Abstract: An apparatus and a method of changing a content display area on a screen of a portable device are provided. The method includes displaying a plurality of applications as a split view by respectively corresponding each of the plurality of applications to each of a plurality of split display areas of a display unit, and extending a display area of an application selected from the split view to be displayed as a main screen, and reducing a display area of an unselected application to be displayed as a sub screen.

Abstract: An apparatus and a method for processing a split view in a portable device. The method of processing a split view in a portable device, includes: displaying a plurality of applications as a split view corresponding to split display regions of a display unit; displaying an input panel on a display region of an application of the plurality of applications that did not call for the input panel when the input panel is called; and processing data input through the input panel by an application calling the input panel.

Abstract: Disclosed is a visualization method of RNA pseudoknot structures. The method of the invention comprises the steps of setting criteria required for visualizing RNA pseudoknots, setting structural elements and data structures for representing a whole RNA structure containing pseudoknots, determining an input format for visualization and a drawing order of the structure, determining connectivity relations between regular loops and stems in the structure and between pseudoknot loops and stems in the structure, calculating radii of the regular loop and the PK loop, calculating coordinates of bases in the regular loops, setting internal angles of the PK loops, calculating startAngles of the regular loops and angles of the stem, determining positions of the pseudoknots in the PK loops, and drawing the pseudoknots and the whole RNA structure containing the pseudoknots.
