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.     

Less Safe in the Ivory Tower: Campus Sexual Assault Policy in the Trump Administration

ABSTRACT

Since the late 20th century, the federal government has regulated colleges’ and universities’ handling of campus sexual and gender-based violence (CSGBV). Although the arc of history has bent toward establishing greater protections for victims of such violence, new proposed regulation by the U.S. Department of Education under the Trump administration focuses more heavily on ensuring due process rights for students accused of CSGBV. Most recently, in November 2018, U.S. Secretary of Education, Betsy DeVos submitted a proposed rule change to the regulation of Title IX of the Education Amendments of 1972. This article provides the historical context for this most recent proposed federal regulation of CSGBV and discusses the criticism of this proposal that, if it is implemented, students would become less safe in the ivory tower.

South Korea's Faustian Attitude: The Republic of Korea's Decision to Send Troops to Iraq Revisited

South Korea sent troops to Iraq not because of any perceived threat from an Iraqi nuclear programme, but to seek influence over American foreign policy towards North Korea. At no point did the general public support the American invasion and war in Iraq; most South Koreans also opposed sending troops to Iraq. However, the government chose to send first non-combat and later combat troops to Iraq, and the public approved of the former choice and support was growing for the latter. The liberal President Roh Moo-Hyun had to persuade the public on this issue, even in opposition to his core supporters, risking political isolation. What the public and the President aimed at was a peaceful resolution of the North Korean nuclear issue and business opportunities. The national interest that South Korea pursued in sending troops to Iraq was policy influence over the US guarantee not to use military power against North Korea.
