Postulating that academic papers can positively impact the actual teaching practices of science teachers, this study analysed the process of understanding and utilising academic papers by science teachers to teach scientific creativity in their schools. The 45--hour graduate course of three science teachers was explored to identify the difficulties teachers encountered in trying to understand academic papers and to discover how to solve these difficulties. Second, which aspects should be considered when developing teaching materials for scientific creativity to be used in schools were analysed. A transformation model of an academic paper was proposed to understand this process, and the results were organised accordingly. According to this model, it was emphasized to translate academic papers from a general and abstract state to a local and concrete state. Therefore, the role of science educators as knowledge translators was discussed for more practical and effective use of academic papers in school. This study is expected to contribute to research-based teaching by linking academic research with teaching practice.

To transform tall goldenrods, which are invasive alien plant that destroy the ecosystem of South Korea, into useful materials, cellulose fibers isolated from tall goldenrods are applied as EMI shielding materials in this study. The obtained cellulose fibers were blended with CNTs, which were used as additives, to improve the electrical conductivity. TGCF/CNT papers prepared using a facile paper manufacturing process with various weight percent ratios and thickness were carbonized at high temperatures and investigated as EMI shielding materials. The increase in the carbonization temperature, thickness, and CNT content enhanced the electrical conductivity and EMI SE of TGCF/CNT carbon papers. TGCF/CNT-15 papers, with approximately 4.5 mm of thickness, carbonized at 1300 °C exhibited the highest electrical conductivity of 6.35 S cm−1, indicating an EMI SE of approximately 62 dB at 1.6 GHz of the low frequency band. Additionally, the obtained TGCF/CNT carbon papers were flexible and could be bent and wound without breaking. [ABSTRACT FROM AUTHOR]

This paper analyses carbon emissions and value-added embodied in trade between two large developed countries, South Korea and the United States, during 2000-2014. Using multi-regional input-output (MRIO) tables, our analysis reveals that carbon emissions and value-added embodied in exports grew by 19% and 101% for South Korea but shrank by 43% and 7% for the United States. As a result, South Korea experienced a 40% increase in net carbon exports and 243% increase in net valueadded exports. At the industry level, the primary drivers of changes in carbon exports were electricity and basic materials. The majority of industries in witnessed improvements in carbon intensities suggesting improved environmental efficiency. While both countries achieved a decoupling of carbon emissions from value-added exports, substantial year-to-year and sectoral variations were observed. Finally, structural decomposition analysis indicates that domestic supply-side factors played a role in decreasing emissions whereas foreign demand-side factors contributed to emissions increases. In line with the main findings, various implications for policy and future research are discussed. [ABSTRACT FROM AUTHOR]

This study applied various scientific analyses to one fragment of paper and three pigments excavated from earthenware found in the Hoeamsa Temple site at Yangju, Korea, which is believed to have been built in the early twelfth century. Radiocarbon dating of the paper fragment suggests a manufacture date between 1460 and 1646 (at a 95% confidence interval). It was estimated to have been used during the early and middle period of the Joseon dynasty (1391–1776), when the Hoeamsa Temple site was rebuilt. In addition, by staining the fiber of the paper fragment with Graff "C" stain, the paper's raw material was identified as paper mulberry through dislocation, cross-marking, and transparent membrane, which are characteristics of the bast fiber. Efforts were made to identify their material properties and manufacturing techniques of the three types of pigments. Color difference analysis was performed by distributing the pigments in large areas to reveal characteristic differences according to the color difference of the pigment. We found that green-type pigments are malachite and atacamite, red-type pigments are hematite based on the element Fe, and white-type pigments are quartz and muscovite based on the elements Si and Al. In addition, as the size distribution of the three types of pigments is wide and has a multi-peak distribution curve, it was concluded that the pigments were used without purification.

In this study, four novel bacterial strains, USB13T, AW1T, GTP1T, and HM2T, were isolated from various environments in Busan and Jeju Island, Republic of Korea. The 16S rRNA sequencing results indicated that the four novel strains belong to the genus Ramlibacter. All four strains were tested for their potential cellulolytic properties, where strain USB13T was identified as the only novel bacterium and the first within its genus to show cellulolytic activity. When tested, the highest activities of endoglucanase, exoglucanase, β-glucosidase, and filter paper cellulase (FPCase) were 1.91 IU/mL, 1.77 IU/mL, 0.76 IU/mL, and 1.12 IU/mL, respectively at pH 6.0. Comparisons of draft whole genome sequences (WGS) were also made using average nucleotide identity, digital DNA-DNA hybridization values, and average amino acid identity values, while whole genome comparison was visualized using the BLAST Ring Image Generator. The G + C contents of the strains ranged from 67.9 to 69.9%, while genome sizes ranged from 4.31 to 6.15 Mbp. Based on polyphasic evidence, the novel strains represent four new species within the genus Ramlibacter, for which the names Ramlibacter cellulosilyticus sp. nov. (type strain, USB13T = KACC 21656T = NBRC 114839T) Ramlibacter aurantiacus sp. nov. (type strain, AW1T = KACC 21544T = NBRC 114862T), Ramlibacter albus sp. nov. (type strain, GTP1T = KACC 21702T = NBRC 114488T), and Ramlibacter pallidus sp. nov. (type strain, HM2T = KCTC 82557T = NBRC 114489T) are proposed. [ABSTRACT FROM AUTHOR]

