Abstract: Provided is an information processing apparatus including an acquiring unit that acquires cell information indicating a state of a cell from production of a pluripotent stem cell to differentiation of the pluripotent stem cell into a specific differentiated cell by differentiation induction, and process history information indicating a history of a processing process for obtaining the differentiated cell, and a deriving unit that derives differentiation potency information indicating differentiation potency of the pluripotent stem cell based on the cell information and the process history information which are acquired by the acquiring unit.

Abstract: A protection cover for an eaves gutter capable of permitting snow lumps, fallen leaves, pebbles, sand, dust and the like dropping from an eaves edge of a roof to smoothly slip off the protection cover to drop onto the ground under the eaves and thus preventing them from entering the eaves gutter. The protection cover includes a net cover body fitted on an upper opening of the eaves gutter. The net cover body is formed so as to have a central portion upwardly arcuately expanded and both lateral portions laterally arcuately expanded while being downwardly inclined from the central portion. The protection cover also includes a pair of fixing frames for tightly fixing opposite lateral edges of the net cover body to respective lateral upper edges of the eaves gutter.
