Abstract: A process for the formation of a patterned resist image upon a substrate comprises the steps of: (i) mechanically applying a layer of a suspension of a powdered solid photocurable material in a liquid carrier to the substrate; (ii) drying the resultant layer by evaporation of the liquid carrier and reflowing the powder, under the action of heat, to give a coherent film; (iii) imagewise exposing the dried film to radiation through a patterned mask whereby portions of the film exposed to radiation are cured; and (iv) subsequently developing the exposed film by removing unexposed portions thereof with an appropriate solvent.

Abstract: A system and process are presented in which the factors of quality, cost, and access are integrated in such a manner as to provide a holistic description of the effectiveness of care at medical treatment facilities (MTFs). By using medical treatment data from a variety of computerized databases and incorporating patient perceptions of care through the use of surveys, the effectiveness of a particular facility's medical care can be compared to other medical care facilities. Deficiencies in performance are readily identified through this process, permitting goals and targets to be established that provide direction for medical administrators to enhance medical care at their treatment facilities. This approach is applicable to any set of medical care facilities, and also to just about any organized human endeavor involving quality, cost and access factors.
