This paper investigated the costumes of young girl dancers in Yon wha dae moo(연화대무: Lotus Stage dance) which were documented on the Ak-hak-guae-bum(악학궤범: Protocol of music) and the Jin-yeon-eui-guae(진연의궤: Archives of Royal Feast). The fashion of the costumes can be changed into three phases, based mainly on the changes of Hap-rip(합립: silk hat), Dan-eui(단의: long jacket) and Sang(상: apron type skirt). In the first phase the costume consisted of Hap-rip, round neck-line Dan-eui and tiered skirt decorated with pleat and Yu-so(유소: decorated cords). In the second phase. it consisted of Hap-rip, v-shape neck-line Dan-eui and skirt without pleat. In the third phase, it consisted of Yeon-wha-gwan(연화관: Lotus shape cap), round neck-line Dan-eui of later era and skirt with pleat and Yu-so. Yon-wha-dae dance appears to be adopted from Ja-ji-mu( 자지무: chinese dance) that originated in West and Central Asia. In both dances. young girl dancers danced mainly jump and spin. The costume of round neck-line Dan-eui seems to have been affected by the fashion in Dang Dynasty when young girls loved to wear Dan-ryung(단령: male coat with round neckline). And it satisfied the need of mobility for the dance which was Performed mainly with jump.

There have been many attempts to reduce the cost of transportation. Especially, drag reduction of heavy vehicles has enormous influence on energy saving by reducing the driving power of the vehicles. In this study, the effects of drag-reducing additive devices such as side skirt, boat tail and cab-roof fairing on the drag reduction of a 5 ton truck model were experimentally investigated. The aerodynamic performance of these flow-control devices attached to heavy vehicle was evaluated through wind tunnel test. In addition, flow patterns around the truck model were visualized by using smoke tube method. The drag coefficient is reduced by up to 5.7%, 7.16% and 22.2% by the side skirt, boat tail and cab-roof fairing, respectively. The interactive effect of the side skirt and boat tail was also investigated.

첨단 공정이 필요한 반도체와 LCD, PDP, LED 등의 디스플레이 및 IT 부품을 제조하는데 필요한 장비의 고성능화와 작업환경의 고청정화에 따른 초고진공펌프의 수요 확대와 앞으로 전개될 한-미 FTA에 따른 시장 확대로 인해 크라이오펌프의 국산화가 시급한 실정이다. 고성능 크라이오펌프를 만들기 위해서는 냉각판을 극저온으로 냉각하기 위한 극저온 냉동기 개발도 중요하지만 냉각판(cryoarray)에 최대한 많은 분자를 포획시키는 것 또한 최우선적으로 고려되어야 할 사항 중 하나이다. 이에 본 논문은 크라이오펌프용 냉각판의 기체분자 포획능력에 대하여 연구하였다. 냉각판의 분자포획능력의 해석은 형상계수법(view factor method)을 이용해 수행하였다. 해석에 이용한 냉각판은 현재 상용화된 모델들 중 원형 중앙판에 45$^{\circ}$ 하향 skirt가 달린 형태이며 8장의 냉각판이 일정한 간격을 두고 아래쪽으로 적층되어있고 이를 기본 모델로 하여 skirt의 형상이 다른 3장의 냉각판을 가진 네 가지 모델을 해석하였다. 해석에 이용한 냉각판의 기체분자 포획능력이 구속된 형상에서 얼마나 우수한가를 알아보기 위해 크라이오펌프의 입구 직경과 냉각판 중앙 원판의 직경비, 냉각판 사이의 거리, 그리고 skirt의 길이를 변화시켜가며 극저온 냉각판에 직접 응축되는 typeII가스와 흡착제가 도포된 부분에 의해 흡착되는 typeIII가스로 분류하여 해석을 수행하고 그 결과를 비교, 분석하였다. 크라이오펌프의 입구 직경과 냉각판 중앙 원판의 직경비가 증가함에 따라 typeII가스와 typeIII가스 모두 기체분자 포획능력이 증가하며 극저온 냉각판 사이 거리의 변화에 따른 기체분자 포획능력은 typeII가스의 경우 극저온 냉각판 사이의 거리가 증가할수록 증가한다. 하지만 typeIII가스는 모델 A, C의 경우 증가하고 모델 B, D의 경우 증가하다가 다시 약간 감소한다. skirt 길이 변화에 따른 기체분자 포획능력은 두 가스 모두 skirt 길이가 증가함에 따라 점점 급격하게 증가하고 모델 B, D는 나머지 두 모델에 비해 큰 값을 갖는다. 기체분자 포획능력을 해석한 결과를 실제 배기속도와 비교할 경우 절대적 수치로써의 비교는 어려우나 각 모델의 형상의 차이에 의한 상대적인 비교는 가능하다.

