Companion animals are physically, mentally, and socially beneficial to humans, giving us great comfort in living in the Corona19 (COVID-19) era. It is also an era of the Fourth Industrial Revolution, featuring the convergence of information and communication technology. Korea, which is facing a super-aged society, has the highest suicide rate among OECD countries, and companion animals that are effective in emotional stability can be the answer. This study is about companion animals that are effective in stabilizing the emotions of the elderly, one of the major problems in the Republic of Korea, which is about to solve in a super-aged society with more than 20 percent of the elderly aged 65 or older, needs to solve. The impact of knowledge of raising companion animals on the satisfaction level of the elderly was investigated through the management and awareness of infectious diseases. Although the level of care of companion animals had a very significant (p<0.001) effect on the satisfaction of the companion animals, the recognition of infectious diseases has no statistical significance (p>0.05). Raising companion animals with knowledge of rearing increases the satisfaction level and can lead to a happier life. While personal learning is important, it is also believed that supporting education will be necessary as a policy consideration.

The purpose of this study was to examine whether the motivation for visiting experiential tourism can be maximized by revitalization of domestic tourism according to tourist image and visit satisfaction. In order to achieve this purpose, the four factors of educational motive, experiential motive, cultural motive, and communion motive of experiential tourists who visited domestic experiential tourist destinations, as well as the image of tourist destination, and suggestions for revitalizing domestic tourism through visit satisfaction were proposed. Therefore, the implications of this study are as follows. First, theoretical significance can be found by establishing the concept of domestic experience tourists' visit motives, image of tourist destinations and results related to visit satisfaction in the COVID-19 according to this study. It suggests that it is an essential condition for promoting a new change in which tourists participate in experiential tourism motives in the era of the pandemic by providing experiential tourism programs that are tailored to the level of tourists through research on the image of tourist destinations and their satisfaction with their visit motives. are giving Second, in terms of experiential tourism programs operated by domestic experiential tourism companies, it should be possible to promote the image of a safe tourist destination utilizing the characteristics of untact services that can provide non-face-to-face services. In addition, in an environment where visits to experiential tourism activities are somewhat limited in the era of the pandemic corona, it will help to revitalize domestic tourism and the local economy by expanding the non-face-to-face service to discover and develop direct experience programs in the region.

This study deals with keywords from social media on domestic portal sites related to COVID-19, which is spreading widely. The data were collected between January 20 and August 15, 2020, and were divided into three stages. The precursor period is before COVID-19 started spreading widely between January 20 and February 17, the serious period denotes the spread in Daegu between February 18 and April 20, and the stable period is the decrease in numbers of confirmed infections up to August 15. The top 50 words were extracted and clustered based on TF-IDF. As a result of the analysis, the precursor period keywords corresponded to congestion of the Situation. The frequent keywords in the serious period were Nation and Infection Route, along with instability surrounding the Treatment of COVID-19. The most common keywords in all periods were infection, mask, person, occurrence, confirmation, and information. People's emotions are becoming more positive as time goes by. Cafes and blogs share text containing writers' thoughts and subjectivity via the internet, so they are the main information-sharing spaces in the non-face-to-face era caused by COVID-19. However, since selectivity and randomness in information delivery exists, a critical view of the information produced on social media is necessary.

This study is a study on the regulatory focus and entrepreneurship that affect entrepreneurial motivation under uncertainty. In the empirical analysis results between the prevention focus, risk taking, and economic entrepreneurial motive, which were not observed in previous studies in Korea, this study tried to supplementally verify the previous studies by focusing on the limitations of the sample suggested as limitations. In particular, under a special external environment where uncertainty is deepening due to COVID-19 and the economic situation is being severely hit, we regressively analyze regulatory focus and risk taking, which are innate personal characteristics that can affect entrepreneurial motives. The mediating effect of risk taking was demonstrated. As a result of the empirical results, it was found that the prevention focus, risk taking, and economic entrepreneurial motivation had a significant effect, and it was shown that risk taking had a mediating effect between the prevention focus and the economic entrepreneurial motivation. This result is meaningful as a result not observed in previous studies, and it is judged that the control focus, which is an individual characteristic with a large innate tendency, interacts with the risk taking of the acquired tendency to influence the motivation to start a business. The results of this study can be of practical help by understanding and concentrating on regulatory focus and risk taking when conducting entrepreneurship or entrepreneurship education programs to entrepreneurs who dream of or want to start a business amid the growing uncertainty of the external environment. On the other hand, it is necessary to confirm whether these results, which are different from previous studies, are the effect of sample diversity or the external environment such as Corona 19, and re-verification through additional research is needed in the future.

This study was conducted to confirm the differences in nursing process competence, critical thinking disposition, and education satisfaction between clinical practicum and school practicum in the prolonged COVID19 pandemic. As an inequality control post-hoc design study, 55 students who agreed to participate in the study among the third year of nursing college students who took adult nursing practice were targeted. Data were collected by classifying the students who participated in the school practicum into the experimental group(N=29) and the students who participated in the clinical practicum into the control group(N=26). The collected data were analyzed using SPSS/WIN 22.0 program. As a result of the study, there was no significant difference in nursing process competence and critical thinking disposition between the two groups. However, in the control group, overall satisfaction with education (t=-9.82, p=.040) and recommendations to other students (t=-1.88, p<.001) were found to be significantly higher. Although it was not possible to confirm the difference between the effects of clinical practicum and school practicum as a result of the study, the significance of the study could be found in that there was no difference. In line with the post-corona era, future research on the development of a practicum program consisting of various contents, teaching methods, and practice to achieve the goal of practicum and analysis of the effectiveness of the program is suggested.

