Disseminated peritoneal leiomyomatosis (DPL) is a very rare benign disease, characterized by multiple solid subperitoneal or peritoneal smooth muscle nodules in abdominopelvic cavity and malignant transformation is extremely rare. Also, uterine smooth muscle tumors of unknown malignant potential (STUMP) is a rare tumor, which is regarded as subclassification in uterine smooth muscle tumors between benign and malignant criteria. Pathogenesis of DPL is uncertain, but increasing evidence of iatrogenic cause including laparoscopic myomectomy has been reported. We report a case of a 28-year-old female with previous history of laparoscopic myomectomy diagnosed with DPL with atypical feature and concurrent uterine STUMP using computed tomography (CT) and magnetic resonance imaging (MRI), as well as present a review of the literature.

This study aims to develop a bodice and a jacket in 3D of the late 19th to early 20th based on the pattern drafting book of Gordon S. S., which contains body measurement method and pattern drafting system. The findings of this research are as follows. First, female tops of the late 19th to early 20th century are categorized as outer, jacket, vest, and bodice. Of these, this study highlights the jacket, which can be divided into 4 types: 4 kinds of basic jacket, 2 kinds of riding jacket, bolero jacket, and newmarket jacket. Second, by referring to Gordon’s pattern drafting system and book, a bodice was developed in 3D format based on the adherence to the following steps: analysis of the pattern drafting system, pattern drafting, 3D virtual simulation, 3D virtual fitting analysis, and the pattern correction. A bodice pattern corrected by 3D virtual clothing simulation results was proposed. Last, a basic sleeve and collar pattern for a basic jacket was drafted, which was followed by the correction and transformation of the bodice pattern. The jacket developed shows great fit except for the issues at the armhole line and shoulder, which were caused by the unique shape of the sleeves(big sleeve head) of the time. The study attempted to develop the past costumes in 3D, providing the basis for interdisciplinary research in the field of fashion history field and suggesting a new approach for the virtual restoration of costumes. Future studies should target to 3D virtual simulation in accordance to the 3D avatar pose in the developed virtual costume.
예측모형의 머신러닝 방법론과 통계학적 방법론의 비교: 영상의학 연구에서의 적용
Leeha Ryu,Kyunghwa Han 대한영상의학회 2022 대한영상의학회지 Vol.83 No.6
최근 영상의학 연구 분야에서 영상 인자를 포함한 임상 예측 모형의 수요가 증가하고 있고, 특히 라디오믹스 연구가 활발하게 이루어지면서 기존의 전통적인 회귀 모형뿐만 아니라 머신러닝을 사용하는 연구들이 많아지고 있다. 본 종설에서는 영상의학 분야에서 예측 모형 연구에 사용된 통계학적 방법과 머신 러닝 방법들을 조사하여 정리하고, 각 방법론에 대한 설명과 장단점을 살펴보고자 한다. 마지막으로 예측 모형 연구에서 분석 방법 선택에서의 고려사항을 정리해 보고자 한다.
