The purpose of this study is to reveal how alien species are dealt with in textbooks about living environment studies, science, and biology from elementary to high school. From an analysis of students’ responses in lessons about alien species, possibilities and points to be noted for executing science lessons about biodiversity in elementary school were also examined. As a result, the following three points were identified.(1) The textbooks checked in this study have a total of 126 kinds of alien species, of which 10 are alien invasive species, and 23 are careful invasive species.(2) The textbooks have some description of how to cope with the problem of invasive species for most of alien invasive species; they also and have descriptons suggesting that their multiplication and release are encouraged, wheras there is little description about careful invasive species. (3)There are lessons that we had suggested to the students for proper understanding of alien species, indicating that lessons that encourage understanding of alien species in elementary school are possible. We have to examine opportunities and contents for doing so.

Typhoon "Rusa" (No.0215) attacked the Republic of Korea from August 31 to September 1, 2002. Depended on this typhoon, the heavy rainfall was brought through the Korean Peninsula. In Particularly, 100mm of hourly precipitation and 870mm of one day precipitation were recorded on August 31 in Kangnung where is located in the north-east of Korea. The accumulated precipitation at Kangnung amounted to 898mm from August 30 to September 1. During heavy rainfall, many slope failures occurred. The one failured slope was investigated in this study to make clear the mechanism of slope failure with special attention to clay veins developed on it by means of X-ray diffraction, optical microscope, scanning electron microscope, transmission electron microscope and computer simulation.
