''This is probably the most satisfying championship for me. Celtic pride was in this building, but there was a little Laker pride, too.''

At the center of what the authorities have called one of the major spy rings in American history is the troubled family of John A. Walker Jr. It was family ties, the Federal Bureau of Investigation says, that helped Mr. Walker obtain some of the classified information he sold to the Soviet Union. And it was family turmoil, punctuated by a divorce nearly a decade ago, that apparently led to his arrest. Six months ago, Barbara Joy Crowley Walker, who had been left by her husband one year before the divorce, with four teen-age children to rear, turned her former husband in. With her 25-year-old daughter, Laura W. Snyder, Mrs. Walker told an F.B.I. agent on Cape Cod of her suspicions that her husband had been selling secrets to the Russians for about 16 years. Mr. Walker was arrested last month. Then came the arrests of Mr. Walker's son, Michael, a 22-year-old enlisted man aboard the aircraft carrier Nimitz, and his brother Arthur, a 50-year-old engineer for a local military contractor. A fourth man, Jerry A. Whitworth of Davis, Calif., was also charged in the case.

With its first foray into the United States car market less than a year away, the Hyundai Motor Company is a company in a hurry, pushing its workers to improve the way they build cars. At each stage on its assembly line here hang multicolored diagrams of car parts and assembly techniques, with a large red X marking the wrong way to perform that station's task. The factory in this southern industrial city is strewn with banners calling on workers to achieve 24-hour production and charts plotting the number of error-free vehicles made every day. High Stakes The stakes are high for Hyundai and other South Korean car makers. After years of relative obscurity producing cars for a small domestic market and exporting them mainly to other Asian countries, South Korean companies are getting ready to break into the United States, the largest market of them all.

An article in some editions of Sports Pages on Thursday, about the Mets-Dodgers game Tuesday night, inaccurately described the performance in the eighth inning by Dwight Gooden of the Mets. With the bases loaded, he struck out one batter on three pitches, got the next batter to foul out on the first pitch, then struck out the next batter on five pitches.

The Department of Defense has instituted what the military and civilian medical authorities describe as strict new measures to eliminate substandard care at military hospitals. The drive began after a small number of highly publicized incidents in which patients were killed or injured by negligent military doctors. Some of the most prestigious military hospitals have been caught up in malpractice cases. Internal audits have reported serious deficiencies in the appointment and evaluation of doctors, and a survey of more than 19,000 patients last year found that most families were dissatisfied with military care, ranking it below civilian care in all respects. Leaders Had Resisted The reform effort, fueled by extensive publicity about malpractice cases, is progressing despite initial resistance on the part of some leaders in military medicine, said Dr. William E. Mayer, Assistant Secretary of Defense for Health Affairs.
