AIM: To describe the clinical features and multimodal images of unilateral foveomacular retinitis in young Korean soldiers. METHODS: Ten patients having foveomacular retinitis were included. Fluorescein angiography, fundus autofluorescence(FAF), infrared reflectance(IR), and spectral-domain optical coherence tomography(SD-OCT) were ***: All patients were young males experienced insidious visual decline without exposure to bright light. Initial and final vision ranged from hand movement to 20/20(median 20/200) and 20/2000 to 20/20(median 20/500), respectively. Vision decreased in 6 patients while improved in two. Typical macular abnormality was yellow granular spots. SD-OCT showed ellipsoid zone(EZ) or interdigitation zone(IZ) disruption of fovea. The degree of EZ/IZ damage correlated with vision. Lesions were clearly visualized through IR and matched with SD-OCT ***: This is the first case series of foveomacular retinitis diagnosed with multimodal imaging. Foveomacular retinitis should be suspected in sudden unilateral visual decline especially in young soldiers. SD-OCT is the most important diagnostic modality.

The aim of this study was to determine the unit load of NPS （non-point source） pollutants including organic variables such as BOD （biochemical oxygen demand）, COD （chemical oxygen demand） and DOC （dissolved organic carbon）, nitrogen and phosphorus constituents, and suspended solids （SS） and their event mean concentration （EMC） of runoff flows from a water-shed of mixed forest land use by intensive field experiments. Field monitoring for continuous measurements of rainfall, flow, and water quality was conducted over 12 storm events during 2008-2009 using automated and manual sampling methods. The EMCs of individual runoff event were estimated for each water quality constituent based on the flow rate and concentration data of runoff discharge. The average EMCs of BOD, COD, DOC, SS, TN （total nitrogen）, NH4^＋-N, NO3^--N, TP （total phosphorus）, PO4^3-P from the mixed forest land were 1.794, 3.498, 1.462, 10.269, 0.862, 0.044, 0.634, 0.034, and 0.005 mg/L, respectively. The annual unit loads of BOD, COD, DOC, SS, TN, NH4^＋-N, NO3^--N, TP and PO4^3--P were estimated as 66.9, 133.2, 55.5, 429.8, 36.5, 1.6, 26.9, 1.3 and 0.1 kg/（ha·yr）, respectively. In addition, affecting parameters on the EMCs were investigated by statistic analysis of the field data. As a result, significant correlations with precipitation, rainfall intensity, and total runoff flows were found in most constituents.

考虑到多智能体系统在复杂环境中受到外部干扰和控制器受到恶意攻击等问题,本文旨在研究一类受扰非线性多智能体系统在事件触发机制和脉冲控制下的领导跟随拟一致性。不同于现有文献中需要事先指定最小事件触发间隔,本文所设计的动态事件触发机制通过其参数的选择加以保证,从而避免了芝诺行为的发生。基于此机制,进一步给出了系统实现拟一致性的一些充分条件以及相应误差上界的估量值。最后,通过数值仿真例子验证了结果的有效性。

Titanium-aluminum-nitride（TiAlN） films were grown by plasma-enhanced atomic layer deposition（PEALD）on 316 L stainless steel at a deposition temperature of 200 °C. A supercycle, consisting of one AlN and ten TiN subcycles, was used to prepare TiAlN films with a chemical composition of Ti（0.25）Al（0.25）N（0.50）. The addition of AlN to TiN resulted in an increased electrical resistivity of TiAlN films of 2800 μΩ cm, compared with 475 μΩ cm of TiN films, mainly due to the high electrical resistivity of AlN and the amorphous structure of TiAlN. However, potentiostatic polarization measurements showed that amorphous TiAlN films exhibited excellent corrosion resistance with a corrosion current density of 0.12 μA/cm^2, about three times higher than that of TiN films, and about 12.5 times higher than that of 316 L stainless steel.
