  • In this study, a shaking table test was performed for the evaluation of water extinguishing facilities. Water extinguishing facilities, such as a general pipe, a seismic pipe (Loof type) and a pump, were used in the experiment. This captured the dynamic characteristics of water extinguishing systems by earthquake records at El-Centro with a 50%, 70%, 100%, 120% level. As a result, seismic type facilities have excellent seismic performance compared to general facilities. By using the acceleration response spectrum, not only is the performance evaluation of water extinguishing facilities able to be determined, but also the deformation of facilities in low earthquake levels can be known. This proposed approach can determine the seismic performance evaluation of water extinguishing facilities and verify seismic performance criteria.

  • The purpose of this study was to analyze and determine the level of the satisfaction and awareness of facilities in child care centers among teachers and parents. Special attention was given to both the indoor and outdoor environments from the viewpoints of both parents and teachers. The subject of this research focused on parents who leave their children at child care centers, and teachers who work for the center. The data was compiled by performing both T-tests and paired T-test. The information was processed by a program called SPSS WIN 10.0. The results were as follows ; 1. (a) With regard to the satisfaction of the external and internal facilities : It was determined that both the play rooms and the wall-pattern arrangements were satisfactory to both the parents and the teachers. (b) Regarding the awareness of the importance of facilities, while the parents focused more on the play rooms and the external environments, the teachers placed more importance on the bathrooms and the play rooms. 2. In the paired T-test that determined whether their individual opinions were different in terms of the satisfaction and awareness of facilities, it was interesting to see that both the parents and the teachers showed significant differences in their opinions and priorities about the porches, the play rooms, the bathrooms and the wall-pattern arrangements. In general, their awareness was much higher than the satisfaction with these facilities. 3. In the T-test that determined whether there were any tendencies in the satisfaction and awareness respectively in the two groups, the satisfaction rate was higher among the parents than the teachers. In terms of the awareness of the importance of the facilities, the teachers rated the bathrooms and the wall-pattern arrangements as a priority.
