The separation of indole from a model mixture comprising four kinds of nitrogen heterocyclic compounds [indole (In), quinoline (Q), iso-quinoline (iQ), quinaldine (Qu)], three kinds of bicyclic aromatic compounds [1-methylnaphthalene (1MN), 2-methylnaphthalene (2MN), dimethylnaphthalene (DMN)], biphenyl (Bp) and phenyl ether (Pe) was examined by batch cocurrent 4 stages equilibrium extraction. The model mixture used as a raw material in this work was prepared according to the components and compositions contained in coal tar fraction (the temperature ranges of fraction: $240{\sim}265^{\circ}C$). An aqueous solution of formamide was used as a solvent. Indole was recovered more than 99% through 4 stages of the equilibrium extraction. The range of selectivity of indole in reference to DMN obtained through the 5 stages equilibrium extraction was found to be 63~118. The process for separation and recovery of indole contained in coal tar was studied by using the experimental results obtained from this work and the previous work.

This study analyzes the current educational curricula in the field of Clothing and Textiles in order to develop appropriate educational methods and courses. We reviewed the curricula offered by 58 Clothing and Textiles Departments at four-year universities in Korea. We analyzed the educational content of each curriculum by dividing all of the courses offered into eight categories. The analysis was based on the information posted on the universities' Internet websites, and the analysis was performed by using descriptive statistics. The results of this study are as follows: First, the educational courses of the Clothing and Textiles Departments are composed of, 36.2% design, 20.4% production, and 14.5% textile categories. In comparison with the results of a similar study conducted in 1999, emphases on the design, distribution, and marketing categories have increased, while the emphases on the production, apparel material, basic knowledge, and consumption science categories have decreased. Second, in the case of the apparel material category, basic knowledge of materials constituted 18.5%, the largest part of the category. The average number of units offered in the area of apparel materials by the 58 Departments was 17 units per year. The curricula were found to vary by regions of the country. The universities located in the Chungcheong region offer more textile material courses, but the universities in the Capital region offer fewer textile material courses than other regions. Departments that are affiliated with universities that emphasize Art and Design have more courses on basic knowledge, dyeing and finishing, and fabric design than other universities.

This study applied the Q methodology to analyze the subjective evaluation and recognition patterns of elderly women's clothing preferences. For the type 1, knitted materials and natural materials were preferred, and pastel colors were preferred. The type 2 preferred pants that cover the body shape, look young, and have good simple activity. The type 3 was a type in which the waist was treated with a rubber band, the clothes were comfortable to wear and the loose style was preferred. The type 4 was simple and prefers a style with a raised neck and no fasteners, and a clothes that was comfortable to wear. Type 5 was a type that prefers a style that looks important and colorful and youthful in design or color. In order to develop ZIGTECHnology apparel for older women, it is necessary to develop a design that can look aesthetically beautiful while covering the body shapes such as bending of the back and bending of the waist by reflecting the preferences of the older women. It is considered that it is necessary to develop clothing that takes into consideration movement functionality without obstacles to movements in consideration of changes in behavior and movement of hands.

This study compares the strength properties of Jumchi-Hanjis dyed with 70% and 100% persimmon juice concentrations and undyed Jumchi-Hanjis. The Juumchi-Hanjis were made from Dakjis (mulberry papers), which were mixed with different ratios of fibers from paper mulberries originating in Korea and Thailand, including wood pulp from Canada. Research results showed that tensile, wet tensile, and bursting strengths of Jumchi-Hanjis dyed with 70% concentration were higher than those of undyed Jumchi-Hanjis. However, the tearing strengths of the dyed Jumchi-Hanjis were lower than those of undyed Jumchi-Hanjis. The wet tensile strengths of Jumchi-Hanjis dyed with 100% concentration were higher than those of dyed with 70% concentration. The increase and decrease of tensile, tearing, and bursting strengths depending on persimmon juice dyeing differed as per the mixing ratio of the raw materials of Jumchi-Hanjis. Dyeing with 100% persimmon juice concentration tends to be more useful than 70% to increase the tensile (MD) and wet tensile strengths of Jumchi-Hanjis containing only Korean mulberry fibers (90%) and wood pulp (10%) as raw materials. Dyeing with 100% concentration tends to be less useful than 70% to increase the tensile, tearing and bursting strengths of Jumchi-Hanjis with high proportions (90% or 60%) of mulberry fibers from Thailand.

Background and Objetive : The aim of this study was to investigate the effect of various electroacupuncture stimulation on NADPH-diaphorase in cerebral cortex, brain stem, cerebellum of spontaneously hypertensive rats. Materials and Methods : We evaluated the changes of NADPH-d-positive neurons using a histochemical method. The staining intensity of NADPH-d-positive neurons was assessed in a quantitative fashion using a microdensitometrical method based on optical density by means of an image analyzer. Results and Conculsion : The average optical density of NADPH-d-positive neurons of 100 Hz (bipolar square wave 0.2 ms duration and 100 Hz frequency) electroacupuncture treatment group significantly increased in most cortical areas comparison between the manual acupuncture and 2 Hz (bipolar square wave 0.2 ms duration and 2 Hz frequency) electroacupuncture groups. In the brain stem, the optical density of NADPH-d-positive neuron at only superficial gray layer of the superior colliculus area was same as cerebral cortex. We conclude that the morphological evidence for NADPH-d-positive neurons may be have regional change in cerebral cortex brain stem and cerebellum according to various electroacupuncture stimulations.

