Recently, music therapy is widely used for various kinds of diseases. Music therapy has beneficial effects on emotional disorder and neuropsychiatric diseases in particular. This study was performed to evaluate the effect of singing on physiologic changes. We checked peripheral oxygen saturation and heart rate as indices of physiologic changes. The subjects were 19 control and 30 test group who were registered on the D welfare center for the elderly and agreed to join this study. They had been singing regularly for 6 months. The data were collected just before and after the singing. Data were analyzed with mean, t-test, and paired t-test using SPSS $PC^+$ program. The results were as follows: 1. Heart rate of the singing group decreased significantly after singing.(p<0.05) 2. Peripheral oxygen saturation of the singing group increased significantly after singing.(p<0.05) In conclusion, singing, a kind of aerobic exercise, has beneficial effects on cardiopulmonary system.

Background and Objective : Classical singing students who have received in systematic voice training appeared distinctive voice characteristics compared to normal people who have not received in systematic voice training. The purpose of this study was to determine the correlation between acoustic parameters and Electroglottography(EGG) parameters in two groups(ordinary college students vs. classical singing students group). Materials and Methods : The 80 ordinary college students and 65 classical singing students participated in this study by utilizing Dr. speech program to obtain acoustic measurements and physiologic measurements simultaneously. The Pearson correlation coefficient was used to find the correlation between acoustic parameters and EGG parameters in two groups(ordinary college students group and classical singing students group). Results : The results of the study were as follows : First, there was no correlation between Jitter and EGG Jitter in ordinary college students group, but there was strong correlation between Jitter and EGG Jitter in classical singing students group. Second, there was no correlation between Shimmer and EGG Shimmer in ordinary college students group, but there was strong correlation between Shimmer and EGG Shimmer in classical singing students group. Third, there was no correlation between Harmonic to Noise Ratio(HNR) and EGG HNR in ordinary college students group, but there was strong correlation between HNR and EGG HNR in classical singing students group. Finally, there was no correlation between Normalized Noise Energy(NNE) and EGG NNE in two groups.

The purpose of this study was to determine whether the Korean Singing Voice Handicap Index (K-SVHI) was suitable for singers in other genres than vocal music to assess their vocal problems subjectively. Twenty six college students majoring in vocal music and twenty six students majoring in applied music were included in the study. They were divided into G0 and G1 in voice quality using the GRBAS scale during the tasks of singing. K-SVHI was divided into three sub-areas (Physical, Functional, and Emotional). In the singing task, both groups showed no significant difference between K-SVHI scores by G scale. In the reading task, the vocal music group had significantly higher K-SVHI in G0 than in G1 in K-SVHIs by G scale, while the applied vocal music group had significantly higher K-SVHI in G1 than in G0. Also, the two groups were not significantly different in G0, G1 in the singing task while the vocal music group showed higher K-SVHI than the applied vocal music group in G0 in the reading task. In addition, the vocal music group had higher K-SVHI than the applied vocal music group in G1 in both tasks. As comparing by groups in three sub-areas of K-SVHI, significant differences were found in the Emotional and Functional area. Those results showed that singers felt their voice problems differently by musical genres, which means that K-SVHI may not be a proper tool for evaluating voice handicap of singers in diverse voice music genres.

본 연구는 성인지적장애인의 노래부르기 시 음도산출 특성을 알아보고 이를 대상자의 합창경험 유무에 따라 비교하였다. 연구대상자는 모두 남성으로 장애인 합창단에서 활동하고 있는 12명과 장애기관을 이용하고 있으며 합창경험이 없는 9명의 성인지적장애인을 대상으로 진행하였다. 음도산출 특성을 비교하기 위해 Praat을 사용하여 편안한 음역대에서 <생일 축하> 노래를 부르도록 하여 녹음하였고, 음도 도약이 포함된 특정구간('합니다-사랑하는')을 발췌하여 음절별 개별 산출음도를 비교 분석하였다. 연구결과, 합창단원 그룹의 경우 음역대가 넓고 높은 것으로 나타났으며, 최저음과 최고음에서는 모두 합창단원 그룹이 더 높은 것으로 나타났다. <생일 축하> 노래 중 구간에서의 개별 음절별 산출음도를 분석한 결과, 기대음도와 실제 산출음도 간 차이가 있었으며, 합창단원 그룹의 음도산출정확도가 모든 음절에서 더 높은 것으로 나타났으며, 음절 '다'와 '하' 완전 5도, 완전 8도에서 통계적으로 유의한 것으로 나타났다. 또한, 상대적 음도산출치의 경우, 음절 '니','다', '하', 완전5도, 완전 4도, 완전 8도에서 집단간 통계적으로 유의미한 차이가 나타났으며 합창단원 그룹의 음도산출 정확도가 더 높은 것으로 나타났다. 선율윤곽의 경우 개인이 부른 멜로디의 음도가 얼마나 기대음도에 유사하게 진행되는지를 시각적으로 보여주는 것으로 합창단원의 경우 음도산출 정확도의 수준에 관계없이 기대되는 선율진행의 윤곽과 유사한 형태로 나타났다. 이처럼 합창단원 그룹의 확장된 음역대와 음도산출 정확도는 일정수준의 노래 부르기 지속 시 음도 훈련이 가능함을 보여주는 결과로 볼 수 있으며, 향후 성인지적장애인의 노래 부르기 능력에 관한 지속적인 연구가 필요함을 시사한다.

