Black froak coat, white shirts, top hat and cane has been the symbol of gentlemen in 19th and early of 20th century. The pattern invented by Savile Row in London prevailed whole England. Such a pattern has been the standard form for two hundred years all over the word, although it was replaced with a functionalism which developed in Italy and America at the end of 20th century. The clothes of gentlemen was developed by several factors ; English people respect a tradition. The clothes was practical, since the weather in England was bad. The success of Industrial Revolution made England wealthy. Various special clothes in sports, for example, riding, criket, golf and tennis also contribute the modern gentlemen clothes with advance tailoring technique. The change of gentlemenship with social environment, from Regency dandy, Romantic gentlemen to Muscular Christianity, was studied. Idial gentlemenship and development its clothes which is now the standard of modern men's wear also studied.

Soybean has been cultivated in China for 5,000 years. The soybean cyst neamtode (SCN), Heterodra glycines, was recongnized in Northeastern China in 1899. Currently, it is known to occur in 12 provinces. The biology of SCN was investigated in several provinces. Six races of SCN were identified (race 1, 2, 3, 4, 5 and 7). About f10,000 soybean germplasm lines were evaluated for their resistance to race 1, 3, 4 and 5 of SCN. At least two black-seeded cultivars are resistant to all four races. Several tolerant soybean cultivars with yellow seed coat were released and are in production. Additional resistant cultivars are being developed. Nematicides were not applied in production Potential biocontrol agents and related aspects are being investigated.

Carbon black, activated carbon and carbon nanotube have been used as supporting materials for precious metal catalysts used in fuel cell electrodes. One-step flame synthesis method is used to coat 2-5nm Pt dots on flame-generated carbon particles. By adjusting flame temperature, gas flow rates and resident time of particles in flame, we can obtain Pt/C nano catalyst-support composite particles. Additional injection of hydrogen gas facilitates pyrolysis of Pt precursor in flame. The size of as-incepted Pt dots increases along the flame due to longer resident time and sintering in high temperature flame. Surface coverage and dispersion of the Pt dots is varied at different sampling heights and confirmed by Transmission electron microscopy (TEM), Energy-dispersive spectra (EDS) and X-ray diffraction (XRD). Crystalinity and surface bonding groups of carbon are investigated through X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy.

The National Agrobiodiversity Center (NAS, RDA, Republic of Korea) has continually collected new valuable genetic resources. In this study, we regenerated conserved kidney bean (Phaseolus vulgaris L.) germplasm which couldn't be available because of seed quantity and quality, and we also surveyed their morphological characters for the sustainable utilization. A total of 431 kidney bean accessions were regenerated and 18 morphological traits were surveyed according to the characterization guideline of RDA Genebank. Among the surveyed traits, flowering time ranged from May 23 to September 4 and 73.8% of tested accessions were mainly flowering in June. The maturity time ranged from July 1 to October 15 and main flowering time was July (91.4%). For plant type, 270 accs (62.6%) were climbing type followed by medium type of 86 accs (20.0%) and dwarf type of 65 accs (15.1%). The seed coat colors were various; yellow (34.6%), white (22.3%), brown (17.9%), red (10.7%), black (5.8%), violet (11%), pink (1.4%), navy (0.9%). Principal component analysis indicated that five principal components (PCs) with Eigen values >1 accounted for more than 65.8% variability. The first PC was more related to growth habits such as growth type, flowering time, and plant type. The second and third PCs showed higher values of the pigment characters such as seed coat color, flower color, and pod color. In fourth and fifty PCs, there were the higher positive values of the pod shapes. Our results provided insight into the characteristics kidney beans, thus the utilization basis of kidney beans might be elevated for bio-industry.

This study is focused on the man's costumes of Sadangpae(the troupe of performers) shown in Gamrotaenghwa (감로탱화) during the late Chosun dynasty. Originally Gamrotaenghwa was used as a painting for a Buddhist praying ceremony, 또Young-ga-cheon-do-je(영가천도제). It shows us the lives of the commoners in those days. Gamrotaenghwa reflects the changes of costume style in the late Chosun period. The early styles of po(포, coat) for male performers in the 17th century were changeui(창의) and dopo(도포), which had the front panels(seop) overlapped deeply and sleeves that got wider as time passed. After the 18th century, Male performers wore a simpler coat such as sochangeui(소창의), which had narrow sleeves and long slits on the both sides. Especially the coats of acrobats were fastened on the center front with buttons. Heuklip(흑립: black hat), somoja(소모자: small cap) and jeonlip(전립: wool hat) were used as hats for the male performers. Originally, heuklip was the hat that represented the noble status: yangban(양반). However, it was popularized among the commoners in the late Chosun period. As time passed on, the heuklip became more popular and its shape also changed. Somoja and jeonlip were shown throughout the entire Gamrotaenghwa. Unlike heuklip, those were common hats for Sadangpae. The costumes of entertainers shown in Gamrotaenghwa were very similar to those of the commoners. However, it seems that there were some differences of the costumes depending on the roles they performed.

