    Abstract: Disclosed herein is an image preprocessing/analysis apparatus using machine learning-based artificial intelligence. The image preprocessing apparatus includes a computing system, and the computing system includes: a processor; a communication interface configured to receive an input image; and an artificial neural network configured to generate first and second preprocessing conditions through inference on the input image. The processor includes a first preprocessing module configured to generate a first preprocessed image and a second preprocessing module configured to generate a second preprocessed image. The processor is configured to control the first preprocessing module, the second preprocessing module, the artificial neural network, and the communication interface so that the first preprocessed image and the second preprocessed image are transferred to an image analysis module configured to perform image analysis on the input image based on the first preprocessed image and the second preprocessed image.

    Abstract: Disclosure relates to modified sulfur, preparation method thereof, preparation equipment thereof. The modified sulfur has spinnability or includes micro-structures such as fiber-, film- and network-like structure. The modified sulfur can be prepared by inducing polymerization with ultrasonic or ageing. The modified sulfur has various excellent features such as anticorrosiveness, waterproofing, strength, and fast drying and can control the features depending on its viscosity or polymerization degree. In addition due to the above features, the modified sulfur can be applied to anticorrosive or waterproofing material and can prepare anticorrosive or waterproofing material which has good workability, hardening, salt spray resistance, and weldability exceeding a certain level, and specially improved adhesiveness. Furthermore, when applying the modified sulfur to asphalt composition, gelation and depression are reduced, properties such as bending strength and tensile strength are improved, and it is possible to obtain asphalt composition with good working stability at RT.

    Abstract: A method for producing tetraalkoxysilane includes reacting a compound represented by Chemical Formula 1 below with an alkali metal at a molar ratio ranging from 1.0:1.0 to 1.0:1.1 and in the absence of a solvent to produce a basic catalyst represented by Chemical Formula 2 below; and mixing the basic catalyst represented by Chemical Formula 2, silicon metal, and an alcohol represented by Chemical Formula 3 below to produce tetraalkoxysilane:
    Chemical Formula 1 R1O(CHR2CH2O)n—H, Chemical Formula 2 R1O(CHR2CH2O)n-M, and Chemical Formula 3 R3OH, where M is alkali metal, R1 represents a C1-C5 linear hydrocarbon group or a C3-C5 branched hydrocarbon group, R2 represents H or a C1-C3 linear hydrocarbon group, R3 represents a C1-C2 alkyl group, and n is an integer of 2-3. Thus, it is possible to increase the proportion of the catalyst in the process, and to minimize production of impurities caused by solvent decomposition.
