환자복은 생리적 쾌적성이 저하되고, 위생 문제가 심각하게 대두되지만 기존의 소재로는 쾌적성, 위생성 등 환자복으로서의 요구 성능을 충족하기 어려우므로 실제 환자복 소재로 사용되는 면직물의 성능을 개선하고, 가공 효과와 경제적인 측면을 고려한 기능성 가공을 함으로써 위생적 특성의 변화를 도모하였다. 가공제로는 천연고분자이며 생체적합성이 우수한 키토산과 아울러 키토산의 단점을 보완하면서 부가적인 성능을 기대할 수 있는 은나노 용액을 혼합비율에 따라 처리하여 항균성, 소취성, 수분 특성 등의 위생적 특성의 변화를 검토하였다. 가공처리 직물의 항균성은 키토산/은나노 혼합용액의 처리농도가 200ppm 이상에서 아주 우수한 항균성을 보였으며, 황색포도상구균은 10회 세탁 후에도 항균성이 감소되지 않았으나 폐렴간균에 대한 세탁내구성은 크게 저하되었다. 또한 키토산의 비율이 높을수록 아주 우수한 소취성을 보였으며 공기투과도, 투습도, 수분율은 은나노의 혼합비가 커질수록 다소 감소하였는데 이는 은나노 입자의 부착 때문으로 생각되었다.

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 study is about women's veils from Chosen period housed in various museums and see how they reflect the escalating inequality between the two sexes based on Confucianism and its social ramifications including the strict rules that kept women from freely communicating or staying in same quarters with men from tender age. I first visited various museums to see what kind of veils they had in their collections and then looked at reproductions, museum catalogues, and other studies to get a better understanding of the designs, colors, and fabrics of the veils in each collection and came to following conclusions:. 1. I looked at 26 veils of 7 different sues both in person and in museum catalogues, and they included a Neouls,3 Myunsas, l2Jahngots,4 Chuneuis,1 Sahkgat 3Junmos, and 1 Garima. Various documents attest to the existence of one more style of veil,1. e. skirt-shaped veil, but there was no specimen of the type. 2. Museums had various types of veils for women, but most of them dated from late Chosun period. 3. Female veils in Chosun period had dearly-defined characteristics depending on their wearers. Each type had its own fabric color, and form, so one could tell the status of the wearer just by looking at it 4. The veils that I found at museums around the country had following characteristics: . Neoul was worn by high-class women and it covered up the face better than other types of veils. Myunsa was also caned Myunsapo, and it featured brilliant gold foils to mark the salted status of the wearer. Jahngot was originally a robe for both sexes but it turned into a type of veil for low-class females in late am period and there were more Jangots in museum collections than my other type of veils. Chuneui has various styles and it has a cotton lining so low-class women wore it to both cover the face and to stay worn Sahkgat was worn by low-class women for its convenience. Junmo was elaborately decorated and showy, and it was worn by courtesans. Garima was worn by courtesans or professional women in medicine, and unlike other type of veils, it showed the face of the wearer.

Lyocell is a not only environmentally-friendly but also very advantageous fiber. When Lyocell is soaked in water, its wet tenacity does not decrease and elongation and moisture regain of it are better than cotton. However, one drawback of lyocell is its fibrillation. The fibrills of lyocell were generated during wet process such as scouring and dyeing deteriorates the dyeing color depth and the appearance of fabric. The purpose of this study was to decrease the fibrillation tendency of lyocell fabric using crosslinking agent, epichlorohydrine(ECH). The effects of NaOH scouring and ECH crosslinking were observed. The different types of ECH addition methods to lyocell and the various concentrations of ECH in crosslinking reaction onto dyeing characteristic and fibriallation were investigated. Weight loss and whiteness index of crosslinked lyocell by ECH were examined. K/S values of ECH treated lyocell fabrics dyed with reactive dye were measured and SEM images of untreated and treated lyocells were observed extensively to define the fibrillation tendency. The results were as follows ; 1) ECH treatment showed the effect of weight loss and scouring because ECH crosslinking reaction was conducted in alkaline condition. 2) The increase in ECH concentration from 5 to 30% does not affected K/S value changes. 3) ECH crosslinking can effectively prevent the fibrillation tendency of lyocell.

