The purpose of this study is two-fold: first, to discuss the concept of health diplomacy and the Korean government's response to contain the COVID-19 pandemic; second, to assess and compare assumptions of variances about foreigners' perceptions of how Korea is leveraging digital technology in battling the coronavirus spread, and its vaccine campaign; through the lenses of Chinese, Filipino, and Pakistani foreign nationals who are currently living in Korea. A total of 219 foreigners responded to the survey. The collected data were analyzed as percentages, mean averages, t-test, and ANOVA for statistical analysis. Results show that Korea is utilizing its digital technology practices and vaccine campaign in battling the pandemic through efforts of health diplomacy. ANOVA indicated significant results and assumptions of variance across three ethnic groups showing the Pakistani population had higher mean scores than the Chinese and Filipino about Korea's health diplomacy during the pandemic. This study contributes to the literature on Korea's digital technology practices and vaccine campaigns amidst the COVID-19 pandemic by promoting its image through health diplomacy efforts. It projects the country's soft image on a global scale, to save the lives of locals and foreign nationals, by providing insights into health diplomacy in Korea.

Viral infectious diseases have been regarded as one of the greatest threats to global public health. The recent coronavirus disease 2019 (COVID-19) pandemic caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is a stark reminder of the threat posed by emerging viral infections. Developing and producing appropriate and efficient vaccines and therapeutics are the only options to combat this pandemic. The COVID-19 pandemic has highlighted the need for novel vaccine platforms to control and prevent emerging viral diseases. Conventional vaccine platforms, including live-attenuated vaccine and inactivated vaccines, pose limitations in the speed of vaccine development, manufacturing capacity, and broad protection for emergency use. Interestingly, vaccination with the SARS-CoV-2 vaccine candidate based on the mRNA-lipid nanoparticle (LNP) platform protected against COVID-19, confirming that the nucleoside-modified candidate is a safe and effective alternative to conventional vaccines. Moreover, the prophylactic strategies against the COVID-19 pandemic have been mRNA nucleic acid-based vaccines and nanoparticle-based platforms, which are effective against SARS-CoV-2 and its variants. Overall, the novel vaccine platform has presented advantages compared with the traditional vaccine platform in the COVID-19 pandemic. This review explores the recent advancements in vaccine technologies and platforms, focusing on mRNA vaccines, digital vaccines, and nanoparticles while considering their advantages and possible drawbacks.

Early and accurate detection of pathogens is important to improve clinical outcomes of bloodstream infections (BSI), especially in the case of drug-resistant pathogens. In this study, we aimed to develop a culture-independent digital PCR (dPCR) system for multiplex detection of major sepsis-causing gram-negative pathogens and antimicrobial resistance genes using plasma DNA from BSI patients. Our duplex dPCR system successfully detected nine targets (five bacteria-specific targets and four antimicrobial resistance genes) through five reactions within 3 hours. The minimum detection limit was 50 ag of bacterial DNA, suggesting that 1 CFU/ml of bacteria in the blood can be detected. To validate the clinical applicability, cell-free DNA samples from febrile patients were tested with our system and confirmed high consistency with conventional blood culture. This system can support early identification of some drug-resistant gram-negative pathogens, which can help improving treatment outcomes of BSI.

It has been reported that some exercise could enhance the anti-viral antibody titers after vaccination including influenza and coronavirus disease 2019 vaccines. We developed SAT-008, a novel digital device, consists of physical activities and activities related to the autonomic nervous system. We assessed the feasibility of SAT-008 to boost host immunity after an influenza vaccination by a randomized, open-label, and controlled study on adults administered influenza vaccines in the previous year. Among 32 participants, the SAT-008 showed a significant increase in the anti-influenza antibody titers assessed by hemagglutination-inhibition test against antigen subtype B Yamagata lineage after 4 wk of vaccination and subtype B Victoria lineage after 12 wk (p<0.05). There was no difference in the antibody titers against subtype "A." The SAT-008 also showed significant increase in the plasma cytokine levels of IL-10, IL-1β, and IL-6 at weeks 4 and 12 after the vaccination (p<0.05). A new approach using the digital device may boost host immunity against virus via vaccine adjuvant-like effects.

