Damage from typhoon disaster can be mitigated by grasping and dealing with the damage promptly for the regions in typhoon track. What is this work, a technique to analyzed dangerousness of typhoon should be presupposed. This study estimated 10 m level wind speed using 700 hPa wind by typhoon, referring to GPS dropwindsonde study of Franklin(2003). For 700 hPa wind, 30 km resolution data of Regional Data Assimilation Prediction System(RDAPS) were used. For roughness length in estimating wind of 10 m level, landuse data of USGS are employed. For 10 m level wind speed of Typhoon Rusa in 2002, we sampled AWS site of $7.4{\sim}30km$ distant from typhoon center and compare them with observational data. The results show that the 10 m level wind speed is the estimation of maximum wind speed which can appear in surface by typhoon and it cannot be compared with general hourly observational data. Wind load on domestic buildings relies on probability distributions of extreme wind speed. Hence, calculated 10 m level wind speed is useful for estimating the damage structure from typhoon.

This study is a basic research with the aim of developing the method of judging the leakage zone by grasping the habitat characteristic of agricultural reservoir slope in inhabiting characteristics appear differently according to natural inhabiting environment. To this end, this study is intending to investigate slope vegetation using a quadrat technique at Sinheung reservoir located at Gwangsi-myeon, Yesan-gun, Chungnam, and to perform the analysis of importance value using relative frequency and relative coverage, etc. Also, this study intended to present the necessity of having to consider the eco-system of the relevant region in time of a reservoir slope afforestation for the time to come by suggesting that the reservoir slope vegetation after a stable period becomes similar to the regional vegetation by comparing this study result with the existing research which carried out the analysis of importance value of forest vegetation for Yesan Region. The reservoir slope vegetation is similar to the indicator species which appear in the regional forest vegetation, so there was a need to select afforestation species in the light of this in time of slope afforestation. As a result of the analysis of the importance value, this study grasped that there was an emergence characteristic similar to the vegetation at a birthplace of a forest fires because growth and development of forest trees, and perennial plants were restricted by annually implemented brush-cutting work, etc.; however, indigo plant and bush clover, etc. were found to show the characteristic differing from this. Consequently, this study was able to confirm that there is the necessity of having to create the Importance Value Table suited for reservoir slopes by region through a lot more data construction in the near future.

The purpose of this study was to help in explaining the necessity of education on complementary and alternative medicine(CAM) and opening relevant curriculums in nursing education by grasping the kinds of CAM in which nursing students want to be opened. Data were collected from September 27, 2003 through October 20, 2003. A group of 865 nursing students were surveyed using questionnaires in seven universities whose curriculums on CAM have not been available. Collected data were statistically analyzed by using SAS 8.02 system, and the study results are as follows: 1. The average of subjects' behavior toward CAM was 3.52 of the total 5 with practical affairs 3.79. medical treatment 3.79, social concerns 3.84, and communication 3.78. 2. Most nursing students $(90.6\%)$ did not precisely understand the meaning of CAM although they had heard of it. Most of them $(85.5\%)$ had no experience of applying CAM. The study also revealed that more qualified CAM lecturers in the future are needed: specialist in the relevant field $(83.2\%)$, doctor and herb doctor $(6.5\%)$, clinical nurse $(6.0\%)$ and professor of the department of nursing science $(4.3\%)$. 3. Concerning students' behavior toward CAM, there were statistically significant difference between students from agrarian and fishing villages (F=4.91. p=.007) and the others. 4. CAM courses that students want were therapeutic touch (massage) $(22.9\%)$. aroma therapy $(14.8\%)$, manual healing methods $(14.7\%)$, treatment of blood vessel $(8.3\%)$, foot reflexology $(7.9\%)$, and heart remedy $(6.8\%)$. In conclusion, the study indicated that nursing students had positive attitudes toward CAM and for this. healers should have a frank talk with patients in order to maximize symptom-relieving effects. However, the study showed that most nursing students did not understand the exact meaning of CAM. Considered the fact that improvement of both health status and quality of life will be an important issue in the future, active introduction and education of CAM in nursing curriculum are a matter of necessity.

Rivers refer to either natural or artificial structures whose primary functions are flood control and water conservation. Due to recent localized torrential downpours led by climate change, large amounts of eroded soil have been carried away, forming deposits downstream, which in turn degrades the capacity to fulfill these functions. To manage rivers more effectively, we need data on riverbed erosion and deposition. However, environmental factors make it challenging to take measurements in rivers, and data errors tend to prevent researchers from grasping the current state of erosions and deposits. In this context, the aim of the present study is to provide basic data required for river management. To this end, the author made annual measurements with a Real-time Kinematic-Global Positioning System (RTK-GPS) and a total station in Pats Cabin Canyon, Oregon, United States, and also prepared thematic maps of erosion and deposition thickness as well as water depth profiles based on a GIS spatial analysis. Furthermore, the author statistically analyzed the accuracy of three dimensional (3D) measurement points and only used the data that falls within two standard deviations (i.e. ±2σ). In addition, the author determined a threshold for a DEM of Difference (DoD) by installing measurement points in the rivers and taking measurements, and then estimated erosion and deposition thickness within a confidence interval of ±0.1m. Based on the results, the author established reliable data on river depth profiles and thematic maps of erosion and deposition thickness using pre-determined work flows. It is anticipated that the riverbed data can be utilized for effective river management.

Korea High-Speed Railway has various safety systems to secure safe and stable transportation and makes assurance doubly sure to minimize casualty and property damage caused by natural disasters. But, there is no regulation that reflects domestic railway line, climate, topographical and geological characteristic in introducing the foreign regulations yet. Therefore, it is necessary for us to modify a regulation which is suitable to domestic high-speed railway. In this study, it is possible to establish more reasonable boundary rainfall by grasping and improving the troubles with existing boundary rainfall that is scheduled to be utilized for high-speed rail-transport operation control under rainfall. Also, it is possible to insure the safety of train by four steps such as 'normal operation', 'warning issue', 'train speed control' and 'train stop' using the established boundary rainfall. It will go far toward minimizing the occurrence of natural disasters.
