색은 인간에게 어떤 느낌을 전달하기도 하고 행동에 영향을 미치기도 한다. 특히 적절히 적용된 색은 제품의 품질과 사용성을 향상시키기 때문에 색의 효과에 대한 이해와 신중한 사용이 중요하다. 그러므로 본 연구에서는 온도감에 대한 색의 3요소(색상, 명도, 채도)의 효과와 그 관계를 정확히 이해하고 정보 디스플레이에 적용할 수 있는 응용적 가치를 탐색하고자 하였다. 색상환에 따른 10가지 색상의 온도감은 U 모양으로 나타났는데 빨강에서 가장 높고 파랑과 남색에서 가장 낮았으며, 채도는 색상이 가지는 온도감의 특징을 더 두드러지게 한 반면, 명도의 효과는 없었다. 이 결과는 색의 사용에 제한이 있는 상황에서도 채도의 다른 요소를 조절함으로써 온도감에 변화를 줄 수 있음을 보여준다. 한색과 난색의 구분은 명확하였으며 이러한 색의 주관적 온도감 차이로 인해 참가자들은 그래프 판독에서 실제의 온도보다 더 따뜻하거나 더 차갑다고 보고하는 온도계 측정에서의 판단 왜곡을 보였다. 이런 차이는 과제와 디스플레이 특성에 맞게 색의 구성요소들의 민감도를 조절하는데 적용할 수 있을 것이다.

Polystyrene superstructure films show faint rainbow color, and this low color saturation limits its wide application. In this paper, polystyrene superstructure films with single bright blue color were prepared by vertical deposition self-assembly method using polystyrene microspheres with average diameter of $310{\pm}10nm$ as raw material. Polystyrene superstructure films were modified by adding nano-carbon powder, and effect of the amount of nano-carbon powde on color performance was studied. The results showed that without addition of nano-carbon powder, the superstructure films showed a faint rainbow color, while with addition of nano-carbon power, the superstructure films exhibited a single bright blue under the same natural light source. Changing the amount of nano-carbon powder addition could adjust color saturation of the film. With increasing the amount of nano-carbon powder addition from 0.008 wt% to 0.01 wt%, color saturation of the superstructure film increased gradually. Further increasing the amount of nano-carbon powder addition to 0.011wt%, color saturation of the superstructure film didn't increase anymore and tended to get dark.

This experiment evaluates wintering ability to maintain green color of lawn grasses during winter and investigates the effects of top dressing of fertilizer on improving green color during regrowth. Kentucky blue-grass could maintain green color and leaf chlorophyll content better than tall fescue and creeping bentgrass in winter. All three grasses in this experiment have shown the excellent wintering ability. In enhancing the recovery of green color at the early stage of regrowth, the mulching effect with rice straw was highly significant for creeping bentgrass. Green color recovery in grasses during its regrowth was better at the top dressing plots than at the plots without top dressing, but when fertilizer application levels were increased, green color in lawn grass did not significantly change. Although green color in tall fescue, Kentucky bluegrass, and Korean lawngrass could be maintained during summer, the green color of creeping bentgrass is reduced significantly with high temperature. Top dressing after winter and mowing improved leaf chlorophyll content and green color in tail fescue and Kentucky bluegrass significantly. However, Korean lawngrass did not respond significantly with increased levels of fertilizer.

Purpose. The purpose of this study was to investigate the effect of lens color of sunglasses on stereoacuity by experiment. Methods. We conducted a stereotaxic test using a RANDOM DOT with a polarizing lens at an examination distance of 40 cm in 100 men and women aged 20 to 60 years without any specific ocular disease. Then, seven kinds of PVC color film such as yellow, black, brown, red, purple, blue and green were put on the polarizing lens and the stereoscopic examination was carried out again. Results. When the lens color of the sunglasses is yellow, black, and brown, it affects less stereoscopic effect. However, red, purple, blue, and green have much influence on stereoscopic effect. Especially, the red and purple colors affected the stereoscopic vision. In blue and green, the effect of stereoscopic vision was different according to the people. Conclusions. Depending on the lens color of the sunglasses, stereoscopic vision is affected, which can cause problems in binocular vision. Therefore, when choosing sunglass lens color, many buyers need to pay attention.

