Coronavirus has been spreading rapidly around the world since it broke out in China in 2019. Respiratory diseases caused by coronavirus infection cause various diseases ranging from asymptomatic subclinical infections to severe pneumonia and cardiovascular complications, leading to death. In this regard, natural products are being studied to prevent various diseases caused by COVID-19. In current review, we would like to present mechanisms related to the inhibition of heart disease in ginseng and ginsenoside against SARS-CoV-2. In many previous studies, ginseng and ginsenoside are known to have antioxidant, blood flow improvement, improvement of vascular and heart function, blood pressure control, suppression of myocardial infarction and heart failure, and antiarrhythmia. Therefore, ginseng and ginsenoside have a possibility to suppress cardiovascular complications caused by COVID-19. Many of research provide evidence for ginseng and ginsenoside as treatments for the risk of cardiovascular complications. However, in this review, more specific contents on the proposition of the efficacy of ginseng and ginsenoside for COVID-19 should be presented. Therefore, we hope that researches to reduce cardiovascular complications of ginseng and ginsenoside for COVID-19 should be presented to reduce mortality for COVID-19.

Religious organizations execute various social welfare programs on the basis of their religious ideology and faith. Their practice vividly aim at mission, propagation, edification, and spreading, but also is practised as a way of philanthropy, an universal value. Daesoonjinrihoe's social welfare program can be understood in this respect. This paper investigates on which idea Daesoonjinrihoe's social welfare program takes its basis, and examines the current situation and tasks of the social welfare program. Daesoonjinrihoe runs their social welfare program on the idea of 'Resolution of grievances for the mutual beneficence of all life[Haewonsangsaeng: 解冤相生]' and 'Boeunsangsaeng(報恩相生)'. Their program is concentrated on medical welfare, welfare for elderly people, and youth welfare. It is noteworthy that Daesoonjinrihoe's welfare program is not subsidized by government as much as those of other religious organizations. This paper looks into the tasks for Daesoonjinrihoe's social welfare program in terms of operational system and hardware, and suggests that we need to show interest in multicultural welfare systems and support it as Korean society is becoming a more multicultural society.

Recently, Podaegi, a traditional Korean childcare product, are spreading abroad like a trend. Sites specializing in the sale of ' Podaegi have been created in the UK, France, and the US, and their popularity is increasing. In addition, China's preference for safe products and demand for global products and premium baby products are rapidly increasing. Nevertheless, the proportion of baby products in Korea is still very small. Therefore, this study seeks to find the differentiated value and direction of development of Podaegi by finding a form and method similar to Podaegi and overseas. The research method was reviewed based on literature research and actual cases. As a result, Podaegi has high practicality and emotional value, and attachment parenting is possible. When the stages of attachment parenting were compared and analyzed, it was confirmed that attachment parenting is possible for a wider age group than others, and that Korean traditional Podaegi has developed differently from Western ones, and that Korean Podaegi is very advantageous for attachment parenting. Therefore, in the future, Korea's Podaegi needs to meet overseas import standards, propose designs that fit the current situation, and promote and develop differentiated values abroad.

Purpose - In Korea, there has been a recent trend that shows housing prices have risen rapidly following the International Monetary Fund crisis. The rapid rise in housing prices is spreading recognition of this as a factor in housing price volatility. In addition, this raises the expectations of housing prices in the future. These expectations are based on the assumption that a relationship exists between the current housing prices and expected housing prices in the real estate industry. By performing an empirical analysis on the validity of the claim that an increase in current housing prices can be correlated with expected housing prices, this study examines whether a long-term equilibrium relationship exists between expected housing prices and existing housing prices. If such a relationship exists, the recovery of equilibrium from disequilibrium is analyzed to derive related implications. Research design, data, and methodology - The relationship between current housing prices and expected housing prices was analyzed empirically using the Vector Error Correction Model. This model was applied to the co-integration test, the long-term equilibrium equation among variables, and the causality test. The housing prices used in the analysis were based on the National Housing Price Trend Survey released by Kookmin Bank. Additionally, the Index of Industrial Product and the Consumer Price Index were also used and were obtained from the Bank of Korea ECOS. The monthly data analyzed were from January 1987 to May 2015. Results - First, a long-term equilibrium relationship was established as one co-integration between current housing price distribution and expected housing prices. Second, the sign of the long-term equilibrium relationship variable was consistent with the theoretical sign, with the elasticity of housing price distribution to expected housing price, the industrial production, and the consumer price volatility revealed as 1.600, 0.104,and 0.092, respectively. This implies that the long-term effect of expected housing price volatility on housing price distribution is more significant than that of the industrial production and consumer price volatility. Third, the sign of the coefficient of the error correction term coincided with the theoretical sign. The absolute value of the coefficient of the correction term in the industrial production equation was 0.006, significantly larger than the coefficients for the expected housing price and the consumer price equation. In case of divergence from the long-term equilibrium relationship, the state of equilibrium will be restored through changes in the interest rate. Fourth, housing-price volatility was found to be causal to expected housing price, and was shown to be bi-directionally causal to industrial production. Conclusions - Based on the finding of this study, it is required to relieve the association between current housing price distribution and expected housing price by using property taxes and the loan-to-value policy to stabilize the housing market. Further, the relationship between housing price distribution and expected housing price can be examined and tested using a sophisticated methodology and policy variables.

