We propose a unique client-driven music genre classification solution, that can identify the music genre using a deep convolutional neural network operating on the time-domain signal. The proposed method uses the client device (Jetson TX2) computational resources to identify the music genre. We use the industry famous GTZAN genre collection dataset to get reliable benchmarking performance. HTTP live streaming (HLS) client and server sides are designed locally to validate the effectiveness of the proposed method. HTTP persistent broadcast connection is adapted to reduce corresponding responses and network bandwidth. The proposed model can identify the genre of music files with 97% accuracy. Due to simplicity and it can support a wide range of client hardware.

This study focuses on analyzing rhythms revealed in music songs of Korean third-generation idol girl groups. The development of genre and development of rhythm continues and the rhythm of Third World music is strong worldwide. The development of genres and rhythms continues and the rhythms of the Third World music are winning big popularity world wide. In the past, Third World rhythms were used only in countries where rhythm originated and neighboring countries, and the rhythms between countries were combined to occur in various conersence composite forms. In the past, the Third World rhythms were used only in rhythm-oriented countries and neighboring countries, and the rhythms between countries were combined in various and composite forms The changes in the global music market and the structure of the Korean pop music market show the same pattern in the local pop music genre. This study analyzes the phenomenon in which the Dembow rhythm and the tresillo rhythm, one of the rhythms of the Third World music, are concentrated in third-generation idol music, and notes that a certain number of combinations appear in rhythms and melodies. Moreover, this study identifies and compares the origin, the structure and the application cases of the Dembow rhythm and the tresillo rhythm by analyzing 12 songs of Korean third-generation idol girl groups. A game, as a sort of media like a movie, may be subjected to an ambivalent evaluation in accordance with the quality of each content. In this regard, it is necessary to have an active discussion about which game has desirable contents. Emotion which is an influential factor on interaction among players in game design needs to be approached from a social perspective. Also, based on social emotions associated with players, a significant relationship between emotional vocabularies and game emotions should be understood in comparison with social emotions within the game. based on social emotions regarding players As a result, social emotions within the game exhibited differences from the meaning of the terms. It is supposed that this result was caused by the ethical standards and differences in the real world. Accordingly, for qualitative enhancement of games, it is required to utilize the contents of this study, since emotions within the game are based on social emotions regarding players.

It has been passed more than 50 years of the history of music therapy on school aged children since there had been enforced the 'Education for All Handicapped Children Ace' in United states 1975, which had made an important role of music therapist augmented. In the case of South Korea, through reforming the law on March 2005 that therapist educator has to be allocated on the special class in general school, at least, patrol teacher is charged on that, which made possible to start music therapy as initial stage was realized in realistic way on the spot of school. This research has primary concerns as following. The one thing is intended that figuring the opinions of special educators and music therapists involved with the music therapy in elementary school. And the other thing is intended that making a investigation of actual condition on the spot of existing school, moreover, pinpointing at issue and suggesting the change for the better than now. In order to undertake theses intentions, I examined preceding researches and existing data, distributed the questionnaire involved the music therapy of elementary school to the people who are composed of special educators-65 persons and music therapists-30 persons from 18th October to second of November, and analyzed collected by descriptive statistics. According to the analyzed results, it says that special educator and music therapist know well about the necessity of music therapy in elementary school and its effectiveness is manifested in positive way. Moreover, in order to systemize and promote a program of music therapy, what is most urgent thing is the completion of instrument and music therapy room and there are needed strong supports at the level of nation and institution. It has become pervasive on the demand of therapy education by parents in all of the places involved with disabled children such as special school, special class, local welfare community, and early education. This research shows that how therapy and education was connected as music therapy on the spot of the elementary school, and the necessity of the education of music therapy.

In this paper, we present a music retrieval system that compares the geometric structure of a melody specified by a user with those in a music database. The system finds matches between a query melody and melodies in the database by analyzing both structural and contextual features. The retrieval method is based on the geometric hashing algorithm which consists of two steps; the preprocessing step and the recognition step. During the preprocessing step, we divide a melody into several fragments and analyze the pitch and duration of each note of the fragments to find a structural feature. To find a contextual feature, we find a main chord for each fragment. During the recognition step, we divide the query melody specified by a user into several fragments and search through all fragments in the database that are structurally and contextually similar to the melody. A vote is cast for each of the fragments and the music whose total votes are the maximum is the music that contains a matching melody against the query melody. Using our approach, we can find similar melodies in a music database quickly. We can also apply the method to detect plagiarism in music.

