The large increase in RTAs since the late 1980's has challenged the foundations of the multilateral trading system, and thereby has become an axis in the GATT/WTOsystem.While RTAs can be seen to be contradictory to the overall aim of the WTO, they were allowed for in Article XXIV of GATT conditional to certain provision. The failure of compliance and subsequently enforcement of these provisions could be seen as a serious flaw of Article XXIV since the inception of GATT system. Many elements of GATT Article XXIV are not clear and thus lead to divergent interpretations of its disciplines. This considerable divergence in opinions arise from both ambiguities throughout the provisions under GATT Article XXIV. In this regard, both economic and legal work is required to keep up with constantly changing nature of the world trading system. Further, global efforts are required to resolve another teething issue of WTO's problematic institutional framework on GATT/WTO's oversight and surveillance of RTAs. and thereby strengthen the multilateral trading system. Needless to say, theGATT/WTOframework has been essential in paving the way for RTAs while ensuring a more multilateral and liberal trading system. Consequently, global efforts should be made to restructure the WTO for the renewed multilateral trade liberalization in the GATT/WTO.

With the revitalization of non-face-to-face transactions, the difference between the size of branches and transaction costs among securities firms has decreased, and the importance of the stock trading system has increased. In particular, the mobile trading system has become more important due to the increase in the proportion of transactions in the mobile trading system, which is widely used by individual investors, and the increase in the number of individual investors after COVID-19. However, user-centered usability studies are insufficient as usability studies on mobile trading systems are conducted through literature surveys or survey methods. Therefore, in this study, a repertory grid technique that finds user's empirical perception was used to find out user-centered usability attributes. The usability attributes of the mobile trading system from the user's point of view were elicited, and the difference in the usability attributes in terms of frequency and importance between the user group and the developer group was identified.

This paper is a review of the certification system required for various energy prosumer business models, including P2P energy trading and participation in small demand response programs, which are based on reliable production and consumption certification. One of the most important parameter in energy trading is ensuring the reliability of trading account balancing. Therefore, we studied to use big data pattern analysis based blockchain smart contract between trading partners to make its tradings are more reliable. For this purpose big data analysis system collected from the IoT AMI and a production authentication system using a private blockchain network linked with the AMI is discussed, using the blockchain smart contract are also suggested. Futhermore, energy trading system concept and business models are introduced.

This paper presents a reinforcement learning framework for stock trading systems. Trading system parameters are optimized by Q-learning algorithm and neural networks are adopted for value approximation. In this framework, cooperative multiple agents are used to efficiently integrate global trend prediction and local trading strategy for obtaining better trading performance. Agents Communicate With Others Sharing training episodes and learned policies, while keeping the overall scheme of conventional Q-learning. Experimental results on KOSPI 200 show that a trading system based on the proposed framework outperforms the market average and makes appreciable profits. Furthermore, in view of risk management, the system is superior to a system trained by supervised learning.

The study revealed that the companies are still reluctant to stop using document-based payment methods although they are aware the use of electronic payment system would reduce express and save time. Considering problems that are suggested in the conventional payment method, more companies will introduce and utilize the electronic payment system. Moreover, as the refined electronic payment system is essential in electronic trade, active studies on this field would greatly contribute to the development of electronic payment system. The prevailing settlement of international trade still relies on trading documents while the legal issues are not finalized for electronic bill of lading (B/L) and electronic bill. This research purpose on comparing some e-trading models in character and presenting the obstacles of e-trading activation and the solutions. e-trading models this research has studied are BOLERO, TradeCard, electronic L/C etc. Comparing characteristic points of the e-trading model in this article are as follows; 1)Access ways as a global e-trading model, 2)Structural and Functional characteristic, 3)Role as a global e-trading model, 5)Legal and Application issues in practice, 6)Security issues for Technology. But Further studies on this subject would be needed.

The level of cultural enjoyment in Korea has improved every year, but the culture that the general public possesses artworks has not developed so much. Most artwork trading systems, from traditional ones to the latest blockchain-based ones, are designed for expensive artwork trading and are hardly accessible to the general public. In this paper, we propose a blockchain-based artwork trading system that can improve the culture of the general public's art collection and contribute to the popularization of fine art. The proposed system consists of three interacted blockchains for identification, artwork registration and smart contract. The proposed system utilizes the advantages of the blockchain system for users to provide trust to each other, and introduces the concept of art notebook for artists to build trust in their own artwork. Since the proposed system builds a trust system through participants rather than experts or external organizations, it can reduce the cost of trading and deal with artworks that can be owned by the general public.

In the legislation interpretation and fundamental viewpoint about the legal system of insider trading, Japan strictly legislate under the proposition, the principle of 'nulla poena,' adopted 'the principle of limited enumeration,' and United states, under 'the principle of comprehension,' has entrusted courts with establishment of concrete concepts and standard, so the courts are very flexible in determining the range of insiders and the importance of inside information to show a strong will to eradicate insider trading. Korea has a legislative position of 'the principle of limited indication' which has been created by the negotiation between those principles of United states and Japan. Though this court has interpreted insider trading, insider trading using non-disclosed information has increased lately, needing the strengthening of its regulations. However, this shows us that sophisticate the regulations may be, the exposure of insider trading has limitations. The most important thing is to change recognition for transparency of the securities market, security of investors and to establish the atmosphere which is that fair stock trading made in a sound capital market to raise funds for corporation. The policies of improving unfair trading, self-regulation bodies, raising the transparency and legality of procedures of supervision and monitoring and applying 'compliance program' to stock companies are very needed to eliminate unfair trading in the securities market and establish the order of trading.

There are many pilot programs and projects to implement the water quality trading (WQT) policy. But actual trading is relatively rare. The main reason of the scarce applications of WQT policy is the difficulty in determining the equalities between the trading sites. The uncertainty of the impacts of the nonpoint sources pollutant discharges between up and downstream urban development areas also makes the implementation of the policy harder. The simulated results from the watershed modeling program will be used to calculate the point and nonpoint sources pollutants of the future urban development scenarios. The amount of suspended sediments resulting from the urban developments and rainfall intensities will be used to indicate the environmental impacts of the water body between upstream and downstream. The water quality impacts after development scenarios to the outlet of the watershed were transferred to the trading units between two sites. The recommended trading units can be used as a decision support system for policy makers and stakeholders to carry out better WQT practices.
