Abstract: A mobile terminal and a method of managing meeting information using the same are provided. The method of managing meeting information using a first mobile terminal includes acquiring meeting information including identification data of at least one location data sharing mobile terminal existing within a meeting distance from the present location of the first mobile terminal in response to a request to acquire meeting information, and displaying the meeting information in response to a request to search the meeting information.

Abstract: Provided are a method of providing a service relating to content stored in a portable storage device to an external device, and an apparatus therefor. The method includes outputting a user interface to manage information relating to contents stored in the portable storage device through a display unit associated with the external device, receiving a command to select content from among the contents through the output user interface, executing a service corresponding to the content selected based on the command, and providing a result of executing the service to the external device.

Abstract: Example embodiments provide a method of de-chucking a wafer by alternating between using a direct voltage and an alternating voltage, and an apparatus for fabricating a semiconductor device using the same. The method of de-chucking a wafer comprises interrupting a chucking voltage applied to an electrostatic chuck, applying a first de-chucking voltage to the electrostatic chuck, and applying a second de-chucking voltage to the electrostatic chuck.

Abstract: An input/output control method and apparatus optimized for a flash memory, which can improve the performance of the flash memory. The input/output control method optimized for a flash memory includes determining whether a random write operation of data occurs in a flash memory, and successively writing randomly input data in a predetermined surplus region of the flash memory if it is judged that the random write operation occurs.
