The purpose of this study was to investigate the dyeing properties and anti-microbial ability of silk and wool fabrics dyed with Terminalia chebula Retzius(TCR) extract using two extraction solvent, hot water and methanol. Dyeing properties of fabrics were studied by investigating the characteristics of colorant, changes in dye uptake under different dyeing conditions, and by investigating color change when mordants were applied. Also, color fastness, and antimicrobial activity of dyed fabrics were estimated. Regardless of extraction solvent type, colorant showed maximum absorption wavelength at 280 nm and 578 nm, which implied that tannin was the major pigment component of TCR. Also, through FT-IR spectrum result, it was confirmed that tannin of TCR methanol extract was hydrolysable tannin. But for the hot water extract, it was only assumed that its tannin was condenced tannin. Fabric dyed with hot water solvent extract showed higher dye uptake than fabric dyed with methanol solvent extract, dye uptake increasing by higher concentration of the dye, longer dyeing time and higher dyeing temperature. And the absorption curve between TCR extract and protein fiber was shaped in the form of Langmuir adsorption isotherm. Fabric dyed without mordant was yellow in color, and when dyed with mordant, fabric showed various colors depending on mordant types except Sn. Color fastness to washing was generally fine and color fastness to light was moderate. But color fastness to rubbing and dry cleaning was outstanding. Lastly, dyed fabrics showed very good antimicrobial activity of 99.9% against Staphylococcus aureus and Kiebsiella pneumoniae.

This study prepared 5 retroreflective fabrics of glass beads and colors of silver, gold and purple in order to characterize morphologies, luminance and illuminance properties. Retroreflective fabrics were prepared according to division and area by Samp.1 (Division 2, area $80cm^2$), Samp.2 (Division 2, area $60cm^2$), Samp.3(Division 3, area $60cm^2$), Samp.4 (Division 5, area $50cm^2$), and Samp.5 (Division 1, area $100cm^2$). The results of the morphologies indicate that the back side of retroreflective fabrics was the 3M-Sv, RF-Sv. The RF-Gd of the fabrics were woven fabrics and the SRF-Sv, SRF-Pp was knitting. The largest glass bead size was 3M-Sv and the smallest was SRF-Pp. RF-Sv was the thinnest and SRF-Sv, SRF-Pp were the thickest. The results of luminance properties indicated a tendency to decrease slightly as the number of divisions and area increased, except for Samp.2 to Samp.3. The result of illuminance properties tend to increase as the number of LED becomes greater than the number of divisions in the same area; in addition, the higher the luminance as a whole increases. The results show that it is preferable to use a silver-colored RF-Sv which has the highest luminance and physical properties when a retroreflective fabric is applied to clothes.

The purpose of this study was to analyze the factorial structure of the criteria on clothing selection. Data were obtained from 219 housewives in Seoul. 95 likert type questions were selected from the existing questionnaires and from the open end questions. The items were analyzed for discriminating power, followed by the factor analysis. 57 items were subjected to the principal component analysis with orthogonal rotation after extraction of 5 major factors. 47 items were found to be significantly loaded to at least one of the five factors. The factors had the following characteristics: Factor I. The persons scoring high on this factor would invest time and energy in their clothes to achieve their image and individuality. They were interested in clothes, appearance and fashion. Factor II. The persons scoring high on this factor were more concerned about the practicality of clothing, such as ease-of-care, comfort, texture and quality of fabric. They would not select the clothes which soiled easily and would not perform as expected. Factor III. High scores on this factor were associated with the eagerness to get the cloth-ing value for the money. They would make a long plan to buy an expensive clothing and choose a unique clothing regardless of fashion. Factor IV. A high score on this factor was suggestive of modesty. They were willing to buy inconspicuous clothes, such as dark or muted colors, small prints and conservative styles. Factor V. High scores on this factor were characterized by the desire for conformity and approval of their friends. This result may be used to develop an instrument to measure the criteria on clothing selection of consumer.

