The present study was conducted to elucidate some characteristics of soy protein hydrolysates. The soy protein was obtained from defatted soy power by the treatment of n-hexan. The hydrolysates of soy protein were prepared from hydrolysis by bromelian and pepsin with the two kinds of samples of precooking for 30 min in steam oven and noncooking, and fractionated through Bio-gel P-4 column chromatography. Fractions of hydrolysates separated on the Bio-gel column chromatography were carried out to SDS-PAG electrophoresis, resulting to show some different bends from 66kD to 14.2kD of molecular weight. In addition, the fractions showed different activities of superoxide dismutase. From these results, it was found that the hydrolysates could be available to use in a lot of food industrial fields as new functional food materials because the hydrolysates had different characteristics in electrophoresis and could increase the activity of superoxide dismutase.

Attempts were made to investigate the levels of chemical components and detoxification of the salted puffer overies, Fugu xanthopterus, "Ggachibog" and Fugu rubripes rubripes, "Chambog", processing of solid salt mixtures containing sodium bicarbonate, during storage period. Fresh ovaries of the puffers were divided into three portions, sprinkled with a solid salt mixture containing 0,1 or 2% NaHCO₃, and were stored at room temperature for 12 weeks. The samples were examined at each step and assayed for pH, VBN, amino-N, toxicity and thin- layer chromatogram pattern. The results were summarized as follows: The values of pH were appeared to be different with the added amount of siodium bicarbonate and the values of pH were over 7.0 in a salt mixture containing 2% NaHCO₃. The change of VBN value was also revealed about 85mg/100g in A division and 90-100mg/100g in both B and C, respectively, in the salted ovary of puffer "Ggachibog" from 8 weeks. In case of salted product from the "Chamboh" ovary, it had slightly lower value than that of "Ggachibog" ovary. Also, the value of amino-N was increased until 4-6 weeks and was slowly down after the weeks in all samples. All salted products were found to lose most of the toxicity during storage period when the salt containing NaHcO₃was used for sprinkling. In the case of raw ovaries being weak toxicity below 5.0 MU/g or 24.1 MU/g, the toxicity of salted product was dropped near the level to be edible. Therefore there was significant detoxification of the puffer ovaries by the salt mixture containing sodium bicarbonate. Finally, the toxins isolated from each raw puffer ovary were detected to be TTX-related components by thin-layer chromatogrphy.

Iron and iron nitride nanoparticles were synthesized by chemical vapor condensation (CVC) process, using a precursor of Fe(CO)_(5) and carrier gas of NH₃. Phase change and crystallization behaviors of as received particles were mainly examined by TEM technique. Only α-Fe nanoparticles were formed at the lowest decomposition temperature of 500℃. As the temperature increased, the crystallization of α-Fe nanoparticles was suppressed and Fe₃N nanoparticles were begun to be formed. Finally full crystallization of Fe₃N was observed at 1000℃. Typical size of the α-Fe and Fe₃N particles was less than 30 nm in diameter.

도시화 및 산업화에 따른 중금속 원소들의 분삭 특성과 오염 양상을 파악하고 중금속 원소들의 산출 상태를 규명하기 위하여 서울시 영등포구와 구로구에 있는 34개 중학교의 토양과 분지 시료 총 102개를 채취하여 pH측정과 Pb, Cu, Zn 및 Cd의 중금속 원소들의 함량을 측정하였으며 중금속 함량이 높은 몇가지 시료에 대해 연속추출법을 실시하였다. 연구 지역 중학교의 토양의 pH는 화단 토양이 중성 및 약알칼리성을 운동장 토양이 약알칼리성을 나타낸다. 연구 지역 중학교의 중금속 원소의 함량은 분진의 함량이 높게 나타났고, 지역별로는 Pb와 Cd가 교통량 밀집 지역에서, Cu와 Zn이 공단지역에서 함량이 높게 나타났다. 연속 추출법에 의한 분진의 실험 결과 Pb는 철, 망간 산화물에 결합된 형태로 Cu와 Zn은 이온교환 가능한 형태로 존재하고 있어 Cu, Zn의 이동도가 좋다. 중금속 원소 들의 상관성 검토에서 연구 지역은 다양한 오염원이 존재하는 지역이므로 Pb, Cu 및 Zn의 상관성과 Pb와 Cd의 상관성이 좋다. 다른 수도권 위성 도시와 비교해 볼때 서울 지역의 학교 환경에서는 공업단지의 Cu, Zn의 오염보다 차량증가, 교통체증에 의한 Pb, Cd의 오염이 점점 진행되고 있음을 볼 수 있다. 원소들의 분포 특성 및 오염 지수의 조사 결과 영등포구, 구로구에 위치한 중학교 내의 분진은 거의 모든 지역이 Cd를 제외한 Pb, Cu및 Zn의 중금속 원소의 함량이 높으며, 오염 지수도 1이상의 값을 나타낸다. 특히 공단 지역보다는 교통량이 많은 지역의 오염지수가 더 높다. Soil and dust samples collected from the Youngdungpo-ku and Kuro-ku area in Seoul metropolitan city were analyzed for Pb, Cu, Zn and Cd to investigate their dispersion patterns and pollution level of heavy metals by urbanization and industrialization. Garden soils in the school range from 5.9 to 7.8 in pH and playground soil from 7.3 to 10.5. No difference is in pH values between the polluted and the non-polluted school areas. High concentration of Pb and Cd in school dusts were found in dense traffic area. However, many schools in the industrial area are highly contaminated with Cu and Zn. The result of sequential extraction analysis of the dusts indicates that Pb is mainly bound to Fe and Mn oxides and Cu and Zn is bound to ion exchangeable fraction. The Pb-Cd pollutants could be originated from the identical sources based on a good correlation of Pb-Cu-Zn and Pb-Cd. It suggests that Cd and Pb in dusts be derived from vehicular emissions and wearing tires. The contamination of Pb and Cd in the school area due to vehicular emissions has been notably increased rather than Cu and Zn contamination caused by factorial activities. The pollution index of school area is more than 1, indicating a relatively high contamination of heavy metals such as Pb, Cu and Zn except for Cd.

