RESUMEN
The United Nations Secretary-General Mechanism (UNSGM) for investigation of the alleged use of chemical and biological weapons is the only established international mechanism of this type under the UN. The UNGSM may launch an international investigation, relying on a roster of expert consultants, qualified experts, and analytical laboratories nominated by the member states. Under the framework of the UNSGM, we organized an external quality assurance exercise for nominated laboratories, named the Disease X Test, to improve the ability to discover and identify new pathogens that may cause possible epidemics and to determine their animal origin. The "what-if" scenario was to identify the etiological agent responsible for an outbreak that has tested negative for many known pathogens, including viruses and bacteria. Three microbes were added to the samples, Dabie bandavirus, Mammarenavirus, and Gemella spp., of which the last two have not been taxonomically named or published. The animal samples were from Rattus norvegicus, Marmota himalayana, New Zealand white rabbit, and the tick Haemaphysalis longicornis. Of the 11 international laboratories that participated in this activity, six accurately identified pathogen X as a new Mammarenavirus, and five correctly identified the animal origin as R. norvegicus. These results showed that many laboratories under the UNSGM have the capacity and ability to identify a new virus during a possible international investigation of a suspected biological event. The technical details are discussed in this report.Copyright © 2022
RESUMEN
Purpose - This paper analyzes all possible issues that need to be considered in case disputes occur with regard to force majeure in international commercial contracts through the comparative study between English and Korean during COVID-19. Design/methodology - This paper belongs to the field of explanatory legal study, which aims to explain and test whether the choice of law is linked to the conditions that occur in the reality of judicial practice. The juridical approach involves studying and examining theories, concepts, legal doctrines, and legislation that are related to the problem. Findings - English law does not permit general economic impracticability to qualify as a valid force majeure event. If a party asserts that they were prevented from performing the contract, the courts will examine this strictly. Many commercial contracts in a broad range of sectors and industries are chosen by parties to be governed by English law. With COVID-19, there have been discussion of parties being released from performance as a result of force majeure. Meanwhile, under Korean law, a force majeure event should be unforeseeable and beyond a party's control. Since COVID-19 is a known event for future contracts, to avoid the risk that a similar situation in the future is deemed foreseeable and under a party's control, parties must ensure that such a risk is properly addressed in a contract. Therefore, it is necessary to have a new clause to cover a pandemic. Originality/value - In light of the ongoing unexpected and uncertain economic impacts COVID-19 is expected to bring to the world, it is anticipated that companies will experience an increased number of claims involving force majeure around the world, including English and Korea. As such, taking proactive steps to assess the applicable legal principles, including the concept of force majeure of contract, will help companies be prepared for the financial or legal implications of COVID-19. In this regard, it would be advisable for companies and businesses to take specific actions.
RESUMEN
Purpose - This study carried out an empirical study of the impact of sustainability - which has been gaining attention as challenges are arising in supply chains based on existing trade networks due to the impact of the COVID-19 pandemic - on SCM performance and financial performance of Korean SMEs. The study seeks to propose a measurement model to enhance the SCM performance and financial performance of Korean SMEs and to identify the relationship between sustainability, SCM performance and financial performance to suggest implications to SMEs, governments, and relevant organizations. Design/methodology - Our Analysis established hypotheses that economic sustainability, environmental sustainability, and other factors related to sustainability have a positive impact on SCM performance and financial performance as well as SCM performance has a positive impact on financial performance, making empirical validations by utilizing Structural Equation Modeling based on data collected through survey from Korean SMEs. Findings - According to an empirical study, although environmental sustainability and economic sustainability among factors of sustainability had a positive influence on SCM performance, social sustainability did not have a statistically significant influence. Furthermore, it was learned that only economic sustainability had a positive influence on financial performance while SCM performance has a positive influence on financial performance. Originality/value - This empirical study explored the relationship between SCM performance and financial performance of Korean SMEs with a high tendency to depend on specific supply chains when the international trade network is in confusion and/or the global supply chain has collapsed. If Korean SMEs allocate management resources to the factors deducted from this study, they would be able to build more efficient supply chains and improve financial performance to improve sustainability.
