A scale Armor is usually excavated in a scattered form weakened by corrosion after its burial. Therefore, they should be brought into the indoor in a safe environment for the on-site conservation treatment as it was excavated. They should be placed on a stable support with a reinforced base in the indoor treatment. In this process, the bottom surface which can not be observed after the conservation treatment is placed for a record by actual survey and photography. But this method had a limit on figuring out the whole aspects of the artifact. For compensating the defect, duplication of the artifact was considered as an alternative method for the previous two methods in the case of conservation of the scale Armor from Jinyoung 2-Area, Gimhae. Neck guard was excavated in a distorted form by the earth pressure, and was hard to recognize the original shape. However, whole real material of its original form was secured through the combination of each duplicated lamellae. Throughout the application of the duplication technique in the process of conservation of scale Armor and neck guard, it could secure the real material of the bottom surface and elevate the understanding of the artifact. Moreover, a constitution of the armor could be identified more effectively.

Gwanghwadang-Wonsam was designated as National Folklore Cultural Heritage No. 52 in 1979, it is in good condition. However, a problem is the attached a phoenix insignia badge that did not exist when it was designated recently. As it became known as the only purple Wonsam artifact with "phoenix insignia", raising the need for its conservation. In this regard, scientific analysis was required to correct misinformation about designated cultural assets and restore the original designated state by analyzing the history of the Gwanghwadang-Wonsam, other relics of the phoenix insignia and its making design patterns. An X-ray fluorescence analysis was used to confirm that the Phoenix insignia's metal threads were titanium-plated silver. Phoenix insignia using titanium-plated gold thread was not identified in Gwanghwadang-Wonsam photographs in 1986, and the TiN-type membrane plating method was used in various industries in the 1990s, which can be estimated to be attached in the early and mid-1990s. Especially, the scientific analysis results from the X-ray fluorescence analysis in this study provide key evidence for conservation processing. This study demonstrates the importance of investigating relics and similar artifacts in the conservation process of inherited relics and as a precedent for restoration that corrects misinformation about designated cultural properties.

A wooden rice chest in National Museum of Korean Contemporary History was colored by black lacquer but it was degraded and fallen apart partially. The condition of the paint of front and left sides were relatively fine, but the coat of the top, back and right sides were exfoliated. The legs at the bottom of the chest were severly degraded and turned whitish. After condition checking flakes and deterioration of film, the conservation treatment was undertaken with cleaning surface. Wet cleaning was conducted that area had lots of dust area. Apply watery animal glue to degraded lacquer layers. The legs were exfoliated a lot, so applied watery animal glue several times. Other side of rice chest except Gaepan, that was not felt sense of difference, colored centrally Gaepan.

The purpose of this study is to propose an effective operating method of a power generator used by the Emergency Power System in case of a simultaneous fire and of the limitations of the interlock system the power supply from the emergency power generator. On the Emergency Power System with Reserved Fire-fighting Power (RFP), in case of an overload, the collective control Emergency Power System signals the main circuit breaker to shut off the supply to the emergency load, leaving the supply to the firefighting load uninterrupted to the end. The sequential control Emergency Power System signals the firefighting power supply to shut off the fire stage of the emergency load and continues to monitor the power supply. If an overload happens again from increased firefighting load, the sequential control Emergency Power System sends a secondary signal to shut down the second stage of the emergency load.

In this paper, conservation treatment processes for the wooden furniture in the Presidential Archives are introduced. Conservation treatment strategies for modern wooden cultural heritage have been increasingly studied. The current study uses materials similar to those used by the existing conservation treatment method. Material analysis showed that the chair(Lee136-2) and desk(Yun37) in the Presidential Archives are made of Dipterocarpaceae, and both are coated with two layers of varnishing. FT-IR analysis showed that the varnish has a similar spectrum to that of a nitrocellulose-based lacquer(Lee136-2) and top coat(Yun37) and confirmed that a synthetic material was used. Pollutants had adhered to the surface of the wooden furniture and it was also in structurally unstable condition because of cracks and damage to the varnish and wood. Therefore, a conservation treatment was carried out to restore the damaged areas to their original appearance using similar kinds of materials, based on data obtained by materials analysis.

경산 임당유적에서 출토된 목제 갑옷틀은 수침된 상태로 출토된 목제유물로 재질이 매우 취약하여, 대기 중에 노출되면 급속도로 건조가 진행되어 곧바로 수축 변형이 일어나 유물로써 가치를 잃어버리게 된다. 특히 목제 갑옷틀은 오랜 매장기간동안 목질부의 분해가 많이 진행되어 재질이 취약할 뿐 아니라 원통목을 가공한 것이어서 건조 과정에서 수축변형이 발생우려가 높다. 따라서 목제 갑옷틀은 건조변형이 적고 치수안정화가 우수한 처리법을 적용하여야 한다. 따라서 목제 갑옷틀은 t-butanol 용액을 용제로 PEG#4000 40%로 함침 전처리 후 진공 동결건조법으로 보존처리 하였다.

The Conservation Science Laboratory of the National Museum of Korea had drawn up the list of conservation treatment priority according to the artifact status in the collection and performed conservation treatment based on the priority list since 2006. This paper introduces the restoration process of the lost part of a black teacup(Sindo 1961) with newly developed restoration material. Part of the peeled off glaze was analyzed with LIBS and SEM-EDS analyser to find out the glaze ingredients that make the unique pattern of black teacup.

We conduct the conservation treatment for the wooden well bucket excavated from civilian remains in Siji-Dong, Daegu. This bucket was in very poor condition, having been buried for a long time; thus, cetyl alcohol was used for the conservation. After replacing the water inside the wooden material with alcohol, the density of the cetyl alcohol was increased by 20, 40, 60, and 80% and immersed for two weeks at each step. After completing the immersion procedure, the remaining cetyl alcohol was removed, and the bucket, dried under normal atmosphere.

Remarkable features, such as neck guard and plate designed the shape of a duck, are identified in the process of conservation for the plate armour excavated from the No. 2 tomb, Daeseong-dong, Gimhae. We considered that should be careful for treating this kind of artifacts, especially when restoring to its original. For this purpose, we thoroughly studied the endurance of materials for restoration and applied the techniques in reference to the traditional method.

국가R&D사업의 추진결과와 활동현황에 대한 종합적이고 다각적인 분석을 위해 1999년도부터 매년 모든 국가R&D사업에 대해 주요 연구 성과인 논문, 특허, 기술료 등에 대한 국가R&D 조사분석 자료 수집이 실시되고 있다. 국가R&D 표준정보 수집을 위해 2003년도에 '국가연구개발사업 종합관리시스템(CORDI, 현재 SIMS)'이 구축되었고, 매년 국가R&D 조사분석 자료들의 수집 분석이 실시되고 있으나, 전자기록의 속성을 갖는 국가R&D 조사분석 자료, 특히 조사분석의 검증자료에 대한 장기적 보존을 위한 관련 연구는 전무한 상태이다. 따라서 본 연구는 국가R&D 조사분석의 검증자료에 대한 장기적 보존과 나아가서는 평가의 활용 및 정보 시스템간의 상호운용성을 높이기 위한 국가R&D 조사분석 검증자료의 보존 메타데이터 모델을 제안한다.
