  • The author carried out an experiment to find out the response of Striped puffer. Fugu xanthoperus (Temminck et Schlegel) to the color lights. The experimental tank (300L$\times$50W$\times$50Hcm) was set up in a dark room. Six longitudinal sections with 60cm intervals are marked in the tank to observe the location of the fish. Water depth in the tank was kept 50cm level. Light bulbs of 20W at the both ends of the tank projected the light horizontally into the tank. Two different colored filters were selected from four colors of red, blue, yellow, and white, and the were placed in front of the light bulbs to make different colors of light. Light intensity was controlled by use of auxiliary filiters intercepted between the bulb and the filter. The fishes were acclimatized in the dark for 60 minutes before they were employed in the experiment. Upon turning on the light, the number of fish in each section was counted 40 times in 30 second intervals, and the mean of the number of fish in each section was counted 40 times in 30 second intervals, and the mean of the number of fish in each section was given as the gathering rate of the fish. The colors favourited by the fish was found in order of blue, yellow, white and red in the daytime, and blue, white, yellow and red at night. The difference of the average distribution on two different colors of light was 13.12%(4.10-26.55%), and the difference in the daytime(14.79%) was larger than at night (11.45%). Constantly the gathering rate of fish on illumination period was fluctuated with instability. As the gathering rate of fish on illumination period was fluctuated with instability. As the gathering rate on one color of light increased, the gathering rate on the other color of light decreased. The difference of the gathering rate on two different colors of light was comparatively distinct and the difference in the daytime was larger than at night.

  • The purpose of this study was to seek the means of enlarging the application of Saek-dong to fashion products by surveying and analysing the recognition and image of Saek-dong in college students. As a research procedure, the bibliographical survey on the meaning and history of Saek-dong was preceded in this study, and the students were examined on the recognition and image of Saek-dong through the questionnaires. The female students were more acquiesced with the Saek-dong and Saek-dong clothing than the male students. And the students thought that the Saek-dong was our original and traditional clothing because it was worn by our ancestors from the earliest years. The word Saek-dong reminded them of red, yellow, blue, green, white and red-brown colors in order of appearance. The most familiar color-arrange to them was red+yellow+dark-brown+green+blue, and the blue, purple, green, red, white color was thought as manly Saek-dong colors and the yellow, red, dark-brown, pink, white was regarded as feminine Saek-dong colors. Saek-dong was primarily associated with the image of Saek-dong clothing and most of the students expressed their feeling about the Saek-dong as 'cute.' Most of the students responded that the practical Hanbok was best illustrated as the most applied clothing of Saek-dong and that the attempt to apply the color and pattern of Saek-dong to other modern artistic products was likely to damage the worth of traditional Saek-dong. When it comes to the matter of applying the design of Saek-dong to the fashion products, male students thought that it could be best applied to the shirts, while female students thought that the design of Saek-dong could best be applied to the personal ornaments.

  • Two strains, each of Tremella fuciformis and Hypoxylon sp. were isolated and their mycelial properties were investigated. T. fuciformis produced yeast-like conidia and dikaryotic mycelia from white to yellow color. The diameter of the hyphae was $1.5\;to\;3.0\;{\mu}m$, and septa with clamp connections were present. Secondary mycelia with clamp connections could produce fruitbodies on sawdust medium when the environmental conditions were suitable for fructification. The symbiotic fungus, Hypoxylon sp. produced white feather-like mycelia. But the color of old mycelia was changed to light yellow or light brown and pigmented the culture medium from light brown to brown or very dark green. Generally it did not produce conidia, but in a special case it produced conidia of which color was yellow green to grass green and of which shape was sub-elliptical with the size of approximately $3\;to\;5\;{\mu}m$.

  • Modern Hanbok tends to use new colors based on traditional colors and their symbolic meanings. In addition to the traditional colors, various expressions have been increased, it is necessary to consider the color and color trend used in modern clothing. This study focused on the period 2011 - 2020 and analyzed the main color and coloring method of top and skirt by year with 450 data from a total of 81 wedding magazines. The results of examining the characteristics of traditional colors during the target period are as follows. First, the main color of the Jeogori showed a distribution of various colors in the first half, but the main color of the skirt concentrated on black, white and light pink in the second half. Second, while the use of blue and green systems decreased, Dang-ui color changed to warm yellow, green, and red systems. The Baeja used plain dark white in the first half; however in the latter half, they changed to white or accented colors. The one-piece used various colors in the first half, but only black and white appeared in the second half. Third, in the upper and lower colors of Hanbok, the blue-red color, the traditional contrast color of the first half, decreased significantly in the second half. The appearance rate of proximity for the complementary color harmony of white-red color and the adjacent color harmony of white-blue increased.

  • This study was conducted to investigate effects of dietary pigment sources on shell color of juvenile abalone, Haliotis discus hannai. Three replicate groups of the abalone, average weight 173 mg, were fed the diets containing various pigment sources such as Porphyra powder, Spirulina, yeast astaxanthin and paprika extract for 16 weeks. Survival and weight gain were not affected by dietary pigment sources (P>0.05). Shell color of abalone fed diets containing Porphyra powder and Spirulina was approached to yellow-red and orange which are similar to shell color of wild abalone. However, shell color of abalone fed the diets containing yeast astaxanthin and paprika extract were similar to that of control diet showing bright green. Porphyra powder and Spirulina contain not only fat-soluble pigment such as chlorophyll and carotenoids but also water-soluble pigment such as phycoerythrin and phycocyanin. These results would be useful information to change shell color of abalone in aquaculture.

  • A color halftoning is the process of generating halftone images for the different color plans, for example, cyan, magenta, yellow, and black for a offset printing device. A conventional halftone technique, so called AM screening, is simple and easy to implement, but the halftoned dot patterns by using this method is not free for the moire` fringe. Moire` patterns are caused the power spectrum distribution on low spatial frequency domain. To avoid Moire` patterns, the conventional screen require the different screen angles for each color plans. Recently, Ultra-fine and 7 color printing methods are developed to expend the color gamut. In 7 color printing method must be used the halftone technique of random and blue noise characteristic to avoid Moire` fringe.

  • This paper proposes an RGB to RGBY color conversion algorithm for liquid crystal display (LCD) using RGW pixel structure with two-field (yellow and blue) sequential driving method. The proposed algorithm preserves the hue and saturation of the original color by maintaining the RGB ratio, and it increases the luminance. The performance of the proposed RGBY conversion algorithm is verified using the MATLAB simulation with 24 images of Kodak lossless true color image suite. The simulation results of average color difference CIEDE2000 (${\delta}E^*_{00}$) and scaling factor are 0.99 and 1.89, respectively. These results indicate that the average brightness is increased 1.89 times compared to LCD using conventional RGB pixel structure, without increasing the power consumption and degrading the image quality.
