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.

WTO·DDA 협상의 난항으로 FTA가 무역관련 규칙제정에 있어 주도적인 역할을 하고 있다. FTA 체결에 따른 이점의 하나는 GVC의 확대를 활성화시키는 잠재성에 있다. FTA는 GVC의 발전을 위해 대개의 필요한 정책상의 조치를 커버하기 때문에 이러한 목적을 달성하기에 적절한 수단이다. FTA는 글로벌 경제에 있어 GVC 운영자에게 무역장벽을 완화해 주는 역할을 한다. FTA는 즉시 관세를 경감하는 것은 아니지만 통관이나 무역원활화 조치를 가속화함으로써 비용을 경감할 수 있다. 대개의 선도적 FTA에서는 상대국에 GVC를 활성화시킬 수 있는 규제상의 조화와 같은 새로운 특성을 지속적으로 추가하고 있다. 최근 WTO와 OECD 등에서도 GVC에 대한 연구가 증가하고 있어, 무역에 대한 새로운 시각을 제공하고 있다. 본 연구에서는 FTA 확대에 따른 GVC의 활성화 방안을 도출하기 위해 최근 GVC에 대한 선행연구를 바탕으로 중소기업의 GVC 편입을 위한 글로벌 경쟁력 방안을 제시하고 있다.

본 연구는 GVC(글로벌가치사슬) 관점에서 한국의 해외직접투자(FDI)의 현황을 실증적 연구방법을 통해 분석하고 정책방향을 제시하였다. 전 세계 50개국의 자료를 활용한 회귀분석과 독일, 스위스, 싱가포르 등 주요국과의 국제비교 분석을 수행하였다. 분석결과 2000년대 이후 동시에 늘어나는 전 세계 FDI와 수출입을 동시에 설명하는 GVC 관점에서 볼 때, 한국의 국제화 수준은 지나치게 무역위주로만 형성되어 있는 것으로 나타났다. 특히, 한국의 1인당 GDP를 높이기 위해서는 분석에 포함된 주요국에 비해 20~30여년 뒤쳐져 있는 해외직접투자(OFDI) 수준을 높이는 것이 필요해 보인다. 즉, 무역의 이익과 투자의 이익을 동시에 추구하여 1인당 GDP 수준을 높여나가는 것이 중요한 것으로 분석되었다.

The study was conducted to investigate the effects of different harvesting time on pasting properties of starch in three colored rices. Seven major parameters of starch pasting properties, peak viscosity (PKV), hot pasting viscosity (HPV), cool pasting viscosity (CPV), setback (CPV minus PKV), breakdown (PKV minus HPV), peak time, and pasting time were determined by Rapid Visco Analyzer. The peak viscosity, hot viscosity, cool viscosity and peak time were influenced by different harvesting times. Pasting time was delayed slightly with prolonged harvesting time in all rice cultivars. Pasting temperature in each rice cultivar differed from each harvesting time, and pasting temperature of the two rice cultivars, Hongjinju and Joseongheugchal, showed the highest at the 40 days after heading and then it decreased at the final harvesting time. With the delay of the harvesting time, peak viscosity, hot viscosity, cool viscosity, setback value and pasting temperature did not exhibit a regular trend depending on their genetic characteristics. Branch chain length distribution of amylopectin was demonstrated a distinct difference among these colored rices. In changes of amylopectin branch chain-length distribution, the amylopectin structure of Hongjinju rice cultivar as affected by different harvesting time, the shortest chain length of amylopectin in rice starch harvested at 20 days after heading was characterized by the significant increase in A chains with $DP{\geq}12$ and remarked decrease in long chains $37{\leq}DP$ compared to that of 30, 40, and 50 days after heading. In particular, when harvesting time is delayed the distribution percentage of short chain (A chains with $DP{\geq}12$) was increased except for the rice which harvested 20 days after heading. The similar results were also observed in Sintoheugmi rice cultivar like that of Hongjinju rice cultivar. Otherwise, distribution percentage of the shortest chain length of amylopectin in rice starch harvested at 20 days after heading was characterized by the significant decrease in A chains with $DP{\geq}12$ and remarked increase in B chains $13{\leq}DP{\geq}24$ compared to that of 30, 40, and 50 days after heading.

