An FM broadcasting station broadcasts paging ID by multiplexing it on FM broadcasting radio waves in a subframe period assigned in advance to an FM radio receiver 1b to be paged, and broadcasts, as program data, message data directed to the FM radio receiver 1b to be paged. Registrations are made as sale registration data of not only at least one real-goods displayed in a real-shop and ordered by a purchaser but also at least one online-goods displayed in at least one virtual-shop and ordered by the purchaser, before accomplishing a batch accounting operation for the at least one real-goods and the at least one online-goods registered on the sale registration data. The bracket may include a housing of a lighting fixture with the pair of threaded shafts passing through the diffuser and into the housing. The method also includes detecting a sterilization event. Planar, relatively rotatable and mating flanges located at the exit end of the entry member and the input end of the exit member provide a common centerline and are joined by means of a threaded collar, thereby permitting configuration of the swivel fitting at angles between about 90 and 180 degrees. With the invention measurements can be performed in objective manner with which an objective judgment in respect of the presence of a cervical acceleration injury in the person in question can be obtained.
