Abstract: The present disclosure relates to a method of preparing a polymer, which includes: adding an alkyl-substituted aromatic vinyl-based monomer and a vinyl cyanide-based monomer to a reactor and initiating polymerization; and performing polymerization while continuously adding an alkyl-substituted aromatic vinyl-based monomer and a multifunctional initiator to the reactor, wherein the continuous addition of the alkyl-substituted aromatic vinyl-based monomer and the multifunctional initiator is initiated when a polymerization conversion rate is 10 to 30%, and the continuous addition of the alkyl-substituted aromatic vinyl-based monomer and the multifunctional initiator is terminated when a polymerization conversion rate is 70 to 80%.

Abstract: The present invention relates to a Lactobacillus lactis CKDB001 strain, and a composition for the prevention or treatment of non-alcoholic fatty liver comprising same. When the composition of the present invention is ingested, the composition has the effect of ameliorating high-fat diet-induced fatty cirrhosis and inflammations caused thereby, and thus the composition of the present invention can be effectively used as a preparation for ameliorating or treating non-alcoholic fatty cirrhosis and steatohepatitis.

Abstract: Disclosed are a pharmaceutical composition for preventing or treating a respiratory disease, and health functional food, a food composition, and a quasi-drug composition for preventing and ameliorating a respiratory disease, each including, as active ingredients, a Lactobacillus plantarum KC3 strain and a Leonurus japonicus extract. The composition including the Lactobacillus plantarum KC3 strain (Accession No: KCTC13375BP) and the Leonurus japonicus extract as active ingredients according to an aspect has a defense effect against respiratory damage caused by air pollutants such as fine dust and can inhibit expression of IL-17A, TNF-?, and CXCL-1, thereby being able to effectively treat or prevent a respiratory disease including chronic obstructive pulmonary disease (COPD).

Abstract: The present disclosure relates to a composition for ameliorating immune disorders and preventing or treating respiratory inflammatory diseases, the composition including, as an active ingredient, new lactic acid bacteria from Lactobacillus plantarum KC3 (also referred to as “CKDB-KC3”).

Abstract: A method of preparing a supported metallocene catalyst capable of more effectively preparing a polyolefin which may be preferably used for blow molding, etc., because its molecular weight distribution is such that polymer elasticity is increased to improve swell, is provided.
