The goal of this thesis is to make a comparative study about the variant form of the Chinese character in the five sorts of old maps drawing outside of the main gates of old map including DeDongYei-jido. The main task of this thesis can be classified under three heads - (1) introducing the literature of comparative study in the five sorts of old maps including DeDongYei-jido (2) classification of variant form in the five sorts of old maps (3) characteristic of variant form in the five sorts of old maps. In this thesis, aspect of variant form is classified under six head - (1) variation of the whole shape of the character (2) taking place the variation in both sides of Chinese character (3) taking place the variation in part (4) taking place variation in the strokes of the Chinese character (5) misusing different characters (6) changing different characters. This thesis explains some characteristic of variant form - (1) simplification of the shape of characters (2) using the Hou-qi-zi(後起字, Chinese character which is actually the same but made the next) (3) replacing the overlapped both sides of Chinese character with omit mark (4) a wrongly written character (5) discovering the variant form such as variant form of 廣, 广 variant form of 廛, variant form of 院 which was not recorded in Chinese literature. From now on, there should be some collections of variant form of Korean style and study. we are going to have to standardize aspect of variation and rule of variant form in old maps until we have to make some ways to recognize the block letter.

This study was carried out to characterize virus-like particles (VLPs) in Pleurotus ostreatus. The white and the dark gray mutants frequently observed in mushroom farms of Pleurotus ostreatus (Wonhyeong-neutari). A 5.8kb segments of dsRNA was detected only in the white mutants but not in the dark gray mutants. The VLPs were purified from the fruit bodies by Polyethylene Glycol (PEG) and ultracentrifugation. Electron microscopy analysis showed that VLPs were isometric about 14, 20~45nm in diameter. Further study is needed to reveal the morphological and yield variations of mushroom strains including VLPs observed in the mushroom farms. Also it is needed to maintain fundamental research for taxonomy, diagnosis, and physiology of VLPs in the mushroom strains.
