Abstract: The present invention relates to a novel siRNA structure and the use thereof, and more particularly to a double-stranded siRNA molecule comprising an antisense strand and a sense strand, wherein the siRNA molecule has at least one single nucleotide bulge formed by introducing a single nucleotide into the antisense strand, particularly at position 2 from the 5? end, and to a method of using the same to silence a target gene. The siRNA molecule of the invention shows high target gene silencing efficiency while minimizing off-target effects caused by the antisense strand, and thus has improved target selectivity. Accordingly, the siRNA molecule of the invention can be substituted for conventional siRNA molecules and can be widely be used in siRNA-based gene silencing techniques, including gene therapy.

Abstract: Disclosed are a distributed video encoding/decoding method and a distributed video encoding/decoding apparatus, which can improve loss resilience and the quality of service. The distributed video encoding method first involves checking the state of a channel, determining a channel coding rate and the size of video data to be transmitted based on the checked state of a channel, determining the number of motion prediction performance steps based on the determined size of video data to be transmitted, encoding the video data to be transmitted by performing motion predictions according to the determined number of motion prediction performance steps, and channel-coding the encoded video data according to the determined channel coding rate. Accordingly, it is possible to improve loss resilience, even without additionally occupying network resources, thereby being capable of reducing the probability of decoding failure.
