The image decoding method includes partitioning a picture into a plurality of coding units, constructing a coding unit group including at least one coding unit of the plurality of coding units, obtaining coding information in units of one coding unit group, and decoding at least one coding unit of the plurality of coding units included in the coding unit group by using the obtained coding information.

Abstract: Disclosed herein are a video decoding method and apparatus and a video encoding method and apparatus. In video encoding and decoding, multiple partition blocks are generated by splitting a target block. A prediction mode is derived for at least a part of the multiple partition blocks, among the multiple partition blocks, and prediction is performed on the multiple partition blocks based on the derived prediction mode. When prediction is performed on the partition blocks, information related to the target block may be used, and information related to an additional partition block, which is predicted prior to the partition block, may be used.

Abstract: The present disclosure relates to a method for producing an oral disintegrating film by a 3D printing technology which utilizes a hot-melt pneumatic extrusion method, and when a mixture including a poorly soluble drug, a film-forming polymer, and a plasticizer confirmed in the present disclosure was produced as an oral disintegrating film using the production method of the present disclosure, it was confirmed that the production method was simplified because the production process became one process, the production costs were decreased, and a poorly soluble drug having a problem in that bioavailability deteriorated due to an existing low solubility could obtain excellent solubility. The production method of the present disclosure that solves these problems can be utilized for many poorly soluble drugs, and thus can be widely utilized as a new method of utilizing a poorly soluble drug in the pharmaceutical field.
