Division of Marine Bioresource Science

The objective of this division is to conduct research and deliver educational programs on diverse marine bioresources with special reference to their biological and resource science aspects. In particular, the conservation mechanism of their biodiversity and the process of bioproduction of marine organisms are investigated at all levels: molecular, cell, individual, population and community. The aim is to ascertain bioresource sustainability, which will provide invaluable basic and scientific information for fisheries for effective resource management.

Laboratory of Marine Bioresource Production (Keywords: Ecology, Fish and Invertebrates, Biodiversity, Life History)

The laboratory aims to conduct research and deliver educational programs that evaluate the potential productivity of marine organisms in the Kuroshio coastal area. Also, it aims to develop an understanding of the conservation mechanism of its biodiversity. This objective is based on research carried out on food-chain structures, early life histories, reproductive strategies and interrelationships among the organisms living in the tideland, algal bed and coral reef ecosystems located in the area.

Division of Environmental Science

Environmental science is study using the knowledge and techniques of both natural and social science. The main focus of this division is on the natural environment and the anthropogenic impacts on the Kuroshio area. In addition, changes in the natural environment and population are also studied. Finally, from the results of the division’s research programs, practical techniques and solutions for improving both the natural environment and human population are proposed.

Laboratory of Environmental Conservation (Collaborative Laboratory by Visiting Professors: Keywords: Marine Chemistry, Aquatic Microbial Ecology, Marine Biotechnology)

The main focus is on the ecosystem of the Kuroshio area in regard to the environmental sciences of biology and chemistry. In addition to this, the research of the laboratory tries to elucidate what the appropriate ecosystems are and how the ecosystems are affected by anthropogenic impact, and to clarify the mechanisms of eutrophication and the breakout of red tides. Finally, environmental conservation and practical techniques for improvement or bioremediation of the environment are proposed.

Laboratory of Environmental Change and Sustainable Society (Keywords: Meteorology, Economics, Geography, Geology, History)

This laboratory aims to analyze environmental change and sustainable society in the Kuroshio coastal area from the viewpoint of natural and social sciences. It especially focuses on the interaction between environmental change and change in the Kuroshio coastal area. The interaction due to environmental changes in the atmosphere, hydrosphere and lithosphere is examined in terms of earth science. In addition, historical changes to societies in the area are analyzed through social science. The practical methods for conservation, and the effective use of natural resources and the environment in the Kuroshio coastal area are also synthetically analyzed based on natural and social sciences.

Division of Human Health and Medical Science

The Kuroshio area has extensive bioresources basic to human health in terms of nutrition, physical exercise and relaxation. In addition to marine bioresources, the Kuroshio area has other resources important to people such as climate, coastal geographical features, and culture. The purpose of this division is to isolate biologically active substances from marine bioresources and derivative foods and elucidate the structure of the active compounds. Furthermore, research is carried out on how to apply these bioactive compounds to the improvement of human health. Finally, the division encourages and supports researchers who can contribute to the application of the marine and environmental resources of the Kuroshio area to human health in association with medical schools and hospitals.

Laboratory of Human Health and Medical Science (Keywords: Immunology, Pharmaceutical Science, Molecular Biology, Food Science)

The laboratory engages in research and education in human health and medical science by investigating the effects of marine bioresources on human health from the point of view of immunity and nutrition. It focuses on the identification of beneficial compounds to human health from marine bioresources through structural analysis. Also, it investigates food materials developed in the Kuroshio area based on its rich resources in terms of nutrition and food chemistry. Furthermore, the laboratory plans to investigate the effects of bioactive molecules from marine bioresources and foods on immune response against pathogens and cancer cells. It will also examine the possibility of developing medicine regulating immune response positively or negatively.

Division of Human Science

Aging and population decrease in rural areas causes various social and economic problems. In the Division of Human Science, we study these problems focusing on the interaction between the individual and society or the environment in terms of medical treatment and nursing. These problems have rapidly progressed in the mountainous areas of Kochi Prefecture where one of the world’s most elderly populations lives, which is a situation that is also expected to quickly develop in other Asian countries. We propose possible ways to solve these problems.

Laboratory of Human Science (Keywords: Aging, Medical treatment, Nursing, Rural area)

Aged people tend to develop pneumonia due to a marked decline in their immune systems. They could easily become bedridden, once they get sick. Therefore, we study the roles of food and nursing, which are important in keeping them healthy. Furthermore, we study and educate about the methods of care that help aged people to be independent and improve their quality of life (QOL).

Also, we study the roles of nursing for the children who grow up with having some disabilities and/or health problems and their family. Through these research and education, we encourage researchers to collaborate with interdisciplinary team and to deliver the children & family-centered care.
