The positive effect of percussion instruments can induce increases in self-esteem and decreases in depression in the elderly. Based on this, the content for a percussion instrument robot that the elderly can use to play music is developed. The elements of the interaction between the elderly and the robot through the robot content are extracted. Music that arouses positive memories in the elderly is selected as part of the music therapy robot content in order to relieve depression, and a scoring system for playing music is constructed. In addition, the interaction components of the robot's facial expressions, which stimulate emotions and sensitivity in the elderly, are also designed. These components enable the elderly to take an active part in using the instrument to change the robot's facial expressions, which have three degrees of emotion: neutral-happy, happy, and very happy. The robot is not only a music game machine: it also maximizes the relief of depression in the elderly through interactions with the robot that allow the elderly person to listen to what the robot plays and through the elderly person becoming involved and playing music along with the robot.

This paper is to propose for the production of a digital-based new interface for the percussion of samulnori which are drum, janggu, jing and kkwaenggwari. Newly designed interface is similar to a jing-shaped percussion, and it was designed to playall of four instruments from a single interface. Two batting sufaces, which are located both in front and at trunk of the interface, generate a hitting date creating when interface to be hit and a pressure data when to grip the handle by control unit located at the handle. The information generated is transmitted to a computer via a wireless communication, and then, the computer generate a synthesized sound based on the characteristic of each instrument.

The Jing is a traditional Korean percussion instrument which plays a major role in Korean folk music. The distingishing feature of this instrument is its unique, long lasting low tone timbre. In this paper, we investigated the vibro-acoustic characteristics of the Jing. Our attention was focused mainly on findings out the physical variables that determine its unique sound. By understanding the way in which the Jing is manufactured, we were able to realize that the unique manufacturing and especially the tuning process by expert craftsman is responsible for the peculiar timbre the Jing produces. The experimental methods implemented to analyzer the Jing were planar acoustic holography and direct measurements by accelerometers. The results from the holographic method and the direct measurements were in good agreement. It turned out that unlike most percussion instruments which have inharmonic partials, the Jing has harmonic partials which are responsible for its unique low-tone timbre. From the holographic representations of the modes, it is clear that the antinodes are located in the center of the Jing which is coincident with the typical striking location. In addition, intensity maps were constructed so that the specific acoustic energy flow can be visualized. It was also interesting to see the the circulation of energy intensity which corresponds to the rotating mode of the Jing.

PURPOSE: This study examined the effects on the upper extremity function, muscle strength, and hand function of a task-oriented training approach using a percussion instrument for patients with chronic stroke. METHODS: Twenty-four chronic stroke patients accompanied with upper extremity hemiplegia were selected for research and were classified randomly into 12 experimental groups and 12 control groups. The experimental group performed a task-oriented approach, and the control group performed upper extremity occupational therapy. Stroke upper extremity test, Jebsen-Taylor Hand Function test, upper extremity muscle strength test, and hand muscle strength test were measured before and after training in the evaluation process. RESULTS: In the upper extremity test and Jebsen-Taylor test, there were no significant differences between the groups. In the upper extremity muscle strength test, there were significant differences in shoulder flexion, internal rotation, and elbow flexion in the experimental group. In the hand muscle strength test, there were significant differences in the grip, tip Pinch, lateral Pinch, and 3-jaw chuck in the experimental group and significant differences in only grip, tip pinch, and lateral pinch in the control group. In addition, there were significant differences in the lateral pinch compared to the amount of change. CONCLUSION: Task-oriented approach using percussion instruments for upper extremity rehabilitation in stroke patients is effective in the upper extremity function and strength, hand function, and strength.

This study investigated the performance patterns in percussion improvisation of adolescents with behavior problems. A total of 40 middle school students participated in this study. Based on prescreening test results, the participants were assigned to either the impulsive tendency or depressive tendency groups. Both groups received two 45-minute group percussion improvisation. During the improvisation, all playing behaviors were recorded and analyzed in terms of rhythm pattern, instrument selection, intensity, and tempo of performance and performance duration. The results showed that while they were differences in improvised rhythm patterns between the two groups, the groups showed a similar tendencies in their instrument selection. With regard to performance parameters, the two groups showed significant difference in the tempo and duration of performance, but no significant difference was found in terms of intensity. This indicates that adolescents who exhibit behavior problems may be different in their playing patterns depending on their behavioral tendencies. Based on the results, music therapists can have a better understanding of how musical features expressed by this population relate to their inherent emotional and behavioral traits and how therapists should facilitate musical expression of these adolescents to address their needs.

The aim of this article is to suggest that Samulnori will be able to produce better and more lovable language. Samulnori is a good example of the Korean music. Samulnori is originally meaning four-percussion play. Janggu and buk made of leather which were mainly cowskin and dogskin. But jing and kkaengwari made out of brass. Four percussions are an instrument composed of a pattern based on the theory of yin and yang. The principle of Samulnori rhythms are well made up of the relaxation, tension, improvisation, escalating rhythms, and dynamic sound. Samulnori looks like two lovers exchanging sweet words in the natural forest. The push and pull between four instruments like a love quarrel. The author feels that the rhythms of the four instruments are like the whispers and cries of lovers. In conclusion, the silent or passionate rhythm of Samulnori feels like two lovers' tightrope love. The author thinks it creates a rich language of love.

Several explanations exist about the usage of disk-shaped bronze implements in the ancient society. Some argue that they were used as mirrors, others suggest percussion instruments, and still others bronze ornaments. Differences between disk-shaped bronze implements and mirrors with multiple knobs are that the former have no visible design, only one handle, and a sharp curvature unlike the latter with smooth curvature. The question is whether disk-shaped bronze implements excavated from Korean peninsula have any light reflecting function. To answer this question, I carefully studied the concave surfaces of disk-shaped bronze implements excavated from Goejeong-dong, Tongso-ri and Hapsong-ri sites. The main findings are as follows: (1) The concave sides of the disk-shaped bronze implements excavated from Goejeong-dong and Tongso-ri sites were highly polished, and they were as reflective as bronze mirrors. (2) The concave side of the disk-shaped bronze implement from Hapsong-ri site was unpolished, and it was different from bronze mirrors. (3) As for the convex sides of the disk-shaped bronze implements, they did not appear to have been polished with care. Considering the above findings, the disk-shaped bronze implements excavated from Goejeong-dong and Tongso-ri sites belong to the stage where they could act as both mirrors and instruments. On the contrary, the disk-shaped bronze implement from Hapsong-ri site can belong to the stage where it lost the function of being a mirror as the result of maintaining only its function as an instrument. Even though disk-shaped implements had two functions, it can be considered that the light reflecting function expanded the role of a mirror with multiple knobs and the sound function helped the engraved round bronze implement to be converted into an eight-armed bronze rattle. Since it has been reported that shamans used bronze mirrors as percussion instruments in their performances in Korean peninsula and Siberia, I propose a reconsideration of the usage of mirrors in the ancient East Asia. Although the essential function of a mirror is to reflect light, other possible usages involving important functions need to be further investigated.

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.
