Purpose: We aimed to identify collaborative disaster governance through the demand and supply analysis of resources recognized by nurses during the COVID-19 pandemic., Methods: We used a descriptive study design with an online survey technique for data collection. The survey questions were developed based on focus group interviews with nurses responding to COVID-19 and expert validity testing. A 42-question online survey focusing on disaster governance was sent to nurses working in COVID-19 designated hospitals, public health offices, and schools. A total of 630 nurses participated in the survey. Demand and supply analysis was used to identify the specific components of disaster governance during a pandemic situation and analyze priority areas in disaster governance, as reported by nurses., Results: Demand and supply analysis showed that supplies procurement, cooperation, education, and environment factors clustered in the high demand and supply quadrant while labor condition, advocacy, emotional support, and workload adjustment factors clustered in the high demand but low supply quadrant, indicating a strong need in those areas of disaster governance among nurses. The nurses practicing at the public health offices and schools showed major components of disaster governance plotted in the second quadrant, indicating weak collaborative disaster governance., Conclusion: These findings show that there is an unbalanced distribution among nurses, resulting in major challenges in collaborative disaster governance during COVID-19. In the future and current pandemic, collaborative disaster governance, through improved distribution, will be useful for helping nurses to access more required resources and achieve effective pandemic response., Competing Interests: The authors declared no conflict of interest., (© 2021 Korean Society of Nursing Science.)

Purpose: This study aimed to identify the mediating effects of depression amid the influence of fear and social distancing arising from Coronavirus disease 2019 (COVID-19) in Korean women's suicidal ideation., Methods: A descriptive correlation study was conducted. Study participants, recruited by Hankook Research from March 2 to March 5, 2021, included 300 women aged 19 to 49 living in South Korea, and 100 people were randomly allocated and enlisted for each age group out of 700,000 Hankook Research Panels recruited in advance from 17 cities and provinces nationwide. Data were collected through a self-reported questionnaire and analyzed using Pearson's correlation coefficient and Hayes' Process Macro Model 4 with 95% bias-corrected bootstrap confidence interval via SPSS statistics 27.0., Results: Suicidal ideation was significantly correlated with fear of COVID-19 (r = .16, p = .006) and depression (r = .65, p < .001). The mediation effect of depression in the relationship between the fear of COVID-19 and suicidal ideation was found to be significant (B = 0.40, boot 95% CI: 0.21~0.61). However, social distancing did not significantly affect suicidal ideation via depression (B = -0.79, boot 95% CI: -1.94~0.26)., Conclusion: It is necessary to develop and apply interventions to prevent depression and suicidal behaviors by continuously observing and reducing the negative psychological responses caused by COVID-19., Competing Interests: The authors declared no conflict of interest., (© 2022 Korean Society of Nursing Science.)

Purpose: This study aimed to develop a situation-specific theory to explain nurses' experiences of the COVID-19 crisis., Methods: The participants were 16 hospital nurses who experienced the COVID-19 crisis. Data were collected through in-depth individual interviews from September 2, 2020 to January 20, 2021. Transcribed interview contents were analyzed using Corbin and Strauss's grounded theory method., Results: A total of 38 concepts and 13 categories were identified through an open coding process. The core category found was becoming a pioneering nurse who turns crises into opportunities. The causal conditions were the chaos of being exposed defenselessly to an unexpected pandemic, fear caused by a nursing care field reminiscent of a battlefield, and moral distress from failing to protect patients' human dignity. The contextual conditions were feeling like the scapegoat of the hospital organization, increasing uncertainty due to the unpredictable state of COVID-19, and relative deprivation due to inappropriate treatment. The central phenomenon was suffering alone while experiencing the dedication of the COVID-19 hero image. The action/interactional strategy were efforts to find a breakthrough and getting the nurse's mind right, and the intervening conditions were gratitude for those who care for broken hearts and getting used to myself with repetitive work. The Consequences were becoming an independent nurse and frustration with the unchanging reality., Conclusion: This study provides the foundation for the nurse's situation-specific theory of the COVID-19 crisis by defining the crisis perceived by nurses who cared for COVID-19 patients and suggesting types of coping with the crisis., Competing Interests: The authors declared no conflict of interest., (© 2021 Korean Society of Nursing Science.)

