Abstract: The present invention relates to a heteroaryl derivative compound and a use thereof. Since the heteroaryl derivative of the present invention exhibits excellent inhibitory activity against EGFR, the heteroaryl derivative can be usefully used as a therapeutic agent for EGFR-associated diseases.

Abstract: Provided are a method of controlling a resolution desired by a user in a graphics device of a digital data broadcasting receiver, an apparatus therefor, and a digital data broadcasting receiver using the same. The method includes providing a list of resolutions available on a graphic plane to a user; changing a resolution of the graphic plane according to a resolution selected by the user from the resolution list; and displaying an application on the graphic plane, the resolution of which has been changed.

Abstract: Provided are an apparatus and method for providing a preview of a menu object in a technique of displaying a menu object. The apparatus includes an input unit that receives an event from a user, an event processing unit that highlights objects, from among objects displayed on a screen, to which a user input can be applied according to the received event, and a display unit that displays the highlighted objects.

Abstract: An application program executing a method and an apparatus for improving the speed of executing an application program for a digital television (DTV) are provided. If log information exists for a resource used by an application program, the resource indicated by the log information is requested, and the application program is executed using the resource transmitted as per the request. Accordingly, it is possible to rapidly provide the application program with the resource used by the application program, thereby increasing the speed of executing the application program.

Abstract: A multimedia system that automatically scales an application according to the resolution of a graphics device when applications having different resolutions coexist on one screen, a method of scaling an application, and a recording medium storing a program for performing the method. The method includes setting a ratio of a reference resolution included in information regarding an application loaded to the multimedia system to a resolution of a graphics device of the multimedia system as a first scaling value; and scaling the application based on the first scaling value and displaying the application.

Abstract: A display apparatus and method that display directions in which objects navigatable from a currently activated object are located. The display apparatus includes a display unit, which displays an application program, an application program executing unit, which executes the application program so that the application program is displayed on a screen of the display unit, and a controlling unit, which determines whether there are objects navigatable from a currently activated object on the screen of the display unit and displays direction information on directions in which the objects navigatable from the currently activated object are located. Accordingly, directions in which the objects navigatable from the currently activated object are located are automatically displayed, thereby enabling a user to view the directions in which the objects navigatable from the currently activated object are located in advance.
