Commonly it is perceived that it is difficult to teach engineering design and satisfy accreditation criteria in computer science and engineering related majors. However, since engineering design in these disciplines are a product design, it is more adaptable than other majors which are process design oriented. This paper shows that although there are subtle differences with conventional engineering design, engineering design education in computer science and engineering can be effectively done. This paper concentrates on how engineering design related curriculum can be constructed, what should be considered when designing such curriculum, and how engineering design can be taught in individual design courses(excluding introductory and capstone courses) based on case experience.

The meaning of this research is to make recognition for necessity of ergonomic fashion design research. And the purpose is to provide the guidelines for ergonomic fashion product development. For this, literature research and analysis of empirical illustration of product design indicating ergonomics characteristic are implemented. Among the body-conscious active sportswear, cycle wear, swim suit, and skin scuba wet suit were selected and analyzed. Then they were explained according to the ergonomics characteristics arranged previously. Lastly, the features of ergonomic fashion design were arranged by composition elements of the clothing such as pattern, sewing, material and detail. The characteristics of ergonomic design derived from literature and advanced researches are efficiency, usability, functionality and safety. Through research and analysis, the characteristics of ergonomic fashion design are as followings. In pattern, it is related to the 3D structure division pattern, the reduction pattern design, the closing & opening part design for easy detachment, the receipt and the changeable design. In sewing, it is related to the use of latest sewing techniques and the finish using silicon or rubber band. In material, it is related to the use of high performance fabrics and the proper arrangement of these. In detail, it is related to the convenient detail, the storage detail, the adjustable detail, and the body protection detail.

Objective: This paper discusses how service design is related to two well-known disciplines, interaction design and cognitive systems engineering, which are applied to the design of software, websites and mobile phones, and the design of control room of nuclear power plants and cockpit control, respectively. Background: Service design has been spotlighted recently due to its promisingness to service industry. Successful cases of service design are widely shared among designers. Service design, however, is treated as practice rather than a discipline. Method: It was discussed that it is important to consider the interaction between customers and services as in interaction design, and some domains are complex enough and have functional limitation as in cognitive systems engineering. Results: Models and design tools of the disciplines are introduced and applied to service design practices. Conclusion: It was concluded that service design has the characteristics of both interaction design and cognitive systems engineering.

The design technique of turbo pumps has been developed due to an increasing demand from related industrial fields. But infant stage of turbomachinery in the domestic industry needs more fundamental design method. Among various types of pumps, centrifugal pump was chosen because of its wide industrial application. It is difficult to decide the correct specification of centrifugal impeller, because of its complex flow analysis at the inlet, passage and outlet. This study is limited on the impeller blade design and its related performance analysis.

It is well blown that the product development time in manufacturing industry is critical. A new methodology for a product design knowledge management is required to reduce design errors and to optimize a design process. In this paper, Process-Related design knowledge management and Document Template are introduced to provide a design process to prevent previous design errors and a solution for the desist errors. Also the Document Template is more convenient interface in integrating the design knowledge into a system.

This paper overviews clock design problems related to the circuit reliability in deep submicron design technology. The topics include the clock polarity assignment problem for reducing peak power/ground noise, clock mesh network design problem for tolerating clock delay variation, electromagnetic interference aware clock optimization problem, adjustable delay buffer allocation and assignment problem to support multiple voltage mode designs, and the state encoding problem for reducing peak current in sequential elements. The last topic belongs to finite state machine (FSM) design and is not directly related to the clock design, but it can be viewed that reducing noise at the sequential elements driven by clock signal is contained in the spectrum of reliable circuit design from the clock source down to sequential elements.

In this study, the effect of presence and distribution of masonry infill walls on the mid-rise steel frame structures having soft ground storey was evaluated by implementing finite element (FE) methods. Masonry infill walls were distributed randomly in the upper storey keeping the ground storey open without any infill walls, thus generating the worst case scenario for seismic events. It was observed from the analysis that there was an increase in the seismic design forces, moments and base shear in presence of randomly distributed masonry infill walls which underlines that these design values need to be amplified when designing a mid-rise soft ground storey steel frame with randomly distributed masonry infill. In addition, it was found that the overstrength related force modification factor increased and the ductility related force modification factor decreased with the increase in the amount of masonry infilled bays and panels. These must be accounted for in the design of mid-rise steel frames. Based on the FE analysis results on two mid-rise steel frames, design equations were proposed for determining the over strength and the ductility related force modification factors. However, it was recommended that these equations to be generalized for other steel frame structure systems based on an extensive analysis.

With the rapid development of nowadays technologies, the environment of product development is experiencing structural changes than ever. Manufacturers are put under never-experienced pressures to launch their products in the market both faster and less expensively than their competitors while continuously improving product quality These pressures have given birth to so-called, Concurrent Engineering which is a systematic approach to the integrated, concurrent design of products and their related processes, including manufacture and support. Most manufactiring companies now recognize the importance of concurrent engineering and put heavy emphasis on the research and impementation of concurrent engineering. However, with this fundamental change in the process of product development, designers rarely pay attention to this newly demanding process. Designers still stay in the middle of process, satisfying their roles in dealing with aesthetic points of product. Designers badly need to incorporate the concept of concurrent engineering to design to design process and to adapt to this new environment. With these backgrounds, the study sets the objective to understand the nature of concurrent engineering and explore the possibility of it's application to industrial design. Particularly this study focuses on how the concept of concurrent engineering can be applied from the stage of form development to prototyping. At first, background, objectives, and scope of the study are discussed as an introductory part. It is followed by reviewing theories of concurrent engineering such as definition, history, technologies, examples, state of art and so on. Subsequently industrial design is viewed in terms of concurrent engineering and problems in industrial design are identified. Base on the findinss of precedent part of study, new process of industrial design incorporating concurrent engineering is developed. For the demonstration of new process, a case study of design of palm-top printer is introduced. Case study shows how the sketch, and forms can be transformed into prototyping with the simultaneous cooperation with engineering and other related specialists. Finally the study in summarized and future studies are prospected.
