The responsibility of keeping and caring of unearthed cultural properties belongs to the National Museum according to cultural properties protection law (law no. 3644). So unearthed cultural properties are possessed by the museum after going through the regular course. Number of those cultural properties is increasing swiftly. Every year more than ten thousand units of cultural properties are unearthed. The number of unearthed cultural properties is expected to increase in the future. However, the keeping facilities of the National Museum are already over-saturated. So many unearthed cultural properties are being entrusted to university museums that have bad facilities and few personnel.. It makes many problems including inadequate caring. More pressing problem is that those cultural properties are not under the protection of scientific conservation processing and caring. The reason is that there are so few conservation scientists in Korea. There is no independent department of conservation science even in the National Museum, where only five members are working as conservation experts. To solve those problems, new system and organization which will take charge of conservation and care of cultural properties, that is, an organisation which will consist of scientific keeping facilities and expert personnel (conservation scientists) is needed immediately.
