In this research, an idea for the utilization of micro-bubbles to the improvement of water quality in an semi-enclosed coastal sea is examined. In the idea, micro bubbles are put into the sea with the thermal discharge of an existing power plant. Since the ascending velocity of micro-bubbles is rather small, they are expected to spread widely with the thermal discharge and to contribute to the rise of the dissolved oxygen concentration of the sea. The convection of micro-bubbles as well as changes of water quality are investigated by the three dimensional fluid simulation. Economical efficiency regarding to the scale of the micro-bubble generating equipments is discussed.

The methodology is one of the most pressing matters for advancing "Environmental Physics". Studying the essence of life phenomena shows us that a reductionistic approach for one place is not enough at all and it might be even worse for solving environmental problems. On the contrary, it is also very important to find emergence patterns which recognized by the same ecological studies about many other places (or many other past periods in the same place). Both of these methods, the reductionistic approach within one place and finding emergence patterns out of many places including that place, are important and complement for us to solve today's environmental problems on earth.

From the year 1999, the author has been creating lectures for The Study of Publishing Media 2 of the Faculty of Environmental and information Sciences in Yokkaichi University. The lectures have been experimental trials for developing the ability of media literacy focused on current Internet Media in particular. In the last year, students at this lecture were given 5 themes, and they reported to the author by internet e-mail, and then the reports were displayed with comments from the author in the specific secure Homepages domain. This report describes the process above and the results.

American Higher Education is one of the world' s largest and most highly regarded educational systems. It educates more than 13 million students in over 3,500 schools. Although it is possible to speak of American Higher Education in general terms, it is actually comprised of four main types of schools, each with somewhat different goals and historical development. There are public and private four year universities and colleges, two year private colleges and two-year public community colleges. This paper will look at some of the issues and questions that arise when one looks at the historical development of these four types of schools.

Festus lyayi is considered not only one of the major novelists in Nigeria, but also one of the most politically committed African novelists. His novels, with uncompromising and radical political perspective based on the tradition of social realism, are comparable ideologically to those of Sembene Ousmane in Senegal and Ngugi wa Thiong'o in Kenya. Festus lyai, as a key figure in the trade union movement, had struggled against the military dictatorship for most of the 1980s. He was arrested on charges of treason in 1986, and dismissed from the faculty of the University of Benin for his revolutionary political and labour activity. Nigerian political climate has been very severe. In Nigeria,"Corruption has become not just a way of life, but life itself. Military officers live above the law; the judiciary has been totally intimidated, corrupted, compromised and rendered useless; traditional institutions have been domesticated and bastardized; trade unions, student associations, prodemocracy movements and other popular coalitions have been suppressed and their leaders jailed or forced into exile; unemployment and under-employment have reached unprecedented levels."(Globalization and the Dilemmas of the State in the South, Macmillan Press LTD, 1999). Awaiting Court Martial, published in 1996 under such Nigerian socio-political conditions, is a collection of short stories by Festus lyayi. 'Noruwa's Day of Release (I)', is one of the short stories included in Awaiting Court Martial. In this story, it is vividly depicted through the protagonist 'Noruwa' that innocent civilians, caught in the crossfire of corrupt and murderous conflict, cannot be cured and cannot lead an ordinaly human life even after the civil war because the socio-political situation has not basically changed at all. Those who have read the story cannot help reflecting on the necessity of changing the status quo, the military regime that has been torturing common people both physically and mentally.
