The cocoon's color of silkworm, Bombyx mori L. is usually white. But some are yellow, flesh and green colors because of modified characteristics. The yellow and flesh cocoons depend on carotenoid pigments, green cocoons are determined by flavonoid pigments. The cocoon's color is affected by the genes controlling penetration process from midgut to coelom and silk gland. Y (Yellow blood, 2-25.6) and I (Yellow-inhibitor, 9-16.2) genes are involved in the penetration process of carotenoid pigments from midgut to coelom, C (Outer-layer yellow cocoon, 12-7.2) and F (Flesh, 6-13.6) genes from coelom to silk gland. Therefore, the carotenoid cocoon's color depends on the genotype Y, I, C and F genes and their combination. Among them, C gene is sympathetic gene, which are known as C, CI and CD. C (Outer-layer yellow cocoon) genes make yellow cocoons on outer-layer and white cocoons on inter-layer, and CI (Inner-layer yellow cocoon) genes do yellow cocoons on inter-layer and dilute yellow cocoons on outer-layer. CD gene is known as making dilute yellow cocoons all layer. In this study, we have checked the dominance relation of C sympathetic genes among carotenoid genes for color cocoons by using strains related to the genes for color cocoons and investigated the aspect that pigments were penetrated in silk gland by action of each gene.

본 논문에서는 HP 컬러 레이저 프린터 기기의 출력물에 나타나는 Yellow Dots의 형태를 분석하고자, 각각 시간의 경과, 연과 월의 경과 그리고 동일한 기종에 따른 Yellow Dots의 특성을 실험하였다. 그 결과, 동일한 프린터기기의 출력물에서는 시간의 경과, 연과 월의 경과에서 나타나는 Yellow Dots의 형태가 동일한 것을 알 수 있었다. HP 컬러 레이저젯 프린터 기기에는 Xerox사에서 출시된 컬러 레이저젯 프린터기기와는 다르게 시간과 날짜 정보가 임베딩 되지 않았다는 것을 가정 할 수 있었다. 또한 시리얼 넘버가 다른 프린터기기에서는 유사하지만 다른 형태의 Yellow Dots가 나타나는 것을 알 수 있었으며, 이것은 프린터기기 구분에 있어 큰 도움이 된다. 마지막으로 실험에 사용된 모든 HP 컬러 레이저 프린터 기기들의 Yellow Dots를 분석한 결과, 동일한 패턴을 찾을 수 있었으며, 그 결과를 통하여 제조사를 파악 할 수 있었다. 향후 Yellow Dots 패턴을 해독하고 나아가 타 제조사의 Yellow Dots를 검출 및 분석하는 연구가 진행되어져야 한다.

The purpose of this study was to comparatively analyze the characteristics of traditional costume colors of Korea China Japan with quantitative methods. The range of this study was limited to the costume colors from 16th to 19th century. For this study 1333 color samples were collected by measuring with a spectrophotometer. The results of this study are as follows: Red, Yellow Red, Yellow and Purple Blue had been used in common for the traditional costume colors of Korea, China and Japan. Yellow of Korea, Purple Blue of China, Yellow Red of Japan showed the high frequency. Red, an asian preference color, had most frequently used in korean traditional costumes. Pale toned Yellow and Yellow Red, high saturated Red and low valued Purple Blue had been preferred for korean traditional costumes. The preferences of high saturated Red and low valued Purple Blue were based on the Five Element theory and the pale toned Yellow and Yellow Red were used with the preference of White and natural colors. In China the traditional costume colors had used with the Five Element theory also but they had preferred Purple Blue, deep & strong toned Red to Yellow Red and Yellow, Yellow Red, Purple and grayish colors had been frequently used in japanese traditional costumes. In the results of color distributions in $L^*a^*b^*$ color space, korean and chinese traditional costumes colors concentrated in some areas like Yellow, Yellow Red, Red and Purple Blue. Japanese costumes colors showed the even distribution with the diverse toned colors. Korean traditional costume colors corresponded with the Five Element theory rather than China and Japan. Japan had used the costume colors with the racial sensibility rather than conceptual color theory.

