Objectives: The lack of advance planning in a public health emergency can lead to wasted resources and inadvertent loss of lives. This study is aimed at forecasting the needs for healthcare resources following the expansion of the coronavirus disease 2019 (COVID-19) outbreak in the Republic of Kazakhstan, focusing on hospital beds, equipment, and the professional workforce in light of the developing epidemiological situation and the data on resources currently available. Methods: We constructed a forecast model of the epidemiological scenario via the classic susceptible-exposed-infected-removed (SEIR) approach. The World Health Organization's COVID-19 Essential Supplies Forecasting Tool was used to evaluate the healthcare resources needed for the next 12 weeks. Results: Over the forecast period, there will be 104 713.7 hospital admissions due to severe disease and 34 904.5 hospital admissions due to critical disease. This will require 47 247.7 beds for severe disease and 1929.9 beds for critical disease at the peak of the COVID-19 outbreak. There will also be high needs for all categories of healthcare workers and for both diagnostic and treatment equipment. Thus, Republic of Kazakhstan faces the need for a rapid increase in available healthcare resources and/or for finding ways to redistribute resources effectively. Conclusions: Republic of Kazakhstan will be able to reduce the rates of infections and deaths among its population by developing and following a consistent strategy targeting COVID-19 in a number of inter-related directions.

In this study, the objective of the study was to verify how college students' entourage and transformational leadership can affect employment and entrepreneurship perception. In addition, with the coronavirus infection, which has a widespread global impact over the past few months, we want to see how the social issue of pandemic affects the personal characteristics of college students and their perceptions of employment and entrepreneurship. Research Results University students with high entrepreneurship and transformational leadership perceived the social issue of the Corona 19 pandemic as a crisis, which is comparable to the economic crisis, and rather than cringe, adapting to the shift of a new paradigm, new job opportunities or opportunities for entrepreneurship It was found to be an opportunity to recognize as. As the untact society is expected to become a new normal, securing new employment and entrepreneurship opportunities is emerging as an important factor through cultivation of entrustment and transformational leadership. The results of this study are based on the need for practical education on entrepreneurship and transformational leadership, such as creating a business model to strengthen the ability to'explore opportunities' to explore opportunities in crisis for potential entrepreneurs and college students with potential employment potential. Is suggesting.
Trends in the developing era to discover and design peptide-based treatments throughout an epidemic infection scenario such as COVID-19 could progress into a more efficient and low-cost therapeutic environment. However, the weakening of proteolysis is one downside of natural peptide drugs. But, peptidomimetics may help resolve this issue. In this review, peptide and peptide-based drug discovery were summarized to target one key entry mechanism of severe coronavirus pulmonary emboli syndrome (SARS-CoV-2), which encompasses the association of the host angiotensin-converting enzyme-2 (ACE2) receptor and viral spike (S) protein. Furthermore, the benefits of proteins, peptides and other possible actions that have been studied for COVID-19 through new peptide-based treatments are discussed in the review. Lastly, an overview of the peptide-based drug therapy environment is comprised of an evolutionary viewpoint, structural properties, operational thresholds, and an explanation of the therapeutic area.
Purpose: The objective of this study was to determine the effects of coronavirus disease 2019 (COVID-19) on the volume of trauma patients, the number of orthopedic trauma operations, and the severity of injuries. We also investigated the correlations between social distancing and these variables. Methods: This was a retrospective review of trauma patient cases at a single focused training center for trauma in Korea from January 2017 to April 2021. The COVID-19 group included patients treated from January 1 to April 30 in 2020 and 2021, and the control group included patients treated during the same months from 2017 to 2019. The volume of trauma patients according to the level of social distancing was evaluated among patients treated from August 2, 2020 to November 23, 2020. Results: The study included 3,032 patients who presented to the emergency department with traumatic injuries from January to April 2017 to 2021. The average number of patients was 646.7 and 546.0 in the control and COVID-19 groups, respectively. The percentage of patients injured in traffic accidents (TAs) decreased from 25.0% to 18.2% (P<0.0001). The proportions of in-car TAs and pedestrian TAs also decreased from 6.7% and 10.8% to 3.5% and 6.0%, respectively (P=0.0002 and P<0.0001). The percentage of bicycle TAs increased from 2.4% to 4.0% (P=0.0128). The proportion of patients with an Injury Severity Score above 15 and the mortality rate did not change significantly. As the level of social distancing increased, the number of trauma patients and the number of trauma injuries from TAs decreased. The number of orthopedic trauma operations also depended on the social distancing level. Conclusions: The number of trauma patients presenting to the emergency department decreased during the COVID-19 period. The volume of trauma patients and orthopedic trauma operations decreased as the social distance level increased.

