The Current State of Green Logistics Development in Developed Countries and a Consideration of Its Feasibility in China
Get PDFSince the late 1990s, green logistics, which is logistics that takes into account the reduction of environmental impact, has become a growing concern in Chinese society and is necessary for the development of China’s logistics industry. However, green logistics in China got off to a slow start and there is still a significant gap with developed countries. As the Chinese economy has already become an important component of the global economy, green logistics must be developed to a great extent.This study mainly focuses on the development status of green logistics in developed countries and discusses feasible proposals for the development of green logistics in China through examples from developed countries.1990年代後半から、環境負荷軽減を考慮した物流であるグリーン物流が中国社会でも関心が高まり、中国の物流業の発展に必要とされている。しかし、中国のグリーン物流のスタートは遅く、先進国とはまだ大きな差がある。中国経済は、すでに世界経済の重要な構成部分となっているため、グリーン物流を大いに発展させなければならない。本研究では、先進国のグリーン物流の発展状況を主な研究対象とし、先進国の事例を通じて、中国におけるグリーン物流の発展に向けた実現可能な提案を行う。departmental bulletin pape
Understanding Geodesics and Curvature Tensor using SageMath
Get PDFThe curvature tensor of 4-dimensional spacetime, which appears in general relativity, is difficult to understand because it is a complex tensor with four subscripts. Since it is impossible to visualize geodesics and curvatures in 4-dimensional spacetime, we visualized geodesics and calculate curvature tensors of 2-dimensional surfaces, which corresponds to a 2-dimensional Riemann plane in 3-dimensional Euclidean space in order to understand the meanings of geodesics and curvature tensors. For the visualization and the calculation, we used SageMath, which is a free computer algebra system software. We found that the visualization of these geodesics and the calculation of curvatures on a 2-dimensional surface in 3-dimensional Euclidean space is useful for understanding their meanings. The usefulness of SageMath is also clarified.departmental bulletin pape
Production Districts of A Native Variety of Black Soybean “Tambaguro” in Sasayama, Hyogo
Get PDFWe aim to clarify the reasoning behind farmers and communities farming tambaguro which is a native soybean variety, in Sasayama, Hyogo Prefecture. Data were collated from interviews and postal surveys. Tambaguro is a substitute crop to rice production. Producing tambaguro is potentially profitable although its cultivation is labor intensive as the production process has not been mechanized. However, many farmers had no choice but to grow tambaguro due to the rice production adjustment. Conversely, many farmers planted tambaguro for their personal consumption or as a gift because of its superior flavor. Therefore, native variety conservation must be managed with a broad perspective that incorporates various social and cultural conditions.本稿は，兵庫県篠山市における大豆の在来品種・丹波黒の生産が，農家および農業集落レベルでどのように行われているのかについて，現地調査および郵送調査で明らかにすることを試みた。丹波黒は水田転作作物に位置づけられ，一定の収益が見込めるものの，機械化されていない作業が多く労力がかかる。アンケートでは，収益性の高さのほか，減反対応を理由に栽培を続ける農家が目立ったが，食味の良さから自給用や贈答用に作付しているという理由も見られた。在来品種の生産存続の条件は，経済性のみならず，文化的・社会的に埋め込まれた農産物として，より広範な観点から検討する必要があることが確認できた。departmental bulletin pape
Survey on Tourism Consumption by Inbound Chinese: From the Standpoint of the Intentions and Capability of Value Co-creation Marketing
Get PDFThe government,in formulating the tourism policies for the post-coronavirus era, is aiming at increased spending on “entertainment and recreational services”. These policies, however, are from the viewpoint of the government and Japanese businesses, so there exists a possibility that they are significantly deviated from the needs of Chinese tourists. This is because a key point in tourism is to focus on the consumption process from the consumers’ standpoint.
With this in mind, we consider marketing activities geared to inbound tourists from China using a value co-creation marketing approach. This paper gathers data focusing on the processes that take place before, during, and after consumption from the standpoint of value co-creation marketing. The purpose of this paper is to categorize such data from the viewpoint of customers’ intentions.日本政府はコロナ後を見据えた観光政策を立案して「娯楽等サービス費」の増加を目指している。しかし、これらの政策は行政側、日本の事業者側からの考察であり、中国人観光客のニーズと大きな乖離が生じている可能性がある。なぜならば、観光で重要な視点は消費者の立場で消費プロセスに注目することだからである。
このような問題意識から中国人インバウンドに対するマーケティング活動を検討するために価値共創マーケティングのアプローチで考察する。本論文は価値共創マーケティングの視点から消費前、消費中、消費後のプロセスに焦点を当てて情報収集する。そして、顧客を意志と能力の視点で考察することが目的である。departmental bulletin pape
A Content Analysis of Odor-evoked Involuntary Autobiographical Memory and Subjective Well-being in Young and Older People: Using Text Mining with Correspondence Analysis
Get PDFThis study examined gender and generational differences in the content of odor-evoked autobiographical memory and subjective well-being. Two hundred young and two hundred older people were asked to record their memories of past events, that is, autobiographical memories, when they were recalled by odor cues in their daily lives using a diary method. The subjective well-being scale was also completed. As a result of the analysis with gender and generation as independent variables, the interaction tended to be significant for subjective well-being, with older people having higher subjective well-being than the young in males, but no such difference was observed in females. In addition, women had higher subjective well-being than men in younger people, but no difference was found among older people. A correspondence analysis of the memory contents by text mining suggested that recalled memory content may differ by gender and generation. In the future, it is necessary to aim for applied development, such as reminiscence therapy.departmental bulletin pape
Game Engagement and Favorite Game Titles in College Students and General Adults: A Comparative Study of Using Text Mining with Correspondence Analysis
Get PDFIn recent years, there has been much psychological research on video gaming. This study compares game engagement and favorite game titles among college students and general adults. We conducted a survey sampling two hundred and eighty-nine college students and five hundred and fifty-nine general adults who completed the Game Engagement Questionnaire （GEQ）. Results show college students rated significantly higher compared to general adults on immersion and spatial presence factors of the GEQ. No significant differences are found between the groups in absorption and flow factor, which are subfactors in the GEQ. In addition, no difference in game play time between the groups is evident. These results suggest the time of day, rather than number of hours of game playing, may influence the gaming disorder. Furthermore, results of the text mining with correspondence analysis suggests there may be differences in the content of favorite game titles between college students and general adults.departmental bulletin pape
