This paper investigates the influence of the ultrasonic waves that are included in the sounds of costal waves on human brain waves, by experimenting using CD recorded wave sounds. The experiment was conducted using a full range pass sound, and low range pass sound which is not including high frequency band width to 26 subjects and was measured amounts of brain wave activity in 4 different type of brain wave frequency, delta, theta, alpha and beta waves respectively. State of activity of brain wave was also expressed on brain wave map. At the same time, using the YG test and Profile of Mood States (POMS), brain reaction by personality and psychological evaluation were also examined. As the result, author obtained that ultrasonic wave affects to human brain with statistically significant.

Mekong Delta is a big rice production area and an important place in the socio-economic development of Vietnam. Especially, Dong Thap Muoi (DTM) shares large production area in Mekong delta. Although the floods happen every year, the people still live there. At present, in order to reduce flood damage, the Government proposes projects to build Flood Safety Zones (FSZ) in this area and in fact, some of them have already been constructed. However, there are many people who do not wish to relocate to these zones.<br>In order to define the above, a questionnaire survey on resident migration during floods, resident's attitudes about moving to FSZ was conducted. The survey indicated that the most of all households need to find a place to evacuate. The "main road" and "peoples' house" are the most common responses to the location of evacuation. It was found that 1 km to 5 km appear to be the maximum desirable distance to the field. Every year, resident spends over 1/5 of annual income for house repair. Environmental problems caused by water, such as skin disease, sanitary, drinking water supply during flood were also revieled.<br>Finally, based on the obtained results, points of consideration to the planning of FSZ were discussed.
