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 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.

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]

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.

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]

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.

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]

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]

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.

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.

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]

Purpose: This study analyzed research trends in infant and toddler rearing behavior among family caregivers over a 10-year period (2010-2021). Methods: Text network analysis and topic modeling were employed on data collected from relevant papers, following the extraction and refinement of semantic morphemes. A semantic-centered network was constructed by extracting words from 2,613 English-language abstracts. Data analysis was performed using NetMiner 4.5.0. Results: Frequency analysis, degree centrality, and eigenvector centrality all revealed the terms ''scale," ''program," and ''education" among the top 10 keywords associated with infant and toddler rearing behaviors among family caregivers. The keywords extracted from the analysis were divided into two clusters through cohesion analysis. Additionally, they were classified into two topic groups using topic modeling: "program and evaluation" (64.37%) and "caregivers' role and competency in child development" (35.63%). Conclusion: The roles and competencies of family caregivers are essential for the development of infants and toddlers. Intervention programs and evaluations are necessary to improve rearing behaviors. Future research should determine the role of nurses in supporting family caregivers. Additionally, it should facilitate the development of nursing strategies and intervention programs to promote positive rearing practices. [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.

Problem solving in real life is a core competency commonly adopted in several subjects recently. The real-world problems were rarely resolved with only one domain of knowledge. Thus, convergence education is becoming a trend in many countries. As on-line education is revitalized because of COVID-19, the need for changes to STEAM education is emerging. In December 2019, the on-line education systems quickly settled in schools because of COVID-19. During the first semester of 2020, most school education was conducted as virtual/distance learning classes. It is necessary to analyze how much technology has been used in the STEAM classes in Korea. This paper analyzes the research papers related to the STEAM education in Korea conducted in the last 10 years. By doing this, we analyze what kind of edutechs we were interested in, what kind of STEAM education actually occurred, and to whom it was conducted. The previous research papers analyzed in this paper are the papers in the Korea Citation Index accredited journals and candidate journals. Finally, this paper proposes educational changing factors to be considered for future technologybased STEAM education. [ABSTRACT FROM AUTHOR]

There are many potential sources of bias in the radar rainfall estimation process. This study classified the biases from the rainfall estimation process into the reflectivity measurement bias and QPE model bias and also conducted the bias correction methods to improve the accuracy of the Radar-AWS Rainrate (RAR) calculation system operated by the Korea Meteorological Administration (KMA). For the Z bias correction, this study utilized the bias correction algorithm for the reflectivity. The concept of this algorithm is that the reflectivity of target single-pol radars is corrected based on the reference dual-pol radar corrected in the hardware and software bias. This study, and then, dealt with two post-process methods, the Mean Field Bias Correction (MFBC) method and the Local Gauge Correction method (LGC), to correct rainfall-bias. The Z bias and rainfall-bias correction methods were applied to the RAR system. The accuracy of the RAR system improved after correcting Z bias. For rainfall types, although the accuracy of Changma front and local torrential cases was slightly improved without the Z bias correction, especially, the accuracy of typhoon cases got worse than existing results. As a result of the rainfall-bias correction, the accuracy of the RAR system performed Z bias_LGC was especially superior to the MFBC method because the different rainfall biases were applied to each grid rainfall amount in the LGC method. For rainfall types, Results of the Z bias_LGC showed that rainfall estimates for all types was more accurate than only the Z bias and, especially, outcomes in typhoon cases was vastly superior to the others.

Leveraging data on organizational social distancing initiatives (SDIs) this paper examines the link between SDI implementation and perceived organizational support (POS). The paper discusses and tests the intended beneficiary heuristic to help explain why and when employment practices may induce POS. We suggest that SDIs, involving various ways to separate employees to keep them safe, have the important secondary benefit of increasing employees' perception that the organization cares about their well-being and values their contributions. Using the intended beneficiary heuristic we argue that such favorable treatment as SDIs relates positively to POS most when employees attribute their implementation to the organization's concern for the welfare of employees. Results of two studies, a cross-sectional study with 121 employees in the United States and a longitudinal study with 103 employees in South Korea, indicate that SDIs were positively associated with employees' POS, which in turn improved their job satisfaction (Studies 1 and 2), affective organizational commitment, and organizational citizenship behavior (Study 2). The results also show that these relationships were stronger when employees perceived SDIs to be implemented to protect their welfare rather than as a means of protecting the organization.

