In light of SARS-CoV-2's significant impact, human society has experienced rapid changes in lifestyle that it has not yet experienced before. One way this virus has influenced people's lives is the emergence of the zero-contact society, an initiative for preventing the spread of infectious diseases. As can be seen, the social impact of COVID-19 is widespread. Various issues, such as those about government policy, personal information protection, and health care, are affecting society as a whole. At the same time, factual information is difficult to track and record because of the rapid and transient nature of related events and issues. As such, a method of effectively describing COVID-19 and real-time information is necessary. The "COVID-19: Our Memory" project is an attempt to record the sociocultural impact of the coronavirus infection. This project collects major events and issues classified into several subjects, records those events from a neutral point of view, and develops a digital archive so that all records are accessible. All the data collected and built through the project, the application, including the source code and visualization, are all published to bring about new opportunities for collaboration.

Prevalence of infectious agents, including Brucella abortus (BA), Mycobacterium bovis (MB), bovine leukemia virus (BLV), M. avium subsp. paratuberculosis (MP), Neospora caninum (NC) and Toxoplasma gondii (TG), was investigated in all the cattle raised in Ulleung island during 2007~2010. For BA, the prevalences in head and farm were 8.1% (44/545) and 5.5% (4/73) in 2007, all negative in 2008~2009, and 0.5% (4/774) and 1.7% (1/58) in 2010, respectively. For MB, no sample was positive by PPD or ELISA in 2007~2010. For BLV and MP, no sample was positive by ELISA in 2007~2009. For NC, seroprevalences in head and farm were 0.2% (1/545) and 1.4% (1/73), respectively, in 2007 and all negative in 2008~2009. For TG, seroprevalences in head and farm were 17.6% (97/552) and 54.8% (34/62) by ELISA in 2009. By regions, the seroprevalences of TG in Ulleung-eup, Seo-myeon and Buk-myeon were 26.0%, 9.8% and 16.7%, respectively, which had significant differences (P<0.0001). Tiger cattle were more resistant to TG infection than Hanwoo. The seroprevalence of TG in summer was higher than in autumn. The seroprevalence of TG in cows was higher than in oxen. The seroprevalence of TG in cattle was increased with age. In conclusion, this study indicates that the prevalences of six infectious diseases, except for TG which are widely spread, are relatively low in cattle reared in Ulleung island.

In contrast to juvenile laryngeal papillomatosis, which occurs most often in children and teenagers and is usually self limited, soliatry papillomas in adults are one of uncommon tumors of airway, and have a higher incidence of cancer. They are caused by the respiratory infection of human papilloma virus(HPV). They could spread to more distal airways and have a tendency of recurrence after limited surgical excision. Recently endoscopic therapies such as Nd-YAG laser, electrocautery, and cryotherapy provide extremely effective treatment modalities. We report a case of solitary tracheal papillomas in a 48 year-old man who presented with cough, scanty hemoptysis, and functional evidence of central airway obstruction. He was successfully treated by a Nd-YAG laser therapy via fiberoptic bronchoscopy under the local anesthesia.

Consultation with the patient and doctor is very important in the examination. However, if the consultation cannot be done directly, such as corona virus, it is difficult for the doctor to determine the patient's condition more accurately. Recently, an image counseling system has been developed based on the Internet, but in the case of heart disease, remote medical counseling cannot be performed because it is not possible to stethoscope the heart sounds remotely. In order to solve this problem, it is necessary to develop an interactive mobile robot capable of remote medical consultation, and a doctor and a patient should be able to set a planting sound during consultation and transmit it in real time. In this paper, we developed a robot that can remotely control a medical counseling robot to move to a hospital room where patients are hospitalized, and to consult a patient in the room remotely from a doctor's office. A remote medical imaging stethoscope system for real-time heart sound transmission is presented. The proposed system is a kind of P2P communication that transmits video information, audio information, and control signal independently through webRTC platform, so that there is no data loss. Consults and sees doctors in real time and finds it more effective than traditional methods for patient security. The system implemented in this paper will be able to perform remote medical care in the place where the spread of diseases between humans like the recent corona 19 as well as the remote medical care of heart disease patients in the future.

