Abstract: The present application relates to a sweetener including an oligosaccharide having increased acid resistance, a food composition including the same, and a method of increasing acid resistance of an oligosaccharide of an oligosaccharide-containing sweetener including applying allulose to the oligosaccharide.

Abstract: Disclosed is an anti-adhesion agent composition which uses a high molecular weight compound having biocompatibility and an oil derived from animals, plants, and minerals so as to improve low viscosity and low strength, which are problems of existing anti-adhesion agents, and prevent adhesion between living tissues. The anti-adhesion composition according to the present disclosure performs a physical barrier function through simple mixing of a polymer material, serving as a physical barrier in its anti-adhesion effect, and a solvent, and remains in the body for a certain period of time, then decomposes, absorbs, and is excreted. The anti-adhesion composition does not interfere with the healing of the wound after surgery, and exhibits an excellent effect of convenient application to the surgical site.

Abstract: A negative electrode active material as well as a method of preparing a negative electrode active material which includes preparing a silicon-based compound including SiOx, wherein 0.5<x<1.3; disposing a polymer layer including a polymer compound on the silicon-based compound; disposing a metal catalyst layer on the polymer layer; heat treating the silicon-based compound on which the polymer layer and the metal catalyst layer are disposed; and removing the metal catalyst layer, wherein the polymer compound includes any one selected from the group consisting of glucose, fructose, galactose, maltose, lactose, sucrose, a phenolic resin, a naphthalene resin, a polyvinyl alcohol resin, a urethane resin, polyimide, a furan resin, a cellulose resin, an epoxy resin, a polystyrene resin, a resorcinol-based resin, a phloroglucinol-based resin, a coal-derived pitch, a petroleum-derived pitch, a tar and a mixture of two or more thereof.

Abstract: The present invention relates to a heteroaryl derivative compound and a use thereof. Since the heteroaryl derivative of the present invention exhibits excellent inhibitory activity against EGFR, the heteroaryl derivative can be usefully used as a therapeutic agent for EGFR-associated diseases.

Abstract: The present invention includes a jig for installing a protection member to a portable electronic device and a guide jig device including the same. The jig includes a main body and retaining members formed to be elastically deformed and coupled or connected to the main body while surrounding a mounting space in which the portable electronic device formed in the main body is inserted. The guide jig device is advantageous in that it can be used for a portable electronic device that is manufactured and sold in a size relatively greater than the size of the portable electronic device disclosed before its release.

Abstract: A device for installing a screen protector to an electronic device that includes a screen protector unit having a release film, a screen protector, and a protection film wherein the release film has a release tab, the protection film has at least one protection tab where the protection tab includes a hole formed therein; a tray having a panel, at least one alignment protrusion that fits the hole, a guide hole to allow external pressure to be applied onto the screen protector unit when the screen protector unit and the electronic device are received in the tray; and an adhesive strip, via the guide hole, further secures the screen protector unit to the tray. Also included is a method to using the device to install the screen protector to the screen of the electronic device.
