This study investigated numerically the influences of fire curtain and natural smoke vent area on smoke movement in the stage fire of a theater using FDS (Fire Dynamics Simulator). The dimension of the theater stage was 31 m in width, 34 m in depth, and 32 m in height. The area ratios between the natural smoke vent and stage were approximately 10%, 8%, 5%, and 1%. The gap distance between the fire curtain and proscenium wall was 0.5 m. The fire curtain and natural smoke vent area were observed to affect significantly the behavior of smoke movement to the auditorium and the mass flow rates of inflow and outflow through the natural smoke vent and proscenium opening. In addition, under the same natural smoke vent area, the pressure in the stage with a fire curtain was lower than that without a fire curtain.

The purpose of this study is to provide a reference for stage space planning in modern theaters by analyzing and understanding stage components in terms of spatial composition, purposes, and correlation between them, and collecting various opinions from stage managers an directors. The findings are as follow: the determination of the size of proscenium arch is crucial, and it needs to be considered not only with the genre of the performance and the number of seats, but also with the size of the stage facility. The two-dimensional size of proscenium arch affects the scale of stage area in three-dimensional way; the size of main stage comes from the width of the arch, and the length of set battens comes from the stage width, and so on. The height of the arch affects the elevation of gridiron, and the height of the building itself ultimately. The number and length of the set battens are directly linked to the size of the winch room, and so is the number of the winches to the Mcc panel room. The 1st level gallery supplying power to lighting equipment needs to be wide enough for staffs to work with various equipments effectively and safely. Degree of practical usage of under-stage machinery turned out to be very low. In order to cut unnecessary waste and cost, the characteristics of the theater must get set first, and experts who know how stage works need to get involved in planning stage.

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.

This study is to investigate the utilization of Indoor Proscenium Stage Zone Lighting method in the dancing performance. In other words, it is about how we can utilize the principle of zone lighting in dancing performance, a kind of stage art. Stage lights give lights on the stage. Therefore they play big and important roles in dancing performances. Lightings make big influence on the overall atvosphere and situations of the dancing work but most of dancers do not perceive their importance and furthermore they don't know about the lightings very well. To let them know about stage lightings better, we studied lightings form the perspective of the dancers who face the lightings without great knowledge thresh the articles and literature related general lightings and lighting design, books related to stage lightings and dancing lightings, previous studies and academic articles. The most important part of this study is to understand and utilize the principle of zone lightiing. Zone lighting is generally called as cross lighting, which means single light from the crossed two lights. When looking into the principle of the zone lighting of the Indoor Proscenium Stage, it means 45 degree lighting from both sides of the top form the point of the dancer When more than two lights are used, the angle of the light should be $90^{\circ}$or 120. It is the principle of the lighting technology showing the face and body of the dancers ing three dimension. Applying for the principle of this zone lighting to the dancing performance of Indoor Proscenium Stage, the lighting methods and the usage of the lightings were studied. As shown above, the role of the lighting is very important in dancing configuration. We hope that the perception on the dancing lighting will be changed and studies on the dancing lightings. By understanding and applying more principles of lighting, we will make efforts to make better dancing performance and dancing conporsers and dancers shall make more efforts and studies on lighting for better works. Through such efforts, we can have more experts and professionals In dancing lighting field and they will help us to describe and express the intention of the dancing work better as dancing artists. We hope that there will be better quality performances through more and diversified studies in this field.

This study examines the concept and characteristics of immersive theatres through previous studies. Immersive Theatres can be understood as a form of performance that breaks the boundaries between the stage and the auditorium in various spaces so that the audience can actively participate in the performance or immerse themselves sensibly. However, since it absorbs various art forms and continues to change and develop, it is important to recognize the concept by grasping its characteristics as an immersive experience rather than defining it as one. Based on the theoretical background of the concept and characteristics of the theatrical producers and immersive theatres, the producing immersive theatre < The Great Gatsby> is analyzed to derive differences between the immersive theatre and the general performances. In conclusion, it is important to recognize that immersive theatres have audiences at the center of all aesthetic performance environments. The role and position of the audience as a "passive consumer" change to an "active and creative consumer" in immersive theatres where the audience-centered immersive environment and experience are the key, and it was found that not only producers but also the creatives should change their perception of the audience and reflect it in the producing.

In the present experimental study, based on a real-scale theater, a 1/14 reduced-scale model was constructed, and the effects of natural vent and fire curtain in fire of a theater stage were investigated. The case without fire curtain under the opened natural vent showed lower temperatures in the stage, whereas the case with fire curtain under the opened natural vent showed lower temperatures in the auditorium. On the other hand, through analyzing the starting time of the temperature rise at the point near the proscenium opening in the auditorium, it was found that the opened natural vent condition can delay the starting time of smoke spread from the stage to the auditorium and suppress the temperature rise in the auditorium. Under the present experimental conditions, the fire curtain installation did not affect significantly the velocity and mass flow rate of the outflow through the natural vent of the stage, which might be due to openings in the stage. The present results can be used to examine the effects of natural vent and fire curtain in a real-scale fire of a theater and to check the accuracy of the numerical simulation code.

Although a fire curtain plays an important role in preventing smoke from spreading to the auditorium in a theater fire, there has been insufficient research on fire curtains. In this study, to check the accuracy of numerical simulation, for previous experiments using a reduced scale model, a numerical simulation was carried out, and the results were compared with previous experimental data. The fire curtain effect was then predicted numerically. A Fire Dynamics Simulator (FDS) was used, and the natural exhaust vent sizes were set to ~10%, ~5%, and ~1% of the stage floor area. The smoke movement was visualized, and the mass flow rates and temperatures were measured and analyzed. In addition, the law of similarity was used to examine the influence of a fire curtain in a real scale theater fire. Without the fire curtain, the present numerical simulation results were in agreement with the previous experimental data within reasonable accuracy. Meanwhile, the fire curtain affects the mass flow rates through the natural exhaust vent and proscenium opening, as well as the start time of soot outflow to the auditorium. Overall, the present results can be used to develop a fire curtain system.
