  • Collisions between tags greatly reduce the identification speed in radio frequency identification (RFID) systems and increase communication overhead. In particular for an active RFID system, tags are powered by small batteries, and a large number of re-transmissions caused by collisions can deteriorate and exhaust the tag energy which may result in missing tags. An efficient collision-free arbitration protocol for active RFID systems is proposed in this paper. In this protocol, a new mechanism involving collision detection, collision avoidance, and fast tag access is introduced. Specifically, the pulse burst duration and busy-tone-detection delay are introduced between the preamble and data portion of a tag-to-reader (T-R) frame. The reader identifies tag collision by detecting pulses and transmits a busy tone to avoid unnecessary transmission when collision occurs. A polling process is then designed to quickly access the collided tags. It is shown that the use of the proposed protocol results in a system throughput of 0.612, which is an obvious improvement when compared to the framed-slotted ALOHA (FSA) arbitration protocol for ISO/IEC 18000-7 standard. Furthermore, the proposed protocol greatly reduces communication overhead, which leads to energy conservation.

  • In the IEEE 802.16 Wireless MAN standard, the best effort service class is ranked on the lowest position in priority and is assisted by a MAC scheme based on reservation ALOHA. In such a MAC scheme, a collision among the requests is unavoidable so that the standard adopted a binary exponential back-off rule to arbitrate a collision. Aiming at improving throughput performance, we present two generic collision arbitration rules based on p-persistence rule, (identified as pristine and metamorphosed rules), as alternatives in a wireless MAN. For each of these rules, we then develop an analytical method to calculate an approximate value of saturated throughput. In comparison with simulation results, we confirm the high accuracy of the analytical method. Also, the pristine and metamorphosed rules are observed to exhibit higher saturated throughput compared with the binary exponential back-off rule.

  • This paper is to analyze the legality in which the fraud rule allow the issuer of L/C or a court to disrupt the payment to the beneficiary under the deferred payment credit when the nominated bank for deferred payment undertaking made prepayment or negotiation before the maturity date and fraud is identified to be involved. Since the function of commercial L/C is to provide absolute assurance of payment to a beneficiary, the fraud rule based on fraud exception has been known as the negative factor which lead to the disruption of "principle of independence & abstraction" under the commercial L/C transactions. As a result, the fraud rule is necessary to limit the activities of fraudsters, but its scope must be carefully circumscribed so as not to deny commercial utility to an instrument that exists to serve as an assurance of payment. But the fraud itself has not been firmly established because it is inherently pliable in its concept. There are numerous contents to describe the application of fraud to the L/C transactions as a standard such as egregious fraud, intentional fraud, L/C fraud(omitted here), flexible fraud, and constructive fraud. And so the standard applicable to the commercial transaction as the fraud rule would be high or low depending upon the various standards of fraud.

  • India is a gigantic market with a population of 1.2 billion and an economy that is growing at the second-fastest pace in the world. The volume of trade between India and Korea has been sharply increased with the increase of dispute since 2000. Although avoidance of disputes is always a priority, it is also important to prepare methods of dispute resolution which are efficient and economical. So, understanding of Indian dispute resolution system is a necessary requirement for successful business operation with Indian companies. This article analyzed and compared with the various ways of Indian ADR such as negotiation, mediation, conciliation, Lok Adalat and arbitration in order to help the Korean traders who enter into business with the Indian companies to settle their disputes efficiently. In conclusion, this article suggests the following ways to overcome problems of dispute with Indian companies: First, the Korean companies should recognize the characteristics of Indian ADR Ways respectively. Second, the Korean companies should utilize the conciliation or the mediation in small claim but arbitration in large claim. Third, Write a contract and insert the KCAB's standard arbitration clause in their contract.

