In this paper, features and efficiencies of the 3D engine are described which has been developed through the research of 3D real time rendering techniques. And an on-line shooting game “3D Fortress” which has been developed using this 3D engine with server technologies is introduced for the techniques and methodology applied in the process of development of the game as well as the features and discussions of its implementation.

체내 이식형 의료장치들은 개발과정에서 임상적용전 사체실험(preclinical cadaver fitting test)을 실시하게 된다. 이를 통해 기계장치의 크기와 모양 및 구조 등이 인체 해부구조에 적합한지를 평가하고, 체내 이식에 적합한 최적의 위치를 결정하며, 임상에 적용가능한 수술술기를 완성할 수 있다. 저자들은 고려대학교 해부연구위원회의 승인을 받은 총 12구의 사체를 이용하여 자체 개발한 한국형 인공심장(AnyHeart)의 인체적용의 해부학적 적합성을 평가하였다. 관찰목표는 서로 다른 가슴안 접근법(복장뼈정중절개술, 오른쪽 개흉술, 왼쪽 개흉술, 복장뼈횡절개술)에서 인공심장의 적절한 이식 위치, 유입로와 유출로의 확보 및 도관의 삽입 위치 등이었다. 연구 결과 한국형 인공심장의 인체적용의 해부학적 적합성은 뛰어났으며, 특히 새로운 수술기법인 오른쪽 개흉술을 통한 인공심장 이식술을 가능하게 하였다. 본 연구를 통해 향후 본격적인 임상 시도의 토대를 마련하였고, 체내 이식형 의료장치의 개발과정에서 해부학적 적합성 평가의 중요성을 확인하였다. Preclinical cadaver fitting study is paramount in the development of various implantable medical devices. It helps to evaluate the fitness of the size, shape, structure of the devices in the human anatomy, to locate the most optimal site for implantation, and to develope the clinically available surgical techniques. The purpose of this study was to observe the anatomical feasibility of Korean artificial heart (AnyHeart) in 12 human cadavers after obtaining the permission from the Korea University Anatomical Research Committee. The observation was focused on proper position of the artificial heart in various thoracic incisions (median sternotomy, right thoracotomy, left thoracotomy, transsternal incision), localization of inflow as well and outflow tract, cannulation sites, and so on. Results showed that Korean artificial heart had excellent anatomical feasibility in the human body and that a novel surgical technique of right thoracotomy approach was proved to be clinically applicable. Conclusively, the above results will provide the rationales of clinical trial and demonstrate the significance of human cadaver study in development of implantable medical devices.

Traumatic asphyxia is a clinical symptom complex characterized by craniofacial cyanosis, subconjunctival hemorrhage, and head and neck vascular engorgement due to sudden compressive injury on the thoracic cage. It is occasionally combined with mental deterioration, lung contusion, and edema. It is considered due to increased intrathoracic pressure in state of closed epiglottis. Recently, we had experienced three cases of traumatic asphyxia of which clinical courses were somewhat different. The first case developed by a compression between a elevator and the ground while the victim did not realized the accident happening, and the patient showed nonspecific facial edema and ecchymosis but mental deterioration and ultimate respiratory failure. The second case by a compression between cars, while the impending accident was noticed by the victim, showed full-blown asphyxia without mental or respiratory symptoms. The last case by forceful coughing and vomiting showed facial edema and ecchymosis without any other symptoms. Hospital course of all cases were uneventful. We believe that "fear response" or "closure of the epiglottis" might be an important mechanism on developing symptom of traumatic asphyxia.
