Using ontology-based text classification to assist Job Hazard Analysis

The dangers of the construction industry due to the risk of fatal hazards, such as falling from extreme heights, being struck by heavy equipment or materials, and the possibility of electrocution, are well known. The concept of Job Hazard Analysis is commonly used to mitigate and control these occupational hazards. This technique analyzes the major tasks in a construction activity, identifies all potential task-related hazards, and suggests safe approaches to reduce or avoid each of these hazards. In this paper, the authors explore the possibility of leveraging existing construction safety resources to assist JHA, aiming to reduce the level of human effort required. Specifically, the authors apply ontology-based text classification (TC) to match safe approaches identified in existing resources with unsafe scenarios. These safe approaches can serve as initial references and enrich the solution space when performing JHA. Various document modification strategies are applied to existing resources in order to achieve superior TC effectiveness. The end result of this research is a construction safety domain ontology and its underlying knowledge base. A user scenario is also discussed to demonstrate how the ontology supports JHA in practice.

Studies on the response of ‘Tifblue’ and ‘Woodard’ rabbiteye blueberries to fertilizers

A field study was conducted to investigate the effects of three fertilizer placement methods and 11 fertilizer formulations on plant survival, economics of replanting, yield, and fruit size of two rabbiteye blueberry (Vaccinium ashei Reade) cultivars Tifblue and Woodard. Fertilizer rates were either mixed with the soil under plants (before planting), sidedressed, or half-rate was placed under plants with the other half sidedressed. Fertilizers at planting caused a total of 34% Woodard and 12% Tifblue plants to die as compared to 6% for Woodard and none for Tifblue when no fertilizer was applied. Fertilizer formulas 2-1-1 and 5-10-10 oxide ratios placed under Woodard plants caused 100% mortality whereas Tifblue fertilized with oxide ratios 2-2-2 and 5-10-10 under plants reached the maximum 50% mortality. Splitting fertilizer placement under the side of the plants resulted in less Woodard plant mortality (30%) than placing all the fertilizer under plants (54%). However, plant mortality for the side/under group was not different than sidedressing all fertilizer (23%). A planted hectare in this experiment consisted of 1852 Tifblue and 926 Woodard plants, providing one Woodard plant to pollinate two Tifblue plants. Based on the results obtained, the 5-10-10 fertilizer placed under plants would be expected to cause half the Tifblue (926 plants) and all the Woodard (926 plants) to be replanted. Plant costs alone was estimated to be $2315 with additional replanting costs of $93 for Tifblue and much higher for Woodard. Sidedressing 5-10-10 fertilizer eight weeks after planting would have prevented plant mortality. Placement of various fertilizers under Woodard or Tifblue plants resulted in a significant increase in plant mortality as compared to side placement of fertilizers. Yield loss due to plant mortality increased linearly with the N level of the fertilizers (ranging from 0 to 2) for both cultivars. Woodard fruit size was not affected by fertilizer placement but placing fertilizers under Tifblue plants produced smaller yields with larger fruit than sidedressed plants. Blueberry plants in a virgin acidic soil may experience no reduction in yield if fertilization is completely eliminated.     

就地复合冷再生路面设计参数及工艺参数

就地复合冷再生层技术是在现场将部分旧沥青层与基层一同再生后,形成既具有一定柔性又具较大刚性的新型路面层结构的一种技术。结合渝涪高速公路沥青路面病害处治工程,研究了就地复合冷再生层的结构厚度和组合、材料参数和工艺参数以及受力分析,并取得了成功的应用经验。研究结果认为：1）在复合铣刨和再生沥青面层和水泥稳定上基层条件下,为了确保就地复合冷再生层的压实质量,其厚度应控制在26cm以内比较适宜;2）复合冷再生层的空隙率应控制小于12％;3）复合冷再生层上应设置一层防水层,而且新铺沥青混凝土厚度应不小于9cm;4）复合冷再生层混合料的主要技术性能宜采用马歇尔流值（3～5mm）、浸水劈裂强度（大于0．45MPa）、冻融劈裂强度比（大于50％）和-10℃弯曲应变（大于1800με）来控制,而动稳定度（大于2000次／mm）仅作为次要技术指标。     

和谐校园学风建设的调查与思考

大学校园的学风是学校师生整体精神面貌的全面反映,也是学生健康成才的软环境,但是当前和谐校园学风建设出现很多不和谐现象,主要原因是受到学习态度、学习环境和教学环境的影响。要通过加强特殊学生过程管理,发挥党员先锋模范作用和培养学生科技和社会实践能力等途径促进大学生综合素质的提高,推动和谐校园学风建设。
