The biodeterioration behaviors of square post to support the wooden printing blocks Shelves in the Janggeongpanjeon were investigated according to the positions and parts of square post, and environmental conditions. It was found that a high differences of deterioration in the progressing levels of wood decay, according to the positions and parts of square post, and environmental conditions. The decay levels were very high and still progressing in the contacted areas with stone foundation which are about up to 50 cm above it. In the decay type, white rot fungi was mainly affected in the inside of building which mainly made of softwood. The decay in the square posts to support the wooden printing block shelves inside of building was worse in the rear side, compared to front side. The insects was not found in most of square posts excluding the post which was neighboring at the infected round column by insect.

The biodeterioration behaviors of wooden parts in the Janggeongpanjeon built in 15 century were investigated according to the types of wood species, positions and parts of wooden column, and environmental conditions. It was found that a high differences of deterioration in the progressing levels of wood decay, according to the types of wood species, positions and parts of wooden column, and environmental conditions. The decay levels were high in the contacted areas with stone foundation which are about up to 8~40 cm above it, although it was shown the many of wooden parts of the round columns are still good condition. In the case of decay type, it was shown the brown-rot in many of the columns at outside of building which made of hardwoods. The decay in position of the columns was most serious in the directions of east-north, west-north and north. It was also indicated that the durability of Zelkova serrata was higher than other wood species of the round columns, while it was in inferior anti-insects.
