African swine fever (ASF), caused by the ASF virus, a member of the Asfarviridae family, is one of the most important diseases in the swine industry due to its clinical and economic impacts. Since the first report of ASF a century ago, ample information has become available, but prevention and treatment measures are still inadequate. Two waves of epizootic outbreaks have occurred worldwide. While the first wave of the epizootic outbreak was controlled in most of the infected areas, the second wave is currently active in the European and Asian continents, causing severe economic losses to the pig industry. There are different patterns of spreading in the outbreaks between those in European and Asian countries. Prevention and control of ASF are very difficult due to the lack of available vaccines and effective therapeutic measures. However, recent outbreaks in South Korea have been successfully controlled on swine farms, although feral pigs are periodically being found to be positive for the ASF virus. Therefore, we would like to share our story regarding the preparation and application of control measures. The success in controlling ASF on farms in South Korea is largely due to the awareness and education of swine farmers and practitioners, the early detection of infected animals, the implementation of strict control policies by the government, and widespread sharing of information among stakeholders. Based on the experience gained from the outbreaks in South Korea, this review describes the current understanding of the ASF virus and its pathogenic mechanisms, epidemiology, and control.

A vegetative filter strip (VFS) is one of the best management practices (BMPs) to reduce pollutant loads. This study aims to assess the effectiveness of VFS in dense upland field areas. The study areas are agricultural fields in the Maedae (MD), Gaa (GA), and Jaun (JU) watersheds, where severe sediment yields have occurred and the Korean government has designated them as non-point management regions. The agricultural fields were divided into three or four clusters for each watershed based on their slope, slope length, and area (e.g., MD1, MD2). To assess the sediment trapping (STE) and pesticide reduction efficiency (PRE) of VFS, the Vegetative Filter Strip Modeling System (VFSMOD) was applied with three different scenarios (SC) (SC1: VFS with rye vegetation; SC2: VFS with rye vegetation and a gentle slope in VFS range; and SC3: VFS with grass mixture). For SC1, there were relatively short slope lengths and small areas in the MD1 and GA3 clusters, and they showed higher pollutant reduction (STE>50%, PRE>25%). For SC2 and SC3, all clusters in GA and some clusters (MD1 and MD3) in MD show higher pollutant reduction (>25%), while the uplands in JU still show a lower pollutant (<25%). With correlation analysis between geographic characteristics and VFS effectiveness slope and slope length showed relative higher correlations with the pollutant efficiency than a area. The results of this study implied that slope and slope length should be considered to find suitable upland conditions for VFS installations.

The food cold chain refers to a technology and distribution supply chain applied to maintain a constant temperature suitable for the product from production (harvest) to delivery to consumers. In particular, in Korea, the insulation material used in the food cold chain is mostly EPS (Expanded Polystyrene), which is used as a transport container for various food cold chains. However, according to the government's eco-friendly policy, companies charge environmental contributions to the use of EPS, but due to its low price and convenience of handling, it is still used as a container for delivering food. In this study, in order to measure the domestic delivery environment of general refrigerated foods, changes in impact, temperature, and humidity during transport of the EPS packaging system containing foods and ice pack refrigerants were measured. As a result, there were 2?3 sections in which a high impact force of 40 G or more was generated during transport. This can cause damage to the product and EPS container. The difference in temperature and humidity changes by parcel transport routes is more than 30%, so it is necessary to present accurate standards for the domestic cold chain distribution environment. As a result of microbial experiments. the transportation period had a dominant effect on the increase in total viable count and E. coli count.
In the era of the fourth industrial revolution technology, the inclusion of personalized nutrition for healthcare (PNH), when establishing a healthcare platform to prevent chronic diseases such as obesity, diabetes, cerebrovascular and cardiovascular disease, pulmonary disease, and inflammatory diseases, enhances the national competitiveness of global healthcare markets. Furthermore, since the government experienced COVID-19 and the population dead cross in 2020, as well as numerous health problems due to an increasing super-aged Korean society, there is an urgent need to secure, develop, and utilize PNH-related technologies. Three conditions are essential for the development of PNH technologies. These include the establishment of causality between obesity genome (genotype) and prevalence (phenotype) in Koreans, validation of clinical intervention research, and securing PNH-utilization technology (i.e., algorithm development, artificial intelligence-based platform, direct-to-customer [DTC]-based PNH, etc.). Therefore, a national control tower is required to establish appropriate PNH infrastructure (basic and clinical research, cultivation of PNH-related experts, etc.). The post-corona era will be aggressive in sharing data knowledge and developing related technologies, and Korea needs to actively participate in the large-scale global healthcare markets. This review provides the importance of scientific evidence based on a huge dataset, which is the primary prerequisite for the DTC obesity gene-based PNH technologies to be competitive in the healthcare market. Furthermore, based on comparing domestic and internationally approved DTC obese genes and the current status of Korean obesity genome-based PNH research, we intend to provide a direction to PNH planners (individuals and industries) for establishing scientific PNH guidelines for the prevention of obesity.

