Abstract: A light emitting component includes: a substrate; a plural light emitting elements that are provided on the substrate and respectively have light emission regions; and a plural thyristors that are turned on to cause the light emission regions of the respective light emitting elements to emit light, or that increase amounts of emitted light of the light emission regions, in which the light emitting elements absorb light emitted from a corresponding thyristor among the plural thyristors.

Abstract: A network operation monitoring system comprising a memory unit for storing network status information in a time series with respect to each operation performed by an operator on a network or with respect to each transition in events, a retrieval unit for retrieving the network status information stored in the memory unit in a time-dependant manner according to the operator's instruction, and a display unit for displaying the network status information retrieved by the retrieval unit in the time-dependant manner according to the operator's instruction.