Objective: The aim of this study was to verify the equivalence and effectiveness of the tablet-administered Korean Repeatable Battery for the Assessment of Neuropsychological Status (K-RBANS) for the prevention and early detection of dementia. Methods: Data from 88 psychiatry and neurology patient samples were examined to evaluate the equivalence between tablet and paper administrations of the K-RBANS using a non-randomly equivalent group design. We calculated the prediction scores of the tablet-administered K-RBANS based on demographics and covariate-test scores for focal tests using norm samples and tested format effects. In addition, we compared the receiver operating characteristic curves to confirm the effectiveness of the K-RBANS for preventing and detecting dementia. Results: In the analysis of raw scores, line orientation showed a significant difference (t=-2.94, p<0.001), and subtests showed small to large effect sizes (0.04-0.86) between paper- and tablet-administered K-RBANS. To investigate the format effect, we compared the predicted scaled scores of the tablet sample to the scaled scores of the norm sample. Consequently, a small effect size (d≤0.20) was observed in most of the subtests, except word list and story recall, which showed a medium effect size (d=0.21), while picture naming and subtests of delayed memory showed significant differences in the one-sample t-test. In addition, the area under the curve of the total scale index (TSI) (0.827; 95% confidence interval, 0.738-0.916) was higher than that of the five indices, ranging from 0.688 to 0.820. The sensitivity and specificity of TSI were 80% and 76%, respectively. Conclusion: The overall results of this study suggest that the tablet-administered K-RBANS showed significant equivalence to the norm sample, although some subtests showed format effects, and it may be used as a valid tool for the brief screening of patients with neuropsychological disorders in Korea.

The present study represents both a case study about microbial degradation by microorganisms that can cause damage to old manuscripts as well as health threats to the librarians. Most of the microbiological damage started in poor environmental conditions of storage and display. The study aims to characterize the microbes that cause microbial deterioration of the historical books. Microbial swabs were taken from the manuscript under study, and the isolated organisms were identified using the sequencing of rRNA of the ITS region of the rDNA gene at Solgent company, South Korea. The results showed three bacterial species: Micrococcus luteus (MH450098), Microbacterium schleiferi (NR044936T) and Bacillus subtilis (NR1126 29T), as well as: two fungal species Aspergillus ustus (NR134245T) and Aspergillus chevalieri (NR135340T). The genus Aspergillus ustus was the dominant genus isolates. It was followed by Aspergillus chevalieri. The biological activities of the isolated microorganisms were studied and showed the highest activities cellulolytic and proteolytic activities observed by Aspergillus chevalieri. Modern devices were used to study the infected and the uninfected parts of the same manuscript by taking some of the falling pieces from the manuscript, such as (light microscopes, SEM with EDXS, and FTIR). Surface observation obtained by light microscopy showed microbial infiltration on infected paper, significant changes detected by SEM in some elements decreased the percentage, and the other element percentage increased. Moreover the other elements disappeared. The chemical changes inside the paper structure resulted from the degradation of large organic compounds (chemical functional groups) by the action of extra-cellular enzymes secreted by deteriorating fungal species, converting these compounds into smaller ones using the FTIR.

Articles from open access and local journals are important resources for research in Korea and the usage trends of these articles are important indicators for the assessment of the current research practice. We analyzed an institutional collection of published papers from 1998 to 2014 authored by researchers from Seoul National University, and their references from papers published between 1998 and 2011. The published papers were collected from Web of Science or Scopus and were analyzed according to the proportion of articles from open access journals. Their cited references from published papers in Web of Science were analyzed according to the proportion of local (South Korean) or open access journals. The proportion of open access papers was relatively stable until 2006 (2.5 ~ 5.2% in Web of Science and 2.7 ~ 4.2% in Scopus), but then increased to 15.9% (Web of Science) or 18.5% (Scopus) in 2014. We analyzed 2,750,485 cited references from 52,295 published papers. We found that the overall proportion of cited articles from local journals was 1.8% and that for open access journals was 3.0%. Citations of open access articles have increased since 2006 to 4.1% in 2011, although the increase in open access article citations was less than for open access publications. The proportion of citations from local journals was even lower. We think that the publishing / citing mismatch is a term to describe this difference, which is an issue at Seoul National University, where the number of published papers at open access or local journals is increasing but the number of citations is not. The cause of this discrepancy is multi-factorial but the governmental / institutional policies, social / cultural issues and authors' citing behaviors will explain the mismatch. However, additional measures are also necessary, such as the development of an institutional citation database and improved search capabilities with respect to local and open access documents.

