Participants were community dwelling older and younger adults. Toe vertical force during the OLS was recorded using a plantar-pressure distribution system, and the vertical forces in the hallux, little toe, and the first and fifth metatarsophalangeal (MP) joints were analyzed. A cross-correlation function was performed to examine the coordination between toes and between COP movement and four regions of the foot. The cross-correlation functions showed no significant difference in coefficients between toes. The OLS duration in the older adults was significantly correlated with the coefficient between the medial-lateral component of the COP and the first MP region. This study suggests that it is important to press the first MP region appropriately relative to COP movement to maintain the OLS.展开更多

The operation, codenamed Cobra II. was co-or- ganized by China, the United States, South Africa. the Lusaka Agreement Task Force （LATF）, the ASEAN Wild- life Enforcement Network and the South Asia Wildlife Enforcement Network. along with the support of the Convention on International Trade in Endangered Species of Wild Fauna and Flora （CITES）, the World Customs Organization and Interpol. The global crackdown focused on key species that are subject to illegal trade and achieved ＂excellent＂ results, according to john E. Scanlon, Secretary General of the CITES.展开更多
