Mucin coat is deposited on the embryos during passage through the oviduct in rabbit. When in vitro cultured blastocysts were transferred to the recipients, the lack of mucin coat might account in part for failure of pregnancy after transfer. The present study were carried out to investigate whether deposition of mucin coat were induced when in vitro cultured blastocysts were transferred to recipients. At 19 ～20 hours post-coitus one-cell embryos were collected by flushing oviducts. These embryos cultured for 72 hours were reached to blastocyst stage. And these blastocysts were transferred to the oviduct of asynchronized (one day later than the donors) and synchronized recipient. To confirm deposition of the mucin coat, blastocysts transferred to the oviduct were recovered at 24 and 48 hours after the transfer. Fifty eight percent of blastocysts recovered from uterus of asynchronous recipient at 24 hours after transfer and 92.9% of blastocysts recovered from uterus of synchronous recipient were 0～10 ㎛ of mucin coat thickness. And 11.8% of blastocysts of asynchronized recipients and 7.1% of blastocysts from asynchronized recipients were in 11～20 ㎛ of mucin coat thickness. When blastocysts were recovered from uterus at 48 hours after transfer, 87.0% of blastocysts from asynchronized recipients and 5.9% of blastocyst from synchronized recipients were in 0～10 ㎛ of mucin coat thickness. And 76.5% of blastocysts of synchronized recipients and 4.4% of blastocysts from asynchronized recipients were in 11～20 ㎛ of mucin coat thickness. From these results it is speculated that the low implantation rate of in vitro cultured rabbit blastocysts transferred to oviduct of recipient was caused by high degeneration of the embryo after transfer and inappropriate deposition of mucin coat.

This article briefly researched the Picture of Welcoming the Governor of Pyongan Province painted by Kim Hong-do, penname Danwon(1745-1818?). The Picture was composed of three parts and its historical and pictorial back-ground were reviewed firstly. And later the dress and its ornament appearing on the Picture were studied. In the historical viewpoint of dress and its ornament, the Picture shown all sorts of dress from lower class maids and servants to higher officials-dignatories and governor, and dealt with nearly all dresses. In order to support and to make better understand the dresses of that age, some Korean literary works of the same period depicting the dress and its ornament were also selected. This article dealt with the dress and its ornament. especially that of 18th century of the Yi Dynasty, and comparatively studied for our folk painting with literary works. Also the picture enabled to make this study was an important data of our old dress and its ornament. This painting was considered as one of our cultural treasures. Several conclusions drawn out from this study as followings: 1) In male and female dress of lower class people; male dress was consist of trouser and coat, and coat, and over the coat SOCHANGYI were used. Female dress was basically consist of skirt and these were white color of their favourite. Mainly simple color was used for clothing and its dress style were CHAKSOO-HYONG (narrow sleeve style) which convenient for a work. 2) Yangban's dress was consist of trouser, coat and over the coat, usually DOPO(over-coat) were used and some case JICKRYONGPO (a sort of over-coat) or CHANGYI were also used. These were GWANGSOO-HYONG (wide sleeve style) of inconvenient for a work. 3) In head-gear, there was no difference of the higher and the lower. They usually used HEUC-KRIP (black Korean hat). The OCKJUNGJA, GONJAKMI (peacock tail), HOSOO (tiger beard), and YOUNGJA (chin strip) were used according to officials ranks as head-gear's oraments. 4) Local petty officials used ordinary dress and CHUPRI (warn-dress) were also used by them, and military officials used war-dress of tight sleeve. 5) The belting of over-coat are different in color according to official grade. The higher grade wore red-wide belt, but generally black narrow belt for ordinary officials. 6) All KISAING girl wore SAMHYEOIJANG upper coat. And their head ornament were black KARIMA for grown KISAING. SAYANG hair for DONGKI or maiden KISAING and BINYEO (an ornamental rod of women's hair) were inserted into the hair of rear down part of head. The water carring maid wore BANHYEOIJANG upper coat and no KARIMA were on head and their coat were gloomy color. Above mentioned are several conclusions, and there migh be a false or erroneous explanations of 18th century dress and its ornament, however I considered they were data for blank period of quite unknown.

The objective of this study was to determine the breed differences in the 3'-untranslated region (UTR) of MC1R mRNA, which may be used to distinguish Korean brindle cattle (Chikso) from other breeds. We investigated the relationship between the variation of 3'-UTR of the MC1R mRNA and coat color among different breeds and the Korean brindle cattle with different coat colors. MC1R mRNA expression levels were determined in accordance with the coat color and hair colors of the tail. Total cellular RNA was extracted from the hair follicles of the tails in Hanwoo, Korean brindle cattle, Holstein and $Hanwoo{\times}Holstein$ crossbred cattle. After cDNA synthesis, PCR was performed. Sequences of the 3'-UTR of MC1R mRNA were analyzed. The 3'-UTR of the MC1R mRNA from different breeds of cattle did not show any variations. There were no variations in the 3'-UTR of the MC1R mRNA in Korean brindle cattle with different coat colors. The levels of MC1R mRNA expression in hair follicles of the tail varied substantially among the Korean brindle cattle with different coat colors, except yellow coat color. Correlation between the MC1R mRNA expression in the hair follicles of the tail and coat color may be present in the Korean brindle cattle, but not between the variations of 3'-UTR of MC1R mRNA and coat color. Further studies to determine the regulation of MC1R mRNA expression from the hair follicles of different coat colors will be beneficial in clarifying the role of MC1R in the coat colors of the Korean brindle cattle.

