A method and apparatus for compensating for the luminance of a color signal. The stresses are reduced by extending the thermal barrier coating below the radius between the outer band perimeter and the inner flow path surfaces and tapering the coating thickness. The frame design allows the entire frame to be formed of cardboard and still provide adequate rigidity and strength. These hyper links are used for performing search operations in realization data equivalent to those which are possible in representation data, enabling an improved access to the realization. The first module includes a module recognition unit recognizing whether the communication module of the terminal is within a preset distance; and a memory unit storing network configuration information to be used when the second module accesses the router.