The purposes of this study were to investigate the Maillard reactions of some oligosaccharides with lysine and the antioxidative effects of the ethanol extracts from their reaction mixtures on the soybean oil. The Maillard reactions were carried out of 2% oligosaccharides such as palatinose (PN), fructooligosaccharide (FO), isomaltooligosaccharide (IMO) with 2% lysine (L) for 24 hours heating at 60, 80, $100^{\circ}C$. The color intensity of Maillard reaction mixtures were determined by UV-VIS spectrophotometer upon reaction time and temperature. And the antioxidative effects on the soybean oil of each ethanol extract from Maillard reaction mixture of each oligosaccharide were measured by peroxide value (POV). POV's of soybean oil including reaction extracts were determined regularly every 2 days during 20 days storaged at $60{\pm}1^{\circ}C$. The results were obtained as follows: 1. The color intensity of the Maillard reaction mixtures were raised highly as the browning temperature and time increased. The color intensity of PN L browning mixture was the highest. The order of high color intensity at $100^{\circ}C$ was PN L>FO L>Glu L>IMO L. 2. Comparing the antioxidative effect of Maillard reaction product (at $100^{\circ}C$, for 12 hours) of each oligosaccharide to that of BHT and TBHQ, the order of high antioxidative effect was TBHQ>IMO L>BHT>Glu L>PN L>FO L. 3. From these results, it was known that PN L shown as high brown color intensity was appeared low antioxidative effect, while IMO L shown as low brown color intensity was appeared high antioxidative effect. So, it was recognized that there was no relation between brown color intensity and antioxidative effect.

An experiment was conducted to evaluate the effect of different levels of extracted pigment from Dietzia natronolimnaea biomass as a source of canthaxanthin in comparison with synthetic canthaxanthin on egg yolk pigmentation. The experiment used a completely randomized design (CRD). A total of 63 laying hens, 68 weeks old, were used and the birds were allotted to 7 dietary treatments with each treatment replicated three times with three hens per replicate. Treatments consisted of 3 levels of synthetic canthaxanthin (4, 8 and 16 ppm), 3 levels of extracted pigment from D. natronolimnaea biomass (4, 8 and 16 ppm) and control. Changes in yolk color were determined in 2 eggs taken at random, during the four week experimental period from each replicate. Supplementation of extracted pigment from D. natronolimnaea biomass had a significant effect on the color of egg yolks (p<0.05). Yolk color score of the control group was 6.83 in BASF color fan and the yolk color score of different extracted pigment levels was 11.00, 12.50 and 14.50, respectively. The yolk colors of different levels of synthetic canthaxanthin were 12.00, 14.00 and 15.00, respectively. The effect of pigment supplementation on egg yolk color was better explained by polynomial response curves. The $R_{2}$ indicated that for 3 supplementation levels of each pigment studied, over 90% of the color variation could be explained by the pigment concentration. The egg yolk color after 15 and 30 days of storage was not significantly different, but boiling reduced egg yolk color significantly (p<0.05).

Purpose: The purpose of this study is to find out whether the color change of the LED light source has a significant effect on the beta wave activity of EEG in the learning state. Methods: The subjects of the experiment were 20 male and female college students between the ages of 19 and 25 who routinely perform their studies. In the created learning environment, the EEG change according to the change in the lighting color was measured while solving the Mensa thinking ability problem while sitting on a desk with LED lights installed on the top and a chair with a footrest to stabilize the legs. The light source consisted of 3 ready-made colors and 6 newly created colors. A total of 9 color light stimuli were given for 2 minutes each, and the EEG change of the subject was observed. After the experiment, the correlation was analyzed based on the mid-beta wave data recorded on the QEEG according to the color change of light and the Mensa problem score. Results: It was found that the activation of mid-beta waves was stimulated in the temporal lobes (T5, T3, T6, T4) and occipital lobes (O1, O2) of all subjects who focused on solving Mensa thinking problems. As a result of comparing the top 20% and the bottom 20% of problem solving scores, the upper group had no effect of lighting, while the lower group showed increased beta wave activity in response to color light stimulation in the order of T4, T6, and T5. Implications: It was confirmed that the color of light that activates the middle beta wave varies greatly depending on the subject's attention and learning ability, and it is judged that the color of light including the green wavelength is helpful in activating the middle beta wave in the group with low learning ability.

The residential and welfare facilities for the elderly are continuously increasing due to change of value on family under situation of aging population increase. And it is predicted that accommodation capacity of facilities for the elderly and its rate those facilities takes compared to whole social welfare facilities will be accelerated considering past increase speed. On the other hand, about 60% of the elderly have low physical and mental level almost close to disabled people therefore special environmental concerns helping their independent living are necessary. Among them, color application is one of the most important factors for smooth understanding, communication and psychological remedy effect for them. The purpose of this study is to analyze the interior color status in assisted living facilities for the elderly in America which is a leading country in terms of the understanding and policy for the elderly as a part of the research project to suggest the developed solution about the Korean residential welfare facilities for the elderly For this purpose, not only importance and effect of color and visual characteristics and reaction to color in elderly environment but also general concept and policy of the ‘assisted living facility’ in America were researched through documents review. And measuring of color on 5 main spaces such ; lobby/lounge, corridor, dining room, bedroom, stairway/ramp of the 10 facilities in America were performed under analysis of its functional and aesthetic level based on Moon & Spencer's color theory.
