Design and Implementation of Centralized Business Support System for Telecom Operators

目前,国内各通信运营商的业务支撑系统都是各省分公司自行建设，每年小省的建设维护费用大概在两千万（小省指业务规模小省如甘肃、青海、西藏等），大省大概在2个亿左右（大省指业务规模大省如北京、上海、广东等）。通信运营商一年的业务支撑系统建设维护费用大概在30个亿左右。目前各运营商竞争激烈，如果建立集中的业务支撑系统，一年的信息化系统建设维护费可控制在很小的范围内。另外业务支撑系统集中后可实现全国业务规则、产品统一规划，使运营商在业务管理、产品支撑方面的优势更加明显。 集中系统需要支持全国各省的各种复杂业务、需要承载全国数亿的用户数据、需要具备很强的容灾能力、需要并具备很强的枢纽交互功能。为解决业务...At present, business support systems of domestic telecommunication operators are the provincial branch to construction, the construction of small annual maintenance costs about twenty million (small province refers to the small scale of business such as Gansu, Qinghai Province, Tibet province), about 2 hundred million or so (big province refers to the scale of business the province such as Beijing...学位：工程硕士院系专业：软件学院软件工程系_工程硕士(软件工程)学号：X201223020

Design and Implementation of Phone Contacts Based on Android

Android是Google公司发布的一款基于Linux内核的手机操作系统。现如今，Android在各国的市场占有率不断攀升，国内厂商和运营商也纷纷加入到Android阵营中。这都预示着Android时代的到来。另一方面，随着人们之间的联系越来越紧密，手机已成为人们生活中必不可少的一部分。作为手机最基本的功能——通信，通讯录扮演着重要的角色。然而，成百上千的联系人杂乱无章地显示，几千条的短信息与通话记录毫无归类，用户在使用过程中感受到操作极其不便，步骤繁琐，信息难管理等问题，Android自带的通讯录并没有很好的解决这系列问题，因此迫切地需要一款辅助软件来管理我们的通讯。 基于上述分析，本文...Android is one mobile phone operating system based on the Linux operating system kernel, announced by Google in 2007. Today, Android markets share in the countries all over the world. Without wandering, the age of Android is approaching. At the same time, with the increasing contact need between people, mobile phone is one indispensable for people lives. As the basic function of mobile phone - com...学位：工程硕士院系专业：软件学院_工程硕士(软件工程)学号：X201023022

英语专业实行阶段性口语测试初探

由于英语专业四、八级口试的受众面还比较窄,不少英语专业学生的口语能力还无法得到科学、客观、有效的评测。在英语专四、专八口试成为一种普遍的、常态的大规模口语测试之前,组织校级或者院级的英语专业阶段性口语测试不失为一种有益的补充。它不仅可以实现口语教学的教考分离,还可以利用测试的反拨效应来促进口语教学质量的不断提高。探讨了英语专业实施阶段性口语测试过程中在试题编写、测试方式、考试实施、评分方法以及成绩汇报方面的具体操作方法。集美大学横向课题(S510084); 福建省教育厅科研基金项目(JA101182S

Core-shell Hydroxyapatite Combined with Bone Morphogenetic Protein 2 in Periodontal Regeneration Treatment in Dogs

目的初步评估贝壳多孔羟基磷灰石基骨修复材料及该材料和骨形成蛋白-2联合应用引导比格犬牙周组织再生的效果。方法选取18月龄比格犬6只,牙周基础治疗后1周,在下颌第二、三、四前磨牙,建立急性牙周骨缺损模型,依照分组情况进行不同治疗。实验组(T组)植入骨修复材料和骨形成蛋白-2;阴性对照组(nC组)植入骨修复材料;空白对照组(bC组)不植入任何材料。实验设计采取同颌同名牙对照,同一只比格犬的3对同颌同名牙分别为:空白对照组和阴性对照组,阴性对照组和实验组,空白对照组和实验组。术后12周,处死动物,MICrO-CT检查并对数据进行统计学分析。结果材料植入后,未见材料溢出,植入局部和全身都未见明显不良反应。3组缺损都有一定程度骨再生,以T组再生组织量最多,bC组最少。MICrO-CT结果显示:T组、nC组和bC组的骨再生平均高度为(4.50±0.47)MM(、1.75±0.42)MM和(0.87±0.31)MM。nC组和bC组相比,差异有统计学意义(P<0.05)。T组与nC组和bC组相比,差异均有统计学意义(P<0.05),且有临床意义。结论贝壳多孔羟基磷灰石基骨修复材料和骨形成蛋白-2联合应用于比格犬,可以获得更好的引导组织再生效果。Objective To evaluate the ability of core-shell hydroxyapatite bone graft material alone and combined with bone morphogenetic protein 2(BMP-2) in periodontal regeneration treatment in dogs.Methods Thirty-six defects were created in six 18-months male beagle dogs at the sites of the second,third and fourth mandibular premolars one week later after the dogs were treated with non-surgical periodontal therapy.Different treatments were carried out according to which group the teeth belonged.There are 3 groups.The test group(group T) was treated with core-shell hydroxyapatite bone graft material combined with BMP-2;the negative control group(group NC) was treated with core-shell hydroxyapatite bone graft material alone and the blank control group(group BC) was treated with no graft material.When a tooth was selected into one of the 3 groups randomly,the tooth with the same name on the other side in the same jaw was selected into another group.6 defects in the same dog were made and divided into 3 groups.The animals were sacrificed 12 weeks after surgery and analyzed by Micro-CT.Results There was no adverse reaction after material was planted.There were bone regenerations in all groups.Group T got the best bone regeneration while group BC got the least bone regeneration.The biggest height of bone regeneration for group T,group NC and group BC were(4.50±0.47) mm、(1.75±(0.42) mm) and(0.87±0.31) mm according to Micro-CT evaluation.There were statistical difference of bone regeneration height between group NC and group BC.There were statistical differences between group T and group NC and between group T and group BC.Conclusion More periodontal tissue regeneration could be got when core-shell hydroxyapatite bone graft material was used with bone morphology protein 2.南京市医学科学技术发展专项项目(ZKX07022);天津市生物医学材料重点实验室开放课题;南京市医学科技发展青年人才启动项目(QYK10166
