  • In this paper, we propose a new congestion control scheme for high-speed networks. The basic idea of our proposed scheme is to adopt a game theory called, "Minority Game" (MG), to realize a selective reduction of the transmission speed of senders. More concretely, upon detecting any congestion, the scheme starts a game among all senders who are participating in the communication. The losers of the game reduce the transmission speed by a multiplicative factor. MG is a game that has recently attracted considerable attention, and it is known to have a remarkable property so that the number of winners converges to a half the number of players in spite of the selfish behavior of the players to increase its own profit. By using this property of MG, we can realize a fair reduction of the transmission speed, which is more efficient than the previous schemes in which all senders uniformly reduce their transmission speed. The effect of the proposed scheme is evaluated by simulation. The result of simulations indicates that the proposed scheme certainly realizes a selective reduction of the transmission speed. It is sufficiently fair compared to other simple randomized schemes and is sufficiently efficient compared to other conventional schemes.

  • DCF (Distributed Coordination Function)는 송신노드들이 경합 윈도우 중에서 임의로 송신 대기 시간을 결정함으로써 노드 사이의 채널 경합을 분산적으로 해결한다. 그러나 경합 윈도우의 최대 크기는 제한적이므로 송신 노드의 수가 많아지는 경우 송신 충돌 확률이 증가한다. 본 논문에서는 이와 같은 문제를 해결하기 위해 소수 게임 (MG: Minority Game) 이론을 기반으로 전송제어 기법을 제안한다. 각 노드는 MG 규칙에 따라 타 노드와의 정보 교환 없이 자신의 이득을 극대화하기 위해 분산적으로 송신 여부를 결정한다. 모의실험을 이용한 정량적 성능 평가를 통해 제안 기법은 DCF의 성능을 송신 충돌 확률 측면에서 향상시킨다는 것을 보였다.

  • 웹 접근성 조치 의무화 시행에 따라 웹 접근성에 대한 관심이 높아지고 있다. 웹 접근성은 장애인뿐만 아니라 비장애인을 포함하며, 사람들은 장애적 상황에 직면하게 되고, 연령이 높아 질수록 신체적 기능 저하로 인해 점진적 장애적 상황이 된다는 점에서 장애적 상황은 누구에게나 해당된다. 접근성은 보편성의 가치를 지향한다. 게임은 현대사회의 대표적 문화활동이 되고 있지만, 한국사회에서 여전히 특별한 소수문화로 인식하는 경향이 많다. 게임을 둘러싼 갈등은 게임에 대한 사회적 이해의 전제적 조건이 되는 접근성 관점에서 볼 필요가 있다. 게임접근성은 보편적 문화적 가치의 구현, 게임 리터러시 전제 조건, 새로운 비즈니스 창출, 콘텐츠접근성의 전망이란 측면에서 사회적 의미를 함축하고 있다.

  • 연간 수없이 많은 온 오프라인 및 모바일 게임이 출시되고 있는 국내 게임시장에서 메카닉 게임의 출시는 아주 극소수에 불과하다. 본 논문에서는 국내 게임시장 중에서 로봇형 메카닉 게임의 시장성은 계속적으로 넓어지지 않고 있는 실정이다. 본 논문은 국내 게임에서의 로봇형 메카닉 게임이 저변 확대가 되지않는 이유와 유독 국내에서만 로봇형 메카닉 게임의 제작 및 수요가 없는 것인가에 대하여 분석한다. 본 논문은 국내 외에 출시된 로봇형 메카닉 게임의 현황 및 판매 인기 순위를 통하여 로봇형 메카닉 게임이 게임사용자들에게 외면되는 이유에 대하여 기획력 부재, 로봇에 대한 문화적 배타감, 조작상의 어려움이라는 3가지 큰 요인을 분석하고 마지막으로 국내 로봇형 메카닉 게임의 활성화 필요성 및 중요성에 대하여 알아보고자 한다.

