유통기간중의 환경조건은 숙주나물의 상품성에 영향을 미친다. 본 연구는 유통과정중 필연적으로 부딪히는 빛이 숙주나물의 상품성에 미치는 영향을 추적하여 판매용 소봉지 도안에 필요한 정보를 제공하고자 광질(청색, 녹색, 황색, 적색 및 초적색) 처리가 $8^{\circ}C$에 저장중인 숙주나물의 녹화 시간, 저장 5일후까지 매일 형태와 무게에 미치는 영향을 조사한 결과를 요약하면 다음과 같다. 1. 숙주나물의 녹화에는 $2.5{\sim}3.5$일이 소요된 청색광, 적색광과 초적색광에 비하여 6일 이상 소요된 녹색광과 황색광 처리에서 상대적으로 길었다. 2. 발생된 개체당 세근수는 광질 처리간 차이가 없었으나 전체 길이는 황색광 처리에서, 하배축 직경은 청색광 처리에서 가장 길고 굵은 것으로 조사되었다. 3. 개체당 전체 생체중과 건물중은 적색광 처리에서 가장 많았던 반면, 초적색광 처리에서 가장 적었다. 4. 녹화에 걸리는 시간이 가장 길었던 녹색과 황색 모두 저장기간이 길어질수록 숙주나물의 길이, 직경과 무게가 감소되었으나 그 영향은 유사한 것으로 나타났다. 5. 이상의 결과로부터 숙주나물의 판매용 소봉지는 형태와 무게의 변화보다는 녹화로 인한 상품성 손실이 크기 때문에 주로 녹색과 황색으로 도안이 이루어져야 한다.

Bulb color in onions (Allium cepa) is an important trait whose complex inheritance mechanism involves epistatic interactions among major color-related loci. Recent studies revealed that inactivation of dihydroflavonol 4-reductase (DFR) in the anthocyanin synthesis pathway was responsible for the color differences between yellow and red onions, and two recessive alleles of the anthocyanidin synthase (ANS) gene were responsible for a pink bulb color. Based on mutations in the recessive alleles of these two genes, PCR-based markers for allelic selection were developed. In this study, genotype analysis of onions from segregating populations was carried out using these PCR-based markers. Segregating populations were derived from the cross between yellow and red onions. Five yellow and thirteen pink bulbs from one segregating breeding line were genotyped for the two genes. Four pink bulbs were heterozygous for the DFR gene, which explains the continuous segregation of yellow and pink colors in this line. Most pink onions were homozygous recessive for the ANS gene, except for two heterozygotes. This finding indicated that the homozygous recessive ANS gene was primarily responsible for the pink color in this line. The two pink onions, heterozygous for the ANS gene, were also heterozygous for the DFR gene, which indicated that the pink color was produced by incomplete dominance of a red color gene over that of yellow. One pink line and six other segregating breeding lines were also analyzed. The genotyping results matched perfectly with phenotypic color segregation.

The purpose of this study was to identify the change of perception and preference of color according to time passage. The subjects were university students and for the survey 257 questionnaires in 1998 and 522 questionnaires in 2005 were effectively used to compare the perception and preference of color between the both period. The statistics was performed with frequency analysis and independent t-test in SPSS 10.0. The results were as follows. 1) Color perception according to time passage showed significant differences in red, yellow, green, and blue color. 2) Color preference according to time passage showed significant differences in red, green, and blue color. 3) Color perception among three regions according to time passage showed significant differences in red color in Seoul, yellow color in Seoul, Mokpo and Jeju, green color in Seoul and Mokpo, blue color in Seoul, Mokpo and Jeju, and purple color in Seoul. 4) Color preference among three regions according to time passage showed significant differences in yellow color in Mokpo, green and blue color in Seoul, Mokpo and Jeju.