The purpose of this study is to help develop high quality brassieres with functionality and comfort, fitting adolescents' physical features during their growth period. This study conducts a comparative analysis of juvenile brassiere and adult brassiere to identify the problems of brassieres in the market. The raw data for this study was processed by SPSS 10.1. The results of this study are summarized as follows: 1. The results of this survey show that the girls' satisfaction of their breasts has correlations between breast protrusion degree and volume. The girls think that if they have protrusive breasts their breast volume is big, and their breast satisfaction level shows high. 2. The results show that the objective of brassiere wearing is to prevent breasts sag and rupture, make good breast shape, balance their entire body shape, and make beautiful outer garment line. Brassiere functions are to prevent jiggle of breasts, make a good body line, and cover the nipples. For the grader school students, they are wearing brassiere to make a good balanced body and as their breasts developed, they are wearing brassiere for beautiful body shape not just to cover up their breasts. 3. In regard to brassiere cup size recognition, as students have higher grade at school, they have better recognition abouxt their cup size. As they are better aware of their cup size, they have better satisfaction with their cup size. Therefore, choosing the right size of brassiere for their bust is very important. 4. Girl students' brassiere preference shows that 317 students (56.9%) prefer white for brassiere colors, following pink and flesh color. Their most preferred brassiere material is cotton (354 people, 63.6%) because cotton is not sensitive even for weak skin. For brassiere style, 273 students (49%) prefer round style, following spots and mold. Their most preferred brassiere style is stake. In addition, brassiere should not press their breasts because their breasts are developing during puberty period.

The costumes (including mask) of the first World Master series of The National Changguk Company of Korea, Achim Freyer's 'Mr. Rabbit & Dragon king' is directly designed by Achim Freyer who was in charge of direction and stage design. The new form called Pansori opera is proposed for modernization of Korean traditional opera, it maintained the original form of music yet introduced play form of opera. The costumes and stage also promoted modernistic transformation while maintaining the original Korean form. The overall concept of 'Mr. Rabbit & Dragon king' costumes emphasizes comical effect by abstractness like childlike scribble. It expressed characteristic of characters diversely through exaggeration and expansion while maintaining original form of Hanbok, used surface of costumes as a drawing board, and created flat and geometrically transformed silhouette. The complicated characters was caricatured like everyone is doing mask play by using masks, and it still maintained sophisticated oriental color with modern application of five cardinal colors. It may seems it just mixed our traditional elements like a hint of humor, however, it could be known that it introduced various techniques in it to deliver new subject while maintaining the original form of 'Mr. Rabbit & Dragon king'. From this study, open mind for our tradition and need for diverse attempt could be rediscovered and could also see the possibility to contribute on creating a Nation Brand of traditional performing art.

The function of the school uniform is to represent the role of a student and also to restrict the scope of action for the student. Many students wear school uniforms for the most of their daily life. So the school uniform is very important for students during the school days. The purpose of this study was to suggest the fundamental information for the development of the school uniform design based on actual wearing conditions and preferred designs. Photos of school uniforms of 61 girls' high schools in Seoul were analyzed. Surveys of actual wearing conditions and preferred designs were investigated. The major conclusions of the study were as the following: 1. Most of the high school girls wore the uniform jackets that had tailored collars, were single breasted, slightly fitted, and that have a medium length between the waistline and hipline. Many students wore skirts with various pleats and knee length. Many school uniforms were navy blue and grey. 2. Many students bought ready-to-wear school uniforms from agencies with their parents. When they bought the school uniforms, they tried it on and confirmed the sizes on their own. However, since they didn't know the size systems, and they had to repair the size and design of the school uniforms. Students felt uncomfortable with how the shoulders and sleeves fit. 3. Uniform Jackets with tailored collars, single breasted, slightly fitted, and a short waistline length were preferred. Pleats skirts with knee length or upper-knee length were preferred. Navy blue and grey colors, and elastic fabrics were preferred. 4. When comparing the actual wearing conditions and preferred designs of school uniforms, there were a few differences in styles, but overall, students preferred shorter lengths of jackets and skirts. It is considered to reflect the fashion trends and the students' pursuit for beauty.

