- Prof. Seoyeon Dong identifies the effect of daily stress on oxygen saturation in brain blood flow
Professor Seoyeon Dong and Student Soyeon Park of the Department of IT Engineering in the Division of ICT Convergence Engineering at Sookmyung Women’s University successfully revealed the effect of daily stress on the change of oxygen saturation in blood flow in the prefrontal cortex using functional near-infrared spectroscopy. The research results were published in IEEE Access, the SCI journal within the top 30% of the JCR ranking, on November 4 (Wed).

The paper was titled “Effects of Daily Stress in Mental State Classification,” and was published with Soyeon Park, a student in the 4th year in the Department of IT Engineering, as the lead author.
In the existing psychological stress studies, it was common to find stress-specific biosignal features using a protocol that induces stress in a subject, and classify when there is stress and when there is no stress using that feature.
However, the research team pointed out that using such approach is difficult to verify whether a stress-free state is actually a state when there are no stress inducing factors, and proposed a classification model that considers the level of individual daily stress rather than experimentally induced stress. As a result, it was found that the state classification performance can be improved up to 24% compared to the existing method.
This research result was based on the research paper led by Soyeon Park under the guidance of Professor Seoyeon Dong for the past year and a half. Following the oral thesis presentation at EMBC 2020, a renowned international society in the field of biomedical engineering in February, this is an extraordinary research accomplishment as an undergraduate student.
Student Soyeon Park said, “It was a rewarding experience because I was able to conduct research as an undergraduate student and get meaningful results. Based on this research, I would like to challenge more applied researches in various bio-signal-related fields. I also would like to sincerely thank Professor Seoyeon Dong for the guidance.”
