The purpose of this study was to investigate the natural dyeability of silk on extract of Artemisia princeps, The experimental items were divided into the mordanting method. comonent of fabric, kind of mordant. The experimental study was done by laundering fastness, abrasion(dry/wet) fastness, perspiration(acid/alkali) fastness, light fastness test and color difference by C.C.M system. The summarized finding resulted from experiments and investigation are suggested as follows; First, in the C. C. M test on mordanting methods, color difference was significantly improved when mordants were treatmented. And the premordanting method showed the highest color difference, color was most yellow-greenish, Second, in the C.C.M test on component of fabrics, color difference of silk was higher than cotton. It is considered that silk has -$NH_2$ , -COOH, -OH than more than cotton. Third, in dyeing-fastness on mordants, laundering fastness showed that color-change was 2~3 grade, the contamination on attached fabric was 4~5 grade. perspiration fastness(acid/alkali) showed 4~5 grade nearly and those of acid was higher than alkali. abrasion fastness(dry/wet) was 4~5 grade and in Fe(3~4 grade) was lower than the other mordants. Forth, in color difference analysis on mordants, Fe(50.0) showed the highest and the order of color difference was alum(16.0), Cu(7.2), Sn(3.5), Al(3.1), Cr(2.3), The Hue was turned into yellow-greenish in alum mordant treatment, the luminocity of color was most dark in Fe(-48.9) and Cu(-7.2), chroma was the highest in alum (15.7) method.

The nursery active-wear uniform designs of Internet shopping malls are simple and similar; however, the latest children's wear trends (mostly composed of training jumpers and pants) do not reflect these qualities. Children's folklore plays (widely used in child education) have an instructive value for the emotional and intellectual development of a child. Nursery active-wear uniform designs applied to children's folklore's plays could be positive for the emotional development and specialized cultural education of children. We designed three nursery active-wear uniforms with three different design concepts (casual, semi-formal and sporty) regardless of sex. The main color of the three nursery active-wear uniforms was yellow. We used three different chroma and values of yellow through three design concepts: Design I of a nursery active-wear uniform (a training suit style with a good activity), Design II of a nursery active-wear uniform (a semi suit style), and Design III of a nursery active-wear uniform (a sportswear style that reflected a sport wear trend). We expressed children's folklore plays in the pattern of a nursery active-wear uniform. The pattern was characterized as a pair of bears flying kites. This pattern was utilized in three nursery active-wear uniforms with the logo and name of the nursery. We modified the designs of active-wear nursery uniforms based on an evaluation of 33 special panels. We made three nursery active-wear uniforms for five-year olds.

This Study is about the color images oi clothes in the early 20th century in the Eastern and Western culture and the recreation of this color images through modern costume design in film. The aim of this study is to show how early 20th century color has born reinterpreted through present film costumes and how different cultural perspectives can influence color images. For the purposes of this study, 30 pictures of clothing, representative of the early 20th century, as well as films which have been internationally recognized for their costume design and strong cultural identity('Farewell M) 'Concubine', 'Raise the Red Lantern', 'Chicago' and 'The English Patient') were chosen and analyzed. The color image of these photographs and scenes from the movies were divided by Pantone Solid Chips and categorized by color groups such as red, orange, yellow, green, blue, violet, neutral and metallic. The analysis results of the color images in the early 20th century showed that the red group was used a lot in both cultures and the orange group was more often used in the West. In regards to the yellow group, goldish yellow were commonly used in the West but pale yellow was preferred in the East. The green group more used In the West but the blue group appears more in the East. Also, there were differences in color combination, texture and technique which demonstrates different cultural color recognition and association. In the case of film color image, present color image was added to past color image. In the West, color was used as a tool for visualizing the state of characters' mind and the mood of movies' story but in the East color image was intended to make the character stand out by changing the value and chroma. By comparing the color image of clothes from the early 20th century and color image from film in the West and the East, it is possible to analyze the cultural symbolic image of color. This study is one of first trials to analyze the cultural differences in rotor images and their symbolic meaning. Thus, further studies should persue to find out the influence of culture on the rotor image in terms of specific quantity and quality.

This study investigated the colors of the costumes in the film 'The Handmaiden'. The author categorized and examined the hue and tone of the main character's costume as well as provided an adjective image surveyed from the standpoint of the audience in order find if the intended story of the director is delivered to the audience through costume colors. Study method analyzed 25 set costume colors of the heroine 'Hideko'. The color analysis were analyzed by capturing DVD images that showed the costume of 'Hideko'. The colors of costumes were analyzed by recognition through the eyes based on the IRI, Hue, and Tone 120. In addition, the analysis of the IRI adjectives image were conducted through the survey. Costume hue of the heroine 'Hideko' in the film 'The Handmaiden' were black, yellow, white, green, and purple. There were many colorful costumes in the movie. Tones were very pale, deep, bright, vivid, strong, and pale. Chroma were evenly distributed and brightness were distributed in the order high, middle, and low. They were interpreted as the intention of showing the situation and psychology of 'Hideko' in various scenes of the film through various costume colors. Color images of the film 'The Handmaiden' were classified as feminine, mature, classy, delicate, classic, noble, polished, refined, showy, western, mellow, pure, and decorative.

