This study aimed to investigate the impact of scores on the Test of Proficiency in Korean (TOPIK) among foreign exchange students on academic adaptation. Recruited students, approved by the Institutional Review Board (IRB), totaled seven, and their interview contents were analyzed using a comprehensive analysis procedure based on pragmatic eclecticism (Lee, Kim, 2014), utilizing six stages. As a result, factors influencing academic adaptation of Korean language learners for academic purposes were categorized into three dimensions: academic, daily life, and psychological-emotional aspects. On the academic front, interviewees pointed out difficulties in adapting to specialized terminology and studying in their majors, as well as experiencing significant challenges with Chinese characters and Sino-Korean words. Next, from a daily life perspective, even participants holding advanced TOPIK scores faced difficulties in adapting to university life, emphasizing the necessity of practical expressions and extensive vocabulary for proper adjustment to Korean life. Lastly, within the psychological-emotional dimension, despite being advanced TOPIK holders, they were found to experience considerable stress in conversations or presentations with Koreans. Their lack of knowledge in social-cultural and everyday life culture also led to linguistic errors and contributed to psychological-emotional difficulties, despite proficiency in Korean. Based on these narratives, the conclusion was reached that in order to promote the academic adaptation of Korean language learners, it is essential to provide opportunities for Korean language learning. With this goal in mind, efforts should be directed towards enhancing learners' academic proficiency in their majors, improving Korean language fluency, and fostering interpersonal relationships within the academic community. Furthermore, the researchers suggested as a solution to implement various extracurricular activities tailored for foreign learners.

The purpose of this study was to develop self-evaluation criteria for objective verification and performance analysis of LINC 3.0. To achieve this goal, evaluation indicators in the fields of human resources development and skill development and commercialization were developed and their validity was verified. We investigated previous evaluation-related studies and similar cases to construct an evaluation model and system and develop indicators. The validity of the developed evaluation indicators was secured through two round Delphi surveys. As a result of the research, LINC 3.0 evaluation indicators can be divided into the field of human resources development and skill development and commercialization. A total of 66 evaluation indicators were developed. CIPP in the field of human resources development was developed with 13 categories and 38 evaluation indicators, and CIPP in the field of skill development and commercialization was developed with 12 categories and 28 evaluation indicators. The significance of this study is that it suggests a way to increase the objective verification and validity of the university industry-academia cooperation model by developing self-evaluation indicators for the LINC 3.0 project. The evaluation indicators developed in the research need to be continuously upgraded based on field usability, and it is necessary to improve the quality and competitiveness of university education by sharing and spreading excellent affairs.

The purpose of this study is to analyze domestic academic library development plans, check whether key components are reflected, and seek ways to improve the establishment of academic library development plans. To this end, a rubric evaluation technique derived from research related to evaluation of foreign universities and libraries was used. The libraries of the top 15 domestic universities were selected by referring to the QS World University Evaluation and THE World University Evaluation as the subjects of the study, and how much the core components of the development plan were reflected were evaluated. The results of the study are as follows. First, as a result of evaluating the university library development plan, most of the contents of 'purpose', 'goal', and 'action plan' were reflected, but vulnerabilities were found in 'mission' and 'vision'. Second, some private academic libraries were moving toward strategic planning at the level of advanced countries, including all of the core components. Third, although most academic libraries specified 'purpose', it showed limitations due to perfunctory description and connection. In the comprehensive evaluation, out of the highest score of 15, 12 were good and 3 were poor, indicating that the development plans of domestic academic libraries were generally at a 'good' level. As an improvement measure, it was suggested to form a task force for development plan establishment, to disclose and promote development plans, and to strengthen education on development plans for librarians.

Curcumin, the primary active compound in Curcumae Radix of the ginger family, exhibits a range of therapeutic effects, including blood sugar regulation, immunoregulation, antioxidant, antibacterial, and antitumor activities. However, its poor water solubility and chemical instability result in suboptimal pharmacokinetics with low oral absorption (0.18%) and bioavailability, thus limiting its efficacy. To overcome these limitations, this study aimed to enhance the oral absorption and bioavailability of curcumin by incorporating lysine and β-cyclodextrin. Following oral administration of solubilized cur- cumin, blood samples were collected to assess the oral absorption rate. Solubilized curcumin showed an approximately 1.55-fold increase in absorption at 120 min compared to its non-solubilized form. Furthermore, intravenous administration followed by blood analysis showed a 25-fold increase in bio- availability at 61 min for the solubilized curcumin compared to the non-solubilized variant. In conclusion, employing lysine for dispersion and stabilization, combined with β-cyclodextrin to enhance solubility, significantly improves curcumin's oral absorption and bioavailability. The results of this experiment are expected to lead to the development of herbal medicines and pharmaceuticals that amplify curcumin's anti-inflammatory, anti-tumor, and blood-sugar-regulation effects.

