  • The purpose of this study is to examine color characteristics and color changes of the fashion collections through 1990s, and to provide the efficient color information for color planning upon fashion themes. For this research, a total of 30,084 colors were collected from Paris, Milan, London, New York Collections in 1990s. Those colors were first measured by the Pantone Textile Color Specifier and COS Color System and spectrophotometer(color eye 580). These measured color values $L^{\ast}a^{\ast}b^{\ast}$of CIE were converted into H V/C of Munsell System, and 12 tones of PCCS with 5 achromatic colors. The characteristics of collected colors were analyzed in general and by place, season and year. The results of the study are as follows : First, the hues of purple blue, yellow red, red, yellow and the tones of grayish, pale, white, black, dark grayish, dull, light grayish appeared mostly. Yellow was shown quite frequently in spring/summer while purple, purple blue, red and yellow red in fall/winter. White, pale, light, light grayish and light gray were shown more frequently in spring/summer while Black, dark grayish, grayish, dark gray and dark in fall/winter. Second, the characteristics of colors by 4 representative places were similar to the general characteristics of colors in 1990's. Third, There were distributed widely Red, Yellow Red, Yellow in the early 1990s, Green Yellow, Green, Blue Green in the mid of 1990s, and Purple Blue, Purple in the late of 1990s. The distribution range of chromatic colors showed wide in both of the early of 1990s and the mid of 1990s for a while, and achromatic colors of grayish, gray and black appeared mostly in the late of 1900s.

  • At the upper part of terrace deposits at Jeongdongjin area, there is a structure in which reddish brown and grayish white layers laying horizontally. Previous studies have reported the existence of these structures within the deposits and suggested the theoretical background related to the formation process. However, the analysis of physical properties and chemical composition such as particle size, classification, etc. of the materials constituting the reddish brown and grayish white layers is scarcely done. In this study, the physico - chemical properties of gray - white and reddish brown beds are investigated. The mean grain size of the particles was less than $4{\varphi}$ in both layers and the reddish brown layer was more coarse. The results shows that the sorting of the grayish white layer is better. The chemical composition of both layers shows that the average concentration of $SiO_2$, $Al_2O_3$ and $K_2O$ of the grayish white layer was higher than those of the reddish brown layer. The concentration of $Fe_2O_3$ of reddish brown lyaer was 3 times higher than those of the grayish white layer. The degree of chemical weathering (CIA) is 90 or so in both the reddish brown and grayish white layers, indicating a significant level of chemical weathering. In conclusion, reddish brown layers had been formed by the processes related to the migration of iron and the migration of water that induced aggregation after the formation of sediments (psudo-gleization). In this study area, a vertical layer of grayish white which cuts off horizontal reddish brown and grayish white color was found. The vertical layer or wedge similar to a ice-wedge or columnar structure that in a cold environment, and there is a difference in shape and size. The vertical layer appears to have occurred three or more cycles. The vertical layers begin to form at a certain height within the outcrop and descend downwards, which of course is difficult to see as directing certain times.

  • 16 healthy teeth extracted have been selected and their color and structural change have been observed at the fixed temperatures of $200^{\circ}F$., $400^{\circ}F$., $600^{\circ}F$., and $800^{\circ}F$. respectively at the intervals of 10min. 30min and 60min. The results were as follows: 1) $200^{\circ}F$ Groop: At the 60 minutes interval, crown surface shows pattern simliars to mottled teeth and roots take on light yellowish colar and interglobular dentin tends to be rough. 2) $400^{\circ}C$ Groop: at the 30 minutes interval, cracks begin to show in the direction of long axis of the teeth and crown surface have been observed on the verge of fracture at the 60 minutes interval. 3) $600^{\circ}F$ Groop: Crowns take on grayish-white color thoroughout 10, 30 and 60 minutes intervals and roots reveal black color. Moreover the seperation of enamel from dentin has been confirmed at the 60 minutes interval and inner dentin has changed black. 4) $800^{\circ}F$ Groop: Crowns take on the same grayish-white color as at the $600^{\circ}F$ at the 10, 30 and 60 minutes intervals and roots reveal gray color at the 30 and 60 minutes intervals, while parts of the crown have fractured at the 10 minutes interval. Inner dentin has turned gray at the 60 minutes interval.

  • 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.

  • The purpose of this study was to analyze the characteristics and images of colors in the stewardess's uniforms. For this study, 530 color samples were selected by extracting digital color data by using the Eyedropper Tool of Photoshop 7.0. The RGB color data were transformed into H V/C and the attributes of colors and tones were analyzed. The color images were analyzed with the color image scales of IRI and Shigenobu Kobayashi. As a results, purple-blue(21.7%), neutral(20.9%), red(17.9%) and yellow(10.8%) were found to be the most frequently used colors. In the tone analysis, vivid tone(18.7%) occupied high frequency and the next orders were white(17.4%), dark grayish(12.8%), light(8.5%), dark(8.1%). The color images were focused on dynamic, modern, casual, gorgeous, classic, elegance images in the color image scales of IRI and Kobayashi.

  • 본 연구는 코발트 코팅 두께에 따른 점토 표면과의 반응성을 연구하였다. 시편에서 표면으로 부터 일정한 두께로 코발트가 확산된 것을 볼 수가 있으며, 황화코발트의 도포양과 함께 청자토보다 백자토에서 확산층의 두께가 증가하였다. 백자토에 코팅된 시편은 grayish blue가 blue 색으로 변화되는 것을 알 수 있으며 $L^*$값이 51.78에서 37.61로 감소하고, 청자토에 코팅된 시편인 경우 dark olive gray에서 dark gray색으로 $L^*$값이 53.91에서 38.93로 적어지는 것을 알 수가 있다. 시편의 물성 평가는 XRD, SEM, 열팽창기, TG-DTA, UV-vis spectrophotometer와 HRDPM을 이용하였다.

  • 황칠나무 천연분포지에서 미생물의 감염으로 황칠의 분비가 촉진되는 것이 발견되었다. 황칠이 다량 분비되는 황칠나무의 상처 조직을 채취하여 배양한 결과 Sb1, Sb2, Sb3, Sb4의 4개의 균주가 분리되었으며, 황칠 분비 촉진에 관여하는 균주는 Sb3, Sb4의 2개의 균주였고 그중 Sb4 균주가 가장 우수한 균주로 선발되었다. Sb4 균주를 황칠나무에 접종한 결과 일반적인 칠액 채취 방법인 일(一)형처리 보다 흉고직경에 따라 3.4~7.7 배의 황칠 분비가 촉진되었다. Sb4 균주의 특성은 색깔이 회백색이고 균사가 구름모양의 둥근막을 형성하여 돌기를 이루며 생장하고 생장에 대한 온도의 영향은 $20^{\circ}C$ 이하에서는 거의 생장이 되지 않았고 $40^{\circ}C$ 이상에서는 생장이 급격히 떨어졌으며, 생장 최적 온도는 $30{\sim}35^{\circ}C$이었다. 생장 최적 pH는 6.5~7.0으로 나타났고 pH 5 이하와 pH 9 이상에서는 거의 생장하지 못하였다.