재앙적 예술과 그 도구화된 선별체계: 헌터 조너킨과 댄 퍼잡스키의 작품으로부터 (Catastrophic Art and Its Instrumentalized Selection System : From work by Hunter Jonakin and Dan Perjovschi)

  • In terms of element and process, art today has already been fully systemized, yet tends to become even more systemized. All phases of creation and exhibition, appreciation and education, promotion and marketing are planned, adjusted, and decided within the order of a globalized, networked system. Each phase is executed, depending on the system of management and control and diverse means corresponding to the system. From the step of education, artists are guided to determine their styles and not be motivated by their desire to become star artists or running counter to mainstream tendency and fashion. In the process of planning an exhibition, the level of artist awareness is considered more significant than work quality. It is impossible to avoid such systems and institutions today. No one can escape or be freed from the influence of such system. This discussion addresses a serious distortion in the selection system as part of the system connotatively called "art museum system," especially to evaluate artistic achievement and aesthetic quality. Called "studio system" or "art star system," the system distinguishes successful minority from failed absolute majority and justifies the results, deciding discriminative compensations. The discussion begins from work by Hunter Jonakin and Dan Perjovschi. The key point of this discussion is not their art worlds but the shared truth referred by the two as the collusive "art market" and "art star system." Through works based on their experiences, the two artists refer to these systems which restrict and confine them. Jonakin's Jeff Koons Must Die! is avideo game conveying a critical comment on authoritative operation of the museum system and star system. In this work, participants, whether viewer or artist, are destined to lose: the game is unwinnable. Players take the role of a person locked in a museum where artist Jeff Koons' retrospective is held. The player can either look around and quietly observe the works, which causes a game-over, or he can blow the classical paintings to pieces and cause the artist Koons to come out and reprimand the player, also resulting in a game-over. Like Jonakin, Dan Perjovschi's some drawings also focuses on the status of the artist shrunken by the system. Most artists are ruined in a process of competition to survive within the museum system. As John Burger properly pointed out, out of the art systems today, public collections (art museums) and private collections have become "something unbearable." The system justifies the selection system of art stars and its frame of reference, disregarding the problem of producing numerable victims in its process. What should be underlined above all else is that the present selection system seriously shrinks art's creative function and its function of generating meaning. In this situation, art might fall to the level of entertainment, accessible to more people and compromising with popularity. This discussion is based on assumption and consciousness on the matter that this situation might cause catastrophic results for not only explicit victims of the system but also winners, or ones defined as winners. The system of art is probably possible only by desire or distortion stemmed from such desire. The system can be flourished only under the economic system of avarice: quantitatively expanding economy, abundant style, resort economy in Venice and Miami, and luxurious shopping malls with up-to-date facilities. The catastrophe here is ongoing, not a sudden emergence, and dynamic, leading the system itself to a devastating end.

  • This study attempts to examine the relationships between the major market-based media and the government after closing military regime era, 1961-1987. After the military regime was collapsed, while the mass media in Korea obtained independence and autonomy from government, they have been confronted with the terrible competition not so much comparatively as before. The watchdog role in the traditional liberalism, which is regarded as normative relationship between the media and the government would be transformed in accordance with the market condition and the maturity of democracy. Thus, the watchdog metaphor has been variously deviated in rower-centered society; lap dog, guard dog, attack dog. liberalists argue that the primary democratic role of the media is to art as a public watchdog overseeing the state. Social democrats, however, criticize them as simplistic conception which could be only applied to the government. They argue that the media should be seen as a source of redress against the abuse of all forms of power over others; the home, the economy, and the civil society. The lap dog view is that the media is overwhelmingly dependent on the established power structure contrary to the watchdog. While the guard dog perspective is a means to preserve the power structure alarming with playing 'conflict role', the attack do8 aims to the private interest of the media in intruding into the politics. The attack dog perspective by T. Patterson could be composed of the interpretive style of report, the game schema report over the policy schema in the election, and the negativism against politics and government. The market-dominant press has been likely to transform from lap-guard dog into attack-guard dog. In Roh Tae Woo government(1988-1992), while the press was a lessened lap-guard dog before three parties merger in 1990, after merger the press had been transformed as the reinforced lap-guard dog because this merger entailed joint, party-to-party negotiations, and the formation of the new party preceded by dissolution of the ruling blot. In the early stage of Kim Young Sam government(1993-1997), the press has kept in pace with the reform movement drive-forced by the government. However, the press withdrew the support of Kim's reform in reaching the level of threat to ruling bloc. The press coalesced only circumstantially with government and was interested in preserving some margin of independence. The failure of Kim's reform proved the political muscle of the press in post-autho-ritarianism. In the middle stage of Kim Dae Jung government (1998-) that resulted in the shift of power structure as once-opposition party leader, the stress has been a manifested attack-guard dog owing to the anti-cold war policy, the realignment policy of power, and the minority-base of Kim's government. The press has endeavored to hold political communication within limits relatively less threatening to the established order.