In this paper, we tried to acquire the spatial information of unmanned mobile objects from the changes of measured values of illuminance sensor attached to unmanned moving objects in the indoor environment restricted by place and time. Therefore, the correlation of illuminance sensor according to single light source according to the position of unmanned mobile object is deduced. From this correlation, indoor positioning technique of unmanned mobile object is developed. As a result, the correlation between the illuminance sensor and the illumination position increased as the illuminance became closer to the light source. The correlation between data of illumination sensor and location of unmanned vehicles was increased as the distance from the light source was increased. There was less relationship between direction of sensor and distance from the light. The relationship between the distance from the light source and the data of illumination sensor was shown as a sixth polynomial equation. The illumination sensor under single light source might be used for indoor location information of unmanned vehicles. The additional experiment of finding position need to be verified to the in multiple source using illumination sensor.

김종국,홍희택 全北大學校 附設 都市및環境硏究所 1998 都市 및 環境硏究 Vol.13 No.1

Adsorption and biodegradation of 1,1,1-Trichloroethane(1,1,1-TCA) which is a common contaminant found in groundwate were investigated in soils to predict the behavior and fate of 1,1,1-TCA in the environment. 1,1,1-TCA was biotransformed in the soil to dichloroethane(DCA) and chloroethane(CA). The biodegradation rate of 1,1,1-TCA was related to the organic carbon content in soils. About 16∼91% of initial 1,1,1-TCA was transformed to DCA and CA during the experimental period. The measured biodegradation rate contants of 1,1,1-TCA were in the range of 0.004d^-1 to 0.099d^-1

Background and objectives : The long-term survival in patients with non-Hodgkin's lymphoma (NHL) after conventional dose chemotherapy is about 35% and the rest of the patients tend to have relapse. So, in relapsed or refractory NHL, we compared the outcome of patients undergoing high-dose chemotherapy with autologous peripheral blood stem cell transplantation(APBSCT) with only salvage chemotherapy of cisplatin, dexamethasone, mitoxantrone, and etoposide(CDME). Materials and methods : From June 1993 to December 1999, 25 patients with relapsed or resistant NHL were treated with CDME regimen as salvage chemotherapy. Twelve patients were received four cycles of CDME chemotherapy, and 13 patients were received high-dose chemotherapy with APBSCT following two cycles of CDME chemotherapy. Results : The median follow-up duration was 12.8 months(range:4-68). The overall response rate was 41.7% (complete response rate 25%, partial response rate 16.7%) in 12 patients with CDME only. Thirteen patients who were treated with high-dose chemotherapy with APBSCT achieved 61.5% complete response rate and 15.4% partial response rate, with an overall response rate of 76.9%. The estimated 3-year progression-free survival rate was significantly higher among patients who received high-dose therapy than patients who received CDME only(41.5% vs 20.0%, p<0.05). And, 3-year overall survival rate was significantly higher among patients who received high-dose therapy(51.3% vs 25.0%, p <0.05). Conclusions : In relapsed or refractory NHL, CDME chemotherapy is an effective salvage chemotherapy and allow peripheral blood stem cell collection. Also, high-dose chemotherapy with APBSCT following CDME is superior to CDME salvage chemotherapy only.
