The road to publication can seem long and daunting. Further, access to published work is often limited to larger institutions that can afford expensive journal subscription fees. Gold open-access publications aimed to change the landscape of evidence-based science, allowing papers to be widely accessible without a subscription, often requiring an article processing fee paid by the author or institution. Regardless of the access model, reputable journals are expected to adhere to the publishing code of ethics and provide transparency in the peer review process. While the latter can significantly increase the length of processing time through multiple revisions, editors and peer reviewers provide expert opinions and valuable feedback, thereby safeguarding the integrity of the journal and the scientific process.

Client feedback is an integral part of the health care system’s quality and effectiveness. In health care operations, it is paramount as it serves as a vital tool for continuous improvement, ensuring patient-centric care delivery, and fostering trust and accountability within the health care system. Client feedback helps shape up new and existing policies and is, therefore, highly valued, considered, and acted upon. In health care institutions such as the Southern Philippines Medical Center (SPMC), incorporating client feedback into policy-making enhances health care operations and aligns services with patient needs and institutional goals. In SPMC, the Hospital Client Experience Survey is the primary feedback mechanism by which clients, both internal and external, can voice their opinions, concerns, and suggestions regarding its personnel, processes, and structure. Through directives from the Anti-Red Tape Authority (ARTA)1 and the Department of Health (DOH),2 SPMC uses the Hospital Client Experience Survey Tool (HCES) to enhance service delivery. Public Assistance and Complaints Desk (PACD) Officers conduct monthly surveys across 200 hospital areas. Each area expects 5 to 30 responses, based on a calculation by the HCES Online Report Generator (ORG). PACD officers actively engage staff within their designated areas, encouraging their participation in survey distribution per transaction and motivating clients to provide feedback during specified survey days. Highlighting the significance of these surveys, PACD Officers emphasize the invaluable insights gained from diverse client responses, which ultimately shape and validate the impact of service delivery initiatives within the hospital. At the end of each quarter, PACD officers analyze data using the HCES-ORG, collate comments and commendations, verify the accuracy of HCES results, and then post them for viewing by the different departments within the institution. Exceptional staff commendations are documented in the quarterly HCES results publication, prominently displayed within the hospital. These commendations contribute to individual performance evaluations. If a staff member receives negative feedback on the HCES form, their unit manager receives a photocopy of the form and may implement disciplinary action or enroll the staff in customer service seminars hosted by the Professional Education and Training Department (PETD). Consistent negative feedback over three consecutive months may trigger appropriate improvement plans or corrective actions among individual staff or even entire departments. The infographic displays the reports from the HCES for the first to the fourth quarters of 2023. Clients’ feedback comprises three domains: personnel, processes, and structures. Personnel covers attitude and character, processes involve system and organization, and structures include facilities and equipment. The feedback includes both positive and negative comments, with recommendations also identified. The HCES consists of statements rated on a scale from 1 (strongly disagree) to 5 (strongly agree). For this infographic, we computed the mean satisfaction scores for each domain and the proportion of clients who reported satisfaction with the service and timeliness of service they received. To summarize the recommendations from the HCES, we utilized the artificial intelligence (AI) chatbot-powered search engine Perplexity AI. We uploaded the recommendations in spreadsheet format and prompted Perplexity AI to "Summarize, in bullets, the recommendations into three categories: personnel, process, and structure," and then to "Count the times each of those summarized comments were mentioned in the file." We used the response of Perplexity AI to illustrate the results as a word cloud, with the sizes of the words in the cloud proportional to the frequency of mentions. In the HCES, the most frequently mentioned suggestion was to provide additional staff. Other suggestions included maintaining clean and functional restrooms, and improving overall cleanliness and sanitation. Infrastructure-related suggestions focused on better ventilation, air conditioning or fans, expanding wards and watchers’ areas, adding more hospital beds and chairs, ensuring a consistent water supply, and providing necessary diagnostic and therapeutic equipment and medicines. Process-related recommendations focused on reducing service delivery turnaround time, prioritizing senior citizens, PWD, and pregnant patients, improving billing and laboratory services, optimizing operation scheduling, and enhancing staff communication and coordination between and among offices. Personnel-related suggestions included improving staff interaction with patients, providing staff training, ensuring staff safety, and performing diligent patient checks. Client feedback helps SPMC retain positive responses, optimize health care delivery, and serve clients better through ongoing renovations, reorganizations, and transformations, affirming its vision of quality service.