This study was conducted for the evaluation of the effects of singing program combined with physical exercise on the physiologic changes, perception function and degree of depression. The subjects were the members of elderly women's glee club in D care center for the elderly, who have been singing for more than 6 months. 30 members were allocated to study group and 30 to control group. The singing program designed for both physical therapy and music therapy was consisted of initial physical exercise, singing art songs and classical song and the finishing physical exercise. This program was performed twice a week and about forth minutes was consumed for one session. We checked the heart rate, peripheral arterial oxygen saturation, perception function and degree of depression before and after the program. We used a pulse oxymeter to check the heart rate to oxygen saturation and a questionnaire for the evaluation of perception function and degree of depression. We need SPSS program for data analysis. The results of the investigated personnel complying with general characteristics were analyzed by frequency, two groups by t-test, data before and after the program by paired t-test, respectively. The results were as follows. 1) Heart rate after the program was significantly lower than that before program in test group(p<0.05). 2) Peripheral oxygen saturation after the program was significantly higher than that before the program(p<0.05). 3) Ability to match the right sign with a certain predetermined number was improved after the program. The frequency of wrong matching the sign with number before program was 30. But the frequency was decreased to 8 after the program. 4) Ability to calculate was improved after the program. The frequency of wrong calculation before the program was $1.10{\pm}1.94$. But the frequency after the program was decreased to $0.97{\pm}1.84$. 5) The degree of depression after the program($2.07{\pm}0.49$) was significantly lower than that before program(p<0.001). These results show that singing program combined with physical exercise improves the oxygen delivery to peripheral circulation, stability of heart function, the perception function(calculating and matching ability) and decreases the degree of depression. In conclusion, singing program combined with physical exercise can be used for the effective measure to improve the health of elderly and prevent dementia.

Purpose: This study was conducted to describe the risk of dysphagia and to evaluate the effects of a singing intervention for women elderly in community. Methods: One-group pre test-post test design was used. The subjects were 29 women over the age of sixty and residing in a local area. A singing intervention consisted of breathing, vowel production and singing. The one hour intervention occurred once a week for eight weeks. The variables of dysphagia risk, a swallowing test, and nutritional status were measured. Analysis was done by paired t-test. Results: There was a significant decrease in the score of dysphagia risk (p<.001). There were significant increases in the swallowing test scores [modified water swallowing test (p=.032), food test (p=.001)]. There were no significant differences in nutritional status (triceps skin fold thickness, mid arm muscle circumference). Conclusion: The findings support that a singing intervention can be helpful in reducing the risk of dysphagia may improve deglutition for the women elderly. These results suggest that this study may contribute to the use of a singing intervention for women elders with dysphagia risk.

Habitual speaking fundamental frequency (sF0) plays an important role in determining the voice classification, which can be presented differently depending on the vocal fold length and language habits. The purpose of this study, therefore, was to compare the differences in sF0 for voice classification and closed quotient between speaking and singing. Seventeen singers (7 sopranos, 5 tenors, 5 baritones, mean age 25.1 years) with no evidence of vocal folds pathology were participated. sF0 and closed quotient (CQ) both in speaking and in singing (A3-A5 with soprano, A2-A4 with tenor and baritone) were measured using SPEAD program and electroglottography. No significant differences were observed for sF0 between tenor and baritone groups (p> 0.05). However, CQ in singing was significantly different among three groups (p< 0.05), but CQ in speaking was not (p> 0.05). Furthermore, CQ was significantly different with both soprano (p< 0.01) and tenor groups ((P= 0.02) whereas baritone group revealed there is no difference when compared between speaking and singing. No significant differences in sF0 between tenor and baritone participants may result from decision-making for voice classification by experience and should measure sF0 before determining the voice classification.

