The purpose of this study is to investigate the contiguity of social capital and competence on business performance moderating by government policy. A total sample of 225 Village Credit Institution (LPDs) managers in Bali, the hypothesis is examined using the WarpPLS analysis. The findings reveal that social capital has an important role in enhancing performance, Competence is also an important factor for managers because it can intensify performance. Social capital is largely related to the recognition of society regarding the credibility of the managers, while competence emphasizes the ability of the managers to manage the organization. Government policy must be viewed as a regulation that is able to help improve performance. However, the public policies issued by the government are still unable to help improve social capital and competence. Thus, to create public policies that are able to improve the competence and social capital, a further examination into the variables must be conducted. The findings suggest that two-way communication must be developed and synergy between the government and organizations to create opportunities and overcome the increasingly complex business challenges. The results emphasized the importance of social capital in enhancing business performance. In addition, the role of competence is of equal importance to enhance business performance.

The effects of $MnO_2$ doping on the crystal structure, ferroelectric, and piezoelectric properties of (K,Na)$NbO_3$ (KNN) ceramics have been investigated. $MnO_2$ was found to be effective in enhancing the densification and grain growth during sintering. X-ray diffraction analysis indicated that Mn ions substituted B-site Nb ions up to 2 mol%, however, further doping induced unwanted secondary phases. In comparison with undoped KNN ceramics, the well developed microstructure and the substitution to B-sites in 2 mol% Mn-doped KNN ceramics resulted in significant improvements in both piezoelectric coupling coefficient and electromechanical quality factor.

Due to recent increased air traffic,, air traffic controllers in charge of en-route and approach control have faced huge increase in both workload and its intensity. The purpose of this paper is to analyze how much safety culture of air traffic controllers has effect on their complexity mitigation strategies during their duties. It could be expected complexity mitigation improve air traffic flow resulting in enhancing safety eventually. According to empirical analysis against air traffic controllers in civil aviation and air force in South Korea, it was proven safety culture had a statistically positive effect on complex mitigation strategies through safety behavior. In safety culture among air traffic controllers, intrinsic culture had a positive effect on extrinsic value of safety culture. Intrinsic value of safety culture led to air traffic controllers' safety behavior which created work complexity mitigation strategies. Among work complexity mitigation strategies, communication and cooperation was proven to be the most important factor effected by safety culture and behavior. It was implied that enhancing the intrinsic values of safety culture would cause to improve extrinsic safety culture and air traffic controller's work efficiency.

This study presents an online estimation of an excavator's rotational inertia by using recursive least square with forgetting. It is difficult to measure rotational inertia in real systems. Against this background, online estimation of rotational inertia is essential for improving safety and automation of construction equipment such as excavators because changes in inertial parameter impact dynamic characteristics. Regarding an excavator, rotational inertia for swing motion may change significantly according to working posture and digging conditions. Hence, rotational inertia estimation by predicting swing motion is critical for enhancing working safety and automation. Swing velocity and damping coefficient were used for rotational inertia estimation in this study. Updating rules are proposed for enhancing convergence performance by using the damping coefficient and forgetting factors. The proposed estimation algorithm uses three forgetting factors to estimate time-varying rotational inertia, damping coefficient, and torque with different variation rates. Rotational inertia in a typical working scenario was considered for reasonable performance evaluation. Three simulations were conducted by considering several digging conditions. Presented estimation results reveal the proposed estimation scheme is effective for estimating varying rotational inertia of the excavator.

This research aimed to validate the Korean version of the Workforce Agility Scale (K-WAS) among care workers for community-dwelling frail elderly. The study involved 192 care workers from Gyengsangnam-do, who completed a structured questionnaire between May 31 and July 15, 2023. The K-WAS, a 13-item instrument measured on a 5-point Likert scale, captures three key aspects of workforce agility: proactivity, adaptability, and resilience. Confirmatory factor analysis was employed to ascertain the scale's construct validity. The K-WAS demonstrated a significant positive correlation with psychological empowerment (r=.560, p<.001), thereby establishing its criterion validity. Although the results suggest that the K-WAS is a valid and reliable tool for assessing workforce agility among care workers, further refinement is recommended. The K-WAS is anticipated to aid in the implementation and evaluation of interventions focused on enhancing workforce agility among care workers for frail elderly. By providing a valid and reliable measure of workforce agility, the K-WAS can facilitate the evaluation of these interventions' effectiveness in improving outcomes for the frail elderly and_ enhancing the overall quality of care delivery.

Due to their stem-like characteristics and immunosuppressive properties, Mesenchymal stem cells (MSCs) offer remarkable potential in regenerative medicine. Much effort has been devoted to enhancing the efficacy of MSC therapy by enhancing MSC migration. In this study, we identified deubiquitinase BRCA1-associated protein 1 (BAP1) as an inhibitor of MSC migration. Using deubiquitinase siRNA library screening based on an in vitro wound healing assay, we found that silencing BAP1 significantly augmented MSC migration. Conversely, BAP1 overexpression reduced the migration and invasion capabilities of MSCs. BAP1 depletion in MSCs upregulates ERK phosphorylation, thereby increasing the expression of the migration factor, osteopontin. Further examination revealed that BAP1 interacts with phosphorylated ERK1/2, deubiquitinating their ubiquitins, and thus attenuating the ERK signaling pathway. Overall, our study highlights the critical role of BAP1 in regulating MSC migration through its deubiquitinase activity, and suggests a novel approach to improve the therapeutic potential of MSCs in regenerative medicine.

This Paper is Empirical Analysis of the Relationship between Authentic Leadership and Organizational Citizenship Behavior. It's important for enhancing corporate performance to facilitate positive interactions between leaders and members, and to cultivate a positive psychology for achieving common goals. Members with high positive psychological capital have confidence in performing their tasks, expect successful outcomes, and when problems arise, they adjust their course and persevere. This complex state of adjusting or transcending one's psychology is referred to as positive psychological capital (Luthans & Youssef, 2007). Recognizing this, the study identifies positive psychological capital as a crucial factor in enhancing corporate performance and competitiveness, and chooses it as a mediator in the research.
