Abstract: A passive auxiliary condensing apparatus of a nuclear power plant includes a steam generation unit configured to heat a water supplied thereto into a steam by a heat produced when operating a nuclear reactor, a water cooled heat exchange unit connected to the steam generation unit and configured to store a cooling water therein to condense the steam provided from the steam generation unit, and a steam-water separation tank including a first side connected to the water cooled heat exchange unit and a second side connected to the steam generation unit, wherein a mixture of a water and a steam provided from the water cooled heat exchange unit is separated into the water and the steam to provide only the water to the steam generation unit.

Abstract: Provided is a method of refreshing a memory device by controlling a self-refresh cycle according to temperature. In the method, first self-refresh and second self-refresh are performed according to inner temperature of the memory device and a self-refresh cycle is controlled such that an all-bank-refresh (ABR) operation is not performed simultaneously with the start of the second self-refresh. The ABR operation is performed at the start of third self-refresh when the sum of a section of the first self-refresh in which the ABR operation is not performed and a section of the second self-refresh in which the ABR operation is not performed corresponds to a self-refresh cycle.

Abstract: Disclosed are a mobile communication terminal including two lamps and a method for providing GPS services using the terminal, so as to promote users' convenience while providing various kinds of services. The device and method aim to support increasingly-diversified services of mobile communication terminals and particularly to allow the two lamps to be applied in providing services such as a GPS service which need to provide information indicating two navigation directions. Two lamps for incoming call notification are mounted on the external of the terminal. Each of the lamps is composed of a light emitting element. A display controller is provided inside the terminal for controlling the two lamps.