Objectives : The purpose of this study was to systematically analyze and compare the acoustic characteristics of vocal major students with vocal nodule when singing. Materials and Methods : Ten sopranos with vocal nodule, who have never been treated due to voice problems, were the subject group. Twenty healthy sopranos major students were the control group for this study. The vocal nodule was confirmed by stroboscopy and the acoustic and electroglottographic analysis was conducted on be groups. Additionally, an inquiry on usual voice problems during speaking and singing were performed on each of the groups. Results : The vowel /a/ was spoken and sung by sopranos of each group. There were no significant differences in Fo, jitter, shimmer, NHR at speaking and singing in either group. We did not register any significant differences of closed quotient and speed quotient in electroglottography for both groups at singing, but speed quotient was increased in subject group at speaking(p＜0.05). And the sopranos with nodule demonstrated voice fatigue(70%), strained and tired voice after long period of performance and conversation(60%) on inquiry. Conclusions : Although they had a vocal nodule, this group, who had a long period of voice training, did not present any differences in acoustic and electroglottographic problems during short performance, but, the vocalists noticed delicate voice problems after a long performance. We conclude that the voice training teacher and laryngologist must initiate voice management and speech therapy for vocal nodule, even if there is no specific abnormality in acoustic analysis.

Objectives : The purpose of this study was to systematically analyze and compare e acoustic sound structure of vocal major student's singing voice. Materials and Methods : The nineteen vocal major students were the subject group and healthy nineteen females were the control group for this study. The subject group was taken a strobovideolaryngoscopy by the use of flexible nasopharyngoscopy. And acoustic analysis was taken between two groups. Additionally the inquiry on usual voice problems and management was performed by thirty-six vocal major students. Results : The subject group presents many functional voice disorder findings such as AP contraction(44%), phase difference(36%) tremor(25%), posterior gap(17%), hyperadduction of vestibular fold(6%), and anterior gap(3%) on strobovideolaryngoscopy. And the vocal major students did reveal an enhanced number of high frequency harmonic partials when singing compared to the control group in the narrow band spectrum study. But there was no significant difference in jitter, shimmer and noise to harmonic ratio in both groups. Almost all vocal major students present a lot of voice problems in singing such as loss of high note(17%), loss of quiet voice(17%), effortful and tired voice(36%) etc on inquiry. And they always effort to prevent vocal dysfunction by the use of various type of method such as voice rest(28%), hydration(28%), gargling with salt(11%) etc. Conclusions : The vocal major students always take care of maintaining a good voice condition, but a lot of vocal major students revealed abnormal strobovideolaryngoscopic findings and they are absent in the conception of systemic and scientific voice management. Therefore, the young singers need a good voice training and voice therapy Program under the good ralationship of laryngologist and voice training teacher.

본 연구의 목적은 만성 뇌졸중 환자를 대상으로 악기연주 시 동반되는 노래부르기 과제의 유무에 따라 피로도 및 운동 수행력이 달라지는지 비교함으로써 뇌졸중 환자의 신체 재활 시 활용 가능한 악기연주 및 노래부르기에 대한 기초 자료를 제공하는 것이다. 연구 대상자는 서울시 소재 노인 복지관과 주간보호센터를 이용하고 있는 12명의 만성 뇌졸중 환자로, 실험 집단과 비교 집단에 각각 6명씩 무작위 배정하였다. 연구 진행 시 2회기에 걸쳐 실험 집단은 전자 드럼 연주와 함께 노래부르기를, 비교 집단은 전자 드럼 연주만을 수행하였으며, 각 집단에 따라 피로도, 운동자각도, 활동 참여도, 드럼 타력값을 비교 분석하였다. 연구 결과, 전자 드럼 연주와 함께 노래부르기를 한 실험 집단이 전자 드럼 연주만 실시한 비교 집단에 비해 피로도와 운동자각도가 낮은 것으로 나타났으며 집단 간 유의한 차이를 보였다. 전자 드럼 연주와 노래부르기를 복합 과제로 제시하였을 때 활동 참여도 역시 높게 나타남에 따라 향후 이를 사용한 음악치료 중재 시 뇌졸중 환자의 상지 운동에 긍정적인 영향을 미칠 수 있음을 나타냈다. 본 연구는 만성 뇌졸중 환자의 상지 운동 시 동반되는 노래부르기가 신체 운동에 대한 주의를 노래부르기로 전환시키고 참여 동기를 증진시켜 지속적인 움직임 유도 시에도 피로도 또는 운동자각도를 감소시킬 수 있음을 시사한다. 이러한 결과를 통해 신체 재활 시 반복적인 운동에 대해 긍정적으로 인식하고 운동 수행력을 높일 수 있는 복합적인 치료적 개입을 위한 기초 자료를 제시할 수 있을 것이다.
