A Shrinking Society

Post-Demographic Transition in Japan

By: Toshihiko Hara

This is the book to focus on a new phenomenon emerging in the twenty-first century: the rapidly aging and decreasing population of a well-developed country, namely, Japan. The meaning of this phenomenon has been successfully clarified as the possible historical consequence of the demographic transition from high birth and death rates to low ones. Japan has entered the post-demographic transitional phase and will be the fastest-shrinking society in the world, leading other Asian countries that are experiencing the same drastic changes. The author used the historical statistics, compiled by the Statistic Bureau, Ministry of Internal Affairs and Communications in 2006 and population projections for released in 2012 by the National Institute of Population and Social Security Research, to show the past and future development of the dependency ratio from 1891 to 2060. Then, utilizing the population life table and net reproduction rate, the effects of increasing life expectancy and declining fertility on the dependency ratio were observed separately. Finally, the historical relationships among women’s survival rates at reproductive age, the theoretical fertility rate to maintain the replacement level and the recorded total fertility rate (TFR) were analyzed. Historical observation showed TFR adapting to the theoretical level of fertility with a certain time lag and corresponding to women’s survival rates at reproductive age. Women’s increasing lifespan and survival rates could have influenced decision making to minimize the risk of childbearing. Even if the theoretical fertility rate meets the replacement level, women’s views of minimizing the risk may remain unchanged because for women the cost–benefit imbalance in childbearing is still too high in Japan. Based on the findings, the author discusses the sustainability of Japanese society in relation to national finances, social security reform, family policies, immigration policies and community polices.

An Essay on the Principle of Sustainable Population

By: Toshihiko Hara

This book focuses on the future of the global population and proposes revising Malthus’ Law. The United Nations estimates that the global population will top 11 billion by 2100, at which point its growth will be near an end: it will find a new ‎equilibrium in a long demographic transition from high birth and death rates to low ones. However, the author reviews the fertility developments reported in the World Population Prospects 2017, which are near or below the replacement level in most regions, with the important exception of Sub-Saharan Africa, and warns of a possible scenario of the extinction of human society. Returning to Malthus, his Essay on the Principle of Population is critically reconsidered. Simple simulations show that exponential growth and decay are unsustainable beyond the narrow ranges of the net reproduction rate. In addition, the length of reproduction periods, which depends on women’s lifespans, plays a pivotal role. The limits of growth are given in any case, to the extent that time and space will permit. From this perspective, teleological conditions such as instinct, passion, or even natural reproductive tendencies are irrelevant and unnecessary. When the population deviates too far from the replacement level, either its shrinking or massive growth will overshoot the limits of its existence. This principle of sustainable population indicates that the demographic transition must follow a logistic curve. Using a system dynamics approach, the author constructs a simulation model based on four major loops: fertility, reproduction timing, social capital accumulation, and lifespan. Using only endogenous variables, this model successfully reproduces the historical process of the demographic transition in Japan. Thereby, it shows that the timing and periods of reproduction, maximum fertility, and maximum lifespan hold the key to sustainability. Based on these findings, the author subsequently discusses recovering replacement fertility, extending lifespans, and the demographic future of the human race.

HPLC

A Practical Guide

By: Toshihiko T Hanai

How can these compounds be separated? Why was that method used? These are the two basic questions often asked by students of chromatography. HPLC: A Practical Guide provides the answers, enabling the reader to grasp the concepts of the technique using simple, representative chromatograms. Divided into six chapters, this practical guide covers basic concepts of HPLC; instrumentation; stationary phase materials; eluents; column efficiency; and the influence of physical chemistry on separations. Focusing on the basic considerations such as selection of stationary phase and eluent, rather than specific applications, sections on troubleshooting are also included. Uniquely, the descriptions of chromatographic separations are based on solubility using molecular properties, and solubility parameters are used to analyse the selections of chromatographic mode and column. Presenting the chemistry of liquid chromatography for undergraduate students, this valuable practical guide will also be useful for laboratory staff in industry and academia.

Quantitative In Silico Chromatography

Computational Modelling of Molecular Interactions

By: Toshihiko Hanai

The coupling of mass spectrometry or nuclear magnetic resonance to chromatography has broadened the possibilities for determining organic reaction mechanisms. And while many results have been published reporting these, even more can be achieved through modern computational methods. Combining computational and theoretical techniques with advanced chromatographic methods offers a powerful tool for quantitatively determining molecular interactions . This book presents the possibilities for characterising biological applications by combining analytical and computational chemistries. Written by the author of “HPLC: A Practical Guide” (RSC, 1999), the book examines not only the behaviour of biological reactions per se, but also describes the behaviour of biological molecules in chromatography systems. Various software packages are reviewed, and most computations can be performed on a standard PC using accessible software. Consideration is given to a variety of chromatographic techniques and strategies for high-sensitivity detection are presented. The first book of its kind, it will inspire readers to explore the possibilities of combining these techniques in their own work, whether at an industrial or academic level.

