（三） 　　背景资料 　　某施工单位承接一高层建筑的泛光照明工程。建筑高度为180m，有3个透空段，建筑结构已完工，外幕墙正在施工。泛光照明由LED灯（55W）和金卤灯（400W）组成。LED灯（连支架重100kg）安装在幕墙上，金卤灯安装在透空段平台上，由控制模块（256路）进行场景控制。施工单位依据合同、施工图、规范和幕墙施工进度计划等编制了泛光照明的施工方案，施工进度计划见表1（细实线），劳动力计划见表2． 　　方案中LED灯具的安装，选用吊篮施工，吊篮尺寸为6000×450×1180mm，牵引电动机功率为1.5KW×2，提升速度为9.6m/min，载重630kg（载人2名）。按进度计划，共租赁4台吊篮。 　　因工程变化，建筑幕墙4月底竣工，LED灯具的安装不能按原进度计划实施，施工单位对LED灯和金卤灯的安装计划进行了调整，见表1（粗实线）。调整后的LED灯安装需租赁6台吊篮，作业人员增加到24人，施工单位又编制了临时用电施工组织设计。

吊篮施工方案中应制订哪些安全技术措施和主要的应急预案？

Large parts of the world have not enjoyed the remarkable global progress in health conditions that have taken place over the past century. Indeed, millions of deaths in impoverished nations are avoidable with prevention and treatment options that the rich world already uses. This year, 10 million children will die in low and middle income countries. If child death rates were the same as those in developed countries this figure would be lower than 1 million. Conversely, if child death rates were those of rich countries just 100 years ago, the figure would be 30 million. Today’s tools for improving health are so powerful and inexpensive that health conditions could be reasonably good even in poor countries if policy makers spent even relatively little in the right places.

Recent research for the Copenhagen Consensus identifies several highly cost-effective options that would tackle some of the planet’s most urgent health problems. The most promising investment is in tuberculosis treatment. Some 90 percent of the 1.6 million tuberculosis deaths in 2003 occurred in low-and middle-income countries. Because tuberculosis affects working-age people, it can be a trigger of household poverty. The cornerstone of control is prompt treatment using first-line drugs, which doesn’t require a sophisticated health system. Spending $1 billion on tuberculosis treatment in a year would save 1 million lives. Because good health accompanies higher levels of national economic welfare in the long run, the economic benefits are worth $ 30 billion.

The second most cost-effective investment is tackling heart disease. Heart disease might not seem like a pressing issue for poor nations, but it represents more than a quarter of their death toll. Measures to reduce risk factors other than smoking — high intake or saturated animal fat, obesity, binge drinking of. alcohol, physical inactivity, and low fruit and vegetable consumption — have had little success. Treating acute heart attacks with inexpensive drugs is, however, cost-effective. Spending $ 200 million could avert several hundred thousand deaths, yielding benefits that are 25 times higher than costs.

The third option is prevention and treatment of malaria. A billion dollars would expand the provision of insecticide-treated bed-nets and facilitate provision of highly effective treatment. This would save more than a million child deaths and produce economic benefits worth $ 20 billion.

The fourth alternative for policymakers is to focus on child health initiatives. The best measures are familiar ones expanding immunization coverage, promoting breastfeeding, increasing the use of simple and cheap treatments for diarrhea and childhood pneumonia, and so on.

Even if the costs of all these initiatives were two or three times higher than we estimate, these efforts would still provide amazing opportunities to reduce health inequality and do good in the world.

Over the past century, the child death rates have（）.

A．climbed steadily in impoverished countries

B．dropped remarkably in developed countries

C．fluctuated wildly in low-income countries

D．remained stable in middle-income countries
