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.

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.

Abstract:This study aims to analyze the effect of Quick Ratio (QR), Debt to Asset Ratio (DAR), and Return on Assets (ROA) on firm value as measured by Price to Book Value (PBV) in consumer non-cyclical sector companies listed on…
the Indonesia Stock Exchange during the 2021–2024 period. The consumer non-cyclical sector was selected because it consists of companies producing essential goods with relatively stable demand, making it an important sector in the national economy. This research employed a quantitative approach using secondary data obtained from the annual financial statements of companies listed on the Indonesia Stock Exchange. The sampling technique used purposive sampling, resulting in 196 observations. Data analysis was conducted using multiple linear regression analysis with SPSS software, preceded by classical assumption tests including normality, multicollinearity, heteroscedasticity, and autocorrelation tests. The results show that partially, Quick Ratio has no significant effect on firm value, indicating that short-term liquidity is not the main consideration for investors in assessing company value. Debt to Asset Ratio also has no significant effect on firm value, meaning that the level of debt dependence does not directly determine market valuation. Meanwhile, Return on Assets has a positive and significant effect on firm value, indicating that profitability is the main factor influencing investor confidence and market value. Simultaneously, Quick Ratio, Debt to Asset Ratio, and Return on Assets have a significant effect on firm value. The coefficient of determination (R²) value of 0.510 indicates that 51.0% of firm value variation can be explained by the three independent variables, while the remaining 49.0% is explained by other factors outside this study.
Abstract:The growing emphasis on sustainable urban mobility has positioned electric vehicles (EVs) as a strategic component of transport transformation, particularly in developing cities with constrained infrastructure systems. One…
ne of the key challenges in supporting EV adoption is the provision of accessible charging infrastructure, which is closely related to user perception of acceptable service distance. This study aims to determine the optimal service distance of Electric Vehicle Charging Stations (EVCS) based on user preferences in Pekanbaru City, Indonesia, and to explore its implications for spatial planning. A quantitative approach was employed using a questionnaire survey of 51 respondents distributed across 15 administrative districts. All respondents were non-EV users, representing potential adopters in the early stage of transition. The survey captured preferred EVCS distance using interval-based categories, along with respondents’ awareness and intention toward EV adoption. The results indicate that the dominant preferred distance falls within the 2–4 km range, with an estimated mean of 3.08 km and a standard deviation of 1.98 km, resulting in an effective range of approximately 1–5 km. Considering urban road network constraints and detour factors, this range is further adjusted to 3–6 km to reflect more realistic travel conditions. These findings suggest that a relatively dense and accessible charging network is required to reduce range anxiety and support EV adoption. From a spatial planning perspective, a 4 km service threshold is proposed as a practical reference for EVCS deployment, representing the central tendency of user preferences within the adjusted range. This study highlights the importance of integrating user-based spatial parameters into infrastructure planning and contributes to the literature by emphasizing the role of perceived accessibility in shaping EV infrastructure demand in developing urban contexts.
Abstract:This study aims to analyze the effect of workload, multiple role conflict, and work stress on job satisfaction and their impact on the performance of female employees (nurses) at Permata Pamulang Hospital. The background…
of this research is based on the hospital’s unmet performance targets, high nursing workloads, the dominance of female employees, and the emergence of conflicts between work demands and family responsibilities that potentially increase stress and reduce job satisfaction. This research adopts a quantitative approach using a survey method. The population consists of all female employees (nurses) at Permata Pamulang Hospital, with a saturated sampling technique. Data were collected through questionnaires using a Likert scale and analyzed using path analysis to examine both direct and indirect relationships among variables. The results indicate that workload, multiple role conflict, and work stress have a significant effect on job satisfaction. Furthermore, job satisfaction has a significant effect on employee performance and acts as an intervening variable in the relationship between workload, multiple role conflict, and work stress on performance. These findings suggest that improving nurses’ performance can be achieved through proportional workload management, reducing multiple role conflicts, and controlling work stress to enhance job satisfaction. This study is expected to provide managerial insights for hospital management in formulating human resource policies that emphasize work-life balance and employee well- being.
