The rapid change in gold price is an issue of concern in the global economy and financial markets. Gold has been used as a means for trading and transaction around the world for long period of time and it plays an integral role in monetary, business, commercial and financial activities. More importantly, it is used as economic measure for the global economy and will continue to play an important economic vital role - both locally and globally. There has been an explosive growth in demand for efficient and effective scheme to predict gold price due its volatility and fluctuation. Hence, there is need for the development of gold price prediction scheme to assist and support investors, marketers, and financial institutions in making effective economic and monetary decisions. This paper primarily proposed an intelligent based system for predicting and characterizing the gold market trend. The simulation result shows that the proposed intelligent gold price scheme has been able to predict the gold price with high accuracy and precision, and ultimately it has significantly reduced the prediction error when compared to baseline neural network (NN).

Payment system is defined as the various contracts and operating facilities for the transfer of monetary value to clear the relationship between credit and debt. Payment systems essentially require the efficient and reliable operations. Card-based payment systems are developed practically and creatively in accordance with the progress of ICT. Especially in mobile environment with intelligent mobile devices such as smart-phones and tablets, a variety of payment services are provided. Existing card-based payment services are configured by the payment transaction initiated by the merchants card acceptance and then swiping into the CAT (Card Authorization Terminal) to begin the transaction. The merchant initiated payment services are now applied to the Wireless CAT (W-CAT) for mobile environment. That kind of payment services cause many problems such the illegal card information leaks and the lingering threat of W-CAT theft. Also, the use of many W-CATs increased cost to the merchant. In this paper, we propose the card holder initiated card payment system using the intelligent mobile devices in mobile environment for solving problems of the existing merchant initiated card payment system and coping effectively with the activation of a wireless data network and changes of information technology.

Purpose - Recently, the Korean government is seeking to internationalize KRW and reduce its heavy reliance on the U.S. dollar and better cope with risks from external turbulence. However, there has been too little study on this subject in comparision with its importance. The main objective of the paper is to distinguish the descrete stages of the KRW internationalization and recognize the costs and benefits of each stage. Research design, data, methodology - In order to achieve its goal, this study accomplishes a formal policy analysis based on potential factors of currency internationalization and an examination of legal practices in relation to Foreign Exchange Transaction Regulation (the Regulation). Results - This study found that securing monetary policy may not be easy under liberalized capital account for a small open economy like Korea in view of the trillema. In addition, the inherent ambiguity of the Regulation may increase the costs of KRW internationalization. Conclusions-This study revealed the negative system for the control of foreign exchange of the Korean government. The excessive regulatory restrictions on foreign exchange may hinder the process of KRW internationalization. Some legal and policy reforms are needed to improve related regulation and infrastructure.

Nowadays, an open-market which provides sellers and consumers a cyber place for making a transaction over the Internet has emerged as a prevalent sales channel because of convenience and relatively low price it provides. However, there are few studies about CRM strategies based on VIP consumers for an open-market even though understanding VIP consumers' behaviors in open-markets is important to increase its revenue. Therefore, we propose CRM strategies targeted on VIP customers, obtained by analyzing the transaction data of VIP customers from an open-market using data mining techniques. To that end, we first defined the VIP customers in terms of recency, frequency and monetary (RFM) values. Then, we used data mining techniques to develop a model which best classifies and identifies infiluential factors customers into VIPs or non-VIPs. We also validate each of promotion types in the aspect of effectiveness and identify association rules among the types. Then, based on the findings from these experiments, we propose strategies from the perspectives of CRM dimensions for the open-market to thrive.

This research investigates the rising new role of mileage system as private e-money in a exploratory study. The key research questions are "How does mileage system evolve with expansion of e-business and what are the cases for real experiences in 'money-like' mileage and their implications?" This research focuses on the proposition that mileage points created in commercial transactions as a royalty program are observed to serve a new role as payment tool. In an attempt to identify factors that determine mileage system as private money, we employ three factors: confidence, transaction cost, and monetary freedom. Also, this research proposes a direction for further research and follow-up studies to establish legal and institutional issues and the relevant architecture, all of which are essential elements to make the mileage points global money with a certain trade ratio in the near future.

Large access providers (ISPs) are seeking for new types of business agreements and pricing models to manage network costs and monetize better the provision of last-mile services. A typical paradigm of such new pricing norms is the proliferation of paid peering deals between ISPs and content providers (CPs), while on top of this, some ISPs are already experimenting with usage-based tariffs, usually through data-plans, instead of the typical fixed-based charging. In this work we define as common platform, the infrastructure in which a single ISP transacts with several CPs through peering agreements. In this context, we examine whether, and under which market conditions, the profitability of the involved stakeholders improves when the establishment of this platform is accompanied by a monetary compensation from the CPs to the ISP (paid peering), v.s. a scenario where their deal is a typical settlement-free one. In both cases, we assume that the ISP implements a usage-based access pricing scheme, implying that end-users will pay more for higher transaction rates with the CPs. Our framework captures some of the most important details of the current market, such as the various business models adopted by the CPs, the end-users' evaluation towards the ISP's and CPs' level of investments and the traffic rates per transaction for the offered services. By analysing the equilibrium derived by a leader-follower game, it turns out (among other practical takeaways) that whether or not the profitability of a CP improves, it highly depends on whether its business model is to sell content, or if it obtains its revenue from advertisements. Finally, we extract that consumer surplus is considerably higher under paid peering, which in turn implies improved levels of social welfare.

블록체인 기술은 거래를 투명하게 관리함으로써 중앙통제 없이 신뢰 가능한 P2P 거래를 가능하게 한다. 최근에는 금전적 가치를 지닌 선하증권(Bill of Lading, B/L서류)의 무결성을 확보하기 위해 블록체인을 적용한 연구가 진행되고 있다. 본 논문에서는 사용성 개선을 위한 블록체인 기반의 선하증권 시스템을 제안한다. 수출자는 선사로부터 발급 받은 선하증권을 블록체인에 저장하고, 은행에서 이를 조회하여 신용장 거래를 수행한다. 수입자는 선하증권 서류의 지문이 담긴 QR코드(Quick Response code)로 신원증명을 완료한 뒤 화물을 인도 받게 된다. 수출자는 우편으로 보낼 시간과 비용을 절약하고, 물품의 보안을 강화할 수 있다는 점에서 큰 효과를 거둘 수 있다. 수입자의 경우 선적 서류가 블록체인 네트워크에 등록되자 마자 서류를 열람할 수 있고, 신뢰를 바탕으로 거래를 수행할 수 있다는 이점을 갖는다. 뿐만 아니라 은행에서는 선적서류에 대한 검증을 더욱 신속하게 수행할 수 있다.
