The museum of Chonnam National University unearthed and researched an Andong tumulus located in Gildu-ri, Podumyeon, Goheung, Jeonnam in March 2006, and many remains were excavated from the tomb. The Conservation Science division of the National Research Institute Cultural Heritage was asked to deal with about 100 pieces of relics with gilt bronze, including a Gilt-Bronze Cap, and ironware remains from the excavated site for the museum of Chonnam National University and urgently dealt with the excavated site for 4 days from March 27 to March 30, 2006. All of the remains were dealt with and cleaned up in this way, were moved to the National Research Institute Cultural Heritage, and have been under a conservation treatment until now. In this study, excavated conditions, the handling of the excavated site, the conservation treatment process until now, and the forthcoming conservation treatment plans will be examined specifically focusing on the Gilt-Bronze Cap with gilt bronze among many other remains.

There is a necessity of re-research about Geumgangsaji temple site as reviewed recently confirmed typical temple arrangement of Baekje. The purposes of this study are, determine that building remains and layout patterns using Ground Penetrating Radar, and identify that the location and terrain changes of Geumgangsaji using aerial photographs and a numerical map by GIS. In the GPR result, it was confirmed that new building sites in the west and the north area which in Geumgangsaji is more wide. In addition, it was found that the temple is located on stable river terrace with low soil loss. And this site has spontaneous drainage system for the optimum position.

The pupose of this study was to identify the material characteristics, firing environments and making techniques for the jar coffins from the Oryangdong kiln site and the Ungokdong tomb site in Naju. All jar coffins had very similar physical, mineralogical and geochemical characteristics, although it was excavated from the different sites. The wall thickness of the jar coffins was about 2.3 to 5.3 cm. Under the microscopy, the jar coffins include a large quantity of various quartz with some microcrystalline and showed partly orthoclase and biotite. It is presumed that the mineral sherds added to maintain the thick wall and to control the percentage of contraction during drying and firing of jar coffins and it has contained about 11.4 to 19.8 %. Firing temperature of the jar coffins is estimated as 1,000 to $1,150^{\circ}C$. Also, all jar coffins and soils show similar geochemical behavior of elements and clay-mineralization degree within the site. This indicates making that the soil is probable to be a raw material of the jar coffins. But it shows different characteristics in major elements of soils which is collected at the kiln floor and the trench region of the Oryangdong kiln site because of the lack of quartz and feldspar in the soils. Therefore, it can use of the jar coffins making clay, if it goes through a simple special process such as mixing temper.

In this study, the physicochemical properties of 21 wall fragments and rooftile pieces excavated from Jeseoksa Dump-site were analyzed, and the possibility of heat exposure, such as the fire reported in the literature, was investigated by estimating the firing temperature. From the results, it was estimated that the rooftiles were composed of refined materials, and the walls were composed of materials having different particle sizes depending on the layer. Unlike ordinary rooftiles and walls, they exhibited an uneven surface with traces of bloating phenomenon in the cross section. It was estimated from the blackening of some portions that firing was not performed in a controlled state in a constant firing environment. In addition, the estimated firing temperature showed that the non-overfired rooftiles had endured a firing temperature of 900℃ or less, but the over-fired samples were subjected to a temperature of 1,000℃ or higher and were fired at a temperature higher than the manufacturing temperature at that time. Additionally, the rooftiles probably became defective during firing or molding at the time of production, but the non-overfired rooftiles exhibited an intact shape and showed the possibility of heat exposure due to fire. Therefore, the analytical results of this study confirm that the defective architectural components damaged by the fire, as reported in the literature, were discarded in the Jeseoksa dump-site.
