This study as one of a series of systematic studies about dancing costumes will compare the costumes of the 16th. 17th century with their normal style of dress. In brief. this study wants people to know about 16th, 17th century court dancing costumes and to understand the culture in the 16th.17th century. From the comparison between the court's dancing costume and the people's clothes, we could get the conclusion as follows. First, pourpoint. chemis, gown, chausses, etc. that people wore were used for the court's dancing costume. While people Pursued the beauty with the ample silhouette. there were used wrinkles. slits. and tailored oblique line-clothes that gave vitality. Second, silk. linen. brocade. etc. that were used for people's chemises were used for the dancing costume. The good quality and beautiful colors of the dancing costume. however. excelled than of the brilliant court's clothes and the people's clothes. Third. the hair style of dancers were very colorful. For example, there were many kinds of hats and furs, corals, etc. that were attached to them on the most of the long curly hair. In summary, for the court's dancing costume, the same type of clothes was used like the people's clothes. There, however, were differences. The slits, tailored oblique line-clothes and shortened skirt gave the activity. There were many decorations symbolizing the nobles' wealth and Power. Especially the use of the decoration of hair and other stake properties was an effective means for expression. The use of personified masks also contributed to the development of the court dance.

최근 들어 곤충을 식품 및 바이오 소재로 이용한 연구가 활발히 진행되고 있다. 그러나 곤충을 이용한 모발 성장 효과에 대한 연구는 아직 미흡한 실정이다. 따라서 본 연구에서는 탈모 예방 및 모발 성장 효과를 가진 새로운 천연물 소재 개발을 위해 갈색거저리 유충 추출물의 항산화 활성 및 모발 성장 촉진 효과를 연구하였다. 갈색거저리 유충 추출물의 항산화 활성 평가를 위해서 DPPH 라디칼 및 아질산염 소거능을 측정하였다. 모발 성장촉진 효과를 측정하기 위해서는 인간 모유두세포(human dermal papilla cell)와 섬유아세포(fibroblast, NIH3T3 cell)를 이용하였으며 MTS assay를 통해 세포생존율 및 세포증식률을 측정하였다. 모유두세포에서 dihydrotesteone (DHT)에 의한 세포사 억제 효과를 확인하였으며, 섬유아세포에서는 tolbutamide (TBM)의 potassium channel blocker 역할에 의한 세포사 억제 효과를 확인하였다. DPPH radical 및 아질산염 소거능 측정 결과 갈색거저리 유충 추출물은 항산화 역할이 뛰어난 것으로 보고된 블루베리와 유사하거나 높은 정도의 항산화능을 가지는 것으로 확인되었다. In vitro 상에서 갈색거저리 유충 추출물을 48시간 동안 처리한 경우, 모유두세포와 섬유아세포의 세포증식을 218% 및 116%까지 증가시켰다. 또한, 모유두세포에서 DHT 처리에 의한 세포사가 갈색거저리 유충 추출물에 의해 억제되는 것을 확인하였으며, 섬유아세포에서는 potassium channel blocker인 TBM에 의해 세포생존율이 감소하였으나 갈색거저리 유충 추출물 처리 시 세포생존율이 정상군과 비슷한 정도로 회복되는 것을 확인하였다. 이상의 결과로부터 갈색거저리 유충 추출물을 이용한 모발성장 및 탈모방지 기능성 소재 개발 가능성을 확인하였다.

이상적인 전송선을 가정하고 도출된 여파기 설계 공식에 의하여 대역여파기를 설계할 경우, 제작된 여파기는 중심 주파수의 이동 및 주파수 특성의 왜곡을 발생시키며, 주파수가 높아질수록 심각한 문제를 야기한다. 이를 해결하기 위하여 본 논문에서는 개별 공진기의 EM(Electro-Magnetic) 시뮬레이션을 기초로 한 새로운 여파기 설계 방법을 제안하였다. 이 방법은 여파기를 개별 공진기로 분리하고, EM 시뮬레이션을 통해 개별 공진기의 리액턴스(reactance) 기울기 및 인버터 상수와 같은 여파기 설계 파라미터를 추출한 후, 이것이 인버터와 리액턴스 기울기로 구성된 인버터-기준형 설계치와 같도록 조정하는 것이다. 이와 같이 조정된 공진기를 조합하여 구성된 여파기는 별도의 조정 없이 목적한 설계치를 만족하게 된다. EM 시뮬레이션 시 이미 선로의 분산(dispersion) 및 불연속(discontinuity) 효과를 고려하였기 때문에 더 이상의 조정이 필요 없으며, 이 방법은 인버터-기준형으로 환원되는 대부분의 여파기에 적용 가능하다. 본 논문에서는 5단 SIR 여파기를 예로 들어 여파기 설계의 전반적인 과정을 설명하였고, 평행결합선로 여파기(parallel coupled line filter) 및 hair-pin 여파기에 확장 적용한 예를 보여 이 방법의 타당성을 보였다.

