The evolving role of ergonomics in the workplace is the focus of this year's National Ergonomics Conference and Exposition, scheduled for Dec. 10-13 in Las Vegas. In keynote addresses senior ergonomics professionals from Wal-Mart and Microsoft Corp. will explain how ergonomics is expanding its boundaries within their organizations to address material handling, workstation design, product development, and productivity, as well as its traditional role as an instrument to enhance workplace health and safety. Full-day workshops and scores of seminars address topics such as cost justification and risk assessment, and share the latest techniques and proven strategies to generate positive returns on the investments made in ergonomics. More than 100 exhibitors also will be on hand to present their latest products, services, and technologies. For more information, visit www.ergoexpo.com or call 212-370-5005.
