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.

In general, performing facilities consist of various functional groupings. The functional groupings should be arranged, in relation to each other, depending on the circulation of users in a space. The performing culture in Korea has been rapidly progressed in recent years. However, compared to the superior examples of foreign performing facilities, it still needs improvements and systematic research. In this study, the functional groupings of general performing facilities as well as the circulation patterns of users will be analyzed. From the results of this study, a circulation system for each spatial composition will be suggested for the performing facilities to be constructed in the future.

Recently, the high value added business is steadily growing in the culture and art area. To generated high value from a performance, the satisfaction of audience is necessary. The flow in a critical factor for satisfaction, and it should be induced from audience and measures. To evaluate interest and emotion of audience on contents, producers or investors need a kind of index for the measurement of the flow. But it is neither easy to define the flow quantitatively, nor to collect audience's reaction immediately. The previous studies of the group flow were evaluated by the sum of the average value of each person's reaction. The flow or "good feeling" from each audience was extracted from his face, especially, the change of his (or her) expression and body movement. But it was not easy to handle the large amount of real-time data from each sensor signals. And also it was difficult to set experimental devices, in terms of economic and environmental problems. Because, all participants should have their own personal sensor to check their physical signal. Also each camera should be located in front of their head to catch their looks. Therefore we need more simple system to analyze group flow. This study provides the method for measurement of audiences flow with group synchronization at same time and place. To measure the synchronization, we made real-time processing system using the Differential Image and Group Emotion Analysis (GEA) system. Differential Image was obtained from camera and by the previous frame was subtracted from present frame. So the movement variation on audience's reaction was obtained. And then we developed a program, GEX(Group Emotion Analysis), for flow judgment model. After the measurement of the audience's reaction, the synchronization is divided as Dynamic State Synchronization and Static State Synchronization. The Dynamic State Synchronization accompanies audience's active reaction, while the Static State Synchronization means to movement of audience. The Dynamic State Synchronization can be caused by the audience's surprise action such as scary, creepy or reversal scene. And the Static State Synchronization was triggered by impressed or sad scene. Therefore we showed them several short movies containing various scenes mentioned previously. And these kind of scenes made them sad, clap, and creepy, etc. To check the movement of audience, we defined the critical point, ${\alpha}$and ${\beta}$. Dynamic State Synchronization was meaningful when the movement value was over critical point ${\beta}$, while Static State Synchronization was effective under critical point ${\alpha}$. ${\beta}$ is made by audience' clapping movement of 10 teams in stead of using average number of movement. After checking the reactive movement of audience, the percentage(%) ratio was calculated from the division of "people having reaction" by "total people". Total 37 teams were made in "2012 Seoul DMC Culture Open" and they involved the experiments. First, they followed induction to clap by staff. Second, basic scene for neutralize emotion of audience. Third, flow scene was displayed to audience. Forth, the reversal scene was introduced. And then 24 teams of them were provided with amuse and creepy scenes. And the other 10 teams were exposed with the sad scene. There were clapping and laughing action of audience on the amuse scene with shaking their head or hid with closing eyes. And also the sad or touching scene made them silent. If the results were over about 80%, the group could be judged as the synchronization and the flow were achieved. As a result, the audience showed similar reactions about similar stimulation at same time and place. Once we get an additional normalization and experiment, we can obtain find the flow factor through the synchronization on a much bigger group and this should be useful for planning contents.

This paper is a thesis on media art technology for high-tech performances and exhibitions. After creating an interactive stroke in VR, it is projected in real time through a media facade technique. Among our traditional dramas emphasizing linear movements, movements were extracted from the Bongsan mask dance, and the movements of the lines were used in a media art performance called 'Multi-face Convergence'. When motion data enters the virtual space, geometry consisting of faces is created in the VR space. The created strokes can be set with various brush types, and when performing, a stroke with a red fire effect that matches a dynamic movement was used. It was made to be able to harmonize with the dancers performing the Bongsan mask dance. The medium called VR has characteristics that are not suitable for melting into a performance, but in this performance, it has overcome its limitations by using a technique called media façade. We propose the world's first performance technique that combines interactive strokes with traditional dance performances.

