广州市河涌水质监测信息发布实例及思考

广州市于2013年6月起每月对外发布50条主要河涌的水质监测信息。该项工作在满足公众环境知情权,加强公众参与和公众监督,为政府河涌综合整治工作提供决策依据,促进水环境质量改善等方面发挥了积极作用。本文着重介绍了广州市河涌水质监测信息发布中面临的问题、发布实例和几点思考,为此类工作提供经验借鉴。     

培养应用型油气储运人才的信息化教学探索

结合北部湾地区对油气储运人才的需求,以培养服务地方的应用型油气储运人才为目标,对培养油气储运人才的基础化学教学过程进行了改革。通过将信息化教法和信息化学法引入课堂教学,不仅可以更加高效的对知识体系进行优化整合,而且教学过程更加生动有趣,有利于提高学生自主学习的积极性,提高教学效率。本文以原电池知识的信息化教学为例,探索研究了信息化教法和信息化学法在培养应用型油气储运人才中的应用,将对其他专业应用型人才的培养也具有指导意义。     

信息记录材料基材的开发研究

以原纸为支持体涂布防水涂层,作为信息记录材料的基材.主要筛选了耐水性树脂,并研究了PVB的分子量和质量浓度、防水涂层数以及涂布方式对信息记录材料表观及其性能的影响.结果表明：分子量为20万、涂布液质量浓度为5％-8％、用微凹版涂布方式涂布4层得到的基材为最佳.产品的光泽度、粗糙度等外观指标满足个性化要求,不仅适应了水性信息记录层的涂布过程,而且对信息记录材料的性能无不良影响.

Student perceptions of model-based estimating

The use of building information modeling (BIM) is well established in architecture, engineering and construction. However, previous studies note a lack of BIM expertise in academia, leading to slow adoption and limited knowledge on which to base BIM-related content. To improve course development, it is important to understand students’ perceptions of BIM-related subject matter. This study exposed estimating students (n = 214) to a model-based quantity takeoff (QTO) tutorial using Revit. Students’ perceptions of a Revit-based BIM’s usefulness for easily providing reliable and accurate material quantities were measured using a pre-test, tutorial and post-test design. Results revealed significant differences in students’ mean levels of agreement that an accurate QTO is completed for an estimator with the click of a button when a design team generated BIM model is available. Results also revealed significant differences in students’ level of agreement that a Revit-based BIM makes performing QTO by hand obsolete. This study provides educators’ insight into students’ perceptions of BIM use in QTO. Understanding student perceptions is paramount for construction management educators when designing a course and attempting to convey the value of foundational estimating skills while acknowledging the existence of more technologically advance estimating methods. Limitations and opportunities for further research are discussed.
