The present invention provides a method and apparatus in which a biometric information relating to a player is used to facilitate game play in multiplayer game environments. The apparatus provides a parking location search unit which manages a parking location of an individual vehicle by recognizing vehicle numbers by photographing vehicles entering a parking space and going out of there as well as parked vehicles, and provides related information upon search. In another embodiment, an inquiry message is sent to an application, the data is logged and execution of the access plan is continued or canceled if requested by a response to the inquiry message. The monitoring system detects movement of the wire at the portion while an electrical current having the same frequency as the mechanical resonant frequency of the wire is sent through the wire and a magnetic field surrounds the portion. The flow passage is formed in the outlet between the bottom seat, the neck and the head and has at least one inlet hole and an outlet hole. Control logic generates the switching control signals responsive to a pulse control signal.
