The current study examines the digital behaviors of 124 university students enrolled in a blended learning class in Korea. The students were divided into two groups (upper and lower) based on their scores on a self-regulated learning questionnaire. Their digital behaviors were compared across four areas: (a) task completion scores; (b) strategy use; (c) the days on which tasks were completed; and (d) learning gains. The results revealed a significant difference in task completion scores between the upper and lower groups. However, no meaningful difference was observed in strategy use between the two groups. Students in the upper group were more proactive in completing videos, homework, and TOEIC tests, often finishing these tasks ahead of deadlines. In contrast, students in the lower group tended to complete their assignments on the due date. Finally, there were no significant differences in learning gains between the two groups. These findings may inform the design and management of online L2 learning programs.
This study was conducted to collect data from various regions of Jejudo Island, Korea to establish a more accurate and complete academic listing of mushrooms on the island by identifying and organizing them using base sequence analysis. The investigation was performed over five years, from 2019 to 2023, and included a total of nine sites in the southern, western, and eastern areas of Jejudo Island. In total, 481 unique mushroom varieties were collected during the study. These mushrooms included 387 specimens that were classified into 6 classes, 18 orders, 55 families, 118 genera, and 201 species, and 94 unclassified specimens for which the precise species was not known. The collected mushrooms classified by ecotype consisted of 148 species of saprophytes, 47 species of symbionts, and 6 species of parasites. Differences in occurrence patterns were also observed depending on topographical characteristics and vegetation. Finally, three climate-sensitive biological indicator species and two candidate species were also collected, as well as the tropical mushroom Macrocybe gigantea. This study identified 91 species of mushrooms that were previously unreportedon the Jejudo Island. According to the current findings and those previously reported, 7 classes, 26 orders, 123 families, 399 genera, and 1,102 species of mushrooms have been compiled on Jejudo Island to date.
This study investigates the common liaison errors made by Chinese learners of Korean, specifically focusing on the tendency to add redundant consonants, as identified in previous research. The primary aim is to verify prior findings that such errors, especially involving the addition of the same consonant, are particularly prevalent after the final /ㄴ/ consonant. The study uses both quantitative and qualitative methods to explore the influence of gender, region of origin, Korean proficiency, native language interference, and learners’ understanding of Korean phonological rules. Findings confirm that the addition of identical consonants in / ㄴ/ final consonant is indeed frequent and largely unaffected by learners’ region of origin or Korean proficiency level. However, female learners show a slightly higher error rate compared to male learners. Key contributing factors include differences in syllable structure and phonemic characteristics between Korean and Chinese, the impact of null consonants, and learners’ limited understanding of Korean syllable and consonant rules. These insights are valuable for Korean language educators in addressing phonological errors among Chinese-speaking learners.
The Institute for Planning and Evaluation of Agriculture, Food, and Rural Affairs (IPET) is a quasi-governmental agency established under the Ministry of Agriculture, Food, and Rural Affairs that efficiently supports the planning, management, and evaluation of research and development projects to foster food science and technology for agriculture, forestry, and fisheries. The results of this study were used to prepare basic data and identify research trends to help understand Korea's mushroom industry by analyzing the related research published in the final report of the Ministry of Agriculture and Forestry from 1995 to 2020. The annual research trends are as follows: 1 in 1995, 7 in 1998, 6 in 2000, 9 in 2003, 9 in 2006, 10 in 2008, 5 in 2012, 3 in 2015, 8 in 2018, and 4 in 2020. They increased rapidly from the second half of 1990 to the second half of 2010 but decreased thereafter. The research fields were as follows: quality and postharvest management (45 articles, 32.3%), cultivation and production (41 articles, 29.5%), facilities (19 articles, 13.7%), genetic breeding (14 articles, 10.1%), biotechnology (14 articles, 10.1%), and others (6 articles, 4.3%).
