As Electronic Commerce(EC) has been emerged and has developed, many researchers have tried to establish EC framework for automated contract and negotiation using agent technologies. Traditional researches, however, often had limitations. They often enforced the user's participations during the automated contract process of agents. They also could only consider a few of the user's requirements for a specific goods and did not have supported the procedures and methodologies for making the best contract. In this paper, we propose business model on EC based on multiagents to overcome the defects of the previous researches. We apply CSP techniques to brokerage process to satisfy various preferential requirements from the user. We also propose efficient negotiation mechanism using negotiation model of game theory. The contract candidates automatically negotiate and mediate in terms of their benefits through the proposed negotiation mechanism. For the optimal brokerage and automated negotiation, the agents process activities for contract on three layers, which are called competition layer, constraint satisfaction layer and negotiation layer in the proposed model. We also design the message driven communication protocol to support the automated contract among the agents. Finally, we have implemented prototype systems applying the proposed model and have shown the various experimental results for efficiency of the proposed model.

In terms of realizing the future e-government such as intelligent government, this paper attempts to provide an earnest and insightful reflection and suggests desirable strategies with regard to the four different crucial elements including electronic voting, electronic contract, resident registration/electronic document management, and real-estate registration as an operating strategy of intelligent government and the fourth industrial revolution regarding. The 4th industrial revolution is aimed at concentrating information or data characterized with sharing, opening, communicating and releasing in cloud computing system, analyzing big data, collecting information, and flourishing people's well-being by information and communications technology with utilizing the smart devices. Therefore, reliability of the pivotal information or data is critical and it is important for the participants being transparently shared, without the data or information being forged. In this respect, introduction or application of block chain technology is essential. This paper will review preceding studies, discuss the aspect of the 4th industrial revolution and intelligent government, then suggest operating strategies in the field of electronic voting, electronic contract, management of resident registration and electronic document and real-estate registration.

The expansion of regionalism has resulted in the creation of blocs of the world economy, so that those countries not belonging to one or more blocs can discriminated. Though recently singed on the bill of FTA with Chile, Korea is actually alienated from major stream of the blocs. Therefore, Korea government makes efforts to contract more FTAs with countries such as Singapore and Japan. FTA is believed to be an important method to secure export and national competitiveness in the long term. Therefore, we need to exactly understand critical issues and the long-run effect of FTA. The paper tries to find out important issues and potential strategies relating to electronic commerce in Korea-Singapore and Korea-Japan FTA.

This paper deals with the implementation of electronic voting system using permissioned block chain technology. Cases studies have recently been under way in many industrial areas to review the application of the blockchain based electronic voting system. The existing electronic voting system was easily exposed by hacking because of its centralized characteristics, making it difficult to ensure the reliability and transparency of the voting system itself. In this study, we proposed key considerations and concepts to ensure the reliability and transparency of voters and voting stakeholder by utilizing a hyperledger fabric which is nowadays widely used as a permissioned blockchain.

Second, traditionally international payment systems such as letters of credits, remittance, documentary collections and open account have been operated as an important and popular method of payment. In the modern world of electronic commerce, information technology has made it possible to pay for the sale of goods and services over the internet. The payment methods such as Credit Card, Debit Card, Electronic Cash, Electronic Fund Transfers enable partly sellers, buyers and service providers to settle payment electronically through the internet. To settle the problems of payment systems, the security requirements for safe electronic Payments such as authenticity, integrity, non-repudiation have to be guaranteed.

"UNIDROIT Principles 2004" focused on an enlargement rather than a revision. An additional Section or Chapter so to speak, which are about, the Authority of a Agents, Third Party Rights, Set-off, Assignment of Rights, Transfer of Obligations and Assignment of Contracts, and Limitation Periods have been added, while the only change of substance made to the 1994 Edition, apart from two paragraphs in the Preamble, and three new provisions in Chapter 1 and 2 which are necessary to adapt the Principles to the needs of electronic contracting. The Principles which have the nature of the restatement of international uniform laws (for example CISG) are continuous exercise. Therefore we should note whether in the future our concerns would be on a additional topics on a improvement of the current text by monitoring the reception of the "UNIDROIT Principles 2004" in practice, and the application by contracting parties. The purposes of the Principles may be classified into three ; the rules of law governing the contract, means of interpreting and supplementing international uniform law or domestic law, or models for national and international legislator. Among them, the function of governing law may be applied by the express choice by the parties or by the implied choice like "general principles of law" or "les mercatoria", and it may be applied in the absence of any choice of law by the parties. Among there importance functions, this writer would like to emphasize the function to supplementing international uniform law instruments. The reason is that the CISG which has been established as an international uniform sales act and to which our country would be a contracting State from March, 2005, needs a lot of gap-filling. For this purpose it is advisable the parties to insert following provisions in their contract. "This contract shall be governed by the CISG, supplemented when necessary by the UNIDROIT Principles 2004" Thus success in practice of the UNIDROIT Principles over the last then years has surpassed the most optimistic expectations. It is hoped that the 2004 Edition of the UNIDROIT Principles will be just as favorably received by legislators, business persons, lawyers, arbitrators and judges and become even better known and more widely used throughout the World.
