The copolymers were prepared by the emulsion copolymerization of fluoroalky lacrylate-stearylacrylate-m-isopropenyl-${\alpha},\;{\alpha}'$-dimethylbenzyl isocyanate (TMI) in order to obtain water repellent polymers. The respective copolymerization rates of the three monomers considerably depended upon the use of the nonionic emulsifier and the nonionic-cationic mixed emusifier, and the optimum conditions were obtained. The particle sizes of the copolymers were in the range of 105 to 222nm. The particle sizes of the copolymers prepared by the use of the mixed emulsifiers were smaller than those of the copolymers prepared by the use of the nonionic emulsifier. The reactions of both TMI-N-methyl acetamide and TMI-cellobiose did not take place. However, the reaction of TMI-n-butylamine occurred. The water contact angles before and after washing three times for nylon and poly(ethylene terephthalate) (PET) fabrics coated with the copolymer prepared by the use of mixed emulsifier were about $139^{\circ}\;and\;133^{\circ}$ Therefore, the copolymer showed good durable repellency for nylon and PET.

This study examined the excavated clothes of Lady Sim Cheongsong(1753~1810) in Jecheon which were excavated in 2012. Lady Sim died at the age of 57 and the excavated relics belonged to the 18th and 19th centuries. The excavated relics consisted of 9 pieces of three-kind-clothes. They showed various qualities such as Plain-Silk, Plaited-Silk, Patterned Twill, Plain Twill, Plain Satin, and Satin Damask. Through comparing them with the other excavated clothes of the 18th and 19th centuries, we can comprehend the periodical changes of the excavated Jegori and Yeomo (the hat for a dead woman). The excavated Jegori shows the difference of length and form from the other Jegori of the 18th century. The total length of the excavated Jegori ranged from 24 cm to 25 cm, which is 10 cm shorter than that of the other Jegori of the 18th century. The excavated hat for a dead woman shows the changes of the form and needlework. The form of a rectangular cover was changed into that of a round shape. In regards to the sewing composition, the way of inserting the cover into Mosin(the body of the hat for a dead woman) was replaced by that of connecting the cover into Mosin. The excavated clothes show three kinds of textile fabrics: plain silk fabrics and plaited silk, plain twill and four-leaf-patterned twill, eight-leaf-plain satin of life-lettered textile and five-leaf satin damask, and plain satin. Especially, the combination of eight-leaf satin and four-leaf twill with mixed textile is considered as a fabric of high quality. The excavated clothes of Lady Sim Cheongsong showed a periodical change which was different from the clothes of the 18th century in terms of the formal composition of Jegori and Yeomo. Regarding Women's Jegori a short length and slim and long sleeves are changed into short and tight Jegori, which signaled the specific change of Jegori aesthetics. The significance of the excavated clothes of Lady Sim Cheongsong lies in its role as the bases for understanding the couture culture of the 19th century.

Process conditions for the impregnation of polycarbosilane preceramic polymer into SiC-based composites were investigated. Two kinds of preceramic polymer (PCP) was impregnated into SiC-fiber fabrics with different solvents of n-hexane and divinylbenzene (DVB). Both microstructural observations and mechanical tests were conducted to evaluate the impregnation. The matrix phases were particulated in the case of hexane solvents. Apparent relative density of the matrix was about 78.8%. The density of matrix was increased to about 96.1-98.8% when the DVB was used; however, brittle fracture was observed during a bending test. The modulus of toughness was less than $0.74J/m^3$. The fabric impregnated with a mixed PCP-dissolved solution showed intermediate characteristics with relative high density of filling (apparent density of ~96.1%) as well as proper bending behavior. The modulus of toughness was increased to about $5.31J/m^3$. The composites developed by changing the precursor and solvent suggested the possibility of fabricating SiCf/SiC composites without a fiber to matrix interphase coating.

