A switching power supply circuit ready for worldwide use is disclosed which suppresses a variation of a pulse voltage to be fed back when the alternating-current input varies. Other video processing methods include receiving a query for a video frame and searching for event data in a database. The second module performs a second current command on a switching line set at a retard angle side relative to the maximum efficiency characteristic line. The movable element or elements, preferably placed between fixed elements, are displaceable in a more or less vertical direction. Treatments for subjects based upon levels of K41-glycated CD59 also are provided. The updated fragment may or may not be cached.
