Development of a Smart Health Care Service Using Metaverse and Chatbot Technologies for Adolescents, Parents, and School Health Teachers: User-Centered Design Approach

Development of a Smart Health Care Service Using Metaverse and Chatbot Technologies for Adolescents, Parents, and School Health Teachers: User-Centered Design Approach

The digital readiness items were derived from the tool developed by Kim et al [27]. The self-efficacy measurement tool for using digital media systems was based on research by Hong et al [28], with subsequent translation and modification by Kim [29] into Korean, which the researcher further adapted for this study.

Integrating the Situational Theory of Problem Solving and Technology Acceptance Model to Predict Intention to Practice Health Protective Behavior for Influenza-Like Illness Among TikTok Users: Cross-Sectional Study

Integrating the Situational Theory of Problem Solving and Technology Acceptance Model to Predict Intention to Practice Health Protective Behavior for Influenza-Like Illness Among TikTok Users: Cross-Sectional Study

The STOPS, developed by Kim and Grunig [15], builds on the earlier situational theory of publics to shift the focus from public engagement to individual cognitive and behavioral problem solving through communication. The STOPS conceptualizes individuals as active problem solvers who seek to address issues and their consequences [19]. The theory examines how problem recognition influences communicative behavior in problematic situations.

Enhancing the Predictions of Cytomegalovirus Infection in Severe Ulcerative Colitis Using a Deep Learning Ensemble Model: Development and Validation Study

Enhancing the Predictions of Cytomegalovirus Infection in Severe Ulcerative Colitis Using a Deep Learning Ensemble Model: Development and Validation Study

Histopathological techniques used for CMV diagnosis in UC include hematoxylin and eosin (H&E) staining, immunohistochemistry (IHC), and tissue DNA PCR (polymerase chain reaction). H&E staining identifies characteristic cytomegalic cells with nuclear inclusions and has high specificity (92%‐100%) but variable sensitivity (10%‐87%) due to observer dependency. IHC, which detects immediate early antigens of CMV, improves sensitivity (78%‐93%) while maintaining high specificity (92%‐100%).

Development and Effect of Prenatal Education Programs Using Virtual Reality for Pregnant Women Hospitalized With Preterm Labor: Experimental Study

Development and Effect of Prenatal Education Programs Using Virtual Reality for Pregnant Women Hospitalized With Preterm Labor: Experimental Study

The Cronbach α for the STAI in Kim and Shin’s [30] Korean version was 0.92, and it was also 0.92 in this study. Stress related to preterm labor was assessed using an instrument developed by Kim [31]. This tool consists of 17 items rated on a 5-point Likert scale, with total scores ranging from 17 to 85. Higher scores indicate higher levels of stress. The Cronbach α value was 0.79 in Kim’s original study [31], and 0.79 in this study as well.
