Information Sciences

Lecture and Laboratory Programs:

Course contents include the following:

  • physical science
  • computer science
  • physical experimentation
  • medical physics
  • medical statistics
Program Objectives

By the completion of the program, students will:

  • acquire scientific thinking and methodology through physical and mathematical analyses of natural, social and life phenomena, and develop abilities to observe and analyze phenomena through experimentation.
Main Areas and Themes of Study
Faculty Research and Studies

The faculty conducts scientific research in various disciplines.

  1. Experimental studies (plasma and cosmic-ray physics)
  2. Computational physics (Monte Carlo simulation)
  3. Medical studies (Epidemiology, medical informatics, medical engineering)
Selected List of Research Studies
  1. Study of the plasma-wall interaction in fusion science and vacuum science
  2. Observation of cosmic rays
  3. Monte Carlo simulation of charged particle transport for radiology

Biology

Lecture:

A comprehensive introduction to biology. The course covers a broad range of disciplines, including histology, genetics, cell biology, developmental biology, evolutionary biology, neurobiology and ecology.

Laboratory program:

This program offers basic techniques to observe cells of various tissues. Experiments include artificial fertilization of loaches to observe how mature organisms develop from a single cell.

Student Learning Outcomes

Students who successfully complete the programs will be able to:

  • describe basic biological concepts and principles.
  • explain the ecological relationships between organisms and their environment.
  • perform basic laboratory techniques.
  • explain the developmental processes of animals.
Research Interests

Freshwater sponges : My research focuses on taxonomy, phylogeny and ecology of freshwater sponges. With molecular biological data and morphological characteristics, we study Baikalian sponges, as well as Japanese ones, to define the phylogenetic relationships of sponges.

Circadian Clocks : We are interested in the circadian clock system, which helps living organisms adapt to the daily cycling of environmental conditions. Our current research focuses on unveiling the output neuronal circuits that conduct the circadian cues from the core clocks to the peripheral effectors, using molecular genetic and immunocytochemical approaches in the fruit fly Drosophila melanogaster, and in the ant Camponotus japonicus.

Chemistry

Knowledge of chemistry is imperative for an understanding of the life sciences, which is necessary for the acquisition of knowledge in current medicine. Therefore, essential chemistry is taught to students who aim to be clinicians.

Program Objectives
Lecture Section

Structures, properties and functions of materials causing vital phenomena are described at the atomic and molecular levels.

Laboratory Programs

Both experimental techniques and a fundamental knowledge of chemistry will be acquired through the following exercises:

  • volumetric analysis with acid and base
  • pH and buffered solution
  • absorption spectrophotometry of urinary samples
Research Interests
  • Studies on the oxidative stress-related gene polymorphisms.
  • The utilization of NIE and computer network in chemical education.
  • Synthesis of titanate salts via liquid-phase synthesized titanate nanosheets.
  • The nano risk evaluation of titanate nanosheets.
