The NIJL has developed variety kinds of databases, i.e., catalogue databases, image databases, movie databases, and full text databases. As these systems have been developed under different backgrounds, users have to learn different command for each database. Furthermore, although some databases have similar contents, users cannot access related information unless they understand NIJL database ...

Purpose of Review Since healthcare costs have continued to rise, health-economic approaches in perioperative medicine tend to create potential benefits. However, a review of the perioperative literature reveals that there are only few published economic analyses. The aim of the present review is to explore the health-economic researches in the field of perioperative medicine. Recent Findings In...

This paper proposes a novel dc-dc converter called the dc-dc multilevel voltage multiplier (mvm). In general, an nx mvm can be built by using two switches, 2n-2 diodes and 2n-2 capacitors, free of magnetic components. It is based on the multilevel converters principle and designed for unidirectional power transfer applications. Each device blocks one voltage level, therefore high voltage conver...

One of the most important breakthroughs in modern biology was discovering that double chain small or large RNA molecules are able to regulate gene expression. Formerly it was thought RNAs have just two broad functions in cells: Single-stranded messenger RNAs (mRNAs) are vital intermediaries in gene expression, transmitting information between DNA and protein. Ribosomal and transfer RNAs have st...

My research interest is to solve problems from mathematics and physics with simple and clean ideas, and along the way to learn and to find new mathematical structures and theories. Localization techniques in various settings, combining with various subjects of mathematics, have played central roles in my researches. See my ICM lecture [38] for more detailed discussions. I divide my past researc...

Titanium is an ideal material for use in prosthodontics because of its biocompatibility, corrosion resistance, and mechanical strength combined with its lightweight. Recently the use of titanium and titanium alloys for fixed restorations has increased substantially, mainly due to the improvement of techniques for the casting titanium and its alloys. This article reviewed the studies on titanium...
