The purpose of this study was to compare the characteristic of Chanel style between modern and postmodern period. The documentary research method was used for this study. The modem period was limited from around 1920 through 1939 and the postmodern period from 1990 through present for this research. The results were summarized as follows: The characteristics of clothing style in modem period were 1) the preference of slim & straight body figure as ideal one and slim & straight clothing silhouette, 2) the high fashion image for the elite by simple & basic design, 3) the emphasis on the harmony by the unity, 4) the tendency of eliminating ornaments on clothing, 5) the discontinuation of traditional way of dress code & style, and 6) the modern style. The characteristics of clothing style in postmodern period were 1) the emphasis on erotic aspects of female body and sexy design, 2) the popularization of high fashion and certain social group's fashion, 3) the tendency of harmony by mix-match, 4) the preference of ornaments in clothing, 5) the preference of retro-fashion, and 6) the continuation of modem style.

The present study is conducted to identify a better design and optimal number of Francis runner blades for sediment laden high head micro hydropower site, Tara Khola in the Baglung district of Nepal. The runner is designed with in-house code and Computational Fluid Dynamics (CFD) analysis is performed to evaluate the performance with three configurations; 11, 13 and 17 numbers of runner blades. The three sets of runners were also investigated for the sediment erosion tendency. The runner with 13 blades shows better performance at design as well as in variable discharge conditions. 96.2% efficiency is obtained from the runner with 13 blades at the design point, and the runners with 17 and 11 blades have 88.25% and 76.63% efficiencies respectively. Further, the runner with 13 blades has better manufacturability than the runner with 17 blades as it has long and highly curved blade with small gaps between the blades, but it comes with 65% more erosion tendency than in the runner with 17 blades.

The aim of this study is to examine the tween generation's (11 to 15 years-old) clothing purchase tendency. Based on the questionnaire, the data were collected from 187 elementary school students(11 to 12 years-old) and from 293 middle school students(13 to 15 years-old) in Jeonbuk. The data were analyzed with the factor analysis, Chi-square analysis, t-test, F-test. The research shows: the tween generation rarely if ever buy their clothing by themselves, and they usually accompany their mothers when they purchase their clothes. In the 'size fitness', girl tweenage group prefers a perfect fit to an easy one. But boy tweenage group shows a different tendency from them. In the 'fashion adaption', the tweenage group of 13 to 15 year-olds responds in a sensitive way. The 'style', 'design' and 'color' of clothing are the most decisive factors in their purchasing trend. Especially, the boy tweenage group prioritize the factors in the order of 'brand value', 'price' and 'trend'.

Since modernization period thru Japanese colonial era the modern architect began to play a important role for Korean housing architecture. So called 'House as an Art Work', detached houses by prominent architects, belong to a meaningful sector in Korean modern housing architecture. The harmony with tradition was always big issue for such works. This study aims to understand how paradigms for tradition were interpreted with the changes of the time. The analysis showed various tryout by architects, that concretize traditional characteristics in their work. For example, traditional lifestyle were clearly reflected in the floorplan during 30's and 40's. In the 70's building mass and formative roof design were emphasized to present traditional image. As well as it represented primitive esthetic and vernacular decoration. In addition, expressive tendency, that demonstrates korean sentiment through material and its texture, got a preference. Since latter half of 80's some traditional architectural elements were modernized and space characteristics were newly created from acculturation. Furthermore the philosophy of "Subdivision of building wings and Emptiness" follows this trend. This type made a courtyard and connected articulated building masses each other. "Sympathy with Nature" were most essential for a traditional houses in contrast with western architecture. Many architects today make various method to bring nature into interior space and to contemplate nature In the house. Such kinds of adaptation to tradition could be understood as a unique process to manifest identity of Korean modern houses.

