Chronic mental-handicapped people are lacking in non-verbal expression such as eye contact, intonation, voice volume, facial expression, and gesture as well as the contents of speech, speak with a monotonous voice, fail to be vivid and clear in voice, and have absence of expression, thereby bringing about difficulty even for social adjustment and about low self-esteem. Accordingly, the purpose of this study was to examine effectiveness for enhancing self-expression and self-esteem by applying music therapy to the chronic mental-handicapped. The subjects were the chronic mental-handicapped who receive rehabilitation service at the community rehabilitation center, and who have over 10 years in the duration of disease. 1he music therapy activity was progressed with totally 14 sessions during 7 weeks with twice a week. This study confirmed t-test that is verification of difference in the mean, in order to examine difference between before and after music therapy in self-expression and self-esteem of the chronic mental-handicapped, and researched into qualitative case. The findings are as follows. First, as a result of score in self-expression scale, the significant improvement was shown after music therapy compared to before music therapy. The significant difference was indicated in verbal self-expression, phonetic self-expression, and non-verbal self-expression, which are its sub-spheres. Thus, the conclusion was obtained as saying that music therapy is effective for enhancing self-expression. Second, as a result of score in self-esteem scale, the significant difference was shown after music therapy compared to before music therapy. Thus, the conclusion was obtained as saying that music therapy is effective for enhancing self-esteem. Through the above results, the music therapy showed effectiveness of self-expression ability and self-esteem in the chronic mental-handicapped at the community rehabilitation center, thereby having been confirmed to be possibly utilized as rehabilitation program for the social skill ability and the social adjustment of the chronic mental-handicapped.

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.

Objective : Essential tremor(ET) is the most common movement disorder, however, there has been little agreement in the neurologic literature regarding diagnostic criteria for ET. Familial ET is an autosomal dominant disorder presenting as an isolated postural tremor. The main feature of ET is postural tremor of the arms with later involvement of the head, voice, or legs. In previous studies, it was reported that ET susceptibility was inherited in an autosomal dominant inheritance. As previous results, it would suggest that ET might be associated with defect of mitochondrial or nuclear DNA. Recent studies are focusing on molecular genetic detection of movement disorders, such as essential tremor and restless legs syndrome. Moreover, authors have analysed mitochondrial DNA(mtDNA) from the blood cell of positive control(PC) and ET patients via long and accurate polymerase chain reaction(LA PCR). Materials & Methods : Blood samples were collected from PC and 9 ET patients. Total DNA was extracted twice with phenol followed by chloroform : isoamylalcohol. For the analysis of mtDNA, LA PCR was performed by mitochondrial specific primers. Results : With this technique, deletions of large quantities were detected within several regions of mtDNA in ET patients except for D-loop and CO I regions. Conclusion : The authors believe that ET is a genentic disorder with deficiency of mitochondrial DNA multicomplexes and mitochondiral dysfunction could be one of major causative factors of ET. Mitochondrial dysfunction may play an important role in the pathogenesis and possibility of disease progression among familial group with ET patients.

Motor aphasia is an affection frequently caused by insult of the left middle cerebral artery and usually accompanied by a large lesion involving the Broca's area and the adjacent motor and premotor areas. Therefore, a patient with motor aphasia commonly shows articulatory disturbances due to failure of the motor programing of speech sound. Objective assessment and treatment of phonologic programing is one of the important aspects of speech therapy in aphasic patients. We analyzed the speech disorders acompanied with motor aphasia in a 45-year-old man using a computerized sound spectrograph, Visi-$Pitch{\circledR}$, and Multi-Dimensional Voice $Program{\circledR}$. We concluded that a computerized speech analysis system is a useful tool to visualize and quantitatively analyse the severity and progression of dysarthria, and the effect of speech therapy.
