[slip]
Development of Fall-Prevention Footwear Based on Mechanical Analysis of Slip-Related FallsFeaturesThe number of fatalities due to falling accidents indoor/outdoor has increased in Japan as well as in other advanced countries. The fatalities due to falling accidents in a year have exceeded those due to traffic accidents in Japan recently. Because more than 80% of the fatalities are elderly people, it is considered an urgent issue to prevent their falling. We have conducted researches on falling during walking due to induced slip, in the contact interface of shoe sole and floor, through tribological and biomechanical approaches. We clarified the required values of static friction coefficient (figure 1), between shoe sole and floor, and how to gait to prevent slipping through kinetic analysis of gait. We also succeeded in the development of a unique footwear outsole having the high-grip property (figure 2) and high slip-resistant concrete pavement blocks (figure 3) through the collaboration with regional companies. We have recently conducted research and development of footwear that is able to prevent falls due to balance loss after slipping. Targeted Application(s)/IndustryProducts for fall prevention in daily life or in work site. Evaluation of slip resistance of footwear and floor materials. |

Drug Development for Fundamental Treatment of Alzheimer's DiseaseFeaturesBackground: Alzheimer's disease (AD) is a neurodegenerative disorder with a large unmet medical need. Recently, our pilot clinical study suggested the possibility that 1-year oral administration of decocted nobiletin-rich Citrus reticulata peel could be of benefit for improving the cognition of patients with AD, with the following pharmacological features: 1) this Kampo medicine includes a large amount of nobiletin that can rescue the memory impairment and prevents hippocampal amyloid beta accumulation in APP-Tg mice, as originally reported by us, and 2) the medicine reversed impaired learning and memory to a greater degree than nobiletin in animal, to which sinensetin, another constituent contributes in large part. Targeted Application(s)/IndustryOur research goal is discovery of the drugs for fundamental treatment of AD. I hope to conduct collaborative research with a willing company for a practical application of this technology in industry. Department of Pharmacotherapy, Graduate School of Pharmaceutical Sciences

[Smartphone]
Message Transmission without Cellular Coverage, “Relay-by-Smartphone"FeaturesOur technology provides the necessary method for sending messages even when the physical infrastructure is not available. The technology utilizes common smartphone WiFi functionality to send message in a multi-hop fashion. Thus it is possible to send message to people further away. Our technology has been designed to be based on Delay-Tolerant Networks (DTN), but the technical key idea is the combination of DTN and Mobile Adhoc Network (MANET), which can improve the message delivery in an area with high population density or where mobility are fixed such as evacuation center. Targeted Application(s)/IndustryThis technology can be used to distribute information during emergency situation such as after disaster. In addition, it is possible to provide additional services such as advertisement within shopping areas, distribution of coupons, exchange of information within small group during public events or uses as transceiver during group hiking. There is also possibility of using this technology to provide communications service in developing nations. |

Low-Temperature Synthesis of SiC Porous Bulk by Using NaFeaturesSiC ceramics is generally prepared at high temperature of 1200–2000ºC. We are able to prepare SiC at around 700ºC by using Na. Nano-powder of beta-type SiC was obtained from a mixture of Si and carbon powders in a Na melt. SiC porous ceramics were synthesized by heating mixtures of Si powder and carbon black at 700–900ºC in Na vapor. Biomorphic cellular SiC ceramics were formed by heating carbonized woods at 700 ºC with a Na-Si melt. Targeted Application(s)/IndustryApplications : SiC porous ceramics are used in a wide range of applications, such as filters for gas or molten metal, diesel particle filters, catalysis supports, and light-weight structural materials.

Development of the method of Baby Borehole Hydraulic Fracturing, BABHYFeaturesFor the effective measurement of the reopening pressure in hydraulic fracturing, it is necessary to use the testing equipment with sufficiently small compliance. This limitation makes it difficult to apply the hydraulic fracturing for the measurement of the maximum stress, because the compliance of conventional equipments is generally so large. Taking account of this situation, we proposed a new concept which allows us to do the in-situ tests of hydraulic fracturing for stress measurement at so deep depths as more than 1 km. We call the concept the Baby Borehole Hydrofracturing, BABHY for short. In order to put the new concept into practice, we developed the BABHY sonde and finally we succeeded to carry out hydraulic fracturing test by using the tools in a vertical borehole of 811 m depth. We hope to conduct collaborative research with a willing company for a practical application of this technology in industry.

[Soil Improvement]
Development of Recycling Technology for High-Water Content Sludge by Using Fiber MaterialsFeaturesThe recycling rate of construction muds and sludge is very low because the water content of these muds is very high and direct reuse of them is very difficult. Therefore, a new recycling technology for high-water content sludge has been developed in this laboratory. This technology is called "Fiber-Cement-Stabilized Soil Method", and it uses fiber materials and cement. The main feature of this method is to mix the fiber materials with the sludge, and the fiber materials included in the soil produce several geotechnical merits. Targeted Application(s)/IndustryThe modified soils produced by this method can be used as ground materials for reinforced embankment of the river bank and soil structures because they have several features such as high failure strength, high failure strain high durability for drying and wetting and high dynamic strength.
