Patient safety culture is a critical component in healthcare organizations, reflecting the values, attitudes, competencies, and behavioral patterns that ensure safe patient care. This study aims to analyze the influence of knowledge and work environment on patient safety culture, with attitude serving as an intervening variable. A quantitative approach with an explanatory causal design was employed, involving 118 nurses as respondents selected through total population sampling. Data were collected using structured questionnaires and analyzed using Structural Equation Modeling with Partial Least Squares. The findings reveal that both knowledge and work environment have a significant direct effect on patient safety culture. Additionally, knowledge and work environment significantly influence attitudes, while attitudes themselves have a significant effect on patient safety culture. However, attitude does not mediate the relationship between knowledge and patient safety culture, but it does mediate the influence of the work environment on patient safety culture. These results indicate that improving nurses’ knowledge and creating a supportive work environment are essential strategies for strengthening patient safety culture. The study also highlights the importance of fostering positive attitudes through organizational support and conducive working conditions. The implications suggest that hospital management should focus on continuous training programs, enhancing workplace conditions, and developing systems that promote positive behavioral attitudes among healthcare workers to improve overall patient safety outcomes.

Differential equations involve derivatives of unknown functions and are widely used in mathematical modeling of various real-world problems. They can be classified based on linearity, homogeneity, coefficients, number of independent variables, degree, and order, thus requiring appropriate solution methods. One commonly used approach is the reduction of order method, which simplifies equations by reducing their order step by step. However, this method generally requires the solution of the corresponding homogeneous equation as an initial step. This study aims to solve nonhomogeneous linear ordinary differential equations of order with constant coefficients using the reduction of order method without determining the homogeneous solution. This research is a theoretical study based on relevant references concerning solution methods and types of differential equations. The procedure consists of two main stages: determining the fundamental symmetric polynomial variables based on the coefficients and constructing a sequence of solutions through first-order linear differential equations obtained from the reduction process. The results show that this method systematically produces the general solution of linear differential equations of order , making it an effective and efficient alternative approach

Stock market volatility represents a key indicator of financial market uncertainty, particularly in emerging economies where market structures are still evolving and are highly sensitive to global shocks. This study aims to analyze and compare the volatility dynamics of stock markets in four Asian emerging economies: Indonesia, India, Malaysia, and Thailand. The research employs a quantitative approach using daily stock index data from January 2011 to January 2026 obtained from Yahoo Finance. Stock returns are calculated using logarithmic transformation and analyzed using the Generalized Autoregressive Conditional Heteroskedasticity (GARCH(1,1)) model. Prior to model estimation, stationarity and ARCH effect tests are conducted to ensure the validity of volatility modeling. The empirical findings indicate that all return series exhibit non-normal distribution, strong volatility clustering, and significant ARCH effects. The estimation results show that both ARCH and GARCH parameters are statistically significant, with persistence levels close to unity across all markets, implying that volatility shocks tend to persist over a long period. These findings suggest that emerging stock markets in Asia are highly sensitive to external shocks and exhibit long-memory volatility behavior. The results provide important implications for investors and policymakers in designing effective risk management and market stabilization strategies.

separating and shredding organic and inorganic waste. This study aims to analyze the process of shredding household waste using the Computational Fluid Dynamics–Discrete Element Method (CFD-DEM) and determine the optimal operational parameters based on variations in rotor speed. The research method uses numerical simulation with SolidWorks 2024 software for geometric modeling and Ansys Rocky 2023 R1 for CFD-DEM simulation. The rotor speed variations used are 1000 RPM, 2500 RPM, and 4000 RPM with a mass flow rate of 4 tons/hour and a simulation duration of 2 seconds. The parameters analyzed included particle mass flow rate, shredding characteristics, and power consumption. The simulation results showed that a speed of 1000 RPM produced the most optimal performance with a maximum capacity of ±4 tons/hour and a stable shredding response compared to other variations. At 2500 RPM, there were high fluctuations with low capacity (±0.6 tons/hour), while at 4000 RPM, the capacity was moderate (±1.1 tons/hour) but still did not exceed the performance of 1000 RPM. Based on these results, it can be concluded that a rotor speed parameter of 1000 RPM is the most effective condition for improving the grinding efficiency and production capacity of a hammer mill-type Depackaging machine based on CFD-DEM simulation.

This study examines the effects of word of mouth, peer influence, and promotion on exercise decisions at gymnasiums in Bandar Lampung City, with hedonic motivation as a mediating variable. Drawing on the Theory of Planned Behavior and consumer behavior perspectives, the research employed a quantitative causal-associative design. Data were collected through structured questionnaires from 100 active members of four gymnasiums and analyzed using Partial Least Squares - Structural Equation Modeling (PLS-SEM) with SmartPLS . The results indicate that word of mouth, peer influence, and promotion have positive and significant effects on hedonic motivation and on exercise decisions. Hedonic motivation also exerts a positive and significant effect on exercise decisions, suggesting that pleasurable and emotionally rewarding fitness experiences reinforce consumers' intention to engage in regular gym- based exercise. Mediation analysis further reveals that hedonic motivation significantly channels the effects of peer influence and promotion on exercise decisions, while the indirect effect of word of mouth is also significant, although its negative coefficient warrants careful interpretation. These findings demonstrate that exercise decisions are shaped not only by utilitarian health considerations but also by social influence, promotional exposure, and affective consumption experiences. The study provides practical insights for gym managers in designing service and marketing strategies that strengthen customer engagement and sustained participation.

This literature study examines the process of self-regulation in transforming compliance with school rules originating from external pressure into behavioral regularity emerging from personal awareness, and its impact on the effectiveness of student learning outcomes. Using a qualitative approach with content analysis method, this study synthesizes relevant literature to build a theoretical framework on how self-regulation facilitates the internalization of disciplinary values. The findings reveal that self-regulation occurs through a series of interconnected stages including goal setting, strategy planning, self-monitoring, evaluation, and adjustment. The success of this process is determined by internal motivation, appropriate environmental support, positive direct experiences, and healthy emotional management. Strong self-regulation directly impacts learning outcome effectiveness through improved cognitive strategies, strengthened intrinsic motivation, enhanced time and environment management, and developed capacity to constructively cope with failure. Learning outcomes achieved through self-regulation processes are characterized by lasting understanding, knowledge transfer ability, and the formation of lifelong learning dispositions. Schools and teachers play strategic roles in strengthening self-regulation through curriculum design that supports autonomy, formative feedback, role modeling, and collaboration with parents. This study contributes theoretically by positioning self-regulation as the central mechanism bridging external influences and internal disposition formation.
