A signal processing method and apparatus for measuring heartbeat and oxygen saturation. The signal processing apparatus may acquire a first sampled signal by sampling a detection signal output from an optical detector in an interval in which a light source is activated, may acquire a second sampled signal by sampling a detection signal output from the optical detector in an interval in which the light source is inactivated, and may output a combined signal in which the first sampled signal and the second sampled signal are combined. An amplitude of the first sampled signal may decrease by combining the first sampled signal with the second sampled signal.

The present invention relates to a method for improving a repebody protein comprising repeat modules and a nucleotide library encoding a repebody protein library for improving the repebody protein. More particularly, the present invention relates to a method for improving a repebody protein using a module evolution method of sequentially mutating repeat modules constituting the repebody protein, and a nucleotide library encoding a repebody protein library used to improve the protein. According to the module evolution method of the present invention, an improved repebody protein can be screened which has a high binding affinity and accordingly increased specificity and activity, and thus it is easy to express a repebody used as an inhibitor, a therapeutic agent, and an analysis means against a target substance.

Disclosed is a method and related system of regenerating a raw material for a hydrogen supply system of a fuel cell. The method includes reacting aluminum and a metal hydroxide to produce hydrogen in the hydrogen supply system of a fuel cell; and recovering an aluminum compound produced simultaneously with the hydrogen in the reaction. An aluminum hydroxide is obtained from the aluminum compound. The aluminum hydroxide is heat-treated to obtain an aluminum oxide. The aluminum oxide is reduced to obtain aluminum. The obtained aluminum is re-supplied as a raw material for producing the hydrogen.
