The purpose of this study is to classify the characteristics of color communication tools and the color range applied in the Korean fashion industry. To collect the color sample and related references, a questionnaire was distributed during the time period, December, 1995 to June, 1996. From the responses, 2641 color samples used by 109 domestic brands, from 1993 spring/summer to 1996 spring/summer, were collected and analyzed. The data was measured by L*a*b*, and the H V/C formula found in the Munsell notation was used to calculate the data. To classify the color range served for the fashion industry, the distribution of colors are analyzed by difference of season and fabric. The results of this study are as follows : 1. Dominant colors in the Korean fashion industry are Red, Yellow-red, Yellow, purple-blue and low chromatic range colors. 2. While high value colors, such as pale, light greyish, light, dull, dark and vivid tone colors, are dominant in the spring/summer season, low value colors, such as greyish, dark greyish. and deep tone colors and warm colors such as Red, Yellow-red, are prevalent in the fall/winter season. 3. The number of colors commonly used for color planning is less than 20 colors, and both hue and tone are considered important when making color selections. 4. All brands take consumers' color preferences into consideration for color planning, and most of them also take color trends into account. 5. Hue and tone color characteristics analyzed by types of fabrics show more seasonal influence than the fabric itself.

Purpose: The color changes in red pepper during far infrared drying were studied in order to establish a color change model. Methods: The far infrared drying experiments of red pepper were conducted at two temperature levels of 60, $70^{\circ}C$ and two air velocity levels of 0.6 and 0.8 m/s. The results were compared with the hot-air drying method. The surface color changes parameters of red pepper were measured qualitatively based on L (lightness), a (redness), b (yellowness) and total color changes (${\Delta}E$). The goodness of fit of model was estimated using the coefficient of determination ($R^2$), the root mean square error (RMSE), the mean relative percent error (P) and the reduced chi-square (${\chi}^2$). Results: The results show that an increase in drying temperature and air velocity resulted in a decrease in drying time, the values of L (lightness) and a (redness) decreased with drying time during far infrared drying. The developed model showed higher $R^2$ values and lower RMSE, P and ${\chi}^2$ values. Conclusions: The model in this study could be beneficial to describe the color changes of red pepper by far infrared drying.

The costumes on a royal ceremony and the changes thereafter during the Korea Empire(1897-1910) have been elucidated through the review on the paintings on Queen Myong-Hun's 70th birthday celebration and the prospectus of the ceremony. Queen Myong-Hyn wore ceremonial gown in deep blue with 51 embroidered phoenix on it. The deep blue color the royal color in the Korea Empire replaced former red color. Go-jong wore violet crown and ceremonial suit in gold color. Twenty one kinds of court dance were offered during the celebration ceremony. Costumes therein appear to have an order according to the role ofdancers. most female dancers(in 17 performances not else-where specified) wore a rather common cos-tume-flower cap outer silk garent in green hand veils in 5 colors silk skirt in red) embroidered silk belt in red and shoes in green. In Sun-you-ak two female lead dancers were red hat decorated with tiger whisker deep blue outer garment wide red belt silk boots in black bow and arrows on back and a sword and a whip in hands. In Choonaang-jon a fe-male solo dancer wore a silk outer garment in yellow silk skirt in red green lorum embroidered silk belt in red wrist band of gold embroidered red silk and 5 color hand veils. In Yon-wha-dae two young girl dancers wore lotus-form crown green outer garment wide pants in red silk red silk skirt red silk belt hand veils in jade color and silk shoes in deep red. In Moo-go 4 female dancers each wore long waist coat in blue red white and warm light green in addition to the above-mentioned common costume. In Gumkee-moo 4 female dancers wore hatlike wool helmet outer garment with narrow sleeve long silk waist coat in blue combat belt in deep blue silk and dance swords in both hands. In Youk-wha-dae 6 female dancers each wore a long waist cost in red deep blue violet pale pink green and jade color. Green color of outer garment in the above-mentioned common costume of female dancers appears intersting. Although the color was shown as yellow in the screen paintings actually it was green as evidenced by the prospectus of the celeebration ceremony.

Purpose: This study was to investigate color distortion by colors and luminous transmittance of lenses with word-color test included in computerized neurocognitive function test (CNT). Methods: 32 subjects aged $21.97{\pm}1.58$ years with no ocular disease and color vision deficiency were selected. Four colors of tinted lenses, which were red, green and blue included in the primary colors of light and pink, and word-color test in CNT to evaluate changes in cognitive function by color distortion were used. Results: Response time was not significantly increased in green, blue, and pink among four colors, but significantly increased in only red color. And response time was significantly increased below 46% of luminous transmittance in red color. Conclusions: It should be cautious and careful of the red-tinted lens choice because red color with below 46% of luminous transmittance can distort colors of objects, and it could be related to safety problem. It is suggested that word-color test could be extensively used for further studies on color recognition.

