Abstract: An intra prediction method and a device using the intra prediction method are provided. The intra prediction method includes the steps of: deriving a current prediction mode as a prediction mode of a current block; constructing neighboring samples of the current block with available reference samples; filtering the available reference samples; and generating predicted samples of the current block on the basis of the filtered available reference samples. The filtering step includes performing the filtering using the available reference sample located in the prediction direction of the current prediction mode and a predetermined number of available reference samples neighboring to the prediction direction of the current prediction mode.

Abstract: The present invention relates to a nanoformulated self-assembled pharmaceutical composition for photodynamic therapy. More particularly, the present invention is directed to a self-assembled pharmaceutical composition for photodynamic therapy comprising a photosensitizer, a ligand A which is separated at a specific pH range, and a ligand B of which surface charge changes at a specific pH range and a method for manufacturing the same.
