In previous studies, Cyclooxygenase-2(COX-2) is believed to be linked with inflammations and tumors. But in recent reports, COX-2 is found to play important roles in osteoblastic mechanotransduction and in bone remodification and resorptions in some ways. It was found that mechanical stretches, such as hydrostatic forces and pulsating fluid flow, could increase the expressions of COX-2 mRNA and then prostaglandins, and activate many signal pathways in osteoblasts.

By using two different three-dimensional source distri- bution techniques, three-dimensional translating-pulsating source (3DT) and three-dimensional pulsating source (3DP), numerical investigations have been carried out for a high speed monohull ship (RD-200) advancing in oblique waves. The numerical results are compared with experimental values obtained from wave load tests carried out at the SSPA. These extensive test results cover different wave directions at a wide range of wave frequencies.