Factors of graphomotor skills may serve as indicators to determine a writer's handwriting proficiency or acclimation to different writing surface textures. This study examines differences in children's graphomotor skills based on types of writing medium and gender. Participants were 97 six-year-old Korean preschool children who had not received formal writing training prior to the study. Writing tasks were completed on a tablet screen and paper. Writing samples were analyzed using the Eye and Pen software to investigate spatial, temporal, and pressure exertion exhibited during the writing tasks. A repeated measures ANOVA revealed differences in graphomotor skills such as print size, writing speed, and writing pressure. Writing on a tablet screen decreased clarity of writing; print size and speed increased as the stylus slides across the tablet surface with relatively less friction, thereby decreasing the exertion of writing pressure. Analysis of writing differences according to gender indicated that boys generated larger print sizes than girls. Results suggest that while simple writing tasks may be feasible on the tablet screen, providing children with a larger writing medium and encouraging larger print sizes for writing practice, especially for boys, may be beneficial in the development of graphomotor skills among young learners.

This corpus-driven longitudinal study investigates the structural use of lexical bundles in published research article (RA) introductions in applied linguistics written by English experts and Korean graduate students across two different levels of study. Frequency-based bundles were retrieved from a corpus of 200 published RA introductions and two corpora of 46 and 49 introductions of term papers written at two time points of the first and fourth semester of graduate course. In a further step, the structures of the bundles in different rhetorical moves of RA introductions were analyzed to reveal the developmental patterns in bundle use. The analyses show that the Korean graduate students are in the developmental process of academic writing featured by a shift from clausal style to phrasal style as their academic level advances. The results also suggest that the students have difficulty in appropriate bundle use in specific rhetorical moves even at the later academic level of graduate coursework. The pedagogical implications of L2 students' developmental order are discussed.

Background The purpose of our study was to analyze scientific papers published by South Korean plastic surgeons in journals included in the Science Citation Index Expanded (SCIE), and to evaluate the publication and research activities of Korean plastic surgeon. Methods We conducted a survey of SCIE papers in the field of plastic surgery published by South Korean authors between 2001 and 2010 using Web of Science software. We further analyzed these results according to the number of publications per year, journals, institution, and type of papers. We also compared the total number of citations to published scientific papers. We analyzed the rank of South Korea among other countries in representative journals. Results Overall, 667 papers were published by South Korean authors between 2001 and 2010. The number of publications increased dramatically from 2003 (n=31) to 2010 (n=139). Subsequently, the ten most productive Korean medical colleges were identified. All published papers received 2,311 citations and the citation to paper ratio was 3.49. The rank of Korea among other countries in terms of the number of published papers remained in the top 10 during the recent 10 years. Conclusions Publication output of Korean plastic surgeon over the last 10 years showed a remarkable growth in terms of quantity and quality. Currently, Korea is among the top six countries in representative plastic surgery journals. Korean plastic surgeons have played a central role in this progress, and it is anticipated that they will continue to do so in the future. [ABSTRACT FROM AUTHOR]

Purpose: This study aimed to analyze interventions for bereaved families and evaluate their effectiveness, with the ultimate goal of supporting evidence-based nursing for bereaved families. Methods: Research trends were identified based on a search of domestic databases from January 2000 to December 2022, and a meta-analysis was conducted on interventions for bereaved families. Forty-five papers were selected, and information was extracted on participants, research design, and interventions. A meta-analysis of seven papers was performed, and the effect size was calculated. Results: Fourteen papers dealt with interventions for middle-aged women who had lost their spouses, 20 used qualitative research methods, and 20 were on art therapy programs. Thirty studies had fewer than 10 participants, and most interventions had 60~120 minutes per session and 9~16 sessions in total. There were seven randomized controlled trials, and all studies included in the quality evaluation showed a low risk of bias. Four papers measured grief as an outcome, and the effect size was -1.9577 (95% CI: -2.9206 to -0.9947), indicating that the treatment significantly decreased grief (P＜0.001). Six papers measured depression as an outcome, and the effect size was -1.6775 (95% CI: -2.1835 to -1.1716), showing that the treatment significantly decreased depression (P＜0.001). Conclusion: Intervention programs for bereaved families were shown to be effective in relieving grief and depression. However, programs should be developed that target middle-aged men who have lost their spouses and children who have lost their parents. Randomized controlled trials should also be conducted on interventions to reduce grief and depression. [ABSTRACT FROM AUTHOR]

