Fibre Modification

The publication presents investigation results and statistical analysis showing that by varying the chemical structure of optical brighteners from the derivative group of stilbene used for fabrics of artificial cellulose fibre modification, resulting in a different manufacturing process, it is possible to predict the level of the UPF value of the index of such modified fabric. In addition, statistically it was confirmed by results from early research that both the fibre finish (in this case, roughening the pigment TiO2 ) used for fabric manufacture as well as the FBA concentration used for fabric modification influence their UPF index value. Fabric UV -barrier studies also showed that despite a partial decrease in UPF values for such finished fabrics, the dependence of such an index on subtle differences in the chemical structure of the FBAs is maintained. Primarily the possibility and range of improving textile barriers against UV radiation through the use of the UV-absorption abilities of optical brighteners with subtle differences in their chemical structure was recognised, creating a premise to elaborate a mathematical control concept to steer a textile UV-barrier.

Process View

Summary Objectives: Many shared-care projects feel the need for electronic patient-record (EPR) systems. In absence of practical experiences from paper record keeping, a theoretical model is the only reference for the design of these systems. In this article, we review existing models of individual clinical practice and integrate their useful elements. We then present a generic model of clinical practice that is applicable to both individual and collaborative clinical practice. Methods: We followed the principles of the conversation-for-action theory and the DEMO method. According to these principles, information can only be generated by a conversation between two actors. An actor is a role that can be played by one or more human subjects, so the model does not distinguish between inter-individual and intra-individual conversations. Results: Clinical practice has been divided into four actors: service provider, problem solver, coordinator, and worker. Each actor represents a level of clinical responsibility. Any information in the patient record is the result of a conversation between two of these actors. Connecting different conversations to one another can create a process view with meta-information about the rationale of clinical practice. Such process view can be implemented as an extension to the EPR. Conclusions: The model has the potential to cover all professional activities, but needs to be further validated. The model can serve as a theoretical basis for the design of EPR-systems for shared care, but a successful EPR-system needs more than just a theoretical model.
