The design process of machine tools is regarded as a sequential, discrete, and inefficient works as it requires various kinds of design tools and many working hours. This paper describes an integrated design system embedding a design methodology that can support efficiently and systematically the conceptual structural design of machine tools. The system is a knowledge-based design system and has four machine-tool-specific functional modules including configuration design, configuration analysis, structure design, and structural analysis support module. Through the configuration design and analysis module, a machine configuration appropriate for design requirements is selected, and then the arrangement of ribs fer each structural part is decided in the structure design module. Also, the structural analysis support module is used to evaluate design result by utilizing structural analysis software, ANSYS. The system is applied to design of a tapping machine, and shows that the machine structure can be designed fast and conveniently by processing each design step interactively.

The purpose of the present paper are not to develope machine tools of new concepts and advanced mechanisms but to introduce and apply new methods and concepts in the design procedure by using and changing the previously existing technologies. In this paper 3D modeller was proposed for designing machine tools and the design and the better manufacturability checking than 2D one so that design error was dramatically reduced. As designer may easily understand the real shape of a part and assembly object, it's easy to draw the drawings not only in a conceptual design but also in a detailed design. Also, design automation software enabled designer to consider the real important design parameters by reducing time to spend in estimating and calculating the strength of the model by the computer aided automatic calculation instead of a tedious and complex calculation by manual method and help him to easily make the decision for selecting the stocks and design the structure of part or unit of machine tools.

The appearance of new machine tools with higher flexibility is in need of a basic structure design system for establishing the systematic and rationalized design and manufacturing procedures. In this study. the basic structure design system for machine tools is realized based on the modular construction method. Machine tools are represented as a whole and modular complex with the directed graph, and all possible structural configurations and codes of machine tools for satisfying the machining requirement are derived from the DNA data and connecting patterns of basic structural elements. Especially the structural configurations of machine tools are visualized by the solid modeling techniques and 3-D graphics techniques.

The purpose of this study was to explore how designers use software-based design tools for ideation and collaboration (for two cases: with designers and with developers). We conducted logistic regression analysis and random forest analysis. Software-based design tools are more popular among product designers and affiliated with design organizations with 51 to 100 members. We identify the features that influence designers to use design tools for the ideation and collaboration, and how these usage patterns are interrelated. Interrelated usage pattern is a key consideration for location of the menu and convenience of use. The results imply that reinforcement of the design tool features per designer profile is required and that design management should be consistent with the field of design and the nature of the organization.

디지털 기술의 발전으로 디자인 대상, 대상의 속성, 디자이너의 역할이 변화하고 있다. 본 논문에서는 변화된 디자인 환경의 새로운 디자인 도구로써 프로토타이핑의 역할을 재조명하고 인터랙티브 디지털 제품을 디자인하는 과정에 디자이너들이 적극적으로 활용할 수 있는 다양한 프로토타이핑 도구들을 조사 분석하였다. 관련 분야의 프로토타이핑 방법을 분석하여 프로토타입의 완성도, 디자인 프로세스, 디자인 대상과의 연계성을 중심으로 체계화하였다. 프로토타이핑 도구의 연구들에 대한 분석을 바탕으로 효과적인 프로토타이핑 도구의 활용에 대한 시사점을 도출하였다. 주요 분석 결과로 컨셉 디자인 단계에 중요한 역할을 하는 새로운 프로토타이핑 방법과 도구를 숙지해야 하며, 디자인 대상과 목표에 부합하는 다양한 프로토타이핑 방법들을 활용해야 한다는 점을 파악하였다. 그리고 구현기술에 얽매이지 않고 새로운 컨셉의 탐색에 기여할 수 있는 프로토타이핑 도구에 과한 추가적인 연구가 필요함을 알 수 있었다. 타 분야 전문가들과의 긴밀한 협업으로 프로토타이핑의 효율화를 꾀할 수 있으며 디자이너들이 주로 활용하는 기존 도구를 기반으로 하는 구현 환경을 적절히 활용하는 것이 효과적이다. 조사분석 결과는 디자이너들이 새로운 문제에 직면했을 때 적절한 프로토타이핑 도구를 선택해서 활용학 수 있는 기초로 활용될 수 있다. 또한 디자인 프로세스의 효율성 개선과 교육에 실질적인 기여를 할 수 있을 것으로 기대된다.

