Evolution of working conditions under the impact of ICTs

IntroductionInformation and communication technologies (ICTs) play a major role in the current evolution of work. They are both a great tool for emancipating human beings from the most tedious and most dangerous tasks and an effective vector for intensifying work.MethodsOn the basis of three foresight exercises carried out in recent years and by describing concrete examples of work organizations, the authors highlight the main possible trends for the changes to come.ConclusionsThey conclude on a few general principles that could allow the establishment of a win–win policy.     

Cycle Aware: Piloting a module for novice drivers

Introduction: In low-cycling countries, motor-vehicle traffic and driver behavior are well known barriers to the uptake of bicycles, particularly for utility cycling. Lack of separation between cyclists and faster-moving traffic is one key issue, while attitudes of drivers toward and/or harassment of cyclists is another. Cyclist-related driver education has been recommended as a means to improve driver-cyclist interactions. Methods: The driver licensing process provides an opportunity for such education. The Cycle Aware module was developed to test and enhance novice drivers’ knowledge of interacting safely with cyclists. It was piloted across three Australian jurisdictions targeting both novice and experienced drivers. Participants were asked to complete the Cycle Aware module and an accompanying survey. A total of 134 novice and 97 experienced drivers completed the survey with 42 novice and 50 experienced drivers going on to complete the module. Results: Both groups of drivers scored equally well in the module but the very youngest and very oldest participants were more likely to have some incorrect responses. We did not find any relationship between correct module scores and attitudes toward cyclists. Survey results showed both novice and experienced drivers had somewhat positive attitudes toward cyclists. The two cohorts differed on several attitude questions. Sixty percent (60%) of novices compared to 30% of experienced drivers reported feeling concerned when sharing the road with cyclists, and novices were less likely to agree that cyclists had a right to use the roads. Conclusions and practical applications: The analysis suggests novices need to be better equipped to share roads confidently with cyclists and to recognize cyclists as legitimate traffic participants.     

Review of hydrogen safety during storage,transmission, and applications processes

Hydrogen is considered an excellent clean fuel with potential applications in several fields. There are serious safety concerns associated with the hydrogen process. These concerns need to be thoroughly understood and addressed to ensure its safe operation. To better understand the safety challenges of hydrogen use, application, and process, it is essential to undertake a detailed risk analysis. This can be achieved by performing detailed consequence modellings and assessing risk using the computational fluid dynamics (CFD) approach. This study comprehensively reviews and analyses safety challenges related to hydrogen, focusing on hydrogen storage, transmission, and application processes. Range of release and dispersion scenarios are investigated to analyse associated hazards. Approaches to quantitative risk assessment are also briefly discussed.     

基于模糊层次分析法的木结构古建筑安全评价

为准确地对木结构古建筑进行安全现状评价,考虑到木结构古建筑的结构复杂性,本文提出一种基于模糊层次分析法的木结构古建筑评价方法。利用该方法对故宫博物院景福宫进行检测和评价。结果表明:利用层次分析法对木结构古建筑进行安全性评价简单可行,与传统的评级法相比,该方法可考虑不同构件对结构安全性的贡献程度以及不同属性对同一构件安全性的贡献程度,提高了木结构古建筑安全评价的准确性和可靠性。
