내벽이 유리로 코팅된 스테인레스 스틸 관 및 기타 재질을 이용한 마이크로 컬럼의 제작과 그의 크로마토그래피 응용에 관한 연구 (Ⅱ)
안현주,정원조,An, Hyun Joo,Cheong, Won Jo 대한화학회 1995 대한화학회지 Vol.39 No.11
내벽이 유리로 코팅된 스테인레스 스틸 관, 실리카로 코팅된 스테인레스 스틸관 및 보통 스테인레스 스틸관 등 여러 재질의 관에 C18 (5.mu.) 고정상을 충전시켜 길이 30cm, 내경 1mm 및 0.5mm인 마이크로컬럼들을 제작하고 그 성능을 비교 조사하였다.p-Nitroaniline과 N, N-dimethyl-o-nitro-p-toluidine 및 ethyl-benzene 등을 시험 용질로 사용하였다. 유리 또는 실리카로 코팅된 컬럼이 보통 스테인레스 스틸 컬럼보다 효율이 우수하며 컬럼내면이 거울같이 고와야 정지상 충전이 잘되는 것을 확인하였다. 유리코팅된 경우 내경 0.5mm, 길이 30cm 인 컬럼에 대해서도 이론단수가 10,000을 상회하는 결과를 얻을 수 있었다. We have prepared microcolumns made of stainless steel tubing, glass-lined stainless steel tubing, and silica-lined stainless steel tubing and examined their performances comparatively. The length of columns was fixed as 30 cm, and the I.D.'s, either 1 mm or 0.5 mm. Octadecyl bonded silica paticles $(5\mu)$ were used as the stationary phases. p-Nitroaniline, N,N-dimethyl-o-nitro-p-toluidine,and ethylbenzene were used as the test solutes. The glass-lined or silica-lined stainless steel columns showed better performances than the plain stainless steel column did. The number of theoretical plates over 10,000 were obtained even for the 0.5 mm I.D. (30 cm long) column as long as the glass-lined stainless steel tubing was used.
현대 남성 패션의 섹슈얼리티(Sexuality) 표현 특성
안현주(An Hyun-joo) 한복문화학회 2006 韓服文化 Vol.9 No.2
The purpose of this study is to find out the characteristics of sexuality expressed in the contemporary men's fashion. With the drastic social changes since the 1960s and the demise of aesthetic values prescribed as absolute by classical modernism, contemporary men have strived to reveal their aesthetic desires and to express their own unrestricted sensibility and individuality beyond the socially fixed gender notions. The characteristics of the contemporary expressions of male sexualities can be subdivided into four separate categories. First, recent men's fashion shows transition to body conscious style which reveals masculine body line. Body conscious style of sexuality expression presents masculine image of young healthy body by unexaggerated silhouette, and sensual androgynous and sexless image through the characteristical feminine materials. Second, contemporary men have begun to reveal their concealed sexual attractiveness. They are expressing their masculinity and sexuality through partial exposure of their bodies. Through fashion they are trying to express ideal beauty of human body which has been prohibited by the traditional social notions. Third, recent men's fashion presents new style and atmosphere through the novel coordination of interchanging sexual characteristics of masculine and female fashion styles, and through the new innovative style which breaks the fixed notions of wearing the established garments. These new ways reveal the masculinity of free body oppressed by the traditional formal suit. Finally, contemporary men's fashion expresses male sexuality by partially employing appropriate decorating elements such as feminine colors, patterns, materials, details, accessories, and hair-styles. In spite of the partial employment of feminine design elements, they still preserve their sexual identity as men and express their natural sexuality properly.