본 연구는 한국 정부의 코로나 19 지원정책이 한국 제조 기업의 혁신활동에 미 치는 영향을 실증분석한 연구이다. 선행연구에 따르면, 정부는 조세, 자금, 금융 지원 등 다양 한 정책을 통해 기업의 혁신활동을 촉진할 수 있으며, 실제 이러한 정책들이 기업의 혁신 활 동 및 성과에 긍정적 영향을 미치는 것으로 평가되어왔다. 그러나, 정부 지원 정책의 효과는 지원 유형과 기간에 따라 다를 수 있으며, 동일한 정책이라도 지원 분야 및 산업에 따라 그 효과가 달라질 수 있다. 본 연구는 과학기술정책연구원(STEPI)에서 제공하는 2020 한국기업 혁신조사(KIS)자료를 사용하여 팬데믹 기간 코로나19 지원정책의 효과를 실증분석하였다. 2017-2020년 한국 제조 산업에 속한 3,941개 기업을 대상으로 프로빗 및 성향점수매칭 방법 을 통해 분석한 결과, 팬데믹 기간 정부의 코로나 19 지원정책은 한국 제조 기업의 혁신활동 을 유지 및 증가시킬 확률을 높이는데 양의 유의미한 영향을 주었으며, 지원정책의 유형을 조세, 금융, 자금지원 정책으로 분리하여 분석해 보았을 때에도 개별 정책은 모두 기업의 혁 신활동을 유지 및 증가시킬 확률을 유의미하게 높이는 것으로 분석되었다.
예이츠의 후기 시는 삶과 죽음, 예술의 영원성에 대한 깊은 철학적 성 찰을 담고 있으며, 특히 동양 철학, 그 중에서도 장자의 사상과 밀접한 연관을 보인다. 장자는 자연의 흐름에 순응하며 삶과 죽음의 경계를 초월하는 무위와 초연함을 강조 했는데, 예이츠는 이러한 장자의 철학에서 중요한 영감을 받아 자신의 시적 세계를 확 장했다고 볼 수 있다. 특히 비잔티움으로의 항해 (“Sailing to Byzantium”)와 청금석 부조 (“Lapis Lazuli”)에 이러한 영향이 두드러지게 나타진다. 이 논문은 두 시가 어떻 게 장자의 사상을 반영하고 있는지를 분석하고, 예이츠가 동서양 철학을 통합하여 예 술적 초월을 탐구한 방식을 조명하고자 한다.
This study examined the differences in the use of {ne} and {je} in Korean dramas from the 1990s and 2010s in terms of gender and discourse situations. The research focuses on how male and female characters use {ne} and {je} differently in public and private contexts for each era, and how these patterns have changed over time. The findings are summarized as follows. First, in the 1990s, men primarily used {je} in public settings and alternated between {ne} and {je} in private contexts, indicating a context-dependent usage pattern. Women, on the other hand, mainly used {je} in both public and private situations, but {ye} appeared more frequently in public settings, showing that women also adjusted their usage according to the context. Second, in the 2010s, men used both {ne} and {je} regardless of the discourse context, while women predominantly used {ne} across contexts. Third, compared to the 1990s, the use of {ne} in public situations increased for both men and women in the 2010s, indicating a notable change, while no change was observed in private settings.
Korean English medium instruction (EMI) classes aim to foster active discussions and communicative interactions in English between instructors and students. However, many Korean students in these classes struggle due to their limited English proficiency. This paper examines the challenges faced by Korean EFL students in EMI environments, highlighting the necessity for support in both English and their native language to facilitate effective learning. It also identifies teaching strategies that have proven effective in helping these students navigate language barriers. The findings indicate that participants had difficulty developing their writing skills for assignments in EMI settings and encountered limited opportunities to communicate their understanding of course material with instructors. To address these challenges, it is important to assess students’ language skills and find a balance between Korean and English. Implementing flexible teaching methods can enhance the learning experience, making it more effective and supportive. By providing multiple approaches to learning, such as interactive activities or peer support, learning gaps can be bridged and overall educational outcomes enhanced.
