The purpose of this study is to empirically analyze the status and the trends in the international competitiveness of Korean export products against MINTs. For the study, the data were collected from the trade statistics for the period 2009-2012 produced by KITA and UN comtrade, and trade specialization index and market comparative advantage index were selected as index analysis methods. The findings from this study are as follows: First, Korea maintains a continuous increase of trade volume and trade balance in trade with MINTs, and exports finished goods, auto parts, etc. to MINTs, whlie mainly imports primary products such as energy fuels from MINTs. Second, Korea remains competitive in both product groups and individual products over MINTs. Third, even though Korean exports obtain a high competitiveness against MINTs, its competitiveness shows the differences by country. Several implications of this study are as follows: First, we need to take full advantage of energy resource-rich MINTs in securing stable energy fuels. Second, we should prepare response plans for the economic conditions which can have a negative impact on trade with MINTs, Third, we need to build strategies for maintaining the competitiveness of Korean exports over MINTs. Fourth, The differentiated export strategies should be established by country by considering differences in Korean exports' competitiveness which exist among the four countries of MINTs. Fifth, we need to prepare for such a situation which MINTs attempt to expand its influence by forming a collective economic cooperation.

This paper analyzes balance of goods for a panel data of 56 industry classification in the MTI from 1980 to 2009. This study also develops the equilibrium adjustment process, which is a trade-off between the adjustment costs towards equilibrium costs for balance of goods and the cost of being in disequilibrium. In this framework, the GMM estimation procedure is used to estimate this dynamic panel model consistently. It is found that equilibrium balances of goods in Korean adjust to the speed is very slow to 0.0389. because of this is necessary to adjust the equilibrium goods balance as the cost of goods balance deficit is larger than by the cost. In addition, the real income elasticity for goods balance of resin in Japan and Korea, the real income elasticity 4.38168 and -0.835225, respectively, the marks were consistent with economic theory. The exchange rate elasticity of goods balance in japan to 0.478435 were found in the inelastic.

Services, despite the difficulty of its exact definition, can be defined as deeds, efforts, or performances by economical bodies, attributing to four unique characteristics - intangibility, inseparability, heterogeneity, and perishability. This study aims to research the global competition and problems of the local professional services, especially educational services and health services, and to suggest some devices for increasing the exportation of both educational services and health services. Educational services and health services were reserved in the multilateral negotiation to open the WTO parties' markets because of its national public benefits. But it is indispensable to open our local market by the bilateral FTA negotiation. Legal restrictions, therefore, related to both education and health should be erased according to the basic rule of the market competition, and it is advisable to control the national public benefit of these services by enacting the different legal systems. For recovering from minus balance of payment in the educational services or health services, furthermore, it is necessary to drive rather some offensive exporting policies than the defensive policy against supply from the foreign countries. In conclusion, the korean Foreign Trade Act and other relative acts should be revised, and both educational services and health services should be contained within the definition of "the international trade" for the governmental benefits of supporting the services exportation.

Materials Industry has a very large ripple effect on national economic development. Nevertheless, Korea has been passing over importance of this Industry. So, this study examined competitiveness on ten chief exporting items to U.S.A market based on the understanding of vital role of materials industry in the national economy. Analyzing methods were Market Share, Trade Specialization Index(TSI), and Market Comparative Advantage(MCA) and the data were collected through parts and materials statistical data which produced by Korean Commerce and Industry Minister. From this study, following results were found. i) Highly ranked items of U.S.A market share were chemical fiber drapery weaving, synthetic fiber. These items commanded over 10% share of the same market and tire, steel wire occupied 9.05%, 8.65% respectively. ii) In searching trade balance aspects through TSI, tire and steel wire secured very powerful competitiveness among examined items in trading with U.S.A. while synthetic resins and other plastic material were very weak competitiveness in the same market. iii) Analysis results of market competitiveness by MCA, indicated that chemical fiber drapery weaving, synthetic fiber and tire ensured high-powered competitiveness in U.S.A Market. Therefore, these items would be positioned as main items in the market.

In this paper, we introduce a system and a set of algorithms for disseminating popular content to a large group of wireless clients spread over a wide area. This area is partitioned into multiple cells and there is a base station in each cell which is able to broadcast to the clients within its radio coverage. Dissemination of information in the proposed system is hybrid in nature: Each base station broadcasts a fraction of information in the form of random linear combinations of data blocks. Then the clients cooperate by exchanging packets to obtain their desired messages while they are moving arbitrarily over the area. In this paper, fundamental trade-offs between the average information delivery completion time at the clients and different parameters of the system such as bandwidth usage by the base stations, average energy consumption by the clients and the popularity of the spread information are studied. Moreover different heuristic algorithms are proposed to control and maintain a balance over these trade-offs. Also, the more complicated case of multiple sessions where each client is interested in an arbitrary subset of sessions is considered and two variants of the basic dissemination algorithm are proposed. The performance of all the proposed algorithms is evaluated via extensive numerical experiments.