The objective of the current study was to investigate the effect of odor reducing agents on the levels of pH, total carbon, total nitrogen, and odorous compounds [phenols, indoles, short chain fatty acid (SCFA), branched-chain fatty acid (BCFA), and ammonium nitrogen] of swine manure during the spring season (temperature around $20^{\circ}C$). Odor reducing agents included horseradish powder, mushroom waste powder, and almond hull powder. A manure sample (15 L) was taken from the pit under the pens of a swine feeding operation and incubated with 0.03% horseradish powder, 1% mushroom waste powder, and 1% almond hull powder, respectively, in acryl chambers for 14 days. Addition of almond hull powder showed the lowest pH (p < 0.05) and the highest level of total carbon (p < 0.05) among treatments of odor reducing agents. Although addition of odor reducing agents increased the level of phenols (p < 0.05), addition of almond hull powder decreased the level of indoles (p < 0.05). Levels of SCFA and BCFA were higher in almond hull powder than those in control (p < 0.05). Taken together, the results from our current study showed that odor reducing agents can be used for reducing the odor of swine manure by providing fermentable carbohydrates. At $20^{\circ}C$, however, the function of odor reducing agents might be decreased due to lower microbial activity.

The novel coronavirus disease 2019 (COVID-19) is spreading globally. Although its etiologic agent is discovered as severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), there are many unsolved issues in COVID-19 and other infectious diseases. The causes of different clinical phenotypes and incubation periods among individuals, species specificity, and cytokine storm with lymphopenia as well as the mechanism of damage to organ cells are unknown. It has been suggested that in viral pneumonia, virus itself is not a direct cause of acute lung injury; rather, aberrant immune reactions of the host to the insults from viral infection are responsible. According to its epidemiological and clinical characteristics, SARS-CoV-2 may be a virus with low virulence in nature that has adapted to the human species. Current immunological concepts have limited ability to explain such unsolved issues, and a presumed immunopathogenesis of COVID-19 is presented under the protein-homeostasis-system hypothesis. Every disease, including COVID-19, has etiological substances controlled by the host immune system according to size and biochemical properties. Patients with severe pneumonia caused by SARS-CoV-2 show more severe hypercytokinemia with corresponding lymphocytopenia than patients with mild pneumonia; thus, early immunomodulator treatment, including corticosteroids, has been considered. However, current guidelines recommend their use only for patients with advanced pneumonia or acute respiratory distress syndrome. Since the immunopathogenesis of pneumonia may be the same for all patients regardless of age or severity and the critical immune-mediated lung injury may begin in the early stage of the disease, early immunomodulator treatment, including corticosteroids and intravenous immunoglobulin, can help reduce morbidity and possibly mortality rates of older patients with underlying conditions.

Antimicrobial (AM) resistance is a growing threat in human and veterinary medicine, spreading across species and perceived as One-Health issue. Prudent use of AM products is essential in mitigating this risk in both human and veterinary medicine. Farm veterinarians, responsible for prescribing appropriate AM and offering advice to farmers on their proper usage, are regarded as key players in the livestock industry. An online survey of farm veterinarians (n = 1,531) was conducted to assess their educational experience, beliefs, current status of prescription, practical behavior, and self-efficacy regarding the prudent use of antimicrobials (PUA). The data from 170 respondents were analyzed using descriptive statistics, regression and mediation analysis. Participants chose AM based on their experiences, academic resources, and peer veterinarians. Approximately 77% did not routinely conduct antibiotic-susceptibility-test. Most participants believed in the importance of PUA and the role of veterinarians to reduce AM resistance, but they reported a lack of awareness among farmers and insufficient national support interfere with their practical behavior with regard to PUA. Half of the participants had PUA-education, and 78.6% reported that education had a positive impact on their behavior with PUA. Self-efficacy partly mediates the relationship between belief and behavior for PUA, which accounted for 23.77% of the total effect that beliefs have on behavior for PUA. The findings of the study show that enhancing veterinarians' abilities to practice and their self-efficacy through education tailored to the current status of farms can contribute to the reduction of AMs in the livestock sector.
