This study investigated the relationship between knowledge of COVID-19, the risk of exposure to subjective infectious diseases, and the degree of infection control practices for dental personnel. For dental personnel currently working in dentistry, a survey consisting of 10 questions about COVID-19 knowledge and 63 questions about infection control practices was conducted. This study analyzed 126 survey data collected by distributing questionnaires form May 30 to June 20, 2020. Data was analyzed using t-test, ANOVA, and Pearson correlation. The average level of knowledge of COVID-19 was 5.44 out of 10, the average risk of exposure to infectious diseases was 3.86 out of 5, and the average level of infection control practices was 4.05 out of 5. The risk of exposure to infectious diseases was positively correlated with dental waste (r=.184). It was found that there was a significant positive correlation between infection control practices and sub-factors of infection control practices (p<0.001). To prevent the spread of COVID-19 and infectious diseases and to reduce the risk of exposure to infectious diseases for dental personnel, the practice of infection control should be improved. It is necessary to cultivate infection control experts and have mandatory infection control education and social regulations.

Background: The emergence of new infectious diseases threatens public health, increasing socioeconomic damage, and national risks. This study aimed to develop an evidence-based risk assessment tool to quickly respond to new infectious diseases. Methods: The risk elements were extracted by reviewing the risk assessment methods of the World Health Organization, United States, Europe, United Kingdom, and Germany, and the validity and priority of elements were determined through expert meetings and Delphi surveys. Then, the scale and level for each risk element were defined and a final score calculation method according to the risk evaluation result was derived. The developed risk assessment tool was verified using data at the time of domestic transmission of an emerging infectious disease. Results: In case of spread of actual infectious diseases, priority is determined based on the criticality of the elements in each area of transmissibility and severity, from which the weighted score of the risk assessment is derived. Then, the risk score for each element was calculated by multiplying the average value of the risk evaluation by its weight and the evaluation risk assessment score for the two areas was calculated. At last, the final score is plotted in a matrix where the x-axis indicates the transmissibility and the y-axis the severity and plotted on the coordinate plane for time series use. Conclusion: With respect to transmissibility and severity, this risk assessment method to respond to new and re-emerging infectious diseases enables rapid and evidence-based evaluation by quantitatively and qualitatively assessing various risk elements.

The development of transport is being easily shared with people all over the world. It is necessary to appropriately and effectively revise the domestic quarantine law because the fatal infectious diseases are at risk of being easily shared. Today, Korea has an advanced quarantine system approved by World Health Organization, but it maintains partnerships with related ministries (Ministry of Foreign Affairs, Ministry of Justice, local medical institutions) and to introduce new medical technology (electronic quarantine) is important. And since the prevention of quarantine infectious diseases and prevention of the spread, in order to maintain international cooperation with the International Health Regulations, the quarantine law and the system should be amended and improved effectively and it is also a way to prepare for the outbreak of new quarantine infectious diseases. In the past, Korea has experienced great confusion during the past outbreak of swine flu and Middle East respiratory syndrome coronavirus. To prevent similar cases from recurring in the past, the revision of the quarantine law and the improvement of the system should be done to cope with the changing environment (new infections, increased number of overseas travelers, etc.).

In human immunodeficiency virus (HIV)-infected patients, Pneumocystis jirovecii pneumonia (PCP) is a well-known opportunistic infection and its management has been established. However, PCP is an emerging threat to immunocompromised patients without HIV infection, such as those receiving novel immunosuppressive therapeutics for malignancy, organ transplantation, or connective tissue diseases. Clinical manifestations of PCP are quite different between patients with and without HIV infections. In patients without HIV infection, PCP rapidly progresses, is difficult to diagnose correctly, and causes severe respiratory failure with a poor prognosis. High-resolution computed tomography findings are different between PCP patients with HIV infection and those without. These differences in clinical and radiological features are due to severe or dysregulated inflammatory responses that are evoked by a relatively small number of Pneumocystis organisms in patients without HIV infection. In recent years, the usefulness of polymerase chain reaction and serum β-D-glucan assay for rapid and non-invasive diagnosis of PCP has been revealed. Although corticosteroid adjunctive to anti-Pneumocystis agents has been shown to be beneficial in some populations, the optimal dose and duration remain to be determined. Recent investigations revealed that Pneumocystis colonization is prevalent and that asymptomatic carriers are at risk for developing PCP and can serve as the reservoir for the spread of Pneumocystis by airborne transmission. These findings suggest the need for chemoprophylaxis in immunocompromised patients as well as infection control measures, although the indications remain controversial. Because a variety of novel immunosuppressive therapeutics have been emerging in medical practice, further innovations in the diagnosis and treatment of PCP are needed.

