  • Patent number: 9973388
    Abstract: A processor of a server information management apparatus detects an added server to a management target system. Also the processor specifies an attribute of the added server based on a communication state of the added server, first management information related to the added server, and second management information related to a communication destination server of the added server. Therefore, it is possible to precisely determine an attribute of a server which is added to a business system.

  • Patent number: 9596133
    Abstract: A disclosed method includes: specifying an activity to be executed, based on process definition that includes plural activities, and that includes a sequence of transitions between activities, wherein each activity includes information representing a device that is operated through a network; first determining, based on the sequence of the transitions, whether or not the specified activity is an initial operation for a certain device whose information is included in the specified activity; and obtaining an access right to the certain device, when determining that the specified activity is the initial operation for the certain device.

  • Patent number: 5447926
    Abstract: A quinolone carboxylic acid derivative having the following formula (1), ##STR1## wherein R.sup.1 is a hydrogen atom, an alkyl group, an aralkyl group, an ester residual group which can be hydrolyzed in living bodies, R.sup.2 is a hydrogen atom or an amino group which may be substituted by one or two lower alkyl groups, X is a hydrogen atom or a halogen atom, Y is CH.sub.2, O, S, SO, SO.sub.2, or N--R.sup.3, wherein R.sup.3 is a hydrogen atom or a lower alkyl group, and Z is an oxygen atom or two hydrogen atoms; or a salt thereof; and an antimicrobial agent comprising the same. The compound exhibits a superior antimicrobial activity, especially against gram positive microorganisms, and is thus useful for the treatments and prevention of various infectious diseases in clinics.

  • Patent number: 5147886
    Abstract: A triazole derivative is disclosed. The compound have a general formula, ##STR1## wherein R.sup.1 and R.sup.2 represent a hydrogen atom or a lower alkyl group, or R.sup.1 and R.sup.2 together form a lower alkylene group, R.sup.3 represents a lower alkyl group, and n denotes an integer of 0 to 2, provided that not both R.sup.1 and R.sup.2 are a hydrogen atom at the same time. The triazole derivatives and their salts are effective for curing or preventing deep-seated mycoses, e.g. mycotic meningitis, mycotic infectious diseases of respiratory organs, fungemia, and urinary tract mycosis.
