This research aims to take a close look at the following topics; the ground elevation of playground, equipments of playground, and equipments around playground, and to propose the improvement measure for favorable educational environment. In consideration of the needs mentioned, the following improvement measure for playground can be suggested. First, the elevation of playground should be changed. According to Environment psychology, current playground elevation should be lowered 2 stair-long height from a classroom site. This kind of elevation change can remove unnecessary stairs, and reduces inconvenience incurred by stairs and edges, which results in considerable educational finance saving. Second, the incidental equipment within a playground needs to be improved. This fact is found out at the surveyed schools; school gathering is held at classrooms (through broadcasting) or a multi-purpose auditorium in place of a playground. The results of this study make us conclude that the most important issue to be considered in the processes of selection and investigation for school playground elevation, incidental equipments and others.

This work investigated the performance improvement of a medium-pressure fixed-displacement-type SPUR gear pump, which is mainly used in the machine tool industry. The 3D CFX analysis and IS technique were applied using ANSYS (commercial FEM code) and compared with experimental results to ensure the reliability of the analysis. In addition, the performance improvement of the pump was obtained using the theoretical volumetric displacement equation, and the gear tooth width was changed. The pressure flow performance curves were compared, and the results were analyzed according to the width of the gear teeth. This is a factor that can cause irregular flow, vibration, and noise inside the gear pump owing to friction between the housing and gear pump.

The purpose of this study was to examine the effect of peer mentoring activity in elementary school. For this study, an experimental group was conducted for peer mentoring activity in science class. The mentoring team was organized by mento-mentee team according to the scores of science process skill and achievement. The objects of this study were the sixth grade of both an experimental group (28 students) and a control group (27 students) located in Incheon. The results of this study were as follows. First, the experimental group was shown more significant effect for improvement of science process skills than the control group (p<.05). As the result of analysis by groups, both of mento and mentee showed significant effect for improvement of science process skills. Second, the peer mentoring activity showed more significant effect for improvement of achievement (p<.05). As the result of analysis by groups, mentee showed significant effect for improvement achievement. But mento group didn't show significant effect. Third, the peer mentoring activity showed the effect for positive changes of scientific attitude. If matching the mentoring object effectively and conducting the classes applying peer mentoring activity based on the results of this study, it's expected to draw student' improvement of science academic, achievement and positive changes of scientific attitude.

This study is to explore effective implementation strategies of elective-based curriculum in high schools, and to infer some implications for the improvement of school facilities. For the purpose, this study did three things. First, it tried to find the degree to which students are provided with the courses they want to take for the elective-based curriculum. Second, it explored effective implementation strategies of elective-based curriculum in high schools with the introduction of students' 'pre-application and lottery-allotted system' of high school admission. Third, it tried to infer the changed policy's implications for the improvement of school facilities. As a result of the study, three points are to be emphasized for the future plan and design of high school facilities. First, different school facilities are needed for each school because each school would implement different types of school curricula. Second, schools should be provided with different sized classrooms and different number of classrooms because three different types of students are assigned for each school as a result of new students' allocation policy. Third, new measures should be taken to provide students who are assigned to unwanted schools with opportunities to take courses outside their schools because students assigned by lottery system cannot have so much opportunity as students who are allocated to chosen schools.