본 논문에서는 높은 풍량을 갖는 임펠러 형상 최적 설계를 위하여, 블레이드 형상이 임펠러의 성능에 미치는 영향을 파악하였다. 먼저 임펠러 성능에 큰 영향을 미칠 것이라 판단되는 블레이드 개수, 각도, 길이를 설계변수로 선정하고, 실험계획법에 의거하여 정한 설계 수준에 따라 각기 다른 27가지 임펠러 형상을 설계하였다. 그리고 블레이드 형상 변화에 따른 임펠러 성능변화를 예측하기 위해 ANSYS CFX로 유동해석을 진행하였다. CFD 결과, 블레이드 개수 50개, 각도 $6^{\circ}$, 길이 5 mm 조합의 임펠러 형상에서 가장 높은 풍량이 발생되었다. 마지막으로 해석 결과를 바탕으로 3D프린터를 이용하여 기존 임펠러 형상과 시험군 임펠러 형상을 제작하였고, 블로워의 토출구에서의 유량을 측정하여 CFD 결과와 비교하는 검증 실험을 진행하였다.

현대의 고성능 전투기는 공력성능 및 조종성능의 향상을 위하여 대부분 세로축 방향으로 항공기를 불안정하게 설계하는 정안정성 완화 개념을 채택하고 있다. 항공기는 비행제어법칙에 필요한 피치, 롤, 요우각속도, 수직가속도와 같은 항공기 상태정보를 각속도(RSA: Rate Sensor Assembly)와 가속도센서(ASA: Acceleration Sensor Assembly)로부터 획득한다. 항공기에 적용되는 센서는 항공기의 안전을 보장하는 최소한의 허용 가능한 측정 오차를 갖지만, 잡음, 오프셋 등과 같은 허용 범위내의 오차로 인하여 원하지 않는 항공기 운동을 발생시킨다. 비행시험 결과, ASA의 허용 범위내의 측정 오차는 1g 수평비행시에 원하지 않는 기수 숙임 현상을 일으켰다. 본 논문에서는 이러한 오차로 인하여 발생하는 기수 숙임 현상을 개선하기 위해 1g 수평비행 조건에 피치자세각 궤환을 세로축 제어법칙에 적용하였다. 비행시험 결과, 피차자세각 궤환은 1g 수평 비행 시에 기수 숙임현상을 제거하고 항공기의 기본적인 안정성에는 영향을 미치지 않는다는 것을 확인할 수 있었다.

Digital media changed not only our lifestyle and sense of value but also art and space design, and development of technology will accelerate the alteration. It provided limitless possibility and inspiration to art, architecture and design. In this 'image' era, media communicate with us mostly in visual method, which gets to he realized by visual interface. The purpose of this study is to analyze the tendency of visual interface of contemporary interior design cases in the standpoint of digital media characteristics and suggest directions for future space design. The characteristics of digital media and interface are defined, and how the concept unfolded in art, design is also discussed. In interior design, the concepts come out as various types of visual interface, showing the characteristics of composition of material and immaterial, interaction between visual information and space users and among users, realization of cyberspace and simultaneous coexistence of multiple space-time multi-layer.

In late years, the tendency to shift the design language of electronic circuits from HDL to C-based languages of C/C)1 and so on is strengthened. The current of adopting these software languages thrives by necessity to solve the problem peculiar to HDL that verification of design is difficult. When we use C-based languages, we can describe the design by higher abstraction degree, mount the design as both hardware and software finally and so that express the design part which is not made clear at early stage the same one language. Therefore, the flexibility of design very improves, the design work in environment the range of applying the whole systems become possible. This paper introduces example at having applied C-based languages in image processing LSI design and describes that the design technique of C-based languages is effective for the system design.

This study was to investigate the preference tendency by detail and material preference of summer one-piece dresses for the children, and evaluation standard of children's wear in purchasing one-piece dresses as an object of mothers who have girls as buying representatives of children's wear in order to supply real information of design about the one-piece dresses for the girls in accordance with the consumers' demands. The results of this study revealed that the one-piece dress was favorite one to them in purchasing their summer wear. This study showed tendency that the more the mother's fashion interest was, the more the mother's preference on the one-piece dress was. As to the material preference of one-piece dress, it preferred the natural fiber to the synthetic fiber much, and the preferred customer order in purchasing one-piece dresses for their children was analyzed as activity, material, design collar, and pattern. As to the preference by form factor of one-piece dress, it preferred A-line silhouette in the silhouette, natural waist in the waist position, 5~7cm from the knee in the length of one-piece dress, and flared skirt in shape of skirt. The preference on the collar type was soutien collar, and the preference on the neckline type was round neckline. In addition, the preference on sleeve form was shirtsleeve, and the preference on trimming was lace trimming.