Purpose: To describe the present status and changing patterns of medical papers related to keywords of vaccine and vaccination published in Korea over the last 50 years, and provide basic data for future studies. Materials and Methods: 185,603 papers are registered in the medical database KoreaMed, which is run by Korean Association of Medical Journal Editors. Among these papers, a search with the keywords vaccine or vaccination revealed a total of 1,089 articles which were published on vaccine and/or vaccination during the period of September 2, 1962 to April 30, 2012. Our study endeavors to analyze these 1,089 articles. Results: Only one article published with the keywords vaccine and/or vaccination was published in the 1960s, and the number of journals steadily increased starting from the 1970s (24 articles) to 2 times, 10 times, 20 times in the 1980s, 1990s, and the 2000s (585 articles), respectively. The articles were classified into reviews (20.2%), original articles with clinical study (40.7%), original articles with experimental study (24.6%), and case reports (8.2%). The review articles mainly dealt with an overview. The original articles with clinical study were on epidemiology, effect and immunogenicity, clinical trial. Original articles with experimental study were mainly comprised of complication and overview. Articles on vaccine, pathogen or disease topics were mostly microorganisms such as bacteria or viruses, and studies on anti-cancer vaccines or vaccines of specific diseases were sparse. Conclusion: The above data reflects the clinical uses of vaccines in Korea and the history of vaccine studies. The number of vaccine-related articles is increasing rapidly since the first article was published in 1962. This implies that with the increase of studies of clinical trials, clinical uses and results and analyses of the results, articles relating to basic studies are also on the rise. We intend these findings to be of use to researchers in this... [ABSTRACT FROM AUTHOR]

The current situation of South Korean democracy displays severe partisan conflicts between two major factions around political reformation of the judiciary department and the ensuing social issues of justice and fairness. In this light, this article examines the problematic relationship of democracy, faction and diversity revealed in The Federalist Papers. I argue that Publius' thinking in The Federalist Papers discloses the existential ground of democratic republic which embraces both the constant emergence of factious struggle and the political necessity of social diversification. Some scholarly views of The Federalist Papers merely focus on the economic aspects of Publius' attempt to regulate the factional strife concerning property rights; other studies maintain that Publus' constitutional scheme simply provides a formalistic basis for the institutional compromise of the clashing interests. But a close reading of The Federalist Papers reveals the Publius' concern of faction is to deal with a deeper ground of political existence that cannot escape the differing movements of human passions, interests and opinions in everyday life. Furthermore, Publius' constitutional design of the extended republic and the separation of powers ultimately discloses the political necessity of social diversification to sustain the self-ruling power of popular government facing the clashing movements of human differentiation. Thereby, this article suggests that the Publius' political insights of the nature of popular regime help us to carefully approach the recurrent problem of democratic factions in the Republic of Korea.

Generalized anxiety disorder (GAD) can cause significant socioeconomic burden and daily life dysfunction; hence, therapeutic intervention through early detection is important. This study was the final stage of a 3-year anxiety screening tool development project that evaluated the psychometric properties and diagnostic screening utility of the Mental Health Screening Tool for Anxiety Disorders (MHS: A), which measures GAD. A total of 527 Koreans completed online and offline (i.e., paper-and pencil) versions of the MHS: A, Beck Anxiety Inventory (BAI), Generalized Anxiety Disorder-7 (GAD-7), and Penn State Worry Questionnaire (PSWQ). The participants had an average age of 38.6 years and included 340 (64.5%) females. Participants were also administered the Mini-International Neuropsychiatric Interview (MINI). Internal consistency, convergent/criterion validity, item characteristics, and test information were assessed based on the item response theory (IRT), and a factor analysis and cut-off score analyses were conducted. The MHS: A had good internal consistency and good convergent validity with other anxiety scales. The two versions (online/offline) of the MHS: A were nearly identical (r = 0.908). It had a one-factor structure and showed better diagnostic accuracy (online/offline: sensitivity = 0.98/0.90, specificity = 0.80/0.83) for GAD detection than the GAD-7 and BAI. The IRT analysis indicated that the MHS: A was most informative as a screening tool for GAD. The MHS: A can serve as a clinically useful screening tool for GAD in Korea. Furthermore, it can be administered both online and offline and can be flexibly used as a brief mental health screener, especially with the current rise in telehealth. [ABSTRACT FROM AUTHOR]

In South Korea, the rapid proliferation of smartphones has led to an uptick in messenger phishing attacks associated with electronic communication financial scams. In response to this, various phishing detection algorithms have been proposed. However, collecting messenger phishing data poses challenges due to concerns about its potential use in criminal activities. Consequently, a Korean phishing dataset can be composed of imbalanced data, where the number of general messages might outnumber the phishing ones. This class imbalance problem and data scarcity can lead to overfitting issues, making it difficult to achieve high performance. To solve this problem, this paper proposes a phishing messages classification method using Biased Discriminant Analysis without resorting to data augmentation techniques. In this paper, by optimizing the parameters for BDA, we achieved exceptionally high performances in the phishing messages classification experiment, with 95.45% for Recall and 96.85% for the BA metric. Moreover, when compared with other algorithms, the proposed method demonstrated robustness against overfitting due to the class imbalance problem and exhibited minimal performance disparity between training and testing datasets.

