수면 무호흡 탐지를 위한 통계적 특징 기반 이진 분류 모델과 다중 분류 모델 성능 비교

박흥진,오정환,강윤정 대한기계학회 2025 대한기계학회논문집B Vol.49 No.6

수면 무호흡은 수면 중 호흡이 반복적으로 중단되는 현상으로 혈중 산소 포화도가 감소되고 다양한 건강 문제를 야기한다. 본 연구는 수면 상태에서 수면 무호흡을 탐지하는 이진분류와 정상 호흡, 저호흡, 폐쇄성 수면 무호흡을 다중 분류하는 계층적 2단계 방법을 제안한다. Airflow, PTAF, snore 센서 데이터를 10초로 분할하고 시간/주파수 영역에서 통계적 특징을 추출한다. 기계학습 모델의 입력으로는 Fisher score, 상관관계, 특징 중요도 방법을 사용하여 선별된 특징들을 이용한다. 이진 분류는 XGBoost와 Random Forest의 정확도 평균이 0.95 이상으로 신뢰할 수 있는 결과를 보였다. 계층적 2단계의 다중 분류에서도 Random Forest와 XGBoost의 평균 정확도가 0.88로 우수했고, 클래스 별 정확도가 단일 단계 분류 방식보다 향상되었다. 제안한 방법은 수면 무호흡을 정확하게 탐지하고, 저호흡과 폐쇄성 수면 무호흡으로 세분화하여 임상 적용 가능성을 보였다. Sleep apnea is characterized by repeated interruptions of breathing during sleep, leading to various health problems. We propose a binary classification method for detecting sleep apnea and a hierarchical two-stage classification method for multi-class classification into normal breathing, hypopnea, and obstructive sleep apnea. Sensor data from Airflow, PTAF, and Snore are segmented into 10-second intervals, and statistical features are extracted from time and frequency domains. Features selected using Fisher score, correlation, and feature importance methods are used as inputs for machine learning models. The binary classification showed reliable results with an average accuracy of over 0.95 using XGBoost and Random Forest. In the hierarchical two stage multi-class classification, both Random Forest and XGBoost achieved an average accuracy of 0.88, with per-class accuracy surpassing that of the single-stage multi-class approach. The proposed method accurately detects sleep apnea, further distinguishing between hypopnea and obstructive sleep apnea, including its potential for clinical application.

This study was to investigate the impact of environment characteristics on perceived value and visit intention in franchise coffee shops. And, the study was to examine the mediating role of perceived value in the relationship between environment characteristics and visit intention. The data were collected from 212 coffee shop users and analyzed with SPSS and AMOS.. The findings are as follows. First, price, service, and atmosphere have a significant effect on the defined hedonic value but menu does not . Second, price and service have a significant effect on utilitarian value but menu and atmosphere do not. Finally, both hedonic value and utilitarian value have a significant effect on visit intention.

Purpose - In align with the increasing competition in both online and offline franchise markets caused by the increasing impact of social networking service, entrepreneurial passion(EP) of the franchise owners has crucial impact on the stakeholders. This study proposed the customer among stakeholders has the critical influence firm’s success and examined the structural relationship between entrepreneurial passion(EP) and trust, identification, and loyalty from the customer’s perspective. Research design, data, and methodology - This study examines the structural relationship between entrepreneurial passion(EP), trust, identification, and loyalty from the customer’s perspective. More specifically, the EP were measured using three sub-dimensions such as EP-inventing(Perceived passion for inventing), EP-founding(Perceived passion for foundting), and EP-developing(Perceived passion for developing). In order to verify the research purposes, research model and hypotheses were developed. All constructs were measured with multiple items developed and tested in the previous studies. Each item was measured on a 7 point Likert-scale anchored by ‘1 = strongly disagree, 7 = strongly agree’. The data were collected from 449 franchise consumers through online survey and were analyzed using SPSS 21.0 and Smart PLS 3.0. statistical program. Result - The results of this study are as follows. First, EP-inventing and EP-developing have significant impacts on corporate trust. Second, EP-founding does not have significant impact on corporate trust. Third, EP-inventing and EP-founding have significant impacts on consumer identification. Fourth, EP-developing does not have impact on identification directly, but does indirectly through corporate trust as a mediator. Fifth, corporate trust and identification have significant impacts on loyalty. Conclusions - This indicates that the foodservice franchise CEOs should continuously develop new menus and service to fulfill customer needs. EP-inventing of the food franchise CEOs may enhance customer trust for higher quality of product or service, and EP-developing can also be a driving force for customer trust as it embeds belief in customers that the franchise is sustainably developing. Also, food franchise CEOs should first clarify the support process for the existing brands before developing new ones. Customers tend to lead the trend by using brands that satisfy new trends in the foodservice franchise market, and it could have identification with the trend-setting franchise. Customers do not accept if a company is different from their personal image or norms. So the franchise CEOs must create identification with customers by building corporate trust. Corporate trust influences consumer behavior and emotion, thus the franchises need to secure trust by improving product or service continuously.

A study on the optimal drying condition by a vacuum drying oven was done using shredded tobacco lamina and commercial cigarettes ('This'). Changes in the mass of the experimental material were monitored for about 50 hrs at 6 different temperatures (5$0^{\circ}C$~10$0^{\circ}C$, 1$0^{\circ}C$ stepwise) while continuously operating a vacuum pump. After 30 hrs, small amount of samples from each material were taken sequentially to monitor changes in moisture content using a Karl-Fischer method (Metrohm KF 701 Titrino). Absolute moisture contents calculated from the measurements indicated an ideal data distribution could be obtained by drying at temperatures between 7$0^{\circ}C$~8$0^{\circ}C$. Results from cigarette products which contains humectant and tobacco lamina without it were compared.

The design of a courseware software on Internet is becoming important. This paper deals the design and implementation of a courseware using WWW. The experimental system introduces students various features of a local community. With the strong point of Interest, for example, accessibility, the system allows the learners to study the content anywhere and anytime only if they can connect to Internet. And students can choose what to study freely using hypermedia nature of world wide web. The courseware software is experimented with the sample group of elementary school students.