The purpose of this study is to perform historical reconstruction of the court dress coat in the Daehan Empire in order to make replicas of the artifacts. Following steps were undertaken in the study : literature research of the laws of the era, drawing of the design, embroidering gold work, and tailoring of the coat. Embroidering and tailoring experts were consulted to complete an accurate reconstruction of the dress court. The results of this study are as follows. First, Juimgwan's coat, which was the Court Costume Rule in 1905 was selected as an experimental coat. It was revision of the Court Costume Rule in 1900. The process of selection was based on the amount and easiness of embroidery. Second, the design of the back bodice, chevron, pockets and collar is reflected the pattern of the preceding research, which was analyzed from the laws, the drawing document[Gwanbokjandoan], and artifacts. Third, the gold work embroidery in the back bodice, chevron, pockets and collar was done. The embroidery material were composed of gold threads, such as rough purl, smooth purl, check purl, pearl purl, rococo, and spangle. Couching was used as an embroidery method. The coat was tailored after embroidering. The coat and the buttons were made after analyzing the artifacts. The result of this study can be utilized in the field of historical reconstruction of artifacts in the museum, the designing of stage costume in the performances of reenactment events, drama, and movie of Daehan Empire. Furthermore, this study is anticipated to contribute to the fundamental research of culture contents.

Freshly harvested seed of Chinese milk vetch (Astragalus sinicus L.; CMV) was strongly dormant because of hardseedness. Seeds of freshly harvested germinated only 8% while clipping the seed coat completely overcome the innate dormancy, which indicates inhibition of germination of the seed is mainly due to seed coat (87%). The dormant (intact) hard seeds did not imbibe water whereas the non-dormant (clipped) seeds took up rapidly. In natural environment condition, the hard seed coat dormancy was broken only after 5 months after seed harvest. To break such a strong seed coat dormancy, the chemical and heat treatments were effective. Concentrated sulfuric acid was more effective than dry heat and hot water treatments. Hot water treatment improved germination but the germination percentage was less than 41%. Treatments increased germination due to its effect on the seed coat integrity. A scanning electron microscope reveled that disruption of seed coat layers and subsequent development of numerous crack in the hilum region of the seed and on the seed coat surface of concentrated sulfuric acid treatment and formation of cracks in the dry heat treatments, respectively, were observed in the seed coat surface, which served as water entry points.

A doctor's coat worn by Seo Jae-pil (1864-1951)-National Registered Cultural Heritage No. 607-was conserved with wet cleaning to remove thick wrinkles and brown stains that had been present for a long time. This paper also applied microscopic observation and infrared spectrophotometric analysis to obtain scientific investigation data on the cotton fabric of this doctor's coat. Information about Seo Jae-pil's time as a doctor, the process of changing his English name, and C.D.Williams & Co., which produced the medical coat, revealed that this doctor's coat was worn by Seo Jae-pil between 1892 and 1898 or 1926 and 1939. Additionally, this paper proposes a pad for filling relics that can protect the shape of modern and contemporary clothing, such as Seo Jae-pil's doctor's coat, for display at a museum site. Specifically, this research provides detailed information on the manufacturing of filling pads that can prevent damage to modern and contemporary jackets and coats so that they can be used in the cultural heritage field by developing filling materials for three-dimensional costume artifacts.

본 연구는 한우의 모색발현에 정확히 어떤 유전자가 어떤 유전기작에 의해 관여하고 있는가를 규명하고자 황갈색의 모색을 지닌 한우와 검정모색을 지닌 홀스타인과의 교배를 통해 만든 F2집단의 DNA를 이용하여, MC1R, ASIP 및 TYRP1 유전자형과 한우모색 발현양상을 연관분석 하였으며, 또 한우 집단내에서의 이들 유전자형 빈도를 조사하여 황갈색 한우모색 다양성과 후보유전자 변이의 연관성연구에 필요한 정보를 제공하고자 하였다. MC1R 유전자의 경우 황갈색을 지닌 3두의 유전자형은 모두 e/e 형으로 밝혀졌으며, 검정모색을 지니고 태어난 나머지 3두의 두 좌위에서의 유전자형은 ED/e임을 확인하였는데 황갈색과 검정모색의 비율이 1:1로 나온다는 것은 MC1R 단일유전자가 한우의 모색에 중요한 영향을 미치는 것으로 사료된다. MC1R 이외의 모색발현에 영향을 줄 수 있는 ASIP와 TYRP1 유전자들은 F2 집단에서 염기서열을 분석한 결과 이들 유전자들이 한우 황갈색모색에 주된 영향을 미치지 않는 것으로 나타났다. 하지만 TYRP1 유전자에서 발견된 329번 (Glu329Lys) 아미노산 변이는 TYRP1 단백질의 구조와 화학적 성질에 영향을 줄 수 있는 것으로 사료되어 한우집단에서 황갈색바탕의 모색변이에 영향을 줄 수 있는지에 대한 추가적인 연구가 이루어져야 할 것이다.

Failure mechanisms were investigated for the two layer thermal barrier coatings consisting of NiCrAlY bond coat and $ZrO_2-8wt.\% Y_{2}O_3$ ceramic coating during cyclic oxidation. $Al_{2}O_3$ developed at the ceramic coating/bond coat interface first, followed by the Cr/Ni rich oxides such as $NiCr_{2}O_4 and Ni(Al,Cr)_{2}O_4$ during cyclic oxidation It was observed that the spalling of ceramic coatings took place primarily within the NiCrAlY bond coat oxidation products or at the interface between the bond coat oxidation products and zirconia based ceramic coating or the bond coat. It was also observed that the fracture within these oxidation products occurred with the formation of $Ni(Cr,Al)_{2}O_4$ spinel or Cr/Ni rich oxides. It was therefore concluded that the formation of these oxides was a life-limiting event for the thermal barrier coatings.
