Geugyesuryeonguhoe founded the Silheommudae and chose Nikolai Vasilevich Gogol's Revizor as the founding performance. This Revizor theater performance was a performance equivalent to the founding performance of the Geugyesuryeonguhoe, so it had to be based on the discussion and consensus of the members. Nevertheless, the reasons for selecting this work, the actual performance situation, and whether or not it was successful were not properly addressed in the research data so far. As a result, Revizor performance of Silheommudae did not escape the powerful influence of Revizor theater performance performed at Tsukiji(築地) theater in Japan. In addition, the original design of stage, acting and acting concept of Silheommudae was not confirmed. After this performance, the change of the performance method of Geugyesuryeonguhoe was inevitable. And Geugyesuryeonguhoe was forced to carry out its own reflection on the problems in the stage process.

The purpose of this study is to derive the preference factors of stage acoustics for duet performers through the measurement of the stage acoustics in a concert hall and the performance evaluation on the stage. 15 pairs (total 30 players) of the performers participated in the experiment, and the preference of selected 5 locations were evaluated. As a result, the preference in the center of stage was the highest, and CS (Clarity at stage) and $ST_{Late}$ were the most significant factors for the preference.

In this Paper, the effect of stage ceiling height on the acoustic characteristics of rectangular concert halls are investigated. To find out the acoustic properties of audience area, A simple Boston Symphony Hall(BSH) model which is typically rectangular shaped was applied for computer simulation. A newly built rectangular concert hall with 400 seats was also chosen for a scale model $(1.2m{\times}0.68m{\times}0.31m)$ study and its computer simulation varing the stage ceiling height and the volume. The results show that RT increased as the stage ceiling was lowered and the difference rate of RT by its variance is from -0.09 to -0.06[sec/m].

In this paper, we presented a design and control method of multi-stage with wagon and lift stage. Multi-stage system has 4 degree-of-freedom(DOF), i.e., forward/backward/left/right/rotate and up/down motion. Wagon mechanism in the type of two wheel and steering is proposed in order to improve for the maneuverability compared to the existing differential-type wagons. Also, the lift mechanism is designed by interlocking type in order to make the maximum height bigger than 10 times of the original height. We also proposed a path planning algorithm. The performance of the propped system is validated via multi motion experiments, so that the multi-stage system is useful for various performances production.

This study investigated that the preference model of soloist performers for both vocal and instrumental types in terms of a stage support parameter, ST1. The test was carried out on a stage of a fan-shaped multi-purpose hall with orchestra shell. Objective measurements were carried out at 15 positions on the stage to evaluate various stage condition. The results showed that ST1 varies between -19.9 and -11.3 dB. Vocal and instrumental players participated in performance evaluation test as they played at 5 selected positions according to ST1 values. Players' preference was evaluated by 5-point rating and rank ordering method. As a result, it was found that the preference model of vocalist is different from that of instrumentalist. It was also found that the ST1 does not correlate well with the performer's preference.

본 연구는 실감미디어를 활용한 무대기술 적용을 위해 UWB 센서를 이용한 동적 피사체 추적 시스템을 제안하고자 한다. 최근 공연산업에서는 실감미디어를 활용하여 관객의 오감을 자극하여 극도의 몰입감을 제공하는 시도가 지속해서 증가하고 있다. 특히 배우와 무대장치의 움직임을 실시간으로 반영하여 디지털 미디어 연출 요소로 활용한다면 관객의 실재감과 몰입감을 효과적으로 증대시킬 수 있다. 하지만 대부분 위치추적 솔루션은 제조, 물류, 유비쿼터스 자동화 시스템으로 연구가 활발히 진행되고 있으며, 공연 무대기술과 관련하여 위치추적 솔루션 연구는 미진한 실정이다. 따라서 본 논문에서는 고속의 근거리 무선 통신망을 제공할 수 있는 해결책으로 최근 주목받고 있는 Ultra Wide Band 무선 센서를 사용하여 무대 공연기술 활용에 적합한 동적 피사체 위치추적 시스템을 개발하고, 그 성능을 실험하여 위치정보의 정확도를 분석하고자 한다.

Live cinema theatre is the latest installment of multimedia show where the filming of the performance of dramatic texts becomes the live stage event. Here, the actors perform before the camera and all the audio-visual effects are produced and constructed live. Mediated through the camera and projection screen, the stage image becomes a real-time production situation where all the scenes are put together right in front of a live audience. The very concept of live cinema as dramatic theatre has been developed by English stage director Katie Mitchell who attempts to present the stage as a cohesive representation system; this is more than a provisional experimentation where the ever-changing notion of in-betweenness is constantly tested. It is rather a predetermined operational system where the relationship between cinema and theatre is governed by the logic of synchrony, therefore maintain their own individual institutional reality. Here, the presence of camera has an effect not only on the organization of stage but also an affect on how human body exists within the situation.

An exact curved path has to be fixed and velocity profile for travelling on the curved path is required by a moving stage. In this study, we decide the curved path on the basis of the information on three point locations. The path of the moving stage is traced by simulating the designed curve path and the velocity profile, and the results are compared with the given three points to determine how closely the moving stage follows the given path. Further, we propose a method to calibrate a curved path and velocity profile. The proposed moving paths were evaluated by performing experiments. Finally, the designed curved path and the actual path were compared.

In this paper, we present a software for placing instruments on stage based on the acoustic properties of the concert hall. In order to simulate the changes in sound depending on the positions of the instruments, we incorporated the idea of location-based reverberation effect which can be realized through the convolution of instrument sounds with the impulse responses from the respective instrument positions. And we developed a software with a real-time convolution engine which enables the user to conveniently simulate the resulting sound of various instrument placements. The software was tested with the impulse response data measured at two concert halls of the National Center for Korean Traditional Performing Arts and Korean traditional instrument sounds. Results of these experiments show that simulated reverberation effects properly represent the spatial placement of instruments on stage.

In the present study, the influences of the fire curtain and natural vent in a theater fire were investigated through the numerical simulation of a reduced-scale model of a theater fire using the Fire Dynamics Simulator (FDS). Based on a previous experimental study using the reduced-scale model, the 1/14 reduced-scale model and its conditions were constructed according to the law of similarity with a real-scale theater. Through a series of numerical simulations, the smoke movements were visualized, and the temperatures in the stage and auditorium, mass flow rate of the outflow through natural vent, and time at which smoke started moving toward the auditorium were measured and analyzed. The general trends on the effects of the fire curtain and natural vent during the theater fire predicted by the present numerical simulation were similar to the previous experimental results. For quantitative comparison of the present numerical simulation and previous experimental results, the mean percentage errors of temperatures in the stage and auditorium, and the mass flow rate of outflow through the natural vent were calculated. The present numerical simulation results showed good agreement with previous experimental results with reasonable accuracy.
