This paper proposes a high resolution direction finding method, which is so called the 'averaged MUSIC'. This method uses a new sample array covariance matrix that consists of diagonal components obtained by taking averages of the diagonal component values of the sample covariance matrix for the MUSIC. This paper also shows that the proposed method performs higher resolced direction-of-arrival estimation than the MUSIC in such cases as low signal-to-noise ratio, closed signal sources, and limited number of sensors, based on the statistical analysis.

With increasing interest in the emotional responses to music, research on the regulatory mechanisms of music has been ongoing. This study examines the fidelity of music emotion regulation (MER) studies by analyzing the quality of rationales provided for using music to induce emotional regulation. A total of 45 internationally published studies were collected for review, and analysis was conducted on criteria related to the use of music, including duration, number of pieces, selection rationale, and the selecting agent. Despite the research objectives aiming to investigate the emotional regulation effects of music, it was found that the majority of studies lacked specific information about the music used, and there was weak consistency among the studies. Additionally, reliable evidence for music activities, music selection, and music implementation time was not provided, and there was a lack of logical basis for the regulatory mechanisms of music. The results of this study imply the necessity for fidelity to the rationale of music emotion regulation to establish itself as a research area. Such rigorous fidelity will contribute to increasing the replicability and integrity of research on the therapeutic uniqueness of music.

This study does a qualitative and quantitative analysis of how music by humming is being used by music educators in the classroom. Music by humming is part division of music information retrieval. In order to define what a music information retrieval system is first I need to define what it is. Berger and Lafferty (1999) define information retrieval as "someone doing a query to a retrieval system, a user begins with an information need. This need is an ideal document- perfect fit for the user, but almost certainly not present in the retrieval system's collection of documents. From this ideal document, the user selects a group of identifying terms. In the context of traditional IR, one could view this group of terms as akin to expanded query." Music Information Retrieval has its background in information systems, data mining, intelligent systems, library science, music history and music theory. Three rounds of surveys using question pro where completed. The study found that there were variances in knowledge, training and level of awareness of query by humming, music information retrieval systems. Those variance relationships where based on music specialty, level that they teach, and age of the respondents.

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.

Computing music similarity is an indispensable component in developing music search service. This paper focuses on learning a music similarity function in order to boost cover song identification performance. By using the probabilistic linear discriminant analysis, we construct a latent music space where the distances between cover song pairs reduces while the distances between the non-cover song pairs increases. We derive a music similarity function by testing hypothesis, whether two songs share the same latent variable or not, using the probabilistic models with the assumption that observed music features are generated from the learned latent music space. Experimental results performed on two cover music datasets show that the proposed music similarity improves the cover song identification performance.

The purpose of this study was to analyze and evaluate music intervention research conducted with high-risk neonates in NICUs in both domestic and international settings. Seventeen music intervention studies were identified, and their characteristics, including type of music, music provider, and treatment frequency, and outcomes (i.e., neonatal vital signs) were reviewed and analyzed along with meta-analysis. For music interventions targeting high-risk neonates in NICUs, the effect sizes of the neonates' vital signs were classified as either medium or large. In addition, larger effect sizes were associated with a combination of live and recorded music, nonmusical therapists as the music providers, and treatment frequency of one to five sessions per week. These research findings verify the clinical value of music for high-risk neonates and provide insights into the selection of music elements, music delivery methods, and music providers in NICU music interventions.

These days there are so many music school graduates. There are also many private music education institutions. Therefor the competition in music private education market very tight. In old days people working in education music market had made big money and many parents wanted their girls and boys to learn piano and other musical instruments. However recently birth ratio in Korea has been dramatically dropped and not many parents wants their kids to learn musical instruments because of economic depression and negative music market. Eventually the size of the music education market is decreased dramatically and the competition in music education market is very hot. Therefor without the upgraded management system it is hard to expect over performance in music education market aspects. The purpose of this study was to find out what are the main factors that affect on business performance of the music education institutions. The main areas that researched in this study were success factors, reason of the start-up, and factors of management success. The research was conducted on the owners of the music education institutions. The factors that affect on the outcome of the business performance were diverse. Therefore the management of music education institutions also need the systematical analysis on the location, environmental factors, people nearby areas, differentiated market strategy and other analysis the same as corporate and business management.

The purpose of this study was to explore the use of music for alleviating PTSD symptoms among North Korean resettlers. Out of 80 initial responses from North Korean resettlers living in Seoul metropolitan area, 78 surveys were analyzed. The questionnaire focused on traumatic events encountered, PTSD symptoms experienced, and the use of music in relation to the symptoms. The analysis revealed that all participants had been exposed to traumatic events either directly or indirectly, and 32% of the responders have experienced at least one of the PTSD symptoms in the last one month. Most of the participants perceived music to be necessary in everyday life as well as for managing PTSD related symptoms. On the other hand, only 38% actually use music in everyday life whereas 75% use music for managing PTSD symptoms. They mainly listen to music but also engage in singing, utilize music from both North and South Korea, and they perceive the most important reason for using music to be for emotional comfort and transition. The analysis provides additional information that are valuable for the therapeutic use of music for North Korean resettlers living with PTSD symptoms.

The purpose of this study was to identify current trends in music therapy literature in Korea in order to provide the groundwork for future research. Therefore, 122 articles from the Korean Journal of Music Therapy (KJMT) from 1999 to 2012 and 76 articles from the Journal of Music and Human Behavior (JMHB, formerly known as Korean Journal of Music Therapy Education) from 2004 to 2012 were analyzed. Analysis was performed by identifying the frequency and percentage of the following items: type, population, topic, and methodology of published articles. In addition, the results obtained were compared and contrasted between these two publications. Overall, it was found that there was a high prevalence of descriptive studies (KJMT, 46%,; JMHB, 45%), applied research (KJMT, 51%; JMHB 66%), and quantitative studies (KJMT, 82%; JMHB 37%). In addition, ordinary people with no particular diagnosis were the most often studied population (34%). Differences were found in that a historical study was only found in KJMT whereas a philosophical study was published only in JMHB. Further analysis revealed that JMHB included a higher proportion of applied research than KJMT. In KJMT, quantitative research was appeared twice as often as qualitative and mixed-method research combined. On the other hand, a similar number of each of the three methodological types of studies appeared in JMHB. In conclusion, this study indicates that more effort should be made to increase the quantity and improve the quality of professional publications in the field of music therapy in Korea.

GPS is vulnerable to jamming because of extremely low signal power. Many anti-jamming techniques are studied for complement this vulnerability. Anti-jamming techniques using array antenna are most effective technique and these techniques are required the DOA estimates. MUSIC algorithm and Root-MUSIC Algorithm are typical algorithms used in DOA estimation. Two algorithms have different characteristics, so the choice of an algorithm may depends on many factors such as the environment and the system requirements. The analysis and performance comparison of both algorithms is necessary to choose the best method to apply. This paper summarizes the theory of MUSIC and Root-MUSIC algorithms. And this paper extends both algorithm to estimate two-dimensional angles. The software simulator of both algorithms are implemented to evaluate the performance. Root-MUSIC algorithm has the computational advantage on ULA. MUSIC algorithm is applicable to any antenna array. MUSIC shows better estimation performance when number of array element is small while the computational load of MUSIC is much higher than Root-MUSIC.
