The relationship between Tang and Silla was closer than other countries and districts of North-east Asia. At Tang Dynasty, Dispatching the formal envoy between them had 160times by record in the hitory chronicle(which has 104 times before the middle 8th. Ad century , then 56times). The traffic between Tand and Silla based on seaway, because the relationships of GaoLi, Silla and Baiji fell foul of each other at 625 AD, GalLi had blocked the land way from Silla to Tand. The marine trade , development in political association bwtween Tand and Silla, was occupied by personal marine trade gradually which accompanied with the Tang empire.

본 논문은 흑백 영문 명함 영상에서 개별 문자 추출에 관한 연구이다. 20개의 원본 명함 영상을 3배로 축소하고, 가로 세로 스미어링 기법을 이용하여 문자간의 여백을 제거하여, 문자 영역의 추출을 용이하게 하였다. 그리고, 윤곽선 추적 기법을 이용하여 문자열과 개별 문자를 추출하였다. 실험결과에서는 윤곽선 추적 알고리즘을 이용한 명함의 개별 문자 추출이 효과적인 것을 보인다.

The purpose of this study was to identify and to classify the names of costume colors of women of Silla. The results of this study can be summarized as follows; Until now scholars and researchers interpreted nine colors in Sam Guk Sa Ki as nine colors explained in the dictionaries. However, term, nine colors in the contexts did not refer to the literary meaning of nine colors such as blue, red, yellow, white, black, green, purple, pink, and navy blue as explained in the dictionaries. 'Nine colors' of Silla were women's costume colors which were specified in the royal edict in the texts. Thus, 'nine colors' of Silla had a specific meaning rather than literary meaning. 'Nine colors' of Silla women's costume were identified as red( ), yellow(黃), purple(紫), purplish pink(紫粉), gold powder(金屑), pink(紅), yellow powder(黃屑), dark pink(緋) and dark purple(滅紫). These 'nine colors' were actually prohibited colors in women's costume in the royal edict. Women from true bone, the highest class, were prohibited the use of tow colors of red and yellow out of nine colors. While women from four du pum and common class were forbidden the use of nine colors out of total of nine colors. Kinds and numbers of colors of costume were used as a means of differentiating the social class and rank of women in Silla. Also it was found that women of Silla favored red purple, pink tones and yellow color in their costume and these colors were fashionable colors among women of Silla. These fashionable costume colors of Silla women seems to be influenced by fashions of women of T'ang dynasty of China. Red, purple, pink, yellow and green were favorite colors of women of T'ang dynasty of China.

The whitening effect, tyrosinase inhibition, and cytotoxicity of neoagarotetraose were measured after its purification from hydrolyzed agar by gel filtration chromatography. In melanoma B16F10 cells, the melanin content of neoagarotetraose-treated cells was the same as that treated by kojic acid or arbutin. In addition, tyrosinase of melanoma cells was strongly inhibited by neoagarotetraose at a concentration of $1{\mu}g/ml$ and similarly inhibited at 10 and $100{\mu}g/ml$ compared with those by arbutin or kojic acid. The activity of mushroom tyrosinase showed a 38% inhibition by neoagarotetraose at $1{\mu}g/ml$, and this inhibitory effect was more efficient than that by kojic acid. Neoagarotetraose revealed a similar $IC_{50}$ (50% inhibition concentration) value for mushroom tyrosinase as that by kojic acid. These data suggest that the neoagarotetraose generated from agar by recombinant $\beta$-agarase might be a good candidate as a cosmetic additive for the whitening effect.

Purpose: This paper examined the relationship between knowledge differences of maternal oral health and of relevant demographic variables. Methods: Participants included 239 pregnant women who were recruited from Women's Hospital located in B city who agreed to participate in this study. The data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation analysis using the SPSS 21.0 program. Results: Maternal knowledge of oral health was moderate level ($10.22{\pm}2.36$). Scores of maternal knowledge of oral health were different according to age, education, occupation, parity, and dental care experience in pregnancy. Level of oral healthcare knowledge was weakly related to age and education. Conclusion: Consequently, it is necessary to encourage pregnant women to take part in oral health education program during antenatal care.

The gene for a L-aspartate $\beta-decarboxylase$ (ADC) from Enterococcus faecalis was cloned and sequenced. The gene comprised an open reading frame of 1,611 base pairs, which encodes a protein of 58,960 Da consisting of 536 amino acid residues. The gene was subcloned into an expression plasmid for overexpression of the ADC. The recombinant ADC was produced using E. coli as the host and purified to homogeneity. Our result showed that the ADC may be obtained from bacteria known nucleotide sequence. Thus, we suggest that high value L-alanine might be produced by low value aspartate.
