Conservation re-treatment of dagger and scabbard in Gyeongju National Museum, which were excavated from Gyerim-ro Tomb No. 14 (Treasure No. 635) was carried out after a wide-scale dissembling in order for publishing a report and holding a special exhibition. The interior shape of the iron dagger which was disclosed by ornament plates was confirmed by X-ray investigation. The results of XRF analysis which was used to analyse compositions of the golden ornament plates reveal that having more than 3% of copper distinguishes it from other Silla gold artifacts. The conservation treatment progressed in a way that surface contaminants were removed and insecure areas were consolidated. The original shape of the iron dagger and scabbard was found after adhering and restoration. With the ornament plates staying on the iron dagger, a stand in acrylic for display and storage was made, which is able to place the dagger and scabbard in the safest way.

This study examined each handiwork method of 4 filigree artifacts from Neungsan-ri temple site in Buyeo, Korea through material characteristic and microstructure analysis. As a result, it was indicated that all of the artifacts have comparatively higher purity than 22.7K and some of filigree artifacts showed that gold is alloyed with silver at a certain ratio. Gold thread that decorates surface showed thickness of 0.2~0.8mm and displayed various forms of section. Gold granule indicated that 2 or 3 granules are adhered together and they are 0.3~0.8mm in diameter. Trace of soldering was observed from gold thread and gold granule joints on surface and it confirmed a possibility of being soldering using gold solder through componential analysis. Also, it reveals a surface decorated with pigments such as cinnabar(HgS) and black.

This study is to examine the manufacturing technique based on scientific investigation and analysis on Steel-Plated Jewel Beetle's Adornment gilt-bronze openwork remains excavated from No. 100 site at Hwango-dong Gyeongju. As a result of the investigation on the manufacturing revealed that riveting was adopted to connect gilt-bronze openwork plates and steel plates, followed by mercury amalgam plating method and carving of the patterns by means of the dotted line engraving technique. There were some traces on the surface of Jewel Beetle wings that show the use of pins for fixing, which seems to be the result of recycling or processing. The sectional analysis shows the high possibilities that varnishing with lacquer was adopted for wing adhesion, and it was confirmed that varnishing with lacquer was used on the strap pendant plate to prevent corrosion.

Amethyst gems represents thermal effects of far-infrared emission, promotes the body's metabolism, and attracts attention as an eco-friendly interior material. In this paper, amethyst increase the value of jeweling by applying the characteristic purple motif, furthermore, I will intend to develop of design model. Metal crafting of brooch & necklace in the works performed based on the organic three-dimensional shape of the Rhino CAD Data. It was made possible through the precise laminated wax processing and then combining the amethyst. I researched the ornament modeling by applying the 'Golden Ratio', and suggesting utilizing method for interior jewel modeling, and also, is expected that this paper on the amethyst modeling design can contribute to the manufacturers' productivity.

The term jinjuseon(眞珠扇), meaning literally a pearl fan, refers to a fan decorated with precious stones for use in royal wedding ceremonies. This study examined a jinjuseon housed in the National Palace Museum of Korea (NPMK) which currently lacks jeweled ornaments. In order to determine whether pearls or other gemstone settings originally ornamented the fan,the surface and composition of the gray materials remaining on the washers were investigated and the fan was compared with other artifacts decorated using similar techniques. The analysis revealed that the gray materials visible around the round rims of the washers contain tin-lead alloys. The traces of folded nails suggest that soldering was not applied. The remains of the infill observed in other artifacts with bezel settings indicate that this jinjuseon in the NPMK collection was produced using abezel setting technique wherein pearls or other gemstones were affixed by filling cylindrical bezels with tin-lead alloys.

The main purpose of this paper is to introduce 'Inframince' in modern and contemporary architecture. The Inframince(English: infra-thin) is a concept coined by Marcel Duchamp. The conceptual definition of the term "Inframince" by Marcel Duchamp replied that the notion is impossible to define, "one can only give examples of it:". It describes fine indirect perceptions of physical phenomena. Inframince is conductor of two dimensions into three, the essential dynamic in the practice of making space. Inframince is the interval between an inhabitant and their environment that both connects and separates. This study deals with the difficult situation how Contemporary Architecture represents itself over the 20th century modernity and asks the question how it presents its ornamentality. In order to analyse contradictory situation between self-referentiality and ornamentality in Modern/Contemporary Architecture we need to survey the historical process of changing position of ornaments and its meaning in time. The article also analyze the selected works of contemporary architects like Herzog & de Meuron, Jean Nouvel, to show that the trend reversal continues now more than ever. The Architectural surface must be a different kind of media that can communicate in different way with compared to conventional ornament. If we understand Duchmp's Inframince to be the provocation of the unuseful things, and if we interpret Contemporary fact that all specific Architectural Surfaces have been dissolved in timelines, it shows us post-trend of the Surfaces via conspicuous consumption or desire.

공정용 플라즈마는 반도체 웨이퍼 가공, 평판형 디스플레이, 자동차 및 산업용 부품 코팅, 장식용 코팅에 널리 사용되고 있다. 이를 위한 장비 개발은 플라즈마에 대한 깊은 이해가 없이는 불가능하여 주로 선진 장비 회사의 모델을 참고하여 유사하게 만드는 수준에서 진행되어 왔는데 2D, 3D modeling이 가능한 전산 유체 모델은 일부 상용화 패키지 S/W까지 등장하였으나 플라즈마와 수치 해석에 대한 기본적인 지식이 없이는 사용이 매우 어렵다는 단점이 있어 국내의 일부소자회사의 장비 관련 연구팀 정도에서만 사용이 가능했다. 이를 중견 장비 업체들에 까지 확대하기 위한 작업의 일환으로 2D-ICP, 2D-CCP model의 기본적인 기능을 갖추고 기하적 크기는 파라미터 방식으로 사용자가 조절할 수 있도록 만든 framework을 개발하려는 시도에 대해서 논의 하고자 한다.

금(Au) 및 금의 합금도금은 주로 극히 얇고 색상만 나타내는 정도의 장식용으로 많이 사용되고 있으나 단순한 장식품뿐만 아니고 스마트폰, 정보통신 서버, 전자기기, 자동차, 전지용에도 널리 사용되고 있다. 특히 로켓공업이나 인공위성의 와곽부, 엔진에는 필수적이다. 현재 미국의 금도금액 85%는 전자부품과 인공위성(NASA) 등의 공업용에 사용되고 있다. 금도금의 이용가치는 주로 내식성이며 전기저항이 작고 열전도성이 뛰어나 전기접전부에 필수적으로 사용해야만 한다. 또한 2007년 유럽의 RoHS규정에 의해 피부에 접촉하는 팔찌, 귀걸이, 목걸이, 반지 등의 디자인 액세서리 제품에 있어서도 종래의 6가 크롬이나, 납, 수은, 카드뮴 사용이 금지되었다. 종래의 산성, 알칼리성, 중성 금도금에서는 주로 시안(Cyan) 기반의 전처리 탈지액이 사용되고 있어 작업환경에도 유해하며 생산성 감소로 이어지고 있다. 이에 전해 금도금 전처리 탈지공정을 개선함으로써 품질불량 20%감소와 함께 작업환경 개선으로 생산성 30%향상을 기대할 수 있다.
