Background： The global network of eddy-covariance （EC） flux-towers has improved the understanding of the terrestrial carbon （C） cycle, however, the network has a relatively limited spatial extent compared to forest inventory data and plots. Developing methods to use inventory-based and EC flux measurements together with modeling approaches is necessary evaluate forest C dynamics across broad spatial extents. methods： Changes in C stock change （AC） were computed based on repeated measurements of forest inventory plots and compared with separate measurements of cumulative net ecosystem productivity （~NEP） over four years （2003 - 2006） for Douglas-fir （Pseudotsuga menzies# var menziesil} dominated regeneration （HDF00）, juvenile （HDF88 and HDF90） and near-rotation （DF49） aged stands （6, 18, 20, 57 years old in 2006, respectively） in coastal British Columbia. AC was determined from forest inventory plot data alone, and in a hybrid approach using inventory data along with litter fall data and published decay equations to determine the change in detrital pools. These AC-based estimates were then compared with Y_NEP measured at an eddy-covariance flux-tower （EC-flux） and modelled by the Carbon Budget model - Canadian Forest Sector （CBm-CFS3） using historic forest inventory and forest disturbance data. Footprint analysis was used with remote sensing, soils and topography data to evaluate how well the inventory plots represented the range of stand conditions within the area of the flux-tower footprint and to spatially scale the plot data to the area of the EC-flux and model based estimates, Results： The closest convergence among methods was for the juvenile stands while the largest divergences were for the regenerating clearcut, followed by the near-rotation stand. At the regenerating clearcut, footprint weighting of CBm-CFS3 TNEP increased convergence with EC flux Z_NEP, but not for AC. While spatial scaling and footprint weighting did not increase convergence for AC, they d

Journal of materials Science & Technology 2010年第4期26卷 371-374页

Atomic layer deposition （ALD） has become an essential deposition method for forming nanometer scale thin films in the microelectronics industry, and its applications have been extended to multi-component thin films, as well as to single metal oxide films. In order to investigate the development of the surface structure of ultra-thin film qualitatively as well as quantitatively, ALD processes are simulated with a molecular scale. For this simulation, the film materials are deposited on a imaginary substrate that consists of small lattice. The deposition behaviors are described by using random deposition （RD） model or random deposition with surface relaxation （RDSR） model as the ALD growth mode, and the proposed model was applied to the deposition of SrO-TiO2 thin films. Through this work, growth characteristics such as surface morphology, deposited film coverage can be predicted.

听力障碍的临床管理包含各医疗机构间能广泛适用的、统一的完善流程,听力师能借此评估听力状况并为交流障碍提供康复服务。然而,当患者以耳鸣为主诉就诊时,他们的治疗却得不到系统保障。耳鸣有许多治疗方案,但是大多都没有明确依据。因此,耳鸣患者很难对最适合自己的治疗做出判断,只有为耳鸣的临床管理建立协商一致的指导方针,这种状况才能改变。评估和干预是耳鸣管理的两个主要组成部分,本文提供了一个循序渐进的指南,描述了耳鸣听力学管理(audiologic tinnitus management,ATm)的过程是如何展开的,供听力师对耳鸣患者进行基本的评估,其核心为使用现有问卷和标准听力检测设备。

Treatment satisfaction after I year high-power potassiumtitanyl-phosphate photoselective vaporization of the prostate

Asian Journal of Andrology 2010年第5期12卷 728-734页

作者： ja Hyeon Ku min Chul Cho Hyeong Seok Kim jae-Seung Paick Soo Woong Kim Department of Urology Seoul National University Hospital Seoul 100-744 Korea

To investigate the factors that influence treatment satisfaction after high-power potassium-titanyl-phosphate （KTP） laser vaporization of the prostate, we compared the characteristics between patients who were satisfied and those who were not satisfied. In all, 97 patients aged between 53-82 years （median age 67 years） underwent high-power KTP laser vaporization of the prostate for lower urinary tract symptoms due to benign prostatic hyperplasia. At 12 months postoperatively, 60 patients were satisfied with the treatment, whereas 37 were dissatisfied. Although there were no differences in International Prostate Symptom Score （IPSS） values at baseline, the satisfied group scored better in total IPSS at 1, 3, 6, and 12 months postoperatively （P 〈 0.05）. At baseline, the maximum flow rate （Qmax） was lower in the dissatisfied group and remained low throughout the follow-up period, with the exception of 1 month postoperatively （P 〈 0.05）, compared with the satisfied group. There were no differences in other objective data between the two groups, including post-void residual and the number of voids based on the frequency-volume charts. In a multivariate model, a higher bladder contractility index was associated with a greater likelihood of treatment satisfaction 12 months after high-power KTP laser vaporization （odds ratio 1.024, 95% confidence interval 1.001-1.048, P 〈 0.05）. Patients who were not satisfied following the surgery had a smaller improvement in subjective symptoms and Qmax. In addition, our findings suggest that the relative risk of treatment dissatisfaction following high-power KTP laser vaporization was increased in patients with weak detrusor contractility.