Smart livestock, which combines information and communication technology (ICT) with livestock, can be said to be an effective solution to existing livestock problems such as productivity improvement, odors, and diseases. So far, it has hardly been universalized; thus, it is necessary to develop automation devices to reduce labor by localizing automation devices to expand the distribution of ICT technology to farms, and to advance precise specifications and health management technology using biometric information. Weighing scales currently being used in livestock farms are to prevent the spread of diseases by diagnosis and preparation for AI and other diseases in advance, using information on the growing weight of duck breeding. However, accurate values cannot be obtained due to poor breeding conditions. In this paper, we developed a separate data transmission system kit for the weighing scale and placed the sensor on top of the weighing scale so that the sensor wire is not affected by pollutants or ducks on the floor. A display function was provided, and a method of receiving and analyzing the serial port data of the weighing device, and then transmitting them to the data collection server was implemented.

The clinical manifestation of pericardial disease is similar to that of coronary artery disease and aortic disease. Therefore, a timely and accurate diagnosis is necessary. The pericardium is a 2-layered membrane that envelops the heart and great vessels, and there are numerous anatomic variations and pathologic conditions. Large or unusually located pericardial recesses can be easily mistaken for abnormal findings. Additionally, primary pericardial diseases resulting from infections, tumors, and injuries are possible; further, diseases can quickly spread along the pericardium. Echocardiography is generally the first imaging tool used to evaluate the pericardium. However, it has limited windows and poor resolution. Besides, the evaluation of postoperative echocardiography is sometimes limited. Currently, CT and MR imaging are useful for evaluating pericardial diseases. Detailed knowledge of the pericardium is important for interpreting the images and clinical results.

Background: Intraperitoneal spread of gynecologic cancers is a major cause of mortality and morbidity and often presents with malignant ascites. Microscopic tumor spread can be demonstrated by a peritoneal wash cytology and help assess the prognosis of the disease. In our study, the roles of paraoxonase and ceruloplasmin, measured in peritoneal washing fluid of patients operated for gynecologic pathologies in differential diagnosis was investigated. Materials and Methods: Patients operated for malign or benign gynecologic pathologies in Antalya Education and Research Hospital Gynecology Clinic between 2010-2012 were included in the study. Samples were obtained during surgery. Results: A statistically significant difference was detected between patients with benign and malign diseases with regards to PON1 levels measured in peritoneal washing fluid (p:0.044), the average values being $64.2{\pm}30.8$ (Range 10.8-187.2) and $41.4{\pm}21.4$ (Range 10.4-95.5), respectively. No significant variation was evident for ceruloplasmin. Conclusions: Paraoxonase levels measured in peritoneal washing fluid may contribute to the differentiation of malign-benign diseases in gynecologic pathologies.

As the Covid-19 outbreak spreads and prolongs around the world, visitor lists are prepared in various ways when entering the facility to prevent infection and identify confirmed people. In this study, we propose an access management system using beacons to solve the problems with the preparation and management of existing visitor lists. The research method searches the laws related to the collection of personal information and compares the current status of personal information collection and trends in the beacons. The proposed system compares and analyzes existing methods and security and efficiency, which confirm accurate and rapid access registration. By using Beacon access management system, it is effective in preventing and responding to the spread of new infectious diseases in the future.

With the prolonged COVID-19 worldwide, it is essential to create a list of visitors when using various facilities to prevent the spread of COVID-19 and to investigate epidemiology in the event of confirmed cases. In the beginning, there were many problems due to the leakage of personal information and false preparation by making a list of visitors with a handwritten list. To compensate for the problems of handwritten lists, the KI-Pass system based on QR codes is mainly managed. However, KI-Pass systems have the disadvantages of issuing QR codes and abusing personal information. In this paper, we propose an access management system using beacon. Beacon is an close-range wireless communication device and visitors when they are near the facility and automatically registers their personal information on the cloud server for access management. It is expected that this will be effective in preventing and responding to the spread of new infectious diseases in the future.
