The supply of orthotist prosthetists. The application of workforce projection techniques in determining future national training places.

Discusses the application of workforce planning techniques in the context of "target" levels of demand and uses a study of the future supply of orthotists and prosthetists as an example. Describes the derivation of an appropriate model, the quantification of the labour market for the profession, and an analysis of the characteristics of the workforce. Information was gathered through two surveys and from discussions with relevant organizations.

Using early memories as a projective technique--the cognitive perceptual method.

This paper will present the cognitive-perceptual method of interpreting early memories together with the first published sequence interpretation of a set of early memories using this method. The latter is especially apt to present in this issue, considering Walter Ktopfer's stress on sequence interpretation of the Rorschach. Attention is also directed to the formation of a cross-disciplinary group that will investigate autobiographical memory in general and early memories in particular.

[Dose requirements for projection techniques in x-ray diagnosis].

The dose required in x-ray diagnosis depends upon the demands made on a diagnostically optimal x-ray film or in fluoroscopy, and upon the technical quality of the equipment. The actual dose requirement, derived from field studies, is juxtaposed on the basis of representative examples with the maximum permissible dose requirement in accordance with the prescribed minimum sensitivity values of the x-ray film. The ideal dose requirement has been stated by Cohen et al. (1981) by a formula basing on parallel beam, maximum quantum yield and Bucky grid effect depending on the signal to noise ratio and object contrast. This was checked by means of contrast detail diagrams measured at the hole phantom, and was additionally compared with measurement results obtained by Wust et al. (1989) with acrylic glass phantoms. The optimal dose requirement is obtained by the maximum technically possible approach to the ideal requirement level. Examples are given, besides for x-ray equipment with Gd2 O2 S screen film systems for grid screen mammography, and new thoracic examination systems for mass screenings. Finally, a few values concerning the dose requirement or the analogous time required for fluorescent screening in angiography and interventional radiology, are stated, as well as for dentistry and paediatric x-ray diagnostics.
