    Abstract: An apparatus and method for compensating for duty signals are disclosed herein. The apparatus for compensating for duty signals includes a signal input unit, a signal control unit, a combined signal control unit, a determination unit, and a signal output unit. The signal input unit receives a first signal and a second signal. The signal control unit controls the timing of the first and second signals based on first and second control signals, and outputs a combined signal. The combined signal control unit outputs first and second logic operation signals. The determination unit generates the first and second control signals if the timing of the first signal does not match the timing of the second signal, outputs the generated first and second control signals, and applies a third control signal to the combined signal control unit. The signal output unit outputs the first and second signals.

  • Patent number: 9181542
    Abstract: The present invention relates to a method for increasing chaperone activity by irradiating peroxiredoxin (Prx) proteins. More particularly, the present invention may be useful for preparing recombinant proteins imparting resistance against various environmental stresses by increasing the chaperone activity of peroxiredoxin, since it has been observed that irradiated peroxiredoxin has enhanced chaperone activity characteristics, wherein an ?-helix structure decreases while a ?-sheet structure increases, from analysis results of a protein structure change and chaperone activity after irradiating two types of peroxiredoxins (2-Cys, 3-Cys) which are two active cysteine motifs of peroxiredoxin.
