  13. The aim of this study is to contribute an efficient promotion of research and development (R&D) in the field of energy technologies by evaluating them from the viewpoints of global warming mitigation and invested R&D resources, such as expenditure on R&D.Main subjects of this study is as follows,- To estimate relationships between invested R&D resources and energy efficiency improvement in energy technologies statistically and model their relationship by a function,- To give an optimal allocation of resources to R&D in energy technologies which have great potential of global warming mitigation through energy efficiency improvement by formulating with mathematical programing.

  13. In order to develop a mnumerical model estimating the behavior of discharged pollutants to coastal environment, we survayed distributions and behaviors of chlrobenzens and butyltins in Ise Bay. Their distribution patterns in the surface sediment were explained by the following effects: the distance from the source, the horizontal transport caused by the river inflows, and the sedimentation caused by downward water flow. The transportation of the pollutants from surface water to bottom sediment was explained by the process of their absorption to suspended matter and their settling on suspended matter.

  13. Most mutagenic compounds in the environment are activated by metabloic enzymes in human liver. In the conventional mutagenic bioassay systems, extract from rat liver has been used for an alternative of human liver extract. This study aims to establish yeast and mammalian cell lines that express the human metabolic enzymes by the genetic engineering and assay mutagenicity of environmental compounds with the recombinant cells.