Growth and seed productivity of black soybean (cv. Cheongja-3ho) sown on four different dates were investigated in paddy fields in the southern region to cope with climate change, trends in consumption of soy foods, and the spread of double cropping region. Sowing date of black soybean showed a significant correlation with above-ground growth, seed yield, useful components, etc. When sown in May, the above-ground part was plentiful, while seed yield significantly decreased. On the other hand, when sown in June and July, reproductive growth was vigorous resulting in high seed yield, exceeding 200 kg/10a, and pod injury and seed coat cracking were reduced. Furtherm ore, the isoflavone content of seed increased significantly as the sowing date was delayed. These results suggests that sowing from early June to early July is appropriate. Nevertheless, late June sowing oppears the m ost appropriate for black soybeans in the southern paddy fields, in order to avoid a risk of overlapping with sowing dates of winter crops in the double cropping.

An investigation was made to find regional differences and seed characteristics of buckwheats collected from 36 areas in Chungnam province in 1984, and the results obtained are summarized as follows; 1. Grain types of the collected buckwheats were classified as winged, semi-winged and common types. All collections were on the average composed of 50.1 % of common grain types, 26.8 % of semi-winged type and 23.1 % of winged types, respectively. However, there was a great regional difference in components of each grain type among collections. 2. The mean 1000 grain weight was 24.9 gr. The regional differences in 1000 grain weight showed that a collection (collection no. 30) from Susan was 17.4 gr and a collection (collection. no. 16) from Suchon was 31.9 gr. There wasn't any significant relationship between grain types component and 1000 grain weight. 3. Germination of seeds was accelerated as temperature goes up from $5^{\circ}C$ to $30^{\circ}C$. However, interesting germination pattern was observed. That is, seeds from Suchon (collection no. 16), Hongsung (collection no. 23), Cheonweon(collection no. 35), and Yesan (collection no. 27) showed abrupt decrease of germination rate at the temperature of $15^{\circ}C$. The seeds collected from Suchon (collection no. 29), Dangjin (collection no. 32) and from Chungyang (collection no. 21) showed decrease of germination rate at $25^{\circ}C$. These seeds showed, however, the increase of germination percentage at temperature higher than $15^{\circ}C$ and $25^{\circ}C$, respectively. The germination rate for the most collections at $5^{\circ}C$ was less than 10%. However, seeds from Asan (collection no. 33) and Daeduk (collection no. 3) showed 20% and 30% of germination rate at $5^{\circ}C$, respectively. 4. Color of seed coat could be classified into two maj or colors, dark and dark brown. Based on the seed coat color and grain types, all the collections could be classified into the following six categories: winged-black, semi-winged-black, common-black, winged-dark brown, semi-winged dark brown and common-dark brown. The different light absorption rate was found within the UV light zone (190-390 nm) depending upon the two different major seed coat color.

The objective of this study was to investigate the polyphenolic compounds found in different parts of red and black adzuki beans and to determine the contribution of polyphenolic compounds to the antioxidant properties of adzuki beans. Total polyphenolic and proanthocyanidin contents were studied and their antioxidant activities were determined by ferric reducing antioxidant power, 1,1-diphenyl-2-picrylhydrazyl (DPPH), and 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt assay. The highest total polyphenolic content was found in seed coats (26.1~33.9 mg/g), followed by whole beans (6.9~8.0 mg/g) and dehulled beans (3.3~3.4 mg/g). The highest total proanthocyanidin content was also found in seed coat with 26.5~30.7 mg/g. Moreover, seed coats exhibited the highest antioxidant activity regardless of analytical methods. Antioxidant activity was positively and significantly correlated with total polyphenolic content with the exception of dehulled beans, in which there was no correlation with total polyphenolic content. In particular, the highest correlation was found between DPPH and total polyphenolic content (r=0.945, P<0.01) in whole beans.

Rat pheochromocytoma cells (PC12) and mice were utilized as in vitro and in vivo models to determine the neuroprotective effects of a 70% acetone extract of black soybean seed coat (BSSCE). BSSCE showed higher total phenolic contents than other extracts. Intracellular reactive oxygen species accumulation from $H_2O_2$ treatment of PC12 cells was significantly reduced when BSSCE was present in the media compared to PC12 cells treated with $H_2O_2$ only. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium-bromide (MTT) reduction assay and lactate dehydrogenase assay also showed significantly increased protective effects in PC12 cells. In addition, BSSCE improved the in vivo cognitive ability against amyloid beta peptide-induced neuronal deficits.

The aim of this study is to investigate the traditional manufacturing technique of lacquering by comparing and analyzing materials used for wooden lacquerware artifacts with focus on the Joseon dynasty Eugye, and to apply the manufacturing technique to the conservation treatment of the lacquerware. artifacts. This study conducted the documentary survey focusing on "Yongjo Jeongsun Queen Consort Garye Dogam Eugye",and "Jeongjo Gukjang Dogam Eugye." The royal lacquering is roughly classified into three categories-scarlet lacquering, quality black lacquering, and terra rosa lacquering- according to materials used for lacquerware. The bean flour was mostly used for under lacquering of the articles which was offered to the king and in case of other articles, bean flour was used mixed with bone ashes. In some cases, burned pine soot was added to under lacquering. Japanese scarlet lacquering was applied by mixing maechil-main coat, in inverted commas- with Japenese scarlet after lacquering jeonchil-base coat, in inverted commas-. In case of Chinese scarlet lacquering, part of terra rosa was used mixed with red clay. For quality black lacquering, basically jeonchil and maechil were used, but sometimes part of burned pine soot was added. In addition, terra rosa lacquering was applied by basically using terra rosa mixed with red clay. Lastly, gloss was given by using perilla oil. It is expected that the traditional materials and technique examined through both documentary and relic research will contribute to advanced result of the conservation treatment of wooden lacqueringware artifacts.
