- Recently, with a spread of high definition video streaming services and ubiquitous network, development of high-quality, ultra-realistic and low-power display systems has been demanded. We have been studying physical properties of liquid crystal materials, precise control technique of polarization, high performance liquid crystal display (LCD) devices and its application to the advanced display systems for the realization of new media such as electric paper display and digital signage display, and low-energy society. We established a polarization control technology which realizes a precise control of polarization with liquid crystal materials. By using this world-leading technology, we have been studying the control of the surface alignment of liquid crystal molecules and developed a wide-viewing angle and fast switching liquid crystal display, ultra-high definition field-sequential-color display (Fig. 1), ultra-low power reflective full-color display (Fig. 2) and large-size high-quality display system.
- We are also studying the ultra-realistic display systems such as a spatial 3D display and a multiple directional viewing display based on the precise light control technique as a next generation interactive communication technologies (Fig.3). We hope to conduct collaborative research with a willing company for a practical application of this technology in industry.

- For 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.

- HIV infection is one of most serious concern in infectious diseases. We will perform anti-HIV assays for unmet medical needs in control of HIV infections with established novel assays. We have developed reverse transcriptase inhibitor that has novel mechanism of inhibition, translocation-inhibition (J Biol Chem, 2009). Dr Kodama participated in the primary screening and development of a new HIV integrase inhibitor, elvitegravir (J Virol 2009), and a unique reverse transcriptase inhibitor, islatravir, which phase III clinical trials by the Merck & Co., Inc. will complete, soon. We have a representative resistant HIV strain-library for anti-HIV screening and several target oriented high through-put screening systems.

- 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.

- The present invention relates to a technique for differentiating iPS cells into target differentiated cells while suppressing tumorigenesis in the iPS cells. In use of a statin and a differentiation inducer, iPS cells are differentiated into target differentiated cells, whereby iPS cells can be differentiated into differentiated cells in which tumorigenesis is suppressed.

- The global pandemic is forcing democracies around the world to hold non-contact elections. Internet voting is considered a viable option, but there is little chance of introducing it in Japan. Similarly, while there is an urgent need to implement online parliament to reduce the risk of infection, only a minority of parliaments are willing to do so. In this study, we will identify the factors that hinder the digitalization of democracy and pursue the possibility of social implementation in Japan.

- Losing 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. We have developed an LC/ESI-MS/MS method using fragment patterns characteristic of conjugation types for group-specific and comprehensive analysis of conjugated cholesterol metabolites. This method can contribute for an efficient discovery of diagnostic marker candidates toward various diseases.

- A new dry-contact technique for transduction of broadband, high-frequency ultrasound via a solid layer inserted between water and the sample, whereat the pressure of about 0.1 MPa is applied at the layer/sample interface by evacuating air between them, has been developed. Based on the technique, acoustic imaging of an electronic package is realized under the dry environment (Fig. 1). Typically, the polymer films are used as the intermediate layer for water protection of the sample, and by utilizing the acoustic resonance phenomenon among water, film and the sample, higher quality acoustic image of the testing sample than that for the water immersion case can be recorded without getting the sample wet (Fig. 2). Moreover, thin materials, e.g., polymer film (Fig. 3), etc. can be characterized by analyzing the acoustic resonance phenomenon among the three media. We hope to conduct collaborative research with a willing company for a practical application of this technology in industry.
