We developed a spatial parser generator, SPG, which can automatically create a spatial parser if CMG(Constraint Multiset Grammars) grammars for a visual language are provided by the user with GUI(Graphical User Interface). SPG has the following features. (1) The user uses a visual editor to define the grammars of a virtual language and draw the visual language which should be parsed. (2) The user roughly defines CMG grammars in a visual wan at first. Then the user modifies them and defines final grammars. (3) Because SPG has a constraint solver, it maintains constraints in the parsed virtual language according to the grammars.

Applying Visual Art to pop music performance is gradually increasing. A video editor which simply mixes a number of images was mainly used in the past, but now various computer software make it easy to control visual art by development of computer technology, and it became possible for you to express unique and inimitable idea as well. Compare that a complicated equipment which makes them spend much expense and time was only used in the big size of concert hall in early days, a small and simple one now helps you easily apply your idea to Visual art in Pop music performance even in the small club. The technic of Visual art is being developed gradually especially by using computer The point of this study is how to apply real-time interaction between sound and visual image to interactive media art.

XML은 W3C에서 권고안으로 채택됨으로써, 이를 바탕으로한 CDF, RDF, WIDL, WebBroker 등과 같은 많은 웹 어플리케이션들이 개발되고 있다. XML은 HTML과 같은 단일하고 고정적인 문서 구조에서 벗어나서 자신만의 구조를 가지는 문서를 작성할 수 있도록 해준다. 또한 문서의 내용과 그 내용의 표현이 분리되어 있어, 원 문서의 내용을 변화시키지 않고도 여러 가지 형식으로 표현될 수 있다. 본 논문에서는 이러한 확장된 기능을 가지는 XML 문서를 보다 직관적이고 시각적으로 편집할 수 있는 XML 편집기를 제안한다. 본 시각적 XML을 기반으로 하는 다양한 문서를 편집하는데 범용적으로 사용될 수 있다.

This study aims at developing the high speed/intelligent machining system suing the plug/play method of an open architecture controller. The plug/play technology by the Application Specific Function (ASF), can readily implement the open architecture controller into various machining system or other automatic equipments. For the open architecture controller, this study developed the open HMI, screen editor, ASF, visual builder, and controller OS technology as software components. On the other hand, we developed the I/O module and main board as control hardware system. This study, as an example, presents integration of individual component technologies for the plug/play type open architecture CNC system.

This study has been focused on the development of an open architecture CNC system and integration of core application technology for machine tool such as a remote monitoring/diagnosis system, NURBS interpolation, and cutting process simulation. To do this, we have developed a comprehensive CNC software including the basic HMI, screen editor, ASF, and visual builder. As a control hardware system for machine tool, the universal I/O module and CNC main unit have been developed. Then the remote monitoring/diagnosis system and NURBS interpolation have been implemented in the CNC software. The cutting simulation software will be used for enhancing the productivity of machine tools. Through a simulator and test bed, the whole technology has been verified.

본 논문에서는 메쉬를 편집하는 편집 기술을 위해서 결과 메쉬의 질을 항상시키면서도 다양한 형태로 표현 될 수 있는 편집기를 구현하고 있다. 구현한 편집기에서는 원래 3차원 메쉬가 가지고 있는 모양을 그대로 유지하면서 매핑하기 위해 Floater가 제시한 모양 유지 매개 변수화 방법을 사용한다. 그리고 다단계 B-스플라인 함수를 이용하여 결과 메쉬에 나타날 점들의 새로운 위치를 결정하도록 하며 메쉬의 헝태를 계층적으로 제어하여 다양한 형태를 만들 수 있도록 한다.

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.

To help the blind to find the information easily on World Wide Web, this research has tried to develop the device which enables us to convert HTML for the general into HTML for the blind. This program consists of the items as follows: 1. Web Robot to gather the internet browser and the general HTML. 2. Restoring DB by Parsing process 3. Multimedia editor for the use of web DB to add the literal and acoustic description to the editing function. 4. Convertor which gathers the DB and then changes into HTML for the blind. This project is designed to make it easy for the manager to establish the web site for the blind. We expect that this program will basically help the blind to overcome the inequality in the common information.

Due to the drastic improvement of computer hardware and operating system, it is easy to break through the main defects of limited computer memory and processing time, etc. To keep up with this situation, this paper is focused on developing the preprocessor program with the input method based on vector graphic editor and the preprocessing technique including automatic node generation algorithm for the $\rho$-version finite element program. To develop this preprocessor program, the special data structure and the OOP(Object Oriented Programming) have been used by the Visual Basic 4.0. The Special data structure is proposed to describe the geometric data of node numberings and coordinates suitable for the $\rho$-version finite element program, which are quite different from the comvential h-version finite element program.

XML은 어떠한 정보든지 구조화할 수 있으며, 데이터와 스타일 정보를 철저히 분리함으로써 컴퓨터가 처리할 수 있는 메타데이터를 제공하여 정보검색의 정확성을 높이는 획기적인 계기를 마련하였다. XML 데이터와 스타일의 분리를 위해 XML 기반의 문서를 표현하기 위한 스타일시트인 XSLT가 제안되었지만, 이는 전문적인 지식이 없는 일반인이 사용하기에 매우 어려울 뿐만 아니라, 작성하는데도 많은 시간과 비용이 필요하다. 이에 대한 대안으로 현재 XSLT 문서 편집 시스템이 상용화되어 출시되고 있지만. 사용이 너무 복잡하고 어려워 문서 편집 시스템의 요구조건을 충족하기에는 미흡하다. 이에 본 논문에서는 일반인도 쉽게 XML 기반의 문서 구조와 스타일시트를 생성할 수 있는 시각적 환경 기반의 XMㄴ 기반 문서 편집 시스템을 구현하고, 이를 실제 적용하여 기존 시스템과의 성능 평가를 통해 시스템의 성능을 검증하였다. 또한 문서 구조에 따른 데이터베이스 테이블을 동적으로 생성하여 XML 기반 문서 관리의 효용성을 다각도로 제시하였다.
