        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.

      • 淨水슬러지의 固化處理에 關한 硏究

        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.

        김경남,신대용,이현종 강원대학교 부설 석재복합신소재 제품연구센터 2002 석재연 논문집 Vol.7 No.-

        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.

      • RT-LAMP를 이용한 콩황화일반모자이크바이러스의 진단

        배대현, 이영훈, 김봉섭, 윤영남, 강범규, 최만수, 구성철, 김현태, 윤홍태, 이수헌, 백인열 忠北大學校 農業科學硏究所 2014 農業科學硏究 Vol.30 No.2

        Soybean yellow common mosaic virus (SYCMV) has been recently reported, it has been occurred a lot with Soybean mosaic virus (SMV) and Soybean yellow mottle mosaic virus (SYMMV) in soybean field. SYCMV belongs to genus of Sobemovirus and induced viral symptoms with yellowing, mottle and mosaic. A reverse transcription loop-mediated isothermal amplification (RT-LAMP) method allowed one-step detection of gene amplification by simple procedure and needed only a simple incubator for isothermal template. This RT-LAMP method allowed direct detection of RNA from virus-infected plants without thermal cycling and gel electrophoresis. In this study, we designed RT-LAMP primers named SYCML-F3/B3/FIP/BIP from coat protein gene sequence of SYCMV. After the reaction of RTLAMP, products were identified by electrophoresis and with the detective fluorescent dye, SYBR Green I. under daylight and UV light. Optimal reaction condition was at 63 for 60min and the primers of RTLAMP showed the specificity for only SYCMV tested in this study.

      • 施肥條件이 사탕무의 生育과 Betacyanin 含量에 미치는 影響

        金度勳,朴賢眞,金賢勍,鄭大守 東亞大學校生命資源科學大學附設 農業資原硏究所 1996 農業生命資援硏究 Vol.5 No.1

        사탕무의 生育과 betacyanin 含量의 變化에 대한 施肥條件의 影響을 알아보기 위하여 室素 0, 10, 15 및 20㎏/10a와 加里 0, 10, 15 및 20㎏/10a 處理하여 試驗한 結果는 다음과 같다. 草長과 葉數는 室素 15㎏/10a 處理區까지는 增加되었으나, 20㎏/10a 處理區에서는 오히려 減少되었으며, 根直徑과 根長도 室素 施用量의 增加에 따른 有意的인 差異가 認定되었다. 그리고 根重은 無處理區에 비해 室素 處理區에서 增加되었으나, 室素 處理區間에는 큰 差異를 나타내지 않았다. Betacyanin 含量은 室素 15㎏/10a와 加里 20㎏/10a 處理區에서 0.126%로 가장 높았고, 生育段階別로는 파종후 110日에 가장 높은 含量을 나타내었다. These experiments were carried out to investigate the effect of nitrogen and potassium application on growth and betacyanin content of sugar beet. The experiments were respectively treated with 0, 10, 15 or 20㎏/10a nitrogen and 0, 10, 15 or 20㎏/10a of postassium, and the results were summarized as fellows. Plant height and number of leaves were increased by 15㎏/10a of nitrogen, otherwise; it was decreased by 20㎏/10a of nitrogen. There were significant differences root diameter and root length by increament of nitrogen application. Root weight was progressively increased by nitrogen treatments compared to the control, although there was no significant differences among the amount of nitrogen treatments. Betacyanin content was high 0.126% in the plot treated with 15㎏/10a of nitrogen and 20㎏/10a of potassium respectively. For the growth stage the corresponding value showed the highest level at the 110th day after seeding.
