Abstract: Disclosed are a carbon dioxide absorbent composition in which an N-alkylaminoalkanol; a polyhydroxyamine-based compound; and ethylenediamine and/or diethylenetriamine are mixed, a method for preparing the same, and a method and an apparatus for carbon dioxide absorption/separation using the same. Since the carbon dioxide absorbent according to the present disclosure has superior carbon dioxide absorption capacity and remarkably lower absorbent recycling temperature as compared to the existing absorbents such as monoethanolamine, etc., total energy consumption in the capturing process can be reduced greatly. In addition, since carbon dioxide is recovered at low recycling temperature, contamination by water or absorbent vapor may be prevented.

Abstract: Provided are a method and apparatus for detecting an event-related potential (ERP), the method including: detecting an R-peak signal by detecting an electrocardiogram (ECG) signal of a subject via an ECG sensor; inducing an evoked potential to the subject by presenting an ERP stimulus to the subject at a certain period on basis of the R-peak signal; and detecting an electroencephalogram (EEG) signal of the subject exposed to the ERP stimulus by using an EEG sensor, and extracting an ERP signal from the EEG signal, wherein intermixture of a heart-rate evoked potential (HEP) of the subject with the ERP signal is inhibited by removing the ERP stimulus being presented to the subject during the certain period, after a latency by a certain time from a point in time the R-peak occurs.
