Analysis of Flat board-shaped Lacquer ware excavated from Daho-ri was conducted. The result of species identification is identifed as Pinus spp. As a result of microscopic observation, lacquer fragment is consist of 5 layers and its thickness is about 100 ㎛. Infrared spectroscopy of the lacquer ware revealed that they had a very similar absorption band as refined lacquer, confirming that they were painted with lacquer. Result of Analysis for Circular metal ornament is alloy smelted by tin and lead. It is called Pewter. While The species of wooden objects investigated until now is broad-leaved tree; the species of flat board-shaped lacquer ware is conifer.

Wooden object lacquerware and grass made object excavated were discovered in water. The object can be dry gradually for a long time when it is not kept at water evaporation. Wooden area of wet lacquerware wet organic materials mmersed kept lacquer only on the exterior after being decayed, and most of grass made object were adhered to the earth. In this study, the author preserved lacquerware and grass made equipment at Dahori Changwon that were relics in the Iron Age by using bees wax, rayon pper and layering technique. And, the author could remove ware from the earth to conserve lacquer and grass made object.

Excavated lacquer wares can be divided into waterlogged lacquer wares supersatuated with moisture and dry lacquer wares with little moisture. This conservation was done with dry damaged lacquer wares excavated from Daho-ri. Lacquer ware artifacts with lacquer fragments and no surface material remaining were processed using the three following methods. The three methods are reinforcing while sustaining three-dimensional form; reinforcing with earth after cleansing so that fragments are revealed due to weak lacquer fragments; and reinforcing the whole lacquer ware or parts by connecting and supporting missing parts with rayon paper, an artificial fiber paper, if the form cannot be sustained only with lacquer fragments.

A scientific analysis was carried out on the 14 pieces of glass beads excavated from the Daho-ri site NO. 6, Changweon. Most of the glass pieces were made of light blue transparent glass with round bubbles aligned in a regular direction. As a result of the SEM-EDS analysis, all the glass pieces turned out to be within the potash glass group (K₂O-SiO₂) and were identified to be the LCA (Low CaO, Low Al₂O₃) series glass, of which the concentration is 5% or below for CaO and Al₂O₃ respectively. In addition, it is presumed that plant materials were refined or a mineral (saltpetre, KNO₃) was used as the raw materials for making potash and also that the ingredient acting as a colorants for light blue color was affected deeply by CuO.

A wooden coffin has been given academic attention in Kaya(伽倻), due to the place the stage of Samhan society appropriately in the development of ancient korea history. Special attention must be paid on Dohang-Ri(道項里) woden coffin, since it is expected to explain the origin of Arakaya(阿羅伽倻) in the region of southen korea peninsula. Dohang-Ri wooden coffin is become generally knowen two types, and complete its unique feature in Chin-Han(辰韓) and Byun-Han(弁韓). Recently the fact that Dohang-Ri wooden coffin is discovered only in the king tombs of Chang Won Daho-Ri(昌原茶戶里) and it is remarkable of political connection between Kuya-Kuk (狗邪國) and Anya-Kuk(安邪國). Various ironware unearth of Dohang-Ri has seen similar to that from Daho-Ri, but it has not bronze mirror be maid Chines, symbol with dignity of social position in the ruling ciass. It seems that political unit of Daho-Ri is advanced sociaity and central force than Dohang-Ri in the Byun-Han. The later of two century, I have a think about wooden coffin changes the wooden chamble of Dohang-Ri and Daho-Ri that it go out of sight at AD.2 century. Becouse of possitive achaelogical sites has not confirm, it request radical interpretaion. I inference to accordingly to the it appearance connected of the wars between the eight country of southen regins in korea peninsula at the first half of AD.3 cencury. Exactly, the politial units of Dohang-Ri and Daho-Ri has concentration of trade in Racdong river(洛東江) and Nam river(南江) water system and that give form to coexistence system of economic and political mutuality.

This study presents an investigation into the conservation process of an iron dagger and scabbard, which are a lacquered scabbard and a dagger inserted in it, excavated in the Daho-ri relic of Changwon by Gimhae National Museum. The bronze dagger whose condition was poor due to corrosion was coated with Incralac, an intensifier, to reveal the surface patterns through a microscope. The lacquered scabbard was removed of foreign substances on the surface and coated with HPC 2%(in water) to protect the film. Applied onto the surface from which foreign substances were removed was Caparol Binder 5%(in water) two to three times to form a protective film and then faced with Korean paper. Once it was fixed in a polyurethane foam in a stable manner, it was turned over to receive the same process on the back. Three layers of Korean paper were attached to the back of the scabbard to support the thin artifact. HPC 2%(in water), which was applied to the scabbard, was also applied to the iron dagger inside for cementing effect. After all the processes were completed, the artifact was put in a transparent acrylic box for future display.

24 wooden objects excavated from Daho-ri were identified into 8 categories such as Quercus spp. (37.7%), Castanea crenata (8.3%), Prunus (8.3%), Ilex (4.1%), Alnus spp. (25%), Prunus spp. (4.1%), Zelkova serrata (4.1%) and Fraxinuse (8.3%). Physical properties of the above high water content, high contraction rate and significant density reduction. As for degradation pattern, observation with polarizing microscope showed significant decrease of double reflection phenomenon in most of the excavated objects excluding vessel compared to other kinds of objects, and observation with SEM showed remarkable degradation of organization structure including the 2nd cell wall of wood. Reagent can be easily penetrated and diffused into the objects with high degradation rate, so it's beneficial to treat them with polymers such as PEG#4000(MW:3,350), but in order to prevent contraction and change in shape, high concentration of Reagent is required in treatment to hold wood organization structure.

Although in Korea there are only three examples of wooden coffins being found in burial mounds - from the Daho-ri, Songhyun-dong, and Munyung tombs, in Japan data on the shape and structure of wooden coffins from the Gofun era is relatively abundant. The wooden coffins of the Gofun era of Japan can be classified into either the dugout log style or the combined boards style according to their method of manufacture. They can also be divided by shape, into such categories as the boat shape, the split bamboo shape, the box shape, and so on. The box shape category can be further divided into the assembled type and the nailed type, according to how the boards are put together. Japanese Umbrella Pine (Sciadopitys verticillata) was favored as coffin-wood in all ages, but during the later Gofun era easily obtained woods such as the Japanese cedar (Cryptomeria japonica) or the Hinoki Falsecypress (Chamaecyparis obtusa) were also used. The coffins found at Daho-ri and Songhyun-dong are similar to the Japanese dugout log style in shape and manufacture, while the king's and queen's coffins excavated at Munyung Tomb are seen to have had direct influence on the appearance of nailed coffins Japan. The coffin in Songhyun-dong 7th mound was originally a dugout log boat. It was probably used for practical reasons such as the bugproof, anti-corrosion qualities of camphor wood, not because of ideological reasons such as in a boat burial (in which the boat takes the deceased to the after world). Because the Changnyong region is inland, where camphor trees do not grow, using an already existing boat may have been the only way to procure a camphor-wood coffin. From historical circumstances, it may be inferred that the camphor trees were imported into Korea from Japan, between which there was much cultural exchange.
