In this paper, we propose a study on the purchasing intent of the new e-commerce consumer, the coronavirus may once again drive the structural change of China's economy, and the new online marketing model will be noticed during the epidemic. Through 438 questionnaires collected on the Internet, frequency analysis, element analysis, reliability analysis and structural equation analysis were performed using SPSS V22.0 and AMOS V22.0 methods. Study the validation of hypotheses in the model to reveal the reasons why consumers in the new e-business are exposed. The results show that e-commerce features of Internet celebrities and individual characteristics of Internet celebrities can only enhance consumers' satisfaction. Quasi social relationships only increase consumer satisfaction without generating the will to purchase directly. Consumer satisfaction is the core foundation that dominates long-term consumption. E-commerce should focus on the ability of online celebrities to sell their expertise and the adaptability of value and product characteristics when conducting online celebrity marketing.

From this book, $\ll$GeumGueyoryak Hakbyeongmaekjeungbyeongchi$\gg$, I finally got these conclusions of symptoms and pathology of Hakbyeong. 1. Hakbyeong has main symptoms of repetition of chillness and fever and its main pulse is pulse of Hyeon(弦) and position is in the middle of inside and outside. 2. Change in shape of pulse caused by Hakbyeong can have shape of pulse of Sak(數), Jee(遲), Kin(緊), Dae(大) and more kinds depending on patients constitution, the cause of disease, or whether he/she has been poisoned by other kinds. 3. After 15 days of symptoms, As Cheonki(天氣) and Inki(人氣) get stronger and Saki(邪氣) gets weaker, Jeongki(正氣) can be more recovered and the diseases can be disappeared. But if the disease dose not get away after another 15 days of showing symptom, that disease can be treated as cutting the Jingha under side of him/her. 4. The type of Hakbyeong which is diseased by the keeping the Haksa for long time, can be classified as Hagmo which has symptoms of chillness and fever outside, and of Jinggha inside, Danhag which has symptoms of difficulty with breathing, chest discomfort - caused by fever in the lung at ordinary times -, fever of extremities and nausea and that would make people worn out and thin after all, Onhag which has main symptoms of fever and Mohag which has symptoms of less fever and more chillness. 5. In this thesis it has been described, the Byulgabjunhwan(鼈甲煎丸), Baekhogagaejitang(白虎加桂枝湯), and Chokchilsan(蜀漆散) is the respective prescription for treatment of Hagmo, Onhag, and Mohag. From this conclusion, if the more research about the cause of disease, pathology and prescription of the each symptom from GeumGueyoryak hereafter, I could say more effective prophylaxis and treatment of epidemic disease like todays Hakbyeong can be found.

Objectives: Obesity is a growing epidemic with subsequent health consequences leading not only to reduced quality of life but also to increased medical costs. Recently nutritional balances are emphasized in the field of obesity, and especially maintaining proper equilibriums of minerals. The correlation of minerals obtained from the method of HTMA(Hair Tissue Mineral Analysis) with obese degree has not been studied in Korea yet. We studied any significant difference of mineral concentrations and components according to the obese degree. Methods: 78 subjects were analyzed who visited Garosero clinic of oriental medicine to lose their weight from June to November 2004. We used BMI(Body Mass Index), PBF(Percent Body Fat), WHR(Waist-Hip Ratio) and abdominal circumference obtained by bio-electrical impedance analysis as an obese degree. And we analyzed correlation with mineral concentrations and ratios obtained from HTMA. Results & Conclusion: 1. Na, K, Zn, Se had significant correlation with obese degree in case of nutritional minerals from HTMA. Especially, K had high significance. 2. Toxic minerals from HTMA had no significance with obese degree. 3. Rb had significant correlation with obese degree in case of additional minerals from HTMA. 4. Among important ratios from HTMA, Na/K had significant correlation with obese degree, but Ca/K had correlation except PBF, and Na/Mg had correlation except WHR. 5. Among toxic ratios from HTMA, Se/Hg had significant correlation with obese degree, but S/Hg had correlation except BMI. 6. Na, K, Zn, Rb, Na/K, Ca/K had significant differences between obesity groups classfied by BMI. Ob II group had sinificant difference from NW group in cases of K, Zn, Rb, Na/K, and Ob II group had sinificant difference from OW group in case of Ca/K.

This study noted the recent impact of Coronavirus Disease-19 (Corona 19) on the environment surrounding the library, and investigated the libraries' response activities. In addition, related issues on news media and social media were detected based on text mining techniques to engage environmental changes surrounding the library. Key issues were derived from 1,852 news reports on the library related to the Corona 19 situation and 227,983 tweets related to the library during the Corona 19 epidemic. Through this, implications were derived: prolonged 'Untact' situations, increased e-book lending, improved expectations for online services and librarians, and re-conceptualized library space. In addition, the direction of future services was discussed by selecting representative examples of library services provided in the non-face-to-face (untact) situation and dividing them into books, services, and spaces.

