RESUMEN

Digital sports, also known as online sports, are a new form of sport that users have tried in recent years. Despite the rapid growth of online sports, the factors influencing users' willingness to sustain their use are currently unknown. Based on the theory of planned behavior (TPB) and expectation-confirmation theory (ECT), this study empirically investigates the factors influencing the persistent use of online sports videos. Questionnaires were administered to participants. A total of 305 participants completed the questionnaire. Structural equation modeling showed that all hypotheses' paths were significant, except for H11 and H12. The results indicated that perceived usefulness, expectation confirmation, and coach social presence had a significant positive effect on users' satisfaction in using online sports videos. Moreover, satisfaction, behavioral attitudes, subjective norms, and perceived behavioral control had a significant positive effect on users' willingness to consistently use online sports videos, with gender moderating the impact of satisfaction and behavioral attitudes on the willingness to consistently use. We discuss the practical implications and recommendations for applying this study's findings.

RESUMEN

To investigate the effectiveness of the Clubhouse Model of Psychosocial Rehabilitation on psychosocial functions and recovery of native Chinese individuals with schizophrenia in a community sample. A randomized controlled design was used. A total of 56 participants were recruited from a community sample for a study lasting 6 months, but five participants dropped out. Twenty-eight participants attended the Clubhouse program, and twenty-three participants served as controls. Standardized assessments were performed on three areas at the baseline and the 6-month follow-up: 1. symptom reduction; 2. social function, self-determination, and quality of life; and 3. rehospitalization rate. Compared to the controls, the Clubhouse participants showed reductions in psychiatric symptoms and better social function, self-determination, and quality of life (p < .05), but with no difference in the rehospitalization rate between Clubhouse members and the controls. The Clubhouse Model demonstrates its effectiveness and shows its viability as a service delivery model in psychosocial rehabilitation for individuals with schizophrenia in mainland China.

RESUMEN

OBJECTIVE: To study the biocompatibility of the osteoblasts from adult human bone marrow with coral-derived hydroxyapatite (CHA) in in vitro culture. METHODS: Bone marrow was obtained from healthy adult subjects and cultured in Dulbecco's modified Eagle's medium (DMEM) containing 10 % fetal bovine serum. The subsequent cell passaging was conducted in conditioned medium containing dexamethasone, beta-sodium glycerophosphate and ascorbic acid, with the osteoblasts in culture then divided into CHA group (in which the cells were cultured with CHA) and osteoblasts group (without CHA). The proliferation and differentiation of all the cultured cells were observed at different time points under inverted phase contrast microscope, optical microscope with HE staining and scanning electron microscope respectively. Proliferation of the cultured cells were evaluated by MTT assay, and the activity of alkaline phosphatase and total micro-protein contents in these cultured osteoblasts were quantitatively detected. RESULTS: The osteoblasts from adult human bone marrow grow well in vitro, regardless of the presence of CHA, with biological and morphological characteristics similar to those of normal osteoblasts. CHA improved the adhesion, growth and proliferation of the cultured cells, showing no adverse effects on the cell functions. CONCLUSION: CHA is an optimal scaffold material for bone tissue engineering, which may potentially find clinical application for bone defect repair.
