Abstract: An information set extraction method based on parallel decoding for extracting m information sets (where m is an arbitrary integer greater than or equal to 1) including n attributes (where n is an arbitrary integer greater than or equal to 1) from a document, the information set extraction method including: receiving, by a system comprising a neural network model of a sequence-to-sequence (seq2seq) structure, a document; and determining m information sets through a plurality of times of decoding. The determining of m information sets through a plurality of times of decoding includes determining first column information having m first attributes through decoding; and determining i-th column information having m i-th attributes based on at least one of the first to (i?1)-th column information through decoding (where i is an arbitrary integer such that 2<=i<=n).

Abstract: Disclosed is a composition for improving resistance to drought and osmotic stress containing a compound represented by Formula 1 as an active ingredient, the composition containing the compound represented by Formula 1 being able to minimize inhibition of the growth of crops while improving resistance to drought and osmotic stress.

Abstract: The present invention relates to a method for treating contaminated soil. A method for treating contaminated soil according to the present invention comprises: a flushing step of inserting a spraying rod including a nozzle into soil to spray a flushing liquid or an oxidizing liquid thereto; a first collection step of collecting floating material from the soil after the flushing step; a first phase separation step of separating the floating material collected in the first collection step into a liquid phase material and a solid phase material; a heating step of inserting a heating member into the solid fraction separated in the phase separation step to heat the solid fraction; a second collection step of collecting steam generated by the heating step; and a pyrolysis step of separating a gas phase material from the floating material from the floating material separated in the second collection step and performing heat treatment.

Abstract: The present invention relates to Ofree, a novel wheat cultivar produced by crossing Keumkang wheat and Olgeuru wheat, in which low-molecular-weight glutenin subunit (LMW-GS) alleles located at the Glu-B3 loci (major cause of gluten intolerance) and ?-5 gliadin genes (major cause of wheat-dependent exercise-induced anaphylaxis (WDEIA)) have been deleted; a method of developing a new wheat cultivar using Ofree; wheat flour produced from Ofree; a method of producing a processed food using the wheat flour; and a processed food produced by the aforementioned production method. It is expected that Ofree provided in the present invention can be widely used for the production of processed foods capable of preventing the onset of celiac disease caused by gluten intolerance and the onset of WDEIA.

Abstract: There is provided a method and system for recycling by-products containing large amounts of useful components and discharged in the form of dust and sludge from a coal-based molten iron making process to reuse the by-products in a reduced iron agglomeration process. The system includes: a fluidized reduction furnace reducing fine iron ore; a reduced iron tank connected to the fluidized reduction furnace through a reduced iron discharge pipe for storing the reduced iron and supplying the reduced iron in an agglomeration system; an agglomeration system agglomerating the reduced iron transferred from the reduced iron tank; and a transfer unit transferring compactions of by-products discharged from a molten iron making process through a by-product supply pipe. The compactions of the by-products are supplied to at least one selected from the group consisting of the fluidized reduction furnace, the reduced iron supply pipe, and the reduced iron tank.

Abstract: Disclosed herein is a centering control type drill system for offshore structures. The centering control type drill system is installed to be elevated in a derrick for offshore drilling and rotates a drill string. The centering control type drill system includes a motor providing rotational force for offshore drilling, a gear box unit placed below the motor and increasing the rotational force of the motor, a main rotary shaft placed below the gear box unit and rotating the drill string; an intermediate bracket provided to the gear box unit, a dolly bracket disposed to be elevated in the derrick, a first dolly arm retractably coupled between the dolly bracket and the intermediate bracket by a hinge, a second dolly arm retractably coupled between the dolly bracket and the intermediate bracket by a hinge, and a cylinder rotating the second dolly arm about the hinge.

Abstract: Disclosed herein is a derrick lift system of an offshore structure. The derrick system can improve drilling workability by enabling safe and easy height adjustment of a derrick using an adjustment unit, and can improve structural stability by lowering the center of gravity of the derrick through the height adjustment of the derrick, as occasion demands.
