ABSTRACT

The current study aimed to identify the rising phenomenon of online gambling in news data using Big Kinds, and to check the connection structure of important words.This study used the text-mining method to analyze text data collected from the Naver News portal to identify important patterns of Internet gambling. The web-crawling technique was adopted for data collection from January 1, 2020 to December 31, 2021. Since the coronavirus began to spread across Korea in 2020, a two-year time window was established. All news articles within this timeframe containing the keyword "internet gambling" were identified. A total of 1,494 articles were included.The text mining analysis showed that there have been many cases of arrests due to crimes, mainly online gambling, or crimes being committed after the perpetrator became debt-riddendue to online gambling. It can be seen that those who gamble online are mostly linked to crimes. Journalists have brought these topics up in their provocative articles, but the fact that there are no positive articles about online gambling shows that people should be careful about online gambling.Moreover, many articles state that the number of people who enjoyed online gambling has increased significantly as the time spent using the Internet at home increasedrapidly due to COVID-19 restrictions. Online gamblers are increasingly having a negative impact on society;however. the government has not formulated any clear measures against this issue. The online gambling industry is expanding, leading to a negative impact on society, and the government needs to take an urgent action.

ABSTRACT

Due to COVID-19, many educational institutions are using non-face-to-face online education services for programming lectures. However, it is not easy for one person to manage various features, which are scoring the assignment and practice, problem feedback, and so on, in the online programming education service. This paper develops an educational system for programming education using an open source-based online judge system for easy management of instructors. In addition, it defines and implements an academic interface. © 2022 IEEE.

ABSTRACT

The unavoidable transition to online education due to Covid-19 pandemic has impacted instruction at all grades and in all subject areas, including college level Mathematics courses. One of the issues that has been faced is the inability to proctor exams properly. Calculators with Computer Algebra Systems and their corresponding smart phone applications can provide not only answers to most problems, but they also provide solution steps. Mathematics departments at many institutions have established policies which regulated the use of calculators and smart phones in lectures and exams. However, lack of proper proctoring in online courses makes it possible for students to pass a course, even with a decent grade, without learning the concepts. On the other hand, as the use of computers became more common, many skills previously considered as required are not required anymore, such as learning how to use logarithmic tables to evaluate logarithms. In this study, we first demonstrate the capabilities of smart phone applications and provide tips for writing procedural problems that are not easily solvable by these apps. We show examples of problems that are solvable by the apps and suggestions to revise them. Second, we discuss general suggestions on how to revise the College Algebra instruction, especially for engineering students. Our suggestions aim to fill in the gaps that could potentially be created when these apps are commonly used among students. In summary, we review and revise College Algebra instruction and assessments to accept and incorporate the use of smart phone applications. Revised topics, together with effective assessment strategies will potentially improve learning outcomes, especially when the course is taught online. Our work concentrates on revision of College Algebra topics for Engineering students, but our strategy can be applied to revise other mathematics topics for any major. © American Society for Engineering Education, 2021

ABSTRACT

As COVID-19 vaccines have been distributed worldwide, the number of infection and death cases vary depending on the vaccination route. Therefore, computing optimal measures that will increase the vaccination effect are crucial. In this paper, we propose an Epidemic Vulnerability Index (EVI) that quantitatively evaluates the risk of COVID-19 based on clinical and social statistical feature analysis of the subject. Utilizing EVI, we investigate the optimal vaccine distribution route with a heuristic approach in order to maximize the vaccine distribution effect. Our main criterias of determining vaccination effect were set with mortality and infection rate, thus EVI was designed to effectively minimize those critical factors. We conduct vaccine distribution simulations with nine different scenarios among multiple Agent-Based Models that were constructed with real-world COVID-19 patients’ statistical data. Our result shows that vaccine distribution through EVI has an average of 5.0% lower in infection cases, 9.4% lower result in death cases, and 3.5% lower in death rates than other distribution methods. © 2021, Springer Nature Switzerland AG.

