최근, 많은 연구자들이 KLT를 이용한 통계적 처리방법으로 화자인식을 수행하고 있으나, 통계적 처리방법의 개인성 포함정도와 음성의 동적인 발성속도는 화자인식율의 저하요인이 되고 있다. 본연구에서는 각 화자의 직교인자에 개인성을 강조하기 위하여 화자의 고유치를 가중치로 한 가중직교인자와 음성의 동적인 시간특성을 정규화하는 DTW의 최적경로를 이용한 화자인식방법을 연구하였다. 이방법을 확인하기 위하여 종래의 통계적 처리에 의한 화자인식, 최적경로와 최적경로와 가중직교인자를 이용한 화자인식의 결과를 비교한 결과, 종래의 방법보다 우수한 화자인식율을 얻어 그 유효성을 확인하였다. Recently, many researchers have studied the speaker recognition through the statistical processing method using Karhunen-Loeve Transform. However, the content of speaker's identity and the vocalization speed cause speaker recognition rate to be lowered. This parer studies the speaker recognition method using weighted orthogonal parameters which are weighted with eigen-values of speech so as to emphasize the speaker's identity, and optimal path which is made by DWP so as to normalize dynamic time feature of speech. To confirm this method, we compare the speaker recognition rate from this proposed method with that from the conventional statistical processing method. As a result, it is shown that this method is more excellent in speaker recognition rate than conventional method.

Purpose: The purpose of this study was to provide basic data for the effectiveness and the necessity of home visiting physical therapy through examining performance ability and functional changes in daily life activities by investigating the life of disabled persons living at home. Methods: After selecting 100 people with physical disabilities greater than level 3 and brain damage related disabilities living in Youngam-Gun, we conducted mobility tests according to a Modified Bathel Index (MBI), the Berg Balance Scale (BBS), and floor and bed movements? for Activities of Daily Living evaluation. We did this before the experiment and after doing home visiting physical therapy for 90 minutes at a time, once a week for 6 months Results: 1) Persons who live in a bed are higher than those who live in a floor. There was a significant difference between persons who live in a floor and those who live in a bed in the change in MBI and BBS scores after home visiting physical therapy. 2) Those with a musculoskeletal disorder had a significantly different change in MBI and BBS according to the type of disease and kind of disability. Those with neuropathy had a significantly different change in MBI. Those with physical disabilities showed a significant difference in MBI and BBS. Conclusion: A home visiting physical therapist can cause an improved performance ability and lead to the ability of disabled persons living at home to carry out activities of daily livingin a large part and the study for brain lesion disabilities except physical disabilities and stroke which occupy large proportion of disabled persons should be done.

Purpose: This study was conducted in order to suggest an effective method of daily life movement training for stroke patients by comparison and analysis of the biomechanic characteristics of sitting up from a lying posture in stroke patients and healthy elderly participants. Methods: Fifteen stroke patients and 15 age-matched elderly participants were included in the study. The movement of sitting up from a lying posture was divided into three stages, and the differences in muscle activity in the sternocleidomastoid (SCM), rectus abdominis (RA), external oblique (EO), and rectus femoris (RF) during the movement were analyzed. Results: Subjects in the experimental group showed slower speed than those in the control group. In the neck joint, the change of angle in movement showed a larger decrease at all stages in the experimental group than in the control group; the movement also decreased in stages I and II in the upper trunk joint. The movement also showed a statistically significant decrease in stage II in the lower trunk, pelvic, and hip joints. The SCM showed higher activity in the control group than in the experimental group, showing a statistically significant difference; the RA showed high activity in the experimental group. The RF showed higher activity in the control group than in the experimental group, showing a statistically significant difference. Conclusion: From the results obtained above, increasing movements in the neck, pelvic, and hip joints and strengthening of lower body muscles are required in order to improve the ability for getting up from a lying posture in stroke patients.

Purpose: The purpose of this study was to investigate the effect of closed kinetic chain exercise using EMG-biofeedback for selective training of the vastus medialis oblique on functional ability and Q-angle in subjects with patellofemoral pain syndrome. Methods: Thirty participants who met the criteria were included in this study. Participants were randomly allocated to the control group (Group I, n=10), closed kinetic chain exercise group (Group II, n=10), and closed kinetic chain exercise using EMG-biofeedback group (Group III, n=10). Intervention was performed in three groups, three times per week, for a period of six weeks. Kujala patellofemoral score and Q-angle were measured before and after the experiment. Results: Some significant differences in kujala patellofemoral score were observed in group II and group III, compared with group I (p<0.01). There was no significant difference on in Q-angle at knee flexion angle $0^{\circ}$. However, some significant differences in Q-angle at knee flexion $60^{\circ}$ were observed in group III, compared with group I (p<0.01). Conclusion: Closed kinetic chain exercise using EMG-biofeedback that provides real-time biometric information on selected muscles in order to increase the efficiency of treatment may be helpful in improvement of functional ability and Q-angle in patellofemoral pain syndrome.

Purpose: We investigated the effect of postural stability and balance with foot orthotics in hemiplegic patients. Methods: The subjects enrolled in this study were 16 hemiplegic patients who were examined for balance ability, weight distribution, and limits of stability with or without foot orthotics insole. Balance was measured according to a stance position by BIORESCUE: static balance open eyes (SEO), static balance close eyes (SEC), dynamic balance open eyes (DEO), dynamic balance close eyes (DEC), right and left weight distribution (RLWD), anterior and posterior weight distribution (APWD) and limit of stability (LOS). The data were analyzed with SPSS window version 18.0 (IBM Co., Armonk, NY, USA). Results: The results were of significant changes to the SEO (p<0.05), RLWD (p<0.05), APWD (p<0.05), and LOS (p<0.05). The SEC, DEO and DEC were not found to be statistically significant. Conclusion: It was found that foot orthotics affected the balance for hemiplegic patients. Therefore, it is thought to help fall prevention to measure the balance ability.

We are approaches various painful diseases in clinic. Although same disease, it is different to acute, subacute and chronic stage of disease. Therefore, to understanding of tissue anatomy, pathology and physiology is necessary to under-standing pattern of diseases. It is duty work that choice of hot or ice, electrotherapy, choice of adaptable frequency and mathod of exercise therapy etc. During treatment it is important method to choose to treat the client. As treating the client by exercising or treating when the client is resting and seeing if anything else is a problem etc. So what I have approached some of the treatment that a physical therapist could miss during treatment.