Purpose: This study investigates the characteristics and prognosis of acute poisoning patients visiting nationwide emergency departments before and after the Coronavirus disease 2019 (COVID-19) pandemic. Data were obtained from the National Emergency Department Information System (NEDIS). Methods: This nationwide retrospective observational study included acute poisoning patients who visited the emergency departments between February 1 to December 31, 2020, which has been determined as the pandemic period. The same periods in 2018 and 2019 were designated as the control periods. The primary outcome assessed was the length of stay in emergency departments (EDLOS). The secondary outcomes examined were intensive care unit admission rate and in-hospital mortality rate before and after the pandemic. A subgroup analysis was performed for inpatients and intentional poisoning patients. Results: A total of 163,560 patients were included in the study. During the pandemic, the proportion of women increased from 50.0% in 2018 and 50.3% in 2019 to 52.5% in 2020. Patients aged 20-29 years increased from 13.4% in 2018 and 13.9% in 2019 to 16.6% in 2020. A rise in cases of intentional poisoning was also noted - from 33.9% in 2018 and 34.0% in 2019 to 38.4% in 2020. Evaluating the hospitalized poisoned patients revealed that the EDLOS increased from 3.8 hours in 2018 and 3.7 hours in 2019 to 4.2 hours in 2020. ICU admissions were also markedly increased (2018, 48.2%; 2019, 51.8%; 2020, 53.2%) among hospitalized patients. Conclusion: The COVID-19 pandemic has changed the epidemiology, clinical characteristics, and prognosis of acute poisoning patients visiting nationwide emergency departments in Korea. The proportion of young adults, women, and intentional poisoning patients has increased after the COVID-19 pandemic. Prolonged length of stay at the emergency department and an increased rate of intensive care unit admissions were determined in hospitalized acute poisoning patients.
Purposes: Evaluate the level of mental health of administrative workers in medical institutions during the COVID-19 epidemic, and check the relationship. Methodology: It targeted 183 administrative workers at medical institutions located in Jeollabuk-do. The data survey method used a self-filled questionnaire, and the data collection period was 30 days from November 16, 2021 to December 16, 2021. A comparative analysis was conducted to find out the correlation between the subjects' biological factors, environmental factors, lifestyle factors, job related factors and depression, Post Traumatic Stress Disorder, and job stress. Findings: As an influencing factor of depression, it was found that the longer the working period, the higher the depression, and the higher the position, job satisfaction, and the total amount of smoking, the lower the depression. Due to the effect on Post Traumatic Stress Disorder, the higher the total amount of smoking, the higher the Post Traumatic Stress Disorder after effects, and the higher the organizational commitment and job satisfaction, the lower the Post Traumatic Stress Disorder aftereffects. It was found that organizational commitment had the highest influence on Post Traumatic Stress Disorder. As an influencing factor on job stress, it was found that the higher the job related factors was job satisfaction and organizational commitment, the lower the job stress. Practical Implications: Variables such as moderate physical activity, alcohol consumption, total smoking, working period, position, job satisfaction, and organizational commitment were identified as factors influencing depression, Post Traumatic Stress Disorder, and job stress during the COVID-19 pandemic.
This study analyzed the differences in the general characteristics, mental and health-related factors, eating habits, and nutrient intake of Korean male youths before and after the outbreak of the coronavirus disease 2019 (COVID-19). The data of a total of 1,231 subjects, from among the participants in the 2018 and 2020 Korea National Health and Nutrition Examination Survey (KNHANES), were analyzed. The 2020 group had fewer married members than the 2018 group. The subjects in the 2020 group weighed more (P<0.05), had a higher waist circumference (P<0.01), and showed greater weight gain (P<0.05) than the 2018 group subjects. The aerobic physical activity of the 2020 group was lower (P<0.01) compared to the 2018 group. The members of the 2020 group had higher depression scores (P<0.01), suicidal tendencies (P<0.01), and need for counseling for mental problems (P<0.05) than those of the 2018 group. The prevalence of high fasting blood sugar levels and diabetes was higher in the 2020 group compared to the 2018 group. The frequency of breakfast (P<0.01) and dining out (P<0.001) and the proportion of breakfast (P<0.01) and dinner (P<0.05) taken with the family or non-family members was lower in the 2020 group than in the 2018 group. The rate of dietary supplement intake of the 2020 group was higher than that of the 2018 group (P<0.01). There were significant differences in the protein (P<0.05), riboflavin (P<0.01), and carbohydrate (P<0.01) intakes between the two groups. These results suggest that male youths had a higher waist circumference and high levels of depression, and showed a decrease in frequency of breakfast intake and dining out after the out break COVID-19 pandemic. Therefore, nutrition and health promotion programs are urgently needed to improve mental health, other health-related factors and nutritional status of male adults that are associated with the COVID-19 pandemic.

