Background : Many factors affect foot and ankle biomechanics during walking, including gait speed and anthropometric characteristics. This study examined the effect of walking speed on peak plantar pressure during the walking. Method : Thirty two normal healthy subjects (16 men, 16 women) were recruited. Peak plantar pressure was investigated using pressure distribution platforms (Pedoscan system) under the hallux heads of the first, second, and third metatarsal bones, and heel. Result : The results also suggest that slow walking speeds may decrease forefoot peak plantar pressure in patients with peripheral neuropathy who have a high risk of skin breakdown under the forefoot(p<0.05). Conclusion : The results also suggest that slow walking speeds may decrease forefoot peak plantar pressure in patients with restricted low extremity range of motion who have a high risk of skin breakdown under the forefoot.

Purpose: This study investigated the effect of electroacupuncture stimulation on changes in blood biochemistry in spinal cord injury (SCI) rats whose cords were damaged by 6-hydroxydopamine (6-OHDA). Methods: Twenty-one Sprague-Dawley adult male rats were assigned to one of three groups: normal (n=7), control (n=7) and experimental group (n=7). The experimental group received electroacupuncture (Es-160, ITO, Japan) for 15 minutes in the form of low frequency (2 Hz) stimulation to the zusanli point. After treatment, we observed motor behavior recovery using the inclined plane test. We also measured serum and CNS concentrations and activities of enzymes including creatine kinase (CK), alkaline phosphatase (ALP), and Immunoglobulin G (IgG). Statistical analysis was done using one-way analysis of variance (ANOVA). Results: Concentrations of CK, ALP and IgG were lower in the experimental group than in the control group. Functional recovery was evaluated by the maximal angle of the inclined board on which rats could maintain their initial position. This allowed us to monitor progressive locomotor recovery. The maximal angles of the inclined plane test were higher in the experimental group than in the control group (p<0.05). Conclusion: The results of this study showed that electroacupuncture to the zusanli point has a therapeutic effect on functional recovery after SCI.

인터넷 환경에서 실시간 서비스에 대한 제공을 위해 제안된 RTP(Real-time Transport Protocol)는 실시간 전송 프로토콜로서 스트림형 데이터 전송을 목적으로 한 프로토콜이다. RTP는 기본적으로 RTCP(Real-time Transport Control Protocol)와 쌍을 이루어 동작하며, RTCP는 현재 네트워크의 상태 정보를 전달한다. RTP는 종단 시스템에서 실행되고, 디멀티플랙싱을 제공하는 전송 프로토콜의 중요한 특성을 가지고 있다. 또한, TCP 같은 전송 프로토콜에서 제공하지 못하는 신뢰성과, 프로토콜에 정의된 흐름/혼잡제어를 제공한다. 본 논문에서는 RTP상에서 동작하는 Differentiated Service의 개념과 구조를 살펴보고, Differentiated Service상에서 효율적인 패킷전송을 위해 CBQ(Class-Based Queuing)을 사용한 패킷 전송 모델의 파라미터를 설정함으로써 각각의 서비스 큐를 적절하게 제어하고, WRR(Weighted Round Robin)과 PRR(Parket-by-packet Round Robin) 같은 패킷 스케줄링 기법을 통해서 모든 서비스 클래스들이 기아현상을 경험하지 않고 공평한 스케줄링이 이루어지도록 컴퓨터 모의실험을 통해 성능을 확인한다. RTP that is proposed supplement of real-time services on internet environment, as Real-time Transport Protocol, is the protocol that for the purpose of sending data of stream type. RTP and RTCP(Real-time Transport Control Protocol) basically work at the same time, RTCP serves with state information of network at present. RTP has important properties of a transport protocol that runs on end-to-end systems and provides demultiplexing. It also offer reliability and protocol-defined flow/congestion control that transport protocol like TCP can not provides. In this paper. we look around concept and construction of Differentiated service that run on RTP and by setting parameters of packet transfer method be used CBQ(Class-Based Queuing) for packet transfer on Differentiated service, each service queue controls properly through packet scheduling method, such as WRR(Weighted Round Robin) and PRR(Packet-by-packet Round Robin) all service classes do not experience the starvation and confirm the performance through computer simulation to achieve fairly scheduling.
