Background: This study was conducted to analyze the current problems in completing death certificates and to identify the correct method for completing death certificates Methods: We reviewed 262 death certificates in three hospitals from March 1 to April 30, 2000, and 119 death certificates in one hospital from March 1 to 31, 2000. We identified major and minor errors and analyzed and compared them retrospectively. Results: A total of 381 death certificates were reviewed: 59 in Seoul National University Hospital,101 in Ewha Woman's University Hospital, and 102 in Gachon Medical College Hospital, which has no education program for completing death certificates in postgraduate training, and 119 in Samsung Medical Center which has an education program for completing death certificates. 358 certificates(94.0%) had at least one error. There were only 23 death certificates(6.0%) without an error. In 182 cases(47.8%), there was one major error. In 321 death certificates(84.3%), there were more than two errors. A comparison of Samsung Medical Center with the other hospitals showed that the number of total errors was statistically different(p=0.001). Conclusion: There were few death certificates without an error in this study. In a hospital which has postgraduate training in completing death certificates, there are fewer errors than in other hospitals which have no training course. Emergency physicians actually certify many deaths, so they must know the correct method of completing death certificates for statistics on morbidity and mortality.
Making Sense of the Trump Tariff: Evidence from the Exclusion Request
Yeo Joon Yoon(Yeo Joon Yoon) 한국APEC학회 2023 Journal of APEC Studies Vol.15 No.1
During the Trump administration, the United States invoked Section 301 of the Trade Act and imposed significant tariffs on Chinese imports. As a result, a large portion of Chinese goods were subject to additional tariffs. Concurrently, the U.S. administration introduced a trade remedy system called exclusion requests to minimize the damage inflicted on American companies that import goods from China. In this paper, we analyze the exclusion requests to shed light on the impact of the 301 tariffs. A thorough analysis on the exclusion requests would provide better understanding of the impact of Section 301 tariffs and Trump trade policy. The analysis revealed that when an exclusion request was made for products falling under HTS 84 or 85 that are also closely associated with “Made in China 2025”, the likelihood of approval significantly decreased.
Genetic dissection of the biosynthetic route to 4,6-Disubstituted Aminoglycoside
Yeo Joon Yoon 한국당과학회 2009 한국당과학회 학술대회 Vol.2009 No.1
Heterologous expression of different combinations of genes from the 4,6-disubstituted aminoglycoside biosynthetic gene cluster in a non-aminoglycoside producing strain of S. venezuelae caused production of intermediates from the biosynthetic pathway. This provided experimental evidence for assigning the functions of individual gene products and also allowed us to recognize a complete biosynthetic pathway for generation of 4,6-disubstituted aminoglycosides. This work has established an efficient heterologous expression platform based on a genetically amenable streptomycete to dissect the biosynthetic pathways of other aminoglycoside antibiotics produced by less tractable actinomycete.
