Mourning & funeral ritual means a various kinds of ritual procedures which begins at the time of death, buried and created a graveyard, a manner of wearing funeral garment being mourning the death, finally go back to everyday life. Our mourning & funeral custom was burial at first time. After going through the era of the Three kingdoms, The unified Shilla and Korea dynasty, cremation method has been prevailed. However, based on Chu-tzu celebration in Chosun dynasty, the burial custom has been widely spread again. Nowadays, due to effective land utilization issue, excessive cost for burial and the change of thinking for cremation, the cremation is recognized as remedy of righteous funeral system. At this point, a shroud following existing burial custom burdens considerably for quality, price, size and design of it. Accordingly, it needs anew style of shroud corresponding to cremation system. As an alternative, the shroud is required simplification and standardization ; Firstly, in size, a shroud should be larger than plain clothes and differentiated in small, medium and large. Secondly, the material of a shroud would be white cotton, which can keep from pollution during burning time. Thirdly, it unifies the item. In case of man, 바지(把特, those are trousers), 저고리(赤古里, Korean-style jacket) and Durumagi(周衣, Korean topcoat). In case of woman, 치마(赤　, those are skirt), 저고리(赤古里, Koran-style jacket) and Durumagi(周衣, Korean topcoat).

This study focuses on Korea's traditional-style soryebok, in terms of its foundation, progression, and structural features. The research methods employed here include literature analyses of relevant laws and an official daily gazette, and practical analyses of artifacts and photographic documents. Especially, the artifacts of heukdannyeong(black uniform for officials with a round neck) in the form of chaksu(tight sleeves) were examined, which was regulated as soryebok in Eulmiuijegaehyeok. The term "soryebok" firstly appeared in "使和記略"(Sahwagiryak) written by Park Yeong-hyo, a foreign envoy to Japan, in 1882. Emperor's invitation written in the book asked him to wear daeryebok at the ritual and soryebok to the banquet. Soryebok was not adopted in Gapshinuijegaehyeok in 1884. However, several illustrated documents of the modern banquets at that time reveal that sabok, which was included in the 1884 reform, was used as soryebok. According to the Gapouijegaehyeok in December 1894, courtiers were required to wear heukdannyeong as daeryebok, and add juui(topcoat) and dapho(sleeveless coat) as tongsangyebok when they visited the royal palace. In Joseon's first daeryebok system, the term "tongsangyebok" that had been used in Japan was employed before soryebok was used. According to Eulmiuijegaehyeok in August 1895, the term "soryebok" originated from a costume ritual for courtiers of the Joseon Dynasty. Soryebok featured heokbannyeong chaksupo, samo (winged hat for officials), sokdae(belt), and hwaja (shoes for officials). There are around 24 artifact pieces of heukdannyeong in the form of chaksu(tight sleeves) in the following locations: garments of Prince Heungwangun and Wansungun, the court artifacts, Korea University Museum, Yun Ung-ryeol's family housed at Yonsei University, and Kyungwoon Museum. Artifacts have mu(godet) pulled back and a topcoat-like triangular mu. In conclusion, heukdannyeong, traditional-style soryebok has significance in the history of modern dress because streamlined traditional clothes and newly introduced Western dress system were able to be combined.

Today's requirements for print-press runnability and print quality demand an optimised absorption and adhesion of printing ink on the paper surface. Modern coating concepts for high glossing offset grades use ultra fine pigments, whereas binder level has continuously been decreased to a minimum in recent years to achieve the highest possible sheet gloss development and for economical reasons. Both the ultra fine pigments and the reduced binder levels lead in many cases to a faster ink setting rate. On the other hand, matt paper grades use relatively coarse pigments leading to a slow ink setting compared to the high glossing papers. Both too fast and too slow ink setting properties implicate drawbacks in print quality and print press runnability. The mechanisms behind the interactions between ink and coating have been presented in many previous publications. The purpose of this study was to determine and quantify how the ink setting rate is influenced by pigment system (GCC and GCC/clay blends), latex level and latex properties in the topcoat of double coated sheet fed offset paper. The roles of binder level and type in the precoat were also assessed. The effect of calendering (temperature and pressure) was studied with one formulation. The resulting ink setting characteristics were tested using three different laboratory testing instruments. The correlation amongst the different laboratory testing methods is discussed. The results show that by varying the latex properties, the pigment system and/or latex addition level, the ink tack development of ink applied to a topcoat pigment system can be significantly influenced. It can be slowed down as often desired with ultra fine pigments or speeded up in the case of coarse pigments. There was no visible effect on the ink setting rate by using different binder systems in the precoat..

