Provided is a formed article including a layer obtained by implanting ions of a hydrocarbon compound into a polysilazane compound-containing layer. The write-back determination unit determines whether a block is a write-back block based on an n-bit dirty value of the block. Light beams emitted from the input array are reflected by the corresponding mirrors to be sent to the output array in the operation state, and pass near the corresponding mirrors in the standby state. Specifically, system monitors the vehicle center of gravity for changes on a real-time basis, and then adjusts the risk predictionassessmentanalysis system responsively.
