비대면 휘트니스 MR 플랫폼 개발을 활용한 운동 수행 효과에 관한 연구
김준우,Kim, Jun-woo 국제문화기술진흥원 2021 문화기술의 융합 Vol.7 No.3
This study was carried out to overcome the problems of the existing fitness business and to build a fitness system that can meet the increased demand in the Corona situation. As a platform technology for non-face-to-face fitness edutainment service, it is a next-generation fitness exercise device that can use various body parts and synchronize network-type information. By synchronizing the exercise information of the fitness equipment, it was composed of learning contents through MR-based avatars. A quantified result was derived from examining the applicability of the customized evaluation system through momentum analysis with A.I analysis applying the LSTM-based algorithm according to the cumulative exercise effect of the user. It is a motion capture and 3D visualization fitness program for the application of systematic exercise techniques through academic experts, and it is judged that it will contribute to the improvement of the user's fitness knowledge and exercise ability.

본 논문에서는 요부 초음파 영상을 이용하여 재활 치료 분야에 보조적으로 활용할 수 있는 다열근 두께의 자동 측정 방법을 제안한다. 초기 요부 초음파 영상에서 불필요한 잡음을 제거하고, Ends-in Search Stretching 기법을 적용하여 피하지방 영역과 근육 영역의 명암 대비를 강조한다. 그리고 형태학적 특징과 위치 정보를 이용하여 피하지방 영역과 근육 및 등뼈 경계 영역을 추출한 후, 피하지방 영역과 근육 및 등뼈 경계 영역의 하단 윤곽선을 추출한다. 그리고 초기 전처리 과정을 거친 영상에 최소 명암도와 최대 명암도를 이용한 Ends-in Search Stretching 기법을 적용하여 등뼈 후보 영역을 추출하고, 형태학적 특징과 위치 정보를 이용하여 최종 등뼈 영역을 추출한다. 추출된 근육과 등뼈의 경계 윤곽선에 Valley Search 기법을 적용하여 근육 영역을 측정하는데 기준이 되는 등뼈 위치를 탐색하여 피하지방 영역의 하단 경계와 근육 측정에 기준이 되는 등뼈 사이의 거리를 측정한다. 제안된 방법을 요부 초음파 영상에 적용하여 요부 근육의 두께를 측정한 결과, 재활 치료 분야에서 효과적으로 적용할 수 있는 자료를 제시할 수 있음을 물리 치료사를 통하여 확인할 수 있었다.

We retrospectively analysed CT findings of 47 cystic brain lesions of 44 patients, in which operation, biopsy or follow-up study was needed for their final diagnosis. RESULTS : 1. The etologic diseases of cystic brain lesions were 15 cases of brain abscess, 9 cases of astrocytoma, 5 cases of glioblastoma multiforme, 3 cases of meningioma, 5 cases of craniopharyngioma, 1 case of hemangioblastoma, 2 cases of dermoid cyst and 4 cases of metastasis. 2. We aalyses the cystic lesions in view of thir number, location, shape, perifocal edema, mass efect, wall and its thickness, evenness and characteristics of their inner and outer surfaces, mural nodule, calcification and contrast enhancement. a. 13.3% of brain abscess and 75% fo metastases were muliple in number, but the remainder showed single lesion. b. The shape of cystic lesions were round or ovoid in 68%, lobulated in 8.5% and irregular in 23.5%, and no demonstrable difference of shape were noticed in different disease. c. In br in abcess, the wall of cystic lesions tend to be thin, even and smooth in inner surface, but the outer surfaces were equally smooth or irregular. d. Mural nodules were found in nearly half of the cases of astrocytoma, glioblastoma multiforme, metastasis and hemangioblastoma, but the brain abscess and dermoid cyst contained no mural nodule. e. Meningiomas werefound to be attached to dura mater and showed thickening of the inner table of adjacent skull or of the falx. f. The presence of preceding infectious disease may be helpful in the diagnosis of brain abscess, but in 20% there were no deonstrable preceding infection. g. Lung cancer was confirmed as primary site in two of the cystic metastatic disease, but other 2 cases showed no demonstrable primary malignancy.
