This study examines the perceptual motivation behind dissimilation. Consistent with previous arguments suggesting that dissimilation originates from perception rather than production (Coetzee, 2005; Kiparsky, 2003; Scheer, 2013), we hypothesized that an oral stop with short of voice onset time (VOT) would be recognized as non-aspirated more often when it is followed by an aspirated stop with a long VOT. This hypothesis was tested through a perception experiment in which 32 Korean listeners made judgments on the first consonant of C₁VC₂V words manipulated with C₁ VOT and C₂ types. The results revealed that aspirated-based C₁ was recognized as aspirated or tense depending on the duration of VOT, while lenis-based C₁ was consistently recognized as lenis. The dissimilatory effect of aspirated C₂ was confirmed as anticipated, and furthermore, tense C₂ increased the ratio of tense responses more than aspirated C₂. These results provide evidence of a perceptual bias against recurrent aspirated stops, which may play a role in activating a dissimilatory rule or constraint in a language. The assimilatory effect of tense C₂ is in consistent with findings indicating that word-initial tensification is facilitated by the following tense stop in Korean (Kang & Oh, 2016; H. Kim, 2016).

Background: There is minimal literature on the morphology of partial distal biceps tendon (DBT) tears. We sought to investigate tear morphology by retrospectively reviewing 3-Tesla magnetic resonance imaging (3T MRI) scans of elbows with partial DBT tears and to propose a basic classification system. Methods: 3T MRI scans of elbows with partial DBT tears were retrospectively reviewed by two experienced observers. Basic demographic data were collected. Tear morphology was recorded including type, presence of retraction (>5 mm), and presence of discrete long-head and short-head tendons at the DBT insertion. Results: For analysis, 44 3T MRI scans of 44 elbows with partial DBT tears were included. There were 9 isolated long-head tears (20%), 13 isolated short-head tears (30%), 2 complete long-head tears with a partial short-head tear (5%), 5 complete short-head tears with a partial long-head tear (11%), and 15 peel-off tears (34%). Retraction was seen in 5 or 44 partial tears (11%), and 13 of the 44 DBTs were bifid tendons at the insertion (30%). Conclusions: Partial DBT tears can be classified into five sub-types: long-head isolated tears, short-head isolated tears, complete long-head tears with partial short-head involvement, complete short-head tears with partial long-head involvement, and peel-off tears. Classification of tears may have implications for operative and non-operative management. Level of evidence: III.

With the acceleration of regional economic integration, the agricultural trade network within the RCEP region presents new opportunities and challenges for member countries. This study focuses on agricultural trade among RCEP members from 2011 to 2020, utilizing social network analysis to explore the structural characteristics and evolutionary trends of the trade network. Additionally, an extended gravity model is employed to empirically analyze the key factors influencing South Korea's agricultural trade with other member countries. The findings reveal that: (1) Agricultural trade relationships within the RCEP region are stable and mature, with high interconnectivity in the trade network, indicating a trend towards balanced development. (2) The positions of member countries within the agricultural trade network are characterized by both high density and heterogeneity. (3) South Korea's agricultural trade with RCEP member countries is positively influenced by the economic size, population size, and governance level of its trading partners, while South Korea's own indicators show no significant effect. The trade distance between South Korea and member countries also has a positive impact on agricultural trade. By combining social network analysis with an extended gravity model, this study provides a multi-faceted quantitative analysis of the RCEP agricultural trade network, offering new insights into regional agricultural trade. It also provides empirical evidence for agricultural trade cooperation between South Korea and other RCEP countries.

Purpose: This study examines the impact of YouTube mukbang content characteristics on viewer satisfaction and word-of-mouth behavior. Drawing from theories in media psychology, consumer behavior, and communication studies, we investigate five key content characteristics: credibility, entertainment value, informativeness, visual appeal, and auditory quality. Research design, data and methodology: Using structural equation modeling with data from 206 mukbang viewers, we test hypothesized relationships between these characteristics, viewer satisfaction, and word-of-mouth behavior. Results: Research reveal that credibility and informativeness significantly and positively influence viewer satisfaction, while entertainment value, visual appeal, and auditory quality show no significant effect. Viewer satisfaction positively impacts word-of-mouth behavior. These findings challenge conventional assumptions about video content consumption and highlight the unique nature of mukbang viewing. Conclusions: The study contributes to digital content consumption literature by providing empirical evidence of factors influencing viewer engagement in the mukbang context. It offers practical insights for content creators, marketers, and platform developers, emphasizing the importance of informative and credible content in driving viewer satisfaction and promoting positive word-of-mouth. By extending established media theories to this emerging form of digital entertainment, our research paves the way for future studies. The study's limitations, including its cross-sectional nature and specific cultural context, suggest directions for future research.

