The availability of the thermal energy has been deeply recognized recently to encourage the cascade usage of thermal energy from combustion. Within the frame work, a 1 kW class Stirling engine based cogeneration system has been proposed for a unit of a distributed energy system. The capacity has been designed to be adequate for the domestic usage, which requires high compactness as well as low emission and noised. To develop a highly efficient system with satisfying these requirements, a premixed slot flame burner has been proposed and a series of numerical simulation has been performed to establish a design tool for the combustion chamber. The thermal radiation model has been found to highly affect the computational results and a proper resolution to analyze the heat transfer characteristics of the high temperature heat exchanger. Finally, the combustion characteristics of the premixed flame with the metal fiber type burner has been studied.

Influnced by the official uniform system of China, the colour culture of Korea has changed with time. The ancient colour has included the philo-sophical conception as well as the meaning of thoughts. Forming its tradition, the colour has been accepted in usual life. The philosophy of the Five Element has been developed in the area of Oriental culture and it has influnced to the colour of costume. The five colours(blue, red, yellow, white and black) as the Five Elements colours have disticted the social position. Owing to the fackt, the colour costume has preserved the important meaning. In accordance with the theory of the Five Elements the five colours of costume told its purpose, social position and age. Moreover the relationship among the Five Elements, the direction and the reason have been applied to it with time. Yellow and red have been usually used by kings and high ranking officals, white has been the basic colour for traditional Korean clothes, which hs indicated the integrity symbolizing our race. The Five Elements Colours preserving the theory of Korean the Five Elements have been the conception of Korean traditional colour and they have been developing as the meaning of custom.

As elderly population has been increasing, our society has to be prepared the social system. Especially female elderly increasing means that market will change and business model should also change. Every women want to be beautiful and looks young and as women get aged, women eager to be younger and beautiful more. The purposes of this study were to find out how was represented in cosmetic market ad and how elderly customers has been changed. In developed society, baby boomer has been increased, and their power of purchase also has been increased in cosmetic market. In our society, cosmetic market has been developing as customer's demand and whitening focused cosmetics has been increasing especially. Elderly skin need more moisture focused cosmetics and for developing the elderly cosmetic market in Korea, we need more research about korean elderly women's social psychological character and customer's character.

The symptoms that have same pathologic pattern written in the chapter of Soyangin's general pathology of the book 'Dongyi Soose Bowon' can give us a key to the Dr.Lee Je-Ma's point of view about the constitutional pathophysiology. As the result, Dr. Lee called the person who has yang-hyperactivity/yin-hypoactivity as So-Yang-In. And the Soyangin has two basic pathologic pathway ; excess of Yang-hyperactivity/excess of Yin-hypoactivity. Each pathologic pathway has variatons though, the pathologic pattern results in above two type. Excess Yin-hypoactivity has three variations of pathologic pattern. 1. smaller excess of Yin-hypoactivity with the normal range of Yang-hyperactivity 2. larger excess Yin-hypoactivity with the excitation of Yang-hyperactivity by the extrinsic factor 3. smaller excess Yin-hypoactivity with the loss of Yang-hyperactivity. And excess Yang-hyperactivity also has three variations. In my point of view, CVA, Hematemesis, Vommiting, Abdominal Pain, Gastric Dyscomfort has No.3 type and Asthmatic condition, Dysentery, Edema has No.1 type.

Topology optimization. has been evolved into a very efficient conceptual design tool and has been utilized into design engineering processes in many industrial parts. In recent years, topology optimization has become the focus of structural optimization design and has been researched and widely applied both in academy and industry. Traditional topology optimization has been using homogenization method and optimality criteria method. Homogenization method provides relationship equation between structure which includes many holes and stiffness matrix in FEM. Optimality criteria method is used to update design variables while maintaining that volume fraction is uniform. Traditional topology optimization has advantage of good convergence but has disadvantage of too much convergency time and additive checkerboard prevention algorithm is needed. In one way to solve this problem, element remove method is presented. Then, it is applied to many examples. From the results, it is verified that the time of convergence is very improved and optimal designed results is obtained very similar to the results of traditional topology using 8 nodes per element.

A high precision shear deformable triangular element has been proposed for free vibration analysis of composite trapezoidal plates. The element has twelve nodes at the three sides and four nodes inside the element. Initially the element has fifty-five degrees of freedom, which has been reduced to forty-eight by eliminating the degrees of freedom of the internal nodes through static condensation. Plates having different side ratios (b/a), boundary conditions, thickness ratios (h/a=0.01, 0.1 and 0.2), number of layers and fibre angle orientations have been analyzed by the proposed shear locking free element. Trapezoidal laminate with concentrated mass at the centre has also been analyzed. An efficient mass lumping scheme has been recommended, where the effect of rotary inertia has been included. For validation of the present element and formulation few results of isotropic trapezoidal plate and square composite laminate have been compared with those obtained from open literatures. The numerical results for composite trapezoidal laminate have been given as new results.