The purpose of this study is to identify the effect of three clothing cues(jacket color, skirt color, and tone of dress) on female impressions. The experimental materials developed for this study are a set of stimuli and response scales. The Stimuli are If color pictures manipulated with three clothing cues by drawing. The 7-point scale designed for visual evaluation of female impression formation includes 24 bipolar adjectives. The subjects were 192 undergraduate female students in Jinju city. The results of this study are as follow: As analyzing the impression of female figure by the jacket color, skirt color, and tone, three factors including youth${\cdot}$activity, attractiveness, and visibility were identified. Among these factors, youth${\cdot}$activity and attractiveness were proved to be more important. Some interaction effects of clothing cues were found. Jacket color and tone had significant effects on the impression of visibility. The combination of skirt color and tone had significant effects on youth${\cdot}$activity, attractiveness, and visibility.

The piston of a marine diesel engine works under severe conditions, including a combustion pressure of over 180 bar, high thermal load, and high speed. Therefore, the analyses of the fatigue strength, thermal load, clamping (bolting) system and lubrication performance are important in achieving a robust piston design. Designing the surface profile and the skirt ovality carefully is important to prevent severe wear and reduce frictional loss for engine efficiency. This study performs flexible multi-body dynamic and elasto-hydrodynamic (EHD) analyses using AVL/EXCITE/PU are performed to evaluate tribological characteristics. The numerical techniques employed to perform the EHD analysis are as follows: (1) averaged Reynolds equation considering the surface roughness; (2) Greenwood_Tripp model considering the solid_to_solid contact using the statistical values of the summit roughness; and (3) flow factor considering the surface topology. This study also compares two cases of skirt shapes with minimum oil film thickness, peak oil film pressure, asperity contact pressure, wear rate using the Archard model and friction power loss (i.e., frictional loss mean effective pressure (FMEP)). Accordingly, the study compares the calculated wear pattern with the field test result of the piston operating for 12,000h to verify the quantitative integrity of the numerical analysis. The results show that the selected profile and the piston skirt ovality reduce friction power loss and peak oil film pressure by 7% and 57%, respectively. They also increase the minimum oil film thickness by 34%.

The purpose of this study is to investigate the effect of tone-on-tone coloration on the visual images of traditional Korean dress. The materials in the experiment developed for this study were made up of various stimuli and the response scales for each stimulus. The stimuli were 48 color pictures with various combination of colors, in which the tones of jackets and skirts were manipulated by computer drawing. 24 bi-polar adjectives, each of which was graded into seven in its degree, were used to evaluate each image. The subjects were 576 female students in Jinju City. This experiment was based on the $3{\times}4{\times}4$ factorial designs: color (red, yellow and green), jacket tone (vivid, light, dull and dark) and skirt tone (vivid, light, dull and dark). The results of the study can be summarized as follows; Impression factor of the stimuli consisted of the 5 different dimensions - youthfullness and activity, attractiveness, gracefullness, visibility, and tenderness. The colors and the tone of jackets and skirts used in this experiment influenced 5 impression dimension by interaction of two valuables or working independently. Yellow and green with vivid or light tone had an effect on the formation of youth and activity image, and dark-light combination had an effect on the formation of attractiveness image. In case of green color, light tone of a jacket and vivid or dull tone of a skirt affected gracefulness, while yellow has no impact on visibility image regardless of skirt tone. Red and yellow with vivid or light tone were a factor to decide tenderness.

