Alsina Català, Claudi; Trillas i Gay, Enric; Moraga, Claudio
Using techniques for modeling indices by means of functional equations and resources from fuzzy set theory, the classical Balthazard index used in order to combine several degrees of impairment is characterized in two natural ways and its use is criticized. In addition some hints are given on how to study better solutions than Balthazard's one for the problem of com-bining impairment's degrees.

Gallego Lupiañez, F.
The basic concepts of the theory of intuitionistic fuzzy topological spaces have been defined by D. Çcoker and co-workers. In this paper, we define new notions of Hausdorffness in the intuitionistic fuzzy sense, and obtain some new properties, in particular on convergence.

Ovchinnikov, Sergei V.; Falmagne, Jean-Claude
We establish a necessary and suficient condition for a function defined on a subset of an algebra of sets to be extendable to a positive additive function on the algebra. It is also shown that this condition is necessary and sufficient for a regular function defined on a regular subset of the Borel algebra of subsets of a given compact Hausdorff space to be extendable to a measure.