Black-dyed PET fabrics were sputtered with stainless steel through DC-magnetron type device to investigate the possibility of coloration effect, and then considered the morphological structure and physical characteristics such as water permeation ability and washing fastness. Change in color was estimated on the basis of CIELAB color system. The color coordination of metal plated PET was shifted to yellow-red from red-blue. Colour difference$({\Delta}E^*)$ was increased by sputtering conditions with increasing ion current and treatment time. Especially, $Lightness(L^*)$ value of PET was remarkably increased by sputtering, whereas $Chroma(C^*)$ increased gradually. From SEM analysis, rough and uneven craters were found and thickened on the fiber surfaces with longer sputtering time. And washing fastness was a little poor and absorption ability slightly decreased. There were little changes of breaking load and breaking extension. It was evident that observed uneven craters in the plated thin layer resulted in the colour change of PET fabrics by sputtering treatments.

The purpose of this research was to investigate the impression dimension and to elucidate the image perception depending on the tone of the Korean jacket and Korean skirt using the tone-on-tone coloration. As stimulators, the became same color by making the skirt and jacket red, yellow, and green at the same time. After the skirt and jacket became four kinds of tones, vivid, light, dull, and dark by altering value and fuing chroma in the assembled color, these tone-on-tone coloration stimulators $48(3\times4\times4)$ were used for the investigation of this study. Impression factor of the stimulus consisted of the 5 different dimensions(youthfulness and activity, attractiveness, gracefulness, concentration of attention, tenderness). Among these factors, youthfulness and activity, attractiveness were proved to be more important. In the tone-on-tone coloration of a Korean skirt and a Korean jacket, each dimensional image was affected by the character of color, also the evaluation of countenance showed the meaningful difference depending on tone. Thus, we can comprehend that the influence of tone as well as color affects the evaluation of an image.

Examined in this study were the effects of copper oxide (II) addition and sintering conditions on the chromatic characteristics of copper glaze. Oxidatively sintered samples exhibited the negative increase of $CIEa^*$ and the positive increase of $CIEb^*$ with the increase of CuO concentration, leading to Green and Green-Yellow coloration. On the other hand, $CIEa^*$ and $CIEb^*$ of reductively sintered samples were positively increased in direct proportion. The green color of oxidatively sintered samples was originated from the $Cu^{2+}$ ions formed by the dissolution of CuO. The reductively sintered samples resulted in dull tone red color with low chroma. Such behavior seems to be influenced by the interplay of metal Cu aggregation, metal Cu globule, and $Cu_2O$ formed in the glaze layer through the redox interaction of CuO during the sintering process.

Clarified fruit and vegetable juices (apple, carrot and tangerine) were produced using ultrafiltration and their color change due to the mixing ratio were evaluated. clarification was carried out by passing he supernatant of extracted juice through a filter and also by using a membrane of molecular weight cut-off 10,000 Daltons to obtain the juice ultrafiltrates. The mixing ratio between apple and carrot juices was kept constant at 1:1 while increasing the amount of tangerine juice according to 10, 20, 30, 40 and 50% an stored at 4$^{\circ}C$ prior to the color measurement. Hue angle ({TEX}$h_{ab}${/TEX}) and {TEX}$L^{*}${/TEX}-value increased as the tangerine mixing ratio increased. The color difference indicated by ΔE-value also increased as the amount of tangerine increased indicating that the color of the mixed juice became pale and the changes were slight but distinctive. On the other hand, chroma ({TEX}$C^{*}${/TEX}), {TEX}$La{*}${/TEX}- and {TEX}$b^{*}${/TEX}-values decreased as the tangerine mixing ratio increased indicating that the color of the mixed juice became slightly more grayish and the samples were becoming les yellow. A simple mathematical model to predict each color characteristic is proposed.

This experiment was made on the basis of the general observation that silk fabrics is flaccid in sun light. The purpose of this test is to examine efficiency between the processed thread and the unprocessed one after putting the later under the xenon-lit system, which produces continuous spectrum of bright white beam similar to sun light. (i) Color division of silk thread : white, yellow blue (ii) light division and irradiation time : sun lightlongrightarrow210 hrs, Xenonlongrightarrow50,100, 150 hrs. Under the above conditions each object was be tested with and extensometer, TENSILON Type III for the results of (a) the weight-expansibility curve of the silk thread (b) the relationship between cutting in tensity and maximum, weight (c) maximum expansion rate (d) the expansion energy of the tested silk thread (e) the beginning pull-stretch resistance rate of the tested silk thread (f) color difference after processing The results are illustrated in the appropriate tables and figures. Consequently the generalobservation that silk fabrics is flaccid is relevant only in terms of color. So for as Cutting-intensaty is concerned, it turned out to be less flaccid than in color. On the contrary when the untested silk thread was conpared with the xenon-irradiated ones, the latter proved itself to be more flaccid in cutting expansibility than the former. We have learned through this experiment that, after the all rounds of this test, the color tone and chroma of the colored materials remained without significant change, where as their color value changed to a large extent.

The purpose of this study was to increase uv-cut ability of cotton, ramie, and rayon fabrics dyed with safflower red colorants. For this purpose, samples treated with uv-cut agent and tannic acid were compared with the untreated samples after ultraviolet(uv)-light exposure in terms of K/S value, color changes(${\Delta}E$), SEM, and tensile strength retention. K/S value rapidly decreased with increasing exposure time, but K/S value of the samples treated with both uv-cut agent and tannic acid decreased less than that of untreated samples. As increasing exposure time, $L^*$ and $b^*$ increased, $a^*$ decreased, and so ${\Delta}E$ increased, indicating less red character and more yellow character in color. This leads to change hue, value and chroma value. But color change of samples treated with both uv-cut agent and tannic acid was less than that of untreated samples. SEM pictures showed a severe degradation by uv exposure in all samples. Tensile strength slowly decreased for 21 days. And after this point, the decreased proceeded more rapidly. Tensile strength retention of the samples treated with uv-cut agent and tannic acid was higher than that of untreated samples.
