PURPOSE: The PURPOSE of this study was to analyze the effect and examine the feasibility of an intervention of ankle strategy exercise on balance of patients with hemiplegia. METHODS: The subject were randomly allocated to three groups: ankle strategy exercise (group A), balance exercise (group B) and control (group C). Group A was received the conventional physical therapy plus ankle strategy exercises for 20 minutes in one session . Group B was received the same conventional physical therapy plus balance exercises for 20 minutes in one session. Two active groups were performed in the session 3 times a week, for a total of 6 weeks. and Group C was only received the same conventional physical therapy. Balance test was assessed using center of pressure (COP) in the anteroposterior (AP), mediolateral (ML) direction, Berg balance scale (BBS) and Timed Up and Go Test (TUG). RESULT: All groups showed improvements in balance parameters. In especial, the Group A was statistically significant differences in almost part evaluation items and showed more improvements in BBS and TUG parameters than Group B and Group C. and moving distance of M-L COP is more improvements than Group B. CONCLUSION: Ankle strategy exercises had more influence on balance than balance exercises and neurodevelopmental treatment.

본 논문에서는 다계층 브로드캐스트 통신 환경에서 주목받는 비균등 오류정정기법(UEP)에 대하여 기본 이론을 설명하고 그 효과와 응용 분야를 소개한다. 또한 현재까지의 UEP 기술의 연구 동향을 표준 적용 현황과 관련 논문의 소개를 통해 조명하고, 이를 통해 표준화 전망을 비롯한 앞으로의 활용 방안을 제시한다. In this paper, we introduce basic theories, effects and applications of the unequal error protection (UEP) system that is expected to play a major role in the future multi-layered broadcast system. Also we show results of surveys on the various previous studies and standards about the UEP systems, and we give prospects of standardizations and future applications of UEP based on the surveys.
