In this study, it was attempted to obtain the fundamental data for the formation and oxidation of soot from a diesel engine. Combustion of spray injected into a cylinder is complex phenomenon having physical and chemical processes, and these processes affect each other. There are many factors in the mechanism of the formation and oxidization of soot and it is necessary to observe spray combustion microscopically. In order to observe with that view, free fuel droplet array was used as an experimental object and the droplet array was injected into an atmospheric combustion chamber with high temperature. Ambient temperature of the combustion chamber, interdroplet spacing, and droplet diameter were selected as parameters, which affect the formation and oxidation of soot. In this study, it was found that the parameters also affect ignition delay of droplet. The ambient temperature especially affected the ignition delay of droplet as well as the flame temperature after self-ignition. As the interdroplet spacing that means the local equivalence ratio in a combustion chamber was narrow, formation of soot was increased. As diameter of droplet was large, surface area of the droplet was also broad, and hence evaporation of the droplet was more active than that of a droplet with relative small diameter.

This study researched TV makeup types with a focus on Korean aesthetics. First, natural beauty is expressed with a random form that excluded artificial techniques or decorations often shown in the form of incompletion and space through TV entertainment programs. Incompletion is what excludes artificial technique and denies the whole completion in expressing a face, it shows the intentional incompletion that leaves it as a bare face that has no type, no color, and no decoration. A pursuit for purity, as nature leads to realizing the internal world of concentrating on the essence of object. Space is what makes it empty without filling, it offers a mental space in the inner side so that diverse images can be imagined beyond external form. This trend is indicated similarly to the tendency that the recent global interest in naturalism yearns for purity in nature and wellbeing. The presentation of skin (preferably healthy looking skin) is given attention; consequently, the similarity was being shown between the TV makeup that focuses on expressing skin and recent trends.

Maximizing profit is the most significant object of commercial places. Especially for some places where its atmosphere is main concern of customers like $Caf{\acute{e}}s$, interior design is crucial. Thus it needs to evaluate human emotion and preference. Human Sensibility Ergonomics which is recently signified in various fields is an attempt to quantitatively analyze factors of human sensibility and apply it to design operation. This study attempted to infuse human sensibility ergonomics into $Caf{\acute{e}}$ interior design and analyzed preferable $Caf{\acute{e}}$ interior design factors. Because most $Caf{\acute{e}}s$ have their own target customers, so we assumed four different target customer groups divided by their age and gender groups in each age group. As a result, the difference of each group could be examined. Middle-aged group and males have main interest in the intensity of luminance, i.e. the brightness, whereas youths and females attach importance to both quality of light and color. In addition, there is a tendency for middle-aged group and males to see $Caf{\acute{e}}$ as a public place while young people and females recognize $Caf{\acute{e}}$ as a place for entertainment. Taking the result of this study into consideration can lead to successful $Caf{\acute{e}}$ interior design for specific target customers.

피혁유물은 온·습도, 빛, 충 균 등 다양한 환경요인에 의해 복합적으로 손상된다. 본 연구 결과, 피혁은 원피의 종류에 따라 화학적 조성에 차이가 있어 같은 환경에서도 손상정도가 다르다는 것이 확인되었다. 자외선 열화에 따른 전체적인 색차 및 광택도 변화 및 변색은 우피, 양피, 돈피의 순으로 심하게 관찰되었다. 또한, 피혁은 단기간에는 습도에 관하여 안정적인 결과를 나타났으나 고습의 환경이 지속된다면 곰팡이나 미생물이 발생되기 쉬우므로 주의해야 한다. 본 연구는 피혁유물을 이해하고, 보존환경기준을 제시하여 향후 피혁유물의 보존관리 방안을 수립하는 데에 있다.

