Abstract: A method of an aerial vehicle for urban air mobility may include: reporting, to a first base station, a measurement result for neighboring base stations including a second base station; receiving, from the first base station and as a processing result based on the measurement result, an indication of a failure of a handover to the second base station; requesting, to a control station, first location information indicating a first location to move according to the failure of the handover; receiving the first location information from the control station; and moving according to the received first location information.

Abstract: The present disclosure relates to a serum exosomal SF3B4 marker composition for diagnosing early stage hepatocellular carcinoma for noninvasive in vitro diagnosis, wherein, by analyzing an expression level of SF3B4 in plasma proteins as well as expression of SF3B4 in exosomes present in sera of hepatocellular carcinoma patients, the possibility as the most suitable liquid biopsy marker was identified, and a new noninvasive biomarker with high diagnostic accuracy in early stage hepatocellular carcinoma for which no reliable biomarker exists at this present was discovered. As such, by using exosomes to identify cancer cell genomes and proteomes without biopsy, the exosomes are highly applicable in the future as a diagnostic biomarker that is useful in a disease group with a high risk in the biopsy such as hepatocellular carcinoma.

Abstract: The present invention provides an energy storage system comprising: a battery module formed by connecting a plurality of hollow secondary batteries that have hollow tubes therein, respectively; a safety module that includes a cooling/heating unit that stores a cooling/heating medium therein and an extinguishing unit that stores an extinguishing medium therein; a first circulation channel that interconnects the battery module and the safety module to circulate the cooling/heating medium or the extinguishing medium between the battery module and the safety module; and a battery management system that measures the temperature and pressure of the battery module and opens the cooling/heating unit or the extinguishing unit to supply the cooling/heating medium or the extinguishing medium to the first circulation channel when the temperature and pressure of the battery module reaches a preset value.

Abstract: A hollow core secondary battery, including: an outer container having a hollow with open opposite ends and containing an electrode assembly therein; an inner container having a hollow with open opposite ends and being inserted in a central portion of the electrode assembly; and a vent unit provided on or in the inner container, wherein, when an internal pressure of the battery is increased above a predetermined value, the vent unit is ruptured to allow for gas and heat to be exhausted to an outside through the hollow of the inner container.

Abstract: A hollow core secondary battery, including: an electrode assembly comprising a pair of electrode plates and a separator disposed between the pair of electrode plates; an outer container in which the electrode assembly is received; an inner container inserted into a central portion of the electrode assembly, the inner container being hollow; a first terminal assembly assembled at a top portion of the outer container, the first terminal assembly into which a top end portion of the inner container is inserted; and a second terminal assembly assembled at a bottom portion of the outer container, the second terminal assembly having a central portion into which a bottom end portion of the inner container is inserted.

Abstract: Disclosed are an electrochemical device and a method for manufacturing the same. The electrochemical device includes an electrode assembly that is formed in such a manner that a first electrode, a separator, and a second electrode are wound in the form of a jelly-roll shape, and includes a hollow portion in a center thereof, a first tap plate that is installed on an upper surface of the electrode assembly to be electrically connected to the first electrode, and includes a first through-hole corresponding to the hollow portion in a center thereof, and a second tap plate that is installed on a lower surface of the electrode assembly to be electrically connected to the second electrode, and includes a second through-hole corresponding to the hollow portion in a center thereof.
