Abstract:
The present invention relates to a thin film comprising: carbon; oxygen; and a metal selected from a group consisting of aluminum, titanium, hafnium, tantalum, zirconium, and tungsten and, more particularly, to a metal-carbide-oxide thin film comprising, on the basis of the total atomic percentage: 5 to 85% of carbon, 5 to 60% of oxygen, and 5 to 40% of a metal. The metal-carbide-oxide thin film of the present invention is formed by being deposited through a single injection process of a reactant precursor, such that the thickness of a thin film may be reduced. Thus, it is possible to simplify processes and reduce manufacturing costs, and thus improve productivity. In addition, a method for manufacturing the metal-carbide-oxide thin film of the present invention may control the content ratio of each component in the thin film by changing deposition conditions, and thus may control the physical properties, such as strength, etch resistance, and conductivity, etc., of the manufactured thin film. Thus, it is advantageous to manufacture a thin film having properties suitable for the intended use.
Abstract:
The present invention relates to a pharmaceutical composition containing, as an active ingredient, a ChREBP expression or activity inhibitor, for preventing or treating diabetes. The pharmaceutical composition according to the present invention inhibits the expression or activity of ChREBP, which is a transcriptional factor of TXNIP, to inhibit the expression of TXNIP involved in the apoptosis of pancreatic beta cells, thereby having a beta cell protective effect, and thus the pharmaceutical composition can be favorably used in the prevention or treatment of diabetes.
Abstract:
The invention relates to a nano power-generating device, comprising: a base substrate; a hexagonal boron-nitride atomic layer formed on the base substrate; a first electrode formed on the hexagonal boron-nitride atomic layer; and a second electrode formed on the hexagonal boron-nitride atomic layer and spaced apart from the first electrode. The nano power-generating device of the present invention may operate in a continuous and independent manner using the piezoelectric characteristics of the hexagonal boron-nitride atomic layer.
Abstract:
The present invention relates to a composition for preventing or treating rheumatoid arthritis containing a gamma secretase inhibitor as an active ingredient. The gamma secretase inhibitor according to the present invention reduces the extent of arthritis induction and reduces the inflow of inflammatory cells into the knee joint, in a dose-dependent fashion, and also reduces the amount of cytokines and chemokines, and reduces the amount of expression of NICD (notch intracellular domain). Consequently, the gamma secretase inhibitor according to the present invention can be used as a medicinal product and a functional health food which is useful in the prevention or treatment of rheumatoid arthritis, since it regulates the activation, differentiation and growth of immune cells and hence has an outstanding effect in suppressing the production of NICD which plays a highly important role in notch signal transmission whereby inflammatory reactions occur.

Abstract:
The present invention relates to a context-specific experience sampling method comprising the steps of: collecting user characteristics and experience information; classifying the collected user experience information, and selecting a keyword for indicating the classified user experience information; generating a questionnaire, based on the keyword, to be used in an experience sampling; providing the user with the questionnaire; receiving, as an input, response data of the user to the questionnaire in connection with a video and audio recording device; and comparing and analyzing the response data inputted by the user and the video and audio data recorded by the video and audio recording device so as to analyze a relationship between experience and a situated environment.
Abstract:
The present invention relates to a method for transferring graphene using a hot press, comprising: a step of contacting graphene, having a heat-peelable sheet attached thereto, with a target substrate; and a step of pressing and heating the graphene having the heat-peelable sheet attached thereto and the target substrate using the upper press and lower press of a hot press so as to separate the heat-peelable sheet and the graphene and transfer the separated graphene to the target substrate. The present invention also relates to a graphene-transfer hot press apparatus for said transfer process.
Abstract:
