The purpose of this study is to provide the methods of preservation for paper, microfilm, digital media. First of all, for acidic papers produced in 19~20 centuries, this study evaluates and analyses deterioration and factors causing deterioration. For book, also, environmental condition for preservation, and a preservation mechanism through acid-free procedure were suggested. Second for microfilm, it emphasized physical and chemical properties, oxidised substance during developing film, materials related to preservation. Third, for digital storages, storage conditions and needs, such as life-cycle and capacity were introduced.

The bisphenol A epoxy resin currently used for the conservation of stone cultural heritage items is known to suffer from yellowing discoloration. In order to mitigate this yellowing and explore the availability of more diverse materials for the conservation of stone cultural heritage items, a hydrogenated Bisphenol A-based epoxy resin was prepared and compared with the epoxy resin currently used in the conservation treatment of stone cultural heritage items. The newly prepared epoxy resin showed improved physical properties relative to the existing materials, especially in terms of tensile strength, adhesion, and machinability, while the yellowing discoloration was reduced by a factor of roughly five to eight. The results suggest that epoxy resin could be used as a stable material for the conservation treatment of stone cultural heritage items, most of which are located outdoors.

In this paper, conservation treatment processes for the wooden furniture in the Presidential Archives are introduced. Conservation treatment strategies for modern wooden cultural heritage have been increasingly studied. The current study uses materials similar to those used by the existing conservation treatment method. Material analysis showed that the chair(Lee136-2) and desk(Yun37) in the Presidential Archives are made of Dipterocarpaceae, and both are coated with two layers of varnishing. FT-IR analysis showed that the varnish has a similar spectrum to that of a nitrocellulose-based lacquer(Lee136-2) and top coat(Yun37) and confirmed that a synthetic material was used. Pollutants had adhered to the surface of the wooden furniture and it was also in structurally unstable condition because of cracks and damage to the varnish and wood. Therefore, a conservation treatment was carried out to restore the damaged areas to their original appearance using similar kinds of materials, based on data obtained by materials analysis.

Apical sealing with proper retrograde filling material and technique is the key factor for successful apical surgery. In order to provide impeccable apical sealing and healing, various mechanical and chemical characteristics of retrograde filling material is required. MTA has been used as the gold standard of retrograde filling due to its unprecedented advantages. As MTA has long setting time and difficult handling properties, premixed putty type bioceramic material has been newly developed. For efficient retrofilling with premixed putty type biocreamic material, 'Lid technique' was also proposed. The following cases present apical surgery using newly developed premixed putty type bioceramic material with Lid technique.

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.
