Since the Arbitration Law of China took effect in 1995, arbitration has grown with the economy. At the end of 2009, there were 202 arbitration institutions in China. Among them, China International Economic and Trade Arbitration Commission(CIETAC) has adopted online arbitration and has settled internet domain name disputes since 2001. CIETAC Domain Name Dispute Resolution Center(DNDRC) has accumulated abundant experiences of online arbitration in the field of domain name disputes. Based on those experiences, on 1 May 2009, CIETAC implemented the CIETAC Online Arbitration Rules(Rules') to regulate the resolution of e-business disputes as well as other business disputes. With this background, this article aims to study the status quo, practices and issues of online arbitration conducted by CIETAC. For the purpose of the article, a general picture of online arbitration is outlined first, followed by introducing the steps of the online arbitration procedure. According to the 'Rules', the entire arbitration process is conducted using online communication methods which are cost-effective and efficient. To facilitate the development of online arbitration, legal barriers need to be removed. This article considers main legal issues of online arbitration in China and proposes amendment to Chinese Arbitration Law, in particular, the recognition of the validity of electronic arbitration agreements and awards.

In this paper we introduce the Internet-based purchase support systems using data mining and case-based reasoning (CBR). Internet Business activity that involves the end user is undergoing a significant revolution. The ability to track users browsing behavior has brought the vendor and end customer's closer than ever before. It is now possible for a vendor to personalize his product message for individual customers at massive scale. Most of former researchers, in this research arena, used data mining techniques to pursue the customer's future behavior and to improve the frequency of repurchase. The area of data mining can be defined as efficiently discovering association rules from large collections of data. However, the basic association rule-based data mining technique was not flexible. If there were no inference rules to track the customer's future behavior, association rule-based data mining systems may not present more information. To resolve this problem, we combined association rule-based data mining with CBR mechanism. CBR is used in reasoning for customer's preference searching and training through the cases. Data mining and CBR-based hybrid purchase support mechanism can reflect both association rule-based logical inference and case-based information reuse. A Web-log data gathered in the real-world Internet shopping mall is given to illustrate the quality of the proposed systems.

Pairs trading is a type of arbitrage investment strategy that buys an underpriced security and simultaneously sells an overpriced security. Since the 1980s, investors have recognized pairs trading as a promising arbitrage strategy that pursues absolute returns rather than relative profits. Thus, individual and institutional traders, as well as hedge fund traders in the financial markets, have an interest in developing a pairs trading strategy. This study proposes pairs trading rules (PTRs) created from a price ratio between securities (i.e., stock index futures) using rough set analysis. The price ratio involves calculating the closing price of one security and dividing it by the closing price of another security and generating Buy or Sell signals according to whether the ratio is increasing or decreasing. In this empirical study, we generate PTRs through rough set analysis applied to various technical indicators derived from the price ratio between KOSPI 200 and S&P 500 index futures. The proposed trading rules for pairs trading indicate high profits in the futures market.

The Korean Conflict of Laws Act recently incorporated much of the European Union's recent revision in "EC Convention on the Law Applicable to Contractual Obligations (Rome 1980)"(hereinafter Rome Convention). With the revision of Rome Convention applied to contractual obligations,"Regulation (EC) No 593/2008 of the European Parliament and of the Council of 17 June 2008 on the law applicable to contractual obligations (Rome I)"(hereinafter Rome I) has taken effect on December 2009. Before the effectivation of Rome I, "Regulation (EC) No 864/2007 of the European Parliament and of the Council of 11 July 2007 on the law applicable to non-contractual obligations (Rome II)"(hereinafter Rome II) has come into effect on January 2009. This means the revision of certain rules and its practical implications need an in-depth study on governing law rules under Rome I which provides newly effected governing laws applicable to contractual obligations. Moreover, uniform choice of law rules on non-contractual obligations needs to focus especially on marine insurance contract. Where policy assignment and subrogation causes, how to decide the governing law which will be applied to the insurer as a third party? This article attempts to analyze emerging legal issues in legal regimes determining choice of law, especially those in international marine insurance contracts. This will help Korean practitioners to be dialed in legal affairs under English Law as the governing law in their contracts.

Purpose - The purpose of this study was to expound the packaging framework system(PFS) under international trade rules. Design/methodology/approach - This study analyzed packaging framework system and packaging regulations and technical standards in international regulations and major countries and classified these in some standards Findings - First, the study provides packaging provisions associated with packaging regulations and technical standards (PRTS). Then, the basis of PFS in international trade rules was proposed; it is believed that the PFS was composed of packaging legal system in WTO institutional framework (WTO-PLS), international organization packaging standard system (IO-PSS) and major countries or regions packaging regulatory system (MCR-PRS). Secondly, this paper expounded relations and legal characteristics of the three packaging systems. Finally, This study investigated PRTS coverage under technical barriers to trade (TBT) and Sanitary and Phytosanitary measures (SPS). Research implications or Originality - The regulations associated with PRTS have played a key role in challenges to merchandise trade in international trade. This study has significance in classifying packaging related reticulations into several criteria unlike previous studies. Therefore it is hope that this study can provide a supplementary document for the existing research of PRTS.

Tourism and hospitality have encountered significant changes in recent years as a result of the rapid development of information technology (IT). Customers now expect more expedient services and customized travel experiences, which has intensified competition among service providers. To meet these demands, businesses have adopted sophisticated IT applications such as ChatGPT, which enables real-time interaction with consumers and provides recommendations based on their preferences. This paper focuses on the AI support-prompt middleware system, which functions as a mediator between generative AI and human users, and discusses two operational rules associated with it. The first rule is the Information Processing Rule, which requires the middleware system to determine appropriate responses based on the context of the conversation using techniques for natural language processing. The second rule is the Information Presentation Rule, which requires the middleware system to choose an appropriate language style and conversational attitude based on the gravity of the topic or the conversational context. These rules are essential for guaranteeing that the middleware system can fathom user intent and respond appropriately in various conversational contexts. This study contributes to the planning and analysis of service design by deriving design rules for middleware systems to incorporate artificial intelligence into tourism services. By comprehending the operation of AI support-prompt middleware systems, service providers can design more effective and efficient AI-driven tourism services, thereby improving the customer experience and obtaining a market advantage.

Business processes are often of long duration, and include internal worker's decision making, which makes business processes to be exposed to many exceptional situations. These properties of business processes makes it difficult to guarantee successful termination of business processes at the design phase. The behavioral properties of business processes mainly depends on the data aspects of business processes. To formalize the data aspect of process modeling, this paper proposes a graph-based model, called Data Dependency Graph (DDG), constructed from dependency relationships specified between business data. The paper also defines a mechanism of describing a set of mapping rules that generates a process model semantically equivalent to a DDG, which is accomplished by allocating data dependencies to component activities.