This study compared the influences of Korean psycho-social experiences on emotional-distress(stress, depression, anxiety, anger) of Koreans between two-periods during COVID-19. First, an online survey was conducted among 600 participants between April 13, 2020 and 21, while WHO had declared the pandemic, and Daegu-Gyungbuk were declared as a special-disaster area. Second, an online survey was conducted among 482 participants out of 600 study participants from the first study during August 21 to September 2, while COVID-19 re-spreaded around the world, and total confirmed cases were over 1,000 for a week in Seoul-Gyeonggi province. Hierarchical-regression analysis was used to determine the influence of personal characteristics, fear and social constraints, relationship conflict and income-decreasing factors on stress, depression, anxiety, anger in the two-time points. Results suggest that gender, quality-of-life, 'frequent information-checking about COVID-19', 'fear of unpredictability' and 'difficulties on hospital treatment access' predicted distress(stress, depression, anxiety, anger) at both Time1 and 2. 'Difficulties with official schedule' predicted distress at Time 1, and age, vulnerability to infection and difficulties with personal schedules predicted distress(stress, depression, anxiety, anger) at Time 2. Based on the reseults, implications and recommendations were presented.

Due to social and cultural changes and the growth of aging people living as a single because of aging, lonely deaths are steadily increasing, and each local government has begun to define them as a social problem. The legal basis began to be established. In order to explore policy measures to prevent lonely deaths, this study examined cases of lonely death prevention policies using smart digital information technology (AI, IOT), which is being promoted by Daegu Metropolitan City to promote non-face-to-face policies to prevent lonely deaths. Policies related to lonely deaths are divided into two axes: lonely death prevention projects and post-excavation support projects. In order to operate these businesses efficiently, the provision of non-face-to-face services through artificial intelligence and the Internet of Things is recognized as a new service delivery system, so the importance and necessity of non-face-to-face services is increasing. It is time that multifaceted changes and preparations are needed, such as establishing a system to expand the non-face-to-face industry at the national level. In order to respond to another national disaster situation in the future, the non-face-to-face smart care system is being expanded in various welfare policies such as preventing lonely deaths. It will have to be activated.

Objectives Although ginseng has been reported to protect neuronal cells and improve various cognitive functions, relationship between ginseng supplementation and response inhibition, one of the important cognitive domains has not been explored. In addition, effects of ginseng on in vivo human brain have not been investigated using the diffusion tensor imaging (DTI). The purpose of the current study is to investigate changes in intrusion errors and white matter microstructure after Korean Red Ginseng supplementation using standardized neuropsychological tests and DTI. Methods Fifty-one healthy participants were randomly allocated to the Korean Red Ginseng (n = 26) or placebo (n = 25) groups for 8 weeks. The California Verbal Learning Test was used to assess the number of intrusion errors. Intelligence quotient (IQ) was measured with the Korean Wechsler Adult Intelligence Scale. Depressive and anxiety symptoms were evaluated using Hamilton Depression Rating Scale, Hamilton Anxiety Rating Scale, and Hopkins Symptom Checklist-25. The fractional anisotropy (FA) was measured from the brain DTI data. Results After the 8-week intervention, Korean Red Ginseng supplementation significantly reduced intrusion errors after adjusting age, sex, IQ, and baseline score of the intrusion errors (p for interaction = 0.005). Change in FA values in the left anterior corona radiata was greater in the Korean Red Ginseng group compared to the placebo group (t = 4.29, p = 0.04). Conclusions Korean Red Ginseng supplementation may be efficacious for improving response inhibition and white matter microstructure integrity in the prefrontal cortex.

Many viruses including mouse hepatitis virus, corona, measles, and sidbis viruses are known as causative virus of inducing demyelination which means destruction of myelination in nervous system of mice. The purpose of this study is to investigate processing of myelination by co-culture of Schwann cells and neuronal cells and demyelination induced by infection of sindbis virusin rat. Schwann cells and neuronal cells from dorsal root ganglion (DRG) in embryos (E16) of rat were cultured in vitro respectively. The purified neuronal cells with anti-mitotic agents and purified Schwann cells were co-cultured. After that, infection of sindbis virus into this myelinated co-culture system was performed. Myelination and demyelination process were observed using antibody of myelin basic protein meaning presence of myelination.We identified myelination and demyelination processing using antibody of peripheral myelin protein 22 (PMP 22) meaning presence of myelinated neuron. This study was supported by the Basic Research Program through the National Research Foundation (NRF) funded by the Ministry of Science, ICT & Future Planning (NRF-2015R1C1A1A01053484 and 2017R1A2B3005753).

The purpose of this study was to determine if the addition of spermatozoa into the culture medium could influence the nuclear maturation of denuded porcine germinal vesicle (GV) oocytes in vitro. Cumulus-oocyte complexes were collected from follicles of 3 to 5 mm in diameter, The cumulus and corona cells were removed from oocytes. Porcine denuded oocytes were cultured in tissue culture medium containing spermatozoa. After 48 h culture, oocytes were examined for the evidence of GV breakdown, metaphase I, anaphase-telophase I, and metaphase II (M II). The proportion of oocytes reaching M II stage was significantly (P<0.01) increased in the oocytes cultured in media containing spermatozoa compared to those in media without spermatozoa $(31.9\pm1.8%\; vs\; 14.9\pm1.0%)$.No differences in the rates of M II were observed among the different period of spermatozoa exposure nor among the spermatozoa from different species. The proportion of oocytes reaching M II stage was significantly different between high and low concentrations of spermatozoa. The present study suggests that mammalian spermatozoa contain a substance(s) that improves nuclear maturation in vitro of GV oocytes. Enhancing effect of spermatozoa for oocytes maturation in vitro is a highly dose-dependent.
