이 연구에서는 원자력발전소 주변 환경 방사선이 생태에 미치는 영향을 감시할 수 있는 생물학적 지표로서 야생 등줄쥐의 활용 가능성을 평가하였다. 국내 5지 역을 선정하여 10월에 한정하여 등줄쥐를 채집하였는데, 농경지에서 산중턱에 이르기까지 폭 넓게 서식하였다. 채집한 쥐들에 대하여 황갈색 피모와 검은색 등줄무늬를 관찰하였는데, 외부형태 특성 가운데 몸통의 길이, 꼬리의 길, 귀의 길이를 계측한 결과, 등줄쥐의 분류기준과 일치하였다. 아울러, 간장내 효소형을 분석한 결과 국내에 서식하는 대부분의 등줄쥐가 Apodemus agrarius라는 것을 알 수 있었다. 또한, 야외에서 생포한 등줄쥐를 암수 한 마리씩 동거시키고 생산된 새끼가 5주령에 도달하였을때 방사선을 조사하고, ICR 마우스를 비교로 생존율과 적혈구내 미소핵 출현빈도를 분석한 결과, 반치사 선량은 5와 7.9Gy였다. 이 연구결과로 야생 등줄쥐가 원자력 발전소 주변 수준의 방사선이 인간생환에 미치는 영향을 판단할 수 있는 생물학적 인 지표로서 잠재적 활용성이 높다는 것을 알 수 있었다.

본 연구는 유아의 일상생활과 연계된 다큐멘터리를 활용한 환경교육활동이 유아의 환경감수성 및 환경보전지식에 미치는 영향을 알아보는데 그 목적이 있다. 연구대상은 D시에 소재한 유치원에 재원중인 만 5세 유아 36 명(실험집단 18명, 통제집단 18명)이며, 실험처치는 매주 1회씩 회당 2-3일에 걸쳐 11주간 이루어졌다. 실험집단에는 3개 공영방송에서 제작한 다큐멘터리 중 연구자가 유아의 일상생활과 유아환경교육의 영역이 반영된 다큐멘터리 11편과 연계하여 구성한 환경교육활동을 적용하였으며, 통제집단에는 누리과정의 일반적인 환경교육활동을 적용하였다. 유아의 환경감수성을 알아보기 위하여 조부경, 지옥정, 김경철, 정아림(2016)이 재구성한 검사도구를 사용하였고, 환경보전지식을 측정하기 위해 최명하(2012)가 수정·보완한 검사도구를 사용하였다. 그 결과 유아의 일상생활과 연계된 다큐멘터리를 활용한 환경교육활동이 유아의 환경감수성 및 환경보전지식에 긍정적인 영향을 미치는 것으로 나타났으며, 이는 유아의 환경감수성 및 환경보전지식을 증진시키는 의미 있는 접근방안이 될 수 있음을 시사한다.

The goal of this study was to examine the effects of urban forest program on environmental sensitivity, academic stress and academic achievement in high school students. Thirty high school students were assigned to an experimental group, which participated in weekly urban forest program, and thirty students to a control group. As a result, the experimental group showed the significant improvement in environmental sensitivity and academic achievement, and higher environmental sensitivity along with lower academic stress. The results suggest that, as urban forest program enhances environmental sensitivity of students, their academic stress was reduced, and the program may influence academic achievement positively.

This research was composed over a period of 10 times and was performed to be conducted in an environmental education class for 4 months from September to December of 2008 by selecting 32 experimental group students and 32 control group students from OO Middle School in the Busan area. An environmental education program utilizing IIM(independent investigation method) was composed by selecting a theme for environmental education among the environmental curriculum in middle schools. The results of analyzing the effects which influence environmental sensitivity and environment-friendly behaviors after applying the environmental education program utilizing IIM are as follows. First, it was revealed that the environmental education program utilizing IIM is more effective among experimental group students than control group students in regards to environment-friendly sensitivity. Second, it was revealed that the environmental education program utilizing IIM is more effective among experimental group students than control group students in regards to environment-friendly behaviors. Third, it was seen that even students responded very favorably toward environmental education program utilizing IIM.

Today, environmental pollution and destruction due to the industrialization of our modern society have been the global issues. Although now we can lead affluent lives through science technologies and economic development, these environmental problems have resulted in striking the harmonious balance between human beings and nature and threatened human lives with abnormal weather caused by the global warming, destruction of the ozone layer, and El Nino phenomenon, acid rain, decrease in species diversity, movement of hazardous materials, and harmful waste increase. We are aware of the importance of environmental education, but in reality, it seems impossible to implement appropriate environmental education on account of our educational climate which exclusively focuses on the entrance examination. However, environmental education is the most ultimate solution for those problems in that only when students understand our environment fully and grow habits to protect it through environmental education, the present environmental problems can be solved and more serious problems that can be resulted in the future can possibly be prevented. Thus, this study has examined the effect of using image media in the environment subject on students’ environmental sensitivity. According to the results, it was shown that it had positive effects on ‘sensitivity of environment’, ‘attitudes towards environment’, and ‘environmental affinitive behaviors’.
