Abstract: A failure symptom detection system includes a first storage to collect and store field data of each of a plurality of Internet of things devices, a feature extractor to acquire feature data of the field data based on a report on a failure in a service as a feeling of a user of a facility, a second storage to accumulate a failure at an occurrence of the failure associated with content of the failure as the feeling of the user, and a failure symptom detector to monitor the field data stored in the first storage, and produce, upon detecting feature data matching the feature data accumulated in the second storage, output indicating detection of a symptom of the failure associated with the feature data.

Abstract: A link management device, concerning development management data utilized by each of a plurality of development management systems included in a tool chain system, manages a link between items of the development management data. A link registration unit executes crawling of acquiring, from each of the plurality of development management systems, information of the development management data including naming information indicating naming of the development management data. Then, based on the information of the development management data, the link registration unit transmits a link registration instruction for registering the link between the items of the development management data to the plurality of development management systems. Then, the link registration unit records the link between the items of the development management data, as link record information.

Abstract: Provided is an information linkage device for causing information in a chat server that manages chat information to be reflected in an information management system that manages action item information. The information linkage device includes a control unit for analyzing information handled in a chat transmitted/received to and from the chat server via a network and acquiring action item information, and transmitting the action item information to the information management system.

Abstract: A floating floor comprises a plurality of square buffer members arranged in parallel at regular intervals on a supporting structural floor, a plurality of floor panels vertically spaced above the supporting structural floor by the supporting members to form an air layer between them. The floor panels are respectively provided with a plurality of air holes through which the air layer is communicated with the outside of the floor panels. The floor panel may be a hollow panel having a plurality of cavities extending in parallel in the longitudinal direction of the panel and being opened at butt ends of the panel, each cavity being communicted with the air layer through said air holes to form passages from the air layer to the outside of the floor panel. Instead of square buffer members, there may be used square supporting members and a buffer layer so that the floor panels are vertically spaced above the buffer layer by square supporting members to form an air layer between them.
