    摘要： Disclosed are a sandwich panel capable of being advantageously applied to a body wearable device, and a method of manufacturing the same. The sandwich panel includes: a core; and face sheets attached to both surfaces of the core, wherein the face sheet is made of a two-dimensional auxetic material. The core has a neutral surface in accordance with bending moment and is made of a porous material. The face sheet is made of metal, polymer, ceramic, or a composite material, and has higher density, strength, and rigidity than the core. The method includes: processing face sheets; and attaching the face sheets to both surfaces of a core, wherein the face sheet is processed to have a two-dimensional auxetic structure.

    摘要： An ALD or digital CVD apparatus and method for microparticles are proposed. The apparatus and the method use an impact, which is caused by the pulsed introduction of a precursor or a purging gas to be introduced into a reactor, without additional vibration or rotation of the reactor, so as to inhibit the agglomeration of particles to be applied to a surface and enable dispersion to be maximized, thereby enabling each particle to be uniformly applied, and simultaneously preventing the loss, in the reactor during processing, of powder to be coated without an additional separate filter or filler. A deposition reactor has a structure in which at least two overlapping reactors are provided. A reactant or a purging gas directly flows into an inner reactor in which a chemical reaction occurs. A purging step is simultaneously carried out in inner and outer reactors.

    摘要： The present invention relates to a composition for viral RNA extraction and a viral RNA extraction method using the same, wherein various contaminants (e.g., fungi, bacteria, pollens, etc.) can be effectively removed from samples and thus the diagnosis of sample-derived viruses can be attained more sensitively, and more cheap reagents compared with existing compositions for RNA extraction are used and thus the scales of diagnosis tests of disease-mediated viruses and various monitoring programs can be further enlarged, thereby contributing to public health.

    摘要： The present invention relates to a flagellin fusion proteins and a use thereof and, more specifically, to a fusion protein comprising flagellin, a fragment thereof; or a variant thereof; and an immunoglobulin Fc region and use in which a toll-like receptor 5 (TLR5) stimulating activity thereof is used. The fusion protein provided by the present invention has remarkably excellent toll-like receptor 5 (TLR5) pathway activation ability compared to wild-type flagellin, a fragment thereof, or a variant thereof, and therefore can be greatly utilized to develop a therapeutic agent and/or a vaccine adjuvant for a disease that can be prevented, improved, or treated through activation of the TLR5 pathway.

    摘要： Provided are a deep learning-based beamforming communication system and method, wherein in an indoor environment using millimeter wave communication, in response to reference signals transmitted from a base station to at least one user terminal, reference signal received power and location information for each user terminal location are received from each user terminal and a fingerprint DB is constructed, and from the constructed fingerprint data, a user model is constructed on the basis of reference signal received power for each user terminal location and a blockage model is constructed on the basis of reference signal received power according to each blockage located between the base station and the user terminal. Location information and data traffic are received from the at least one user terminal, a beam index of the user terminal corresponding to the received data traffic is derived from a deep neural network, and a communication channel between the base station and a user is formed with the derived beam index, whereby reliability and a data transfer rate are improved in an indoor communication environment.
