This study investigated the distribution of twelve mycotoxins (aflatoxins B1, B2, G1, and G2; ochratoxin A; fumonisins B1 B2; deoxynivalenol; nivalenol; zearalenone; T-2 toxin; HT-2 toxin) in corn by-products (corn bran, cornstarch, gluten, gluten feed, germ, light steep water, liquor) produced by wet-milling Korea. Fifty-two samples were collected from three factories producing cornstarch other by-products. The pretreated on an immunoaffinity column (IAC), then levels 12 analyzed...
Flexible capacitive pressure sensors with a simple structure and low power consumption are attracting attention, owing to their wide range of applications in wearable electronic devices. However, it is difficult manufacture high sensitivity, detection range, limits. We developed highly sensitive flexible sensor based on the porous Ecoflex, which has an aligned airgap can be manufactured by simply using mold micro-needle. The existence precisely structures significantly improved sensitivity...
The gas-phase self-assembly of reduced graphene oxide (rGO) nanoflakes with highly ordered ultrafine titania (TiO2) particles was performed and the resultant hybrid material displayed an enhanced photocatalytic performance, both in producing hydrogen degrading dyes. Freshly synthesized TiO2 nanoparticles (∼35 nm equivalent mobility diameter) were quantitatively incorporated nanoscale rGO (∼36 form TiO2/rGO (∼31 diameter). flakes finally employed to evaluate its activity, it found that...
In this study, Chlorophyll-a (chl-a) prediction model and multiple parameters affecting algae occurrence in Mulgeum site were evaluated by statistical analysis using water quality, hydraulic climate data at (1998~2008).Before the analysis, control chart method effect period of typhoon adopted for improving reliability data.After preprocessing step two methods used study.In 1, chl-a was developed preprocessed data.Another Method 2 significant after step.As a result correlation temperature,...
The microstructure and hardness along the thickness direction of a water-quenched, high-strength thick plate with 40 mm were investigated three specimens from plate: surface, 1/4t, 1/2t (center) thickness, phase transformation behavior according to cooling rate was analyzed through dilatometric experiments. Finally, for each estimated by comparing those specimens. Martensite observed on surface water-quenched due fast rate. On other hand, an inhomogeneous transformed inside relatively slow...
Nanoscale iron (Fe)–silica (SiO2) core–shell agglomerates were conveniently obtained via gas-phase hybridization of freshly produced Fe with SiO2 synthesized in an aqueous medium containing polyethyleneimine. Synthesized Fe–SiO2 employed as nanocarriers for gene transfection and magnetic cell patterning vitro.
Bismuth antimony telluride (Bi-Sb-Te)-based alloys remain the dominant choice for near-roomtemperature thermoelectric cooling applications. One of most studied approaches to improve performance Bi-Sb-Te has been a nanostructuring strategy, suppress lattice thermal conductivity. This study investigates impact incorporating reduced pyrolyzed Pd acetate within Bi0.5Sb1.5Te3 matrix, building upon recent advancements in nanostructured alloys. While addition lowers figure-of-merit (zT) at low...
The Buk-Hang bridge, to be completed mid 2014, is drawing interest for its potential reduce traffic load in the inner city area by completing a full circular road along waterfront. object of this study analyze space-structural impact that bridge can have on city's urban spatial structure. In doing so, utilizes axial map analysis Space Syntax theory with being conducted upon three scenarios: pre-completion post-completion and finally all bridges removed. By using Choice Value, appropriate...
In this study, an improved analytical method for the detection of colorant Brown FK in foods using high-performance liquid chromatography was developed. The method, which employed RC-C18 column and diode array at 254 nm with sodium acetate solution methanol as mobile phases, exhibited good linearity (R2 = 1.0), its limits quantification were determined to be 0.06 0.19 μg/mL, respectively. precision found 0–1.2% accuracy between 86.5% 94.8%. Liquid chromatography-tandem mass spectrometry also...
기반시설이 부족한 녹지지역 및 관리지역 농림지역 자연환경보전지역에서 난개발을 방지하고 환경을 보호하기 위하여 도입된 연접개발제한 제도는 이들 지역의 난개발 방지에는 기여하였지만 연접개발여부의 판단이 모호하고 소규모의 분산개발을 초래하거나 개발행위허가를 피해 산지전용허가를 통한 개발행위가 야기되는 등의 문제가 유발되어 폐지되기에 이르렀다. 그러나 방지를 위해 도시계획위원회의 심의를 받도록 하고 있으나 여전히 위원구성이나 재량권 남용 문제를 안고 있으며, 녹지축 보전대책의 미흡, 공간정보체계의 활용 부족, 법률별 경관관리기준의 불일치, 그리고 물리적 환경규제의 획일화 등 여러 가지 문제들이 나타나고 있다. 따라서 심의제도 운영을 위한 개선방안으로, 구성 기능재편과 전문분야 집중심의제 도입, 동일 상의 지자체들의 경우 개발행위허가 통합조정위원회를 두어 보전방안과 개발행위허가기준 마련, 도시계획정보시스템의 조기구축 활용, 경관관리기준을 지역 실정에 맞게 세부적으로 구축, 시 재량행위...
This study proposes a new topology for the performance test of valve consisting modular multilevel converter (MMC)-based static synchronous compensator (STATCOM). The conventional equipment requires high-voltage AC source several kV rating because number submodules to be tested in should at least six or eight. However, power proposed scheme is DC and not source. voltage range circuit from volts tens volts. Therefore, size cost can reduced considerably compared with method. satisfies...
