In Japan, focal cities experience a number of probtems retated to deterioration of residentiat environment, quality of public service, and vitalization of commercial rand. SpecificaLLy, the presence of Large vacant tots behind sizable stores, office buildings, hospitals, and factories devitatize urban activity and its Landscape. Many local cities are seeking to actuatize a sustainable compact city with an integrated poputation, commerce, traffic and other pubLic services in ways that promote a tow carbon and energy-conserving society. Against the backdrop of these issues, this study examines the occurrence of large vacant lots and their utilization by tocat governments in Japan based on a questionnaire and fietd survey. It highlights severat cases in which a Large vacant tot is used to forward the development of a compact city by a tocat government.

BACKGROUND: Living donor liver transplantation (LDLT) has been increasingly used to treat hepatic tumors worldwide in recent years, and is currently the most effective alternative to deceased donor liver transplantation to overcome the problem of organ shortage. LDLT has played an enormous role in treating early malignant hepatic tumors. But the indication of LDLT for malignant hepatic tumors is based on indefinite criteria. This review summarizes the recent studies in LDLT for treating malignant hepatic tumors. DATA SOURCES: A literature research of the PubMed database was conducted and research articles were reviewed. RESULTS: The current data on LDLT for malignant hepatic tumors, combined with our hospital experience, indicated that if a patient with hepatocellular carcinoma (HCC) who meets with the conventional Milan criteria cannot undergo tumor resection because of poorly preserved liver function, and a cadaveric graft is difficult to obtain within six months, LDLT may be selected. In a patient with recurrence of HCC after conventional therapies, feasibility, optimal timing, and efficacy of LDLT as a second-line treatment should be determined. CONCLUSIONS: Tumor recurrence is related to the biological behavior and staging of the tumor. New immunosuppressors which have anti-tumor effects and inhibit the immune system need to be developed. The indications of LDLT for hepatic malignant tumors should be selected meticulously.

A reduction of environmental burdens is currently required. In particular, proposing a new approach for the construction of a smart city using renewable energy is important. The technological development of a smart city is founded building equipment and infrastructure. However, planning methods and their techniques using the collaboration approach with residents are only just developing. This study aimed to develop a support tool for the construction of a smart city using renewable energy while facilitating consensus-building efforts among residents using the method for a cooperative housing development. We organized the supporting methods for the construction of residential area using the cooperative method. Then, we developed supporting toots that interface the computer with these methods. We examined the support techniques for the construction of a residential area using renewable energy technology by analyzing Japanese cases of a smart city. Moreover, we developed a support toot for the construction of a smart city on a trial basis. We integrated the smart city construction toots and the cooperative housing construction support tool. This tool has a 3D modeling system that helps residents to easily understand the space image as a result of the examination. We also developed a professional supporting toot that residents can consider for cost-effectiveness in renewable energy and its environmental toad reduction rate for the planning of a smart city.

The magneto-transport properties of （111）-oriented single-crystal thin films of SnTe were investigated. SnTe （111） thin films were epitaxially grown on a BaF2 substrate by molecular beam epitaxy. By optimizing the growth conditions and the thickness of the films, the bulk carrier density could be reduced, making it possible to detect the surface transport. Magneto-conductance （MC） measurements show a cusp-like feature around zero magnetic field, which is attributed to the weak-antilocalization effect of the transport in the topological surface state. Detailed analysis of this negative MC reveals a reduced number of transport channels contributing to the surface transport, suggesting strong coupling between Dirac valleys on the SnTe （111） surface, as a characteristic feature of the transport in the multivalley structure of topological crystalline insulators.

It has been thought that granitic crust, having been formed on the surface, must have survived through the Earth＇s evolution because of its buoyancy. At subduction zones continental crust is predominantly created by arc magmatism and is returned to the mantle via sediment subduction, subduction erosion, and continental subduction. Granitic rocks, the major constituent of the continental crust, are lighter than the mantle at depths shallower than 270 km, but we show here, based on first principles calcu- lations, that beneath 270 km they have negative buoyancy compared to the surrounding material in the upper mantle and transition zone, and thus can be subducted in the depth range of 270-660 km. This suggests that there can be two reservoirs of granitic material in the Earth, one on the surface and the other at the base of the mantle transition zone （MTZ）. The accumulated volume of subducted granitic material at the base of the MTZ might amount to about six times the present volume of the continental crust. Our calculations also show that the seismic velocities of granitic material in the depth range from 270 to 660 km are faster than those of the surrounding mantle. This could explain the anomalous seismic-wave velocities observed around 660 km depth. The observed seismic scatterers and reported splitting of the 660 km discontinuity could be due to jadeite dissociation, chemical discontinuities between granitic material and the surrounding mantle, or a combination thereof.

Sustainable sanitation is an approach for more ecological and sustainable water resources management. In this paper, we proposed one of the new integrated waste treatment systems： an ＂sustainable sanitation system＂ that includes separation of the black water from water system by a non-flushing toilet （bio-toilet）, and a gray water treatment based on a biological and ecological concept. Sustainable sanitation system also converts the domestic waste to soil conditioners and fertilizers, for farmland use. As one of the case studies, Environmentally Symbiotic Housing in which people actually live using the bio-toilet for the black water treatment and the household wastewater treatment facility for the gray water was introduced. The availability of this system was investigated by analyzing the sawdust used in the bio-toilet and the quality of the effluent in the household wastewater treatment facility. As the result, the water content of the sawdust did not exceed 60% in any of the sampling points and the BOD and COD of the effluent of the household wastewater treatment facility were below 10 and 20 mg/L respectively, due to the low loading. Compared to the pollution load on the water environment created by the conventional system, it was found that the effluent of the house has a lower load than the tertiary treatment and the volume of the water consumption is 75% of the conventional system.
