The purpose of this study is to examine the relation between the trend of art and fashion which predominate a certain time. In order to achieve this goal, this study intends to analyze how plasticity found in Mondrian's pictures are applied to modern fashion with its focus on formative elements. Mondrian was ahead of abstractionism, a major trend of contemporary art, and defined the theory of neo-plasticism. The theory of neo-plasticism defined by Mondrian is characterized by the limited expression of lines and shapes by using only vertical and horizontal straight lines, and right angles and four-sided figures weaved by the lines, and the use of achromatic color(black, white, and gray) in three primary colors(red, blue, and yellow). Based on his theory, he fully displayed the world of geometric abstraction. Mondrian's formative elements which have been applied in modern fashion can be divided into shape and color, For the element of shape, first, horizontal and vertical lines have been applied to patterns, trimmings, detail, and plane of textiles through simplification of design, representing proportion, balance, and stress in a silhouette, Second, plane and diamond shapes made of horizontal and vertical lines have been applied to textiles or patterns with uniqueness. For the element of color, first, three primary colors and achromatic colors are used to seek the aesthetics of balance and harmony that are produced in the strain of conflict through brightness, chroma, and complementary colors, Second, primary colors of high chroma and brightness which are much stronger than pictures are used to express a modern sense. Formative elements of neo-plasticism, which have been applied to modern fashion suggested by this study, are connected with the trend of art contemporary designers have borrowed, Accordingly, this study will become a very helpful material which provides designers with original ideas in developing materials and patterns which connect design with art.

Recently, various techniques for face detection are studied, but most of them still have problems on processing in real-time. Therefore, in this paper, we propose novel techniques for real-time detection of human faces in sequential images using motion and chroma information. First, background model is used to find a moving area. In this procmoving area. edure, intensity values for reference images are averaged, then skin-color are detected in We use HCr color-space model and adaptive threshold method for detection. Second, binary image labeling is applied to acquire candidate regions for faces. Candidates for mouth and eyes on a face are obtained using differences between green(G) and blue(B), intensity(I) and chroma-red(Cr) value. We also considered distances between eye points and mouth on a face. Experimental results show effectiveness of real-time detection for human faces in sequential images.

This study investigated the colors of the costumes and backgrounds of characters in the films "Thirst" and "Mother" from an integrated perspective. As a study method, ten scenes per film, which contained the characters and backgrounds from the start to the end of the DVDs of "Thirst" and "Mother" were examined. For integrated color analysis of the costumes and backgrounds, the colors of the captured scenes were simplified to extract representative colors, and then color palettes were presented according to the ratio of area. The colors of costumes were analyzed by recognition through the eyes based on the I.R.I. Hue and Tone 120. Furthermore, the color images of the two films were analyzed using the I.R.I. adjective image scales and the I.R.I. color image scales. The colors of the film "Thirst" were generally low in brightness and high in chroma. They are characterized by dark, gloomy toned-down background in the first half, highly chromatic vivid background in the second half, and the contrast of purple blue colors and red colors. The colors of the film "Mother" are characterized by complementary colors between background and costume colors, and various tones of blue and green colors. From the aspect of color tones, they were relatively high in brightness compared to the film "Thirst" but low in chroma. On the I.R.I. adjective image scale, contrasting adjectives were extracted simultaneously from the film "Thirst" as the adjectives were evenly distributed at hard, dynamic and static, whereas the adjectives extracted from the film "Mother" were distributed at hard and statistic. On the I.R.I. color image scale, both films were located at hard, but the film "Thirst" was located at dynamic whereas the film "Mother" was located at static.

The importance of color is increasing in modern life and we call such present age that is 'color age'. These day that all areas of life are being getting fashionize, ordinary people as well as design specialist are required of culture and knowledge about color. Color design education is important curriculum at liberal arts course and in special design trainning course. Color expresses by hue, value and chroma in Munsell color system. But design spot is using mainly hue and tone color system. Therefore it is very important that educate tone concept in color design education. When think influence that increase of color, we must develop hue and tone color system in suitable for color design education. This research designed usable 'Hue and Tone 313 Colot System' for efficeint sensual color education. Also I designed 313 color papers with attached the Munsell notation which could reappear the spare color paper when needed. The 10 hues classification of this system are Red, Yellow Red, Yellow, Green Yellow, Green, Blue Green, Blue, Purple Blue, Purple, Red Purple. The 19 tones classification of this system are vivid, light, standard, deep, pale, soft, dull, dark, very pale, light grayish, medium grayish, dark grayish, very dark, off White, off Pale, off Light Gray, off Medium Gray, off Dark Gray, off Black. The special colors of this system are gold, silver and copper.