In this study, nine scarf designs expected to be effective for accent design for the fashion style of new senior women were suggested by reflecting purchase behavior and scarf preference after conducting surveys and an analysis by targeting 136 new senior women in order to propose scarf design-matching with the preferences of new seniors. As a result of the study on the scarf purchase features of new seniors, it was revealed that the purchase time for scarves was mainly autumn and winter, even though it is regardless of season, and in spring and summer, they seldom purchased scarves. The purchase frequency was four times a year, and what they first thought of at the time of purchase was represented in the order of color, design, and the material of the scarf. They most preferred department stores, mixed and achromatic colors, cotton and silk fabrics, natural and geometric patterns, and long scarves of a rectangular shape. In the case of the consumer attributes of scarves, it was revealed that $50^{th}$ desired more individuality-oriented, unique scarf designs than $60^{th}$, and $60^{th}$ desired scarf designs with convenient management considering others' attention compared with $50^{th}$. As concepts for scarf designs, the aspects of individuality, co-existence, and maturity were extracted by reflecting the features of new senior women, and a total of nine scarf designs were suggested by developing three sub-designs for each concept.

This paper is based on a survey of consumers 'opinions on underwears. The questions in the survey dealt with what materials were used to manufacture underwears, which underwears were worn together in combinations, and how comfortable underwears were. In addition, the respondents were asked about how many pieces of different underwears they posses. Through such research, this paper aims to provide a guide to manufacturing domestic underwears that are competitive against foreign bands. 336 women in their twenties, thirties, forties and fifties from Seoul and it's suburbs were surveyed. Statistical analysis was performed by calculating the average, frequency and standard deviation, and through one-way analysis and the Duncan test. The following are the results of the study : 1. Consumers were moderately satisfied with Korean-made underwears. In order to complete with foreign brands, products with high consumer-satisfaction levels must be produced. 2. Upper garments usually consisted of brassieres with shoulder straps and sleeveless shirts. For lower underwears, most people tended to wear panties under girdle, with garlets on top. This is most likely the resut of more people wearing slacks than skirts. 3. Consumer in their twenties had anaverage of 1.71 slips, while those in their thirties had 3.07, those in their forties and 3.25, and people in their fifties had 3.88 slips. Thus the number of slips a consumer possesses increases as age increases. for socks, people in their twenties had 7.4 pairs on average, those in their thirties had 5.5, those in their forties had 6.7, and those in their fifties had 5.3. Thus, those in their twenties possessed the most number of socks. Consumers in their twenties also had the largest proportion of socks among all the types of hosiery combined, with 47.1% of their hosiery being socks. 4. Consumers did tend to prefer cotton underwears, but according to the type of underwears, producting using mixed fabrics of cotton and synthetic fibers were also frequently worn. 5. The shape and form of underwear that consumers prefer in a ceratin time frame varies according to the latest fashion in outer wear. Therefore, planning design of underwear products by predicting the future trend of outer wear fashion is necessary.

This thesis is purported to contemplate glamour look reflected in fashion history, thereby to establish the styles of glamour expressed in fashion trends and to provide the categorical basis of fashion design. For such purposes, this thesis first provides the historical survey on the glamour look in fashion, and to conduct a case study by conducting survey of fashion photographs captured in an internet site called Firsview(www.firstview.com) during most recent ten-year period covering $pr\^{e}t-\`{a}-porter$ design products presented by ten leading Italian designers. Based upon the historical survey, there are four representative styles in glamour looks, including (1) luxury glamour, (2) hyperfeminine glamour, (3) kitsch glamour, and (4) romantic glamour. Luxury glamour looks were most often utilized by fashion designs of Valentino and Armani, which can be characterized by frequent usage of glittering details intended to emphasize the surface decoration. Hyperfeminine glamour looks were characterized by the frequent usage of black color in an effort to create fetish atmosphere or sensuality, which can be discovered from the fashion designs of Versace, Cavalli and Ferre. Kitsch glamour looks were characterized by the appropriation of details of vulgar subcultural features mixed with strong color combinations and ethnic trimmings. Versace, Cavalli and Dolce & Gabbana were the main designers of kitsch glamour looks. Finally, romantic glamour looks, which were mainly expressed by Valentine, Dolce & Gabbana and Versace, were characterized by nostalgia and luxury with light colors and materials such as lace and transparent fabrics.

