Primary cardiac osteosarcoma is extremely rare. We herein report a case involving a 31-year-old woman with a 2-week history of left upper trunk pain and hemoptysis. She was diagnosed with primary cardiac osteosarcoma with pulmonary vein obstruction and successfully treated via surgical resection and chemotherapy. (Korean J Med 2015,89:233-237)

본 증례의 경우 1개월 전 심근경색으로 치료를 받았던 환자로, 혈변으로 내원하여 후천성 제5인자 결핍증을 진단받았으며, 제5인자 억제 인자 형성의 원인으로는 이전 입원시 시행한 경피적 관상동맥 중재술이 의심된다. 환자는 신선냉동혈장 수혈에 반응하지 않았지만, 스테로이드 치료에 좋은 반응을 보였으며 현재 스테로이드 투약을 중단한 채 경과 관찰 중 재발 소견은 확인되지 않고 있다. 이에 경피적 관상동맥 중재술 이후 발생한 후천성 제5인자 결핍증의 첫 번째 증례로 보고하는 바이다. Acquired factor V deficiency is extremely rare. Here we report the case of an 88-year-old female patient who presented with hematochezia 1 month after undergoing percutaneous coronary intervention. Her laboratory results showed an extremely prolonged prothrombin time and an activated partial thromboplastin time, but neither improved after fresh frozen plasma transfusion. She was finally diagnosed with acquired factor V deficiency and successfully treated with an immunosuppressant. (Korean J Med 2017;92:480-483)

BIM-related policies are steadily being introduced in the construction industry. The 2030 architectural BIM activation roadmap includes BIM automation technology and intends to apply it to the design system certification system. Design certification evaluation is conducted with 2D drawings, and additional research is needed because certification evaluation using BIM technology is insufficient. In this study, a study for design certification automation application was conducted by analyzing the design certification system and BIM data. Design certification system analysis, cases and research trends were investigated, and BF certification was carried out first in various systems. Evaluable areas were classified using BIM data, and applicability was reviewed using IFC, which is BIM information. Based on BIM, a system for reviewing and evaluating items within the evaluation range was partially implemented. Through this study, the efficiency of work can be improved and reliable evaluation can be obtained by automating additional work for certification in the design certification stage.

Among the problems in the construction industry, BIM technology, which can supplement accuracy and efficiency, is recognized as an important technology in the fourth industry and has already been proven to have advantages in many respects. On the other hand, the utilization rate is relatively low for the number of design certification cases due to the improvement of user convenience and the mandatory system. In this study, a study for data classification was conducted to establish BIM-based evaluation automation of Barrier Free (BF) among design certification systems. Detailed analysis of the evaluation items was conducted and classified based on space and geometric objects, and made BIM data classification table according to the result of analysis and classification. This study suggests BF certification data classification table to enable automation of design certification system evaluation, which can be used as a data classification plan through similar methods of other design certification systems.
