Since ship captured accidents have been frequently occurred around Japan, it is sometimes regarded as freak wave as a cause of these accidents. Generally effects of swell are not well considered for wind wave modeling and their contributions to wave height statistics are unknown. A series of the wind-wave experiments was carried out using a wind-wave tunnel and numerical experiments using spectral wave model were also conducted. The energy growth of pure windsea and swell-windsea fields are analyzed in detail. The swell effects on the wave statistics, such as kurtosis and skewness are investigated. The effects of swell enhace the extreme waves if the windsea energy is close to the swell.

The C (aryl) -O bond formation was generally carried out by using transition metal-catalyzed coupling reaction between aryl halide and alcohol. Among them, Cu-mediated Ullmann reaction is a powerful method for the preparation of alkyl aryl ether from secondary alcohol. In this article, recent advances in Ullmann reaction are reviewed being categorized into two parts: ligand and aryl donor.
