Purpose: The coronavirus disease 2019 (COVID-19) pandemic has significantly disrupted cancer screening services worldwide. We aimed to measure the impact of COVID-19 on gastric cancer screening rates based on age, sex, household income, and residential area. Materials and Methods: We analyzed data from the Korean National Cancer Screening Survey from 2017 to 2021 for adults aged 40-74 years. We evaluated the gastric cancer screening rate within two years in accordance with the National Cancer Screening Program protocol recommendations and that within the previous year. We compared the trends in the pre- and post-COVID-19 outbreak periods. Results: Before the COVID-19 outbreak, there was little change in the gastric cancer screening rates until 2019. After the COVID-19 outbreak, the screening rate as per recommendation decreased from 70.8% in 2019 to 68.9% in 2020 and that for one year decreased from 32.7% in 2019 to 27.2% in 2020. However, as the COVID-19 pandemic continued after 2020, both gastric cancer screening rates as per recommendations and for one year rebounded. Although a similar trend was observed for the upper endoscopy screening rate, the upper gastrointestinal series screening rate decreased from 7.8% in 2020 to 3.1% in 2021. During the pandemic, the screening rate decreased among younger adults (40-49), those residing in metropolitan regions, and those with high incomes. Conclusions: Despite a decline in gastric cancer screening rate during the COVID-19 pandemic, the rate surged in 2021. Further studies are needed to estimate the impact of cancer screening delays on future cancer-related mortalities.

On-line learning has been adopted as a major educational method due to the COVID-19 pandemic. Students and faculties got accustomed to on-line educational environment as they experienced it during the COVID-19 pandemic. Development of various technologies and social requirement for educational renovation lay groundwork for on-line learning as well. Therefore, on-line learning or blended learning will be likely to go on after the end of COVID-19 pandemic and it is necessary to prepare the guidelines for effective utilizing on-line learning. The primary purpose of this study is to examine the learning behaviors and the learning effects by using LMS data. Learning behaviors were measured in terms of learning time and access frequency for pre-recorded video lectures targeting computer-practice classes. The results of empirical analysis reveal that frequency was the significant predictor of course achievements but learning time was not. The findings of empirical analysis will provide insights that the effective planning and designing on-line classes based on learning behaviors are key to enhancing learning effects and learner's satisfaction.

Background: Dental hygienists are crucial in managing infection control within dental clinical settings. This study focused on examining the pre-treatment infection control practices (PT-PRF_IC) of Korean dental hygienists in the context of coronavirus disease (COVID-19) and identifying factors influencing their implementation levels. Methods: An online, self-administered survey was conducted with 263 dental hygienists working in dental hospitals or clinics. The survey explored various aspects such as the experience with infection control education (Edu_IC), PT-PRF_IC, and the types of surface disinfectants used. Additionally, data from previous studies on the knowledge level of COVID-19 (KNW_CO), infection control awareness level (AWR_IC), infection control performance level (PRF_IC), and infection control organizational factor (OFW_IC) were utilized. Statistical analyses included t-tests, one-way ANOVA, chi-square tests, Pearson correlation, and multiple linear regression. Results: The study identified variations in PT-PRF_IC based on the number of dental hygienists within an organization. Differences in Edu_IC were observed concerning age, number of years worked, and monthly pay. The OFW_IC had the most substantial impact on PT-PRF_IC, followed by PRF_IC, and AWR_IC. Conclusion: To improve compliance with PT-PRF_IC, it is essential to consider a combination of factors including OFW_IC, PRF_IC, and AWR_IC. Strengthening organizational factors and awareness can enhance infection control practices and prevent COVID-19 transmission during dental care.

Background: PTSD (Post-traumatic stress disorder, PTSD) had a great impact on health care workers during the COVID-19 (Corona Virus Disease 2019, COVID-19). Better knowledge of the prevalence of PTSD and its risk factors is a major public health problem. This study was conducted to assess the prevalence and important risk factors of PTSD among medical staff during the COVID-19. Methods: The databases were searched for studies published during the COVID-19, and a PRISMA (preferred reporting items for systematic review and meta-analysis) compliant systematic review (PROSPERO-CRD 42021278970) was carried out to identify articles from multiple databases reporting the prevalence of PTSD outcomes among medical staff. Proportion random effect analysis, I² statistic, quality assessment, subgroup analysis, and sensitivity analysis were carried out. Results: A total of 28 cross-sectional studies and the PTSD results of doctors and nurses were summarized from 14 and 27 studies: the prevalences were 31% (95% CI [confidence interval, CI]: 21%-40%) and 38% (95% CI: 30%-45%) in doctors and nurses, respectively. The results also showed seven risks (p < 0.05): long working hours, isolation wards, COVID-19 symptoms, nurses, women, fear of infection, and pre-existing mental illness. Two factors were of borderline significance: higher professional titles and married. Conclusion: Health care workers have a higher prevalence of PTSD during COVID-19. Health departments should provide targeted preventive measures for medical staff away from PTSD.