The use of mobile devices offers a variety of services to the individuals and companies. On the other hand, security threats and new mobile security threats that exist in IT infrastructure to build the environment for mobile services are present at the same time. Services such as mobile and vaccine management services, such as MDM (Mobile Device Management) has attracted a great deal of interest in order to minimize the threat of security in mobile environment. These solutions can not protect an application that was developed for the mobile service from the threat of vulnerability of mobile application itself. Under these circumstances, in this paper, we proposed mobile application security checklists based on application security review items in order to prevent security accidents that can occur in a mobile service environment. We collected and analyzed Android applications, we performed a total inspection of the applications for verification of the effectiveness of the check items. And we checked that the check items through a survey of experts suitability was verified.

This research attempted to identify the factors associated with the intention of human papilloma virus vaccination among mothers of elementary school daughters. The subject of study is 132 mothers of elementary school students. Data collection was conducted from July 1 to August 30 in 2017, and analyzed using SPSS 23.0 Program. Results showed that 94.7% children of the participants had not been vaccinated, whose reasons were the low knowledge about HPV vaccination, concerns about its side effects, burden for cost. The attitude toward HPV vaccination appeared to be the most important predictor of vaccination, which was followed by perceived behavior control and subjective norm as meaningful predictors, as well. Based on these results, further researches should be conducted to develop educational programs, which are able to offer exact information about the effect and side effect of HPV vaccination, and verify the effectiveness.

After the COVID-19 outbreak in 2019, the spread of COVID-19 has not been easily caught despite preventive measures in each country. The spread of COVID-19 has hit the world, especially in the economic and tourism sectors. Countries around the world are easing restrictions on the movement of vaccinated people in preparation for the post-corona era. Under the name of "Vaccine Passport," "Vaccination Certificate," and "Digital Health Pass," vaccination measures are being implemented to allow vaccination recipients to use multi-use facilities. However, there is no international agreement on the movement of countries, and each country has its own immigration policy. In order to return to pre-corona daily life, global agreements must be reached from the movement of vaccinated people between countries, and standards and implementation methods must be determined. This study focuses on the implementation and utilization of vaccination certificates suitable for the COVID-19 era. We will look at the spread of COVID-19 and its international response policies. In the case of COVID-19, we will investigate why vaccination certificate installation should be standardized and how far the current standardization has been discussed, and discuss the characteristics of vaccination certificate installation and considerations. In order for the immunization certificate discussed in the previous chapter to be recognized internationally, institutional and technical considerations are identified and security factors that may occur in each implementation are also presented. Finally, the international recognition case of vaccination certificate is discussed, and the method of installation and utilization of vaccination certificate is proposed. This paper can be used as a policy because of its timeliness in studying the standards of vaccination certificates and considerations for international recognition to restore movement between countries in the spread of COVID-19. In addition, if other infectious diseases occur in the future or similar cases where movement between countries is restricted, it can be used as a reference to support the movement of verified people.

Tertomotide is a peptide fragment of hTert and developed as a vaccine targeting cancer. It has been reportedly known to ameliorate inflammatory symptoms in clinical tests and in animal studies. However, the therapeutic potential of tertomotide is not supposed to be comparable to conventional anti-inflammatory agents due to low druglikeness In order to treat inflammations present in varous lesion, the structure of tertomotide is required to be modified. In this context, 12 octapeptides were designed based on tertomotide and screened for the anti-inflammatory activity in activated monocyte by measuring TNF-α secretion. As a result, some octapeptides has been exerted anti-inflammatory activity, comparable to or better than tertomotide and estradiol, known anti-inflammatory agents. This result is supposed to be helpful for developing therapeutic purpose exploiting other tertomotide-derived peptides and would be an example for designing novel drug based on active biomolecules with undesirable structure by convergence study of biology and computer-aided medicinal chemistry.
