The soils and plants were sampled from 26 sites of Deogpyeongri, Goisangun, which had been found to be one of the uranium deposit areas. Uranium levels of the samples were determined and the amount of uranium intake by the residents through the food-chains was estimated. The average uranium concentration of Deogpyeongri soils was 15.5ppm with a range of from 4.9 to 43.6ppm showing rather higher values than those of control area, Yangjugun and Icheongun, Gyeonggi-do. The average uranium content of the plant samples from Deogpyeongri was 0.69ppm, about twice the uranium concentration of the control samples. The daily intake of uranium by an adult lived on the agricultural food stuffs produced in Deogpyeongri, was estimated to be about 247㎍, eqivalent to 0.83×10^(-4)μCi, which is much higher activity compared to the daily intake cf uranium by New York citizen, 1.3㎍. However the calculated uranium level accumulated in the human body of Deogpyeong area was 2.03×10^(-4)μ which is still lower than 0.2μCi, the maximum permissible burden in total body recommended by the ICRP.

열 유동 시뮬레이션을 통한 바닥 난방과 온풍기의 빈대 구제를 위한 열처리 비교 분석

김태순,박수현 대한임상건강증진학회 2023 Korean Journal of Health Promotion Vol.23 No.4

연구배경: 빈대 구제에는 살충제 외에도 비화학적 방법이중요하며 가장 효과적인 방법은 열처리이다. 바닥 난방이주거용 건물에 널리 쓰이는 한국에서는 이러한 열처리에 바닥 난방이 가진 이점을 살릴 수 있다. 방법: 실내 공기의 유동과 열전달을 모사하는 시뮬레이션을 수행하여 바닥 난방 방식과 열풍기 방식으로 빈대 구제를 위한 열처리가 적용되는 상황에서 각각의 온도 분포를비교 분석하였다. 결과: 가정한 조건에서 바닥 난방의 실내 온도는 열풍기난방보다 평균이 낮지만 보다 균일했고, 국지적으로 차가운지점이 바닥 난방일 때 사라졌다. 결론: 빈대 구제를 위한 균일한 고온 열처리에 바닥 난방이 열풍기보다 유리한 점이 있음을 확인하였다. Background: Non-chemical methods are as important as pesticides to control bed bugs. The most effective method is heat treatment. Underfloor heating is widely used in residential buildings in Korea, and the benefits of floor heating can be utilized in heat treatment for bed bug control. Methods: Simulations of indoor air flow and heat transfer were performed to compare and analyze the temperature distributions with different heating methods for bed bug control using floor heating and fan heater methods. Results: Even though the average indoor temperature of floor heating was lower, it was more uniform with floor heating than that of fan heating under the assumed conditions. Local cold spots disappeared with the floor heating method. Conclusions: It was confirmed that floor heating has advantages over fan heating to achive uniform high temperatures during heat treatment for exterminating bed bugs

Fly Ash 를 利用한 土壤改良濟 合成과 利用

金台淳 建國大學校 附設 農業資源開發硏究所 1992 農資源開發論集 Vol.17 No.-

An attempt was made for synthesizing zeolite by use of the fly ash from the coal-fired electric power plant. The fly ash zeolites show higher CEC values(344-418 meq/100g) as compared with that of the natural zeolites(100-199 meq/100g). The surface area of the zeolite particles is also shown larger values (23.08-42.86 ㎡g?) than that of the natural zeolite(16.15 ㎡ g?). The XRD spectra of the fly ash zeolite indicate that the peaks are well corresponding with the peak locations of the sodalite. Higher dry matter yields, as whole plant, leaves, and roots of the radishes, were obtained by treating with the fly ash zeolite from the pot experiment that carried out in the glass house.

