Though Adolf Loos, an architect of 1920s said 'ornament is sin', feature of decoration has big gravity in modern architecture & its design trend. Embellishment as a new genre that combined new cultures, trends, and technologies is finally ascribing to skin design approach. For instance it is preference to rags, coarse fabric, external shape of fragments. Expressing surface as a ceremony in architecture or indoor design is also belong to the same category. In this respect, as a new approach on skin, the study focuses on visual and spatial changes that stimulate user's sensibilities consequently since skin design is based on human senses and sensibilities. As skin design expands the scope of human experiences comprehensively, and classify boundaries between internal parts and external parts or make them ambiguous, aesthetic embodiment on new trends is getting done. Through skins on buildings, a message is transmitted to a whole city, an opportunity for the city to be expanded into a new space is created, and human senses are stimulated through refusing a traditional sides by rediscovering decorations in space design and adapting the sides made in limitlessly-expressed styles. Thus, as a new approach on the skins that transmit a message through human senses, the study is to contemplate skin design, and to interpret them as works to eliminate boundaries among architecture, fashion, interior/exterior space design(especially exhibition and international fair)following their suits. Through interpreting this subject, the study is to understand and analyze comtemporary expansion situation on interactions among fashion and architecture, and interior design.

This study conducted non-destructive analyses of the material features of seven gilt-bronze crowns of Baekje Kingdom that were excavated in the Cheonan, Gongju, Seosan, Iksan, Naju, and Hapcheon areas. A typical Baekje gilt-bronze crown has a conical inner crown and an outer crown embellished with vertical ornaments on the front and the back, a tube topped with a hemispherical ornament, and other ornamentation. Diverse designs (e.g., dragon, bonghwang, flowers, and plants) were applied using a range of techniques, including repoussé, chasing, openwork, and engraving. Formal features differ among the crowns according to their period of production and site of excavation. The substrate metal of the crowns is either pure copper or mixed copper with a small amount of lead. The crowns were amalgam-plated on the surface with pure gold or gold with a small amount of silver. The crown from Okjeon Tomb No. 23 in Hapcheon in the ancient Gaya region has a high silver content, which appears to be a regional feature. In addition, this crown from Okjeon Tomb No. 23, which can be categorized as Baekje-style gilt-bronze crown, seems to be plated at most three times, while the gilt-bronze crowns found within Baekje Kingdom territory were plated once or twice.

Stainless steel is being used widely for various purposes due to its good corrosion resistance. There has been much research to produce a colored and corrosion-resistant stainless steel by several methods to use in decorating. In this experiment, we coated TiN(C,O,H)films on the SUS304 substrates with the DC magnetron sputtering system and then studied the texture and color of the films as a function of additional gases being inserted into the system. A (220) texture of TixN film changed to (200) by the addition of either hydrogen or the acetylene and changed further to (111) with an increase of the additional acetylene content. The addition of oxygen gas changed from the texture(220) to (111) to (200). The color of the TixN film changed from gold to gray to green with the increase of the content by the addition of oxygen gas, while it changed to pink and finally to gray with the increased of the content by the addition of acetylene gas. Reflectance increased in the region of short wavelength by the addition of hydrogen, but decreased with the increase of the oxygen and the acetylene content.

In this study, the H₂S gas sensing characteristics were evaluated using surface-modified SnO₂ microparticles by tip sonication. The surface-modified SnO₂ microparticles were synthesized using the following sequential process. First, bare SnO₂ microparticles were synthesized via a hydrothermal method. Then, the surfaces of bare SnO₂ microparticles were modified with Ti nanoparticles during tip sonication. The sensing characteristics of SnO₂ microparticles modified with Ti were systematically investigated in the range of 100-300℃, compared with the bare SnO₂ microparticles. In this study, we discuss in detail the improved H₂S sensing characteristics of SnO₂ microparticles via Ti nanoparticle modification.

A stone seated bodhisattva (Sinsu5971) was discovered in Pyeongchang-gun, Gangwon-do in 1974 and was transferred to the Chuncheon National Museum upon its opening in 2002. The statue had damage to wide areas and was thus difficult to restore. This study utilized 3D scanning and 3D printing technologies to identify the overall form of the statue and the degree of damage, which allowed the restoration of lost portions that otherwise could not have been accurately restored to their original shape. Prior to the conservation treatment, the pigments used to decorate the surface were investigated using an optical microscope, and their main components were analyzed with a p-XRF (Potable X-ray Fluorescence Analyzer). The deteriorated lacquered surface was stabilized using animal glue and consolidated with stone strengthener (OH-100). The investigation found that the surface of the statue was made of zeolite that was lacquered and then gilded. As for pigments, white lead was used for the white color and red lead and cinnabar were used for red. The lost portions were redesigned by mirroring the remaining parts with 3D technologies. However, it was difficult to affix the 3D printing outputs to the statue without visible gaps since the damaged parts suffered flection. The portions of the outputs to be connected to the statue were thus modified and supplemented. It was also difficult to collect data on the properties of 3D printing materials due to the lack of previous in-depth study. These obstacles are subjects for further study.

