continued A British hospital has come up with new hope for women likely to miscarry or suffer stillbirths. Using a "fully automated fetal monitoring machine," doctors at Rochford Hospital in Essez recently delivered Mrs. Marie O 1 Donovan of a healthy son after three previous stillbirths and one miscarriage. The monitoring machine, devised by Rochford technician Dennis Richards, permits rapid and repeated testing of the mother's oestriol hormone level, the best barometer of the baby's safety in the womb. Normally, as a pregnancy progresses, the level of oestriol found in the mother's urine increases; conversely, a drop in the level signals danger to the fetus of suffocation or starvation. Formerly, laboratory examination of the mother's oestriol level was a complicated and time-consuming procedure which could not be performed frequently enough to provide an adequate barometer of progress. The Rochford machine, however, can complete as many as 100 tests a day. In the case of Mrs. 0'Donovan, three weeks before her baby was due the machine sounded the alarm. Alerted to the danger of stillbirth, doctors successfully delivered 5 Ib. 3 oz. Mannix 0'Dono- van by Caesarean section. Locarte, a London manufacturer, will have the Rochford machine ready for delivery to other hospitals by the end of the summer. Kodak has obtained the approval of the Malaysian government to construct a film and camera factory in Kuala Lumpur. Two years ago, to meet the lower Japanese labor costs, German camera companies began to manufacture their products in Singapore. Thousands of famed Rollei- fl exes now come from there instead of Braunschweig, Germany. In the 1948 Presidential election, public opinion polls predicted certain victory for Republican candidate Thomas E. Dewey. Confident of winning, Dewey campaigned coolly and cautiously-and lost to fighting Harry Truman. Since then, the art of polling has become far more sophisticated. But still-can you trust the polls? The Opinion Research Corporation of Princeton, N.J., suggests you ask the following key questions to evaluate the results of public opinion polls: 1. Who was interviewed? Were the people interviewed representative of all adults in the U.S.? Only those registered to vote? Republicans, or Democrats? Differences between polls may reflect the fact that different kinds of people were interviewed. 2. How many people were interviewed? The reliability of a poll depends on how many people were interviewed. As a general rule, the larger the number of people interviewed, the greater the accuracy of the poll. 1. How were the people to be- interviewed selected? For the most accurate results, those interviewed should be selected by statistical probability methods. 4. How were the interviews conducted? Polls are usually conducted by telephone, personal in-home interviews or by self-administered questionnaires. Most reliable is the personal interview. 5. When was the poll conducted? A poll indicates the strength of a political candidate at a particular point in time. If time has elapsed between polling and publication, the results may be misleading and even obsolete. 4. How were the questions worded? Comparing the results of two or more polls, carefully examine the wording of the questions. Unclear, biased, or emotionally- charged questions may produce misleading answers. 7. Who conducted the poll? Past reputation is not always a guarantee of future reliability, but some pollsters have better track-records than others. Be aware of the difference. 0. Were any special analytical or statistical procedures used? Most polls report their findings in three categories: pro, con, and undecided. If the last category is omitted, be aware that the undecided vote may be split among the candidates or weighed unevenly in favor of one of them. AS Â«E * CNSIU. MK SUN4EEKERS JUK THRONCHM TO There are package holidays for students, doctors, singles, architects. Why not nudists? Well, there are, and they're for sale in Germany, which counts an estimated 1 million nudists. European countries which are willing to accommodate nude sunbathers this summer, providing the nudists remain within specified enclaves, are Germany, Yugoslavia, France, Italy, Sweden, and Corsica. It sounds incredible but it is true. In the United States, which boasts the world's highest standard of living, there are 3 million adults who are totally unable to read and write and another 20 million, according to U.S. Office of Education estimates, who read so poorly that they are classified "functional illiterates." By contrast, the Soviet Union has an illiteracy rate of only 2 percent; Japan 1-2 percent; France 0-3 percent, Sweden none. Marushin Company, a Tokyo hamburger maker, has developed what it terms "the world's first hamburger vending machine, the Macburger." The Macburger stocks 90 packaged hamburgers in its refrigerator. When a coin (the equivalent of 33 cents) is inserted, a packaged hamburger is ejected after being automatically heated for one minute in an electronic oven inside the machine.
