Nosocomial transmission of COVID-19 among immunocompromised hosts can have a serious impact on COVID-19 severity, underlying disease progression and SARS-CoV-2 transmission to other patients and healthcare workers within hospitals. We experienced a nosocomial outbreak of COVID-19 in the setting of a daycare unit for paediatric and young adult cancer patients. Between 9 and 18 November 2020, 473 individuals (181 patients, 247 caregivers/siblings and 45 staff members) were exposed to the index case, who was a nursing staff. Among them, three patients and four caregivers were infected. Two 5-year-old cancer patients with COVID-19 were not severely ill, but a 25-year-old cancer patient showed prolonged shedding of SARS-CoV-2 RNA for at least 12 weeks, which probably infected his mother at home approximately 7–8 weeks after the initial diagnosis. Except for this case, no secondary transmission was observed from the confirmed cases in either the hospital or the community. To conclude, in the day care setting of immunocompromised children and young adults, the rate of in-hospital transmission of SARS-CoV-2 was 1.6% when applying the stringent policy of infection prevention and control, including universal mask application and rapid and extensive contact investigation. Severely immunocompromised children/young adults with COVID-19 would have to be carefully managed after the mandatory isolation period while keeping the possibility of prolonged shedding of live virus in mind.

The genus Vicia L., one of the earliest domesticated plant genera, is a member of the legume tribe Fabeae of the subfamily Papilionoideae (Fabaceae). The taxonomic history of this genus is extensive and controversial, which has hindered the development of taxonomic procedures and made it difficult to identify and share these economically important crop resources. Species identification through DNA barcoding is a valuable taxonomic classification tool. In this study, four DNA barcodes (ITS2, matK, rbcL and psbA-trnH) were evaluated on 110 samples that represented 34 taxonomically best-known species in the Vicia genus. Topologies of the phylogenetic trees based on an individual locus were similar. Individual locus-based analyses could not discriminate closely related Vicia species. We proposed a concatenated data approach to increase the resolving power of ITS2. The DNA barcodes matK, psbA-trnH and rbcL were used as an additional tool for phylogenetic analysis. Among the four barcodes, three-barcode combinations that included psbA-trnH with any two of the other barcodes (ITS2, matK or rbcL) provided the best discrimination among Vicia species. Species discrimination was assessed with bootstrap values and considered successful only when all the conspecific individuals formed a single clade. Through sequencing of these barcodes from additional Vicia accessions, 17 of the 34 known Vicia species could be identified with varying levels of confidence. From our analyses, the combined barcoding markers are useful in the early diagnosis of targeted Vicia species and can provide essential baseline data for conservation strategies, as well as guidance in assembling germplasm collections.

Summary
Relevant legislation and statutory standards
The primary competition legislation in Korea is the Monopoly Regulation and Fair Trade Law (the FTL), which was enacted in April 1980. The FTL contains various sections which regulate particular aspects of competitive behaviour of companies. As major examples, the FTL regulates and covers, among other things, the following areas of activity:
monopolies, monopolisation and abuse of monopolistic power in general;
unfair collaborative activity;
business combination, including mergers and acquisitions; and
unfair trade practices.
Decision-making bodies and enforcement authority(ies)
The main competition authority in Korea is the Korea Fair Trade Commission (KFTC), which is authorised under the FTL to oversee the enforcement of that legislation. Among other things, the KFTC is involved in formulating and administering competition policy in Korea. It also deliberates, decides and handles competition cases through its decision-making process.
The KFTC consists of a committee (‘the Committee’), which is a decision-making body, and a secretariat (‘the Secretariat’), which is an administering body. There are currently nine commissioners in the Committee, ive of whom are government oficials (including the Chairman and Vice-Chairman of the KFTC and three standing commissioners) and four of whom are non-standing. The Secretariat performs activities such as investigating competition issues and enforcing decisions made by the Committee.

The FTL contains various sections which regulate particular aspects of competitive behavior of companies. As major examples, the FTL regulates and covers, among others, the following areas of activity:

Unfair trade practices.
Decision-making bodies and enforcement authority(ies)
The main competition authority in Korea is the Korea Fair Trade Commission (“KFTC”), which is authorised under the FTL to oversee the enforcement of that legislation. Among other things, the KFTC is involved in formulating and administering competition policy in Korea. It also deliberates, decides and handles competition cases through its decision-making process.
The KFTC consists of a committee (the “Committee”), which is a decision-making body, and a secretariat (the “Secretariat”), which is an administering body. There are currently nine commissioners in the Committee, five of whom are government officials (including the Chairman, the Vice-Chairman of the KFTC and three standing commissioners) and four of whom are non-standing. The Secretariat performs activities such as investigating competition issues and enforcing decisions made by the Committee.
When a competition issue potentially violating the FTL is brought to the KFTC's attention either by complaints filed by a competitor, customer, consumers or any other person, or at its own initiative, officials of the KFTC, who are mainly responsible for fact-finding, perform their investigation and submit a report of their findings to the Committee.
