목적: To evaluate the positive effects of teratogenic risk counseling in pregnant women inadvertently exposed to medication in early pregnancy. 방법: In a prospective cohort study, 250 pregnant women exposed to medications in early pregnancy were recruited after teratogenic risk counseling at Korean MotherSafe Counsling Center, which has given information about teratogenic risk of medication to pregnant women. Positive effects are evaluated by visual analogue scale(VAS) for perception on teratogenic risk and percent prefering termination of pregnancy after medication exposures in pregnancy. 결과: Mean age of participants is 31.8±5.3years old. Mean gravidity is 2.4±2.1. Medications exposed in early pregnancy include antibiotics, analgesics, anti-inflammatory drugs, antacid and so on. Mean perceptive teratogen risk before and after the counseling is 33.9±1.6% and 15.8±1.6%, respectively. And mean percent prefering termination of pregnancy (≥5) before and after the counseling is 31.1±1.9% and 13.5±1.7%, respectively. 결론: Our data suggest that information on teratogenic risk for pregnant women inadvertently exposed to medication may have positive effects for reassuring pregnant women and preventing termination of pregnancy.

Environmental Microbiology / Microbial Diversity : Calcium Carbonate Precipitation by Bacillus and Sporosarcina Strains Isolated from Concrete and Analysis of the Bacterial Community of Concrete(s)

Microbially induced calcium carbonate precipitation (CCP) is a long-standing but re-emerging environmental engineering process for production of self-healing concrete, bioremediation, and long-term storage of CO2. CCP-capable bacteria, two Bacillus strains (JH3 and JH7) and one Sporosarcina strain (HYO08), were isolated from two samples of concrete and characterized phylogenetically. Calcium carbonate crystals precipitated by the three strains were morphologically distinct according to field emission scanning electron microscopy. Energy dispersive X-ray spectrometry mapping confirmed biomineralization via extracellular calcium carbonate production. The three strains differed in their physiological characteristics: growth at alkali pH and high NaCl concentrations, and urease activity. Sporosarcina sp. HYO08 and Bacillus sp. JH7 were more alkali- and halotolerant, respectively. Analysis of the community from the same concrete samples using barcoded pyrosequencing revealed that the relative abundance of Bacillus and Sporosarcina species was low, which indicated low culturability of other dominant bacteria. This study suggests that calcium carbonate crystals with different properties can be produced by various CCP-capable strains, and other novel isolates await discovery.

When it is raining or snowing, floating debris flows into a lake and raises its turbidity. High level of turbidity in the lake often causes eutrophication, which pollutes the water. In order to collect and present some essential information for effective management plan for water quality, we carried out our research at the watershed of Mandae-cheon located at the upstream of Soyang Lake. We examined water quality at the time of rainfall or snowfall to analyze the changes in the amount of suspend soils(SS) in the lake.

The object of this study is to evaluate the factors affecting the water quality and to propose the influence of dominant factor quantitatively. The correlation analysis was performed to know the correlationship among the water quality items. As a result of partial correlation analysis, it was shown that the water quality items are affected by the rainfall item directly. The factor analysis was performed to grasp some number of factors on each point for deducing the items of similar variable characteristics. The four points were divided into different factor groups. It was grasped that NH_3-N and NO_3-N items have different variable characteristics after comparing the items. The Multiple regression analysis can decrease the number of observation. In the deduced multiple regression formula, it was shown that the rate of T-N, NH_3-N and NO_3-N in the independent variable took about 60% among all the regression formulas.

