In contemporary performance arts, we can see diverse types of performances that use advanced technology and visual media. It is notable that animation based on narratives and images, is grafted on to performance arts. Cases emerge that introduce animation in opera performances as part of a new stagecraft. Regietheater that turns on directors' interpretation, has been expanded in full scale through major music festivals and theaters through many different attempts to embody. In this state, recently visual media have been actively employed in opera performances. It has led to expansion of time and space along with more attempts. Not least of all, introduction of animation has been conducive to reinforcing functionality of opera performances in many aspects. This study suggests requirements for ideal Regietheater production in opera performances. For this end, the functions of animation strategically used are evaluated through analyzing $Zauberfl{\ddot{o}}te$)> production of Komische Oper Berlin. Through this research, this study is to look deeply into effects created from new and different attempts by grafting animation on to opera performances.

For content-based audio retrieval which is one of main functions in audio service, the techniques for extracting fingerprints from the audio source, storing and indexing them in a database are widely used. However, if the fingerprints of new audio sources are continually inserted into the database, there is a problem that space efficiency as well as audio retrieval performance are gradually deteriorated. Therefore, there is a need for techniques to support efficient expansion of audio database without periodic reorganization of the database that would increase the system operation cost. In this paper, we design a content-based audio retrieval system that solves this problem by using MapReduce and NoSQL database in a cluster computing environment based on the Shazam's fingerprinting algorithm, and evaluate its performance through a detailed set of experiments using real world audio data.

This paper summarizes the features and functions of game video on each platform through a study on streaming technology. Game videos have a high relationship with game content itself for the purpose of marketing and disseminating game play methods using games as the subject matter. The video length is short and it is easy to spread. The main types of game video content are game commentary, game strategy, funny, imitative, music video, and game information. As a game promotion video function, etc., it is used as a direct or indirect publicity for the game by the producer and the user for each reason. This article analyzed the production subject and production conditions of game videos, focusing on the production process. The production subject is divided into professional creators, non-professional creators, and general users. The motive for producing game videos is mainly to obtain economic benefits. The production process was extracted and presented through examples of game videos.

Feature functions were used for the classification of music. The spectral roll-off, variance, average peak level, and class were chosen to make up a feature function vector. Among these, it is the spectral roll-off function that has a low-frequency to high-frequency ratio. To find the optimal roll-off point, the roll-off points from 0.05 to 0.95 were swept. The classification success rate was monitored as the roll-off point was being changed. The data that were used for the experiments were taken from the sounds made by a modern violin and a baroque one. Their shapes and sounds are similar, but they differ slightly in sound texture. As such, the data obtained from the sounds of these two kinds of violin can be useful in finding an adequate roll-off point. The optimal roll-off point, as determined through the experiment, was 0.85. At this point, the classification success rate was 85%, which was the highest.

The style of performance to contemporary nongak is not fixed in a specific period of time, but in conjunction with the total change in society that has occurred during its long time from traditional society to the modern times. It is important to recognize that the traditional performance art forms that we see and feel today, including nongak, are constantly interacting with the times and are a change in the design that has been shaped in the past. Now, we must get rid of the negative idea that there is some fixed prototype in Nongak. Also, the value and the need for preservation of current Nongak should not be evaluated according to the ' pure genealogy of village descent, ' which was possible only in villages with small population movements long ago. If can get rid of the stereotypes, can greatly expand the view that we read the values of a certain Nongak. Looking away from a few of these traditional fixed perceptions can significantly broaden the view of reading the winning values of some farmers ' songs. In this regard, this report determined the performing style and nature of Changwon's Toichon-noangak through a structural analysis of the Toichon-noangak in contemporary, and discussed the significance of the transmittion of Toichon-noangak. Changwon Toichon Nongak started out as an even-present ritual performance based on the religious nature of the village community and actively exchanged with the economic, social and cultural foundations of the Republic of Korea, which began to accumulate in the modern changes. Generally, the performance style of village Nongak has a combination of characteristics according to the ritual, Dure(collective labor), entertainment, and these three functions. Toichon Nongak is also a village Nongak style and in which of ritual nongak and village entertainment nongak are connected in parallel as one in the big total structure. The origin, background, purpose, and style of towing of Toichon noangak demonstrates that the Toichon noangak is originally ceremonial noangak derived from a prayer style of Dongje. Then, various factors influences are interacting with Toichon noangak within the orbit of modern society, such a style of playing, popular nongak, is believed to have undergone an extended change. Overall, Toichon nongak performance style can be called nongak, which maintains traditional customs and it also has the changed characteristics according to the times of village society.
