Abstract: A management apparatus includes circuitry to manage multiple structures including a fabrication object fabricated by a fabrication apparatus in a fabrication area of the fabrication apparatus and extract a combination of two or more structures from the multiple structures based on shape information of the multiple structures.

Abstract: An image forming device comprises: a receiving unit that receives a request from an external device; an acquiring unit that acquires a port number indicated by the request received by the receiving unit and an information amount of the request; a first determining unit that determines whether or not the port number coincides with a specific port number; a second determining unit that determines whether or not the information amount is equal to or greater than a specific threshold; and a system control unit that switches an operation mode from a power-saving mode to a normal mode when the first determining unit determines that the port number coincides with the specific port number and the second determining unit determines that the information amount is equal to or greater than the specific threshold.