Coronavirus disease 19 (COVID-19) is an infectious disease and is currently a global pandemic. The disease presents mainly with respiratory symptoms, but a broad spectrum of extrapulmonary complications have also been reported in the cardiovascular, gastrointestinal, and nervous systems. Peripheral nerve injury associated with COVID-19 infections can be caused by direct viral invasion or secondary immune response to neural tissue with the same receptors as alveoli, but its clinical course is poorly understood. Anterior interosseous nerve syndrome is a pure motor neuropathy that causes paralysis of the flexor pollicis longus, the flexor digitorum profundus of the index finger, and the pronator quadratus muscles. The cause of this syndrome is not clearly understood, but may be related to viral infection, autoimmune response, or vaccination. This paper reported a case of partial recovery with conservative treatment in acute anterior interosseous nerve syndrome following COVID-19 infection. [ABSTRACT FROM AUTHOR]

This paper propose a clustered algorithm that possible more efficient COVID-19 disease learning prediction within clustering using context-aware attribute information. In typically, clustering of COVID-19 diseases provides to classify interrelationships within disease cluster information in the clustering process. The clustering data will be as a degrade factor if new or newly processing information during treated as contaminated factors in comparative interrelationships information. In this paper, we have shown the solving the problems and developed a clustering algorithm that can extracting disease correlation information in using K-means algorithm. According to their attributes from disease clusters using accumulated information and interrelationships clustering, the proposed algorithm analyzes the disease correlation clustering possible and centering points. The proposed algorithm showed improved adaptability to prediction accuracy of the classification management system in terms of learning as a group of multiple disease attribute information of COVID-19 through the applied simulation results.

Cyber-attacks such as smishing and hacking mail exploiting COVID-19, political and social issues, have recently been continuous. Machine learning and deep learning technology research are conducted to prevent any damage due to cyber-attacks inducing malicious links to breach personal data. It has been concluded as a lack of basis to judge the attacks to be malicious in previous studies since the features of data set were excessively simple. In this paper, nine main features of three types, “URL Days”, “URL Word”, and “URL Abnormal”, were proposed in addition to lexical features of URL which have been reflected in previous research. F1-Score and accuracy index were measured through four different types of machine learning algorithms. An improvement of 0.9% in a result and the highest value, 98.5%, were examined in F1-Score and accuracy through comparatively analyzing an existing research. These outcomes proved the main features contribute to elevating the values in both accuracy and performance. [ABSTRACT FROM AUTHOR]

With the advent of the Fourth Industrial Revolution, the paradigm of finance is also changing. As remote work becomes more active due to cloud computing and coronavirus, the work environment changes and attack techniques are becoming intelligent and advanced, companies should accept new security models to further strengthen their current security systems. Zero trust security increases security by monitoring all networks and allowing strict authentication and minimal access rights for access requesters with the core concept of doubting and not trusting everything. In addition, the use of NAC and EDR for identification subjects and data to strengthen access control of the zero trust-based security system, and strict identity authentication through MFA will be explained. Therefore, this paper introduces a zero-trust security solution that strengthens existing security systems and presents the direction and validity to be introduced in the financial sector.

Even the announcing date for the staring date of “With Corona” has been decided, still many people have not completed vaccination, the most important condition for starting the With Corona, because of concerns for its side effects. In addition, although the economy may can be recovered by the With Corona, but the number of infected people may can be surged. In this paper, in order to awaken the people for the awareness of Corona 19 in advance of the With Corona, the Corona 19 is predicted through a non-linear probability process. Here, among the deep learning RNN, BI-LSTM, which is a bidirectional LSTM, and GRU, gates decreased than LSTM have been used. And this has been compared and analyzed through train set, test set, loss function, residual analysis, normal distribution, and autocorrelation, and compared and predicted for which has a better performance.

Diabetes patients are vulnerable to coronavirus disease 2019 (COVID-19) infection. Therefore, challenges arise concerning how to manage nutrition support to strengthen the immune system in diabetes patients. The purpose of this paper is to review the roles of macronutrients and specific micronutrients such as vitamin D, B12, folate, selenium, and zinc in supporting the immune system and examine the nutritional management method of diabetes patients during the COVID-19 pandemic. Evidence indicates that adequate amounts of protein, high omega-3 fatty acids, low refined sugars, high fiber content such as whole grains, and micronutrients including vitamin D, B12, folate, selenium, and zinc impact immune system function in diabetes patients. Consumption of a balanced diet with these nutrients is best to support the immune system in diabetes patients during the COVID-19 pandemic. [ABSTRACT FROM AUTHOR]

As the number of passengers using aircraft increases around the world, there may be more medical measures needed within the aircraft. These medical measures may also include measures against serious situations such as cardiopulmonary resuscitation (CPR). However, since the environment is different from the hospital in the aircraft, it may be difficult to cope with such a situation. Moreover, such in-flight CPR may become more difficult at a time when the proportion of out-ofhospital CPR is decreasing due to the recent COVID-19 pandemic. In this paper, I would like to summarize how in-flight CPR is performed and review the main discussions on CPR in the COVID-19 pandemic, and finally suggest how to perform a safe CPR in the COVID-19 situation.