To prevent regulation from becoming an obstacle to healthcare technological innovation, regulation should evolve as new healthcare technologies are developed. Although regulation is closely related to healthcare technology development, there are few studies that view healthcare technological advances from the multi-layered perspective of papers, patents, and clinical research and link this with regulatory evolution. Therefore, this study tried to develop a new method from a multi-layer perspective and draw regulatory implications based on it. This study applied this method to intraocular lens (IOLs) for cataract treatment and detected four major healthcare technologies and two recent healthcare technologies. Moreover, it discussed how current regulations evaluate these technologies. The findings provide implications for healthcare technological advances and the evolutionary direction of regulation through the example of IOLs for cataract treatment. This study contributes to the development of theoretical methods for co-evolution with regulations based on healthcare technology innovation. [ABSTRACT FROM AUTHOR]

Background/Objectives: This study identifies the key factors that enhance medical service by analyzing keywords of 761 papers registered in the Research Information Sharing Service(RISS) until 2019 in South Korea. Methods/Statistical analysis: Web crawling was performed based on Python to collect academic papers whose title or keywords include "medical service" among papers registered in RISS. Also, text mining, social network analysis, centrality analysis, and topic modeling were applied as big data analysis methods, and R 4.0.2, UCINET 6.7, and NetDraw 2.172 were used as software for analysis. Findings: Among the 3,175 keywords obtained as a result of text mining, keywords such as "Medical service", "Customer satisfaction", "Medical service quality", "Reuse intention", "Healthcare service", "Medical service value", "Medical tourism", "Emergency medical service", "Medical service use", "Loyalty", "Reliability", and "Telemedicine" were obtained at a high frequency of occurrence. A social network was derived based on 40 core keywords obtained from text mining, and there was a strong connection between "Customer satisfaction - Medical service quality", "Medical service - Customer satisfaction", "Customer satisfaction - Reuse intention", "Medical value quality - Reuse intention", "Customer satisfaction - Medical service value". Five topics such as "Reuse and recommendation intention", "Telemedicine & u-Healthcare", "Medical service accessibility", "Satisfaction management", and "Medical tourism" were obtained as critical topics representing the obtained keywords. The topic "Reuse and recommendation intention" with the highest proportion among the five topics indicates that there is a high quality of the relationship between the consumer and service provider when the consumers are delighted and confident in the service provider's service. Improvements/Applications: Based on the big data analysis method, the key factors of medical service improvement and the relationship between factors were presented. It can be used as fundamental data in attempts to enhance medical services. [ABSTRACT FROM AUTHOR]

The new regulation was introduced to the franchise market of South Korea in that an applicant who wants to be a franchiser must set up direct retail stores and run them for at least one year before recruiting franchisees. Considering the purpose of the regulation, it is inferred that once franchisers run their own stores, their franchisees would be better off than otherwise. This paper addresses one reason that the Korea Fair Trade Commission has no choice but to introduce the regulation. Along the line, this paper investigates whether franchisees would have a more likelihood to make profit in case of franchisers operating their own stores. The result demonstrates that this case could be true since the operation of franchiser-owned stores could be helpful in reducing the cost of franchisees. [ABSTRACT FROM AUTHOR]

