The purpose of this study is to investigate types and formative characteristics of 'Seon' represented of costume in Water-moon Avalokitesvara of the late Koryo Dynasty. The results were as follows; 'Seon' has two main types, Standard and Decoration types. In the former type, Seon has not any decoration. While, in the latter, Seon is added with decorations. Here, Seon of decoration type can be reclassified into two types, same color and pattern and different color and pattern. Seon most appeared in the Water-moon Avalokitesvara had the type of Decoration, especially different color and pattern. Patterns used for Seon were complex in its composition type and filling in its arrangement style. Seon was mainly used to Guneui(裙衣) and Samkaksika(僧脚崎). For the color combination of Seon, the combination of similar colors was most often used and that of same color was somewhat frequently done. Regarding costumes aesthetic characteristics in accordance with the type of Seon, those costumes appeared natural and elegant when their Seon was Standard in type, natural and brilliant when same color and pattern in type and artificial and brilliant when different color and pattern.

Compared with synthetic dyes, natural dyes have inferior colorfastness as a result of the exposure of the material to any environment that may be encountered during the processing, testing, storage, display or use of the dyed materials. Especially, colors on fabrics fade excessively after washing. Therefore, it is problem to infer the historic textiles with natural-dyed fabrics. The object of this study is to analyse the factors affected to colorfastness and color change during washing. In experimental, fifteen natural dyes were dyed by the Korean traditional dyeing methods onto natural fiber fabrics: cotton, silk, ramie, and flex. Total 49 dyed fabrics in combination with dyes and fibers were used for the specimen. The Launder-Ometer was used for evaluating the effects of exposure to repetitive washing from 1 to 20 washing cycles (KS K 0430). Color difference(ΔE) in the CIEL＊A＊B＊ color-order system were determined by spectrophotometer at 100 bserver. Washing caused significant changes in the color of natural-dyed fabrics. The degree and nature of color changes on the fabrics were dependent on the combination of fiber and the dye type used. The groups of violet(Lithospermum erythrorhizon Sieb.et Zucc) and black color(Ailanthus altissima Swingle, Phus trichocarpa Miq) yielded excellent colorfastness to repetitive washing. The group of indigo blue color(Polygonum tinctorium Lour.) was also very resistant to color change in washing except silk. Whereas the dye groups of Red, Yellow, Orange, Brown colors indicated greatest changes in color, particularly Carthamus tinctorius L.

The significant role of colors in fashion design is not enough to emphasize in terms of one of the important design elements and its influences on the behaviors of the people. The purpose of this research is to examine the traditional Chinese colors and its ways of color combinations to appreciate the Chinese culture and its people. The Chinese traditional costume of Ching Dynasty were investigated through historic records, historic nobles, costume accessories and so on. The results of the study were summarized as follows： (1) The Blue was the most favoured color for clothing among men and women during Ching dynasty and various blues in terms of hue, value and intensities were used. (2) The bright Yellow which had been a symbol of Emperor were prohibited being used among people. Though, the late period of Dynasty, the regulation became not to strict and various shades of yellow families were adapted among People. (3) The Red which had been preferred during Ming Dynasty were constantly favoured for the formal wears of auspicious events such as weddings. (4) Dark color groups were loved for the clothing which were used as a ground colors against the flamboyant patterns revealing strong visual effects through value contrast or primary color combinations. (5) The White had a symbol of mourning and there were some intentions to adopt pale color groups such as mint, jade, gray, moon whit,. silver white to make up for white. (6) Contrast color combinations were one of the basic ways of color combination in Chinese traditional costume. Therefore Chinese color combinations has a strong visual effect and easy to draw attention of people by the contrast of the hue, value or intensity of color. (7) Multi-color combinations were another characteristics of Chinese costume in the formal wears which bears many surface designs. The surface decorated with full of motifs, were appreciated by the people expressing their longings and hopes through the auspicious meanings of patterns and striking visual effects of color combinations.

The analysis of the data was managed by computer; frequency, percentage, mean, standard deviation, t-test, and ANOVA. The results of the study are as follows; 1. The significant difference in clothing behavior according to intelligence was verified in four: modesty, comfort, management, and psychological dependence. 2. The significant difference in clothing behavior according to socio-economic status was verified in all of eight clothing behavior variables. 3. There was no significant difference according to physical constitution in all clothing behavior variables. 4. There was no significant difference in the preference styles of clothing according to intelligence, but high intelligence group took more interest in detailed factors; design, style, total combination, color, print, and comfort. 5. The upper and middle class preferred slacks and lower class preferred skirts. The upper class took interest in design-style, total combination, and comfort, the middle class in total combination. and comfort, and the lower class in total combination. 6. Thin group preferred skirt, the average group preferred slacks, fatty group preferred slacks and shirts-blouse. Thin group took interest in design-style, and color-print, the average group in total combination, and fatty group in total combination, color-print, and design-style.

This study is fundamental research on how to be able to scientifically quantify and reproduce a natural dyeing procedure. By dyeing silk fabrics, the establishment of a reproducible dyeing method was sought. Juglans mandshurica has been known as one of the most widely used black vegetable dyes. Repetition conditions and combination dyeing were performed with Juglans mandshurica cortex, gallnut, clove, and Eclipta prostrata L. extracts to express a deep black color. Juglans mandshurica cortex, gallnut, clove, and Eclipta prostrata L. extracts were suitable for black coloration and showed a darker black color when combined with iron mordant. Specifically, Juglans mandshurica cortex and clove can be used for deep black coloring. Color fastness when washed or dry cleaned was found to be strong with a grade of 4-5 and fastness to light was rated at a 3-4. The grade of color change when exposed to rubbing and perspiration was good at a 4-5. In regards to functional property aspects, it showed excellent results with a 99% deodorization rate at 120 minutes of dyeing time, 97.1% UV protection rate, and 85.9% and 62.3% bacterial reduction against Staphylococcus aureus and Streptococcus pneumoniae, respectively. Therefore, it is considered that the extract from the Juglans mandshurica cortex is of great value as an eco-friendly, natural dyestuff.

This study was performed to examine the effects of infrared (IR)/heated-air combination drying on some quality attributes of Korean white ginsengs. Ginseng roots were dried in a dryer where both the far infrared ray and heated-air are available as drying energy sources. Diametral shrinkage, external color, total saponin content, and ginsenosides and free sugar composition of the IR/heated-air combination dried ginsengs were measured and compared with those of commercial white ginseng products. The external color became lower in lightness and higher in saturation as the IR radiating plate temperature increased. IR/heated-air combination dried white ginsengs at IR plate temperature of 100$^{\circ}C$ was comparable to the commercial white ginseng products in color characteristics. Diametral shrinkage ratios ranged from 20 to 36% and appeared to be independent on the different drying methods. No definite evidence could be found whether the IR/heated-air combination drying and the conventional. hot-air drying practice resulted in white ginsengs having different ginsenoside contents and compositions. No conclusion could be made on whether the various drying treatments used in the study had effects on the free sugar contents and compositions of white ginsengs.
