Quality control of science teachers seems to be one of the most important tasks to improve the quality of science education in Korea. The purposes of this study, as a survey, were to identify characteristics of good science teachers and to make an outline of preservice teacher education curriculum for cultivating the characteristics from inserivce secondary science teachers. A questionnaire was developed for this study and distributed to 176 inservice teachers. It had three parts: 1) characteristics of good science teachers, 2) weights of preservice curriclum areas, and 3) weights of college courses. The means and standard deviations of teachers' responses were calculated. To test the differences between teacher variables, t-tests were executed. The inservice teachers perceived that the junior-high school teacher's characteristics should be different from the senior-high school teacher's. Characteristics, such as enthusiasm toward teaching or students, subject knowledge, content selection and organizing skill, teaching techniques, and scientific worldview were ranked within top five of good science teacher's chracteristics. The teachers' perception about preservice curriculum were as follows: 1) present weight of liberal arts area should be reduced: 2) weight of content area for junior-high school teachers should be different from that for senior-high school teachers: 3) present weight of pedagogy area should be increased: 4) present weight of science education area should be increased: and 5) many courses in pedagogy and sciencd education areas need to be changed, Based on the data and disussion, a conceptual model for preservice teacher education curriculum was proposed.

The purpose of this study was to find out the nationwide general characteristics and housing environments of agricultural households and the differences of them by Eup-Myun Areas. The data were subsample of the 2008 survey on the rural living indicators collected by the rural development administration. Only agricultural households, 73.7% of the original nationwide data (1,461 households out of 1,983) sampled by multi-stage stratified clustering methods and face to face interview in Aug. 2008, were selected and the cross-tabulation(X2) was mainly used to find the difference by Eup Myun areas through spss 12.0 for window. The results showed that the general characteristics of agricultural households such as head of household, family, and economic characteristics were mainly differed by Eup Myun Areas. Agricultural households in Eup area were more likely low in the general characteristics than were those in Myun area. Housing environments were less likely than the general characteristics differed by Eup Myun areas. Improvements of drinking water system, housing alteration, oder, and garbage system were needed to increase the satisfaction with residential environments of agricultural households. This study suggests the use of annual survey on the rural living indicators data would be applicable to various research subjects of home economics.

In this paper, investigated are the machining characteristics such as material removal rate and machining time with respect to discharge area and capacitance in micro electrical discharge machining (MEDM). As discharge area determined by the electrode size and capacitance change, the optimal feedrate to allow the minimum machining time changes. The smaller discharge area is, the lower MRR becomes because of the area effect. As the capacitance increases, MRR also increases. However there is the limit capacitance beyond which the MRR does not increase anymore. As the discharge area increases, the limit capacitance also increases.

The purpose of this study was to establish the basic information for natural drainage capacity assessment in urban area. We sorted midium watershed of Han river and Nak-dong river, and selected 30 rainfall events during 1995 to 2000 according to high level of damage. The inundated area showed high watershed slope about 25% and it indicated the greatest damage around the watershed located in 200-300m of altitude. Besides, the great damage by inundation was occurred in the mountainous agriculture region, where the forest scale was high and the urbanization was being progressed gradually. However, inundated area was small in case of grassland, water tone such as riparian area, bare ground and wetland. Moreover, the inundated area was different according to river shape and characteristics of river distribution such as the density of the stream order, conservation constant of the river system, and the number of undulations in the watershed. Therefore, it showed that land use, river shape and distribution characteristics of stream influence on inundation.
