Abstract: The present invention relates to a visualization method of RNA pseudoknot structures for more efficiently and clearly visualizing all types of RNA pseudoknot structures including H-types in the form of a planar graph without edge-crossing so that the structures can be easily examined. The visualization method comprises reading the structure data in bracket view, identifying stem-loops and pseudoknots enclosed in bracket pairs from the input structure data, first computing the position and shape of a stem-loop contained in an identified pseudoknot to visualize the stem-loop, second computing the position and shape of the pseudoknot containing the calculated stem-loop to visualize the pseudoknot, third computing the position and shape of a stem-loop outside the computed pseudoknot, and inserting or connecting the visualized stem-loops into or to the pseudoknots to complete an RNA pseudoknot structure drawing.

Abstract: A method for communication of multimedia data using virtual world interface in a mobile personal computers is disclosed. The method comprises logging in to the server; displaying an initial menu picture on a screen of the mobile personal computer, the initial menu picture including a plurality of menu items for transmission or retrieval of the multimedia data; and performing a subroutine associated with a selected one of the menu items in the initial menu picture to transmit or retrieve the multimedia data. According to this invention, information can rapidly and accurately be exchanged at any time or place. Further, desired media data can conveniently be transmitted or retrieved by merely a clicking operation of a stylus pen or a drag operation of a mouse without executing a multiplicity of individual programs for transmission and/or retrieval of different media data.

Abstract: Disclosed is a system for predicting programmed ribosomal frameshift sites in genome sequences, in which programmed frameshifts, which are difficult to detect because of their variation with gene types, are classified into ?1 frameshifts and +1 frameshifts as basic frameshift models, each consisting of four types of modules, and the modules are combined in various ways, whereby the system can predict frameshifts of various user-defined modules and computationally detect frameshifts at high efficiency. Also, the present invention provides related web service which is accessible regardless of the operating system of the user's computer. Request messages for frameshifts and response messages to the search results of frameshifts are sent and received in XML format, so that they can be flexibly applied to programs using various languages.

Abstract: Disclosed is a method of visualizing large-scale protein interaction data, comprising the steps of (1) producing an initial layout by placing all nodes of protein interaction data on the surface of a sphere by increasing horizontal and vertical angles of polar coordinates; and (2) yielding a graph by iterating a process moving each node of the initial layout to an equilibrium position considering global spring forces between non-adjacent nodes as well as local spring forces between adjacent nodes on a predetermined number of times, by which large-scale protein interaction data is effectively visualized in a three-dimensional space. The method for visualization of the present invention, which is much faster than the conventional algorithms, can be used for interactive analysis, as well as provide an integrated system capable of directly visualizing query results from a protein-protein interaction database.

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.

Abstract: Disclosed is a method for partitioned layout of protein interaction networks into a three-dimensional graph, comprising the steps of grouping nodes into group 1, group 2 and group 3 based on their interaction properties; computing shortest paths between nodes of each group, between nodes of the group 1 and nodes of the group 2, between nodes of the group 1 and nodes of the group 3, and between nodes of the group 2 and nodes of the group 3; and layout drawing by positioning nodes of the group 3 in the center of a sphere, nodes of the group 2 in the outer region of the group 3, and nodes of the group 1 in the outer region of the groups 2 and 3, by spring-force layout algorithm. The present invention is advantageous in terms of a clear and aesthetically pleasing drawing and being much faster than other forced-directed layouts.

Abstract: There is disclosed a method for visualizing secondary structures of RNA molecules, by which nearly overlap-free polygonal displays of RNA secondary structures are produced with minimal distortion to structural elements, with minimal search for positioning them, and with minimal user intervention. While vector and vector space are used to determine the direction and space of a structural element, two heuristics are adopted for the task of searching for the space and direction of structural elements. With the aid of the two heuristics, loops are positioned in decreasing order of their sizes and a helix is positioned, depending on the position of its adjacent loop which has been positioned. In consideration of both a potentially open and wide vector space and an allowed vector space, a structural element is positioned.
