  • This research is to observe background of origination and process of changing style for men's suits and also to observe the root of aes-thetics which has made the changing style be maintained for nearly 200 years. The aesthetic characteristics are 1)The revival of the Neo-Classicism beauty in the 18th century could be regarded as the root of incipient style of the modern men's suits design. And the cutters recreated ancient nude hero which was an object of envy at that time and also reproduced men's suits through modifying the existed suits to make the ancientnude conform with the sewing regulations in order to describe and convey the perfect image of gender,. 2) The cutter who pursued merit of the classicismic aesthetics in the late 18th cen-tury artistically upgraded English rough country coat to keep pace with Nordic coat style of netherland Russia Germany while in constrast with the coat style mode which was in fashion in France and Italy then And also they changed the English country coat to a noble natural clothing structure in relation to ancient sculpture to keep the English tradition. 3) Im the 18th century Neo-Classicism art emphasized transparent and monochromatic beauty and thus color was limitedly used. In the use of the limited color however ancient aesthetical simple purity was well described within the more realistic outline. In those days the cutter who admired the English neo-Classicism removed color-luster and preferred colorless finished dimly and transparently. And thus color of the men's suits become to be also dim colored in los brightness. This means that it did not express pure beauty but brought such effect of the Classicism beauty that the nude itself was figured out.

  • The purpose of this study is to expression pattern of melanogenesis associate genes on cultured melanocyte layer cells in Korean Brindle Cattle(Dark, Brindle and Yellow) were analyzed to evaluate the effects of sex hormones on the control of melanogenesis pathways. Korean Brindle Cattle(Dark, Brindle and Yellow) melanocyte in the skin cells was collected. after the addition of estrogen and testosterone, the culture was analyzed for expression of cell activity and melanin genes for 72 hours. For the analysis of estrogen in different coat color other than the melanogenesis-related genes it is increasingly yellow showed low expression. in particular, the cells of the brindle coat color is low active and expression of genes. However, the testosterone was low, the expression of cell activity inhibiting MMP-2. the expression of melanin genes actually showed a tendency to increase gradually, which is testosterone compared with the estrogen to be considered that affect the skin cell layer brindle coat color. In this study, stimulation with estrogen triggered the inhibition of MC1R of the melanocyte in brindle coat color, but testosterone is induced MC1R in melanocyte. Therefore, considered the eumelanin or phaeomelanin activation are controlled caused by differential expression of sex hormones on melanocyte in Korean Brindle Cattle.

  • In this study, ${\beta}$-carotene concentrations was determined in soybean cultivar according to seed size, usage, seed coat color and cotyledon color as well as the process of seed germination. The total average concentration of ${\beta}$-carotene was $6.6{\mu}g/g$ in soybean seed, $33.3{\mu}g/g$ in soybean sprout. According to seed size, the total ${\beta}$-carotene concentration of soybean was $6.9{\mu}g/g$ in large soybean seed, $6.7{\mu}g/g$ in medium soybean seed, and $6.31{\mu}g/g$ in small soybean seed. In soybean sprout, the total ${\beta}$-carotene concentration was $21.4{\mu}g/g$ in large soybean sprout, $30.5{\mu}g/g$ in medium soybean sprout, and $43.5{\mu}g/g$ in small soybean sprout. According to the utilization of seed, the total ${\beta}$-carotene concentration of soybean seed was $7.2{\mu}g/g$ in cooked with rice soybean seed, $6.1{\mu}g/g$ in paste and curd soybean seed, and $6.3{\mu}g/g$ in sprout soybean seed. In soybean sprout, the total ${\beta}$-carotene concentration was $25.9{\mu}g/g$ in cooked with rice soybean sprout, $32.4{\mu}g/g$ in paste and curd soybean sprout, and $41.9{\mu}g/g$ in sprout soybean sprout. When comparison with seed coat color, the total ${\beta}$-carotene concentration of soybean with brown seed coat ($8.8{\mu}g/g$) was slightly higher than those of soybean with yellow ($6.1{\mu}g/g$). In soybean sprout, the total ${\beta}$-carotene concentration was $21.8{\mu}g/g$ in black seed coat sprout, $38.7{\mu}g/g$ in brown seed coat sprout, $34.1{\mu}g/g$ in green seed coat sprout, $39.5{\mu}g/g$ in yellow seed coat sprout, and $30.5{\mu}g/g$ in mottle seed coat sprout. The results of this study suggested the functional characteristics of soybean through quantitative analysis of ${\beta}$-carotene.

