Abstract: A power generation structure according to an embodiment of the present invention comprises: terrain features spaced apart from each other at a first interval to thereby form a watercourse through which water can move in the front and rear directions; watercourse banks having a width narrower than the first interval and disposed on the watercourse to thereby respectively form equal-width watercourses having a constant width between the terrain features; a first water collecting bank disposed on the watercourse and formed in the shape of a tip extending from the front end of the watercourse bank on the basis of the moving direction of a tidal current, with the width being gradually decreased toward the front of the equal-width watercourse; and a second water collecting bank disposed on the watercourse and formed in the shape of a tip extending from the rear end of the watercourse bank on the basis of the moving direction of the tidal current, with the width being gradually decreased toward the rear of the equal

Abstract: A method for providing information to dispersed users based on an integrative cache on a communication network is provided. The method includes collecting information on the communication network, integrating the collected information and storing the collected information as a cache in a database, receiving an information request from the terminal device of the dispersed users, and determining in a symmetrical area of the communication network if the requested information exists as a cache in the database to control the path of the requested information.
