Copper electroforming process has been applied to duplicate Koryo Tripitaka (Taejang'kyong), wooden printing block. Thin copper replica printing plates of 1 mm thickness was successfully manufactured from the printing face (54.5${\times}$25.5 cm) of wooden printing plate. Major processes are (1) silicon rubber replication of the master (2) silvering on silicon rubber (3) copper electroforming (4) separation of copper from the silicon mandrel (5) final coloring by brass plating and trimming. This process has various Potential applications in making thin metallic objects such as plaques, statues, bust and hollow metal objects for jewelry.

In the present study, ventilation flow in the Janggyeongpan-Jeon at Haein temple in case of building rearrangement has been investigated numerically. To achieve more accurate results, detailed shapes such as buildings and the window grills are modeled and tree canopy model is adopted to account for the effect of trees in the computation. Wind velocities as boundary condition are taken from meteorological statistical data. The numerical results show that ventilation flow distributions at Janggyeongpan-Jeon in case of building rearrangement are nearly similar to those before rearrangement.

The present paper is focused on Korea's inscribed heritages, digitization of the Tripitaka Koreana & miscellaneous buddhist scriptures, and public uses of the digital properties in order to describe the Digitization & Popularization of Printing Woodblocks of the Tripitaka Koreana and Miscellaneous Buddhist Scriptures, Memory of the World. The Goryeo Daejanggyeong or the Tripitaka Koreana and miscellaneous Buddhist sculptures refer to printing woodblocks of the Tripitaka(National Treasure No.32), and repositories (National Treasure No.52) where the woodblocks are stored. The woodblocks numbers 1,514 types/81,350 blocks/162,700 pages. Haein temple has worked the digital Tripitaka project 2009-2010 and The project for 2010 will focus on DB correction and modification, improvement of homepage that was made in 2009. For this, the focus was especially put on investigating current status and development plans of the digital Tripitaka project. In popularization of the digital Tripitaka, this study examined the Korea's utilization policy and current situation of knowledge resources about culture, successful cases of digital Tripitaka projects, and popularization strategies. This research can contribute to digitization of other cultural heritages and related researches in the future.

The Koryo Buddihist Canon Printing Wood Blocks are stored in excellent condition for more than 750 years at the Haein-sa Monastery, Hapchon, Kyoungnam. The lacquer coating may be a reason for the conservation of the wood blocks among many reasons. We studied the lacquer coatings and compared these with authentic lacquer sample by several methods including IR and UV spectroscopy and pyrolysis/GC/MSD.

Ventilation performance in the storage hall of Janggyeongpan Jeon has maintained for more than 600 years. Janggyeongpan Jeon in Haein temple has window structure of bi-level ventilating opening which consists of upper and lower window. Also, different size and shape of windows are adopted for various locations of the hall. In the present study, to analyze effect of shape of windows on ventilation performance in the storage hall, various design alternatives were considered. Numerical analysis of ventilation in the storage hall was investigated under the same simulation condition except for the shape of windows. Through the comparison of numerical results for various window designs, it was evaluated that the current windows shape gives best ventilation performance.

Tripitaka Koreana in Haein Temple, Hapcheon Province is the most historical and largest heritage in this country, however the species of their blocks have yet been unknown. A nondestructive test method is necessary to investigate their species. The oven-dry density of wood was measured by inversely using the principle of high frequency moisture meter. The oven-dry densities of more than 100 domestic species of specimens estimated by measurement method and high frequency moisture meter were compared and following conclusions were obtained. There was highly close correlation between the oven-dry density estimated by measurement method and the oven-dry density estimated by high frequency moisture meter. The densities of Tripitaka Koreana that was a global cultural heritage could be correctly estimated by using high frequency moisture meter and the equilibrium moisture content under which Tripitaka Koreana equilibrated, thus, it was expected to provide the key to species identification.

Small cherry specimens modified with acetic anhydride and formaldehyde vapor phase were weathered by outdoor exposure and accelerated conditioning in a climate chamber. The effects of the chemical modification were evaluated by measuring their weight percentage gains (WPG), hygroscopicity and color differences before and after weathering. The average WPGs of the 72 hour acetylated and formaldehyde-treated specimens were 8.1 and 15.7%, respectively. After outdoor exposure for more than 2 months, the acetylated specimens lost weights by only 1.5%, but the formaldehyde-treated did much more than the formers. It was revealed that acetylation reduced the hygroscopicity and discoloration of wood while formaldehyde treatment didn't. Moreover the longer is the formaldehyde treatment time the more degraded after weathering. It was concluded that the vapor-phase acetylation could be applied for improving the dimensional stability of old wooden blocks.
