For the most part of machine design, assembly drawing isaffected byits inserted parts. When a part is inserted in assembly, alreadyd stablished parting line is modified for reasonable representation. for example, break or trim fuction between the lines gives more recognizable drqwing. Most of parts is composed of such that point, line, arc, circle and block. If the part is composed of block, it is very difficult to operate because its attribution is unknown before exploding, but, It is very easy to operate except block. In this paper, it is required that basic feature recognition rules are caused by knowledge-based. This system which shows a good modify tool using AutoCAD system and ADS (Autocad Development System).

W3C has developed the RDF standard for utilizing ontology in Web applications. This paper presents extracting, storing, and applying ontology on product data. The design and tooling information included in STEP-NC files is focused as an example. By analyzing the relationship among the product data, the RDF schema is designed first. Based on the schema ontology if extracted and stored in XML files. As an application of the stored ontology, we can reconfigure the sitemap of product data repositories. In this example, the users can select the view that he or she is interested in (e.g. product, tool, person). With such various views of an product data repository, the users can access the specific data more effectively.

We have developed a real-time software tool to extract a speech feature vector whose time sequences consist of three groups of vector components; the phonetic/acoustic features such as formant frequencies, the phonemic features as outputs on neural networks, and some distances of Japanese phonemes. In those features, since the phoneme distances for Japanese five vowels are applicable to express vowel articulation, we have designed a switch, a volume control and a color representation which are operated by pronouncing vowel sounds. As examples of those vowel interface, we have developed some speech training tools to display a image character or a rolling color ball and to control a cursor's movement for aurally- or vocally-handicapped children. In this paper, we introduce the functions and the principle of those systems.

이 연구는 오디오, 비디오, 이미지, 텍스트 등의 다양한 멀티미디어 객체들을 동기적으로 통합하여 표현하기 위한 SMIL(Synchronized Multimedia Integration Language) 표준을 지원하는 GUI 기반 저작도구의 구현에 대한 것이다. 현재까지 멀티미디어 저작을 위한 다양한 인터페이스가 개발되어 왔다. 본 논문에서는 멀티미디어의 논리적인 프리젠테이션 과정을 직관적으로 표현하기 위한 그래픽 사용자 인터페이스를 제안한다. 본 논문에서 제안하는 사용자 인터페이스는 일반적인 미디어객체들 간의 시간관계를 직관적으로 표현하고 편집할 수 있는 아이콘 기반의 인터페이스와, 미디어간의 세부적인 편집을 지원하는 시간기반의 인터페이스, 미디어 객체들의 공간적 재생 위치를 지정하는 배치(layout) 인터페이스 등이다. 이와 같은 다양한 인터페이스를 통합하여 위지위그(WYSIWYG) 방식으로 SMIL파일을 생성할 수 있다.

A methodology is proposed to share the design information of a gear drive using XML (eXtensible Markup Language). XML is the standard language of the next generation and can be used as a neutral and unique format shared by various Web applications. Since XML is a platform-independent meta-markup language, it is possible to reduce the additional programming efforts for Web applications by using the standardization of technical terminologies. In this study, the structure of design information about gears, shafts, keys and bearings in a gear drive has been made and the terminologies used in the gear drive design process have been authored. The XML DTD(Data Type Definition) for the gear drive design has been declared and the usage of the XML application has been shown.

In this paper a free-form hull design program and performance prediction program for planing boat is introduced. This program enables the designer to do complex geometric hull shape design on a personal computer and accurately to predict power requirements for a given loading and velocity. For a free form design, Bezier curve model is adopted as a basic representation tool of curves and surfaces, and this program has versatile functions to do fairing jobs with a convenient graphical user interface. After creating a hull form the geometric data is provided in a manner compatible with a variety of analysis tools including 'Motion Analysis(by Zarnick)' for prediction of motion characteristics in regular waves, 'Running Attitude (by Savitsky)' for prediction of the running attitude and required power.

This paper describes implementation of a robot programming system for automation of manufacturing products, which is embedded in the C programming language. World representation and motion primitives necessary to describe a manipulator task are provided by a set of procedure calls and user defined data structures. Off-line programming is implemented with graphic simulation as a debugging tool. PUMA 560 manipulators are used as a model for one task which inserts a nonstandard power IC Iota PCB. Communication facilities are provided for collision avoidance or two manipulators.

Representation of product data for exchanging and sharing a plant information was established the International Standard by ISO 10303 (STEP) and ISO 15926, but is not used widely in industrial circles by massiveness of standard and complexity of plant itself Specially, they are embodied to STEP data file(ISO 10303 Parts 21), but STEP file is uncomfortable that a person recognizes, and needs specification creation tool. In this paper, we made the integration schema for control valve through related standards, Also, we suggest the practical use framework for electronic commerce to utilize the XML schema that can represents integrate schema of control valve to use XML that is becoming the latest issue.

The purpose of this paper is to develop the metadata on the information of research result in Science and technology and to design the domain knowledge structure using semantic web technology for further implementation. In this paper, we first analyze the existing theories and techniques related to the metadata in such fields as R&D research result, international standard, and semantic web. Then, we extract and group the relevant factors from Dublin Core, CERIF, and the research results for building the integrated metadata framework. Based on our proposed metadata, we design a domain knowledge structure which employs RDF/RDFS as knowledge representation tool. Therefore, we can implement the ontology which produce the 'intelligent' information service and improve the interoperability between the research institutions. Also, the metadata can be used as the basis for developing National R&D Performance Information, and in terms of research institutions, can be used as tools for managing the their own research results information systematically and consistently.

An efficient synthesis method of cellular architecture FPgA is proposed in this paper. To generate a logical representation called complex term which is to be directly mapped onto the cellular architecture FPGA, and SO or ESOP minimization tool was used in previous methods. Instead, we use a logic function transformed into BDD (binary decision diagram) in the actual generation of the complex temrs. In this process it estimates the cost(i.e. the number of complex terms) for three branches, 0-branch and 1-branches. This process is continued over the whole BDD to do such computation, and we observed that the number of complex terms has been reduced compared to the previous results.
