Asia-Pacific Trade and Investment Review

This chapter shows that the Republic of Korea has experienced significant change in both trade and foreign direct Investment (FDI) flows since the 1997 Asian financial crisis. The analysis indicates that a rapid increase in exports at the onset of the crisis helped to improve foreign reserves of the Republic of Korea and also helped the economy to recover from severe recession. Despite the crisis, the importance of the Chinese market has steadily increased to the point where it is the most important export market for the Republic of Korea, largely at the expense of the Association of Southeast Asian Nations (ASEAN) market. The crisis also had a significant impact on FDI inflows, both in terms of source country and host industry. FDI increased sharply following the crisis, and this rapid increase was largely due to higher United States and European Union investment in the service sector, which is consistent with the wealth effect hypothesis on FDI flows. Meanwhile, Japanese FDI decreased, resulting in a decline in FDI in the manufacturing sector. However, the expected spillover effects of FDI are debatable, due to largely to a shape increase in mergers and acquisitions, and FDI dried up in technology-intensive manufacturing industry. In contrast, the Republic of Korea's outward direct investment seemed to be little influenced by the financial crisis, although a further study of the implications of the crisis for the Republic of Korea's outward direct investment in developing countries, including the traditionally popular Asian region, also needs to be investigated further.Korea, FDI, ODI, export, Asian financial crisis, 1997

Trade and foreign direct investment patterns in the Republic of Korea in the aftermath of the 1997 Asian financial crisis

This paper analyses the impacts of the 1997 financial crisis on global multinational enterprises' (MNEs) investment behaviours towards Korea applying the system estimation methodology. Our results indicate that MNEs from the European Union (EU) area seemed to be more motivated by the sharp drop in value of the host economy's currency and imports, whereas the US and Japanese MNEs were relatively sluggish to respond to the crisis in number of projects.Griffith Business School, Department of International Business and Asian StudiesFull Tex

Beacon-based Distributed Structure Formation in Multi-agent Systems

Autonomous shape and structure formation is an important problem in the domain of large-scale multi-agent systems. In this paper, we propose a 3D structure representation method and a distributed structure formation strategy where settled agents guide free moving agents to a prescribed location to settle in the structure. Agents at the structure formation frontier looking for neighbors to settle act as beacons, generating a surface gradient throughout the formed structure propagated by settled agents. Free-moving agents follow the surface gradient along the formed structure surface to the formation frontier, where they eventually reach the closest beacon and settle to continue the structure formation following a local bidding process. Agent behavior is governed by a finite state machine implementation, along with potential field-based motion control laws. We also discuss appropriate rules for recovering from stagnation points. Simulation experiments are presented to show planar and 3D structure formations with continuous and discontinuous boundary/surfaces, which validate the proposed strategy, followed by a scalability analysis.Comment: 8 pages, 6 figures, accepted for publication in IROS 2023.

Board meeting attendance by outside directors

Outside directors’ regular board meeting attendance is important in improving the effectiveness of a governance system. Such attendance is evidence of their commitment to the firm as key other players in monitoring and decision making. Using a unique dataset for Korean firms, and three-level random coefficients models, we find that, foreign outside directors, an independent appointment process, professional knowledge of business operations and accumulated firm-specific knowledge are important factors that affect outside directors’ attendance of board meetings. The results also confirm that both outside directors’ personal characteristics and the social context are crucial in understanding their board meeting attendance. Further analysis shows that a positive corporate environment that supports the outside director system encourages outside directors’ attendance at board meetings.Griffith Business School, Department of International Business and Asian StudiesFull Tex

TLR3 signaling is either protective or pathogenic for the development of Theiler's virus-induced demyelinating disease depending on the time of viral infection

