  • This paper proposes the noise robust algorithm to detect the starting point of music. Detection of starting point of music is necessary to solve computational-waste problem and retrieval-comparison problem with inconsistent input data in music content based retrieval system. In particular, such detection is even more necessary in time sequential retrieval method that compares data in the sequential order of time in contents based music retrieval system. Whereas it has the long point that the retrieval is fast since it executes simple comparison in the order of time, time sequential retrieval method has the short point that data starting time to be compared should be the same. However, digitalized music cannot guarantee the equity of starting time by bit rate conversion. Therefore, this paper ensured that recognition rate shall not decrease even while executing high speed retrieval by applying time sequential retrieval method through detection of music starting point in the pre-processing stage of retrieval. Starting point detection used minimum wave model that can detect effective sound, and for strength against noise, the noises existing in mute sound were swapped. The proposed algorithm was confirmed to produce about 38% more excellent performance than the results to which starting point detection was not applied, and was verified for the strength against noise.

  • The analgesic effects of music in people with glasses on perceived pain through cold-pressor task (CPT) is assessed based on three-sequence, three-period, crossover trial with three treatment conditions(music-listening, news-listening, and no-sound) to each subject. Fifty subjects are divided into three sequence groups by randomization, and CPTs under the pre-assigned treatment conditions at each period are performed. Pain responses after each CPT, subjects' pain tolerance (PT) in time scale and pain intensity (PI) and pain unpleasantness (PU) in visual analog scale (VAS) are measured. After classifying the group by whether or not to wear glasses, which is the phenotype of the myopia gene, pain responses are compared by F-tests and Tukey's multiple comparisons. CPT pain responses in group with glasses during the music intervention are significantly different from responses during the news intervention and the control conditions, respectively. This study investigates the pain responses of music intervention in the group wearing glasses, which can be seen as a phenotype of the nearsighted gene, and this result would play a role in explaining the biopsychosocial model of the pain mechanism.

  • 1. Objectives The present study purposed to examine the contents and the principles of music therapy according to Oriental medicine theories in order to prove that music therapy is not a new research area but its principle is found in the long tradition of Oriental medicine. 2. Methods We investigate the possibility of music therapy based on Oriental medicine theories and examine the meanings of music therapy from the viewpoint of Oriental medicine. 3. Conclusions and discussions (1) The principles of music therapy are the principle of homogeneity, catharsis and balance. (2) When one’s mind changes, there are naturally occurred sounds, which are called Oseong (五聲: the oriental five voices exhalation, laughing, singing, wailing and groaning), and the notes defined by arranging the Oseong according to the principle of Ohaeng (五行: the oriental five phases wood, fire, earth, metal, water) are Oheum (五音: the oriental five musical notes Gakeum, Chieum, Gungeum, Sangeum and Wooeum.). If Eum (musical notes) is classified into Ohaeng, it can be divided into Gakeum, Chieum, Gungeum, Sangeum and Wooeum. (3) Change of Sinji (神志: consciousness) induces change of Gigi (氣機: function of Gi), which can change the character of voices. Oseong controls the functions of Ojang (五臟: the oriental five viscera) by ruling one’s Jeongji (情志: emotion). It can reduce the damage of the viscera caused by excessive vent of emotion resulted from unconscious expression of Oseong - Hoseong (呼聲: exhalation), Soseong (笑聲: laughing), Gaseong (歌聲: singing), Gokseong (哭聲: wailing) and Sinseong (呻聲: groaning). (4) Yijeongseungjeong (以情勝情: Control emotion with emotion) therapies, which suppresses an emotion by stimulating another, include Noseungsabeop (怒勝思法: Control anxiety with anger), Heeseungbibeop (喜勝悲法: Control sorrow with joyfulness), (思勝恐法: Control fear with anxiety), Biseungnobeop (悲勝愁法: Control anger with sorrow) and Gongseungheebeop (恐勝喜法: Control joyfulness with fear). (5) Seongeum (聲音: voices and musical notes) can be applied to a stimulation method that not only harmonizes the rhythm of living organs but also controls the occurrence of diseases caused by mutual Pyeonseongpyeonsoi (偏盛偏衰: relative preponderance and weakness) through direct induction of the strength and weakness of Gi function of the oriental five viscera in a human body according to the individual character. Sounds preferred by the patient, the material of an instrument selected by the patient, the character of rhythm and music expressed by the patient and the sound or voice uttered frequently by the patient can be considered in diagnosis and treatments for the patient’s body and mind.

  • Purpose: This research with one group pre-post design was carried out to test the practical feasibility to administrate the Music Movement program developed for the stroke patients. Subjects: 12 stroke survivors at "J" Public Health Center in Seoul. were participated in. The average age was 68 years old, the ratio of sex was almost 5.8:4.2, the duration of was almost over 1 year. Method: Music Movement program was conducted for 2 hours ${\times}$ 1day ${\times}$ 6 weeks. The contents of Music Movement program were consisted of the preparatory activities, main activities and the wrap up activities. The preparatory activities are ice braking, greeting, explanation of the aims of music movement program, and introduction of stroke disease and ROM exercise. The main activities are the body motions with singing and playing musical instruments. The wrap up activities are stretching and joints and discussion of home activities. Data Collection: The outcome variables are muscle strength, finger pinch power, ROMs, flexibility, depression, and life satisfaction. Depression was measured by CES-D(Kim, I. J., 1999), life satisfaction by ladder scale(McDowell & Newell, 1996), and ADL state(Holbrook & Skilbeck, 1983). Data Analysis: SPSS/PC 10.0 for Window was used. Wilcoxon Signed Ranks Test was used to analyze outcome measures. The level of statistical significance was set at p<.05. Results: This program was effective to decrease the depression level of subjects(p<.05). The muscle strength, hand grip power, ROMs, life satisfaction, and rehabilitation state of the subjects were slightly increased but no significant differences were found between the pre and post test. Additionally every patient replied that they were very satisfied and expressed their appreciation for this program very much. Of course they strongly want to continue to participate in and meet the peer group again. Conclusion: Considering these results, the practical feasibility of Music Movement program can be supported. Therefore, this Music Movement program can be examined with the quasi-experimental design with control group and ongoing reviews. After that, this program would be applied in public health centers, medical institutes, and welfare centers for the rehabilitation of stroke patients.

