Abstract: A dual mode twisted string actuator using a clutch is provided. The twisted string actuator according to an exemplary embodiment of the present disclosure includes: a first actuator; a first coupler which is rotated by the first actuator; a shaft which is coupled to and interlocked with the first coupler; a second coupler which is selectively interlocked with the first coupler and comprises a plurality of string receiving portions; and a string which has one end fixed to the first coupler and the other end fixed to a moving body through the string receiving portions of the second coupler. Accordingly, it is possible to reduce the size of the existing large and heavy transmission system and to miniaturize and lighten the size of the entire drive system.

Abstract: A method for setting a beam in a mobile communication system includes determining at least one of a beam width and a beam direction in consideration of a criteria value in response to a failure of a random access attempt, and retransmitting a beam based on the determined at least one of the beam width or the beam direction. The criteria value includes at least one of a beam gain history of a candidate beam combination and a previous transmission failure history.

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.
