이 논문은 하이데거의 사유에서 나타나는 '놀이'개념이 어떠한 본질적 의미를 담고 있는지 해명해 보는 것을 목적으로 삼고 있다. 이 논문에서 우리는 하이데거의 '놀이'개념을 통해, 흔히 주장하듯이 놀이의 의미가 인간의 정신활동과 관련된 유희적인 측면에만 머물러 있지 않음을 보여주고자 한다. 다시 말해 하이데거의 '놀이'사유를 통해, 사회학적, 교육학적, 문화인류학적 의미의 '놀이'와 본질적으로 다른, 이른바 '존재론적 의미'의 '놀이'개념을 보여주고자 한다. 그런데 하이데거의 전체 사유에서 보면, 이 '놀이'개념이 전기사유에서는 주로 '삶의 놀이', '초월의 놀이'로서 등장하며, 후기사유에서는 '놀이-공간', '시간-놀이-공간', '거울-놀이' 혹은 '정적의 놀이' 등으로 등장하고 있다. 따라서 하이데거의 사유에서는 이 '놀이' 개념이 그의 '전회'를 기점으로 하여 전기사유와 후기사유에서 그 의미가 다소 다르게 나타나고 있기 때문에, 이를 구분해서 해명해 보고자 한다.

In this paper based on geometric optics and geometric modeling aspheric surface of the side mirror mold with dead angle reduced have been designed and machined in a CNC machining center, Surface roughness of the mold was evaluat-ed by usin the surface shaping system. Surface generating simulation of a ball endmill process is investigated. Through the simulation based on the surface-shaping system 3-D engineered surfaces and properties of engineered surfaces are obtained, Computer simulation provides the effective working conditions through the prediction of geometric properties of engineered surfaces. The rear view mirror and room mirror play important role on the safe driving condition as a observation of environment but the rear view mirror can not provide complete information of driving environments due to the existence of the dead angle. The analysis on the shape of formed mirror shows that the proposed me？ improves range of a driver's sight.

Aerodynamic characteristics, such as drag and lift, play an important role in automobile design under certain speed conditions. Such characteristics are essential to design an automobile since they are directly related to automobile's performance such as passenger safety and fuel consumption. There is a huge demand for the automobile to have safe performance at high speed. Reduction in drag is also important and it could lead to the solution of air flow induced noise and dust problems. The objective of this research is to find out the aerodynamic differences between conventional side mirror and a modified one using CFD. Although drag generated around a side mirror is only about 7% of the total drag when a car runs, it is very closely related to driver's field of vision and noise generation. CFD simulation of the flowfield around a car side-view mirror was performed using a commercial code; Gambit and FLUENT.

The Yangbanchum was reconstructed based on mask play that had been handed down in Goseong, Gyeongsangnam-do, Korea. Talnori, called Goseong Ogwangdae, is a Korean folk cultural heritage designated as National Important Intangible Cultural Property No. 57. This mask play provides catharsis to the audience by unraveling the hypocrisy and lies of the aristocrats through satire and humor. Our performance team, the ensemble Better Than Medicine (eBTM) used a large fan (Boochae)to create a performance that blew away anxiety and pain. Watching this performance, the performer and the audience feel the consensus of sharing emotions and send strong bonds and support to each other. This study provides that Yangbanchum dance promotes the mental health by feeling emotional sharing through vicarious satisfaction and mirror effect.

This paper focuses on the specificities and semantic meaning of Mikhail Bulgakov's metadrama White Guard and The Flight. The standard conception of metadrama is to purposefully break the dramatic illusion and make bare a playwright's self-consciousness of the theatrical art itself. With the use of the metadrama Bulgakov expressed the essentials of ugly reality, which he couldn't accept as a valuable truth. In this respect, Bulgakov's metadrama becomes at once a window, from which he views the external world in the theatrical vision, and a mirror, in which his political and existential stance as a playwright is reflected. In White Guard Bulgakov described the already theatricalized reality through several instances of 'play-within-play'. In The Flight, composed of eight pieces of dream, a life turned out to be a less solid and less firm reality than dream. Continuously demolishing the cognitive wall between reality and illusion, Bulgakov leads spectators to have a reflective view on the reality. Allowing more powerful demonstrativeness for a play-within-play than for a play-within-play, Bulgakov elevates a metadramatic technique to the level of thematic structure.

In this paper, a direct adaptive control, based on Lyapunov Function Candidate, is applied to a nonlinear Gunner's Primary Stabilized Head Mirror system to derive a parameter adaptation scheme; furthemore, a nonlinear sliding mode control, but also compensating the error in identification of the parameters which are even varying of have uncertain values. The performance of the adaptive controller is determined by the tracking ability to a desired model under some disturbances and the slowly varying parameters of the system. Both adaptive scheme and sliding mode play an important fole in the improvement of the nonlinear system control.

The side mirrors play an important role in driver's safety and convenience. People drive safely based on the side mirrors and room mirror through observation of environment. However, the drivers can not completely confront environments because of the dead angle of the side mirrors. In this research, based on geometric optics and geometric modeling, aspheric surfaces of the side mirror mold with dead angle free has been designed and machined in CNC machining center, Surface roughness of the mold was evaluated by using surface shaping system. The analysis on the shape of formed mirrors shows the mirrors have been reduced the dead angle comparing with the original mold.

The purpose of this study is to investigate the metatheatricality of Harris' plays marked by the device of 'play-within-a-play' - Androcles and the Lion, Arkansaw Bear, and Punch and Judy. In his metatheatrical plays Harris shows that characters perform for themselves and others. The framework that inner performance is going on within the outer frame play is formed on the stage, and this device reminds the audience in the seats that they are representing reality but that they are only in the middle of performing on the stage. Based on this point of view, this study explores fictionality of character, and play. In Androcles and the Lion, the most-performed children's play in America, the metatheatrical elements are shown in the style of commedia dell'arte, which attacks the rigidity of characters' identity in the Roman society. Another well-known children's play, Arkansaw Bear consists of realistic frame play and fantastic inner play in the mind of a girl, both of which function as a mirror each other and help to sustain aesthetic distance to death and reality on the stage. In Punch and Judy, the structure of frame play and inner puppet play reminds that what's going on in the play is just a fictional play and reflects history of children's puppet show. Harris' unique metatheatricality, the heightened awareness of his own artistic medium, offers children educational opportunity to learn about how a play is performed on the stage and contributes to convey mature theme through children's imaginary participation in the process of playmaking on the stage.
