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.

论互联网时代诽谤罪的公诉范围

我国刑法对诽谤罪采取自诉为主、公诉为补充的双轨制模式。由于刑法但书“严重危害社会秩序和国家利益”的公诉依据具有模糊性,同时司法解释本身缺乏解释力和可操作性,存在同义解释、近义解释等问题,加剧了公诉诽谤罪和其他罪名之间的冲突和竞合,特别是当被害人为地方领导干部时,诽谤罪的公诉权在实务中存在被滥用风险,部分限制公诉权的要件在实务中被淡化甚至忽略。从相对狭义的角度看,“严重危害社会秩序和国家利益”只有在行为人对侵犯个体法益具备主观故意,但对侵犯社会法益或国家法益不具备主观故意(或无法证明其具备故意)的情形下,才有其独特的法律适用价值并不与刑法其他罪名相冲突。为妥善处理和平衡诽谤犯罪中惩治犯罪和保障人权的关系,适应互联网时代的内外部变化,建议通过修改我国刑法,将诽谤罪区分为情节不严重、情节严重、情节特别严重的三种形态,为充分保障宪法权利,情节不严重的不作为犯罪处罚;为充分保障自诉权,情节严重的为绝对告诉乃论;为依法惩治犯罪,对符合特定形式要件和实质要件,情节特别严重的诽谤犯罪可以依法公诉,以维护网络信息秩序。

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.     

The Real Motive

U.S.President Donald Trump's Middle East peace plan,called by some the"deal of the century,"is an important step-to win the support of Jewish voters in this year's presidential election.Given the complexities of the situation in the Middle East and the failure of negotiations between Israel and Palestine,the plan is unlikely to take the peace process between the two key actors forward.     

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.     

论国际投资中的国家责任问题

国际投资中的国家责任问题主要涉及国际投资的法律保护问题 ,如对外国投资和投资者的待遇标准、国有化或征收及其补偿问题。另外 ,还涉及特许权协议、拒绝司法、外交保护等问题。就外资待遇而言 ,发展中国家应根据其经济发展的实际情况在双边投资保护条约中慎重承诺。笔者通过对国有化问题的分析 ,认为国家在这个问题上所承担的国家责任不是传统国际法上的国家责任 ,而是一种“合法行为引起的国家责任”。关于特许协议 ,笔者认为它是国内契约。此外 ,在国际投资中 ,还涉及因污染转嫁而产生的国家责任。     

法、道德和软实力

软实力就是文化实力,代表了一个国家的综合实力,决定着一个国家的未来。软实力由观念文化所组成,内容丰富,但是其核心是法和道德的观念和知识。一个国家的软实力表现在法和道德的状况上。法和道德的基本精神是创造和谐,因此,具有普世的价值。
