The Missouri Automated Radiology System recently passed its tenth year of clinical operation at the University of Missouri. This article presents the views of a radiologist who has been instrumental in the conceptual development and administrative support of MARS for most of this period, an economist who evaluated MARS from 1972 to 1974 as part of her doctoral dissertation, and a computer scientist who has worked for two years in the development of a Standard MUMPS version of MARS. The first section provides a historical perspective. The second deals with economic considerations of the present MARS system, and suggests those improvements which offer the greatest economic benefits. The final section discusses the new approaches employed in the latest version of MARS, as well as areas for further application in the overall radiology and hospital environment. A complete bibliography on MARS is provided for further reading.

Discussions about the role of small enterprise in economic development tend to remain inconclusive partly because of the difficulty of assessing the relative importance of economic and non-economic objectives and partly because of the dearth of factual information on which to base an economic calculus. It is probably true, moreover, that, because of a lack of general agreement as to the economic case for or against small enterprise, non-economic considerations, including some merely romantic attitudes toward smallness and bigness, tend to exert an undue influence on public policies. There may, of course, be no clear-cut economic case. And noneconomic considerations should and will inevitably weigh significantly in policy decisions. If, however, some of the economic questions could be settled by more and better knowledge, these decisions could more accurately reflect the opportunity costs of pursuing non-economic objectives.

UK research into the beneficial uses of dredged material is being undertaken at Strathclyde University, and includes initiatives in research in the use of dredgings for soil in land restoration projects, and for brick manufacture. Extensive research in the historically industrial River Clyde in Scotland has shown that pollutant levels do not preclude the use of selected materials for land restoration work. However, limitations are imposed on the use of the material for agricultural or grazing purposes at this time. Brick manufacture from clay sediments has proved that an attractive, quality product can be provided to the industry although some further testing is required; particularly in the area of atmospheric emissions during firing. The use of dredged clay for landfill capping and lining also remains a viable possibility. Economic considerations for each application vary, and require further investigation, however, the options are technically feasible and if employed on a larger scale, can account for a significant proportion of dredged sediments which are currently disposed of at sea.