This study attempted to find a way to maintain the quality of mixing baby wild leaf vegetables with existing baby leaf vegetables in various ratios. The crops for mixing baby leaf vegetables were Peucedanum japoincum Thunberg and Ligularia stenocephala, as wild vegetables, and red romaine, which is widely used in young leafy vegetables. The mixing ratio of red romaine and wild vegetables was red romaine 0: mantilla oil 5: L. stenocephala ratio 5 (R0: P5: L5), red romaine 3.3: P. japoincum 3.3: L. stenocephala ratio 3.3 (R3.3: P3.3: L3.3), red romaine 5: P. japoincum 2.5: L. stenocephala 2.5 (R5: P2.5: L2.5), red romaine 8: P. japoincum 1: L. stenocephala 1 (R8: P1: L1), red romaine 10: P. japoincum 0: L. stenocephala 0 (R10: P0: L0). All treatments were packaged in OTR (oxygen transmittance) 10,000 cc m-2·day-1·atm-1 film and stored for 27 days at 2℃/85% RH conditions. Fresh weight, carbon dioxide, oxygen, and ethylene concentrations of the baby leaf packages were examined approximately every 3 days, and visual quality, chlorophyll content, and chromaticity were examined on the 27th day of storage. The oxygen and carbon dioxide concentration in the packages were affected by the respiration rate of the crop. As the mixing ratio of lettuce, which had a low respiration rate, increased, the oxygen concentration in the packages was higher and the carbon dioxide concentration was lower. Oxygen concentration decreased significantly after 15 days, but was remained above 16%, and on the contrary, carbon dioxide concentration was kept at 1-4% until the 15th, and then gradually increased to 2-5% on the 27th day. The concentration of ethylene was maintained at 3-6 µL·L-1 until the end of storage (27th day). Visual quality score measured at the end of storage was slightly less than 3.0, which is the limit of marketability of all treatments. Although there was no significant difference, the chlorophyll content (SPAD) of red romaine and P. japoincum were most similar with an initial value in R8:P1:1 treatment, and L. stenocephala was higher value in R8:P1:L1 and R5:P2.5:L2.5 treatments at the end of storage. The leaf color (L∗, a∗, b∗, chroma) of the three crops at end of storage compared with the heat map showed the least change in the R5:P2.5:L2.5 and R8:P1:L1 treatments at the end of storage. Among them, R8:P1:L1 treatment maintained the highest chlorophyll content, the second lowest ethylene concentration, and adequate carbon dioxide concentration of 2-3%. Therefore, it is judged that the mixed ratio of red romaine 8: P. japoincum 1: L. stenocephala 1 (R8: P1: L1) is most suitable for the mixed package of baby leaf vegetables of these three crops.

The purpose of this study was to investigate the changes in properties of silk fabrics dyed with safflower red and yellow colorants under Ultraviolet(UV)-light. Silk fabrics dyed with safflower red and yellow colorants were compared with each other after uv-light exposure in terms of K/S value, color changes(${\Delta}E$), morphology, and strength retention. The K/S value rapidly decreased with increasing exposure time for samples of both colorants, but the extent of decrease was less for the samples dyed with safflower yellow colorant, than that of the samples dyed with safflower red colorant. Regarding the color changes with increasing exposure time, $L^*$ and $b^*$ increased, $a^*$ decreased, and thereby ${\Delta}E$ increased in the red-dyed samples, whereas $L^*$ increased, $a^*$ and $b^*$ decreased, and so ${\Delta}E$ increased in the yellow-dyed samples, indicating that the UV-light induced fading and changes of hue, value and chroma value. However, the color change of the yellow-dyed samples was less than that of the red-dyed samples. SEM images showed a severe degradation by UV-exposure for both colorant samples. Tensile strength slowly decreased until 14 days, but rapidly decreased thereafter. Strength retention of the yellow-dyed samples was higher than that of red-dyed samples.

The purpose of this study was to investigate the changes in the property of nylon fabrics dyed with safflower red and yellow colorants under Ultraviolet(UV)-light. For this purpose, nylon fabrics dyed with safflower red and yellow colorants were compared with each other after uv-light exposure in terms of K/S value, color changes(${\Delta}E$), morphology, and strength retention. K/S value rapidly decreased with increasing exposure time, but K/S value of the samples dyed with safflower red colorants decreased less than that of samples dyed with safflower yellow colorants. In color changes, as increasing exposure time, $L^*$ increased, $a^*$ decreased, $b^*$ increased, and so ${\Delta}E$ increased in samples dyed with safflower red colorants. In color changes, as increasing exposure time, $L^*$ increased, $a^*$ and $b^*$ decreased, and thereby ${\Delta}E$ increased in the samples dyed with safflower yellow colorants, indicating fading away by uv-light and changes of hue, value and chroma value. But the color change of samples dyed with safflower yellow colorants was less than that of samples dyed with safflower red colorants. SEM pictures showed a severe degradation by uv exposure, regardless of colorants type. Tensile strength slowly decreased until 14 days, and rapidly decreased until 28 days. Strength retention of the samples dyed with safflower yellow colorants was higher than that of the samples dyed with safflower red colorants.

