We present a framework of an intelligent design support system for embodiment design of machine tools which can support efficiently and systematically the machine design by utilizing design knowledge such as objects(part), know-how, public, evaluation, and procedures. The design knowledge of machining center has been accumulated through interview with design experts of machine tool companies. The processes of embodiment design of machining center are established. We also introduce a hybrid knowledge representation so that the systm can easily deal with various and complicated design knowledge. The intelligent design system is being developed on the basis of object-oriented programming, and all parts of a design object, machining center, are also classified by the object-oriented modeling. For the demonstration of effectiveness of the suggested system, a structural design system for machine tools is implemented.

Many customers are no longer satisfied with mass-produced goods. They are demanding customization and rapid delivery of innovative products. Many companies are now realizing that the best way to reduce life cycle costs is to evolve a more effective product development paradigm using Internet and web based technologies. Yet there remains a gap between current market demands and product development paradigms. The existing CAD systems require that product developers possess all the design analysis tools in-house making it impractical to employ all the needed and newest tools. Hence, this paper addresses how assembly operation analysis can be embedded transparently and remotely into a service-oriented collaborative assembly design environment. A new assembly operation analysis framework is introduced and a relevant architecture and tools are developed to realize the framework. Instead of the current sequential process for verifying and validating an assembly design, a new Virtual Assembly Analysis (VAA) method is introduced in the paper to predict the various effects of joining during actual collaborative design. As a case study, arc welding and riveting processes are investigated. New service-oriented VAA architecture and its VAA components are proposed and implemented on prototype mechanical assemblies.

최근 코로나로 인해 대면으로 커뮤니케이션하기 어려운 상황이다. 이를 해결하기 위해 다양한 플랫폼 형태의 커뮤니케이션 툴이 개발되고 있다. 본 연구를 위해 20-40대 현업에서 근무하고 있는 직장인 대상으로 프로젝트 시 가장 많이 사용하고 있는 툴은 무엇이며, 협업 중 가장 힘든 문제점은 무엇이었는지를 알기 위해 설문조사를 시행하였다. 분석 결과, 실무자들은 업무를 위해 평소 자주 사용했던 익숙한 툴을 사용하고 있으며, 협업 중 원활하지 않은 커뮤니케이션이 가장 힘들다고 응답하였다. 본 연구에서는 현재 국내 디자이너와 개발자들이 협업에서 사용하고 있는 도구와 용도에 대해 파악하고, 문제점을 해결하기 위한 방향을 제안하고자 한다.

A key factor far realizing the internet-based virtual manufacturing system(VMS) and virtual enter-prise(VE) is how to precisely and effectively represent the machine elements and mechanics. In this paper, we present methods to represent the numerically controlled machine tools in the internet environment. The method is composed of: 1) geometrical modeling of the machine tools, 2) kinematic modeling for the movements of the machine tools, and 3) representing the developed model in the internet infrastructure. Based on the models. a web-based virtual machine tools (WVMT) is developed, and it can be accessed at hrrp://wvmt.postech.ac.kr. The WVMT can be used for various purposes: 1) web-based virtual manufacturing system, 2) web-based CAM system, and 3) CNC educational tools for the vocational school through internet.

본 논문은 그래픽 디자인에서 디자인리서치의 중요성과 사회와 인간과 함께하는 디자인적 방법(Design tools)의 이해 고취가 목표이다. 본 연구는 총 60명을 대상으로 연구를 진행하였으며, 참여자들은 IDEO 툴킷(방법)을 활용하였다. 총 세 개의 설문조사가 이루어졌으면 두 개의 설문지는 동일한 형태로 프로젝트 참여 '사전'과 '사후'에 각각 사용되었다. 마지막은 학생들의 작업을 평가하기 위해 전문가 6인의 조사가 이루어졌다. 예비분석에서는 학생들의 프로젝트 이전의 리서치 경향 인터넷과 문헌자료에 의존도가 매우 높고 체계적인 연구의 형태를 보이지 않았다. 본 분석을 통해서는 리서치에 많은 시간을 할애하고 디자인적 방법을 사용한 그룹의 평가가 긍정적으로 나타났다. 특히, '관찰'기법을 이용한 그룹의 긍정적 평가가 높게 나타났다.

