“安全阀定律”与大城市交通问题探讨

近年来 ,随着城市化进程的加快 ,我国机动车拥有量及道路交通量急剧增加 ,已对城市交通造成严重压力。目前 ,我国几乎所有大中城市特别是100万人口以上的特大城市 ,都面临着交通拥挤、道路堵塞、事故增多、环境污染等诸多问题。据专家预计 ,在未来几十年内 ,以小汽车为背景的城市交通问题将有一个更大的发展 ,并将成为城市问题的第一号大难题。如果不从政策、投资、建设、管理和规划上认真加以考虑、解决 ,必将影响城市跨世纪的可持续发展 。

安全管理定律对临床麻醉安全管理方法构建的研究

目的分析临床麻醉安全管理中应用安全管理定律的作用。方法选取房县妇幼保健院药械科2019年1月—12月的792张麻醉药品处方进行研究,均采取安全管理定律进行管理,观察麻醉药品使用情况、麻醉药品用途合理性、麻醉药品问题发生率。结果792张麻醉药品处方中,5种注射剂利用指数均小于1.0,在合理用药范围内,用药基本合理;实施安全管理定律后,麻醉安全问题发生率逐渐降低。结论安全管理定律对临床麻醉安全管理方法构建有着重要作用,能够提高麻醉药品管理效率,同时降低麻醉安全问题,值得推广。

安全管理定律对临床麻醉安全管理方法构建的价值

目的:探讨安全管理定律对医院临床麻醉安全管理方法构建的价值和意义。方法:选择2018年2月~2019年2月期间在医院就医并接受麻醉治疗的300名患者为研究对象,根据入院先后顺序分为观察组和对照组。对照组患者住院治疗期间采用常规安全管理,观察组从安全管理定律出发构建临床麻醉安全管理方法。统计并比较两组患者接受治疗期间麻醉相关风险事件的发生率及麻醉药品重复登记、麻醉药品破损、麻醉药品登记数量与使用数量不符、麻醉药品管理差错的发生率。结果:观察组风险事件总发生率低于对照组(P<0.05)。观察组麻醉药品相关风险事件的发生率低于对照组(P<0.05)。结论:安全管理定律有助于提高麻醉安全管理质量,降低了临床麻醉相关风险事件的发生率。

从安全管理定律角度构建医院麻醉安全文化

目的:探讨从安全管理定律角度构建临床麻醉管理方法的价值。方法:随机选择2017年6月~2019年5月使用麻醉药品进行手术的患者250例为研究对象,随机均分为对照组与观察组,对照组采用传统的麻醉管理方式,观察组从安全管理定律的角度优化现有的麻醉科管理方法。比较两组患者对麻醉管理质量的评分及不良事件发生率。结果:观察组患者管理后对科室环境管理、麻醉药品管理、业务水平管理、不良事件管理等评分,均显著高于管理前及对照组管理后(P<0.05)。观察组患者的药物选择不适宜、药物重复使用、药物剂型不适宜、药物剂量选择不适宜、给药频次不适宜等发生率,均显著低于对照组(P<0.05)。结论:从安全管理定律角度构建医院麻醉管理方法,有助于提升医院麻醉管理质量,提升安全管理系数。

Japanese Social Mentality and the Change in the Approval Rates of the Abe Administration

From June to July of 2017, the approval rates of the Abe administration fell sharply, in stark contrast to the long-term stability since 2012. The stability of Abe＇ s approval rates originated from the people＇ s negative support for him and their opposition to the Security Laws and other important events as well as the scandals under his administration. The opposition and negative support originated from the people＇s ＂acquired helplessness＂, ＂Abenomics＂, the sharp drop in the opporttmity costs of voting and other conditions. The sudden fall of Abe＇ s approval rates was not due to the change in the aforementioned conditions, rather because of the collapse of his image including personality owing to Abe＇ s perceived arrogance and his estrangement with the people. In the context of the temporary stabilization of approval rates, Abe dissolved the House of Representatives ahead of schedule and held a general election, taking full advantage of the internal strife between the opposition parties, to achieve his goal of ruling until the 2020 Tokyo Olympics. His victory in the recent election does not accurately demonstrate that Abe is completely immune to negative impact, thus he will to use the Korean Peninsula crisis and other issues to demonstrate his ability of safeguarding Japan＇s security, seek reconstruction of his image, and further enhance his approval rate to stabilize his administration.

Seat belt use during pregnancy in Iran： attitudes and practices

Objective： Seat belt use during pregnancy reduces injury to the mother and her fetus. During recent years, the use of seat belts has been mandated by law in Iran. The purpose of this study was to determine the attitudes and practices of pregnant women regarding seat belt use. Methods： In this cross-sectional study, we asked 335 pregnant women at a hospital-based prenatal care clinic on the use of safety belt before and during pregnancy. SPSS version 13.0 was used for data analysis. Results： The mean age of study subjects was 27.3 years±5.3 years with the median of 27 years. Compared with the seat belt use before pregnancy, no change was detectedin 48.7% of the women; seat belt use had increased in 17.5 % of them and decreased in 33.8 %. Eighty-one percent of women knew the correct placing ＆both lap belt and shoulder belt. Only 4% of women had received education on proper restraint use during pregnancy. Conclusions： The prevalence of seat belt use during pregnancy is lower than reports which are mostly from developed nations. The fact that about one-third of women have decreased their seat belt usage during pregnancy highlights the importance of education of mothers on this topic.
