김대현,김문규,임성진 동의공업대학 2000 論文集 Vol.26 No.1

The purpose of this study is to determine the possibility of using as a fill material and cover soil, hardened up to a specific age by making a dosing such as slaked lime, bentonite into the sludge generated during waterworks treatment process with existing treatment system of a ocean dumping. For these reasons, this study carried out a basic physical property test, consolidation test, unconfined compression strength test, extraction test on heavy metals, X-ray diffraction analyzer, scanning electron microscope to determine a characteristic of modified waterworks sludge. In this case that waterworks sludge was modified by being mixed with slaked lime accounting for 10% of its total amount at the age of twenty eight day, the compression strength of the sludge was developed 1.0kgf/㎠ or over. This indicated that the sludge could be used as fill material and cover soil. The extraction test on waterworks sludge modified by slaked lime showed the below of KSP, TCLP standard. Estimation of coefficient of permeability as consolidation test showed less considerably in comparison with reported coefficient of permeability at the landfill site in Seoul Metropolitan area. For this reason, it was found that modified waterworks sludge could be used as fill material and cover soil. Accordingly if waterworks sludge was reused by hardening process, showing a more effecting in terms of economy, environment.

인공모래 제조시 부산물로 발생하는 석분슬러지에 의한 환경문제와 폐기되는 자원의 활용문제를 해결하기 위하여 석분슬러지와 점토 및 폐유리분말을 이용하여 900∼1,100℃로 소성하여 세라믹스 건자재를 제조하였다. 석분 슬러지는 평균입경 16.3㎛, 비표면적 0.42㎡/g, 화학조성은 CaO 46.43wt%, SiO_2, MgO 와 Al_2O_3가 7.83 wt% , 6.17 wt% 및 3.13 wt%이며, 주결정상은 calcite (CaCO_3)와 dolomite (CaMg(CO_3)_2)로서 약 800℃에서 CaCO_3나 CaMg(CO_3)_2의 열분해에 의한 32.52wt% 의 강열감량을 나타내었다. 석분슬러지와 점토를 이용한 시편(No. 1, 4, 7, 10 및 13)은 점토의 첨가량과 소성온도가 증가함에 따라 시편의 부피비중 및 압축강도는 증가하였으나 기공률과 흡수율은 감소하여 No. 1, 4, 및 7 시편은 부피비중 1.78∼1.98, 기공률 6.4∼12.5%, 흡수율 10.3∼12.7%, 압축강도 264∼370kgf/㎠을 나타내었다. 폐유리분말을 첨가한 시편(No. 2, 5, 6, 8, 9, 10 및 12)의 부피비중과 압축강도는 1.91∼2.63 및 213∼895kgf/㎠로서 폐유리분말의 첨가가 시편의 소결성과 압축강도의 향상에 기여하여 세라믹스 건자재로 사용이 가능하였다. The utilization of waste stone powder sludge produced secondarily from artificial sand plants of Ssangyoung resource development (Co.) and general waste, as was classified, became very important to solve the environmental problem and waste materials recycle. In the chemical composition of stone powder sludge, the amount of CaO was 46.43wt%, SiO_2, MgO and Al_2O_3 were 7.83 wt% 6.17 wt% and 3.13 wt%, respectively. The mean average particle size was 16.3㎛ and specific surface area was 0.42㎡/g. Main crystal phases were calcite (CaCO_3) and dolomite (CaMg(CO_3)_2) and ignition loss was 32.52wt% because of decomposition of CaCO_3 or CaMg(CO_3)_2. Specimens were fabricated by mixing the waste stone powder sludge, low-grade clay, waste glass powder and sintering at 900∼1,100℃ for 2 hours. The density and compressive strength of specimen increased with increasing the sintering temperature and the amount of clay. The specimen showed the bulk density of 1.78∼1.98, porosity of 6.4∼12.5%, water absorption 10.3∼12.7% and compressive strength of 264∼370 kgf/㎠. Those of the specimen heated at 1,050℃ increased with increasing the added amount of waste glass powder, bulk density was 1.91∼2.63 and compressive strength was 213∼895 kgf/㎠. Therefore, the waste stone powder sludge can be used as a constructional materials.

