Subjects were 151 early childhood teachers in Seoul and Chungcheungnam-do. The collected data were analyzed using simple regression, hierarchical multiple regression and the Sobel test. The main results of this study were as follows. First, teachers' playfulness and teachers'positive play beliefs had a positive influence on their proactive, positive reactive strategies of problem behaviors. On the other hand, teachers' positive play beliefs had a negative influence on their negative reactive strategies of problem behaviors.

PMT(Preventive Maintenance Template) is a standardized maintenance program that describes maintenance items & period as operation condition to increase component reliability at the component level. The existing maintenance programs are focused on time based maintenance to inspect and repair component depend on fixed period. But recently, we have developed advanced maintenance program(named PMT) to increase reliability and optimize maintenance program of the plant significant component. This paper presents how to develop the PMT for nuclear power plant's static exciter.