Purpose: This study aimed to clarify the concept of pediatric hospice and palliative care through conceptual analysis. It also sought to identify the differences between related concepts such as pediatric death care and pediatric spiritual care, in order to provide foundational data for the development of nursing theory and knowledge. Methods: A conceptual analysis of pediatric hospice and palliative care was conducted using Rodgers’ evolutionary method. Out of 5,013 papers identified, 28 were selected for detailed reading and analysis. Results: Pediatric hospice and palliative care encompasses physical, psychological, social, mental, spiritual, and family care for children with acute and chronic diseases with uncertain prognoses ahead of death, as well as their families. Effective pediatric hospice and palliative care will require multidisciplinary team nursing, effective communication, and supportive policies. Conclusion: The findings of this study suggest that providing pediatric hospice and palliative care will lead to improvements in pain relief for children and families, the efficiency of responses to death in children, and the quality of life for children and families. The significance of this study is that it clearly clarifies the concept by analyzing pediatric hospice and palliative care using an evolutionary method. [ABSTRACT FROM AUTHOR]

The relationship between natural cycles and human actions in causing climate change and its impacts on society have been a subject of debate. This paper explores the responses of pre-modern Koreans to climate change and natural disasters. The focus of this paper is on the societal reactions to these natural calamities and disasters during the Koryŏ dynasty (936–1392 A.D.) and their influence on Korea afterwards. This paper investigates the reasons behind the retention of primal religious worldviews in the face of ecological crises while other major imported religions were abandoned. The research method involved in this paper is archival research, and the literature sources include ancient records and other ecotheological resources. Through an analysis of the archival research and ecotheological resources, this study sheds light on the interpretation of climatic events in pre-modern Korea. Furthermore, based on the research findings, it presents missional implications for the Korean church in the post-pandemic era. This study underscores the importance of the church's responses to environmental awareness, collective responsibility, and spiritual support in addressing the challenges of climate change and provides missional implications for the Korean Church in response to the post-COVID-19 era based on the results of the research.

Christianity does not have as long of a history as other monotheistic religions and traditional ideologies in Korea, but—especially from the end of the 19th century—its new concepts have had a huge impact on the basic thoughts of Korean society. This paper focuses on the effects of Christianity and the activity of Christian communities on women's lives. According to my preliminary findings, in the late 1800s, the Christian missionaries and their newly formed communities offered opportunities for girls and women to get education, a profession, access to better health care, and learn self-care. After the complicated decades between 1910 and 1950, South Korea was experiencing remarkable changes, and Christians were an active part of this rebuilding, helping the lives of those who were struggling with poverty, lack of daily necessities, education, and health care. This paper aims to examine the thoughts and actions of Korean Christian communities towards decisions on childbirth, children out of wedlock, adoption, and single motherhood. This study investigates the approaches of South Korean Christian communities towards women related to the above-mentioned circumstances, focusing on the early examples and the last five to six decades. It is assumed that even though South Korea is now considered a modernized country, the government sometimes fails to cope with current problems, and traditional notions are still strong in familial matters. Therefore, not obeying conventional forms may cause social conflicts, or the decisions are hidden because of taboos and stigmas. This research is based on the publications of Christian communities and involves documentaries and case studies, including the baby box operation and adoption. This paper contributes to the expanding studies on Korean Christian communities, highlighting the social norms and their changes generated by new religious thoughts, while giving an insight into the daily struggles of Korean women's lives when it comes to decision-making about their motherhood.

The relationship between modernization and religion is contested, with the literature differing in how and in what ways religion helps or hinders countries' social, economic, and political development. This paper draws upon the history of Christianity in South Korea to critically explore the links between religion and modernization. It makes two arguments. First, discussions of the link between religion and modernization frequently employ static definitions of religion, but Christianity is characterized by oscillations between worldly (institutionalizing) and unworldly (countercultural) impulses that theoretically make very different contributions to social, economic, and political development. Second, in the case of South Korea, it is shown that both impulses have made vital contributions to the country's modernization at different times. This suggests that the dynamic tug-of-war between the institutional and countercultural facets of Korean Christianity, although problematic for individual believers and religious leaders, helped it become an important contributor to the country's success story. However, this paper concludes on a cautionary note by warning that extreme instances of these impulses have caused cleavages between Christianity and the Korean state and society and could undermine its future contributions. This suggests that diversity and toleration—a hallmark of Korean Christianity—will continue to be the best pathway forward. [ABSTRACT FROM AUTHOR]

