The purposes of this research are firstly to define the characteristics of movement on the costume, secondly to demonstrate that fine art, expecially in relation to kinetic art, has become a good motif in modern costume de-sign, and thirdly to examin the characteristics of movement as shown in modern costume de-sign. For this study, we selected and analyzed some costume designs among those introduced in fashion magazines, which are Collections, Fashion-Preview, Fashion Show, Collezioni, and L'Officiel that have been issued since 1988. As this research is carried out only through the analysis of pictures, it is not ac-companied by a study on material itself. The result of this study is that the ex-pression of movement on modern fashion can be shown in two ways, one is the inclusive and subordinate movement expressed on the cloth-ing according to the motion of body when they are worn, and the other is the movement caused by the very designs of clothing. And the latter can be also divided in two ways, the illusionistic movement and the actual move-ment. The expression of actual movement is made through the emphasis of direction, rhythm, and dimension of the costume. And the illusionistic movement is expressed by the de-sign to which the textile pattern or reflection of light is applied so that the movement is larger than the actual movement. A sense of direction expressed on the cos-tume by the actual movement creates a light rhythm and adds interest to the costume. This reflects a part of psychology of modern men who are not accustomed to the statics. In the rapidly changing society of information our modern men seek after movement even in the statics. It is also true in the clothing and they seem to get a psychological rest through the immediated visual change as shown in fashion design. The simple and cheerful rhythm expressed by the illusionistic movement on the costume is attempted in order to overcome the static tediousness caused by simple design. These elements of movement cause the en-largement of visible range and create another enlarged shape other than the real one, so that they come to remove the dullness and monot-ony in costume design and provoke interest in costume, as if kinetic art reveals the various aspects that transcend the closed area of fine art upon the motif of 'movement'. finally, as this paper deals with the ex-pression of movement as shown in the costume design which prevailed after 1988, it is desir-able hereafter to study more about the fashion since 1950 when kinetic art began in earnest, along with the comparative study on the ex-pression of movement in our Korean designer's and foreign designer's works.

The purpose of this study was intended to analyze artistic formativeness represented in the modern fashion design materials. Nowadays the modern fashion design materials is characterized by variety. The fashion materials the most important of fashion is called a softwear in textile industry and emerged as a new field. Fashion design also escaped from the tra-ditional restraint and extended to pursue lib-eral clothes and the designer's creative inten-tion has resulted in conceptual and conven-tional alteration as a new mode of plastic ex-preseeion. As a results of analysis of the formative fea-ture of Art style represented in the modern fashion design materials. First Surrealism had been searching for a new way of confronting a social and rtistic environment that was stifling and repugnant to them. Accordingly the wide applicaytion of the various object due to the thought of Sur-realism through the modern fashion materials brought the diversification and individua-lization of the modern fashion design. Second Pop Art that is made modern mech-anic culture and commercialism brought the great transformation in the history of Art out of the existing style and the sense of ex-pression. And the plastic characteristics of Pop Art that has a gravity as modern fashion materials on a them of the elements of popular consumer's society. That is the common and cheap objects were introduced into fashion materials itself or pat-tern. Third Minimalism is a trend in art att-empting to seek essence of the object by presenting simple and disciplined expressions by minimal formative means. The features of external form are simplicity clarity unrelated composition and symmetrical structure. Mini-malism was a quest for basic elements repre-senting the fundamental esthetic values of art. The minimal expression in modern fashion materials mean fabrics with simple surface and is contained using simple geometric pattern or utilizing textiles without any patterns. Fourth Eroticism is a kind of psychological revolution in the development of human civilization and is deeply rooted in the cultural tradition of myth religion customs and art. So Eroticism must be distinguished from a mere animal reproduction. These erotic char-acteristics were holded the meanings of sexu-ality through the modern fashion materials. Especially it was expressed the sexual part of body was nakedly showed through trans-parent materials or semitransparent like metalic and opaque materials. Recently the various kinds of new materials such as paper vinyle plastic metal as well as human body were applied to new fashion de-sign. First of all the new materials will give modern fashion designers stimuli and inspi-ration. It can also express values of moderners to despise materialism and uniformed modern society and to recover humanity and self-actualization.