Background: This study aims to identify the safety and health risk perceptions toward the coronavirus disease-2019 (COVID-19) pandemic based on gender in Korean university students who work and study during the pandemic. Methods: A nationwide convenient sampling method was implemented to eliminate any regional characteristics in 757 university students, including those who studied while working. The participants answered the online questionnaire for one week. The collected data were analyzed using the R version 3.4.1 program. Results: The results comparing the safety and health risk perceptions toward COVID-19 based on the gender of the subjects who work while studying, "I often use the Internet to obtain information on COVID-19 infection control" are females appeared to use the internet more often (t = -2.18, p = 0.031) than males. "Compared to pre-COVID-19, I am currently feeling safe after the outbreak" is females felt less safe (t = 3.43, p < 0.001). Although COVID-19 infection control awareness is high among Korean university students and officials, males reported higher scores over females in all the questions, which was statistically significant. Conclusion: There should be prioritized psychological measures for prevention against COVID-19 for vulnerable groups with high mental health risks. A network must be established to protect the mental health of such groups, and candidates who require intervention must be actively identified and supported. Therefore, there must be efforts to deliver accurate information based on scientific evidence of the infectious disease, and the actions should be supported through such active communication.

This study examined the determinants of healthy food purchases before and after COVID-19 in Korea. Binomial and multinomial logistic regression models were applied to Korea Rural Economic Institute's Food Consumer Behavior Survey data from 2019 to 2021. The analysis revealed a significant decrease in the non-intake of healthy food in 2021 compared to 2019, suggesting the impact of COVID-19 on healthy food consumption. Consumption patterns also changed, with a decrease in direct purchases and an increase in gift-based purchases. Several variables showed significant effects on healthy food intake. Single-person households exhibited a higher probability of eating healthy food after COVID-19. The group perceiving themselves as healthy had a lower likelihood of consuming healthy food pre-COVID-19, but this changed after the pandemic. Online food purchases, eco-friendly food purchases, and nut consumption showed a gradual decrease in the probability of non-intake over time. Gender and age also influenced healthy food intake. The probability of eating healthy food increased in the older age group compared to the younger group, and the probability increased significantly after COVID-19. The probability of buying gifts was significantly higher in those in their 60s, indicating that the path to obtaining healthy food differed by age.

During the past two decades, the Southeast Asian region has experienced a range of major crises. Service industries such as tourism and the marginal and migrant laborers who work in them have usually been at the sharp end of these testing events, from natural and environmental disasters, epidemics and pandemics, global financial slumps, terrorism, and political conflict. The latest challenge is the "Novel Coronavirus" (Covid-19/SARS-CoV-2) pandemic. It has already had serious consequences for Southeast Asia and its tourism development and these will continue for the foreseeable future. Since the SARS epidemic of 2002-2004, Southeast Asian economies have become integrated increasingly into those of East Asia (China, Japan, South Korea, Taiwan, Hong Kong). This paper examines one of the most significant current crises, Covid-19, and its consequences for Southeast Asia, its tourism industry, and its workers, comparing experiences across the region, and the issues raised by the over-dependence of some countries on East Asia. In research on crises, the main focus has been on dramatic, unpredictable natural disasters, and human-generated global economic downturns. Not so much attention has been devoted to disease and contagion, which has both natural and socio-cultural dimensions in origins and effects, and which, in the case of Covid-19, evoke a pre-crisis period of normality, a liminal transition or "meantime" and a post-crisis "new normality." The transition is not straightforward; in many countries, it operates as a set of serial lockdowns and restrictions, and to predict an uncertain future remains difficult.

The outbreak of COVID-19 has significantly impacted various facets of individuals' lives, including perceptions, leisure activities, work-family balance, and overall life satisfaction. This study aims to explore the intricate relationships among changes in perceptions due to COVID-19, leisure activity satisfaction, work-family conflict, and life satisfaction of married working women. Employing path analysis, we examined a dataset of 1,973 married working women drawn from the 8th Korean Women and Families Panel Survey. The findings indicate that while changes in perception associated with COVID-19 did not directly affect leisure activity satisfaction and life satisfaction, they did significantly decrease work-family conflict, indirectly leading to heightened life satisfaction. Additionally, leisure activity satisfaction emerged as a mitigating factor for work-family conflict, contributing to enhanced life satisfaction. These results emphasize the importance of understanding the interplay between external factors, individual perceptions, and well-being, offering insights for devising tailored strategies. The study holds significance in guiding policies and interventions to enhance the quality of life for married working women in the context of evolving pandemic challenges.

Disease caused by the coronavirus (COVID-19) is sweeping the globe. There are numerous methods for identifying this disease using a chest imaging. Computerized Tomography (CT) chest scans are used in this study to detect COVID-19 disease using a pretrain Convolutional Neural Network (CNN) ResNet50. This model is based on image dataset taken from two hospitals and used to identify Covid-19 illnesses. The pre-train CNN (ResNet50) architecture was used for feature extraction, and then fully connected layers were used for classification, yielding 97%, 96%, 96%, 96% for accuracy, precision, recall, and F1-score, respectively. When combining the feature extraction techniques with the Back Propagation Neural Network (BPNN), it produced accuracy, precision, recall, and F1-scores of 92.5%, 83%, 92%, and 87.3%. In our suggested approach, we use a preprocessing phase to improve accuracy. The image was enhanced using the Contrast Limited Adaptive Histogram Equalization (CLAHE) algorithm, which was followed by cropping the image before feature extraction with ResNet50. Finally, a fully connected layer was added for classification, with results of 99.1%, 98.7%, 99%, 98.8% in terms of accuracy, precision, recall, and F1-score.
