Abstract: Disclosed are a method for generating an electrocardiogram for personal identification and a method for identifying a person using the electrocardiogram. The electrocardiogram generation method generates a normalized electrocardiogram by extracting single-cycle electrocardiogram signals meaningful for personal identification from an electrocardiogram of a person and by connecting the extracted single-cycle electrocardiogram signals arranged in temporal order. Therefore, the electrocardiogram generation method dramatically increases identification accuracy in personal identification.

Abstract: A metal/support catalyst for conversion of carbon dioxide to methane contains a metal including a transition metal and a support containing a perovskite-type oxide, on which the metal is supported. The metal/support catalyst for conversion of carbon dioxide to methane is capable of increasing the catalytic activity of the Sabatier reaction by promoting the formation of hydroxide ions and helping the production of formate, which is a reaction intermediate in the conversion of carbon dioxide to methane, without using a precious metal. In addition, it is capable of conducting the reaction stably for a long period of time.

Abstract: A CD video-song accompaniment apparatus reproduces information from a compact disc and contains a CD reproducing portion, a CD-OK reproducing portion, and audio selector, and a main controller. The CD reproducing portion reads audio data from the compact disc and generates an audio signal if the compact disc is a first type of compact disc. On the other hand, the CD reproducing portion reads digital data from the compact disc if the compact disc is a second type of compact disc. The CD-OK reproducing portion inputs the digital data, which contains background image data and music information data, generates a first background image and a second background image based on the background image data, and generates a CD-OK audio signal based on the music information data. The audio selector inputs the audio signal generated by the CD reproducing portion and the CD-OK audio signal generated by the CD-OK reproducing portion and selectively outputs either the audio signal or the CD-OK audio signal.
