＜正＞ Population dynamics of the Baikal Teal Anas Formosa in Korea were studied during the last two decades. This population has increased over the past two decades from a few in the early 1980’s to 350,000 individuals in the winter of 2000-2001 in the nationwide winter watcrbird census. During the 1940’s, Baikal Teals were widely distributed in Korea where it was very abundant winter visitor. After that the birds were significantly decreased,

目的探讨健脾栓治疗溃疡性结肠炎(UC)的临床效果,以凝聚韩捷教授使用健脾栓治疗溃疡性结肠炎经验,以期为临床实践提供借鉴和参考。方法基于真实世界研究(RWR),以河南中医药大学第一附属医院系统数据库为依托,采用回顾性队列研究方法选取2014年1月-2019年12月所有住院诊断为轻、中度UC的680例患者作为研究对象。以是否使用健脾栓分为健脾栓组(460例)及非健脾栓组(220例),健脾栓组根据梅奥(Mayo)评分分为健脾栓轻度组、健脾栓中度组,各230例(3~6分为轻度组、6~10分为中度组)。健脾栓组在口服美沙拉嗪基础上,应用健脾栓纳肛治疗;非健脾栓组口服美沙拉嗪治疗。3组以症状积分、Mayo评分、粪便钙卫蛋白、肠镜积分、临床疗效、复发情况为观察指标。随访6个月后,分析对比以上指标变化。结果健脾栓轻度组与中度组在症状积分、Mayo评分、粪便钙卫蛋白、肠镜积分、临床疗效方面均明显优于非健脾栓组(P<0.05)。结论健脾栓组的效果明显优于非健脾栓组,健脾栓的使用可为临床提供一条有效的治疗UC并可维持缓解的方案。

Herein,we report on surface plasmon(SP)-sensitive semitransparent inverted polymer photovoltaic(PV)devices that are based on multilayered material systems consisting of poly(3-hexylthiophene):fullerene-derivative bulk-heterojunction PV layers and thin gold or silver *** demonstrate that these PV devices allow the simultaneous generation of both electrical power and SPs on their anodes for photoexcitation just above the optical absorption edge of the PV layers,resulting not only in attenuated total reflection,but also in attenuated photocurrent generation(APG)under the SP resonance(SPR)***,we also confirm that the biomolecular interaction of biotin–streptavidin on the PV devices can be precisely detected via apparent SPR angle shifts in the APG spectra,even without the need for complex attenuated total reflection *** highlight our view that APG measurements made using these PV devices show great potential for the development of future generations of compact and highly sensitive SPR-based optical sensors.

Transfusion-transmitted infections including hepatitis B virus(HBV) have been a major concern in transfusion medicine. Implementation of HBV nucleic acid testing(NAT) has revealed occult HBV infection(OBI) in blood donors. In the mid-1980 s, hepatitis B core antibody(HBc) testing was introduced to screen blood donors in HBV non-endemic countries to prevent transmission of non-A and non-B hepatitis. That test remains in use for preventing of potential transmission of HBV from hepatitis B surface antigen(HBs Ag)-negative blood donors, even though anti-hepatitis C virus testshave been introduced. Studies of anti-HBc-positive donors have revealed an HBV DNA positivity rate of 0%-15%. As of 2012, 30 countries have implemented HBV NAT. The prevalence of OBI in blood donors was estimated to be 8.55 per 1 million donations, according to a 2008 international survey. OBI is transmissible by blood transfusion. The clinical outcome of occult HBV transmission primarily depends on recipient immune status and the number of HBV DNA copies present in the blood products. The presence of donor anti-HBs reduces the risk of HBV infection by approximately five-fold. The risk of HBV transmission may be lower in endemic areas than in non-endemic areas, because most recipients have already been exposed to HBV. Blood safety for HBV, including OBI, has substantially improved, but the possibility for OBI transmission remains.

Sampled-data iterative learning control (SILC) for singular systems is addressed for the first time. With the introduction of the constrained relative degree, an SILC algorithm combined with a feedback control law is proposed for singular systems. Convergence of the algorithm is proved in sup-norm, while the conventional convergence analysis is in λ-norm. The final tracking error uniformly converges to a small residual set whose level of magnitude depends on the system dynamics and the sampling-period. Due to inequalities to estimate the level of the existing results of SILC, convergence is guaranteed not only at the sampling instants but on the entire operation interval, so that the inter-sample behavior is guaranteed, which is more practical for real implementation.

Context-awareness is becoming critical for mo- bile and ubiquitous computing, where the application needs dynamically adapt its behavior to its execution environment. Context-oriented programming （COP） languages support dy- namic behavior adaptation, however, they do not support dy- namic layer addition. As a result, they provide little support for the runtime adaptation of application behavior in case that unpredictable execution environments are encountered. Furthermore, block-structured constructs for layer activation hardly support fine-grain adaptation and separate changes of contexts and execution of context-specific methods with dif- ficulty. In this paper, we propose a virtual machine （VM）- centric approach to address these issues. It incorporates ob- ject composition and delegation into the VM to implement layer activation, and extends existing VM services to sup- port dynamic layer addition. To ensure that our approach preserves the type safety properties of the program, we de- velop a calculus built on featherweight Java （FJ） to describe the approach, focus on type-checking issues, and prove type soundness of the calculus. We also present the implementa- tion and evaluation of our approach. The evaluation demon- strates that our approach has advantages over the compiler- based approach proposed by JCOP.