Mesenchymal stem cells (MSCs) have emerged as a promising therapeutic resource for the peripheral nervous system (PNS) and central nervous system (CNS) that is attributable to their capacity for neuronal differentiation. Human dental pulp stem cells (hDPSCs), which exhibit MSC-like traits, can differentiate into neuron-like cells and secrete critical neurotrophic factors; however, their therapeutic potential in peripheral nerve injury remains unexplored. This study investigated the regenerative effects of hDPSC transplantation following sciatic nerve injury (SNI) in rats. Transplantation of hDPSCs, STRO-1+ hDPSCs, or CD146+ hDPSCs after sciatic nerve transection in rats upregulated the levels of β3 tubulin, a marker of immature newborn neurons. Furthermore, the levels of glial cellderived neurotrophic factor, insulin-like growth factor 2, and the neuroregenerative factor NeuroD1 were upregulated. Motor dysfunction in rats with SNI was restored, as demonstrated by significantly higher sciatic functional index scores compared with the sciatic nerve transection group without transplantation. Transplantation of hDPSCs into injured peripheral nerves results in the upregulation of neurotrophic factors, differentiation into immature neurons, and promotion of motor function recovery. This approach holds promise as a valuable therapeutic strategy for repairing injured peripheral sciatic nerves, potentially providing a solution for nerve damage in both the PNS and CNS.
Periodontal disease has been implicated in the progression of various systemic diseases, including chronic kidney disease (CKD). Recent evidence suggests that infection of Porphyromonas gingivalis , a major periodontal pathogen, may also contribute to vascular calcification in patients with CKD. In the present study, antibody array analysis of serum samples from CKD mice administered with oral P. gingivalis revealed significant alterations in protein expression profiles, with notable interleukin-7 (IL-7) upregulation. We demonstrated that P. gingivalis infection enhances the inorganic phosphate-induced calcification of vascular smooth muscle cells (VSMCs), a pathological process that is characteristically accelerated in CKD. Notably, IL-7 expression was significantly upregulated in the P. gingivalis -stimulated calcification of VSMCs. Moreover, IL-7 knockdown in VSMCs markedly attenuated the P. gingivalis -stimulated calcification of VSMCs and suppressed the expression of osteogenic markers, including alkaline phosphatase and Runt-related transcription factor 2. These findings suggest that IL-7 plays a crucial role in P. gingivalis -stimulated vascular calcification, potentially providing new therapeutic targets for preventing vascular calcification in CKD patients with periodontal infection.
청소년의 스마트폰 과다 사용에 대한 우려가 증가함에 따라, 스마트폰 의존과 과다 사용이 정신 건강에 미치는 잠재적 영향에 대한 관심이 집중되고 있다. 그러나 스마트폰 의존과 자살 시도 간의 관계에 대한 직접적인 실증 연구 는 여전히 부족한 실정이다. 본 연구는 이러한 연구 공백을 메우기 위해, 청소년의 스마트폰 의존, 외로움, 그리고 자살 시도 간의 관계를 검토하고자 한다. 2023년 질병관리청의 조사 자료를 활용하여 800개 중⋅고등학교의 52,880 명의 학생을 분석한 결과, 스마트폰 의존도가 높은 청소년들은 지난 1년간 외로움과 자살 시도를 보고할 가능성이 유의미하게 높은 것으로 나타났다. 또한, 외로움은 스마트폰 의존과 자살 시도 간의 관계를 부분적으로 매개하는 것으로 밝혀져, 스마트폰의 과다 사용이 사회적 고립을 촉진하여 자살 위험을 증가시킬 수 있음을 시사한다. 아울러, 일상 스트레스는 중요한 조절 변수로 작용하는 것으로 나타났다. 스마트폰 의존, 외로움, 자살 위험 간의 연관성은 높은 스트레스 수준을 가진 청소년에게서 더욱 강하게 나타났다. 이러한 연구 결과는 외로움과 스트레스와 같은 심 리사회적 요인이 스마트폰 사용과 정신 건강 위험 간의 연관성에서 중요한 역할을 한다는 점을 부각시킨다. 본 연구 는 청소년의 스마트폰 과다 의존을 방지하고, 사회적 관계 강화를 중시할 필요성을 제안하며, 특히 스트레스 수준이 높은 청소년의 스마트폰 사용에 대해 더욱 많은 주의를 기울여야 함을 강조한다.
