Sword with round pommel discovered in tomb No.39 in the Jisandong tumuli group (M310) is a large sword with a looped pommel enclosing a sculpted dragon head. The sword was produced using different techniques; gold decoration, plating, openwork carving and hammering by using gold and silver. This sword treated conservation work because it has deformation and damages of handle decoration, missing part of sword, and corrosion. Conservation treatment was that foreign material and corroded metal were removed from the surface, and performed to stabilize and reinforce the weakened metal. During the conservation treatment, the object was examined to understand its materials and production method. The result of research, the dragon head inside the looped, amalgam-plated pommel has surface gold decorations. The pommel has a thin gold plate placed over a bottom plate made of copper, which was hammered to create an embossed design. The silver plate-covered hilt, cylindrical in shape, has an openwork lattice design. The steel blade is single-edged. Finally, the locket of the sheath has an embossed design also created through hammering on a thin gold plate placed over the copper bottom plate.

This study presents the results of conservation treatment and research on a folding screen with embroidered classical Chinese characters "壽" (su) for longevity and "福" (bok) for good fortune in various scripts. The project was conducted as part of the program for supporting overseas Korean galleries in 2016. The present mounting of this ten-panel folding screen was difficult to identify as it had previously been remounted in a modern style. However, clues to the original mounting were discovered during the conservation process. It was revealed that the folding screen was decorated with colors frequently used in Joseon-period, such as teal silk at the top and bottom of each panel and a violet frame. These features provided clues to the original mounting of the folding screen, of which only a few elements have survived. Since this study analyzes only case of one folding screen, further research is required to reveal the method of mounting folding screens applied during this same period.

Namwon Singyeri Maaeyeoraejwasang (Rock-Carved Seated Buddha Statue) is composed mainly foliated granite and is different metamorphic grade and weathering degree on rock location. As the results of deterioration evaluation, upper part of the buddha statue was estimated that granularity decomposition was serious and rock strength was lower than lower part. Furthermore organism assessed most effect of among weathering factors. Chl. a amount of organism species were calculated $0.2{\mu}g/cm^2$ of crustaceous lichen, $1.1{\mu}g/cm^2$ of foliose lichen, $2.3{\mu}g/cm^2$ of bryophyte. Organism was taken treatment in order of amount of Chl. a and pre-cleaning, dry cleaning, wet cleaning in sequence. It should be establish conservation plan that strengthening in consideration of lithology characteristics and setting in good condition environment to conserve long-term of Maaeyeoraejwasang.

The Bayon style Avalokitesvara statue from the $13^{th}$ century Angkor period is on display at the Cambodia Angkor Conservation Office. This statue is composed of dark green felthspathic greywacke, the surface of which has been shown light brown discoloration, detected calcite crystallization. As a result of condition assessment, the statue was damaged due to overlap scaling and cracking. Ultrasonic tests have investigated remarkable physical weathering area, flaking and fragmentation in lower velocity. The physical condition of the statue requires a conservation method that improves the binding power. To protect against salt weathering and to ensure physical stability, new conservation material composed of mixed ethyl silicate and sandstone powder similar to that composing the statue was created. The material affected by damage was removed and replaced with the new conservation material.

In this report the practical case of Viking ship's conservation in Denmarke specially among the Eurpoean nations is introduced. The contents of it are summarized as follows :From 1957 to 1962 the Danish National Museum Salvaged five Viking ships from the bottom of Roskilde Fjord, Which were composed of the pieces of timber whose surface was soft because they had lain on the sea bed for about a thousand years. Excavation had been carried out in the same way as in the field by driving down a sheet piling around the wrecks and pumping the water out. These pieces of the wreck ships were packed in airtight plastic bags one by one to be transported for Brede and then immidiately had to go through the treatment for conservation. The conservation treatment process for the pieces includes three steps ; the preliminary process prior to the hardening treatment, the hardening and the assemble of the ships. In the first step ; the preliminary process, all remains of mud and shells from the fjord bed are washed off, and measuring followed ; every single piece of wreckage was drawn so that the form and size of the piece, nail holes, and breaks were registered before conservation. In the second ; the hardening treatment step, the pieces of the woreckage were filled with P.E.G. This Polyethylene Glycol method was the best to handle in the subsequent mounting of the ships in the museum. In the final, the Glycol-treated pieces were pieced together to spips with support of a system of reinforcements. They were to fit in place after corrections of the form were made several times.

More than 200 objects selected for the newly-opened Kimhae National Museum were treated for conservation. The objects which represent ancient Kaya culture, were mainly composed of metallic such as gilt bronze, silver, copper alloy and iron. The corrosion products on gilt bronze and copper alloy objects were preserved or removed according to their stability. Minimum treatment was done for preserving the original state of the objects. For silver objects and iron objects with silver-plate decorations, silver surfaces were revealed after treatment of corrosion products and treatments to prevent corrosion of silver and iron were done emphatically. For iron objects, which were stabilized, the original shape of objects was restored and acrylic coating was applied to prevent further corrosion. For the objects which were being corroded, 2-step de-chloride treatments were undertaken. The first step was immersing the objects in a solution of 0.3M sodium hydroxide and the second was the pressure de-chloride treatment using borax-distilled water. The main purpose of those treatments was to get rid of the causes of corrosion. Besides, conservation treatments for potteries, making of special mounting board for exhibition and amendment of various modeling were done too.

Outdoor sculptures of modern art works are being damaged and deteriorated as they are exposed to the outdoor environment due to the nature of exhibition in the outdoor environment, but secure of basic data through the measures for conservation and advanced researches still remain in the early stage. The surface of "Conversion" which is exhibited in the Busan Cheonmasan Sculpture Park has been exfoliated and deteriorated due to outdoor exhibition for a long time, so systematic conservation and management of works are considered necessary. Prior to the conservation and management, this study conducted observation of cross section, analysis of inorganic components, FT-IR, Raman and Py-GC/Mass analysis to examine the nature and type of paints used for the work through a scientific analysis. As a result of analysis, paints used for the "Conversion" include paint mixed with silvery aluminium powder and white pigment, reddish paint mixed with toluidine red, bluish paint that mixed prussian blue and titanium white and mixture of phthalocyanine blue and titanium white. The result is expected to be used as basic data for selecting materials necessary for conservative treatment of and establishing a plan for conservative treatment of the "Conversion".
