Purpose : The first case of coronavirus disease-2019 (COVID-19) disease outbreak in Korea occurred in January 2020, and the cumulative number of confirmed cases by the Central Defense Response Headquarters of the Quality Management Administration as of November 30 was 34,201. Looking at the incidence trend of domestic confirmed cases by age, the incidence rate of COVID-19 in the age group of 20-29 years, which corresponds to college students, was 27.4 %, the highest compared by age group. Considering the current status of the infection rate, universities will become the centers of new COVID-19 cases if face-to-face lectures are recommenced without preparatory measures and analysis of infection prevention (e.g., infection awareness and education for university students). Thus, this study intended to investigate the level of knowledge, educational needs, and preventive behavior performance of college students about COVID-19 and provide basic data for the development of an education program for the prevention of COVID-19 for college students. Methods : This study is a descriptive correlational study aimed to investigate the correlation between knowledge about COVID-19, educational needs, and degree of preventive behavior performance in 407 college students attending one University in Gyeonggi-do. Results : The subjects' knowledge score about COVID-19 was 12.46±1.39 points, average educational needs score was 29.16±3.14 points, and prevention behavior performance survey result was 35.50±3.61 points. Moreover, positive correlation was observed between the knowledge about COVID-19 and educational needs (r=.203, p<.001) and knowledge and preventive behavior performance (r=.140, p=.005). Further, educational needs and preventive behavior performance demonstrated a statistically significant positive relationship (r=.311, p<.001). Conclusion : Therefore, organizing an educational program to acquire accurate knowledge is necessary to make it a habit for college students to practice preventive behavior against COVID-19.

After the outbreak of the SARS-CoV2 virus that causes COVID-19, it spreads around the world with the number of infections and deaths rising rapidly caused a shortage of medical resources. As a way to solve this problem, chest X-ray diagnosis using Artificial Intelligence(AI) received attention as a primary diagnostic method. The purpose of this study is to comprehensively analyze the detection of COVID-19 via AI. To achieve this purpose, 292 studies were collected through a series of Classification methods. Based on these data, performance measurement information including Accuracy, Precision, Area Under Cover(AUC), Sensitivity, Specificity, F1-score, Recall, K-fold, Architecture and Class were analyzed. As a result, the average Accuracy, Precision, AUC, Sensitivity and Specificity were achieved as 95.2%, 94.81%, 94.01%, 93.5%, and 93.92%, respectively. Although the performance measurement information on a year-on-year basis gradually increased, furthermore, we conducted a study on the rate of change according to the number of Class and image data, the ratio of use of Architecture and about the K-fold. Currently, diagnosis of COVID-19 using AI has several problems to be used independently, however, it is expected that it will be sufficient to be used as a doctor's assistant.

Purpose: This study aimed to identify the mediating effect of Psychological stress of COVID-19 stress on the relationship between nursing work environment and turnover intention of nurses in long-term care hospitals. Methods: The participants were 176 nurses working at three long-term care hospitals in Changwon City. Data were collected from August 11 to 14, 2021, using self-report questionnaires. The data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients, and hierarchical regression, using the SPSS 23.0 software. A mediation analysis was performed according to the Baron and Kenny's test, and Sobel test. Results: Turnover intention was positively correlated with Psychological stress of COVID-19 stress (r=.23, p=.002) and negatively correlated with nursing work environment (r=-.44, p<.001). Psychological stress of COVID-19 stress had a significantly negative relationship with nursing work environment (r=-.15, p=.045). Psychological stress of COVID-19 stress partially mediated the relationship between nursing work environment and turnover intention. Conclusion: The findings of this study indicate that a positive nursing work environment can help nurses reduce their Psychological stress of COVID-19 stress and turnover intention. To reduce the turnover intention among nurses' in long-term care, it is necessary to promote better work environments suitable for COVID-19 and to establish detailed strategies for reducing their physiological stress.

Purpose: Uncertainty and restrictions on daily life have increased fear, stress, and depression during the coronavirus disease 2019 (COVID-19) pandemic. Depression is the most common mental health problem in pregnant women. The purpose of this study was to evaluate the levels of fear and stress related to COVID-19 experienced by pregnant women, as well as their levels of depression, and to examine the factors associated with depression during pregnancy. Methods: This was a cross-sectional, correlational study conducted among 153 pregnant women who visited a maternity hospital in Busan, South Korea. A self-reported questionnaire was used for data collection from December 18, 2021 to March 8, 2022. Data were analyzed using descriptive statistics, the independent t-test, one-way analysis of variance, Pearson correlation coefficients, and multiple regression. Results: Pregnant women experienced a moderate level of fear related to COVID-19, with an average score of 21.55±4.90. The average score for depression during pregnancy was 14.86±11.10, with 50.3% of the participants experiencing depression (≥13). The factors associated with depression during pregnancy were fear of COVID-19, contact with a confirmed case of COVID-19, being in the third trimester of pregnancy, high stress levels due to difficulties experienced from social distancing measures, and unintended pregnancy. These five statistically significant factors explained 35.0% of variance in depression during pregnancy. Conclusion: Considering the prevalence of depression in pregnant women during the COVID-19 pandemic, it is necessary to develop interventions to reduce anxiety by providing correct information and alleviating the stress of social distancing.

