In-depth analyses of post-corrosion mechanical properties and architecture of open cell iron foams with hollow struts as absorbable bone scaffolds were carried out. Variations in the architectural features of the foams after 14 days of immersion in a Hanks' solution were investigated using micro-computed tomography and scanning electron microscope images. Finite element Kelvin foam model was developed, and the numerical modeling and experimental results were compared against each other. It was observed that the iron foam samples were mostly corroded in the periphery regions. Except for quasi-elastic gradient, other mechanical properties (i.e. compressive strength, yield strength and energy absorbability) decreased monotonically with immersion time. Presence of adherent corrosion products enhanced the load-bearing capacity of the open cell iron foams at small strains. The finite element prediction for the quasi-elastic response of the 14-day corroded foam was in an agreement with the experimental results. This study highlights the importance of considering corrosion mechanism when designing absorbable scaffolds; this is indispensable to offer desirable mechanical properties in porous materials during degradation in a biological environment.
Eldercare workers' turnover intentions have caused serious concern given their high demand and pivotal role in ensuring elderly individuals' well-being. This systematic review examined the main factors of eldercare employees' turnover intentions with the purpose of identifying gaps and structure a novel human resource (HR) approach framework for eldercare social enterprises through a global literature review and realistic conclusions. A total of 29 publications appeared between 2015 and 2021 were digitally extracted from six databases and are extensively discussed in this review. Resultantly, eldercare workers' turnover intentions were positively impacted by job burnout, low job motivation, and restricted job autonomy. The findings of this study correspond to those of past literature, which highlighted the necessity of thoroughly examining eldercare worker retention practices from an organisational (HR) perspective. Furthermore, the current study outlines the factors influencing eldercare workers' turnover intentions as well as determine proper HR approaches to mitigate employee turnover issues among eldercare workers for organisational sustainability.
The study seeks to explore the perception of international patients on Malaysia as a medical tourism destination country, as well as overall patient satisfaction, perceived value and future intention for repeat treatment and services.
