INTEGRATING TECHNOLOGY AND TRADITIONAL SYSTEMS IN REGIONAL REVITALISATION; INSIGHTS FROM JAPANESE PRACTICES
This study examines the integration of Information and Communication Technology (ICT) solutions and advanced technology practices and their coexistence with conventional systems and initiatives that have been operating in different regions of Japan to address some of the socio-economic challenges. The methodological approach of the study includes three facets, namely government initiatives, technology involvement and local society actors. The study examines government visions and initiatives that emphasize the use of advanced technology as a key factor and tool to enable solutions and realize the target vision. The ageing population and economic stagnation are common challenges in different regions of Japan. The adaptation of technology and the integration of technological advances across sectors with an impact on productivity have been explored in the Vision Action Plans. With an ageing farming community, smart agriculture is one of the developments highlighted, as is the use of artificial intelligence and big data analytics, and autonomous systems in the image of the \u27smart city\u27 plan of a case study local government of Nago-city, in the southern prefecture of Okinawa. The study notes that Society 5.0 is seen as a blueprint for harnessing the potential of technological advances to address social and economic issues and build a more inclusive, sustainable and resilient society that balances economic growth with societal well-being and regional revitalizatio
New Constraints on Radiative Decay of Long-Lived Particles in Big Bang Nucleosynthesis with New He Photodisintegration Data
A recent measurement of He photodisintegration reactions,
He(,)H and He(,)He with laser-Compton
photons shows smaller cross sections than those estimated by other previous
experiments at MeV. We study big-bang nucleosynthesis
with the radiative particle decay using the new photodisintegration cross
sections of He as well as previous data. The sensitivity of the yields of
all light elements D, T, He, He, Li, Li and Be to the cross
sections is investigated. The change of the cross sections has an influence on
the non-thermal yields of D, He and He. On the other hand, the
non-thermal Li production is not sensitive to the change of the cross
sections at this low energy, since the non-thermal secondary synthesis of
Li needs energetic photons of MeV. The non-thermal
nucleosynthesis triggered by the radiative particle decay is one of candidates
of the production mechanism of Li observed in metal-poor halo stars
(MPHSs). In the parameter region of the radiative particle lifetime and the
emitted photon energy which satisfies the Li production above the abundance
level observed in MPHSs, the change of the photodisintegration cross sections
at MeV as measured in the recent experiment leads to
% reduction of resulting He abundance, whereas the Li
abundance does not change for this change of the cross sections of
He(,)H and He(,)He. The Li abundance,
however, could show a sizable change and therefore the future precise
measurement of the cross sections at high energy 50 MeV is
highly required.Comment: 10 pages, 7 figures, conclusion not changed, to be published in PR
Neutron capture and inelastic scattering cross sections for 186 Os, 187 Os, and 189 Os and the Re-Os chronology
We measured the neutron capture cross sections of 186,187,189Os taking for the first time their pulse height spectra for neutrons between 5 and 90 keV by means of an anti-Compton NaI(Tl) spectrometer. The neutron inelastic scattering cross section for 187Os as well as the neutron elastic scattering cross sections for 186,187Os were also observed with use of 6Li-glass scintillation detectors with a small systematic uncertainty.SCOPUS: cp.pinfo:eu-repo/semantics/publishe
The influence of beryllium on cell survival rates in theIn-vitro culture system, on intracellular DNA synthesis and on SRBC-IgM antibody production responses
Immunocytotoxicity of beryllium (Be) was evaluated by studying cell viability, intracellular DNA synthesis and SRBC-IgM response in an in-vitro culture system using non-sensitized spleen cells of a C57BL mouse. Be addition showed a suppressive effect on cell viability, an enhancing effect on DNA synthesis and on IgM antibody production. The suppressive effect on cell viability manifested itself markedly as the concentration of Be was increased or the culture time was prolonged. The DNA synthesis-enhancing effect was noted at a relatively low concentration of Be (not more than 10μM). The enhancing effect on the IgM response was related to Be concentration at not more than 20μM. The experimental results mentioned above speculate that the cytotoxicity of Be shows a conflicting pattern of enhancement or suppression according to the concentration used and that immunologically it has a modulating effect or an activating effect on the immunocompetent cells
