    Abstract: The present disclosure relates to a method for immobilizing heparin and a NO-generating catalyst and a cardiovascular device having a surface modified using the same, and more particularly, to a method of co-immobilizing a heparin-phenol derivative and copper nanoparticles as a NO-generating catalyst on the surface of a material by a polyphenol oxidase-mediated reaction, a material having a surface with heparin and a NO-generating catalyst co-immobilized thereon by using the method, and a cardiovascular device including the material. It has been confirmed that a surface having heparin and the NO-generating catalyst co-immobilized thereon by the method of the present disclosure has high in vivo stability, continuously generates NO, and also promotes the proliferation of endothelial cells while significantly inhibiting the adhesion and activation of platelets and smooth muscle cells. Thus, the method may be advantageously applied to cardiovascular devices for inhibiting thrombosis and restenosis.

    Abstract: A laryngeal mask airway includes: a guide tube that has one proximal end portion inserted into the larynx inside the trachea and the other distal end portion exposed to the outside of the trachea, guides the insertion of a flexible bronchoscope and an endotracheal tube inserted into the trachea, and is divided into left and right sides; a mask that is integrally connected to the one proximal end portion of the guide tube, prevents fluid and air from flowing into the larynx inside the trachea from the outside, and is divided into the left and right sides; a handle portion that is provided on the other side of the guide tube and protrudes to both sides of the guide tube to correspond to each other; and a coupling member that couples the guide tube and mask, which are divided into the left and right sides, to each other.

    Abstract: The present disclosure a method of decoding a polar code based on a shared node, the method includes extracting an input node from target data that are data to be decoded, by an extractor, sorting the input node as one of a first node of which the pattern of the frozen bit satisfies a predetermined first reference, a second node of which the pattern of the information bit satisfies a predetermined second reference, and a third node that is not the first node and the second node, by a sorter, calculating at least one codeword candidate and at least one path metric that correspond to the input node in accordance with the sorting result by a calculator, finishing decoding the target data by iterating the extracting, the sorting as one, and the calculating of at least one path metric by a controller.
