There is provided a sensor node management method in which a user is unconscious of a service break even when a sensor mode has failed among a plurality of sensor nodes assuming intermittent operation. Specifically, a wind power generation system is provided with a wind turbine, the wind turbine including a blade that rotates in response to the wind, a generator that rotates with rotation of the blade to generate power, and an auxiliary machine that controls a pitch angle of the blade. At least one of the hydrotreating catalysts can contain aluminium phosphate. A selected button display control unit displays the desired button on the screen in a display mode different from the buttons not selected. On the other hand, if the oil becomes contaminated, the countdown rate is adjusted in a negative direction. In particular, the present invention is directed to histidine kinases from Neurospora, Candida, and Aspergillus, and related compositions.
