尤里·谢迪赫链球世界纪录成绩的运动学分析

简介在1986年德国司徒加举行的欧洲锦标赛中,尤里谢迪赫(苏)创造了86.74米的链球世界纪录。他曾取得过下面一系列的成绩:83.94—85.28—85.46—86.74—86.68—86.62米,1986年6月在爱沙尼亚塔林,他的两次投掷成绩都超过了当时的世界纪录。其成绩高度的稳定性以及在后来几年中没有其他链球运动员可以接近这一远度的事实,使得教练员们及体育科研人员对其最佳投掷成绩的评价极为感兴趣。     

Introducing computer literacy skills for physicians

Computers are integral to medical practice, education, and research. While medical students learn computer skills during their training, many practicing physicians do not have the same computer experience. To familiarize this group with the exciting developments in medical informatics, the Himmelfarb Health Sciences Library and Department of Computer Medicine at the George Washington University Medical Center organized a workshop "Introducing Your Office Computer!" for attending physicians. The workshop featured a short lecture/video presentation on computer applications in medicine followed by a "computer fair" of five computer applications. Eleven physicians attended the workshop. Feedback was very positive; many called later to request more detailed instructions on using the programs demonstrated. It was a valuable experience for the staff, and new bridges were built between departments and clients.
