This paper investigates the possibility of exploiting haptic force-feedback technology for interacting with Nanta music. We use VR technologies including touch processing technologies and haptic devices to offer touch of cylinder objects and cup object to users. Haptic device is used to implement touch model in VR space. Matlab/Simulink and proSENCE Virtual Touch Toolbox of Handshake Inc. for experiment, are used as programing tools. Function needed to describe the movement of x, y, and z axis respectively are applied to delineate the natural movement of water in cup object modeled with 3D. A certain amount of water in cup object has the difference of sounds. In experiment, to perceive the appearance of 3D object by touch and to feel the tactile by touch are conducted with the effect of sound on Haptic perception. We also verify that it is possible to develop games or contents in VR space by using point.

Nanta means "tapping" using percussion instruments such as drums, which is the rhythm of Samulnori, a tradtional Korean music. Nanta speech rhythm intervention program was developed and applied for the children with limited speech sound production and investigated its effect. Nanta program provided audible stimulation, various sound loudness and beats, and rhythms. Nanta program consists of three stages : Respiration, phonation and articulation with the rhythm. Six children with language development delay participated in this study. Children were encouraged to explore sounds and beats and freely express sounds and beats. Along with the rhythm, children also were encouraged to produce speech sounds by increasing the length of syllables in mimetic and imitating words. A total of 15 sessions were conducted twice a week for 40 minutes per session. For exploring the effectiveness, raw scores from preschool receptive-expressive scales (PRES) and receptive-expressive vocabulary test (REVT) were obtained and compared before and after therapy. The results demonstrated that significantly improved receptive (p=.027) and expressive language scores (p=.024) in PRES and receptive (p=.028) and expressive (p=.028) vocabulary scores following intervention using Wilcoxon signed-rank test.These findings suggest that the nanta rhythm program can be useful for improving language development and vocabulary in children with limited speech sound production.

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.
