The purpose of this study is to examine the unique characteristics of the Korean academic system with regard to brain circulation, with a specific emphasis on the influence of overseas-trained academics on research activities within the Korean academic system. We have analyzed the statistical data on individual characteristics and performances of 48,499 Korean academics in science and engineering. We have examined the results at both the system and individual levels within the broader context of the macro characteristics of the Korean academic system. Our analysis reveals that the total number of domestically-trained academics exceeds the number of overseas-trained academics. However, in terms of research funding, overseas-trained academics tend to receive more funding than domestically-trained academics. Furthermore, after controlling other factors such as funding, personal attributes, and environmental factors, our analysis demonstrates that overseas training has a significant and favorable impact on the publication of internationally renowned journals. As such, the presence of overseas returnees has been essential for the effective functioning of the Korean academic system in the global research network and for conducting high-quality academic research. Therefore, the advantages of dependence on scientific core countries such as the US for overseas training have persisted. Nevertheless, upon scrutinizing the group of recently appointed 5,806 academics exclusively, we have discovered that junior academics who received their education domestically exhibit sufficient academic proficiency compared to their colleagues educated overseas. This observation highlights the potential for the Korean academic system to evolve into a self-sustaining system.

A main purpose of this research was to analyze environmental factors to influence helicopter accidents contrary to the fact that the almost 80% of helicopter accidents happened due to pilots' human errors. There have been about 14 helicopter accidents in civil aviation sector last decade. It is noteworthy that nine of 14 accidents happened during the external sling load operation. Moreover, there is no law or regulation which could cover the helicopter external sling load operation or human external cargo in Korea. In this paper, it was analyzed the training and education regulations regarding helicopter external sling load operation or human external cargo in regulations of FAA and EASA, Based on analyzing and comparing the FAR part 133 and domestic aviation law (aviation safety act and flight safety regulations), it was found out the implication how to apply helicopter type rating for external sling load operation and human external cargo operation. To sum up, this paper expect central government should cooperate and amend aviation law which apply external sling load operation and external cargo to establish sound safety culture in Korea.

UPRT(Upset Prevention And Recovery Training) is an accident prevention training program developed over a three-year period after the main cause of aircraft accidents in commercial aviation between 2001 and 2011 was analyzed as LOC-I(Loss Of Control Flight). In 2014, ICAO presented UPRT for fixed-wing aircraft through Doc.10011(Manual On Aeroplane Upset Prevention And Recovery Training) and recommended mandatory implementation to Contracting States from March 2019. Since naval P-3C is a major mission of maritime patrol and anti-submarine warfare, it takes a lot of time to fly at low altitude (70-600 m), and the majority of P-3C pilots have experienced spatial disorientation, so Upset prevention and recovery training is essential for naval P-3C pilots. To this end, this study intends to present measures for UPRT from limited conditions using the P-3C simulator owned by the Navy.

Recently, metaverse technology is being used in various service industries such as games, entertainment, manufacturing, distribution, advertising, and education. Studies on the correlation between the continuous use of devices used in metaverse content are still insufficient. In order to be more immersed in the metaverse, it is necessary to develop a natural movement and an easy-to-use input device. Based on flow, this study was conducted on the topic of continuous use of metaverse contents and devices. The constituent factors of Flow, an independent variable, were set as sense of reality, immersion, and interaction. We intend to use the data of 500 male and female metaverse users for research through a survey institution. Among the flow factors that increase the continuous use of metaverse contents and devices, the factors that have the greatest influence were studied. Through the results of this study, it is intended to help establish the direction of the next-generation metaverse content and device industry.

The purposes of this study are to find the difference in information literacy among the elderly home care service users and to identify the impact of information literacy on service quality and satisfaction among service users. To achieve the goals, this study used 466 responses from the elderly home care service recipients in Jeollabukdo providence, and conducted t-tests, ANOVA and a series of regression analyses. The results showed that there were significant differences in information literacy by gender, household type, residence area, education level and subjective health status among service users. The study also found that service users information literacy had a significant impact on service quality and satisfaction, and it confirms the importance of customized service. This study suggests that information literacy inequality exists among the elderly home care service users, therefore, the way to improve information delivery strategy should be developed for the information-poor elderly.

