The purpose of this study is to examine how to sew the hem of men's coat which were excavated from the Yeosan Song Clan's tombs that are thought to be formed between the late 15th and the late 16th centuries, findings of the study can be summarized as follows. 1. Andan, or inside facing was used to prevent the hem from being worn or swollen or to make the hem properly arranged. It was generally used for single-layered and cotton-quilted coat for men. Deotdan was used mainly for men's coat having oblique cutting lines and jemuldan for those having straight cutting lines. In single-layed coat for men, the width of andan was widened a little as the times moved from the late 15th to the late 16th century, but in cotton-quilted ones, the width was not significantly changed. 2. Fixing the lining and the upper was used as a method to prevent the lining of men's coat from being pushed out or the hem of the clothes from being swollen. The method was generally used for double-layered, cotton and cotton-quilted coat for men. The double back-stitching was usually used for double-layered and cotton coat for men and the broad-stitching for Cotton-quilted ones. 3. Among men's coat, those whose siding was partially opened were less spare in the lower end than those whose siding was wholly opened. For this reason, the former clothes were more likely to have the tip of the siding easily torn. To solve this problem, overhand knotting 1, overhand knotting 2 and lotus-flower knotting strings were used for men's coat whose siding was partially opened. Among the three types, lotus-flower knotting was most elaborate in form. For men's coat, overhand knotting became gradually replaced by lotus-flower knotting as the times moved from the late 15th to the late 16th century.

This study was executed to investigate scanning electron microscopic characteristics of Korean Rhus lacquer coats. With the unrefined coat, distilled water, sodium hydroxide, acetic acid, ethyl alcohol, cold-check test, and accelerated weathering were performed after refining treatment. These treated lacquer coats were discussed through observation by scanning electron microscope and the obtained results were summarized as follows: 1. Compared with unrefined coat, the refined coat of Korean Rhus lacquer showed more even surface with regular distribution of dispression. 2. Korean Rhus lacquer coat heated at $120^{\circ}C$ for 3 hours revealed no observable difference irrespective of refining and unrefining. 3. Korean Rhus lacquer coat treated by distilled water, sodium hydroxide, acetic acid. ethyl alcohol, cold-check test. and ultraviolet radiation showed significant characteristics compared with untreated coat. Especially. large deformation and checkings were observed by cold-check test and ultraviolet radiation respectively. 4. The Korean Rhus lacquer coat radiated by ultraviolet ray showed 0.11 duller and 1.41 brighter than non-radiated coat through color difference calculator.

Effects of top coat morphology and thickness on thermal fatigue behavior of thermal barrier coatings (TBC) were investigated in this study. Thermal fatigue tests were conducted on three coating specimens with different top coat morphology and thickness, and then the test data were compared via microstructures, cycles to failure, and fracture surfaces. In the air plasma spray specimens (APS1, APS2), top coat were 200 and $300{\mu}m$ respectively. The thickness of top coat was about $700{\mu}m$ in the perpendicular cracked specimen (PCS). Under thermal fatigue condition at $1,100^{\circ}C$, the cycles to top coat failure of APS1, APS2, and PCS were 350, 560 and 480 cycles, respectively. The cracks were initiated at the interface of top coat and thermally grown oxide (TGO) and propagated into TGO or top coat as the number of thermal fatigue cycles increased. For the PCS specimen, additive cracks were initiated and propagated at the starting points of perpendicular cracks in the top coat. Also, the thickness of TGO and the decrease of aluminium concentration in bond coat do not affect the cycles to failure.

The aim of the present study was to identify coat color associated genes that are differentially expressed in mature Korean brindle cattle (KBC) with different coat colors and in Hanwoo cows. KBC calves, before and after coat color appearance, were included. Total cellular RNA was isolated from the tail hair cells and used for microarray. The number of expressed coat color associated genes/probes was 5813 in mature KBC and Hanwoo cows. Among the expressed coat color associated genes/probes, 167 genes were the coat color associated genes listed in the Gene card database and 125 genes were the pigment and melanocyte genes listed in the Gene ontology_bovine database. There were 23 genes/probes commonly listed in both databases and their expressions were further studied. Out of the 23 genes/probes, MLPH, PMEL, TYR and TYRP1 genes were expressed at least two fold higher (p<0.01) levels in KBC with brindle color than either Hanwoo or KBC with brown color. TYRP1 expression was 22.96 or 19.89 fold higher (p<0.01) in KBC with brindle color than either Hanwoo or KBC with brown color, respectively, which was the biggest fold difference. The hierarchical clustering analysis indicated that MLPH, PMEL, TYR and TYRP1 were the highly expressed genes in mature cattle. There were only a few genes differentially expressed after coat color appearance in KBC calves. Studies on the regulation and mechanism of gene expression of highly expressed genes would be next steps to better understand coat color determination and to improve brindle coat color appearance in KBC.

