Abstract: Disclosed is an ionomer for a high-temperature polymer electrolyte membrane fuel cell, which includes a phosphorus (P)-containing functional group having proton conductivity and partially contains fluorine in the main chain thereof.

Abstract: Disclosed are novel compounds of Chemical Formula 1, optical isomers of the compounds, and pharmaceutically acceptable salts of the compounds or the optical isomers. The compounds, isomers, and salts exhibit excellent activity as GLP-1 receptor agonists. In particular, they, as GLP-1 receptor agonists, exhibit excellent glucose tolerance, thus having a great potential to be used as therapeutic agents for metabolic diseases. Moreover, they exhibit excellent pharmacological safety for cardiovascular systems.

Abstract: Provided are a method of detecting abnormal financial transactions and an apparatus thereof. The apparatus includes: a memory in which an abnormal transaction detection program is stored; and a processor configured to execute the program. Upon execution of the program, the processor performs a data preprocessing operation to acquired payment data, extracts at least one feature adaptively determined in advance from results of the preprocessing operation, and uses the extracted feature to determine whether the payment data correspond to an abnormal transaction through a machine learning algorithm adaptively determined in advance.

Abstract: An antibacterial puff for cosmetics in which an antibacterial agent is included in a foam composed of polyurethane and the like is disclosed. More particularly, an antibacterial puff reduces excessive consumption of a cosmetic material caused by absorption of a puff, which is a disadvantage of an existing puff, and includes an antibacterial material capable of suppressing proliferation of microorganisms.
