More specifically, various types of data required for operation (e.g., inspection, examination, maintenance, repair, and reinforcement) of an industrial installation are digitalized, extended reality content, such as an augmented reality image or a mixed reality image based on the digitalized data, is provided to a site worker or a remote place manager, and the worker and the manager can communicate via a video call in real-time, whereby the work efficiency of the worker and the manager can be enhanced.

A value element determination device according to an embodiment includes: an input unit for inputting a function of an evaluation target service and a standpoint of a user using the evaluation target service; a first calculation unit that uses a relevance matrix having relevance between the function of the evaluation target service and each of state-changes of the user using the evaluation target service as elements to calculate the relevance between the function input via the input unit and each of the state-changes; an acquisition unit that acquires, from a database storing sets of the state-change of the user using the evaluation target service and advantage or disadvantage of the user using the evaluation target service, a set including a state-change having the relevance calculated by the first calculation unit exceeding a threshold value; a second calculation unit that calculates similarity in terms of meanings of the advantage or disadvantage included in the set acquired by the acquisition unit, the standpoint of the user input via the input unit, and an evaluation element representing an element configuring evaluation of the evaluation target service; and an output unit that outputs the evaluation element having the similarity calculated by the second calculation unit exceeding the threshold value.

A marine vessel management system to reduce the burden on a marine vessel rental business operator includes a marine vessel, an information processor, and a portable terminal device operable by a marine vessel user. When the marine vessel is leaving a port and/or when the marine vessel is returning to the port, the portable terminal device receives information about a state of the marine vessel via the information processor, and displays the received information about the state of the marine vessel.

A management system is configured to include a first data acquisition unit, a second data acquisition unit, and a comparison unit. The first data acquisition unit acquires first image data obtained by capturing an image of a first object, and identification information about the owner of the first object. The second data acquisition unit acquires second image data obtained by capturing an image of a second object. The comparison unit 3 identifies the identification information about the owner of the first object by comparing the characteristics of the surface pattern of the first object as represented by the first image data with the characteristics of the surface pattern of the second object as represented by the second image data.

One example method includes receiving configuration information for a virtual expo, the configuration information includes information associated with one or more virtual expo booths; generating a virtual expo floor based on the one or more virtual expo booths; establishing a virtual meeting comprising the virtual expo; receiving requests to join the virtual expo from a plurality of client devices; joining each client device of the plurality of client devices to the virtual meeting; providing, to each joined client device, information describing the virtual expo floor and locations of each of the one or more virtual expo booths; providing a location of a respective participant avatar on the virtual expo floor; receiving, from a first client devices, a selection of a first virtual expo booth; and join the first client device to a second virtual meeting associated with the first expo booth.

A control method is executed by a first node holding a first distributed ledger in which a first blockchain is managed, and includes: obtaining, from a second node, a second blockchain managed by a second distributed ledger held by the second node, and comparing the second blockchain with the first blockchain; updating the first blockchain by adding the greater of at least one first different block contained in the first blockchain but not the second blockchain and at least one second different block contained in the second blockchain but not the first blockchain, after at least one common block, and adding at least one additional block containing at least one instance of transaction data contained in the lesser; and determining whether at least two instances of transaction data each containing at least two instances of contract information that conflict with each other are contained in the updated first blockchain.

An information management system includes a reception device including a camera that images a face of a participant, and an information management apparatus. The information management apparatus issues a digital key assigned for each participant independently of personal information of the participant and transmits the digital key to the reception device. In a case where the reception device outputs an ID image of the participant, the information management apparatus acquires a face image from the reception device and stores the face image and the digital key in a database in association with each other. In a case where information including the digital key is received from a reading device installed in an event venue, the information management apparatus stores the received information in the database in association with the digital key as behavior information representing a behavior of the participant in the event venue.

Provided is a video distribution system with which it is possible to improve the motivation of participants with respect to an event that is distributed as a recorded video. A video distribution system is connected via a network to user terminal devices, and distributes a recorded video obtained by recording status of a game event in which a plurality of participants participating therein, to the user terminal devices. And the video distribution system increases the prize money amount set for the game event according to selection of an amount increase option executed by each user via the user terminal device so as to be associated with the recorded video, and decides the individual prize money amount to be awarded to a target participant P based on the prize money amount at the end of a predetermined period.

The present disclosure provides a liquid detection sensor which has the general purpose usability and can prevent the deterioration of a metal-air battery being an electric power source even when being installed for a long term, and in which the metal-air battery being an electric power source can exhibit an excellent electric power generation performance. The liquid detection sensor has the metal-air battery having a positive electrode, a negative electrode, and an electrolytic solution-forming component positioned between the positive electrode and the negative electrode, wherein the electrolytic solution-forming component is enclosed in the inside of a resin-made bag; and a resin of the resin-made bag has dissolvability or dispersibility in a liquid being an object to be detected.
