  • Publication number: 20090131558
    Abstract: Disclosed is a modified asphalt composition obtained by blending asphalt with a complex block copolymer, which is prepared by polymerizing styrene in the presence of an anionic polymerization initiator to prepare a polystyrene solution, adding butadiene to the polystyrene solution, and then further polymerizing styrene, and wherein a triblock copolymer and diblock copolymer are present at a specific proportion. The modified asphalt composition of the present invention exhibits superior ductility at low temperature, while exhibiting comparable or better softening point as compared to conventional compositions, and, thus, is applicable to road paving, waterproof sheets and sealants.

  • Publication number: 20040015719
    Abstract: A firewall interconnects and controls access between external and internal networks, and a plurality of security agents monitor a data flow and system calls over the internal network. An intelligent security engine (ISE) is for analyzing an alert message, a traffic information and an event information transferred from the plurality of security agents to decide if there is an attack and to generate a signature through a learning process. A security policy manager (SPM) is for managing and applying a security policy to each of the plurality of security agents based on the decision of the ISE. The ISE performs a correlation analysis and a causation analysis on suspicious traffic and events and a detection message transferred from the plurality of security agents. Further, the ISE carries out a pattern analysis and generates a new detection pattern through a self-learning process.

  • Publication number: 20030233333
    Abstract: A remittance intermediating service system includes a service provider server which receives a remittance request including a remitter's account information, a recipient's account information and a remittance amount. A client browser, equipped with screen scraping modules, receives a first remittance request and a remitter's certification information from the service provider server, accesses a computer system of a first bank containing the remitter's account, remits the remittance amount from the remitter's account to a first mother account of the service provider contained in the same bank, and sends a remittance result to the service provider server. A plurality of screen scraping terminals receive a second remittance request from the service provider server, remit the remittance amount from a second mother account of the service provider contained in a second bank to a recipient's account contained in the second bank, and send a remittance result to the service provider server.
