As the population of the aged and the disabled increases, the needs for universal design is also growing. Universal design is to design for diverse users including all ages from children to the elderly, the disabled and non-disabled, the pregnant, the tourist, and etc. This study is intended to develop the design evaluation tool and guidelines of universal design for applying to space design. In order to achieve this, four basic spaces in human living such as residential space, educational space, working space, and cultural space were selected. Then, the elements of universal design were chosen for each space. The numbers of areas in each space were 12 for residential spae, 5 for educational space, 6 for working space, and 6 for cultural space. Also, 60 elements of universal design for residential space, 53 for educational space, 36 for working space, and 46 for cultural space were selected. The field observation with photos and user evaluation survey were carried out for each space by using these elements. Finally, the elements and guidelines of universal design applied for spatial design were suggested. This consisted of 8 areas and 67 elements. This would be useful for designing space for all people.

오늘날 제품개발 환경에서 디자이너는 고유의 디자인 업무뿐 아니라 여러 기능부서의 의견을 수렴하고 통합, 조정하는 교량 또는 촉매로서의 역할을 요구받고 있다. 이러한 변화에 따라 디자이너는 제품기획에서 생산, 판매에 이르는 제품개발의 전 단계에 적극적으로 그 역할을 하지 않을 수 없게 되었다. (중략)

In this study, a tool was developed for analyzing production lead time in turning operations. It is expected to help to reduce machining time and to identify, for example, tool change intervals. The tool was developed using Visual Basic.Net and features a user-friendly graphical user interface (GUI) that allows users to easily input cutting conditions and calculate the usage time and feeding distance for each cutting tool based on a G-code program. Object-oriented programming techniques were also used to encapsulate and classify complex logic, thereby efficiently organizing and managing the functions and data structures of this analysis tool. The analysis tool provides various outputs. It calculates the use time of each detailed process of the turning operation, the use time of each tool, the use time of each type of feeding, and also generates the data needed for cutting time analysis, which can be visualized in charts. The analysis tool developed in this study is expected to significantly contribute to improving the efficiency of manufacturing processes and increasing productivity, particularly, in the manufacturing of components requiring massive material removal, such as aircraft parts.

In the work of contemporary spatialization, the meaning of program is being an important conceptual element beyond simple functional dimension. The design of this diagram allows to balance among changing programs, and it comes into the spotlight as a medium, which links the virtual to the reality as embodying the virtual, which is not embodied realistically, realistically through the design process. In other words, this method is attracting the public attention as a design tool which can concentrate on design process rather than a fixed tool. This study focuses on the role of balancing among mixed programs and the diagram as a design tool. Therefore, the purpose of this study is to analyze and research the work of spatialization, which apply to diagrams of contemporary designers, is to identify operating mechanism and then is to examine the characteristics and importance of them.

An intelligent software system which can support efficiently and systematically machine tool design by utilizing deign knowledge is described in this paper. The process of embodiment design of a machining center was modelled represented by IDEF0 and embedded in the system. A hybrid type inference engine has been introduced so that the system can effec-tively deal with knowledge represented in diversified forms The design system was developed on the basis of object-ori-ented programming and has been coded into one software system which can be ported on Windows NT.

Process design is carried out for a press forming of a CTBA in the rear suspension assembly based on the result of the finite element analysis. The analysis simulates the two-stage stamping process with the initial design and it fully reveals the unfavorable mechanism which develops inferiorities during forming. In this paper, a new design guideline is proposed to modify the process and tool shapes for a single-stage forming process. With the improved tool design, prototypes are fabricated after several try-out processes. Results of the durability tests show that the design requirement of the part is satisfied and the effective weight reduction is achieved.

This paper describes some research works of computer-aided design of blanking and piercing progressive die for stator and rotor parts. An approach to the system is based on knowledge based rules. The deveolped system is composed of six modules such as main program, input and shape treatment, production feasibility check, strip layout, die layout and drawing edit module. Using this system, design parameters ( geometric shapes, die and punch dimensions and dimensions of tool elements) are determined and output is gen- erated in graphic from. Knowledges for tool design are extracted from the plasticity theories, handbooks, relevant references and empirical know-hows of experts in blkanking companies. The developed system provides powerful capabilities for process planning and die design of stator and rotor parts.

Some Developments in computer aided procedures for cold forging process and tool design of rotationally symmetric cup shape parts are described. The developed system enables appropriate forging sequence to be determined automatically, together with details of corresponding preform, die and punch design. The computer program developed is interactive and written in BASIC. This system not only assist the heavy work of designers but greatly shorten the time of design.
