The electronic documents have the documental aspect that can legible by human and the electronic aspect that can be interpreted and processed automatically by machinery. This usability of electronic documents must be the reason that people use them in almost all the business areas rapidly in these days. That is because we have to utilize the characteristics to interchange electronic documents(EDI) effectively and efficiently. The electronic document interchange of Korean government cannot make the best of this benefit due to the traditional way of thinking based on paper document and the viewpoint of individual business, organization. and project. This paper proposed a direction of ED! for Korean government. At first. the concept of electronic docuemnts is defined. The reason and limitations of structuring the documents with XML and the hidden problems of present ED! in Korean public sector are also explained. And the way to preserve information, to design the structure of electronic document. and to maintain relevant standards is proposed.

The Semantic Web has the objective of developing universal media in which machine-processable semantic information can be represented and shared, and it is therefore important to distribute ontologies that represent this kind of semantic information to the Web and make them available to multiple parties. However, the current ontology authoring tools are not operating on the Web, which makes it difficult to distribute ontologies directly to the Web and to create and edit them collaboratively with other people. This paper proposes a framework that facilitates the ontology construction and sharing, realizing easy distribution of ontologies to the Web. Wiki is one of the frameworks for collaborative construction and sharing of knowledge on the Web, and Wiki contents consist of natural language texts and simple markup language for visualization. For better collaboration in creating and sharing ontologies, this paper suggests the Semantic Wiki that embodies the Semantic Web features to the existing Wiki system. The Semantic Wiki framework facilitates the collaboration in ontology co-authoring and sharing for people, and at the same time, makes it possible for the agent software to easily manage the ontology information. Eventually, the Semantic Wiki system accomplishes various tasks including the semantic view, the semantic navigation, and the semantic query.

VoiceXML is new markup language which is designed for web resource navigation via voice based on XML. An application using VoiceXML is classified into mutual-controlled and machine-controlled form dialog structure. Such dialog structures can't construct service which provide free navigation of web resource by user because a scenario is decided by application developer. In this paper, we propose VoiceXML application structure using user-controlled form dialog system which decide service scenario according to user's intention. The proposed application automatically detects recognition candidates from requested information by user, and then system uses recognition candidate as voice-anchor. Also, system connects each voice-anchor with new voice-node. An example of proposed system, we implement news service with IT term dictionary, and we confirm detection and registration of voice-anchor and make an estimate of hit rate about measurement of an successive offer from information according to user's intention and response speed. As the experiment result, we confirmed possibility which is more freely navigation of web resource than existing VoiceXML form dialog systems.

Context-aware systems require sensor data collecting model and context representing model to provide user-demand services. Sensor data collecting model consists of sensor access information, sensor value, and definition of value types. Context representing model involves certain keywords to symbolize environmental information including the field from sensor data collecting model that is described in markup language such as XML. However, duplicated keywords could be assigned to different contextual information by service developers. As a result, the system may cause misunderstanding and misleading wrong situational information from unintended contextual information. In this paper, we propose a context classification model for collecting appropriate access information and defining the specification of context.

기업간 및 기업 대 정부간 문서교환의 요구를 충족시키기 위한 일원으로 기업들은 산업 표준에 따른 전자문서교환(EDI)에 많은 관심과 노력을 기울여왔으며, 국내에서는 한국 EDIFACT위원회를 중심으로 전자문서 표준화가 이루어졌다. 국내 수출업자들이 관세청에 수출신고를 위한 통관 EDI 교환은 주로 부가가치통신망(VAN) 사업자들을 통해 이루어지고 있으나 이러한 EDI 중계 서비스는 특정 VAN사업자들을 통해 EDI서비스가 독점됨에 따라 서비스 이용에 있어 값비싼 전송료 및 통신망 임차비, 잦은 통신 지연, 기업 내부 시스템과의 연계의 어려움 등으로 인하여 많은 문제점을 낳았다. 현재 이러한 전통적 방식의 EDI를 인터넷 기반으로 전환할 때 인터넷의 개방성과 저렴한 사용비용등의 장점으로 인해 비용절감과 사용자 편이성을 크게 증가시킬 것으로 기대된다. 본 연구에서는 인터넷과 웹을 이용하여 통관 EDI 중계 시스템을 개발하였다. 현재 수출을 하고자 하는 주체는 관세청에서 반드시 EDI로 수출에 관한 신고를 하여야 하는바, 본 시스템은 이러한 EDI신고를 인터넷상에서 가능하도록 한 것이다. 본 연구에서는 기존 HTML에서 진일보한 차세대 마크업 언어인 XML을 이용하였다. 본 연구에서 구축한 XML/EDI 통관시스템은 수출신고에 필요한 11개의 전자문서에 대한 XML Schema를 디자인하고, 사용자 관리, SchemaStyleTemplate 관리, XML/EDI 문서관리 XML/EDI변환, EDI 송수신 관리, 인증관리, 로그관리 등의 모듈을 지니고 있으며 개방형 EDI와 인터넷 EDI의 장점을 취합하여 설계되었다. 본 시스템은 기존의 UN/EDIFACT표준을 사용하고 있는 EDI환경과 기존 VAN 방식의 EDI 중계 시스템과 연동되며, 향후 관세청의 XML/EDI 표준 시행을 미리 대비하는 선도연구로서 자리매김이 된다. 본 연구에서는 개발된 XML/EDI 통관시스템은 향후, 서비스의 최대 걸림돌이 되어왔던 값비싼 EDI 사용료의 부담에서 벗어날 수 있게 할 것이며, 저렴한 EDI구축/운영 비용으로 전자문서교환의 활성화와 XML이 인터넷 기반의 문서유통 표준으로 자리매김할 수 있는 중요한 계기가 될 것이다.