This paper aims to explore a comparative instructional effects among meaning-based communicative language teaching, input-enhanced FnF instruction and output-enhanced FnF instruction in order to optimize the teaching methods of target grammar and vocabulary. The experiment selected three homogeneous groups of 30 students in each group for the comparison: One comparative group with communicative language teaching, one input-enhanced FnF group and another output-enhanced FnF group. The result indicates that the input-enhanced group outperformed the comparative group in the grammar test with statistical significance and the output-enhanced group overweighted the comparative group in the vocabulary test. However, no significant statistical difference was found between the input-enhanced group and the output-enhanced group. The conclusion from the result could bear the following pedagogical implication: The general English education must use the eclectic method of adopting communicative language teaching with FnF of input-enhanced target grammar and output-enhanced target vocabulary to supplement the students with the basic vocabulary and grammar.

Purpose: The study examined obesity conditions and related factors in middle aged Korean women who had been diagnosed as obese based body mass index (BMI) or waist circumference (WC) measurement. Presently, BMI alone, WC alone, or BMI + WC were used as obesity measures. Methods: Subjects were 488 women 40~64 years of age living in one city, Korea. Structured questionnaires concerning general characteristics, health behavior practices, and chronic disease history were completed by each subject. Results: The proportions of obesity were 42.4% by BMI, 39.3% by WC, and 51.3% by the combination of both measurements. Chi-square test revealed significant associations of obesity with age, education level, menopausal status, frequency of excessive eating, and history of diabetes mellitus or hypertension. These associations were similar for the three measurement schemes. There was significant positive relationship between BMI and WC, whereas the relationship between BMI and WHR (waist-hip ratio) was not significant. Conclusions: The combination of BMI and WC measurement may be a valid way to evaluate the obesity status in middle-aged women. Developing an obesity management program that includes control of excessive eating, and consideration of menopausal status and history of chronic diseases would be prudent.

Productive welfare is a form of welfare policy that helps welfare recipients move beyond being mere objects of support and develop into members who can actively contribute to society and the economy. This aims to improve individual self-reliance, including education, vocational training, and employment support services, ultimately reducing the economic burden on society as a whole and promoting economic growth. By examining whether productive welfare is possible in Korea, this study emphasizes the role and importance of productive welfare as a solution to social and economic problems. The Republic of Korea has experienced various social problems along with rapid economic growth. The entry into an aging society, increased youth unemployment, and widening social gaps have created complex and diverse social welfare needs. In this situation, productive welfare is attracting attention as a method that goes beyond simple financial support and provides a foundation for beneficiaries to become self-reliant. This study seeks to present a new horizon for social welfare policy by examining the possibility of implementing productive welfare in Korea and exploring ways to achieve it.

This study investigated the impact of two distinct MS basal media: one containing FeNaEDTA and the other FeEDDHA, on the growth of five unique gerbera cultivars (Shy Pink, Pink Holic, Breeze, Harmony, Snow Dream). Notably, the response to these media types varied significantly among the cultivars, particularly concerning leaf yellowing and plant growth. 'Shiny Pink' and 'Pink Holic' exhibited leaf yellowing on the FeNaEDTA-containing medium but displayed leaf greening on the FeEDDHA-containing medium. In contrast, 'Snow Dream,' 'Harmony,' and 'Breeze' remained unaffected on both medium types. However, the FeNaEDTA-containing medium promoted higher plant height and petiole length in 'Breeze,' 'Harmony,' and 'Snow Dream' than the FeNaEDTA-containing medium did. A promotive effect of silver nanoparticles (AgNPs) on plant growth and leaf greening was observed in 'Pink Holic,' particularly on the FeNaEDTA-containing medium, while the addition of AgNPs to the FeEDDHA-containing medium negatively affected plant growth. These results highlight the substantial influence of medium type, specifically the presence of FeNaEDTA or FeEDDHA, on gerbera growth responses, emphasizing the critical role of medium selection in gerbera propagation. Additionally, when contemplating the addition of AgNPs for in vitro gerbera propagation, it is crucial to consider the medium type.
