Abstract: Disclosed is a French artificial nail including an artificial nail body and a French part. The artificial nail body includes a cuticle edge facing the root of a fingernail and a free edge extending towards the tip of the fingernail and is curved downward toward both lateral sides thereof to form a curved surface. The French part is formed on the upper surface of the free edge of the artificial nail body. The artificial nail body is attached to a user's fingernail or toenail through glue and has a lower modulus than the French part. This flexibility of the artificial nail body prevents the formation of bubbles, the incidence of pain and the occurrence of pop-off resulting from glue shrinkage, contributing to an improvement in the wearability and reliability of the final product.

Abstract: A method of collecting peer-to-peer (P2P)-based content sending/reception information is disclosed herein. In the method of collecting P2P-based content sending/reception information, a first peer accesses a second peer, and exchanges buffer maps with the second peer.

Abstract: Disclosed herein are a method and apparatus for processing MMTP packets. When an MMTP packet is transmitted, the packet processing apparatus calculates a reference value from partial field values of a reference MMTP packet header, and inserts the calculated reference value into the compressed header. By the reference value, MMTP packets may be correctly distinguished and may be correctly referred to when there are two reference MMTP packets in which the lower 5 bits of packet sequence numbers are identical to each other, or even when the number of reference MMTP packets is a multiple of 256.
