Abstract: An apparatus for measuring bio-signals is provided. According to an example embodiment, the apparatus for measuring bio-signals includes: a light source configured to emit light onto an object; an image sensor including: a pixel array configured to detect the light emitted by the light source and reacted by the object and a pixel binning unit configured to bin data of the light, detected by the pixel array, by using at least two different binning sizes; and a processor configured to acquire a plurality of bio-signals respectively based on data of the at least two different binning sizes, which are output from the image sensor.

Abstract: Provided is an electronic apparatus of performing communication through a communication system implemented using a plurality of relays, the electronic apparatus including a beam shaping module that shapes a beam for transmitting and receiving data, an antenna aligned to transmit and receive a beam shaped by the beam shaping module, a transceiver for transmitting and receiving the data in relation to another electronic apparatus through the antenna, and at least one processor configured to determine a beam hopping pattern between the plurality of relays, change a relay, which is used to transmit and receive data in relation to the another electronic apparatus sharing the beam hopping pattern, from a first relay included in the plurality of relays to a second relay included in the plurality of relays based on the beam hopping pattern, and control at least one of the antenna, the beam shaping module and the transceiver to transmit and receive data through the second relay.

Abstract: Disclosed is a communication method of an electronic device. Specifically, the communication method of the electronic device may include receiving, from a plurality of relay devices, a plurality of signals of a downlink associated with a signal of an uplink transmitted by a first electronic device, restoring a plurality of pieces of data with the plurality of signals being processed, and identifying reception data corresponding to transmission data included in the signal with the plurality of pieces of data being multiplexed based on a set multiplexing.

Abstract: The present invention relates to a plant-based COVID-19 variant recombinant spike protein expression vector, and a recombinant protein using the expression vector, wherein a plant expression system is used such that the recombinant protein does not have the disadvantages of animal-derived recombinant proteins and exhibits an excellent SARS coronavirus 2 prevention and treatment effect, and thus can be effectively utilized as a safe composition for preventing and treating COVID-19.

Abstract: The present invention relates to an antibody for identifying phosphospecific reactions of threonine at position 1010 in the amino acid sequence of non-SMC condensin II complex subunit G2 (NCAPG2), and a use thereof. It has been identified that: an antibody for identifying whether threonine at position 1010 in the amino acid sequence of NCAPG2 is phosphorylated, according to the present invention, has high selectivity and avidity with respect to pT1010 of NCAPG2; the reactivity thereof to pT1010 of NCAPG2 is inhibited in cancer cells treated with inhibitors of kinases for regulating cellular mitosis phase, such as CDK1, PLK1, Mps1, and aurora kinase; and detection of the antibody is far higher in tumor tissues than non-tumor tissues of a cancer patient through immunohistochemical staining.

Abstract: The present invention relates to polyether amino acid ester compounds, preparation method and their use as hydrocarbon fuel additives.

Abstract: An ester compound is prepared with a greatly improved efficiency by reacting a liquid alcohol with a liquid organic acid at a temperature of about 30 to 70.degree. C. in the presence of a lipase without adding any solvent. In particular, short chain acids and alcohols are reacted with lipase from candida antarctica immobilized on an acrylic resin.

Abstract: A plastic composition superior in both biodegradability and physical properties, comprises a matrix resin which is a blend of polyethylene and a biodegradable aliphatic polyester, starch, a coupling agent, a radical initiator, a starch plasticizer, a starch destructurizing agent and an autooxidizing agent, wherein the starch chemically binds to the matrix resin.

Abstract: A thermoplastic elastomeric composition, which comprises liquid 1,2-polybutadiene, EPDM rubber, a polyolefin resin, a curative system consisting of phenolic resin and peroxide, and a co-curing agent, the 1,2-polybutadiene and EPDM rubber being at least partially cured, shows well-balanced various properties including physical properties, elasticity and thermal resistance in addition to being superior in oil resistance at high temperatures and processability.
