lot of information around, and the amount of this information is growing exponentially. The information management systems, which are built to manage the numerous amount of information, helps the user retrieve information more accurately and efficiently. However, mobile systems and its built-in file systems, lack in information management and has a limited processing power for real-time data. This paper suggests the middleware system for effective management of large data and enabling real-time data processing. To show the possibility of middleware, the paper implemented a real-time alarm scheduler, which links web database systems and mobile phones.

The purpose of this study is to develop the classification scheme in subject-based directory search engine for educational research information on the web. Five classification systems. Yahoo Korea, Argus Clearinghouse, DDC, ERIC thesaurus and KEDI thesaurus were measured in terms of coverage of subject fields, system logic, accuracy of terminology and efficiency of searching. For the design of Classification Scheme, this study considered the content of subject areas, features of information resources and efficiency based on users. Finally, the Classification Scheme was established in terms of 16 main divisions and 47 sub-divisions in educational research information.

Objectives To grasp the trend of constitution medical industry related to the metabolic disorders by analyzing the web resource.Methods Web search with the search formula ("constitutional" or "spirit") and ("Metabolic" or "diabetes" or "high blood pressure" or "hyperlipidemia" or "obesity") for 20 years (1995.09.10 ~ 2015.09.09.) in the web portal address "Web search with the search formula ("constitutional" or "spirit") and ("Metabolic" or "diabetes" or "high blood pressure" or "hyperlipidemia" or "obesity") for 20 years (1995.09.10 ~ 2015.09.09.) in the web portal address "http://web.search.naver.com".Results In the search area of news, blogs, cafes and knowledge-in, the number of searched pages retrieved by the word "constitution" was about 1.78 million. In the news 9760 cases of "obesity", 4046 cases of "hypertension" and 3253 cases of "diabetes" were searched. In Naver Web search Korean medicine clinics related to "constitution" were 24.3%. If we multiple 25.3% to 1000, the actual number of herbal hospitals, The constitution related to Korean medicine clinics is estimated to be approximately 3160 places. Among metabolic disorders, "Overweight", "Diabetes" and "Hypertension" were most frequently searched.Conclusions Constitutional industry related to metabolic diseases is very actively created on the internet in various areas. Among metabolic diseases, obesity, diabetes, hypertension were found with high frequency.

본 연구는 시맨틱 데이터 정합성 검사와 RDF 트리플 생성 기능을 가진 URI 서버 내 DB 스키마의 자동 생성 방안을 기술한다. URI 서버는 시맨틱 웹 기술 기반 프레임워크 구성에 필요한 핵심 엔진으로서 인스턴스 생성 관리기, 검색 엔진, 추론 엔진 등과의 상호 작용을 통해 시맨틱 데이터를 서비스한다. 도메인이 바뀌거나 서비스가 변경되는 경우 DB 스키마를 전문가에 의해 수작업으로 생성함으로써 서비스 환경 변화에 즉각 대응하지 못하는 문제점을 가진 기존 URI 서버를, 적재되는 온톨로지에 따라 DB 스키마를 동적으로 자동 생성하는 방식으로 변경함으로써 다양한 응용 분야와 도메인에의 높은 이식성(Portability)을 보장할 수 있도록 한다. 기반정보 온톨로지, 응용 온톨로지, 개인화 온톨로지 등 3개 온톨로지 스키마와 11만 건 이상의 Citeseer Open Access Metadata로부터 추출된 인스턴스를 대상으로 한 실험을 통해 URI 서버 내 DB 스키마 자동 생성 가능성을 실증하였다.

온톨로지 구축에서 클래스간 관계 설정은 중요한 부분이다. 본 논문에서는 클래스간 상 하위 관계 외의 관계 설정을 위한 클래스간 관계 자동 정의를 목적으로 의존구문분석의 (주어, 용언) (목적어, 용언) 쌍들을 추출하고, 이렇게 추출된 데이터를 이용하여 용언들을 클러스터링 하는 방법을 제안한다. 도메인 전문 코퍼스 데이터 희귀성 문제를 해결하고자, 웹검색을 결합한 방식을 선택하여 도메인 온톨로지 구축 클래스간 관계 자동 설정에 대한 방법론을 제시한다.

Studies based on food analysis or food databases use the national standard food database. Although Internet information services are increasing gradually, users are only able to get definitive and profitable information using standard food terms. Until now, it has been uncommon to find food retrieval services that include users' regional or historical characteristics. Thus, this study introduces a prototype for Food and Dish Synonym Retrieval (NutriSyn) that includes synonyms and related words. The environments which NutriSyn was implemented were Linux for the server operating system, the Microsoft Windows series for the users' operating system and Apache for a web server. The development languages used are PHP, JavaScript and HTLM with a MySQL database. Users can access NutriSyn using Internet browsers. The main menu items are (1) Food Synonym DB, (2) Dish Synonym DB, (3) Food Information DB, (4) Dish Information DB, and (5) Food and Menu Synonym Retrieval. This system is expected to be a useful tool for food experts and interdisciplinary research.
