In many parts of the world, the electric power industry is undergoing unprecedented changes. Therefore, in order to reform the electric power industry efficiently and minimize the confusion of this restructuring, the systematic studies related to transmission pricing and transmission cost allocation issues are required essentially. However, even now, the basis of transmission cost allocation rate is not equipped so that the regulation body has determined the allocating rate under the common practice. In this paper, we demonstrate that the decision of transmission cost allocation rate is the regulation body's own right. For this analysis, we apply game theory to the procedure determining this rate and the competition to determine this rate between gencos and distcos is modeled as the arbitration game.

We construct a signaling game model between the arbitrator and claimants, in which the arbitrator's marketing amount is adopted as the signaling device. Assuming that the parties to the dispute select an arbitrator, and if there is a difference in the arbitrator's fee depending on the arbitrator's reputation, the arbitrator will pay to further enhance his reputation. We would like to analyze the cost differences between arbitrators who already have a high reputation and arbitrators who strive to further enhance their reputation using the signal model. From the Analysis of our study, We derive perfect Bayesian equilibrium of the signaling game and refine the equilibrium into a unique equilibrium by invoking the Intuitive Criterion of Cho and Kreps (1987). Further, we characterize the refined equilibrium.

본 연구는 개별기업들이 교역활동과정에서 분쟁이 발생할 경우 국제상사간의 분쟁해결도구로써 중재를 선택하는 이유를 게임이론의 관점에서 구성하였다. 중재에 관한 많은 연구들이 진행되어왔지만 중재를 수요자의 입장에서 살펴본 이론 연구는 드물었다. 본 연구에서 제시된 모형은 기업이 분쟁해결도구를 전략적으로 선택할 수 있다는 전제하에서 중재가 완전베이지언 내쉬균형이 되는 조건을 게임의 대가(payoff)를 비교함으로써 찾아보았다. 이를 통해 알 수 있는 것은 첫째, 중재를 사회의 분쟁해결수단으로 고려할 때 분쟁당사자들의 성향에 대해 고려할 필요가 있다는 점, 둘째 중재를 균형전략으로 만드는 중요한 지표 중의 하나는 중재와 소송의 절대이익이 아닌 두 분쟁해결수단을 통해 기대되는 이익의 상대적인 차이가 중요하다는 점을 보일 수 있었다. 마지막으로 간단한 국제상사의 분쟁사례를 통해 이러한 이론이 어떻게 적용되는지를 살펴보았다.

In many parts of the world. the electricity industry is undergoing unprecedented changes. Hence, in order to reform the electricity industry readily and efficiently and minimize the confusion by these restructuring, it is required the systematic studies related to transmission pricing and transmission cost allocation issues. However, even now the basis of transmission cost allocation rate is not equipped so that the regulation body has determined the allocating rate under the common practice. In this paper it is demonstrated that the decision of transmission cost allocation rate is the regulation body's own right. For the analysis, game theory is applied to the procedure determining this rate and the competition to determine this rate between generators and distributors is modeled as the arbitration game.

Most of the conflict problems between 2 persons can be represented as a bi-matrix game, because player's utilities, in general, are non-zero sum and change according to the progress of game. In the bi-matrix game the equilibrium point set which satisfies the Pareto optimality can be a good bargaining or coordination solution. Under the condition of incomplete information about the risk attitudes of the players, the bargaining or coordination solution depends on additional elements, namely, the players' methods of making inferences when they reach a node in the extensive form of the game that is off the equilibrium path. So the investigation about the players' inference type and its effects on the solution is essential. In addition to that, the effect of an individual's aversion to risk on various solutions in conflict problems, as expressed in his (her) utility function, must be considered. Those kinds of incomplete information make decision maker Bayesian, since it is often impossible to get correct information for building a decision making model. In Baysian point of view, this paper represents an analytic frame for guessing and learning opponent's attitude to risk for getting better reward. As an example for that analytic frame. 2 persons'bi-matrix game is considered. This example explains that a bi-matrix game can be transformed into a kind of matrix game through the players' implicitly cooperative attitude and the need of arbitration.

