Abstract: Disclosed are an image encoding method using a skip mode and a device using the method. The image encoding method may comprise the steps of: judging whether there is residual block data of a prediction target block on the basis of predetermined data indicating whether residual block data has been encoded; and, if there is residual block data, restoring the prediction target block on the basis of the residual block data and an intra-screen predictive value of the prediction target block. Consequently, encoding and decoding efficiency can be increased by carrying out the encoding and decoding of screen residual data only for prediction target blocks where there is a need for a residual data block in accordance with screen similarity.

Abstract: The present disclosure relates to an anti-miRNA delivery system, and more specifically, relates to a technique of using a cancer-targeting anti-miRNA delivery system including porous silicon nanoparticles containing anti-miRNA to which a cancer cell surface protein-binding peptide is conjugated, for use in treating cancer. As a result of intensive studies in order to use and apply anti-miR-21 oligonucleotides to the treatment of ovarian cancer, the present inventors confirmed for the first time that when porous silicon nanoparticles containing an anti-miRNA-21 oligonucleotide to which a specific cancer cell surface protein-binding peptide is conjugated are applied, apoptosis is induced in an ovarian cancer cell line and cell viability is reduced, thus, an anti-miRNA delivery system, which is the aforementioned conjugate, is expected to be usefully used as a platform for treating various cancers, especially for treating ovarian cancer.
