Assessing Computer-Assisted Education for Non-hospitalized Children with Learning Disabilities in Al Wakrah Hospital Child Development Center, Hamad Medical Corporation (HMC)

Rodson Damian — 2024-11-18

Computer-assisted education technologies are commonly being used nowadays by Hamad Medical Corporation (HMC)'s pediatric multi-disciplinary rehabilitation team to promote learning and development of cognitive, sensory and motor skills for children with disabilities. Multi-disciplinary team services are delivered through individually tailored care plans aimed at developing each child's level of function and their quality of life. However, researches have shown that use of this advance technology comes with opportunities and challenges for both clinicians and patients, specifically non-hospitalized children with learning disabilities. With the intent of maximizing positive outcomes of the devices and its applications used, the researchers would like to gain insight on the selection and use of computer-assisted education technologies for non-hospitalized children with learning disabilities in HMC. The study will utilize mixed method sequential explanatory design to depict of the current practice in the use of computer-assisted education technologies by health professionals in their management of non-hospitalized children with learning disabilities. An adopted descriptive survey questionnaire tool and a qualitative phenomenological approach through individual interview will be conducted to gather data in this study. Responses will be analyzed using descriptive and inferential statistics to reveal what devices and applications are currently used in HMC for educating children with learning disabilities and what factors affect the use of computer-assisted education applications by these health professionals. Results of this study may serve as reference for health professionals, administrators and future researchers in developing strategies, frameworks and tools on technology selection and usage for their current services.

Influence of Deep Cryogenic Treatment on Fatigue Strength of 100Cr6 Bearing Steel

The objective of the study was to assess the impact of cryogenic treatment on the augmentation of fatigue strength in 100Cr6 steel bearings. The chilling process of a material to -185°C is known as cryogenic treatment, and it improves the material's mechanical as well as physical characteristics. This study aimed to investigate the impact of cryogenic treatment on the dimensional stability enhancement of 100Cr6 bearing steel utilizing DCT (deep cryogenic treatment) at -185°C. The dimensional stability has improved by 13.77 percent as a result of DTC in comparison to conventional heat treatment (CHT). The microstructural investigation reveals that the improvement in dimensional stability is because of the conversion of residual austenite into martensite, as well as the precipitation and dispersion of carbides resulting from the cryogenic treatment. The results of the DSC (Differential Scanning Calorimetry) research performed on the bearing steel samples indicate that the DCT mostly promotes martensite instability by triggering carbon clustering as well as transition carbide precipitation. The DTC showed a higher enhancement in dimensional stability than standard heat treatment because of the more homogenized distribution of carbide and the remaining austenite removal.
