두 종류의 천연섬유, 즉 면섬유와 목분을 이용하여 폴리프로필렌 - 천연섬유 복합재료를 제조하고 혼합가공시 유변학적 특성과 열적특성을 고찰하였다. PP/천연섬유 복합재료에서 천연섬유의 함량이 증가함에 따라 토오크 값이 상승하였고, 면섬유의 경우 낮은 체적 밀도로 인해 목분 복합재료보다 높은 토오크값을 나타내었다. PP의 MI에 따라서는 낮은 MI의 PP/천연섬유 복합재료에서 더 높은 토오크값이 관찰되었다. X-선 회절분석과 시차주사열분석을 통해 천연섬유의 함량이 증가될수록 PP/천연섬유 복합재료의 결정화온도는 상승하나 결정화도는 감소함이 확인되었다.

This paper intends to examine how Fringe, which is in an inseparable relationship with modern fashion, has been changed and what characteristics it is expressed to have in fashion on the basis of its formative property expressed in modern fashion. In order to empirically analyze Fringe, this paper analyzed a total of 346 Fringe of every type that were generally found in the worldis four biggest collections, from 2006S/S to 2011S/S. This paper found some methods Fringe is made, which are: using a snagged fabric or knit as it is; intentionally snagging or tearing a fabric to make the effect of being snagged; knotting the tail or the edge of clothes, and then, macram$\grave{E}$; and cutting leather or suede, which canit be snagged easily, and making Fringe strands. Fringe strands which are made in the above ways are made into a band and then, attached, or Fringe strands, a feathers, a comb, or beads are attached one by one. Or a tassel is independently or consecutively applied to clothes or ornaments, which are expressed in the form of fringes. Threads, strings, leather, suede, metals, plastics, raffia, horsehair, paper, beads, pearls, crystals, or felt were used for rich texture or unique visual effects. Colors of various brightness and chromas were used in consideration of materials. Through the effects of sameness, similarity, contrast, harmony and gradation with colors of clothes, emphasis or unified harmony was expressed. The expressive characteristics of Fringe, which were found in the modern fashion through those formative characteristics, were organic rhythmical beauty, handicraft decorative beauty, and folksy natural beauty.

The study aims to examine consumer awareness of green fashion products and demographic characteristics by subdividing environmentally conscious consumers of such products in the current domestic fashion market. It then compares the result with the characteristics of environmentally conscious consumers studied by 1999 in order to understand the trend of the consumer group in the fashion market and to promote the use of green fashion products. Marketing strategies for green fashion products suggested by the study are as follows: First, fashion firms are required to develop and publicize shops selling recycled or second-hand clothing that environmentally conscious consumers show constant interest. For instance, clothing patterns may be developed to enable consumers to make their kids' clothing easily at home, and various garments made from recycled materials may stimulate environmentally conscious consumers' desire to buy. Particularly, advanced technologies should be developed and publicized to manufacture garments that can excel existing ones made of normal materials in their features in order to satisfy consumers' interest in clothing made from recycled PET bottles. In addition, various natural dyes should be developed to decrease water pollution. Second, it seems imperative to develop clothing made of recycled knitted apparel that attracts consumers' interest more than ever, fashionable multi-purpose clothing, and environmentally friendly materials. As the use of natural fur or leather can cause the endangerment of wild animals and the destruction of the ecosystem, synthetic fur or leather may be used to develop sophisticated products with the same texture as real ones to attract environmentally conscious consumers' interest.

