目的使用多层螺旋CT(multi-slice spiral computed tomography,MSCT)技术对高坠伤的损伤特征进行观察分析,并通过对高坠伤的分析和观察重建高坠过程,从而探讨MSCT在分析高坠伤案例中的应用价值。方法以真实的高坠伤案例为对象,分别运用MSCT平扫、三维重建技术对尸体进行全面检查,联合运用系统尸体解剖分析高坠伤死亡方式等特点,比较尸体解剖和MSCT在获取损伤信息方面的差异。结果MSCT扫描结合三维重建,发现全身多部位骨折以及肝破裂,尸体解剖与影像学检查结果相对应,推断死亡原因为高坠致全身多发伤。结论 MSCT在高坠伤案件致伤方式分析中可作为传统尸体解剖的补充手段。     

A CONSUMER-WELFARE APPROACH TO NETWORK NEUTRALITY REGULATION OF THE INTERNET

"Network neutrality" is the shorthand for a proposed regimeof economic regulation for the Internet. Because of the trendto deliver traditional telecommunications services, as wellas new forms of content and applications, by Internet protocol(IP), a regime of network neutrality regulation would displaceor subordinate a substantial portion of existing telecommunicationsregulation. If the United States adopts network neutrality regulation,other industrialized nations probably will soon follow. As aresult of their investment to create next-generation broadbandnetworks, network operators have the ability to innovate insidethe network by offering both senders and receivers of informationgreater bandwidth and prioritization of delivery. Network neutralityregulation would, among other things, prevent providers of broadbandInternet access service (such as digital subscriber line (DSL)or cable modem service) from offering a guaranteed, expediteddelivery speed in return for the payment of a fee. The practicaleffect of banning such differential pricing (called "accesstiering" by its critics) would be to prevent the pricing ofaccess to content or applications providers according to priorityof delivery. To the extent that an advertiser of a good or servicewould be willing to contract with a network operator for advertisingspace on the network operator's affiliated content, anotherpractical effect of network neutrality regulation would be toerect a barrier to vertical integration of network operatorsinto advertising-based business models that could supplementor replace revenues earned from their existing usage-based businessmodels. Moreover, by making end-users pay for the full costof broadband access, network neutrality regulation would denybroadband access to the large number of consumers who wouldnot be able to afford, or who would not have a willingness topay for, what would otherwise be less expensive access. Forexample, Google is planning to offer broadband access to end-usersfor free in San Francisco by charging other content providersfor advertising. This product offering is evidently predicatedon the belief that many end-users demand discounted or freebroadband access that is paid for by parties other than themselves.Proponents of network neutrality regulation argue that suchrestrictions on the pricing policies of network operators arenecessary to preserve innovation on the edges of the network,as opposed to innovation within the network. However, recognizingthat network congestion and real-time applications demand somedifferential pricing according to bandwidth or priority, proponentsof network neutrality regulation would allow broadband Internetaccess providers to charge higher prices to end-users (but notcontent or applications providers) who consume more bandwidthor who seek priority delivery of certain traffic. Thus, thedebate over network neutrality is essentially a debate overhow best to finance the construction and maintenance of a broadbandnetwork in a two-sided market in which senders and receivershave additive demand for the delivery of a given piece of information—andhence additive willingness to pay. Well-established tools ofRamsey pricing from regulatory economics can shed light on whethernetwork congestion and recovery of sunk investment in infrastructureare best addressed by charging providers of content and applications,broadband users, or both for expedited delivery. Apart fromthis pricing problem, an analytically simpler component of proposednetwork neutrality regulation would prohibit a network operatorfrom denying its users access to certain websites and Internetapplications, such as voice over Internet protocol (VoIP). Althoughsome instances of blocking of VoIP have been reported, suchconduct is not a serious risk to competition. To address thisconcern, I analyze whether market forces (that is, competitionamong access providers) and existing regulatory structures aresufficient to protect broadband users. I conclude that economicwelfare would be maximized by allowing access providers to differentiateservices vis-à-vis providers of content and applicationsin value-enhancing ways and by relying on existing legal regimesto protect consumers against the exercise of market power, shouldit exist.     

