Abstract: A combined power plant is provided. The combined power plant includes a gas turbine configured to combust fuel to generate a rotating force, a boiler configured to heat water to generate steam, an ammonia decomposition apparatus configured to receive a combustion gas generated in the gas turbine to thermally decompose ammonia to generate a decomposed gas containing hydrogen, nitrogen, and a residual ammonia, a steam turbine configured to generate a rotating force using the steam generated in the boiler, and a decomposed gas supply line configured to supply the decomposed gas generated in the ammonia decomposition apparatus to a combustor of the gas turbine.

Abstract: Provided is a terminal that displays the operability of an application including: a storage unit storing precondition information of the application relating to usage environment; a determination unit comparing the stored precondition information of the application and the current state information of the terminal, determining whether the application is normally operable; applying a visual effect based on the determination to an icon corresponding to the application; and displaying the visually affected icon. Accordingly, a user can intuitively check the status of the application desired to be executed, whereby the user convenience can be improved.

Abstract: A content sharing system using near field communication (NFC) in a cloud network, includes: a server to store contents; a first device having an authority to use the contents and generating first data including a list of shared contents among the contents and digital rights management (DRM) condition; and a second device to generate second data including a key value for identifying the second device and to transmit the second data to the first device when the NFC is activated for sharing the shared contents, wherein, in order to share the shared contents, the first device generates third data including the first data and second data. The contents may be encoded according to a device's performance criteria, and the sharing of the shared contents may be restricted according to location or distance.
