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.     

在惩罚犯罪与保障人权之间：关于监听的法律思考

监听是世界各国为应付犯罪形势的新变化而发展起来的一种高技术化、高隐密性的强制侦查措施，其出现对于侦查机关打击和惩罚犯罪发挥了极其重要的作用。但是另一方面，监听的采用又严重侵犯了公民隐私权，因此，各国都对监听的采用规定了严格的法律程序，以防止侦查机关滥用监听，过度分割公民权利。我国刑事诉讼立法上对监听缺乏明确规定，这不利于保障公民人权，应当加以改进。     

公正执法:构建和谐社会的重大公安议题

公安机关必须深刻认识公正执法的极端重要性,树立新型的公安执法观念公正执法是社会和谐的大前提,是长治久安的重要保证,是公安工作的生命线;公安执法存在的主要问题与形势需要还不相适应,内部违法违纪、执法犯法屡有发生,对公安执法非议依然不少;以公正执法来推进和谐社会建设,必须改革公安管理体制和工作机制,当前要正确理解、贯彻双重领导体制下的公安执法范畴,通过修改、完善刑事诉讼法严防冤案错案,坚决走政治建警、从严治警之路,落实执法监督措施.     

论自主创新与政府促进机制的完善

《国家中长期科学和技术发展规划纲要(2006-2020年)》按照党的十六大总体部署,立足我国国情、以增强自主创新能力为主线,以建设创新型国家为奋斗目标,对我国未来15年科学和技术发展作出了全面规划与安排。在我国自主创新能力提高的进程中政府是关键,一些发达国家政府支持企业自主创新的经验值得重视和借鉴。     

上层建筑是为产生它的经济基础服务的

按照马克思主义创始人的观点,无论是政治的上层建筑,还是思想的上层建筑,都是适应一定的经济基础的需要而产生,并且是竖立在这种基础之上的。有什么样的经济基础,就要求有什么样的上层建筑;随着经济基础的变更,上层建筑也要相适应地变革。同时,上层建筑也反作用于经济基础。

Spatial variation of refractive index in a pane of float glass.

In the statistical interpretation of forensic glass evidence it is standard practice to make the assumption of homogeneity of the refractive index (RI) of the source glass, or of localized homogeneity. However, the work of Locke and Hayes showed that, for toughened windscreen glass, this assumption might not be true. This work is well cited, but there appears to have been little follow-on published research. Furthermore, the toughening process is something known to affect the refractive index, and is a process that float glass does not undergo. Float glass is a major component of casework in New Zealand and for that reason it would be interesting to know whether the findings of Locke and Hayes apply when dealing with float glass. In this paper we describe an experiment similar to that of Locke and Hayes, systematically examining the variation of RI in a pane of float window glass. It was found that, although there were no systematic differences in refractive index, there were observable differences across the pane.
