Purpose: Nursing clinical practice education is transforming with the advent of mobile education and the unique experiences it offers in caring for virtual patients. For this innovative approach, this study aims to evaluate the efficacy of mobile-based virtual women's breast cancer nursing simulation training content on nursing students' confidence, satisfaction, and learning flow. It also examines the nursing students' virtual patient care experiences. Methods: A mixed methods approach using a convergent design was employed to examine students' cancer care confidence and satisfaction, learning flow, and learning experiences. Quantitative data through online questionnaires and qualitative data through focus group interviews were collected, merged, and analyzed. Results: This study developed a virtual nursing training module aimed at caring for women with breast cancer, a novel approach to facilitate mobile-based simulation training for nursing students. Data were analyzed using descriptive analysis, a chi-squared test, Fisher's exact test, t-test for participant homogeneity (experimental: 20, control: 20), independent t-test, and paired t-test. Satisfaction (t=3.53, p=.001) and confidence (t=4.07, p=.001), as well as flow (t=3.78, p=.001), significantly improved in the experimental group compared to the control group. Two core themes and five sub-themes were derived from the experimental group's experiences acquired by caring for women with breast cancer virtually, including that the students "Virtually cared for breast cancer patients, learning as if real." Conclusion: The mobile-based virtual nursing simulation training content allowed nursing students to upgrade their comprehensive nursing care skills by experiencing a fun and practical environment made possible by a new learning method.

Background: The purpose of this study was to measure the time of the conventional surgical planning (CSP) and virtual surgical planning (VSP) in orthognathic surgery and to compare them in terms of cost. Material and method: This is a retrospective study of the patients who underwent orthognathic surgery at the Pusan National University Dental Hospital from December 2017 to August 2018. All the patients were analyzed through both CSP and VSP, and all the surgical stents were fabricated through manual and three-dimensional (3D) printing. The predictor variables were the planning method (CSP vs. VSP) and the surgery type (group I: Le Fort I osteotomy + bilateral sagittal split osteotomy [LFI+BSSO] or group II: only bilateral sagittal split osteotomy [BSSO]), and the outcomes were the time and cost. The results were analyzed using the paired t test. Results: Thirty patients (12 females, 18 males) met the inclusion criteria, and 17 patients were excluded from the study due to missing or incomplete data. There were 20 group I patients (LFI+BSSO regardless of genioplasty) and 10 group II patients (BSSO regardless of genioplasty). The average time of CSP for group I was 385 ± 7.8 min, and that for group II was 195 ± 8.33 min. The time reduction rate of VSP compared with CSP was 62.8% in group I and 41.5% in group II. On the other hand, there was no statistically significant cost reduction. Conclusions: The time investment in VSP in this study was significantly smaller than that in CSP, and the difference was greater in group I than in group II.

Purpose : This study assessed the effects of transcranial direct current stimulation (tDCS) on balance, fall efficacy, and fall-related fitness in stroke patients, using a cohort of 30 stroke patients divided into two groups. Methods : The experimental group (was given transcranial direct current stimulation in a virtual reality program) and the control group was given false tDCS in virtual reality. there were 15 patients in each group, receiving appropriate treatment over 30 sessions (30 minutes per session per week over a six-week period). In order to assess the change in balance before and after the intervention, the Berg Balance scale was utilized. Fall efficacy was evaluated using the Korean Falls Efficacy Scale for the Elderly (FES-K), The following exercises were performed by patients to assess fall-related fitness : sitting down in a chair and standing up : walking a 244 cm round= trip, and standing on one foot. Results : After the intervention, the experimental group exhibited significantly increased fall efficacy and fall-related fitness, while the control group exhibited no change. These findings suggest that tDCS has positive effects on balance, fall efficacy, and fall-related fitness in stroke patients. Conclusion : Using tDCS as an intervention would bring positive effects on balance, fall efficacy, and fall-related fitness in stroke patients undergoing rehabilitation.

In recent years, medical and health care fields have attracted attention for virtual reality (VR) applications. VR technology is emerging as a healthcare specialist and psychotherapy alternative to cope with the increase in the demand for the treatment of conditions such as psychological diseases caused by old age and stress. Using VR, virtual patients or organs can be trained, and the medical staff can plan and pre-test before surgeries. The use of VR technology for psychotherapy and rehabilitation of one-to-one, face-to-face treatment allows a single physician to respond to multiple health care needs.

