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.

본 연구에서는 자기지도 BP 신경회로망의 은닉노드상의 활성패턴을 음성패턴의 분산표현된 개념으로 설정하고, 이 분산개념을 T.Kohonen의 자율조직 신경회로망(SOFM)의 입력특징으로 하는 복합적 회로망을 제안한다. 이렇게 함으로써 통상의 BP 신경망의 교육에 관련된 어려움과 패턴정합기로 떨어지는 약점을 해소하는 동시에 의미있고 다양한 내부표현을 추출해 낼 수 있다는 강점을 활용할 수 있고, SOFM의 강력한 판단기능을 이용하여 보다 구조적이고 의미있는 개념맵의 배열을 얻을 수 있게 되었다. 결과적으로 전처리가 불필요하고 자기교육이 가능한 독자적인 인식시스템이 구성된다.

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)
