Patent number: 7464337Abstract: 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.Type: GrantFiled: February 26, 2001Date of Patent: December 9, 2008Assignee: Inha University FoundationInventors: Kyungsook Han, Sangrae Lee

Patent number: 7280921Abstract: 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.Type: GrantFiled: November 7, 2002Date of Patent: October 9, 2007Assignee: Inha University Foundation, Inha UniversityInventors: Kyungsook Han, Byong-Hyon Ju

Patent number: 6651010Abstract: 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.Type: GrantFiled: December 11, 1998Date of Patent: November 18, 2003Assignee: INHA University FoundationInventors: Kyungsook Han, Dohyung Kim, Hong-Jin Kim

Patent number: 6291726Abstract: The nitration of aromatic compounds is achieved in high yield and selectivity by using oxygen activated by an inorganic catalyst and nitrogen dioxide. Since this process uses neither concentration nitric nor sulfuric acids, the generation of spent waste acid does not occur. Furthermore, the process does not encounter the problem of high costs associated with the generation of ozone as in an alternative nitration process. Since the solubility of oxygen in a reaction medium is increased by using pressurized oxygen, nitrogen dioxide is activated by a porous inorganic oxide and thus an aromatic compound(e.g., benzene) is nitrated into a nitro compound (e.g., PhNO2), the reaction rate is significantly increased, and the recovery of reactants is easy due to the insolubility of the catalyst.Type: GrantFiled: October 18, 2000Date of Patent: September 18, 2001Assignee: Inha University FoundationInventors: Bon-Su Lee, Kyoo-Hyun Chung, Yoon-Sik Lee, Young-Gyu Kim
