Abstract With advances in deep learning and natural language processing (NLP), the analysis of medical texts is becoming increasingly important. Nonetheless, despite importance texts, no research on Korean medical-specific models has been conducted. The text highly difficult to analyze because agglutinative characteristics language, as well complex terminologies domain. To solve this problem, we collected a corpus used it train models. In paper, present model based NLP. was trained using...

In a 12-lead electrocardiogram (ECG) examination, the ECG signals often have low-quality data problems due to high-frequency noise caused by muscles and low-frequency body movement, breathing. These cause delays in examination results increase medical costs. For this reason, solving missing can provide patients with improved services, reducing work-loss The purpose of study is develop signal restoration model for each 12 solve mechanical operator errors during examinations. study, 13,862...

Objectives: Electrocardiography (ECG)-based diagnosis by experts cannot maintain uniform quality because individual differences may occur. Previous public databases can be used for clinical studies, but there is no common standard that would allow to combined. For this reason, it difficult conduct research derives results combining databases. Recent commercial ECG machines offer diagnoses similar those of a physician. Therefore, the purpose study was construct standardized database using...
