The purpose of the study is to develop an integrated knowledge structuring system for the domain of engineering, in which ontology-based literature mining, knowledge acquisition, knowledge integration, and knowledge retrieval are combined using XML-based tag information and ontology management. The system supports combining different types of databases (papers and patents, technologies and innovations) and retrieving different types of knowledge simultaneously. The main objective of the system is to facilitate knowledge acquisition and knowledge retrieval from documents through an ontology-based dynamic similarity calculation and a visualization of automatically structured knowledge. Through experimentations we conducted using 100,000 words economic documents reported in the "Go！ Japan" project for analyzing Japanese industrial situation, and 100,000 words molecular biology Papers, we show the system is Practical enough for accelerating knowledge acquisition and knowledge discovery from the information sea.

This paper has focusing CheongHaeJin's maritime trading activities between Korea, China and Japan in the 9th century. In operation of CheongHaeJin which Chang BoGo was given a key role, CheongHaeJin creates three nation's wealth in triangular trade among Korea, China and Japan. And also, CheongHaeJin's contribution is considerable to the maritime trade development of Northeast Asia through establishing trading advance base in China and Japan, and organizing Shilla's people in China. Chang BoGo justified the control over small business groups of the west and south sea of Korea and the east and south sea of China by keeping pirates away His trade groups controlled foreign trade of three countries: Shilla, the Dang Dynasty of China and Japan. They connected Persia, India, Southeast Asia, and China. CheongHaeJin's key success factors of the maritime activities are summarized as follows; There is a possibility of searching that successful factor from the people of operator of CheongHaeJin. Based on oceanic adventurous spirit with character and progressive thinking could complete the rally of sea influence and composition of fleets. Secondly, the success factor is the excellent operational ability and leadership which learned in the Dang Dynasty of China. Thirdly, In 9th century, International political context was suitable for CheongHaeJin's construction and operation. Such political circumstances had given to CheongHaeJin remunerative position. Finally, Although central government could not maintain the sea traffic securities, Chang BoGo's ocean trading fleets guaranteed the safe fishing industry of people and security of sea traffic.

Taking the great advantage of Subaru's wide field coverage both in the optical and in the near infrared, we have been providing panoramic views of distant clusters and their surrounding environments over the wide redshift range of 0:4 < z < 3. From our unique data sets, a consistent picture has been emerging that the star forming activity is once enhanced and then truncated in galaxy groups in the outskirts of clusters during the course of cluster assembly at z < 1. Such activity is shifted into cluster cores as we go further back in time to z ~ 1.5. At z = 2 - 2.5, we begin to enter the epoch when massive galaxies are actually forming in the cluster core. And by z ~ 3, we eventually go beyond the major epoch of massive galaxy formation. It is likely that the environmental dependence of star forming activity is at least partly due to the external environmental effects such as galaxy-galaxy interaction in medium density regions at z < 1, while the intrinsic effect of galaxy formation bias overtakes the external effect at higher redshifts, resulting in a large star formation activity in the cluster center.

For a safety supervision, watching a restricted area so that no one go there is very important. This has been mostly accomplished by people. They keep an eye on many monitors at onece for a long time. It, however, is too simple and boring to concentrate it for a long time. So it's worth while to construct a watching system by image processing. And the system we made is now actually working at a certain hydroelectric power plant and some other restricted areas in Japan.
