The purpose of this study was to investigate the influence of the energy campaign environmental education of 3rd graders in elementary school in Seoul. The students were divided into an experiment group and a control group. A reconstructed questionnaire through Kim(2005) and Lee(2005)'s test tool was used to survey the effects of applying the energy campaign environmental education program. The i-STATistics program was used to analyze the results. The major results of this study are as follows. First, the researcher was able to develop and apply teaching-learning model for energy campaign environmental education by extracting and recreating the energy education-related contents from the lower grades(1, 2, 3 grade) in 2007 elementary school curriculum. Second, this program had a positive effect on pro-environmental altitudes of elementary school students. Third, this program had a positive correlation among the 3 subdomains of cognitive, affective and behavioral. Fourth, according to qualitative analysis, the students appear to be more concerned in the overall environmental problems containing energy problem and showed a higher will to act while participating in the environmental education through energy campaign program. In conclusion, this program is more directly effective than lectures on energy following the curriculum to improve student's pro-environmental altitudes. Therefore, more intensive research on teaching and learning activities should be highly considered.

In this research, it is a basic study to investigate the population of birds using UAVs. The research area is Ardeidae species(ASP) habitat and has long-term monitoring. The purpose of the study is to compare the ASP populations which analyzed ground observational survey and UAVs imagery. We used DJI's Mavic pro and Phantom4 for this research. Before investigating the population of ASP, we measured the escape distance by the UAVs, and the escape distances of the two UAVs models were statistically significant. Such a result would be different in UAV size and rotor(rotary wing) noise. The population of ASP who analyzed the ground observation and UAVs imagery count differed greatly. In detail, the population(mean) on the ground observation was 174.9, and the UAVs was 247.1 ~ 249.9. As a result of analyzing the UAVs imagery, These results indicate that the lower the UAVs camera altitude, the higher the ASP population, and the lower the UAVs camera altitude, the higher the resolution of the images and the better the reading of the individual of ASP. And we confirmed analyzed images taken at various altitudes, the individuals of ASP was not statistically significant. This is because the resolution of the phantom was superior to that of mavic pro. Our research is fundamental compared to similar studies. However, long-term monitoring for ASP of South Korea's by ground observation is a barrier of the reliability of the monitoring result. We suggested how to use UAVs which can improve long-term monitoring for ASP habitat.