The needs of collaboration among design participants spread in different locations is emphasized in the early design stage in order to not only save time and provide places to meet and talk, but also to save cost for those events as well: This is being realized by the Internet, which helps support a networked, integrated real-time multi-user environment. As the base for collaboration activities moves from physical places to cyberspace, the methods of connecting every participant by means of a computer technology have been desired and considered. This study aims at investigating today's collaboration technology in the architectural design process, especially focused on the early stages, in terms of temporal dimensions. In addition, major concepts for and previous efforts and tools of collaborative design have been examined, and a specific recommendation has been proposed for future development of collaborative architectural design systems: That is distributed collaboration, which is accessible and comprehensible to all the professionals in the building design team, which not only allows the sharing of information but also the sharing of understanding, and which facilitates the development of design tools for different aspects of the envisioned collaborative design environment.

비정형형태 생성을 위한 디지털디자인도구의 활용은 작업자의 능력에 따라 극히 주관적으로 활용되기 때문에, 공통적으로 활용될 수 있는 규칙의 설정을 통해 프로토타입 으로서 비정형 생성방법의 설정을 제시하고, 보다 효과적인 비정형 디자인 형태생성방법을 제시하고자 한다. 본 연구는 비정형 형태의 일반적 이론이 아닌 Concept발의-전개 단계에서 Mass구성 및 표현을 위한 비정형형태생성을 위한 디지털디자인도구의 활용 위주로 진행한다. 현대건축의 비정형적 형태는 디지털디자인도구와 디자인개념의 변화에서 시작된다. 선행연구를 통한 비정형적 작품을 사례를 바탕으로, 이를 분석하여 나타나는 형태적 특성을 디지털디자인도구의 언어를 중심으로 해석하고, 디지털디자인도구의 Geometry 변형을 통해 비정형 형태를 구현하는 기법을 제안하고자 한다.

The computer-based simulation tools are currently used overwhelmingly to simulate the performance of automotive designs. Then, the search for an optimal solution that satisfies a number of performance requirements usually involves numerous iterations among several simulation tools. Therefore, meta-modeling techniques are becoming widely used to build approximations of computationally expensive computer analysis tools. The set-based approach proposed in the first report of a four-part paper has been a test bed for the innovation of vehicle structure design process in the Structural Design and Fabrication Committee of JSAE(Society of Automotive Engineers of Japan). In the second report, the proposed design approach is illustrated with a side-door impact beam design example using meta-modeling techniques.

Three-dimensional integrated circuits (3D ICs), starting with memory cubes, have entered the mainstream recently. The benefits many predicted in the past are indeed delivered, including higher memory bandwidth, smaller form factor, and lower energy. However, 3D ICs have yet to find their deployment in aerospace applications. In this paper we first present key design tools and methodologies for high performance, low power, and reliable 3D ICs that mainly target terrestrial applications. Next, we discuss research needs to extend their capabilities to ensure reliable operations under the harsh space environments. We first present a design methodology that performs fine-grained partitioning of functional modules in 3D ICs for power reduction. Next, we discuss our multi-physics reliability analysis tool that identifies thermal and mechanical reliability trouble spots in the given 3D IC layouts. Our tools will help aerospace electronics designers to improve the reliability of these 3D IC components while not degrading their energy benefits.

Public institutions and owners have been introduced to use Building Information Modeling (BIM) tools. Learning BIM becomes an important factor in design process of undergrad program. The purpose of this study is to demonstrate an integrated architectural engineering design process using BIM tools. BIM education programs are analyzed to compare the level of detail in BIM education. An architectural engineering design class needs to involve BIM to introduce integrated process. An architectural engineering design process needs be based on understanding design, building structure, construction and building services. 3D Modeling helps understanding a building structure and checking environment-friendly element analysis. As a result of this research, new process of design education is proposed under four issues.
