The purpose of this study was to comparatively analyze the characteristics of traditional costume colors of Korea China Japan with quantitative methods. The range of this study was limited to the costume colors from 16th to 19th century. For this study 1333 color samples were collected by measuring with a spectrophotometer. The results of this study are as follows: Red, Yellow Red, Yellow and Purple Blue had been used in common for the traditional costume colors of Korea, China and Japan. Yellow of Korea, Purple Blue of China, Yellow Red of Japan showed the high frequency. Red, an asian preference color, had most frequently used in korean traditional costumes. Pale toned Yellow and Yellow Red, high saturated Red and low valued Purple Blue had been preferred for korean traditional costumes. The preferences of high saturated Red and low valued Purple Blue were based on the Five Element theory and the pale toned Yellow and Yellow Red were used with the preference of White and natural colors. In China the traditional costume colors had used with the Five Element theory also but they had preferred Purple Blue, deep & strong toned Red to Yellow Red and Yellow, Yellow Red, Purple and grayish colors had been frequently used in japanese traditional costumes. In the results of color distributions in $L^*a^*b^*$ color space, korean and chinese traditional costumes colors concentrated in some areas like Yellow, Yellow Red, Red and Purple Blue. Japanese costumes colors showed the even distribution with the diverse toned colors. Korean traditional costume colors corresponded with the Five Element theory rather than China and Japan. Japan had used the costume colors with the racial sensibility rather than conceptual color theory.

Fatty acid (FA) composition of longissimus dorsi intramuscular fat in Black Yak and Chinese Yellow Cattle were evaluated in 44 Black Yak and 41 Chinese Yellow Cattle of both genders. Interactions of species with gender were observed for total saturated fatty acid (SFA), unsaturated fatty acid (UFA), monounsaturated fatty acid (MUFA), polyunsaturated fatty acid (PUFA), palmitic acid, stearic acid, oleic acid, linolenic acid, arachidonic acid, EPA, and DHA concentrations, as well as PUFA/SFA ratio in the longissimus dorsi (p<0.05). The SFA percentage was greater in yellow cattle than yak in both genders but the species difference in heifers was greater than in steers (p<0.05). Yak had greater UFA, MUFA and PUFA percentages than yellow cattle in both steers and heifers (p<0.05) but the difference between yak and yellow cattle heifers was greater than yak and yellow cattle steers. The percentages of inolenic acid, arachidonic acid, eicosapentaenoic acid, and docosahexaenoic acid; and PUFA/SFA were greater in yak than yellow cattle in both steers and heifers (p<0.05). In addition, the ratio of n-6/n-3 PUFA in yak was lesser than in yellow cattle (p<0.05). These results indicated that FA composition generally differed between yak and yellow cattle but the differences were not the same in heifers as compared to steers. Results also suggested that species differences in FA composition tended to favor Black Yak over Chinese Yellow Cattle, indicating that the longissimus dorsi of Black Yak may have a higher nutritive value than that of Chinese Yellow Cattle and potential for development as a desirable natural product.

Antimicrobial activity of yellow pigment produced by Monascus anka Y7 (Y7) was studied. The crude yellow pigment of Y7 showed antimicrobial activity against some bacteria and yeasts. The diameter of inhibition zone against gram-positive bacteria was a little smaller t]fan that of gram-negative bacteria to the crude yellow pigment. Especially, E2 fraction obtained from the crude yellow pigment by TLC method showed high anti-microbial activity against E. coli.. The fraction had bright yellow pigment, showing fluorescent light and having the maximum absorption at 373 nm. Citrinin, a mycotoxin which had been characterized as an antimicrobial substance from a Monascus strain, was not detected in the E2 fraction and in the crude yellow pigment by the results of TLC and HPLC. This indicates that the antimicrobial activity of Y7 pigments did not any relationship with citrinin. Yellow degree (b/a of Hunters color value) of Y7 pigment was much higher than that of other natural colorants such as annatto, gardenia yellow and carthamus yellow. But the colors of all of the yellow pigments were similar by panels. Thus, the yellow pigment of Y7 could be used as a useful alternative colorant for food industry, having the advantage of antimicrobial activity.

Macroscopic and microscopic characteristics of Yellow-hearted pine and Red pine were investigated. Wood color, annual ring width and latewood percentage were observed by the naked eye. Anatomical properties as the structure of three sections and cell dimensions were examined by an optical microscopy. As a result, the color of bark in Yellow-hearted pine was Reddish-grey, and Red pine showed brown or gray. The color of heartwood and sapwood in Yellow-hearted pine was deep-yellow to brown and creamy-white. And the color of heartwood and sapwood in Red pine was light-brown and light-yellow. The annual ring width of Yellow-hearted pine was narrower than that of Red pine, and the latewood percentage of Yellow-hearted pine was a little higher than that of Red pine. There was no significant difference in the anatomical characteristics between Yellow-hearted pine and Red pine.

