    台灣保經代公司簽署人制度之探討

    Get PDF
    [[abstract]]自2001年金融控股法通過後,台灣之銀行、證券、農漁會、信合社等金融機構為積極發展銀行保險業務,紛紛成立保險代理人公司或保險經紀人公司,不論是以共同行銷或合作推廣的方式來進行保險招攬。然而,隨著銀行保險的業務量與市佔率的大幅提升,對於保險契約招攬品質與保護消費者之相關法令或規定更為彰顯,其中,保險經代公司所聘僱的簽署人能否適時發揮功能便是重要關鍵。本文針對現行保險經紀人、保險代理人管理規則中有關簽署人制度與現行實際執業現況提出探討,盼使主管機關能正視並儘早建立完善的簽署人制度,以利保險經紀人或保險代理人公司的良善發展。[[sponsorship]]淡江大學保險學系; 西南財經大學保險學院[[conferencetype]]兩岸[[conferencetkucampus]]台北校園[[conferencedate]]20131214~20131214[[booktype]]電子版[[iscallforpapers]]Y[[conferencelocation]]臺北市, 臺

    目的 探讨CEA、NSE、CA125、CYFRA21-1在肺癌中的检测及意义.方法 回顾性分析2015年10月—2016年12月医院收治的肺部疾病患者166例,其中89例肺癌患者设为肺癌组,其余77例肺部良性病变患者设为肺部良性病变组.另选择35名健康志愿者作为健康对照组,电化学发光法检测3组血清中CEA、NSE、CA125、CYFRA21-1含量,分析单项及联合检测对肺癌的诊断价值.结果 肺癌组患者血清CEA、NSE、CA125、CYFRA21-1分别为(4.32±0.83)ng/mL、(11.54±4.17)ng/mL、(37.89±6.69)U/mL、(4.02±0.56)ng/mL,均高于肺部良性病变组和健康对照组,差异有统计学意义(P〈0.05).肺部良性病变组和健康对照组血清CEA、NSE、CA125、CYFRA21-1比较差异无统计学意义(P〉0.05).CEA、NSE、CA125、CYFRA21-1单项诊断肺癌的敏感性偏低,特异度较高;而四项联合检测诊断肺癌的敏感性显著升高,为87.64%,差异有统计学意义(P〈0.05);特异度略有降低,差异无统计学意义(P〉0.05).结论 肺癌患者血清中CEA、NSE、CA125、CYFRA21-1升高,四项联合检测可以提高对肺癌的诊断准确性.Objective To study the test and significance of CEA, NSE, CA125, CYFRA21-1 in lung cancer. Methods 166 cases of patients with lung diseases admitted and treated in our hospital from October 2015 to December 2016 were selected and divided into the lung cancer group with 89 cases and lung benign lesion group with 77 cases in each, and 35 cases of healthy volunteers were selected as the control group, and the contents of CEA,NSE,CA125,CYFRA21- 1 in serum of the three groups were tested by the electrochemiluminescence, and the diagnosis value of single and com- bined test for lung cancer was analyzed. Results The serum CEA,NSE,CA125,CYFRA21-1 in the lung cancer group were respectively (4.32±0.83)ng/mL, (ll.54±4.17)ng/mL, (37.89±6.69)U/mL, (4.02±0.56)ng/mL; which were higher than those in the lung benign lesion group and healthy control group, and the differences were statistically significant (P〈0.05), and the differences in the CEA,NSE,CA125,CYFRA21-1 in serum between the lung benign lesion group and healthy control group were not statistically significant (P〉0.05), and the sensitivity of single diagnosis of CEA,NSE, CA125,CYFRA21-1 for lung cancer was lower and the specificity was higher, but the sensitivity of four combined test in diagnosis of lung cancer .obviously increased, (87.64%), and the difference was statistically significant(P〈0.05), the specificity slightly decreased, and the difference was not statistically significant (/9〉0.05). Conclusion The CEA, NSE, CA125, CYFRA21-1 in serum of patients with lung cancer increase, and the four combined test can improve the diag-nostic accuracy of lung cancer

    随着全球经贸活动的与日俱增,区域经济一体化的潮流也日益明显。为了应对新形势的挑战,各国也从原来侧重“多边”谈判调整为侧重“双边”谈判。双边自由贸易协定(以下简称BFTA)也越来越受到各个国家的重视,成为了不少贸易大国的重要选择。此种情况下,双边自由贸易协定也逐渐成为了各发达国家推动知识产权保护全球化的重要工具。由于发达国家和发展中国家在知识产权保护天然存在着不同诉求:发达国家希望知识产权保护全球化以维护自身利益;发展中国家则希望知识产权保护不能对其经济发展造成不利影响。因而二者对外签订的BFTA中知识产权条款有着很大不同。中国作为发展中国家的代表,当下正在经历从知识产权大国向知识产权强国的艰难...With the prosperity of global trade, the trend of the regional economic integration is more and more obvious. In order to meet the challenge, many countries change to focus on bilateral negotiations rather than multilateral negotiations. As a result, Bilateral Free Trade Agreements become an important option for most trading nations with their attention. On this condition, for many developed count...学位:法律硕士院系专业:法律硕士教育中心_法律硕士(JM)学号:1302011115024

    长的传输时延、多普勒扩散、频率选择性衰落以及有限的可用带宽等诸多因素,决定了水声通信信道的复杂性。水声信道的这些特性阻碍了水下高可靠性、高速率通信系统的发展。 单载波频域均衡(SC-FDE)技术,不仅可以有效对抗信道的频率选择性衰落,实现高速率、大容量的通信传输,而且能够避免SC-TDE复杂度大和OFDM峰均比高的不足,成为未来高速水声通信的重要组成技术。 多径信道下的高速率通信通常需要在接收端知道信道的响应。基于训练序列的方法通常被采用,其利用已知的发送序列捕获信道的时间、频率、空间信息,根据输出信号重建信道冲激响应。传统的信道估计方法,典型的有线性重建技术,被认为是适合具有丰富多径的信...In underwater acoustic(UWA),channels are characterized by long delay spread, significant Doppler effects, frequency selective fading and limited bandwidth. So, there are major challengers for the development of high-speed and reliable underwater data transmission.
