Improvement in personal computing performance seems to know no bounds. While flood simulation systems used to require a supercomputer, high speed modeling is now possible on personal computers. In this paper, I would like report on the current progress and use of the latest disaster simulation systems developed by Hitachi's Central Research Laboratory for disaster prevention purposes. I would also like to propose their application in the case of coastal area disasters, the risk of which is thought to be increasing due to rising sea levels caused by global warming.

Seaweed holds an important position in coastal ecosystems as a primary product, playing a role in the maintenance, restoration, and conservation of seafood resources. It has been shown that by using the fertility and functions of artificially introduced 'drifting seaweed E carbon dioxide in the atmosphere can be recycled, the living resources accompanying 'drifting seaweed Ecan be conserved, and eutrophic ocean areas can be cleansed. It is important to remember Applied Algology research when thinking about the effective use of coastal and ocean resources and conservation of the marine environment.

In the latter half of the 10th century, a woman who served as no more than a local priestess on the coast of Fujian province in China became an object to faith to regional seafarers and their protector goddess. That is the origin of Maso. Her faith has now spread beyond China to Taiwan and Southeast Asia, where Maso shrines can be found and where she is worshipped not only as a goddess of the sea but of profit in general. Maso affords us a wider view of the East Asian world from an ocean perspective.
