The Japanese Cattle industry has been undergoing major changes for
the past three decades. During the 1950's and 1960's mechanized
power rapidly. The process of beef industry structure change
accelerated in the 1970's as medium scale feedlots came into being,
regional packing plants were established, and the beef marketing
system matured. Economic forces, both within and external to the
industry. A major objective of this book is to test the authors'
hypothesis that beef production by Japan's cattle industry could
become competitive with imported beef.

In this thesis, the author develops new high-power millimeter wave
techniques for measuring the hyperfine structure of positronium
(Ps-HFS) directly for the first time in the world. Indirect
measurement of Ps-HFS in the literature might have systematic
uncertainties related to the use of a static magnetic field.
Development of the millimeter wave devices supports the precise
determination of Ps-HFS by directly measuring the Breit-Wigner
resonant transition from o-Ps to p-Ps without the magnetic field.
At the same time, the width of the measured Breit-Wigner resonance
directly provides the lifetime of p-Ps. This measurement is the
first precise spectroscopic experiment involving the magnetic
dipole transition and high-power millimeter waves. The development
of a gyrotron and a Fabry-Perot cavity is described as providing an
effective power of over 20 kW, which is required to cause the
direct transition from o-Ps to p-Ps. Those values measured by the
newly developed millimeter wave device pave the way for examining
the discrepancy observed between conventional indirect experiments
on Ps-HFS and the theoretical predictions of Quantum
Electrodynamics.
It is my great pleasure to publish New Frontiers in
Lifestyle-Related Dis eases, the proceedings of the Showa
University International Symposium for Life Sciences, 3rd Annual
Meeting, held at Showa University on Sep tember 13, 2006. This
symposium was supported, in part, by Grants for the Promotion of
the Advancement of Education and Research in Graduate Schools and
Ordinary Expenses for Private Schools from the Ministry of
Education, Culture, Sports, Science, and Technology of Japan. On
behalf of Showa University, I would like to express my deepest
thanks to all the authors and editors for their great contribution
to the publication of this memorable book that accelerates research
activity in lifestyle-related diseases. Akiyoshi Hosoyamada, M.D.,

Preface The leading cause of death in Western countries and some
developing countries is atherosclerotic cardiovascular diseases.
Among them, acute myocardial infarction is the most common type of
fatal disease, caused by the progression of atherosclerosis
characterized by accumulation of choles terol in vascular walls.
Development of atherosclerosis is greatly enhanced by major risk
factors for cardiovascular diseases such as obesity, hyperlip
idemia, diabetes (hyperglycemia), and hypertension. Among those,
obesity frequently initiates a metabolic change that subsequently
induces hyperlip idemia, diabetes, hypertension, and eventually
atherosclerotic cardiovascu lar diseases. Because obesity and its
related disorders largely depend on lifestyle factors such as high
calorie intake and low physical activity, a series of disorders are
termed lifestyle-related diseases."
