工程建设施工现场中3G视频监控系统的研究与实现

随着建筑行业的飞速发展,施工现场的安全问题一直是工地管理工作的重中之重。网络技术的发展,使得视频监控系统运用到各行各业中。通过运用远程视频监控技术,实时对分布在各地的多个施工现场进行监管,既减轻了管理人员的工作量,又加强了建设行政主管部门以及施工和安全质量监督管理部门的监管力度。安全管理是建筑工地的重要管理环节,考虑到工地实际需求,本文针对传统视频监控系统实时性差、传输效率低、图像质量不稳定等缺点,对基于3G网络的工程建设施工现场远程视频监控系统进行研究和实现。文中介绍了3G网络的无线视频技术的优势及远程视频监控系统的功能特点,对施工现场3G远程视频监控系统的方案进行研究设计,并在某施工单位几个重点施工现场进行了试点安装,达到了预期效果,实现对施工现场实时监控。     

Long-term health economic benefits of sensor-augmented pump therapy vs continuous subcutaneous insulin infusion alone in type 1 diabetes: a UK perspective

Aims/hypothesis:

Continuous subcutaneous insulin infusion (CSII) is an important treatment option for type 1 diabetes patients unable to achieve adequate glycemic control with multiple daily injections (MDI). Combining CSII with continuous glucose monitoring (CGM) in sensor-augmented pump therapy (SAP) with a low glucose-suspend (LGS) feature may further improve glycemic control and reduce the frequency of hypoglycemia. A cost-effectiveness analysis of SAP?+?LGS vs CSII plus self-monitoring of blood glucose (SMBG) was performed to determine the health economic benefits of SAP?+?LGS in type 1 diabetes patients using CSII in the UK.

Methods:

Cost-effectiveness analysis was performed using the CORE diabetes model. Treatment effects were sourced from the literature, where SAP?+?LGS was associated with a projected HbA_1c reduction of ?1.49% vs ?0.62% for CSII, and a reduced frequency of severe hypoglycemia. The time horizon was that of patient lifetimes; future costs and clinical outcomes were discounted at 3.5% and 1.5% per annum, respectively.

Results:

Projected outcomes showed that SAP?+?LGS was associated with higher mean quality-adjusted life expectancy (17.9 vs 14.9 quality-adjusted life years [QALYs], SAP?+?LGS vs CSII), and higher life expectancy (23.8 vs 21.9 years), but higher mean lifetime direct costs (GBP 125,559 vs GBP 88,991), leading to an incremental cost-effectiveness ratio (ICER) of GBP 12,233 per QALY gained for SAP?+?LGS vs CSII. Findings of the base-case analysis remained robust in sensitivity analyses.

Conclusions/interpretation:

For UK-based type 1 diabetes patients with poor glycemic control, the use of SAP?+?LGS is likely to be cost-effective compared with CSII plus SMBG.

Effects of Ownership Structure on Capital Structure of Indian Listed Firms: Role of Business Groups vis-à-vis Stand-Alone Firms

The objective of this study was to explore the relationship between promoter ownership and capital structure of firms’ using a sample of Indian publicly listed firms for the period from 2006 to 2013. We find that the relationship between promoter ownership and leverage is inversely U-shaped in group-affiliated firms, whereas in stand-alone firms there is a U-shaped relationship. We argue that a substantial presence of family owners and the selection of managers from within the family play some role for such relationship in group-affiliated firms. On the other hand, the argument for observed relationship in stand-alone firms follows from alignment hypothesis, entrenchment hypothesis, managerial risk aversion hypothesis, and active monitoring hypothesis.     

106例药品不良反应报告分析

目的：探讨患者发生药品不良反应（ADR）的特点,加强ADR监测,促进临床合理用药。方法收集惠州市中医医院2014年通过广东省药品不良反应管理平台报告ADR监测网的106例ADR报告,对患者的年龄、性别、给药途径、药物联用情况、ADR累及器官或系统及临床表现等方面进行分类统计和分析。结果106例ADR报告中,患者年龄最小3岁,最大85岁,其中以大于50岁的患者居多,共57例,占53.7%;发生ADR患者的主要给药途径为静脉滴注;涉及药品共9类,以使用抗感染药品出现ADR最多见,中药制剂次之;两药联用最多见,占51.9%;主要以皮肤及其附件损伤为主,共27例,占25.5%;消化系统、神经系统次之;治疗后56例患者治愈,50例好转。结论由于ADR的发生与多种因素相关,存在一定的不可预见性,因此临床需提高对ADR的重视程度,加强对ADR的监测与报告,减少ADR的发生,保障临床用药安全。