We studied the emission characteristics of white phosphorescent organic light-emitting diodes (PHOLEDs), which were fabricated using a two-wavelength method. To optimize emission characteristics of white PHOLEDs, white PHOLEDs with red/blue, blue/red and red/blue/red emitting layer (EML) structures were fabricated using a host-dopant system. In case of white PHOLEDs with red/blue structure, the best efficiency was obtained at a structure of red (15 nm)/blue (15 nm). But the emission color was blue-shifted white. In case of white PHOLEDs with blue/red structure, the better color purity and efficiency were observed at a blue (29 nm)/red (1 nm) structure. For additional improvement of color purity in white PHOLEDs with blue (29 nm)/red (1 nm) EMLs, we fabricated white PHOLEDs with red (1 nm)/blue (28 nm)/red (1 nm) structure. The current efficiency, external quantum efficiency, and CIE (x, y) coordinate were 27.2 cd/A, 15.1%, and (0.382, 0.369) at 1,000 $cd/m^2$, respectively.

Purpose - Color is perceived to have an effect on humans' cognition and behavior because of its association with specific concepts. Since there are few studies linking color and price presentation, we investigated a constrained condition of consumers' regulatory focus and involvement. Research design, data, and methodology - We performed a 2 (color: red vs. black) × 2 (regulatory focus: prevention vs. promotion) × 2 (involvement: high vs. low) test of our hypothesis. The target product was a portable data storage device (USB) and data from 165 respondents were analyzed. Each condition had two stages. In the first, product information and price were presented. After reviewing the product information, respondents evaluated price attractiveness. In the second stage, respondents filled out regulatory focus and involvement questionnaires. The main variables were color, regulatory focus, and involvement. Therefore, we ran a three-way ANOVA (Analysis of Variance) to test our hypothesis. Results - When the price was red (vs. black), consumers perceived the red price as more attractive than the black price. However, this effect varied by situation. Specifically, in the low involvement condition among prevention-focused consumers, when the price was in red, price attractiveness was higher than when the price was in black. However, for promotion-focused consumers, there was no difference in the price color effect. In the high involvement condition, promotion-focused consumers showed stronger price attractiveness for the red price than the black price. However, the effect of price color diminished for prevention-focused consumers. That is, prevention-focused consumers did not reveal a different price perception between red versus black in the high involvement condition. Conclusions - This research contributes by academically linking the effects of color to price attractiveness, and focusing on the interaction of regulatory focus and involvement. When involvement is low, the effect of red disappeared for promotion-focused consumers, whereas the same happened for prevention-focused consumers under the condition of high involvement.

This study investigates when and why the light pink Dan-ryoung appeared as part of the official uniform of the Joseon Dynasty and which official uniform used the light pink color. The Annals of the Joseon Dynasty, books written by scholars, and related laws were used as research materials. The following results were obtained by analyzing the arguments of kings and officials on light pink uniforms and laws related to official uniforms. 1. Red was the color of the king as well as the color of Dang-sang-gwan's Gong-bok (one of the official uniforms). 2. The colors such as To-hong, Dam-hong, Do-hong, Bun-hong, Cheon-hong that appeared in Sang-bok (among official uniforms) were relatively lighter than red. 3. To-hong started to be used in Sang-bok at the time of King Se-jong and was used at the time of King Seong-jong in Sang-bok because it was the preferred color. 4. In the Joseon Dynasty, safflower (the basis of red color dye) was cultivated extensively; in addition, people liked red dyeing because it was relatively easy apply; subsequently, a ban on red dyeing was continually issued. 5. Kings Se-jong and Jung-jong ordered officials to use Do-hong and Bun-hong to distinguish the red color of the king. After Im-jin-oe-ran, Cheon-hong was officially designated the color of Sang-bok. 6. The reasons why Dam-hong was used in official uniforms were twofold: the preference for red-like colors and the influence of the Confucian hierarchy to distinguish the king.

In this study, the automatic tracking algorithm tracing a human face is proposed by using YCbCr color coordinated information and its thermal properties expressed in terms of thermal indexes in an infra-red image. The facial candidates are separately estimated in CbCr color and infra-red domain, respectively with applying the morphological image processing operations and the geometrical shape measures for fitting the elliptical features of a human face. The identification of a true face is accomplished by logical 'AND' operation between the refined image in CbCr color and infra-red domain.
