A novel method for cyanide quantification in human whole blood using ion chromatography with amperometric detection and its application to cyanide intoxication cases

Cyanide is a highly toxic agent that has been frequently used for suicide in South Korea. It is also used in various industrial fields, such as metal plating, in which many accidental cyanide intoxications have occurred. To overcome the disadvantages of conventional cyanide analysis methods, a simple and fast method for the analysis of cyanide in whole blood using ion chromatography (IC) with amperometric detection was developed in this study. Whole blood samples were deproteinized, diluted, and analyzed using an IC–amperometric detection system. The limits of detection and quantitation were 0.1 and 0.2 mg/L, respectively. The method showed good linearity in the range of 0.2 to 50 mg/L with R² > 0.99. The intra- and inter-assay precision and accuracy values were <10%. The established method was successfully applied to analyze whole blood samples from three cyanide intoxication cases.

The effects of national cultures on two technologically advanced countries: The case of e-leadership in South Korea and the United States

The increased use of information and communication technologies (ICTs) has triggered enormous innovation in the public sector and created positive public value at the managerial, delivery of services, and policy levels. However, these positive outcomes do not automatically accrue simply by adoption of ICTs as public leaders can fail to adopt relevant new ICTs, use them poorly, or use them in ways that actually diminish public value, which raises the question of the importance of e-leadership. This article examines e-leadership and innovation capacity at the individual public manager level and fills in some gaps about the practice and implementation of ICTs in the public sector. We explore eight research questions useful in theorizing about e-leadership, develop constructs of e-leadership, and describe the current development of e-leadership. By comparing e-leadership in two country settings (South Korea and the United States), we also overcome the limitations of the existing Western-oriented studies about innovations in the public sector. In addition to the growth of e-leadership use and requirements for a variety of competencies equivalent to, but separate from, traditional communication competences, we find that national cultures exert significant influence on the major constructs of e-leadership, which implies that an effective e-leadership strategy should consider cultural contexts seriously.     

Molecular Identification of Necrophagous Dermestes Species in South Korea Using Cytochrome c Oxidase Subunit I Nucleotide Sequences (Genus Dermestes)

Species identification of necrophagous insects found on a dead body is an essential key in applying medicolegal entomology to the estimation of postmortem interval (PMI). Due to limited morphological identification of insect evidence, several studies have identified species using molecular information such as DNA markers. While considerable cytochrome c oxidase subunit I (COI) gene sequence data of necrophagous fly species have been collected and annotated, those of necrophagous beetle species have not. Since necrophagous beetles such as Dermestes species have a larval period longer than that of flies, beetles are useful in even the late decomposition phase in estimating minimum PMI. To obtain the full-length COI gene sequences of six Dermestes species collected from South Korea, we designed primers for polymerase chain reaction amplification and sequencing. The obtained full COI nucleotide sequences were used for performing phylogenic analysis and comparison with previously reported sequences. The results demonstrated that the COI gene sequences could be used to identify forensically important Dermestes species in South Korea.     

论国际资源争夺中的金融战

随着金融资本的扩张、金融全球化的发展,以美国为主导的西方国家金融寡头势力空前膨胀,并以新的形式出现,成为国际垄断资本,操控资源市场,加紧对国际资源的争夺。国际资源争夺的历史轨迹与内在逻辑清晰表明:在经济全球化的大潮下,一国金融实力的大小直接决定其国际资源利用水平的高低,国际资源争夺的实质是金融战。这对于西方资源消费国尤其是美国具有深远的战略意义,对于面临“资源困局”与“金融窘境”的东亚更有着重要启示。

专利实用性要件的国际协调研究

专利实用性要件是当前《实质性专利法条约》签订中的争论焦点之一。在此问题上,欧洲、美国等分别坚持自己的Industrial Applicability(工业应用性)标准与Utility(实用性)标准,二者存在竞合,更有实质的差异与分歧,各自的演变及二者的协调反映了专利制度作为商业竞争手段的工具性的一面,也体现了实用性要件作为专利权人、产业集团与社会公众利益平衡的调节因素的一面。最后的协调结果可能会是欧、美工业应用性/实用性标准的某种妥协与折中。我国对该问题应加紧研究、积极参与,在专利制度国际化协调进程中寻求对我国最为有利的结果。     

国际法框架下的人民币汇率制度选择

近年来,人民币汇率及汇率制度选择问题成为国际经济中的持续热点问题之一。随着入世过渡期的结束,中国经济已经日益融入世界经济体系,人民币汇率及汇率制度问题已经成为中国经济发展中必须长期面对的常态性问题。对于这个问题的研究,不应仅限于以往研究中的币值低估与否,是否违反相关国际公约等方面的单一研究模式,而需要在相关国际法框架下,从经济、政治及国际法等多角度加以综合研究,以制定相应的长期应对策略,并在此基础上通过对国内法上相关制度的完善保证中国经济的长期平稳发展。
