  • This paper provides empirical evidence on the reorganization of GVCs in East Asia, highlighting that structural trends explain a decrease in the fragmentation of production after 2011 but that it is not the result of rising trade costs along the value chain. Using harmonized inter-country input-output tables, the paper first analyzes the global import intensity of production to document changes in the structure of GVCs. It then calculates theory-consistent bilateral trade costs for intermediate and final products using an approach derived from the gravity literature and introduces a new index of cumulative trade costs along the value chain. These data are used to discuss whether the decrease in global imports is the consequence of shifts in demand, efficiency-enhancing strategies of firms or rising trade costs. Between 2011 and 2016, cumulative trade costs have decreased in East Asian GVCs. However, as COVID-19 is likely to intensify trade and investment uncertainties, trade costs could increase in the future. Policies aimed at reducing uncertainties and preserving the gains from trade and investment liberalization will be key in this new environment.

  • Each country's economic progress creates opportunities for its citizens to raise their income. Meanwhile, the country has secured the people's social security policies, particularly the protection of income equality, to promote harmonious and sustained economic development. Vietnam has been located in a dynamic economic development area in Southeast Asia since the 1986 economic reforms, with an annual growth rate of around 7%. Meanwhile, having achieved a middle-income status of roughly 3500 USD per person per year, Vietnam is attempting to maintain income equality and access to welfare systems for its inhabitants. As a result, the primary goal of this study is to use an autoregressive distributed lagged model to investigate the effects of income inequality and other economic factors such as foreign direct investment and trade openness on Vietnam's economic growth from 1992 to 2019. The research focuses attention on literature on income inequality, economic development indicators, and economic development in unique ways in this study. Income inequality slows the rate of change in economic development in the same year, according to our findings. Finally, the study will make policy suggestions to the Vietnamese government.

  • With a view to providing a unitary interpretation of a lexical item, even, this paper proposes that even be understood as a quantifier. To countenance this idea, the quantifier theories will be evaluated against the implicature accounts on the basis of conceptual and empirical evidence. With the help of Bach (1999), the quantifier theories of even are regarded as most viable and plausible. On the other hand, from among different quantifier approaches even will be viewed as a quasi-universal quantifier, which means that even is similar to the universal quantifier but still it is different from it. That is, even introduces a comparison set that is context-dependent and only the salient members of this comparison set will be taken into account when an even-sentence is to be uttered. This observation is based on the formal representation for a universal quantifier in general on the one hand and the truth-conditional contribution of even to the sentence containing it.

  • The Korea urbanization has been accelerated without regard to regional traits and the environment. Most of rural areas have been overurbanized with proper and long term plan. Especially the case of Yongin-community which is located 50km south of Seoul reveals a typical wrong urbanization policy. Evidence of such wrong policy is proved by this study for last three decades(1970-2000) in political economic approach with special reference to the Manuel Castells' theory. The study concludes that urbanization with no proper development plan is mostly vulnerable and wasteful. And the environment is once spoiled, it is almost impossible to recover, so it is necessary for us long term and proper plan before development.

The Preferred Conformation of the Muscarinic Agent L(+) Acetyl-${\beta}$-Methylcholine

  • It has been postulated that acetylcholine exhibits both nicotine and muscarinic activity because of its ability to present two patterns of essential atoms to the receptors. These two patterns arise from the ability of the molecule to exist in more than one preferred conformation. The molecule S(+)-acetyl-${\beta}$-methylacetylcholine exhibits only muscarinic activity. Calculations using molecular orbital theory predict that this molecule prefers only the muscarinic conformation. This is offered as an explanation for the exclusive role of the molecule and as evidence supporting the twoconformation, two-activities hypothesis.

  • Recent experimental evidence that fluorinated graphene creates local magnetic moments around F adatoms has not been supported by semilocal density-functional theory (DFT) calculations where the adsorption of an F adatom induces no magnetic moment in graphene. Here, we show that such an incorrect prediction of the nonmagnetic ground state is due to the self-interaction error inherent in semilocal exchange-correlation functionals. The present hybrid DFT calculation for an F adatom on graphene predicts not only a spin-polarized ground state with a spin moment of ${\sim}1{\mu}_B$, but also a long-range spin polarization caused by the bipartite nature of the graphene lattice as well as the induced spin polarization of the graphene states. The results provide support for the experimental observations of local magnetic moments in fluorinated graphene.

The Effects of Firms' Foreign Market Focus on the Bias of Analysts' Earnings Forecasts: Focusing on CEO Characteristics (기업의 해외시장 집중화가 애널리스트 성과예측정보에 미치는 영향: 최고경영자 특성의 조절효과)

  • This paper investigates the effects of firms' foreign market focus on the optimistic bias of analysts' earnings forecasts. Based on a sample of 852 U.S. manufacturing firms between 1994 and 2015, our empirical results suggest that higher growth of foreign market focus is associated with greater levels of analysts' forecast optimism. Drawing on the CEO career horizon and the upper echelon theory literature, we find evidence that CEOs' career horizon and functional background as a CFO moderates the relationship between the growth rate of foreign market focus and analysts' forecast optimism. This shows that while financial analysts perceive internationalization strategies as signaling growth potential, such perception can vary depending on CEOs' individual characteristics.

  • If a firm announces an investment in IT security, how the market value of its competitors reacts to the announcement? We try to shed light on this question through an event study design. To test the relationship, we collected 143 announcements on cybersecurity investment and measured the subsequent impact on 533 competitors' abnormal returns, spanning from 2000 to 2019. Our estimation results present that, on average, the announcements have no observable impact on the market value of announcing firms and competitors as well, which is consistent with findings of a prior study. Interestingly, however, the impact becomes evident when we classify our samples by industries (Finance vs. non-Finance or ICT vs. non-ICT) and firm size (Big vs. Small). We interpret our empirical findings through the lenses of contagion effect and competition effect between announcing firms and their competitors. Key finding of our study is that, for financial service firms, the effect resulting from the announcement on cybersecurity investment transfers to competitors in the same direction (i.e., contagion effect).

  • Advances in individual genome sequencing technology and next generation sequencing technology have allowed for widespread research of human genome, which would give us opportunities not only to change our focus from the experience-based Korean medicine including typology and Sasang constitution to the evidence-based Korean medicine but to provide effective tailored medical care and Tang theory.

  • Semiconductor diode detectors coated with neutron reactive material are presently under investigation for various uses, such as remote sensing of thermal neutrons, fast neutron counting, and thermal neutron radiography. Theory indicates that single-coated devices can yield thermal neutron efficiencies from 4% to 11 %, which is supported by experimental evidence. Radiation endurance measurements indicate that the devices function well up to a limiting thermal neutron fluence of $10^{13}/cm^2$, beyond which noticeable degradation occurs. Thermal neutron contrast images of step wedges and simple phantoms, taken with dual in-line pixel devices, show promise for thermal neutron imaging detectors.
