Game and Animation are considered as two different fields. The definition of animation is 'moving picture' and game is a kind of animation which can be controlled by users. Actually, many principles of animation are applied to the production of games, and are even more emphasized in the mobile game contents which are becoming popular these days because of the characteristics of mobile devices such as small screen size. In this paper, we study on the application of the 12 principles of animation through the making of a mobile 3D game called 'Fly to the music' and that game is going to be serviced in late 2006 by SK Telecom. Moreover, we studied the differences between 3d mobile game animation and ordinary animation.

As mobile Web technology becomes more increasingly applicable. the mobile contents market. especially the music downloading for mobile phones, has recorded remarkable growth. In spite of this rapid growth, customers experience high levels of frustration in the process of searching for desired music contents. It affects to a re-purchasing rate of customers and also. music mubile content providers experience a decrease in the benefit. Therefore, in aspects of a customer relationship management (CRM), a new way to increase a benefit by providing a convenient shopping environment to mobile customers is necessary. As an solution for this situation, we propose a new music recommender system to enhance the customers' search efficiency by combining collaborative filtering with mobile web mining and ordinal scale based customer preferences. Some experiments are also performed to verify that our proposed system is more effective than the current recommender systems in the mobile Web.

Recently, demands for leisure and performing arts are increasing. In perspective of enjoying culture away from every day life, interests for music festival are also growing. Music festival industry has been grown rapidly since the mid 2000s and it has become popular culture especially for younger generation. As music festival culture becomes popular, music festival becomes bigger and a number of participants are rising continuously. However, some services which music festivals provide are not interactive. So, it makes difficult users to feel festival experience and to satisfy. Although some festivals are trying to deal with things through mobile applications, those in the market showed weaknesses. Therefore, this study aims to suggest some improvements for music festival application through user research. As the result of user study, improvements and functions of music festival application were deducted.

Today, mobile phone is a necessity of modern life. For that reason, we suggest a particular system of a mobile phone which take a picture of music score image and automatically play it without any technical knowledges about the music score information. This experiment makes midi, acknowleging separate symbols via preprocessing to music score image taken. This paper utilizes 11 sorts of the score image taken by a mobile phone camera for this experiment. Through this method we suggest, as much as 98% on average takes place, which is very high recognizing ratio. Also, as we introduce this system in a mobile phone by porting, it takes 8.63 seconds on average to create midi following input of images.

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.

We have reviewed the potential impact of blockchain technology on the music industry by analyzing the views of academia and the industry experts. The music industry had rapid changes from the physical market to the digital market in the past decades. The consumers download and stream music online and mobile during the digital dominant market. While streaming music has been recently growing at a fast rate, fair distribution of revenue to the artists continues to be an issue. Some industry experts believe that the issue of fair distribution of revenue to the artist may be resolved using blockchain technology, while some are skeptical about the application or the duration of impact. The blockchain may enhance speedier payment using smart contracts, provide additional revenue and promote the music if excellent fan support is achieved. The positive impact on the music industry may only be possible if there are detailed consideration of the industry and careful understanding of the customers.

Top music 10 is a additional service product of the A mobile telephone company. Up to now, A company is just selling it by outbound TM to customers which visit any contents of Top Music 10. In this paper, we proposed a targeting method combining two score models by data mining. The proposed combining model is to find customers more likely to respond to outbound TM. The proposed targeting method is expected to improve both from 32.8% to 44.0% in the response rate and from 54.7% to 61.4% in the retention rate.

As a study on the purchase intention of digital music, the research applied the Extended Model of Goal-directed Behavior(EMGB) with the perceived value and empirically evaluated the impact of variables such as attitude, subjective norms, positive and negative anticipated emotions, perceived behavioral control and desire on the purchase intention. The study was conducted using a survey data collected from valid questionnaires of 342 copies aimed at Chinese mobile music application users and employed the structure equation model. The findings indicate that attitude, negative anticipated emotions, perceived behavioral control towards digital music purchasing and the frequency of past behavior positively influenced users' desire for digital music purchasing. Another result has been confirmed that perceived value, which was an added variable, showed a significant impact on attitude. Along with the frequency of past behavior and desire, perceived value also exerted positive influence on purchase intention.

Differently from instruments which synthesized sounds and tones in the past, voice synthesis engine for music production has reached to the level of creating music as if actual artists were singing. It uses the samples of human voices naturally connected to the different levels of phoneme within the frequency range. Voice synthesis engine is not simply limited to the music production but it is changing cultural paradigm through the second creations of new music type including character music concerts, media productions, albums, and mobile services. Currently, voice synthesis engine technology makes it possible that users input pitch, lyrics, and musical expression parameters through the score editor and they mix and connect voice samples brought from the database to sing. New music types derived from such a development of computer music has sparked a big impact culturally. Accordingly, this paper attempts to examine the specific case studies and the synthesis technologies for users to understand the voice synthesis engine more easily, and it will contribute to their variety of music production.