The purpose of this study is to investigate effects of natural incense on the preservation of paper- and textile-based remains and the kinds and applications of natural anti-insect incense by reviewing relevant literatures of the ancient times. There are few ancient literatures of incense published in Korea. The researcher deducted how incense was used in this nation through reviewing verses contained in ancient literatures and medical books. In contrast, the kinds and applications of anti-insect incense used in China, where incense culture prospered, were investigated here through reviewing technical books about incense published during the Song(宋) and Ming(明) periods, $\ll$Incense record(香譜)$\gg$, $\ll$Chen's Incense record(陳氏香譜)$\gg$ and $\ll$Incense record(香乘)$\gg$. There were several methods of keeping clothes better from insects. In relation, how to use anti-insect incense varied in accordance with main materials of clothes, paper, textile, leather and others. Cymbopogon dstans(芸香), Brassica rapu var and Incarvillea sinensis(角蒿) are anti-insect incense which were used for paper. Anti-insect incense for textiles is classified into single and mixed incenses depending on whether only one kind of incense was used or more than seven kinds of the substance. Acori rhizoma(菖蒲), Capsella bursa-pastoris(薺菜花), Lactuca sativa L., Erigeron canadensis(莽草), Stemona japonica(百部) and Moschus sifanicus(麝香) are single anti-insect incense which were used for textile. While, the latter was called. ‘Yi Xiang(衣香)’ is mixed anti-insect incense which was used for textile. Artemisia asiatica(艾葉) and Zanthoxylum schinifolium(花椒) are anti-insect incense which were used for leather. Angelica dahurica(芳香) and Bamboo are anti-insect incense which were used for others. There were three main methods of using incense to prevent insects, that is, diffusing incense's strong scent and ingredients, exposing to smokes from burnt incense and washing with incense-boiled water. Diffusing incenses had a strong scent and antibiotic ingredients, which were put between books or clothes or into a storage box without being processed. If necessary, however, they were processed into rough powders that were in turn used singly, or otherwise mixed for a stronger scent and better insect elimination. Exposing to smokes from burnt incense was done as follows. A clothes was put on 'Long(籠)' underneath which there was a boiling water. The clothes was humidified by the water and then exposed to smokes from burnt incense. 'Long(籠)' had been long used since it was manufactured in the QinHan(秦漢) period for the first time. A local literature, $\ll$Koryo TuGing(高麗圖經)$\gg$ shows that in the Koryo(高麗) period, BoShaLu(博山爐) were used as a means of exposing clothes to smokes to prevent moths, similarly to China. Washing clothes with incense-boiled water was more effective in removing lots of worms and germs from clothes, but leaving the scent and ingredients of the used incense and maintaining the effect of anti-insect.

This research was carried out to find the mordant effects by Tara and Myrobalan as natural tannins on the cow leather dyed with Lac powder. The cow leathers were treated with Tara, Myrobalan, Al, Cu, and Fe mordants by changing treatment orders. It was examined for K/S value, surface color changes, and color difference. The K/S value generally has higher Myrobalan than Tara, and pre-mordant than post-mordanted condition. Cu is the strongest among the three mordants. As a results of the treatment order, the K/S value is higer in pre-tannin-mordant agent than in pre-mordant agent-tannin. In the post mordant, K/S value is higher in mordant agent-tannin than in tannin-mordant agent. The color difference and color factors such as H, V and C were various according to the mordant agents, treatment orders and mordant methods; and surface colors of dyed cow leathers were R and RP. It was difficult to find some significant means of mordant orders.

The hitherto existing gap in the field of chromatographic methods has been filled by the direct coupling of a suitable oven (TAS-oven) with TLC. The sample to be examined is heated either isothermally or linearly within the temperature gradient of $50{\sim}450^{\circ}C$. The volatile and/or thermolytically evolved substances are fractionated on the TLC-layer and subsequently chromatographed under standard conditions. Transport mechanisms from the sample to the TLC-layer, applications of the TAS-procedure and further developments are discussed. Thermofractography, developed from the TAS-procedure, is demonstrated on different groups of natural substances such as alkaloids, amino acids, nucleic acids. nucleosides, nucleotides, triglycerides and other lipids, pyrone glycosides and aglycon. Experimental work and results on the thermolysis of macromolecular natural and synthetic substances, natural polyphenols, tanning agents and leather and the possibilities of differentiating various lignins, carbohydrate and synthetic polymers are reported. Further, it is shown that classical reactions in the microgram range, e.g. zinc dust distillation, sulphur-and selenium dehydrogenation and catalytic dehydrogenation, can be coupled directly with TLC. Also described is a method which allows to investigate the gaseous compounds evolved during thermofractography in the range of up to $450^{\circ}C$. Thermal procedures coupled with TLC open up the following new possibilities for chemical microanalysis: fractionated separation of distillable and sublimable components, fractionated thermolysis and carrying out of thermal reactions in the ultra micro range.

