본 연구는 1992년 3월에서 1993년 5월까지 충북 청원군 강내면 다락리 야산에 서식하는 노랑턱멧새(Emberizo elegans) 집단을 대상으로 이루어졌다. 종 인식을 위한 의미있는 song 특징을 알아보기 위해 같은 과(요)에 속하는 붉은뺨멧새(Emberizo fucata)와 쑥새(Emberiza rustsca)의 'stereotyped song'을 분석하였다 또한 세력권을 형성한 5개체를 대상으로 song에 기초한 playback 실험을 통하여 종 인식 능력을 알아보았다. 스피커에 가장 가까이 날라온 거리와 이 거리에서 머문 시간을 측정한 결과 붉은뺨멧새의 song에는 반응이 없었으나 쑥새의 song에는 의미있는 반응을 보였다. 따라서 노랑턱멧새와 두 종에 대한 song 특징의 분석을 토대로 종간 인식의 가능성에 대하여 논의하였다.

This study was conducted to investigate whether attitudes and recognitions of middle and high school students regarding environmental concerns were improved after anuran call monitoring. It was a step toward monitoring local environmental changes with anuran calls. Three-striped pond frogs (Rana nigromaculata), Bullfrogs (R. catesbeiana), and Narrow-mouthed toads (Kaloula borealis) were surveyed to determine local abundance and distribution of them in 12 study sites using their advertising calls. A published booklet, which contains morphological, physiological, ecological, and acoustic information on amphibian species and methods of monitoring anuran calls were provided to monitoring students for identifying the three species. Pretest-posttest were conducted before and after monitoring from 10 April to 28 August in 2005 to determine how the monitoring students changed their attitudes on environmental issues, increased knowledges on amphibians, and improved the understanding on the cause and effect of declining amphibian populations. The amphibian monitoring program was effective to improve the students' attitudes towards conserving environments as well as the students' knowledge on general behavior and ecology of various amphibian species although their understanding about various environmental problems was not. In addition, the program increased the students' understanding on the problems of declining amphibian populations.

The importance of physical changes in volume due to changes in temperature has been known for more than a century by the petroleum industry. To examine whether there are any differences between the economic effect of automatic temperature compensation and that of installation cost. The results of the analysis show that there are no ineffective in automatic temperature compensation installation. Analysis showed the increase of price oil will impact negatively on the automatic temperature compensation, appropriate level of economic cost and economic benefit should be calculated for the policy implementation in the future's study.

Currently, biodiversity conservation is regarded as one of the most important environmental issues in the 21st century. However, The educational approaches on biodiversity conservation is not actively developed. This study was conducted to develop the educational program on biodiversity conservation related with endangered species conservation for improving elementary and middle school girl students' knowledge on biodiversity, inspiring the value and importance of biodiversity, and improving the attitude toward the conservation of biodiversity. Because the biodiversity loss of wetlands such as rice-fields, rivers, marshes has made the breeding population of Oriental White Stork(Ciconia boyciana) endangered in Korea, this subject was very effective for students to learn the cause and effect of biodiversity loss realistically. The education program was conducted to 68 local elementary and middle girl students from 2007 to 2009 and consists of three main activities such as feeding on storks in captivity, sampling living organisms in rice-fields, and designing the future stork living village. The results didn't show a positive effect on improving the knowledge on the biodiversity, but a positive effect on improving the attitude toward the conservation of biodiversity. And the number of taxa that students noticed in rice-fields has increased significantly. In conclusion, this educational program promoted students to concern about and take up a positive attitude on the biodiversity conservation issue.

The red-eared slider (Trachemys scripta elegans) is the one of the most popular pets, and the most commonly traded species in the world. It is designated as an ecosystem disturbance species that has been managed in South Korea. To date, no reports of natural or anthropogenic migration and spreading of T. s. elegans in South Korea are available. In the present study, we estimated the expected route and the movable path of one female T. s. elegans found in Namsan-myun, Gyeongsan-si, Gyeongsangbuk-do. Based on the movable path, the potential destination of the female turtle was estimated to be about 282 m and 468 m away. Therefore, the moving distance of the red-eared slider to the nearest water system will be at least 606 m and at most 792 m. Our results provide the first evidence about the natural migration and spreading of exotic turtles. This study can serve as a basis for the management and countermeasures against the introduced of T. s. elegans and other exotic species in South Korea.
