This is a brief study on the influence of fumigation (using mixed gas of methyl bromide and ethylene oxide) on old paintings. Fumigation is principally used to prevent biological damage of objects. Thirteen objects, including old colored map from Chosǒn Dynasty and some paintings, were selected for this research. Before and after fumigation, color measurements were made and changes of pH value were measured. The result is that the fumigation did not affect on discoloration of colored area and acidity of paper, as far as the standard of application(such as concentration of gas, exposing time and ect.) of fumigation was kept.

This study conducted scientific analysis and conservation treatment on four suits of armor and two helmets from the collection of the National Museum of Korea. Based on the findings, it identified structural characteristics of armor from the middle and late Joseon Dynasty. Since a suit of armor is made of composite materials consisting of both organic and inorganic elements, conservation treatment was conducted to the extent that the stable condition of each material remained unaffected by the other materials. The process took place in the sequence of investigation and analysis, removal of contamination, stabilization and reinforcement, repair of damaged parts, and storage. The armor and helmets had suffered severe damage, but were safely repaired and partially restored through the conservation treatment. The findings from the conservation treatment revealed the materials used and structural characteristics of the armored skirt from a two-piece set of armor from the middle Joseon period and for the two suits of overcoat-style armor, suit of vest-style armor, and helmets from the late Joseon era. It also allowed the investigation of the production methods of the armor and helmets.

Among about 500,000 characters in metal types in National Museum of Korea, this study conducts a statistical analysis of 62 metal types from the early Joseon Dynasty, including 33 gabinja (甲寅字) types and 29 eulhaeja (乙亥字) Hangeul types by examining the shape, measuring the specific gravity, and identifying the components based on previously-studied Joseon metal types. Among them, 33 gabinja types and 24 eulhaeja types were made of two-component bronze (copper and tin) (Group A), and four eulhaeja types were produced with three-component bronze (copper, tin and lead). (Group B), and one eulhaeja type was created with two-component bronze (copper and tin) with a high tin content (Group C). By comparing with imjinja (壬辰字) types of the late Joseon Dynasty based on multiple statistical analyses of type components, this study confirms that late-Joseon types have low copper content and high zinc and lead content, and therefore it may be possible to distinguish between the types of early and late Joseon Dynasty.

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. Howeve, 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 win take charge of conservation and care of cultural properties, that is, an organization which will consist of scientific keeping facilities and expert personnel (conservation scientists) is needed immediately.

For the conservation treatment of the Central Asia mural painting which is to be exhibited in the new museum in Yongsan, we analyzed the pigments used in this mural painting and examined to identify the species of the straw in the wall. We also analyzed the species of the wood of the wooden protective frame and the material of the paper in it, in order to review the material and technique of the conservation treatment performed before the mural painting had been brought to the National Museum of Korea in 1916. The results were as follows: the black pigments of Bon4075 and Bon4078 is carbon(C); the white pigment on the background is gypsum[Ca(SO)₄(H₂O)₂]; the red pigment is lead oxide(Pb₃O₄) and hematite(Fe₂O₃) etc. The straw, which had been mixed into the wall to prevent the wall from cracking, was proved to be either wheat straw or oats straw. The wooden protective frame, which protects the mural painting now, was proved to be made of Salix, Populus, Cryptomeria japonica and pine. The paper discovered in the frame was proved to be made of the bark of a mulberry.

The residual lipid analysis has been used for finding out the information related to the life style of ancient people. In order to achieve this goal, it must be precedented by building a database of residual lipid analysis of the present creatures. In this study, we performed residual lipid analysis of a cow and a dog, which were the present samples. We hope the results of this study will be a primary reference for the future analysis of archaeological materials.

런던의 과학박물관은 영국 뿐만 아니라 세계 과학기술의 역사를 한 눈에 볼 수 있도록 지하 2개층과 지상 5개층에 꾸며놓고 있었다. 1층엔 동력ㆍ우주분야, 2층엔 재료변화, 3층엔 화학산업ㆍ인쇄, 4층엔 광학ㆍ항공분야 그리고 5~6층엔 의학관련 분야로 분리되어 전시ㆍ소개하고 있었다. 특히 지난 7월에 개관한 WW관엔 2000년대의 과학기술방향과 돌리를 탄생시킨 영국의 생명공학발전상 그리고 미래의 디지털기술에 관련된 전시물들이 진열되어 있었다.

The purpose of this research is to investigate the participant satisfaction of public educational programs being carried out in Natural History Museum and the contribution of these programs to normal school education and to suggest an improved framework for public education programs in Natural History Museum. For this study, we choose Seodaemun Museum of Natural History in Seodaemungu, Seoul, in which more than 30,000 students have participated in the educational programs for the last 6 years. This museum has been providing more than 60 science education programs every year. Based on a public census among participating students and accompanying parents, we investigated the satisfaction ratings of education programs provided by Natural History Museum and their contribution to school science education. The result of this study can be summarized as follows: (1) It is desired to have the education program contents well connected to the exhibits of the Museum and to increase time for experiments and practice. (2) It is required to improve the ease of access and to enhance the public awareness about the program itself. (3) The biggest consensus among participants is that the education programs by Natural History Museum should be focused on strengthening the research ability and scientific attitude rather than on acquiring knowledge, which will contribute to school education more significantly in the end.
