Abstract: The present disclosure provides: a compound of a specific chemical structure, having excellent activity with respect to BTK degradation; or a pharmaceutically acceptable salt thereof. The present disclosure also provides a composition comprising the compound or pharmaceutically acceptable salts thereof. The present disclosure also provides are pharmaceutical use for treating or preventing BTK-associated diseases (for example, autoimmune diseases or cancer) of the compound, the salt thereof, and the composition comprising same according to the present disclosure. The present disclosure also provides a method for treating or preventing BTK-associated diseases (for example, autoimmune diseases or cancer), comprising administering, to a subject requiring treatment, an effective amount of the compound, the salt thereof, or the composition comprising same according to the present disclosure.

Abstract: Disclosed is a method for preparing bio-oil, which can be used as bio heavy fuel oil and bio marine oil, from a fatty acid with high acid value.

Abstract: An Internet-of-things (IoT)-based impact pattern analysis system for a smart security window includes: an ultra-small IoT device attached to a security window and detecting an impact; a station processing a signal obtained from the ultra-small IoT device and analyzing an impact pattern; and a user terminal outputting information related to the impact pattern through an interface. The station controller processes 3-axis acceleration data to extract a feature vector and determines an impact pattern by applying a learning model. According to the embodiment of the present disclosure, by automatically determining whether an intrusion occurs by analyzing impact patterns according to various conditions and circumstances, malfunction based on an impact other than an intrusion may be reduced and an unnecessary alarm may be prevented.

Abstract: Disclosed is a method for preparing fatty acid alkyl ester for bio-diesel fuels by reacting a raw material containing fat with water to prepare fatty acid, and then reacting the prepared fatty acid with alcohol. The method for preparing fatty acid alkyl ester for bio-diesel fuels includes the steps of: preparing fatty acid and glycerin by an hydrolysis reaction of a raw material containing fat and water at the temperature of 200 to 280° C. and the pressure of 30 to 80 bar; carrying out a phase separation of the fatty acid and the glycerin; and carrying out an esterification reaction of the separated fatty acid and alcohol at the temperature of 200 to 350° C. and the pressure of atmospheric pressure to 35 bar.