형대진,김승구,조현준,박경환 동아대학교 정보기술연구소 2006 情報技術硏究所論文誌 Vol.14 No.1

In this paper, we introduce the method for developing the mobile 3D game engine based on the WIPI platform which has been proposed as the mobile standard platform. Our game engine is designed so that it supports OpenGL-ES and JSR-184 that are mobile 3D graphic APIs. Our game engine has a mobile emulator operated on PC and SDK to support mobile programming in PC environments. Mobile 3D game developers can use the APIs at various levels. Also, the game engine is developed in modular in order to support various game genres.

김충현,이영하,나영언,신대환 충남대학교 의과대학 지역사회의학연구소 1991 충남의대잡지 Vol.18 No.2

This study was attempted to find the cell-mediated immune responses and infection aspects of Pneumocystis carinii in immunosuppressive mice. The experimental groups were administered the suppressive regimen consisting of cortisone acetate 2.5mg injected subcutaneously twice a week, a low(8%) protein diet, and tetracycline in the drinking water(1mg/ml) for 10 weeks. From the 1st week after cortisone acetate injection, the number of P. carinii cysts in the lung specimens were examined by Gomori's methenamine silver stain at 1 week interval for 10 weeks. And the blastogenic response of spleen cells treated with Con. A (5.0㎍/ml) was examined by [^3H]-thymidine incorporation assay at the same time. The results obtained in this study were as follows: 1. The number of P. carinii cysts were remarkably increased in the lungs from 2 weeks to 4 weeks, and thereafter was slowly increased throughout the experiment. 2. The blastogenic response of Con. A treated-splenocytes from mice injected with cortisone acetate was significantly declined as compared with those of the control mice(p<0.05). 3. There were not correlation between the number of P carinii cysts in the lung specimens and the blastogenic responses of splenocytes to Con. A(correlation coefficient, r=0.38285, p<0.2749).

Up to the present, we have used general 3D modelling tool for 3 dimensions visualization of electronic parts. If we use general 3D modelling tool, we are consumed many time and effort because it is not optimized modelling of electronic parts. Therefore we need technical 3D modelling tool for electronic parts. In this paper, in order to solve this problem, we develop the graphic tool that model and visualize the electronic parts as 3 dimensions.

A study was carried out to investigate the effect of growth regular on protein content, PAL and peroxidase activity in rice seedling plants, Akibare, a Japonica type variety. ABA(0.1, 1, 10ppm), 2.4-D(10, 100, 1000ppm), and GA(0.05, 0.5, 5ppm) were respectively treated for 5 days to the nee seedling plants which were grown for 20 days. The results were summarized as follows. In stems, the protein content showed the highest value in the plot treated with GA for 5 days, although ABA and 2.4-D treated plots showed no significant differences compared with the control. PAL activity in the plot treated with GA for 5 days and in the plot treated with 2.4-D for 10 days were respectively higher than control. On the contrary, it was low in the plot treated with ABA. PAL activity in roots was respectively higher in the plots treated with GA for 5days and 2.4-D for 10 darts than the control. According to increment of days seedling growth, peroxidase activity was respectively maintained in the plot treated with ABA, 2.4-D, and GA, although it was decreased in the control.

With environmental problems and pollutions accumulated by continuous urban development projects, it is becoming necessary to develop in consideration of environmental effects. On this study, it is suggested the critical point of biotope space factor and the supplement device. Natural ground area ratio is functioned as important factor in urban area. So in region, high-rated in natural ground area ratio, or in new urban development area, it is necessary to get supplement tool for conserving preferentially natural ground area. And it is considerable to ply individual environment planning indicator in case of need. This study has main contents as follows; biotope space factor was applied to actual case, rebuilding housing complex in Cham-sil to diagnosis ecological level and to lead more ecologically sound plan. After considering all the factors there was the critical point in using as just one tool, biotope space factor, so we suggested supplement device to solve this problem for an example, by regional characteristics, biotope space factor and individual environmental planning factor will be used together.