  • 본 연구는 제주마의 기본모색 분류체계와 유전 변이간의 관계를 확인하기 위해 수행되었다. pyrosequencing 방법을 이용하여 melanocortin receptor 1 (MC1R)과 agouti signaling protein (ASIP) 유전자의 변이를 분석하였다. MC1R은 g.901C>T 염기치환을 분석하였고, ASIP는 11-bp 결실돌연변이를 분석하였다. 가라마필은 MC1R에서는 $E^+$/- ($E^+/E^+$ or $E^+/E^e$), ASIP에서는 $A^a/A^a$ 유전자형이 나타났다. 유마 마필에서는 MC1R은 $E^+$/- 그리고 ASIP는 $A^A$/- 유전자형이 나타났다. 반면에 적다 마필에서 MC1R은 $E^e/E^e$ 유전자형만이 나타났으며, ASIP에서는 모든 조합의 유전자형이 나타났다. 가라모색과 유마모색은 MC1R에서 적어도 1개의 $E^+$ 우성대립유전자를 갖고 있어야하며, 적다모색에서는 동형열성대립유전자인 $E^e/E^e$ 유전자형을 가져야 한다. 이는 ASIP 유전자형 분포와 관계없이 MC1R 유전자형에 의해 가라/유마모색과 적다모색을 결정하는 것이다. 또한 MC1R은 $E^+$/- 그리고 ASIP은 우성대립유전자인 $A^A$/-를 갖는 마필은 유마모색을 나타내는데 이는 ASIP은 우성대립유전자인 $A^A$에 의해 사지를 제외한 부분에서 흑모색발현을 억제하는 것으로 추정된다. 가계분석에서는 제주마와 더러브렛간에 교배로 생산된 $F_1$ 자마의 기본모색 양상과 MC1R 및 ASIP 유전자형 분포와의 관계에 대해 일정한 결과를 보여주고 있다. 본 결과는 모색에 대한 표현형과 유전양상 간의 관계를 보여주고 있으며, 제주마의 분자육종을 위한 중요한 정보를 제공할 수 있을 것으로 사료된다.

  • 포유동물에서 KIT 유전자는 우성 백색의 모색발현에 관여하는 후보유전자로서 mast/stem cell growth factor receptor를 암호화하는 것으로 알려져 있다. 본 연구에서는 한반도에서 서식하고 있는 야생멧돼지의 모색발현에 있어서 KIT 유전자의 유전적 변이를 확인하기 위하여 PCR- RFLP와 염기서열 분석을 수행하여 유전적 변이를 관찰하였다. 멧돼지 KIT 유전자의 exon17- intron 17 경계부위에 대한 NlaⅢ-RFLP 결과 splicing mutation이 없고, exon 19 상에서의 SNP C2678T에 대한 AciⅠ-RFLP 결과 역시 백색 품종들의 유전자형과는 다르게 나타났다. 이상의 결과는 멧돼지 집단 내 교잡에 의해 백모색의 자손이 출현하지 않음을 의미한다. 또한 exon 19과 exon 20에서 새로운 SNP들이 확인되었으며 이들 중 exon 20에서의 SNP A2760G는 아미노산의 변화(iso-leucine→valine)를 초래할 수 있으나 모색 발현과의 연관은 확인할 수 없었다. 돼지 KIT 유전자의 exon 19, 20과 intron 19 상에서의 새로 발견된 SNP와 splicing mutation의 존재 여부 등은 품종특이적인 양상으로 확인되었고, 이 같은 결과는 돼지에서 백색 모색 발현을 설명할 수 있는 좋은 자료가 될 것으로 사료된다.

  • The objective of the present studies was to develop and validate a system for isolation, purification and extended culture of pigment-producing cells in alpaca skin (melanocytes) responsible for coat color and to determine the effect of alpha melanocyte stimulating hormone treatment on mRNA expression for the melanocortin 1 receptor, a key gene involved in coat color regulation in other species. Skin punch biopsies were harvested from the dorsal region of 1-3 yr old alpacas and three different enzyme digestion methods were evaluated for effects on yield of viable cells and attachment in vitro. Greatest cell yields and attachment were obtained following dispersion with dispase II relative to trypsin and trypsin-EDTA treatment. Culture of cells in medium supplemented with basic fibroblast growth factor, bovine pituitary extract, hydrocortisone, insulin, 12-O-tetradecanolphorbol-13-acetate and cholera toxin yielded highly pure populations of melanocytes by passage 3 as confirmed by detection of tyrosinase activity and immunocytochemical localization of melanocyte markers including tyrosinase, S-100 and micropthalmia-associated transcription factor. Abundance of mRNA for tyrosinase, a key enzyme in melanocyte pigment production, was maintained through 10 passages showing preservation of melanocyte phenotypic characteristics with extended culture. To determine hormonal responsiveness of cultured melanocytes and investigate regulation of melanocortin 1 receptor expression, cultured melanocytes were treated with increasing concentrations of ${\alpha}$-melanocyte stimulating hormone. Treatment with ${\alpha}$-melanocyte stimulating hormone increased melanocortin receptor 1 mRNA in a dose dependent fashion. The results demonstrated culture of pure populations of alpaca melanocytes to 10 passages and illustrate the potential utility of such cells for studies of intrinsic and extrinsic regulation of genes controlling pigmentation and coat color in fiber-producing species.