Medical students are potential marketing targets for pharmaceutical companies because established prescribing habits are not easily altered. In 2014, Bruno Etain and several other researchers published a paper which investigated the knowledge of and opinions on potential conflict of interest (COI) with regard to preclinical and clinical students enrolled in medical schools in France and residents working in hospitals. An empirical survey study with Korean medical students concerning their educational experiences and views on conflicts of interest and comparing and contrasting the results with Etain's study of French medical students. Receipt of direct or indirect financial offerings from pharmaceutical industries was not properly recognised as COI by the medical students. Therefore, strengthening education on COI and implementing institutional improvements for COI disclosure are essential to prevent bias caused by COI and enhance awareness levels regarding COI.

This paper aims to analyze how the traits of candlelight protest participants have changed from 2004 to 2017 in South Korea. While previous studies have typically identified these traits of the candlelight protesters based on a single survey, this paper examines the change of protest participants using a multi-level analysis. This study argues that voter type and election cycles have a significant impact on an individual's decision to participate in candlelight protests. To be specific, swing voters are less likely to participate in a candlelight protest when the next election is scheduled either too soon or too far. Core liberal voters with a high degree of motivation are more likely to take part in a candlelight protest when the distance from the next election is close, while core conservative voters with a low degree of motivation are not affected by the distance from the next election. This study contributes on both sub-fields, voting behaviors and contentious politics, by combining individuals' voting patterns with political opportunity structures. Survey data (2004, 2010, 2017) conducted by the Korean Political Science Association (KPSA) and the Korean Social Science Data Center (KSSDC) provide empirical support for the arguments.

Foreign bodies (FBs) in the nasal cavity are commonly encountered in otorhinolaryngology. This retrospective study was conducted between January 2009 and December 2020. The nasal FB frequencies were investigated according to age and sex. The type, shape, and location of the FBs, onset, and clinical features were obtained. In a total of 1228 cases, the average age was 3.9 ± 5.7 years. We found a higher incidence in patients 2–4 years old. The most frequent nasal FBs were beads (24.0%), toys/plastics (17.8%), and beans/corn (15.8%). However, there were some differences in the nasal FB types according to the age group. There was no difference in the location of the nasal FBs according to age group, but nasal FBs were found more frequently in the right nasal cavity in the 1–3-years-old groups. Most patients (97.5%) visited the hospital the same day when the nasal FB insertion was suspected, and most were asymptomatic. After the removal of the nasal FBs, most patients were free of complications. Of the nine cases involving button batteries, septal perforation was observed in two patients who visited the hospital one or two days after the FB insertion. There were specific age-based characteristics of the nasal FBs that may serve as a basis for specific precautions. [ABSTRACT FROM AUTHOR]

Through an investigation of two recently discovered paper sheets of the Incantation of Wish-Fulfillment from the Silla kingdom, this paper reveals that early Korea had more diverse forms of dhāraṇī practices than previously assumed. Through analyses of these incantation sheets, this paper contributes toward filling the gap in our current understanding of the material practice pertaining to the Incantation of Wish-Fulfillment of medieval East Asia. Previously, all known traces of material dhāraṇīs from early Korea, with just a few exceptions, were related to the Sūtra of the Pure Light Incantation enshrined in the relic crypts of pagodas—a practice that has little connection to contemporaneous Chinese dhāraṇī practice. However, the newly discovered Incantation of Wish-Fulfillment sheets, whose date this paper infers to be between the eighth and ninth century, show that Unified Silla had a dhāraṇī practice closely linked to coeval Chinese practice. The Incantation of Wish-Fulfillment sheets from Silla show the modification and continuation of Chinese dhāraṇī practice. Unlike the Chinese amulet sheets of the Incantation of Wish-Fulfillment that were buried in tombs, the Silla amulet sheets were likely enshrined in one of the pagodas erected on Mount Nam in Silla's capital. At the same time, they were placed in the pagoda to wish for good afterlives of the soldiers who died at the battle, suggesting that they had a mortuary function similar to those buried in Chinese tombs.

