Background and Objectives: In 2013, the Singapore government reviewed and expanded the Senior Mobility Fund (SMF) to provide subsidy for assistive devices, including hearing aids (HA). While SMF has improved accessibility to HA, its impact on HA acquisition has not been determined. The study aims to elucidate the influence of SMF on HA acquisition and the relationship between financial funding and compliance to HA use.Subjects and Methods: Retrospective review of 643 patients seen between January 2017 to January 2018 at the earnose and throat specialist outpatient clinic, who were referred for a hearing aid evaluation. Of the 643 patients, 109 patients with baseline hearing handicap (HH) scores recorded, and no formal diagnosis of cognitive impairment were included. The patients were grouped according to SMF eligibility and clinical data were obtained.Results: The odds ratio for acquiring HA was significantly higher with SMF, regardless of HH scores. When looking at actual degree of hearing loss (DHL), HA uptake was significantly higher in the least severe of DHL categories. There is no relationship between SMF and compliance to HA use. However, HH score is positively correlated with data log in regression analyses.Conclusions: SMF appears to influence HA acquisition. Especially in financially funded patients with low self-perceived HH, the benefits of HA may be underappreciated given the few hours of HA use. Further studies are warranted to investigate the impact of financial funding on outcomes of HA users to help policy planners and clinicians be prudent in the utilization of SMF.
Hand Gesture Control for Human–Computer Interaction with Deep Learning

The use of gesture control has numerous advantages compared to the use of physical hardware. However, it has yet to gain popularity as most gesture control systems require extra sensors or depth cameras to detect or capture the movement of gestures before a meaningful signal can be triggered for corresponding course of action. This research proposes a method for a hand gesture control system with the use of an object detection algorithm, YOLOv3, combined with handcrafted rules to achieve dynamic gesture control on the computer. This project utilizes a single RGB camera for hand gesture recognition and localization. The dataset of all gestures used for training and its corresponding commands, are custom designed by the authors due to the lack of standard gestures specifi cally for human–computer interaction. Algorithms to integrate gesture commands with virtual mouse and keyboard input through the Pynput library in Python, were developed to handle commands such as mouse control, media control, and others. The mAP result of the YOLOv3 model obtained 96.68% accuracy based on testing result. The use of rule-based algorithms for gesture interpretation was successfully implemented to transform static gesture recognition into dynamic gesture.

Recently human adipose-derived stem cells (ASCs) have shown much therapeutic potential in regenerative medicine. However, fetal bovine serum (FBS)used in culturing human cells may give risk to viral and prion transmission as well as immune rejection. Human serum (HS) is a safer growth supplement in human cell culture but its effects have not been well established. Therefore the objectives of this study were to compare the effects of HS versus FBS on the proliferation and stemness gene expression of ASCs. ASCs were cultured for 5passages in medium supplemented with either 10% HS or 10% FBS. ASCs proliferation rate and viability were determined at every passage. Total RNA was extracted at passage 5 (P5) and quantitative PCR was carried out to determine the stemness gene expression level of SOX-2,Nanog3, BST-1, REX-1, ABCG2 and FGF-4. The results showed ASC cultured in 10% HS scored greater proliferation rates and viability compared to 10% FBS. ASCs proliferated significantly faster in 10% HS compared to 10% FBS at P2, P3, and P4 (p < 0.05). In quantitative gene expression analysis, ASCs cultured in 10% FBS showed a significant increase of BST-1, REX-1 and ABCG2 expression compared to 10% HS. In conclusion, HS promotes ASCs proliferation and viability but its ability to support the stemness property of ASCs was inferior to FBS.
Obstructive fibrinous pseudomembrane tracheitis after double-lumen tube intubation -a case report-

Background: Obstructive fibrinous pseudomembrane tracheitis (OFPT) is a rare complication of endotracheal intubation. Case: We describe the case of a 73-year-old woman who underwent short-term intubation for video-assisted thoracoscopic surgery and developed an acute life-threatening stridor two days after extubation. The patient required an emergency tracheostomy to maintain airway patency and a microscopic direct laryngoscopy procedure was performed thereafter with removal of the obstructive pseudomembrane. Subsequently, the patient also suffered a non-ST-elevation myocardial infarction. The patient successfully recovered, and the tracheostomy was subsequently decannulated two months later. Histological examination revealed mucosal ulcerations and inflammatory changes.Conclusions: OFPT is an uncommon cause of life-threatening airway obstruction after extubation that is not often recognized immediately but can usually be treated with early bronchoscopic intervention or microscopic direct laryngoscopy.

This study examined the effects of academic self-concept (internal factor) and maternal parenting behaviors (external factor) on academic delay of gratification (ADOG). Additionally, models predicting ADOG were compared between Korean and Malaysian children. The participants of this study were 100 Korean third graders and their mothers, and 100 Malaysian third graders and their mothers. The children completed the modified versions of the Academic Delay of Gratification Scale for Children, and Academic Self-Concept Questionnaire. The mothers completed the Parenting Attitude Test. Pearson's correlation tests, independent t-tests, and multiple regression analyses were conducted to test the research hypotheses. The results showed that Korean children reported higher ADOG and academic self-concept scores than that of Malaysian children. Moreover, academic self-concept was found to have a significant positive effect on ADOG among both Korean and Malaysian children. There was no significant gender difference in ADOG for both Korean and Malaysian children. However, the effects of maternal parenting behaviors on ADOG were only detected among the Malaysian children, particularly on Achievement Press. That is, only for the Malaysian children, maternal pressure about academic achievement was found to have a significant positive effect on ADOG. In conclusion, only academic self-concept was found to be a significant predictor explaining the variance in ADOG among Korean children. On the other hand, academic self-concept and maternal parenting behaviors were shown as significant predictors explaining the variance in ADOG among Malaysian children.
