This study was conducted to investigate the distribution pattern, ecological characteristics and life cycle of the Black Soldier Fly (Hermetia illucens, BSF). The BSF was widely distributed throughout Korea. The insect was mainly found in the vicinity of and in cattle sheds, manure sheds, living waste dump grounds, and food waste dump grounds. Developmental characteristics of the BSF are as follows: the egg was long oval shaped of 887 ${\mu}m$ in the major axis and 190 ${\mu}m$ in the minor axis; it weighed 24 ${\mu}g$. Female oviposited ca. 1,000 eggs on average; eggs hatched in 81 hours under laboratory condition ($27^{\circ}C$, 60% R.H.). The duration of the larval stage was approximately $15{\sim}20$ days. The size of the last instar larvae was 21 mm. The cuticle of the pupae gradually acquired red-brown color and the size of them was 19 mm. The pupal stage was shorter for females (16 days) than males (15 days). Adults were sized about $13{\sim}20$ mm long and black-colored. The life span of adult insects was $5{\sim}8$ days for the first generation (June${\sim}$July), $7{\sim}10$ days for the second generation (Aug.${\sim}$Sept.), and $13{\sim}18$ days for the third generation (Sept.${\sim}$Oct.). Mating started on the next day of emergence and actively occurred at the third day after emergence. Mating mostly occurred between 10:00 and 16:00 during which light intensity is highest. Egg-laying started on the third day and was most frequent from the fourth to the sixth day after emergence. Similar to mating time, females oviposited mostly between 10:00 and 16:00.

This study conducted a survey on the moulting sequence subsequent to age of Haliaeetus pelagicus raised in captivity at the Ornithology Laboratory attached to Kyungsung University for about six years from November, 2000 until July, 2006. The survey indicated that the moult of rectrices usually began in July and continued until April of the next year and most of the rectrices were replaced by one-time moult. Usually, about two thirds of the tail feathers were replaced while the rest were replaced no later than April of the next year, and the moult also continued during the wintertime. The total number of rectrices was 14, and the moult progressed alternately on a systematic basis. The progress of the moult for female & male was made on four stages and three stages respectively and the characteristic shown on every stage of the moult was that the left & right tail feathers progressed symmetrically and not until one stage of progress almost completed did the next stage began. The color of the juvenile steller's sea-eagle was dotted with black spots on its original white color and there existed regular black belt on its feather's fringes; however, it was difficult to identify its age by tail feathers only because there was almost no difference in color between feathers ranging from the first to the third generation(1st-3rd summer feathers). In addition, this research took the different amounts of black-speckled pattern appearing by individual into consideration. There existed slight black speckles in white color feathers of the fourth generation(the 4th summer feathers) while showing a big difference compared to the 3rd generation feathers. The 5th generation feathers[the 5th summer feathers]were found to be equipped with perfect tail feathers having virgin white of a steller's sea-eagle after completing its 4th molt. When observing a steller's sea-eagle in the open air, it is necessary for an observer to have a deliberate examination in judging its age belonging to the 1st-3rd generation feathers, and it is considered that the changes of other parts of feathers should be also observed besides tail feathers.

In comparison of the body color of Zacco platypys from Korea, it was found that there were significant differences among geographical populations in the color of upper eye, snout tip and anterior margin of pectoral fin. In individuals with red upper eye the snout tip was red but in those with black upper eye red color did not appeared on the snout tip. There was no difference between male and female in this characteristic and it was expressed uniformly within the same population. So we divided Z. platypus into two types by the color of upper eye; R type with red upper eye and B type with black upper eye. Red band on anterior margin of pectoral fins appeared in all males of both R and B type populations but in females it appeared only in B type individuals. The two types shown different distribution pattern in Korean Peninsula. R type distributed in almost whole area but B type distributed only in southeastern part of the peninsula: Nakdong, Hyeongsan, Taehwa, Suyeong and Jinjeon River. In analysis of external morphology among two types of Z. platypus from Korea and Z. platypus from Japan, there were no significant differences. But they were relatively well separated in discriminant function analysis.

