This study was performed in order to suggest useful data for color planning of eco-friendly and sensible fashion products. Silk fabrics were dyed in combination with natural indigo and Japanese pagoda tree and were treated with four kinds of mordants after combination dyeing. Then, their colorimetric properties were evaluated. From these composite-dyed silk fabrics, color sensibilities and color preferences of green yellow (GY) color were evaluated among the female university students, and thus, the influences of colorimetric properties and color sensibilities on color preferences were analyzed. When the silk fabrics were dyed in the combination of natural indigo and Japanese pagoda tree and were treated without mordants, they turned green color when indigo 10 g/L was used, and blue-green when indigo 20 g/L was added. And when they were dyed in combination of natural indigo and Japanese pagoda tree and were treated with four kind of mordants after combination dyeing, they turned GY color in almost all cases. The color sensibilities of the GY silk fabrics with the combination dyeing of indigo and Japanese pagoda tree, were classified into three factors: pleasantness, gracefulness, and comfort. Color sensibility factors showed significant differences according to the concentration of indigo and the kinds of mordants. There were almost significant relationships between colorimetric properties and color sensibilities factors of compositely dyed GY silk fabrics. The color preferences of the GY fabrics, which were dyed in the combination of using natural indigo and Japanese pagoda tree and four kinds of mordants, were found to be predicted by the color sensibility in a regression model.

In the present study, the seed color of 200 common bean genetic resources was analyzed and located on the HTML color chart to classify these resources according to color characteristics. This classification method predicts the components of seed and may serve as a new method for efficiently using secured genetic resources. The imagary data of common bean exhibiting various seed colors were expressed using the HTML color chart. According to the proposed classification method, the seed color was distributed in seven categories: yellow-green, yellow, brown, red, white, gray, and indigo. In addition, the distribution of each seed color was according to its concentration. The distribution by concentration was the highest for red, whereas the distribution of gray and yellow-green was not concentration-dependent. As the dominant pigments based on color distribution, chlorophylls in yellow-green; carotenoids in yellow; and anthocyanins in brown, red, white, gray, and indigo significantly affected seed color. When expressed objectively, seed colors can be applied to the systematic management, breeding, and cultivation of genetic resources and can be useful for marketing or developing products of desired colors. This method can also be applied to other crops.

Hosta 'Yellow Tiara' was induced using methyle methane sulfonate (MMS) to obtain mutagens. Among the induced leaf-variegated hosta plants, some with yellow-green leaves were selected. They were cultivated via vegetative propagation. Assessment of the botanical characteristics was conducted for three years since 2004. The major characteristic of these cultivars is that they maintain their yellow-green leaves uniformly all year round. These cultivars are useful as materials for pot plants or as ground cover.

To develop tofu enhanced nutrition, storage stability and bioactivity, the soft tofu supplemented with red ginseng extract was prepared. Then, quality characteristics including storage stability, physical and chemical property, antioxidative activity, and sensory evaluation were measured. The pH and acidity of control tofu without red ginseng extract were not different from those of tofu supplemented with red ginseng extract during storage. The aerobic bacteria in the control tofu were detected from 10 days of storage whereas the number of total aerobic bacteria was reduced or not detected in the tofu added red ginseng extract during storage. The lightness and redness of the tofu supplemented with red ginseng extract were lower than those of control, but yellowness was higher. The addition of red ginseng extract did not also affect the texture of tofu, and increased lipid peroxidation inhibition and DPPH radical scavenging activity. Although the soft tofu manufactured with red ginseng extract showed a lower sensory preference in supplementation over 0.20% due to color, there was not much difference found until 0.18% red ginseng extract addition.

Pseudoips fagana Fabricius belongs to the subfamily Chloephorinae (Lepidoptera: Noctuidae). Eggs of Pseudoips fagana were white and oviposited on oak leaves. There were five P. fagana larval instars, which were light green in color with four white crosslines. The larval period was approx. 24.4 days ($25^{\circ}C$, 16L:8D). Pupae were covered with a light-green membrane and silk. The wingspan of adults was approx. 15 to 18 mm. The color of the forewings of both sexes was bright green. The color of the hindwings was yellow in males and and white in females. First emergence was from early May to late June, and the second emergence was from early July to late August. Pseudoips fagana over-wintered as pupae.

For the detection of contaminated liquid spawn, we selected suitable medium, indicator and developed method of diagnosis. The growth of pathogenic bacteria, Pseudomonas sp., and fungi, Trichoderma sp., in YPL media was better than in PDA and NA. In addition, the changes of color and absorbance of media were obviously showed when contaminated liquid spawn by pathogenic bacteria and fungi was incubated on YPL including phenol red for 48 hour at $25^{\circ}C$. The color of YPLP after incubating of infected liquid spawn by Pseudomonas sp. and Trichoderma sp. were changed from orange to red and to scarlet, respectively. Whereas, the color of YPLP after incubation of only Pleurotus ostreatus indicated yellow at liquid spawn. Therefore, it is possible to easily distinguish contaminated liquid spawn by color of change in YPLP.

This study examined whether the combination of the indoor temperature on the learning environment and the colors of the learning materials affect the learning performance. To do this, the condition of indoor temperature was divided into three conditions: the neutral condition which is the appropriate temperature condition of the learning activities ($22.5{\sim}24^{\circ}C$), the high-temperature condition (> $24^{\circ}C$), and the low-temperature condition (< $22.5^{\circ}C$). In addition, colors of red, blue, black, and green were used as the warm, cold, and neutral colors, and the verbal-working memory task was used as the learning task. As a result, it was not significant differences in the response time of the learning task, whereas, in the accuracy rate of the learning task, the performance was more accurate in red- and black-color conditions. These results could be interpreted as the saliency and color-temperature of the red color, and the familiarity and specificity of the black color.

상대적으로 산출양이 많은 보석용 천연 갈색 다이아몬드는 고온고압 공정을 통해서 칼라센터를 제어하여 색향상이 가능하다. 질소가 불순물로 함유된 Type IaA 다이아몬드를 5.6GPa-30min 조건으로 압력과 처리시간을 고정하고, 이때 처리온도를 1600, 1650, 1750, $1800^{\circ}C$로 바꾸어 HPHT 처리하였다. 처리조건에 따른 다이아몬드의 물성변화 확인을 위해서 광학현미경, FTIR, 저온 PL, Micro-Raman 분석을 진행하였다. 광학현미경 확대 이미지를 통해서, $1600^{\circ}C$에서도 색향상이 가능하였으며 온도증가에 따라 색향상은 진한노랑(vivid yellow)에서 연두 노랑색(vivid greenish yellow)로 색이 변하는 경향이 있었다. 또한 $1750^{\circ}C$의 고온에서는 탄소점으로 추정되는 결함이 확인되었다. FTIR 분석결과에 의해 HPHT 처리 후에도 다이아몬드의 Type IaA로 유지됨을 알 수 있었다. 저온 PL 스펙트럼결과 처리 후 모든 시편에서 H4센터는 소멸하지만 H3 센터는 잔류함을 확인하였다. 따라서 HPHT 처리온도를 조절하여 목표하는 색으로의 향상이 가능하였고, 되도록이면 탄소점과 같은 결함을 방지할 수 있는 저온 HPHT 처리가 유리하였다.
