Background: This study aims to report how the practice of plastic surgeons and their attitude was during the first measure period of coronavirus disease 2019 (COVID-19) pandemic. Methods: A survey study was held among members of the Indonesian Association of Plastic Reconstructive and Aesthetic Surgeons during week 5 after the first report of COVID-19. A 10 multiple-choice questions (MCQs) and 1 essay covered key questions on the area of surgery and operating room, clinics, internal meeting, and consultation. The only open-ended question relates to the last MCQ addresses a future "flipped" medical practice. Results: Response rate was 45.6% among 228 members, with 89.4% did no practice or limited their service to emergency and urgent cases only. Only 1.9% kept their official meeting as usual, while the majority modified it. The practice in the operating theatre and clinic were also altered to comply with the measures; with 21.2% from the total respondents only allowed patients with exposure to come for visit after taking 14 days of self-quarantine. Teleconsultation was practiced by 50% of the respondents, while 41.3% agreed and 10.6% disagreed upon the future "flipped" medical practice. Conclusion: In general plastic surgeons have made supportive actions during the pandemic. Surgery was performed with all precautions at the utmost as a reflection of high alert of viral infection. Teleconsultation has been embraced via existing social media. Agreement upon the future "flipped" medical practice is reasonable. All in all, the actions were considered as most relevant.
This study was examined to identify effects of compliance with preventive behavior on COVID-19 of nursing college students. From April 24 to May 6, 2020, 195 nursing students in grades 1-4 responded to an online self-report questionnaire. Collected data were analyzed by descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients, and multiple regression using SPSS/WIN 23.0 program. The result showed that compliance with preventive behavior was positively correlated with knowledge and anxiety. The multiple regression revealed knowledge(β=.418, p<.001), anxiety(β=.280, p<.001), and experience of self quarantine(β=-.107, p<.05) to be significant compliance with preventive behavior. These variables accounted for 40.4% of compliance with preventive behavior. Conclusion Accurate and positive knowledge formation of COVID-19 of nursing students is necessary and the development and application of educational programs that can practice the performance of preventive actions in everyday life is necessary.
Purpose: The purpose of this study was to find stress mediation strategies for pandemic task forces in the future by identifying role stress experienced by local officials in public health centers working as COVID-19 response task force. Whether they suffered from trauma and post-traumatic stress disorder (PTSD) due to COVID-19 was also determined. Methods: Subjects for this research were 185 public health center workers in 7 northern Gyeonggi cities with at least three months of COVID-19 response task force experience. The investigation lasted for two months, from February to March of 2021. Data were collected using a self-administered questionnaire. Results: The average role stress of research subjects was 2.79±0.60. There were 64 subjects (34.6%) who answered 'yes' for trauma experience due to COVID-19. Subjects' role stress by sociodemographic and role characteristics displayed statistically significant differences in gender (t = -2.74, p= .007), age (F = 6.41, p= .002), profession (F = 0.01, p= .014), and COVID-19 response task (F= 3.01, p= .019). Specifically, role stress was higher for females than for males, those who were in their 20's (than 40's), a nursing profession (rather than others). Role stress was also higher in COVID-19 confirmed response work or in a self-quarantine work. There was a significant difference in trauma according to COVID-19 response roles (χ2 = 26.59, p= < .001) and other tasks given or not (χ2= 9.48, p= .002). Conclusion: It is necessary to take measures to reduce COVID-19 response task force's role stress and trauma.
The purpose of this study is to determine the issues of supplementation and improvement to prepare for the outbreak of new infectious diseases such as new variants of coronavirus disease 2019 (COVID-19) to guide work for a strategic new response to infectious disease. Public officials of Jeju Special Self-governing Province and health personnel responding to COVID-19, working at six public health centers in Jeju-do region were administered a survey about additional preparations to be made in the future, based on the period when COVID-19 was treated legally as a first-class infectious disease. Frequency analysis was conducted on the collected data. The Likert 5-point scale and Kruskal-Wallis test were used to compare the scores for effective response to emerging infectious diseases according to demographics. Among the important factors identified for effective response to new infectious diseases, 'facilitation of cooperation with public institutions' and 'facilitation of cooperation with private institutions' had the highest scores. In the future, when a patient presents with a new infectious disease, the step that needs to be supplemented in each phase of the public health center's response is 'immediate response team operation'. Further, public health centers responded that 'expansion of dedicated personnel related to infectious diseases' needs to be improved to respond to new infectious diseases. Along with the results of this study, considering the difficulties experienced by health personnel responding to new infectious diseases in preparation for future outbreaks of new infectious diseases, and to respond effectively, detailed and clear guidelines for responding to quarantine of patients of new infectious diseases will be needed.

