浅谈定向运动在我国开展的前景

风靡欧洲、北美及亚洲部分地区的定向运动越来越受到世人的关注。本文对定向运动进行了简介 ,并就定向运动在我国开展的前景进行了分析 ,提出开展和普及定向运动的具体建议     

丽江古城

丽江纳西族自治县地处滇西北的中部，青藏高原的东南边缘，金沙江上游。县城丽江古城海拔2，400米，面积约3．8平方公里，始建于南宋末年，盛于明清，一直是滇西北政治、军事、经济和文化重镇。1997年12月，丽江古城被联合国教科文组织列入《世界遗产名录》。

Dose requirements of continuous infusion of rocuronium and atracurium throughout orthotopic liver transplantation in humans

Objective: To compare the dose requirements of continuous infusion of rocuronium and atracurium throughout orthotopic liver transplantation (OLT) in humans. Methods: Twenty male patients undergoing liver transplantation were randomly assigned to two comparable groups of 10 patients each to receive a continuous infusion of rocuronium or atracurium under intravenous balanced anesthesia. The response of adductor pollicis to train-of-four (TOF) stimulation of unlar nerve was monitored. The infusion rates of rocuronium and atracurium were adjusted to maintain T1/Tc ratio of 2%–10%. The total dose of each drug given during each of the three phases of OLT was recorded. Results: Rocuronium requirement, which were (0.468±0.167) mg/(kg·h) during the paleohepatic phase, decreased significantly during the anhepatic phase to (0.303±0.134) mg/(kg·h) and returned to the initial values at the neohepatic period ((0.429±0.130) mg/(kg·h)); whereas atracuruim requirements remained unchanged during orthotopic liver transplantation. Conclusions: This study showed that the exclusion of the liver from the circulation results in the significantly reduced requirement of rocuronium while the requirement of atracurium was not changed, which suggests that the liver is of major importance in the clearance of rocuronium. A continuous infusion of atracurium with constant rate can provide stable neuromuscular blockade during the three stages of OLT.     

论我国劳动保障法律体系的建立与完善

在就业格局发生重大变化、劳动关系日趋复杂化的今天,劳动保障法律法规体系的"空白"逐渐显现。国内用工体制改革不断深化,劳动力市场逐步发育生成,雇主与雇工建立于法律基础之上的劳动契约关系,日益成为国内劳动就业关系的主流形态。与此相伴,劳资矛盾也日趋加剧和激化,我国劳动保障法制建设存在一定问题和不足。     

课程开发的规范化与技术标准建设

实现基于制度而不是协商结果的、真正意义上的学历教育与职业培训相互沟通，实现高水平的双证书管理和实施双证书课程，需要制定课程开发的技术标准，在职业活动、学习内容、教学设计、教学实施以及职业资格鉴定之间建立畅通、和谐的关系。谊技术标准应能对课程开发各个环节的工作方式和质量控制过程进行规范，标准的制定要实现方法论的转折，并具有一定的开放性。     

论中小学教师继续教育的实效性

随着素质教育的全面推进,中小学教师继续教育显得日趋紧迫,必须从课程开发、培训方式、教学管理考核方式等一系列环节抓出成效,真正全面提高中小学教师的专业素质。

Sensitivity analyses of cables to suspen-dome structural system

The construction of the cables is a key step for erecting suspen-dome structures. In practical engineering, it is difficult to ensure that the designed pre-stresses of cables have been exactly introduced into the structures in the site; so it is necessary to evaluate the influence of the variation of the pre-stresses on the structural behavior. In the present work, an orthogonal design method was employed to investigate the pre-stressed cables'sensitivity to the suspen-dome system. The investigation was concentrated on a Kiewitt suspen-dome. Parametric studies were carried out to study the sensitivity of the structure's static behavior, dynamic behavior, and buckling loads when the pre-stresses in the cables varied. The investigation indicated that suspen-dome structures are sensitive to the pre-stresses in all cables; and that the sensitivity depended on the location of the cables and the kind of structural behavior. Useful suggestions are given at the end of the paper.
