韩国由威权向民主转变的影响因素 总被引:1,自引:0,他引:1
韩国20世纪80年代的两次民主运动产生了完全不同的效果.1980年的光州事件遭到镇压,而1987年的六月民主化抗争则成功地实现了总统直选制改宪.主要的影响因素在于:经济社会的发展为韩国在1987年走上民主轨道奠定了坚实的基础.1980年的惨案也迫使威权政府1987年在选择动用武力方面更加谨慎.统治者内部的分化也有助于在1987年通过妥协和平地向民主过渡.在外部因素方面,美国立场的变化至关重要. 相似文献

We have analyzed variation of the mitochondrial DNA (mtDNA) hypervariable segments I and II (HVS-I and HVS-II) in 185 randomly chosen individuals from Korea to provide an expanded and reliable Korean database. Combined sequence comparison of HVS-I and HVS-II led to the identification of 167 different haplotypes characterized by 154 variable sites. One hundred and fifty-one of the haplotypes were individual-specific, 14 were found in two individuals and 2 were found in three individuals. A pairwise comparison of the 185 HVS-I/II sequences found an average of 10.11 +/- 4.63 differences between individuals. The random match probability and gene diversity for the combined hypervariable regions were estimated at 0.66% and 0.9988, respectively. Analyzing the expanded database including three previously reported data sets and the present data using haplogroup-based comparisons and comparison with closely related sequences allowed errors to be detected and eliminated, thus considerably improving data quality. Sample division comparisons based on PhiST genetic distance measures revealed no significant population differentiation in the distribution of mtDNA sequence variations between the present data set and a database in The Scientific Working Group on DNA Analysis Methods (SWGDAM), but did indicate differences from other sets of data. Based on the results of mtDNA profiles, almost all of the mtDNA types studied here could be classified into subsets of haplogroups common in east Asia, and show that the Koreans possess lineages from both the southern and the northern haplogroup complexes of east Asian populations. The new data, combined with other mtDNA sequences, demonstrate how useful comparison with closely related mtDNA sequences can be for improving database quality, as well as providing haplotype information for forensic and population genetic analyses in the Korean population. 相似文献

中国共产主义运动的先驱李大钊1920年8月17日在<晨报>发表<要自由集合的国民大会>论及"民意"时指出:"一世怪杰的袁世凯,以符合民意而再起者,卒以伪造民意而亡."应当说,这句话集中反映了接受马克思主义唯物史观的李大钊,对袁世凯一生的大体看法和最终评价.很显然,李大钊并未因袁世凯最后"卒以伪造民意而亡",而全盘否定其曾"以符合民意而再起"等历史功绩,依然认为当时已经死去4年的袁世凯是"杰",只是为"一世怪杰". 相似文献

This article explores the attitudes of officials in the upper echelons in Chinese provincial and local government toward the origins of administrative reform. The authors examine the somewhat dichotomous argument that reform imitates the West or is indigenous and contend that both influences are present. Data drawn from a survey of party cadres and government officials show that cultural factors (time in government, overall knowledge of administrative reforms, together with familiarity with the move from a planned system of government to a market economy) and structural variables (upper echelon and familiarity with business management techniques) are correlated with learning from the West. Cadres and officials who spend more time managing outward and those who are familiar with performance assessment do not learn from the West. The theoretical and research implications of these findings—that learning from the West is an important influence on the adoption of administrative reforms in China—are discussed. 相似文献

解决中药知识产权保护问题离不开国际化因素的考量,但是国际化并不能等同于西方化,尤其是美国化的西药审批及保护标准,这是中医入欧盟零注册危机给国人的最新启示.从专利特别保护、传统知识特别保护及公用知识无保护三种主要路径对中美中药市场竞争的影响出发,应用实效方法论的重要工具博弈均衡理论,对中美中药及植物药保护的不同选择路径不同利益效果作了对比性的数据及逻辑分析.研究发现,我国对中药知识产权国际化保护的最佳选择应是理清中药作为传统知识的知识产权地位,而促进美国对植物药的专利化具备利益的可行性.建议在构建国内中药传统知识保护的专门法律制度的同时,创建性地促进中药的科技创新、国际合作以及相关国际公约的修改. 相似文献

A sensitive analytical method was developed for the quantitative determination of tetrodotoxin (TTX), a powerful sodium channel blocker, in human postmortem whole blood. The sample mixture was cleaned up using cation exchange SPE catridge after protein precipitation by methanol and then separated on a PC-HILIC (phosphorylcholine hydrophilic interaction liquid chromatography) column (150 mm × 2.0mm i.d., 5 μm) using a isocratic elution of 1% acetic acid and acetonitrile. The identification of TTX was performed on tandem mass spectrometry with electrospray ionization interface in positive ion mode. The retention time of voglibose (internal standard) and TTX was 5.1 and 6.0 min, respectively. TTX and internal standard (voglibose) were monitored and quantitated using the ion transitions: the respective precursor to product ion combinations, m/z 320/302 for TTX and m/z 268/92 for voglibose in the multiple reaction monitoring (MRM) mode. The recovery of TTX and voglibose was 61.4% and 62.8%, respectively and the good accuracy (97.7-103.9%), linearity (2-1200 ng/mL) and reproducibility were shown in this method. The limit of detection and limit of quantification were 0.32 ng/mL and 1.08 ng/mL, respectively. This method was applied in the case of three fishermen who were poisoned (including one death) by unknown fish on their boat in October 2010. In this case, the levels of TTX were 27.2, 30.0 and 29.7 ng/mL in heart blood, peripheral blood and serum of a victim, were 3.1 and 12.1 ng/mL in peripheral blood and 3.9 and 12.8 ng/mL in serum of two survivors, respectively. 相似文献