Medium carbon steel was aluminized by hot dipping into molten Al or Al-1%Si baths. After hot-dipping in these baths, a thin Al-rich topcoat and a thick alloy layer rich in $Al_5Fe_2$ formed on the surface. A small a mount of FeAl and $Al_3Fe$ was incorporated in the alloy layer. Silicon from the Al-1%Si bath was uniformly distributed throughout the entire coating. The hot dipping increased the microhardness of the steel by about 8 times. Heating at $700-1000^{\circ}C$ however decreased the microhardness through interdiffusion between the coating and the substrate. The oxidation at $700-1000^{\circ}C$ in air formed a thin protective ${\alpha}-Al_2O_3$ layer, which provided good oxidation resistance. Silicon was oxidized to amorphous silica, exhibiting a glassy oxide surface.

The effect of hot-dip aluminizing on the corrosion of the low carbon steel was studied at $650-850^{\circ}C$ for 20-50 h in $N_2/0.5%\;H_2S$ gas. The aluminized steel consisted primarily of the Al topcoat and the underlying Al-Fe alloy layer. Aluminizing drastically improved the corrosion resistance by forming the ${\alpha}-Al_2O_3$ surface scale. Without aluminizing, the steel formed nonadherent, fragile, thick scales, which consisted of FeS as the major phase and iron oxides such as FeO, $Fe_3O_4$ and $Fe_2O_3$ as minor ones.

The effect of coating thickness on the contact fatigue and wear of thermal barrier coatings (TBCs) are investigated in this study. The same bondcoat material thickness (250 ㎛) are used for each sample, which allows the effect of the coating thickness of the topcoat to be investigated. TBCs with different coating thicknesses (200, 400, and 600 ㎛) are prepared by changing processing parameters such as the feeding rate of the feedstock, spraying speed, and spraying distance during APS(air plasma spray) coating. The damage size on the surface are strongly affected by the coating thickness effect. Although the damage size from contact fatigue using a spherical indenter diminish at a TBC of 200 ㎛, a high wear resistance such as a low friction coefficient and little mass change are found at a TBC of 600 ㎛. These results indicate that the coating thickness strongly affects the mechanical behavior in TBCs during gas turbine operation.

경사화 두께를 갖는 열차폐 코팅의 열적 내구성과 열적 안정성에 대한 코팅층 두께의 영향을 화염 열피로 시험과 열충격 시험을 통해서 조사하였다. Bond 층과 top 층은 각각 Ni-Cr계 상용 MCrAlY 분말과 상용 이트리아 안정화 지르코니아 (YSZ) 분말을 사용하여 니켈기지의 초내열합금 모재 (GTD-111)에 대기 플라즈마 용사법 (APS)으로 코팅층을 형성하였다. 1100 ℃의 화염으로 1429회 열피로 시험 후 bond 층이 일부 산화되고 top 층과 bond 층 계면에서 열화에 의한 산화층 (TGO)이 관찰되었으나, 코팅층 부위와 관계없이 균열이나 박리현상 없는 양호한 미세구조를 나타내었다. 1100 ℃ 열충격 시험결과, 37회 열충격 테스트 후 코팅층의 얇은 부위에서 박리가 시작되어 98회 시험 후 코팅층의 50% 이상이 박리되었으며, 코팅층의 두께가 얇게 형성된 부위는 코팅층이 두껍게 형성된 부위에 비해, top 층의 박리와 함께 bond 층의 산화가 많이 진행되었으며, 코팅층 두께가 상대적으로 두껍게 형성된 부위에서 열차폐 효과의 증가로 인해 bond 층의 내산화성과 열적 안정성이 우수한 것으로 나타났다.

The relationship between acoustic property and coating hardness of musical instruments was investigated using a sound level meter and a pendulum hardness tester. Urethane topcoat, oil stain, natural oil varnish, and UV-curable epoxy acrylate coatings were applied on four different substrates: Paulownia coreana, Pinus koraiensis, Castanea crenata var. dulcis and Pinus densiflora. The influence of the coating type on the acoustic properties was stronger than that of the substrate. In the case of an oil stain formed with tacky coating layer, the sound pressure level (SPL) and surface hardness decreased with increasing of coating thickness. In the other coatings, SPL decreased and hardness increased as the coating layer thickened. However, SPL began to increase again at coating thickness above $100{\mu}m$.

This study analyzes excavated Danryeong of the same period to understand differences between female and male Danryeong, and to identify characteristics of female Danryeong, including their purpose, then-name and women's wearing of them. The subject female Danryeong were estimated to be worn in the late 15th century and the early 17th century, and newly-discovered female Danryeong, along with those examined in the Song Mi-kyeong's study, were studied. This study found that female Danryeong have distinctive characteristics from male's in many aspects such as ease of a garment, sleeve design, Hansam (a layered sleeve to cover hands), shape of Moos (side pleats), Goreum (a coat string), Dae (a belt). From this finding, the purpose of female Danryeong can be assumed: a ceremonial robe, which is different from that of mem's official robe. Female Danryeong began to disappear as Wonsam, a ceremonial topcoat, emerged. From the transitional Danryeong and excavated Wonsam, female Danryeong were estimated to be used as ceremonial robes in the mid Joseon period when Wonsam had yet to be created; and they were estimated to be called "Dansam" or "Wonsam."