This study is re-creational experiment of Goryeo gold-painted decoration based on the research of the gold remaining and gold painting technique on the two pieces of Goryeo gold-painted celadon and the three pieces of Chinese gold-painted porcelain on North Song period which ones have been owned by National Museum of Korea since 2007. For the observation of glue state and color developing ability, four kinds of agglutinative agent and gold powder were mixed over the porcelain sherds, then gradually fired from $100^{\circ}C$ to $1200^{\circ}C$. Visual effect and ideal temperature were measured. Among of them, oil and glue showed the best results in glue state and color developing ability. Through those results, the entire Goryeo engraved celadon were reproduced in modern facilities. Oil and glue were gold-painted over the glaze then it was fired at the ideal temperature 700 to $800^{\circ}C$. For observation the binding condition, the gold-painting cross section was looked by the scanning electron microscope (SEM). As the result, oil and glue did not make much difference in Agglutinative agent, but gold was good, the color developing ability, however, in the case of oil, the edge of gold is curled because of its interfacial tension, and it is not dried well at room temperature so the working property is not as good as the glue. Glue more effective in terms of work efficiency, but color developing ability to fall slightly in this experiment were able to see through.

Pattern refers to singular or repetitive decorative form in a blank surface, Also pattern is not just something to simply fill in the blanks, and has more meanings. Pattern reflects the specific culture or regional feature. So Depending on which pattern to use, creator can give particular of identity. which is generally utilized in visual arts such as painting, architecture, craft, as well as animation. Pattern in animation plays a role of decorating background or surfaces of characters' outfits or props. And Parttern is effective way to describe the story of the times and space environment of the background. Tomm Moore, an animation director in in Ireland mainly produces animations based on traditional folk stories or myths. He usually utilizes cultural and artistic factors related to the themes in his work production. One example is the insertion of pattern closely associated with the narratives and backgrounds of animations to create profound scenes. Tomm Moore used the Irish Celt pattern in Secret of Kells (2009) and Song of Sea (2014) and Islam geometric pattern and plant pattern in a short nimation named On Love from Kahlil Gibran's The Prophe (2014). This study attempts to examine the historical and cultural foundation and the narratives of these two animations, Song of Sea(2014) and Kahlil Gibran's The Prophet: On Love (2014) in which Tomm Moore participated as the director and producer, exploring their relevant traditional patterns. Moreover, it also attempts to analyze how these traditional patterns are utilized in the animations.

In this paper, Gilt-bronze Standing Avaolkiteshvara (National Treasure No. 293, M355) excavated at Gyuam-ri in Buyeo was observed with a microscope to identify the production technique applied to it. It was also analyzed with XRF and hard X-ray to identify the composition and the surface treatment techniques and casting method applied. In this statue, Avalokiteshvara is standing upright on a lotus pedestal. The lotus designs on the pedestal and those on the shawl flowing down on both sides of the statue are characteristic of Buddhist statues from the seventh century or later. The use of supports to affix the outer and inner molds and traces of injected cast were observed in the interior of the pedestal. The blisters on the arms and pedestal created during the bronze casting indicate the use of lost-wax casting, which was popularly employed for the production of mid- or small-sized gilt-bronze Buddhist statues in ancient times. The composition analysis identified a copper-tin-lead ternary alloy in the interior of the statue that was conventional used in the sixth and seventh centuries. It is likely that this simple alloy was used to facilitate casting and produce clearer expressions of designs and ornaments on the statue. Mercury (Hg) was detected on the surface of the statue, indicating the use of amalgam-plating with gold (Au) dissolved in mercury. This plating method is a common surface treatment technique used for small gilt-bronze statutes in ancient Korea.

