Abstract: There is provided an image decoding method comprising: deriving a first prediction value of a current block by using at least one sample included in a reference block, obtaining an illumination compensation parameter on the basis of a predetermined reference region, deriving a second prediction value of the current block by applying the illumination compensation parameter to the first prediction value and reconstructing the current block on the basis of the second prediction value.

Abstract: Provided is an apparatus and method for encoding/decoding a moving picture based on adaptive scanning. The moving picture apparatus and method can increase a compression rate based on adaptive scanning by performing intra prediction onto blocks of a predetermined size, and scanning coefficients acquired from Discrete Cosine Transform (DCT) of a residue signal and quantization differently according to the intra prediction mode. The moving picture encoding apparatus includes: a mode selector for selecting and outputting a prediction mode; a predictor for predicting pixel values of pixels to be encoded of an input video based on the prediction mode to thereby output a residue signal block; a transform/quantization unit for performing DCT onto the residue signal block and quantizing the transformed residue signal block; and an encoder for adaptively scanning and encoding the quantized residue signal block based on the prediction mode.

Abstract: A yarn including a plurality of twists formed by twisting single fiber strand or multiple fiber strands; and fiber grooves, which are spaces formed between the twists, to provide three-dimensional growth spaces and migration paths for cells. Accordingly, a cell proliferation rate and cell viability may be enhanced by creating microenvironments suitable for migration, proliferation and differentiation of cultured cells. In addition, cell clusters having more uniform shapes may be easily implemented by forming the proliferation spaces and migration paths for the cultured cells as similar as possible to each other in each scaffold. Further, the cells cultured thereby can be cultured in a suitable shape and structure to be applied to an in vitro experimental model or transplanted into the body of an animal, and can be widely applied in various products used in a cell culture or tissue engineering field.

Abstract: A peptide has the sequence of X-(L)n-Y, wherein one of X and Y is an amino acid sequence of an elastin-like polypeptide, the other is an amino acid sequence of SEQ ID NO: 2, L is a linker sequence, and n is 0 or 1. By using the peptide, rare earth elements can be recovered with high yield from a sample including the rare earth elements. In addition, the peptide can be used repeatedly, and can also minimize environmental pollution problems since the peptide corresponds to a biosorbent, and thus has very high industrial applicability.

Abstract: A method and device for predicting errors in a computing system are disclosed. The error prediction method includes: receiving log data generated by the computing system during operation of the computing system; tokenizing the log data into tokens; inputting the tokens to a discriminator model which generates scores of the respective tokens, each score corresponding to a probability that the corresponding token is an anomaly token; determining an anomaly score based on the scores; and determining a likelihood of future occurrence of an error in the computing system based on the anomaly score.

Abstract: Disclosed herein are a video processing method, apparatus and storage medium using the resolution of a reference picture. Filtering is performed based on resolutions of reference pictures of blocks forming a boundary. The resolutions of the reference pictures may define filtering. Depending on whether the resolutions of the reference pictures are different from each other, one or more filter selection parameters for filtering may be determined or updated. Further, based on whether the resolutions of the reference pictures are different from each other, the boundary strength of the filter may be determined. Because filtering is defined using the resolutions of reference pictures, performance of encoding and/or decoding may be improved.

Abstract: The present disclosure provides a compressor including a rounded portion surrounding a discharge port, including a cylinder without an oil-blocking structure for ease of shaping the rounded portion, and including a valve-recess cover coupled to the cylinder. At least one valve-recess is defined in an outer face portion of the cylinder. A discharge valve assembly is fixedly received in the valve-recess, wherein the discharge valve assembly is configured for opening and closing the discharge port. The valve-recess is defined between the outer face, primary and secondary side blocks. The rounded portion surrounds the discharge port, to reduce a contact area between the discharge port and the valve assembly.