Internet network routing system is used to prevent spread and distribution of malicious data traffic. The penetration of malicious code and the function of security blocking are performed on the same course of traffic pathway. The security architecture is the concept to distinguish the architecture from the group handling with the traffic on the structure of network which is performed with the function of penetration and security. The security architecture could be different from the criterion of its realm and function, which requires the development and the application of security mechanism for every architecture. For the establishment of security architecture it is needed to show what criterion of net work should be set up. This study is based on analysis of diagnostic weakness structure in the network security architecture and research the criterion for topology factor, security architecture structure map selection, and blocking location and disinfection net. It is shown to increase the effective rate blocking the virus with the proposed method in this paper rather than the traditional network architecture.

Objectives: This report describes the results of an investigation on an outbreak of novel influenza A (H1N1) in an English language Institute in Seoul, Korea in May 2009. Methods: In this outbreak, novel influenza A (H1N1) was confirmed in 22 of 91 trainees, trainers and staff members. The trainees and 2 staff members were isolated in an assigned facility and the rest were isolated in their homes after we discovered the first patient with novel influenza A (H1N1). After the isolation, the people in the assigned facility were educated to use N95 respirators and they received oseltamivir for prophylaxis. Results: The initial findings in this study suggest that the symptoms were mild and similar to those of seasonal influenza. The classmates and roommates of the infected patients were more likely to get infected with novel influenza A (H1N1) than the trainees who were not classmates or roommates of the patients (OR: 3.19, 95% Cl=0.91 - 11.11 for classmates and OR: 40.0, 95% Cl=7.4-215.7 for roommates). Conclusions: The public health response seems successful in terms of preventing the spread of this virus into the local community.

Background: Arctic-like (AL) lineages of rabies viruses (RABVs) remains endemic in some Arctic and Asia countries. However, their evolutionary dynamics are largely unappreciated. Objectives: We attempted to estimate the evolutionary history, geographic origin and spread of the Arctic-related RABVs. Methods: Full length or partial sequences of the N and G genes were used to infer the evolutionary aspects of AL RABVs by Bayesian evolutionary analysis. Results: The most recent common ancestor (tMRCA) of the current Arctic and AL RABVs emerged in the 1830s and evolved independently after diversification. Population demographic analysis indicated that the viruses experienced gradual growth followed by a sudden decrease in its population size from the mid-1980s to approximately 2000. Genetic flow patterns among the regions reveal a high geographic correlation in AL RABVs transmission. Discrete phylogeography suggests that the geographic origin of the AL RABVs was in east Russia in approximately the 1830s. The ancestral AL RABV then diversified and immigrated to the countries in Northeast Asia, while the viruses in South Asia were dispersed to the neighboring regions from India. The N and G genes of RABVs in both clades sustained high levels of purifying selection, and the positive selection sites were mainly found on the C-terminus of the G gene. Conclusions: The current AL RABVs circulating in South and North Asia evolved and dispersed independently.

In this paper, we consider a rumor source inference problem when sufficiently many nodes heard the rumor in the network. This is an important problem because information spread in networks is fast in many real-world phenomena such as diffusion of a new technology, computer virus/spam infection in the internet, and tweeting and retweeting of popular topics and some of this information is harmful to other nodes. This problem has been much studied, where it has been shown that the detection probability cannot be beyond 31% even for regular trees if the number of infected nodes is sufficiently large. Motivated by this, we study the impact of query that is asking some additional question to the candidate nodes of the source and propose budget assignment algorithms of a query when the network administrator has a finite budget. We perform various simulations for the proposed method and obtain the detection probability that outperforms to the existing prior works.

With the spread of Corona virus l spreading to the uncertainty of society, consumers request more active social responsibility programs. In other words, it is manifest that corporate brands are required to pursue the public interests. Consumers go beyond the corporate social responsibility programs and support corporate's involvement to solve the social problems and they consume the brand accordingly. Thus, the companies respond to the consumers' request as a form of brand activism, or the new social marketing form in which the companies set the brand as an individual and seek the solutions of social issues. In this study, five experienced experts in the area were recruited to conduct in-depth interviews and how brand activism was practiced worldwide. The results reveal that brand activism is actively practiced with the support of consumers in the area of support for the small business, anti-racism efforts, gender diversity and equality, and sustainability.
