The research investigated 150 non-English majors through a questionnaire in a higher vocational college. The result indicates that the interrelationship among understanding, memory and oral expression in listening classes which are determined by the listening materials and teaching method directly influences students' listening proficiency and speaking ability. It is suggested that some strategies to be used to foster students' abilities in these three areas so as to improve their listening ability.展开更多

The etiology of OA includes joint injury, obesity, aging, and heredity. However, the detailed molecular mechanisms of OA initiation and progression remain poorly understood and, currently, there are no interventions available to restore degraded cartilage or decelerate disease progression. The diathrodial joint is a complicated organ and its function is to bear weight, perform physical activity and exhibit a joint-specific range of motion during movement. During OA development, the entire joint organ is affected, including articular cartilage, subchondral bone, synovial tissue and meniscus. A full understanding of the pathological mechanism of OA development relies on the discovery of the interplaying mechanisms among different OA symptoms, including articular cartilage degradation, osteophyte formation, subchondral sclerosis and synovial hyperplasia, and the signaling pathway（s） controlling these pathological processes.展开更多
