Sunbi was the groups of men who studied Confucian Classics in school and practiced it in society, especially in " Ru-Jeong", and their main subjects in study were the place of man in the universe and the roles of man in the world, and the real nature of man. they thought that the the meaning of man was in the human relations at the "Ru-Jeong". “Ru-Jeong"had been functioned as an important outdoor space in our traditional lives, searching for some meanings within the history of Korean education. The purpose of this study is to review meaning of eduaction had relation 'Sunbi-Thought' to " Ru-jeong" in dynasty Chosen. As a result, “Ru-jeong" had been functioned as a place of process growth of Sun-bi and as a meaningful performing space for thought of sunbi.

This study considered the internal flow considering the internal shape of the CNG filling nozzle, which is widely distributed in Korea. The CNG filling nozzle is the last part to pass through in the CNG filling process and has a significant influence on the filling efficiency. The mechanism was identified by disassembling the CNG filling nozzle and performing a flow analysis according to the mechanism. Consequently, the energy loss owing to eddy currents in the flow was determined, and modeling was proposed to reduce the energy loss by simplifying the shape and parts.
