Abstract: An embodiment method for using a part supply system to load and supply parts required for processes in producing a mobility includes creating, by a processor, a part supply schedule in which the parts required for the processes in producing the mobility for each of a plurality of time zones are scheduled, creating, by the processor, a part loading schedule in which the parts to be loaded on each work bench to which the pails are supplied according to the part supply schedule for each time zone are scheduled, verifying, by the processor, whether the part loading schedule satisfies the part supply schedule through a digital twin, and confirming or modifying, by the processor, the part loading schedule based on the verification through the digital twin.

Abstract: A portable terminal comprises: a terminal body having a receiver for sound output; a first antenna disposed in the terminal body, and operating at a first band; a second antenna disposed at a position different from the first antenna, and operating at a second band, wherein the second antenna comprises: a first conductor having a physical condition to be operable at the second band; and a second conductor having a physical condition to resonate an electromagnetic wave of the first band so as to reduce a field strength of the first band near the to receiver.