Nanofiltration (NF) is a recently introduced term in membrane separation. In 1988, Eriksson was one of the first authors using the word 'nanofiltration' explicitly. Some years before, FilmTech started to use this term for their NF50 membrane which was supposed to be a very loose reverse osmosis membrane or a very tight ultrafiltration membrane. Since then, this term has been introduced to indicate a specific boundary of membrane technology in between ultrafiltration and reverse osmosis. The application fields of the NF membranes are very broad as follows: Demeneralizing water, Cleaning up contaminated groundwater, Ultrapure water production, Treatment of effleunts containing heavy metals, Offshore oil platforms, Yeast production, Pulp and paper mills, Textile production, Electroless copper plating, Cheese whey production, Cyclodextrin production, Lactose production. The earliest NF membrane was made by Cadotte et al, using piperazine and trimesoyl chloride as monomers for the formation of polyamide active layer of the composite type membrane. They coated very thin interfacially potymerized polyamide on the surface of the microporous polysulfone supports. The NF membrane exhibited low rejections for monovalent anions (chloride) and high rejections for bivalent anions (sulphate). This membrane was called NS300. Some of the earliest NF membranes, like the NF40 membrane of FilmTech, the NTR7250 of Nitto-Denko and the UTC20 and UTC60 of Toray, are formed by a comparable synthesis route as the NS300 membrane. Commercially available NF membranes nowadays are as follows: ASP35 (Advanced Membrane Technology), MPF21; MPF32 (Kiryat Weizmann), UTC20; UTC60; UTC70; UTC90 (Toray), CTA-LP; TFCS (Fluid Systems), NF45; NF70 (FilmTec), BQ01; MX07; HG01; HG19; SX01; SX10 (Osmonics), 8040-LSY-PVDI (Hydranautics), NF CA30; NF PES 10 (Hoechst), WFN0505 (Stork Friesland). The typical ones among the commercially available NF membranes are polyamide composite membrane consisting of interfacially polymerized polyamide active layer and microporous support. While showing high water fluxes and high rejections of multivalent ions and small organic molecules, these membranes have relatively low chemical stability. These membranes have low chlorine tolerance and are unstable in acid or base solution. This chemical instability is appearing to be a big obstacle for their applications. To improve the chemical stability, we have tried, in this study, to prepare chemically stable NF membranes from PVA. The ionomers and interfacially polymerized polyamide were used for the modification of'the PVA membranes. For the detail study of the active layer, homogeneous NF membranes made only from active layer materials were prepared and for the high performance, composite type NF membranes were prepared by coating the active layer materials on microporous polysulfone supports.

This paper aims to understand the changing characteristics of the Kumi region as a locality in Korea through the regional geography of the world-system approach. To illustrate the changing regional characteristics, we analyzed the economic characteristics or position of the Kumi region within the world-economy and its spatial structure with three divisions of Korean capitalist periods: the Japanese colonial period ($1910{\sim}1945$), the social chaos period ($1945{\sim}1960$), and the economic development period ($1960{\sim}$present). In the Japanese colonial and social chaos periods, as Korean society was incorporated into the peripheral zone within the world-System (world-economy), Kumi also was made into a peripheral agricultural area. As a result, the Kumi region shaped the rural spatial structure without an urban center or regional dominant center. In the development period, influenced by the manufacturing-centered economic policy which boosted Korea as a semi-periphery within world-economy, Kumi also was developed into an industrial region(or semi-periphery) with the establishment of the Kumi electronic and textile industrial complex. This industrialization transformed the rural spatial structure of Kumi into a core (urban center)-periphery (rural area) structure. As we identified above, the regional geography of the world-system approach turned out to be a useful methodology to study a locality or internal region. Therefore we should make efforts to study such regions through the regional geography of the world-system approach.

Recently medical and entertainment applications using conducting textile are suggested, but the data of conducting threads are not characterized, classified and verified. Only the data sheet published by manufacturing companies is available. Thus we need to verify the performances of the threading threads in communication. And we need a guideline if the existing communication protocols can be used for the conducting threads communication or the new specific communication protocols have to be developed for the communication. This paper classifies the characteristics of conducting threads made by domestic and overseas companies. Based on the criteria we classified conducting threads into three classes: class A, class B and class C. Further we carried out experiments to verify the adaptability of existing simple serial communication protocols such as RS232. Six different conducting threads are used in experiments and the length of each thread was 0.5m, 1m, 2m and 3m. The data transmission rate and error rate are collected and analyzed. RS485 is very prone to error due to static electricity from human and environment. So it may not be appropriate as long-distance communication protocol up to 12km which is possible in theory. RS232 shows stable and error-less data transmission ability even though every conducting thread didn’t show transmission capability over RS232. USB protocol shows high data rate transmission but the distance cannot be exceeded over 2m. Additionally, USB requires stable power supply. But if the power is supplied through conducting thread, its function is not.

In the part 1, relations were found between fundmental mechanical properties and primary hand values, performance of Korean women's summer fabrics. In this paper, in order to investigate the hand values and mechanical properties such as tensile, shearing, bending, compression, surface and thickness & weight of the women's fall & winter fabrics were measured by KES-F system. Sorts of 90 commercial fabrics for women's fall & winter clothes were classfied into 39 silk and 51 polyester fabrics according to meterials. The experimental results were analysed statistically to relate the hand values and the mechanical properties and concerning to formation of weared clothes and transformation behavior were investigated. Furthermore, there mechanical properties as well as their hand values were discussed in comparison with those values for kimono fabrics. The main results are summarized as follows; 1. The shape of silk fabrics in formation for weared clothes show a box-shaped silhouette. Polyester fabrics has a easy to shape-less and make a silhouette which goes along with the body. 2. Silk fabrics for Korean women's fall & winter clothes have ${\pm}1\sigma$ range of bending, shearing, surface properties and thickness as compared with kimono fabrics. 3. A wrinkle recovery and drapability of silk fabrics for Korean women's fall & winter clothes are inferior to kimono fabrics. On the other hand, the fabrics for Korean women's fall & winter clothes have conical-shaped silhouette based on higher bending rigidity. 4. Except for flexibility with soft feeling, a primary factor of mechanical properties contributes to the hand values of fabrics for Korean women's fall & winter clothes having no concern with materials were same as the women's summer fabrics. 5. As for the hand values of fabrics for Korean folk clothes, stiffness, anti-drape stiffness are larger than those of kimono fabric and stiffness, anti-drape stiffness, crispness of fabrics for Korean women's fall & winter clothes have smaller values as compared with Korean women's summer fabrics.

