英汉“恐惧”隐喻的对比分析

情感是人类最普遍、最重要的人生体验。而“恐惧”情感这一抽象的概念常常是用隐喻来表达的。英汉两种语言中都有大量表达“恐惧”情感的隐喻,存在着共性,这源于人类相同的生理特征和情感体验,但是英汉语言中也存在不对应的概念隐喻,这源于各自不同的文化模式.     

Is right ventricular mid-septal pacing superior to apical pacing in patients with high degree atrio-ventricular block and moderately depressed left ventricular function?

Objective

We are aimed to investigate whether right ventricular mid-septal pacing (RVMSP) is superior to conventional right ventricular apical pacing (RVAP) in improving clinical functional capacity and left ventricular ejection fraction (LVEF) for patients with high-degree atrio-ventricular block and moderately depressed left ventricle (LV) function.

Methods

Ninety-two patients with high-degree atrio-ventricular block and moderately reduced LVEF (ranging from 35% to 50%) were randomly allocated to RVMSP (n=45) and RVAP (n=47). New York Heart Association (NYHA) functional class, echocardiographic LVEF, and distance during a 6-min walk test (6MWT) were determined at 18 months after pacemaker implantation. Serum levels of N-terminal pro-brain natriuretic peptide (NT-proBNP) were measured using an enzyme-linked immunosorbent assay (ELISA) kit.

Results

Compared with baseline, NYHA functional class remained unchanged at 18 months, distance during 6MWT (485 m vs. 517 m) and LVEF (36.7% vs. 41.8%) were increased, but BNP levels were reduced (2352 pg/ml vs. 710 pg/ml) in the RVMSP group compared with those in the RVAP group, especially in patients with LVEF 35%–40% (for all comparisons, P<0.05). However, clinical function capacity and LV function measurements were not significantly changed in patients with RVAP, despite the pacing measurements being similar in both groups, such as R-wave amplitude and capture threshold.

Conclusions

RVMSP provides a better clinical utility, compared with RVAP, in patients with high-degree atrioventricular block and moderately depressed LV function whose LVEF levels ranged from 35% to 40%.     

Five Systematic Transformations and Their Impacts on Academic Profession in China

Abstract:

The dynamism of contemporary Chinese society reflects itself in higher education and the academic profession. The remarkable changes in the past 30 years include the shifting from a planned system to a market system on one hand, and the shifting from a closed system to an open system on the other hand. Five obvious transformations in higher education resulted from this social dynamism. They are identified as massification, decentralization, marketization, differentiation, and internationalization respectively. Such a dynamic context has complicated the scenario for the Chinese academic profession.

The Use of Augmented Reality Technology in Medical Specimen Museum Tours

Human anatomical specimen museums are commonly used by medical, nursing, and paramedical students. Through dissection and prosection, the specimens housed in these museums allow students to appreciate the complex relationships of organs and structures in more detail than textbooks could provide. However, it may be difficult for students, particularly novices, to identify the various parts of these anatomical structures without additional explanations from a docent or supplemental illustrations. Recently, augmented reality (AR) has been used in many museum exhibits to display virtual objects in videos captured from the real world. This technology can significantly enhance the learning experience. In this study, three AR-based support systems for tours in medical specimen museums were developed, and their usability and effectiveness for learning were examined. The first system was constructed using an AR marker. This system could display virtual label information for specimens by capturing AR markers using a tablet camera. Individual AR markers were required for all specimens, but their presence in and on the prosected specimens could also be obtrusive. The second system was developed to set the specimen image itself as an image marker, as most specimens were displayed in cross section. Visitors could then obtain the label information presented by AR without any markers intruding on the display or anatomical specimens. The third system was comprised of a head-mounted display combined with a natural click interface. The system could provide visitors with an environment for the natural manipulation of virtual objects with future scalability.     

面向产业创新升级的企业规模质量：概念界定、量表开发及检验

有利于产业创新升级的企业成长模式一直是研究热点问题。本文将我国产业创新升级普遍存在的低产业化、大而不强和传统产业升级抽象为企业规模阈值问题,并通过对三种规模阈值的突破引入和界定了企业规模质量的概念范畴。以此为基础并结合文献分析法,本文提出构成企业规模质量的R&D投入、非R&D投入和知识能量3个维度及11个能力要素,通过预测试、问卷调查等方式进一步实证检验了量表的可靠性和有效性,得出了有助于推动产业创新升级的企业规模质量量表工具。在量表工具下本文提出了针对技术创新和产业升级的对策建议。
