Abstract: The present invention relates to mutant DNA polymerases, their genes and their uses. More specifically, the present invention relates to mutant DNA polymerases which are originally isolated from Thermococcus sp NA1. strain and produced by site-specific mutagenesis, their amino acid sequences, genes encoding said mutant DNA polymerases, their nucleic acids and PCR methods by using thereof. As mutant DNA polymerases according to the present invention have decreased proofreading activity and changed function of inosine sensing effectively compared to wild type DNA polymerase, PCR using primers with specific nucleic acids has made rapid progress. Therefore, the present invention is broadly applicable for PCR in various molecular genetic technologies.

Abstract: To access control without changing a presently used version of a system application protocol, an operator enters an ID and a password of the operator for user authentication, and, if the user authentication is successful, the operator will have access to an application layer of a system managed using either TCP/IP or UDP/IP. The application layer is adapted to be accessed using a security module to confirm whether or not an IP address of a terminal used by the operator is a preset IP address. In a network operating a version of a network management interface not equipped with a security function, the security deficiency of the system is alleviated by simply adding the security module without effecting a version upgrade process.

Abstract: The present invention relates to a novel use of a biologically active protein, p53 as an inhibitor of hepatitis B virus(HBV) replication. The inhibitory role of p53 on HBV replication was assessed by the reduced levels of three different markers, i.e., HBsAg and HBc/eAg secreted into the medium, HBV DNA, and RNAs. Based on the above results, it was concluded that wild-type p53 specifically represses the activity of pregenomic/core promoter of HBV and inhibits the replication of HBV by down-regulation of the pregenomic/core promoter. Therefore, the present invention provides a novel use of protein p53 as a HBV replication inhibitor which can be developed into an agent for the treatment of acute/chronic hapatitis and prevention of liver cirrhosis and hepatocellular carcinoma(HCC) caused by HBV.
