This study's purpose is to find the ancient costume of the folk song's words on Dunhuang manuscripts in the background wass-carvings sculptures and several art works. Dunhuang had played the part of major route between ancient China and Europe. It is located on kam-suksong the west of China. 1. In the aspect of costume arrangement hair Styling is represented by Naegagyo, Wangyesa, Kyongburak, Bonkwyun, Pogurak, Chonsonja, Namgaja, Tongson-ga, Ojesa, Chanboja in Dunhuang manuscripts. tugue is sim-ilar to Sabyokkwanja in Naegagyo as of that time these kinds of Kwan-ja was very popular. It was told that emperor's wife concubine and maid of honor would wear kwnaja favorably. And the kinds of Tugeu is PuyongKwyunkye, Aangunkye, Chunkye from Kyuwanjon except Sangunkye, Ounkye in Dunhuangsa. 2. Jangdaegy is guoted from Kyuw-anjon -A series of the chinese history book-tells us about women's make-up . The narmes of make-up are Hongjang Unjan--g, Yiljang chwejang, Tam-ajang Murgjang, Sanagjang, Light-make up are referred in Naegagyo is included as packjang Besides we can find other make-up skills Huphwaro and Rujang from the Kaewonch onbon-wisa which was Yangkwibi's episodes. We can find the a corpus of song's words about cosmetic custom in Kor-ea. Which is 'Haecho' folk song in the souther-en costal regions 'Jinggum' folk song in Kim-hae regions and so on.... It's words is similar to Dunhuangsa in China. 3. Bichun inherited to China with India Bud-dism art in the middle of Dunhuang wall-pain-tings is one of the important Buddist saint. Sometimes it is painted with Giakchun Its arms of fly-dnacing in heaven with colored belt on body has almost the form of play on the musical instrument, We can see seasily the form in the painting of Buddist ser-mon. It was progressed and changed with the background of chinese traditional culture. When Dang's period came the color was chan-ged lighting dark blue has rhythmical and viv-id power of life. 4. Among the corpus of song's words which express the singers' system and rites of their tradition or habits. Dunhuang manuscripts des-cribes on behalf of the folk song's words in tra-ditional costume. This is following: (1) Naegagyo o sabyokwanja o Chyrasam o Rashang (2) Wangyesa o Sokryugun o Costume for fisher man (3) Bungajang of the chanboja o Ajang (4) Pongkwyun o Chongui (5) Tongsongs o Junofore (6) Namgaja o thin-Rasam (7) Yuchungnang o Hongsam o Sokryugun : The color of red costume (8) Kyongburak o Hongrasam o Sokryugun : Costume for charming woman Therefore traditional costume could be extracted according to the Dunhuang folk song's words out of culture such as learning rit-es three-obedience four-virtues and in-struction. As the same time it reflects ancient China's characteristics directly. I would endeavor to development for the history of the costume furher creative design and participat-ed in research activity with concerns forward continuously.

The park in city, is more than just ecological function, contributes emotional refinement and psychological stability to citizens, and give satisfaction of social and recreational activities to the citizens. And it is the place of leisure and the place to raise up the quality of urban environment. Especially, the neighborhood park among urban parks occupies the most important position as a leisure space for local resident, but it can not perform its purpose and function as a leisure space, due to its too formal and insufficient facilities. This study, approaching from point of physical method, intends to make types through classifying each parks by built-type and installed facilities which affect human-beings, approaching from point of human-beings, intends to make the using-type analysis of park-users, and the questionnaire.By grasping of their requirements regarding to the characters and facilities what they want, willing to present the fundamental data for effective utility-activating method of small-scaled neighborhood park.

It is very difficult to execute the vibration analysis of a huge structure, which takes up much time and expense. In this paper we intend to make the equivalent system of a local vibration system of a huge structure with a view to improving the dynamic characteristics and reducing time and expense. First of all, upper deck structure model is maded. And we perform the vibration analysis by the Substructure Synthesis Method and execute the exciting test for the upper deck structure model, and observe the coincidences of two results to confirm the reliability of the analyzing tools used. To make the equivalent system, we give boundary condition to sub-structure that want to be modified and execute the Sensitivity Analysis Method and the Optimum Structural Modification Method. And we execute the structural modification of the equivalent system.

