Nowadays, social media has evolved into a powerful networked ecosystem in which governments and citizens publicly debate economic and political issues. This holds true for the pros and cons of Indonesia's ore nickel export restriction to Europe, which we aim to investigate further in this paper. Using Twitter as a dependable channel for conducting sentiment analysis, we have gathered 7070 tweets data for further processing using two sentiment analysis approaches, namely Support Vector Machine (SVM) and Long Short Term Memory (LSTM). Model construction stage has shown that Bidirectional LSTM performed better than LSTM and SVM kernels, with accuracy of 91%. The LSTM comes second and The SVM Radial Basis Function comes third in terms of best model, with 88% and 83% accuracies, respectively. In terms of sentiments, most Indonesians believe that the nickel ore provision will have a positive impact on the mining industry in Indonesia. However, a small number of Indonesian citizens contradict this policy due to fears of a trade dispute that could potentially harm Indonesia's bilateral relations with the EU. Hence, this study contributes to the advancement of measuring public opinions through big data tools by identifying Bidirectional LSTM as the optimal model for the dataset.

This study reviews the proposed liability and redress regime under the Cartagena Protocol on Biodiversity. Several core elements for the regime are discussed in comparison with those listed in the 1999 Basel Protocol on Liability and Compensation for Damage resulting from the Transboundary Movements of Hazardous Wastes and their Disposal. These are (1) scope of the rules and procedures; (2) channeling of liability; (3) legal standing; (4) definition of damage; (5) standard of care; (6) ancillary sources of compensation; (7) limitation of liability; (8) financial guarantees; and (9) mutual recognition and enforcement of judgments. Korea has given relatively little attention to the issue of liability and redress in the context of LMOs trade. As the Protocol is expected to enter into force soon, Korea needs to develop appropriate implementing domestic mechanisms for the Biosafety Protocol. Establishing an adequate domestic liability and compensation scheme will be one of the most important mechanisms not only to comply the Protocol but to ensure safety of LMOs in general. A further research is needed on the basis of a comparision of relevant legislations in different countries as well as analysis of current laws related to the accidents arising from LMOs trade, such as product liability laws, food safety laws, liability provisions in some environmental legislations.

FTA is the key post in international trade policy together with WTO. This paper studies the appraisal of bilateral Free Trade Association among Korea and Chile which has been started from April of last year. After FTA our actual results of export to Chile has been increased as forecasted but import from Chile hasn't increased as anxiety. Also Korea $\cdot$ Chile FTA gives us a political suggestion for propulsion of FTA with another countries hereafter.

This paper seek to clarify a narrow set of policy issues relating to the international trade aspects of electronic commerce. It focuses, in particular, on the WTO decision not impose customs duties on electronically delivered products. The decision on duty-free commerce is intended to contribute to the growth of electronic commerce by providing a guarantee of open trading conditions, but the significance of the decision may have been exaggerated. In particular, the prohibition of customs duties does not ensure continued open market access for electronically delivered products and may even prompt recourse to inferior instruments of protection. Accordingly, barrier-free electronic commerce would be more effectively secured by deepening and widening the limited cross-border trade commitments under the GATS and by clarifying and strengthening certain GATS disciplines.

Purpose - The purpose of this paper is to analyze the relationship between the real exchange rate and the output, which is based on the macroeconomic equilibrium theory in China. Its aim will be to verify whether the change in the real exchange rate has a significant effect on the output or not. Research design, data, and methodology - This study endeavors tries to investigate the correlation among economic variables under the macroeconomic market (the commodity market and the money market) equilibrium. So, time-series data from 1990 to 2016 is applied to establish a vector auto-regression (VAR) model so as to perform an empirical analysis. Results - The empirical results reveal that an increase in the real exchange rate will result in an increase in the output in the short run. However, the empirical results also indicate that this kind of mechanism cannot work in the long run. Conclusions - The effect of a decrease of real exchange rate on output is significant in the short run. Also, this paper suggests that the total supply and the total demand can promote economic growth. The fiscal and money policy play a significant role in economic growth in China as well.

This study aims to grasp the hierarchy in the influence areas of port by the intensity of freight shipments and to seek the activating methods for the increase of export and import volumes of Pyeongtaek and Dangjin port. Pyeongtaek and Dangjin port whose major import and export freights are natural gas and automobile, were constructed for the increasing trade with People's Republic of China. This port is expanding the influence in the hinterland and foreland of the port, but core influence area of Pyeongtaek and Dangjin port is rich in trade volume within the radius of 70km. To become international as well as national ports, Pyeongtaek and Dangjin is required to execute the active policy to receive many-sideness of sea route and the recognition of freight holders, forwarders and ship companies in many regions.