This study was conducted to examine the favorable taste of food color for one month of November 1991 With 200 college students consisting 100 male and 100 female students. The color to examine the favorable food was based on Munsell color standard of ten colors such as F. Birren seven colors (red, orange, yellow, yellowish green, green, blue and violet), brown, pink and black. And then, the data of this study was analysed by using frequency(%), mean values, standard deviation, t-test, Chi-square, Spearman correction with SAS Package on the basis of 100% collection and reliable coefficient alpha= .775. The result of this study is summarized as follows. 1. It was shown that the male college students (59%) showed remarkable interest in the food color higher than that of female college students (92%), and that 85% of male students and 97% of female students considered that the food color has an effect on appetite. In addition, the food name having an effect of the food color on appetite appeared in such order as carrot (13.0%), apple (10.9%), spinach (7.0%), cucumber (6.0%) and red pepper (5.6%). The important factor in choosing the favorable food was the taste for both male and female college students, while the male and female students considered the food color as the 4th, respectively, and the 3rd important factor in choosing the favorable food. 2. The favorable food color appeared in order such as orange, red, yellow, yellowish green, green, blue, violet, pink, black and brown colors for the male college students, and in order such as red, orange, yellow, green, yellowish green, brown, violet, black, pink and blue. Also, there was difference between the male and female college students in such colors as brown, yellowish green, blue and pink. It was also shown that there was no relation between the male and female college students in examining the order of favorable food colors and general colors when selecting null hypothesis (ASE: .405). The food name associated with the color was apple for red color, orange for orange color, coffee for brown color, banana for yellow color, lettuce for yellowish green color, spinach for green color, mackerel for blue color, eggplant for violet color, sausage for pink color and bean for black color 3. The favorable color combination of both male and female college students showed red with green, orange with yellow, yellow with green, green with yellow, pink with violet and black with black. In addition, the favorable combination of the male college students indicated brown with black, yellowish green with orange, blue with red and violet with yellow while the female college students did brown with yellow, yellowish green with green, blue with yellow and violet with pink. The favorable combination color showing difference between the male and female college students included orange, brown, violet, pink and black colors. 4. The relation between the food color and terms of favorable taste showed that “light and mild color” is yellow, that “untasty color” is black, that “sourish and puckery color” is orange, that “bitter color” is violet, that “hot color” is red, and that “fresh color” is green which were answered by both male and female college students. However, the male and female college students considered yellow, respectively, and orange as “tasty color”, and black and yellow, respectively, as “sweet color”. Then, the taste term showing difference between male and female college students included “light”, “mild”, “sourish”, “tasty” and “sweet”. Based on the above result of this study, it is apparent that there is a close relation between the food color and appetite while being difference between the general color and taste. In addition to this fact, there is also some differences between male and female college students in the taste of food color.

The stability of yellow and red dyes prepared from safflower (Carthamus tinctorius L.) in aqueous solution and in solid state was investigated. External factors such as light irradiation and temperature on the stability were examined during storage. Changes in absorbance of dye solutions and the color changes of fabrics dyed after long time storage were measured. Also, color reproducibility during storage was investigated by dyeing test on various fabrics. Red colorant in aqueous solution was very unstable to light, resulting that about 40% of absorbance were lost in 12hrs. The absorbance of yellow dye solutions was not decreased within 84hrs. In aqueous medium, yellow dye was much more stable than carthamin. Both dyes are relatively stable for long storage when they are stored in solid state compared to when in aqueous solution. Color changes are marginal in both dyes.

The confucianism, the Taoism, the Budd-hism and the Folk-Faith actually coexisted and all of them had also widespread infuluence on the Chosun Society. This thesis is designed to study symbol of Color Scheme expressed in the clothing of Chosun dynasty. For this thesis I examined records of Royal archives, books containing lifestyle of Chosun dynasty, genre paintings, documantary pain-tings, excorcist clothing and existing remains. And I synthetically studied symbol of the Clothing Color Schemes in Chosun dynasty on the bases of theoretical researches. The result were as follows. There were many cases of 1. Upper·lowergarments : Red-Blue, White-Blue, White-Blue Color Schemes. 3. Exorcist clothing : Red-Red, Blue-Yellow, Blue-Blue Color Schemes. 4. Multy-colored stripes : Same color arrange-ments were avoided in Color Schemes. In the case of Green Wonsam, Blue-Red-Yellow-White Clothing Color Scheme was obvious. 5. Dance wear : Red-Blue, Yellow-Red Color Schemes. Generally more than anything else Blue-red Clothing Color Scheme was widely used. Be-sides Blue-Red Color Scheme, there were also many cases of Red-Yellow, White-Blue Cloth-ing Color Schemes. As a whole, compatible Color Schemes were more often used than in-compatible Color Schemes were used with various symbols that were based on color concept of Yin-Yang O-haeng, Tae-il theory Folk-Faith and so forth in Chosun dynasty.

In the present communication literatures pertaining to the coat color of Jindo dogs, the natural monument of Korea, have been reviewed. It was reported that there were seven different coat colors in Jindo dogs. They are yellow, white, red, black, tiger-like, grey, and spotted. The yellow and red dogs have typical color markings called "Yibaik", and black dogs have yellow or white color markings called "Nenoonbagi". All Jindo dogs, which have 7 different coat colors with typical color markings, could be found nowadays. The pictures of those Jindo dogs were taken and presented in this communication. It was felt that the coat colors of Jindo dogs should not be limited to yellow and white. And Jindo dogs should be judged not by their coat color but by their noble characteristics.
