Beyond Economic Benefit: How Justice, Empowerment, and Political Trust Shape Residents’ Support for Space Tourism

This study extends research explaining resident trust through cost–benefit evaluations of tourism development. In the context of space tourism development, a government-led initiative that offers residents limited participation and few direct benefits, we drew on Lefebvre’s right...

Evaluating the impact of incomplete contact tracing data on urban epidemic dynamics

Contact tracing (CT) is a frontline measure against emerging epidemics, yet in practice it is never complete. The quantitative impact of missing information—such as untraced cases or unnotified contacts—on the effectiveness of CT remains insufficiently understood. Using a stochas...

International Students’ Academic Adjustment in South Korea: A Qualitative Case Study

Although research on international students’ academic experiences in South Korean universities has steadily grown, relatively little attention has been paid to how undergraduate international students from diverse national backgrounds experience and navigate academic adjustment i...

Incidental Removal of an Aspirated Tooth During Routine Endotracheal Suctioning: A Case Report

Background/Objectives: Foreign body aspiration is a potentially life-threatening emergency that commonly requires bronchoscopic removal. Dental aspiration in elderly patients may occur following trauma, seizures, or altered mental status and can lead to airway obstruction and res...

Cancer nanovaccine plus doxorubicin and immune checkpoint blockade overcomes chemoresistance and delays postsurgical recurrence

Chemotherapy for solid tumors has serious limitations due to acquired chemoresistance and frequent postsurgical recurrence. In this study, we developed a chemo-immunotherapy regimen combining a chemotherapeutic agent, a dendritic cell (DC)-activating cancer nanovaccine, and immun...

Data-Driven Digital Twin for Amylosucrase from Deinococcus geothermalis : Accelerating Acceptor Discoveryin Transglycosylation Reactions

Abstract Enzymatic transglycosylation by Deinococcus geothermalis amylosucrase (DgAS) offers a cost-effective route for enhancing the physicochemical properties of bioactive flavonoids. However, predicting DgAS acceptor specificity remains challenging due to complex structure–act...

Hierarchical DefectEngineering for Spectral PhononControl in Monolayer MoS2

Abstract Two-dimensional (2D) transition-metal dichalcogenides are attractive for nanoelectronics and energy harvesting, where thermal transport critically impacts device reliability, performance, and energy efficiency. Here, we establish hierarchical defect engineering in monola...

Synergistic Integration of SrFeO 3 Nanoparticles With Exfoliated MXene (Ti 3 C 2 T x /V 2 CT x ) Nanosheets for High Performance Supercapacitors

ABSTRACT The performance of supercapacitors is often limited by conventional electrode materials, which typically necessitate a compromise between energy density, power density, and cycling stability. While two‐dimensional MXenes offer high conductivity and surface area, their pr...

The cultural gatekeeper: a three-level multilevel meta-analysis of the CSR attitude-behavior gap

Purpose Despite the global ubiquity of corporate social responsibility, the translation of favorable consumer attitudes into behavioral intentions remains erratic across international markets. While prior meta-analyses have examined cultural moderators, they have largely ignored...

Direct medical costs of breast cancer by subtype and stage in Korea: a patient-level retrospective cohort analysis

With the emergence of increasing subtype-specific treatments for breast cancer, the need for subtype-based cost assessments have been highlighted, given the lack of detailed molecular data in prior cost analyses. Therefore, this study aimed to estimate medical costs among Korean...

Status distance and employee innovation: the roles of knowledge sharing and psychological safety in South Korean high-tech firms

This study examines how status distance affects employees’ innovation through knowledge sharing and investigates psychological safety as a boundary condition. Using data from South Korean high-tech firms, we find that greater status distance reduces knowledge sharing, which in tu...
