中日韩FTA对产业的影响分析

随着中、日、韩贸易投资合作日益密切,区域内贸易和产业内贸易不断增加,三国关于建立自由贸易区的讨论日益激烈。分析比较三国产业竞争力,可以看到我国的整体产业竞争力与韩日相差较大,处于三国垂直型产业内贸易分工结构的低端。在这一背景下缔结三国FTA,我国的主要产业和相关企业短期内会受到一定冲击,但长远看可以促进我国产业结构升级,提高产业竞争力。为对应中日韩FTA,我国政府应改善产业环境,放宽市场限制,建立公正公平的市场机制。企业需要适应贸易投资环境的变化,从技术创新、产品差异化和管理与营销等方面加强与竞争对手的抗衡能力。     

我国应当尽快确立电子商务证据的法律地位

随着电子商务的普及推广,电子商务证据与现行法律规定发生冲突,已在司法实践中显现出来。在我国,这种冲突主要体现在电子商务证据的种类、形式等方面,借鉴世界各国和国际社会的不同做法,我国应对其合法地位作出相应的法律规定,以适应电子商务发展的需要。     

略论高科技对电影文化的影响

进入90年代以来，以数字化为代表的电影艺术的技术性革命对电影化产生至关重要的影响。电影本体、电影机制、影像的美学意义、电影接受心理等理论课题都必须放置在崭新的技术语境中讨论才有意义。面对日新月异的数字化技术的迅速发展，我们既要考虑到以数字化技术为代表的科技发展对电影的促进作用，又要清醒地认识到高科技对电影艺术的负面影响，从而完成电影化对物质化的整合和超越。

Monopoly defeating mechanisms: Will they function in the digital world?

History reveals that ‘copyright’ was originally monopolistic (in the early fifteenth century) and remained so until the enactment of the Statute of Anne in 1709. Since then copyright has striven to maintain a delicate balance between incentive to authors and avoiding monopolistic stagnation. To achieve these goals, certain monopoly-defeating mechanisms have been adopted such as: fair use, public domain, the idea/expression dichotomy and the exhaustion doctrine. Recently, however, with the implementation of new laws: for instance the Digital Millennium Copyright Act (1988), the EU Copyright Directive (2001), and the implementation of the EU Copyright and Related Rights Regulation amending the Copyright, Design and Patents Act 1988, there is a growing concern that the mechanisms which were enacted to defeat the monopoly will not work in the digital medium. With the provision of affixing technological measures to copyrighted works and the non-application of the exhaustion doctrine in the digital world, arguably the monopoly defeating mechanisms have been disabled. The aim of this paper is to demonstrate the way monopoly defeating mechanisms are becoming non-functional in the digital world. Furthermore, the study also demonstrates how the European Copyright Directive and the UK implementation of the Directive has transgressed the boundary of exclusive rights set by the two World Intellectual Property Organization (WIPO) treaties – the World Copyright Treaty (WCT) and the WIPO Performers and Phonograms Treaty (WPPT) – and copyright law, thereby strengthening the copyright owner's rights in a way that was never intended by the WIPO treaties or by copyright law. Consequently, the new laws have also shifted copyright's attention from commercial pirates to non-commercial individual users. The study aims to demonstrate how the shift took place and finally, trace the recurrence of the monopoly; giving rise to a situation where there is no fair use/dealing, no public domain, no idea/expression distinction and no exhaustion doctrine.     

Reduction of postmortem angiography-induced tissue edema by using polyethylene glycol as a contrast agent dissolver

Postmortem investigation is increasingly supported by computed tomography (CT) and magnetic resonance imaging, in which postmortem minimal invasive angiography has become important. The newly introduced approach using an aqueous contrast agent solution provided excellent vessel visualization but was suspected to possibly cause tissue edema artifacts in histological investigations. The aim of this study was to investigate on a porcine heart model whether it is possible to influence the contrast agent distribution within the soft tissue by changing its viscosity by dissolving the contrast agent in polyethylene glycol (PEG) as a matrix medium. High-resolution CT scans after injection showed that viscosities above c. 15 mPa s (65% PEG) prevented a contrast agent distribution within the capillary bed of the left ventricular myocardium. Thereby, the precondition of edema artifacts could be reduced. Its minimal invasive application on human corpses needs to be further adapted as the flow resistance is expected to differ between different tissues.

Using anisotropic diffusion for efficient extraction of sensor noise in camera identification

Each digital camera has an intrinsic fingerprint that is unique to each camera. This device fingerprint can be extracted from an image and can be compared with a reference device fingerprint to determine the device origin. The complexity of the filters proposed to accomplish this is increasing. In this note, we use a relatively simple algorithm to extract the sensor noise from images. It has the advantages of being easy to implement and parallelize, and working faster than the wavelet filter that is common for this application. In addition, we compare the performance with a simple median filter and assess whether a previously proposed fingerprint enhancement technique improves results. Experiments are performed on approximately 7500 images originating from 69 cameras, and the results are compared with this often used wavelet filter. Despite the simplicity of the proposed method, the performance exceeds the common wavelet filter and reduces the time needed for the extraction.
