[Japanese]

A Comparative Semantic Analysis of English and Japanese

NEXT
PREV
Features

When people communicate with each other through language, what mechanisms are there to convey meanings? Do the mechanisms vary from language to language, or are they the same across languages? These are the questions to which I am seeking answers through my research on English and Japanese. Sometimes one word can express several different meanings. For example, if you say "There is a newspaper on the table", "newspaper" denotes a printed matter, whereas if you say "The newspaper denounced the injustice", the same word denotes the media. The coexistence of multiple possible meanings for a single word or phrase is called polysemy. I am interested in how people produce and understand words with many different meanings in actual communication.

Targeted Application(s)/Industry

The outcome of my research will bring better understanding of polysemy and contribute to the foundation of language processing and automatic translation, and to construction of lexicons (dictionaries) that are used for those purposes. It will also make contribution to the development of materials and methods in foreign language teaching/learning.

[Japanese diet ]

Development of healthy longevity meal and health supplement based on the Japanese diet

NEXT
PREV
Features

We studied the health function of the Japanese diet, and clarified that the Japanese diet from 1975 has the function of reducing stress, obesity, diabetes, fatty liver, dementia, cancer, and aging speed. And, with various evaluation systems, we clarified the characteristics of 1975 Japanese diet (Fig.1). The various findings obtained in this research are a considerable advantage in developing health foods, which helps to develop healthy longevity meals and health supplements.

Targeted Application(s)/Industry

In addition to research on functionality of foods, the identification of functional ingredients by simultaneous analysis of meals and ingredients (Fig.2) and the identification of ingredients that improve the balance of intestinal flora better (Fig.3) are also possible.

[Japanese natural history]

Exploring the change in fauna and flora from the results of the natural history of Tokugawa Japan

NEXT
PREV
Features

The natural history as nomenclature and description flourished in the 18th and early 19th century in Western countries, while in Japan as an exception in non-Western world, a characteristic description system was developed in the same period. And thus vast information concerning the flora and fauna in Japan was collected and organized. We are to make use of the results of the natural history of Tokugawa Japan for the diachronic environmental Studies. Especially as for indicator species we extract and reclassify the reliable materials from the literature and documents of Edo era from the perspective of the current taxonomy. And we compare them carefully with the scientific achievements after Meiji era aiming to point out the environmental changes in Japan and its surrounding areas. For example, the drastic changes in some geese populations wintering in Japan correlate strongly with the damages to the environment given by the developments in Far Eastern Siberia by the Russian Empire and in the Kuril Islands by Japan. We are prepared to provide academic consultations to corporations interested in our research.

[Joint reseach]

Surface scientific approach for developments in fuel cell's catalysts

NEXT
PREV
Features

From catalytic perspective, molecular-level understanding of surface phenomena occurring at nano-sized metal (alloy) particle surfaces is a key for developing highly active and durable catalysts. Our experimental approach for studying catalysis is preparations of well-defined metals or alloy surfaces by using ultra-high vacuum (UHV) and molecular-beam-epitaxy (MBE) techniques. We routinely use UHV-MBE, surface vibrational spectroscopy (IR, Raman), scanning probe microscopy (SPM), electron spectroscopy (XPS), electrochemical (EC) voltammetry, gas-chromatography (GC) etc., and try to clarify the solid surface phenomena on atomic, molecular-levels. We believe our research results directly link to future eco-friendly society.

[Joule heat]

Joule Heat Welding of Ultrathin Metallic Wires and its Application for Producing Functionality

NEXT
PREV
Features

For producing a new functionality from metallic micro and nano matarials, the welding and cutting technologies for small scale materials utilizing Joule heat has been developed (Fig. 1). A constant direct current is supplied to the system, where the free ends of two metallic wires are contacted, and the ends are successfully welded together in self-completed manner. This technology is also useful for manipulating a small scale materials.

Targeted Application(s)/Industry

Joule heat welding technology enables us to produce the functional elements on the electrode chips, e.g., a free-standing micro-ring and very-thin thermoelectric element (Fig. 2). Moreover, we have developed the technique for characterizing the physical properties of small scale materials (Fig. 3). We hope to conduct collaborative research with a willing company for a practical application of this technology in industry.

Development of Wearable Motion Measurement System for Motor Rehabilitation and Healthcare

NEXT
PREV
Features

In order to realize wealthy and vibrant local communities, it is desired that people in the community are healthy. However, the amount of the daily activity decreases as they get older, which increases the risks of the fall by weakened lower limb muscles and of the cerebrovascular disease, and so on. Therefore, for the elderly people, there is increased need of the walking training and the movement assistance in daily life, and of the rehabilitation aid.
In this study, focusing on the motor function of the lower limbs that is important for independent activities of daily living and that relates to the health maintenance, development of assistive technologies for decreased gait ability or for dysfunction of lower limbs are performed based on the technologies of electronics and signal processing. Especially, the wearable sensor system using gyroscopes and accelerometers are developed to measure kinetic information, and then the evaluation system for the gait ability and the lower limbs motor function is developed in this study.

Targeted Application(s)/Industry

The goal of this study is to realize simple and convenient measurement and accumulation of various information of gait, to visualize the obtained data for determination of training effect and evaluation of motor function, and to provide appropriate training program for each subject.
