탈취제로 이용되고 있는 지렁이 분변토로 부터 황화수소를 제거하는 황산화 세균 CP-5를 분리하였다. 이 균주는 운동성이 없고 Gram 음성인 단간균 이었으며, cytochrome oxidase와 catalase test에 양성 반응을 보였다. CP-5 균주는 환원형 황합물을 기질로 하는 배지에서 독립영양적인 생장이 가능하였다. 이 균주는 thiosulfate 에서 tetrathionate를 중간생성물로 하여 최종적으로 sulfate로 산화하고, elemental sulfur를 일단 thiosulfate로 산화한 후, sulfate까지 재산화하는 것으로 사료되었다. 독립영양 배지에 yeast extract 를 첨가하면 균의 생장이 촉진되었다. CP-5 균주 현탁액에 H₂S를 2vvm의 유속으로 주입하면 140ppm까지는 거의 완전하게 제거 가능하였다. 본 연구결과로부터 CP-5 균주는 분변토에서 황화수소를 제거하는 대표적인 탈취균주이며, 황화수소 제거를 위한 생물학적 탈취 공정에 활용 가능하다는 것을 알 수 있었다. A new sulfur-oxidizing bacterium which was capable of degrading hydrogen sulfide was isolated from earthworm casts using deodorant materials. The cell of isolate CP-5 was short rod, gram negative and non-motile, the activities of cytochrome oxidase and catalase were positive. The isolate could autotrophically grow in the basal mineral medium supplemented the reduced sulfur compounds such as thiosulfate and elemental sulfur. This bacterium could oxidize thiosulfate and elemental sulfur to sulfate, and the metabolic intermediates were considered as tetrathionate and thiosulfate, respectively. The removal of hydrogen sulfide by the isolate CP-5 was confirmed, and the CP-5 was regarded as one of microorganisms responsible for degradation of hydrogen sulfide in earthworm casts. The isolate CP-5 can be applied to biodeodorization systems for the improvement of removal efficiency of hydrogen sulfide.

Great lateral forces arise commonly on retaining wall, piers and bulwark in harbours, bridge abutments and tower structure. Earth pressure dynamic forces(impact of ships), or wind pressure may be named as typical causes for these forces. This paper based on a series of model tests was performed to proposal the decision method of a allow lateral resistance of single pile under lateral load. Model tests were performed in changing of relative density. The model piles were made of copper tube, and the homogeneous model grounds were used air-dried fine sand enough to get through t.4 sieve. A summary test results were analyzed through the experiment as follows. The allow lateral resistance of the proposal method was larger than existing method as safety factor was applied two, that of the existing method was larger than proposal method as safety factor was applied three. But The allow lateral resistance was same to proposal method and existing method as safety factor was applied 2.5.

The thermal decomposition process of Mo(CO)_6 on chemical vapor deposition was investigated by analyzing the effects of deposition temperature, pressure, and reaction gas on the phase change of deposited films. Mo_2C was deposited at or below 350℃ due to the incompleteness of thermal decomposition of Mo(CO)_6, but Mo films was successfully deposited at 400℃ or higher temperatures. The variation of deposition pressure did not change the dependence of decomposition process on deposition temperature. The activation energy of surface reaction was 5.8 ㎉/mole.

The multilevel grid file(MLGF) is one of multidimensional files for supporting multiattribute accesses efficiently in various advanced applications. In this paper, we evaluate the performance of the MLGF. We first identify four important performance factors: (1) change of the number of directory entries in the exact-match query, (4) number of page accesses occurred in processing a range query. And then, we evaluate each performance factor of the MLGF through extensive experiments using various sets of records. The results reveal thar the MLGF has good performance in all cases regardless of data distributions.

Invasive pulmonary aspergillosis is known to have a poor prognosis and major cause of morbidity and motality in patients with hematologic disease. Without adequate therapy, invasive pulmonary aspergillosis will almost always progress to fatal pneumonia. Early administration of antifungal agents in patient with invasive pulmonary aspergillosis is most important. And surgical resection of aspergillous-infected tissue may be useful in patients with lesions that are contiguous with great vessel and lesions causing hemoptysis. We reported a rare case of surgical resection as curative treatment for invasive pulmonary aspergillosis patient in 58-year-old man who had the history of acute myeloid leukemia.

This study was performed to investigate the effect of composition changes in glasses on the strength and shade of glass-infiltrated alumina ceramics. Six different borosilicate glasses containing MgO, Li₂O and ZrO₂ in the glass composition were prepared, porous alumina compacts were prepared by slip casting and sintered at 1100℃ for 2 hours. Dense composites were made by infiltration of molten glass into partially sintered alumina at 1110℃ for 6 hours. Specimens were polished sequentially form #800 to #2000 diamond wheel, and the final surface finishing on the tensile side was received an additional polishing sequence through 0.3 ㎛ diamond paste. To evaluate the effect of composition change in glass on the shade changes of glass-infiltrated alumina core ceramics, the color was measured by the CIE L^*, a^*, b^* color scale relative to standard source C. The biaxial flexure strength was measured using the ball-on-three-ball method at a crosshead speed if 0.5mm/min. The color change of composites infiltrated with experimental glasses to In-Ceram Glass AL1 showed that L^* values increased but a^* and b^* values decreased with addition of MgO, Li₂O and ZrO₂ in the glass composition. Maximum color difference of experimental glass-infiltrated alumina core ceramics was obtained in the Group B containing 2.4 mol% MgO in the glass composition. The maximum biaxial flexure strength values 47.41 MPa was obtained in the Group E containing 0.3 mol% Li₂O in the glass composition. The observation of fracture surfaces indicated the microstructurally rough surface with a tendency of toughening by crack deflection and crack bridging.

Aluminium is known to have neurotoxic effects. Aluminium compound can also be found in water and can be released from utensils during cooking. We have found that the leaching of aluminium from utensils is enhanced in the presence of trace quantities of fluoride ion. In an experiment conducted to estimate the rate of leaching, we have found that the presence of fluoride in water adjusted with pH 3∼pH 9 and boiled in an aluminium vessel, increased over 12 ppm of aluminium with in 10-40 min. Aluminium concentration was increased to increasing the surface-to-volume ratio of aluminium utensils and heating time. Leaching properties of aluminium ware increased to decreasing pH concentration.