화석연료의 남용으로 지구 온난화가 심화되어 환경과 생태계변화가 가속화되고 있고, 급속한 산업의 발달과 인류 삶의 질 향상에 따른 에너지 수요가 급증하고 있는 실정에 있으며, 일본 후쿠시마 원전사태로 원자력 에너지의 위험성으로 지구 인류환경은 심각한 국면을 맞이 하고 있어 대체 에너지의 하나로 핵융합 에너지 필요성이 증대되고 있다. 핵융합 에너지 연구 개발은 우리나라에서 KSTAR가 1997년부터 건설하기 시작하여 지난 2007년에 완공되어 지금 운용 중에 있고, 국제적으로 미국, EU, 러시아, 중국, 한국, 일본 인도가 참여하는 ITER 국제 공동프로젝트가 2004년에 건설을 시작하여 프랑스 카다라쉬에 실증 플란트를 건설 중에 있다. 이러한 핵융합 반응을 위해서는 10e-7이상의 높은 진공과 1억$^{\circ}C$ 이상에서 중수소와 삼중수소가 반응하여 발생하는 플라즈마를 제어 할 필요가 있으며, 초고온의 핵융합 플라즈마를 가두고 가동시키기 위해서는 약 12Tesla이상의 고자장 마그넷이 필요하다. 현재 ITER 실증 플란트에 사용되는 고자장 마그넷은 TF (Toroidal Field)코일과 CS (Central Field)코일에 Nb3Sn 초전도선재가 핵심부품으로 사용되고 있으며 ITER프로젝트에서는 약 850톤의 Nb3Sn 초전도선재가 사용될 전망이다. 그 중에서 일본 25%, EU, 러시아와 한국이 각각 20%, 중국7%, 미국8% 할당되어 참여국 대부분은 초전도선재를 전략적으로 공급하고 있다. 초전도 선재의 크롬도금은 1~2 마이크로미터 이하의 균일하고 얇은 도금 두께와 밀착성이 우수한 품질이 요구된다. 일반적으로 크롬도금은 산업현장에서 컨베이어 벨트 방식으로 장식이나, 내식성 및 내마모성의 특성을 필요로 할 때 사용되고 있으나, 선재에 크롬도금을 릴투릴(Reel to Reel) 방식으로 적용되는 경우는 세계적으로 아주 드물다. 핵융합 마그넷의 CICC(Conduct In Cable Conduit)도체를 만들기 위해서는 초전도선재를 이용, 3(Sc 2+OFC 1)$^*3^*5^*5^*6$형태로 연선과 케이블링을 하게 되며, 초전도 선재를 연선하고 케이블링을 할 때 크롬 도금층이 박리될 가능성이 있어 크롬도금 방법과 프로세스를 특별히 고안할 필요가 있다. ITER핵융합로 마그넷의 TF코일은 높이 14m, 폭 9m 최대자장 12Tesla, 최대전류 68kA, CICC도체 직경이 40mm로서 그 초전도 조관/도체 내부에 0.82mm 직경의 Nb3Sn 초전도 선재가 약 1350가닥으로 연선과 케이블링으로 구성되어 있다. ITER 핵융합 마그넷용 초전도 선재의 크롬도금은 마그넷 권선 후 Nb3Sn 초전도물질을 형성하기 위해서 $650^{\circ}C$에서 500시간 열처리를 실시하며 열처리 시 초전도 선재의 소선들 사이에 발생할 수 있는 소착을 방지하고, 초전도 선재에서 발생하는 AC loss를 감소시키며, Quench시 발생되는 열을 쉽게 확산시킴으로써, 초전도 마그넷의 열적 안정성(Thermal Stability) 향상과 필요에 따라서 소선간 통전울 가능하게 한다. 고려제강의 자회사인 케이에이티는 크롬도금 밀착성이 우수하고 도금두께 0.1마이크로 미터 이내 제어가 가능한 얇고 균일한 도금품질을 개발하여 한국형 핵융합 실험로인 KSTAR에 65톤 전량 공급하였고, 크롬 도금된 무산소동 선재 32톤과 초전도 선재 93톤을 전량 ITER 프로젝트에 공급하고 있으며, 2013년도 상반기에는 공급을 마무리할 예정이다.

The Octagonal nine storied pagoda of Woljeongsa Temple consists mainly of granite with the rockforming minerals quartz, plagioclase, microcline, and biotite. The surface of the stone stupa is light brown that has been discolored by the rust from the metal ornament and aids. The surface of the stylobate and roof stone is colonized by biological contaminants. Therefore, a comprehensive deterioration diagnosis was carried out in this study, and conservation treatment was conducted. It was proven that the $Fe^{2+}$ yield increases depending on the count of poultice used with oxalic acid, but the $Mg^{2+}$, $Al^{3+}$, and $Ca^{2+}$ yields were marginal following the preliminary test. Therefore, the use of poultice is an effective way of removing the rust, and only marginally influences the rock. The biological contaminants were removed through dry cleaning, and the soil located under the contaminants was removed through wet cleaning. Based on this, the dry and wet cleaning of all the biological contaminants, and the use of poultice with oxalic acid, were done to remove the rust. For the conservation treatment of the metal ornament, the rust was removed through physical cleaning, and anticorrosion treatment was performed on the iron ornament using Renaissance wax and copper ornament by BTA.