This paper derives the gravity equation with intermediate goods trade. We extend a standard monopolistic competition model to incorporate intermediate goods trade, and show that the gravity equation with intermediates trade is identical to the one without it except in that gross output should be used as the output measure instead of value added. We also show that the output elasticity of trade is significantly underestimated when value added is used as the output measure. This implies that with the conventional gravity equation, the contribution of output growth can be substantially underestimated and the role of trade costs reduction can be exaggerated in explaining trade expansion, as we demonstrate for the case of Korea's trade growth between 1995 and 2007.

The early stage of the self assembly for octadecyltrichlorosilane (OTS)-based monolayers is investigated using atomic force microscopy (AFM). Height measurements using AFM prove that the island height of the monolayers gradually increases with increasing the island size, and is close to the limiting value (h = $\sim$25 $\AA$) after d = $\sim$600 nm in size. Since the theoretical length of a covalently bound OTS molecule is 26.2 Å, the limiting value of the island height means that the islands with d ${\geq}$ 600 nm consist of close-packed, fully extended chains. The heights for the islands with d < 600 nm are lower than the limiting value and decrease with decreasing the island sizes. This observation indicates that the OTS molecules in the small islands are less densely packed, and that the packing densities of the islands increase as the islands grow in size.

This paper investigates the effects of TPP on Korean domestic employment. Using data from 1995-2011 obtained from the world input-output database (WIOD) and firm-level data, this paper attempts to identify changes in global value chain (GVC) structures involving Korea and TPP member countries in the Asia-Pacific region. Three stage least squares estimation is employed, and empirical findings show that there exists a statistically positive and significant causal relationship between GVC and domestic manufacturing employment. The positive impacts of TPP on Korean domestic employment suggest that Korea actively encourage TPP negotiation. TPP will bring positive domestic employment effects and opportunities for structural transformation in the manufacturing and services industries in Korea.

This paper examines the impact of sanitary and phytosanitary standards (SPS) and technical barriers to trade (TBT) on Korean exports, taking global value chains (GVC) participation into consideration. Using product-level import data from 2000 to 2014, we find heterogeneous effects of importers' SPS and TBT on Korean exports depending on the degree and position of GVC participation. According to the results, trade restrictive effects of SPS and TBT are smaller for industries that are more deeply involved in GVC. However, trade restrictive effects are greater for industries located at a relatively upstream production stage in GVC.

Physicochemical properties of a series of PC monolayers with different alkyl chains (C24, C20, C16, and C8), at the air/water interface were investigated. The surface pressure is influenced mainly by the hydrophobicity of the PCs, which is confirmed by the curve shape and the on-set value of π-A isotherms at the air/water interface by increasing the number of alkyl chain. The on-set values of surface pressure were 125 Ų/molecule for DOPC(C8), 87 Ų/molecule for DPPC(C16), 75 Ų/molecule for DAPC(C20), and 55 Ų/molecule for DLPC(C24), respectively. The orientations of alkyl chains at the air/water interface are closely connected with the rigidity of the monolayers, and it was confirmed by the tendency of monolayer thickness in ellipsometry data. The temperature dependence of a series of PCs shows that the surface pressure decreases by increasing temperature, because the longer the alkyl chain length, the larger the hydrophobic interaction in surface pressure. The temperature effects and the conformational changes of unsaturated and saturated PCs were confirmed by the computer simulation study of the cis-trans transition with POPC and DPPC(C16). The cistrans conformational energy difference of POPC is 62.06 kcal/mol and that of DPPC(C16) is 6.75 kcal/mol. Due to the high conformational energy barrier of POPC, phase transition of POPC is limited in comparison with DPPC(C16).
