Abstract: Provided are a biodegradable aliphatic-aromatic polyester copolymer having excellent hydrolysis resistance and high viscosity which has a carboxyl end group (CEG) content of 15 mg KOH/g or less, a ratio (Mz/Mn) of a z-average molecular weight (Mz) to a number average molecular weight (Mn) of 3 to 15, and a melt index (MI) of 5 g/10 min or less as measured under conditions of a temperature of 190° C. and a load of 2.16 kg in accordance with ASTM D 1238. A method of preparing a biodegradable aliphatic-aromatic polyester copolymer is provided, including adding a chain extender and an anti-hydrolysis agent to an aliphatic-aromatic polyester pre-copolymer over time, whereby a significant viscosity rise and improvement of hydrolysis resistance may be implemented simultaneously.

Abstract: A transformer translation system for deep learning using triple sentence pair is designed to do both a rough translation and a revision of rough translations, and utilize reinforcement learning using a deep learning facility to produce data of refined translations. And this transformer translation system can translate literary works, webtoons, subtitles, and the like, which can be commercially distributed or exported to overseas markets, taking into account feelings, nuances, atmosphere, jargons, tones of voice, writers' intentions, context, etc. so that consumers or readers can enjoy not mere plain translations but refined, high-quality translations. Furthermore, this transformer translation system for deep learning using triple sentence pair may automatically produce the final translations, which can be commercially viable, continuously for an indefinite time without limit.

Abstract: A battery management system (BMS) may include a battery, a relay configured to electrically connect and disconnect the battery for supplying a voltage (an electric power) to an electric load to and from the electric load, the electric load configured to receive the voltage (the electric power) from the battery, to compare the received voltage (the electric power) with a reference value and to output a wakeup signal according to the compared result, when the relay is electrically connected, and a controller configured to wake up by the wakeup signal, to monitor a state of the battery and to control a state of the relay. It is possible to prevent overdischarge and overcharge of the battery by monitoring the battery through the electric load in a state in which a vehicle is turned off and switching the BSM to a wakeup state only if necessary.

Abstract: Disclosed herein is a technique for determining degradation of a high-voltage battery of a vehicle. More specifically, variations in charge capacity with respect to a predetermined variation in voltage of a high-voltage battery that is currently being slowly charged are obtained depending on degradation degrees of the high-voltage battery. A vehicle equipped with a high-voltage battery having a specification identical to those of the high-voltage battery is used to acquire a charge capacity and a voltage of the high-voltage battery that is currently being slowly charged. A variation in charge capacity with respect to the predetermined variation in voltage is calculated from the charge capacity and the voltage. The variation in charge capacity with respect to the predetermined variation in voltage is compared with the variations in charge capacity with respect to the predetermined variation in voltage depending on the degradation degrees, thus determining a relevant degradation degree.

Abstract: An apparatus and method for diagnosing degradation of a high voltage battery of a vehicle are provided. The method includes calculating an average charging power of a slow charger during a setting interval on slow charging for an electric vehicle and calculating a correction factor based on the average charging power. The method also includes calculating a degree of degradation of the battery based on the average charging power and calculating a final degree of degradation by reflecting the correction factor to the degree of degradation.

Abstract: A method of checking deterioration of a battery includes: measuring a power input by a charger in a specific SOC range, when the battery is being charged; and determining a current deterioration rate of the battery by applying the measured power to a function having, as an input, a power input in the specific SOC range and, as an output, a deterioration rate of the battery.
