s characterized by fractures, conduits, and interconnected channel networks that significantly influence groundwater flow dynamics. This literature review aims to synthesize current knowledge regarding the effects of karst on water circulation and permeability in carbonate aquifers based on hydrogeological, hydrochemical, geophysical, and numerical modeling studies from various regions worldwide. The review shows that karstification substantially enhances hydraulic conductivity and produces complex flow regimes ranging from diffuse fracture flow to turbulent conduit flow. The epikarst zone plays an important role in regulating infiltration and recharge distribution, while tectonic structures such as faults and fractures strongly control groundwater pathways and aquifer compartmentalization. Karst aquifers also exhibit strong spatial variability in permeability, making groundwater flow and contaminant transport difficult to predict using conventional hydrogeological approaches. In addition, the integration of equivalent porous medium (EPM), discrete fracture network (DFN), and conduit network (CN) models is essential for accurately representing karst aquifer behavior. Understanding the influence of karstification on groundwater circulation is therefore crucial for sustainable groundwater management and aquifer vulnerability assessment, particularly in regions facing increasing water demand and climate change pressures.

examines the effects of Return on Assets (ROA), Current Ratio (CR), Debt-to-Equity Ratio (DER), Sales Growth (SG), and Firm Size (SIZE) on Dividend Payout Ratio (DPR), as well as the impact of DPR on stock returns. The research employs a quantitative approach using secondary data obtained from the annual financial reports of dividend-paying companies listed on the IDX. The sample consists of 822 firm-year observations selected through purposive sampling. Data analysis was conducted using path analysis with multiple regression models, supported by classical assumption tests including normality, heteroscedasticity, multicollinearity, and autocorrelation tests. The results indicate that during the overall period of 2019–2024, ROA, DER, and SG significantly and negatively affect DPR, while CR and SIZE do not have significant effects. Furthermore, CR negatively affects stock returns, whereas SG and DPR have positive and significant effects on stock returns. The findings also reveal that the relationships among financial performance, dividend policy, and stock returns vary across pre-crisis, crisis, and post-crisis periods. Overall, dividend policy plays an important mediating role in influencing stock returns, particularly during and after periods of financial uncertainty. These findings provide valuable insights for investors, corporate managers, and policymakers in formulating dividend and investment decisions under different economic conditions.

ered less effective in maintaining children’s engagement due to limited opportunities for exploration and direct interaction during the learning process. In response to this condition, the concept of edutechment has emerged as an approach that integrates educational and entertainment elements to create more enjoyable and meaningful learning experiences. This study aims to analyze the implementation of edutechment at Taman Pintar Yogyakarta as a nonformal educational tourism space. This study employed a qualitative approach using a descriptive observational research design. Data were collected through direct observation, semi-structured interviews, documentation, and field notes involving child visitors, guides, and employees of Taman Pintar. The data were analyzed descriptively through the stages of data reduction, data presentation, and conclusion drawing. The findings revealed that Taman Pintar Yogyakarta has implemented the concept of edutechment through the integration of technology, multimedia, simulations, and educational play activities within various interactive attractions. Children were actively involved in exploration, experimentation, and direct interaction with learning media, creating more concrete and enjoyable learning experiences. However, the study also found that some children tended to focus more on entertainment aspects than on understanding educational concepts. Therefore, stronger facilitation and reflective learning strategies are needed to optimize the implementation of edutechment.
Abstract:This study aims to examine the strategic role of professional associations in early childhood education policy implementation, focusing on HIMPAUDI East Kalimantan. Non-formal early childhood educators in developing regions…
ons face severe structural vulnerabilities, characterized by a substantial policy gap between central government expectations and local capacities, geographical isolation, and low digital literacy. Utilizing a descriptive qualitative design, this research gathered empirical data through in-depth interviews with the Regional Head of HIMPAUDI East Kalimantan and document analysis. The findings reveal that the association does not merely serve as a gathering platform but functions as a vital strategic partner for local governments. Through multi-layered communication, self-funded tiered training programs, and data-driven political lobbying, the association successfully translates rigid macro-regulations into applicable classroom practices while securing local financial incentives for marginalized educators. This community-based resilience mechanism effectively mitigates administrative burdens and compensates for local government bureaucracy delays. The study implies that local governments should transition toward a co-governance model by formally involving professional networks in policy formulation to ensure equitable educational quality in the new capital city (IKN) era.

dicine, clinical decision support systems, and data-driven healthcare technologies. Despite rapid technological advancement, limited empirical evidence explains how healthcare professionals’ digital competence contributes to healthcare service performance within the context of healthcare transformation in Saudi Arabia. Previous studies have primarily focused on technological adoption or technical outcomes, while the psychological and organizational mechanisms underlying digital healthcare performance remain underexplored. Drawing upon the Job Demands–Resources (JD-R) Theory and Resource-Based View (RBV), this study investigates the influence of Digital Health Competence (DHC) on Healthcare Service Performance (HSP), examining the mediating role of Work Engagement (WE) and the moderating role of Organizational Support (OS). This study employed a quantitative cross-sectional explanatory design using Structural Equation Modeling–Partial Least Squares (SEM-PLS). Data were collected from 312 healthcare professionals at King Abdullah Medical City (KAMC), Saudi Arabia, selected through stratified random sampling. The study included physicians, nurses, pharmacists, and allied healthcare professionals actively utilizing digital healthcare systems in clinical practice. Measurement instruments were adapted from internationally validated scales, including the European Digital Competence Framework for Health Professionals, Utrecht Work Engagement Scale (UWES), and Perceived Organizational Support Scale. Data analysis included assessment of the measurement model, structural model evaluation, mediation analysis, moderation analysis, effect size (f²), predictive relevance (Q²), and model fit indices. The findings demonstrated that Digital Health Competence had a positive and significant effect on Healthcare Service Performance (β = 0.328, p < 0.001) and Work Engagement (β = 0.541, p < 0.001). Work Engagement significantly influenced Healthcare Service Performance (β = 0.462, p < 0.001) and partially mediated the relationship between Digital Health Competence and Healthcare Service Performance (β = 0.250, p < 0.001). In addition, Organizational Support significantly moderated the relationship between Digital Health Competence and Work Engagement (β = 0.217, p < 0.001). The structural model demonstrated substantial explanatory power (R² HSP = 0.683) and satisfactory predictive relevance. This study contributes theoretically by extending the application of JD-R Theory and RBV within the context of digital healthcare transformation in tertiary hospitals. The study proposes an integrated model demonstrating that digital competence functions not only as a technical capability but also as a strategic personal resource that enhances work engagement and healthcare service quality. Practically, the findings emphasize the importance of strengthening digital competency development, supportive organizational climates, and adaptive digital infrastructures to improve healthcare professionals’ performance and accelerate sustainable healthcare transformation in Saudi Arabia.