택 코트 사용조건에 따른 재활용 아스팔트 혼합물의 부착전단 강도를 평가하였다 시공온도에 따른 부착전단강도를 평가하여 보면 신재와 구재에 상관없이 시공온도 $30^{\circ}C$에서의 값이 $10^{\circ}C$에 비하여 약 10~20%증가함을 알 수 있었다. 또한 재생아스팔트 혼합물의 경우 택 코트를 사용하지 않았을 때 부착전단강도가 특히 낮아서 현장에서 종종 발생하는 접착면 종방향 균열의 직접적인 원인이 될 수 있음을 나타내었다. 택 코트의 양생시간에 대한 부착전단강도의 영향은 시공온도의 영향보다 대체로 적었다.

In the present communication literatures pertaining to the coat color of Jindo dogs, the natural monument of Korea, have been reviewed. It was reported that there were seven different coat colors in Jindo dogs. They are yellow, white, red, black, tiger-like, grey, and spotted. The yellow and red dogs have typical color markings called "Yibaik", and black dogs have yellow or white color markings called "Nenoonbagi". All Jindo dogs, which have 7 different coat colors with typical color markings, could be found nowadays. The pictures of those Jindo dogs were taken and presented in this communication. It was felt that the coat colors of Jindo dogs should not be limited to yellow and white. And Jindo dogs should be judged not by their coat color but by their noble characteristics.

Bovine coat color is decided by the melanocortin receptor 1 (MC1R) genotype mutation and melanogenesis. Specially, in the various cattle breeds, dominant black coat color is expressed by dominant genotype of $E^D$, red or brown is expressed in the frame shift mutation of recessive homozygous e by base pair deletion and wild type of $E^+$ is expressed in various coat colors. However, not very well known about the effected of MC1R genotype mutation on the coat color through family lines in KBC. Therefore, this study were to investigate effect of MC1R genotype mutation on the coat color, and to suggest mating breed system in accordance with of MC1R genotype for increased on brindle coat color appearance. Parents (sire 2 heads and dam 3 heads) and offspring (total : 54 heads) from crossbreeding in KBC family line with the MC1R genotype and phenotype records were selected as experimental animals. The relationship between melanocortin 1 receptor (MC1R) genotypes expression verified by PCR-RFLP, and brindle coat color appearance to the family line of the cross mating breed from MC1R genotype pattern was determined. As a result, 4MC1R genetic variations, $E^+/E^+$ (sire 1), $E^+/e$ (sire 2 and dam 3), $E^+/e$ with 4 bands of 174, 207 and 328 bp (dam 1) and $E^+/e$ with 3 bands of 174, 207, 328 and 535 bp (dam 2) from parents (sire and dam) of KBC. However, 3 genetic variations, e/e (24%), $E^+/E^+$ (22%) and $E^+/e$ (56%) were identified in offspring. Also, brindle coat color expressrated was the e/e with the 0%, $E^+/E^+$ with 67% and $E^+/e$ with 77% from MC1R genotype in offspring on the cross mating of KBC. Furthermore, when the sire had $E^+/e$ genotype and the dam had $E^+/E^+$ with the 3 bands or $E^+/e$ genotype, and both had whole body-brindle coat color, 62% of the offspring had whole body-brindle coat color. Therefore, the seresults, the mating system from MC1R genotype patterns of the sires ($E^+/e$) and dams ($E^+/E^+$ with the 3 bands or $E^+/e$) with brindle coat color may have the highest whole body-brindle coat color expression in their offspring.

The purpose of this study is to suggest new designs and patterns for men's coat by deconstructing and restructuring 18th and 19th century men's coat. In the postmodern society, the reinterpretation of the past fashion trends or items through extensive historical investigation has been frequently used as new design motifs and the new source of creative fashion design. Especially in the contemporary society, as multifarious forms and presentations are emphasized even in the men's fashion, it is urgently required more than ever to do thorough and extensive research for the design and structure of men's fashion. Therefore, through historical research on men's fashion, the 18th and 19th century men's coat, which is generally considered to be the most developed one in the concept and shape of 'coat,' has been reinterpreted and deconstructed to make new design for men's coat which corresponds to the trends and sensibility of contemporary fashion. In addition to this, to facilitate practical use of this new design by fashion public, the plane patterns for the actual production of these coat designs were presented.

In traditional Korean medicine, inspection of the tongue is an important method of making medical diagnoses and determining prognosis. We surveyed the fluorescence characteristics of the tongue coat in the ultraviolet light. The tongue coat comprises micro-organisms, blood metabolites, leukocytes from periodontal pockets, large amounts of desquamated epithelial cells released from the oral mucosa and different nutrients. In the ultraviolet light tissues of the oral cavity generally emit weak red or green fluorescence, which is not easily seen by the human eye, but is readily detected. This fluorescence has been proved to be due to the production of porphyrins by oral micro-organisms. While the composition of motile micro-organisms on the dorsum of the tongue is not constant, variations also occur persistingly in the fluorescence characteristics of the tongue coat. But because live bacteria contain a variety of intracellular biomolecules that have specific excitation and emission wavelength spectra characterizing their intrinsic fluorescence, the tongue coat emits fluorescence. the tongue itself, on the other hand, emits very weak or not fluorescence. In conclusion, we suggests that the uncoated tongue area be eliminated from the coated tongue area with the difference between the fluorescence characteristics of the tongue and that of the tongue coat.
