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.

Several days after culture, the parts around suspensor turned brown. In about 10 days the embryo started to form protocorm sending out hairs through seed coat. Around 20 days after culture, most of the protocorms emerged out of seed coat and some of them began to take green color. When observed two months after culture, the protocorn took the characteristic top-shape feature.

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.

This study was undertaken to reveal the relationship between genetic variations and the basic coat color classification system in Jeju horses. Genetic variations of the melanocortinreceptor 1 (MC1R) and agouti signaling protein (ASIP) genes were investigated using pyrosequencing technique. A nucleotide substitution mutation for MC1R g.901C>T and an ASIP 11-bp deletion mutation were screened. Black horses had MC1R $E^+$/- ($E^+/E^+$ or $E^+/E^e$) and ASIP $A^a/A^a$ genotypes. In contrast, chestnut horse genotypes were MC1R $E^e/E^e$ and ASIP -/-. Thus, black and bay horses have at least one dominant MC1R allele, $E^+$, whereas chestnut horses have homozygous recessive alleles $E^e/E^e$. This suggests that the MC1R genotypes determine chestnut or black/bay coat color, regardless of the genotype distribution of ASIP. In addition, the horses with MC1R $E^+$/- and a dominant ASIP $A^A$/- allele showed bay coat color, but not black, suggesting that the ASIP $A^A$ allele represses black coat color development in the hairs of the body, but not in the mane and all four legs. Pedigree analysis showed a consistent relationship between the genotype distribution of the MC1R and ASIP genes and basic coat color patterns, even in the $F_1$ progeny. The results of this study revealed the relationship between the coat color phenotype and genetic background and suggested that useful information may be provided for molecular breeding of Jeju horses.

KIT encodes a mast/stem cell growth factor receptor and is known as a possible candidate gene responsible for dominant white coat color in mammals. To investigate the genetic variation of KIT gene in Korean wild boars(Sus scrofa coreanus), we carried out PCR-RFLP and DNA sequencing for three exons(exons 17, 19, and 20) and intron 19 of the KIT gene in Korean wild boars. PCR-RFLP results using NlaⅢ restriction enzyme in the breakpoint region between exon 17 and intron 17 and AciⅠ restriction enzyme in exon 19 indicate that Korean wild boars did not have previously identified white coat color related splicing mutation and missense mutation, respectively. These results also indicate matings between Korean wild boars could not give white coat color offsprings. We also found new SNPs in exons 19(C2661T) and 20(A2760G). Of these, the SNP in exon 20 is a missense mutation which might induce the change of amino acid iso-leucine to valine. However, no relationship was identified with this missense mutation and coat color. In this study, breed specific new SNPs were identified in exons 19, 20 and intron 19 and these results will give important information for genetic variation of porcine KIT gene.

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.

To understand the relationship between coat color inheritance patterns and genotypes of Extension (E) and Agouti (A) loci in cattle, the genotypes for melanocortin-1 receptor (MC1R) and agouti signaling protein (ASIP) were analyzed in Hanwoo, Jeju black cattle (JBC), and their crossbred progeny. Three MC1R alleles ($E^D$, $E^+$, and e) were found in the black-colored JBC population. JBC had no recessive homozygotes (e/e), but this genotype was predominant in the Hanwoo breed. However, MC1R $E^+$/e Hanwoo did not produce a black coat color as they appeared either as brown or solid red. For ASIP, three genotypes (A/A, A/$A^{Br}$, and $A^{Br}/A^{Br}$) were determined by insertion/deletion of an L1-BT element in Hanwoo. The ASIP $A^{Br}$ allele was rarely observed, and no ASIP $A^{Br}/A^{Br}$ homozygotes were detected in the JBC population. Cattle carrying ASIP $A^{Br}$ did not show any agouti-like brindle pigmentation patterns in either breed or their progeny. The coat colors of the crossbred progeny were discriminated by two colors, yellowish-brown versus dark-brown or black, and their coat colors were directly related to the genotypes of the Extension locus, yellowish-brown (e/e) and dark-brown or black ($E^+$/e), but not to the Agouti locus. ASIP genotypes probably did not affect coat color development in the Hanwoo or crossbred progeny. Our results suggest that the ASIP genotypes do not play key roles in coat color variation, but the MC1R genotypes do direct the phenotypes of Hanwoo, JBC, and their progeny.
