This paper proposes an effective feature compensation method to improve speech recognition performance in time-varying background noise condition. The proposed method employs principal component analysis to improve the variational model composition method. The proposed method is employed to generate multiple environmental models for the PCGMM-based feature compensation scheme. Experimental results prove that the proposed scheme is more effective at improving speech recognition accuracy in various SNR conditions of background music, compared to the conventional front-end methods. It shows 12.14% of average relative improvement in WER compared to the previous variational model composition method.

Music with the development of the media since the 20th century marks a change into an era where the live performance and music of the masses, which were hard to imagine in previous times, are shared. Based on this cultural trend, teenage music, which has been completely alienated from existing culture, is in line with the birth of Rock 'n' Roll, an event that has entered the mainstream, and the emergence of the guitar, especially the solid body electric guitar. The Fender Stratocaster, which is referred to as the epitome of this electric guitar, has joined the history of popular music for rock 'n' roll. To this day, the immense influence, which still encompasses many followers and generations, has served as a bridge that continues to be reproduced, even in the historical trend of popular music and the status of electric guitars. In addition, even in the rapid development of popular music and media, we will always be able to give true meaning and value to the vitality with the times. This paper examines the features and marks of these Fender Stratocasters.

The purpose of this study was to analyze data regarding the effects of group music therapy with adolescents. 27 master's, doctorial theses and published articles between 2000 and 2012 were selected for meta analysis. Subjects, independent variables, dependent variables, and the number of session were used to compare the effectiveness of group music therapy program. 49 effect sizes using means and standard deviation from 27 studies were calculated. The results were as follows. The overall mean effect size was -0.14, which is small size effect, according to Cohen's ES interpretation criteria. The mean ES was influenced by the subjects(adolescents/maladjustment students/addictive students/students in facility), the ES of adolescents was the biggest. However there were no significant difference among subjects. During the independent variables(active music therapy/receptive music therapy/combined music therapy), combined music therapy showed the biggest efficacy. When results were sorted by the dependent variables (social/emotional/behavior/cognitive category), the ES of behavioral category was the biggest. However, there was no significant difference among them. The ES of 11~15 session was the most effective.

This study is to explore the effect of music characteristics (i.e., likeliness and familiarity of music) on the relationship between mood and attitude toward the product in the online shopping mall selling hand-made shoes. A total of 319 consumers participated in experiments with online shopping mall stimuli with a variety of background music. In results, consumer mood positively affected attitude toward the hand-made shoe products in the online shopping mall under background music. A moderating effect of music likeliness was found in the relationship between mood and product attitude, indicating that mood more strongly affected product attitude under more liked music than under less liked music. When consumers are listening to more liked music and are in good mood, they may build their attitudes toward products independently from their mood, whereas they may build positive attitude under good mood versus negative attitudes under bad mood if they are listening to less liked music. A moderating effect of music familiarity was not found in the relationship between mood and product attitude. Based on results, it was confirmed that the S-O-R model could be applied to explain the effect of background music on consumer responses in online shopping malls. Marketers may be able to select and adjust the likeliness and familiarity of background music to better serve consumers in diverse shopping conditions, referring to the study findings.

Claude Debussy's is a solo piano piece written in 1894. However, for unknown reasons, the entire piece was not published until 1977, despite clear evidence that Debussy intended to publish it during his lifetime. Interestingly, the second movement of the three pieces comprised in the work was published independently in February 1896 through the Parisian periodical Le Grand Journal. Partly because the work was recently published, it remains relatively more unknown to pianists and music lovers than other piano solo pieces by Debussy. Thus, this article addresses in detail the compositional background of this work, focusing on why the work was not published during Debussy's lifetime. Furthermore, by analyzing this piece in detail, this article intends to discuss the stylistic characteristics of the work regarding its melody, phrase structure, harmony, and form. This survey, which would help understand the musical style embodied in this piece, aims to contribute to improving the awareness of the work.

Plagiarism concerns in the melody of popular music are on the rise. Despite these concerns, standards and methods for addressing these issues are lacking. This study is significant in the fact that it is the first case in the media which started as a controversy on plagiarism of popular music and even progressed to Supreme Court ruling. The first and second trial courts declared the existence of infringement of copyright by recognizing that the music in question was substantially alike as a result of comparing and reviewing the melody, rhythm, and harmony. However, the Supreme Court came to a different verdict on the infringement of musical work by reversing and remanding the case to the Seoul High Court. The Supreme Court indicated that even though the music presented in the first trial is a creative work entirely protected under the Copyright Act, expression without creativity is an area that is not protected under the law. Based on this case, this study seeks to compare and analyze the essential characteristics of melody in the judgment of infringement of copyrights in popular music, and factors related to the judgment of practical similarity and the judgment of idioms that are the criteria for judging infringement of musical work.

In this paper, We propose real-time sound editing and playback systems which is based on Augmented Reality. The proposed system are composed with music maker which is based on AR maker and music board. By using music marker's contents, the proposed system selects the kinds of musical instruments and pre-defined midi track and by calculating the relative location of music marker on 2-dimensional plane, we set the spatial relative parameter in midi track. For performance evaluation, we check the jitter value of in various resolutions by using CAM which supports $1600{\pm}1200$ as the maximum resolution. As a result, when we set the configuration value of CAM as $860{\pm}600$ pixels and process two frames per minute, the success ratio of recognizing music markers and jitter values are accegnable. It can be utilized in the fields of alternative cmacine which is based on music and also be utilized in the educational aspects because child or elderly who don't know enough musical theory can easily handle it.

The purpose of this study was to analyze the rationale and format of music therapy interventions with patients receiving hospice or palliative care in Korea. Through this analysis, I examined whether the music intervention used was based on a valid rationale and represented the professionalism expected of today's music therapy interventions. A total of 12 studies that met the selection criteria were identified, and the overall characteristics of each study and its format were analyzed. As a result of the analysis, it was confirmed that the rationale for each study and its format were influenced by the author's research field. The analysis also showed that the research on music-based interventions in hospice or palliative care settings was insufficient and involved a mix of professional and nonprofessional interventions. The results of this study suggest that importance of researchers possessing professional competence which requires offering a clear justification for their choice of interventions, music, and instruments. Additionally, these results emphasize the need for further development of evidence-based music therapy approaches in hospice and palliative care settings as the role of music in supporting patients in these environments has gained increasing recognition and validation.

팝음악이 국내에 들어오면서 우리와는 체격조건이 다른 그들의 노래를 부르기 위해 가수들은 부단히애를 써야 했으며, 많은 시행착오를 겪었다. 때론 무리한 발성으로 인해 성대가 손상되는 경우도 비일비재 하였다. 가수 조용필은 자신의 신체적인 한계를 극복하여 가창력을 최대화 시킬 수 있는 해법을 우리의 국악에서 찾았다. 그 대표적인곡이 바로 "창밖의 여자"인데 이 노래는 조용필의 최고의 히트곡이자 가요발성에 있어 새로운 전환점을 만들어준 곡이다. 본 연구에서는 당시의 시대적, 음악적인 배경 등을 통해 가요계의 전반적인 상황이 어떠했는지를 파악하여 왜 그 노래가 당시엔 획기적인 창법이었는지 그 이유를 제시해 보고자 한다. 또한 "창밖의 여자"의 곡의 흐름과 감정처리 방법, 테크닉 등을 분석해 봄으로써 호흡과 발성이 어떻게 이루어지고 표현되었는지를 연구해 보도록 하겠다.
