To investigate the effects of yellow soybean powder on serum lipid level and enzyme activities, male Sprague-Dawley(SD) rats were given hyperlipidemic diets for 6 weeks. Rats(n=8) were divided into three groups consisting the normal group(N), hyperlipidemic diets group(C) and hyperlipidemic diets and yellow soybean powder group(YSP). YSP group lowered triglyceride, total lipid, phospholpid, ester-cholesterol and free-cholesterl than control group. YSP group lowered total-cholesterol, VLDL-cholesterol and LDL-cholesterol but increased HDL-cholesterol of the serum compared to the control group. Athergenic Index(AI) and LHR(LDL-cholesterol/HDL-cholesterol ratio) of YSP group was decreased by control group (p<0.05). On the other hand, glutamic oxaloacetate transaminase(GOT), glutamic pyruvate transaminase (GTP), lactate dehydrogenase(LDHase) and alkaline phosphatase(ALP) enzymes activities were decreased by hyperlipidemic diets group (C). These results suggest that yellow soybean powder fed a lipid lowering effect in serum of rats.

To investigate the effect of yellow dust on phytoplankton, a field survey and physiological experiments were carried out in the waters near Taean Peninsula from April 22 to 26, 2006, when yellow dust occurred. Phytoplankton populations during the yellow dust period were in the range of $26{\sim}290{\times}10^3cells{\cdot}L^{-1}$, a somewhat low standing crop. An increase in diatoms (a main taxonomic group), especially benthic diatoms such as Paralia sulcate, a typical species for active mixed sea water areas, was also remarkable. In addition, the Chl-a concentration after yellow dust exceeded the Chl-a concentration change range according to the tide before yellow dust. As the concentration of yellow sand increased in a yellow sand treatment experiment, primary productivity decreased, and the maximum assimilation number showed the same tendency. In the 48h culture experiment, primary productivity of the test group was lower than that of the control group at the early stage (T0) of yellow sand treatment, but after 48 hours (T48), the test group showed higher primary productivity than the control group. In particular, the primary productivity of the test group significantly increased to 321 % after 48 hours. Therefore, strong physical environment accompanied by yellow dust may temporarily inhibit the growth of phytoplankton in the waters adjacent to China in the early stage of yellow dust, but the formation of stable water mass has also been identified as a potential factor promoting the growth of phytoplankton.

This study was designed to observe the effect of hot water soluble polysaccharides extract(PS) from Lentinus edodes on the enzyme activities related with hepatic function and peroxidation in the rats fed better yellow. The four groups of male SD rats were fed with the diets contained 15% casein(basal diet; NO group), added butter yellow(BO group) or /and PS(NP, BP group) for 6 weeks. The activities of ${\gamma}$-GTP and GPT in BP were significantly lower compared with BO. The activities of glutathione peroxidase, catalase and lactate dehydrogenase were not significantly different between NP and NO, while those activities were significantly lower value in BP than BO. The activities of glutathione S-transferase of the microsomal and cytosol fractions were significantly lower in BP than in BO. The contents of glutathione and malondialdehyde in the liver were considerably low value in BP. In a view of these results the PS of Lentinus edodes prevents the lipid peroxidation and diminishes the liver toxicity caused with better yellow. The superoxide dismutase activity in cytosolic fraction of liver was not found any effect in all groups. But hepatic function enzyme activities such as catalase and glutathione peroxidase, LDH activities were remarkably decreased in the groups 2(basal diet + PS) and the ${\gamma}$-GTP, GOT and GPT activities, too. In liver, the contents of glutathione decreased by PS supplementation but HDL-cholesterol and total cholesterol ratio in plasma decreased at the groups 3, 4. The ${\gamma}$-GTP, GOT and GPT in plasma were remarkably higher in the rats fed the p-DAB than the control group, too. But above enzyme activities significantly decreased in the groups fed PS.

The purpose of this study is to investigate the effect of tone-on-tone coloration on the visual images of traditional Korean dress. The materials in the experiment developed for this study were made up of various stimuli and the response scales for each stimulus. The stimuli were 48 color pictures with various combination of colors, in which the tones of jackets and skirts were manipulated by computer drawing. 24 bi-polar adjectives, each of which was graded into seven in its degree, were used to evaluate each image. The subjects were 576 female students in Jinju City. This experiment was based on the $3{\times}4{\times}4$ factorial designs: color (red, yellow and green), jacket tone (vivid, light, dull and dark) and skirt tone (vivid, light, dull and dark). The results of the study can be summarized as follows; Impression factor of the stimuli consisted of the 5 different dimensions - youthfullness and activity, attractiveness, gracefullness, visibility, and tenderness. The colors and the tone of jackets and skirts used in this experiment influenced 5 impression dimension by interaction of two valuables or working independently. Yellow and green with vivid or light tone had an effect on the formation of youth and activity image, and dark-light combination had an effect on the formation of attractiveness image. In case of green color, light tone of a jacket and vivid or dull tone of a skirt affected gracefulness, while yellow has no impact on visibility image regardless of skirt tone. Red and yellow with vivid or light tone were a factor to decide tenderness.

This study was undertaken to determine the effect of yellow and black soybeans on plasma and hepatic lipid composition and fecal lipid excretion in Sprague Dawley rats. Animals were fed with diets containing 52% yellow soybean, 50% black soybean, or 20% casein for 7 weeks. Feeding efficiency was significantly increased in the animals fed soybeans(p<0.05). Plasma cholesterol concentration was significantly lowered in the group fed yellow soybean compared with black soybean and casein-fed control (p<0.05). Hepatic triglyceride concentration was significantly lowered in soybean groups compared with casein-fed control(p<0.05), whereas hepatic cholesterol concentration was not affected by diet treatments. Soybean feeding significantly increased fecal weight, triglyceride and bile acid contents compared with casein feeding(p<0.05). It is concluded that soybean feeding in rats affects plasma and hepatic lipid levels by increasing the excretion of triglyceride and bile acids.

