AIM: To examine incidence of tuberculosis(TB) in gastrectomy patients and investigate the risk factors for developing TB after gastrectomy in patients with gastric ***: A retrospective cohort study of gastrectomy patients with gastric cancer was performed at a university-affiliated hospital in Seoul, South Korea between January 2007 and December 2009. We reviewed patient medical records and collected data associated with the risk of TB, surgery, and gastric cancer. Standardized incidence ratios(SIRs) of TB were calculated to compare the incidence of TB in gastrectomy patients with that in the general Korean population, and risk factors for TB after gastrectomies were ***: Among the 1776 gastrectomy patients, 0.9%(16/1776) developed post-gastrectomy TB, with an incidence of 223.7 cases per 100000 patients per year. The overall incidence of TB in gastrectomy patients, adjusted by sex and age, was significantly higher thanthat in the general population(SIR = 2.22, 95%CI: 1.27-3.60). Previous TB infection [odds ratio(OR) = 7.1, P < 0.001], lower body mass index(BMI)(kg/m2; OR = 1.21, P = 0.043) and gastrectomy extent(total gastrectomy vs subtotal gastrectomy)(OR = 3.48, P = 0.017) were significant risk factors for TB after gastrectomy in a multivariate ***: TB incidence after gastrectomy is higher than that in the general population. Previous TB infection, lower BMI, and total gastrectomy are risk factors for TB after gastrectomy in patients with gastric cancer.

基于高频的中压(MV)逆变器被用于可再生能源电力传输。然而,由于高频链路电子变压器中较高的绕组间寄生电容会导致共模噪声电流的增加,从而使得电能质量受到影响。这种快速电压瞬态响应会导致谐波失真和变压器过热,从而导致电源故障或许多其他电气危险。本文介绍了釆用传统和改进的环形变压器设计的隔离电源的比较研究。设计了半桥高频(10kHz)中压直流一交流逆变器和电源;建造了一个680W的太阳能组件可再生系统。同时使用Matlab-FFT分析的FEM仿真来确定磁芯通量分布并计算总谐波失真(THD)。还用GWInstekLCR仪表和FlukeVT04A分别测量了所有四个变压器原型中的绕组间电容和温度。环形铁氧体磁芯变压器的改进设计提供了更高的耐温性,从而无需使用任何冷却剂或外部电路,同时将寄生电容降低了87%。为确认该方法的有效性,我们进行了实验以及绕组间电容的数学推导。

The lateral stability of Velocity-173, canard-pusher type airplane, has been investigated with and without an extended vertical panel. It is well known that Velocity-173 has an excellent longitudinal stability but a relatively poor lateral stability. To improve the lateral stability, two types of composite sandwich panel have been designed and attached to the vertical tail of Velocity-173. A series of flight test has been performed to measure the effects of the extended vertical tail. Analytical methods, such as maximum likelihood estimation method and real-time parameter estimation method, have been used to extract lateral controllability/stability derivatives from flight test data. This work validates the effects of an extended panel to the lateral stability.

调查了韩国6种不同林龄（10,27,30,32,44和71年生）赤松林（Pinus densiflora）的生物量、碳含量和氮含量.采用收割法采集30株个体作为样本,其中有12株挖掘了全部的根系,采集植物体地上、地下部分、凋落物（CWD）、地被物及矿质土壤样品（0-30cm）进行分析.结果显示,树木生物量最大的是林龄71年生的样地（202.8t/ha）,最小的是林龄10年生的样地（18.4t/ha）;林龄71年生样地的矿质土壤碳、氮储量均高于其他样地,这可能与该样地较高的土壤碳、氮密度有关.生态系统总碳、氮储量从林龄10年生的样地（18.8tC/ha和1.3tN/ha）到林龄71年生的样地（201.4tC/ha和8.5tN/ha）逐渐增高.生态系统总碳储量和树木碳储量都呈现出随着林龄S型增长的趋势,而凋落物、地被物和矿质土壤的氮含量则未显示出随林龄变化而显著变化的趋势.本结果对了解赤松林碳、氮储量的现状及预测未来的生长变化提供有效依据.

目的使用13N-NH，PET显像检测冠脉血流储备（CFR）和相对血流储备（RFR），分析两者之间的关系以诊断冠心病。方法69例稳定性心绞痛患者在2周内接受13N—NH，PET显像和cT冠脉造影（CTA），必要时还行介入冠脉造影（CAG）。通过13N-NH，PET显像检测心肌血流（MBF）、CFR、RFR和相关冠脉供血区域的冠脉血管阻力（CVRref）。采用CTA和CAG评价冠脉明显狭窄（SS）和弥漫性动脉粥样硬化（DA）。比较有和无SS和DA的各冠状动脉的PET检测功能参数。结果有SS和DA的冠状动脉其负荷态MBF显著降低，有SS的冠脉其RFR显著降低，而CFR没有降低。有DA的冠脉其CFR显著降低，而RFR没有降低。在没有SS的冠脉中，有DA的其CFR显著降低，但在有SS的冠脉中，无论有无DA，CFR都相近。相反，无论有无DA，存在SS的冠脉其RFR显著降低。CFR和RFR在24例中（35％）呈不一致的弱正相关性（r=0．269）。在CFR和RFR不一致的冠脉中，CFR降低而RFR正常的冠脉其DA的发生率高于CFR正常而RFR降低的冠脉（75％比25％，P=0．028）。有DA的冠脉其CVR。显著升高，表明DA与潜在的微血管病变具有相关性。结论心肌血流灌注PET显像测定CFR和RFR为诊断CAD提供了更丰富的信息。