Large language models (LLMs) are rapidly transforming medical writing and publishing. This review article focuses on experimental evidence to provide a comprehensive overview of the current applications, challenges, and future implications of LLMs in various stages of academic research and publishing process. Global surveys reveal a high prevalence of LLM usage in scientific writing, with both potential benefits and challenges associated with its adoption. LLMs have been successfully applied in literature search, research design, writing assistance, quality assessment, citation generation, and data analysis. LLMs have also been used in peer review and publication processes, including manuscript screening, generating review comments, and identifying potential biases. To ensure the integrity and quality of scholarly work in the era of LLM-assisted research, responsible artificial intelligence (AI) use is crucial. Researchers should prioritize verifying the accuracy and reliability of AI-generated content, maintain transparency in the use of LLMs, and develop collaborative human-AI workflows. Reviewers should focus on higher-order reviewing skills and be aware of the potential use of LLMs in manuscripts. Editorial offices should develop clear policies and guidelines on AI use and foster open dialogue within the academic community. Future directions include addressing the limitations and biases of current LLMs, exploring innovative applications, and continuously updating policies and practices in response to technological advancements. Collaborative efforts among stakeholders are necessary to harness the transformative potential of LLMs while maintaining the integrity of medical writing and publishing.

The endoplasmic reticulum (ER) is crucial for protein synthesis, transport, and folding, as well as calcium storage, lipid and steroid synthesis, and carbohydrate metabolism. Endoplasmic reticulum stress (ERS) occurs when misfolded or unfolded proteins accumulate in the ER lumen due to increased protein secretion or impaired folding. While the role of ERS in disease pathogenesis has been widely studied, most research has focused on extraoral diseases, leaving the role of ERS in intraoral diseases unclear. This review examines the role of ERS in oral diseases and oral fibrosis pathogenesis. A systematic search of literature through July 2023 was conducted in the MEDLINE database (via PubMed) using specific terms related to ERS, oral diseases, and fibrosis. The findings were summarized in both table and narrative form. Emerging evidence indicates that ERS significantly contributes to the pathogenesis of oral diseases and fibrosis. ERS-induced dysregulation of protein folding and the unfolded protein response can lead to cellular dysfunction and inflammation in oral tissues. Understanding the relationship between ERS and oral disease pathogenesis could offer new therapeutic targets for managing oral health and fibrosis-related complications.

The purpose of this study was to develop a scale to measure the psychological phenomena experienced by firefighters at disaster sites. After a literature review and verifying the content validity with firefighters and related experts, a questionnaire was developed, and a survey was conducted on 344 firefighters. Through factor analysis, the "Disaster Psychology Scale" was completed, which is divided into two subscales: "The Effects of Stress and Trauma" and "Automatic Response and Initial Judgment Errors." Both subscales showed excellent model fit, and the internal consistency reliability was also high. Additionally, significant results in content validity and construct validity confirmed that this is a valid scale. The scale developed in this study can be used as a tool for self-assessment of physical and mental health behaviors at disaster sites experienced by firefighters, and it can also serve as a useful tool for evidence-based interventions through the assessment of disaster-related psychological behaviors in firefighters.

Purpose - The purpose of this study was to analyze the impact of cultural distance, economic distance, and geographic distance on the export of Korean broadcasting programs by using data from 2013 to 2022 between Korea and nine regions in the Asia-Pacific. Design/methodology/approach - This study conducted a panel regression analysis using pooled cross-sectional time series data extracted from a ten-year dataset of nine Asia-Pacific regions: Japan, China, Taiwan, Singapore, Hong Kong, Vietnam, the Philippines, Indonesia, and Thailand, which are the main export destinations for Korea broadcasting programs. Findings - Firstly, economic and geographic distance, key determinants in the traditional gravity model, were found to significantly influence the export of Korean broadcasting programs. Secondly, while cultural distance showed a positive correlation with the export value of Korean broadcasting programs, an non-linear inverted U-shape relationship was observed when considering the squared term of cultural distance. Research implications or Originality - The findings of this study contribute to the existing literature by providing empirical evidence that the factors influencing the traditional gravity model remain significant determinants of Korean broadcasting program exports. While previous studies have primarily emphasized economic variables, this study underscores the importance of cultural factors in explaining the export of Korean broadcasting programs.

Ever since the UN Summit agreed on the MDGs in 2000, OECD/DAC member countries have taken poverty reduction as the main goal of their aid. To achieve this goal, all donors and recipient countries agreed on the Paris Declaration on Aid Effectiveness in 2005. To monitor and evaluate the progress in the targets of the Declaration, all donors and recipients got together periodically, and the 2011 conference was held in Busan, Korea. As part of this effort, this paper aims to assess the extent to which DAC donors have allocated their aid to achieve the MDGs during the latest millennium era: 2005-2009. In addition, to compare the aid allocation performance between DAC members and non-DAC emerging donors, this paper also assesses the aid allocation performance of Korea (KOICA) for the same period. The analysis of this paper shows evidence contrary to the recent literature findings that donors tended to select, as their aid recipients, those countries that warranted more aid on account of their acute development needs, and good policies and institutions. The difference between the recent literature and this paper is attributed to the different sample periods and/or the weaknesses of the estimation models and methods adopted in the literature. This paper shows why a different estimation method is adopted and why its estimation results are more reliable and convincing. This paper also shows the difference between DAC and non-DAC donors in the aid allocation performance by analyzing aid allocations by the representative aid agency of Korea (KOICA), and recommends some policy measures to be taken by both DAC and non-DAC donors.