Thinning of apple fruitlets is one of the most laborious and important works for the improvement of fruit quality and for the promotion of sufficient flower bud formation to prevent alternate bearing in commercial cultivars. Lateral fruits of self-thinning apple cultivars fall naturally within 30 days after full bloom and only central fruit remains to mature. Differences of gene expression between central fruit and lateral fruit were investigated by differential display (DD) PCR. Partial cDNAs of 30 clones from the central fruit and 24 clones from the lateral fruit were selected for nucleotide sequence determination and homology searches. The levels of transcripts coding for proteins involved in pathogenesis related proteins, senescence, temperature stress, protein degradation, fruit browning, sorbitol metabolism were significantly higher in pedicels of lateral fruit than in pedicels of central fruit. On the other hand, the up-regulation of proteins involved in anthocyanin and flavanol biosynthesis and ethylene synthesis were observed in pedicels of central fruit. In Real time PCR analysis, cytochrome P450 gene was confirmed as showing a higher expression level in lateral fruit than in central fruit. The results of this study indicate that differentially expressed genes are related to self-thinning characteristics in apple tree.
The purpose of the paper is to suggest government policies that are practically helpful to small business owners in pandemic situations such as COVID-19. To this end, keyword frequency analysis and word cloud analysis of text mining analysis were performed by crawling news articles centered on the keywords "COVID-19 Support for Small Businesses", "The Impact of Small Businesses by Response System to COVID-19 Infectious Diseases", and "COVID-19 Small Business Economic Policy", and major issues were identified through LDA topic modeling analysis. As a result of conducting LDA topic modeling, the support policy for small business owners formed a topic label with government cash and financial support, and the impact of small business owners according to the COVID-19 infectious disease response system formed a topic label with a government-led quarantine system and an individual-led quarantine system, and the COVID-19 economic policy formed a topic label with a policy for small business owners to acquire economic crisis and self-sustainability. Focusing on the organized topic label, it was intended to provide basic data for small business owners to understand the damage reduction policy for small business owners and the policy for enhancing market competitiveness in the future pandemic situation.

In this study, the bacteriological survey was examined on ice creams at manufacturing factories in Korea during the summer season of 2011. The nineteen selected among 166 samples by preliminary test were collected from 11 different manufacturing factories in four major manufacturers in May 2011. Samples from ice milk, ice creams, sherbets, and non milk fat ice creams were tested for the total aerobic bacteria, coliform bacteria, and five food borne pathogens, respectively. The results showed that the coliforms including E. coli O157:H7, Salmonella spp., Staphylococcus aureus, Clostridium perfringens, and Listeria monocytogenes were not detected on all the ice creams. The total aerobic bacteria of the packed samples examined ranged between $2.5{\times}10^3$ and $5.5{\times}10^5cfu/g$. One ice cream, two sherbets, and four ice milk samples exceeded the acceptable limits of total aerobic bacteria according to the Korean standards for ice cream ($1.0{\times}10^5cfu/g$) and others ($5.0{\times}10^4cfu/g$). The levels of these microorganisms from ice creams were higher in three original equipment manufacturers than seven self-manufacturers. Three of ten ice creams (30.0%), three of six ice milks (50.0%), and one of two sherbets (50%) exceeded the acceptable limits of total aerobic bacteria, respectively. The personnel hygiene procedures with chocolate and vanilla chip addition from the manufacturing process were the main sources of the microbial contamination of stick-bar type ice creams when being produced in a factory. Improvement of the hazard analysis critical control points (HACCP) system should be introduced into the ice cream factory to improve the microbial quality of the ice cream products in Korea.

Mesenchymal stem cells (MSCs) have been suggested as a primary candidate for cell therapy applications because they have self-renewal and differentiation capabilities. Although they can be expanded in ex vivo system, clinical application of these cells is still limited because they survive poorly and undergo senescence or apoptosis when transplanted and exposed to environmental factors such as oxidative stress. Thus, reducing oxidative stress is expected to improve the efficacy of MSC therapy. The milk protein lactoferrin is a multifunctional iron-binding glycoprotein that plays various roles, including reduction of oxidative stress. Thus, we explored the effect of lactoferrin on oxidative stress-induced senescence and apoptosis of human MSCs (hMSCs). Measurement of reactive oxygen species (ROS) revealed that lactoferrin inhibited the production of hydrogen peroxide-induced intracellular ROS, suggesting lactoferrin as a good candidate as an antioxidant in hMSCs. Pretreatment of lactoferrin suppressed hydrogen peroxide-induced senescence of hMSCs. In addition, lactoferrin reduced hydrogen peroxide-induced apoptosis via inhibition of caspase-3 and Akt activation. These results demonstrate that lactoferrin can be a promising factor to protect hMSCs from oxidative stress-induced senescence and apoptosis, thus increasing the efficacy of MSC therapy.
We analyze the HACCP Prerequisites of National Veterinary Research and Quarantine Service (NVRQS), Korea Food and Drug Administration(KFDA), and US Food Safety and Inspection Service (FSIS) and recommend contents and ranges to be complemented and used for the preparation of guidelines. We used the HACCP Notice of the Processing Livestock Act, the HACCP Application Manual for Livestock Processing Plants, the HACCP Notice of the Food Sanitation Act, US GPO 9 CFR and 21 CFR, US FSIS Directive 11,000.1, and HACCP-based Inspection reference guide of Consumer Services, North Carolina Department of Agriculture. The Prerequisites of NVRQS and KFDA are composed of 66 and 84 items respectively, without detailed guidelines for their application. This may decisively affect the application in the field and the evaluation activities. Water supplies, washing and disinfection monitoring tools, and examining and correcting plan are required to be improved. If the standards of compliance of each Prerequisite item as well as performance guidelines are given, the application and evaluation will be performed more effectively. The evaluation items should be associated with Prerequisite operations such as non-compliance complement, self-evaluation, and record keeping. Hazards found during official inspection should be promptly controlled not to contaminate the work places and processing items. As the HACCP is expected to spread from farms to tables, the standardized Prerequisite program among the official governments should be prepared.