This collaborative action research aimed to develop and evaluate an academic Korean curriculum for immigrant students in grades 5~6, analyzing its effects on students’ academic Korean achievement and examining teachers’ perceptions of teaching academic Korean during the process. For this purpose, the collaboratively developed academic Korean curriculum was reviewed, and the academic Korean achievement of immigrant students was quantitatively analyzed through three assessments. Additionally, qualitative analysis was conducted on student interviews and teacher discussions regarding their experiences with the curriculum. The results indicated that the developed curriculum had a positive impact on the students’ academic Korean proficiency and their learning in other subjects. However, learning difficulties and elevated levels of anxiety during the course were common among students, regardless of their achievement levels. The teachers involved in the collaborative process proposed several strategies for more effective academic Korean teaching, such as expanding individualized support and strengthening connections with students’ families and homeroom classes. The significance of this collaborative action research lies in its empirical demonstration of the characteristics of academic Korean teaching, an area that has not been extensively covered in existing research on Korean language education.

The Qi Family Tree Bone Inscription refers to the Xia dynasty king list, and the deciphered bone names match the names of the Xia kings recorded in the classics. First, this bone inscription is authentic according to Sarah Allan and Kuang Yu Chen’s recent study of the engraved strokes of script viewed under microscope. Secondly, this paper introduces the interactive events between Xia Si (夏姒) people and Shang royal people in the Shang bone texts, such as the Shang conquest of the Xia Si, using the Xia people to serve the Shang King affairs, resettling the Xia people north and letting them fight others. This paper specifically interprets the bone scripts of Xia Si to mean that Xia indicates lowland for farming, and Si is the family name of the Xia recorded in the classics. The script for Si (surname) is derived from the image of a silkworm, as the Si are a silkworm totem people. Another decoded script for Xia is a river name, Xia (river) is named after “canal digging and irrigating”. Third, this paper deduces that the Xia people were living in the Jiang Xia (now Jiang Han or Jiang and Han rivers) plains, the Shijiahe site is the ruins of the Xia or Pre-Xia, and a large number of the Shijiahe red pottery figurines for dances were unearthed, which is consistent with the Xia dance and music recorded in the classics. The unearthed jade statues of deities look like silkworm moths, which corresponds to Xia Si being a sericulture tribe. After the Shijiahe culture, the Xia people built a last capital at Panlongcheng (or Panlong City), near the Xia River outlet. Because the classic Poem for the war epic named Shang Hero (殷武) says, “Got there the hero Cheng Tang (達彼殷武), went to conquer Jing Chu in strength (奮伐荊楚, Jing Chu 荊楚is the alternative name of Jiang Xia 江夏).” Another classic Poem for the Shang national epic called Long Growth (長發) says, “The states of Gu and Wei have been conquered (顧韋既伐).” The Gu and Wei are the current Xiangyang 襄陽 and Suixian 隨縣 on the east and west pathways to the Jiang Xia Basin from the Yellow River Basin, based on their ancient names and their sounds being homophonic. After occupying the states of Gu and Wei, the Shang army went south to form a situation of surrounding the Panlongcheng site of the Jiang Xia Plain. Thus, King Jie of Xia gave up the capital and went north to through the Ming Pass (present-day Wusheng Pass 武勝關) to the Huai River Plain of the East People 東夷, and there was the Battle of Ming Tiao in the Ming Pass. Finally, this study introduces an article about the oracle bone script ten classifications or designs, explaining how to decipher a script. The script for names engraved on the bone tablet were deciphered, corresponding to the name of the Xia Emperors in the classics. The meaning of the deciphered characters of the Xia Emperor names is consistent with the deeds of the Xia Emperors recorded in the classics. In the Qi family genealogy, there are inscriptions of the event of an older brother dying and his younger brother assuming the throne, which matches the record in the classics.
The oral microbiome plays a vital role in maintaining oral and overall health and affects immune responses, digestion, and pathogen suppression. While most studies focus on age groups prone to specific conditions, such as dental caries in children or periodontal disease in older adults, limited data exist on preschool-aged children and young adults. This study investigates the composition and diversity of the oral microbiome between these age groups for enhanced understanding of a healthy oral microbiome. Microbial samples from the supragingival regions of 41 children and 31 young adults in Korea were analyzed using 16S rRNA gene sequencing. Alpha and beta diversity were assessed, and linear discriminant analysis effect size (LEfSe) identified taxa with significant differences in abundance between the groups. No significant differences in alpha diversity were observed between children and young adults however, beta diversity analysis revealed notably compositional differences. At the phylum level, Firmicutes were more abundant in children, whereas Actinobacteria were more prevalent in young adults. Genera such as Veillonella and Lautropia were more abundant among children, whereas Haemophilus and Rothia were more common among young adults. LEfSe analysis identified Veillonella rogosae and Lautropia mirabilis as more abundant in children, whereas Haemophilus parainfluenzae and Rothia dentocariosa were more prevalent in young adults. The observed differences suggest that children’s microbiomes are associated with biofilm development, while young adults’ microbiomes involve biofilm maturation and immune modulation. These findings highlight the age-related shift in oral microbiome composition, emphasizing the importance of monitoring these changes to support long-term oral health.
