This study was to investigate the effects of percussion program on depression and self-esteem for the elderly lived in residential care. 12 older adults participated in the 40-min. percussion program for 4 weeks(10 sessions). The percussion program consisted of three steps; 1) introduction for creating rapport and relationship, 2) process for mood induction and increasing interaction, and ending for increasing self-achievement and confirming the changed mood. Korean Geriatric Depression Scale (KGDS) and Self-Esteem Scale (SES) were administered before the first session and after the completion of the program. Results showed statistical significance (p<.05) in KGDS (p=.020) and SES (p=.025). Findings imply that percussion program can induce positive changes in depression and self-esteem for elderly in the residential care, and more depressed elderly group may have better outcome in percussion playing. Future studies should consider various levels of depression among elderly, and design the program to be more sensitive to the level of functioning.

The purpose of this research was to find out the effect of chest physiotherapy on the amount of tracheal secretion and $PaO_2$. After changing position of the neurosurgical patients who had tracheostomy cannula, experimental treatments were applied as bellows, manual chest percussion on groupI, chest percussion and manual chest vibration on groupII, chest percussion and mechanical chest vibration on groupIII were done. After these trials, we have analyzed the efficacy of each procedures comparing the group differences in the quantity of tracheal secretion and $PaO_2$. Target samples were sixty patients aged between 20 to 60 who have tracheostomy state and decreased consciousness status that were admitted in NICU of a university hospital from June 1 to August 31, 1999. They assigned randomly into three experimental groups. To compare the effect of each interventions, tracheal secretion quantify was measured and $PaO_2$ was analyzed via arterial blood gas analyzer. The data were analyzed by ANCOVA of 5% significance level using SPSS P/C program. The results were as bellows. 1) The first hypothesis 'There is a difference In the quantify of the secretion among GroupI, GroupII and GroupIII' was accepted.(F=29.27, p=0.00) 2) The second hypothesis 'There is a difference in $PaO_2$ among GroupI, GroupII and GroupIII' was rejected.(F=1.71, p=0.19) From this study results, positional change and manual chest vibration including chest percussion were the most effective treatment to get maximum amount of tracheal secretion and it was confirmed that mechanical chest vibration also made much better effect than sole chest percussion method. Therefore, we concluded that the mechanical or manual chest vibration with chest percussion is more effective respiratory care method than the sole chest percussion.

Purpose: Post-burn pruritus is one of the most prevalent complications experienced by burn patients. Though medications are prescribed for pruritus, managing this condition can prove challenging. The aim of this research was to develop and disseminate non-pharmacological self-management educational resources, and subsequently evaluate the effectiveness of implementing a percussion therapy approach. Methods: A one-group pretest-posttest design was employed to evaluate the effect of percussion therapy on one hundred patients, all of whom had suffered deep second-degree burns and undergone skin graft surgery. Variables such as the severity of pruritus, distress caused by pruritus, and satisfaction with pruritus treatment were scrutinized. A paired t-test was conducted to compare these variables before and after the intervention. Results: The majority of participants were diagnosed with third-degree burns, and the average Total Body Surface Area (TBSA) affected was 25.2%. Post-test results revealed a marked reduction in both severity and distress caused by pruritus. The intervention led to significant decreases in average severity and pain due to itchiness, and an increase in the satisfaction level following the application of percussion therapy. Conclusions: The implementation of the percussion was identified as effective in diminishing post-burn pruritus, alleviating pruritus-associated pain, and enhancing satisfaction with pruritus treatment. The percussion approach presents itself as a non-invasive, non-pharmacological strategy for managing pruritus in burn patients.

Purpose: This study investigated the effects of chest physiotherapies on intensive care unit patients mechanical ventilated. Methods: Good lung down position, chest percussion, postural drainage was applied to patients who admitted to ICU. Each patients divided into four groups and each group received different treatments. Sputum amount, lung compliance, tidal volume and oxygen saturation were measured before treatment and immediately, and time flowing. Data was analyzed with frequency, percentage, ANOVA and paired t-test using via SPSSWIN 12.0 program. Results: There were significant differences in variables each characteristics of subjects. Chest percussion increased tidal volume, static lung compliance for the mean time. Desaturation related to suction. Conclusion: Chest percussion influences on lung compliance. Based on this study results and limitation, this study suggests repeated studies in various groups

Vital pulpotomies by conventional method were done in 120 male and female cases between the ages of 20 and 60 who visited to SNUDH. The pulpotomized surfaces were covered by FR paste and clinical symptoms were carefully examined 1 week and 4 weeks later. The results were as follows; 1. There was no distinct difference between male and female as a whole, and pain to cold and hot or percussion was increased by aging. 2. Incidence of pain to cold and hot or percussion in group examined 4 weeks later was slightly increased than in group examined 1 week later. 3. There was no case of pain to cold and hot or percussion over all ages after 1 week, but were 5 cases (male 2, female 3) in 40 age, and were 3 cases (male 1, female 2) in 50 age after 4 weeks. 4. In 20 and 30 age, there was no case of pain to cold and hot or percussion after 4 weeks, also.

The purpose of this study was to compare chest percussion with chest vibration in brain injury patients. 30 patients in SICU of one general hospital in T city were randomely divided by 3 groups and the arterial oxygen tension(PaO2) and the retained secretion were measured. The chest vibration was done among the first group, the chest vibration by hand after the chest percussion was done among the second group and the mechanical chest vibration after the chest percussion was done among the third group. The data was analyzed using SPSS 7.0(5% significance) and the results are below. 1) It was adopted the hypothesis that the amount of retained secretion of endotracheal suction after stopping the actions among the first, second and the third groups is different from each other.(F=41.62, p=0.00) 2) It was rejected the hypothesis that the arterial oxygen tension(PaO2)s are different from each other among the first, second and third group.(F=1.22, p=0.31) The amount of the retained secretion after chest percussion, chest vibration by hand or mechanical chest vibration was significantly different from each other. Therefore, chest physiotherapy could be regarded as the effective nursing intervention for the unconscieus patients who have the inappropriate airway cleaness and it was more effective to be together than to be alone.

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.
