In order to improve the frontal crash performance of an Aluminum Space Frame Vehicle, this presents a systematic optimal design process to maximize the crush energy absorption capacity of side-members while satisfying the maximum displacement constraint. In this study, five design types are studied for selecting a good collapse initiator. Then, for the selected collapse initiator type, 7 design variables are defined to represent cross section shape, thickness and bead interval. The systematic optimization processor, R-INOPL uses DOE, RSM and numerical optimization techniques. R-INOPL uses only 14 analyses to solve the 7 design variable optimization problem the final design can improve 103.9% of the internal energy and reduce 13.9% of the maximum displacement.

This paper proposes the Systematic Design Methodology of the Korean High Speed Train. High Speed Train does not operate in isolation and is a part of a rail system which is influenced through input and output effects from the environment and from the neighbouring system. To fullfil its overall desired function, such input and output relationships between the systems must be considered in the system boundary conditions. Therefore, the overall interrelationship of all these effects has to be carefully considered during the design process. Here proposed methodology may provide a guide line and criteria for the systematic problem solving method of that highly complex High Speed Train System.

This paper introduces a systematic top-down and bottom-up design methodology to assist the designer in the implementation of continuous-time (CT) cascade sigma-delta (${\Sigma}{\Delta}$) modulators. The salient features of this methodology are (a) flexible behavioral modeling for optimum accuracy-efficiency trade-offs at different stages of the top-down synthesis process, (b) direct synthesis in the continuous-time domain for minimum circuit complexity and sensitivity, (c) mixed knowledge-based and optimization-based architectural exploration and specification transmission for enhanced circuit performance, and (d) use of Pareto-optimal fronts of building blocks to reduce re-design iterations. The applicability of this methodology will be illustrated via the design of a 12-bit 20 MHz CT ${\Sigma}{\Delta}$ modulator in a 1.2 V 130 nm CMOS technology.

The purpose of this study was to analyze the characteristics of the pre-design of brownfield's by comparing LDA, EPA, and BRA of UK and USA in terms of establish mainbody, brownfield information, development process, opening development information. Such analysis will generate important implications for the development and renewal of brownfield in Korea by gaining insights into the characteristics of brownfield that reflect systematic and effective management and planning for urban renewal. The findings from this study indicate that: 1. Information on brownfield plays an important role at the development and planning stages that precede architectural design. 2. There is a great need for organizations that are responsible for brownfield renewal, such as LDA of UK, EPA and BRA of USA, in Korea, to make information public and to practice systematic management. 3. Discussion on the pre-design that follows contamination and renewal of brownfield and the developmental strategies that satisfy both the developmental and public profits are warranted.

An efficient multi-objective optimization method is presented making use of neural network and a systematic satisficing trade-off method (STOM), in order to simultaneously improve both maneuverability and durability of tire. Objective functions are defined as follows: the sidewall-carcass tension distribution for the former performance while the belt-edge strain energy density for the latter. A back-propagation neural network model approximates the objective functions to reduce the total CPU time required for the sensitivity analysis using finite difference scheme. The satisficing trade-off process between the objective functions showing the remarkably conflicting trends each other is systematically carried out according to our aspiration-level adjustment procedure. The optimization procedure presented is illustrated through the optimum design simulation of a representative automobile tire. The assessment of its numerical merit as well as the optimization results is also presented.

This paper shows a study on a design method and its process for personalization of the industrial fabricated products, and a unit construction system design as its result. Hence this study is starting at a point, the meaning of the personalization in the industrial society to make dear, the using process to analysis with a systematic approaching method and the system of the using process to define. The system of the using process is related in the functions of the industrial product. Therefore a unit which makes up the system of the using process is defined with the technical system theory of the industrial product, and then a design of the system that is made of that units is clarified as a open system. And the propriety and the boundary of the unit construction system design is cleared up by its practical experiment with the personal computer.

By study the basic elements and the development process of the visual identity design, We have the aims in this study to help the design study groups in the country to develop a VI design system with a high degree of efficiency. We clarified the strategic position which the individual basic elements occupy in the visual communication process, by studying the individual function and the character of the basic elements which construct the keynote of VI design system, and the mutual relations among them. Also, we presented in this study the systematic and resonable approaching means in the design development process for the VI system with a high degree of efficiency.

The characteristic of Web 2.0 is openness, participation, share, cooperation and creation. The purpose of this article was to identify learner based knowledge creation strategy through UCC in Web 2.0, to develop UCC by university students and to make systematic UCC process. This article suggested knowledge creation strategy with UCC learning Community of Practice(CoP). UCC was developed by 25 students who registered e-learning in "P" university and conducted interview with students and experts to analyze the contents which related with research questions. Systematic process for developing educational UCC was consisted of sectors such as idea creation, design, development, implementation and evaluation. Main developing process steps were as follows: making subject$\rightarrow$seeking information$\rightarrow$selecting data$\rightarrow$designing contents$\rightarrow$making story board$\rightarrow$planning of filming$\rightarrow$filming$\rightarrow$digitalizing$\rightarrow$editing$\rightarrow$reviewing final product$\rightarrow$implementing$\rightarrow$evaluating. For learner based knowledge creation through UCC, educational institutions have to provide platform for learners' need, and learners create diverse ideas with UCC CoP. This article suggested knowledge creation strategy with sharing collective intelligence through process of UCC design, development, implement and evaluation.

A systematic investigation for the process design in deep drawing is necessary to improve the quality of drawn cups. This study concentrates mainly on the influence of process design strategy on the product quality. Several types of process design were chosen from initial blank of 100mm in diameter to make final cup of 50mm in diameter. Forming analysis are carried out to find out optimal design in terms of drawing force. We assume that the case which shows minimum drawing force in the subsequent operations is the best case. Through experiments it is found that the case which shows minimum drawing force also results in minimum drawing force and better product quality than other case. Thus, it is shown that this design strategy is very effective in the improvement of quality in drawn cups.