In existing research, the analysis of the cause of marriage delay has been focused on the educational level. Marriage influences the housing price because it increases housing demand. Also, it has greatly influenced the labor market participation of women. Marriage delay is the major factor of birthrate decrease because it decreases the child-bearing period and the possibility of childbearing in women. Finally, it is the major factor of the rate of decrease of the population and of economic growth. In this paper, we discuss the economic capacity as well as the educational level for the exact cause analysis. The purpose of this paper is cause analysis for marriage delay of singles in South Korea. We expect this research to propose new values for the government policy-making on marriage and birthrates through analysis of reasons for the delay in marriage. In this paper, we used the Korea Labor & Income Panel data (2004-2014). The survey was conducted among 500 men and women aged 20 to 40 through a marital status check for the last 10 years. In this study, we used estimation method and non-parametric statistics. In this paper, independent variables are the age, number of siblings, the metropolis residence, the economic level of family, the education level, the income, and the employment status. The dependent variable is the delay of marriage. Marriage encouragement is needed for birthrate increase. Also, analysis of the cause of the marriage delay of singles is essential for government policy-making. In this research, the sociocultural effect, the educational level, the economic capacity have been considered for the analysis of the cause of marriage delay. Also, we discussed the economic capacity as well as the educational level for the exact cause analysis. [ABSTRACT FROM AUTHOR]

For the last several decades, people around the world have become increasingly interested in Korean economy and society. Along with this demand factor, the supply factor, that is, the eagerness of Korean scholars to actively interact with global academia, has encouraged Korean scholars to write more articles about the Korean economy in English. The combination of these two factors has over the last two to three decades resulted in the growth of English-language papers dealing with Korean subjects. However, the increase in English-language papers examining Korean subjects over the last two decades is largely explained by the overall growth of English-language papers in general, while the ratio of Korean-related subjects among those English-language publications has actually declined. More analyses should be made to understand this pattern. However, if we consider policy measures to improve the situation, it is reasonable first to think about how to enhance the availability or quality of data used for research on Korea. Even without allocating more money, the Korean government can attract scholars to study Korean subjects by making existing government data more available to scholars. Since the government is the largest data holder, a more forward-looking approach by the government can attract more scholars to study Korean subjects and to write more papers in English.

The aim of this study is to investigate the future research direction by utilizing keyword network analysis to analyze topics related to resilience in young children. For this purpose, among the journal papers listed in the Korean Journal Citation Index from 2002 to 2023. The keywords from these papers were extracted, and in-degree and out-degree centrality, betweenness centrality, and networks sociogram were analyzed through keyword network analysis. The findings of this study are as follows: Firstly, in Korean research on resilience of young children, resilience was expressed using eight different terms, and diverse sub-elements were observed accordingly. Secondly, keywords such as selfresilience, which encompasses sub-elements like autonomy, self-control, attachment, concerned behavior, recovery resilience, and resilience, which encompasses sub-elements like resilient competence, relational resilience, and emotional resilience, emerged as important in the analysis. Additionally, crucial keywords associated with young children's resilience included externalizing problem behavior, teacher-child conflict, teacher-child intimacy, pro-sociality, flow, emotion regulation, happiness, playfulness, mothers' parenting efficacy, adjustment to ECEC centers, gender of children, psychological health, and peer interaction. Through this study, we have identified and discussed the key topics related to the resilience of young children, explored the variables influencing their resilience, and examined strategies for enhancing their resilience.

This paper compares how educational reform documents in Korea and the U.S.A. conceptualize teachers and teacher education and examines how, if at all, the discourses of one country appear to influence those of the other. Special attention is paid to the ways in which reform documents incorporate different conceptions of professionalism in framing and in proposing remedies for the problems with teachers and teacher education. Eighteen reform documents issued in the two countries by national governmental and non-governmental organizations since the 1980s were selected and analyzed. It was found that while both Korean and American documents seem to draw on elements of the functionalist (or trait theory) conception of professionalism, Korean documents put more emphasis on issues related to the power/autonomy of teachers. Regarding cross-country influence, Korea seems to have appropriated ideas and moved toward the structures and practices evidenced in the U.S.A. during an earlier period.
