Abstract: Provided are an apparatus for manufacturing a textile grid with increased adhesion and a method thereof capable of integrating the textile grid with a concrete structure by increasing the adhesion of the textile grid when the concrete structure is built, repaired, or reinforced, increasing structural safety and durability of the concrete structure, increasing a working speed by coating a surface of the textile grid with an abrasive material powder that is a surface coating material in an automatic series of processes immediately after the textile grid is manufactured, and increasing coating performance by automatically inspecting and adjusting the amount of the coating material applied to the surface of the textile grid using a camera.

Abstract: An example electronic device includes a housing; a touchscreen display; a microphone; at least one speaker; a button disposed on a portion of the housing or set to be displayed on the touchscreen display; a wireless communication circuit; a processor; and a memory. When a user interface is not displayed on the touchscreen display, the electronic device enables a user to receive a user input through the button, receives user speech through the microphone, and then provides data on the user speech to an external server. An instruction for performing a task is received from the server. When the user interface is displayed on the touchscreen display, the electronic device enables the user to receive the user input through the button, receives user speech through the microphone, and then provides data on the user speech to the external server.

Abstract: The present disclosure relates to a method and device for providing questions for learning. According to the present disclosure, a method by which a server provides questions for question includes step a of displaying learning content on a first region of a screen displayed on a terminal of a learner; step b of fixedly displaying an AI object on a second region of the screen; step c of determining whether a learning progress of the learner satisfies a predetermined object activation condition; and step d of displaying an AI message corresponding to the object activation condition on a third region of the screen adjacent to the AI object while the AI object is activated, when the learning progress satisfies the object activation condition. According to the present disclosure, a user interface may be adaptively changed according to a question solving situation of a learner, thereby inducing continuous learning of a user.

Abstract: Disclosed is a method for purifying an ester compound, including: adding a base to a resultant reaction mixture comprising a plasticizer of an ester compound synthesized by an esterification reaction of an acid and an alcohol so as to neutralize unreacted acids; applying steam to the resultant reaction mixture which has been neutralized; adding diatomite to the resultant reaction mixture which has been steamed, prior to filtration through a filter, and then subjecting the resultant reaction mixture to which the diatomite has been added to a primary filtration; and adding an activated white clay to the resultant reaction mixture, and then subjecting the resultant reaction mixture which has been primarily filtrated to a secondary filtration through a filter.

Abstract: Disclosed is a method of purifying terephthalate-based ester compounds, including: adding a base to a resultant reaction mixture comprising terephthalate-based ester compounds synthesized by esterification of terephthalic acid and alcohol so as to neutralize unreacted acids; applying steam to the resultant reaction mixture which has been neutralized; adding a filter aid to the resultant reaction mixture which has been steamed prior to filtration through a filter; and filtering through a filter the resultant reaction mixture to which the filter aid has been added, wherein the filter aid comprises diatomite particles having an average particle size of 50 ?m to 90 ?m.

Abstract: Provided is a method for preparing monosilane, more particularly a method for economically preparing monosilane, which is useful for the composition of a thin semiconductor structure and multipurpose high-purity polycrystalline silicon, by preparing monosilane with high purity and high yield using trialkoxysilane.

Abstract: The present invention relates to a method for preparing SiH(OR3)-type trialkoxysilane (wherein, R is a C1-C3 methyl, ethyl, propyl or isopropyl group), and more specifically, the method comprises the steps of: preventing the oxidation of a silicon surface by pulverizing raw silicon material in a solvent environment without contact with the air so that the initial induction period of the direct synthesis of trialkoxysilane is dramatically reduced; and removing impurities from a reaction environment by continuously selecting a part of the solvent through a membrane filter provided in a reactor body.

Abstract: A system for automatically eliminating a paper jam in an electrophotographic device may be initiated by removing and re-inserting a paper cassette subsequent to the occurrence of the paper jam. If the paper cassette is removed and inserted, a paper jam eliminating mode is implemented to eliminate the paper jam.
