Soybean sprouts have good digestibility, high isoflavone content compared with soybean seeds, and large amounts of aspartic acid, which is effective in eliminating hangovers. However, the region between the cotyledon and hypocotyl in soybean sprouts appears purple, the product value of soybean sprouts reduces. To date, the scientific correlation among factors such as growth temperature, spray water temperature, and cultivation periods for soybean varieties related to purple color expression between the cotyledon and hypocotyl of soybean sprouts are unknown. The purpose of this study was to identify the factors regulating the expression of purple color between the cotyledon and hypocotyl of soybean sprouts. Of 15 Korean soybean varieties with purple color in the hypocotyls and flowers, 9 varieties, including Sowonkong, Wonhwang, Sinhwa, Eunhakong, Pungsannamulkong, Paldonamulkong, Kwangankong, Shingang, and Jangki showed purple color between the cotyledon and hypocotyl of sprouts. However, the remaining six cultivars, including Dachae, Myeongjunamulkong, Sobaeknamulkong, Sojinnamulkong, Anpyeong, and Jonam, did not show purple color. The proportion of soybean sprouts with purple hypocotyls was the lowest at $26^{\circ}C$ and there was no significant difference at the other three cultivation temperature conditions ($17^{\circ}C$, $20^{\circ}C$, and $23^{\circ}C$). Similar to the results of the cultivation temperature experiment at five different spray water temperatures ($10^{\circ}C$, $17^{\circ}C$, $20^{\circ}C$, $23^{\circ}C$, and $26^{\circ}C$), the proportion of soybean sprouts with purple hypocotyls was the highest at the lowest spray water temperature ($10^{\circ}C$), and lowest at the highest temperature. Additionally, there was no purple color expression in soybean sprout hypocotyls on the $3^{rd}$ day after soybean sprouting. However, the highest expression level was observed on the $4^{th}$ day. Then, on the $5^{th}$ day, the proportion of soybean sprouts with purple hypocotyls reduced significantly, compared with that on the $4^{th}$ day. The results showed that interaction among these factors under cultivation conditions was remarkably effective for the expression of purple color in hypocotyls under the dark condition. These results suggested that cultivation temperature and spray water temperature for purple color expression in soybean sprout hypocotyls are the most important factors in the sprout cultivation environment.

Loess, a natural clay, was evaluated as an adsorbent for the decolorization of Acid Orange II, an azo and reactive dye, from aqueous solution. Adsorption studies were performed at $30^{\circ}C$ and the effect of reaction time, loess dosage, initial concentration, loess particle size, pH, agitation rate were investigated to determine the optimum operation conditions. The removal efficiencies of color were measured to evaluate the effectiveness of loess. From this study, it was found that optimal reaction time was 10 min. Color removal efficiencies of Acid Orange II were increased as higher loess dosage, initial concentration and agitation rate. However, color removal efficiencies decreased when pH is high and loess particle becomes large. Adsorption of Acid Orange II fitted to the pseudo-second-order rate kinetics more than first-order rate kinetics. Langmuir and Freundlich adsorption isotherm constants and correlation coefficients were calculated and compared. It was concluded that the adsorption data of Acid Orange II onto loess fitted to the Freundlich model more than Langmuir model.

The luminescence and fluorescence were investigated by photoluminescence spectroscopy for six gemstones which exhibit color change effect. The shape of luminescence peaks appears different when observed by a photoluminescence spectroscopewith a 514 nm Ar laser source. However, it was not possible to observe the difference in the spectra between the natural and synthetic origins for the same type of gemstones. It was found that the photoluminescence spectrum was related to the crystal structure of the stones. Photoluminescence spectra using a 325 nm He-Cd source reveal that fluorescence is relatively strong for synthetic alexandrite, synthetic color change sapphire and natural alexandrite comparing to the rest of gemstones examined.

Model-based color image halftoning method using dot-pattern database is proposed for low-resolution color image printing. Dot-pattern database used in the proposed method is based on Blue-Noise Mask. The database consists of dot-patterns constructed by circular dot-overlap model according to each color value. In halftoning procedure, input color value is reproduced as the dot-pattern selected to minimize the difference between the color values of the original image and those of the printed image. Also, the contrast sensitivity function as a human visual model is used to improve the perceived quality of the printed image in dot-pattern selection. Thus, the proposed method can substantially reproduce the color values of the pixels in original image and obtain better image quality. In the experiment, the proposed method has less ΔΕ/Sub ab/ between the original image in monitor and the printed one than that of ED and BNM halftoning. This result approves that the proposed method reproduces better image quality.

Records from a total of 202 crossbred pigs were classified by their ear type and coat color to examine the presence of interrelationships with growth performances. Crossbred pigs were F2 generations of full sib family out of ten Landrace sows bred by 5 Korean domestic boars. Heavily drooped ear type was predominant, 195 out of 202 pigs over the other two types (1 straight and 6 slightly drooped). Coat colors were classified as four categories, all white, all black, dominant white or dominant black. Ratio among coat color categories did not fall within Mendelian principle of independence regarding two loci involved. There was dependency between ear type and coat color. However, due to rarity of ear types other than heavy drooped, dependency comes from distribution of those rare ear types. Three least squares models to test the effect of ear type and coat colors on growth performances were analyzed. First model analyzed effects on birth weight, body weight at 3 and 6 weeks and ADG' before weaning and between 3 and 5 weeks of age. This model included sex in addition to ear type and coat color. Second model analyzed postweaning growth traits (initial weight, final weight and ADG between these periods) upon initiation of performance testing. This model included effects of sex, test group and start age (as a covariate) in addition. Third model was fit for fasted weight before slaughter and included the effects of sex, test group and age at slaughter (as a covariate). The effects of sex and ear type were not significant source of variation for all traits. Test group was a significant source of variation for all the postweaning traits. Effect of coat color was not significant until the initiation of performance testing and became significant then after. Least squares means of dominantly black pigs were significantly lower than the other three coat colored pigs in final weight around 195 days of age and in ADG from the start of performance test and final weight measure.

Offset lithography is the most widely used printing process in domestic printing industry, but there are no industry-wide specifications for press control to assure consistent quality across printing plants. As printing becomes more of a commodity and less of an art, it is necessary to develop a print quality specification standard suitable for Korea offset printing field. This study aims to contribute to improving the quality of domestic offset color prints by comparative study on color reproduction properties of 2 kinds of domestic process color ink composed of C(cyan), M(magenta), Y(yellow) and K(black) and of 3 kinds of domestic coated paper, using colorimetric color measurement method.
