TL;DR: In this article, psycho-social training was applied to a group of TEFL students (experimental group) combined with intensive English pronunciation training (Experimental and control groups) and the results of the statistical analysis showed that the levels of pronunciation anxiety and pronunciation quality were similar in both groups before the training.

TL;DR: An analogy of the Kolmogorov–Sinai Theorem on generators is proved for fuzzy dynamical systems because it is shown that different definitions of the entropy of fuzzy partitions lead to different notions of entropies of fuzzy dynamicals systems.
Abstract: In the paper we define three kinds of entropy of a fuzzy dynamical system using different entropies of fuzzy partitions. It is shown that different definitions of the entropy of fuzzy partitions lead to different notions of entropies of fuzzy dynamical systems. The relationships between these entropies are studied and connections with the classical case are mentioned as well. Finally, an analogy of the Kolmogorov–Sinai Theorem on generators is proved for fuzzy dynamical systems.

TL;DR: The first aim of this study is to define soft topological spaces and to definesoft continuity of soft mappings, and to introduce soft product topology and study properties of soft projection mappings.
Abstract: The first aim of this study is to define soft topological spaces and to define soft continuity of soft mappings. Second is to introduce soft product topology and study properties of soft projection mappings. Third is to define soft compactness and generalize Alexander subbase theorem and Tychonoff theorem to the soft topological spaces.

TL;DR: In this paper, the concept of fuzzy soft group is introduced and in the meantime, some of their properties and structural characteristics are discussed and studied, including fuzzy soft function and fuzzy soft homomorphism.
Abstract: In this paper, the concept of fuzzy soft group is introduced and in the meantime, some of their properties and structural characteristics are discussed and studied. Furthermore, definitions of fuzzy soft function and fuzzy soft homomorphism are defined and the theorems of homomorphic image and homomorphic pre-image are given. After that, the definition of normal fuzzy soft group is given and some of its basic properties are studied.

TL;DR: In this paper, a generalization of the model expounded in the previous chapter is presented. But the model is restricted to the family of all measurable functions f: (Ω, ℒ) → [0, 1] with two binary operations (denote them by ⊕ and ⊙), a unary operation * and two fixed elements 0 Ω, 1Ω where ==================>>\s.
Abstract: In this chapter we shall study a generalization of the model expounded in the previous chapter. We introduced a basic example, at the beginning of Section 8.1. We considered there the family of all measurable functions f: (Ω, ℒ) → [0, 1] with two binary operations (denote them by ⊕ and ⊙), a unary operation * and two fixed elements 0Ω, 1Ω where
$$ f \oplus g = (f + g) \wedge 1$$
$$ f \odot g = (f + g - 1) \vee 0$$
$${f^*} = 1 - f]$$
