Design for Six Sigma (DFSS) has been implemented in many companies to enhance their business performance and customer satisfaction. However, DFSS has not been widely applied to the aircraft industry which operates large, complex development programs. In this paper, the characteristics of an aeronautical product development program are analyzed to figure out the limitations of current DFSS methodology and the prerequisite to deployment of DFSS at the program level is suggested.

There have been diverse discourses arguing that new design has been emerging in the 21 st century. However, there have been very few trials to identify systematically the characteristics_of new design paradigm and to develop new design educational program based on them. Thus, this paper aims at development of strategy of new design educational program according to the characteristics of new design paradigm. At first, design is viewed as part of 'culture'and the structure of culture is identified: 'Artifact', 'Value', and 'Basic Assumptions'. Similarly, design is found to comprise of three fundamental attributes: 'Function', 'Aesthetics','Symbolic'. These levels are shown to be in the relation of mutually recycling influences. These structural framework is used to understand the design methods and qualification of designers over the development of design paradigms: vernacular design, machine age, and information-knowledge age. The result leads the list of requirements of new educational design program: 'Human-Centered','Situation-Based','User-Participatory', and 'Intangible'. The model of strategy of new educational design program is developed and proposed.

Recently, because of the global recession of the offshore plant industry and low-cost orders, there has been increasing interest in strengthening the competitiveness of domestic companies for the design and production technologies of offshore plants. However, in the offshore plant design field, the Plant Design Management System (PDMS), which is a 3D CAD program for plant layout developed by AVEVA Marine, is already commonly used as offshore plant design software and widely used in large domestic shipyards and cooperative design companies. Under this background, we have been thinking about ways to design better with the existing software. In this study, we developed a parametric design program to maximize the efficiency and reduce the working time for offshore plant electrical outfit production design based on the Programmable Macro Language (PML) of PDMS. We also examined its performance. By applying the developed program to the offshore plant module selected as an application example, it was confirmed that a 50% improvement in the work efficiency of cable tray design could be obtained compared with the existing method, with work efficiency improvements of 80% or more in other field design work.

The aim of this study was to develop and implement a program based on Cognitive Behavior Therapy (CBT) for female college students experiencing body dissatisfaction. To systematize the program development process, we adopted the service design method. First, we conducted In-Depth Interviews (IDIs) to identify the difficulties faced by six female college students who experience body dissatisfaction, and to determine what kind of help they needed. Second, content analysis of the findings revealed that female college students were experiencing emotional-behavior problems which derived from the discrepancy between their ideal body image and the reality. Third, a prototype of a cognitive reconstruction program was developed to help transform their perceived 'body distortion' to a rational cognitive concept and thus reduce maladaptive consequences of 'body dissatisfaction'. The overall program consisted of three therapeutic components and seven steps. Fourth, to assess the effectiveness of the program, survey and IDIs were conducted. The results revealed that it is appropriate to use a cognitive model to solve problems caused by body dissatisfaction, and that understanding and reconstructing one's own cognitive processes can be effective in reducing body dissatisfaction. However, based on feedback from participants, a number of revisions were proposed, such as including sufficient induction regarding the behavioral change.

Springs for vehicle suspension control the vibration of a car and influence on the ridability, safety, and life of a car. In the paper, the computer aided design program has been developed, which design the leaf spring shape from the given specifications using basic theory and the expert's knowledge, and the design results are checked by the analysis theory in order to increase the accuracy, and feed back to the design input. For the purpose of easy use, this program consists of pull-down menu and interactive input mode. To prove the effectiveness of this program. two springs, of which one is symmetric, other asymmetric, are designed and analyzed, and the outputs are compared to the experiments. Considering the tolerance of the given specifications, the results are good.

This paper introduces the design method of the centrifugal turbo fan and the process of developing the design program of it. The developed design program confirmed the applicability by experimental performance data. Here, we proposed new velocity coefficients and considered various losses such as impeller inlet loss, vane passage flow loss, casing pressure loss, recirculation loss power, and disk friction loss power. Especially, the inlet and outlet widths of the impeller were newly determined by reflecting the experimental results. As a result, this fan design program shows a good performance result regardless of the types of impeller and is expected to be a very useful design tool.

The automated die design program is developed for cold forging of axisymmetric parts which are mainly produced by forward extrusion, backward extrusion, composite extrusion and upsetting. For this study, firstly classification of forged parts and investigation of die construction type usually employed in forging industry are carried out and the most proper type from several kinds of die construction is proposed as a standardized one. Based on the die design rules summarized in the references such as handbooks, technical papers, monthly journals, etc. the automated die design program was made using AutoLISP language available in AutoCAD software of personal computer. This program interactively runs for only input data, for example, forging process, shape of forged parts, type of punch, split of die insert and design of shrinkage rings and then displays details of drawings necessary to make a forging die. When a variety of forging processes and forged parts are tested to examine the validity of this program, it was confirmed to give good results applicable to the forging die design in press shop.

A bellows diaphragm design program for mechanical seal was developed in this study. This program was written in AutoLISP on the AutoCAD system with a personal computer. Basic design concept used in this program is composition of a convolution that is tangent to two lines and five circles from given design parameters(initial radius, inner and outer diameter, thickness, pitch, etc.). The effects of altering some design parameters on stress distribution of bellows were estimated using commercial FEM code, NISAII. As a result, the bellows diaphragm for mechanical seal was successfully designed by the program. The FEM result shows that stress is dependent on straight line length and bellows diameter with same span.

When an escalator is developed or modified to improve its performance, estimation of dynamic characteristics of the escalator is required. But modeling of the escalator for a design purpose is very difficult and time consuming. Especially, it is very difficult for a designer to use the simulation model during design process because preparing a proper model takes time and also the designer needs to know how to use the simulation program. In order to solver these problems, a graphic user interface program that can predict dynamic characteristics of an escalator is developed for the designer. Since this program makes the necessary escalator model for simulation for itself, the designer does not need to know how to use the simulation program while design is in progress. In this paper, a designer oriented interface program is developed and an example is presented to show the effectiveness of the developed program.