RESUMEN
Purpose - This study aims to analyze the characteristics of network construction by Norwegian Air and AirAsia X, which are recognized as leading airlines in the long-haul LCC market. Based on this analysis, this study intends to provide implications for networking strategies for Korean LCCs that seek to enter the long-haul market when the aviation market stabilizes again upon the end of the COVID-19 pandemic. Design/methodology - To conduct the network analysis on long-haul low-cost airlines, the Official Airline Guide (OAG) Schedule Analyzer was used to extract long-haul data of Norwegian Air and AirAsia X. To analyze the trend of the long-haul route network, we obtained the data from 3 separate years between 2011 and 2019. The network was analyzed using UCINET 6.0 in order to examine the network structure of long-haul low-cost airlines and the growth trend of each stage. Findings - Analyzing the network of long-haul routes by visualizing the network structure of low-cost carriers showed the following results. In its early years, Norwegian Air's long-haul route network, centering on regional airports in Spain and Sweden, connected European regions, the Middle East, and Africa. As time passed, however, the network expanded and became steadily strong as the airline connected airports in other European countries to North America and Asia. In addition, in 2011, AirAsia X showed links to parts of Europe, such as London and Paris, the Middle East and India, and Australia and Northeast Asia, centering on the Kuala Lumpur Airport. Although the routes in Europe were suspended, the network continued to expand while concentrating on routes of less than approximately 7,000 km. It was found that instead of giving up on ultra-long-haul routes such as Europe, the network was further expanded in Northeast Asia, such as the routes in Korea and Japan centering on China. Originality/value - Until the COVID-19 pandemic broke out, Norwegian Air actively expanded long-haul routes, resulting in the number of long-haul routes quintupling since 2011. The unfortunate circumstance, wherein the world aviation market was rendered stagnant due to the outbreak of COVID-19, hit Norwegian Air harder than any other low-cost carriers. However, in the case of AirAsia X, it was found that it did not suffer as much damage as Norwegian Air because it initially withdrew from unprofitable routes over 7,000 km and grew by gradually increasing profitable destinations over shorter distances. When the COVID-19 pandemic ends and the aviation market stabilizes, low-cost carriers around the world, including Korea, that enter the long-haul route market will need to employ strategies to analyze the marketability of potential routes and to launch the routes that yield the highest profits without being bound by distance. For stable growth, it is necessary to take a conservative stance;first, by reviewing the business feasibility of the operating a small number of highly profitable routes, and second, by gradually expanding these routes.
RESUMEN
Due to COVID-19 pandemic, wearing a mask rapidly becomes a new social norm that people in the society should comply. Although it is altruistic behavior preventing all people from serious infections, it brings about hassles for individuals. For example, when a face is partly covered with a mask, identification using a face recognition is going to be malfunctioning. To this end, we propose a novel computational framework that enables the personal authentication with a partial face image, a face covered with a mask. For the experiments, we constructed the datasets of facial images containing the periocular regions only, extracted from full facial images covered with the mask. Given the datasets, we trained our framework, a variant of a Siamese network, with various configuration of hyper-parameters. As a result, RMSprop optimizer with the learning rate 1 × 10–5 trained from periocular datasets showed the highest accuracy for the personal authentication. Next, we conducted a comparative experiment with our proposal and the model trained with datasets containing the full facial regions. When testing with the periocular region images, our proposal is superior in the authentication accuracy to that of the model trained with the full facial regions. This result raises the optimistic expectation that in the era of COVID-19, facial images covered with mask can still be used for the authentication using face recognition at a nearly same level of accuracy. This means that people can use the face recognition applications without taking off the mask, which provides the safe circumstances against the infections. © 2021, Springer Nature Switzerland AG.
