This study shows that consumers' attitudes and behaviors are rapidly changing due to the COVID-19 outbreak in a situation where consumption patterns are already changing due to demographic changes such as an increase in the number of single-person households and dual-income couples. To this end, the results of an online survey conducted on 500 panels of Nielsen Korea were used in this study. In particular, consumers were divided into two generation groups (Generation Z vs. Millennial) and analyzed and presented changes in consumption activities and food purchasing behaviors changed by COVID-19. As a result, the existing online distribution trend has been strengthened, and its impact has been amplified by COVID-19. These changes also resulted in different consumption behaviors depending on the degree of concern for COVID-19 by generation. Based on the results of this study, it turns consumers' behavioral changes into new opportunities, focusing on the accelerating a new 'contactless' lifestyle, which will provide managerial implications for the food industry's response strategies in relation to the theoretical significance and in practice.

Background: In the absence of a vaccine or treatment, the most pragmatic strategies against an infectious disease pandemic are extensive early detection testing and social distancing. This study aimed to summarize public and workplace responses to Coronavirus Disease-19 (COVID-19) and show how the Korean system has operated during the COVID-19 pandemic. Method: Daily briefings from the Korean Center for Disease Control and the Central Disaster Management Headquarters were assembled from January 20 to May 15, 2020. Results: By May 15, 2020, 11,018 COVID-19 cases were identified, of which 15.7% occurred in workplaces such as health-care facilities, call centers, sports clubs, coin karaoke, and nightlife destinations. When the first confirmed case was diagnosed, the Korean Center for Disease Control and Central Disaster Management Headquarters responded quickly, emphasizing early detection with numerous tests and a social distancing policy. This slowed the spread of infection without intensive containment, shut down, or mitigation interventions. After entering the public health blue alert level, a business continuity plan was distributed. After entering the orange level, the Ministry of Employment and Labor developed workplace guidelines for COVID-19 consisting of social distancing, flexible working schedules, early identification of workers with suspected infections, and disinfection of workplaces. Owing to the intensive workplace social distancing policy, workplaces remained safe with only small sporadic group infections. Conclusion: The workplace social distancing policy with timely implementation of specific guidelines was a key to preventing a large outbreak of COVID-19 in Korean workplaces. However, sporadic incidents of COVID-19 are still ongoing, and risk assessment in vulnerable workplaces should be continued.

Objectives: This study aimed to verify the relations of COVID-19 infection-related knowledge, dental infection control performance, and psychosocial health of dental hygienists. Methods: From the data was analyzed through the frequency analysis, t-test, one way ANOVA, and pearson's correlation analysis with a total of 198 dental hygienists using SPSS Statistics 21.0. Results: The correct answer rate for knowledge about COVID-19 was higher with a bachelor's degree or higher. Thus, when the level of education was higher, the performance was also high (p<0.01). COVID-19 infection control performance was highly shown in case of high age (4.43) (p<0.05) and the married (4.42) (p<0.01). Infection control performance was high when they had an educational experience of COVID-19 infection control (4.46), and when the infection control guidebooks were equipped in their workplaces (p<0.001). Degree of psychosocial health of research subjects was shown in the order of potential stress (60.6%), high-risk stress (23.7%), and healthy (15.7%). Infection control performance was higher, the psychosocial health was healthy. Conclusions: For the response to COVID-19 infectious disease and the preparation for mutated viruses and new infectious diseases in the future, it would be necessary to establish the concrete measures for establishing the strict infection control system for dental clinics and also enhancing the psychosocial health of dental hygienists.

This study is aming at analysing the current trend of container shipping industry before and after COVID-19 Pandemic circumstances. Also, this study offers the political implications for 'the Korean Shipping Nation Rebuilding'. As a result of this study, the several global shipping lines have decreased their ship capacity in response to International Maritime Organization(IMO)'s environmental regulation. This finding is differ from the media reports, that is many shipping companies increased idling vessel to match the lower demand induced COVID-19 pandemic. This study also provides the two implications of the direction about Korean shipping policy. The first one is that the casual relationship of over-vessels' supply and Korea shipping policy is needed to be thoroughly analyzed. The importance of Koreans shipping industry is generally devaluated by most citizens so as to the Korean government should develop the mass media contents to enlighten the less wellknown people regarding shipping industry.

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is transmitted primarily through droplets, and dental practitioners are at risk of occupational exposure to SARS-CoV-2 infection owing to direct contact with the patient's mouth, aerosols from dental procedures, and saliva. Wearing a mask is believed to be the best method of protection against infection, and a systematic literature review was conducted on whether the dental masks used in dentistry are effective in preventing Coronavirus Infectious Disease-19 (COVID-19). Methods: We used PubMed, Google Scholar, DBpia, NDSL, and KISS databases for this study. Of the 917 documents narrowed down by the search terms "Coronavirus, COVID-19, and dental," 83 documents were collected and studied. Ultimately, 42 of these papers were selected for analysis after considering duplication from the flow chart of the literature selection process. Results: While dental masks are often used when treating patients with unknown COVID-19 status, the Ministry of Food and Drug Safety stated that the use of dental masks is insufficient in preventing cross-transmission of COVID-19; instead, it was recommended that N95 masks, which correspond to KF94 masks, should be worn daily. On the other hand, wearing a dental mask and following precautions such as hand hygiene may not pose a significantly higher risk of infection than wearing an N95 mask when treating COVID-19 patients. Conclusion: There is an ongoing discussion regarding the use of dental masks when treating dental patients, and many argue that different types of masks should be selected according to the degree of infection and the individual's respiratory condition. By considering the safety and efficacy of dental masks in preventing infection, improvements can be made in the management of COVID-19 and dental-related infections.

Purpose: The study was done to compare the status of dispatch of public officials in charge of health care in response to COVID-19 according to location of primary health care posts and the practitioners' knowledge, attitude and support related to COVID-19. Methods: Among the 193 practitioners surveyed, 175 people in Chungcheong-do, Jeolla-do and Gyeongsang-do were selected for final analysis according to work status and differences in knowledge, attitude and support. Data were analyzed using χ2 and one-way ANOVA, followed by a Scheffé-test. Results: There was a statistically significant difference by region in the number of days and places for dispatch teams to respond to COVID-19. In particular, in the case of support, the overall score was low, but Gyeongsang-do, which had the longest number of dispatch days due the occurrence of a large-scale confirmation of patients, showed higher support compared to other regions. Knowledge of COVID-19 was high, but there were no regional differences. Conclusion: Regarding performance of COVID-19 response tasks, the support level was low, indicating that psychological support and appropriate compensation from the local government are required. In addition, it is necessary to prepare a system for the provision of alternative services to prevent a work gap in health clinics.