Recently, the growth of the Internet shopping malls around the world has been increasingly accelerated based on the great advances of IT. Nevertheless, in China the Internet shopping malls have not rewed up relatively. Therefore, this paper has a purpose to discover the factors influencing the vigor of the shopping malls in China and mechanisms on interrelationships among the factors, focusing on customers' trust. To analyze the Chinese Internet shopping mall market from a wider perspective, our research model includes the antecedents from the aspects of shopping mall quality, customer characteristics, environmental features through reorganizing comprehensively various factors considered in the previous studies, and uses customer trust as an intermediate factor and purchasing intention as a dependent factor. It is expected that the implications of this study can help Chinese government agencies related to Internet shopping malls and managers for them make decisions on their policies and strategies effectively.

Korean High Speed Train (KHST) has been tested on high speed line in JungBu site since it was developed in 2002. The data acquisition system was used to test successfully the on-line test for proving the dynamic performance of KHST. The recognition of system vibration mode for railway vehicle is essential to understand the characteristics of design for dynamic system and diagnose the dynamic problems of vehicle system during test and operation. But, up to now, there are the efforts to know the system vibration mode within limit of theoretical field only, not experimental approach with systematic method. The theoretical results are too reliable to apply to real design problem, because it is theoretically based on the homogeneous linear system although the real system have the nonlinear characteristics and vary the environmental conditions. Therefor, in this paper, it is proposed the efficient method of vibration analysis for rail vehicle system and this method apply to KHST to recognize the vibration mode characteristics of it. The results show that this method is able to make the system vibration modes for KHST clear.

The need for more fuel-efficient and lower-emission vehicles has driven the technical development of alternative fuels such as Liquefied Petroleum Gas(LPG) which is able to meet the limits of better emission levels without many modifications to current engine design. LPG has a high vapor pressure and lower viscosity and surface tension than diesel and gasoline fuels. These different fuel characteristics make it difficult to apply it for the conventional gasoline or diesel fuel pump directly. In this study, experiments are performed to get performance and efficiency of the fuel pump at different condition as temperature, rotating speeds, composition of fuel. The characteristics of fuel pump is affected by cavitation due to the variation of temperature and composition.

The aim of this study is to clarify aesthetic values and sociocultural meanings that reappears in contemporary fashion. In order to analyze aesthetic values and symbolic meanings of body decoration, I examined the concepts and expression methods of the body decoration. Also, analyzed external characteristics of expression and its internal meanings that applied in modern fashion. The expressions of body decoration represented in contemporary fashion are classified into direct and indirect methods. The direct method is expressed by tattoos, piercing, henna, make-up and body painting. And, indirect method is expressed by see-through look, body-conscious look and accessories that were utilized its patterns and the material adaptation methods. Such expression of body decoration in the modern fashion was represented into grotesque images and erotic images. The characteristics of grotesque images are abnormal state, hateful animal image and distorted or transformed body and the internal meanings are the pursuit of primitive, exoticism, the pursuit of playfulness, and resistance. The characteristics of erotic images are an exposure of body, see through, body-conscious and androgynous look and the internal meanings are the self-intoxication, naturalism and sexual pleasure.

In the structures of automobiles and ships which have engines for works, the vibration energies generated by the engines are transferred to dissipation parts through the structures which is welded and bolted with beams and plates. The vibration energies generated by resonance frequencies are the reasons of the resonance phenomena. To solve these problems, up to the present, we have studied to avoid the resonance, and add the higher damping characteristics. However, we need to understand the structural energy flows, to design the structures clearly which have the characteristic of welding. The object of this study is to make differences clear in the characteristics of structures which have some welded part on an homogenous flat plate. In this investigation, we study the flows of structural vibration energy experimently, and then, some knowledge for dynamic structural design is obtained.

A binaural filtering method using HRTF DB is generally used to make the headphone-based 3D sound. But it can make some confusion between front and back directions or between up and down directions due to the non-individual HRTF depending on each listener. To reduce the confusion of sound image localization, we propose a new method to boost the spectral cue by modifying HRTF spectra with spectrum difference between front and back directions. Informal listening tests show that the proposed method improves the front-back sound localization characteristics much better than the conventional methods
