Objective: Pigment production and distribution are controlled through multiple proteins, resulting in different coat color phenotypes of sheep. Methods: The expression distribution of vimentin (VIM) and transthyretin (TTR) in white and black sheep skins was detected by liquid chromatography-electrospray ionization tandem MS (LC-ESI-MS/MS), gene ontology (GO) statistics, immunohistochemistry, Western blot, and quantitative real time polymerase chain reaction (qRT-PCR) to evaluate their role in the coat color formation of sheep. Results: LC-ESI-MS/MS results showed VIM and TTR proteins in white and black skin tissues of sheep. Meanwhile, GO functional annotation analysis suggested that VIM and TTR proteins were mainly concentrated in cellular components and biological process, respectively. Further research confirmed that VIM and TTR proteins were expressed at significantly higher levels in black sheep skins than in white sheep skins by Western blot, respectively. Immunohistochemistry notably detected VIM and TTR in hair follicle, dermal papilla, and outer root sheath of white and black sheep skins. qRT-PCR results also revealed that the expression of VIM and TTR mRNAs was higher in black sheep skins than in white sheep skins. Conclusion: The expression of VIM and TTR were higher in black sheep skins than in white sheep skins and the transcription and translation were unanimous in this study. VIM and TTR proteins were expressed in hair follicles of white and black sheep skins. These results suggested that VIM and TTR were involved in the coat color formation of sheep.

Soybean seeds are important sources of non-nutritive health promoting metabolites. The contents of these metabolites are affected by both genetic and environmental factors. In the present study, the contents of five common isoflavones including daidzin, genistin, glycitin, malonyldaidzin, and malonylgenistin were analyzed in 72 soybeans of different seed coat colors, diversity, and of different origins including China (22), Japan (9), USA (12), India (4), and Korea (25). The average total isoflavone content (TIC) was maximum in Indian soybeans (3302.36 ㎍/g) and minimum in Chinese landraces (1214.95 ㎍/g). The Korean landraces had higher average TIC (2148.05 ㎍/g) than the USA genetic materials (1580.23 ㎍/g) and Japanese landraces (1485.99 ㎍/g). The content of malonylgenistin was in the range of 54.31 - 2385.68 ㎍/g in the entire population, and was the most abundant isoflavone irrespective of origin although there was content variation among individual soybeans. Besides, glycitin was the least concentrated isoflavone, and its content ranged from 0.00 to 79.79 ㎍/g. With respect to seed coat color, green soybeans from all countries displayed the maximum malonylgenistin and TIC contents. Exceptions were those of Korean and Indian origins where black and yellowish-green soybeans presented the highest malonylgenistin and TIC contents, respectively. In multivariate analysis, 92.72% of the variance was explained by the first two principal components, and the soybeans were grouped in to three clusters based on isoflavone contents. Overall, our findings signify the importance of seed coat color and origin as discriminant parameters, and provide wide spectrum of routes for breeding soybean cultivars.

Wasabies showing mosaic symptoms were collected and extracted for virus purification. Tobacco mosaic virus (TMV) was identified as causal agent by electron microscopy and nucleic acid and coat protein analyses. TMV strains were determined by enzyme-linked immunosorbent assay (ELISA). TMV was identified as W and C strain in wasabi. The results of host reaction indicated that this virus induced local lesions on Nicotiana tabacum cv. Bright Yellow and N. glutinosa, leaf spots on Chenopodium amaranticolor and mosaic symptoms on wasabi. Rot shape virus particles were observed and was about 300 nm in length. About 6.5 kb single RNA molecule was observed from extracted viral RNA sample and 26 KDa coat protein was detected in denatured acrylamide gel. Infection ratio of TMV was 8% for the first cultivation year, but was 22% for the second year when TMV-W antiserum was used. The results of this experiment showed that infection ratios of both TMV-W and TMV-C strains were higher compared to that of TMV-P strain.

The residual stresses in the interface region of the Thermal Barrier Coating (TBC)/Thermally Grown Oxide (TGO)/Bond Coat (BC) were calculated on the TBC-coated superalloy samples using a Finite Element Method (FEM). It was found that the stress distribution of the interface boundary was dependent upon mainly the geometrical shape or its aspect ratio and the thickness of TGO layer, which was formed by growth and swelling behavior of oxide layer. Maximum compressive residual stress in the TBC/TGO interface is higher than that of the TGO/bond coat interface, and the tensile stress had nothing to do with change of an aspect ratio. The compressive residual stresses in the TBC/TGO and TGO/bond coat interface region increased gradually with the TGO growth.

During the 3C(B.C.) and 2C(A.D.), there were large influx of variety of arts to Jin and Han dynasty such as music, dancing, and at performing from neighboring countries. It made a tremendous impact on the development of dancing an in Han dynasty. On the other hand, Kokurye people had also enjoyed their own singing and dancing culture (styles) for a long time. Han and Kokurye's dancing costumes were studied based on artifacts (data) such as wall paintings, clay doll, and other small paintings all from tombs in Han and Kokurye. A similarity was found between two dynasties' dancing costume, since both had tong sleeve dresses. However, the further detailed study showed that one can't simply say both are in the same style. For example, the dress in Han dynasty had a long length style of coat(深衣) covering all the way to feet, and there were round neckline coat(團領) and long Jacket(장유). In contrast, that of Kokurye had a shorter length in coat(直領) covering only up to calf of the leg or long jacket(장유).

The cDNA of tobacco mosaic virus-pepper strain (TMV-P) coat protein (CP) genes were introduced into tobacco plants (Nicotiana tabacum cv. Samsun nn) using a binary Ti plasmid vector of Agrobacterium tumefaciens. these cDNAs introduced into tobacco plants were detected by polymerase chain reaction. Symptom development was distinctly suppressed in the transgenic plant introduced buy sense CP cDNA when the plant was inoculated with TMV-P, while in transgenic tobacco plants of antisense CP gene, symptom development was not suppressed as in non-transgenic plants. TMV-P concentration in the sense CP transgenic tobacco plant was decreased to 1/14 of the concentration in non-transgenic plants. Expression of the kanamycin resistance gene of these transgenic plants could be detected in the progeny.

Bacterial virus f2 and its RNA were examined to elucidate the mode of ozone utilizing sucrose density gradient analysis and electtron microscopic techniques. the inactivation kinetics of the virus f2 by ozonation showed that the viruses were inactivated during the first 5 sec of the reaction and were further inactivated at a slower rate during the next 10 min at 0.09 and 0.8mg/l ozone concentrations. The virus coat was broken by ozonation into many pieces of protein subunits and the adsorption of the viruses to the host pili was inversely related to the extent of the breakage of the virus. The viral RNA was released from the virus particles during ozone, but ozone inactivation of the RNA enclosed in the protein coat could not ruled out the possibility that the RNA was secondarily sheared by a reaction with the broken coat protein.

This research was made to suggest a functional and fitted prototype of swallow-tailed coat for sports dance. We established the basic posture of standard dance from literature investigations, and grasped the changes of the body side-surface by motions through the gypsum-experiments with a man in twenty. The unfolded gypsum shells were overlapped on the basic swallow-tailed coats pattern drafted by their size of experimenter. From our results through analysis, our pattern of the swallow-tailed coats for sports dance was designed considering their functional and structural character. In case of upper body with the greatly increased shoulder width of garment and with the decreased front. When moving, owing to the rising of the armpit point, the side-line becomes longer with the shoulder length decreased greatly. In case of sleeves, the length of sleeves back increased greatly by the arm-bending motions while sleeve height becomes lowered.