  • The purpose of this pilot study was to examine the effect of tongue color change due to food ingestion on tongue diagnosis by both Korean Medicine doctors and digital tongue diagnosis system. In order to obtain objective and quantitative data, we used digital camera to collect the data. Prior to our investigation, we conducted a brief survey of 26 Korean Medicine doctors and found out that tongue diagnosis is frequently used and food-stained tongue could be commonly observed in clinics. Depending on their color, viscosity, and amount of intake, various foods caused stains with different colors and thicknesses. Also, duration and amount of food stain on tongue were different from person to person. Since coffee-stained tongue was the most frequently observed one in clinics according to the survey, we used coffee to evaluate the effect of food-stained tongue on tongue diagnosis. Korean Medicine doctors tended to interpret coffee-stained tongue as having yellow tongue coat but their judgement on tongue body color did not differ in spite of the coffee stains. Meanwhile, tongue diagnosis system algorithm tended to judge coffee-stained tongue as having normal but yellowish tongue coat and reddish tongue body. Altogether, food color on tongue can influence tongue diagnosis outcomes. Further research is needed in order to develop more efficient tongue diagnosis algorithm and digital medical service system.

  • Objective: This study aimed to investigate the significant single nucleotide polymorphisms (SNPs) and genes associated with nine reproduction and morphological traits in three breed populations of Chinese goats. Methods: The genome-wide association of nine reproduction and morphological traits (litter size, nipple number, wattle, skin color, coat color, black dorsal line, beard, beard length, and hind leg hair) were analyzed in three Chinese native goat breeds (n = 336) using an Illumina Goat SNP50 Beadchip. Results: A total of 17 genome-wide or chromosome-wide significant SNPs associated with one reproduction trait (litter size) and six morphological traits (wattle, coat color, black dorsal line, beard, beard length, and hind leg hair) were identified in three Chinese native goat breeds, and the candidate genes were annotated. The significant SNPs and corresponding putative candidate genes for each trait are as follows: two SNPs located on chromosomes 6 (CSN3) and 24 (TCF4) for litter size trait; two SNPs located on chromosome 9 (KATNA1) and 1 (UBASH3A) for wattle trait; three SNPs located on chromosome 26 (SORCS3), 24 (DYM), and 20 (PDE4D) for coat color trait; two SNPs located on chromosome 18 (TCF25) and 15 (CLMP) for black dorsal line trait; four SNPs located on chromosome 8, 2 (PAX3), 5 (PIK3C2G), and 28 (PLA2G12B and OIT3) for beard trait; one SNP located on chromosome 18 (KCNG4) for beard length trait; three SNPs located on chromosome 17 (GLRB and GRIA2), 28 (PGBD5), and 4 for hind leg hair trait. In contrast, there were no SNPs identified for nipple number and skin color. Conclusion: The significant SNPs or genes identified in this study provided novel insights into the genetic mechanism underlying important reproduction and morphological traits of three local goat breeds in Southern China as well as further potential applications for breeding goats.

  • 소의 Extension (E), Agouti (A) 유전자형과 모색유전양상의 연관관계를 이해하기 위해, 한우와 제주흑우(JBC), 이들 사이에서 생산된 교배후손에서 melanocortin-1 receptor (MC1R)과 agouti signaling protein (ASIP)의 유전자형을 분석하였다. 흑모색의 JBC에서는 세 가지 MC1R 대립인자들($E^D$, $E^+$, e)이 모두 발견되었다. JBC 집단은 한우에서 우점적으로 나타나는 열성동형접합자(e/e)가 발견되지 않았다. 반면, MC1R $E^+$/e 한우는 흑모색이 아닌 갈색이나 적색의 모색을 나타내었다. ASIP 유전자에서, 한우에서는 L1-BT 전위인자의 삽입/결실에 의해 세 가지 유전자형(A/A, A/$A^{Br}$, $A^{Br}/A^{Br}$)이 모두 관찰되었다. JBC 집단에서는 ASIP $A^{Br}$ 대립인자가 드물게 관찰되고, ASIP $A^{Br}/A^{Br}$ 동형접합인 개체들은 발견되지 않았다. ASIP $A^{Br}$ 대립인자를 보유하더라도 한우와 JBC, 이들의 교배후손에서도 agouti-유사 얼룩무늬 모색은 발견되지 않았다. 교배후손의 모색은 Agouti 유전자형과는 무관하고, Extension 유전자형과 직접적으로 연관되어 황-갈색(e/e)과 암-갈/흑색($E^+$/e)으로만 구분되었다. ASIP 유전자형은 아마도 한우 또는 교배 후손에서 모색의 발달에 영향이 없는 것으로 추정된다. 본 연구 결과는 한우, 제주흑우, 이들의 교배후손에서 MC1R 유전자형이 모색 표현형을 결정하며, ASIP 유전자형은 모색의 변이에는 핵심적인 역할을 수행하지 않는다는 것을 시사한다.
