THE EXPERIMENTAL STUDY ON EFFECTS of TEA POLYPHENOLS AGAINST HYPERURICEMIA IN RATS

目的观察茶多酚(TP)对高尿酸血症大鼠体内尿酸水平的影响,探讨其降低血尿酸作用的可能机制。方法取雄性Sd大鼠30只,分为空白对照、高尿酸血症模型、TP低、中、高剂量5组,每组6只。对模型组及TP干预组大鼠灌胃给以15 g/kg·d酵母膏、200 Mg/kg·d腺嘌呤及30 Mg/kg·d氧嗪酸钾联合造模30d;TP干预组在造模10d后灌胃给予TP,连续20d,剂量分别为100、200、300 Mg/kg·d,模型组继续灌胃造模剂,空白组灌胃等量生理盐水。实验结束时,测定血液和尿液中的尿酸(uA)、肌酐(Cr)及尿素氮(un)含量,检测肝脏和血清中的黄嘌呤氧化酶(XOd)活性以及尿酸排泄分数(fEuA)。结果模型组血尿酸水平较空白对照组明显升高(P0.05);模型组肝脏XOd活性明显高于空白对照组(P0.05).The activity of XOD in liver in model group was significantly higher than those of the controls(P<0.01), and lower in low dose group than those of the model group(P<0.05).The FEUA level of rats in medium group was higher than those of the controls and models(P<0.005).Conclusion Tea polyphenols reduce blood uric acid level in rats with hyperuricemia and the related mechanism may be associated with its inhibition on the activity of XOD in liver

Analysis of Consumer Lifestyles and Transaction Records – Take the Database of Credit Cards as an Example

現在的行銷模式必須考慮到消費者的「動態性」和「異質性」，資料庫分析和問卷調查的結合使行銷研究人員更加洞悉消費者的購買行為，並從中找出商機。本研究以東方線上E-ICP (Eastern Integrate Consumer Profile) 於2002年公布的「台灣成年消費者」市調的6種生活型態：台灣牛、逍遙馬、黑熊、貓頭鷹、花蝴蝶、雲豹，和7類消費品項交易紀錄的頻率比及金額比進行邏輯斯迴歸分析，找尋其中的相關性，並建立能用交易紀錄預測生活型態的模型。此模型能幫助企業依據每一個顧客過去的購買行為模式，推測出其生活型態，並有效的篩選出適合目標客群的各項行銷活動，使活動的總效益能達到最大，資源浪費降到最低，而能使顧客對公司的貢獻達到最大化。Nowadays, when it comes to marketing, the dynamic and heterogeneity of consumers need to be considered. Database analysis and market research have helped market analysts understand much more about consumer behavior, so enterprises can grasp the opportunities to drive their businesses. This thesis cross-analyzes 6 consumer lifestyles released by E-ICP in 2002 and 7 categories of transaction records by collecting data from credit card questionnaires and a bank’s database. It aims to determine the connection between consumer lifestyles and consumer buying behaviors with a logistic regression model to predict customers’ lifestyles based on their transaction records. Thus, the model can assist enterprises in segmenting its customers with lifestyles and designing marketing activities for different target customer groups, which can increase the efficiency and effectiveness of the marketing resources

A Follow-up Intervention Study on Visual Health of Primary SchoolStudents Affected by Outdoor Physical Activities

目的:探究增加户外体育活动时长对小学生视力健康水平的影响。方法:采用实验法和问卷调查法,在北京市某校2～6年级各1个班选取实验对象,每个班随机抽取50%的学生作为干预组,另外50%的学生作为对照组,一共有257名小学生参与干预实验与调查,干预时长为9个月,其间每隔3个月对受试小学生进行一次视力检查和问卷调查,对干预组实施为期9个月的户外体育活动干预,一学年后对受试小学生视力健康状况及干预效果进行分析。结果:受试小学生裸眼远视力呈现下降趋势;在保证常规体育活动的基础上,每周增加6 h及以上时间的户外体育活动,可显著改善小学生视力;在坚持6个月及以上时间的户外体育活动的前提下,每周增加1 h的户外体育活动,受试小学生裸眼远视力可提高0.005。结论:受试小学生裸眼远视力随时间的推移呈现逐渐下降趋势;增加户外体育活动时长对受试小学生视力具有保护作用,户外体育活动时长与受试小学生视力健康水平之间存在因果关系。这为通过增加户外体育活动时长预防小学生视力不良提供了理论和实践依据。</p

一种基于深度学习的机械臂分拣方法

针对分拣过程中视觉系统识别复杂物体时速度慢、对环境变化适应性不足的问题，提出一种基于轻量型卷积神经网络的机械臂快速分拣方法。该方法首先使用基于轻量型卷积神经网络的MobileNet-SSD算法对图像中的目标物体进行检测，获取目标类别和位置信息；然后根据检测输出结果对图像进行预处理和边缘检测，最终得到校正后的定位结果。在PROBOT Anno机械臂平台上进行分拣实验，实验结果表明，相比于传统的图像处理方法，提出的方法能对复杂目标物体实现快速的检测和定位，对于目标形态和环境的多样性来说具有更好的鲁棒性
