Abstract: A computer-implemented method of managing the productivity of fish in a land-based aquafarm through data prediction for each growth period is proposed. The method may include predicting, at a processor, a feed amount input to an aquaculture tank based on aquaculture tank sensing data. The method may also include predicting, at the processor, the growth of fish based on results of the prediction of the input feed amount.

Abstract: A photoelectric conversion device includes a first photoelectric conversion unit on a substrate and having a first energy bandgap, a second photoelectric conversion unit having a second energy bandgap that is different from the first energy bandgap, the second photoelectric conversion unit being on the first photoelectric conversion unit, and an intermediate unit between the first and second photoelectric conversion units, the intermediate unit including a stack of a first intermediate layer and a second intermediate layer, each of the first intermediate layer and the second intermediate layer having a refractive index that is smaller than that of the first photoelectric conversion unit, the first intermediate layer having a first refractive index, and the second intermediate layer having a second refractive index that is smaller than the first refractive index.

Abstract: An optical sheet includes a substrate onto which light is incident, and a convex part protruded from the substrate by a predetermined thickness. A thickness of the convex part increases from an edge to a center thereof.