  • This study was aimed to investigate the effects of restaurant in-store color and music congruency on consumer's emotional responses and behavioral intentions. The web survey was conducted among 400 customers(aged from 20~39 years old) who lived in Seoul and Kyunggi, Incheon Province. To find ensemble effect of color and music, 3D studio MAX were used to make high-stimulus(exciting) and low-stimulus(calm) and 3D virtual reality restaurant simulation stimulus were applied. The statistical data analyses were performed using SPSS/WIN 18.0 and reliability analysis, factor analysis, regression analysis were used. Based on the result of the conducting factor analysis, emotional responses were classified into 2 factors: positive emotion and negative emotion. Satisfaction was classified into 1 factor: satisfaction. Loyalty was classified into 1 factor: loyalty. Cronbach's alpha was calculated for the reliability of the survey instrument. Consequently, restaurant in-store color and music congruency were shown to affect positive emotion and negative emotion. Positive emotion and negative emotion were shown to affect satisfaction. Satisfaction were shown to affect loyalty. Music congruency had a higher effect on positive emotion than color congruency. Color congruency had a higher effect on negative emotion than music congruency. The results of this study will serve as a basis of color and music congruency with restaurant atmospherics.

  • This study was examined the effect and the continuity of music therapy for reduce on post-traumatic stress (PTS) in 119 emergency medical technicians (EMTs). The subjects of the study were 42 EMTs in the C area, and the study was conducted from November 25, 2019 to March 1, 2020. The experimental group conducted a total of ten music therapy programs twice a day for five days. The session-specific program was conducted by two music therapists, including the early, mid, late, and closed stages. Each step applied intervention techniques necessary for goals such as improvisation, rhythm making, Nanta, and couple physical activities. The control group was required to take a free break (TV viewing, cell phone games, sleep, exercise, etc.) at the same time as the experimental group's program. The study found that the control group had no difference in PTS before and after the application of music therapy, but the experimental group had a significant decrease in PTS immediately after the application of music therapy and a gradual increase in PTS after 4 and 12 weeks (p<.05). Repetitive music therapy is judged to be an effective way to mitigate the PTS leve for EMTs.

  • It is crucial to a musical artist whether or not they have a musical identity. Major entertainment companies of Korea are strongly promoting a cultural product called 'Idol', where musical identity and musicianship are not important, with careful production and capital. It is important to take note of Prince, who remains to show clearly his philosophy and identity, in the state where lack of musical identity is being promoted. Many studies done on his musical brilliance and uniqueness can be a great incentive to rethink on the nature of music. As an arranger, Prince used tension notes effectively and even showed that avoid notes can be used to express a musical color. Studies on his musical brilliance and uniqueness must continue to be done and become an incentive to not just people who study music but for everyone to rethink the nature of music. There is no correct answer to music, but art has to be the essence of its nature.

  • This study was to investigate the influence of using Therapeutic Instrumental Music Performance (TIMP) in uninvolved hand function for children with spastic cerebral palsy. Participants were recruited from a welfare center for people with cerebral palsy(CP). Ages ranged from 11 to 12, and a total of 15 TIMP sessions were provided for 3 weeks. Hand function tests were used including Jebsen Hand Function Test for hand function, Box and Block Test for dexterity of uninvolved hand, and MIDI (Musical Instrument Digital Interface) evaluation for velocity of fingers. The TIMP program consisted of hand percussion playing and keyboard playing with changes of timbre and tempo. While the scores of Jebsen test and Box and Block test were improved for all participants, outcomes of MIDI analysis showed differences among participants. Overall, hand function improvements were observed after the completion of using the TIMP program, and the results implies that the TIMP program can be applied in upper extremity rehabilitation for children with CP.

  • Accurate classification of input signals is the key prerequisite for variable bit-rate coding, which has been introduced in order to effectively utilize limited communication bandwidth. Especially, recent surge of multimedia services elevate the importance of speech/music classification. Among many speech/music classifier, the ones based on support vector machine (SVM) have a strong selling point, high classification accuracy, but their computational complexity and memory requirement hinder their way into actual implementations. Therefore, techniques that reduce the computational complexity and the memory requirement is inevitable, particularly for embedded systems. We first analyze implementation of an SVM-based classifier on embedded systems in terms of execution time and energy consumption, and then propose two techniques that alleviate the implementation requirements: One is a technique that removes support vectors that have insignificant contribution to the final classification, and the other is to skip processing some of input signals by virtue of strong correlations in speech/music frames. These are post-processing techniques that can work with any other optimization techniques applied during the training phase of SVM. With experiments, we validate the proposed algorithms from the perspectives of classification accuracy, execution time, and energy consumption.
