The COVID-19 pandemic has affected many aspects of human life. The pandemic not only caused millions of fatalities and problems but also changed public sentiment and behavior. Owing to the magnitude of this pandemic, governments worldwide adopted full lockdown measures that attracted much discussion on social media platforms. To investigate the effects of these lockdown measures, this study performed sentiment analysis and latent Dirichlet allocation topic modeling on textual data from Twitter published during the three lockdown waves in Malaysia between 2020 and 2021. Three lockdown measures were identified, the related data for the first two weeks of each lockdown were collected and analysed to understand the public sentiment. The changes between these lockdowns were identified, and the latent topics were highlighted. Most of the public sentiment focused on the first lockdown as reflected in the large number of latent topics generated during this period. The overall sentiment for each lockdown was mostly positive, followed by neutral and then negative. Topic modelling results identified staying at home, quarantine and lockdown as the main aspects of discussion for the first lockdown, whilst importance of health measures and government efforts were the main aspects for the second and third lockdowns. Governments may utilise these findings to understand public sentiment and to formulate precautionary measures that can assure the safety of their citizens and tend to their most pressing problems. These results also highlight the importance of positive messaging during difficult times, establishing digital interventions and formulating new policies to improve the reaction of the public to emergency situations.

This qualitative study analyzed various environmental factors and difficulties faced by school foodservices during the COVID-19 pandemic. Focus group interviews were conducted by enrolling 12 nutrition teachers and nutritionists. Data collected were subsequently analyzed for changes implemented during the pandemic, in hygiene management, diet management, and distribution management of the school meal. The content and method of delivery of information related to diet guidance and school foodservice by related organizations were also examined. Results of the survey show that personal hygiene (such as maintaining student-to-student distance, checking students for a fever, and hand disinfection) was duly applied, installation of table coverings and distancing between school cafeteria seats were conducted, and mandatory mask-wearing to prevent droplet transmission was enforced. Depending on the COVID-19 situation, the number of students having school meals was limited per grade, and time-spaced meals were provided. To prevent infection, menus that required frequent hand contact were excluded from the meal plan. Overall, it was difficult to manage the meal plan due to frequent changes in tasks, such as the number of orders and meal expenses. These changes were communicated by nutrition teachers and nutritionists wherein the numbers of school meals were adjusted, depending on situations arising from each COVID-19 crisis stage. Furthermore, in some schools, either face-to-face nutrition counseling was stopped entirely, or nutrition education was conducted online. Parent participation was disallowed in the monitoring of school meals, and the prohibition on conversations inside the school cafeteria resulted in the absence of communication among students, nutrition teachers, and nutritionists. Additionally, confusion in meal management was caused by frequent changes in the school meal management guidelines provided by the Office of Education and the School Health Promotion Center in response to COVID-19. In anticipation of the emergence of a new virus or infectious diseases caused by mutations in the years to come, it is suggested that a holistic, well-thought-out response manual for safe meal operation needs to be established, in close collaboration with schools and school foodservice-related institutions.

Objectives: The study aim was to identify changes in the nutritional status of older adults during the COVID-19 pandemic according to household income and demographic characteristics. Methods: Study participants were 2,408 adults aged 65 and over who participated in the 2019-2020 Korea National Health and Nutrition Examination Survey (KNHANES). To examine changes in nutrient intake levels resulting from COVID-19, data of 2019 and of 2020 were compared. Study participants were divided into three groups based on household income level to compare these changes. The changes were compared according to household income level, age group, and household type. Results: Percentages of recommended intakes for energy, protein, and most micronutrients were the lowest for the low-income group of both males and females in 2020. The Mean Adequacy Ratio (MAR) score was the lowest for the low-income group in both years. When comparing nutrient density for 2019 and 2020 by income group, the male low-income group experienced a decrease in nutrient densities of vitamin A, thiamine, calcium, and iron. For the same group, a decreased percentage for energy intake from protein was noted. Fruit intake was lowest in the low-income group for both males and females. Low-income males had the lowest intake levels for meat, fish, eggs, and legumes in both 2019 and 2020 and the lowest milk and milk product intake levels in 2020. Older adults living alone or single older adults with children had lower MAR scores than those living with a spouse. Older adults living alone experienced decreases in energy and thiamine and iron intake levels in 2020 compared to their intake levels in 2019. Conclusions: Because of the COVID-19 pandemic, nutrition intake levels worsened for older adult males in the low-income group and older adults living alone. This finding shows the need for a more systematic nutritional support strategy for the vulnerable older adults population in national disaster situations.

The outbreak of COVID-19, caused by SARS-CoV-2 infection, has spread worldwide and resulted in a pandemic for health systems. The disease is transmitted via respiration as droplets or aerosol. Due to the nature of dental treatment, aerosols, including body fluid, blood, and saliva, are frequently produced in dental hospitals. The present study investigated the potential risk of nosocomial infection of COVID-19 in dental hospitals to provide recommendations in clinical situations. The Seoul National University Dental Hospital in Korea established a countermeasure to cope with the clinical situation based on The Guidelines of Korean Centers for Disease Control & Prevention (KCDC) for dental practitioners and the available literature. Notably, numerous considerations for patient reservation and schedule management are required for space separation in the hospital, including infection control. Experiences in dental hospitals in Korea would be referable for other dental hospitals facing this infectious respiratory disease.

Purpose: This study aimed to identify the mediating and moderating effects of mindset and psychological collectivism, respectively, on the relationship between grit and nursing intention for children with emerging infectious diseases, including coronavirus disease 2019 (COVID-19), among pediatric nurses. Methods: We conducted a cross-sectional descriptive study with 230 pediatric nurses. Results: Grit directly impacted mindset (β=.27, p<.001) and nursing intention (β=.20, p=.001). The direct effect of mindset on nursing intension (β=.28, p<.001) and the indirect effect of grit on nursing intension via mindset (β=.08, p<.001) were significant. Accordingly, mindset mediated the effect of grit on nursing intention. The effects of grit and psychological collectivism (β=.19, p=.003), respectively, on nursing intention were significant. However, the interaction between grit and psychological collectivism was not significant. Thus, psychological collectivism did not moderate the effect of grit on nursing intention. Conclusion: The findings demonstrate the importance of pediatric nurses' grit and mindset on their intended care for patients in critical situations. Cultivating a gritty culture and developing interventions to enhance nurses' personality traits associated with their performance will be crucial, and such measures are especially salient for pediatric nurses to face the new adjustments required in the era of COVID-19.

Purpose: The COVID-19 pandemic has increased the importance of nurses' clinical performance, and accordingly, nursing educators have emphasized students' clinical practice and performance. This study developed a Clinical Practice Self-Efficacy Scale for nursing students and examined its psychometric properties. Methods: The authors reviewed instruments for selecting items for the scale in the areas of clinical skills, communication, infection control, safety, and nursing process. After preliminary items were selected, ten experts consisting of nursing professors and clinical nurses reviewed the items considering Korean clinical and educational situations. The data for the psychometric evaluation was collected from 257 nursing students in their 2nd, 3rd, and 4th years and then analyzed. Results: The confirmatory factor analysis showed that the goodness of fit of this scale with five factors represented by 40 items was appropriate. The significant positive correlations with general self-efficacy indicated sound construct validity. The senior nursing students showed higher scores than others, as we expected. Cronbach's alpha was .94. Conclusion: The Clinical Practice Self-Efficacy Scale is appropriate for measuring Korean nursing students' self-efficacy of clinical practice. It is expected to act as a good tool to measure the effects of clinical practice education.