Purpose: In response to the surge in coronavirus disease 2019 (COVID-19) omicron variant cases, we have implemented preemptive testing for preschool and school. The purpose is to quickly detect COVID-19 cases using a rapid antigen test (RAT) kit so that normal school activities can continue. Methods: The results entered in The Healthcare Self-Test App were merged with the information on the status of confirmed cases in the COVID-19 Information Management System by Korea Disease Control and Prevention Agency (KDCA) for preschool and school of students and staffs March 2 to May 1, 2022 to analyze the RAT positive rate and positive predictive value of RAT. Results: In preschool and school 19,458,575 people were tested, weekly RAT positive rate ranged from 1.10% to 5.90%, positive predictive value of RAT ranged from 86.42% to 93.18%. By status, RAT positive rate ranged from 1.13% to 6.16% for students, 0.99% to 3.93% for staffs, positive predictive value of RAT ranged from 87.19% to 94.03% for students, 77.55% to 83.10% for staffs. RAT positive rate by symptoms ranged from 76.32% to 88.02% for those with symptoms and 0.34% to 1.11% for those without symptoms. As a result of preschool and school RAT, 943,342 confirmed cases were preemptively detected, before infection spread in preschool and school. Conclusions: RAT was well utilized to detect confirmed cases at an early stage, reducing the risk of transmission to minimize the educational gap in preschool and school. To compensate for the limitations of RAT, further research should continue to reevaluate the performance of RAT as new strains of viruses continue to emerge. We will have to come up with various ways to utilize it, such as performing periodic and repeated RAT and parallel polymerase chain reaction.

Currently, virus infection such as Corona 19 has become commonplace, and interest in unmanned systems is increasing in the field for non-face-to-face ICT services. In this paper, the function and performance of remotely successfully controlling a store through video and audio using an IP PBX with a broadcasting function was verified through a test. And the fully unmanned system is not gaining credibility due to various technical problems, however the central control system is a very efficient and reliable system because the controller can directly control the customer while monitoring the access and the inside of the store through the video and audio. In the future, we plan to study a completely unmanned remote control system using A.I technology.

Purpose: The purpose of this qualitative study is to explore the changed parenting experiences of mothers of elementary school kids living in the aftermath of the COVID-19 outbreak in Korea. Methods: From July to August in 2020, 10 mothers parenting elementary school students under the COVID-19 were interviewed in depth. For data analysis, a phenomenological research methodology suggested by Colaizzi was used. Results: According to the analysis, the experiences of mothers consisted of four categories: the 'pain from the uncontrollable COVID-19', 'the problem of family relations due to the COVID-19 pandemic situation', 'standing firm against the drastic changes', and 'accepting the world changed by the COVID-19'. Conclusion: The findings in this study vividly represent the parenting experiences of mothers of elementary school students after the outbreak of COVID-19. As the pandemic persists, mothers parenting elementary school students feel complex emotions and experience exhaustion, but in the process, they found family members growing positively and trying to adjust to each other to overcome the crisis. To support positive adaptation to catastrophic situations, an institutional and political foundation is needed to develop a systematic crisis management program customized for mothers and families of elementary school students. The results of this study can be used as basic data when establishing national policies and support systems so that mothers parenting elementary school students can better adapt to and overcome crisis situations.

In this paper, we propose a crucial issue to require further management plan for Korean hospital nurses in burnout during COVID-19 pandemic. The purpose of this study was to conduct a systematic review of factors related to hospital nurses in burnout for the COVID-19 outbreak. Appropriate studies in the recent three years were selected from database. To perform a systematic review, the databases of RISS, KISS, DBPIA, and Kyobo scholar were searched using the key words, 'nurse in burnout' or 'burnout for nurse'. Fifty-five references were checked, but only seven studies were decided inclusion criteria to review. It was founded that Korean hospital nurses felt moderate or higher burnout level for COVID-19 pandemic. We were confirmed that related factors of hospital nurses in burnout were personal characteristics, physical symptom, depression, compassion satisfaction, compassion fatigue, and resilience, and occupational characteristics, shift work and job stress. It may be necessary to provide regulating programs for hospital nurses in burnout and to set up a policy and guidelines so as to reduce burnout of nurses working.