This study was conducted to investigate the characteristics of oviposition and the effect of density suppression by yellow-colored sticky trap on Ricania shantungensis in blueberry. The occurrence of an egg mass of R. shantungensis in the upper, middle and lower region were 56.6~60.2%, 23.8~28.1% and 11.7~19.7%, respectively. The number of egg masses in the branch was investigated. Percentage of the branch with one egg mass was greatest (50.9%) than with two (20.5%), three (14.6%) and over four (14.0%). The effect of yellow-colored sticky trap to reduce the number of R. shantungensis egg masses in blueberry was also investigated. In a month after yellow sticky trap installation, 17.1 adults of R. shantungensis were attracted per trap. Moreover, the number of egg masses on a tree in yellow-colored sticky trap plot was much lower (0.4) than control (1.3). Consequently, this result shows that use of yellow-colored sticky trap may contribute to decrease ovipisotion rate of R. shantungensis in blueberry.

The purposes of this study were to investigate characteristic changes on nonwoven fabric by the charcoal and the yellow soil printing. It separate the grind charcoal and the yellow soil as two different size of particles $45{\sim}52{\mu}m\;and\;53{\sim}65{\mu}m$ for hand screen printing on three kind of nonwoven fabrics. To examine the effect of the charcoal and the yellow soil printing on nonwoven fabric were to observe surface changes by a scanning electron microscope, dyeability by using spectrophotometer, moisture regain by oven method, deodorization and antibacterial activity. The results were as follows: When the charcoal and the yellow soil powder concentration increased from 3 to $9\%$ or from 5 to $10\%$, K/S value also increased from 3.06 to 8.55 or from 1.14 to 1.80. The charcoal and the yellow soil moisture regain also increased. In same concentration, moisture regain occurred higher as particle of small size. In concentration of charcoal $3\%$, rate of deodorization measured as $89\%,\;83\%\;and\;87\%,\;and\;9\%$ concentration caused $96\%,\;86\%\;and\;93\%$ of high deodorization. In concentration of 5, $10\%$ of yellow soil, rate of deodorization measured as $85\%$ over. Antibacterial activity examination in nonfinished nonwoven fabric resulted range of $60\%$, however, $3\%\;and\;9\%$ concentration finished nonwoven fabric resulted $99.9\%$ of excellent antibacterial activity. Also $5\%,\;10\%$ yellow soil concentration was appeared same resoult.

To investigate the antioxidative effect of Korean soybeans, four kinds of soybeans(yellow, brown, black and small black bean) were selected and determined their antioxidative activities in vitro by POV method. Dark colored soybeans such as brown, black and small black soybean showed stronger antioxidative effect than pale yellow one. When compared the antioxidative effect of these soybeans in hull and dehulled condition, in dehulled soybeans, they showed the same antioxidative effect in each soybeans, but in soybean hull, dark colored soybeans showed stronger antioxidative effect than yellow soybean hull, which means the pigments of soybeans play important roles in their antioxidative activities. To separate the main components showing antioxidative effect in soybeans, these soybeans were extracted with hexane, methanol and water. The methanol extract showed the strongest antioxidative effect among them, which means the major antioxidative effect materials contained in methanol extract.

The choice behavior of the octopus in response to the environment-friendly colored sinker for octopus driftline and the sinker's fishing effect were studied under experimental conditions in the water tank and the field. The colors of the sinkers used for the experiment are white, black, yellow and green. Artificial baits are attached to the sinkers in order to attract the octopuses in the experiment. In the water tank experiment, two sinkers of two different colors are placed in a compartmentalized corner of the rectangular tank, and a CCD camera records the choice behaviors of the octopuses to the colored sinkers. In the field experiment, the catch investigation of octopus for each colored sinker was conducted 14 times in total by using 2(A, B) commercial fishing boats at the coast of Gangneung within 30m of depth in 2006. The number of colored sinkers per operation was a total of 24-40 pieces with the same number of sinkers individually for four colors. As a result, it was found that the octopus selected white the most followed by black and yellow in their choice of colored sinkers in the water tank experiment, and green was the lowest in their choice. Even in the field experiment, the sinkers of white and black showed a higher catch of octopus than the sinkers of yellow and green.

The antimutagenic effects of insoluble dietary fibers(IDF) extracted from some green-yellow vegetables(kale, carrot, spinach, broccoli and soybean sprout) and soybean by binding the carcinogens of MeIQ (2-amino-3,4- dimethyl-imidazo(4,5-f) quinoline) and Trp-P-2(3-amino-1-methyl-5H-pyrido[4,3-b] indole) in Salmonella tylhimirium TA100 and TA98 were studied. All of the insoluble dietary fiber samples which binded MeIQ exhibited high antimutagenic effects by removing the mutagen. Among the samples, IDFs from kale and soybean showed strong binding capacity fo the carcinogen and revealed about 90% of the antimutagenic activity. the IDF samples showed somewhat lower binding capacity to the Trp-p-2. The lignin which extracted from kale, soybean and carrot, and the cellulose strongly removed the mutagenicity of MeIQ by the binding. Among the samples, the level of lignin in kale revealed the highest(about 10%), and it seemed that the higher content of lignin in kale is one of the reasons to increase its antimutagenic effect.