This study analyzed inductive and deductive instructional approaches for teaching grammar within a Presentation-Practice-Production grammar lesson. The participants of this study included 119 Korean university students enrolled in an English as a foreign language class, with approximately half receiving deductive instruction and the other half receiving inductive grammar instruction. The analysis involved comparing learning gains as well as student perceptions of the two approaches via Mann Whitney U tests. The results showed no statistical difference in terms of the immediate or delayed learning gains for each grammatical topic, nor when all grammatical topics were aggregated. However, the analysis of student perceptions indicated that students found inductive instruction to be moderately more effective, interesting, and easier than deductive instruction. The study concludes with a discussion of the implications of these findings related to instructional practices in foreign language classes that utilize the Presentation- Practice-Production model as well as suggestions for future research concerning deductive and inductive instructional approaches.
본 연구는 씨릴 터너의 무신론자의 비극에서 주인공인 무신론적 자연주의자 담빌과 기독교의 섭리를 확고히 믿는 샤를몽과 카스타벨라를 대조함으로써 자연주의적 유물론과 전통적 기독교 관점의 도식적인 대결에 초점을 맞춘다. 이를 위한 분석에서, 본 연구는 터너가 구원과 섭리의 주제를 종교개혁 전후 당대의 종교적 담론의 관점에서 어떻게 묘사하고 있는지를 고찰한다. 무신론자의 비극은 종교개혁 이후 르네상스 연극의 특징을 담고 있으나, 선과 악, 심판과 형벌이라는 주제와 관련하여 전통적으로 중세 도덕극에 주로 등장하는 기독교적 심판을 제시하고 있다. 무신론자의 비극은 또한 종교윤리와 신의 섭리라는 개념을 다루며, 무신론자 담빌을 통해 인간의 책임을 강조한다. 르네상스 연극이 중세 기독교 교리를 인문주의 전통 속에서 해석한다면, 본 연구에서는 당시의 섭리적 담론에 대한 논쟁에도 불구하고, 후기 르네상스 작품에서 강조하는 종교적 도덕성과 비교하여 무신론자 담빌의 파멸을 통해 종교개혁 이후 신의 법과 영적 부패에 대한 기독교의 심판을 당대의 시대적, 종교적 담론 안에서 어떻게 반영하는지 비교 분석한다.
이 연구는 일반긴장이론, 사회유대이론, 일반이론에서 제안된 변인들을 사용하여 청소년의 비행지 속에 영향을 미치는 요인을 검증하고자 하는 것이다. 이를 위해 한국청소년정책연구원에서 실시한 아 동ㆍ청소년패널조사(KCYPS 2018)의 중1 패널의 2018년(1차)∼2022년(5차)의 자료를 결합하여 이산시간 위험모델을 통해 분석하였다. 분석결과 일반긴장이론의 긍정적 자극의 소멸, 친구긴장, 사회유대이론의 부모애착, 교사애착, 학업 열의, 참여, 일반이론의 자기통제력이 청소년 비행지속에 영향을 주는 것으로 나타났다. 이러한 연구 결과를 바탕으로 청소년 비행지속을 줄이기 위한 정책적 제언을 제시하였다. 이 연구는 청소년의 비행지속에 영향을 미치는 요인을 분석하기 위해 세 가지 비행이론을 사용하 여 패널데이터를 통해 종합적으로 검증했다는 점에서 중요한 의미가 있다. 그러나 2차 자료를 활용하 여 각 이론의 하위 변수들을 모두 활용하지 못했기에 검증에 한계가 있다.
