Universal Design in Language Use

 
 
NEXT
PREV
概要

My current research topic is "universal design in language use," with special reference to order in language and thought. In particular, I am investigating (1) similarities and differences in neural processing of languages with different basic word orders, (2) to what extent the order in non-verbal thought is affected by the order in language, and vice versa, and (3) what is the optimal order in human language and human thought, if any.

従来技術との比較

Many studies have reported that subject-object (SO) word order, where the subject (S) precedes the object (O), tends to have lower processing costs and is preferred by native speakers compared to object-subject (OS) word order. However, traditional studies have primarily focused on SO languages, such as Japanese and English, where SO word order is the grammatical default. As a result, it remains unclear whether the preference for SO word order reflects the basic word order of individual languages or more universal cognitive characteristics of humans.

特徴・独自性
  • To address this, we are conducting research on the cognitive processing of minority languages that use object-subject (OS) word order as their basic word order—specifically Kaqchikel and Truku, which have not been studied before. This research focuses on the relationship between “word order in language” and “order of thought.” The findings are then compared to the cognitive processing of Japanese and English.
  • For this purpose, experimental equipment is brought to the speakers’ regions (Guatemala and Taiwan) to conduct a variety of investigations and experiments, including behavioral experiments, eye-tracking, and brain function measurements. Additionally, for experiments requiring large, non-portable equipment such as MRI scanners, the speakers are invited to Japan for the studies.
実用化イメージ

Although I am conducting basic research, I believe it helps develop (1) effective language teaching/learning methods, (2) rehabilitation programs for aphasia, (3) dynamic preservation of endangered languages/dialects, and so on.

Creation of a high functional bio-interface using laser fabrication

 
NEXT
PREV
特徴・独自性
  • 　Using laser fabrication, we are developing techniques to enhance material surface properties and functionality. For example, to create a functional interface, we aim to clarify, by way of simulation and experimentation, the phenomenon that occurs when the surface of a material is irradiated using a laser beam.
  • 　We expect that the results of our research will be widely applicable, including biomedical devices.
  • ■　Creation of biocompatible surfaces
  • 　Materials used for artificial organs, vessels, and other bio-implants require excellent tissue and cell biocompatibility. Therefore, we are exploring the creation of biocompatible surfaces using a new laser irradiation process in this study.
  • 　We have succeeded in imparting a biologically active function to titanium-based materials by applying the laser irradiation technique. When such a material that has a biologically active function is inserted in a living body, hydroxyapatite (the principal constituent of bones and teeth) precipitates on the surface. Using the laser irradiation technique, we can manufacture bone-adherent implants, and we envisage their application to artificial joints or dental implants.
  • 　This research aims to discover such breakthrough solutions for biomedical applications using the laser irradiation technique.

Optimizing everything / Optimal Society

 
 
 
NEXT
PREV
特徴・独自性
  • Aiming at developing practical quantum optimization technology known as quantum annealing, we are working on exploring basic technologies that can overcome the limitations and applications in collaboration with multiple companies. The advantage of the method is that it can be used simply by formulating a cost function that draws the goal to be optimized once, but we are not limited to the original method. We extend it by considering a much easier problem, sequential optimization by learning, black box optimization, etc.. In particular, it is being applied to automated driving, logistics in factories, and evacuation guidance during disasters.
実用化イメージ

Applications to route search problems such as automatic driving of various vehicles, evacuation route guidance at the time of disaster, process scheduling and a large number of combination problems. We can provide a solution to combinatorial optimization in each industry. (Transportation / distribution, manufacturing, materials, drug discovery, etc.)