The purpose of this study is to better understand the development and characteristics of knitwear fashion design by examining the transformation process of the modern knits. The subjects of the study are Missoni, Sonia Rykiel, and Azzedine Alaia, designers who are world-renowned knit designers, and the expressive techniques in their designs will be evaluated. The study also intends to analyze the aesthetic value of each designer's style through their product's silhouette, colors, and knitting techniques. On the basis of the analysis, we hope to research the factors in the designing process that will allow knits, which were made for practical purposes, to be valued as a luxury fashion item, and with the results, show the potential for knits in expanding its domain in fashion to become a more luxurious, creative fashion item. The characteristic comparison of the designers is as follows: First, in the case of colors, Missoni shows its distinct identity through a balance of splashy colors as well as nature-inspired color composition and balance. And, only with color use, is also able to express perspective, form composition, and rhythm. Sonia Rykiel designs are composed of black backgrounds with strong primary colors that are contrasted with one-point or stripes to express a light, urban image. Alaia emphasizes femininity by the use of black and white colors, which show modernity, in combination with neutral skin-toned colors, such as beige and gray. So, in other words, Missoni and Sonia Rykiel mixed colors for visual interconnectivity, while Alaia expressed femininity through the use of an achromatic color. Second, in the case of knitting techniques, Missoni uses the jacquard technique to make complex patterns that show balance of colors and patterns such as zigzag, stripe, geometries, and titan check, which are geometric, abstract, and symmetric. Sonia Rykiel who uses stripes as her trademark, most often utilizes the intarsia technique, which is expressed through one-point. Alaia combines diverse techniques, such as the Skashi weaving, by using computerized knitting. Third, as for silhouettes, Missoni eliminated exaggerated details in order to emphasize the flashy colors and delicate patterns and weavings of its designs, and this resulted in simplistic and relaxed silhouettes. Sonia Rykiel took advantage of the elasticity that the knit offers to get a tight silhouette, and in turn, emphasized the female sensuality. Alaia used curvilinear cuts that emphasized the womanly curves and gained an image considered soft and feminine.

1. About fifty thousand of cattle embryos were transferred and 16000 ET-calves were born in 1999. Eighty percents of embryos were collected from Japanese Black beef donors and transferred to dairy Holstein heifers and cows. Since 1985, we have achieved in bovine in vitro fertilization using immature oocytes collected from ovaries of slaughterhouse. Now over 8000 embryos fertilized by Japanese Black bull, as Kitaguni 7~8 or Mitsufuku, famousbulls as high marbling score of progeny tests were sold to dairy farmers and transferred to their dairy cattle every year. 2. Embryo splitting for identical twins is demonstrated an useful tool to supply a bull for semen collection and a steer for beef performance test. According to the data of Dr. Hashiyada(2001), 296 pairs of split-half embryos were transferred to recipients and 98 gave births of 112 calves (23 pairs of identical twins and 66 singletons). 3. A blastomere-nuclear-transferred cloned calf was born in 1990 by a joint research with Drs. Tsunoda, National Institute of Animal Industry (NIAI) and Ushijima, Chiba Prefectural Farm Animal Center. The fruits of this technology were applied to the production of a calf from a cell of long-term-cultured inner cell mass (1988, Itoh et al, ZEN-NOH Central Research Institute for Feed and Livestock) and a cloned calf from three-successive-cloning (1997, Tsunoda et al.). According to the survey of MAFF of Japan, over 500 calves were born until this year and a glaf of them were already brought to the market for beef. 4. After the report of "Dolly", in February 1997, the first somatic cell clone female calves were born in July 1998 as the fruits of the joint research organized by Dr. Tsunoda in Kinki University (Kato et al, 2000). The male calves were born in August and September 1998 by the collaboration with NIAI and Kagoshima Prefecture. Then 244 calves, four pigs and a kid of goat were now born in 36 institutes of Japan. 5. Somatic cell cloning in farm animal production will bring us as effective reproductive method of elite-dairy- cows, super-cows and excellent bulls. The effect of making copy farm animal is also related to the reservation of genetic resources and re-creation of a male bull from a castrated steer of excellent marbling beef. Cloning of genetically modified animals is most promising to making pig organs transplant to people and providing protein drugs in milk of pig, goat and cattle. 6. Farm animal cloning is one of the most dreamful technologies of 21th century. It is necessary to develop this technology more efficient and stable as realistic technology of the farm animal production. We are making researches related to the best condition of donor cells for high productivity of cloning, genetic analysis of cloned animals, growth and performance abilities of clone cattle and pathological and genetical analysis of high rates of abortion and stillbirth of clone calves (about 30% of periparutum mortality). 7. It is requested in the report of Ministry of Health, labor and Welfare to make clear that carbon-copy cattle(somatic cell clone cattle) are safe and heathy for a commercial market since the somatic cell cloning is a completely new technology. Fattened beef steers (well-proved normal growth) and milking cows(shown a good fertility) are now provided for the assessment of food safety.