Untact order payment has become a new normal since the COVID-19. BLE beacon is a technology that supports low-power wireless communication within 70 meters without Bluetooth pairing and is specialized for indoor positioning. Therefore, it is suitable for building and providing O2O services beyond B2C and B2B services. However, beacons have a lower utilization rate because they have fewer platforms than wifi that support long-distance wireless communication. Therefore, this paper aims to provide more convenient non-face-to-face related services than before by designing and proposing an O2O service platform using BLE beacons. When scanning beacons, not only does it receive advertising data that beacons have, but it also ensures that the actual distance between the user's terminal and beacons is accurately calculated. Through accurate location, the O2O service platform will be able to provide users with store information, such as coupons and discounts, museum exhibits, and traffic information at the right time.

Sudden implementation of online classes in higher education due to Covid19 pandemic implies a lot of worries about academic performance declining. Thus, this paper analyzed a class(CalculusI) taught 100% online which was the same as the offline class before. This class tried to maintain the same quality as the offline one by utilizing various teaching strategies. The result shows the academic achievement level was similar or higher than that of offline class, and so was the students’ perception and satisfaction degree. However, this was not just the outcome of online class, but it came from the professor’s well-designed teaching plan and smooth operation of the class. It implicates successful teaching methodology is more important factor than such medium difference as online or offline. This study suggests the potential of online classes after the Covid19 pandemic, and expects further studies verify the result in a lot more curricula. [ABSTRACT FROM AUTHOR]

Since the coronavirus disease 2019 (COVID-19) outbreak caused by the severe acute respiratory syndrome-coronavirus-2 virus (SARS-CoV-2), various complications have been reported. Although most COVID-19 cases exhibited flu-like symptoms, COVID-19 may dysregulate the immune response and promote overwhelming levels of inflammation in some patients. Inflammatory bowel disease (IBD) is caused by dysregulated or inappropriate immune responses to environmental factors in a genetically susceptible host, and a SARS-CoV-2 infection may act as a possible cause of IBD. This paper describes two pediatric patients who developed Crohn’s disease following a SARS-CoV-2 infection. They were previously healthy before the SARS-CoV-2 infection. On the other hand, they started to develop fever and gastrointestinal symptoms several weeks after recovery from the infection. They were diagnosed with Crohn’s disease by imaging and endoscopic studies, and their symptoms improved after treatment with steroids and azathioprine. This paper suggests that a SARS-CoV-2 infection may trigger IBD in predisposed patients.

In Vol. 31, No. 3, our journal prepared three review articles, an original paper, and two case reports. First, as COVID-19 continues for a long time, aviation workers, including pilots, are also experiencing mental problems such as depression. Therefore, we have compiled the basic principles for improving the mental health of pilots. Next, it is difficult to properly perform cardio-pulmonary resuscitation (CPR) when a cardiac arrest situation occurs in an aircraft. Moreover, in the context of the COVID-19 pandemic, CPR is more difficult because medical staff and other passengers may also be exposed to infections. Therefore, we have summarized the principles of CPR on board and ways to perform CPR while keeping the safety of medical staff and other passengers in the COVID-19 situation. The sudden change of gravity caused by space travel has various effects on the human body, and among them, the effect on the immune system is profound. Therefore, we reviewed the research methods to study the effect of gravity on the immune system and the results. In addition, we analyzed the demographic characteristics and health status of immigrant visa applicants who intended to immigrate to the United States over the past five years. Next, through two case reports, we reported cases of determining physical fitness for aviation service in patients who recovered after receiving appropriate treatment for chronic myeloid leukemia or renal cell carcinoma.

The present paper investigates poetry written in China on the theme of the COVID-19 pandemic following the outbreak in January 2020, considered both as a social phenomenon and as literary texts. The analysis is primarily interested in considering the impact of the pandemic on poetry’s interaction with social reality. In order to do so, the essay follows two trajectories. Firstly, it explores the public role performed by poets in the nationwide popular mobilization that sustained the party-state’s effort to curb the epidemic, with a strong emphasis on poetry as a social practice, specifically in a time of crisis, as outlined by both the state and the authors themselves. Secondly, a close reading of selected texts shows the heterogeneity of standpoints adopted by poets in their individual understandings of their role during China’s anti-COVID mobilization effort, especially in relation with the “master narrative” advanced by the state. The paper demonstrates that the final configuration of China’s pandemic poetry was made possible by Chinese poetry’s longstanding tradition of social responsibility, and that the transgression of boundaries between the official and unofficial poetry scenes, and “amateur” and “professional” authors, was instrumental to promote poets’ public engagement.

