[LC/ESI-MS/MS]
Discovery of diagnostic markers by metabolomicsFeaturesLosing cholesterol homeostasis with inborn errors of metabolisms or hepatobiliary diseases makes a change to in vivo cholesterol metabolism profile and causes the emergence of increased metabolites as conjugates in blood and urine.

[LED]
Lethal effects of blue light on insectsFeaturesWe revealed the strong lethal effect of short-wavelength visible light (blue light: 400–500 nm) on insects. That is, we found that blue light irradiation by using a common light-emitting diode (LED) can kill the eggs, larvae, pupae, and adults of various orders of insects. Our findings will provide clean and safe pest-control technique as well as important information on the hazards of exposure to visible light.

[Life Cycle Analysis]
Visualization of supply chain risks from the resource logistics perspectiveFeaturesWith the increased global concerns of resource and environmental constraints of recent years, the role of mining, as a constituent of social responsibility associated with resource extraction and usage, is becoming increasingly important in the science, technology, and innovation policy. Under increasing public and shareholders' concerns of social and environmental sustainability, the fabrication industries require careful attention owing to their own risks related to the resources and materials that are used in their products and services. The Material Flow Analysis tool and Input output technique provide useful perspectives and valuable evidences for avoiding or minimizing the social and environmental risks related to the demand of resources. Targeted Application(s)/IndustryOur developed model evaluates the risk weighted flow analysis by combining the resource logistics database and Global Link Input Output model. The estimated results shed light on how resource logistics prepares policy makers and R&D engineers to confront the risks behind resource usage and how the information should be shared among the stakeholders.

[language]
A Comparative Semantic Analysis of English and JapaneseFeaturesWhen 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)/IndustryThe 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. Graduate School of International Cultural Studies

Universal Design in Language UseFeaturesMy 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. Targeted Application(s)/IndustryAlthough I am conducting basic research, I believe it helps develop effective language teaching/learning methods, rehabilitation programs for aphasia, and so on. |

[licorice]
Development of disease-resistance animals by animal breeding method and dietary additiveFeaturesThe most important disease in domestic and foreign pig industry is the pig respiratory disease complex (PRDC) that the pigs show the respiratory trouble by the infection of two or more pathogens. Pigs were selected for low direction of mycoplasma pneumonia (MPS) lesion for fifth generation in a joint research with Miyagi Prefecture Livestock Experiment Station. As a result, the lesion of MPS was decreased, a natural immunity (phagocyte activity; PA, the ratio of granular leukocyte to lymphocyte; GLR) and cellular immunity increased and SRBC specific antibody production (AP) was controlled. Dietary addition of seaweed and licorice enhanced the immune function in the peripheral blood and mucosa in swine. Furthermore, dietary addition of licorice induced the enhancement of mucosal immunity and anti-inflammation effect in the peripheral tissues. These naturally derived products are useful for the reduction of dietary addition of antibiotics in the pig industry. In addition, we selected for the natural immunity, the acquired immunity, and both of the mice during 20th generation, and the immunogenic property and disease resistance of these mice were investigating. We hope to conduct collaborative research with a willing company for a practical application of this technology in industry. Graduate School of Agricultural Science
