Abstract: The present invention is directed to a method of calculating the results of a moving k-nearest query and safe exit locations in a road network, and more particularly to a method and apparatus that receive a request from a client terminal and provide the results of a k-nearest query, a safe zone and safe exit locations together. In the present invention, a query is processed in a server, a request for a query from a querying user and the location information of the querying user are received from an LBS, the location information of the querying user is anonymized and then the query request is transferred to the server, and query results corresponding to the anonymized location information of the querying user are received from the server and then transferred to the querying user, thereby protecting the location information of the querying user.

Abstract: The present invention relates to an apparatus and a method for managing a buffer having three states on the basis of a flash memory and, more specifically, to an apparatus and a method for improving the performance of a database management system (DBMS) on the basis of the flash memory and a use life span of a storage device by reducing a writing operation for a flash memory device in which the writing operation is very slow in comparison with a reading operation, through an efficient buffer managing method and a new index node split policy. To this end, the buffer management device having three states on the basis of the flash memory according to an embodiment of the present invention comprises: a buffer memory unit; a list management unit; a buffer memory management unit; and a log buffer unit.

Abstract: The present invention relates to a method of computing the result of a moving range query and the locations of safe exits in a road network and, more particularly, to a method and apparatus that receive a range query request from a moving client terminal and that provide a range query result, a safe region in which the range query result is maintained, and the locations of safe exits. The present invention provides a method in which a server provides a first query processing result and information about a safe region that provides a range query result identical to the first query result, thereby minimizing communication between a server and a client terminal when the client terminal is located in the safe region.
