국내에서 LM 작물의 재배는 승인 된 바 없으나 식품용 및 사료용으로 LM 작물이 수입되고 있으며 LM 작물의 국내 수입량은 꾸준히 증가하고 있는 추세이다. 본 연구는 2014년 경기 지역의 LM 옥수수 유출여부를 모니터링 하기 위해 수행되었으며 채집된 의심시료는 단백질 검정 분석법과 중합효소 연쇄반응을 통해 분석하였다. 경기 지역의 항만, 운송로, 사료공장 및 축산농가 등 총 169개 지점을 조사하였고 총 44개의 LM 옥수수 의심시료를 채집하였다. 단백질 검정 분석법으로 4개의 양성반응 시료를 확인하였고 동일지점의 시료는 혼합하여 총 3개의 시료에 대해 프로모터 스크리닝과 이벤트 특이적 프라이머를 이용한 중합효소 연쇄반응을 실시하여 의심시료 모두 LM 옥수수로 확인하였다. 본 연구의 결과는 국내 자연환경에서 LM 옥수수의 유출 현황 파악과 자연 생태계로 LM 옥수수의 유출을 예방하기 위해 자연생태계 모니터링이 매우 중요하다는 것을 뒷받침한다.

The purpose of this study is to investigate children's liquid conservation concept according to their ages and task-situations in the water evaporation phenomenon. Thirty from each 4-, 6- and 8-year-old age groups (total of 90 subjects) were selected for this study. The subjects were recruited from two day-care centers, a kindergarten, and an elementary school, in Seoul. Statistical methods used for data analysis were frequencies, percentiles, means, standard deviations and repeated measures ANOVA. As a result, there was a significant difference in children's liquid conservation concept in the evaporation of water according to their ages and task-situations. 8-year-old children showed levels of cognition than 4- and 6-year-olds. Children showed higher levels of cognition in the task of drying than in the task of water level changes.

With the rapid development of urban suburbanization, a plenty of commercial operation of suburban environmental resource, the environment in suburb is more and more deteriorated. It also leads some passive effect on ecology, human, society and nature etc. At the same time, a serial of emergency rescue action has been implemented to decrease the deteriorating of suburban environment. For example, some important ecology nature reserves were built up; some compulsive protections have been put in practice for some key resource development region and gotten some good achievements. However, we still face the problem is that how to balance the contradiction between suburban environment resource development and conservation. It's necessary to introduce some western advantage management ideas, combined our actual situation, to find a way which is the most benefited to combine our country's suburb environment development and use.

The RapidEye satellite sensor has various spectral wavelength bands, and it can capture large areas with high temporal resolution. Therefore, it affords advantages in generating various types of thematic maps, including land cover maps. In this study, we applied a supervised classification scheme to generate high-resolution land cover maps using RapidEye images. To improve the classification accuracy, object-based classification was performed by adding brightness, yellowness, and greenness bands by Tasseled Cap Transformation (TCT) and Normalized Difference Water Index (NDWI) bands. It was experimentally confirmed that the classification results obtained by adding TCT and NDWI bands as input data showed high classification accuracy compared with the land cover map generated using the original RapidEye images.

We found an unrecorded endophytic fungus, Dermea piceina J.W. Groves, isolated from alpine conifer Abies koreana. Until now only one Dermea species, D. cerasi, has been reported in Korea. In this study, we compared morphological characteristics and DNA sequences, including internal transcribed spacer and 28S ribosomal DNA, of D. piceina isolated from A. koreana with those of related species. Here, we present morphological and molecular characters of this fungus for the first time in Korea.

Lambertella corni-maris Höhn., an endophytic fungus that is an unrecorded species in Korea, was isolated and cultured from alpine coniferous Korean fir. The Lambertella sp. was found in Korean pine in Yeongwol-gun but no Lambertella spp. were recorded elsewhere in Korea. In this study, the morphological characteristics and molecular barcode sequence of L. cornimaris were compared to its related species. We tried to explain the cultural characteristics and microstructures, such as the conidia of L. corni-maris, compared to closely related taxa and present it.

We report on an unrecorded endophytic fungus, Grovesiella abieticola (Zeller & Goodd.) M. Morelet & Gremmen isolated from Abies koreana of Mt. Halla in Jeju. In this study, we used a culture method to determine its conidia and compared relative species using an internal transcribed spacer (ITS) 1, 2, and 5.8S ribosomal DNA sequence. Thus, we present the cultural characteristics and morphology of G. abieticola in this paper.

An endophytic fungus, Rhizosphaera pini strain NIE7426, was isolated from the sub-alpine coniferous tree Abies nephrolepis in Mt. Nochu of Gangwon Province. It was characterized by macroscopic and microscopic features, as well as the internal transcribed spacer (ITS) 1, 2 and 5.8S sequences. All morphological and molecular features support the first recognition of this taxon in Korea. In addition, this study adds A. nephrolepis as a host plant R. pini.

이 연구는 국내 로드킬(Roadkill) 피해 발생건수가 가장 높은 야생동물인 고라니(Hydropotes inermis)를 대상으로 로드킬 예방에 필요한 저감시설인 유도울타리의 적정 높이 기준을 마련하기 위해 이루어졌다. 이를 위해 국외 사슴류 흰꼬리사슴(Odocoileus virginianus)의 울타리 월장 측정 연구사례와 비화학적 포획 방법을 검토하여 국립생태원 사슴생태원에서 관리하는 고라니 27마리를 대상으로 울타리 월장 실패율 측정 방법에 적용하였다. 펜스(test fence) 높이 0.5m에서부터 단계별 10cm씩 높여가며 넘을 수 없는 높이를 검증하였다. 그 결과 1.5m로 설치할 경우 고라니의 침입을 96.7% 차단 가능하고, 1.8m 높이에서는 100% 차단하는 것으로 확인되었다. 이 연구결과를 토대로 향후 환경부 "생태통로 설치 및 관리지침" 개정 시 유도울타리 적정 높이 기준 설정에 의미 있는 자료로 활용될 것으로 기대된다.
