Abstract: A light-emitting element includes a first end portion and a second end portion disposed in a length direction of the light-emitting element, a first electrode corresponding to the first end portion, a first semiconductor layer on the first electrode, an active layer on the first semiconductor layer, a second semiconductor layer on the active layer, and a second electrode on the second semiconductor layer and corresponding to the second end portion. The second electrode includes a first layer on the first semiconductor layer, and a second layer on the first layer. The first semiconductor layer includes a p-type semiconductor layer doped with a p-type dopant. The second semiconductor layer includes an n-type semiconductor layer doped with an n-type dopant. The first electrode is in ohmic contact with the first semiconductor layer. The second electrode is in ohmic contact with the second semiconductor layer.

Abstract: The present invention provides an immunogenic composition comprising a Streptococcus pneumoniae polysaccharide-protein conjugate, comprising a capsular polysaccharide derived from one or more selected from the group consisting of serotypes 1, 2, 3, 4, 5, 6A, 6B, 7F, 8, 9N, 9V, 10A, 11A, 12F, 14, 15B, 17F, 18C, 19A, 19F, 20, 22F, 23F, and 33F, derived from Streptococcus pneumoniae; and one or 2 or more of carrier proteins conjugated to the respective capsular polysaccharide, and method of preparation thereof. Through one example of the present invention, an immunogenic composition for preventing or treating pneumococcal infection can be provided.

Abstract: A display device for selectively adjusting a viewing angle thereof and a method of adjusting a viewing angle thereof are provided. The display device comprises: a display unit displaying an input image based on a determined viewing angle; and a controlling unit determining a viewing angle of the display unit according to a predetermined viewing condition and controlling to display the input image with the determined viewing angle, wherein the viewing condition is one of a viewer position condition, an image type condition, and a viewer setting condition.

Abstract: A display apparatus includes: a command receiver configured to receive power on or off command from an exterior, a power supply unit configured to supply power to the display apparatus and a control unit coupled to the command receiver and the power supply unit, determining whether auxiliary power exists when the power off command is received, wherein the control unit is configured for two power saving modes.
