  • Patent number: 10235210
    Abstract: An operation management apparatus includes a storage unit and a processor. The storage unit stores therein operation scenario execution information including a first operation scenario and parallel execution information. The first operation scenario indicates an order of execution of a plurality of operation manipulations for a plurality of servers. The parallel execution information indicates whether the respective operation manipulations are to be executed in parallel with another operation manipulation. The processor acquires availability information indicating whether the respective servers are available. The processor generates execution determination information on basis of the operation scenario execution information when the availability information indicates existence of an unavailable server. The execution determination information indicates whether respective first operation manipulations are to be actually executed in execution of the first operation scenario.

  • Patent number: 9456745
    Abstract: In a fundus observation apparatus, an optical system detects interference light generated by superposing signal light having traveled by way of an eye fundus and reference light having traveled by way of a reference optical path. An image forming part forms a cross sectional image based on detection results of the interference light. A specifying part analyzes the cross sectional image to specify an abnormal region located in the vicinity of central fovea of the eye fundus. The association information generating part calculates the distance between the central fovea and the abnormal region and generates association information in which the direction of the abnormal region relative to the central fovea and the distance are associated with each other. The evaluation information generating part generates evaluation information for evaluating the state of the eye fundus based on the association information.

  • Patent number: 9340790
    Abstract: The present invention provides a novel method of producing a recombinant bacterium for production of a non-natural protein, including: (1) expressing tRNA in a bacterium, which tRNA recognizes UAG codon; (2) expressing an aminoacyl-tRNA synthetase in the bacterium, which aminoacyl-tRNA synthetase acylates the tRNA with a non-natural amino acid or an ?-hydroxy acid; (3) (i) introducing a DNA construct into the bacterium, which DNA construct is for expressing, in the absence of a release factor for terminating translation at UAG codon, a function of at least one gene selected from the group consisting of genes each of which loses its function when a gene that codes for the release factor is defective and/or introducing an alteration into said at least one gene in a chromosome of the bacterium, which alteration is for expressing the function of said at least one gene in the absence of the release factor; and (4) causing the gene that codes for the release factor in the bacterium to be defective.