Purpose: The purpose of this prospective case-control study was to survey the detection rate of respiratory viruses in children with Kawasaki disease (KD) by using multiplex reverse transcriptase-polymerase chain reaction (RT-PCR), and to investigate the clinical implications of the prevalence of respiratory viruses during the acute phase of KD. Methods: RT-PCR assays were carried out to screen for the presence of respiratory syncytial virus A and B, adenovirus, rhinovirus, parainfluenza viruses 1 to 4, influenza virus A and B, metapneumovirus, bocavirus, coronavirus OC43/229E and NL63, and enterovirus in nasopharyngeal secretions of 55 KD patients and 78 control subjects. Results: Virus detection rates in KD patients and control subjects were 32.7% and 30.8%, respectively (P=0.811). However, there was no significant association between the presence of any of the 15 viruses and the incidence of KD. Comparisons between the 18 patients with positive RT-PCR results and the other 37 KD patients revealed no significant differences in terms of clinical findings (including the prevalence of incomplete presentation of the disease) and coronary artery diameter. Conclusion: A positive RT-PCR for currently epidemic respiratory viruses should not be used as an evidence against the diagnosis of KD. These viruses were not associated with the incomplete presentation of KD and coronary artery dilatation.

The purpose of this study was to investigate the protective effects against porcine epidemic diarrhea virus (PEDV) and transmissible gastroenteritis virus (TGEV) in suckling piglets by oral administration of IgY. Twenty piglets were divided into two groups with the same number: group I (treated with IgY) and group II (not treated). Group I was administerd orally with IgY for three days from one-day-old and experimentally challenged with PEDV and TGEV at four-day-old. The other was administered with saline solution and challenged with PEDV and TGEV at four-day-old. Serum antibody titers against PEDV and TGEV were examined by enzyme-linked immunosorbent assay (ELISA) and the detection of PEDV or TGEV antigen from feces and small intestines was performed by reverse transcription-polymerase chain reaction (RT-PCR) and indirect immunofluorescence (IFA). The antibody titers of the group I was higher than that of the other, and lasted at the end of experiment. In the detection tests of both virus from feces and small intestine, the rate of the group I was lower. Based on these results, oral administration of IgY may be effective to prevent the diarrhea caused by PEDV and TGEV.

The purpose of this study was to investigate the protective effects against porcine epidemic diarrhea virus (PEDV) and transmissible gastroenteritis virus (TGEV) in suckling piglets by oral administration of the IgY. The piglets were divided into two groups: test and control group. The former (n=10) were administered orally with IgY for three days from one-day-old and experimentally challenged with PEDV and TGEV at four-day-old. The latter (n=10) were administered with saline solution and challenged with same methods. Several tests were studied and summarized as follows; In clinical signs, the piglets of the control group showed the typical signs such as severe watery diarrhea, depression and anorexia but those of the test group recovered progressively. Control group showed 20% in mortality, but there were no death in the other. The gross lesions in the test were milder than those in the control, and there were typical findings as like congestion and distension of lumen in the control group. In histopathological study, the piglets of the control group had shortened and fused intestinal villi and a marked loss of epithelium, whereas the others showed milder changes. It could be concluded that oral administration of IgY, specific yolk-antibody against PEDV and TGEV is effective to prevent PEDV and TGEV infection in suckling piglets.

Purpose: This study aimed to evaluate nursing students' understanding of the prevention of COVID-19, as well as their anxiety towards the disease and their perception of their professional identity in the wake of the pandemic, in Zhengzhou, China. Methods: A cross-sectional study was designed to investigate 474 nursing students by cluster sampling using a stratified questionnaire from February 15 to March 31, 2020. Multiple linear regression was used to identify the factors affecting professional identity. Binary and multiple logistic regression were used to identify the factors affecting anxiety. Results: Responders with a high level of understanding of COVID-19 and frequent use of behavioral strategies for its prevention comprised 93.2% and 30.0% of the cohort, respectively. Professional identity was significantly associated with gender and anxiety (p < .050). The prevalence of anxiety among nursing students was 12.4%. Male (odds ratio [OR] = 2.39; 95% confidence interval [CI] = 1.26~4.52), sophomores (OR = 5.30; 95% CI = 1.61~7.45), and infrequent use of prevention measures (OR = 3.49; 95% CI = 1.16~5.19) had a significant effect on anxiety. Conclusion: Anxiety during the COVID-19 epidemic gives an adverse effect on the professional identity of nursing in students. Nursing education institutions need to provide psychological counseling services for nursing students, in addition to improving their teaching of COVID-19 prevention strategies.

Pathogenic microbial foodborne disease outbreaks (PMFBDOs) have increased in many countries, the boom in food service establishment is not matched by effective food safety and control. In this study, we investigated the current state and the epidemic aspects of FBDOs in Korea and Japan. In Korea, the average prevalence rate of foodborne disease (FBD) was 15.0 per 100,000 population and cases per outbreak of FBD was 57.0. During the same period in Japan, the prevalence rate showed an average of 24.9, and the cases per outbreak were 16. When both prevalence rate and cases per outbreak were compared, the prevalence rate in Japan was much higher than that in Korea (p<0.01). However, average cases per outbreak of FBD in Japan were much lower than those in Korea (p<0.01). In Korea, outbreaks of FBDs were more common in spring (p<0.01), while in Japan, more frequent in summer and winter (p<0.01). Outbreaks of FBD occurred largely through restaurant and school foods (32.0% and 27.5%) in Korea. In Japan, the proportion of the outbreak cases in the restaurant and home were 23.7% and 12.1%, and cases of unknown causes of FBDs were 48.2%, respectively. Bacteria were the major causes of infection in both countries. The prevalence of PMFBDOs by Salmonella spp. Vibrio parahemolyticus and Staphylococcus aureus were much higher in Korea, while those by Camphylobacter spp. and SRSV were more common in Japan. The causes by virus were more frequent in Japan (13.7%) than in Korea (7.7%). The prevalence of FBDs in Korea and Japan showed characteristic differences, especially in the PMFBDOs due to such factors as geography, climate, culture, diet and food management.