In the early 20th century, Japan built theaters to take possession of colonial culture while establishing the Imperial University, libraries, and museums to accumulate and spread the knowledge of "imperial" Japan. Many different genres made a hit in theaters including theatrical troupes, theatrical companies, and motion pictures. One of the various features of expositions was "spectacles" or unusual events. They were integrated with a national festival in celebration of "5th anniversary of political commencement." In 1915, the longest hit series in Keijo (Seoul) was the dance performance by professional Japanese beauties and entertainers, whose songs delivered the legitimacy of governance. This study focused on the performance in the space of "cultural" spread called theaters, thus examining the "imperial" cultural waves they were in charge of. The study also focused on the tensional relations of Hierarchie along those cultural borders. The performance at the theater Engeikan(演芸館) in 1915 was especially an epoch-making event in the Japanese theatrical community of Keijo (Seoul): first, it marked the emergence of large-scale performance hall called Engeikan(演芸館); secondly, the performance kept its ongoing, stable streak for about 50 days; and it led to the appearance of leading troupes including Geijutuza(芸術座), which put on a show in Keijo (Seoul) in November, 1915. The study examined the issues of theater Engeikan(演芸館) performance in 1915 involving the art company, performance genre, and audience composition, showed that there was the coexistence of entertainment and governance through cultural ruling while securing amusement and entertainment, and found it was accompanied by the organized operation of "Keijo Sponsorship Council（京城協贊會）" which brought together the cultural capabilities of Japanese people living in Joseon. The performance at theater Engeikan(演芸館) in Keijo (Seoul) in 1915 fully reflected the issues involving the tensional relations between different artistic genres, the competing relations between the subjects of performance, and the cultural power.

Most stage directors and designers make use of controling and moving lots of stage set or device as a large automation device or machine to achieve dramatic effect in their performances. Specially, it is very important to use a programmable multi-chain hoist system which is able to move high speed as well as to lift heavy loads. This paper proposes a multi chain hoist servo system to lift or lower a heavy load of about l ton for public performances' stage. It is automatically operated, electrically driven by a control console with a PTP trajectory generation algorithm, a realtime network control algorithm, and 4 step sequential safety algorithm. The efficiency and performance of the developed system are verified through a series of experiments.

What distinguishes Impression Liu Sanjie, directed by Zhang yimou from other stage performances lies in its use of space. Firstly, it breaks the regular way of performing in a limited theater space but instead, impression Liu sanjie bases the stage activities on the real nature scenery. Secondly, it promotes the local culture by combining the unique color effect of the particular nature scenery with its use of the scenery's natural space, with an aesthetic precision. In another word, Impression Liu Sanjie is not a simple performance set on the natural scenery but more of a promotion to the local culture, through the concept of "environment friend" between human and nature, which is brought by mixing the unique color of natural scenery and its natural space. This research analyzes the Impression Liu Sanjie's use of space basing on Proxemics by Edward T Hall. Impression Liu Sanjie adapts its character from a folk tale, employs the form of natural scenery performance, and at the same time to the largest extent throughout its creating process respects the local culture and its natural space. As a result, the performance presents the idea of "environmentally friendly".

'42nd Broadway' is one of the most authentic, genuine and renowned musical pieces among the numerous musicals. By approaching every element in the Backstage from the perspective of an actor who is apart of the show, not a professional photographer, rather than an the usual objects on the Front Stage which is imprinted in the minds of the ordinary people through the media or the numerous flyers sent from the theaters, intented to describe the life as it is in the Back Stage by examining various elements such as the sets or make-up rooms, rather than the momentary, technically staged imageries. In the industrial aspect as well, the implication of this documentary would be that a more realistic set of photography was provided instead of the existing ones that usually focused on the'staged,' or 'guarded' images of the musical as shown in the promotional materials or the Front Stage still cuts.
