Plankton collected from Lake Utonai-numa, Hokkaido, in August, 2000 was studied. 77 taxa of zooplankton and 171 taxa of phytoplankton were found in this lake, the abundant species being Arcella discoides, Centropyxis aculeata, Centropyxis hirsuta, Bosminopsis deitersi, Tabellaria fenestrata, Spirogyra sp., Pediastrum araneosum, and Pediastrum boryanum var. longicorne. Some species such as Phryganella nidulus (Protozoa), Cyphoderia trochus (Protozoa) are found for the first time in Japan. llyocryptus ezoensis and Eurycercus nipponica are neu species.

Flow characteristics of Nagoya bay in the summertime were investigated by means of the three-dimensional numerical simulation. Variations and mean distributions of current, salinity, temperature and dissolved oxygen were determined for 2 months in the summer 2000. Comparison with the observed data were fairy well. The strong effect of the salinity distribution outside the bay to the vertical circulation of the bay was found over the whole period of the simulation. From this fact, it was concluded that understanding the behavior of the water mass outside the bay is indispensable for the water quality control of Nagoya bay.

3D turbulent flow structures around sub-merged inclined spur dikes are numerically investigated. The basic equations of the numerical model are derived on a generalized curvilinear movable coordinate system with full-staggered arrangement of hydraulic variables. A 2nd order non-linear k-ε model with effects of the strain parameter and the rotation parameter is adopted as a turbulence model to simulate the complex turbulent flows with separation and vortex shedding from the edge of the spur dikes. Numerical results are compared with the results in the PIV measurements by Tominaga et al (2001) and the model performance is examined. The present numerical model could reproduce the fundamental aspect of the 3D turbulent flow features influenced by the inclination angle of the spur dikes. The effects of the inclination angle are clarified in both the averaged flow patterns and the fluid oscillations. In time averaged flow fields, the flow from the bank toward the main flow is dominant around the downstream inclined spur dikes while the reverse flow is dominant around upstream inclined ones at the vicinity of the bed. The amplitude of the fluid oscillation around the downstream spur dikes is much larger than that around the upstream ones. The period of the fluid oscillation is in compatible with the first mode in the impinging shear layer.

Since the author was assigned to the media division of the Faculty of Environmental and Information Sciences at Yokkaichi University, members of the Electronic Publishing Seminar have been pursuing the creation of new media by utilizing advanced digital technology. They published the first issue a newspaper style media tilted "iMargin" in October 1999,which was followed by the second issue in May 2000. Finally they published the third issue which was a 32 page magazine style "iMargin" in April 2002. With the reality of the advancement of publishing technology and the development of new infrastructure like the Internet, and with the author's mission as a media creator for 20 years, this report describes the educational vision of media expression, composed of digital contents.

In this paper, we introduce the tracking of objects using camera which is connected to network. We intended to develop monitor system using this network camera. It produces JPEG image sequences, and has functions of panning or tilting controlled over network. The tracking procedure is based on Pfinder which was developed in Media Lab., MIT. The results in the condition of low frame rate show the possibility of tracking over Internet.

Recently, the efficient transportation, delivery system has become important in order to reduce the cost and the environmental crisis (energy, CO_2 and so on). In this paper, transportation and delivery problems, are classified four categories, that is, transportation-means choice problem, delivery scheduling problem, transportation scheduling problem and goods packing problem. For the second and the third problems, many kinds of sub problems are defined by giving various structures and various restrictions to order and resources. And, algorithms to solve such sub problems are defined briefly.

Globalization, as well as localization, has been focused for the recent years in the issues of the modern society, and whether global or local is not the ultimate choice anymore. There could be the third way of "glocalism" to deal with the balance of the two. This study is experimental in extracting the essence of "glocalism" out of the Caribbean short fiction in which a global life meets local in a crossroad of the rural Jamaica.
