When a man is called a person crossing borders(PCB), he is a man who pursues communication, coexistence and combination beyond visible and/or invisible borders of nations and disciplinaries. This paper examines Leibniz as a PCB in his life and learning, and how his metaphysics, the pre-established harmony, enabled him to be a PCB.

Modernism is understood as a process of differentiation. Postmodernism or postmodernity, by contrast, involves de-differentiation. There is a breakdown in the distinctiveness of each of spheres of social activities. It is important to explain an examination of the relationships between the de-differentiation and a wide variety of contemporary tourism, expecially postmodern tourism. Also, de-differentiation between the tourism and the social spheres lead to the spatial reflection. Aim of this paper is to examine the processes of de-differentiation between the tourism and the social spheres, which comes out spatially in Jeju island. Especially, location of destinations is concentrated on the coastline in the period of modem tourism. On the contrary, the postmodern tourism shows that the location of destinations are wide spread diffusion its vertically and horizontally. It means that there are to appear a breakdown of distinctiveness between the conventional tourism destinations and the regional person's space.

If a drama play is interested in recreating the play text on stage, the post-drama play aims at a drama that has been liberated from the play text. In this process, the boundaries created by drama theater are dismantled. Actors and audiences, fiction and reality, theater and non-theater, works and events, language and non-language are the names of typical boundaries. The demolition of these boundaries is an opportunity to restore the festival character of ancient Greek theater, which was forgotten by drama theater. This has led to the dismantling of language-centric and play-centricism, which has dominated the play since Aristotle, and has led to a new play. If language-centered, play-centricism has brought about the crisis of drama, the post-dramatic play dismisses them and finds ways to communicate with the audience as new cultural content. The method is found above all in the restoration of dramaturgy. This is because the post-drama plays are more dependent on theatricality than literature. The demilitarized nature of post-dramatic play with enhanced theatricality will be a stepping stone to popularization, and this shows the possibility of post-dramatic play as cultural contents.

This study investigates the characteristic traits of architectural design of Toyo Ito, who has been acclaimed as one of the most famous present-day Japanese architects. Ito' architecture is generally known as media architecture for its specific natures such as lightness, dematerialization, extensive use of shiny glass, etc. In this respect, Ito's architecture is a radical departure from the tradition of the architectural modernism mostly represented by Le Corbusier. In this study, the architectural world of Toyo Ito is divided into four main section: the conversation between architecture and nature, the architecture of the wind, simulation, and virtual reality, Each of these categories is given full investigation together with appropriate architectural model fit into them.

As the sound art field is keep growing and expanding, we shall contemplate from the sociology of the arts and cognitive science point of views to wisely accept and properly appreciate various artistic works and practices. It is because the value evaluation of new arts shall substantially involve analysis and inspections with considerations of today's complex environments, the creative productions, and the consumptions; because, such critiques are necessity for the advancement of new arts. This paper briefly introduces reasoning of including sociological analysis and criticism in evaluating sound arts beyond dichotomy of the fine arts and music fields. It also looks into changes and conditions of cultural arts grants and allowances of the interdisciplinary art genre in South Korea as it has been almost alone a playground for its domestic creative practices of the sound art. This paper is written in a hope to suggest some possible directions for future developments of these contemporary borderless and/or experimental arts.

국가간 경계선이 사라지고 있다. 대신 사회, 경제, 문화 등 영역을 가리지 않고 새로운 질서를 만들고 있다. 세계에 통용되는 하나의 기준이 필요한 시대를 맞으면서 글로벌 스탠더드에 대한 이해와 요구는 시대적 요청이기도 하다. 글로벌 스탠더드는 한마디로 지난 1980년부터 현실화된 탈냉전 과정에서 잉태되었고, 세계무역기구(WTO)의 출범을 계기로 더욱 가속화되어 이제는 개발국가 개혁의 규범으로까지 자리잡고 있다.

The unsteady transitional boundary layer due to rotor-stator interaction was studied at two operation points, the design and one off design points. The off design point leads to lower blade loading and lower Reynolds number. A Navier-Stokes code developed in the previous study was parallelized to expedite computations. A low Reynolds number turbulence model was used to close the momentum equations. All computations show good agreement with experimental data. The wake induced transitional strip on the suction side of the stator is clearly captured at design point operation. There is no noticeable change in shape and phase angle of the wake induced strip even in the laminar sublayer. The wake induced transitional strip at off design point shows more complex structure. The wake induced transitional strip is observed only in the turbulent layer, and becomes obscure in the laminar sublayer and buffer layer. This behavior is probably consequent upon that the transition is governed by both wake induced strip and natural transition mechanism by Tollmien-Schlichting wave.

This article aims to explain the 'people-image' of Bakhtin's works in the light of "Transgredience" and "Transition." According to Bakhtin, the real core of every culture is the people. But he did try to answer the question "what is the people?" I think, the secret of Bakhtinian thought is located in the people-image, because it is the one of the territories that have not been explained. For this purpose, we have to examine four images represented by Bakhtin, - rogue, clown, fool, thief. These images are the concrete and individualized images of people, who can characterize the power of transgredience and transition. They commonly act for changing ordinary borders of identities formulated with nationality, property, status, classes, sex and so forth. In this sense, Bakhtin thinks that the masks are the real nature which can show the mutational power of Being. That is the kernel of Bakhtin's people-image that makes and changes every cultural world. When we accept and practise this perspective positively, we will realize that Bakhtin's position is close to the cultural politics, because a practical power of thought cannot help but being political. That's why we have to investigate Bakhtin's people-image from a vantage point of "Transgredience" and "Transition."

복합화력 발전플랜트의 운전에서 특히 하절기의 첨두부하시에 외기온도의 상승으로 인한 가스터빈의 출력 감소를 해결하기 위한 방법으로 LNG 연료가 보유하고 있는 냉열을 이용하여 압축기로 유입되는 공기 온도를 감소시키는 냉각시스템의 개념을 개발하고자 복합화력 발전플랜트에 대한 설계점 및 외기온도 변화에 대한 탈설계점 모델링 연구를 수행하였다. 대상 프랜트는 940 MW 서인천 복합 발전플랜트 모듈의 단위 블록을 선택하였으며 발전플랜트 전용 해석코드인 GateCycle을 이용하여 가스터빈과 증기사이클의 주요 기기 들에 대한 모델을 개발하였다. 개발된 모델의 결과를 대상플랜트의 시운전결과와 비교하여 모델의 적정성을 검증하였다. 출력, 효율, 온도 및 유량 등 주요 설계인자들이 최대 ~1.3%의 상대오차 범위 안에서 만족할 만한 신뢰도를 갖는 것을 확인하였다. 탈설계점 성능해석은 본 논문과 관련한 연구의 주목적인 LNG 냉열에 의한 유입공기 냉각시스템 설계시의 경계변수인 외기온도 증가에 대한 각 사이클의 특성변화를 대상으로 하였다. 종합적으로 외기온도가 증가하면 압축기로 유입되는 공기의 양과 이에 대응하는 소요 연료량이 동시에 감소하므로 연소에 따른 가스터빈의 팽창비가 감소한다. 이로 인하여 외기온도 증가시에 가스터빈 출력감소율은 0.5%/$^{\circ}C$로서 배기가스를 이용하는 증기사이클의 출력감소율 0.2%/$^{\circ}C$에 비해 민감하므로 가스터빈 유입공기의 냉각시스템의 설계는 복합화력발전 플랜트의 효율 향상에 크게 기여할 것으로 예상된다.