Objectives: Discussions regarding "medical blind spots" in Korea's "aging society" are continuously rising. In addition, the demand for medical attention and care for the elderly and vulnerable populations continues to increase. Given this, the government is promoting the "home healthcare service" project. This study aims to lay the foundation for promoting this project by investigating the perception of clinical Korean Medicine (KM) doctors in the "community health care" project. Methods: With the cooperation of the Association of Korean Medicine, we sent a questionnaire to all KM doctors through e-mail. The survey included personal information, awareness, appropriate disease and intervention, proper visit location, and pros and cons. Results: A total of 602 responses were collected and analyzed. Approximately 20% of the doctors answered that they were well aware of the service, while 55% responded that they did not know about it. For a visit, a KM doctor selected the appropriate diseases in the order of stroke, dementia and Parkinson's disease, osteoarthritis, and chronic diseases. Among treatments, acupuncture, moxibustion, and herbal medicine exhibited similar results. The most common opinion was that KM doctors should schedule their visits once a week for 6-12 months, which was the most prolonged period among the given options. More than 80% (84.1%) of the doctors replied that care projects were highly essential, and about 63.8% expressed their willingness to participate in these projects. Conclusion: To provide appropriate home health care, we must raise awareness among Korean medicine doctors. In addition, the healthcare budget must be increased to provide the required support.

The South Korean ethnic diaspora US lobby shows efficacy as an interest group in generating influence in American foreign and domestic public policy making. The persuasive portrayal of South Korea as a critical Cold War US ally reinforced US amenability to pro-South Korea lobbying. Also, the South Korean US diaspora is a comparatively recent immigrant group, thus its lingering resistance to assimilation facilitates its political mobilization to lobby the US government. One source of this influence includes the foundational legacy of proselytizing Western and particularly American religious social movement representatives in Korean religiosity and society. US protestant Christianity acquired a strong public association with emerging Korean nationalism in response to Japanese imperialism and occupation. Hostility towards Japanese colonialism followed by the threat from Soviet-sponsored, North Korean Communism meant Christianity did not readily become a cultural symbol of excessive external, US interference in South Korean society by South Korean public opinion. The post-Cold War shift in US foreign policy towards targeting so-called rogue state vestiges of the Cold War including North Korea enhanced further South Korea's influence in Washington. Due to essential differences in the perceived historical role of American influence, extrapolation of the South Korean development model is problematic. US hegemony in South Korea indicates that perceived alliance with national self-determination constitutes the core of soft power appeal. Civilizational appeal per se in the form of religious beliefs are not critically significant in promoting American polity influence in target polities in South Korea or, comparatively, in the Middle East. The United States is a perceived opponent of pan-Arab nationalism which has trended towards populist Islamic religious symbolism with the failure of secular nationalism. The pronounced component of evangelical Christianity in American core community nationalism which the Trump campaign exploited is a reflection of this orientation in the US.
Simulation-based acquisition(SBA) is a new acquisition paradigm to deliver combat systems cheaper, faster, and better. ROK MND adopts the vision of SBA and is pushing ahead with dramatic reform. However, ROK MND does not develop the SBA architecture framework which facilitates the reuse of tools and techniques and data software code and algorithms among participants of collaborative environments. In this paper, we propose a conceptual Model of architecture framework for SBA. To do so, we analyse acquisition process of MND and propose the to-be operational view that describes fundamental concept for how Government, Industry, and Academia can collaborate and share information more effectively throughout the acquisition process. Furthermore, we identify the tools and techniques that supports the operational nodes, and propose technical view and all view, too. technical view compose of set of standards that can ensure interoperability among tools, techniques and data, and all view provide an overarching description of the architecture.
This paper surveys research since the 1990s on the ability of the yield spread and its components (i.e., expectation spread and term premium components) for future economic activity, and also conducts an empirical analysis of their forecasting ability using the yield data of Korean government bonds. This paper's survey, particularly for the US, shows that the yield spread has significant predictive power for some macroeconomic variables, but since the mid-1980s, its predictive power seems to have declined, possibly due to stronger inflation targeting. Next, this paper's empirical analysis using Korean data indicates that the yield spread, and the term premium component in particular, has significant predictive power for industrial production (IP) growth, consumer price index growth, and the IP gap. An out-of-sample analysis shows that the prediction equations are unstable over time, and that in predicting IP growth, the yield spread decomposition makes a significant contribution to the prediction of IP growth.