A new diamond-based variable spring-mass model has been proposed in this study. It can realize the deformation simulation for different organs by changing the length of the springs, spring coefficient and initial angle. The virtual spring joined in the model is used to provide constraint and to avoid hyperelastic phenomenon when excessive force appears. It is also used for the calculation of force feedback in the deformation process. With the deformation force feedback algorithm, we calculated the deformation area of each layer through screening effective particles, and contacted the deformation area with the force. This simplified the force feedback algorithm of traditional spring-particle model. The deformation simulation was realized by the PHANTOM haptic interaction devices based on this model. The experimental results showed that the model had the advantage of simple structure and of being easy to implement. The deformation force feedback algorithm reduces the number of the deformation calculation, improves the real-time deformation and has a more realistic deformation effect.

Neural mass models are able to produce epileptic electroencephalogram (EEG) signals in different stages of seizures. The models play important roles in studying the mechanism analysis and control of epileptic seizures. In this study, the closed-loop feedback control was used to suppress the epileptic-form spikes in the neural mass models. It was expected to provide certain theory basis for the choice of stimulus position and parameter in the clinical treatment. With the influence of measurement noise taken into account, an unscented Kalman filter (UKF) was added to the feedback loop to estimate the system state and an UKF controller was constructed via the estimated state. The control action was imposed on the hyper-excitable population and all populations respectively in simulations. It was shown that both UKF control schemes suppressed the epileptic-form spikes in the model. However, the control energy needed in the latter scheme was less than that needed in the former one.

There is limited evidence regarding the use of virtual reality (VR) and interactive video gaming for improving arm function because there are few such commercial devices and little relevant research. However, evidence of the greater effectiveness of upper extremity VR training over that of conventional therapy after stroke has recently grown due to the adoption of various therapeutic devices. VR applications are novel and potent technologies for upper extremity rehabilitation after stroke because the interface technologies, augmented reality technologies, and various sensorimotor feedback techniques are rapidly advancing. Going forward, VR technology should be designed to provide the possibility of intense functional repetitive practice for patients. The combination of VR with robotic devices, neuromodulation, mirror therapy, and telerehabilitation may synergistically improve upper extremity function after stroke. In severely injured patients, robotic interfaces should be considered, the level of difficulty should be fitted appropriately to the severity of the deficits, and the fact that it is difficult to train patients repeatedly and effectively in a real-world environment should be considered. Further research should be conducted on the application of VR programs in larger populations, VR involving various training paradigms, VR at different exercise levels, and the long-term sustained effects of VR. In addition, synergistically enhanced effects of combining other treatments and feedback paradigms with well-designed interfaces should be investigated.

PURPOSE: The purpose of this study was to investigate the effect of self-postural control on foot pressure in subjects with forward head posture. METHODS: Forty-two healthy adults were recruited in this study. Participants were divided into two groups: The forward-head postural (FHP) group (craniovertebral angle<53°, n=22) and the control group (craniovertebral angle≥53°, n=20). In the FHP group, foot pressure was measured using three different standing postures: Comfortable standing posture (CSP), subjective neutral standing posture (SNSP), and neutral standing posture with visual feedback (NSP-VP). Each position was performed in random order. In the control group, foot pressure was measured only using the comfortable standing posture. RESULTS: With respect to CSP and SNSP, there was a significant difference on heel pressure between the two groups (p<0.05). Regarding NSP-VP, however, there was no significant differences on heel pressure between the two groups (p>0.05). CONCLUSION: We suggest that cervical posture control using visual feedback has a positive effect on the distribution of foot pressure in subjects with forward head posture.

OBJECTIVE: To determine stability parameters in clinical balance tests and posturography that can assess age-related changes in posture control sensitively METHOD: Thirty nine healthy elderly people over 60 years old and twenty young controls were recruited. Elderly people were subdivided into 3 groups by age (aged 60~69, 70~79, over 80). Subjects were evaluated with clinical balance tests and posturography. In posturography, center of pressure (COP) parameters were obtained as total path distance, sway area, mean frequency of sway in comfortable standing. Visual feedback system (VFS) was added to posturography and then subjects were asked to move their COP into the target circle on monitor with active movement on force plate. In VFS, time to get in the circle, total path of deviation, time in the circle were measured. RESULTS: Time in the circle assessed by posturography with VFS showed significant difference between age groups (p<0.05). Significant correlations between time in the circle and clinical balance tests were also found (p<0.01). CONCLUSION: A posturography with VFS was considered to have clinical usefulness in sensitive evaluation of age-related change of balance control in healthy elderly people.
