Enhanced Bioslurping system을 이용한 유류오염 토양의 복원

김대은,서승원,김민경,공성호,Kim Dae-Eun,Seo Seung-Won,Kim Min-Kyoung,Kong Sung-Ho 한국지하수토양환경학회 2005 지하수토양환경 Vol.10 No.2

토양의 유류오염복원에 가장 널리 사용되어지는 Bioslurping system은 Pump and Treatment (P&T), Soil Vapor Extraction (SVE), 그리고 Bioventing (BV) 공정을 복합한 지중(in-situ) 복원기술이라 할 수 있다 그러나 Bioslurping system은 비휘발성 유기물질, 난분해성 유기물질을 처리에 어려움을 가지고 있어 이를 보완할 수 있는 Modified Fenton 반응을 이용한 Hybrid process system의 동시처리 가능성을 실험하였다. 디젤로 오염된 사질토양복 원에 있어서 SVE 공정에 의한 복원과정에서 디젤 제거율이 진공압에 비례하여 증가하였으나 토양에 강하게 흡착된 디젤 성분중의 비휘발성 물질처리에는 한계가 있음을 나타내었다. 또한 지표면과 지하에서 제거 효율의 차이를 나타냄으로서 지표면 또는 추출정과 거리가 멀어질수록 SVE 공정의 효율이 감소하는 것을 확인하였으며 이는 원통형반 응기에서 공기의 흐름이 반구형태로 유도되는 것에 기인한다고 판단된다. Modified Fenton 반응과의 생물학적 화학적 Co-oxidation을 이용한 디젤의 처리의 경우에는 Modified Fenton 반응의 효율이 낮게 나타나 0.1% (wt) 과산화수소가 존재함에 있어서도 92.8%의 높은 디젤분해능을 나타냄으로서 과산화수소가 유류분해 미생물에 산소원으로 사용될 수 있는 것은 확인하였으나 Co-oxidation의 가능성이 현저하게 떨어지는 것으로 보인다. Modified Fenton 반응에서 철 착체물로서 NTA를 사용했을 때가 EDTA를 사용했을 때보다 더 높은 효율을 갖는 것과 괴산화수소의 농도가 높아지면서 Modified Fenton 반응의 효율도 증가하는 것을 확인하였다. 대표적인 방향족, 지방족 화합물 (aromatic, aliphatic compound)인 toluene, hexadecane을 오염원으로 한 Modified Fenton 반응에서 상대적으로 지방 족 화합물의 상대적 안정성으로 인하여 그 효율이 방향족 화합물에 비해 크게 감소하는 것으로 나타났다. 또한 디젤을 오염물로 사용하였을 경우, 최소 10% 이상의 과산화수소에서 그 효율을 나타내어 Bioslurping system에 의한 처리 후 토양에 잔존하는 디젤의 Modified Fenton 반응 공정을 이용한 복원기술의 복합화 가능성을 확인하였다. Bioslurping combines the three remedial approaches of bioventing, vacuum-enhanced free-product recovery, and soil vapor extraction. Bioslurping is less effective in tight (low-permeability) soils. The greatest limitation to air permeability is excessive soil moisture. Optimum soil moisture is very soil-specific. Too much moisture can reduce air permeability of the soil and decrease its oxygen transfer capability. Too little moisture will inhibit microbial activity. So Modified Fenton reaction as chemical treatment which can overcome the weakness of Bioslurping was experimented for simultaneous treatment. Although the diesel removal efficiency of SVE process increased in proportion to applied vacuum pressure, SVE process was difficulty to remediation quickly semi- or non-volatile compounds absorbed soil strongly. And SVE process had variation of efficiency with distance from the extraction well and depth a air flow form of hemisphere centering around the well. Below 0.1 % hydrogen peroxide shows the potential of using hydrogen peroxide as oxygen source but the co-oxidation of chemical and biological treatment was impossible because of the low efficiency of Modified Fenton reaction at 0.1 % (wt) hydrogen peroxide. NTA was more efficiency than EDTA as chelating agent and diesel removal efficiency of Modified Fenton reaction increased in proportion to hydrogen peroxide concentration. Hexadecane as typical aliphatic compound was removed less than Toluene as aromatic compound because of its structural stability in Modified Fenton reaction. What minimum 10% hydrogen peroxide concentration has good remediation efficiency of diesel contaminated groundwater may show the potential use of Modified Fenton reaction after bioslurping treatment.

잣나무 차대검정에 (次代檢定) 있어서의 효율적인 Plot Sampling 에 관한 연구

김대은(Dae Eun Kim),전상근(Sang Keun Chon) 한국산림과학회 1991 한국산림과학회지 Vol.80 No.4

Tree height at age 10 was used to estimate the statistical efficiencies of sampling size in the progeny test of Pines korcriensis S.et Z. Experimental design was RCB design which consists of 25 half-sib families in each of three blocks. The number of families and blocks were fixed, therefore, the number of trees sampled per plot was the only factor that influences the environmental portion of the family mean height. Coefficient of variation, the estimate of the standard error of the family mean height, decreased with increase of sampling plot size, and became stable from 4-tree plot sampling (6.97%). The experimental error was significant from 7-tree sampling plot size. Nonlinear relationship (Y^=10.425e-^(0.073x) ; R²=0.840) was found between the sampling plot size and the standard error of family mean height.

Purpose: The purpose of this study is to investigate the effect of eight weeks of regular aerobic exercise on body composition and resting metabolic rate in obese women in their 20’s & 30’s and obese women in their 50’s & 60’s who have entered menopause. Method: In this study, the tested subjects were obese women residing in the city of S with a BMI of 25 or higher, or a body fat percentage of 32% or higher. They were separated into two age groups: women in their 20’s and 30’s (E1), and women in their 50’s and 60’s (E2). 16 subjects were selected with 8 subjects in exercise group 1 (E1) and 8 subjects in exercise group 2 (E2). The 8-week aerobic training consisted of moderate-intensity exercise at 55-65% THR. Exercise during weeks 1-4 were performed at 55-60% intensity, and weeks 5-8 were performed at 60-65% intensity. Descriptive statistics (Mean ± Standard Error) of all dependent variables were calculated using SPSS/PC+Ver. 21.0K program and the corresponding sample t-test were conducted to determine the differences in RMR, body composition, maximal oxygen uptake, and lipid profile before & after aerobic exercise. The statistical significance level was set as α=.05. Results: There were significant differences in weight and BMI before & after training in the E1 group and E2 group before & after training (p<.001). There were significant differences in body fat percentage and total fat before & after training (p<.01) in both E1 and E2 groups. There were significant differences in maximal oxygen uptake for the E1 group (p<.01) and the E2 group (p<.001) before & after training, but only the E2 group resulted in significant differences in resting metabolic rate (p<0.01). Examining changes in TC, significant differences were found before & after training in both the E1 group (p<.01) and the E2 group (p<.05). No significant differences in levels of TG, LDL-C, and HDL-C were observed in either group. Conclusion: Eight weeks of regular aerobic exercise result in positively improved treatment of obesity in both age groups. Both groups show decreases in body weight, BMI, body fat percentage, lean mass, and TC, as well as increases in resting metabolism rates and maximal oxygen uptake. It is observed that 8 weeks of aerobic training resulted in a variety of positive physiological changes in women with obesity.
