Security of ADS-B transmissions is improved in a first embodiment to detect position spoofing. The magnetic recording medium is provided with an orientation control layer, a nonmagnetic under layer, and a magnetic recording layer on a substrate. The jaw assembly includes a first jaw for receiving a first suture segment, and a second jaw for receiving a second suture segment such that the first and the second suture segments overlap. Specifically, the sound bite is embedded in a television signal that contains audio component and a video component. Thermal deterioration of the phosphor layer formed at the straight tube portions is reduced so deterioration of the initial light flux is suppressed, allowing lighting at higher efficiency. Categorized results are calculated and assessments regarding program difficulty and motivation of the subject may be formulated.
