Abstract: A mobile device is disclosed. The device includes a communicator, a GPS unit for calculating location information, a memory, a display, and a processor, and the processor is configured to generate movement path information of the mobile device by performing homomorphic encryption of a plurality of pieces of location information stored in the memory, transmit the movement path information to a server apparatus through the communicator, based on operation result data obtained by operating based on the movement path information and comparison target path information being transmitted from the server apparatus, decrypt the operation result data, and output a message notifying whether a route overlaps the comparison target path information based on a decrypted result through the display. Therefore, the route overlap is rapidly and accurately confirmed without invasion of privacy.

Abstract: A flat panel for a cathode ray tube includes a faceplate portion, a skirt portion and a blend round portion joining the faceplate portion with the skirt portion. A point where an external contour of the faceplate portion meets an external blend round contour of the blend round portion is defined as a first point and a point where an external contour of the skirt portion meets the external blend round contour is defined as a second point. The external blend round contour is formed between an imaginary arc whose end points coincide with the first and second points and a line segment whose end points coincide with the first and second points, or is the line segment. The imaginary arc is smoothly connected to the external contours of the faceplate portion and the skirt portion at the first and the second point.