ISAR(Inverse Synthetic Aperture Radar) images represent the 2-D(two-dimensional) spatial distribution of RCS (Radar Cross Section) of an object, and they can be applied to the problem of target identification. A traditional approach to ISAR imaging is to use a 2-D IFFT(Inverse Fast Fourier Transform). However, the 2-D IFFT results in low resolution ISAR images especially when the measured frequency bandwidth and angular region are limited. In order to improve the resolution capability of the Fourier transform, various high-resolution spectral estimation approaches have been applied to obtain ISAR images, such as AR(Auto Regressive), MUSIC(Multiple Signal Classification) or Modified MUSIC algorithms. In this study, these high-resolution spectral estimators as well as 2-D IFFT approach are combined with a recently developed ISAR image classification algorithm, and their performances are carefully analyzed and compared in the framework of radar target recognition.

Today, the views on Temporality of space have been changed not only to be based on the concept of time, but also to identify the space with a body adapted to the new circumstances. The study suggests that the actions of performers in space have been important by changes of views and are connected to the music phenomenology mixed with music whose tempo is the phenomenology related with of human consciousness itself, and derives the temporal property by putting them into Rem Koolhaas space with the fluid quality. According to Clifton's Phenomenology of Music, an understanding of music is made in both human body and consciousness as two ways to listen to sounds and enjoy music. Though a correlation between the characteristics of Clifton's Phenomenology of Music and one of resulted from uncertainty and immateriality of modern space Temporality, we could work out four kinds of characters which are the continuity of the fluidity from temporal programs, contrasting changes or synchronicity, the multidimensionality from synesthesia of line and face, ventilation by quality of the material and immaterial circumstances of sound effects, the implication in events resulted from cognition for information and unexpected actions, and the autonomy of the route of a variety of experiences including intimate connection of inter-related events and temporary and diverse external conditions. Hereby Temporality of musical phenomenology in Rem Koolhaas's space can be experienced by systems base oh the importance of host's motion, changes of programs according to the motion as well as uncertainty and immaterial changes. Due to the changes user's emotion and motion is undergone as Temporality that changes automatically.

Recently many treatment strategies have been developed to prevent suicidal ideation as it is increasing. Various community facilities and university centers are carrying out research to develop efficient treatment programs. This study examined how music can be used therapeutically for a case who is going through severe suicidal ideation. Various music therapy techniques are utilized including song psychotherapy, music and imagery and role play instrumental improvisation. A woman with severe depression for seven one-hour session. Both quantitative and qualitative data were collected to examine the changes in the suicidal ideation. As results, there were lots of changes in the client's attitude towards life through exploring inner world. Much of stability and sense of security were gained and emotional hardship was resolved in the process of therapy. The client was able to structure future plans productively as the suicidal ideation was reduced. In the process of role play instrumental improvisation, music allowed her to express issues regarding relationships with others, attitudes and in other areas as well. Music was used "as therapy" and solved many repressed emotions related to the trauma including psychological inhibition, tension, helplessness, lack of energy. Further music was able to bring the "false" ego with "true ego". The study implies that various psychotherapeutic interventions can alleviate depression and reduce suicidal ideation.

This study investigated how music therapists perceive the professionalism of the profession. A total of 98 certified music therapists completed the online survey for a 46.7% response rate, and 78 questionnaires were included in the analysis after excluding incomplete responses. The results of this study demonstrated that music therapists show a high level of standards for music therapy professionalism in general. Meanwhile, the respondents gave their lowest rating on the perception of their occupation as a social service addressing the needs of society. The majority of respondents rated the level of their professionalism as high and they tended to identify individual competency as the most important factor. Also, there were significant differences in perceived professionalism depending on the length of clinical practice and level of education. These results indicate that the quality of training may contribute to a high level of perception on professionalism. Also, lower levels of perception on social aspects of the professionalism support the need for continuing education to broaden the understanding of professionalism. Given the importance of professionalism in enhancing the quality of care for clients and expanding the profession, further studies were suggested to increase understanding of the music therapy professionalism and propose strategies for maintaining the professionalism of music therapists.
