Changing climate, especially water content(WC) and CO2 (CD) concentration could be effect on the growth of soybean and seed yield. So we evaluated the effects of WC and CD on the physiological characteristics of newly developed soy cultivars in growth chamber. Ten soy cultivars evaluated in three [CO2] levels (CD1, 350; CD2, 500; CD3, 700ppm) and three water content (WC1: 30%, WC2: 40, WC3: 50%) in the pot in growth chamber. Increased [CO2] from 350 to 500 and 500 to 700ppm enhanced crop growth parameters greatly and grain yield, however, grown in CD3 enhanced plant height increasing speed, and shortened growing duration, however, they were grow very weakly and it resulted in lodging problem. High soil water content (WC3) hampered growth and yield of soybean in three CD treatments and the degree was lower in CD1 and CD2 than CD3. In this results we can conclude increasing [CO2] in Korean peninsular might be decrease lodging resistance, especially high moisture content, so, plant breeders and physiologists need to develop improved lodging resistance cultivars under high water content and high CO2 content.

[ ] 핵종이 함유된 IRN-150 혼상 폐수지로부터 이온의 제거 및 제거된 핵종의 기체로의 전환 특성을 고찰하였다. 비방사성 이온이 흡착되어 있는 IRN-150 혼합수지로부터 이온의 탈착용액내로의 분리 및 기체로의 전환 특성을 용액의 농도 변화에 따라 평가하였으며, 탈착용액으로는 를 사용하였고, 비교 평가를 위하여 NaOH, , HCl를 이용한 기체로의 전환 특성을 분석하였다. 아울러 월성 원자력발전소에 저장중인 실제 폐수지를 이용하여 탈착용액을 이용한 폐수지내 핵종의 기체화 특성을 평가하였고, 탈착후 잔류용액내 존재하는 감마핵종을 분석하였다.
