많은 사람이 사회적 문제로 인하여 대두되고 있는 스트레스 및 정신질환 문제를 해소하기 위하여 다양한 문화생활을 선택하고 있다. 그중 휴식을 제외하면 취미, 오락, 스포츠가 가장 큰 비중을 가지고 있다. 본 논문에서는 모션 캡처를 활용하여 움직임의 변화를 인식하고 이에 따라 신디사이저 사운드를 발생시키는 시스템을 제작하였다. 해당 시스템은 악기를 대신하여 연주와 춤이 동시에 이루어져 취미와 스포츠가 결합 된 새로운 여가 활동의 가능성을 제기하며, 공연 및 아이들의 교육적 목적으로 활용되는 등 교육적, 신체적, 심리적 건강을 위하여 활용될 수 있다.

국악 샘플링 신디사이저 VST 플러그인 프로그램 보호방법은 국내 최초로 한양대학교 뉴미디어 뮤직 전공에서 개발된 국악기 샘플링 신디사이저의 배포를 위하여 개발되었다. 소프트웨어가 설치된 컴퓨터의 고유인식 번호를 배포자의 서버로 전송, 암호화된 인증키를 최종 사용자에게 다시 부여하는 방식으로, 문화 컨텐츠 진흥원의 지정과제인 "국악연주 가상환경용 입체음향효과 및 국악기 음 합성기술개발"의 사업화에 큰 도움이 되기를 바란다.

Unlike diesel locomotives, electric vehicles have various issues because they have very quiet engine sound. For example, pedestrians are exposed to the dangerous electric vehicles on the road because they can not recognize the electric vehicles' sound. Moreover, the driver is unable to recognize how fast driver's car is driving at a certain speed. To solve these problems, electric cars' sound needs to be artificially implemented and played. This paper examines the problems of the previous sampling engine sound approach. In this paper, instead of using sampling sounds, we developed a novel synthesizer algorithm via programming languages as a software. In experimental results, we demonstrated and verified our proposed synthesizer's approach is superior to the previous sampling approach. In addition, through these synthesizer's approach, we highly expect the proposed synthesizer's approach will give safety, convenience and comfort to the electric vehicles' users.

Unlike internal combustion engines, electric cars have little engine sound and very quiet, causing the following problems to occur. First of all, pedestrians are a threat to safety because they can't feel the car approaching. The driver is also unable to recognize how fast his car is driving at a certain speed. To solve these problems, electric cars should be artificially created and reused. This paper examines the problems of the Sampling engine sound currently being used and uses the engine sound to produce a sound engine sound for the solution. The sampling engine sound has some limitations in making natural engine sounds. To overcome this problem, we studied two methods of using software synthesizers. They found subtractive synthsizing and wavetable synthsizing, which compared wavetabe synthsizing with actual engine, sampling and subtractive methods to find the most similar to real engine sound. We found that data usage and production cost are more advantageous than sampling method and subtractive syndication method.

The present study is purposed to establish a systematic theory for user-friendly approach to the creation of using a programming language using Csound. Csound is a world-wide computer music programming language and a software synthesizer specialized for prominent sound designers developed by Barry Vercoe at the Media Laboratory in M.I.T. The introduction and the main body of this paper suggested as the starting point of creating electronic music and musical sound the time of combination of music with natural sound or sound from specific media from the viewpoint of traditional Western music. and presents a systematic method composed of the principle of the operation of Csound and basic data samples.

In this paper, we implemented polar transmitt converter based on software for next generation digital wireless communication system. The implemented converter converted from rectangular to polar by CORDIC algorithm, and be made up of sweep for DDS output frequency using software control. The implemented converter shows can frequency control up to 1.16GHz within DDS frequency control range by software control. it means that transmitter can be control of varied blocks such as gain, phase, output and etc.. The implemented converter can be applied digital wireless communication system based on SDR.
