By employing in-depth interviews with a total of 14 television producers, the study seeks to investigate how the use of documentary background music has changed in the rapidly evolving media technology. This study reveals two major findings. First, the use of traditional compositional background music in TV documentary has been decreased for the last 20 years, while library music with various sound sources has been more likely to be used due to its artistic value, its digitalized formats, and its convenience. Second, the popularity of the library music use has changed the cooperative relationship between TV documentary producers and music directors, and their views on background music. Overall, compared to the past, the new media technology (e.g., much easier, faster editing process and communication through e-mails) has helped to come up with the current trend of using more library music. This trend however implies that the dependency of library music only may lose the unique value of television documentary as a work of creative art and eventually downgrade the quality of the programs. Further practical implications are discussed.

본 논문에서는 오디오 데이터를 분석하여 촉각 피드백을 출력할 수 있는 햅틱 라이브러리를 소개한다. 개발한 라이브러리는 안드로이드 플랫폼에서 동작하며, 어플리케이션에서 발생하는 오디오 신호를 이용하여 촉각 효과를 생성하므로, 기존 어플리케이션의 수정 없이 촉각 효과를 제공할 수 있다. 또한 복합적인 오디오 음원으로부터 사용자가 원하는 특정 주파수 대역을 선별하여 촉각 효과를 적용할 수 있다. 마지막으로 개발한 라이브러리를 레이싱 게임 및 음악감상 어플리케이션에 적용한 사례를 소개한다.

In spite of controversial debates on aesthetic issues of computer-generated electronic music, rapid advancement of music technologies in the past decade have resulted proliferation of using virtual software synthesizers and samplers in music composition. Computer-based music production platform has become not only a norm among some of contemporary music composers but also vital apparatus for their compositional process. There are two imperative parts of this compositional process involving sampling in computer-based music production, which are commercially available sample libraries that include pre-recorded audio samples, and music production software that processes them. The purpose of this study is to investigate the process and effectiveness of reconstructive compositional process utilizing distinctive features of sampling on computer music production software. This study addresses issues such as: the definition of audio sampling, how sampling is incorporated in compositional process, and what features of music production software are particularly effective in various musical expressions. The result of this study will hopefully accommodate and fulfill the needs of electronic and acoustic musicians' creativeness.

머신러닝을 활용한 이미지 분류는 단순 사물을 넘어서 사람의 감성과 같은 추상적이고 주관적인 개념에도 적용되고 있다. 이 중에서도 합성곱 신경망을 통한 이미지의 감정 분류 연구가 더욱 활성화되고 있다. 그럼에도 다양한 멀티미디어들을 머신러닝 알고리즘으로 분석하고 이를 의미있는 결과로 재생성하기는 매우 복잡하고 까다롭다. 본 연구에서는 기존 연구를 개선시켜 음악 데이터를 다층퍼셉트론 모델을 통해 분류된 이미지와 결합한 동영상을 파이썬의 다양한 라이브러리를 통해 자동으로 생성하였다. 이를 통해 특정 분위기로 분류된 이미지들과 이에 어울리는 음악을 매칭시켜 유의미한 새로운 멀티미디어를 자동으로 생성할 수 있었다.

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.

Due to a recent advance on the internet access technologies such as ADSL and ISDN, ti becomes possible to watch movies or listen to music at home through the internet. In this paper, we propose Implementation technique and expenence we lcarnet in the development of media plavers operating on Q+ reall-time operating system. The media player can manipulate MPS, MPEG-1, and MPEG-4 streams, and the decofing routime is implemented by software. Ths medial player is operated on the digital TV set-top-box and is implomented by using Q+ librares. In this paper, we focus on programming technique on q+ real-time operating system and performance enhancement technique.