African marigold is a common plant easily available in many flower beds. It has been reported as a practical and prospective resource of dyes since the dyes can be extracted from their bodies as well as petals. In this research, cotton and ramie fabrics which are made from natural cellulose were dyed using the extract of the African Marigold which is a variety of marigold. Dyeing tests were carried out under different pH of the dye solution and mordants. Dyeability was evaluated by examining and measuring surface color, K/S value, and the changes in the maximum absorption wavelength. The probability of improving dyeability was investigated by pre-mordanting with pre-treated chitosan. For the dyeing with marigold extract, the color tone did not differ by pre-mordanting and non-mordanting. Reaction with post-mordanting was excellent, which was colored in various yellow series. The best dyeability was achieved in dye solution of pH 6.5-7.0 which is not conditioned. The largest K/S value and color difference were obtained in tin mordanting. The dye uptake was greatly increased in chitosan pre-treated mordanting compared with the post-mordanting without chitosan pre-treatment. Due to its high heat resistance, African Marigold extract is easy for dye extraction and dyeing, and its dyeability is excellent for natural cellulose fibers. Also, colorfastness was proved to be practically usable.

This study is aimed to produce natural dyeing garments, which contain the sentiments and color sense of Koreans, by using various household supplies, with a view to increase the values added and utilization of natural dyeing. The dyes mainly used for this study are multi-colored ones which are durable after dyeing and can represent various colors. They include Lithodpermum officinale, Caesalpinia sappan, Rubia Cordifolia, Pellodendron Bak, Curcuma Longa L., fallen Ginkgo Biloba, Artemisia Princeps, and Quereus acutissima carr shell. Considering water pollution and other things, aluminum acetate and ferrous chloride were used as mordants. Cheap and practical materials such as cotton cloth and those with traditional patterns and elegance such as silk and ramie fabrics were used to produce baby goods, household supplies, clothes, and accessories. The produced supplies closely contact with our body, so they may have a great effect on human body. The household supplies produced include rug, bedclothes, room bedclothes, curtain, bedding set, cushion, and sunlight blind, in consideration of the functionality or medical actions of the goods which are closely related to the human skin. The infant supplies produced include longcloth for newborn baby, bedding set, gauze handkerchief, and doll. The clothes include night gown, shirt, bath gown, and Korean traditional clothes. The accessories include tablecloth, cup pad, bag, wrapping cloth, mouse and keyboard cushion, and scarf. Nowadays, consumers prefer environment-friendly naturally dyed garments and products. In order to control the naturally dyed garments and products which are traded in the domestic market, it is urgent to introduce such ecological marks as 'Toxproof' and 'Ecoproof.' Currently, many ordinary persons, who are not experts, have interest and participate in natural dyeing, but they simply produce naturally dyed garments, not artistic works or everyday supplies. The present author expects this study will contribute to the production of household goods by such persons. The author also hopes that they will develop and commercialize such designs as suit to modern tastes and senses based on the unique cultural assets of Koreans, so that Korean naturally dyed products may be recognized as reliable commodities equipped with international competitiveness.

The main purpose of this research was to provide an example of a scientific and systematic approach to designing nurses' uniforms. Uniforms for the staff nurses and head nurses at Korea University Medical Centers were designed through the following four steps: research and analyses, design direction establishment, design presentation, and final decision. For the research and analyses, a focused group interview with 14 head nurses were conducted before the actual questionnaires were formed and distributed to 200 nurses at the medical centers. The data collected from 182 among 200 subjects were able to be used for the statistical analyses. As a result, the majority of nurses were not satisfied with the present nurse uniforms. They preferred pants to skirts, and straight pants to tapered pants. Blouses or jackets that slightly cover hips with sleeves reaching above the wrists were also preferred. Many respondents wanted uniforms that were practical and easy to manage. The ideal image of nursing uniforms were feminine, lively, active, light, cool, simple, and modern. According to the research and analyses result, design directions were established and uniform designs were presented to head nurses. Uniforms were designed based on symbols of Korea University and Korea University Medical Centers. Colors including white, pink, and grey were selected to represent the ideal image of nursing uniforms designated by the respondents. Fabrics including polyester(95%) and spandex(5%) blends, polyester(48%), rayon(48%), and spandex(4%) blends, and cotton(100%) were used for making garment samples. Final designs were decided by selecting and modifying the designs presented to the head nurses.
