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.     

Forensic Application of Analytical Mechanics in Fatal Fall From a Height

Fatal fall from a height initiated with a swinging motion on the sagittal plane of the victim's body is examined. Method of analytical mechanics is adopted to establish the functional relations between the swinging angle of the body and the force needed to sustain the body until release, and the amount of the horizontal displacement that would occur after release. The analysis is applied to support an expert opinion presented in a criminal court in which two accused were convicted of murder for dropping a female victim from a bridge. The results indicate that it is unlikely for the body to locate as recorded by the police investigation report in the case. This study demonstrates that a straightforward mechanical analysis can be utilized to examine uncommon falling scenarios.     

日常性:民族地区社会工作的实践取向

解决好我国社会工作在区域之间"不平衡"的发展问题,将是社会工作专业进一步参与提升民族地区基层社会治理能力和治理体系现代化水平的重要着力点和突破口.但当前民族地区社会工作发展的相关研究,为了突出民族地区的特殊性,将文化本身从当地的日常生活中抽离出来,成为研究的客体和对象,忽略了民族地区社会工作的"日常性",即少数民族群众生活的绵延性和社会工作的结构性的矛盾与统一.从日常性出发,民族地区社会工作应当遵循浸入而非介入、主体而非客体、理解而非解释、互构而非设计的实践取向.

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.     

人民政协专门协商机构制度建设的国家治理逻辑

人民政协作为专门协商机构在国家治理体系和治理能力现代化建设中具有重要地位和作用,体现着中国特色社会主义民主政治的优势。国家治理的本质特征、价值理念与运作过程为人民政协专门协商机构制度建设赋予必要前提、基本遵循与现实要求,人民政协专门协商机构制度的功能结构主要包含政治协商、民主监督、决策参与、凝聚共识。基于体系过程与结构功能分析以及主体角色与优势效能分析,人民政协专门协商机构制度建设的关键领域分别是人民政协政治协商更好纳入国家治理决策过程以及人民政协政治协商有效发挥国家治理共识凝聚功能。     

关于混合性党内法规的理论与实证研究

混合性党内法规能不能作为概念存在?其与党政联合发文是什么关系?它因何"入"规?有没有必要"入"规?这些问题都与当前建立完善的党内法规制度体系、协调党内法规与国家法律关系、推进依规治党等任务密切相关.基于对党政联合发文的实证分析可以得出,区分混合性党内法规和其他党政联合发文,把混合性党内法规纳入党内法规体系,并进一步规范其调整范围、制定实施、备案审查、清理等基本问题,是贯彻落实习近平法治思想,加快建设完备的党内法规制度体系,实现以"良法促进发展,保障善治"的基本条件.为此,还应当结合党内法规的形式和实质特征,合理控制党政联合制定混合性党内法规的数量,并明确混合性党内法规的边界,将其限定在党政机构统筹改革、党的直接管理、党政同责等领域.     

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.     

刑事被害人当事人化的反思与制度重构

刑事被害人当事人化的实质是犯罪损害追诉方式的公私合一,该制度设计混淆了公益和私益两种不同性质的诉讼,导致两种权益保护相互冲突进而对刑事司法结果公正造成负面影响。公私分离是刑事被害人去当事人化的当然制度选择,其立法对策主要包括在刑事立法中确立被害人为特殊诉讼参与人、废除被害人在刑事审判中就定罪量刑发表意见的权利、废止被害人刑事自诉权和切断其引起刑事二审、再审的程序路径。同时需要完善相关配套举措,如允许被害人对其物质和精神损害单独提起民事诉讼、完善精神损害赔偿制度、建立刑事被害人国家补偿制度等。     

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。
