This study examined the effects of a tablet PC-based music-making program on the executive function of adolescents with intellectual disabilities. Four adolescents with intellectual disabilities participated in this program. Each participant received 45-minute individual sessions twice a week for a total of 16 sessions. The music-making program was designed in the sequence of planning; learning table PC operations; exploring musical elements; making rhythm, melody, and lyrics; composing loop sections; and presentation of the completed music. The Stroop test, Children's Color Trails Test, and Digit Span and Letter-Number sequencing tests were measured at pretest, midtest, and posttest in order to examine changes in executive function. The participants showed increased scores on all three tests. The participants' attention span also increased and their attempts to correct errors during tasks occurred more frequently at posttest. This study supports the effects of the technology-based program on the executive function of adolescents with intellectual disabilities and presents its expanded applicability for adolescents who show low cognitive function and limited motivation for cognitive engagement.

Standardization of technology for formatting multiple audio tracks and relevant information for interactive music service is in progress owing to the increasing need of consumers for participating in music production to their own taste. In this paper, we introduce the status of MPEG-A Interactive Music Application Format (IM AF) standardization and analyze techniques adopted in the current IM AF.

From a film esthetic point of view, this paper deals with all the sound elements which are speech, noise, and music for the signification of sound in Hitchcock's . The speech makes a mental image auditory through voice-over, and sometimes it has the indiscernibleness of life and death to be incarnate. This paper has demonstrated that the noise also can mark punctuation-narrative boundary besides visual techniques pointed out by Metz, and it cites the sound of falling water which completes shower scene, offsetting a scream in audience's mind. In the music, desire and oppression are symbolized and they are making a dissonance. Upon occasion, the coexistence of two chords represents duplicity in Norman-mother. Also, the music may disappear in the way of silence, being mummified in the time paused. Thus, the common filmic signification of sounds in can be called reconceptualization of the image.

This treatise presents that a possibility of non-musician's composition. In fart, as a development of music composition program(used by IAVA) helps to compose music easily, but non-musician still feels hard to compose some musics and perform some musics even though the band-in-a-box is already existed(which is an auto accompaniment program). This treatise shows non-musicians' special music composition way. Select a cord and put the cord to special program which ratted ‘the cord composition program’, and then the cord composition program creates the rest cords. After this progress, non-musicians overwrite their own melodies in accordance with created cords. Finally, they can perform their own musics with the sound of master-keyboard and other sound sources using by the band-in-a-box program.

디제잉을 하려면 필수적으로, 턴테이블, 믹서, 스피커와 같은 장비들이 필요하다. 하지만 이러한 장비들은 그 크기가 크고 많은 연결선으로 연결되기 때문에 휴대가 용이하지 않아, 일반인들이 가지고 다니면서 디제잉을 즐기고 음악을 믹싱하기에 적합하지 않다. 많은 사람들이 디제잉과 믹싱을 배우고, 또 언제 어디에서나 쉽게 즐길 수 있게 하기 위해서는 보다 작고, 휴대하기 편하면서도 설치의 번거로움이 없는 새로운 인터페이스를 개발할 필요성이 있다. 이 논문에서는 사람들이 언제 어디에서나 쉽게 디제잉과 믹싱을 즐길 수 있도록 해주는 휴대용 무선 믹싱콘솔 장치를 제안한다.

무선기술의 발전으로 인한 이동 중에도 통신을 할 수 있는 이동통신기술의 발전과 더불어 데이터 네트워크 기술이 발달함으로써 언제 어디서나 원하기만 하면 인터넷에 접속할 수 있는 환경을 구축하려는 요구와 노력이 모두 증가하고 있다. 무선인터넷 기술이란 이런 요구에 부응하는 일련의 기술들을 총칭하는 용어로써 이동 중에도 무리없이 인터넷 서비스를 받을 수 있는 환경을 구축한다. `이동 중 Video Conference를 하고 만화를 보며, 게임을 즐기고 인터넷을 하면서 음악을 듣는다.` 이것 모두는 모든 사업자가 앞으로 기본적으로 제공해야할 서비스일 것이다. 이러한 서비스를 가능하게 하기 위하여 고속 무선데이터 전송기술에 대해 더욱 깊이 있게 논의되고 있다.

A main objective of audio equalizer is for user to tailor acoustic frequency response to increase sound comfort and example applications of audio equalizer includes large-scale audio system to portable audio such as mobile MP3 player. Up to now, all the audio equalizer requires manual setting to equalize frequency bands to create suitable sound quality for each genre of music. In this paper, we propose an intelligent audio graphic equalizer system that automatically classifies the music genre using music content analysis and then the music sound is boosted with the given frequency gains according to the classified musical genre when playback. In order to reproduce comfort sound, the musical genre is determined based on two-step hierarchical algorithm - coarse-level and fine-level classification. It can prevent annoying sound reproduction due to the sudden change of the equalizer gains at the beginning of the music playback. Each stage of the music classification experiments shows at least 80% of success with complete genre classification and equalizer operation within 2 sec. Simple S/W graphical user interface of 3-band automatic equalizer is implemented using visual C on personal computer.

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.

The end of the 1990s due to the rapid development of Internet communications and two-way communication advertising, public relations, online music, video, movies, e-Book, and distribution of digital content is actively underway. The combination of Internet and TV, as well as born of IPTV and interactive digital content industry's future has become a key industry. However, these two-way communication that illegal adult sites, illegal Bulletin, illegal Ads, PR, shopping mall, illegal music copying, video replication, such as negative due to the emergence of IPTV and is always around us and should be recognized. For example, on the Internet, which has been operating in the ocean sounds from the music copyright issue, the prosecution decided to prosecute because of the digital cultural content, copyright issues has become an important issue. Status and issues of this paper to learn the digital content, using intelligence to solve these problems, two-way communication advertising, public relations and practice of digital content, practices and courses of students vulnerable to offers for the analysis simulation.
