Abstract: Disclosed are an apparatus, a method, and a computer program by which it is determined whether a target network program generated in a software defined network is malicious by extracting a feature of a behavior graph of the target network program and applying machine learning to the behavior graph. Accordingly, a security and safety of a software defined network may be improved by detecting whether a computer program is malicious before the malware is installed.

Abstract: A method for preparing acrylic acid, more specifically, to a method for preparing acrylic acid under a neutral condition at high yield in a short time without using a base, unlike the prior art in which a base is essentially used. The acrylic acid is produced using a supported catalyst having a specific composition when preparing acrylic acid by oxidation of allyl alcohol. Particularly, the preparation method can recover acrylic acid rather than acrylic acid salt as a final product, and thus has an advantage that the overall process cost can be reduced by eliminating essential processes in the prior art, such as ion exchange after the acidification process required for the conversion of acrylic acid salt to acrylic acid.

Abstract: The present invention relates to a method of detecting and quantifying biomolecules using nucleic acid polymerase activity controlled by the target molecule, and more particularly to a method for detecting or quantifying biomolecules, which can detect and quantify nucleic acids, proteins, small-molecular substances, physiologically active substances (enzymatic activities), etc., with high sensitivity, based on the change in DNA polymerase activity caused by specific binding of a specific nucleic acid that forms a complex with a DNA aptamer prepared so as to comprise a single-stranded DNA that specifically recognizes the specific nucleic acid. The present invention can provide a method for diagnosing biomolecules, which can detect and quantify target nucleic acids, target proteins, target small-molecular substances, target enzyme activities and the like in a label-free and sensitive manner by controlling polymerase activity through target molecule-induced conformational change of a DNA aptamer.
