Abstract: The present invention relates to a heat exchanger and a bypass valve used in the heat exchanger, which are provided in consideration of cooling/heating performance. An object of the present invention is to provide a heat exchanger, which adopts a variable path in consideration of cooling/heating performance to solve a problem in which cooling performance and heating performance vary depending on the number of paths, and a bypass valve used in the heat exchanger. More specifically, another object of the present invention is to provide a heat exchanger, which is designed to change the number of paths in consideration of cooling/heating performance so as to be optimized for performance in a cooling mode and performance in a heating mode, and a bypass valve used in the heat exchanger.

Abstract: The present disclosure relates to a method for manufacturing a negative electrode for an all solid state secondary battery, including the steps of: (S1) preparing a preliminary negative electrode including: a current collector; and a negative electrode active material layer formed on at least one surface of the current collector, and containing a plurality of negative electrode active material particles and a solid electrolyte; (S2) disposing a lithium layer on the negative electrode active material layer; (S3) dipping the preliminary negative electrode having the lithium layer disposed thereon in an organic solvent; and (S4) removing the lithium layer. The present disclosure also relates to a negative electrode for an all solid state secondary battery obtained by the method. The negative electrode for an all solid state secondary battery provides improved initial efficiency and cycle characteristics.

Abstract: A pharmaceutical composition and a health functional food including an oat extract as an effective ingredient for prevention or treatment of neurodegenerative disease. More specifically, the present invention provides a pharmaceutical composition and a health functional food including an oat extract such as avenanthramide C or a derivative thereof, for example, avenanthramide methyl ester as an effective ingredient for prevention or treatment of Alzheimer's disease.

Abstract: A stent includes a magnesium layer, a ceramic layer formed over the magnesium layer, and a magnesium compound layer interposed between the magnesium layer and the ceramic layer. The initial corrosion of the stent can be delayed, and the stent has excellent biocompatibility and thus can reduce side effects during cell proliferation and differentiation.