Background: We have previously shown that toll-like receptor 3 (TLR3)-mediated signaling plays an important role in the induction of innate cytokine responses to Theiler\u27s murine encephalomyelitis virus (TMEV) infection. In addition, cytokine levels produced after TMEV infection are significantly higher in the glial cells of susceptible SJL mice compared to those of resistant C57BL/6 mice. However, it is not known whether TLR3-mediated signaling plays a protective or pathogenic role in the development of demyelinating disease. Methods: SJL/J and B6; 129S-Tlr3(tm1Flv)/J (TLR3KO-B6) mice, and TLR3KO-SJL mice that TLR3KO-B6 mice were backcrossed to SJL/J mice for 6 generations were infected with Theiler\u27s murine encephalomyelitis virus (2 x 10(5) PFU) with or without treatment with 50 mu g of poly IC. Cytokine production and immune responses in the CNS and periphery of infected mice were analyzed. Results: We investigated the role of TLR3-mediated signaling in the protection and pathogenesis of TMEV-induced demyelinating disease. TLR3KO-B6 mice did not develop demyelinating disease although they displayed elevated viral loads in the CNS. However, TLR3KO-SJL mice displayed increased viral loads and cellular infiltration in the CNS, accompanied by exacerbated development of demyelinating disease, compared to the normal littermate mice. Late, but not early, anti-viral CD4(+) and CD8(+) T cell responses in the CNS were compromised in TLR3KO-SJL mice. However, activation of TLR3 with poly IC prior to viral infection also exacerbated disease development, whereas such activation after viral infection restrained disease development. Activation of TLR3 signaling prior to viral infection hindered the induction of protective IFN-gamma-producing CD4(+) and CD8(+) T cell populations. In contrast, activation of these signals after viral infection improved the induction of IFN-gamma-producing CD4(+) and CD8(+) T cells. In addition, poly IC-pretreated mice displayed elevated PDL-1 and regulatory FoxP3(+) CD4+ T cells in the CNS, while poly IC-post-treated mice expressed reduced levels of PDL-1 and FoxP3(+) CD4(+) T cells. Conclusions: These results suggest that TLR3-mediated signaling during viral infection protects against demyelinating disease by reducing the viral load and modulating immune responses. In contrast, premature activation of TLR3 signal transduction prior to viral infection leads to pathogenesis via over-activation of the pathogenic immune response

Variability of extracorporeal cardiopulmonary resuscitation utilization for refractory adult out-of-hospital cardiac arrest: an international survey study.

Objective: A growing interest in extracorporeal cardiopulmonary resuscitation (ECPR) as a rescue strategy for refractory adult out-of-hospital cardiac arrest (OHCA) currently exists. This study aims to determine current standards of care and practice variation for ECPR patients in the USA and Korea. Methods: In December 2015, we surveyed centers from the Korean Hypothermia Network (KORHN) Investigators and the US National Post-Arrest Research Consortium (NPARC) on current targeted temperature management and ECPR practices. This project analyzes the subsection of questions addressing ECPR practices. We summarized survey. Results: Overall, 9 KORHN and 4 NPARC centers reported having ECPR programs and had complete survey data available. Two KORHN centers utilized extracorporeal membrane oxygenation only for postarrest circulatory support in patients with refractory shock and were excluded from further analysis. Centers with available ECPR generally saw a high volume of OHCA patients (10/11 centers care for \u3e75 OHCA a year). Location of, and providers trained for cannulation varied across centers. All centers in both countries (KORHN 7/7, NPARC 4/4) treated comatose ECPR patients with targeted temperature management. All NPARC centers and four of seven KORHN centers reported having a standardized hospital protocol for ECPR. Upper age cutoff for eligibility ranged from 60 to 75 years. No absolute contraindications were unanimous among centers. Conclusion: A wide variability in practice patterns exist between centers performing ECPR for refractory OHCA in the US and Korea. Standardized protocols and shared research databases might inform best practices, improve outcomes, and provide a foundation for prospective studies

Abnormal phase flip in the coherent phonon oscillations of Ca2RuO4

We employ an optical pump-probe technique to study coherent phonon oscillations in Ca2RuO4. We find that oscillation amplitude of an Ag symmetric phonon mode is strongly suppressed at 260 K, a putative transition point of orbital ordering. The oscillation also shows a gradual but huge change in its phase, such that the oscillation even flips over with a 180 change across the temperature. Density functional theory calculations indicate that the Ag phonon has an eigenmode of octahedral distortion with conventional tilting along the a axis and antipolar distortion of apical oxygen. Careful inspection of the lattice captures an unusually large antipolar distortion in low-temperature structures, which may play a crucial role for the phase transition at 260 K. ©2018 American Physical Societ
