적정기술을 활용한 초등학교 녹색기술교육프로그램의 적용 및 효과
최지연 한국실과교육연구학회 2013 실과교육연구 Vol.19 No.4
이 연구는 최지연(2012b)의 초등학교 실과와 융합된 적정기술을 적용한 녹색기술교육프로그램을 학교 현장에 적용하고 효과를 검증하기 위한 목적에서 수행되었다. 연구의 목적을 이루기 위해 첫째, 설문조사의 정량적 분석을 통한 프로그램의 효과 검증, 둘째, 자유기술형 응답, 면담의 정성적 분석을 통한 효과 검증이라는 연구 내용을 설정하였다. 프로그램 적용의 효과는 선행연구와 전문가 검토를 거쳐 구안된 설문조사 문항지와 인터뷰 가이드를 통해 확보한 자료를 정량적, 정성적 방법으로 분석하여 검증하였다. 이 연구의 결과는 다음과 같다. 첫째, 초등학교 실과와 융합된 적정기술을 적용한 녹색기술교육 프로그램을 충북의 W 초등학교 6학년 남, 녀학생 24명을 대상으로 7주 동안 적용하여 효과를 검증하였다. 둘째, 설문조사를 통한 정량적 분석 결과 적정기술에 대한 인식과 지속가능한 삶에 관한 태도에서 학생들은 대부분 긍정적인 변화를 보였다. 셋째, 자유기술형 응답과 면담의 정성적 분석 결과 적정기술에 대한 이해와 생각, 지속가능한 삶에 관련된 태도 등에서 학생들은 긍정적인 변화를 보였다. 이를 통해 적정기술을 적용한 녹색기술교육 프로그램이 단기간의 교육 프로그램이라는 한계에도 불구하고 적정기술에 관한 인식과 지속가능한 삶에 대한 태도에서 긍정적인 효과를 가져왔음을 알 수 있었다. The purpose of this study was to applicate and verify green technology education program fused with practical arts education at the elementary level. To achieve the purpose of this research, two research tasks were established. First, to verify applied program through questionnaire in quantitative research methods. Second, to verify applied program through self descriptive replies and interviews in qualitative research methods. The effects of program application were verified by data from questionnaire and interviews that were designed through an expert’s verification. The results of this study were as follows. First, green technology education program fused with elementary practical arts was applied and verified in 24 students of 6th grade of W elementary school in Chungbuk province. Second, as the results of quantitative analysis by questionnaire showed that positive change of students occurred in most parts of categories likes recognition, thinking, attitude. Third, as the results of qualitative analysis by self descriptive replies and interviews presented that positive change of students occurred in understanding and thinking of appropriate technology and attitude of sustainable life. As a result, despite of limit that green technology education programs with appropriate technology were not long times, it presented that the programs made positive effects in recognition of appropriate technology and attitude of sustainable life.
Splenogonadal Fusion: A Case Report
최지연,한석,김영주 대한영상의학회 2011 대한영상의학회지 Vol.65 No.6
Splenogonadal fusion is a rare congenital anomaly characaterized as the fusion of the spleen and a gonad. The first report of this anomaly was in 1883 and only 160 cases have been reported to date. As far as we know, this is the first reported case of splenogonadal fusion in this country.

This study examined the beneficial effects of the n-butanol fraction and rutin extracted from tartary buckwheat (TB) on learning and memory deficits in a mouse model of amyloid β (Aβ)-induced Alzheimer’s disease (AD). Learning and memory were assessed using the T-maze, object recognition, and Morris water maze tests. Animals administered Aβ showed impaired cognition and memory, which were alleviated by oral administration of an n-butanol fraction and rutin extracted from TB. Similarly, Aβ-induced increases in nitric oxide formation and lipid peroxidation in the brain, liver, and kidneys were attenuated by treatment with n-butanol fraction and rutin from TB in addition to antioxidant effects observed in control (nonAβ-treated) animals. The results of the present study suggest that the n-butanol fraction and rutin extracted from TB are protective against and have possible therapeutic applications for the treatment of AD.
