Abstract: The present invention discloses a method for analyzing a HCV genotype by extracting RNA from plasma and serum, performing C-type hepatitis virus (HCV) RT-PCR and then making them react on an oligonucleotide chip. The present invention also provides a method for simply and exactly examining the analysis of the HCV genotype for four people on one slide.

Abstract: The present invention relates to a catalyst for homo-polymerization or co-polymerization of ethylene, or more particularly to a solid complex titanium catalyst for homo-polymerization or co-polymerization of ethylene. The catalyst may be produced by preparing a magnesium solution by contact-reacting a magnesium halide compound with an alcohol. Reacting the solution with an ester compound and a boron compound. Then reacting the solution with a mixture of a titanium compound and a silicon compound.

Abstract: A method for preparing pyrazolopyrimidinone derivatives and their pharmaceutically acceptable salts having efficacy on the treatment of impotence, one of male sexual dysfunctions. The method comprises the steps of: a) chlorosulfonating a pyrazolamide compound to obtain a chlorosulfonated compound; b) reacting the chlorosulfonated compound of step (a) with a primary amine to obtain a sulfonamide compound and c) performing an intramolecular cyclization of the sulfonamide compound of step (b) to produce the compound of formula below 1, wherein the steps b) and c) are performed in situ in alcohol by adding a base to the reaction mixture without workup after the step b) is completed.

Abstract: An optical fiber array block includes at least one optical waveguide having an optical fiber zone, and an optical device. An optical signal leakage window is formed at the optical waveguide, and the optical device corresponds to the optical signal leakage window. If the optical signal leakage window is formed at an optical fiber comprising a core and a clad layer, the clad layer is partially removed or is partially connected to the core by means of tan ion implantation technique. Thus, the clad layer has a refractive index that is similar to that of the core.
