칼륨施用水準과 生育段階 및 草種에 따른 秋草의 生育과 칼륨 및 마그네슘함량의 差異를 알아보기 위해 두가지의 水총#我培實驗을 실시했다. 먼저 生育段階의 진행에 따른 收草의 收量 및 無機物含量의 變化를 未本科救草 3種類를 사용하여, 목초가 발아한 후 15日 부터 55日 까지 조사했는데 그 結果는 (1) 發穿後 25 日 경 목초의 生草收量 및 칼슐含 量이 빠르게 增加했으며 (2) 이탈리안 라이그라스에서 칼륨含量이 가장 높고 마그네슘含量이 낮았으며, 툴 페스큐

The current load combination criteria for design of nuclear power plant structures(NPP) are not based on the probability • based design concept but rely on the conventional design concept. ln this paper. a load combination criteria for design of NPP containment structures are proposed based on a FEM - based random vibration analysis. More accurate reliability analyses under various dynamic loads such as earthquake loads were made possible by incorporating the FEM and random vibration theory‘ which is different from the conventional reliability analysis method. ln this paper‘ the load factors for the design of NPP structures in Korea are pro∞sed by considering appropriate load combination criteria for design