This study creates a method with more scientific patterns for use in designing golfwear slacks patterns that better reflect the unique characteristics of body types for elderly women aged 60 or older. This study investigates (when designing human-engineering golfwear slacks for elderly women) the body types of elderly women and design slacks patterns suitable for golf actions in order to design golfwear slacks that show excellence in function and aesthetics as well as for exercise and everyday wear conditions. The study indicated that "total crotch length" was the design element for most considerations when manufacturing golf slacks. A survey on the production of golf slacks for elderly women aged 60 or older showed that the 6 firms participating have not produced an exclusive product for women 60 years of age or older and have only manufactured an enlarged size up to 85. All 6 firms participating replied "No" two the question "Do you produce in consideration of the body types of women over 60 years of age?" Polyester-polyurethane composites were the most widely used (among golf slacks materials) as spring-autumn applications.

This study suggests a direction for design development through an analysis of the experiential rental Hanbok design in Jeonju Hanok Village. As a research method, 268 outfit photographs of tourists wearing experiential rental Hanbok for women were collected as design analysis data from Jeonju Hanok Village. Frequency analysis was then performed by dividing into form, color, material·pattern, and detail. The controversy over the design of experiential rental Hanbok revolves around how and how much tradition is reflected. This is a very important part of the design analysis and development direction. If necessary, traditionality was discussed using the Hanbok style of the Joseon Dynasty as a standard. Development directions derived from the analysis are summarized as follows. First, avoid the distorted shape of skirts. Second, develop underwear for traditional silhouettes. Third, expand traditional colorations and avoid the excessive use of accent colors. Fourth, it is necessary to develop rental Hanbok materials with decorative features. Fifth, there is a need to design flat pattern construction for rental Hanbok that reflects a standardized production method and a changed aesthetics.

This study reflects the aim of analyzing the formality and symbolism of the Chanel suit. Chanel had designed jersey and tweed cardigan suits in the 1910s and 1920s while her suits of the 1930s were crisply fitted. The suits of the 1950s and 960s while were comfortable and slightly boxy marked a significant step forword. Lagerfeld's mission at Chanel was to tranmute the basic elements of the Chanel style and make them contemporary. He has also introduced the contemporay wide shoulders and short tihht skirt In place of sensible knee-length skirts he offered hemlines that either grazed the ankles or exposed most of the thighs. Besides her very influential jersey and tweed cardigan suit Chanel continued to assert her considerable strength with materials often making her suits in very delicate feminizing fabrics. in place of the classic boxy tweed jacket Lagerfeld introduced jackets made of terrycloth denim and stretch fabric Many of Chanel's suits show a stylish sense of colour that would have made artist envious. Chanel and Lagerfeld chose variety of colours from beige and grey and black to blue green cerisen and red for her suits. They was completely in tune with the twentieth century understanding the changes in lifestyles of woman and also understanding how her clothes should cater to them Thus the Chanel suit is more a way of life than just a fashion and is synonymous with wealth and aritocracy. It is one of the most popular status-symbol styles of the 20th century.

This study is to understand the meaning, the location, and the construction of Hyeonhun (玄纁) through the records and relics of the Chosun Dynasty. Hyeonhun means farewell gifts for the dead. Hyeonhun was very personal and was considered to be essential ritual supplies. it was newly made for not only first funeral(初葬), but also the second funeral(改葬), was individually made as well as in the couple funeral(夫婦合葬). the Hyeonhun ritual was performed while dressed in a simabok(緦麻服). The ritual started with washing of the hands(盥手) and deep bowing(再拜) twice. The Hyeonhun was placed on the lid of the inner coffin among the 3 coffins in Chosun tomb's way. The Hyeon was placed on the right side and the Hun on the left side of the lid.(玄右纁左). Hyeonhun are comprised of one, two, five of ten pieces. Most of the excavated Hyeonhun were two pieces : Hyeonhunsokbaek(玄纁束帛) consist of ten pieces, of which six were Hyeons and four were Huns. The records indicated that the materials used to make Hyeonhun was silk, but the excavated relics satin and twill, single gauze in the excavated relics advanced than the records.

This work surveys the trend and dissolution characteristics in headdress that appear in Jean Paul Gaultier's collection. Along with a related literature review, a total of 903 headdress pieces shown in collections 40 times (excluding the common caps and hats) were analyzed, covering from 2001S/S to 2010 F/W of Jean Paul Gaultier's Haute Couture and Pret-a-Porter. The headdress trend indicated in his collections was divided into such subgroup forms of folklore, usage of natural things, usage of artificial things, religion, retro, scarf, variations in headgear, mask and veil, atypical type and abstract. Such an expression tendency was so unique and mixed characteristic that it was hard to define its form and structure thanks to enlargement and exaggeration, extremity in ornaments, and use of foreign materials, which led to creative dynamics. Gaultier's headdress also reflected the following characteristics: first, expression of difference indicative of time deconstruction; second, uncertainty of meanings via deconstruction; third, text interactivity via deconstruction of gender and material adopted; fourth, decentralization through dissolution of the Orient and the Occident.
