  • This experiment was carried out to investigate the effects of gamma-radiation on the rooting, growth, and color mutation in poinsettia. Using 10 poinsettia varieties ('Lollipop', 'Little Peace', 'Happy Day', 'Early Bird', 'Pixy Red', 'Happy Time', 'Heidi', 'Red Bell', 'Clara', and 'Scarlet') bred by National Institute of Horticultural and Herbal Science, 100 Gy of gamma ray was irradiated at the stage of callused cuttings. Four weeks after sticking cuttings in the rooting media, 8 cultivars showed 100% of root formation, but 'Early Bird' rooted 24.4% and even died off during the cutting propagation. After planting rooted cuttings, survival rate until flowering time varied among irradiated cultivars. While 'Pixy Red' and 'Heidi' survived about 98%, 'Clara', 'Happy Day', and 'Early Bird' survived lesser than 30%. All irradiated plants showed remarkably shorter plant height, lesser branch numbers than non-irradiated control plants. Thirty color mutants were obtained among 281 plants survived until flowering time. Nine mutants were complete color mutated branches, whereas 21 mutants were partially color mutated bracts and transitional leaves. Color patterns mutated by 100 Gy of gamma ray were divided into pink, hot pink, light red and spotted (pink spots with red main color). Pink mutants were commonly obtained. Complete color mutants were discovered from 4 plants of 'Pixy Red', 2 plants of 'Red Bell' and 3 plants of Lollipop.

  • For the purpose of development of red color stain body, bone body which can be fired at 1180$^{\circ}C$ and has a higher degree of whiteness and transmission was developed and a property experiment depending on the content of $Fe_2O_3$ was performed. For manufacturing this body, 9% addition of bone ash to commercialized white body resulted in the best whiteness and proper physical characteristics. In an experiment of oxidized iron addition using this body as a basis, red color stain body fired up to 1150$^{\circ}C$ following the addition of 6% oxidized iron showed physical characteristics such as 5.4R color closer to theory color, 0.08% water absorption rate, 9.1% shrinkage, and 1861 kgf/$cm^2$ bending strength, which implies that this body is suitable for red color stain body.

  • Two experiments were conducted to study the effects of red pepper (Capsicum frutescens) powder or red pepper pigment on the performance and egg yolk color of laying hens. In Exp. 1, 210, thirty-wk old, Hy-line Brown laying hens were fed one of seven diets containing 0.3, 0.6, 1.2, 2.0, 4.8 or 9.6 ppm red pepper pigment or 0.3 ppm carophyll red. Each diet was fed to three replicate batteries of hens with each battery consisting of a row of five cages of hens with two hens per cage (n = 3). In Exp. 2, 180, thirty-wk old, Hyline Brown laying hens, housed similarly to those in Exp. 1, were fed an unsupplemented basal diet as well as treatments in which the basal diet was supplemented with 0.8% red pepper powder processed in a laboratory blender to an average particle size of $300{\mu}m$, 0.8% red pepper powder processed as a super fine powder with a vibrational mill ($44{\mu}m$) and finally 0.8% red pepper powder processed as a super fine powder with a vibrational mill but mixed with 5% $Na_2CO_3$ either before or after grinding. A diet supplemented with 0.3 ppm carophyll red pigment was also included (n = 3). In both experiments, hens were fed the red pepper powder or pigment for 14 days. After feeding of the powder or pigment was terminated, all hens were fed the basal diet for eight more days to determine if the dietary treatments had any residual effects. In Exp. 1, there were no differences in egg-laying performance, feed consumption or feed conversion ratio due to inclusion of red pepper pigment in the diet. Average egg weight was higher (p<0.05) for birds fed 1.2, 2.4 or 9.6 ppm red pepper pigment than for birds fed the diet containing 0.3 ppm red pepper pigment. On d 14, egg color scores increased linearly as the level of red pepper pigment in the diet increased. In Exp. 2, feeding red pepper powder did not affect egg-laying performance, feed consumption or feed conversion ratio (p>0.05). However, compared with the control group, supplementation with all of the red pepper powder treatments increased egg weight (p<0.05). All the red pepper powder treatments also increased (p<0.05) the yolk color score compared with the control. The results of the present study suggest that both red pepper powder and pigment are effective feed additives for improving egg yolk color for laying hens.

  • 인간은 다른 포유류와 달리 삼원색 시각을 가지며 초록과 빨강을 잘 구분한다. 인간이 삼원색 시각을 갖게 된 원인에 대해서 익은 과일 가설(frugivory hypothesis) 지지자들은 초기 인류가 초록 잎에서 빨갛게 익은 과일을 구별하여 섭식하려는 행동 때문이라고 주장한다. 본 연구는 과연 빨강-초록 조합이 물체재인의 전 단계로 알려진 전경-배경 조직화에 영향을 주는지를 살펴보고자 하였다. 빨간색 원이 초록 바탕에 놓이거나, 초록색 원이 빨강 바탕 위에 놓여 참여자에게 제시되어, 어느 쪽이 더 전경처럼 보이는지를 조사하였다. 그 결과, 여성이 빨간색 원을 더 전경으로 보는 경향이 강했고, 남성은 유의미한 차이를 보이지 않았다. 또한, 이 결과는 단순히 남녀의 색깔 선호 때문이 아니었다. 종합하면, 본 연구의 결과는 비록 직접적은 증거가 될 수는 없지만, 빨강-초록 조합에 대한 남녀의 전경-배경 조직화 처리과정에서 차이가 있을 가능성이 조심스레 제기된다. 여성은 집 근처에서 먹을 것을 수집하고 남성은 집 멀리에서 사냥한다는 수집-사냥 가설(gatherer-hunter hypothesis)을 비롯해 가능한 설명들을 논의 하였다.