개인용 컴퓨터와 인터넷의 발달은 교수자와 학습자, 학습자와 학습자의 관계변화를 야기하였으며 대표적으로 전통적인 학습방법으로서의 일대일, 면대면 수업방식은 디지털 기반의 학습모형으로 변화를 죄하고 있다. 이러한 환경의 변화는 새로운 교육 정보로서의 적절한 디자인 도구와 재료의 등장이 교수와 학습, 모두의 입장에서 필요하게 되었음을 의미한다. 본 연구는 디지털 기술 기반에서의 효과적인 기초디자인 수업을 위하여 새로운 형식의 그래픽 툴(Basic Graphic Tools)을 개발하는 데 있다. 전통적인 학습 환경과의 차이는 최소화하면서 디지털 기술에서 가능한 재료와 도구의 다양성을 최대로 이끌어내는 것이다. Basic Graphic Tools(이하 BGTs)는 학생들의 선수 지식 유무와 학습 기술의 편차, 전통적인 훈련 방식과 첨단의 방식이 공존하는 상황에서 학습자에게는 기초디자인 과정에서 요구되는 디자인 원리를 학습하고 시야를 넓힐 수 있는 디지털 디자인 도구로서, 교수자에게는 효율적이고 생산적인 강의를 위한 새로운 교육 도구로 개발되었다. 기초 디자인 훈련프로그램으로서의 BGTs개발과 실험을 통해 새로운 교육 도구로서의 활용 가능성을 살펴보고 기초디자인 교육과정에서 학습자로 하여금 수월성을 갖게 하는 것이다. 기초디자인 학습 툴로서의 신뢰성 향상을 위해 C 대학에 개설된 e강의실을 통해 디자인 작업 일부가 시행되었다. 이를 근거로 Learning Guide/Performance Test가 이루어졌으며 그 결과 매우 높은 사용 가능성을 확보하였고 동시에 추후 연구과제로서 BGTs를 이용한 기초디자인 프로그램의 개발 가능성을 타진하였다.

This paper presents a design and implementation of CAD(Computer-Aided Design) system with tools and design environments for IC(Intergrated Circuits)design. The CAD system can be easily installed in various sites with limited resources, since most CAD tools and design environments are available in the public-domain and Unix & X Window-based PC-386 and Workstation is used for the hardware platform. In order to improve the flexibility of the CAD system, objects are defined in the context of tools and environments` and object tables are programmed to describe the integration of CAD tools and design environments. During the execution, tool-objects deal with intertool communication and round-robin mechanism to incrementally control the execution of CAD tools. The IC design of LPC(Linear Predictive Coding) Speech Synthesizer is carried out to find out improvements and bugs of the CAD system.

The diversity of students is getting increased in the contemporary classroom. To deal with the diversity, differentiated instruction (DI) should be considered as a way of providing alternative approaches to content, process and product according to the students' readiness, interest, and learning needs. Teachers have problems and difficulties in supporting different student's needs. In fact, teachers need proven tools including framework, guidelines or computing systems to help to practice DI in real context. According to the activity theory, tools influence on how people act and think and even their social practice, playing a crucial role in mediating the activities with people. In DI practice, there are also some studies about physical and abstract tools, but they have been not widely utilized by teachers in real schools. It means that more innovative tool to promote DI might be required. Therefore, to design a better tool to mediate the DI activities with teacher, case studies were conducted. In order to elicit the design implications, two physical and two abstract tools for DI practice were analyzed as case studies. Through the analysis of the case studies, eight design implications better to facilitate DI practice were suggested. This study has implications in suggesting design guidelines for teachers' tools to facilitate their DI practice by analyzing case studies in DI practices for an innovative tool in the educational practice.

The research focused quantitative comparisons of protocols occurring in the architectural massing process using two different tools, three-dimensional(3D) modeler and traditional design tools, to aid architectural massing education. Through the protocol analysis from some experiments, the research identified the following conclusions: 1) Usage of traditional tools produced much higher protocol rate in proposing solution, evaluating proposed solution, explicitness of strategies. This result seemed to be from convenience of traditional tools causing faster visual cognitive cycle. 2) Usage of 3D modeler produced much higher protocol rate concerning attempts of making design vocabulary. The result indicated 3D modeler has relatively effective functions for mass generation and orientation, however it still has some weaknesses on display interface which cause designer's lower idea generations compared to traditional design tools.