Up to now, image of femme fatale has undergone constant transformation to be inherited and developed through various genres of movies. With few exceptions such cases have represented sensuality of women by costumes with the most distinctive and exaggerated sexuality. Temptresses in movies are mostly drawn as extravagant and gorgeous one or a gloomy and dreary woman. Such an image is reinforced with make-up, hair style, accessories, attitude and manner of talking. The movie 'Chicago' is a musical film that crosses the boundaries of reality and fantasy with dancing and singing. Its lighting, stage setting, powerful and sexy dancing augmented already exaggerated and sensual costumes. Following is the analysis of costumes for two heroines as images of femme fatale. Strong contrast of color among black, red and blue on see-through & stickingly tight body suit signifies liberal mind and arrogant charisma of Velma. The contrast, haughty gestures, cropped black hair and thick makeups represent sex appeal, aggressive image, and fearlessly determined character of femme fatale. Roxie wears decent dresses in front of public and gorgeous stage costume in fantasy to convey two images of bad girl and angel. Her body suit, showing off lustering materials and dazzling bead decoration, is rather loose but still displays her bodyline to emphasize sexiness for representation of desire in fantasy. Chastity and innocence are implied with the decency of dresses in reality. They were specially chosen to draw public sympathy and indicate cunning disguise of Roxy who desperately wants to realize her desire. These dauntless costumes, which sufficiently express inside aspirations of Velma and Roxie later denote open and realistic social yearning rather than fatal desire hidden behind sensual beauty. It doesn't exist as imperfect, unrealistic and socially disdainful ambition as the image of femme fatale of paintings and movies did before in history. Femme fatale is expressed with deep cleavage, silk dresses that explicitly display bodyline, sexiness of mesh stockings with garter belts. All of these won't be utilized as a negative tool to seduce and destroy someone anymore but rather, they should represent rightful and fair nature of humans such as men's curiosity who secretly steal a look at them or female sexuality that women spontaneously want to show off.