  • This study was carried out to investigate a point of difference between normal and inferior Korean red ginseng (Naeback red ginseng = red ginseng with white part of clear boundary in phloem and/or xylem of ginseng body, saengnaeback red ginseng red ginseng with white part of indistinct boundary). White part with clear or indistinct boundary in center of ginseng body was observed in inferior red ginseng (naeback and saengnaeback red ginseng), and the differences in the internal color intensity was also found with naked eye. In hunter color values of normal and inferior parts of red ginseng in accordance with particle size, L value was increased with a diminishment in particle size, while a and b value were decreased. Absorbance at visible spectrum did not differ from water and 70% ethanol extract from normal and inferior parts of red ginseng, but absorbance in UV spectrum of extract from naeback part showed higher than those of normal and saengnaeback part. In comparison of intrastructure by electron microscope, the horizontal and vertical section of cortex and pith layer from normal part showed the very dense state, but small holes were found in naeback part of red ginseng by naked eye and electron microscope. The specific surface area of normal, naeback and saengnaeback part appeared 3.02, 3.33 and 6.55 ㎡/g, respectively. From above results, we consider saengnaeback red ginseng is red ginseng in the intermediate process which normal red ginseng changes to naeback red ginseng.

  • 한국전통색이란 시대를 초월하여 한국민족의 삶속에 살아있는 색이다. 이러한 전통색 중 한국전통색을 대표하는 청·홍의 색조특성을 알아보기 위하여 조선시대의 색명과 염직유물의 색조를 조사하였다. 한국전통색 청·홍의 색조를 조사하기 위해여 먼저 조선시대의 문헌을 통하여 출현색명을 조사하였다. 색조를 나타내는 한국말에는 대단히 다양한 형용사가 앞에 붙어 색조를 특징짓는다. 색명에는 여러유형의 형용사들이 앞에 붙는데, 그 중에 대표적인 것은 농색과 담색을 나타내는 형용사들이다. 이처럼 제한된 색명의 가능성을 증가시키기 위하여 조선인들은 다양한 톤의 청색계(32색)와 홍색계(40개)의 색명을 만들어 내었다. 이러한 청·홍색계의 출현율은 대단히 높고, 조선시대의 궁중복식에서도 주조색으로서 사용되었다. 조선인은 다양한 청·홍색계의 배색으로 그들의 음양론에 기초한 색체관과 세련된 미의식을 표현하였다. 박물관에 있는 염직유물들의 색체는 측색되어 먼셀컬러시스템과 ISCC-NBS의 계통색명법에 의해 분류되고, 고찰되었다. 또한 전통색조인 남염과 홍화염이 산업체에서 이용되어지도록, 남염과 홍화염의 염색방법을 계량화하여, 데이터를 제시하였다.

  • This study was conducted to investigate the effects of dietary supplementation of various types of fermented red ginseng marc with red koji to laying hens on eggshell and egg yolk quality characteristics. A total of 240 Hy-line Brown laying hens (40 wk of age) were randomly allotted to 24 pens (6 replicates per treatment and 10 laying hens per replicate). Experimental diets consisted of 4 treatments containing basal diet (control), 1% fermented red ginseng marc powder with red koji, 1% fermented red ginseng marc pelleted with red koji and 1% fermented red ginseng marc coated with red koji. During the 8-wk feeding trial, there were no significant differences in eggshell strength, eggshell thickness and eggshell color among the treatments, except for eggshell strength at 4 and 8 wk and eggshell thickness at 0 wk. In addition, no differences in egg yolk color and egg yolk index were found for all treatments throughout the 8-wk feeding period, except for egg yolk color at 0 wk. Thus, using various types of fermented red ginseng marc with red koji to laying hens did not improve eggshell and egg yolk quality characteristics.

  • 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.

  • This study examines the unique characteristics of the color red in relation to images used in areas other than fashion, such as the film or advertising industries. Based on analysed results, the aim was to identify red-colored costume's images expressed in contemporary fashion. Analysis of collected data has lead to four main findings. First, the fashion in which the red color is used delivers a voluptuous image when combined with a skinny silhouette or glossy and transparent dress material, arousing a strong sexual desire in a direct or indirect manner when exposing the body in public. Second, the fashion emphasizes a simplified appearance by minimizing the steps of the production process such as cutting, sewing, and decoration without artificial structural lines and creates an image of simplicity through a single red color or tone-in-tone colorations. Third, the red color, which carries a simultaneous negative and pleasure image represents grotesque playfulness by distorting or exaggerating clothes, transforming the body in disregard of clothing construction, or introducing unnatural makeup. Fourth, in combination of simple and clinging shapes, a material feeling tough like leather and an intensely noticeable red tone, promotes the feminine rather than masculine quality in a splendid, aggressive sporty and active "alpha girl" image.
