In this paper, the theory of superresolution algorithms for estimation of directions of arrival of signals using eigen-structure analysis (mainly MUSIC algorithm)is described. Also, we apply MUSIC algorithm to circularly disposed antenna system, and simulate the angular resolution according to relative azimuth difference, S/N ratio, number of snapshots, so that we confirm the possibility of applications of MUSIC algorithm to sky wave in real situations.

Since their emergence in the 1960s, music festivals have attracted young people the world over with similar tastes, attitudes and styles. Now a worldwide phenomenon, music festivals such as Glastonbury in England, Primavera Sound in Barcelona, Spain and Pentaport Rock Festival in Incheon, South Korea draw hundreds of thousands of attendees from around the world and have become a major event not only for music fans, but for trend forecasters who now chronicle what has come to be known as "festival fashion", which has several distinctive style markers. This paper provides a historical background of festival fashion, examines the phenomenon using fashion theory and discusses the controversies facing the music festival and festival fashion, in particular the role that sponsorship from major corporations currently plays as advertisers who want to get their products into the hands of influential festival attendees and allegations of cultural appropriation on the part of attendees. In conclusion, the future of music festivals and festival fashion as a category is examined.

Discrimination between speech and music is important in many multimedia applications. In this paper, focusing on the spectral change characteristics of speech and music, we propose a new method of speech/music discrimination based on cepstral distance. Instead of using cepstral distance between the frames with fixed interval, the minimum of cepstral distances among neighbor frames is employed to increase discriminability between fast changing music and speech. And, to prevent misclassification of speech segments including short pause into music, short pause segments are excluded from computing cepstral distance. The experimental results show that proposed method yields the error rate reduction of$68\%$, in comparison with the conventional approach using cepstral distance.

Music is now digitally produced and distributed via internet and we face a huge amount of music day by day. A music summarization technology has been studied in order to help people concentrate on the most impressive section of the song andone can skim a song as listening the climax(chorus, refrain) only. Recent studies try to find the climax section using various methods such as finding diagonal line segment or kernel based segmentation. All these methods fail to capture the inherent structure of music due to polyphonic and noisy nature of music. In this paper, after applying moving average filter to time domain of MFCC/chroma feature, we achieved a remarkable result to capture the music structure.

In this paper, we propose that the contrast features of octave spectrum can be used to show spectral contrast features of some music clips. It shows the relative spectral distribution rather than average spectrum. From the experiment, it can be seen the method of spectral contrast features has a good performance in classification of music styles. Another comparative experiment shows that the method of spectral contrast features can better distinguish different music styles than the method of MFCC features that commonly used previously in the classification system of music styles.

This study compared classical operatic singing and applied music singing using the vocal assessment software, Dr. Speech and SPEAD from Lx Speech Studio. Participants in this study included: eight female operatic singers (mean 22.6 yrs, average career 7.5 yrs); eight male operatic singers (mean 25.6 yrs, average career 7.3 yrs); eight female applied music singers (mean 25.1 yrs, average career 6.1 yrs); and eight male applied music singers (mean 27.6 yrs, average career 6.8 yrs). The results demonstrated significantly higher closed quotient values in female applied music singers during singing (p<.05). In addition, higher closed quotient values in speaking were presented in male classical singers and longer MPT was obtained in female operatic singers (p<.05). Furthermore, singer's formants were identified in all male operatic singers and in three female operatic singers. In contrast, only one applied music male and one female singer showed singer's formants while singing.

본 논문은 XML의 여러 응용분야 중에서 악보를 XML로 표현하는 기법에 대한 기존의 연구 현황에 대해 알아보고자 한다. 악보를 XML로 나타내는 방법에는 musicML, scoreML, musicXML, musiXML등이 있다. 이러한 악보를 XML로 나타내는 방법을 응용하여 music XML과 데이터베이스와 연동, musicXML을 이용하여 입력된 악보를 MIDI(Musical Instrument Digital Interface) 파일형식으로 Web상에서 연주하도록 하는 방법에 대해 알아보고자 한다. 이러한 music XML 현황연구를 통해 그 동안의 연구과정에 대해 알아보고, 더 나아갈 방향을 제시하도록 하겠다.

There is a unique method of musical expression in the nature documentary. The expression method is Mickey Mousing technique, which expresses the movement of animals with music. The Mickey mousing technique can also be used in other types of documentaries, but it is most prominently used in nature documentaries. The Mickey Mousing technique cannot be used in any field other than music composition, because the composer should describe the movement of animals by playing music to match the animal's movements exactly. It is also because they have to play the instrument separately according to the sound source. In this study, we examined the nature documentaries broadcast by KBS over the last five years and analyzed the cases of Mickey Mousing technique. Therefore, we obtained research results that the Mickey Mousing technique is necessary and that the music composition is also necessary as a background music of nature documentaries.

The purpose of this study is to examine Ssukdaemeori of Chunhyangga may have effect on depression for music therapy. Ssukdaemeori of Chunhyangga, one of the five surviving stories of pansori (a long epic song), is a touching, sad song in Han Ak (Korean music, 韓樂). In this paper, the author reports on the very sad song, Ssukdaemeori. While listening to the song, Koreans feel the same amount of despair when Ssudaemeori's heroine, Chunhyang, cries out in hopelessness and grief. The author argues that Koreans get to see the saddest parts of themselves reflected back at them in the sorrowful sight of the heroine. It is also believed that Ssukdaemeori has contributed to the healing of Koreans' indignation and pain. For example, depression is currently a social problem. However, listening to sorrowful music like Ssukdaemeori can have a good effect on people feeling sad and depressed.

The jamming countermeasures in GNSS includes anti-jamming technique and jammer localization technique. In both techniques, direction of jamming signal is important and generally the MUSIC algorithm is used to find the direction of jamming signal. The MUSIC is super-resolution algorithm for detecting incident direction of signal. But, the search time of MUSIC algorithm is too long because all candidates of incidence angle are searched. This paper proposes the new method that has less computational burdens and therefore faster than the conventional MUSIC algorithm. The proposed method improves performance speed by reducing unnecessary calculations. In the proposed method, the cost function of conventional MUSIC algorithm is decomposed into the sum of squares and if the partial sum of cost function is larger than the minimum cost function so far, then the candidate is rejected and next candidates are searched. If the computed cost function is less than the minimum cost function so far, the minimum cost function so far is replaced with newly computed value. The performance of the proposed method was compared with the conventional MUSIC algorithm using the simulation. The accuracy of the estimaed direction of jamming signal was same as the conventional MUSIC while the search speed of the proposed method was 1.15 times faster than the conventional MUSIC.
