  • This paper presents the infectious watermarking model (IWM) for the protection of video contents that are based on biological virus modeling by the infectious route and procedure. Our infectious watermarking is designed as a new paradigm protection for video contents, regarding the hidden watermark for video protection as an infectious virus, video content as host, and codec as contagion medium. We used pathogen, mutant, and contagion as the infectious watermark and defined the techniques of infectious watermark generation and authentication, kernel-based infectious watermarking, and content-based infectious watermarking. We experimented with our watermarking model by using existing watermarking methods as kernel-based infectious watermarking and content-based infectious watermarking medium, and verified the practical applications of our model based on these experiments.

  • Due to the global epidemic of infectious diseases, it has become important for all industries to respond to the risk of infectious diseases. Ports in each country are also responding to the risk of infectious diseases, but the occurrence of infectious diseases in ports of various countries is causing a lot of damage to the logistics of ports. Korea is in the same situation, and cases of infectious diseases in ports are steadily being announced. Therefore, this paper conducted semi-quantitative Bow-Tie risk assessment by substituting measures to cope with infectious disease risks in Korean ports into actual cases of port infectious diseases in Korea, deriving improvements and suggesting directions. As a result, it was concluded that it was necessary to standardize some of the countermeasures against infectious diseases and develop more countermeasures.

  • We have carried out collaborative study to evaluate a preparation of antithrombin concentrate whether or not it was suitable to serve as the candidate for a Korea National Biological Standard. Six laboratories. including three manufacturers and three National Control Laboratories. participated in this study. The potency of this candidate preparation was determined using the heparin cofactor chromogenic method. (omitted)

  • Purpose: This study tried to present basic data for establishment of facility guidelines and facility certification standards for the comprehensive prevention of infectious diseases in buildings. Methods: This study examines the concept of architectural countermeasures for the prevention of infectious diseases through literature reviews, and then classifies and organizes the countermeasures by viewing the infectious diseases hospitals as the top-level facility in terms of responding to infectious diseases. Results: At first, this study categorized and organized infection prevention countermeasures of infectious disease hospitals, which are the highest level facilities in terms of response to infectious diseases. And by presenting the concept of step-by-step setting of countermeasures for general buildings such as welfare facilities and multi-use facilities, which are lower-level facilities in the aspect of prevention of infectious diseases, this study tried to present basic data for establishing facility guidelines and facility certification standards for comprehensive prevention of infectious diseases in buildings. Implications: In the future, it is expected that spatial changes for the prevention of infectious diseases will spread to general constructions such as public buildings, private buildings, and multi-use facilities, and comprehensive infection prevention facility guidelines are needed.

  • Tuberculosis (TB) is a major infectious disease that threatens the life and health of people globally. Here, we performed a metabolomic analysis of serum samples from patients with intractable TB to identify biomarkers that might shorten the TB treatment period. Serum samples collected at the commencement of patients' treatment and healthy controls were analyzed using the capillary electrophoresis and time-of-flight mass spectrometry metabolome analysis method. The analysis identified the metabolites cystine, kynurenine, glyceric acid, and cystathionine, which might be useful markers for monitoring the TB treatment course. Furthermore, our research may provide experimental data to develop potential biomarkers in the TB treatment course.

  • The hepatitis E virus (HEV) is a leading causative agent of acute hepatitis in humans. Zoonotic HEV strains have been isolated from several animal species, including pigs. New HEV variants have been recently isolated from camels in the Middle East. In the present study, fecal samples from fallow deer, formosan deer, alpaca, and guanaco were analyzed for the detection of HEV. One HEV strain was detected from guanaco, a species of camelids. The nucleotide sequence of guanaco HEV was identical to those of deer HEV-3 strains, which implied the cross-species transmission of HEV-3 from deer to guanaco.
