Recently, the demand for the damper-frame system has increased due to earthquake damage. And related researches are increasing in response while the researches considering the various design parameters such as strength and stiffness ratios between the damper and frame are insufficient. Therefore, in this study, propose for design characteristics value of the damper-frame system by setting the parameters related to strength and stiffness ratios between two systems and prediction formula through nonlinear dynamic analysis.

Recently, the demand for the seismic retrofit to existing buildings increased due to earthquake damage. And related researches are increasing in response while the researches considering the various design parameters such as strength and stiffness ratio between the existing structures and retrofit system are insufficient. Therefore, in this study, existing structure and reinforcing frame for damper are designed having different natural periods each other by setting the parameters related to strength and stiffness ratio between two systems and are analyzed by nonlinear dynamic analysis.

말차, 오룡차, 홍차 및 보이차로 제조한 음료가 Cd에 중독된 SD계 흰쥐의 해독에 미치는 영향을 조사하였다. 관능검사 결과 일반 물 추출물에 비하여 색상, 향, 맛에 대한 기호도가 현저하게 향상되었으며, 종합적 기호도는 오룡차 음료가 4.18점, 홍차음료가 4.14점으로 말차음료나 보이차 음료의 점에 비하여 높았다. SD계 흰쥐를 정상군 (NC), Cd 대조군(Cd-Co), Cd투여 말차음료 15% 급여군 (Cd-Gt), Cd투여 오룡차음료 1
