It is an object to provide a hair dressing and beauty technique training device by which the presence or absence of twist or angle shift in a horizontal direction when drawn by sandwiching between the fingers is easily found, thus a proper posture for haircutting and winding etc. The method includes the steps of measuring the complex reflectivity of the multi-layered structure at a wavelength outside of the bandgap of the multi-layered structure and calculating a complex coupling coefficient from the measured complex reflectivity of the multi-layered structure continuously or at intervals during the formation process. The delivery means can comprise a lumen 21 containing the bio-active substance in a liquid form. The UMC accepts memory requests from various clients, and determines which requests should receive priority access to the unified memory. Moreover, the first subframe frame and the second subframe can be transmitted. An out-of-order execution pipeline executes the microinstructions to generate results specified by the instruction.
