To characterize the site specific properties of a study area for high-level radioactive waste disposal research in KAERI, the several geological investigations such as surface geological surveys and borehole drillings were carried out since 1997. Especially, KURT (KAERI Underground Research Tunnel) was constructed to understand the further study of geological environments in 2006. As a result, the first geological model of a study area was constructed by using the results of geological investigation. The objective of this research is to construct a hydrogeological model around KURT area on the basis of the geological model. Hydrogeological data which were obtained from in-situ hydraulic tests in the 9 boreholes were estimated to accomplish the objective. And, the hydrogeological properties of the 4 geological elements in the geological model, which were the subsurface weathering zone, the log angle fracture zone, the fracture zones and the bedrock were suggested. The hydrogeological model suggested in this study will be used as input parameters to carry out the groundwater flow modeling as a next step of the site characterization around KURT area.

Geological and geophysical surveys were performed to examined the cause of the rock-mass slide occurred at the opening site of the Wanglim tunnel of the Seoul-Pusan High Speed Railway. The results of geophygical survey and geometrical analysis for the geological structures indicate that the rock-mass slide was triggered by the heavy rainfall which increases the groundwater level and results in high pore pressure in the N60$^{\circ}$ E-trending major fractured zone of the slope, and that the foliation dipping toward the vertical open face of the slope acted as a main sliding plane during movement.

곤충 혈림프에서 존재하는 리포포린은 선택적으로 지질을 지질 사용및 저장기관으로 운반한다. 본 연구는 유충지방체, 성충난소 및 정소로 지질의 운반과 유충지방체 및 성충난소로 리포포린 자체가 흡수되는 과정을 조사하였다. 이들의 기능을 조사하기 위해 FITC-labeled 리포포린과 DiI-labeled 리포포린을 사용하였다. 유충지방체, 성충난소 및 정소를 DiI-labeled 리포포린과 배양한 결과 리포포린으로 부터 각 기관으로 지질을 운반함을 알 수 있었고, 또한 receptor-mediated endocytosis 억제제인 suramin, unlabeled 리포포린과 배양한 결과는 리포포린에서 각 기관으로 운반되는 지질의 양이 현저하게 감소함을 알 수 있었다. 또한, 유충지방체와 성충난소를 FITC-labeled 리포포린과 배양한 결과 위에서 언급한 지질 뿐만 아니라 리포포린 자체도 각 기관의 에너지원으로 사용하기 위해 흡수된다는 사실을 알 수 있었으며, suramin과 unlabeled 리포포린과 배양한 결과 리포포린 자체가 흡수되는 양이 현저하게 감소함을 알 수 있었다. 위 실험결과로부터 리포포린에 의한 지질의 운반과정과 리포포린 자체의 흡수과정이 receptor-mediated endocytosis로 이루어짐을 알 수 있었다.
