        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.

        Bearing-shaft systems are essential components in various automated manufacturing processes, primarily designed for the efficient rotation of a main shaft by a motor. Accurate fault detection is critical for operating manufacturing processes, yet challenges remain in sensor selection and optimization regarding types, locations, and positioning. Sound signals present a viable solution for fault detection, as microphones can capture mechanical sounds from remote locations and have been traditionally employed for monitoring machine health. However, recordings in real industrial environments always contain non-negligible ambient noise, which hampers effective fault detection. Utilizing a high-performance microphone for noise cancellation can be cost-prohibitive and impractical in actual manufacturing sites, therefore to address these challenges, we proposed a convolution neural network-based methodology for fault detection that analyzes the mechanical sounds generated from the bearing-shaft system in the form of Log-mel spectrograms. To mitigate the impact of environmental noise in recordings made with commercial microphones, we also developed a denoising autoencoder that operates without requiring any expert knowledge of the system. The proposed DAE-CNN model demonstrates high performance in fault detection regardless of whether environmental noise is included(98.1%) or not(100%). It indicates that the proposed methodology effectively preserves significant signal features while overcoming the negative influence of ambient noise present in the collected datasets in both fault detection and fault type classification.

        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.

        MES(manufacturing execution system) plays a critical role in improving production efficiency by managing operations across the entire manufacturing system. Conventional manufacturing systems employ a centralized control structure, which has limitations in terms of the flexibility, scalability and reconfigurability of the manufacturing system. Agent-based manufacturing systems, on the other hand, are better suited to dynamic environments due to their inherent high autonomy and reconfigurability. In this study, we propose an agent-based MES and present its collaboration model between agents along with a data structure. The agent-based MES consists of three types of core agents: WIPAgent, PAgent(processing agent), and MHAgent(material handling agent). The entire manufacturing execution process operates through collaboration among these core agents, and all collaboration is carried out through autonomous interactions between the agents. In particular, the order-by-order dispatching process and the WIP(work-in-process) routing process are represented as respective collaboration models to facilitate understanding and analyzing the processes. In addition, we define data specifications required for MES implementation and operation, and their respective structures and relationships. Moreover, we build a prototype system employing a simulation model of an exemplary shop-floor as a simulation test bed. The framework proposed in this study can be used as a basis for building an automated operating system in a distributed environment.

        The purpose of this study is to develop a timely fall detection system aimed at improving elderly care, reducing injury risks, and promoting greater independence among older adults. Falls are a leading cause of severe complications, long-term disabilities, and even mortality in the aging population, making their detection and prevention a crucial area of public health focus. This research introduces an innovative fall detection approach by leveraging Mediapipe, a state-of-the-art computer vision tool designed for human posture tracking. By analyzing the velocity of keypoints derived from human movement data, the system is able to detect abrupt changes in motion patterns, which are indicative of potential falls. To enhance the accuracy and robustness of fall detection, this system integrates an LSTM (Long Short-Term Memory) model specifically optimized for time-series data analysis. LSTM's ability to capture critical temporal shifts in movement patterns ensures the system's reliability in distinguishing falls from other types of motion. The combination of Mediapipe and LSTM provides a highly accurate and robust monitoring system with a significantly reduced false-positive rate, making it suitable for real-world elderly care environments. Experimental results demonstrated the efficacy of the proposed system, achieving an F1 score of 0.934, with a precision of 0.935 and a recall of 0.932. These findings highlight the system's capability to handle complex motion data effectively while maintaining high accuracy and reliability. The proposed method represents a technological advancement in fall detection systems, with promising potential for implementation in elderly monitoring systems. By improving safety and quality of life for older adults, this research contributes meaningfully to advancements in elderly care technology.

        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.

        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.

        This study investigates the effect of team-teaching between Korean English teachers and native speakers of English on English learning anxiety. A total of 248 elementary students in grade 6 participated in this study. One group of students were taught by Korean English teachers and native speakers of English while the other group never had the opportunity to speak with a native speaker in class. A survey questionnaire based on FLCAS (Foreign Language Classroom Anxiety Scale) was newly developed to investigate how the two groups showed differences in English learning anxiety in class. The exploratory factor analysis was undertaken to suggest a three-factor solution. The two groups showed differences in English classroom anxiety and confidence in communication with native English speakers. On the other hand, fear of negative evaluation did not show any significant differences between the two groups. The students who experienced team-teaching showed more confidence in communication with native speakers only at a rudimentary level. Therefore, native English-speaking teachers should make their efforts to develop the skills to promote students’ confidence and higher level of communicative abilities.

        The purpose of this study is to identify bias-adjusted efficiency estimates and the determinants of efficiency in the Marine-Bio industry. Efficiency was estimated using the Bootstrap-DEA model, and efficiency determinants were analyzed by utilizing the dependent variables such as company age, number of employees, location within Marine-Bio clusters, R&D performance, and debt ratio. The efficiency analysis revealed that most of the DMUs belonged to the inefficient group with efficiency values below 0.7. The primary cause of inefficiency was identified as pure technical efficiency, which reflects the effectiveness of input combinations. In the analysis of efficiency determinants, it was found that the number of employees and the debt ratio had a positive (+) effect on efficiency. Conversely, engaging in R&D activities was found to have a negative (-) effect on efficiency.