This study was performed to investigate the effect of mordants on the dyeability colorfastness to light and to laundering and biological properties of mordanted and natural-dyed cotton and silk substrates. Natural red dyes were extracted from Caesalpinia Sappan L. (Sappan wood) and Rubia Akane Nakai (Madder) by boil water Five different compounds of Al, Cr, Cu, Fe and Sn were used as mordanting agents. The result of this study are sumarized as follows ; 1. In the of the fabrics mordanted and dyed with sappan wood K/S value increases and λmax shifts to the longer wavelength as mordant concentration increases. Color of the fabrics dyed with sappan wood and madder change to redder bluer and lighter after mordanting. 2. As the number of repetition of dyeing-mordnating process increase the color of the dyed fabrics tend to be redder bluer and darker. Mordanted dyes with Al and Sn make chroma increase. The quantity of mordant absorbed in the silk fabric increase as mordant concentration increase. More Fe is absorbed in silk than Cr is. 3. After being exposed to light the fabrics dyed with sappan wood and madder change to less red Fe and Cu mordanting yeild better colorfastness to light than others does. Natural-dyed fabrics exposed to light tend to be faded and whitened in CIELAB chromaticity co-ordinates. So we might trace back the original color of ancient faded fabrics by changes in color of natural dyes. 4. After washing the colors of natural dyes change to more blue, Fe and Cu mordanting give better colorfastness to wash than others do. 5. The soil-burial cotton is more susceptible to mildew and rot than the silk is. Antimicrobial activity of the natural-dyed cotton can be enhanced by Cu and silk can be enhanced by Cu and Cr mordanting respectively.

The purpose of this study was to closely examine the history of glasses and their cases used in the middle and late of Joseon Dynasty and identify inherent quality of our traditional glasses cases through color analyses of glasses cases' material and shape. While theoretical examination was conducted based on the literatures of glasses and their cases that firstly appeared in around Japanese Invasion (Imjin war) of Korea in 1592, practical analyses were demonstrated on photos of glasses cases used in the middle and late of Joseon Dynasty collected from both museum pieces and the internet which were grouped into wood, fabric, paper, sharkskin, hawksbill and cow's horn in accordance with their materials. 623 color samples were abstracted from collected 159 glasses cases and quantity analyses on each material were performed respectively. Abstracted representative colors based on the result of color analyses were classified into the main materials and accessories' color scheme. The result of this study are as follow: firstly, both Yellow and Yellow Red were mostly used in main materials. In Fabric case's colors were widely used in embroidery and in animal matter material cases such as sharkskin, hawksbill and cow's horn, which can be used as itself or dyed, Green Yellow shown in high frequency. Secondly, accessories were analyzed into similarity coloration with main materials. From this finding, it turns out that our traditional cases have characteristic of similarity coloration between main materials and accessories. Red Purple and Purple Blue in high frequency in accessories used as an accent color. Finally, based on the analysis of hue and tone, while the middle and low value colors shown in very high frequency, the high-chroma colors hardly shown.

The purpose of this research is to understand the harmony of chromatic and achromatic colors of the traditional Korean dress. The subjects were women＇s college students in Korea and America. Chromatic colon, red, yellow, and green color, were chosen for the color of the Korean jacket, and achromatic colors were chosen for the color of the skirt, and then the colors＇ chroma were controlled and value of color was changed. In addition, the three colors of the jacket were combined with four kinds of the colors＇ tone. Then, the students of both countries assessed about the harmony for 48 colorations which were variously incorporated with the tones of skirt and jacket. The results of research can be summarized as follows. When red jackets were combined with skirts of achromatic colors, students of both counties showed the different views in the range of harmony and disharmony for colorations of white(N9) skin and vivid jacket, and white(N9) skirt and dark jacket, and black(N2) skirt and light jacket, and black(N2) skirt and dull jacket. In the tone of yellow jackets and achromatic skirts, students of both counties showed similar responses in that a light yellow jacket was well matched with dark grey(N4) and black(N2) skirt. While Korean students generally evaluated that coloration was well harmonized when low value color was arranged below, American students thought, that the tones of a harmonized skirt were different, according to the jacket＇s tones. When green jackets were combined with stills of achromatic colors, colorations that showed their different views of both countries were a white(N9) skirt combined with vivid, light, dull jackets, and a light grey(N7) skirt and dull jacket, and a dark grey(N4) skirt and dark jacket. Among 48 stimuli of coloration on the chromatic and achromatic colors, Korean students evaluated 16sets and American students judged 28 sets as harmonized colors. Therefore, it came to the conclusion that Korean students had the sense of harmonious coloration of more narrow range than American students.