Objective: To develop a machine learning (ML) pipeline based on radiomics to predict Coronavirus Disease 2019 (COVID-19) severity and the future deterioration to critical illness using CT and clinical variables. Materials and Methods: Clinical data were collected from 981 patients from a multi-institutional international cohort with real-time polymerase chain reaction-confirmed COVID-19. Radiomics features were extracted from chest CT of the patients. The data of the cohort were randomly divided into training, validation, and test sets using a 7:1:2 ratio. A ML pipeline consisting of a model to predict severity and time-to-event model to predict progression to critical illness were trained on radiomics features and clinical variables. The receiver operating characteristic area under the curve (ROC-AUC), concordance index (C-index), and time-dependent ROC-AUC were calculated to determine model performance, which was compared with consensus CT severity scores obtained by visual interpretation by radiologists. Results: Among 981 patients with confirmed COVID-19, 274 patients developed critical illness. Radiomics features and clinical variables resulted in the best performance for the prediction of disease severity with a highest test ROC-AUC of 0.76 compared with 0.70 (0.76 vs. 0.70, p = 0.023) for visual CT severity score and clinical variables. The progression prediction model achieved a test C-index of 0.868 when it was based on the combination of CT radiomics and clinical variables compared with 0.767 when based on CT radiomics features alone (p < 0.001), 0.847 when based on clinical variables alone (p = 0.110), and 0.860 when based on the combination of visual CT severity scores and clinical variables (p = 0.549). Furthermore, the model based on the combination of CT radiomics and clinical variables achieved time-dependent ROC-AUCs of 0.897, 0.933, and 0.927 for the prediction of progression risks at 3, 5 and 7 days, respectively. Conclusion: CT radiomics features combined with clinical variables were predictive of COVID-19 severity and progression to critical illness with fairly high accuracy.

Purpose: This study investigated the characteristics and treatment outcomes of patients who visited the emergency department due to intoxication and analyzed the impact of the coronavirus disease 2019 (COVID-19) pandemic on their visits. Methods: A retrospective study was conducted using data from the National Emergency Department Information System (NEDIS) on patients who visited the emergency department due to intoxication between January 2014 and December 2020. In total, 277,791 patients were included in the study, and their demographic and clinical data were analyzed. A model was created from 2014 to 2019 and applied to 2020 (i.e., during the COVID-19 pandemic) to conduct a time series analysis distinguishing between unexpected accidents and suicide/self-harm among patients who visited the emergency department. Results: The most common reason for visiting the emergency department was unintentional accidents (48.5%), followed by self-harm/suicide attempts (43.8%). Unexpected accident patients and self-harm/suicide patients showed statistically significant differences in terms of sex, age group, hospitalization rate, and mortality rate. The time series analysis showed a decrease in patients with unexpected accidents during the COVID-19 pandemic, but no change in patients with suicide/self-harm. Conclusion: Depending on the intentionality of the intoxication, significant differences were found in the age group, the substance of intoxication, and the mortality rate. Therefore, future analyses of patients with intoxication should be stratified according to intentionality. In addition, the time series analysis of intentional self-harm/suicide did not show a decrease in 2010 in the number of patients, whereas a decrease was found for unintentional accidents.
Among calves' diseases, digestive diseases most frequently occur in Korea, and especially viral diarrhea is one of the most important diseases. This study was conducted to get some basic information for the control of the viral diarrhea in calves. The samples were obtained from 319 calves with clinical diarrhea from 195 farms in Gyeongnam south area (Gosung, Tongyung, Hadong) from June 2005 to August 2006, Viral detection was examined by polymerase chain reaction (PCR), Etiological viruses were detected from 171(53,6%) of 319 calves, and bovine rotavirus (BRV) were 130 (40,8%) and bovine viral diarrhea virus (BVDV) 41 (12,9%), and no coronavirus was confirmed, Statistical difference was found in BRV detection between summer (32.6%) and winter (57.7%). However there was no seasonal difference in BVDV. In detection rate of the calves under 19days, BRV was highest (55.1%), but BVDV lowest (5.1%). No big difference was in rate among herd size. However, BRV was lowest (26.8%) in the group over 51 heads, but BVDV was highest (19.5%) in the same.