The COVID-19 pandemic has opened our eyes to numerous global problems that can only be solved on a global scale. Especially in light of the good performance of the Sinic region in containing and eliminating the coronavirus, the importance of intercultural dialogue between East and West became even more evident. In this context, this paper explores the role of digital technologies and the underlying ontology of digital objects in China as well as in the wider Sinic region. Indeed, the third millennium, which has just begun and will witness the accelerating trends of global warming and most likely the deepening of the gap between rich and poor, numerous wars, and new pandemics, will certainly be marked by the development of digital technologies. Therefore, the paper investigates the specific features of traditional Sinic perceptions of technology as such, as well as their ideational underpinnings, which certainly influence specific Sinic perceptions of digital objects. This will, I hope, provide us with a better understanding of the cultural conditionality of differences and commonalities in the global processes of digitalization and their ontological underpinnings, so that we can pay more attention to both the dangers and the opportunities that cross-cultural interactions in this area can offer us.

Artists are responding very differently to the COVID-19 around the world. In Japan, this has been manifested in artistic production of the mythical creature called Amabie, one of the yōkai. Most often, it appears as a mermaid, with both animal and human features recognizable by its three limbs, long hair, beak-like mouth and body covered by scales. This is a mythical character which, according to legend, allegedly predicted the plague and advised people to share drawings of its image with each other, thus protecting them from diseases. The character was documented for the first time in 1846 in one of the early kawaraban newspapers. This paper presents a new wave of Amabie that overran social media when COVID-19 seriously affected Japan. The author focuses on the world of art, where the character distinctly stepped to the fore, and examines the characteristics of Amabie’s interpretation by selected artists. One of the first to attract special attention in this respect is the artist Shigeru Mizuki (1922–2015), a master of the yōkai genre, whose comic book featuring Amabie was revived in the midst of the pandemic. He was followed by other illustrators, designers and artists or groups of artists. Utilization of the character of Amabie as a talisman, however, is specific not only of the artists’ domain. The mass popularization of the character, including drawings, puppets, paper sculptures, costumes, sweets, tattoos and the like can be followed through all kinds of social media. The paper attempts to lay stress on the phenomenon of the struggle of Japanese society with COVID-19 through the prism of popularizing Amabie folklore, which has become in the last few months an internet meme and mascot of pop culture that has spread around the entire world.

This paper investigates the relation between different models of ethics and their impact upon crises solution strategies. Because COVID-19 is a global-scale crisis, it has to be solved on the global level. In this framework, it is important to consider knowledge and ethical theories from different cultures. The paper outlines some theoretical groundworks for alternative models of social ethics from the perspective of traditional Chinese, particularly Confucian, philosophies. Among other issues, this perspective is meaningful because in the Sinitic areas the pandemic has so far been brought under control much quicker and more effectively than in other regions of the world. First, the paper introduces the Chinese philosophy of life and highlights its current relevance; then, it presents traditional Chinese models of relational and anti-essentialist concepts of the self and investigates their impact to the Confucian models of social ethics. On this basis, it illuminates some new ways of understanding interpersonal and intercultural interactions that might help us develop new strategies against current and future pandemics.

OBJECTIVES This study aims to summarize previous studies on the relationship between regular physical activity and the immune system in the elderly, and discuss optimal exercise modes to maintain immunity in preparation for novel infectious diseases that may continue to appear. METHODS This study referred to the academic papers based on the electronic database, and they were searched using the following keywords: physical activity, immunity, elderly, and COVID-19. RESULTS The elderly are more vulnerable to infectious disease such as the novel coronavirus disease 2019 (COVID-19) than other age groups because of lower physiological function and immune surveillance, consequently leading to higher severity of and mortality. Many studies on physical activity and immunity have confirmed that regular physical activity enhances immunity in the elderly population. Physical activity can delay immunosenescence and increase immune resilience by maintaining the function of the innate and acquired immune systems. Because the elderly have low physical fitness, physiological function, and immunity, exercise prescription for the elderly must be approached very carefully and in detail, considering various exercise modes such as exercise intensity and amount. As confirmed in previous studies, homebased light physical activity is a convenient, safe, and effective strategy for the health of the elderly. CONCLUSIONS In this study, balance training using body-weight is a good method of home-based physical activity for the elderly, because it not only improves immunity by increasing physical fitness but also prevents frequent falls by increasing the balance ability of the lower extremities. Future studies should be conducted on various exercise modes and optimal exercise training to improve immunity in the elderly.

