Abstract: A leakage current detection circuit includes: a mirror circuit configured to copy a leakage current flowing through a node and generate a copy current in a copy node; an oscillation circuit including a charge storage unit, the oscillation circuit being connected to the copy node, charged with the copy current, and configured to generate an oscillation signal by charging and discharging the charge storage unit; and a calculation circuit configured to calculate an amount of the leakage current based on the oscillation signal.

Abstract: Disclosed are wood preforming devices for manufacturing a crash pad for a vehicle including a real wood sheet. A wood preforming device for manufacturing a crash pad for a vehicle includes a real wood sheet includes a lower press mold comprising a debossed portion provided on a portion on which a product is formed, and a support portion configured to support an upper press mold, in response to the lower press mold and the upper press mold pressing each other, the support portion having a protrusion for fixing a real wood sheet, the upper press mold having an embossed portion corresponding to the debossed portion of the lower press mold, and a movable core provided on the debossed portion of the lower press mold and being configured to guide the real wood sheet by moving upward from the debossed portion, in response to the upper press mold moving downward.

Abstract: Disclosed are a method and apparatus for reusing wastewater. The method for reusing wastewater disclosed herein includes: generating a mixed wastewater by mixing multiple types of wastewater (S20); performing a first purification by passing the mixed wastewater through a flocculation-sedimentation unit (S40); performing a second purification by passing an effluent of the flocculation-sedimentation unit through a membrane bioreactor (MBR) (S60); performing a third purification by passing an effluent of the MBR through a reverse-osmosis membrane unit (S80); and reusing an effluent of the reverse-osmosis membrane unit as cooling water or industrial water (S100).

Abstract: A language correction system, a method therefor, and a language correction model learning method of the system are disclosed. The system comprises a correction model learning unit and a language correction unit. The correction model learning unit performs machine learning on a plurality of data sets consisting of ungrammatical sentence data and error-free grammatical sentence data respectively corresponding to the ungrammatical sentence data, so as to generate a correction mode for detecting grammatical sentence data corresponding to ungrammatical sentence data to be corrected. The language correction unit generates, for a sentence to be corrected, a corresponding corrected sentence by using the correction model generated by the correction model learning unit, and displays and outputs the corrected parts together with the generated corrected sentence.

Abstract: The present invention relates to an apparatus for circulating balls. An embodiment of the present invention includes: a circulation path for circulating balls and fluid, the circulation path comprising a cooling water tube of a heat exchange unit; a pump arranged in the circulation path for pumping the balls and fluid; and a counter for counting the time and the number of the balls in relation to the circulation of the balls.

Abstract: Disclosed is a cosmetic composition having a double-shell type nano-structure. More particularly, the nano-structure of the cosmetic composition includes: a water-soluble bioactive ingredient core; a core shell containing poly(ethyleneglycol)-poly(caprolactone)-poly(ethyleneglycol) (PE-PCL-PEG) triblock copolymer in order to include the bioactive ingredient core therein; and an outer shell containing phospholipids or derivatives thereof in order to enclose the core shell therein. Such a cosmetic composition improves stability of active components which are prone to oxidation, light degradation, heat degradation, etc., is formed in a nanoparticle size which in turn shows high transdermal absorption and is very useful to prepare a cosmetic composition stably encapsulating various bioactive ingredients with anti-wrinkle effects, whitening effects, and so forth.