In the process of containerization, the problem of regional maldistribution of container management plan arises seriously due to several factors like a number of unbalances of containers between loading and discharging ports. This study focus on the minimizing cost. This study is composed of two models which in effective management decision making show decision of the number of containers and transfer of empty containers. One is decision of the number of containers which carriers should possess by appropriate forecasting and the other is effective management decision making which includes the transfer of empty containers on calling ports. This study has suggested as follows, First, the Time Series analysis method, especially the "Exponential Smooting with Trend Adjustment" was used to forecast the trade volumes for the designated traffic route. Second, the Time Series analysis method in deciding the optimal number of owned container at the unbalances trade situation between East Bound and West Bound service, most important variables were found such as total traffic volume, the calling interval at a port, the number of days of voyage and the length of stay on shore of container for the optimal number of owned container. Third, effective management decision making model, which makes it possible to analyze the impacts of change in important matters such as lease and positioning policy, and actually influence decision making.on making.

WTO Government Procurement Agreement (GPA) was designed to liberalize and expand trade in government procurement. Revised GPA was implemented in 1996 and the latest revision was completed (but not yet implemented) in 2012, but as a plurilateral agreement. Since the end of the UR, there has been attempts by various WTO members to liberalize trade in the government procurement market - through an expansion of Parties who are signatories to GPA, and through a negotiated agreement on transparency in government procurement. The attempt to expand the Parties who are signatories to the GPA - attempt to increase the width of the coverage of the agreement - has been somewhat successful, but I argue that the goal should be to further liberate the government procurement markets of the current Party members - to reduce thresholds and other barriers which limit market access even to other GPA members, in other words, to increase the depth of coverage. Taking cue from Korea's FTA, I propose a two-level liberalization of the government procurement market under the GPA: A "light" level which would be the same as the current level of liberalization; and a "deep" level with lower thresholds and less exemptions. I argue that, as seen in Korea, with FTAs, many GPA Parties already have multiple levels of liberalization (i.e, spaghetti-bowl effect of FTAs), but by limiting the levels of liberalization to two, we can seek the best of deep liberalization but reduce the spaghetti-bowl effect.

The renewable energy systems have been in the spotlight as an alternative for environmental issues. Therefore, the governmental policies are being implemented to spread of promote power generation system using renewable energy in various countries around the world. In addition, Korea has also developed a policy called the power trading contract which can profit from electricity produced from renewable power generation system through Korea Electric Power Corporation (KEPCO) and Korea Power Exchange (KPX). As a result, the power trading contracts can trade power after self-consuming in-house by using small-scale renewable power system for residential customers as well as electricity retailers. The power trading contracts applicable as a small-scale power system have a 'Net metering (NM)' and a 'Power Purchase Agreement (PPA)', and these two types of power trading contracts trade surplus power, but payment method of each power trading is different. The microgrid proposed in this paper is based on grid connected microgrid using Photovoltaic (PV) system and Energy Storage System (ESS), that supplied power to residential demand, we evaluate the operation cost of microgrid by power demand in each power trading contracts and propose the appropriate power trading contracts according to electricity demand.

Purpose - First, this study contextually examines the governance codes of South Africa and South Korea. Second, it analyzes board features of South African (JSE) Mainboard and South Korean (KRX) KOSPI-listed companies. Design/methodology - This review is qualitative and uses data from the annual reports of the selected markets' companies, respective exchanges' official web sites and corporate governance-related web sites in order to examine the corporate governance practices in the two markets. In addition, Nvivo is employed in analyzing the content of the corporate governance codes of the selected countries. Findings - Our analysis indicates that the corporate governance codes of the two countries are evolving to keep up with the international trend of principles-based approach. The composition of the board of directors (BODs) of non-financial companies of both South Africa and South Korea shows no significant variation between the companies with regards to the executive (inside) and nonexecutive (outside) directors. On the contrary, there is a significant variation between South African and South Korean listed companies with respect to diversity. Originality/value - While previous studies are centered on the impact of governance codes on performance, this study intends to contextually evaluate the codes and features of South Africa and South Korea listed companies. This is essential and timely for regulators and policy makers given the importance of corporate governance features such as board independence and diversity in recent times.