최효선,고영수 漢陽大學校 韓國生活科學硏究所 1996 韓國 生活 科學 硏究 Vol.- No.14

The objective of this study was to investigate the contamination of trace metals in sesame products on the market. Seven varieties of both domestic and imported sesames(Sesamum indicum L.) were examines. Ten trace metals, i.e. arsenic, cadmium, cobalt chromium, copper, mercury, manganese, molybdenum, lead and zinc, were detected by inductively coupled plasma(ICP) atomic emission spectrometry. The results were summerized as follows : 1) The overall ranges and mean(ppm) were : As, 0.737-0.93(0.80ppm) Cd, 0.076-0.126 (0.084ppm) Co, 0.216-0.574(0.309ppm) Cr, 0.159-0.245 (0.203ppm) Cu, 8.26-12.3(10.45ppm) Hg, 0.069-0.179(0.125ppm) Mn, 11.0-26.4(17.24ppm) Mo, 0.301-1.01 (0.681ppm) Pb, 0.936-1.15(1.036ppm) Zn, 43.1-49.9(45.7ppm) 2) The level of arsenic was below the tolerance limit of the Ministry of Health and Social Affairs and FAO/WHO, but was high value as compared with that of other studies. 3) The levels of lead and cadmium in imported sesame were higher than other samples. 4) Especially, the level of zinc which ranged from 43.1 to 49.9ppm was 8-times higher than the level of other studies. In the cases of hazardous heavy metals such as arsenic cadmium, mercury and lead, the level of arsenic was below the tolerance limit and the levels of cadmium and lead in imported sesames were higher compared to domestic sesames. It is concluded that the tolerance limits of trace metals must be enforced to protect public health from potential contamination problems in sesames.

고리 및 영광 원전 반경 5km 내 11곳의 논토양을 원상대로 재배상자에 채취하여 실험 온실로 운반한 후 벼의 이식 전과 생육중에 ^137Cs을 담수의 표면에 처리하였다. 이식전 처리시 ^137Cs의 토양-작물체 전이계수(m²kg^-1-dry plant)는 토양에 따라 8배 정도의 변이를 보였고 평균은 지역간 차이가 거의 없이 쌀알의 경우 1.1 x 10^-4 , 볏짚의 경우 2.7 x 10^-4 이었다. 분얼초기 처리와 수잉기 처리시 전이계수는 이식전 처리에 비해 대체로 2∼3 배 및 15∼30 배 정도 높았다. 토양 유기물 함량과 전이계수 간에는 정의 상관이 있었다. 본 실험결과에 입각하여 우리나라 논에 대한 일회성 사고침적시 적용할 수 있는 ^137Cs 전이계수의 대표치를 침적시기별로 제안하였다. Undisturbed soil blocks were taken into culture boxes from 11 paddy fields within 5 km radii of Kori and Yonggwang NPPs and carried to a greenhouse where ^137Cs was applied to the surface of standing water before rice transplanting and during its growth. Transfer factors (m²kg^-1-dry plant) of ^137Cs applied before transplanting varied with soils by a factor of about 8. The mean was 1.1 x 10^-4 for hulled rice seeds and 2.7 x 10^-4 for straw without significant regional differences. The ^137Cs applications at the early tillering stage and booting stage resulted in, on the whole, 2∼3 and 15∼30 times, respectively, higher transfer factors than the application before transplanting. A positive correlation was found between soil organic matter and transfer factor. Generic values of transfer factors were proposed for an acute accidental deposition of ^137Cs onto Korean paddy fields in different times of the year.

고층건축물의 방재대책에 관한 연구

This study concerns about a possible fire protection way for high-rise buildings. It is foud that the number of high-rise buildings are increased 29.4% while the number of fire are increased 16% than the year of 1990. The important characteristics of fire on buildings can be described as : 1. It flashes over all around after a certain time period. 2. It is necessary to extinguish the fire on the initial growth since it flashes over 2-5 meter per second through the vertical openings of buildings. Therefor, there is a big possibility that it is developed to uncontrollable fire. The fire protection facilities for fire prevention purposes require a good maintenance system since they are very delicated and complicate. The age of the system also affects the performance of the system and makes the system malfunction. It is found that 96.2% of high-rise buildings had fire detection system and 82.8% of them were in good shape in the year of 1991. However, only 39.2% of the alam system worked properly with 13.2% of utilization. In this study, it is suggested that installation of intelligent fire dection systems developed using the modern electronic techniques for high-rise buildings as well as the components and installation processes. In stallation of the system is strongly recommended since there is a stack effect on the fire at high-rise buildings and it is very difficult to maintain the delicated and complex fire dection systems. The installation of this system requires a big investment on the beginning stage, however it will save many lives while reducing the hazards and losses of fire at high-rise buildings.
