In accordance with the present invention, there are provided novel compounds that protect neurons andor promote neuroregeneration andor promote memory formation. The method includes the step of including a plurality of first tags in the DSI, each of the plurality of first tags corresponding to one of a plurality of multicast traffic channels having a plurality of logical channel identifiers ; and arranging the plurality of first tags in an order according to the LCIDs or a plurality of multicast control channels. The structure has a gate region, drain region and a source region. With this arrangement, the extension member may easily be secured and removed from the reduced-sized memory card, allowing easy interchangeability between a standard-sized socket of one electronic device and a reduced-sized socket of another electronic device. The displayed motion image is reduced to a magnification corresponding to the ratio of the rectangular frame with respect to the monitor frame. The technique comprises saving a term used in a first application; associating the term with the content; and rendering the content in a presentation associated with a second presentation.