ABSTRACT

INTRODUCTION: Enterobacter species are important nosocomial pathogens. Enterobacter aerogenes is generally found in the human GI tract and does not cause disease in healthy people. We present a case of recurrent enterobacter bacteremia in a patient with hepatocellular carcinoma (HCC). CASE DESCRIPTION/METHODS: A 66 year old male with a history of hemochromatosis, HCC post chemoembolization, hepatitis C, portal vein thrombosis treated with Xarelto who presented with lower abdominal pain, vomiting, and poor oral intake for several weeks. His exam was significant for generalized abdominal tenderness. Vitals, cell counts were unremarkable and LFTs were mildly abnormal with ALP of 436 U/L. CRP was 203 mg/L. COVID-19 PCR negative. Blood cultures were 4/ 4 positive for Enterobacter aerogenes sensitive to ceftriaxone, cefepime, ertapenem and resistant to ampicillin/sulbactam and 1st and 2nd generation cephalosporins. He had been treated with ertapenem for 2 weeks for enterobacter bacteremia with unclear etiology, and the differential at this presentation included vascular infection such as thrombus or infective endocarditis. CT abdomen/ pelvis showed tumor thrombosis versus bland thrombus extending from the ablation field in into the inferior vena cava (IVC). Abdominal MRI confirmed 2.6 cm focus of signal intensity in right hepatic lobe contiguous with non occlusive IVC thrombus. TTE was negative for vegetations. Patient was discharged with 6 weeks of Ertapenem for suspicion of thrombophlebitis given the high grade recurrent bacteremia. DISCUSSION: To date there has been no major case reports or case series demonstrating a case of recurrent high grade enterobacter bacteremia with hepatocellular carcinoma. Spontaneous bacterial peritonitis caused by Enterobacter infections is more commonly associated with underlying HCC and upper gastrointestinal bleeding as compared to infection caused by E coli. For over the last two decades, there has been increasing suspicion about the induction of beta-lactam resistance in enterobacter infections mediated by chromosomally encoded amp-c beta lactamase following antibiotic exposure hence we opted to treat the patient with ertapenem for the 6 week duration. Our case demonstrates a patient with hepatocellular carcinoma with likely/presumed thrombophlebitis requiring prolonged antibiotic course.

ABSTRACT

INTRODUCTION: Although respiratory tract manifestations are most commonly reported symptoms in COVID-19, gastrointestinal system (esophagus, liver, gallbladder, pancreas and colon) is also affected by SARS-CoV-2, on the basis that they express angiotensin-converting enzyme 2 (ACE 2) receptor, the major receptor of SARS-CoV-2. We present a case of a patient with acute pancreatitis with COVID-19 infection that developed on day 6 of admission requiring a prolonged stay despite a normal respiratory status. CASE DESCRIPTION/METHODS: 68 year old male with a past medical history of hypertension, diabetes, CKD stage 3 who was a nursing home resident that tested positive for COVID-19 and was sent to ED for abnormal laboratory values. His admission labs were significant for Creatinine 6.6, BUN 77, CRP 158, Ferritin 920 and D-dimer 1.61. His creatinine improved to baseline with hydration. On day 6 of admission, he started complaining of nausea and vomiting. CT abdomen and pelvis and MRCP showed peripancreatic inflammatory changes consistent with acute pancreatitis. No biliary ductal dilatation or choledocholithiasis was seen. Lipase was 2035 along with an increase in WBC to 15.3 from 6.6. Abdominal exam was benign. His respiratory status was normal. He was managed with bowel rest and iv hydration. Gradually symptoms of nausea and vomiting improved. Diet was advanced gradually and the patient was discharged on day 19. DISCUSSION: The most common digestive symptoms reported in COVID-19 are lack of appetite, diarrhea, vomiting and abdominal pain. This was an example of a patient that had a delayed onset of GI symptoms including pancreatitis, while having normal respiratory function. Fluid hydration must be done judiciously in these patients, keeping in mind their respiratory status as it is suspected that these patients can be easily harmed by excessive fluid administration.