This study was carried out to investigate fatty liver in Korean black goats. Adult female goats were divided into 3 test groups(A, B and C). Group A and B of goats each received 3 test consecutive daily doses of DL-ethionine at 75mg/kg and 150mg/kg body weight, respectively. Group C of goats was given 3 consecutive doses of the compound every 48 hours at 150mg/kg body weight. The clinical symptoms, hematological values, serum chemical values and histopathological study of the liver were investigated in the test animals. The results obtained are as follows ; 1. Fatty liver were observed in every test animal. 2. Some clinical symptoms( anorexia, depression) were appeared from 1st day to 7th day after administration of the compound in every test animal. In addition to these symptoms, diarrhea and salivation were generally observed in test animals which were given the compound at 150mg/kg body weight. The degree of these symptoms was dose dependent. 3. There was no significant variations in total WBC counts and fibrinogen values in the blood of test goats. The PCV values were significantly increased on 5th day of dosing in group A and B of goats. 4. The total lipid value was not changed but the concentration of NEFA was significantly increased on 3rd day of dosing with the compound and returned to normal value after 10 days hereafter. The value of triglycerides was significantly increased on 1st day and returned to normal value on 3rd day of dosing. The value of cholesterol was significantly decreased on 3rd day and returned to normal value on 10th day after treatment. 5. Total protein level was decreased on 10th day of dosing in the groups of B and C, and billirubin level was significantly increased on 7th day of dosing in every test group and returned to normal level after 13th day of administration. 6. The activity of GGT in serum was not changed while the activities of SDH and AST were significantly increased in every test goat and those values were returned to normal after 10~13th day of trestment. 7 The 35K-protein fraction in serum was not detected by SDS-polyacrylamide gel electrophoresis, but this protein fraction was detected by the same method after treating the 21st and 22nd fraction which were obtained by column chromatography with Sephadex G-100. 8. The affected liver was congested and swollen on 3rd day, and yellowish brown in color and mottled appearance on 7th day of treatment. Histopathologically, fat droplets were common in the hepatocytes, this change was intensive on 7th day after treatment in group B and C. Hepatic cell necrosis was observed in some livers but this pathological change was disappeared and returned to normal after 13 days of treatment.

Four strains of Beauveria bassiana F101, F587, F9 and FJ8, were received from Forestry Research Institute,Seoul. The strain, B. bassiana F101, was the most active in the enzymatic activity and spore production. Whenspores of B. bassiana FlOl were sprayed on the female larva of the black tipped sawfly with various concentrationsof 6 xl 0'~-10s~p ores/ml, insects started to die from 5-7 days, and were covered with mycelia andspores in 24-28 days at 25"C, while the insect did not show visible symptoms even after 50 days at 4'C. Theinsect injected with 5 pl of spore solution (3X l0'~-10s~p oreslml) died within 30-98 and 38-218 hours at25$^{\circ}$C and 4"C, respectively. About 3 days (60 hours) after the injection with a concentration of 3 x lo9 spores1ml, at the point of the insect's death, lots of proteins started to disappear '||'&'||' the hemolymph, fat body and carcaseat 25'C. Esterase activity in the tissues was gone suddenly after that time. Six days after the spray, manyprotein and esterase bands were lost in the hemolymph, but not those in the fat body and carcase. When thefungi growing in the host were exposed in the air, they put energy for spore production, while numerous longand thin mycelia branched out from the host body in the soil.e host body in the soil.

The purpose of this study was to investigate the scope of standard color perception for Americans and to compare the differences in color perception between Korean and American undergraduates. Sixty male and fifty-one female American undergraduates were selected as a random sample. Color perception was tested with the naked eyes. Minolta Chroma Meter CR 300 was used for physical measurement of the color. Based on the objective of this study and the data generated the following results were drawn: 1) We found no distinctive difference in color perception by different eye colors. 2) Color perception of American undergraduates is largely classified into four different groups: simple group includes Yellow, Green, Blue, White, Gray, and Black, X(-axis)group includes Yellow Red, Y(-axis)group includes Blue Green, Purple, complex group includes Yellow Red, Purple Blue. 3) The differences in color perception between the two undergraduate groups were found to be significant with four colors: Yellow Red, Green, Blue, and Purple. 4) There is a wide difference between the values of standard color and inn percept color. When undergraduates in both countries were compared, it turned out that Korean students were more accurate than Americans in color perception. 5) American students perceived Red, Yellow, and Green colors relatively correctly, but showed an extremely low degree of accuracy in Blue and Purple Blue color perception.