Many communication systems require bandpass filters with sharp skirt frequency characteristics in order to avoid the interferencce, which results in more order in the filter design. However, because of the limited Q values bandpass filters made of small sized ceramic resonators suffer from relatively large ripples at the band edges as the order of the filter increases. In order to compensate the large ripples while maintaining the sharp skirt frequency we propose a new RF amplitude equalizer. The equalizer made of two pole bandpass filter and an amplifier whose amplitude characteristics are the reverse of those of the bandapss filter. At the cellular band 9-pole bandpass filter with 10 MHz bandwidth exhibits 3 dB ripple when 8mm*8mm ceramic coaxial resonators are used. We added the RF equalizer to this filter and the flatness is improved as less than 1 dB.

In the Joseon Dynasty, a Court Ladies' full dress was Slanted by the Ming Dynasty. Since the Ming Dynasty had declined, a Court Ladies' full dress, Jeok-ui began to be made by the Joseon Dynasty. It was based on the Chinese Court Ladies' full dress, Desam, but it became Joseon's own style, which was different from the Chinese one. The formula of Jeok-ui was completed in the time of King Yongjo. Since then, Jeok-ui for big ceremonies was called Bub-bok. It was recorded on the Regular rule of Sang-uiwon. The color of Jeok-ui was departmentalized for the wearer; red one for the Queen, bluish black one for the Crown Princess, and purple one for the Queen mother. There were some differences between Jeok-ui for feasts and for big ceremonies. In the case of Jeok-ui for big ceremonies, the pattern of Hyung-bae for the Queen was a dragon with five claws, and for the Crown Princess, a dragon with four claws. On the other hand, in the case of Jeok-ui for feasts, the pattern of Hyung-bae was phoenixes for the Queen, Crown Princess and the Queen mother. The number of embroidered round badges, which were attached to Jeok-ui, was 51 for big ceremonies, and 36 for feasts. The skirt for big ceremonies was a Jeonang-ut-chima with dragons pattern for the Queen, and phoenixes for the Crown Princess. The Queen's skirt for feasts was a Jeonang-ut-chima with phoenixes pattern, and the Queen mother's also. The Crown Princess' was a double skirt with phoenixes pattern. The pearls were not decorated on the shoes for big ceremonies, but shoes for feasts had six big pearls fer decoration. When the royal woman wore Jeok-ui for big ceremonies, it was prepared for Kyu, Pe-ok and belt with jade. But those were not necessary for Jeok-ui for feasts.

The results from the consideration of this are as follows. 1. Dan dynasty has been 10-parts dancer and musician group for courtesy ceremonial meetings of ancient china. 2. Except ceremonial dance and music common dance and musics performed it in front of common peaples meetings. 3. After unification of Dang dynasty many commercial men and artist come frome western of China threfore influenced their costume habbits and behabiers from royal families costumes and common peaples costume without concern of that one's social position. 4. As the people who lived in thewest areas of old china there characterestics of the costumes are open breast jacked breast laped long skirt long scarf long boots narrow sleeve jackets patterend textilles(for womens) round neck narrow sleeved one-pies dress belt, long boots. patterend textiles(for mens). 5. Dancer's Costumes mode are as follows: 1) For females : high hair style, Twin 'high hair style. jewrery decorated hat bird's hair decorated cap. ribons. 2) For mens: Bok-doo. Hokongdu 6. Except traditional old china dancer dress they have many interested dancer dress for instance dang dynasty's 'Ye-sang woo yui dnace' dancer dress is very elegant and interested hip level jacket has peacoak wing shaped sleeves and long skirt has try angles shape attached apron this dancer dress begins wi-jin nam·book-dynasty. 7. Men dancer dress is just head cap bok doo long narrow sleeved one-pies dress.
