  • The area of conservation treatment of the bronze helmet of the ancient Greece, treasure No. 904, which Sohn Keechung (1912 to 2002) received as an extra prize for his winning the marathon in the 1936 Berlin Olympics deteriorated and as a result crack and discoloration occurred. Its nose guard hung downward due to the crack of the bonded area of upper end. Therefore, conservation treatment of the helmet was conducted again. The nose guard was separated from the body. Stabilization and consolidation treatment of them was made and then they were joined again. The cracked and missing areas were reinforced with woven glass fibers, and the nose guard was reinforced with woven glass fibers and Ti plate after the bonding. The joined area of the nose guard was carved with the same pattern as that of the surrounding area and its color was adjusted to be the same as well.

  • The aim of this in vitro study was to evaluate the cleaning efficacy of various irrigation methods in the mandibular mesial roots. The forty five mesial root canals were shaped by Profile .06 instruments to apical size #30 and irrigated with 5ml of 3.5% NaOCl. The teeth were divided into 3 groups and irrigated finally for 1 minute; Group 1: syringe irrigation. Group 2: ultrasonic irrigation. Group 3: RinsEndo irrigation. After histological processing, the cross sections of apical 1, 3, and 5 mm level were examined with an optical microscope. The cleanliness values of canals and isthmuses were calculated and analyzed by Mann-Whitney U test. 1. There were no significant differences in both canal and isthmus cleanliness between syringe irrigation and ultrasonic irrigation except 5 mm level of isthmus. 2. RinsEndo irrigation had significantly higher canal cleanliness values than syringe irrigation at 1 mm and 3 mm levels (p<0.05). Also, RinsEndo irrigation had significantly higher isthmus cleanliness values than syringe irrigation at all levels evaluated (p<0.05). 3. There were no statistical differences in both canal and isthmus cleanliness between ultrasonic irrigation and RinsEndo irrigation except 3 mm level of canal. From this study, RinsEndo irrigation can be useful as an additional irrigation procedure.

  • The bronze bowl with lid excavated from Eunnyeongchong Tumulus in Gyeongju had been united in the past and then damaged. We removed deteriorated adhesive and other impurities from it and reunited it. Some fragments of the artifact has been lost; in particular, only half of the whole main body remains. Therefore, it needed restoration treatment for exhibition and conservation. The lid, relatively much part of which remains, was treated with the method that could easily detach the restored part; the main body with much restored part was united using epoxy resin so that the restored part could well bear the weight of the artifact.

  • 보존 처리된 유물은 경기도 하남시의 발굴현장에서 수습된 도토기로, 박물관의 소장유물로써 지역사(地域史)의 한 단면을 보여줄 수 있는 자료로 활용 가능성이 있을 것으로 판단되었고, 유물의 상태를 고려한 보존처리작업이 계획되었다. 보존처리작업은 가역성(可逆性)과 경제성에 중점을 두어, 박물관에서 이미 책정된 보존처리예산의 한도 내에서 선택할 수 있는 알맞은 약품과 재료를 선택하여, 복원작업이 필요한 부위 역시 추후 재처리작업이 필요할 때 해체가 용이한 기법을 이용하였다.

  • 치아 외상은 크게 fracture와 luxation injury로 분류된다. 이 중에서 영구치의 root fracture는 외상의 0.5~0.7%를 차지하는 것으로 조사되고 있다. 호발부위로는 상악 중절치가, 나이로는 11~20세에서 호발하여, 이보다 어린 나이에서는 alveolar socket의 elasticity 때문에 fracture보다는 luxation 쪽으로 많이 발생하는 것으로 보고되고 있다.(중략)

  • In this paper, key features of an excavated submarine article and general process of its conservation will be introduced. First, the conservation process of removing salt from an excavated submarine article was done by desalting stage, and the X-Ray photographing was done for its inner and outer damage detection. The process of making a restoration mold with the beeswax for the broken part, making restoration material with fillers and grinded broken pieces of earthen ware have similar color and quality, and color matching distinguishable for the naked eye after the whole conservation process have been finished.

  • The bronze incense burner, discovered in Chungung-dong, Hanam, Gyeonggi-do in 1971, is a hanging incense burner dating from the Goryeo period. The incense burner was covered with a thick layer of clay. The object was in a severely deteriorated state, affected by bronze disease which resulted in extensive corrosion. Numerous cracks were present across its surface, and some parts had been broken off. To preserve and display the bronze incense burner in a stable condition, deposits of foreign material were removed from the surface, and the weakened metal was strengthened. Cracked and broken areas were reinforced using woven glass fiber, followed by the application of epoxy resin to restore the shape. To investigate the method of production, a chemical analysis was performed, and the microstructure was examined. The chemical analysis revealed that the body of the incense burner as well as the ear, loop, lid and the knob were cast in a ternary alloy of Cu-Sn-Pb. Moreover, copper nails with high copper content were used to securely join the ear to the body of the incense burner. The microstructure was mainly α-phase, and non-intermetallic inclusions composed of Cu and S were detected.

  • The flower type ornament of the gilt bronze palace-type sarira reliquary among those sarira reliquaries of the East Pagoda at the Gameunssa Temple Site, which is the Treasure No. 1359 owned by the National Museum of Korea, was separated from the sarira reliquary in November 2010, thus conducting conservation treatments to be done on two items including the gilt bronze palace-type sarira reliquary during the period of March-October 2011. Those conservation treatments were carried out by following the process of removing the coated areas having excessive gross and bubbles, re-coating with Incralac, and then strengthening both the cracked areas and the separated flower-type ornaments with woven glass fiber after rejoining. For those areas where removal of gloss and bubbles at the coating and adhesive areas was not possible, the gloss and bubbles were made less perceivable through matting treatment and coloring.