본고에서는 콘텐츠분쟁조정위원회에서 조정한 사건들을 중심으로 분쟁현황과 그 이슈를 살펴보았다. 그 결과, 미취학 아동들의 모바일 게임 피해 문제, 통신사와 국내 일반기업과 연계된 게임분쟁문제, 게임사의 책임성과 통신사의 주도적인 피해 방지 시스템 구축의 필요성 문제, 업체의 피해 구제 인식의 필요성 문제 등을 되짚어 볼 수 있었다. 또한 본 연구를 통해, 분쟁조정 제도는 분쟁 당사자들의 갈등을 합리적으로 조율하도록 매개 역할을 크게 수행하고 있다는 사실과 모바일 오픈마켓의 자율적인 신뢰성 확립이 절대적으로 필요하다는 사실을 확인할 수 있었다.

본 논문에서는 중첩 된 WBAN(Wireless Body Area Network) 환경에서 비경쟁 전송구간의 신뢰성 있는 전송을 위해 한정된 자원(비경쟁 전송구간)을 각각의 WBAN에게 할당하는 방안을 제안한다. 이를 위해 협동적 게임 이론(cooperative game theory)을 바탕으로 한정된 자원(비경쟁 전송구간)을 효율적이고 공평하게 할당 할 수 있도록 내쉬중재(Nash arbitration) 기법을 통한 자원 할당 방안을 살펴본다. 내쉬중재 협상해법을 통해 WBAN 간 비경쟁 전송구간의 충돌 없이 신뢰성 있는 전송을 보장한다. 또한, 각 WBAN의 비경쟁 전송 구간 내의 디바이스 우선순위와 할당받은 timeslot의 개수를 고려하여 전략 선택에 따른 형평성과 각 WBAN이 비경쟁전송 구간 내에 요구하는 최소한의 timeslot을 보장한다.

The content industries environment has been undergoing significant changes due to rapid technological innovation and content market expansion. Interest in the industry is growing fast both in Asia and Europe. However, in Japan content industries are showing almost zero growth with no increase in overseas expansion. Until now, Japanese content industries have been able to grow based on domestic demands. Many different factors contributed to today's zero growth in Japanese content industries. Two main reasons are: 1) Their lack of interest in overseas expansion and 2) Insufficient investment in domestic human resources development. Considerable amounts of Japanese contents including films, music, games, and animations have been distributed in many Asian countries and today piracy problems in the region are at a serious level. According to 2004 records pirated editions accounted for 85%, 16%, 19%, and 36% in China, Korea, Hong Kong, and Taiwan respectively. Pirated editions bring economic losses to Japanese copyright profits. Making it worse, they weaken the motivation to create content and make it hard to activate cultural exchanges. Losses from copyright violations in Japanese content industries are expected to keep increasing in the future. In order to make Japan competitive and grow it is crucial to take proper measures to protect copyright infringements. This study considers the current situation of the Japanese content market, infringement issues in content which is causing many problems in Asian countries, including China, and facts about losses caused by this problem.

Purpose : The purpose of this study is to evaluate the effects of virtual reality based exercise program on gross motor function and balance of children with spastic cerebral palsy. Method : Subjects of this study, among the children who received the diagnosis spastic cerebral palsy, for children total of 8 people have agreed to research. Experimental group 4 people, control group 4 people, was a total of 8 people. Group-specific arbitration method, was applied to Nintendo Wii Fit game (experimental group) and exercise program (control group). Each training courses 30 minutes for 4 weeks, examined the changes in Gross Motor Function Measure(GMFM) and Pediatrics Balance Scale(PBS) ability to examine a total of 4-week course effectively. The intervention were compared by measuring before and after. Result : There were significant improvements in the subscales of the gross motor function and balance test of those who practiced with the Nintendo Wii Fit game, while the control group showed no significant changes. Conclusion : Therefore, the virtual based on exercise is effective in improvement of to improve the gross motor function and balance in children with spastic cerebral palsy.
