Maglev vehicles levitated and propelled by electromagnet as non-contact between vehicle and guide rail is environmentally friendly transport system which have many advantages like ride comfort and guide way construction costs. As a goal of commercial operation at Incheon International Airport in 2012, development of vehicle is underway and proto-vehicle is test running at KIMM. The maglev bogie system of proto-vehicle, like railway vehicle, has functions to support weight of vehicle, transfer force of brake and propulsion and improve ride comfort through insulation of vibration and improve curve negotiation capability. The main components of a bogie are two modules consisted of electromagnetic, frame and linear motor, two tie beams to connect two modules and steering system to improve curve negotiation capability. The purpose of this paper is to describe general specification, structure, manufacturing process, performance testing, ride comfort of proto-vehicle and bogie system.

Dispute plays a key role in maintaining the desirable performance of trade transaction. In an effort to stay competitive in a global marketplace, the Korean companies need to become more aware of alternatives to costly and time-consuming litigation. Korean companies, therefore, should be more concerned with ADR(Alternative Dispute Resolution) system and should utilize ADR to settle their disputes effectively and efficiently. ADR encompasses all process of dispute resolution as a substitute for the traditional litigation. Generally, three kinds of ADR are available in Korea: Negotiation, mediation, and arbitration. This article investigates reasons why ADR isn't used well in Korea and suggests ways how ADR can work best in international trade disputes. To expand ADR system in international trade disputes, it is very important for both the company and the scholar to recognize the concept and usefulness of ADR system. The Korean Commercial Arbitration Board also must help both Korean companies and scholars recognize the mechanism of dispute resolution and utilize ADR system in international trade disputes.

Automatic vessel collision-avoidance systems have been studied in the fields of artificial intelligence and navigation for decades. And to facilitate automatic collision-avoidance decision-making in two-vessel-encounter situation, several expert and fuzzy expert systems have been developed. However, none of them can negotiate with each other as seafarers usually do when they intend to make a more economic overall plan of collision avoidance in the COLREGS-COST-HIGH situations where collision avoidance following the International Regulations for Preventing Collisions at Sea(COLREGS) costs too much. Automatic Identification System(AIS) makes data communication between two vessels possible, and negotiation methods can be used to optimize vessel collision avoidance. In this paper, a negotiation framework is put forward to enable vessels to negotiate to optimize collision avoidance in the COLREGS-COST-HIGH situations at open sea. A vessel vector space is defined and therewith a cost model is put forward to evaluate the cost of collision-avoidance actions. Negotiations between a give-way vessel and a stand-on vessel and between two give-way vessels are considered respectively to reach overall low cost agreements. With the framework proposed in this paper, two vessels involved in a COLREGS-COST-HIGH situation can negotiate with each other to get a more economic overall plan of collision avoidance than that suggested by the traditional collision-avoidance expert systems.

Among the P2P based multimedia streaming architecture, multiple chain architecture has advantage in adapting to dynamically changing network topology simply and rapidly, so this architecture is used for UCC broadcasting system. In UCC broadcasting system, general peer involved in DSLAM becomes UCC server rather than broadcasting system that transfers data from ISP servers. Therefore UCC data generated from UCC server peers is transmitted to peers through DSLAM, and this transmission uses uplink bandwidth of DSLAM. In this paper, I propose an efficient management method of DSLAM uplink bandwidths through negotiating tracker and UCC server peer or head peers of DSLAM. I propose the method that tracker restricts a bitrate of uplink stream of UCC servers when used uplink bandwidth of DSLAM exceeds a certain point of maximum uplink bandwidths. I will show the improved performance of proposed scheme rather than general method with respect to the uplink bandwidth of DSLAM by numerical analysis and simulation.

As the size and complexity of network increase Distributed System Management (DSM) will be significant issue within information network in order to increase the high reliability and to improve the flexibility of network management. The OSI management model has several problems. The key problems are that it does not fully address the problem of how to develop communication protocol in support of DSM and how to classify the management connection criteria. In this paper to solve first problem described above this paper propose the connectionless CMIP to accomplish for effectively managing the distributed management managing systems to handle the dynamic informations. To work out second problem we introduce the connection criteria in the hierarchy of management system and finally evaluate the efficiency of a suggested protocol during cooperative negotiation among the managing system.

