Abstract: The accuracy of an intervention site in surgery is predicted and the predicted intervention site is presented to a surgeon. A surgery support apparatus includes a prediction data generation unit that generates prediction data predicting an intervention site based on data before an intervention using an artificial intelligence algorithm. The artificial intelligence algorithm is an artificial intelligence algorithm learning an intervention site by analyzing data before the intervention and intervention site data for an object, and outputs coordinates, a region, or a shape of one point of the intervention site as prediction data. Data before the intervention used for learning of the artificial intelligence algorithm and input data input to the artificial intelligence algorithm to generate prediction data correspond to image data, a segment image, a feature point, etc. The prediction data is displayed on a display apparatus together with an image of a patient acquired in advance.

Abstract: A solar power generation system includes a storage battery, a solar power generation device that is provided on the side of the storage battery and outputs solar generated power, and a power control device. The power control device includes a variation component extraction unit that extracts a shade variation component from a generated power signal measured by the solar power generation device, and a smoothing unit that smoothens the shade variation component obtained by the variation component extraction unit. The power control device obtains a charge/discharge target value of the storage battery on the basis of an output signal from the smoothing unit.
