  • The aim of this study was to develop rice cookies based on 'Goami 2' rice, and made with sesame (white and black) and perilla seeds. Furthermore, we studied the physicochemical and sensory characteristics of the cookies as well as the alternative effects of the sesames or perilla seeds for butter, where we substituted the sesames or perilla for 30% of the total butter. The pH values of the cookie doughs made with the sesames or perilla seeds were significantly different (p<0.001), whereas the spread factors of the doughs were not significantly different. The Hunter color L-, a-, and b- values were significantly different for the cookies made with the added sesames or perilla seeds (p<0.001). The brittleness of the Goami 2 rice cookies (control) was significantly higher than that of the cookies made with the sesames or perilla (p<0.001). In a descriptive analysis performed by 8 trained panelists, the following sensory characteristics: yellow, black, sweet taste, nutty taste, nutty odor, oily flavor, and off flavor, were significantly different among the cookie samples. In a consumer test by 50 women students, the Goami 2 rice cookies were preferred in the following order: Goami 2 rice cookies with no additions > black sesame cookies > white sesame cookies > perilla cookies. In conclusion, some physicochemical and sensory characteristics of the cookies were different, in relation to being made with or without the sesame or perilla seeds. However, because of the small difference in acceptance among the cookies, the sesame and perilla rice cookies show strong potentials for consumer acceptance. Moreover, the black sesame cookies were more acceptable in terms of butter substitution for the cookie preparation.

  • An investigation was carried out to elucidate the effects of type of ginseng, concentration of ginseng, and type of coagulants on the physical and sensory properties of soybean curd. The textural properties of soybean curd were not influenced by the type of ginseng. Soybean curd coagulated with glucono-delta-lactone (GDL) showed a greater hardness than that coagulated with other coagulants, whereas the former produced a lesser springiness than the latter. The L-value was proportionally reduced by the increase of ginseng level and soybean curd coagulated with $CaCl_2$ showed the lowest L value. All the curd products prepared with ginseng had a pale yellow color. In the sensory properties, springiness and beany taste of soybean curd linearly decreased as the concentration of ginseng was increased. The concentration of ginseng to improve the acceptability of ginseng soybean curd as determined by the physical and sensory evaluation, was less than 0.25%. The most acceptable ginseng soybean curd was the one coagulated with $MgCl_2$. Soybean curd prepared with GDL had the lowest acceptability because of its sour taste and textural properties.

  • The early history of Korean mandarin fish, Siniperca scherzeri was studied to obtain some information required in aquaculture and reinforcement of natural population. During the period from June 1996 to July 1997, the mature adults of Siniperca scherzeri were collected from the middle Soyang Lake at Puksan - myon, Chunchon - shi, Kangwon - do, Korea. The eggs from females were obtained by injecting HCG or/and GnRH - a and fertilized by dry method in the laboratory. The fertilized eggs, measuring 1.70~2.10 mm in diameter and expanded to 2.20~2.66mm after absorption of water, were globosity, light orange yellow, separative, submergence and had one large oil globules of 0.5~0.7 mm. The blastodisc was formed in 1 hour and cleavage started in 1 hour 30 min. after fertilization, and the intervals of each stage of cleavage was about 50 min. at the water temperature of $21{\sim}24^{\circ}C$. Hatching occurred 131 hours 30 min. after fertilization and newly hatched larvae were 5.86~6.85 mm in total length(TL) and numerous stellate melanophores were distributed on the yolk and abdomen of caudal peduncle. The yolk was almost absorbed and the teeth development. 3 days after hatching, at 6.98~7.60 mm TL. The head spines and the teeth were largely developed and all fins were completely formed and became postlarva stage 15 days after hatching, at 10.10~12.90 mm TL. The body shape and the color pattern were similar to adult, 25 days after hatching, at 15.3~23.8 mm TL. In 5 months after hatching were reached at 154.10~175.02 mm TL and 49.32~82.67 g in body weight.

