Shunichi Ishijima,Naoto Shimizu,Tsuyoshi Masuda,Yoichi Seki,Seiji Tobita 한국공학교육학회 2012 공학교육연구 Vol.15 No.4

In this paper, the purpose and overview of the “Frontier Leadership Program for Engineering Students through Joint Participation of Higher Education and the Industrial Sector” (FLC: Frontier Leadership Course) in Gunma University is reported together with our achievements during the last three years. The purpose of this special educational program is to promote and educate selected students who are highly motivated to learn science & mathematics and to become an active leader in industrial sectors or research institutes. The activity can be divided into two categories: “Student-Proposed Stream” and “Advanced Research Stream”. These activities were found to be useful to cultivate student’s leadership and global communication ability. Furthermore, most of the FLC students cultivated the excellent academic performance and five students among them will be allowed to skip their fourth undergraduate year and enter directly into our graduate school.

Yeats and T. S. Eliot: Individual Talents, Traditions, and Dialogue with the Dead

Shunichi Takayanagi 한국T.S.엘리엇학회 2005 T.S. 엘리엇 연구 Vol.15 No.1

Based on T. S. Eliot’s cardinal literary essay “Tradition and the Individual Talent” (1919), this essay examines the two great poetic masters of the twentieth century, W. B. Yeats and T. S. Eliot. Touching on the poetic traditions of the two masters, this essay shows how much Eliot absorbed Yeats’s poetic tradition into his own poetry through the deep communion with his senior. The poetic tradition of W. B. Yeats is bound up with theosophy, magic, occultism, Irish mythology, Irish legendary heroes at the dawn of history, saints and poets wandering around the island before the coming of Anglo-Saxons. Yeats’s poetic world is fundamentally different from that of Eliot; Yeats’s existential sense of ‛prolonged genocidal humiliation’ is ‛the bitter culmination of seven centuries of British policy in Ireland’ while Eliot’s starting point is with ‘his sense of inner devastation’ against the background of ‘overwhelming desacralization of the Western world.’ Nonetheless, Eliot had learned much from the poetry of Yeats whose poetry is one of ‘refrain, of repetition in a finer tone, raised to the Sublime, to the limits of art.’ Such solemn refrains or incantations raised to the limits of language are also found in Eliot’s major poetic works; The Waste Land, “Ash-Wednesday”, and Four Quartets. On his part, obviously Yeats also learned something from his junior’s critical dictum, “No poet, no artist of any art, has his complete meaning alone. His significance, his appreciation is the appreciation of his relation to the dead poets and artists,” when he defined his theory of supreme art; “Supreme art is a traditional statement of certain heroic and religious truth, passed on from age to age, modified by individual genius, but never abandoned.”

Lessons to be learned towards a future waste management

( Shunichi Honda ) 한국폐기물자원순환학회(구 한국폐기물학회) 2021 한국폐기물자원순환학회 심포지움 Vol.2021 No.1

1. Introduction The human society existed before January 2020 will not come back to people. The Covid-19 Pandemic started as a small threat but drastically growing to a global crisis in a twinkling. Even after the second spring season came, people are still threated under the Covid-19 Pandemic in their daily lives without any expectation when the pandemic comes to the end. Its causes the completely unforeseen situation around every single item in the human society, including waste management. This pandemic could be part of the entire environmental crises that human triggered to cause. There is the triple planetary crisis: climate, nature and pollution crisis in the world. The Covid-19 Pandemic may be a last call to human to rethink, redesign and reconstruct their artificial society which heavily relies on the natural capita and causes negative impact on the environment. They silently say that the current system should be changed to sustainability with the circular economy. 2. Waste management under the Covid-19 Pandemic After the previous normal became unnormal now, waste management situation became more difficult. It seems that waste generation patterns have been changed: more organic waste, packaging waste, personnel protective equipment waste and medical waste, and less commercial waste generation. However, its comprehensive answer will tell us an exact result as a history of the Covid-19 Pandemic in our future. The Covid-19 Pandemic causes a new crisis on waste management at all the levels. At the initial emerging phase, there was no time to strategically consider what those waste should be treated and managed in an environmentally sound way. So far, the human society have been barely treating waste within their existing capacity and with available services and infrastructures. However, there is a need to strategically consider about tangible options to manage Covid-19 waste in environmentally sound way because people need to continue their lives with the Covid-19 Pandemic for time being. One of possible scenarios is integration of the Covid-19 waste management into the existing waste management: the human society would be able to more resilient against a possible future pandemic and its waste management. 3. Lessons to be learned When the high-income countries started their advanced waste management system embedded to circular economy, one of the important factors was globalization of environmentally sound management of waste and resource circularity connecting between downstream and upstream management. The Covid-19 Pandemic clearly reminds the human society of proximate principle of environmentally sound disposal of waste. As people face the triple planetary crisis, environmentally sound management of waste including immediate measures against Covid-19 waste and future pandemic waste contributes only to part of those crisis. During the period of the Sustainable Development Goals (SDGs) and the beyond SDGs towards the 2050 target on carbon neutrality by the major countries with the global efforts for the Paris Agreement, the current human society and its system should be transformed to be equitable, resilient and sustainable.

