Abstract: A window member includes a main part including a first side extending in a first direction, a second side extending in a second direction, and a first corner side connecting the first and second sides. The window member further includes a first side part in contact with the first side, a second side part in contact with the second side, and a first corner part connecting the first and second side parts. The first corner part includes a first upper corner part, a first middle corner part, and a first lower corner part. A lower surface of the first middle corner part has a first radius of curvature, a lower surface of the first lower corner part has a second radius of curvature, and the first radius of curvature is greater than the second radius of curvature.

Abstract: Provided is a peptide composition for preventing or treating Alzheimer's dementia. A peptide or a salt substituent thereof according to the presently claimed subject matter exhibits effects such as suppression of LPS-mediated cytokine production, suppression of LPS-induced neuroinflammation, amelioration of cognitive impairment, suppression of beta amyloid or tau protein aggregation, and suppression of neuronal loss. The polypeptide or the salt substituent thereof can permeate the blood-brain barrier, and thus, is expected to be usefully used for preventing or treating Alzheimer's dementia.

Abstract: A stretchable optical device comprises: a flexible substrate divided into M×N pixels; a first thin film sealing layer formed on the flexible substrate, located inside a pixel, and formed from a first inorganic material; an actuation device layer located inside the pixel and formed on the first thin film sealing layer; a light-emitting layer located inside the pixel and connected to the actuation device layer; a second thin film sealing layer located inside the pixel, formed on the light-emitting layer, coming into contact with the first thin film sealing layer, and formed from a second inorganic material; a third thin film sealing layer located inside the pixel, formed on the second thin film sealing layer, and formed from a composite material of an organic material and an inorganic material; and a flexible film adhered to the flexible substrate, the stretchable optical device divided into a high flexible area, which is dependent on the shape of the flexible film and has stretchable folds, and a low flexible

Abstract: Provided is a scalable video encoding method and apparatus, in which in adaptive reference fine grain scalability (AR-FGS) of scalable video coding, a weight value that is greater than a previous weight value provided for each slice overrides the previous weight value in order to generate a reference block for a enhancement layer when a macroblock mode of a base layer is a skip mode.

Abstract: Among other things, techniques, systems and apparatus are described for complementing a bitstream error so that a hardware decoder can stably decrypt a bitstream. A method of complementing a bitstream error includes: receiving a bitstream; detecting an error in the received bitstream; and complementing the detected error, before decrypting the bitstream.