This study aimed to analyze the main forest environmental factors affecting the discernment of slow-moving landslide-prone areas in the Republic of Korea, based on data from a detailed landslide survey conducted from 2019 to 2021. Field survey data from 256 sites were collected covering 29 forest environmental factors in seven categories, including geology, soil, and topography. The analysis was conducted using the Random Forest model (AUC = 0.910) and XGBoost model (Accuracy = 0.808, Kappa = 0.594, F1 - measure = 0.494), which were evaluated as having high classification accuracy during the machine learning model development process. Consequently, factors with a high mean decrease Gini (MDG), representing classification importance, were identified as the presence of cracks (average MDG of both models: 22.1), peak elevation (14.8), and the presence of steps (7.0), indicating that these were significant factors in determining slow-moving landslide-prone areas. The presence of cracks and steps aligned well with the characteristics of slow-moving landslides, suggesting that their importance should be emphasized in future detailed landslide surveys. However, the influence of the peak elevation was considered somewhat overestimated due to the characteristics of the input data used in the analysis. These findings are expected to further improve the accuracy and efficiency of final judgments in detailed landslide surveys.

This study is a descriptive research study conducted to verify the dual mediating effect of critical thinking disposition and core nursing skill performance confidence in the relationship between clinical nurses' nursing professionalism and clinical decision-making ability and to use it as basic data for improving clinical decision-making ability. The study subjects were 173 clinical nurses at a general hospital in a region, and data were collected from September 15 to October 13, 2023. Data were analyzed using the SPSS/AMOS 23.0 program to verify the mediating effect by analyzing the causal relationship between the research variables and the bootstrapping estimation method, and t-test, ANOVA, Scheffe's test, Pearson's correlation coefficient, and hierarchical regression were performed. The results of the study include: First, the appropriateness of the causal model between clinical nurses' nursing professionalism, clinical decision-making ability, critical thinking disposition, and core nursing skill performance confidence was valid. Second, critical thinking disposition showed a partial mediating effect in the relationship between nursing professionalism and clinical decision-making ability. Third, as a result of verifying the dual mediating effect, the indirect effect of critical thinking disposition was greater than the indirect effect of critical thinking disposition and core nursing skill performance confidence, indicating that the single mediating effect was greater than the dual mediating effect. Therefore, it was verified that fostering high nursing professionalism in clinical nurses can improve clinical decision-making ability, and in particular, strengthening critical thinking disposition is more effective.

The use of composite materials for structural fasteners is increasingly common, making it crucial to assess the deformation of these fasteners under fatigue behavior. In this study, clamp-type fasteners were manufactured using carbon fiber reinforced composites, and their structural stability and sectional damage rates were evaluated using electrical resistance measurement during fatigue behavior. While clamp-type composite fasteners exhibited minimal deformation in flat sections, significant deformation occurred in the bent sections due to fatigue. It was observed that insufficient angular stability led to concentrated damage in the bent sections. The dynamic fatigue behavior showed that the length change rate of the composite fasteners was within 0.6%, but the angular change rate reached up to 6%, indicating that the bent sections are the most critical areas. By utilizing the self-sensing capability of the composite fasteners, sectional damage behavior was assessed through electrical resistance measurement. Significant damage was noted in the bent sections due to fatigue, and 3D-CT results revealed substantial deformation and interfacial damage when the initial bend angle of the fasteners was less than 90 degrees. These findings highlight the importance of reinforcing the stiffness of the bent sections and establishing systematic angular standards in the development of composite fasteners.

The rapid development of China's wind energy sector was facilitated by a number of transnational actors including organisations for international cooperation and international environmental organisations. This paper explores their evolving roles at different development stages in order to extend our understanding of the socio-political conditions for energy transition. Employing the framework of norm diffusion theories, this study focuses on the transnational advocacy group supporting wind energy for environmental purposes and analyses their norm promotion activities in interaction with domestic proponent as well as opponent groups. This analysis shows that the transnational actors successfully laid the foundation for the commercial wind energy development throughout the 1990s but experienced marginalisation during the sector expansion due to the dominance of the central government and its protectionist industrial policy. As the domestic opponent groups caused high-level wind curtailment in the 2010s, the international advocacy group has increasingly conducted offensive norm promotion activities. This case of the Chinese wind energy development suggests that the international transfer of technology and policy measures in combination with the mobilisation of economic resources support the growth of the wind energy sector, which nonetheless suffers lacking influence of environmental norms and faces conflicts with the traditional players of the electricity sector. Based on these findings, this study concludes that the key socio-political condition for energy transition is the formation of a power configuration which facilitates the effectiveness of environmental norms and thus confronts the powerful opponents of wind energy.

The purpose of this study is to deeply analyze the psychological influence of anxious attachment and projective identification on extramarital behavior. By systematically collecting and analyzing literature reviews, we explored how anxious attachment and projective identification are connected to extramarital behavior, strengthened the theoretical background, and suggested the possibility of application in counseling and treatment processes. We analyzed the possibility and pattern of extramarital behavior according to anxious attachment types (anxious, avoidant, and mixed types), and investigated whether projective identification plays an important role in justifying extramarital behavior and worsening relationships. The anxious attachment type tends to find stability in oneself through extramarital behavior due to the fear of being abandoned by the partner, while the avoidant attachment type tends to avoid emotional intimacy and maintain independence, and tends to distance oneself from the relationship through extramarital behavior. Mixed attachment is a state of mixed anxiety and avoidance, and tends to relieve extreme emotional changes through extramarital behavior. In addition, projective identification functions as a psychological mechanism that projects one's negative emotions and anxiety onto the other person and shifts responsibility for extramarital behavior to the other person. Through this, infidelity became a means to protect or justify oneself, which resulted in worsening the relationship. This study shows that anxious attachment and projective identification are important psychological backgrounds of infidelity, and it provides important implications for the development of counseling and treatment programs. It can be used as basic data for promoting individual psychological health and forming healthy relationships.
