Abstract: The present disclosure relates to a citrate synthase variant, a microorganism comprising the variant, and a method for producing L-amino acids using the microorganism.

Abstract: A pore-filled ion exchange polyelectrolyte composite membrane from which the surface ion exchange polyelectrolyte has been removed and a method of manufacturing the same are provided. The ion exchange polyelectrolyte composite membrane exhibits low film resistance and low in-plane-direction swelling degree, and has a smaller film-thickness than a commercial film, and thus, can be used for various purposes. In addition, since the pore-filled ion exchange polyelectrolyte composite membrane is continuously manufactured through a roll-to-roll process, the manufacturing process is simple, and manufacturing costs can be greatly reduced.

Abstract: The present invention discloses an encoding apparatus using a Discrete Cosine Transform (DCT) scanning, which includes a mode selection means for selecting an optimal mode for intra prediction; an intra prediction means for performing intra prediction onto video inputted based on the mode selected in the mode selection means; a DCT and quantization means for performing DCT and quantization onto residual coefficients of a block outputted from the intra prediction means; and an entropy encoding means for performing entropy encoding onto DCT coefficients acquired from the DCT and quantization by using a scanning mode decided based on pixel similarity of the residual coefficients.

Abstract: The present invention relates to stem cell-derived mature cardiomyocytes and a cardiovascular disease model using same and, more specifically, to differentiation into mature ventricular cardiomyocytes by culturing stem cells in a medium containing FGF4 and ascorbic acid, and use of the differentiated mature ventricular cardiomyocytes as a cardiovascular disease cell model. The mature ventricular cardiomyocytes, obtained by culturing stem cells in a medium containing FGF4 and ascorbic acid and inducing the differentiation thereof, and cardiovascular disease cell model using same according to the present invention are very useful for screening for cardiovascular disease therapeutic agents and evaluation of the toxicity of new drugs.

Abstract: Disclosed is a method of operating a mobile terminal that is capable of interworking with a server, and the method includes: displaying a first user interface (UI) for managing a to-do list of a terminal user on a display unit; registering a task to be performed by the terminal user as a to-do item in the to-do list based on user information input through the first UI, and managing the plurality of to-do items registered in the to-do list; and when at least one of the plurality of to-do items is selected, performing an operation related to a task corresponding to the selected to-do item.
