The Korea South-East Power Co., Ltd.(KOSEP) held a design competition for Energy Theme Park at Yeong-Heung power plant in October, 2004. The site is located in 980-1 Oe-ri, Yeong-Heung myun, OngJin gun, Incheon City and has an area of $54,450m^2$. Design objectives of KOSEP were to make environmentally sustainable space, to build a symbolic and gathering place for community members and visitors, to make a tourist spot of Yeong-Heung Island linked with adjacent sight spots in OngJin gun, and to elevate an identity and status of the KOSEP by creating a landscape correspondent to the concept of the building design. The spatial concept of this project was developed by expressing a circular course of energy, named 'energy circle' and accounting for principles of energy generation. By interpreting 'energy circle' and principles of energy generation, and applying it to the site, the design met the various desires of the KOSEP. This design consists of seven theme spaces; the future energy plaza, the wind plaza, the light plaza, the thermal power plaza, a water strider dam, a ecological pond and the stratum plaza. These theme spaces are consecutively placed along the circular path which surrounds the public information building and to represent how power plants generate energy in each space and diverse design techniques and special effects are used.

Kidult trend has continued to influence diverse areas such as fashion, advertisement, interior, cosmetics, and so on in the modern age. As combined word of kid and adult, a Kidult is an adult who participates in youth culture and activities traditionally intended for children. This study intends to check out how the phenomenon of Kidult trend is exhibited in fashion area as well as to develop fashion design for kidult inspired by the images shown in an amusement park. The method of study is two-fold. One is a critical review of previous literature and the other is a development of fashion design based on it. The literature study is referred to books of fashion, books of trend and data collected through internet, and design results are presented using mainly quilting and knitting techniques. The results are as follows. Firstly, a kidult fashion was expressed playful and interesting by the sensibilities of kidults that hope to return to the innocence of childhood reminiscing about the good old days. Secondly, a characteristic of the fashion design for kidults is to display the innovative and diverse design with exaggerated expression and a broad spectrum of colors. One's own unique style can be developed through memories and fantasies from fairy tales in childhood. Thirdly, themes of amusement parks were an appropriate means to show the characteristics of the kidults. A variety of characters and buildings and shapes of the rides in the amusement parks were useful for the design motive targeting for the customers with the kidult characteristics and images of fashion and accessories design. Fourthly, inspired by the amusement parks, the work in this research has presented the new kidult styles designed as various forms combining inner feelings that seek distinctive and unique styles and amusement features.

The construction method using PC(Precast Concrete) has been widely used because the method can shorten the construction period and improve construction quality. In this paper, through the analysis of present design process for PC railway platform, design parameters on the geometry and properties were extracted and 3D information models for PC railway platform were constructed by the parametric modeling technique. Furthermore, the interface module was developed to link 3D models to the structural analysis/design sheet and database program using VBA(Visual Basic Application). This information model could be used in various areas including structural analysis and design, 2D drawing, quantity estimation and 4D simulation including clash detection.

To improve its efficiency, most of the industrial furnace had been used recuperator. However, commonly used metal recuperator is not suitable under condition of temperature higher than $1000^{\circ}C$. The other hand, ceramic recuperator is able to use in high temperature condition. In the present study, the design program based on the basic heat exchanger design theory, and CFD modelling are applied to ceramic recuperator to verify the design results. Using design program to find the optimum design factor on the variation of recuperator condition. The result of this study are as follows : Thinner fin-plate thickness reduces pressure drop and increases heat-transfer rate, However, thin plate or plate with thin thickness(< 5 mm) is difficult to manufacture, due to limited mechanically strength.

In this research, design scheme of fiber Bragg grating(FBG) sensor system for aircraft application is suggested from the results and the know-how from the fon11er researches on structural health monitoring techniques using fiber optic sensors. Design factors to be taken into consideration were derived for both sensor parts including connection and system parts. For the stability of FBG sensor system, design requirements of temperature, vibration, humidity, electromagnetic interference were presented from U. S. military standards. The direction of software programming which increases stability and perfon11ance of the aircraft with the FBG sensor system was also examined.

In this paper, we propose a dynamic model of an escalator which can be used to build a design database. The model permits to estimate the forces applied to the structure by calculating three primary types of forces; the torque required to operate the escalator, the reaction forces at part interconnection points, and contact forces between parts. These forces can then be used to calculate dynamic stresses in the structure which is required to estimate the durability of the structure. Result of the computer model are compared with testing results. This simulation model is used to construct a design database. So when we design a new escalator, this design database can be used to make a new simulation model which makes it possible for us to do a Knowledge-Based-Design.

The safety analysis becomes very essential in the crash environment with the growth of automobile industry. Recently, an airbag system is required to protect the occupant. The effects of an airbag can be evaluated exactly from the barrier or sled test which is quite expensive. The airbag system in a passenger car is analyzed with the occupant analysis program. The modeling of the passenger car including an airbag is established and the results are verified by comparisons with real crash tests. However, the solution of an airbag design can not be obtained easily with the conventional method such as an optimization due to the nonlinearity and complexity of the problem. An iterative design algorithm using the orthogonal array is proposed to overcome the difficulties. The design trend of an airbag is recommended to minimize the injury of an occupant with the proposed design algorithm and the results are discussed.

A topology optimization methodology, named "smooth boundary topology optimization," is proposed to overcome the shortcomings of cell-based methods. Material boundary is represented by B-spline curves and their control points are considered as design variables. The design is improved by either creating a hole or moving control points. To determine which is more beneficial, a selection criterion is defined. Once determined to create a hole, it is represented by a new B-spline and recognized as a new boundary. Because the proposed method deals with the control points of B-spline as design variables, their total number is much smaller than cell-based methods and it ensures smooth boundaries. Differences between our method and level set method are also discussed. It is shown that our method is a natural way of obtaining smooth boundary topology design effectively combining computer graphics technique and design sensitivity analysis.
