The purpose of this study is to know about solution of insecurity sense for solving the tediousness and inducing comfortableness in long time MRI examination. Studies were examined with total of 117 patients that the intention expression of self is possible for a month without dividing man and woman in november 2006. Examination methods were filled in questionnaire after testing using Siemens Impact 1.0T. The musical art were selected through intranet search and record sale inquiry using CD player and speaker. That kind of a music were selected with Korean classical music's 10 chapter, pop song 10's chapter, classic's 10 chapter and Korean popular song's 10 chapter. With analytical method, patients of under 40 year-old, or older and patients using ear-pad and head-phone were classified into groups. As analysis result with question item of questionnaire, most of the patients were showed a favor(36.72%) in playing a music, specially, examination of about 15.38% which uses the headphone prefer a music as older generation of over 40 year-old. In conclusion, with installing of the professional musical program in MRI test rooms, if listening to the music with selection by oneself before testing by season, age, time through development of appropriate musical program will be able to expect the more effect.

본 연구는 만성 뇌졸중 환자를 대상으로 시각리듬자극(RVS)을 이용한 보행 운동을 적용하여 보행과 고유수용성감각에 미치는 효과를 알아보고자 하였다. 뇌졸중으로 6개월 이상 장애를 가진 21명이 연구에 참여하였고 실험군 10명과 대조군 11명으로 나누었다. 대조군은 14m의 보행로가 확보된 공간에서 준비운도 5분, 보행운동 20분, 정리운동 5분 씩 주 3회, 4주간 12회을 실시하였고, 실험군은 대조군의 운동프로그램과 같은 조건에서 보행운동시 시각리듬자극(RVS)을 추가적으로 적용하였다. 운동 전과 후에 보행과 고유수용성감각을 측정하여 효과를 비교하였다. 통계처리 방법으로 실험 전 후 차이를 검증하기 위하여 대응표본 t 검정을 실시하였고 대조군과의 차이 검증을 위하여 독립표본 t 검정을 실시하였다. 모든 통계적 유의수준은 0.05로 하였다. 본 연구의 결과 시각리듬자극(RVS)이 적용된 실험군에서 보행속도와 분속수, TUG 시간이 유의하게 증가하였고(p<.05), 고유수용성감각이 유의하게 증가하였다(p<.05). 결론적으로 시각리듬자극(RVS)을 이용한 보행운동이 만성 뇌졸중 환자의 보행과 고유수용성감각에 효과가 있는 것으로 나타났다. 향후 만성 뇌졸중 환자에게 음악적 요소인 시각리듬자극 (RVS)이 정신적 육체적 기능을 상실한 뇌졸중 환자의 재활치료 프로그램에 적용하는 연구가 필요할 것으로 기대되어진다.

This paper proposes a system that can automatically write singing voices to music notes. First, the system uses Stabilized Diffusion Equation(SIDE) to divide the song to a series of syllabic parts based on pitch detection. By the song segmentation, our method can recognize the sound length of each fragment through clustering based on genetic algorithm. Moreover, this study introduces a concept called 'Relative Interval' so as to recognize interval based on pitch of singer. And it also adopted measure extraction algorithm using pause data to implement the higher precision of song transcription. By the experiments using 16 nursery songs, it is shown that the measure recognition rate is 91.5% and DMOS score reaches 3.82. These findings demonstrate effectiveness of system performance.

The purpose of this study was to define the effects of noise and background music on the trunk muscle fatigue during dynamic lifting and lowering tasks. Six healthy male subjects with no prior history of low back disorders participated in this study. The participants were exposed to two levels of background noise such as 40dB noise and 90dB noise and three levels of background music such as no music, slow music, and fast music. Six different combinations of background noise and background music were played while the participants were performing the lifting task at 15% level of Maximum Voluntary Contraction. Electromyography signals from six muscles were collected and fatigue levels were analyzed quantitatively. In results, the 90dB noise increased trunk muscle fatigue and slowed down the recovery. The trunk muscle fatigue was the lowest when the fast music was played for as background. After recovery, the 90dB noise increased trunk muscle fatigue. The trunk muscle fatigue was the lowest when the slow music was played for as background. The results can be useful to manage the cumulative fatigue of trunk muscles due to background noise and music during repetitive lifting and lowering tasks in industry.