There is a commonality between Frank Lloyd Wright and Charles Rennie Mackintosh in that they created the new patterns of geometric Art Nouveau from the late 19th and early 20th centuries. This study compares the furniture of Wright and Mackintosh who had significant impacts on the development of modern design for each of the periods divided by their design feature to find the individualities and similarities of their design. It is an analytical approach with an accurate understanding of the design trends of the Art Nouveau era. The results of the furniture comparison are as follows: The finding is that Wright and Mackintosh designed creative furniture in harmony with a specific indoor space, Organic design was well expressed through the selection and use of wooden materials, Based on the understanding of tree characteristics, they did not use detailed decorations, but designed the simple and rigorous forms of furniture with highlighted interest in geometry. As for shape, Wright's furniture in his early days tend to be look largely formal and heavy. Since his debut in Japan in 1905, the furniture design became very sophisticated. On the other hand, Mackintosh's chairs are characterized by plenty of geometric patterns and long back. In many cases, his chairs were designed as part of formative elements in space, not for the purpose of furniture itself. As for materials and colors, Wright used mainly cherry wood. And he also utilized metals colored in olive green, red-brown and others for office furniture. The frames, fabrics and leather used for most of the furniture have natural colors, which are harmonious with spaces. Meantime, Mackintosh used primarily oak and ash trees. He used seat cushions and various colors to make the design of furniture have a sophisticated and simple image. The materials used for seat panel are horsehair, rush, silk and leather. He applied these materials to the furniture by weaving or cutting them.

Bioassay using the marine bacteria, Vibrio fischeri and rotifer, Brachionus plicatilis, and chemical analyses were conducted to assess the toxicity of the various sewage sludges, one of the major ocean dumped materials in the Yellow Sea of Korea. Sludge elutriates extracted by filtered seawater were used to estimate the ecotoxicity of the sludge. Chemical characterization included the analyses of organic contents, heavy metals, and persistent organic pollutants in sludge. Bacterial bioluminescent inhibition (15 min), rotifer mortality (24 hr) and rotifer population growth inhibition (48 hr) assay were conducted to estimate the sludge toxicity. EC50 15 min (inhibition concentration of bioluminescence after 15 minutes exposed) values by Microtox(R) bioassay clearly revealed different toxicity levels depending on the sludge sources. Highest toxicity for the bacteria was found with the sludge extract from dyeing waste and followed by industrial waste, livestock waste, and leather processing waste. Clear toxic effects on the bacteria were not found in the sludge extract from filtration bed sludge and rural sewage sludge. Consistent with Microtox(R) results, rotifer neonate mortality and population growth inhibition test also showed highest toxicity in dyeing waste and low in filtration bed and rural sewage sludge. High concentrations of persistent organic pollutants (POPs) and heavy metals were measured in the samples from the industrial wastes, leather processing plant waste sludge, and urban sewage sludge. However, there was no significant correlation between pollutant concentration levels and the toxicity values of the sludge. This suggests that the ecotoxicity in addition to the chemical analyses of various sludge samples must be estimated before release of potential harmful waste in the natural environment as part of an ecological risk assessment.

두 종류의 천연섬유, 즉 면섬유와 목분을 이용하여 제조한 폴리프로필렌 - 천연섬유 복합재료의 혼합가공시 유변학적 특성과 열적특성에 미치는 상용화제의 영향을 고찰하였다. 상용화제로는 무수말레인산이 그래프팅된 폴리프로필렌 공중합체를 사용하였다. 천연섬유의 종류에 관계없이 상용화제를 첨가할 때, 전반적으로 상용화제의 함량이 증가함에 따라 토오크 값이 상승함이 확인되었다. 또한, 시차 주사 열량계(DSC)와 X선 회절분석(XRD)을 통해 상용화제의 첨가시 복합재료의 결정화도가 약간 상승함이 확인되었다. 섬유의 종류에 따른 영향은 거의 관찰되지 않았으나, 혼합시 유변학적 물성, DSC 및 XRD 결과에 의하면, 면섬유의 경우가 목분보다는 PP-g-MAH와 더 나은 상호작용을 보이는 것으로 생각된다.