Red pine (Pinus densiflora) is widely used traditional medicine, pharmacological and nutritional values from which the phytochemical compounds are derived. The present study was aimed to examine the antibacterial effects in the absence and presence of a immature red pine cone extract against 13 microorganisms. The components in the aqueous extract from immature red pine cone were identified by GC-MS. About 1.4% of total polyphenolic compound was measured in aqueous extract collected from immature red pine cone. Also, the high concentration of ${\beta}$-phellenandrene, ${\alpha}$-pinene, limonene, bornyl acetate and aldehyde was detected in total ion chromatograms. Of total 13 microorganisms, 4 microorganisms including Pseudomonas aeruginosa, Vibrio cholera, Listeria monocytogenes, Klebsiella pneumonia were effectively killed by aqueous extract of immature red pine cone. The highest anti-bacterial effect was detected in P. aeruginosa, followed by V. cholera, L. monocytogenes and K. pneumonia. In case of P. aeruginosa, the largest diameter of inhibition zone was maintained to 1/2 solution treated cells and slightly decreased at 1/4 and 1/8 solution treated cells. Also, in test used V. cholera and L. monocytogenes, the inhibition zone was strongly formed in only 1 and 1/2 solution treated cells, while K. pneumonia showed the very small diameter of inhibition zone in all concentrations. Therefore, these results suggested that the aqueous extracts of immature red pine cone should be considered as a new and potentially important anti-bacterial substrate to effectively prevent the microbial infection and penetration.

This paper analyzes the asymmetric pass-through effects of crude oil price changes on export prices in Korea's manufacturing sector using a nonlinear autoregressive distributed lag (NARDL) model. These pass-through effects are important for Korean companies that are highly dependent on exports. Because the effects differ by industry, eight sectors of the manufacturing industry were examined. The model is effective for separately testing the long-term and short-term differences between the export-price pass-through effects when crude oil prices increase and decrease. The estimation results show that there is positive pass-through to export prices as crude oil prices change, and there are asymmetric effects in some manufacturing sectors. Short-term asymmetries were detected in the export prices of five sectors that include general machinery and transport equipment, and significant long-term asymmetries were found for petroleum and coal products and for textile and leather products. The long-term export price of oil and coal products rose by 0.992% with a 1% increase in the oil price and fell by 0.977% with 1% decrease. Therefore, corporate strategies and government export policies should be established in accordance with these asymmetric pass-through effects.

The gold textile is Korean traditional weaving technique using the gold thread since 5th century. The making technique of gold thread was written in various references, but it is severed because the gold thread weaving equipment and sumptuous moods were forbidden in the early 18th century. There are some studies of traditional gold thread which are mainly about conservation treatment of cleaning and strength. To restore traditional gold thread, investigation of material and manufacturing technique is vitally required. The gold threads are composed of gold leaf, adhesive and base sheet. Gold leaf and base sheet are available for investigation because they are exposed to the surface, whereas adhesive is not easy to investigate because it is not exposed to the surface. In this study, samples are made of pure and impure gold, animal glue and lacquer, and various types of Hanji based on domestic and foreign references to compare materials for gold threads. As a result of morphological character and stability evaluation, the optimum materials for the restoration of gold threads are pure gold, animal glue and Dochimji(smoothing paper by beating). This study is expected to be basic data for manufacturing gold threads techniques and modernization of traditional gold threads hereafter research.

This paper studied the effects of the content and the orientation of the disk shape fillers on the modulus of PP composites. The experimental results were compared with the theoretical calculations which included the three dimensional ellipsoids and analyzed by two aspect ratios, ${\rho}_{\alpha}=a_1/a_3$and ${\rho}_{\beta}=a_1/a_2$proposed by Lee and his researchers. Mica and talc were used as disk shape fillers in the composites. The shapes of mica and talc were observed by SEM and aspect ratios were statistically calculated. For the case of mica, the average aspect ratios were ${\rho}_{\alpha}=13.5$ and ${\rho}_{\beta}=1.8$, and for the case of talc, they were ${\rho}_{\alpha}=3.8$ and ${\rho}_{\beta}=1.4$. Also, the effects of two aspect ratios and the content of filler on the mechanical properties were studied: For 30 wt% of mica, $E_{11}$ increased up to about 2.7 times, and for the other case of talc, $E_{11}$ increased up to about 2.3 times, respectively.
