浅谈道路桥梁路基施工

路基是公路的重要组成部分,是按照路线位置和一定技术要求修筑的带状构造物,承受由路面传来的荷载,应有足够的强度、稳定性和耐久性。本文根据已有的经验,对当前如何保证以最佳的效果解决好公路路基施工技术问题加以研究,使我国的公路建设再上一个新台阶。     

Seat-belt use still low in Kuwait: self-reported driving behaviours among adult drivers

Kuwait mandated seat-belt use by drivers in 1976 and by front seat passengers in 1994. The study objectives were to identify and estimate current factors associated with seat-belt use and levels of potentially unsafe driving behaviours in Kuwait. In 2010, 741 adults were surveyed regarding driving habits and history. Only 41.6% of drivers reported always using a seat belt. Front seat passenger belt use was more common (30.5%) than rear seat belt use (6.5%). Distracted driving behaviours were common, including mobile phone use (‘always’ or ‘almost always’: 51.1%) and texting/SMS (32.4%). Logistic regression indicated that drivers who were young (18–19 years), male, Kuwaiti nationals or non-Kuwaiti Arabs, drove over the speed limit, had traffic violation tickets or >1 car crashes in the last year, were less likely to use seat belts. Targeted initiatives to increase public awareness and to enforce car-safety legislation, including use of seat belts, are necessary to decrease the health burden of car crashes in Kuwait.     

Knowledge,beliefs and attitudes of squash venue operators relating to use of protective eyewear

Sports venues are in a position to potentially influence the safety practices of their patrons. This study examined the knowledge, beliefs and attitudes of venue operators that could influence the use of protective eyewear by squash players. A 50% random sample of all private and public squash venues affiliated with the Victorian Squash Federation in metropolitan Melbourne was selected. Face-to-face interviews were conducted with 15 squash venue operators during August 2001. Interviews were transcribed and content and thematic analyses were performed. The content of the interviews covered five topics: (1) overall injury risk perception, (2) eye injury occurrence, (3) knowledge, behaviors, attitudes and beliefs associated with protective eyewear, (4) compulsory protective eyewear and (5) availability of protective eyewear at venues. Venue operators were mainly concerned with the severe nature of eye injuries, rather than the relatively low incidence of these injuries. Some venue operators believed that players should wear any eyewear, rather than none at all, and believed that more players should use protective eyewear. Generally, they did not believe that players with higher levels of experience and expertise needed to wear protective eyewear when playing. Only six venues had at least one type of eyewear available for players to hire or borrow or to purchase. Operators expressed a desire to be informed about correct protective eyewear. Appropriate protective eyewear is not readily available at squash venues. Better-informed venue operators may be more likely to provide suitable protective eyewear.

浅谈影响公路工程质量的因素以及应对策略

工程建设是一个系统,影响工程质量的因素很多,上级政策、技术规范、决策思想、施工工艺、管理水平、工作质量及设计、施工、监理、业主、监督各单位的建设行为等因素都与工程质量密切相关。本文就几个主要原因进行分析,给出一些在公路路基建设阶段应该加强质量的措施。     

浅析公路施工中网络技术的应用

目前我国的网络计划技术在应用管理上,特别是计划执行中的监督与控制以及跟踪调整方面比较落后,基本上停留在计划的编制上。如何在施工管理中提高网络计划技术的应用水平是本文所要讨论的问题。     

List of Reviewers 2013

Motor vehicle accidents are the leading cause of death in adolescents and young adults worldwide. Nearly three-quarters of road deaths occur in developing countries and men comprise a mean 80% of casualties. The rate of road traffic accidents caused by four-wheeled vehicles is the highest globally reported road traffic accidents statistic. In Saudi Arabia, the motor vehicle is the main means of transportation with one person killed and four injured every hour. Over 65% of accidents occur because of vehicles travelling at excess speed and/or drivers disobeying traffic signals. Road traffic injuries cause considerable economic losses to victims, their families, and to nations as a whole. Strategic prevention plans should be implemented soon by various sectors (health, police, transport, and education) to decrease the mortality and morbidity among adolescent and young age group. Strong and effective coordination between ministry of health and other ministries together with World Health Organization and other related organisations will be an important step towards implementing the international Decade of Action for Road Safety (2011–2020). The aim of this review article is to highlight some aspects of the health impacts of road traffic accidents.     

城市干道交通拥堵识别技术研究

为快速有效地进行城市干道的交通拥堵识别,文中提出一种基于朴素贝叶斯的城市干道交通拥堵识别算法。最后,基于南京市主干道的交通调查数据,对朴素贝叶斯算法以及基于径向基函数神经网络的城市干道交通拥堵识别算法进行对比。结果表明,朴素贝叶斯算法在对城市干道交通状态的识别上比基于径向基函数神经网络算法具有更好的准确性、优越性以及更低的误判率。