Yellow poplar is well known commercial hardwood species in the world because of its availability, rapid growth, large size, excellent form, early natural pruning, and the good working quality of the wood. Therefore, yellow poplar (Liriodendron tulipifera L.) has been adopted in South Korea for decades ago, and its cultivating the saplings and silvicultural system have been studied. However, yellow poplar is still embroiled in controversy for utilization of use and worth. This species has not only advantages such as lower weight, light color, and higher machinability and bending processing, but also has disadvantages which are bad smell and different colors on heartwood and sapwood. In this study, the objective was that use of yellow poplar board as furniture materials by drying and painting process. Thirty years old yellow poplar was cut and dried for 7 days by high-frequency dryness. Adjustment of color tone to walnut color was conducted with multiple colorants and various number of spread times. Uniform color of yellow poplar on heartwood and sapwood was accomplished by applying 1 time stain (green), 2 times transparent primer, 1 time middle-painting (walnut), and 2 times top-painting (walnut) in sequentially. The painted yellow poplar board was used to manufacture table and dressing table. During the furniture manufacture process, no critical issues were occurred on part of jointing and painting. This painting method may be useful data for future use of yellow poplar as furniture materials.

Surface sediment samples collected from the eastern half of the Yellow Sea proper in 1998 were analyzed for polycyclic aromatic hydrocarbons (PAHs), ubiquitous pollutants. Total PAHs concentrations varied from 1.0 to $320.5ng\;g^{-1}$ dw. Relatively high concentrations of PAHs were found in the muddy central part of the Yellow Sea. Sedimentary total PAHs concentrations in the Yellow Sea proper were similar to those of Californian offshores and the central Mediterranean Sea, albeit an order of magnitude lower than the Yellow Sea nearshore areas. Phenanthene/Anthracene concentration ratio of PAHs in bottom sediments suggested that pyrolytic PAHs might be dominant over petrogenic ones in the eastern Yellow Sea. Downcore depth distributions of PAHs from the relatively undisturbed core samples of the central Yellow Sea showed decreasing PAHs concentrations with core depths and suggested that the Yellow Sea has been increasingly exposed to PAH for decades. Annual total PAH flux to these sediments was estimated to be $166{\mu}gm^{-2}yr^{-1}$ in the central part of the Yellow Sea for the recent decade.

The principal objective of this study was to assess the effects of maesil extract on yellow layer cake made with medium and cake flour. After making yellow layer cakes with maesil extract, water activity, hardness, Max G, springiness and crumb color were evaluated. During storage, the Aw of the yellow layer cakes prepared with maesil extract did not retain its consistency. The hardness, Max. G. and springiness of the yellow layer cakes prepared with maesil extract were all lower than that of the controls. With regard to the color of the yellow layer cakes, the L values were reduced, but the a and b values were increased with the addition of maesil extract. The micrographs of the yellow layer cakes prepared with maesil extract evidenced slightly higher porosity than was observed in the controls. This meant that the cake batter prepared with maesil extract could be used to create yellow layer cake with good volume and good quality.

In order to understand the water masses and their distribution in the eastern Yellow Sea from winter to spring, a cluster analysis was applied to the temperature and salinity data of Korea Oceanographic Data Center from 1970 to 1990. From December to April, Yellow Sea Cold Water (YSCW) dominates the eastern Yellow Sea, whereas Eastern Yellow Sea Mixed Water (MW) and Yellow Sea Warm Water (YSWW) are found in the southern part of the eastern Yellow Sea. MW appears at the frontal region around $34^{\circ}N$ between YSCW in the north and YSWW in the south. On the other hand, Tshushima Warm Water (TWW) is found around Jeju Island and the South Sea of Korea. These water masses are relatively well-mixed throughout the water column due to the winter monsoon. However, the water column begins to be stratified in spring due to increased solar heating, the diminishing winds and fresh water discharge, and the water masses in June may be separated into surface, intermediate and bottom layers of the water column. YSWW advances northwestward from December to February and retreats southeastward from February to April. This suggests a periodic movement of water masses in the southern part of the eastern Yellow Sea from winter to spring. YSWW may continue to move eastward with the prevailing eastward current to the South Sea from April to June. Also, the front relaxes in June, but the mixed water advances to the north, increasing salinity. The salinity is also higher in the nearshore region than offshore. This indicates an influx of oceanic water to the north in the nearshore region of the eastern Yellow Sea in spring in the form of mixed water.
