Abstract: Disclosed is an avatar creation method including creating a base object of an avatar, creating at least one partial object; acquiring customizing information of a user, deforming the base object and the at least one partial object based on the customizing information; and creating a user avatar with a default facial expression by projecting the at least one partial object onto the surface of the base object.

Abstract: First electronic device includes a communication interface and a processor. The processor is configured to: receive, from the second electronic device, an incoming message destined for the first electronic device, transmit, to the third electronic device, message information related to the incoming message, the message information being used for displaying the incoming message on the third electronic device, transmit preset texts to the third electronic device, the preset texts being stored in the first electronic device to be used for replying to messages receivable by the first electronic device, based on one of the preset texts being selected by a user input among the preset texts displayed on the third electronic device, receive response information from the third electronic device, the response information being related to the one of the preset texts, and transmit, to the second electronic device, a response message including the one of the preset texts.

Abstract: A pharmaceutical composition including a compound of Formula 1 may be used for preventing or treating dengue fever. Specifically, the composition may include ulipristal, ulipristal acetate, or a pharmaceutically acceptable salt thereof, which may inhibit dengue virus infection. The dengue fever may be caused by infection with dengue virus DENV-1, DENV-2, DENV-3 or DENV-4.

Abstract: Provided are an image compression method and apparatus for differentially encoding digital image signals based on a Joint Photographic Experts Group (JPEG) image compression standard. RGB image signals are converted to luminance and chrominance data. Pixels of converted chrominance components are compared, difference values between the compared pixels are obtained, and representative pixel values are determined by comparing the obtained difference value and an allowable error. The representative pixel values are encoded. A data compression ratio can be improved by discrete-cosine-transforming only portions of an image having different colors from a background color.
