천연물로부터 항균 및 방충작용에 효과적인 물질을 검색한 결과, 목초액과 세신추출물이 강한 생물활성을 나타내는 후보물질로 선발되었다. 천연 항균 및 살충제로서 선발된 목초액과 세신추출물은 자체에 색을 지니고 있어 이들을 이용하여 문화재 보존 처리제로 사용하였을 경우 유기질 문화재 재질에 나쁜 영향을 줄 수 있다. 따라서 본 연구에서는 섬유 재질에 대한 영향을 평가하기 위하여 무염색 섬유 시편과 염색 섬유 시편을 대상으로 두 종의 천연 살충소재를 $28^{\circ}C$ 온도와 70% 습도 조건에서 노출 실험을 실시하였으며, 천연 살충소재 처리 후 6개월 동안 이들 섬유의 색변화를 2주 간격으로 측정하였다. 그 결과 세신추출물의 경우 무염색 섬유뿐만 아니라 천연 염색한 붉은색과 푸른색의 섬유에서 또한 색변화가 크게 나타나지 않았으며, FT-IR spectrum 분석 결과에서도 초기 시편과 비교 시 큰 변화가 관찰되지 않았다. 그러나 목초액의 경우 무염색 면섬유에 있어서 3주차부터 뚜렷한 색변화가 관찰되었으며, FT-IR spectrum 분석 결과에서도 초기 시편과 비교했을 때 특정 파장대의 피크가 없어지는 것으로 나타났다. 그러므로 목초액의 경우 유기질 문화재 보존처리제로 적용할 경우 섬유 재질에 영향을 미칠 수 있어 사용에 제한을 두어야 한다.

In contemporary art, soft materials are used in various forms and ways as a medium expressing contingency beyond a simple nature of materials. In the late 1960's, the appearance of soft sculpture as a refusal of the stereotyped 'Erection' characteristic of traditional sculpture served as an opportunity for more attention to soft materials. Fashion is the reflection of age, and the mirror of society, culture and arts. In other words, soft sculpture and fashion are artistic behaviors in the same context, which have neither been fixed nor erected. This study finds its significance in analyzing correlation between soft sculpture and fashion, and the importance of contingency as artistic expression means in this age when boundaries between genres are obscure, and artistic values are given to fashion. By doing so, it aims to present the direction toward which fashion should face in the future, establishing a new aesthetic consciousness with which more creative and various expressions are available in fashion as well. This study presented as its theoretical background the concept of soft sculpture affected by Marcel Duchamp among representative examples of the contingency that started to appear in art starting in the early 20th century. It also analyzed the soft sculpture appeared in 1960s and the expression methods and features of contingency appeared in fashion after late 1990s through a new approach of piling up, hanging up, and tying, three categories classified by Maurice $Fr{\acute{e}}churet$. Common features of the contingency expressed in soft sculpture and fashion were derived in the analysis, which are intensive effects of energy, values given to physical properties themselves, and esthetics of anti-form.

Ethnical tendency follows the current political, economical, and cultural influence eastwards, highlighting films, architecture and interiors as well as fashion. With this tendency, the ethnic outfits are expressed by various styles. This study analyzes the features of current ethnic styles with 1,535 ethnic image pieces from 2005 S/S to 2010 F/W of Pr${\^{e}}$t-${\'{a}}$-Porte in Paris and Milan. First, 'ethnic' is to refer to the distinct features of an ethnic group or a country. 'Ethnic look' refers to the adaptation or re-arrangement of various ethnic group's traditional costumes, dying, textile, patterns, color, silhouettes, and accessories. Second, the most popular ethnics in the modern fashion is the African style, followed by India, Japan, China, and Latin America in both collections. Third, the proportion of ethnics decreased, 2005 (14.9%), 2006 (12.8%) and 2007 (8.2%). In 2008 the proportion increased again. 2010 (27.3%) and compared 2010 to 2007, it increased by 20%. By season, S/S had 1.4 times more ethnic styles than F/W with the prevalence of African and Indian styles. Fourth, as of 2005, the ethnic style became colorful and went through changes to combine various images. This is from the polycentric tendency of co-existing various styles with a prevalence of low tone and various colors. It also shows warm colors in front to show a sense of nature.

This study is to understand the characteristics of Korean Women's Jeogories in modern times on the changes of its color and coloration over the time. The research was that the characteristics of the costumes produced in modern times ($1890{\sim}2000$) can be categorized into six periods according to the change of times. 1106 women's Jeogories were researched intensively in order to understand them, the conclusions are following: When the Chi-Square Test is applied to conduct cross analγsis of the said six periods divided on the basis of relevant theories, it is found that there is just partial difference in the hues in1890-1959 while there has been a big change in the hues of all Jeogories since 1960. It also seems that such a sudden change In hues took place till the end of the 1970s but there have been no significant difference and no distinct changes in hues sin[e the 1980s. As for color tones, high luminosity and low chroma hues were mainly used in all periods, but low luminosity and high chroma hues have been frequently used since the 1960s. It indicates that the long-used conventional and traditional colors gave way to various colors which were freely applied according to the tendency of individualism In the selection of colors as well. As for the coloration, one-color arrangement was predominant in white clothes while the combination of main color Y and supplementary rotor R was overwhelming in two-color arrangement. After the 1960s, not just the five major rotors but diverse colors, including bluish green, dark blue, were used, even varied patterns for linings.

Strains degrading and decolorizing acid dyes, Nylosan red E-BL 150%. were isolated from natural system, was named as ARK3. The optimal culture conditions of temperature and pH were $35^\circ{C}$, 7.0, respectively. Growth rate of cells in conditions of aerobic shaking more than standing culture conspicuously increased, and optical density of those to strain ARK3 were found as 1.38 and 0.25 after 42 hrs. Decolorization efficiency in batch culture which used as immobilization media to natural zeolite was 15% after 6 hrs, while suspension culture was 5%, also its of immobilization and suspension culture were 90% and 85% after 48 hrs, respectively. Decolorization efficiency of air-lift bioreactor was more than 90% to a dilution rate of $0.038hr^{-1}$, but that was decreased as 70%, when the dilution rate was $0.05hr^{-1}$. Even though at maximum dilution rate of this study, there was not appeared "wash out" phenomienon of biomass. Decolorization efficiency was 97.7% at a dilution rate of $0.025hr^{-1}$, when influent dye concentration was $100mg/\ell$. But if influent dye concentration increased as $150mg/\ell$, even though MLVSS increased, that of treatment water decreased as 93%. Also, when influent dye concentration increased as $200mg/\ell$ and $300mg/\ell$, decolorization efficiencies of treatment water abruptly decreased as 85% and 63%, respectively. Decolorization efficiency was more than 92% to the limit volumetric loading rate of $3.75mg/\ell\cdot{hr}$hr, without regard to variation of influent dye concentration or hydraulic retention time. if volumetric loading rate was more than $3.80mg/\ell\cdot{hr}$, at same condition, decolorization efficiency was lower decrease of retention time than increase of influent dye concentration.entration.
