Using Okayama City and Central Tokyo as representative case studies of regional and metropolitan areas in Japan, this study examines the impact of the evaluation of the 'hard' and 'soft' attributes of rail and bus services on the overall evaluation. This study then explores the relationship between the overall evaluation and usage frequency of rail and bus services, as well as the relationship between the usage frequency and travel-based CO2 emissions from private transport modes. Furthermore, this study investigates whether the emissions cause differences in the evaluation of the 'hard' and 'soft' attributes of public transport services. The findings suggest prioritising an improvement in 'hard' rather than 'soft' attributes in order to reduce emissions through the use of public transport in regional areas. However, in metropolitan areas, no relationship was found between the evaluation of public transport services and emissions, presumably because of the lower ownership rate of private cars that residents can use freely and the markedly higher level of rail and bus services. This study provides a methodological reference for analysing the potential to reduce travel-based emissions from private transport modes by enhancing public transport service contents. en-copyright= kn-copyright= en-aut-name=PradhanShreyas en-aut-sei=Pradhan en-aut-mei=Shreyas kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UjiharaTakehito en-aut-sei=Ujihara en-aut-mei=Takehito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HashimotoSeiji en-aut-sei=Hashimoto en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=CO2 emissions kn-keyword=CO2 emissions en-keyword=public transport kn-keyword=public transport en-keyword=evaluation kn-keyword=evaluation en-keyword='hard' and 'soft' attributes kn-keyword='hard' and 'soft' attributes en-keyword=usage frequency kn-keyword=usage frequency en-keyword=private transport modes kn-keyword=private transport modes END start-ver=1.4 cd-journal=joma no-vol=7 cd-vols= no-issue=1 article-no= start-page=1 end-page=7 dt-received= dt-revised= dt-accepted= dt-pub-year=2007 dt-pub=20070310 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The Lectures on the Development of Teaching Plans and Teaching Materials Tried in the Science Education Class in Master's Course, Okayama University kn-title=岡山大学大学院理科教育専攻で行った教材・授業案開発講義の試み en-subtitle= kn-subtitle= en-abstract=This is a report of the new type of lectures on the development of teaching plans and teaching materials attempted in the science class in the Master's Course, Okayama University.

In order to overcome these difficulties, we have developed some numerical methods and applied them to simple cases. As for stationary states, the finite element method provides us with sufficient geometrical freedom. Combined with the Kohn-Sham equation based on the density functional theory, this method virtually satisfies our requirement. In order to investigate time-dependent phenomena, we apply the time-dependent Kohn-Sham equation. Adopting the finite difference method, we are able to follow the development of quantum many-body system. As an example, we estimate the effects of the potential height, the electric field, and many-body interactions in some transition processes in quantum wells coupled by a tunneling barrier. This example is important in itself in relation to semiconductor superlattices and also serves as a benchmark for quantum simulations, variety of geometry corresponding to that of classical particles. en-copyright= kn-copyright= en-aut-name=TotsujiHiroo en-aut-sei=Totsuji en-aut-mei=Hiroo kn-aut-name=東辻浩夫 kn-aut-sei=東辻 kn-aut-mei=浩夫 aut-affil-num=1 ORCID= en-aut-name=HashimotoSeiji en-aut-sei=Hashimoto en-aut-mei=Seiji kn-aut-name=橋本成仁 kn-aut-sei=橋本 kn-aut-mei=成仁 aut-affil-num=2 ORCID= en-aut-name=NaraShigetoshi en-aut-sei=Nara en-aut-mei=Shigetoshi kn-aut-name=奈良重俊 kn-aut-sei=奈良 kn-aut-mei=重俊 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=Department of Electrical and Electronic Engineering affil-num=2 en-affil= kn-affil=Department of Electrical and Electronic Engineering affil-num=3 en-affil= kn-affil=Department of Electrical and Electronic Engineering END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue=1 article-no= start-page=55 end-page=64 dt-received= dt-revised= dt-accepted= dt-pub-year=1992 dt-pub=19921125 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Intrinsic Bistability of Coupled Quantum Wires: Localization due to Many-Body Effects en-subtitle= kn-subtitle= en-abstract= kn-abstract=The ground state of a system of electrons accumulated in a pair of coupled symmetric quantum wires is analyzed on the basis of density functional theory. It is shown that, in a domain of physical parameters, electrons are localized in either of wires. The main contribution to the total energy of this system comes from the Hartree energy, or the electrostatic energy, and the exchange-correlation energy between electrons. The ground state is determined by a competition between these contributions: We have symmetric electron distributions when the Hartree energy dominates and asymmetric (localized) states are realized in the opposite case. This kind of simple system with bistable electronic states may be applied to semiconductor memory devices. en-copyright= kn-copyright= en-aut-name=TotsujiHiroo en-aut-sei=Totsuji en-aut-mei=Hiroo kn-aut-name=東辻浩夫 kn-aut-sei=東辻 kn-aut-mei=浩夫 aut-affil-num=1 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=TachibanaHiroyuki kn-aut-sei=Tachibana kn-aut-mei=Hiroyuki aut-affil-num=2 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=HashimotoSeiji kn-aut-sei=Hashimoto kn-aut-mei=Seiji aut-affil-num=3 ORCID= en-aut-name=NaraShigetoshi en-aut-sei=Nara en-aut-mei=Shigetoshi kn-aut-name=奈良重俊 kn-aut-sei=奈良 kn-aut-mei=重俊 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=Department of Electrical and Electronic Engineering affil-num=2 en-affil= kn-affil=Department of Electrical and Electronic Engineering affil-num=3 en-affil= kn-affil=Department of Electrical and Electronic Engineering affil-num=4 en-affil= kn-affil=Department of Electrical and Electronic Engineering END
