Abstract: A selector according to an embodiment of the present disclosure includes a first electrode; a second electrode disposed opposite to the first electrode; an ion supply layer disposed between the first electrode and the second electrode to be on the side of the first electrode and doped with a metal, wherein the doped metal diffuses toward the second electrode; a switching layer disposed between the first electrode and the second electrode to be on the side of the second electrode, wherein the doped metal diffuses from the ion supply layer into the switching layer so that metal concentration distribution inside the switching layer is changed to generate metal filaments; and a diffusion control layer inserted between the ion supply layer and the switching layer, wherein the diffusion control layer serves to adjust electrical characteristics related to the generated metal filaments as the amount of the diffusing metal is adjusted in proportion to a thickness of the diffusion control layer.

Abstract: A filtering panel includes a molding layer part; a pattern layer part having an incident surface through which light emitted from a light source and viewing light transmitted to an observer enter, and an accommodation surface which is the reverse surface of the incident surface, wherein the molding layer part is stacked on the incident surface so as to be adjacent thereto, and the pattern layer part adjusts the optical paths of the emitted light and the viewing light; and a filtering layer part formed on a lower incident surface of the pattern layer part having the incident surface of the viewing light that enters from a lower region below a horizontal reference line, wherein the reflectivity of the visible light in the viewing light incident on the lower region is made greater than that of an upper region above the reference line by means of mirror reflection.

Abstract: The present invention relates to a composition for relieving a hangover or a composition for preventing, alleviating or treating alcoholic liver disease, comprising a ?-glucan as an active ingredient.

Abstract: The present invention relates to a composition for use in preventing, alleviating, or treating inflammatory disease, or an anti-inflammatory composition, which comprises: ?-1,3-glucan; and the peptide composed of the amino acid sequence of SEQ ID NO: 4. The present invention also relates to an antibacterial composition against bacteria causative of sepsis, which comprises: ?-1,3-glucan; the peptide composed of the amino acid sequence of SEQ ID NO: 4; and an antibiotic. The present invention also relates to a method for preventing or treating an inflammatory disease, the method comprising a step of administering ?-1,3-glucan; and the peptide composed of the amino acid sequence of SEQ ID NO: 4 to a patient.

Abstract: The present invention relates to a pharmaceutical composition for treating a wound or activating the skin, containing beta-glucan, glycitin (4?-hydroxy-6-methoxyisoflavone-7-D-glucoside), and 4?,6,7-trimethoxyisoflavone.

Abstract: The present invention relates to a composition for relieving a hangover or a composition for preventing, alleviating or treating alcoholic liver disease, comprising a ?-glucan as an active ingredient

Abstract: The biochemical oxygen demand (BOD) of aqueous liquids containing organic matter is determined. A microorganism culture is aerated to exhaust the organic matter available to the microorganisms. An aqueous liquid test sample containing organic matter is added to the exhausted culture to measure the amount of oxygen consumed by the microorganisms. The determination of biochemical oxygen demand (BOD) of the sample is determined in as little as 20 minutes. An apparatus is provided for determining BOD comprising a magnetic stirrer, an aerating instrument, a dissolved oxygen/temperature sensor, tubing pumps and a quick biochemical oxygen demand (QBOD) bottle. The BOD may be automatically calculated using the apparatus.
