Abstract: A method and apparatus for multiplexing and de-multiplexing video data. The method of multiplexing the video data involves syntax to a header of transmission unit data that is used to multiplex a clean random access (CRA) picture used in a random access, wherein the predetermined syntax indicates a reproduction status of the CRA picture, i.e., normal reproduction or reproduction according to a random access.

Abstract: Provided are a separation and recovery device for a liquid waste including a radionuclide, and a separation and recovery method using the same. Specifically, the present disclosure relates to a separation and recovery device that may effectively separate a liquid waste, such as a waste detergent including a radionuclide, and simultaneously, may prevent the release of tritium and radiocarbon to the outside, and a separation and recovery method using the same.

Abstract: An intra prediction method includes searching for a neighboring block restored prior to a current block from among blocks of an image; checking whether the neighboring block found by the searching is a block restored in an intra mode and whether an intra mode of the current block is also a Combined Intra Prediction (CIP) mode in which only blocks pre-restored in the intra mode are referred to; determining based on a checking result of the checking whether the found neighboring block is a reference block available for intra prediction of the current block; and performing intra prediction on the current block by using sample values of the reference block determined as available for the intra prediction of the current block.

Abstract: A reuse apparatus of eutectic salt waste produced in an electro refining process and a method thereof is a technology that in order to collect the eutectic salt of the eutectic salt waste, oxidizes/precipitates nuclides (rare earth and TRU) within the eutectic salt waste, an oxygen dispersing method is used to perform a layer separation into the eutectic salt layer and the precipitate layer. Then, the precipitate layer and eutectic salt layer are separated and collected, so that the eutectic salt layer is directly reused and the eutectic salt within the precipitates is reused by separating and collecting it using distillation/condensation processes. The reuse apparatus of the eutectic salt waste and a method thereof thereby increases the collecting efficiency of the eutectic salt and allows the compositions of the collected eutectic salt to have the same compositions as the eutectic salt used in the electro refining process.
