age 8-Wednesday, March 25, 1981 -The Michigan Daily Polish labor union calls for more protest strikes From UPI and AP BYDGOSZCZ, Poland - Angered by police beatings, the Solidarity labor union voted yesterday to call two protest strikes that Communist Party chief Stanislaw Kania said could lead to "catastrophe" and "self-destruction." Solidarity officials said a four-hour warning strike would be held on Friday, followed by a one-day general strike next Tuesday to protest a police assault on union officals in the northwestern city of Bydgoszcz last week. KANIA SAID Solidarity's call for strikes "cannot be interpreted other- wise than a call for self-annihilation." Three persons were hospitalized following the attack that thrust the nation into its -worst labor crisis since the summer strikes that spawned Poland's independent labor movement. Solidarity, whose leadership met through the night yesterday, said the strikes could be called off if the gover- nment and the union reached agreement before Friday on a set of new demands stemming from the Bydgoszcz incident. A meeting betwen high-level officials from both sides was scheduled for today. THE CALL FOR A general strike revived fears of possible Soviet inter- vention to crush the independent union movement, and military maneuvers by Warsaw Pact nations continued in Poland and its neighbors. In the Netherlands, a summit con- ference of the European Common Market warned against any interven- tion. A closing declaration issued at the conference in Maastricht said Poland "has shown that she is capable of facing her internal problems herself" and "should continue to do so in a peaceful manner and without outside interferen- ce. It is also in the interest of stability in Europe." Solidarity leader Lech Walesa, still regarded as a national hero for his role in the August strikes, prevailed over pro-strike militants and came out with a compromise to stage brief warning strikes. "THIS IS NO TIME for quarrels because we can lose," Walesa told his fellow Solidarity leaders. "Rumors have reached me that a state of emergency could be introduced by the government tomorrow," he said. "The question is whether or not we can avoid full-scale confrontation." "IT MUST BE A strong blow. Cities must look as if it were a national funeral," one Solidarity official said. Over the weekend, Warsaw television showed footage of East bloc troops on maneuver in southern Poland and other Soviet bloc countries, apparently to remind Solidarity that the Kremlin is capable of intervening. .:.: x" ^:r._. ..max..,.;; ..; ..::::::n"::...:: .>;r +t "ssr :: :. .:: .p :::::: ... .. .::::... :<"airir-::::::: ::::. :.; :::. r::::::: :::. :::.::::. ::. :. __ .. .... .".

Waterbeds to aid premature infants' incubation CHICAGO (AP)-A company is donating 200 tiny waterbeds to Chicago- area hospitals after doctors found that premature babies who lie on waterbeds in their incubators grow fasted and ex- perience fewer breathing and heart problems. Warm and gently rocking, the heated incubator waterbeds also simulate the floating environment of the mother's womb. Dr. Henry Mangurten, director of the newborn intensive-care unit at Lutheran General Hospital in Park Ridge, is enthusiastic about incubator waterbeds for high-risk infants. He has been experimenting with a dozen waterbeds in his 30-incubator unit for two months and plans a more detailed ' study. "We've found that the beds help premature babies with irregular breathing and heartbeats," Mangurten said. "The incidence of these episodes goes down significantly-they are fewer and less severe."~ He said waterbeds also keep pressure off critical joints that stick out in infan- ts born eight to 12 weeks prematurely. Lutheran General is among 24 hospitals in the area that will get 200 in- cubator waterbeds from Peppers Waterbeds.
