Despite the high mortality rate associated with coronavirus disease 2019 (COVID-19), no clinical autopsy has been reported among the deceased during the pandemic by the Korean quarantine authorities. Notably, since 2020, forensic autopsies are performed in suspected and confirmed cases of COVID-19 infection. The first case of death secondary to COVID-19 pneumonia in Korea was reported in November 2021. We recently performed a forensic autopsy of a couple (85-year-old man and 81-year-old woman) who were discovered dead at home. Gross examination showed lobar consolidation of lungs, and microscopic evaluation revealed diffuse alveolar injury in the acute phase and thrombi in small arterioles; these findings were consistent with those reported by previous studies that have described COVID-19 pneumonia. Based on the aforementioned findings, we concluded that the couple died of COVID-19, and our study is the second Korean study to report these findings.
Offshore wind turbines are divided into an upper wind turbine and a lower support structure. Offshore wind turbine system is required to secure high reliability for a variety of external environmental conditions compared to ground wind turbines because of additional periodic loads due to ocean wave and current effects. In this study, extreme load analyses have been conducted for the designed offshore wind turbine foundation with weight control functionality using computational fluid dynamics (CFD) then structural analyses have been also conducted to investigate the structural design requirement.
A medicolegal autopsy is usually performed to determine the cause and manner of death based on judicial or administrative directives applicable in cases of unusual deaths. Social interest in medicolegal autopsies is increasing in recent times. In this study, we investigated medicolegal autopsy rates in Korea and compared these with rates reported by other countries. We obtained data regarding autopsies performed between 2016 and 2020 from the relevant institutions. We calculated the autopsy rate using mortality data from Statistics Korea. The number of medicolegal autopsies performed increased from 8,382 in 2016 to 9,308 in 2020, with an annual increase in numbers. The medicolegal autopsy rate of total deaths increased from 2.98% in 2016 to 3.05% in 2020, and the medicolegal autopsy rates of unusual deaths increased from 12.45% to 13.12% during the same period. However, it repeated an increase and a decrease by year during the study period. In conclusion, the numbers of medicolegal autopsies performed in Korea have been increasing since 2016; however, the medicolegal autopsy rate has been maintained.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
