This study aimed to examine whether McConnell taping for deltoid inhibition affects the Electromyographic (EMG) activity of shoulder girdle muscles during arm elevation. Ten young healthy men were randomly assigned to an experimental and control groups of five men each. For the experimental group, we performed taping for deltoid inhibition on the skin over anterior and posterior deltoids with non-elastic specific tape, and sham-taping with non-elastic under-tape for the control group. Surface EMG measurements were performed three times (before, during and after the tapings) at upper and lower trapezius, mid-deltoid, and serratus anterior muscles while elevating dominant aim with loading and unloading conditions. In deltoid inhibition taping group, there were significant differences in EMG activity of mid-deltoid (p<.05) and serratus anterior (p<.05) muscles during arm elevation with loading. During arm elevation without loading, the EMG activity was significantly decreased for MD in the McConnell taping group (p<.05). The findings indicate that deltoid inhibition taping can modify the activation patterns in shoulder girdle muscles as well as in deltoid muscle. in clinical setting. it may be effectively used for the management of patients with shoulder dysfunction.

일반적으로 배사에 비해서 준설은 경제적 부담이 크기 때문에 배사를 효율적으로 운영하는 것이 중요하다. 본 연구에서는 2차원 하상변동 모형 인 Nays2DH를 이용하여 홍수기 운영수위에 따른 배사효율을 낙동강에 위치한 달성보를 중심으로 분석하였다. 분석결과, 가동보의 수 만큼 배사 수로가 형성되었으며, 배사수로 상류에는 퇴적이 발생하는 것으로 나타났다. 또한, 홍수기 운영수위를 EL. 14.5 m로 운영하는 것이 EL. 14.0 m로 운영하는 것에 비해서 배사효율이 약 4.6% 증가하여 퇴사가 약 4.5% 감소하는 것으로 나타났다. 본 연구에서 분석한 홍수기 운영수위에 따른 배 사효율의 변화를 고려한다면, 저수지 퇴사 저감 및 준설주기의 장기화가 가능할 것으로 판단된