Deuterium kinetic isotope effects as redox mechanistic criterions

Shunichi Fukuzumi,Yong-Min Lee,남원우 대한화학회 2021 Bulletin of the Korean Chemical Society Vol.42 No.12

This account article focuses on deuterium kinetic isotope effects (KIEs) used as criterions to elucidate redox mechanisms including proton-, hydrogen- and hydride-transfer reactions. Hydrogen atom transfer (HAT) is composed of two elementary steps: electron transfer (ET) and proton transfer (PT), while hydride transfer is composed of three elementary steps: ET, PT, and ET. Large tunneling effects are often observed for proton-coupled electron-transfer (PCET) reactions of metal?oxygen complexes in which ET occurs to the metal center and PT occurs simultaneously to the ligand, exhibiting large KIEs. Whether HAT proceeds via sequential ET/PT, PT/ET, or concerted PCET (cPCET) depending on the redox properties of hydrogen donors and acceptors to exhibit different KIEs. Whether hydride transfer also proceeds via sequential ET/PT/ET, PT/ET/ET, or cPCET/ET depending on the redox properties of hydride donors and acceptors to exhibit different KIEs. Temperature dependence of KIEs for aldehyde deformylation reactions has enabled to distinguish two reaction pathways: one is a HAT and the other is a nucleophilic addition. The change of the mechanism from cPCET to sequential ET/PT is made possible by binding acids to the hydrogen and hydride acceptors when no KIE is observed. Inverse KIEs are also discussed for acid (or deuteron)-promoted ET reactions.

Background/Aims: We recently identified recessive mutations in the solute carrier organic anion transporter family member 2A1 gene (SLCO2A1 ) as causative variants of chronic nonspecific multiple ulcers of the small intestine (chronic enteropathy associated with SLCO2A1, CEAS). The aim of this study was to investigate the gastroduodenal expression of the SLCO2A1 protein in patients with CEAS and Crohn’s disease (CD). Methods: Immunohistochemical staining for SLCO2A1 was performed with a polyclonal antibody, HPA013742, on gastroduodenal tissues obtained by endoscopic biopsy from four patients with CEAS and 29 patients with CD. Results: The expression of SLCO2A1 was observed in one of four patients (25%) with CEAS and in all 29 patients (100%) with CD (p<0.001). The three patients with CEAS without SLCO2A1 expression had a homozygous splice-site mutation in SLCO2A1, c.1461+1G>C (exon 7) or c.940+1G>A (exon 10). The remaining one CEAS patient with positive expression of SLCO2A1 had compound heterozygous c.664G>A and c.1807C>T mutations. Conclusions: Immunohistochemical staining for SLCO2A1 in gastroduodenal tissues obtained by endoscopic biopsy is considered useful for the distinction of CEAS from CD.

A Framework of Managing Supply Chain Disruption Risks Using Network Reliability

Shunichi Ohmori,Kazuho Yoshimoto 대한산업공학회 2013 Industrial Engineeering & Management Systems Vol.12 No.2

This paper discusses how to manage supply chain disruption risks from natural disasters or other low-likelihood-highimpact risk drivers. After the catastrophic earthquake in Eastern Japan and the severe flood in Thailand, most companies have been attempting to re-establish the business continuity plan to prevent their supply chain from disruption. However, the challenges for managers and individual risks are often interrelated, and thus, actions that mitigate one risk can end up being no contribution as a whole. In this paper, we describe a framework for assessing how much impact individual mitigation strategies have on the entire supply chain protection against disruption, using network reliability. We propose three categories of risk-mitigation approaches: Stabilization, Absorption, and Duplication. We analyze the situation under which each of these strategies is the best suitable. With a clear understanding of relations between these mitigation strategies and the entire supply chain risks, managers can select effective risk-reduction approaches to their supply chain.
