While most associations in town spend much of their time organizing services for members or lobbying Congress, one local group actually takes its cause to the streets and into the video-game parlors.

Over the past year, the Alexandria-based American Amusement Machine Association has helped the FBI carry out several "sting" operations, including one on Washington's 14th Street corridor that resulted in the arrest of five video game counterfeiters last year.

The AAMA continues to nab counterfeiters through undercover operations set up by its Copyright Enforcement program, but the group currently is concentrating on stopping pirated video games at the nation's borders. "We must help Customs defend against these counterfeiters," said the AAMA's executive director, Glen Braswell.

Most recently, the AAMA has assisted the U.S. Customs Service in producing a training film to help its agents identify pirated video-game equipment. The film, which the AAMA says should be distributed by early November, calls the counterfeiting problem "rampant" and offers clues ranging from how to spot missing computer chips on a circuit board to the type of shipping crate generally used by counterfeiters.

Industry statistics show that 90 percent of all video games in this country are imported from Japan, Taiwan and, most recently, Korea. The FBI reports that almost half of all video games in operation are counterfeits. The distribution of illegal video games costs legitimate video-game manufacturers, distributers and operators in this country an estimated $400 million annually, the association said. PROFESSIONAL

Recent growth in the health-care industry has resulted in the expansion of related nonprofit groups such as the American Association of Homes for the Aging, which recently formed a communications division to handle its increased membership. Sheldon L. Goldberg, executive vice president, cited the "dramatic growth in AAHA over the past two years and an ever larger number of activities in all areas of the association requiring communication supports" as reasons for the expansion. Evelyn L. Haught will direct the new division for the 2,600-member organization of nonprofit homes and services for the elderly. Haught most recently managed her own Washington-based marketing firm. She also has held major executive positions with both the International Franchise Association and the American Movers Conference. Haught will be assisted by Deborah A. Cloud, manager of public relations; David K. Krohne, manager of communications services; Sally S. Inada, communications associate and editor of the asssociation's newsletter; and Bettye J. Collins, secretary and staff assistant.

Another association representing the nursing home industry, the Maryland Association of Non-Profit Homes for the Aging Inc., has elected Ann MacKay of Columbia, Md., as its executive vice president. MacKay is the first full-time staff member for the group, which represents 50 nursing homes and retirement communities across Maryland. Before her appointment, MacKay was employed by Manor Healthcare Corp., as quality assurance manager for nursing services.

Anne Greenglass, former meetings director of the National Association of Wheat Growers, has been appointed director of conference services for the American Society of Training and Development. Greenglass will organize ASTD's national conference, which last year was attended by 4,500 people, making it the largest training and development event of its kind in the world. The 1986 conference will be held in St. Louis in May. TRADE

The Pharmaceutical Manufacturers Association has appointed two government relations professionals to represent the pharmaceutical industry on Capital Hill. William M. Corcoran, former administrative assistant to Sen. John H. Chafee (R-R.I.) and Michael L. Reed, a private legislative affairs consultant, will assist E. Geoffery Littlehale, PMA's vice president for government relations, in activities with members of Congress and their staffs.

The American Advertising Federation has appointed Wallace S. Snyder, formerly advertising practices director at the Federal Trade Commission's Bureau of Consumer Protection, as senior vice president in charge of government relations for this national advertising industry trade association. Snyder, a 16-year veteran of the FTC, succeeds Daniel Jaffe, who has been named Washington office director for the New York-based Association of National Advertisers.
