SGML, defined as the ISO 8879, is a meta-language to define a document type, used as basic format for electronic documents. Since an SGML document is composed of a document type definition and a document instance conforms to the definition, it is necessary for SGML document authoring tools to compose and validate document type and document instance. In present, formal models and procedures for SGML documents are not defined, it's not easy to construct such tools. We propose a model of SGML authoring tool consists of SGML parser, document type definition editor, SGML document editor and style editor. We also introduce and implement formal procedure for each component. For user convenience, we adopted icon based visual programming method, and solved the HANGUL problems. The SGML authoring tool is implemented I Windows NT system using java and C++ programming language.

Confucian ideologies formed a unique spatial order in the spatial composition of seowon architecture. Confucian scholars viewed ancient China as the ideal society, so they tried to apply the "Myochim" theory, the architectural system of the time, to the Joseon society. However, it was not easy to apply ancient architectural ideas in Joseon in the 16th century. Therefore, various opinions were presented by scholars to establish the relationship between Joseon alone. Unlike the Ki-ho school application of this theory, the construction of Seowon was done according to ancient principles from a practical standpoint, there were fewer experiments for actual application in Yeong-nam school. This was a pragmatic attitude that presupposes a clear difference between the ancient Chinese system and the reality of Joseon in the 17th century.

In this paper, we developed digital TV interactive game using mobile device. This enables a TV viewer to participate in the game using mobile devices. Recently, advanced interface is adopted in the mobile devices, especially touchpad type interface is favorable. Such type interface has the advantage of more familiar interface for users, and the user can input various type of action. Using a mobile phone enables many users can participate in the TV game, and provides a private screen. In this paper, we describe contributions of the program in detail, and we present the architecture and a demonstration of the proposed program in a similar broadcasting environment.

This paper discribes the practical application of stability analysis on the revetment structures, and four different sections of revetment structures are considered in this study. As a result of stability analysis, the the section of inclined revetment with T.T.P. block shows the highest safety factor against to the sliding failure of cap concrete block, while the section of inclined revetment with rubble stone shows the highest safety factor against to the straight and circular sliding failure. And the safety factors are increased by increasing of the rigidity of covered materials and by decreasing of the slope angle. For the safety factor of overturnning and bearing capacity, the section of inclined revetment structures shows higher safety factors than the section of vertical structures, and the safety factors are increased by decreasing of the slope angle and by increasing of the bottom width of the structures.

본 논문에서는 자동화 장비들의 제어 및 모니터링 소프트웨어에 대한 쉬운 개발과 유지보수성을 향상시킬 수 있는 프레임워크를 제안한다. 본 논문에서 제안하는 프레임워크는 XML기반의 세 가지 표준 문서 형식(IID, MAP. CMIML), VI Wizard, Generator로 구성된다. VI Wizard는 표준문서형식(IID, MAP, CMIML)을 내장하고. 입력받은 IID와 MAP파일을 이용해서 GUI기반으로 VI(Virtual Instrument)를 구성한다. 새롭게 구성된 VI를 이용하여 장비의 제어정보, 사용자 인터페이스 정보 모니터링 정보, 통신 방법 등에 대한 정보를 기술하는 CMIML을 생성한다. Generator는 VI Wizard에서 생성한 CMIML문서와 실제 장비 드라이버에 대한 API를 입력으로 장비에 대한 제어 및 모니터링 소프트웨어를 자동 생성하게 된다.

Like many types of scientific data, results from simulations of volcanic ash diffusion are of a clustered sparse matrix in the netCDF format. Since these data sets are large in size, they generate high storage and transmission costs. In this paper, we suggest a new method that reduces the size of the data of volcanic ash diffusion simulations by converting the multi-dimensional index to a single dimension and keeping only the starting point and length of the consecutive zeros. This method presents performance that is almost as good as that of ZIP format compression, but does not destroy the netCDF structure. The suggested method is expected to allow for storage space to be efficiently used by reducing both the data size and the network transmission time.

본 논문에서는 일반 데스크탑 PC의 디스플레이 성능에 적합하도록 작성된 유선의 웹 문서를 무선 인터넷 환경의 핸드헬드 계열 소형 단말에서도 효율적으로 표현하기 위한 변환 기법을 제시한다. 이는 기존의 단순한 텍스트 위주의 추출 및 형식의 변환과는 달리, 분석 및 변환을 위한 최소 내용 단위를 설정하고, 이들의 재배치를 통하여 원본 웹 문서의 정보를 보다 정확히 반영한다. 또한 새로운 인덱스 형식으로의 재표현을 통하여 기존의 페이지 조각과 계층적 구조의 인덱스 링크를 이용한 인터페이스보다 편리한 검색 및 페이지 이동을 제공한다. 이 기법은 보다 많은 정보를 복잡한 구조로 표현하는 현재의 웹 문서 특징을 반영하고, 이동 단말들의 고성능화 추세와 함께 화려한 무선 인터넷을 요구하는 사용자들을 고려한 것이다. 전체 변환 과정은 Layout-Forming Tag Analysis Algorithm, Component Grouping Algorithm Component Block Classification Method, Index Generation Method로 구성된다. 변환 시스템의 구성 모듈별 설계와 프로토타입의 구현을 통하여 제안하는 알고리즘 및 변환 방법을 평가하였고, 실제 웹 문서에 대한 실험 결과에서 단말의 소형 화면에 적합하게 변환된 모습을 확인하였다.

When migrate electronic records, the validation of the required metadata in electronic records and verified with the metadata in the document are also important. This paper presents a method and implements a tool to extract data from files in various formats and use them to validate metadata associated with the files in electronic records. Compared to other metadata extraction tools, especially developed in foreign countries, the standard form of documents used in Korean government is taken into account and metadata is extracted from the content of files. The tool compares the extracted data to encapsulated metadata for validation.

In this paper a two-step algorithm is proposed to efficiently generate rebar elements from 3D CAD data in the context of CAD/CAE data transfer. The first step is an algorithm to identify various type rebar objects and their attributes by analyzing 3D CAD data in STEP format, which is one of the international data standards. The second algorithmic step is a procedure to generate one-dimensional rebar elements from the object data made through the first step for finite element analysis or other CAE tasks. Successful rebar element data generation from real 3D CAD data for a reinforced concrete structure shows the efficacy of the proposed algorithm.

Korean cyber universities now provide higher education service to learners but the courses suffer major limitations of low quality and inefficient format of their learning contents. Because of the absence of any standard authoring strategy for learning contents, tutors develop their own courseware with various formats and content structures. In addition, the lack of association between content learners causes them difficulties in finding and reusing related contents. In this paper, we propose an authoring strategy foradvanced learning contents based on SCORM and ontology. Our strategy improvesthe reusability and associativity of learning contents. We demonstrate the effectiveness of our proposed authoring strategy through developing learning contents such as understanding of digital contents.
