R&D组织的冲突分析与管理对策

R&D组织作为一个开放型的社会系统 ,其整体性能受系统的要素和环境的影响。在中国的国情下 ,人力资本和生产企业是R&D组织最重要的内部要素和外部环境。在系统的自组织过程中 ,基于以上两者会产生特有的内部冲突和外部冲突。因此 ,通过改善R&D组织的要素和环境的性能 ,来寻找解决冲突的管理对策 ,最终达到优化系统整体性能的目的     

电视胸腔镜下微创脊柱侧弯前路松解术的初期临床结果

探讨电视胸腔镜在严重脊柱侧弯前路松解中的应用价值,并对其初期临床结果进行分析.2001年11月-2002年8月,共11例严重脊柱侧弯患者接受电视胸腔镜下前路松解,均为女性,特发性胸椎脊柱侧弯,年龄14～17岁.冠状面Cobb角90°～100°,Risser征+++～++++,松解范围T5～T12,松解节段5～7.术后行牵引二周再行后路TSRH矫形内固定术.术中出血量为100～150mL,手术时间180～220min,术后引流量520～650mL,引流时间48～96h,二期后路手术矫正率平均为58%.电视胸腔镜下脊柱侧弯的前路松解在不影响矫形手术效果的同时,能减少组织损伤,降低感染可能,减轻术后疼痛,缩短病人的康复时间.     

CO2泡沫压裂液两相流流动特性的试验研究

通过大型高参数泡沫压裂液试验回路首次详细研究了实际压裂条件下CO2泡沫压裂液的流变特性,得出了实际压裂条件下CO2泡沫压裂液流变参数的计算关联式,从而为低渗油气藏泡沫压裂技术的有效实施提供了试验依据.研究表明:在实际施工条件下,CO2泡沫压裂液具有剪切稀化性质,可用幂律模型来描述;其有效粘度随剪切速率、温度的增高而减小,随压力、泡沫质量的增大而增大;相对而言,温度和泡沫质量对流变参数的影响比压力的影响明显,在该试验范围内,温度和泡沫质量对流变参数的影响呈指数规律变化.

Genetic Diversity in Populations of Sepiella maindroni Using 16S rRNA Gene Sequence Analysis

Part of the 16S rRNA gene is amplified with PCR and sequenced for 5 populations of common Chinese cuttlefish Sepiella maindroni:three from the South China Sea,one from East China Sea and one from Japan.The result shows that a total of 5 nucleotide positions are found to have gaps or insertions of base pairs among these individuals,and 13 positions are examined to be variable in all the sequences,which range from 494 to 509 base pairs.All of the individuals are grouped into 7 haplotypes (h1-h7).No marked genetic difference is osberved among those populations.All of the individuals from Nagasaki belong to h1 and the h3 haplotype is found only in the coastal waters of China.A→←G transition in Nucleotide 255 is suggested to be taken as a kind of genetic marker to identify the populations distributed in East-South China Sea and the Nagasaki waters of Japan.     

Improved Dissolve Detection for Video Segmentation

It is difficult to detect dissolve accurately in video segmentation. Two new parameters AEI and/DM are computed to describe dissolve. An improved method based on the change curves of AEI and/DM is proposed to detect dissolve accurately. The experiments show that this method can detect dissolve accurately.     

Classification of Medical Brain Images

Since brain tumors endanger people‘s living quality and even their lives, the accuracy of classification becomes more important. Conventional classifying techniques are used to deal with thosedatasets with characters and numbers. It is difficult, however, to apply them to datasets that include brain images and medical history (alphanumeric data), especially to guarantee the accuracy.For these datasets, this paper combines the knowledge of medical field and improves the traditional decision tree. The new classification algorithm with the direction of the medical knowledge not only adds the interaction with the doctors, but also enhances the quality of classification. The algorithm has been used on real brain CT images and a precious rule has been gained from the experiments. This oaoer shows that the ahzorithm works well for real CT data.
