The 21st century of the 4th industrial revolution demands 'competency' as a new educational concept that is different from that required in the industrialization era. In accordance with these changes and demands of society, universities are being called for key competency-based education and innovation in education through this by breaking away from the existing methods in liberal arts and major education. At this point, universities are presenting a comprehensive reform of liberal arts education for various financial support projects. This study presents the case of University C regarding the reform of the liberal arts curriculum for the innovation of liberal arts education in universities. According to the research results, each university is reorganizing the liberal arts curriculum in a way that can suggest various key competencies according to the university's founding philosophy and induce key competencies in the aspect of liberal arts education. For the key competency-based liberal arts curriculum of University C, we proposed various subjects for insufficient key competency subjects, various micro-degrees were proposed to specialize liberal arts education, and meta-learning-related liberal arts subjects were presented to improve basic learning ability of the students.

The restart of scramjet engine is almost impossible in case its unstart happens during engine operation. Therefore, it is essential to prognosticate the scramjet engine unstart phenomena. A numerical simulation of a scramjet engine is conducted to investigate the unstart process of the scramjet engine by adjusting the backpressure at the isolator outlet to the engine analysis environment. The start and unstart of the engine are identified by applying a support vector machine (SVM) through the data measured by wall pressure so that the locations of the pressure sensors most suitable for the unstart detection are selected. And the operation conditions in which the engine is avoid to be unstarted are quantified to perceive the safety margin.

This study is a literature analysis study that analyzed program intervention research papers to understand the characteristics of lifestyle intervention programs to prevent cardiovascular disease. The final 18 papers were selected by applying search terms such as "cardio-cerebrovascular disease" and "intervention" through electronic databases such as Pubmed. As for the criteria for selecting program participants in the study, physiological criteria were mainly used, and there were many programs that mediated physical activity and eating habits. Education was the most widely used intervention type, and there were many studies that combined and applied several interventions. During the intervention period, long-term interventions averaged more than 22 weeks, and biophysical indicators were most frequently used as effect indicators for measuring the intervention effect. Through this study, it is suggested that environmental and social support is needed to develop intervention programs considering the interrelationship of various lifestyle habits and maintain healthy lifestyle habits.

We tested the difference and the relationship in instructional ratings by professors and college students. Subjects were 6 professors and 9 college students participated in teaching competition as a rater. They completed instructional rating forms consisted of 10 criteria for 11 participants according to Lickert Scale. Data were analyzed by independent t-test and Pearson correlation. Results were as follows: ① There was no statistical difference in mean scores between the professor and the student; ② Correlation between professors' and students' evaluations was .78 which is statistically meaningful and high. These results support the notion that students evaluate as reliably as professors. They also imply that pre-service college students can be utilized for teaching practice as meaningful peer evaluators. The findings are meaningful in that instructional ratings of instructors and students were compared in a controlled setting. However, replication studies involving wide range of instructors and students are needed for generalization since the subjects in this study were restricted to pre-service teachers and their instructors.

This paper analyzed the influence of employment, human resource development, and labor practices on the corporate performance. Data were collected from the Korea Labor Institute's workplace panel survey(WPS) from 2017, and the analysis used 2,868 companies. This study employed operating profit as a corporate performance. Employment included open recruitment of new employees, evaluation of NCS job competency, and implementation of core human resources acquisition program. Human resource development consisted of incumbent training, job competency improvement evaluation, management program for low performer, emoloyee's career plan, and HRD using job analysis. Labor practices included guarantees for parental leave, guarantees for maternity leave, and support for childcare facilities. The analysis method used binominal logistic regression analysis for two groups of operating profit surplus and deficit companies. As a result of the analysis, it was possible to confirm the influence of employment, human resource development, and labor practices on performance. And the implications of employment, human resource development, and labor practices to improve corporate performance were discussed.

This study is a descriptive investigative study to correlate of learning flow, self-directedness, self-regulated learning ability and learning achievement of nursing students who in non-face-to-face learning environment. The subjects of the study were 179 nursing college students based in B, G city, who collected data from September to October 2021. The data analysis used the SPSS 24.0 program and performed descriptive statistics and correlation analysis. As a result of the study, the average learning flow was 38.54±7.87 points, self-directedness was 134.83±19.81 points, self-regulated learning ability was 42.93±5.98 points and learning achievement was 15.03±2.56 points. The relationships among learning flow, self-directedness, self-regulated learning ability, and learning achievement showed significant positive correlations. Therefore, strategies to increase the learning achievement of nursing college students in a non-face-to-face environment, and environmental improvement and institutional support to increase learning flow are needed.

Recently, as the amount of data collected by drones has rapidly increased, it is necessary to support cloud computing technology that can securely and efficiently store and process data. However, various security threats such as stealing, leaking, or tampering with data communicated by drones can occur due to attackers. Therefore, there is a need for security technology to provide secure communication of data collected from drones. Among various security technologies, the KP-ABE scheme, which is attribute-based encryption, is a security technology that satisfies two characteristics: data encryption and user access control. This paper researched the KP-ABE scheme and proposed a secure data access control scheme to the drone environment. This proposed scheme provides confidentiality and integrity of data communicated in a drone environment and secure access control and availability. In addition, it provides a fast ciphertext search and constant size ciphertext among the requirements to be provided in the KP-ABE scheme.

The KoreaN Cohort Study for Outcomes in Patients With Chronic Kidney Disease (KNOW-CKD) was launched in 2011 with the support of the Korea Disease Control and Prevention Agency. The study was designed with the aim of exploring the various clinical features and characteristics of chronic kidney disease (CKD) in Koreans, and elucidating the risk factors for CKD progression and adverse outcomes of CKD. For the cohort study, nephrologists at 9 tertiary university-affiliated hospitals participated in patient recruitment and follow-up. Biostatisticians and epidemiologists also participated in the basic design and structuring of the study. From 2011 until 2016, the KNOW-CKD Phase I recruited 2238 adult patients with CKD from stages G1 to G5, who were not receiving renal replacement therapy. The KNOW-CKD Phase II recruitment was started in 2019, with an enrollment target of 1500 subjects, focused on diabetic nephropathy and hypertensive kidney diseases in patients with reduced kidney function who are presumed to be at a higher risk of adverse outcomes. As of 2021, the KNOW-CKD investigators have published articles in the fields of socioeconomics, quality of life, nutrition, physical activity, renal progression, cardiovascular disease and outcomes, anemia, mineral bone disease, serum and urine biomarkers, and international and inter-ethnic comparisons. The KNOW-CKD researchers will elaborate a prediction model for various outcomes of CKD such as the development of end-stage kidney disease, major adverse cardiovascular events, and death.

Through the 2014 Donbas conflict and the 2022 Ukraine-Russia war, we are experiencing that the command of the air is no longer only secured by the Air Force. Long-range surveillance reconnaissance and strikes carried out by the Air Force could be replaced by drones and missiles, and the enemy's aerial attacks could be controlled by air defense systems such as Panchir and portable anti-aircraft missiles, allowing ground forces to carry out maneuvers freely. In other words, it is much more advantageous for the air force and the navy to take control of the air through long-distance operations, and the ground forces should support them. Therefore, this study aims to consider the cost-effectiveness aspect of the delivery command of the air; it provides implications for quickly responding to enemy air attacks by developing the air defense weapon system, drones, missiles, precision-guided munitions, etc rather than focusing on expensive fighter jets.