The effect of surfactant mixture 9on detergency and soil redeposition in a dry-cleaning system was investigated employing Aerosol OT as an anionic surfactant and Span 80 as a nonionic surfactant. The effect of charge system on soil deposition was also investigated in order to determine the optimum condition at which soil redeposition is minimum,. Soil deposition instead of soil redeposition on cotton, polyester and wool fabrics was measured employing petroleum solvent and perchloroethylene as organic solvents. The results were as follows. 1. Surface tension or interfacial tension was not changed by the addition of any surfactant or surfactant mixtures. In petroleum solvent however interfacial tension between solrent and water decreased when surfactants were added and increased when surfactants were mixed,. 2. The maximum amount of water solubilization increased as the mole fraction of Aerosol OT increased and more water was solubilized in petroleum solvent than in perchloroethylene. 3. The detergency of cotton was greater and the soil deposition rate was lower in Span 80 solution than in Aerosol OT solution. The soil deposition on cotton fabric decreased when water was solubilized in Aersol OT solution 4. The detergency and soil deposition rate of polyester fabric did not change by the surfactant type of the addition of surfactant mixture and soil deposition rate increased bywater solubilization. 5. Soil deposition on wool fabric was very high when Arosol OT was employed in perchloroethylene and the soil deposition did not change greatly by water solubilization.

This study aims at analyzing the characteristics and the mode of deconstructionism expressed in fashion design centering on review of literatures and precedent researches. Through the review of previous studies and various articles, three major features with regard to deconstructionism were found: indeterminacy of meaning, decentralization, and inter -textuality. In fashion, the feature of indeterminacy of meaning expressed by non formula way such as unfinished, layering, obi or straight line cutting and it was divided into unstructured and unorganized factors. The feature of decentralization expressed by disorganization of sex, race, culture and humanism such as trans-gender, third world costume, sub-culture, posthumanism. Last, the feature of inter-textuality expressed by employing the fashion texts more than two simultaneously such as mixture of unmatched or unusual various clothing items, fabrics, patterns and styles. Non formality features in fahsion which divided into unstructured and unconstructed factors. The decentering of meaning means that disorganized the existing concepts of sex, race, culture and humanism features in fashion which divided into cross-gender, subculture, and post-humanism. Lastly, the feature of inter-textuality means that employed the fashion text more than two which is classified into factors of mixing mode and mixed styles. Unstructured factors were expressed by destroying the design principles such as balance, harmony and unit in fashion. Unconstructed factors were expressed by ignoring the basic costume structures and components in fashion. Cross-gender was expressed by manish and duality style in fashion and 3rd world costume was expressed by folk costume style. Anti fashion was expressed by anti aesthetics in fashion such as kitch, punk, and hippie styles. Post-human was expressed by futurism and the 4th Sex style in fashion. Mixing mode were expressed by mixture of item, and unmatched materials and pattern in fashion. Mixture of style were expressed by mixture of pastiche expression of various styles.

For the disposal of low-level radwaste from nuclear power plant need the determination of levels of radio nuclides in radwaste. These nuclides include the difficult-to-measure nuclides, so indirect methodology for the determination of the difficult-to-measure nuclides have to be developed. In this work, for the determination of $^129I(t_{1/2}=1.57{\times}10^7 years)$ in low-level radwaste from nuclear power plant is investigated. Recovery of Iodide in simulated waste($UO_2$ pellet) as a soluble and radwaste(resin, woolen fabric)as a insoluble samples are measured. After pretreatment of sample, $I_2$ are extracted from aqueous solution with $CCl_4$. Then I are extracted from $CCl_4$ with 0.1M $NaHSO_3$ aqueous solution. iodide in aqueous solution are determined by ion chromatography. The overall recovery yield is 76.7 (RSD 1.7%) for mixed-acid digestion method. Incase of woolen fabrics, overall recovery yield is 74.3 (RSD 2.2%) and recovery of iodide in resin 56.5(RSD 5.6%) for alkaline fusion method.