Background and Objectives Cancer organizations worldwide have recently released care guidelines for cancer patients with coronavirus disease 2019 (COVID-19). Several studies have reported higher mortality rates in cancer patients with COVID-19. However, drawing robust conclusions remains challenging due to a lack of research on clinical prognostic factors in this patient group. Methods A comprehensive literature search was conducted using the PubMed, Embase, and Cochrane databases. We searched the keywords in the following combination: (“COVID-19” or “coronavirus” or “wuhan virus”) and (“cancer”). The search was performed on August 1, 2020, and only papers written in English were included in this study. We collected data from 3,215 cancer patients with COVID-19 from 16 studies and analyzed overall mortality after COVID-19 infection in cancer patients compared to controls, as well as prognostic factors for severity and mortality after COVID-19 infection. The prognostic factors analyzed encompassed demographics, comorbidities, symptoms, cancer treatment within 4 weeks of COVID-19 diagnosis, and treatment for COVID-19 infection. Results This meta-analysis evaluated mortality rates and related prognostic factors in cancer patients infected with COVID-19. First, 15 of the 16 studies reported mortality data; 663 patients died among a total of 3,215 people, resulting in a combined mortality rate of 21%. Second, the following poor prognostic factors were identified: male sex, older age (≥65 years), respiratory symptoms (e.g., cough and dyspnea), and other comorbidities (e.g., cardiovascular disease, hypertension, and chronic obstructive pulmonary disease). Conclusion The mortality of cancer patients infected with COVID-19 can reach about 20%.

Purpose: This study aimed to examine the differences in COVID-19 work-related characteristics, workload, anxiety, stress, and burnout between nurses working in the COVID-19 designated units and those in the general units caring for both COVID-19 and non-COVID-19 patients and to identify factors related to burnout in these two nurse groups. Methods: The study was conducted using data from 192 nurses in the COVID-19 designated units and 340 nurses in the general units from two general hospitals. The data were collected using self-report, structured questionnaires. Independent t-test, chi-squared test, and logistic regression analysis were performed. Results: There were no significant differences observed in workload and burnout between the two groups. For nurses in the general units, workload, stress, adequacy of the number of patients assigned, and the experience of temporary, floating staff were significant factors associated with burnout, while only clinical experience in the current unit was a significant factor among those in the COVID-19 units. Conclusion: Findings indicate significant differences in factors related to burnout between the two nurse groups. Thus, substantial support and strategies tailored to the working environments of each nursing unit are required to prevent burnout among nurses caring for COVID-19 patients. [ABSTRACT FROM AUTHOR]

Acute epiploic appendagitis is an uncommon cause of abdominal pain resulting from appendageal ischemia caused by torsion or thrombosis of the draining vein. It is frequently misdiagnosed as acute appendicitis or diverticulitis. The coronavirus disease 2019 (COVID-19) pandemic has changed how this rare disease is diagnosed. There was a report of a young men diagnosed with COVID-19 and epiploic appendagitis as a rare cause of abdominal pain. In addition, a 50-year-old men was diagnosed with epiploic appendagitis during the treatment of COVID-19. This paper reports the case of a 53-year-old men who presented with right lower quadrant abdominal pain after COVID-19 and was diagnosed with acute epiploic appendagitis by computed tomography image findings. The thrombotic condition of COVID-19 may contribute to acute appendagitis, but more studies are needed to confirm this hypothesis.

Purpose: This study aimed to confirm the mediating effect of social responsibility on the relationship between nurses' stress and burnout from Coronavirus disease (COVID-19) in tertiary general hospitals. Methods: For this descriptive cross-sectional study, online survey data from 193 nurses in three tertiary general hospitals were analyzed. Data were collected from March 30 to April 4, 2021. The following statistical analysis were conducted: t-test, ANOVA, Scheffé test, Pearson's correlation coefficient analysis, and Hayes Process Macro Model 4 (to test the mediating effect). Results: COVID-19 stress was positively associated with burnout (r=.28, p<.001) and social responsibility (r=.22, p=.002). Social responsibility was negatively associated with burnout (r=-.31, p<.001). Furthermore, the mediation analysis indicated that social responsibility mediated the relationship between COVID-19 stress and burnout. Conclusion: According to the results, the impact of COVID-19 stress on the burnout was mediated by social responsibility. Therefore, to prevent the burnout from COVID-19 of nurses, developing educational programs to enhance social responsibility are recommended. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this study was to analyze the trends and characteristics of infection-related patient safety incident reporting before and during the coronavirus disease 2019 (COVID-19) pandemic in Korea, and to provide basic data for preventing infection-related patient safety incidents and improving their management. Methods: A cross-sectional analysis of secondary national data (Patient Safety Reporting Data) was conducted. In total, 517 infection-related patient safety incidents reported from 2018 to 2021 were analyzed. Changes in the number of reports before and during the COVID-19 pandemic and differences in variables related to infection-related patient safety incidents were analyzed using the chi-square test and independent t-test in SPSS 29.0. Results: This study found that infection-related patient safety incidents decreased during the COVID-19 pandemic compared to before the pandemic. Furthermore, incident-related characteristics, such as the type of healthcare organization, severity of harm, and post-incident actions, changed during the COVID-19 pandemic. Conclusion: The many changes in the infection control system and practices during the COVID-19 pandemic may have contributed to a decrease in the reporting of infection-related patient safety incidents. It is hoped that longitudinal studies on patient safety incidents related to the pandemic and analytical studies on factors influencing patient safety incidents will continue to be conducted to prevent and improve patient safety incidents.

