This study examined the effect of an interactive instrument playing program on the social interaction of adults with autism spectrum disorder (ASD). A single subject design with multiple baselines across participants was applied, and three adults with severe ASD in their late 20s living at a group home participated in this study. Participants received a total of 25 group sessions. During the intervention, participants engaged in structured instrument playing in which initiation and response to socially interactive behaviors were musically cued, and target behaviors were reinforced in the musical environment. At pre- and posttest, the frequency of initiation of and responding to social interaction behaviors were recorded and analyzed. The results of this study showed that the frequency of both initiation of, and response to, social interaction increased for all participants during the intervention phase, compared to the baseline phase. This result demonstrates that interactive instrument playing increased social behaviors of adults with ASD. It also shows that musically delivered social information can facilitate adults with ASD understanding the intention of social partners in social contexts and motivate this population to engage in social interaction.

본 연구에서는 다차원 추천시스템을 기반으로 동영상 음악추천 시 평가 함수R을 극대화하기 위한 각 다차원 구성요소들은 무엇이고, 이들의 상대적 가중치에 대하여 연구하였다. 일반적으로 추천시스템의 구성변수가 많아질수록 평가 함수R을 극대화하는 것이 유리하나, 계산의 복잡성으로 예측성능과 추천유효성을 저해할 수 있어 구성변수의 증가와 추천 성능을 동시에 해결하는 것이 필요하다. 연구대상 음악동영상은 일반 영상과 달리 오디오 정보와 시선 정보를 싱크하여 감정의 흐름을 추론한다. 실험 대상자는 사용자가 선호할 것으로 예상되는 음악동영상을 추론하기 위하여 대학생으로 한정한다.

Recently, we can hear various kinds of music in everywhere and anytime. If a user wants to find the music which was heard before in a street or cafe, but he does not know the title of the music, it is difficult to find it. That is the limitation of previous retrieval system of music data. To overcome these problems, we research a method of content-based retrieval of music data based on the recorded humming, the part of recorded music and the played musical instrument. In this paper, we investigated previous content-based retrieval methods of papers, systems and patents. Based on that, we research a method of content-based retrieval of music data. That is, in case of using the recorded humming and music for query, we extract the frequency information from the recorded humming/music and the stored music data by using FFT. We use a MIDI file in case of query by the played musical instrument. And by using dynamic programming matching, the error caused by the disparity of length between the input source with the stored music data could be reduced.

In this paper, the tone of Daegeum, one of the most representative wind instruments of our country, was analyzed. Daegeum is widely used as Jeongak Daegeum and Sanjo Daegeum, which are played in royal and wind music, and Sanjo Daegeum is mainly played in Sanjo, Sinawi and folk music. The reason why the two pieces of music are being played in different music genres is due to the improvement of the length of the pipe and the location of the finger holes, allowing the Sanjo Daegeum to perform faster than Jeongak Daegeum, apply various techniques, and make the choice of musical instruments harmonized with music by making the difference in tone. For timber analysis of Jeongak Daegeum and Sanjo Daegeum, the composition of the overtones was visually verified through Spectrogram and Spectrum Analizer, in which the results of recordings were recorded by playing octave low, flat, and octave high positions with the same power. From this, Jeongak Daegeum, which is rich in low-pitched sound, harmonizes with solemn music such as royal music, and Sanjo Daegeum, which has a relatively clear high-pitched sound, is well suited to bright music such as solo music.

The aim of this study was to examine the experiences of music therapists in using their voice clinically. The researcher conducted in-depth interviews with seven music therapists who were able to explain their experiences in using voice. Each interview was analyzed using the phenomenological method of Amedeo Giorgi. The data analysis yielded 9 sub-categories and 6 components: "promotion of various feelings due to clinical use of voice", "voice use depending on the therapist's personality", "voice use for therapy", "positive musical experiences with clients in using voice", "difficulty in using voice as a tool for music therapy", and "attempt to change unsatisfactory voice". The result showed that the music therapists had both positive and difficult experiences with their clients in using their voice. Their instances of perceived unsatisfactory voice prompted them to develop themselves personally and professionally. This study is intended to provide a general understanding of voice use by music therapists and offer a solid basis for music therapists to study voice in the future.

As a means to support maternal transition, a home-based music intervention was employed to facilitate mothers' singing to their infants. Four mothers were recruited as volunteers for this study their typically developing infants ranged in age from 2 months to 11 months. Interviews were conducted after the completion of the intervention. An educational music intervention was used to introduce the benefits of mothers' singing to their infants and to encourage four mothers to perform regular singing to their infants for the two-week period. In the interview, mothers provided valuable information regarding their personal experiences, thoughts, abilities to carry out the daily singing, and additional support needs in singing. All mothers demonstrated positive experiences and needs for future intervention development. Overall, the results showed that music-involved educational intervention is beneficial for mothers to support their maternal transition. The need emerged for future studies to develop music-involved educational intervention to support maternal transition.

The purpose of this study was to review the literature on music interventions with older adults and to analyze the rationale for the type of intervention and type of music selected. A search of KCI journals for research including older adults and music-based interventions identified 33 published articles, and 23 of these studies met the criteria for inclusion in this analysis. Included studies were analyzed in terms of the contents of the interventions and the appropriateness of the rationale reported for selecting the intervention and music. Each study was analyzed in terms of the relevance of the reported rationale to target goals and the characteristics of the study participants. The results showed that many of the included studies incorporated a variety of activities but failed to include a valid rationale for using those activities to achieve the target goals. Also, many of the studies tended to select music based on participants' preferences or perceived familiarity without thorough consideration of the therapeutic function of music in the given intervention. This study presents how music therapy interventions with older adults have been conducted without sufficient attention to the selection of the intervention and presented music. There remains a need to delineate which intervention and music characteristics should be utilized to obtain particular outcomes with specific populations.

The purpose of this study was to compare participants' perceived emotion following harmonic changes in music. In this study, 144 participants, aged 19 to 29 years, listened to music online that included low to high harmonic progression in tonal music (major-minor). After listening to each piece of music, participants were asked to rate 4 items using a 7-point Likert scale: emotional potency, arousal, degree to which the harmony impacted the listener's emotions, and listener's preference for the music. There were significant differences between each of the four items upon the level of harmonic progression. When the participants were divided into two groups (i.e., those with a background in music and those with no background in music), there was a significant difference between the groups in terms of emotional potency, but there was no significant interaction effect. This study confirmed that various emotional responses in listeners can be induced by controlling the exogenous variables in musical excerpts. Based on this, it is expected that the harmonic progression level can be provided to the client to be used as an effective therapeutic tool in music therapy intervention.

The stress experienced by employees on international deployment has serious implications for their physical and mental health as well as their work performance. This study aimed to investigate the impact of resource-oriented music listening on work-related stress among employees on international deployment. The study recruited 10 participants of varying ages and occupations who had worked abroad for at least three years and conducted five personalized resource-oriented music listening sessions along with interviews. The Global Assessment of Recent Stress Scale (GARS) and Job Stress Scale (JSS) were used to measure stress levels before and after the intervention. Results showed that participants' work-related stress and perceived stress were significantly reduced following the music therapy intervention. The study also found that "awareness of own's life situation" and "self-acceptance of here and now emotional challenges" were factors that reduced regulatory stress among employees on international deployment. This study highlights the potential of resource-oriented music listening as a useful tool for managing workplace stress and promoting the well-being of expatriate employees.
