데이터 증강은 데이터 불균형 문제를 해결하기 위해 일반화 성능을 향상시킨다. 이는 과적합 문제를 해결하고 정확도를 높이는 데 도움을 준다. 과적합을 해결하기 위해서 본 논문에서는 분할 마스크 라벨링을 자동화하여 효율성을 높이고, RoI를 활용한 분할 Copy-Paste 데이터 증강 기법을 제안한다. 본 논문의 제안 방법을 적용한 결과 YOLOv8 모델에서 기존의 분할, 박스 Copy-Paste 데이터 증강 기법과 비교해서 쓰러진 사람 객체에 대한 정확도가 10.2% 증가함으로써 제안한 방법이 일반화 성능을 높이는 데 효과가 있음을 확인하였다.

22년 동안 다양한 환자들을 만나고 또 다양한 피부과적 문제를 살피며 많은 사람들이 피부에 대한 잘못된 상식을 가지고 있다는 걸 알게 되었다는 피부과 전문의 안건영, 그가 말하는 올바른 피부상식, 그 가운데서도 '안티에이징'에 대한 이야기를 정리해보았다.

Child Psychiatric consultations on 92 patients hospitalized at the Seoul National Childrens Hospistal were analyzed retrospectively. The main referral sources were Pedictrics(77.2%), Neurosurgery(8.91%) and Orthopedics(3.96%) Consultation rate was 0.81% for the Hospital, 1.41% for Department of Pediatrics, 3.54% for Neurosurgery and 0.3% for the other department were made for the differential diagnosis raher than for the treatment or intervention. The diagnosis of referred patients were somatoform disorder(25%), organic mental disorder(18.5%), developmental disorder(14.1), conduct disorder(6.5%), anxiety disorder(6.5%).

For the design and maintenance of highways and road structures, the statistical data are needed for the vehicle, especially heavy truck crossing. So far, static weighing has been used but it needs fixed station, crews, and it takes a lot of time. Also truck mix and headway distances cannot be obtained. Bridge Weigh-In-Motion system uses the bridge as a weighing scale and collects the axle weights, axle distances. vehicle types and etc. without stopping or slowing down the vehicle. In this study, for the first time in the country, BWIM system is applied on steel I-girder bridge and its applicability is examined. Also data collected in this system is analyzed to get truck traffic characteristics including average daily truck traffic, weight distribution, typical truck configuration and overweight truck status. The results are compared with other data from weighing station and highway toll gates.
