Supporting Business Intelligence Usage: An Integrated Framework with Automatic Weighting

This paper presents an integrated framework that comprises an automatic weighting method for assessing data quality (DQ) of the framework so as to better support the business intelligence (BI) usage. Specifically, we utilize business process modeling (BPM) notation and information product map and frame them into a hierarchical mapping structure. Furthermore, we develop and demonstrate an automatic weight-assignment method for evaluating critical dimensions (i.e., completeness and accuracy) of DQ of the integrated framework. Through a design science paradigm, the effectiveness of the framework and the associated DQ weighting method has been rigorously validated by faculty management users of a university. The framework together with the DQ weighting method builds user confidence by enhancing the traceability of a BI product. The automatic DQ weight assignment also provides better time efficiency because the weight of each data attribute is determined automatically based on its usage on the BI dashboard.     

超声波辅助提取天麻氨基酸的工艺研究

研究了超声波辅助提取法提取天麻中氨基酸的工艺条件。试验以氨基酸的提取率为考查指标,以提取时间、温度、乙醇体积分数和料液比4个因素进行单因素和正交实验,得到最优工艺条件为:提取时间60 min、温度45℃、乙醇体积分数60%、料液比1∶40 g/m L。在此条件下,对贵州省德江县不同品种天麻的氨基酸含量进行了测定。     

Self-Service Business Intelligence Resulting in Disruptive Technology

Self-Service Business Intelligence (BI) requires a much greater consideration of the knowledge workers or reporting and analytics users' point of view than in traditional reporting. In order to meet the reporting and analytics users' needs, much greater interaction with the BI users was required because the awareness that those doing the development frequently did not share the reporting and analytics users' perspective or even understand it. The purpose of this Self-Service Business Intelligence effort was to provide customers with a window into available business data, so they can easily manipulate their data to answer business questions. This effort explores some of the disruptive technology available to empower a significantly more information-capable customer. In providing Self-Service Business Intelligence, a significant amount of cost savings can be achieved through better communication between business and information technology (IT) individuals, reducing the required development staff in IT, and increasing agility of the enterprise by using the agreed upon Semantic definition of terms and making the business data more accessible.     

Study on Ultrasonic Extraction of Gastrodin from Gastrodia elata Bl.

Gastrodin, a pharmacologically active constituent, was ultrasonically extracted from gastrodia elata Bl. in the aqueous solution. The effects of six parameters including ethanol–water compositions, extraction time, extraction temperature, particle size, solvent volume, and ultrasonic power on the extraction yield of gastrodin were investigated. According to the orthogonal design, the optimal extraction conditions was explored as extraction temperature 60°C, extraction time 50 minutes, ultrasonic power 126 W, solvent volume 8 mL · g^?1, ethanol–water compositions 70%, and particle size 10–20 mesh. Though the yield of gastrodin via ultrasonic extraction was about 0.01% lower than that from the reflux extraction, the extraction time of the ultrasonic extraction was greatly shortened. Therefore, ultrasonic extraction has high efficiency and is proved to be very valuable in the extraction of gastrodin from gastrodia elata Bl.     

基于Web Services的企业应用集成技术

传统的企业应用集成是通过对原系统的完全改造或复杂的应用连接来实现的,这种方法不仅浪费资源,而且缺乏必要的灵活性和适应性。Web Services则可以利用松散耦合的方式将各种异构系统方便、快捷地无缝集成到现有系统中,真正实现“即插即用”。     

不同温度和气体微环境对贵州乌天麻片贮藏品质的影响

摘 要：目的 探究不同温度、气体微环境对贵州乌天麻片贮藏品质的影响。方法 以贵州乌天麻片干品为原材料,考察了在不同贮藏温度(10、25和40℃)和气体微环境(空气、脱氧剂、N2和CO2)下乌天麻片干品品质的动态变化。结果 在120 d的贮藏期内,乌天麻片的褐变指数、剪切力、总黄酮和对羟基苯甲醛含量呈上升趋势,多糖、蛋白质、总多酚、天麻素含量呈下降趋势,对羟基苯甲醇、腺苷和巴利森苷A含量变化不明显。与25℃和40℃相比,10℃贮藏条件下乌天麻片感官和有效成分含量指标更接近于0 d;与空气组和脱氧组相比,CO2充气条件下干品品质最优,其次为N2。结论 结合经济成本,10℃低温结合CO2或N2充气可作为乌天麻片推荐贮藏技术。本研究可为乌天麻片的合理贮藏、质量评价提供理论依据和技术参考。
