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.

The purpose of this study was to investigate the effects postural changes on respiratory muscles and acoustic parameters of the children with spastic cerebral palsy. Nine children with spastic cerebral palsy who required assistance when walking were selected. The ages of the children ranged from 6 to 9 years old. The phonation of the sustained vowel /a/ and the voice qualities of each child such as fundamental frequency($F_0$; Hz), pitch variation (Jitter; %), amplitude variation (Shimmer; %) and noise to harmonic ratio (NHR) were analyzed by Multi-Dimensional Voice Program (MDVP). The muscle activity of three major respiratory muscles: pectoralis major muscle, upper trapezius muscle and rectus abdorminalis muscle, were measured by examining the root mean square (RMS) of the surface EMG to investigate the impact of changes in the adjusted sitting posture of each subject. However, the RMS of pectoralis major muscle showed a significant differences (p<.05). Secondly, there were no significant differences in $F_0$, Jitter and Shimmer between pre and post posture change, but there was a significant difference in NHR (p<.05). The data were collected in each individual; once prior and once after the sitting posture change. The data were analyzed by Wilcoxon signed ranks-test using SPSS version 14.0 for Windows. The findings of this study were as follows; Firstly, the RMS of upper trapezius and rectus abdorminalis muscle were not significant different between pre and post sitting posture changes. From the result, it is concluded that changes in the adjusted sitting posture decreases the abnormal respiratory patterns in the children with spastic cerebral palsy which is characterized by the hyperactivity of the respiratory muscles in breathing. Also, there is increased on the voice qualities in children with spastic cerebral palsy.

This survey was to identify voice symptoms and vocal-health service related experiences of occupational voice users(teachers, telemarketers, speech therapists). The 91.8% of teachers, 97.9% of telemarketers, 86% of speech therapists surveyed reported more than one voice symptom. The symptoms were classified as 9 categories(running a temperature, getting dry, dry and cough, pain, phlegm, tingled, hoarseness, cracks, swollen) and the most frequently reported from 3 groups was 'getting dry'. The 85.7% of teachers, 87.8% of telemarketers, 66% of therapists surveyed had no experience of vocal-health related services. The 19.6%, 19.9%, and 72% of each group reported they have heard both of 'voice/speech therapist'. The 36.8% of teachers and 43.6% of telemarketers answered they don't know how to use their voice efficiently and 45.3% of the teachers, 43.6% of the telemarketers, 28% of the therapists surveyed asked professional help for their voice. The result showed that most of the occupational voice users surveyed experienced voice symptoms but rarely knew professional vocal-health related services.

Objective : The purpose of this study is to determine whether An's breathing meditation qigong therapy (ABMQT) delivers bioenergy to the frontal lobe, prefrontal lobe, the olfactory tract in the mesolimbic pathway, olfactory bulb, CV22, CV21, olfactory area and vocal-related areas in Parkinson's disease (PD) patients to help improve olfactory disorders (anosmia) and vocal functions. Methods : The subjects of this study were 4 patients with idiopathic PD (3 males/1 female, 65.0±NA/68.7±10.2 years old). ABMQT was applied once a week, 120 minutes per session for 12 weeks in a non-invasive and noncontact manner, and the test before and after ABMQT application included olfactory impairment test the Korean version of Sniffin' stick test (KVSS), voice acoustic test, aerodynamic test, vocal handicap index (VHI-30), and auditory perception scale test tools. The results before and after the experiment were analyzed assuming a normal distribution, and a chi-square test was performed using a continuity correction, and the significance level was set to p<0.05. And the medical diagnosis and findings of the examiner (doctor in charge) before and after the experiment were described. Results : KVSS was significant as 0.2±0.5 and 9.0±0.0 before and after the experiment. There was no significant difference between the voice acoustic test FO and Jitter, the vocal aerodynamic test MPT, SP, AE, the vocal disorder index test, and the auditory perception test. However, the medical diagnosis findings of four study subjects showed that olfactory disorders, voice disorders, and laryngeal function were improved before and after the application of ABMQT. Conclusions : The breathing meditation qigong program showed significant effects on improving the olfactory disorders (anosmia) and speech function of each study subject. However, to produce meaningful results, it is thought that experiments involving a larger number of research participants are necessary, and additional blood and FMRI tests are conducted to verify metabolic activities and the olfactory neuron signal transmission system.

Presbyphonia is defined as voice change caused by aging. Since presbyphonia is one of the natural aging processes, the treatment should be considered for the patients complaining communication difficulties. The treatment should not only target on presbylaryngis, but also on underlying systemic conditions such as lung function, neurological diseases and medications. Therefore, the treatment for the patients with presbyphonia should be multidisciplinary including underlying disease control, voice therapy and surgical treatment. Although various experiments on treatment of presbylaryngis are currently being tried, repeated injection laryngoplasty is still playing an important role because presbyphonia is destined to get worse over time.

Excising part or all part of a larynx as a cancer operation results in changes that transgress anatomic, physiologic, psychologic, and social priciples. The quality of life of a patient's life after any given cancer surgery usually is regarded as a second-priority consideration after oncologic safety. With laryngeal surgery, excision of malignant disease typically results in change that significantly influence an individual for the duration of his or her life. Nonetheless, with appropriate rehabilitation the surgical side effects can be minimized to allow for an excellent quality of life. Successful conservation surgery for laryngeal cancer requires careful interdependent selection for patients, lesions and procedure. The technical goal is to minimize trauma to uninvolved tissue and to wisely utilized local tissues or tree flap for reconstruction, while insuring for oncologically sound procedure. Rehabilitation should aim to produce a glottal sound source if possible, however voice therapy to promote false vocal fold vibration and arytenoid to epiglottis source of vibration can produce very satisfactory phonatory results.