  • This experiment was conducted to develop control method for Bemisia tabaci (Gennadius) on eggplant using sticky trap method. According to the color of the sticky traps, the attractiveness of the B. tabaci was the highest in the yellow trap, followed by the green and orange. However, white, blue, red, black and green sticky traps have reduced attractiveness of B. tabaci. In order to improve the efficiency and attractiveness of sticky trap to the B. tabaci, the different kinds of sugars such as glucose, fructose, oligosaccharide, starch syrup and pure sugar were added to sticky traps respectively. However, the effect of B. tabaci attractiveness was low in starch syrup, pure sugar, and non-treated sticky traps. The attracting effect of B. tabaci was depending on the location of sticky trap. The highest value was obtained where sticky traps were located in the top of the eggplant, followed by 30 cm above from the top level. In addition, we were installed up to 40 sticky traps to determine the optimal amount of sticky traps to control B. tabaci in eggplant. When increasing the sticky traps, the number of adult and nymphs of B. tabaci were tended to be decreased significantly. This tendency was more effective in the latter stages than in the early stages. As the number of sticky traps increased, not only the growth rate of eggplant, leaf length, and stem diameter were to be better. But also number of fruits and product marketable value were increased at the early stage of growing as well. The study had proven that the sticky traps had an effect on increasing the yield at the early stage of growth, but the efficiency of controlling decreased due to the high density of B. tabaci of the next generation.

  • An analytical method of nine synthetic food colors in Korea, Japan, Joint FAO/WHO Expert Committee of Food Additives (JECFA), and USA were compared. Contents of water insoluble matter in synthetic food colors tested were not different by general test methods of various organs. Contents of chloride and sulfate salts in Food Green No.3, Food Red No.3, Food Blue No.2, and Food Yellow No.4 slightly differed in various methods, and but up to the standard, and general test methods of JECFA and USA needed far more time. For the measurement of arsenic contents in food colors, colorimetric method in Korea and Japan, and silver diethyldithiocarbamate colorimetric method in USA and JECFA were used, but the standards of them were different. Content of heavy metals was up to the standard, but the methods were used colorimetric method in Korea, atomic absorption method in Japan, and both methods in JECFA and USA.

  • This study was conducted to elucidate the characteristics of soybean sprouts cultured in water containing germanium. In three varieties of Eunhakong, Seomoktae and Subaktae, the yields of germanium soybean sprout were 10~20% more than those of control soybean sprouts after 5 day-cultivation. The hypocotyl of germanium soybean sprouts was thicker than that of control soybean sprouts, but there were no significant differences in the length of hypocotyl and the thickness of cotyledon. Germanium soybean sprouts showed deeper green and yellow color than control soybean sprouts. In addition, the hardness exhibited strongly in germanium soybean sprouts, especially Seomoktae. In the sensory evaluation, germanium soybean sprouts were better than control soybean sprouts in appearance, taste, flavor and preference.

