简介：摘要:目前，我国大力倡导“大众创业、万众创新”，鼓励创新型产业发展，随着我国人民对具有文化内涵的创新型产品和服务需求量的不断增长，从而推动了大批文化创意企业的创立和发展。然而，大部分文化创意企业目前处于发展的萌芽阶段，管理层防范风的险意识比较薄弱。因此，对于处于高风险区域的文化创意企业来说，运用合理的风险管理方法来规避风险，对于企业实现战略经营目标意义非凡。

简介：AbstractTrauma-induced pulmonary thromboembolism is the second leading cause of death in severe trauma patients. Primary fibrinolytic hyperactivity combined with hemorrhage and consequential hypercoagulability in severe trauma patients create a huge challenge for clinicians. It is crucial to ensure a safe anticoagulant therapy for trauma patients, but a series of clinical issues need to be answered first, for example, what are the risk factors for traumatic venous thromboembolism? How to assess and determine the status of coagulation dysfunction of patients? When is the optimal timing to initiate pharmacologic prophylaxis for venous thromboembolism? What types of prophylactic agents should be used? How to manage the anticoagulation-related hemorrhage and to determine the optimal timing of restarting chemoprophylaxis? The present review attempts to answer the above questions.

简介：AbstractBackground:Cerebrovascular disease has become the leading cause of death in China. The purpose of this article is to analyze China's contribution to the interventional treatment of cerebrovascular diseases.Methods:Bibliometric analysis was used for evaluating the quantity, quality, research hotspots, and cooperation network of publications regarding interventional treatment of cerebrovascular diseases from China. These articles were searched from the database of Web of Science Core Collection. The authors, publication years, citation times, regions, and source journals of retrieved articles were recorded. Network analysis and visualization were performed on Citespace5.6.Results:From 1991 to 2019, a total of 5052 articles regarding cerebrovascular intervention were contributed by Chinese researchers. The number of publications from China grew fastest annually in the latest 5 years among countries. These publications were cited 61,216 times, with 12.12 average citations per item. The h-index was 82. Affiliated hospitals of Capital Medical University contributed most articles. Cerebral ischemia and intracranial aneurysm were the most popular keywords over the three decades. The timeline view of keywords indicated that cerebral ischemia always was a hot spot. Stent techniques were the main treatment tools and still had a strong developing trend. Neural regeneration and neuroprotection were the hot topics of basic researches related to cerebrovascular intervention.Conclusions:The number of researches grows rapidly in China over the decades, but the quality still needs further improvement. The increasing contributions of Chinese researchers to the global knowledge system of cerebrovascular intervention are promising.

简介：摘要：在目标识别领域的数据融合技术当中，D-S证据理论被广泛应用，主要在于D-S证据理论可以有效的处理不确定信息。可有效处理复杂环境下引起的不确定问题，使其处理不确定信息时更加的高效。其缺点是在高冲突的证据发生时，得不到有效结果。本研究为探寻一种能够优化证据理论的方法，使其达到高冲突证据环境中，还能得到不偏离现实的有效融合结果的目的，研究并整理了大量相关文献，研究过程中发现有学者针对此方向有过探究，但效果不甚理想。基于此，本文经查阅大量国内外相关文献，为探寻一种解决高冲突证据问题的方法后分析和整理成为本篇综述。
