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.

Normally, people think the results of engineering design project can be seen and be touched, however, it's not easy to develop such design subjects at IT related program. This matter turns into an initiative of Seoul Accord corresponding to the Washington Accord. In this paper, an engineering design project is developed from the lecture course that can hardly develop a touchable project due to the lack of expanse or the own characteristics of the course in the IT related program that follows the Washington Accord. An open-ended design project with the pre-defined design components and realistic constraints is developed for the Computer Network Design course. Each team consisted of 2 or 3 students performs the project for more than 5 weeks utilizing a software simulator, the Packet Tracer. In order to analyze the effectiveness, we have used various evaluation tools such as final presentation, peer evaluation, survey results, and mid/final exams. We concluded that the hard and soft skills of students have been improved considerably through the project.

This study aimed to develop an engineering design-based science education program for high school students and to investigate its effects on students' science-related attitudes and engineering design abilities. "Creating healthy shoes for maintaining proper posture program" was developed as an activity to come up with creative solutions using the methodology of an engineering design process to solve problems in daily life. The creating healthy shoes for maintaining proper posture program consisted of the following five stages: "defining the problem," "ingathering information related to the problem," "generating the solution," "implementing the best solution," and "evaluating the solution & reflecting." As a result of applying this engineering design-based science education program, it improved the high school students' science-related attitudes and engineering design abilities. Therefore, the program developed in this study has a positive effect on enhancing high school students' science-related attitudes and engineering design abilities. These findings imply that the continuous operation and expansion of activities incorporating an engineering design process in science education are necessary as a teaching and learning strategy for cultivating future science talents.

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.

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.
