Abstract: An apparatus and method for measuring air currents on the surface of a substrate, which can accurately measure the magnitude and direction of air currents on the surface of a wafer with wafer-type air current measurement sensors, are provided. The apparatus includes: a first air current measurement module measuring a magnitude of air currents on a surface of a first substrate, which is processed in accordance with a semiconductor manufacturing process; a second air current measurement module measuring a movement direction of the air currents; and a power module supplying power to the first and second air current measurement modules, wherein the first air current measurement module, the second air current measurement module, and the power module are mounted on a second substrate, which has the same shape as the first substrate.

Abstract: Disclosed herein are a catalyst for hydrocracking reaction of high molecular weight components in bio-oil, a method for preparing the same and a method for bio-oil upgrading using the same. The catalyst includes a zeolite carrier; and at least one metal selected from the group consisting of nickel (Ni), ruthenium (Ru) and cerium (Ce) supported on the carrier. The catalyst promotes the hydrocracking of high molecular weight compounds contained in the bio-oil, but also inhibits the polymerization reaction of the decomposed product, thereby more effectively enhancing the hydrocracking reaction of the bio-oil.

Abstract: Provided are a data processing method and apparatus for training a depth information estimation model. The data processing method for training a depth information estimation model, includes: logging image data collected from one or more cameras; transmitting the logged image data to a database; configuring training data, based on the image data of the database; and training a model, based on the training data.

Abstract: The present invention relates to a composition and method for treating or preventing white spot syndrome virus of arthropod. The present invention is based on using Artemisia japonica extract, and preferably, a mixture of Artemisia japonica extract and Saururus chinensis extract as effective agent. More preferably, the present invention provides a composition for treating or preventing white spot syndrome virus, comprising Artemisia japonica extract and Saururus chinensis extract which are coated by a polymer. The present invention also provides a method for treating or preventing white spot syndrome virus of arthropod, using Artemisia japonica extract and Saururus chinensis extract which are coated by a polymer.
