  • Publication number: 20040161790
    Abstract: Provided are an apparatus and a method for coding genetic information. An aligning unit aligns sample genetic information, wild-type probe genetic information, and mutant-type probe genetic information, based on a mutation position. A code storage unit stores first orthogonal codes assigned to each of bases located at left and right base regions based on the mutation position and second orthogonal codes assigned to a base located at the mutation position. A coding unit creates first code strings and second code strings.

  • Publication number: 20040158408
    Abstract: A server-client network system for genotyping analysis and a computer readable medium used therein are provided. The server-client network system includes a server storing databases required for genotyping analysis and providing the databases to a client and the client receiving the results of a test on the target sample using a biochip and performing a genotyping analysis on the target sample with reference to the databases provided from the server. The server-client network system improves the security of privacy information and guarantees the independency of analysis software.

  • Patent number: 5808619
    Abstract: A real-time rendering method for selectively performing bump mapping and Phong shading processes and a rendering apparatus therefor are provided. The rendering method includes the step of calculating a ambient factor, the step of bump-mapping a diffuse factor and selectively outputting the bump-mapped diffuse factor or the diffuse factor prior to the bump mapping according to a bump mapping/Phong shading selection signal, the step of bump-mapping a specular factor and selectively outputting the bump-mapped specular factor or the specular factor prior to the bump mapping according to the bump mapping/Phong shading selection signal and the step of summing the ambient factor, the selectively output diffuse factor and the selectively output specular factor and obtaining the value of intensity. Therefore, bump mapping and Phong shading processes are selectively performed. Also, there is no discontinuity at the borders of each polygon.