This paper studies how COVID-19 has affected the labor market in Korea through a general equilibrium model with multiple industries and occupations. In the model, workers are allocated to one of many occupations in an industry, and industrial or occupational shocks alter the employment structure. I calibrate the model with Korean data and identify industrial and occupational shocks, referred to here as COVID-19 shocks, behind the employment dynamics in 2020 and 2021. I find that COVID-19 shocks are more severe for those with jobs with a higher risk of infection and in those that are more difficult to do from home. Interestingly, the relationship between COVID-19 shocks and infection risk weakened as the pandemic progressed, whereas the relationship between COVID-19 shocks and easiness of work-from-home strengthened. I interpret the results as meaning that the pandemic may direct future technological changes to replace tasks that require contact-intensive steps, and I simulate the impact of such technological changes through the lens of the model. The results show that such technological changes will lower the demand for manual workers compared to the demands for other occupations. This contrasts with the earlier trend of job polarization, where manual workers continued to increase their employment share, with the share of routine workers secularly declining at the same time.

Since its emergence in Wuhan, China, COVID-19 has spread and had a profound effect on the lives and health of people around the globe. Most people who develop COVID-19 fully recover, but current evidence suggests approximately 10% to 20% of people experience a variety of mid- and long-term effects after they recover from their initial illness. These mid- and long-term effects are collectively known as post covid-19 condition or "long COVID". Studies have shown that a significant number of patients complain of multiple symptoms over a period of several months or longer. The symptoms of long covid include fatigue or muscle weakness, dyspnea, cognitive impairment, and depression or anxiety. These chronic symptoms can also negatively affect aviation safety. Therefore, this review summarizes studies of the long-term effects of COVID-19, and aeromedical implications of long COVID. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this study is to understand the actual status of fundamentals of nursing practice (FNP) education at nursing colleges, and the difficulties of FNP operation in the early stages of the COVID-19. Methods: This study used a descriptive design. Data collection was conducted from December 9, 2020 to January 31, 2021 using the self-report questionnaire method for a total of 95 nursing colleges. The questionnaire consisted of characteristics related to FNP, changes in FNP education, difficulties in operating FNP, and countermeasures in the COVID-19 situation. Results: Changes in FNP due to COVID-19 were distribution of practice places, reduction of the number of students, short-term intensive classes, and reduction of face-to-face practice. Most colleges conducted FNP face-to-face, but some schools showed that FNP was conducted non-face-to-face. The difficulties of operating FNP that instructors experienced induced concerns about a decrease in student competency due to lack of face-to-face practice and an unofficial increase in the number of teaching hours and physical demands on instructors due to the expansion of the division. Conclusion: In order to develop the capabilities of nursing students in other pandemic situations in the future, it is necessary to find systematic coping strategy to reduce the burden of FNP instructors, and to develop non-face-to-face online practice contents and consumables for online practice.

The news articles collected with keyword “non faceto-face” were analyzed through topic modeling applied with LDA algorithm. In this study, collected articles were divided into two periods, period 1(the beginning of COVID-19 spread) and period 2(the end of COVID-19 spread), according to issued date of the articles. The articles of period 1 showed support for non-faceto-face treatment, smart library, the beginning of the online financial era, non-face-to-face entrance exam and employment, stock investment for main topic words. And the articles of period 2 showed conversion to non face-to-face classes, increasing unmanned stores, online finance, education industry, home treatment for main topic words. Also, further issues were discussed through visualization of topic words. These results provide evidence that education and unmanned business in non-face-to-face industries are growing.

This study aims to understand the COVID-19 leftover vaccine reservation system from a Nudge viewpoint, examine its ethical justification, and propose a better policy to overcome the policy’s shortcomings. To defeat COVID-19, it is essential to build herd immunity through quick vaccine development and broad inoculation. The leftover vaccine reservation system has been considered to have contributed positively to raising the immunization rate among various governmental policies. In addition to its ethical rationale for preserving the autonomy of people who desire to get vaccinated, the leftover vaccine reservation system can be recognized for its efficacy in terms of regulations for effective vaccine distribution. However, this method has drawbacks that should be addressed, such as the requirement for real-time vaccine inventory checks and first-come, first-served scheduling. Therefore this study suggests ‘leftover vaccination automated reservation service’ as a particular policy that can supplement the constraints and function in more ethical and effective ways.