The aim of this paper is to identify the key determinants in the Gulf Cooperation Council (GCC) countries for Foreign Direct Investment (FDI) inflows by using a balanced data panel for the period from 1995 to 2018. This study covers GCC countries in their entirety. The study uses ten explanatory variables, namely, trade ratio, gross domestic product, external balance, fuel exports, gross savings, international tourism, military expenditure, net foreign assets, services value added, and total natural resources. The authors have tried to find the best fit model from the differences methods considered such as OLS, GLS regression with the help of Hausman test, and country by country regressions as additional analysis. The study revealed a significantly positive association between inflation, trade ratio, gross domestic product, gross savings, and net foreign assets with FDI. On the contrary, international tourism was revealed to have a negative association with FDI. The sample of all GCC countries chosen for this study has not been considered widely by any earlier study. Moreover, this study covered many determinants of FDI that add to the previous literature. It is a significant contribution to the current research body and stresses the originality of this paper.

International remittances play a crucial role in the economic management of each country, especially in developing countries. Its functions are diverse, including procurement of foreign currency, serving as a cushion for the balance of payments and foreign exchange reserves by reducing the adverse external shocks, driving economic growth, easing the gap between the rich and the poor, and maintaining macroeconomic stability. However, previous studies on remittances have mainly focused on macro-and micro-economic aspects to analyze the determinants. Therefore, this study attempts to identify the determinants of remittances in 122 countries over the past 25 years from macroeconomic and educational aspects as well as institutional qualities. In addition, given the fact that almost all of the world's top 10 recipient countries in terms of GDP and total remittance size are developing countries, developed and developing countries are separated and analyzed for comparison, assuming that there may be a difference between the two groups. Results show that the coefficients of developed and developing countries are different in four areas: Control of Corruption (CC), Rule of Law (RL), Voice and Accountability (VA), and Regulatory Quality (RQ) among the six institutional variables of interest in this study. These results implicate that even the same institutions and policies should be applied and implemented differently depending on the circumstances of each country. In addition, as suggested by the World Bank, policymakers in all countries should double their policy efforts to lower the costs of remittance and improve access to the financial system for immigrants or dispatched workers to ensure a steady inflow of remittances.

The dispute analysed in this article concern eight measures taken by Argentina regarding finance, taxation, foreign exchange, and registration. The dispute centered on whether these measures were in violation of the Member's obligations under the General Agreement on Trade in Services (GATS), namely most-favored national treatment, national treatment and market access, and whether they are justified by Article XIV and Article 2(a) of the Annex on Financial Services. Important arguments raised in the dispute include whether the services and the service providers of cooperative and non-cooperative countries and/or Argentina subjected to the measures are like for the purposes of Article II and Article XVII of the GATS, whether the regulatory aspects of the measures are to be considered in determining the inconsistency with Article II and Article XVII of the GATS, and whether the measures are justified in that they were taken in accordance with the national laws and regulations aimed at implementing the Global Forum on Transparency and Exchange of Information for Tax Purposes and the Financial Action Task Force. The essence of this dispute lies in the balance of each Member's right to regulate commercial and/or financial activities and its obligations under the GATS. The Appellate Body tried to strike such a balance in its assessment of: (i) likeness of services and service suppliers, (ii) no less favorable treatment under Articles II and XVII, and (iii) the scope of measures under Article 2(a) of the Annex on Financial Services. This article aims to provide an analysis of the Appellate Body's findings, giving light to the relevant jurisprudence and scholars' writings.

As the classical response surface method (RSM), the polynomial RSM is so easy-to-apply that it is widely used in reliability analysis. However, the trade-off of accuracy and efficiency is still a challenge and the "curse of dimension" usually confines RSM to low dimension systems. In this paper, based on the univariate decomposition, the polynomial RSM is executed in a new mode, called as DPRSM. The general form of DPRSM is given and its implementation is designed referring to the classical RSM firstly. Then, in order to balance the accuracy and efficiency of DPRSM, its adaptive order revision around the most probable point (MPP) is proposed by introducing the univariate polynomial order analysis, noted as RDPRSM, which can analyze the exact nonlinearity of the limit state surface in the region around MPP. For testing the proposed techniques, several numerical examples are studied in detail, and the results indicate that DPRSM with low order can obtain similar results to the classical RSM, DPRSM with high order can obtain more precision with a large efficiency loss; RDPRSM can perform a good balance between accuracy and efficiency and preserve the good robustness property meanwhile, especially for those problems with high nonlinearity and complex problems; the proposed methods can also give a good performance in the high-dimensional cases.

This paper aims to analyze comparing the international competitiveness of Korea and China of ICT 10 goods in ASEAN Big 6 countries.(Malaysia, Indonesia, Vietnam, Singapore, Thailand, Philippines). In this study, we investigate major trends in Korea's ICT goods through various data analysis and evaluate. From 2009 to 2016, As analyzed by ESI, CTB, and EMS, This paper showed Korea has increased its export, EMS and Export Competitiveness to ASEAN. However, due to rapid imports, the trade balance deteriorated and ESI decreased. China showed signs of improvement in international competitiveness, although exports, ESI and EMS were declining. Compared to South Korea, China has seen less export bias to ASEAN. ASEAN is becoming an increasingly important trade partner in Korea's ICT exporting. This paper points out several policy implications drawn from its analyses and findings.
