The purpose of this study was to investigate about current status of science field study in elementary schools. A total of 72 elementary teachers in Busan and Gyungnam districts were involved and the data from questionnaire was gathered. The questionnaire was comprised two parts: items on general level include the epistemological aspect and actual condition and items on concrete level according to chapters of elementary school science curriculum. The major findings are as follows: 1. Many teachers cognize the requirement of science field study in 7th Korean elementary school science curriculum is larger than 6th one. But they respond the actual number of science field study in 7th curriculum is nearly equal to 6th. 2. In analysis to grades, the actual number of field study decrease as grade is high. 3. In the science content aspects, the requirement of field study is the largest on biology domain and earth science domain. 4. Many teachers have pointed out “the difficulty of administration for field study” and “inappropriated surrounding of their school” as the problems of science field study in elementary school.

In spite of the benefits of field studies, field surveys have not well performed in secondary school. Although many field sites have been developed lately, most field guidebooks describe the geological formations at the outcrops professionally so they can not be used by secondary school students. It is necessary to develop the field study program with which earth science teachers can do field activities easily rather than the one of a highly technical nature. The purpose of this study is to develope a secondary school geology course and to help earth science teachers practice it by providing the efficient teaching methods for the field study

This study was conducted to identify the road effect on small rodent populations within fragmented forest areas around the road from June to September 2002, in 9 study sites of Baekdugdaegan mountains, Korea. Two species of small rodents, Korean field mouse Apodemus peninsulae and striped field mouse Apodemus agrarius, were captured in this study. Korean field mouse preferred forest area, and striped field mouse generally has been found edge area around road. Mean body weight of Korean field mouse was significantly different, but that of striped field mouse was not between both distance from road. Korean field mouse is forest-dwelling species and their distribution is limited in forest area. In contrast, striped field mouse has wide distributional range around road. The effects of road is different in each small rodent species and their habitat preferences.

A former study has shown that the spin-lattice relaxation time ($T_1$) in cancerous prostate tissue had enhanced contrast at an ultra-low magnetic field, $132{\mu}T$. To study the field dependence and the origin of the contrast we measured $T_1$ in pairs of ex-vivo prostate tissues at the Earth's magnetic field. A portable and coil-based nuclear magnetic resonance (NMR) system was adopted for $T_1$ measurements at $40{\mu}T$. The $T_1$ contrast, ${\delta}=1-T_1$ (more cancer)/$T_1$(less cancer), was calculated from each pair. Additionally, we performed pathological examinations such as Gleason's score, cell proliferation index, and micro-vessel density (MVD), to quantify correlations between the pathological parameters and $T_1$ of the cancerous prostate tissues.
