    다국어 초록 (Multilingual Abstract) kakao i 다국어 번역

    The purpose of this study is to investigate the feasibility of remote-Photoplethysmography (rPPG) for stress detection in construction workers. rPPG signals were collected from six participants performing arithmetic and Stroop tasks under controlled conditions. After preprocessing and applying a sliding window, 67 time, frequency, and nonlinear features were extracted. Five machine learning classifiers were evaluated, among which Quadratic Discriminant Analysis (QDA) achieved the highest accuracy of 83%. These findings demonstrate the potential of rPPG as a contactless method for stress monitoring and its applicability to construction safety management.