Advances in Liquid Chromatography

35 Years of Column Liquid Chromatography in Japan

By: Toshihiko Hanai,Hiroyuki Hatano

This book is a contemporary review of selected subjects in liquid chromatography, especially of the technical development, rather than the applications. The subjects are focused in the biomedical and environmental fields. This is also a troubleshooting record. Complex analytical problems such as sensitivity (sensitive detection by chemiluminescence, coulometric detection, laser based detection, necessity of degassing the system for sensitive detection), difficulty (free radical detection by Electron Spin Resonance, Polarimeter for chiral recognition) and reproducibility (packings for chiral separation and stable bonded silica gels) are solved. Theoretically and environmentally important miniaturizations are described. Individual chapters written by specialists provide information beyond what can be found in general textbooks of liquid chromatography.

Tundish Technology for Clean Steel Production

By: Yogeshwar Sahai (Ph. D.),Toshihiko Emi

Continuous casting of steel has become a widely used process and an important step in steel production. The worldwide share of continuously cast steel has increased significantly in the last 25 years or so. However, concurrent with this increase in production levels are stringent quality requirements that have become crucial in the face of progressively increasing machine throughputs and larger product dimensions. As a result, steel cleanliness and strict composition control are now the primary concern of steelmakers.The tundish is the last metallurgical vessel through which molten metal flows before solidifying in the continuous casting mold. During the transfer of metal through the tundish, molten steel interacts with refractories, slag, and the atmosphere. Thus, the proper design and operation of a tundish are important for delivering steel of strict composition and quality. This pioneering book is the first of its kind to cover all aspects of tundish technology, ranging from fundamental aspects and theory necessary for understanding the basic concepts of tundish operations to operational aspects of the tundish. Written by internationally recognized experts in continuous casting technology in general and tundish technology in particular, this book is sufficiently fundamental to serve as a graduate-level textbook on process metallurgy or as an important reference for metallurgical researchers; at the same time, it is comprehensive enough to contribute to the understanding of scientists and engineers engaged in research and development in the steel industry.

Optical Fiber Telecommunications VIB

Chapter 7. Extremely Higher-Order Modulation Formats

By: Masataka Nakazawa,Toshihiko Hirooka,Masato Yoshida,Keisuke Kasai

We provide on overview of fundamental technologies and recent challenges on extremely higher-order quadrature amplitude modulation (QAM) such as 256–1024 levels, toward the realization of an ultrahigh spectral efficiency approaching the Shannon limit. Key components required for such a higher-order QAM transmission are described in detail, including a coherent light source, an optical phase-locked loop, an IQ modulator, and a digital demodulator. We also present recent demonstrations of single-carrier 1024 QAM, 256 QAM-OFDM, and OTDM-RZ/32 QAM transmissions realized with these fundamental technologies.

Diagnostic Imaging of the Liver Biliary Tract and Pancreas

Data Analysis and Diagnostic Procedures

By: Sadayuki Sakuma,Takeo Ishigaki,Toshihiko Takeuchi

The development and the widespread clinical application of various di agnostic imaging modalities, such as diagnostic ultrasonography, X-ray computed tomography, single photon emission computed tomography, and magnetic resonance imaging, have been beyond all expectation. In particular, ultrasonography and X-ray computed tomography have be come major diagnostic tools for diseases of the liver, the biliary tract, and the pancreas. They often have virtually replaced other conventional imag ing modalities including invasive angiography and percutaneous trans he patic cholangiography. One modality may complement or conflict with another or other modalities. Each modality should be carefully selected with due regard for its diagnostic efficacy. In this book, the first section contains nine chapters dealing with current techniques of each diagnostic modality applicable to the liver, the biliary tract, and the pancreas. The second section deals with diseases of the liver, the biliary tract, and the pancreas and takes the form of case presentation with discussion of the significance of diagnostic imagings and diagnostic procedure. Preparation of the manuscript was made possible by the help of Dr. S. Fujita, who prepared the photographs, and Mrs. Sobajima, who typed the original manuscript. Dr. S. Miura and Miss Y. Shimizu under took the labor of translating our manuscript from Japanese into English. I would like to express my deep appreciation to all these persons, as well as to the contributors to this book, and also to the publishers, Shujunsha, Japan and Springer-Verlag.
