Abstract: The present invention relates to a composition for preventing or treating ischemia-reperfusion injury, the composition comprising an NADPH oxidase 1 (NOX1) inhibitor as an active ingredient, and more specifically, to a composition exhibiting prophylactic or therapeutic effects on ischemia reperfusion injury by suppressing the signaling of extracellular-signal-regulated kinase (ERK) by means of reactive oxygen species (ROS).

Abstract: The present invention relates to a mixed ink mixed with a far-infrared-emitting material, a method for preparing the mixed ink, and a printed matter on which the mixed ink is printed, wherein the mixed ink is a printing ink used in a printing process for a printed matter and the mixed ink is prepared by mixing a pigment mixture with a powder type far-infrared-emitting material. Therefore, a mixed ink, which is to be printed on an object, is mixed with a far-infrared-emitting material to maintain a high far-infrared emissivity of 0.88 or greater, so that 60% or more of various noxious gases, which are generated from the printed matter, can be deodorized to allow a user to use the printed matter without repulsion; about 90% or more of staphylococci and pneumococci can be reduced to maintain cleanliness; and the contamination and pathogen transmission due to the use of the printed matter can be prevented in advance.

Abstract: Disclosed herein are an authentication and payment system and method. The authentication and payment system of the present invention includes an issuer server, an issuer information management intermediate server, an acquirer server and a payment server. The issuer server issues, manages and operates payment means. The issuer information management intermediate server manages URL information required to access domestic and foreign issuer servers. The acquirer server performs payment approval and performs acquisition and settlement for member stores. The payment server intermediates between the issuer server and the acquirer server to provide an authentication and payment service in response to a request from a terminal of the merchant. Accordingly, the present invention can provide a safe and convenient payment process with respect to payment means, such as credit cards, electronic money or mobile phone micro payment that can be selected between a purchaser and a merchant.

Abstract: A local wireless signal receiving apparatus using digital RF processing technology including: a receiving digital RF processor receiving an RF signal and detecting an IF signal from the received RF signal; a zero-crossing signal detector detecting a zero-crossing signal from the detected IF signal, and converting the detected zero-crossing signal into a digital signal; and a receiving signal processor converting the digital signal into a local wireless signal.

Abstract: The present invention relates to a system and to a method for QoS (Quality of Service) support in a ubiquitous sensor network. The system for QoS support in a ubiquitous sensor network includes a mesh coordinator and nodes. The mesh coordinator organizes a super frame containing a dedicated QoS data transmission period, and synchronizes each of the nodes constituted into one network with the abovementioned super frame. The nodes create a beacon frame containing information on whether or not to set QoS, to broadcast the beacon frame in a dedicated beacon period of the super frame if QoS data transmission is needed, to create a QoS data frame with a set priority, and to transmit the QoS data frame to the dedicated QoS data transmission period of the super frame in the case of transmitting QoS data.

Abstract: A local wireless signal transmitting/receiving apparatus and method using digital RF processing technology. When the local wireless signal transmitting/receiving apparatus generates a local wireless signal to be transmitted, spreads the frequency of the generated local wireless signal and thereby generates a baseband signal, the local wireless signal transmitting/receiving apparatus converts the baseband signal of the local wireless signal into phase information, converts the phase information into an RF signal by means of a polar modulator, and transmits the RF signal.