Nanotechnology in the food industry can increase the effectiveness of food ingredients. Nanotechnology can increase the bioavailability and absorption of bioactive compounds, enhance their stability, and improve the sensory quality of the product. Processed meat products are easily damaged due to bacterial activity. Advanced nanoemulsions as a meat preservative are nanoemulsions that can be used as preservative agents in meat products, particularly essential oil nanoemulsions, due to their antimicrobial and antioxidant properties. Its application is still limited to foods made from meat products. Therefore, this literature review examines nanoemulsion and its application in meat products and functionality improvement. Also, in the future, nanoemulsions in meat products must be made safe, and the government and businesses must work together to build consumer trust. It can be concluded that essential oil-based nanoemulsion has the potential to be used as an additive in meat products because it can kill bacteria, fight free radicals, improve flavor, and keep food fresh. Nanoemulsion is challenging in the meat industry because it can be toxic due to its tiny droplets (under 200 nm).
Purpose: This study investigated the vulnerability to human immunodeficiency virus (HIV) infection and associated factors among married women in northwest Ethiopia. Methods: A community-based cross-sectional survey (n=657) was conducted from April 1 to 15, 2020, in Metema District, northwest Ethiopia, in four randomly selected kebele administrations (the lowest level of local government). The inclusion criteria were married women aged ≥18 years residing with their husbands. Logistic regression analysis was conducted to identify factors associated with married women's vulnerability to HIV infection. Results: Participants were on average 33.70±9.50 years and nearly one-fourth (n=148, 22.5%) were identified as vulnerable to HIV infection (i.e., experienced sexually transmitted disease symptoms or an extramarital affair of either spouse within the past 12 months). Only 18.9% reported sexual communication with their husband. Respondents who did not discuss the risk of HIV infection with their husbands had fivefold odds of vulnerability (adjusted odds ratio [AOR], 5.02; 95% confidence interval [CI], 1.43-17.5). Those who did not have premarital sex (AOR, 0.20; 95% CI, 0.05-0.77) had no worries about HIV infection (AOR, 0.27; 95% CI, 0.08-0.94), sufficient income (AOR, 0.56; 95% CI, 0.16-0.86), and less than four children (AOR, 0.69; 95% CI, 0.50-0.97) had decreased odds of being vulnerable to HIV than their counterparts. Conclusion: Not discussing risk of HIV infection with husband was a major factor of vulnerability to HIV infection as was premarital sex, worry about HIV, income, and number of children. Measures to strengthen couple's sexual communication and support economical stability is important for decreasing HIV vulnerability.
