    • An extraction unit of fault assumption and a finish-point FF is provided, the fault assumption is selected from fault assumption information, and a logic trace is executed from the fault assumption toward an output side. A test result of a finish-point FF obtained as a result of the trace from the fault assumption is determined. The maximum value and the minimum value of the propagation route up to the finish-point FF are determined, and a delay margin is determined from the values. A delay range is determined by using the delay margin and the test result, and a fault candidate and a delay range of the delay fault are specified by the process of the determination of the fault candidate and the delay range.

    • An ultraviolet curable composition having, a coating film cured with ultraviolet rays with a large number of crosslinking points due to a (meth)acrylate compound that does not intramolecularly have a cyclic moiety and has a functionality of three or more and, the compound does not intramolecularly have a cyclic moiety, plastic deformation due to a cyclic moiety is less likely to occur. Additionally, a monofunctional (meth)acrylate compound forms a homopolymer having a glass transition temperature of 20° C. or less, has a low glass transition temperature, and is flexible. Curing contraction caused in ultraviolet curing is suppressed and plastic deformation is less likely in the resultant cured film at room temperature. An optical disc employing the above ultraviolet curable resin composition reduces warpage; and rapid recovery from deformation caused even by application of a load for a long period of time or as a result of an impact due to falling.

    • To provide a database which has plural log storage areas, and eliminates the sort in the restoration process by means of the application of logs, thereby carrying out the restoration quickly. A management server allocates DB servers to a corresponding one of plural data storage areas so as to access the corresponding one. The DB servers store data to the allocated data storage areas. When the data is referenced or updated, a log representing a data change history is stored in preset log areas for each data server. When the management server transmits a notification to change the data storage areas, area remapping logs are stored in log areas.
