In this paper, we introduce the concept of fuzzy nano M open and fuzzy nano M closed mappings in fuzzy nano topological spaces. Also, we study about fuzzy nano M Homeomorphism, almost fuzzy nano M totally mappings, almost fuzzy nano M totally continuous mappings and super fuzzy nano M clopen continuous functions and their properties in fuzzy nano topological spaces. By using these mappings, we can able to extended the relation between normal spaces and regular spaces in fuzzy nano topological spaces.

In this paper, we propose a neural net system for speech recognition, which is composed of two neural networks. Firstly the self-supervised BP(Back Propagation) network generates the distributed concept corresponding to the activity pattern in the hidden units. And then the self-organizing neural network forms a concept map which directly displays the similarity relations between concepts. By doing the above, the difficulty in learning the conventional BP network is solved and the weak side of BP falling into a pattern matcher is gone, while the strong point of generating the various internal representations is used. And we have obtained the concept map which is more orderly than the Kohonen's SOFM. The proposed neural net system needs not any special preprocessing and has a self-learning ability.

We introduce a concept of a 'fuzzy' map between sets by modifying the concetp of the extension principle introduced by Dubois and Prade in [1] and by using this we generalize Goguen's and Zadeh's extension principles in [2] and [3].

Purpose: To determine the mediating as well as moderating effect on both the emotional labor and burnout of professional self-concept perspective organ transplantation coordinators (OTC)'. Method: A self-report questionnaire was collected from 86 OTCs nationwide. The data were analyzed using t-test, ANOVA, Scheffe' test, Pearson' Correlation Coefficients, AMOS 20.0, and multiple regression. Results: For effects of professional self-concept on emotional labor and burnout, higher emotional labor was related to higher burnout. When professional self-concept was mediated, emotional labor had a greater effect on burnout however, a partial mediating effect was detected. From the regression analysis with the independent variables of emotional labor (A) and professional self-concept (B), adding relation of both variables ($A{\times}B$) increased the explained variance to 56.3% ($p$<.05). It was confirmed that professional self-concept had a moderating effect on emotional labor and burnout. Conclusion: The results of this study indicate that, when professional self-concept was mediated emotional labor of an OTC decreased, and burnout decreased when professional self-concept was high. Also, by controlling professional self-concept, emotional labor and burnout decreased. Therefore, it's necessary to map out the environment and develop strategies to reduce emotional labor and burnout in organ transplantation coordinators.

In this paper, we introduce the concept of a weakly P-space which is a generalization of a P-space and prove that for any covering map f : $X{\rightarrow}Y$, X is a weakly P-space if and only if Y is a weakly P-space. Using these, we investigate the minimal basically disconnected cover of weakly P-spaces and their products.

This study is for finding out if using the method "Mind Map" in the section "function" during the math class affects on the disposition and solving problems of the students or not The study has found the following results: 1. The chains of concepts has formed by using both right brain and left brain in the students′ notebooks. 2. The power of math in the ability of solving problems has been strengthened.

In this paper, we introduce the concept of fuzzy m-sets induced by a given fuzzy supratopology and investigate general properties of the new class consisted of fuzzy m-sets. We also introduce notions of fuzzy m-continuity, fuzzy m-open(closed) maps and study some properties of them.

Orthoimage, digital map, cadastral map, and areas and district were converted and overlaid so as to apply legal restrictions on boundaries set by a land object concept restriction line and to analyze boundaries formed by overlaying areas and districts and characteristics of restrictions. With the restriction lines made on the basis of orthoimage.

A convergence structure defined by Kent [4] is a correspondence between the filters on a given set X and the subsets of X which specifies which filters converge to points of X. This concept is defined to include types of convergence which are more general than that defined by specifying a topology on X. Thus, a convergence structure may be regarded as a generalization of a topology. With a given convergence structure q on a set X, Kent [4] introduced associated convergence structures which are called a topological modification and a pretopological modification. (omitted)