Last target of architectural acoustics is that people wish to convey voice effectively from the space adaptively in use purpose in building. But, to how exactly through space sound source that wish to deliver from indoor can be passed does quantification sound estimation method is proposing various kinds physical parameter to estimate degree of voice definition (Speech articulation) and reverberation. Result that evaluate sound source about MLS signal and Impluse signal by pistol in this treatise could know that converge in MLS and measurement error extent about reverberation time(RT) of sound benevolent person. And value is thought there is problem showing change irregularly about sound benevolent person of D50, C80 etc. Finally, in case is spread sound field in difference of sound pressure level, when measure about change of sound pressure level, sound benevolent person could know that there is no different effect.

현재 터치스크린을 활용한 기기와의 인터랙션이 전반적으로 널리 활용되어 스마트시계 또한 출시에 기존의 터치스크린 UI/UX를 그대로 적용하는 경우가 대다수이다. 하지만, 스마트시계의 경우, 필연적으로 기기가 작아질 수 밖에 없고, 그로 인해 장착된 디스플레이도 소형으로 나오는 경우가 많아 터치방식에서 오류 발생률이 높아질 수 밖에 없었다. 이 논문에서는 스마트시계에 탑재된 6축 센서를 활용한 인터페이스 방식을 제시한다. 이 방식은 기존의 터치 방식과 달리 작은 화면을 누를 필요 없이, 시계의 다양한 방향의 모서리 끝을 탭핑(Tapping)하여 신호를 구분하는 방식으로 스마트시계를 조작할 수 있도록 한다. 본 논문에서 제안되는 조작방식은 기존 방식보다 오류발생률을 줄이면서도 간편하게 사용자 이해가능성이 높고, 스마트시계에서의 조작환경(전화 및 문자 알림, 날씨 정보, 음악 재생 및 볼륨 조절 등)을 제어 시 유용하다. 또한, 출시된 스마트시계에도 기본적으로 내장된 센서를 활용한 인터페이스이므로 새로운 센서를 부착할 필요 없이 적용이 가능하며, 스마트 시계뿐만 아니라 스마트 디바이스의 경우, 기본적으로 자이로, 가속도 센서가 탑재되어 있어 타 기기에 대한 적용가능성 또한 높다.

The study is to analyze the success strategies of the Cooperative Integrated Arts Activities in Seoul and to explore ways to implement it to the local public school. According to research, Cooperative Integrated Arts Activities fulfill the purpose of providing universal arts education by being implemented in the school curriculum. They are also characterized by active administrative and financial support and interactive participatory arts education with assured diversity. Therefore, when applying to a local public school, it is necessary to consider factors such as active administrative support, sustainable allocation of human and material resources, customized arts education that engages the all students and reflects their unique characteristics, social distribution through sharing, and continuous monitoring.

The purpose of this paper is to study the development process of our native verses from the Three Kingdoms Period to the Goryeo Dynasty. The contents of the discussion can be summarized as follows. Typical form of "Sanega" from the Three Kingdoms Period to the late Silla/ early Goryeo Dynasty is a well organized 3-layered structure representing the contents of enlightenment of a high priest. Sanaega has a poetic style characterized by distinct literary features compared to other native verses in the same era. The reason is that 10-line Hyangga improves its poetic level as it is aware of Chinese poetry. As it enters the Goryeo Dynasty, this literary composition starts to change. In other words, Sanega declines and quatrain emerges in the front of literary history. Unlike the Three Kingdoms Period ~ the late Silla/ early Goryeo Dynasty, development of quatrain results from that native verses enhances the characteristics of song rather than poem in the Goryeo Dynasty. Native verses form the mutually complementary relationship by adjusting the position as the song rather than competing with it as the poem as Chinese poetry becomes more common. In the Goryeo Dynasty, Sanaega declines and Sijo emerges in literary history, because native verses have been developed in the poetic form to freely express general emotion and to be more loved from the public. It is in the same vein as a native verse in the form of quatrain raises its vitality by enhancing the characteristics of the song through the adjustment of its position compared to Chinese poetry.

Many People are collecting and managing variable information(Image, Graphic, Animation, Text, music files etc.) about personal interests and holding them in common. Most users are using Microsoft Explorer to make a folder and classify many files. but It's difficult to understand the relation of the data instinctively. To resolve this problem, we adopt information visualization method (especially tree-graph control interface). We suggest an interface that all user can drawing a Graph easily and rapidly. So user can see the relations of their data instinctively and control the relation directly with our sketch-based interface.
