The purpose of this study is to evaluate the damages that may cause if the terrorists attack Kaohsiung Harbor. After the terrorists attacked the World Trade Center in New York City, they extended their attacks to the southeast Asia-- the explosion in Bali Island and Philippine. Then people all of the world started to be alert about these terror attacks. There is no exception in Taiwan, we have to be prepared to cope with this crisis. This study does the staff survey and physical exams the Harbor's security facilities to evaluate the operation of the Harbor. Hopefully it will be a good reference to the Authority and people work there.