沃川系 土壤 Uranium에 관한 硏究

金台淳 建國大學校 附設 農業資源開發硏究所 1990 農資源開發論集 Vol.15 No.-

The uranium concentration of soils of the Deogpyeong and Daejeon-Ri, Cheongcheon-Myeon, Goesan-Goon, Chungcheong Buk-Do, is known to be higher than that concentration of the other soils. So that it is aimed to be perfect to clarify the reasons like that, for this, a study was carried out that concerning on the mineralogy of the Ogcheon group and on the characteristics of soils from the Ogcheon in this paper. The U concentration of the problem soils are in the ranging from 4.9 to 43.6ppm with an average value of 17.4 ppm while the other soils are from 4.8 to 12.2 ppm and showing 9.9 ppm as the mean value. The higher U values could be explained as to be due to the presence of uraninite, torbernite, tyuyamumite, and autunite which are embedded in the graphite slate and in the graphitic materials of the Chang-Ri sublayer of the Ogcheon group. The uranium minerals, furthermore, might have been received the metamorphism and the weathering that resulted in dissolution of the uranium and finally that are recrystallized around the soil minerals in the ground soil surfaces. Among the soils of the Deogpyeong and Daejeon-Ri areas, the soils containing the uranium minerals are found in the Heugseog series soil that derived from the phyllite or dark-colored schist of the Ogcheon group. The soil is also mixed black plate-shaped cobbles. The other soils that also associated with the Heugseog series are the Banggog and Jonggog series soils. Their parent materials are also the same with the Heugseog series. The soil taxonomic characteristics of the Heugseog series is a Dystric Fluventic Eutrochrepts and for Banggog and Janggog soils are Fluvaquentic Eutrochrepts and Typic Haplaquepts respectively.

이름대기과제와 부적점화과제에서 나타난 수학학습부진 아동의 억제 능력

김태순,현성용 大邱大學校 社會科學硏究所 2008 社會科學硏究 Vol.14 No.1

본 연구의 목적은 수학학습부진아의 수학학습부진의 원인이 억제능력의 결함에 의한 것인지, 억제능력에 대한 발달상의 지체로 인한 것인지를 확인하고자 하는 것이다. 본 연구의 피험자는 초등학교 3학년 49명, 5학년 28명으로 총 77명이며, 그 중 학습부진집단이 24명, 정상집단이 53명이다. 실험과제는 이름대기 과제와 부적점화 과제를 사용하였으며, 모든 실험은 개별적으로 실시되었다. 실험 결과, 수학학습부진 아동은 수 정보처리를 방해하는 관련 없는 정보를 억제하는 과정에 결함이 있는 것이 아니라 수 정보를 억제하는 과정의 속도가 느리기 때문에 학업 수행에서 낮은 성취를 보이는 것으로 나타났다. 또한 수학학습부진 아동들의 억제 능력은 자신의 연령보다 대략 2년 정도 지체된 것으로 나타났다. The purposes of this study was to investigate whether the mathematics underachievers could inhibition of irrelevant stimulate in naming tasks and negative priming task and they slowed developed delays those tasks. A total of 77 children, consisting of 49 children from 3rd grade and 28 children from 5th grade participated in this experiment. The results of the study were as following. The mean response time in Quantity-Inhibition task was longer than Quantity task in all groups. The performances of 3rd grade children were lower than 5the grade. and the performance of mathematic underachievers were likely to be lower than normal controls in Quantity-Inhibition task. The mean response time in Object-Inhibition task was longer then Object task in all groups. The performance of mathematics underachivers in 5th grade was likely to be lover than normal controls. The mean response time in Objects-Shifting task was longer than in Object task in all groups. Although the differences between 3rd and 5th grade were not statistically significant. mathematics underachievers showed the tenderly of low performance than normal controls. From the results of the negative priming task, the 3rd grade children did not show not inhibition effect. But 5the grade showed inhibition effect. Both of control groups and mathematics underachiever groups did not shown inhibition effect. These could be interpreted show that the low perform mathematics may not be affected from the deficit of inhibition but from the retardation of development.
