'I _ blliational Research Council :. _ i; f PROPERTY OF NATIONAL ACADEMY PRESS Washington, D.C. 1990 NOTICE: The project that ia the subject of thia report was approved by the Goveming Board of the National Research Council, whose members are drawn from the councila of the National Academy of Sciences. the National Academy of Engineering, and the Institute of Medicine. The memben of the commiuee reaponaible for the report were chosen for their special cornpetencc: and with regard for appropriate balance. This report hu been reviewed by a group other than the authors according to procedures approved by a Report Review Committee consisting of members of the National Academy of Sciences, the National Academy of Engineering. end the Institute of Medicine. The National Academy of Science: is a private, nonprofit, self-pexpetuating society of distinguixhed scholln engaged in tdentific Ind engineering research, dedicated to the funhennee of science and technology and to their use for the general welfare. Upon the authority of the chaner granted m it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal govemment on scientific and technical matters. Dr. Frank Press ia preaidcm of the National Academy of Sciences. The National Academy of Engineering was eztzblished in 1964. under the charter of the National Academy of Sciences. a: l penllel organization of outstanding engineer-s. It is autonomous in its administration and in the selection of its members, shuing with the National Academy of Sciences the responsibility for ndvising the federal govemment. The National Academy of Engineering also sponsor: engineering programs aimed at meeting national needs, encoumges education and research, and recognize: the iuperior achievement: of engineers. Dr. Robert M. White ia president of the National Academy of Engineering. The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters penaining to the health of the public. 'lhe Institute acts under the responsibility given to the National Academy of Sciences by ita congressioml chanel' to be an adviser to the federal government and, upon its own initiative. to identify issues of medical care, research, and education. Dr. Samuel O. 'Haier i: president of the Institute of Medicine. The National Research Council was established by lhe Nationnl Academy of Science: in 1916 to associale the broad community of science and technology with the Academy's purposes of funhering knowledge and of advising the federal government. Functioning in accordance with general policies determined by the Academy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineering communities. The Council is adminiuered jointly by both Academics and the Institute of Medicine. Dr. Frank Press and Dr. Robert M. White are chairman and vice-chainnan. respectively, of the National Research Council.
