The purpose of this study is to provide a reference for stage planning by analyzing current state of major theaters' stage space and understanding feedback from directors belonged to theaters. Each room in total 18 theaters' stage facilities was measured and their usage and requirements were analyzed on the spot. In addition, each director provided their experiential knowledge about appropriate stage composition for musical performance. The findings are as follow: under stage machinery is not needed for musical. Tour teams prefer to use their own show-deck for set conversion. On the other hand, over stage flying system needs to be able to deal with dense, fast, and accurate scene change. The size and location of the motor room needs to be carefully considered. The number of set battens is directly linked up with the size of the motor room, which should be located lower than the gridiron. As stage sets get bigger and complicated, the number of works at the gridiron is also increasing. The grating floor has to have enough strength coping with machines lifting heavy sets. Most sound control for musical performance is being done at F.O.H. these days rather that in the sound control room. It should equip enough work area and related infra especially for tour teams. 1st gallery needs to have enough effective width, power infra for lighting fixture, and strong guardrail. Lastly, the whole process of parking-unloading-transporting equipments and sets from loading dock to stage and vice versa needs to be efficient, and this has to be carefully considered from early stage of planning.

Recently a slat type ceiling is widely used in various spaces, such as music performance spaces and concourse of airport and a general reception area of a building. However, it is hard to find a proper design guideline or material useful in designing such spaces, due to the lack of relevant researches on the effect of a slat ceiling on room acoustics. The present work investigated the effect of a slat type ceiling using a physical scale model method. A 1/20 scale model of a small shoe-box type music performance hall was built and a slat ceiling with different configurations was installed. 6 cases of different ceiling configurations were considered with the combination of 2 slat ceiling height cases and 3 distance cases between slats. The effect of a slat ceiling on the acoustics of a room was evaluated by measuring reverberance($T_{30}$), intelligibility and clarity($D_{50}$ and $C_{80}$), and loudness(G and $G_{80}$).

The research was conducted to investigate the effect of drama education on the empathy and prosocial behavior abilities of middle school students. A total of 45 students participated in this study. Data were obtained through the use of the IRI(Interpersonal Reactivity Index) and the prosocial behavior scales. Those scales were administered to the group of students as a pre-test. Then, drama education was provided for 14 weeks for the group. The same scale was applied again to the group as a post test once the drama education was completed. The t-test on the differences between pre- and post test scores was used to analyze the effects of the program. The results showed that drama education had a statistically significant effect on the empathy and prosocial behavior abilities of students in the group. Finally, this study suggested implications for future performance arts education programs.

최근 다양한 분야(건축, 디자인, 영화관)에서 활용되는 디스플레이 기술들은 대체로 평면에 투영하는 프로젝션 기술을 사용하고 있다. 예외적으로 평면이 아닌 곡면에 투영하는 경우도 있었으나, 기술적인 제약으로 왜곡된 영상을 보정하여 사용하는 경우는 드문 상태이다. 그리고 상호작용의 경우는 기계적 장치에 의존한 초보적 형태가 주류를 이루고 있다. 본 논문에서는 프로젝션 기술 중에서 원통형 곡면상으로의 투영 기법과 모션인식을 반영한 상호작용 기법에 대해서 논하고자 한다. 3D 영상을 곡면에 왜곡 없이 투영하기 위하여, 본 논문에서는 '2-pass 렌더링' 기법을 이용하였다. 이 기법에서는 현재 렌더링 된 영상을 텍스쳐로 저장한 다음 원통형 물체에 매핑시켜 곡면에 적합한 영상으로 보정한다. 그리고 기계적 장치에 의존하지 않는 상호작용을 위해, 카메라를 통하여 실시간으로 사용자 정보(위치, 방향 값)를 입력 받아 원통형 스크린과 매칭되는 좌표 값을 계산한다. 위와 같은 기법들을 구현하기 위한 실험으로 미디어 아트 작품을 제작하였으며, 투영과 상호작용에 관한 알고리즘을 작품에 적용하였다. 이 작품은 하나의 프로젝터를 사용하여 1/4 원통형 곡면으로의 투영과 상호작용을 수행하였다. 본 연구의 결과는 미디어 아트 작품의 프로젝션 모듈로 사용 될 수 있으며, 공연장 건축, 실내디자인, 체감형 인터랙티브 게임, 가상현실 영화관 등 다양한 분야에 적용 될 수 있다.

This Paper Presents a Method for Stitching a Large Number of Images Recorded by a Large Number of Individual Users Through a Cellular Phone Camera at a Venue. In Contrast to 360 Camera Solutions that Use Existing Fixed Rigs, these Conditions must Address New Challenges Such as Time Synchronization, Repeated Transformation Matrix Calculations, and Camera Sensor Mismatch Correction. In this Paper, we Solve this Problem by Updating the Transformation Matrix Using Time Synchronization Method Using Audio, Sensor Mismatch Removal by Color Transfer Method, and Global Operation Stabilization Algorithm. Experimental Results Show that the Proposed Algorithm Shows better Performance in Terms of Computation Speed and Subjective Image Quality than that of Screen Stitching.
