The purpose of this study was to analyze Korean Women's U.S. Ph.D. Degree-seeking Process and career development in the field of science and engineering in the United States. We conducted the analysis on the basis of SED (Survey of Earned Doctorates) data of the National Science Foundation. Since 2001, the number of Korean Ph.D. degree recipients from United States universities has been increasing and about 25% of them were women. Their median age was 33.3 years old, and one third of them were the recipients of research and teaching assistantships while pursuing a Ph.D. degree. At the time of receiving the degree, 51.8% reported having definite commitments for employment or postdoctoral study or research. Over 70% of the degree holders were presumed to stay and work in the United States. The study finally addressed policy implications regarding their recruitment to Korea and a need for a longitudinal survey.

Korea is one of the top countries that has funded great amount to promote basic research and others in recent decade. While the quantity of R&D fund in Korea has rapidly increased, the effectiveness and quality of R&D outcomes became a controversial issue. National Research Foundation of Korea (NRF) and Korea Environmental Industry & Technology Institute (KEITI) agreed to collaborate for diffusing and utilizing R&D outcomes of each institute. NSF and KEITI signed the bilateral MOU in 2012, and Interministerial Collaborative R&D Support Framework (ICR&DSF) was developed. The ICR&DSF consist of launching an Eco-Bridge Program as an interministerial R&D program and composition of Environmental Convergence R&D Bridge Committee. The Eco-Bridge Program was applied to 'Environmental Convergence Technology Project' of KEITI as a pilot program in 2012. The unique feature of this interministerial R&D program is that the Eco-Bridge Program directly supports the basic research outcomes which are previously funded by NRF. As the collaboration between NRF and KEITI becomes stronger, it is expected to explore the more creative and the more transformative research.

The objective of this study was to determine the effect of bacterial inoculation (Lactobacillus plantarum or combo inoculant mixed with Lactobacillus plantarum and Lactobacillus buchneri) and addition of fibrolytic enzyme on chemical compositions and fermentation characteristics of whole crop barley (WCB) and triticale (TRT) silage, their ruminal in vitro fermentation, and digestibility. In TRT silage, enzyme addition significantly (p<0.01) decreased NDF content compared to no enzyme addition treatment. Organic acids such as lactate and acetate contents in WCB and TRT silages were significantly (p<0.01) higher compared to those in the control. Particularly, lactate content was the highest in L. plantarum treatment. Fibrolytic enzyme treatment on both silages had relatively higher lactic acid bacteria content, while mold content was lower in both treatments compared to that in the control. In vitro dry matter digestibility was generally improved in WCB silages. It was higher (p<0.01) in TRT with mixed treatment of L. plantarum, L. buchneri, and enzyme compared to others. In vitro ruminal acetate production was relatively higher in treatments with both enzyme and inoculant additions compared to that in the control. Therefore, the quality of silage and rumen fermentation could be improved by inoculants (L. plantarum and L. buchneri) regardless whether whole crop barley (WCB) or triticale (TRT) silage was used. Although it was found that fibrolytic enzyme addition to both silages had various quality and rumen fermentation values, further study is needed.

The world is suffering from numerous human and economic losses due to the novel coronavirus infection (COVID-19). The Korean government established a strategy to overcome the national infectious disease crisis through research and development. It is difficult to find distinctive features and changes in a specific R&D field when using the existing technical classification or science and technology standard classification. Recently, a few studies have been conducted to establish a classification system to provide information about the investment research areas of infectious diseases in Korea through a comparative analysis of Korea government-funded research projects. However, these studies did not provide the necessary information for establishing cooperative research strategies among countries in the infectious diseases, which is required as an execution plan to achieve the goals of national health security and fostering new growth industries. Therefore, it is inevitable to study information services based on the classification system and classification model for establishing a national collaborative R&D strategy. Seven classification - Diagnosis_biomarker, Drug_discovery, Epidemiology, Evaluation_validation, Mechanism_signaling pathway, Prediction, and Vaccine_therapeutic antibody - systems were derived through reviewing infectious diseases-related national-funded research projects of South Korea. A classification system model was trained by combining Scopus data with a bidirectional RNN model. The classification performance of the final model secured robustness with an accuracy of over 90%. In order to conduct the empirical study, an infectious disease classification system was applied to the coronavirus-related research and development projects of major countries such as the STAR Metrics (National Institutes of Health) and NSF (National Science Foundation) of the United States(US), the CORDIS (Community Research & Development Information Service)of the European Union(EU), and the KAKEN (Database of Grants-in-Aid for Scientific Research) of Japan. It can be seen that the research and development trends of infectious diseases (coronavirus) in major countries are mostly concentrated in the prediction that deals with predicting success for clinical trials at the new drug development stage or predicting toxicity that causes side effects. The intriguing result is that for all of these nations, the portion of national investment in the vaccine_therapeutic antibody, which is recognized as an area of research and development aimed at the development of vaccines and treatments, was also very small (5.1%). It indirectly explained the reason of the poor development of vaccines and treatments. Based on the result of examining the investment status of coronavirus-related research projects through comparative analysis by country, it was found that the US and Japan are relatively evenly investing in all infectious diseases-related research areas, while Europe has relatively large investments in specific research areas such as diagnosis_biomarker. Moreover, the information on major coronavirus-related research organizations in major countries was provided by the classification system, thereby allowing establishing an international collaborative R&D projects.