Coronavirus disease-19 (COVID-19) is caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV- 2) and has resulted in increased mortality worldwide. Several studies have identified the involvement of the gastrointestinal tract, respiratory tract, and other tissues. Although it has been reported that the angiotensin-converting enzyme-2 receptor affected by SARS-CoV is expressed more in the pancreas than in the lungs, the issue regarding the occurrence of pancreatitis is controversial. SARS Cov-2 rarely causes acute necrotizing pancreatitis without significantly affecting the respiratory and other systems. This paper presents a patient who underwent laparotomy due to acute necrotizing pancreatitis and hemodynamic instability caused by COVID-19 without any known risk factors.

As the number of passengers using aircraft increases around the world, there may be more medical measures needed within the aircraft. These medical measures may also include measures against serious situations such as cardiopulmonary resuscitation (CPR). However, since the environment is different from the hospital in the aircraft, it may be difficult to cope with such a situation. Moreover, such in-flight CPR may become more difficult at a time when the proportion of out-ofhospital CPR is decreasing due to the recent COVID-19 pandemic. In this paper, I would like to summarize how in-flight CPR is performed and review the main discussions on CPR in the COVID-19 pandemic, and finally suggest how to perform a safe CPR in the COVID-19 situation.

Objectives This paper summarizes effective waste management and disposal methods for plastic and medical wastes during the prolonged COVID-19 pandemic. Methods We reviewed the literatures reporting and identifying the current status and characteristics of wastes related to COVID-19, and the management and treatment guidelines for those wastes. We also investigated various technologies for waste treatment and disposal, and assessed the current status and future direction of the technologies in Korea. Results and Discussion In the first half of 2020 in Korea, the amount of plastic waste produced had increased by 15.6% year-on-year, and medical waste production also increased significantly from 0.6 ton in January 2020 to 2,928 ton in August 2021. All of the infectious wastes are currently being incinerated in Korea, but there are concerns on air pollutant emissions and insufficient treatment facilities. Municipal solid waste also suffers from a lack of landfill capacity and low price competitiveness in the recycling industry. Conclusions Policy and system need to be improved to reduce the infectious waste generation from the sources, and treatment and disposal technologies for produced wastes also need to be developed. Furthermore, hospitals and health care facilities should establish their own waste reducing systems which may include chemical treatment and sterilization units.

Purpose: This study was to identify how a nursing management practicum was operated during the COVID-19 pandemic in Korea. Methods: This study surveyed instructors teaching the nursing management practicum with a questionnaire covering five domains and 42 items. The data were analyzed using descriptive statistics and content analysis. Results: The practicum was performed mainly by mixed methods (40.8% and 38.5%), in hospitals only (30.8% and 60.4%), online only (19.8% and 1.1%) in 2020 and 2021, respectively. The mixed methods were most frequently used for instructor teaching and conferences (43.9% and 58.3%). and the average teaching time per week was 9.40 and 8.69 hours per week, respectively. Taking charge in one to three core nursing skill items, 87.8% and 90.1% of the respondents each year performed face to face evaluation for the skills. Four to six out of 12 POs were covered by 58.2% and 54.9% of the participants, respectively, in 2020 and 2021. The greatest difficulty under the pandemic was securing students' hospital assignments. Conclusion: The nursing management practicum needs to adopt various digital technologies, and create new education models including hybrid ones combining both contact and untact methods to improve the educational effect for the post COVID-19 era.

In the past two years, all sectors of society have been underdeveloped and suffered a significant damage due to COVID-19. In particular, people who were working in many areas of research were unable to do anything due to restrictions on meetings with people and social distancing. The purpose of this study is to develop a social distancing device that allows users to maintain the distance in accordance with the government guidelines through an analysis of people's social distancing methods in the COVID-19 society through UX Design. In order to develop the social distancing device, the distance is expressed by changing the color of LED based on research related to UI design such as ultrasonic distance sensor, battery, charging method, distance display method, etc. The outer form of the social distancing device is designed using 3D, the device is developed by installing ultrasonic distance sensor, neo-pixel module and Arduino after printing a prototype using a 3D printer, and this device is tested to develop a final product that helps the social distancing practice amid COVID-19.

In Vol. 31, No. 3, our journal prepared three review articles, an original paper, and two case reports. First, as COVID-19 continues for a long time, aviation workers, including pilots, are also experiencing mental problems such as depression. Therefore, we have compiled the basic principles for improving the mental health of pilots. Next, it is difficult to properly perform cardio-pulmonary resuscitation (CPR) when a cardiac arrest situation occurs in an aircraft. Moreover, in the context of the COVID-19 pandemic, CPR is more difficult because medical staff and other passengers may also be exposed to infections. Therefore, we have summarized the principles of CPR on board and ways to perform CPR while keeping the safety of medical staff and other passengers in the COVID-19 situation. The sudden change of gravity caused by space travel has various effects on the human body, and among them, the effect on the immune system is profound. Therefore, we reviewed the research methods to study the effect of gravity on the immune system and the results. In addition, we analyzed the demographic characteristics and health status of immigrant visa applicants who intended to immigrate to the United States over the past five years. Next, through two case reports, we reported cases of determining physical fitness for aviation service in patients who recovered after receiving appropriate treatment for chronic myeloid leukemia or renal cell carcinoma.

