Abstract: An information output device includes a first acquisition unit, a second acquisition unit, and an output unit. The first acquisition unit acquires supply information. The supply information is information capable of specifying the number of maintenance workers who perform maintenance on a target device for each of plural areas and for each of plural skills owned by the maintenance workers. The second acquisition unit acquires demand information. The demand information is information capable of specifying the required number of maintenance workers having the skill for each of the plural areas and each of the plural skills. The output unit outputs supply and demand information based on the supply information and the demand information in a specifiable mode for each of the plural areas.

Abstract: An information output device includes a first output unit and a second output unit. The first output unit acquires type specifying information capable of specifying a type of a maintenance target, acquires first work information indicating a first work for obtaining additional information on a state of the maintenance target using the type specifying information, and outputs the first work information to a communication device. The second output unit acquires additional information generated while performing the first work or after performing the first work, acquires second work information indicating a second work to be performed by an owner or a user of the maintenance target to perform maintenance on the maintenance target using the additional information, and outputs the second work information to the communication device.

Abstract: An information providing device provides a target space for performing training regarding maintenance of a maintenance target to a training subject, the target space being a virtual space or cross-reality, and includes an acquisition unit, a training data acquisition unit, and a providing unit. The acquisition unit acquires environment information. The environment information includes at least one of area information that can specify an area which the subject is in charge of and climate information on climate in the area. The training data acquisition unit acquires training data that is data related to the maintenance target and is to be reflected in the target space using the environment information. The providing unit executes processing for providing the target space reflecting the training data to the communication device used by the subject.

Abstract: An information processing apparatus includes at least one processor. The at least one processor carries out: a spatial information obtaining process of obtaining spatial information that includes information related to an object present in a three-dimensional space; and a position determination process of determining a position of the object present in the three-dimensional space with use of a plurality of planes, the plurality of planes being normal to respective axes that are independent of each other and being defined to traverse the entirety of the three-dimensional space.

Abstract: The present invention makes it possible, in a plant such as a thermal power plant, to prevent the corrosion of a piping member or a device such as a boiler by effectively decomposing nitrogen monoxide (NO) included in waste water or condensate water and inhibiting the generation of nitrous acid (HNO2). The present invention is a piping member used in a feed water system or a waste water system of a plant, and characterized by coating an inner wall of the piping member with a catalyst accelerating decomposition of nitrogen monoxide.
