A liquid crystal display panel includes an upper substrate and a lower substrate opposite to each other, a liquid crystal layer interposed between the upper and lower substrates. The base has at least one conducting portion on the surface thereof on the side of the fixing member, and the image pickup element has a conducting portion on the surface thereof on the side of the fixing member. The invention provides viable gene knockout swine including swine in which the \u03b1-galactosyltransferase gene has been disrupted, methods for making such swine, and methods of using the tissues and organs of such swine for xenotransplantation. The electronic device further receives a power-off signal from the mechanical switch, and signals the driving circuit to turn off the electronic switch and discontinues the power supply to the electronic device. An encrypterdecrypter encrypts a conversation datum inputted with a newest common key, and transmits to other user terminals the encrypted conversation datum along with an index corresponding to the coordinated event used to generate the common key used to encrypt the conversation datum.
