ABSTRACT：In recent years, new marine use projects for solving global environmental problems and energy problems have been eagerly promoted, and therefore measures for coexistence with local fisheries are required. In this paper, we examined the requirements for coexistence between fisheries and new ocean use development by analyzing the process that the fisheries sector acceped the deep sea water development project of Kumejima. The following results were derived; (1) The project is a project with extremely high local public interest that has developed the local industry of Kumejima. (2) With regard to a new regional resource, i.e. deep ocean water, high fishery value was created through the technical development of aquaculture production, its transfer, and the mechanism of practical application. (3) The fact that the initial project purpose of deep ocean water development was mainly fisheries use and that it was defined that it would contribute to regional development encouraged fishermen's active participation and extremely smooth consensus building. (4) For deep sea water development of Kumejima, cooperation between politicians and administrative staff (including researchers) that have gained the trust of fishermen worked effectively.

ABSTRACT : This paper investigates the effects of a virtual reality experience on an individual’s awareness and behavior regarding environmental issues. Test subjects were shown a 360 degree panoramic video of coastal environments while brainwave activity was monitored. Test subject’s general reception to the experience was investigated, and the correlation between the physiological parameter of brainwaves and change in behavior was evaluated using the cause model. As88% of test subjects expressed wishes to experience virtual reality again, general reception of the experience was adjudged to be good. It was deducted that subjects who displayed an increase in cause model phase due to the virtual reality experience, will display a change in behavior provided they have easy access to bodies of water.

ABSTRACT: The area outside of a port's seawalls, where many offices and factories are located, is vulnerable to storm surge flooding, and thus when the flooding occurs, it may greatly harm logistics and industrial activities. If many tide stations are placed in the area to reduce the danger, substantial cost and time would be necessary for the installation and maintenance. A verification test of simple tide level measurement devices (ultrasonic and hydraulic pressure gauges) was carried out near the permanent tide station in Kinuura port to determine the accuracy of the sea level measurement. As a result of the comparison of the tide records from harmonic analysis between the simple tide level measurement system and the permanent tide station, total amplitude of the four major tidal components differedby1%between them. Like wise, hightide and low tide values differed by equal or less than 1.2 minutes. The difference in mean high tide interval, calculated from the retarded, was approximately 1 minute between the simple measurement devices and the permanent tide gauge. These results indicate that the simple measurement system has sufficient accuracy for measuring tide level in the port. Finally, technical considerations for the installation, maintenance, and data communication and handling on the system are summarized.
