In Katap-ri, South Korea, potteries and roof tiles are excavated with the assumed raw materials. Using NAA, the provenance of these cultural remains was examined among the neighboring others, and the correlation the assumed raw materials with potteries and roof tiles also was examined. From the results of statistics it is concluded that this cultural site is distingushed from others by several trace elements, Ba, Cr, Sc, Yb, Eu, and Rb with 93.2 % accuracy. Also it turned out that the assumed raw materials wasn't raleted to potteries and roof tiles with 96.3% accuracy.

지난 10월 문화재청과 KBS, LG전자가 공동으로 기획한 '다시 만난 우리문화 유산전'은 국외문화재를 울트라HD 영상으로 촬영하여 고화질의 디스플레이를 통해 국민들에게 국외의 문화재를 소개하였다. 국외문화재를 만으로 구성된 전시는 국민들에게 지금까지 볼 수 없었던 유물에 대한 정보와 이미지를 제공하여 국외 문화재에 대한 국민들의 관심을 이끌어 냈다. 하지만 관람 방법과 정보 전달적인 측면에서 한계가 있었다. 따라서 '다시 만난 우리 문화 유산전'의 사례를 살펴보고 관람 방법과 정보전달의 방법에 대한 보완점을 찾아야 한다. 앞선 전시에 대한 보완점을 전시에 적용한다면 국외에 있는 우리 문화재에 대한 지속적인 관심과 접근성을 높여 국외문화재에 대한 꾸준한 전시를 유도할 수 있을 것이다 또한 국외문화재를 학술적으로 폭 넓게 사용되어 활발한 연구가 진행되고 전시뿐만 아니라 다른 분야로의 확장을 이끌 수 있다.

Amber has been used as gemstones and artifacts from the period of the Three Kingdoms or earlier, which are discovered in the process of excavation now. It is, however, very difficult to discuss the importing route and circulation of amber because there are no informations available on the provenance. In this study, we acquired the IR spectra of ambers originating from 5 different locations. We also monitored the change of characteristic IR peaks by artificially aging the ambers under heat, light and heat with oxygen, respectively. As the aging proceeded, the intensity of C=O band and O-H band increased, however, the bands related with C=C bond decreased. There needed some modifications in the discerning scheme because some peak disappeared with aging; yet, it was still possible to discern different ambers largely. Therefore, it is expected that the scheme can be used practically by appraising its applicability to the real amber relics excavated.

This study attempts to identify whether there were preferred wood species or any required properties depending on the use of wooden objects by comparing wood species analysis results of wooden objects, which are classified specifically by their uses like comb, wooden tablets, containers, etc., excavated from Haman Seongsansansung mountain fortress, which is the archaeological site of the Three Kingdoms era and those excavated from archaeological sites in Gyeongsang province considered to be the similar era of Haman Seongsansansung mountain fortress site. Wooden tablets and combs show the preferred species clearly and containers preferred wood species with the mid-ranged strength and the resistance against moisture migration.

The resistance for atmospheric corrosion of the conventional 5 epoxy resins (Araldite rapid, Araldite AW 106, Araldite SV 427, Devcon, and CDK), those were used to restoration of the iron relics, were investigated in this study. Temperature, UV light, and water were chosen for the factors of the atmospheric corrosion. The drastic voluminous changes of the epoxy resins were found at the temperature range between $40^{\circ}C$ and $70^{\circ}C$ After UV exposure, the colors of the epoxy resins were severely changed. In case of the indoor exposure the chroma value(${\Delta}E$) of the resins were less than 2, which showed a little changes of the colors. The result of the water contact angle test was Araldite rapid>AW 106>Devcon>SV 427>CDK. Although the contact angles of the resins were reduced by UV exposure, SV 427 was stable comparatively.

In order to identify the application techniques of wooden lacquerware artifacts, optical/polarized light microscopy, Fourier transform infrared (FT-IR) spectroscopy, and scanning electron microscopy (SEM) equipped with energy dispersive X-ray analysis (EDX) were conducted on the lacquer films of 61 wooden lacquerware artifacts excavated from the Imdang-dong site, Gyeongsan, Korea. Powdered soil, soot, and charcoal were used as a filler for the undercoat, and iron oxide ($Fe_2O_3$) was used as a red pigment. Five different applying techniques were identified for the undercoat according to the composition of the lacquer. Eight different application techniques were identified for the final coat (on the middle layer and surface layer). Totally seventeen application techniques were identified based on the combination methods of the undercoat and finalcoat. Consequently, the undercoating techniques of Imdang-dong lacquerwares were found to be similar to those of lacquerwares from excavated in other provinces. However, the use of iron oxide as a red pigment at Gyeongsang province is very characteristic compared with others.

The iron culture have been studied mainly about the initial aspect and the growth of polity grossly on the level of the south Korea or the Yeungnam province. But the iron culture is necessary to study by diachronic and regional approach about the artifact

In order to understand the influence of light artifact discoloration, priority must be given to the reaction characteristics of the light the materials constituting the product. In this study, we focus on two representative medium, animal glue and linseed oil which constitute the colored layer of the painting relics. This study is based on an accelerated degradation test using two types of light emitting diods (LEDs) with different wavelength characteristics. In the experiments, discoloration appeared markedly in the animal glue and linseed oil under accelerated aging test conditions using Blue LED. Among the two types of LEDs, the degree of discoloration of the material was much higher with the Blue LED having the total radiation flux (mW). This indicates that the discoloration of painting artifacts such as animal glue and linseed oil is more significantly influenced by the total radiation flux (mW) of the light source than the total luminous flux (lm).

We performed the non-destructive analysis of objects excavated at the Tomb of Mich’un-ri in Ch’ung-won. We analysed components using of Energy Dispersive X-Ray Micro-Fluorescence Analyzer. Glass bead inlaid with silver was classified as K2O-CaO-SiO2 type of glass. Purity of silver inlaid in the surface was verified above 97%.All small ear-ring were made by rolling up gold broad to a bronze wick. The composition ratio of Au : Ag has significantly higher 87 : 11 than bigear-ring. As a result of composition analysis of a welded part with big ear-ring, it contained the more Cu, Hg contents and the less Au, Ag contents than the surface of big ear-ring.

The most important aspect in preserving ancient paintings is to return the painting to the original state and conserve it in the original state. One traditional recovering method is the use of frame, for which scientific analysis such as X-rays, infrared and microscope are used and materials are carefully selected. Arhat, a Buddhist painting of Koryo Dynasty, one of the Korean National Museum collections has lost its original shape. With conservation treatment, the cause was found, that is to change frame scroll method to mounting method. In the main body, pre-analysis and conservation method of Arhat will be introduced.