The purpose of this paper is to find out the investigation of overseas case in Street Furnitures of Public Design. Thus this research regions select among the waterfront cities; Tokyo/Yokohama(Japan), Nies/Cannes(France), Shanghai(China), Vancouver(Canada), in addition to the city of art and romance; Paris. Above all, it is necessary to study concept of public design and definition of street furnitures. The survey data collected from forenamed cities and the items of street furnitures are various installments such as kiosk, bench, bollard, litter-bin, sign board, toilet, bus/taxi station, fence, shelter, lighting column, fountain, telephone-booth, clock-tower, automaton, bicycle stand, playing object etc. In this study street spaces are analysed that is related to regional surroundings and pedestrian's culture. Consequently, design trend of street furniture in foreign case analysis are going into thoroughly modern image as well as checking of form, color, material and maintenance system. According to the above findings, this paper will provide basic data for establishing of the street furniture and improving of public design to the regional citizen, local government officials and regional experts.

적조란 유해조류 대 번식으로 바다물의 색깔이 변하는 자연현상이다. 적조의 피해가 증가함에 따라서 적조에 대한 많은 연구가 이루어지고 있다. 그러나 자동으로 적조류를 분류하는 연구는 미흡한 실정이다. 적조류는 영상 객체를 일치 할 수 있는 기준 중심 특정이 없기 때문에 인식이 어렵다. 이 때문에 기존이 연구들은 단순히 몇 종류의 적조류 만을 분류에 이용하고 있다. 본 논문은 주성분분석과 영상 객체의 원형율을 이용한 새로운 적조류 인식 방법을 제안한다.

This study has been conducted to find out the characteristics of the form and the color of make-up in Oriental traditional plays by comparing the characteristics of Hahoe masque, which is one of Koran traditional plays with those of Chinese Peking Opera and Japanese Noh plays. The object of the study was confined to the make-up of women players. The distinguished characteristics of women make-up of oriental traditional plays are as followings. First, the make-up of woman players in Korean Hahoe masque adopts mask make-up and expresses the mental state of players very realistically. Second, the women players in Chinese Peking Opera wear face make-up and it is beautifully expressed but not exaggerated. Third, most of Japanese Noh players wear face make-up. However, only women players wear mask make-up so that they might express non-realistic mood. Overall, the women players in Korean Ha-hoe masque adopt mask make-up, Chinese Peking Opera face make-up, and Japanese Noh both mask and face make-up.

The Hanji dyed with persimmon juice were useful goods in the past, but they are not widely used nowadays despite of their many strong points such as antibacterial and water-resistant properties. The object of this study is to provide useful data for developing new products by using them. We dyed traditional Korean hand-made papers (Hanji) with colorants extracted from fruits of Diospyros kaki and investigated the effect of various dyeing factors (mordant, mordanting method, pH of dyeing solution, light exposure time etc.) on optical and mechanical properties of the dyed Hanji. Changing mordant affected the color of dyed Hanji. The dyed Hanji after-mordanted with Cu mordant had the highest K/S value and showed the deepest yellow and red shade. The best mordanting method was an after-mordanting. The K/S value of dyed Hanji increased with decreasing pH of dyeing solution. The tensile index and size degree values of the Hanji were increased after dyeing.

This paper presents an emotion recognition and its expression system of an intelligent robot like a home robot or a service robot. Emotion recognition method in the robot is used by a facial image. We use a motion and a position of many facial features. apply a tracking algorithm to recognize a moving user in the mobile robot and eliminate a skin color of a hand and a background without a facial region by using the facial region detecting algorithm in objecting user image. After normalizer operations are the image enlarge or reduction by distance of the detecting facial region and the image revolution transformation by an angel of a face, the mobile robot can object the facial image of a fixing size. And materialize a multi feature selection algorithm to enable robot to recognize an emotion of user. In this paper, used a multi layer perceptron of Artificial Neural Network(ANN) as a pattern recognition art, and a Back Propagation(BP) algorithm as a learning algorithm. Emotion of user that robot recognized is expressed as a graphic LCD. At this time, change two coordinates as the number of times of emotion expressed in ANN, and change a parameter of facial elements(eyes, eyebrows, mouth) as the change of two coordinates. By materializing the system, expressed the complex emotion of human as the avatar of LCD.