After observing various changed colors by some dyeing conditions in case of the Indio and Indigo Pulberata Levis, we had below result. 1. Best reduction temperature for Indigo was $50^{\circ}C$, and the reduction temperature had an effect on level dyeing and dye-uptake. For the Indigo Pulberata Levis, best reduction temperature was $60^{\circ}C$, and best reduction time for Indigo was 20 minutes, for the Indigo Pulberata Levis was 30~40 minutes. 2. Both Indigo and Indigo Pulberata Levis showed high K/S without using alkali, but it was almost not possible to be dyed without reduction agent. The best amount of potassium carbonate concentration and soldium hydrosulfite concentration was $2{\sim}3g/{\ell}$ and $2g/{\ell}$ each for dyeing. 3. The best dyeing temperature for Indigo was $30^{\circ}C$ and $60^{\circ}C$ for Indigo Pulberata Levis. 4. In case of Indigo, K/S increased slightly at $5g/{\ell}$ concentration. Thus, $5g/{\ell}$ is efficient amount. However, it needed $50g/{\ell}$ to increase K/S for Indigo Pulberata Levis. It tells that we need a lot of Indigo Pulberata Levis for dyeing dark color. 5. Indigo dyed cotton looked more greener than silk. Since silk absorbs lots of red color, it looked strong red color. However, Indigo Pulberata Levis looked greenish on both cotton and silk. 6. Since the hue's range of Munsell's value was PB for both Indigo and Indigo Puberata Levis, we are able to know that red color's indirubin is contained as well as blue color's indigo.

The purpose of this study is to identify the factors that influence consumers when they purchase or rent Hanbok. We investigated the factors which affect consumers buying Hanbok, out of expectation that the rising interest in Hanbok caused by diversification of design and other various reasons would have a positive impact on purchases. Reflecting the increase of consumers renting Hanbok in the study, we also analyzed the factors that have an influence on rentals and compared the determinants of purchasing Hanbok and that of renting it. It turned out that consumers are mainly influenced by design, popular colors they prefer, and recommendation of clerks or friends. Through the comparison, we discovered that the purchasing group is more influenced by design while the renting group is more influenced by recommendation of friends and clerks. This result suggests that it would be an effective marketing strategy for shops to strengthen competitiveness by diversifing design of Hanbok, and for rental shops to do so by placing professional salesperson.

This research investigated the needs analysis on consumers of fine dust masks to effectively develop a design prototype. Data were collected through focus group interviews on 32 individuals who have used fine dust masks. As a result, there is a new demand by consumers for technology based design changes that better fit the nose and face. Consumers preferred the smell and feel of traditional Korean paper. Young adults expressed the importance of masks that can be used for protection as well as fashion. The prototype improved the drawbacks of existing models using an origami-inspired design in a variety of colors, patterns and in sizes that are customized to fit the wearer. The proposed prototype is made of Dak felt fibers and jersey materials. It is characterized by downward-facing ear bands made of polyurethane to improve the fit around the ears and chin to more effectively block incoming air. The mask is foldable and has a crease that goes along the chin to increase the amount of enclosed space against the face making it easier to breathe compared to existing mask designs.

This thesis that is written by inquiring the shoes of 1990's, is written in order to propose the method of analyzing the changes of shoes design systematically. The picture to be gathered was a content analysis low at ARS and Accessory Collegioni since though the research method took shoes to $1990{\sim}1999$. I categorized the design factors into shape, material, color, decoration. by using those category, the result of analysis of design character. In 1,990's, boots, pumps and straps were the most popular in upper, point and rounded cuban and french were the most popular in toe, leather was the most popular in materiel, suede in F/W and patent in S/S. Black was the most popular color, brown in F/W and white/beige in S/S were the second. Re-created shape that was constructed through the reconstructions of structures and shapes of shoes, shape that was expanded to other genre were appeared in character of design factor. Material image was strengthened by varying patterns of unburned calf, leopard and zebra. Recognition of shoes color was expanded by using unique colorations and abstract, fresh figure colors. Post-modem tendency was appeared like using brassiere strap instead of back strap or using round string in elegant shoes.