  • The World Trade Organization (WTO) offers remedies for non-compliance by the introduction of compensation or retaliation in the Dispute Settlement Understanding (DSU). There are no the provisions under the WTO DSU and it seems unclear what retaliation is attempting to achieve. Therefore, it is unclear whether the goal of WTO retaliation is to induce compliance or to restore the balance between the rights and the obligations of WTO members. It has been claimed the WTO has a strong dispute settlement system by providing retaliation when the recommendations and rulings of Dispute Settlement Body (DSB) are not complied with. But this seems to be inadequate to bring about effective and timely compliance. Especially there is a problem with free riding by a violating member because the level of retaliation is determined from the expiration of a reasonable period of time, providing an incentive to delay compliance. Also the level of the suspension of concessions or other obligations authorized by the DSB is equivalent to the level of nullification or impairment, according to DSU Article 22.4. However, if the member concerned objections to the level of the suspension proposed, the matter shall be referred to arbitration. The arbitrator shall not examine the nature of the suspension of concessions or other obligations to be suspended but shall determine whether the level of such suspension is equivalent to the nullification or impairment. The arbitrator makes an assessment standard of equivalence by comparing the suspension of concessions or other obligations and the nullification or impairment calculated in terms of the amount of trade. But it is necessary that other standards replace the quantitative standards when the level of the nullification or impairment cannot be quantified by concrete damages.

  • World Trade Organization(WTO) has 164 members since it has established on 1995. It plays a significant role in solving the world trade disputes. The process of the dispute settlement mechanism includes five steps: Negotiation, Establishment of experts group, Deliberation of appellate body, Execution and Supervision of Verdict and the Sanctions for Default. It suggested that the higher rate of developed countries using mechanism to solving the disputes than developing countries solving disputes by mechanism through the analysis of dispute of WTO members. Meanwhile, the more powerful economic entity is, the more trade dispute will be. There are several problems of mechanism by analysis the recently famous cases of trade disputes: Overburden of experts panel, Low utilization rate of the mechanism of developing countries, Lack of economic competition policy and labor standard terms and Unfulfillment of retaliatory measures of developing countries towards developed countries. This paper propose proper solutions and advises to improve mechanism of WTO dispute settlement.

  • Franchising has proved over many years to be a successful commercial vehicle for the international distribution of products and services. However, there has long been missing a user-friendly model contract that would reflect the diversity of international franchising contracts. Because the ICC has drafted a model form of international franchising contracts, taking into account the most commonly encountered clauses in franchising agreements, their model could be used as a checklist of the core obligations of a cross-border franchise contract. Because there is no internationally agreed-upon uniform legislation on franchising, parties must rely on national laws and regulations applicable to the international franchise (when such laws and regulations exist) and should therefore very carefully draft stipulations for the legal status of the contract. This study has been intended to cite some provisions for striking a fair balance between the interests of the franchisor and those of the franchisee and for avoiding unfair trade acts in international franchising contracts.

  • As women's social advance had accomplished improvements to standard of living and equal employment, new forms of dispute such as gender inequality, sex crimes, and divorce rate increases have begun to generate. Disputes between men and women are desirable to settle by ADR rather than by traditional litigation owing to difficulties of legal resolution, cost and time, need for amicable dispute, etc. This study aims to reveal whether there is a relationship between ADR and gender. Through review of previous articles, this study finds that gender difference makes a visible difference depending on case type, context, and sex role of participants. For example, women were selected as mediators and arbitrators in non-monetary and small-claims disputes, family, labor, and consumer disputes and men were selected in large-scale disputes and construction, corporate and commercial, and intellectual property disputes owing to differences of experience and professionalism. Women were relatively frequently selected as mediators owing to active communication skills and men were selected as arbitrators because of decision-making skills.

  • With the Korea-China FTA negotiations currently on the line, the importance of research into the FTA dispute settlement system has been increasing. In this paper, a comparison of Korea and China's FTA dispute settlement agreements concluded with ASEAN is contemplated, and implications for the future of the Korea-China FTA have been suggested. The FTA dispute settlement agreements with ASEAN concluded by both Korea and China provide perspectives on both sides. This agreement with ASEAN also provides a standard for the potential Korea-China FTA agreement. Specifically, the basis of these agreements with ASEAN is the same, although there are clear distinctions, described in a more detailed manner. A problem arises when there has been no discussion on dispute settlement agreements in Korea, especially of the agreement with ASEAN, whereas the opposite is true of the China counterpart. In this paper, Chinese academic FTA dispute settlement agreement studies have been also examined.
