Purpose: The purpose of this study is to assess the influence of the amount of walking exercise on metabolic syndrome and metabolism-related factors for the elderly with sedentary life using KNHNES data. Method: The data were obtained from the KNHNES Ⅶ conducted in 2016~2108. The subjects, a total of 4,288 elderly aged 65 years and older, were classified into two groups based on habitual sedentary life time and three groups based on total walking exercise amount. The dta processor for this study was used as a percentage and standard error (SE) or mean (M) of all measured values, used chi-square test, generalized linear model, and logistic regression analysis. Results: The results of this study are as follows. 1) The body mass index and waist circumference of the sedentary life group were significantly higher than those of tehnormal group (p<.001). 2) The prevalence of metabolic syndrome was significantly higher in the sedentary lief group than in the normal group (p<.001). 3) The difference of metabolism-related factors between the walking exercise amount groups in sedentary life was significantly higher in height, weight, total calorie intake (p<.001), and HDL-C (p<.01). 4) The prevalence of metabolic syndrome in the walking exercise groups was significant (p<.05). Conclusion: In summary, the findings in this study confirm that people with a sedentary life are more likely to have metabolic syndrome. The amount of high-intensity walking exercise and the amount of moderate-intensity walking exercise in a sedentary life can prevent metabolic syndrome.

Development of soybean cultivars with great nodulation and high nitrogen fixation activity, derived mostly from mutagenesis, may decrease inputs of chemical fertilizer nitrogen into the soil-plant system. Soybean seeds (cv. Jangyupkong, Hwanggeumkong, and Geomjungkong 1) were treated with three different levels of EMS (ethyl methanesulfonate) concentration(30, 50, and 70mM). Increasing the doses of EMS resulted in decreased field emergence rate of seeds, whereas it did not increase M$_2$ mutation frequencies. This indicated that the most efficient concentration of EMS was 30mM for generating mutants. Extensive mutagenesis of Sinpaldalkong 2 with 30mM EMS was undertaken to isolate soybean mutants with greater nodulation. Approximately 8, 200 M$_2$ families were screened for greater nodulation on 5 mM nitrate after inoculation with Bradyrhizobium japonicum strain YCK213-KFCC-10728. Mutant SS-2 nodulated more than the wild type. Comparison of supernodulation between SS-2 and two nts mutants(nts 1007 and nts 1116) revealed that SS-2 showed the supernodulation character at an earlier growth stage than the two nts mutants. Further studies should be needed to characterize the difference in timing of nodulation between SS-2 and nts mutants.

이 연구는 과학 교육과정 중 천문관련 단원의 내용과 천문과학관의 전시내용을 비교 분석하여 천문과학관이 교육과정의 내용과 목표를 얼마나 잘 반영하고 있는지 알아보는데 목적이 있다. 연구 대상은 국내 천문과학관 5곳으로 천문과학관 프로그램 평가도구를 사용하여 프로그램 내용을 평가하고 프로그램 형태를 조사하여 분석하였다. 이 때 사용된 평가도구는 교육부(1997)에서 고시한 과학교육과정 내용과 교육과정 평가원(2000)에서 제시한 성취기준 및 평가기준을 근거로 고안하였다. 이 연구의 결과를 요약하면 다음과 같다. 천문과학관에서는 과학 교육과정 내용 중 천문관련 학습요소를 대부분 반영하고 있었다. 이는 천문과학관이 비형식 교육 기관으로서 학교 과학 교육과 비교적 잘 연계되고 있음을 보여준다. 교육과정 반영비율은 5학년이 가장 높으며, 전시 형태는 패널 형태가 가장 많았다. 평가점수는 반영비율에 비하여 낮았는데 이는 향후 천문과학관의 프로그램을 선정함에 있어 과학 교육과정을 더 충실히 반영하여야 함을 알 수 있다. The purpose of this study is to investigate how much the programs of astronomy museums reflect the contents and objectives of current science curriculums. To attain the aim, comparison and analysis on the museum programs and science curriculum have been made. Five domestic astronomy museums have been selected. The contents and forms of their programs have been studied and appreciated by assessment instruments for astronomy museum programs. The assessment instruments were devised in consideration of both the science curriculums of the Ministry of Education(1997) and the achievement and evaluation criteria of the Korea Institute of Curriculum and Evaluation. The findings of this study are summarized as follows: The astronomy museums reflect most of the learning elements of science curricula concerning astronomy. These results indicate that the astronomy museum as an informal education institute is comparatively well connected to science education. The 5th grade science curriculum reflected mostly on the museum programs, and too many of the astronomy museum programs were in forms of panel exhibition. Science curricula fared well but they failed to reflect the curricular objectives, which resulted m relatively low assessment scores. It is suggested that the findings of this study can be a foundation and act as guidance for selecting and developing astronomy museum programs which include the contents of the science curriculums more substantially.

콩과작물에 있어서 뿌리혹의 질소고정능력 향상은 화학비료의 저투입에 의한 농업환경 오염 경감 및 생산비 감소등 재배적인 면에서 유리하다. 최근 본 연구진은 신팔달콩 2호에서 EMS (ethylmethane sulfonate)를 처리하여 다량 뿌리혹이 형성되는 돌연변이체를 개발하였다. 다량 뿌리혹 형성 (hypernodulation) 콩 계통과 원품종과의 접목실험 결과에 의하면, 기존에 호주, 미국, 일본 등지에 개발된 변이체와 유사한 뿌리혹 형성기작을 가지고 있는 것으로 추측되며, 이는 원품종의 지상부에서 생성되는 뿌리혹 형성 억제물질이 다량 뿌리혹 형성 계통에는 존재하지 않는 것으로 생각되었다. 한편 다량 뿌리혹 형성 콩 계통은 질소고정 능력이 높으나, 지상부 생육이 적어서 개체당 수량은 원품종에 비하여 낮았다. 따라서, 다량 뿌리혹 형성 계통의 농업적 이용은 낮은 수준의 질소를 시비하여 생산비를 경감하고, 동시에 밀식율 유도하여 원품종과 대등한 단위면적당 수량을 확보하는 차원에서 가능할 것으로 생각되어진다. 한편, 다량 뿌리혹 형성 관련 유전인자를 구명하기 위하여 SSR 마아커를 이용한 다량 뿌리혹 계통과 원품종과의 DNA 변이를 조사한 결과, 대부분의 마아커에 대한 변이가 인정되지 않았다. 따라서, 다량 뿌리혹 콩 계통은 단순 유전인자 혹은 한 개의 DNA base pair의 변화로 유기된 돌연변이에 의하여 유래 된 것으로 생각된다.
