When Japanese companies first began manufacturing in this country, many people smiled at oddities like pre-work exercise, but analysts were struck with the efficiency of the Japanese management style. Now, the Koreans are coming, setting up their own factories and bringing their version of management ''harmony.'' Dozens of South Korean corporations have already opened offices in the United States, and two have begun manufacturing operations. The Lucky-Goldstar Group opened a color television factory in Huntsville two and a half years ago, and is now bustling with expansion plans. Last fall the Samsung Group also began producing color televisions, at a factory in Roxbury Township, N.J.

CBS stock plunged nearly $10 in heavy selling yesterday amid widespread Wall Street rumors that Ivan F. Boesky, the multimillionaire Wall Street arbitrager, was quietly selling his stock, using others to hide his own movements. At the heart of yesterday's setback was the news that CBS had sued Mr. Boesky on the ground that he had built his 8.7 percent stake in the company by violating Federal regulations requiring him to put up at least half the money in cash. The suit further contended that he failed to disclose that he had tried to sell his stock back to CBS or to say that he had had conversations about CBS with Ted Turner, the maverick Atlanta broadcaster, and other unidentified individuals.

THURSDAY, APRIL 11, 1985 Companies An $18-a-share offer for control of Uniroyal was made by Carl C. Icahn, the Wall Street financier. The rubber company's stock closed at $18.75, indicating that the market expects a higher bid to emerge. Shareholders are scheduled to vote Tuesday on measures intended to make a takeover virtually impossible. Mr. Icahn, who holds about 10 percent of Uniroyal, is leading a proxy fight to defeat those measures. (Page D1.) CBS stock plunged in heavy trading amid widespread rumors that Ivan F. Boesky was reducing his holdings. (D1.)

Pressing trade issues are reshaping the political lineup in the United States as Democrats and Republicans maneuver for advantage while trying to deal with an influx of imports from Japan and other countries. The Democrats, who until last year championed legislation to restrict imports, have shifted to blaming the Administration's fiscal policy and the bloated dollar for the nation's record $123.8 billion trade deficit last year. One reason, analysts say, is that the Democrats smell blood. Twenty-two Senate Republicans face re-election next year, and they could be vulnerable to the Administration's enthusiasm for free-market solutions to the severe problems of the dollar's high value.

A judge issued a temporary restraining order last night barring Columbia University from ''taking any action'' against student protesters barricading a campus building as long as the protest did not disrupt activities in the building. The judge, Justice Bruce Wright of State Supreme Court in Manhattan, also barred the university from ''taking police action against the students'' who are protesting the university's investments in companies doing business with South Africa. The order, which was served on a trustee of the university, Ann S. Sand, will remain in force until a hearing at 4 P.M. Monday. A university spokesman, Fred Knubel, said that the university would comply with ''a lawful order'' but that its lawyers had not yet reviewed the document.
