The purpose of this study was to investigate whether there were differences in sound quality among telecommunication service providers(SPs). To avoid the influence of brand of SPs and mobile phone manufacturer, a series of structured experiments was planed. Possible source of sound difference were tested such as specific genres of music, contents providers, mp3 players for PC, and mobile phone manufacturers. The results show there are differences of sound quality among telecommunication service providers(SPs). But the difference comes from contents, mobile phone, and MP3 player for PC. The same model of mobile phone from the manufacturer sounded differently depending on telecommunication service providers(SPs). The genre of music did not show consistent difference in sound quality.

Have been so many times to attempt to enhance the usefulness and convenience about using the sample sound of Korean traditional instruments. Was determined additionally VST plug-sequencer and sample libraries, a variety of methodologies, but did not lead to practical use. This study is a work in order to increase the usability of sample sound of Korean instruments. We have developed sound samples of Haegeum and Daegeum based on most widely used Kontakt sampler. Have aimed to develop sound samples for accompanying with useful function supported by Kontakt sampler helping various musical expressions.

In this paper, we proposed the technique to estimate the life cycle of Internet content services based on the logistic regression model. In this paper, to define parameters of Internet contents estimating life cycle by logistic regression model, we used market size, traffic amount, page view and session-visit number as the parameters of Internet contents estimating life cycle by logistic regression model. In this paper, to compare the performance of our proposed scheme, we estimated life cycle for the download services of bell sound & character contents in mobile network. As a result, using our proposed logistic regression, we were able to estimate exactly the life cycle of the download services of bell sound & character contents.

In this study, the relationship of images and sounds of the animations "Dots" and "Loops" which Norman McLaren animated with his Animated sound technique when he worked at Guggenheim museum at New York, are analyzed through the audiovisual analysis theory by Michel Chion, and through the theory of synchronism/asynchronism and parallelism/counterpoint by Siegfried Kracauer. For the results of the analysis, there are a few difference between "Dots" and "Loops" regarding the aspect of sound arrangement and expressive aspect of abstract animation. However, there are being of two main elements of sound, composing with monophony sound, making musical structure with sound effects, and the emphasizing of parallelism with synchronization bewteen images and sounds in common with both "Dots" and "Loops". In "Dots" and "Loops", there are close correlations between pitch of sound and arrangement/shape of image, between loudness of sound and size of image, and between length of sound and length/shape of image. The image and sound of "Dots" and "Loops" have equal relationship each other, rather than subordinate relationship according as image become sound and the sound become new image with the animated sound technique. "Dots" and "Loops" show tendency of minimal art and music video. Since these two films, and remind about the new approach to sound creation in today's animation production.

The purpose of this study is to reassert the important role of sound design in creating narrative space in films. The main focus is on re-interpreting Chion's sound space composition as a narrative structure. The sound design process has been analyzed to find that the physical properties of sound are purposely manipulated to create the layers of sound to be perceived by the audience in the same way as human perception and cognition of the actual reality work, eventually to create the cinematic reality. The hierarchy of the layers is determined by the importance of the narrative information contained in each sound, with the higher layers being appropriate to convey the information of the narrative, and the lower layers being efficient to deliver the emotion to the audience. With this idea, each of the Chion's space composition is explained as a distinctive area in telling a story with the separate narrative role from the others.

Recently, the sound design of the electric vehicle has emerged as one of the new research objects. This study was conducted to explore and examine major values of interior driving sound of the electric vehicle from the perspective of user experience. An exploratory study based on the ground theory extracted contextual information and quietness as independent variables, and then we analyzed the main and interaction effects of those two variables on the usefulness, emotion, and satisfaction through a $2{\times}2$ factorial experimental design. The experimental study demonstrated that the effect on the user experience of electric vehicle can be conditioned by the combination of contextual information sound and quietness. Based on the results of this study, we suggested future research agendas for the optimization of user needs which reflect individual preference of interior driving sound values.

This paper presents a new 3D sound toolkit called $EVE-Sound^{TM}$ that consists of pre-processing tool for environment simplification preserving sound effect and 3D sound API for real-time rendering. It is designed so that it can allow users to interact with complex 3D virtual environments by audio-visual modalities. $EVE-Sound^{TM}$ toolkit would serve two different types of users: high-level programmers who need an easy-to-use sound API for developing realistic 3D audio-visually rendered applications, and the researchers in 3D sound field who need to experiment with or develop new algorithms while not wanting to re-write all the required code from scratch. An interactive virtual environment application is created with the sound engine constructed using $EVE-Sound^{TM}$ toolkit, and it shows the real-time audio-visual rendering performance and the applicability of proposed $EVE-Sound^{TM}$ for building interactive applications with complex 3D environments.

The rapid exchanges of mobile computing environment and development of wireless communication are providing many effects for learning activity of students. Recently, PDA system developers which are studying memory capacity, communication speed and size of screen support techniques to be capable of learning from students in the wireless or moving environment. In this viewpoints, this paper has a purpose to design multimedia learning system to be able to do with sound lecture contents. The implemented system largely consists of two parts which have the teacher module and students module. The one manages learning progress of students, class management, bulletin board and etc. The other is capable of using studying and bulletin functions. The main idea of this research is focus to upgrade the effect of learning without almost treating the existing studies, which can be listening sound lecture and also seeing text and image at the same time.
