ABSTRACT

Due to the spread of COVID-19, people are starting to be more aware and careful when touching any devices in public. To reduce physical contact with public devices, we have developed a method that enables users to interact with many kinds of public devices using the browser on their smartphones. This method is called Chameleon because it resembles the ability of the animal chameleon to change its color according to its surrounding environment. We have developed the prototype system to confirm the mechanism of Chameleon. Then, we have applied the Chameleon method to two practical systems in the campus of Nagasaki University that is expected to be used by multiple users. These two systems are a Certificate Issuance System for students and a Digital Signage System, that provides directions to campus visitors. Through these experiences, we confirmed the availability of the Chameleon method as the new type of the browser included not only Web server browsing functions but also public device operation functions. © 2022 IEEE.

ABSTRACT

This paper provides empirical evidence that suppor ts the continuing impor tance of machinery international production networks (IPNs) in East Asia. We first confirm their robustness and resilience, even during the coronavirus disease (COVID-19) pandemic, as well as the significance of East Asian countries as suppliers of machinery final products and par ts and components for the world. Then, we demonstrate how deeply East Asian countries are committed to machinery IPNs by applying a gravity equation to pre-pandemic bilateral machinery trade and comparing actual values with fitted values of the estimated equation. The gravity estimation exercise indicates that machinery trade is basically regional— within Factory Asia, Factory Nor th America, and Factory Europe—but Factory Asia also has strong inter-regional linkages. It also verifies that ASEAN has played an impor tant role in Factory Asia, going far beyond the gravity prediction, for the development of machinery IPNs. © 2022 by the Asian Economic Panel and the Massachusetts Institute of Technology.

ABSTRACT

This chapter provides an overview of the content in this volume on East Asian economic integration. It outlines debates about the nature and value of trade and economic integration, and examines whether East Asia will follow a similar evolution in the debate, as well as how East Asia will be affected by the growing anti-trade and anti-globalisation policy debates. The overview also includes policy discussions on the development of the coronavirus disease (COVID-19) pandemic and its implications for East Asia. Following this discussion, it reviews the chapters of the volume in terms of four areas of focus relevant for the future development of East Asia: (i) new regional and multilateral trading arrangements: analysis and evaluation;(ii) production networks, investment policies, and global value chains;(iii) structural transformation, skills, and domestic capacity;and (iv) infrastructure, digital technologies, regional security, and environment. © The Editors and Contributors Severally 2021.

ABSTRACT

Due to the spread of new coronavirus infections, it is desirable to allow people to use public devices such as PIN type smart locks or vending machines without touching them directly. Therefore, we developed a method that enables contactless operation of various public devices using personal smartphones while reducing the impact on existing public devices. This method imitates chameleons of the animal. Therefore, we call it chameleon. We developed the chameleon based on Web application and applied it to PIN type smart locks. Then, we confirmed the effectiveness of the chameleon as the method of contactless operation. © 2021 IEEE.

ABSTRACT

This paper investigates the impacts of COVID-19 on international production networks in machinery sectors by shedding light on negative supply shocks, negative demand shocks, and positive demand shocks. Specifically, we examined changes in trade in the trade-fall periods amid COVID-19 in 2020 using Japan's machinery trade at the most disaggregated level and decomposed them into two intensive margins (i.e., the quantity effect and the price effect) and two extensive margins (i.e., the entry effect and the exit effect). Our empirical results show that trade relationships for parts and components were robust even amid COVID-19 and that international production networks in machinery sectors were almost intact. They also demonstrate that COVID-19 brought positive demand shocks for specific products with special demand due to its nature in addition to negative supply shocks and negative demand shocks, which partially explains heterogeneous effects not only among sectors but also among products in the same sector. As of October 2020, Japan's machinery trade seems to have mostly recovered.
