Indonesian Lagocephalus wheeleri ("White-milbog") and Chinese Fugu obscurus ("Hwang-bong") puffers were dissected into liver, intestine, ovary or testis, skin and muscle for assay of toxicity, Also, the toxins from the puffer liver were partially purified and analyzed. The frequency of toxic specimens for Lagocephalus wheeleri was 20, 40, 0 and 10%, in terms of liver, intestine, skin and muscle, respectively; and average toxicity was 5.5$\pm$0.9(Mean$\pm$S.E.), 11.8$\pm$4.2, 2.2$\pm$0.1 and 3.0$\pm$0.8 MU/g, respectively. All of Fugu obscurus specimens had toxicity ranging between 2 and 210 MU/g. The frequency of toxicity in intestine and ovary, both 100% was to be higher percentage tan that of other tissues. The toxinsgave two spots tetrodotoxin(TTX) and anhydro-tetrodotoxin(anh-TTX) on TLC. Also, the toxin of each puffer species showed two spots in electrophoresis. In HPLC analysis of Fugu obscurus, the toxins showed TTX, 4-epi-TTX and anh-TTX.epi-TTX and anh-TTX.

This study aims at the consideration of the usages of traditional waterscape elements, which are difficult to define their concepts and their differences and it has been proceeded mainly with analysis of literature. It elicited various waterscape types by extracting the place names associated with the watersacpe elements from the chapter "Sancheon" of the volumes Gyeongsang-province in "Sinjeung Donggukyeojiseungram", which is a government-compiled geography book in the early period of Joseon Dynasty, and drew the features of each waterscape element by interpreting the dictionary definition and the original text and studying the similar examples. The results of study are drawn as follows. 1. The chapter "Sancheon" includes 22 types of waterscape elements and they are classified by means of locations and water-flow forms: River Landscape, Lake & Pond Landscape, Coast landscape. 2. River landscape maintaining constant natural water-flow constitutes the linear type, related to the class of stream, which includes 'Su(water)', 'Gang(river)', 'Cheon(stream)' and 'Gye(brook)' and the dotty type, created by the nature of trenched meander rivers, which includes 'Tan(beach)', 'Roe(rapids)', 'Pok(waterfall)' and 'Jeo(sandbank)'. 3. Lake & Pond Landscape forming water collected in a certain area constitutes 'Ho(lake)', which is a broad and calm spot created around mid and down stream of river, 'Yeon(pool)', 'Dam(pond)', 'Chu(small pond)', which are naturally created on the water path around mid and down stream of river, 'Ji(pond)', 'Dang(pond)', 'Taek(swamp)', which is collected on a flatland and 'Cheon(spring)', 'Jeong(spring)' which means gushing out naturally. 4. Coast Landscape includes 'Ryang', 'Hang', which are the space between land and an island or islands, 'Got(headland)' which sticks out from the coast into the sea, 'Jeong(sandbank)' which forms sandy beaches and 'Do' which shows high appearance frequency by reflecting the geographical importance of islands. This study comprehended the diversity of traditional waterscape elements and drew the fact that they are the concept reflecting the differentiated locational, scenic and functional features. That way, it understood the aesthetic sense on nature, which ancestors had formed with the interests in natural landscape and the keen observation on it, became the basic idea elucidating the characteristic on Korean traditional gardens, which minimize the artificiality and make nature the subject.