The study has planned to analyze the most typical specification validation in Korea and the other countries, which shows the well-formed and schema validation, in purpose to enhance users' conveniences. Also, we suggested the validation system to provide the information compatibility regarding to application programs for non-expert. The featured KML specification supported by the VWorld 3D Desktop and the Google Earth. Based on this above estimation, the system has been designed to inform potential problems and the applicability in 3D Desktop and Google Earth for the user. The KML information passed through the proposed validation is simply expressed on the map, so as instructed the information on the program selection and additional details instruct users as a text file. When not being suitable for the proposed program, another program can be considered, and the problems which may be occurred are also announced to increase the compatibility of KML.

With the wide spread of XML data in various fields, the interest in developing convenient user interfaces for inputting XML data is increasing. Previous works on the automated generation of user interfaces have given insufficient supports for various user environments and inconvenient editing tools for complex documents. In this paper, we presents an approach to generate XForms based user interfaces from XML schemas, for inputting XML data. The proposed method consists of three steps: parsing XML schemas, generating XForms codes, and embedding it into host language documents. Specifically, to generate XFonns codes, the rules for generating XForms codes, which support complex types and map simple types to appropriate input controls, are proposed. Experimental results with various kind of schemas show that the proposed method can generate XForms interfaces successfully.

In this paper, we developed GridGML for efficiently supplying a GML and visualizing the map with partitioning map and caching method to a mobile device. In order to overcome the weighting of a file, which is the biggest weakness of a GML, GridGML extracts only the most necessary parts for the visualization of the map among GML attributes, and makes the file light as a class instance by applying an offset value. GridGML manages a partition based on the visualization area of a mobile device to visualize the map to a mobile device in real time, and transmits the partition area by serializing it for the benefit of transmission. Also, the received partition area is compounded in a mobile device and is visualized by being partitioned again as four visible areas based on the display of a mobile device. Then, the area is managed by applying a caching algorithm in consideration of repetitiveness for a received map for the efficient operation of resources. Also, in order to prevent the delay in transmission time as regards the instance density area of the map, an adaptive map partition mechanism is proposed for maintaining the transmission time uniformly.

This study deals with the relationship between the red tide occurrence and the meteorological and marine factors, the prediction of areas where the red tide is likely to occur based on the information, and the satellite monitoring for the red tide in mid-South Sea of Korea. From 1990 to 2001, the red tide was observed every year and the number of occurrences increased as well. The red tide mostly occurred in July, August, and September. The most important meteorological factor governing the mechanisms of the increase in the number of red tide occurrences is found to be a heavy precipitation. It was found that the favorable marine environmental conditions for the red tide formation are some of marine factors such as the warm water temperature, the low salinity, the high suspended solid, the low phosphorus, and the low nitrogen. The necessary conditions for the red tide occurrence are found to be the heavy precipitation (23.4-54.5 mm) for 2∼4 days, the warm temperature $(24.6∼25.9^{\circ}C)$, proper sunshine (2∼10.3 h), and light winds (2∼4.6 m/s & SW) for the day in red tide occurrence. It was possible to monitor the spatial distributions and concentration of the red tide using the satellite images. It was found that the likely areas for red tide occurrence in August 2000 were Yosu - Dolsan coast, Gamak bay, Namhae coast, Marado coast, Goheung coast, and Deukryang bay.
