桂林傩舞现状及问题研究--以秀峰区张家村为例

受神秘的巫文化影响，桂林傩舞有着悠久的历史，曾经盛极一时，但近年来逐渐趋于衰退。通过实地考察张家村傩舞，可以发现桂林傩舞艺术面临着缺乏继承人、观赏性不足、舞蹈造型和手势表达失传、道具不精、基层教育不重视、表演人员经济困难等生存困境。当地政府应该加强宣传力度，加大资金投入，培养傩舞表演的继承人和道具制作的传承人，强化对傩舞的理论与实践研究，不断提炼傩舞的特色内涵，促进桂林傩舞的保护和传承。

Accurate forecasting of the undecided population in a public opinion poll

The problem of pollsters is addressed which is to forecast accurately the final answers of the undecided respondents to the primary question in a public opinion poll. The task is viewed as a pattern‐recognition problem of correlating the answers of the respondents to the peripheral questions in the survey with their primary answers. The underlying pattern is determined with a supervised artificial neural network that is trained using the peripheral answers of the decided respondents whose primary answers are also known. With peripheral answers as inputs, the trained network outputs the most probable primary response of an undecided respondent. For a poll conducted to determine the approval rating of the (former) Philippine president, J. E. Estrada in December 1999 and March 2000, the trained network predicted with a 95% success rate the direct responses of a test population that consists of 24.57% of the decided population who were excluded in the network training set. For the undecided population (22.67% of December respondents; 23.67% of March respondents), the network predicted a final response distribution that is consistent with the approval/disapproval ratio of the decided population.

食管癌患者硒营养状况的评价

以机体硒水平，ＧＳＨ－Ｐｘ，ＳＯＤ的活性，相关的抗癌致癌元素的综合效应比值，食管癌死亡率与硒等元素的多元回归分析及ＭＤＡ的含量等合指标，评价食管癌患者的硒营养状况，结果表明，食管癌患者的营养状况差，表现为：硒水平低、含硒酶ＧＳＧ－Ｐｘ以及抗氧自由基的ＳＯＤ活性差，脂质过氧化加剧；ＭＤＡ含量高将使核酸，蛋白质含等含氨基活性物质产生交联反应而使细胞失活，食管癌患者硒营养状况差，与癌肿的一定相关关系，是
