The purpose of this study are to examin the level of temperature, relative humidity and pollutants at stock rooms in National Archives and to provide fundamental data in order to protect damage of archives. The survey of indoor air quality(IAQ) in stock rooms was performed in Busan National Archives in August and December 2007, and collected basic data, on level of them at stock rooms in National Archives that were published. The temperature and relative humidity in stock rooms were within the terms of national law of the public archives administration. The concentration of PM10 in stock rooms in National Archives exceeded 50 ㎍/m³, which is the guideline of national law for the public archives administration. The concentration of CO, SO₂, NO₂, O₃ and Formaldehyde in stock rooms did not exceeded the guideline of national law. The concentration of total volatile organic compounds was shown to exceed the guideline of natioanl law. Therefore, we suggest that a national plan for the management of IAQ at stock rooms in National Archives should be established through a long-term, continuous investigation

The purpose of this experiment was to find out the effects on metal corrosion of 2 types of tree, 7 types of wood based products and 4 types of cement that is currently being used as internal museum materials. By using the Oddy test as a corrosion test, with the materials that are used in the museum and the metal test pieces(Gilding, Silver, Iron, Bronze, Copper) are exposed in a high temperature( 60℃ ) and humidity for 28 days. After 28 days, we compare and analysis the difference between the metal test piece that was used before and after the test. We found that gilding and bronze did not occur corrosions on the surface but iron(Fe)and copper(Cu) also silver(Ag) had corrosions on the surface in different forms.
