  • Patent number: 10360090
    Abstract: A determination method includes obtaining, from a computer, history information of change time points indicating times at which processing for making a change to a program is executed; determining a predetermined time interval indicating an interval of the change time points; determining a first time period later than a latest change time point extracted from the history information, and a second time period earlier than the first time period; obtaining, from the computer, log messages including history of operations and operation time points corresponding to the operations; extracting, from the log messages, a first appearance pattern indicating a pattern of operations that appeared in the first time period and a second appearance pattern indicating a pattern of operations that appeared in the second time period; and determining whether a failure occurred in the first time period, based on a difference between the first appearance pattern and the second appearance pattern.

  • Patent number: 10318371
    Abstract: For each setting-file, an apparatus obtains, from first action-records, an occurrence-count value that is associated with the each first action-record and indicates a number of occurrences of a setting-item name identifying each setting-item for the each setting-file, in association with a sequence number assigned to the each first action-record, where each first action-record records an action that is taken in response to a first-incident. When there exists a first setting-file for which an occurrence-pattern generated based on a sequence of occurrence-count values that are each associated with different one of the sequence numbers assigned to the first action-records is similar to a model pattern that is in advance obtained from second action-records for second-incidents occurring due to a setting error of a setting-value that is set to the first setting file, the apparatus stores the first setting-file in association with an identifier identifying the first-incident.

  • Publication number: 20190040415
    Abstract: An object of the present invention is to solve problems in terms of stagnation of research on norovirus by providing a cultured transgenic cell or a transgenic animal in which murine norovirus (MNV) can be grown across the barrier of host specificity in mammalian cells, and providing a screening method that uses the cultured transgenic cell or the transgenic animal. The present inventors have found that MNV infection is determined in a cultured transgenic mammalian cell or a mammal possessing the cultured transgenic mammalian cell as its own cell, the cultured transgenic mammalian cell containing one or more species selected from the entirety or a portion of the murine CD300F gene and/or a CD300 family gene having an extracellular domain nucleotide sequence similar to that of the murine CD300F gene. The present inventors have solved the aforementioned problems by providing, for example, a norovirus-related drug screening method on the basis of this finding.