  • Dragon robe was defined as a robe on which the principal design consisted of dragon. Dragon patterns have been used on princess robes during T'and Dynasty. In Sung, Dragon-figured robes seem to have an Imperial prerogative. Yuan took over the use of robes with dragons patterns as a definite institition. Ming tried to reject all Yuan innovations, the dragon robe was retained as an unofficial court costume. The Emperor's semiformal robes which at first had four dragon medallions, later had twelve along with the 12 Symbols(십이장문). As Ch'ing dragon robes were only intended fro semiformal use. The Later Ch'ing robes date from after 1719, when the Ch'ien-lung(건륭) introduced 12 Symbols on Ch'ing robes. The Ch'ien-lung laws were disobeyed, notably the ones that specified the number of claws on the dragons. THe Emperor's dragon robe, lung-p'ao, (용포) was described as bright yellow in color, having four slits and horsefoof cuffs. The basic pattern consisted of nin dragons, in addition it had 12 Symbols. The elaborate textile techniques reached their peak in Ch'ing Dynasty-with its Weaving and Dyeing Office in Peking, and this factories at Hangchow(항주), Soochow(소주), and Naking(남경) -helps to explain why the decay of the Ch'ing bureaucracy hastended the decline of dragon robes. In the Ch'ing Dynasty tow terms were used for dragon robe, depending on the number of claws on the dragons. Those with five-clawed dragons were called lung-p'ao, while those with four-clawed dragons were called mang-p'ao(망포). The Court felt compelled to take corrective meausres. It decreeed that Ninisters of State and other officials, who had been bestowed five-clawed lung dragons, must take out one claw. Finally, the sale of ranks and the attendant privilege of wearing dragon robes gradually increased during the 18 th century, reaching its height in the 19 th century, Finally, after the Taiping Rebellion, when the Imperial Treasury was depleted by the wholesale destruction of revenue-producing lands, the Chinese government came to depend on such sales as an important source of revenue and the practice became even more widespread. The ensuing mass production of dragon robes, and the necessity of conforming to the fairly rigid basic pattern established in 1759, resulted in marked deterioration of workmanship, and a comparative monotony of decoration. The patterns on the dragon robes slight changes continued to be made in the ways of representign them. The li shui (입수) portion at the base of the robe become inreasingly wider throughout the 19th century. The background became cluttered with symbols of good fortune, scattered among the clouds and waves. As a result of all this extraneous decoration, the dragons were so crowded that they had to shrink back into the small size that they had originally occupied in the medallons. Kuang-hsu(광저) was a long one, allowing time for the manufacture of numerous robes. Also, it would seem likely that Occidental museums and collections would have a considerable number of his robes, in view of the widespread looting of his palaces during the Allied occupation of Peking in 1900, and the frequent sales of Late Ch'ing imperial textiles by destitute Manchu courtiers in the '20's.

  • Forest green mold incidence rate, extent of damage according to the inoculation periods, and its cultural characteristics were observed in the automatic cultural system of the winter mushroom, Flammulina velutipes. The incidence rate of the forest green mold was 7.7% in early cultivation stage and slowly increased to 14.9% in harvest stage. When the forest green mold was inoculated at cultural period, the rate was recorded at 100%, but the extent of the damage increased up to 40% (+++). There was also 100% incidence rate at early pinheading time, whereas the yield of mushroom decreased to ++ $(10{\sim}39%)$. The rate of forest green mold was greatly decreased to 34.4% at 10 days after pinheading, and its damage extent was also below 10%. A pathogen to infect the winter mushroom was identified as Trichoderma pseudokoningii. It's optimum temperature for mycelial growth is $25^{\circ}C$, and it grew 2.6 times faster than that of F. velutipes. The mycelial color of T. pseudokoningii was pale yellow or olivaceous in shades on PDA medium. Phialospore was one celled, and ellipsodal or obovoid, smooth walled, and measured $1.3{\sim}3.0{\times}1.0{\sim}2.5\;{\mu}m$. It aggregated in small heads at the tips of the phialides. The phialides were $3.2{\sim}9.2{\times}2.0{\sim}5.5\;{\mu}m$ and were of bowling pin type, solitary and alternate or more irregularly disposed at the conidiophore apex, T. pseudokoningii depressed the F. velutipes growth at the crossing cultivation when they were simultaneously. FV 4-1 (F. velutipes) cultivar was less depressed by T. pseudokoningii, but had a lower cross growth rate than the other four cultivars.

  • Recent studies demonstrated that the combination of chlorhexidine (CHX) and sodium hypochlorite (NaOCl) resulted in the formation of a precipitate, para-chloroaniline (PCA). Alexdidine (ALX) is a kind of biguanides like CHX, and has stronger detoxification effect against the bacterial virulence factors such as lipoteichoic acid and lipopolysacchardide compared with CHX. The purpose of this study was to determine whether PCA was formed after chemical interaction between ALX and NaOCl using mass spectrometry. Mass spectrometry was performed for the mixture of five different concentrations of ALX (1, 0.5, 0.25, 0.125, 0.0625%) and 4% NaOCl. Results showed that the peak of PCA was not detected in mixed solutions of ALX and NaOCl in mass spectrometry analysis. The color of mixed solution of ALX and NaOCl after chemical interaction was light yellow to white, but there wasn't any precipitate found.