An experiment was carried out to study the effect of environmental color on the eating behaviour in broiler chicks. A total of ninety broilers with average 350g of initial body weight were randomly assigned in the $3{\times}3$ randomized complete block design with 3 treatments(yellow, blue, red) and 10 birds per replication of various environmental color at walls, feeders and electric bulbs. The results obtained from these experiments are summarised as follows: 1. Feed Intake and average daily gain were significantly(P<0.05) increased by yellow colored environment. 2. Eating time and eating rate were significantly higher in the red colored than the other, indicating that yellow colored environment would maximize body weight gain and feed conversion for broiler chicks.

Characteristics of fecal sites of the Siberian flying squirrel Pteromys volans was analyzed based on 132 sites of total 19 places. The fecal sites were more frequently found in winter (43.9%), and then followed by autumn (27.3%), spring (23.5%), and summer (5.3%). With the exception of summer, the fecal sites were more frequently found at the root collar than on the forked tree (p<0.01). Among 132 fecal sites, 88 sites (66.7%) were found on the rood collars and the other 44 sites (33.3%) were posited in the forked trees. Brown or red clay pellets were found at 44 fecal sites (33.4%) and 43 fecal sites (32.6%), and then black and yellow pellets were at 22 fecal sites (16.7%) and 19 fecal sites (14.3%), respectively. Green pellets were rarely found only at 4 sites (3.0%). Feces tend to have bright colors (brown, red clay and yellow) in winter and black in summer. Fecal sites with yellow pellets were much less found in all of the three seasons with the exception of winter, but highly increased in 25.4% in winter. The fecal sites with brown (33.4%) and red clay pellets (32.6%) were most frequently found through the four seasons.

Due to optimal advances such as chromatic performance, durability, low power consumption, high efficiency, long-lifetime, and excellent environmental friendliness, white LEDs (WLEDs) are widely used in vehicle front lighting, backlighting, decorative lighting, street lighting, and even general lighting. In this paper, the remote packaging WLEDs (RP-WLEDs) with bi-layer red-emitting $Sr_2Si_5N_8:Eu^{2+}$ and yellow-emitting YAG:Ce phosphor was proposed and investigated. The simulation results based on the MATLAB software and the commercial software Light Tools indicated that the color rendering index (CRI) of bi-layer phosphor RP-WLEDs had a significant increase. The CRI had a considerable increase from 72 to 94. In conclusion, the results showed that bi-layer red-emitting $Sr_2Si_5N_8:Eu^{2+}$ and yellow-emitting YAG:Ce phosphor could be a prospective approach for manufacturing RP-WLEDs with enhanced optical properties.

The four azo dyes such as Amaranth (FD & C Red No. 2), Tartrazine (FD & C Yellow No. 4), sunset Yellow (FD & C Yellow No. 5) and Allura red (FD & C Red No. 40) are currently employed as a food additives in Korea. In this study, the effects of these azo dyes on the hepatic microsomal mixed function oxidase systems in Rats. (i.e., Cyt. P-450, Cyt. b$_5$, NADPH cyt. c-reductase and azo reductase) were investigated. Furthermore, to determine the relationship among the electron transport systems, each level of azo reductase, Cyt. P-450 and NADPH cyt. c-reductase was measured upon the administration of phenobarbital (known as an inducer of Cyt. P-450), 3-methylcholanthrene (Known as an inducer of Cyt. P-448), CoCl$_2$ (inhibitor on Cyt. P-450) or $CCl_4$ (inhibitor on Cyt. P-450). The results of these studies are as follows; (1) The levels of Cyt. P-450 and Cyt. b$_5$ were decreased upon the administration of these azo dyes. (2) When the level of Cyt. P-450 was decreased, the azo reductase activity was also decreased. (3) These azo dyes did not show any significant effect on the level of NADPH cyt. c-reductase. (4) The administration of 3-methylcholanthrene resulted in the elevation of azo reductase activity. The 3-methylcholanthrene may be responsible for the induction of CO-insensitive electron transport system.