This study investigates the effect of COVID-19 on the dynamics of women’s employment. The data reveal that the employment situation of married women worsened more than that of married men after COVID-19 except during the fourth wave of pandemic. We also find that many married women have transitioned from employment to non-participation, in particular during the first and second waves of COVID-19. This transition pattern for married women is strong enough to offset the added worker effect during COVID-19. [ABSTRACT FROM AUTHOR]

The coronavirus pandemic has changed our lives dramatically and caused much fear around the world. While social media can contribute to faster information flow, this environment also gives rise to intensifying anxiety. This paper examines the research questions of how the Chinese National Commission (NHC), as the main authority for the health-related issues, presents the news about COVID-19 pandemic to English-speaking readers, which topics related to the coronavirus are stressed most, and what reporting strategies are used in presenting the current events and issues. The results indicate that the authorities are well-informed about the dynamics of public attention, since the same dynamics can be observed in the amount and structure of news. Moreover, from the perspective of reporting strategies we can see that the authorities subtly follow all the criteria that were proposed to allay fears and slow down or break the spiral of negativism with regard to the pandemic.

The article examines the specifics of the Chinese containment measures of the COVID-19 pandemic and their social consequences at the beginning of 2021. The author analyses empirical psychological research results on distress and anxiety of people in times of the first wave of the COVID-19 pandemic in China, and explores to what degree the individual feelings of anxiety in contemporary China are conditioned by the traditionally prevailing absence of faith in higher transcendent forces on the one hand, and social isolation on the other. It proceeds from Xu Fuguan’s interpretation of the origins of a traditional Chinese concept of “concerned consciousness” (youhuan yishi 憂患意識). The author shows that this concept can be compared to the feeling of anxiety, but highlights important differences which separate it from the anxiety as developed and understood in the framework of modern Western philosophy. The paper aims to provide some preliminary answers to the questions of whether and in what way such a traditional feeling of anxiety in the sense of a “concerned consciousness” manifested itself in the period of social isolation that was implemented as a part of the government measures for the COVID-19 pandemic in China. These questions are being investigated through an analysis of philosophical studies on concerned consciousness on the on hand, and a contemporary case study on the other. The results show that the specifically Chinese kind of anxiety, which is rooted in concerned consciousness, is tightly linked to the relational nature of Chinese ethics and the corresponding understanding of individual identity. In addition, it is connected with the traditional understanding of human destiny, which is not fatalistic or determinist, but rather based on autonomous decisions based on the social responsibilities of a free human self.

This study extracts topics related to university education through newspaper articles and analyzes the characteristics of each topic and the reporting patterns of each newspaper. The 9 topics were discovered using LDA. Topic 1 and Topic 3 are related to university support projects for education, but Topic 3 is focused on local universities. Topic 2 is about university education after COVID-19, Topic 4 teaching-learning methods, Topic 5 government policies, Topic 6 the high school education contribution university support projects, Topic 7 the university education vision, Topic 8 internationalization, and Topic 9 the entrance exam. The Chosun Ilbo, Kyunghyang, and Hankyoreh reported a lot of articles associated to lectures after COVID-19, government policies, and comments on university education. Relevant articles since 2016 have been analyzed by newspaper type and before/after COVID-19 through which differences in the topics were studied and discussed. These findings would suggest a basic policy guideline for university education and imply that the positive and negative effects of the media need to be considered. [ABSTRACT FROM AUTHOR]

This study investigates the underlying mechanism of YOLO in millennial consumer, especially the influence of perceived economic recession on the present-biased preference. In addition, it was attempted to expand the implicit theory by proposing the individual’s entity belief as a mediator for the effect of perceived economic situation on consumers’ present-biased seeking behavior. In three experimental studies, undergraduate students who both highly primed and measured negative economic situation showed more favorable attitudes towards present-biased persuasive message and related products. The results of this research provides practical implication for marketers especially in the current situation experiencing economic slowdown due to low economic growth and COVID 19.

Prolonged social distancing due to coronavirus disease 2019 (COVID-19) has brought about changes in people’s lives, including changes in physical activity, eating habits, and an increase in people’s feelings of depression. These changes can be negative effects on diabetes management. Meal planning is one of the most effective things diabetic patients can do to control blood sugar. Active nutrition management is recommended using various diabetes management applications. Methods and studies on dietary guidelines and non-face-to-face nutritional management are needed in consideration of the continued spread of COVID-19 infections. [ABSTRACT FROM AUTHOR]