The sales activity of most of small manufacturing companies is based on orders of buyers. The process of promotion, negotiation, receipt and selection of orders of the manufacturers is closely coupled with the load status of the production lines. The decision on whether to accept an order or not, or the selection of optimal order set among excessive orders is entirely dependent on the schedule of production lines. However, in the real world, since the production scheduling activity is mainly performed by human experts, most of small manufacturers are suffer from being unable to meet due dates, lack of rapid decision on the acceptance of new order. Recently, Internet based Electronic Commerce is recognized as one of the alternatives for strengthening sales power of small and medium companies. However, small and medium manufacturers can't adjust properly to the new environment because they are in short of money, personnel, and technology. To cope with this problem, this paper deals with development of part sales agent coupled with virtual manufacturing in Internet environment that consist of selection agent, advertisement agent, selection agent, negotiation agent, and virtual manufacturing system. This paper develops a time-bounded negotiation mechanism for small and medium manufacturers in agent-based automated negotiation between customers and negotiation agents. Furthermore, to select optimal order set maximized profit, we first formulate the order selection problem with mixed integer programming, but the computation time of IP is not acceptable for real world scale problem. To overcome this problem and dynamic nature of virtual manufacturing, we suggest a genetic algorithm approach, which shows a reasonable computation time for real world case and good incremental problem solving capability.

In an effect to composite an optimal supply chain, this study has introduced an agent-based negotiation as a method to assign a lot of orders to a large number of participants. As a resources allocation mechanism to form a strategic cooperation based on information sharing between supply chain members(buyers, manufacturers, suppliers), this agent negotiation provides coordination functions allowing all participants to make a profit and accomplishing Pareto optimum solution from the viewpoint of a whole supply chain. A SET model-based scheduling takes into consideration both earliness production cost and tardiness production cost, along with a competitive relationship between multiple participants. This study has tried to prove that the result of an agent-based negotiation is a Pareto optimal solution under the dynamic supply chain environment, establishing the mathematical formulation for a performance test, and making a comparison with the heuristic Branch & Bound method.

Korean medical fee contract system between the insurer and healthproviders was introduced in 2000. However, a continuous discord among contracting parties concerned and an irrational operation of an arbitration committee of Ministry for Health, Welfare and Family Affairs (MIHWAF) have made it difficult for them to reach to an agreement over last 8 years. The purpose of this study is to observe the current problems of contract system from the view of health insurance law and actual examples. Furthermore, I examined the of breakdown of negotiation by analyzing the eligibility of contracting parties, rationality of Resource Based Relative Value System (RBRVS) and contracting method and fairness of arbitration method in case of negotiation rupture. The results were as follows: First, since the introduction of medical fee contract system, there has been a problem in that both the president of National Health Insurance Corporation (NHIC) and health care provider association have not held strong negotiation power. Second, the frequent changes and notifications of Relative Value Units (RVUs) without any mutual consent between the insurer and provider association negatively have influenced the conversion factors and finally hindered the agreement of contract. Third, a current process that the conversion factors are mediated and determined at the arbitration committee of MIHWAF in the case of contract breakdown between contracting parties has some flaw in that the irrational composition of committee provoked the lack of fairness and objectivity of mediation. Fourth, we can not prospect a satisfactory outcome of arbitration committee because the mediation always has failed to proceed smoothly due to boycott of both committee members from insurer and providers over last 8 years. As a result, we have to make an every effort to resolve problems mentioned above and then dream of an advanced national health insurance system.

본 연구에서는 부서간 갈등을 해결하기 위한 새로운 방법으로서 웹 기반 협상지원시스템(Web-based Negotiation Support System: Web NSS)을 제안한다. 기업의 경영활동에 있어서 각 부서간에는 여러 가지 이유로 인해 갈등이 존재한다. 대표적으로 생산부서와 마케팅 부서간에는 갈등이 항상 존재하기 마련이다. 예를 들어, 마케팅 부서에서는 수시로 변하는 고객들의 요구사항에 맞추기 위해서 제품라인을 확대하여 다양한 제품들을 생산하고, 그에 따른 높은 판매실적을 원한다. 그러나, 생산부서에서는 이와는 달리 적은 종류의 제품을 가능한한 한정적으로 생산하여 제품에 들어가는 원가를 절감하고 그에 따라서 생산실적을 높이려고 한다. 이같은 유형의 부서간 갈등은 결과적으로 기업의 전체적인 성과를 저해시키는 요인으로 작용한다. 또한, 최근 대부분의 기업은 각각의 부서별 기능을 분산형태로 운영하고 있어서 관련부서가 지리적으로 멀리 떨어져 있게 되어 새로운 의사결정통합 지원시스템이 절실히 요구된다. 본 연구에서는 이러한 상황에 적합한 새로운 유형의 갈등관리 메커니즘으로서 웹 기반 협상지원시스템을 제안한다. 본 시스템은 생산부서와 마케팅 부서간의 갈등을 해결하고 이를 협상의 형태로 지원하기 위한 웹 기반 의사결정지원시스템이다. 본 연구에서는 실험과정을 통하여 제안하는 의사결정지원시스템의 성과를 증명하였다.