道路交通事故死者MSCT扫描与尸体解剖结果的比较

目的使用多层螺旋CT(MSCT)对道路交通事故中死者的损伤进行观察分析,探索MSCT在道路交通事故鉴定中的应用价值。方法对10例道路交通事故死亡者进行全身MSCT扫描,随后进行系统尸体解剖,并将两者的结果进行对比,分析两者在获取交通事故损伤信息方面的优点和不足。结果 MSCT可以清晰显示身体各部位骨折三维形态特征,并可检查到全身各部位的积气,相对于尸体解剖优势明显;但对于器官和软组织损伤的检测,MSCT的分辨率有限。结论对于道路交通事故死者,确定死亡方式和死亡原因的最好方法是联合进行MSCT检查和尸体解剖。     

The Internet,alternative public sphere and political dynamism: Korea's non-gaek * (polemist ) websites

Abstract

This paper explores the development of Korea's online alternative public sphere and illuminates the characteristics of this space, ‘activated’ by non-gaek websites. These websites host highly partisan discourses which are produced and disseminated by a focused political agenda that aims at political reform. Such a method of conducting discourse has led to the dissimilitude of the alternative public sphere, resulting in the birth of a multiplicity of spheres that represent divergent political views. This paper argues that although the overall extent of the alternative public sphere is expanded by non-gaek websites, it is becoming at the same time an exclusive and intolerant space. Furthermore, it is argued that to facilitate functional operation of the alternative public sphere, an institutionalization of rules and norms that can solve such problems is necessary.     

生产、销售伪劣产品罪新探

我国刑法第140条、146条和149条中的“产品”一词应改为“商品”,第140条和149条的罪名应确定为“生产、销售普通伪劣商品罪”。某些建设工程应纳入“伪劣产品”的范围,但需要在刑法第137条和第140条的法定刑之间进行平衡,即应加重前者的法定刑。如果只是单纯地假冒,不构成生产、销售伪劣产品罪,根据不同情况,或者只给予行政制裁,或者按假冒注册商标罪等犯罪论处。此外,生产销售伪劣产品罪还涉及到未遂形态、销售金额以及与相关条文的关系等问题。     

论所有权共有

一个所有权可以由两个或两个以上的人享有,所以有权的这一基本属性确立了共有这种数人同时享有同财产所有权的法律关系。对共有财产进行分割是我国民法研究的一个重要的课题,在对共有制度进行完善补充的时,加强对共有财产分割的立法思考尤为重要。

《监察法》实施中的若干问题与完善建议

我国《监察法》的正式颁布和顺利实施对于深入推进全面依法治国、有效促进反腐败法治化进程具有重要意义和重大影响。实地调研主要聚焦我国《监察法》实施中的四方面内容:监督权限制度、监察建议制度、监察赔偿制度和特约监察员制度。从国家监察体制改革法治化进程角度考量,应从以下途径予以完善:首先,建议明确监察机关的监督方式以及厘清内设机构的监督职权;其次,建议明确监察建议的基本内涵、主要内容和适用程序三方面内容;再次,建议明确监察赔偿的概念内涵、归责原则、构成要件与具体程序;最后,建议从国家立法层面制定专门的《特约监察员法》,统一规范特约监察员的选任条件、职责范围、职务保障等。     

163处肋骨骨折的影像学分析

目的：探讨影像学检查方法在不同区段肋骨骨折法医学鉴定中的应用。方法回顾性分析56例被鉴定人共计163处肋骨骨折的骨折部位、影像学检查次数及其首次检出的影像学技术等资料。结果在损伤后早期（≤14 d）的检出率为65.6%。 X线对肋骨前段骨折的首次检出率76.2%，两次内检出率90.5%；CT首次检出率66.7%，两次内检出率80.0%。 X线对肋骨腋段骨折的首次检出率仅27.6%，两次内检出率58.6%；CT首次检出率54.3%，两次内检出率80.4%。X线对肋骨背段骨折的首次检出率63.6%，两次内检出率81.8%；CT首次检出率50.0%，两次内检出率70.0%。结论在肋骨骨折的鉴定中，应注意影像学检查的随访，综合运用不同技术手段，尤其在疑有肋骨腋段骨折的案例中，单纯X线摄片可能造成漏检，建议选择CT扫描。
