In order to investigate the effects of environmental scientific education on high school students' environmental knowledge, behavior, and practice, this study selected the test group of two schools that enforce environmental scientific education and the control group of two schools that do not enforce it. These are the results of the comparison between two groups. 1. The comparison of the average mark on the environmental knowledge, behavior, practice between two groups showed following results. In regard to the knowledge, the mark of the test group was higher than that of the control group. (p<0.001) and as for the behavior, the point of the test group was also higher than the control group(p<0.05). With respect to the practice, two groups made little difference. 2. The factor that had most greatest influence on the environmental knowledge was the students' school achievements(R2=15.0%), and in turn, the environmental instructions and the degree of consciousness on the necessity of environmental preservation were the important factors. In regard to the behavior, the degree of consciousness on the necessity of environmental preservation was the most important factor(22.1% of reliability), and in turn, the degree of concern on the environmental problems, the school achievements, and the proportions of parents' environmental preservation practice were important. The coefficient of reliability was 29.1%. As for the practice, the most far-reaching factor was the extent of the students' concern on the environmental problems(19.3% of reliability). and the proportions of parents' environmental preservation practice, the degree of the consciousness on the necessity of environmental preservation, the level of the economic conditions, the extent of parents' concern on the environmental problems were important in turn. The coefficient of reliability on the practice were 30.2%.

김형갑,서현효 진주산업대학교 환경문제연구소 1998 環境硏究論文集 Vol.1 No.-

A strain (designated SK31) which produces an excellent adsorption substance was isolated from soil samples and identified as Bacillus species. The major adsorption substance (biosorbent SK31) produced by Bacillus sp. SK31 was purified by ethanol precipitation and cetylpyridinium (CPC) precipitation. The adsorption charactics of zinc and lead ions on bioadsorbent SK31 were investigated. The equilibrium isotherms showed that bioadsorbent SK31 took up zinc and lead from aqueous solutions to the extent of about 52㎎/g and 112㎎/g, respectively. The culture conditions at the flask level of Bacillus sp. SK31 were investigated for the production of polysaccharide bioadsorbent, SK31. The optimum pH and temperature for sorbent production were 7.5 and 30℃, respectively. The important substrates for sorbent formation were glucose and ammonium nitrate. In the optimized medium, sorbent production was improved three folds in comparison with the basal medium. In the jar fermenter, the highest sorbent production was obtained at 60 h cultivation time and the amount of biosorbent SK31 at that time was 8.2g/1.

김형갑,김명종 진주산업대학교 산업과학기술연구소 2007 산업과학기술연구소보 Vol.- No.14

The samples of 31 vegetable items, showing the high average intake per day in the 2001 National Health and Nutrition Report(Ministry of Health and Welfare), were selected from the 4 areas in Jinju - Jayu Market, Joong-ang Market, Chunjun Market, and E Mart. Among them, the heavy metal uptakes by the 8 items, i.e. Chinese cabbage, lettuce, leek, dropwort, radish, onion, and red pepper were analyzed, utilizing Inductively Coupled Plasma Spectrometer(ICP). The following are the results of Hg, Cd, Pb, As, Zn, Cu, Mn, Cr, Fe content analysis of the samples. 1. The minimum, maximum, and average level of the respective heavy metal content [mini.~maxi.(mean)]ppm(mg/kg) was as follows. Hg: ND~0.014(0.001), Cd: ND~0.024(0.003), Pb: ND~0.980(0.187), As: ND~0.322(0.097), Zn: 0.335~5.386(1.257), Cu: 0.276~1.598(0.675), Mn: 0.278~12.543(2.433), Cr: ND~0.629(0.053), Fe: ND~6.103(1.793) 2. Compared with the permissible limit, the average heavy metal content detected from each area showed that the level of Mn was somewhat higher than the limit while that of Pb was close to the limit. The levels of the rest of the heavy metals were lower than the limit. The detected amount of the heavy metals followed the order of Mn>Fe>Zn>Cu> As>Pb. 3. Even if this study was conducted in a limited area within a short period of time, each area did not show a noticeably different result, reflecting the fact that in terms of heavy metal concentration, there is no significant environmental difference between the general agricultural area and the organic agricultural area. The heavy metal concentrations of the vegetables circulated in Jinju were within the safe limit regulated by the WHO/FAO.