The purpose of this study was to investigate the effects of a virtual reality rehabilitation program on upper limb function, cognition, and activities of daily living in stroke patients. Among the 25 participants in the program, it was randomly classified 13 experimental group and 12 control group. Rehabilitation training was applied 3 times a week and general occupational therapy 2 times a week using virtual reality rehabilitation training equipment in the experimental group, and general occupational therapy was performed 5 times a week, 30 minutes per session in the control group. As a result of the virtual reality rehabilitation program, cognitive function increased by 3.39 points in the experiment group, The control group who received only general occupational therapy increased by 1.5 points. As for the upper limb function, the average of the experimental group subjected to the virtual reality rehabilitation program increased by 4.84 points The control group who received only general occupational therapy increased by 1.34 points. As for activities of daily living, the average of the experimental group that conducted the virtual reality rehabilitation program increased by 20.38 points, The control group who received only general occupational therapy increased by 7.61 points. This result show that the virtual reality program has an effect on upper limb function, cognition, and activities of daily living of stroke patients.

This paper presents the preliminary study of an interactive rehabilitation support system for both dementia patients and their caregivers, the goal of which is to improve the quality of life(QOL) of the patients suffering from dementia through virtual interaction. To achieve the virtual interaction, three kinds of recognition modules for speech, facial image and pen-mouse gesture are studied. The results of both practical tests and questionnaire surveys show that the proposed system had to be further improved, especially in both speech recognition and user interface for real-world applications. The surveys also revealed that the pen-mouse gesture recognition, as one of possible interactive aids, show us a probability to support weakness of speech recognition.

In this study, 46 patients from a local hemodialysis center were enrolled to assess the effects of a self-motivated virtual reality (VR) exercise program on the heart rate variability and quality of life control in hemodialysis patients. The VR group (n = 23) completed a VR exercise program, where the subjects performed the exercise 40 min per session, 3 sessions per week, for 8weeks. After the exercise program, the heart rate variability and quality of life were measured. The VR group showed significant improvement in the heart rate variability and quality of life. The self-motivated VR exercise program provided both the role of supervisor as well as feedback, which is important for hemodialysis patients.Therefore, a self-motivated VR exercise program may be a useful tool for improving the psychosocial function in chronic disease patients undergoing hemodialysis.

PURPOSE. To integrate extra-oral facial scanning information with CAD/CAM complete dentures to immediately rehabilitate terminal dentition. MATERIALS AND METHODS. Ten patients with terminal dentition scheduled for total extraction and immediate denture placement were recruited for this study. The patients were submitted to a facial scanning procedure using the in-office PritiMirror scanner with bite registration records in-situ. Definitive stone cast models and bite records were subsequently submitted to a lab scanning procedure using the lab scanner (iSeries DWOS; Dental Wings). The scanned models were used to create a virtual teeth setup of a complete denture. Using the intra-oral bite records as a reference, the virtual setup was incorporated in the facial scan thereby facilitating a virtual clinical evaluation (teeth try-in) phase. After applying necessary adjustments, the virtual setup was submitted to a CAM procedure where a 5-axis industrial milling machine (M7 CNC; Darton AG General) was used to fabricate a full-milled PMMA immediate provisional prosthesis. RESULTS. Total extractions were performed, the dentures were immediately inserted, and subjective clinical fit was evaluated. The immediate provisional prostheses were inserted and clinical fit, occlusion/articulation, and esthetics were subjectively assessed; the results were deemed satisfactory. All provisional prostheses remained three months in function with no notable technical complications. CONCLUSION. Ten patients with terminal dentition were treated using a complete digital approach to fabricate complete dentures using CAD/CAM technology. The proposed technique has the potential to accelerate the rehabilitation procedure starting from immediate denture to final implant-supported prosthesis leading to more predictable functional and aesthetics outcomes.

By utilizing 3D image data from oral and facial scans, virtual patients can be created, allowing clinicians to accurately assess the occlusal plane and the aesthetic position and form of anterior teeth in relation to facial scan data. This integration enhances the predictability of aesthetic prosthetic treatments, reduces the potential for occlusal interferences and adjustments, and facilitates effective communication with patients during the diagnostic process. In this case report, a patient with skeletal Class III malocclusion had both oral and facial scans to generate a virtual patient during the diagnostic phase. Based on this virtual model, prostheses were designed and fabricated, resulting in an efficient and clinically satisfactory outcome both aesthetically and functionally.