In South Korea, Renewable Energy Sources (RES) have been increasing with the application of energy policies, such as Feed in Tariff (FIT) and the Renewable Portfolio Standard (RPS). However, a rapid increase in RES supply leads to an uncertain power supply due to the intermittent output of RES. A representative example is the curtailment of Wind Turbines (WT), which frequently occurs in Jeju Island, South Korea. The proportion of RES power on Jeju Island is 67%, and there are cases where WT is curtailed among the operable sections to maintain the balance of power supply and demand. This paper applies Power-to-Gas (P2G) technology to hydrogenate, store, and utilize unused power to solve this problem. In this paper, Aewol-eup in Jeju Island is selected as a target site for case study. An Integrated Energy System (IES) for various energy operations is designed to control RES output. This paper proposes the optimal facility configuration and finally drives the optimal design and operation solution of IES by analyzing the objective functions and focusing on the Independent Power Producer (IPP) perspective.

This work investigates the possibility of isolating cellulose nanofibers from pulps of tall goldenrod plant, which are invasive plants in Korea, by a convenient method, without strong acids or high-pressure homogenization, using electron beam irradiation (EBI). The obtained cellulose nanofibers were characterized by scanning electron microscopy (SEM), ultraviolet–visible (UV–vis) spectroscopy, X-ray diffraction (XRD), thermogravimetric analysis (TGA), and in terms of their mechanical properties. SEM showed that the initially isolated 10-μm-diameter cellulose fibers became more finely separated with increasing EBI dose, and that cellulose fibers treated with 300 kGy of EBI were separated into long cellulose nanofibers of around 160 nm in diameter. In addition, the paper samples prepared from more finely separated fibers generated by using higher doses of EBI had enhanced UV–vis transmittance. Via the XRD analysis, we observed that cellulose I in the EBI-treated cellulose fibers were gradually converted into a different type of cellulose similar to cellulose type II, as the EBI dose increased. Meanwhile, the TGA demonstrated that the finely separated cellulose fibers observed after administering the high EBI dose had lowered thermal stability due to the reduction of cellulose I but higher char yield. In addition, tensile strengths of paper samples increased with decreasing the diameters of their constituent fibers that result from the different EBI doses used in the preparation of the paper pulp.

Traditional wisdom on how late industrialized countries follow the technology trajectories of preceding economies is in need of reformation as these countries have attained industrial leadership in a growing number of fields. However, current understandings about these countries' development of their emerging technologies have yet to investigate the divergence of idiosyncratic technology trajectories. The aim of this paper was to explore how their knowledge production strategies in emerging technology sectors are diverging. Specifically, this research examines the changing patterns of knowledge production in quantum technology in South Korea and China by developing a knowledge portfolio and knowledge strategic diagram. According to the knowledge portfolio, the relative literature position differs. In the knowledge strategic diagram, there are diverging patterns in the emerging keywords sector. This paper contributes to the literature by demonstrating the diverging strategies of late industrialized countries in their transition from catch‐up to post‐catch‐up paradigms and provides policy implications for countries developing an idiosyncratic trajectory in emerging technology sectors.

The adoption of recommender systems in business-to-business (B2B) can make the management of companies more efficient. Although the importance of recommendation is increasing with the expansion of B2B e-commerce, not enough studies on B2B recommendations have been conducted. Due to several differences between B2B and business-to-consumer (B2C), the B2B recommender system should be defined differently. This paper presents a new perspective on the explainable B2B recommender system using the knowledge graph attention network for recommendation (KGAT). Unlike traditional recommendation systems that suggest products to consumers, this study focuses on recommending potential buyers to sellers. Additionally, the utilization of the KGAT attention mechanisms enables the provision of explanations for each company's recommendations. The Korea Electronic Taxation System Association provides the Market Transaction Dataset in South Korea, and this research shows how the dataset is utilized in the knowledge graph (KG). The main tasks can be summarized in three points: (i) suggesting the application of an explainable recommender system in B2B for recommending potential customers, (ii) extracting the performance-enhancing features of a knowledge graph, and (iii) enhancing keyword extraction for trading items to improve recommendation performance. We can anticipate providing good insight into the development of the industry via the utilization of the B2B recommendation of potential customer prediction. [ABSTRACT FROM AUTHOR]
