Such compositions are useful in producing polyurethanes. The compositions can generally be stored without substantial loss of activity. https://scholar.dgist.ac.kr/handle/20.500.11750/58704 https://scholar.dgist.ac.kr/handle/20.500.11750/57010 Title: METHOD AND APPARATUS FOR MONITORING UNMANNED GROUND VEHICLE Author(s): 은용순; 나규진 https://scholar.dgist.ac.kr/handle/20.500.11750/57010 https://scholar.dgist.ac.kr/handle/20.500.11750/57003 Title: 입출력 데이터 기반 제어 시스템 외란 추정 방법 및 장치 Author(s): 이주승; 은용순; 이재호 https://scholar.dgist.ac.kr/handle/20.500.11750/57003 https://scholar.dgist.ac.kr/handle/20.500.11750/56684 Title: 시스템 상태 추정 장치 및 방법 Author(s): 은용순; 정예찬 https://scholar.dgist.ac.kr/handle/20.500.11750/56684
