Although over 800 references to child and infant anthropometry are in the literature, most have limited validity and application to current populations. Functional measures required by industry and government for federal safety standards for design of dummies, child products, furniture, or protective devices such as restraint systems have either been incomplete, inadequate, or nonexistent. Some of the limitations influencing validity of existing data have been outlined for the potential user. As a start toward obtaining necessary functional anthropometric data, The University of Michigan is currently conducting a study sponsored by the U.S. Consumer Product Safety Commission to obtain valid nationwide measurements on a representative U.S. population from birth to age 12 years. In this study some 41 measurements, including many functional measures, as well as seated and supine whole-body centers of gravity, are being taken utilizing a new automated anthropometric minicomputer system.

APPLICATION of nuclear energy for civilian automotive uses has possibilities, these authors say. Nuclear power for automotive applications, they feel, is technically feasible now where size and weight are not prime considerations; where size and weight are major parameters, discoveries of new materials for construction of nuclear-power reactors must be made. New materials are needed for reactor fuels, heat extractants, neutron reflectors, reactor construction materials, controls, and radiation shields which must have unique nuclear properties in addition to conventional engineering properties. This paper presents nuclear automotive propulsion devices in terms of technologies now available. The necessary radiation-shielding mass and weight requirements are presented for an ideal point-source nuclear-heat-power engine.
