A large number of parameters have been defined in order to describe and to evaluate the acoustical propeTies in rooms. Reverberation time is an impoTant characteristic of conceT halls, theaters and studios, etc. Over the years, a number of different methods for measuring the reverberation time have been developed, the most common being: the interrupted noise method, the integrated impulse response method, and the method of recording the room response to an impulsive source. However, the reverberation time can be changed by the measurement method, sound source and microphone. Therefore, it is difficult to accurately measure the reverberation time in a room. In this paper, it will be analyzed the interpretation method of the reverberation time and discussed the limitations.

As multiplex theaters are increasing rapidly in number, concerns over the evacuation process in case of fire emergency are also increasing. The study investigates the users' awareness and recognition of evacuation route by the method of questionnaire, and analyzes the users' behavior in choosing the route by the simulation program called Simulex. Among others, findings indicate a vast majority of the users are unaware of the proper route in the emergency, yet anticipate to evacuate by it, instead of the entry/exit route that they are familiar with. This aspect, however, can be useful to provide the proper route of evacuation for the users, if an appropriate information is given that the entry/exit route is also used as an emergency egress. The simulation shows heavy congestion at the closer evacuation route from the exit, and distinctly less traffic at the farther means of egress. Based on this natural phenomenon, it is suggested that the emergency stair should be nearby and aligned with the exit from auditorium. Although the present building regulation only requires a minimum dimension at each route, there is a need to widen the passageway that is likely to be recognized easily and subsequently overcrowded in case of fire emergency.

This study examines the space composition and character of German Modern Theater barre on the theory of typology and interpreter in the european traditional classic theater. Contemporary multi purpose theater and public space is considered as a symbolic representation of the classic theater's organization. In the historical theory, modern theater was a common tool and best systeme in reflecting people's lives. This role of greece-roman theater as life cycle and new style of theater permanent design has get its value with the population increase and the urban centralization of the city and urban common sense. This study attempts to reevaluate the need of space typology in modern society through a critical review of theater and its use as a open space design. Content analysis was used to discuss the topics of this study including the historical background of the theater, the relationship between amphitheater and modern theater design, and the role of scenery, auditorium and its impact on urban environment. The scope of the study is limited to the comparison of classic theater and german modern theater space use program from the space critic and sociologist. Today the concept of theatrical space is altered with the typology of classic and interpreter space. This study provides insights for the future implications of theatrical space in developing public space for its a new definition as cultural representation.

Video Content owners seek to squeeze the maximum amount of revenue from their assets via distribution into more territories. Digital Cinema Package(DCP), trusted solution to distribute protected content to theaters, caters to relatively small user base, which limits revenue. With the growth of the Internet & other digital media, the economics of media content has changed dramatically. Security remains main concern to deliver content to millions of consumers using intelligent digital display devices like Tablets, Smartphones, Smart TVs, Desktop & Laptop. By making the video content available to this segment securely, content owners will benefit from increased revenue. Through this paper we propose Open Source HomeDCP model to distribute the content to home users for offline viewing. We propose to include other open source CODEC than JPEG2000/MPEG2, which are specifically designed for theatrical performance. Final image size will be further reduced considering the display device resolution where video will be finally played. Key Delivery Message(KDM) system to be altered to suit new devices. This will be a big boost to Content Economy as content owners would be able to distribute the content securely to the wider audience & ensure more revenue.

Recently the number of auditoriums such as theaters, assembly halls, and concert halls is increasing in Korea. Auditoriums have generally large space volume, have a high density of occupancy per unit floor area, compared to other buildings. Since they have relatively high ceilings, some heat may stratify above the occupied zone. The under floor air conditioning system, which is set under seats, is frequently selected in an auditorium, because typical air conditioning system where air is supplied from ceilings often causes drafts and unequal temperature distribution. Therefore, this study aims to suggest basic data for air conditioning system design of a middle-sized auditorium. Features and problems of air conditioning system of an auditorium which has about 500 seats are investigated as a case study. In addition, indoor thermal comfort and cooling energy consumption are analyzed with a CFD program and an energy analysis program.

The stage facilities in the western culture originates in the scientifically planned Open Air Theater built in BC 3C and magnificent theaters built in the era of Rome. These buildings are the remains that reveal popularization of the play. Furthermore, the facilities continued to flourish in the medieval to the Industrial Revolution as stage art actualizing designers' imagination. Diverse systems developed in industrial technology have been transferred to the stage, and the balance between industrial and cultural art has been endeavored to be achieved. The conversion methods of the stage has been developing in various forms. Domestic stage setting arrangement techniques and material exploitation have also been developing. Therefore, in reality, it is very difficult to grasp the definite trend. Additionally, as for the stage system in Korea, plays are dependently directed by directors and stage artists. It is concluded that the current state should be understood based on actual examples to meet solve these problems. The purpose of the study is to provide basic data for stage facilities planning. To do this, how the stage system of large performance halls can be used in accordance with performance condition of the grounds in Korea and frequent scene changes is given a special attention. With this background, the surroundings of the stage and conversion system are examined.
