This study was investigated the potential of ducks and fish trap for the control of golden apple snail, Pomacea canaliculata, in paddy field and water canals. The smaller size of duck (700g) preyed snails than the bigger one (1,300g). The consumption of two ducks was bigger under plastic house. They preyed over 90% on the second days of release. The release time of ducks was more effective at seven days after inoculation of snails than simultaneous. Duck could suppress the density of snails at any time from month after inoculation. Four ducks per $30m^2$ could control snails in an irrigation canals. The number of attracted golden apple snail per week was 216 in big fish trap $({\Phi}15cm)$ with menthol paste which for a carp.

This study includes the taxonomy , and a key to species of aphids in the family Lachnidae from Korea. Specimens examined in this study were collected from 24 kinds of plants. Samplings were accomplished at 95 localities in Korea from March, 1987 to August, 1994. A list of Korean lachnids are as follows. *1. Chinara atlantica (Wilson, 1919), *.2. C. cembrae(Seitner, 1936), *3. C. formosana (Takahashi, 1924), *4. C. fresai Blanchard, 1939, *5. C. idahoensis Knowlton,1935, 6. c. juniperi (de Geer, 1773), 7.C.kochi Inouye,1939, *8.

Of them , 27 species preceded by an asterisk were observed in this study, and keys to these 27 Korean lachnids are provided . The relationship between Korean lachnids and their host plants, and geogrpahical distribution are discussed.

Pomacea canaliculate (channeled apple snail; CAS), which is one of the world's worst alien invasive species, is widely distributed in Korea, and raised ecological and economic problems. In this study, we surveyed the distribution and dispersal characteristics of CAS in Korea, and analyzed the effects of environmental and anthropogenic (or social) factors on their distribution and dispersal. We considered various events related to CAS such as changes of policy including promotion of agriculture using CAS and enactment of biological diversity conservation law. Our results showed that human activities strongly influenced to the distribution and dispersal of CAS in Korea. Distribution of CAS seemed to relate with environment-friendly agriculture considering environmental conditions of CAS habitats. And dispersal characteristics of CAS were significantly correlated with social factors such as cultivation area and rate of organic products, production CAS on inland fishery.

This study produced the serious game based of Sacheonwang for the smart phone. The popularization of smart phone has expanded the contents market. However the game content made of various Korean traditional cultures is just few. According to this problem, it considered Sacheonwang (Dongbang Jigukcheonwang, Bukbang Damuncheonwang, Namban jungcheonwang, Seobang Gwangmokchoenwang) and tried to develop the serious game application of smart phone based on the Korean traditional culture. It modernized the 4 types of Sacheonwang analyzed the characteristics, and it was created to super deformed characters. It suggested the production and development of game using Sacheonwang character and the Buddhist image. This study looked at the contents of the Buddhist and developed the Buddhist civilization and applied on the game contents to extend Korean traditional culture and interact Korean traditional culture. This study, therefore, will develop the Korean traditional characters and the game content using the research of the Buddhist cultural elements.

It is possible to cultivate Pleurotus ostreatus on the crush medium of Reynoutria sachalinensis. The crush of leaves and stems of Reynoutria sachalinensis with water (1:8 W/V) enhanced mycelial growth of P. ostreatus. That mycelial growth of P. ostreatus on the crush medium was accelerated three times as fast as that on malt extract agar (MEA), and mycelial compactness was denser than that of on MEA. The same result was obtained on mixture of saw dust and the crush of leaves and stems in test tube and bottle. The addition of rice bran and the crush to saw dust was best for mycelial growth. Regardless of pH (4.5, 6.5 and 8.5), P. ostreatus could suppress the growth.

Fools usually make people laugh through their comic appearances and foolish behaviors. A fool in King Lear also gives us pleasure by his unique jokes and humors, however, he is not so foolish. He is very wise and has the intuition to penetrate people's mind and understands the facts. He predicts the future, criticizes the untrueness and heals the wounded mind. He always keeps Lear company and makes him realize his own foolishness. After getting out of his own suffering and fear, Lear experiences his healing process of purification with the help of the fool. In this respect, the fool in King Lear is a wise helper and healer for King Lear.

It stand on the basis of a mind, intention, innate knowledge and things, same as Four-Sentence Teaching. Wangshouren's gongfu theory of "Daxue" changes from gewu to chengyi, from chengyi to zhizhi again. It is deepening of Wangshouren's philosophy and is the change of education. It is also that Wangshouren's gongfu theory internalize anything. He spent his younger life in pursuit of Zhuxi's gewu. Through a lecture of LongChang, Wangshouren's gongfu theory of "Daxue" changes from extroversion to introversion. According to Wangshouren' opinion, "Daxuewen" is the tenet of the XinXue, same as Four-Sentence Teaching. This papers mainly emphases two points: one, to analyze the thinking system of Wangshouren's "Daxuewen", make a comparative study of befour "Daxuewen" and after "Daxuewen". another, through this work we can understand thoroughly Wangshouren's viewpoint of "Daxue".