The purpose of this study is to examine the influence of sociocultural attitudes toward appearance and narcissism on body stress. Questionnaires are being administered to 206 women in their 20's-50's living in Deagu and Kyunbook province. The Frequency, factor analysis, reliability analysis, correlation analysis, regression analysis, ANOVA, and Duncan-test are used for data analysis. Sociocultural attitudes toward appearance are categorized into media appearance internalization and social recognition of appearance. Narcissism factors are found to be leadership/privilege, ostentation, and superiority. Body stress is categorized into 4 factors: weight stress, skin aging stress, body dissatisfaction, and hair stress. Sociocultural attitudes toward appearance was related to the sub-variables of narcissism, and body stress. Media appearance internalization is the sun-variable of sociocultural attitudes toward appearance and has significant effects on weight stress, skin aging stress, and body dissatisfaction sub-variables for body stress. Ostentation, and superiority being the sub-variables of narcissism, have significant effects on weight stress, skin aging stress, body dissatisfaction, and hair stress, the sub-variables for body stress. Ages of women display distinctions between the sub-variables in sociocultural attitudes toward appearance such media appearance internalization, and in narcissism such leadership/privilege, ostentation, superiority, and body stress such weight stress, skin aging stress, body dissatisfaction, and hair stress. This result can be a necessary base line data for adult women's appearance management by examining the influence of the attitude toward the appearance developed from the relationship with people around body stress.

In generally, a high pressure fuel injection pipe has been often used as a fuel supply line in automobiles or other diesel engines. Such conventional high pressure fuel injection pipe, however, has suffered from the problem that is folding and hair cracks created therein. The defects can be locally formed in the inner wall surface of the pipe at the connecting head leading to a flow path when the pipe is deformed by the heading process. In the study, in order to prevent the folding in the inner wall surface of the pipe during the heading process, FE-analysis has been used in the die design.

This study purposed to review the concept and characteristics of subculture theoretically and then to analyze subcultural hairstyles shown in the 20th century's fashion in terms of form, structure, texture, design line and design principle, which were formative factors of beauty art. The range of this study was from the 1950's to the 1990's, during which subcultural hairstyles, which were selected for this study, kept a unique formality as subcultural characteristics of each time were reflected in hairstyles. The hairstyles found in subcultural styles were reviewed as follows. From the formative analysis as the above, it was concluded that layer form was seen most frequently in the subcultural hairstyles. This may be because it has a lot of layers in hair, and enables to make more various forms with a simpler care than other hairstyles so that it is easy to show one's own characteristic or differentiate oneself from others. Thanks to the characteristics of layer form, horizontal and convex were often seen as design lines. As for a texture, straight often appeared. The texture of straight is naturally formed without any care applied on hair. The reason may be that most subcultures refused artificiality. Therefore, the characteristics of subcultural hairstyles may be that hairstyles are transformed into various forms and created into the styles appropriately for individual tastes so as to clearly express one's own idea and thought.

Caveolin proteins are mediators of cell death or the survival of injured cells, and they are inhibitors of various signaling pathways. The expression of caveolin-, which is involved in the protein kinase A (PKA) signaling pathway, was examined in the differentiated mouse vestibular cell line UB/UE-1 after gentamicin ototoxicity. Caveolae in the vestibular hair cell of healthy guinea pigs were observed through an electron microscope. UB/UE-1 cells were cultured at 95% $CO_2$ with 5% $O_2$ at $33^{\circ}C$ for 48 hours and at 95% $CO_2$ with 5% $O_2$ at $39^{\circ}C$ for 24 hours for differentiation. Cells were treated with 1 mM gentamicin, 0.02 mM H89 (PKA inhibitor), and then incubated for 24 hours. Caveolin-1 expression was examined by western blotting and PKA activity by a $PepTag^{(R)}$ assay. Caveolae were observed in the vestibular hair cells of healthy guinea pigs by electron microscopy. Caveolin-1 was expressed spontaneously in differentiated UB/UE-1 cells and increased after gentamicin treatment. PKA was also over-activated by gentamicin treatment. Both gentamicin-induced caveolin-1 expression and PKA over-activation were inhibited by H89. These results indicate that gentamicin-induced caveolin-1 expression is mediated by the PKA signaling pathway. We conclude that caveolae/ caveolin activity, induced via a PKA signaling pathway, may be one of the mechanisms of gentamicin-induced ototoxicity.
