Due to the dynamic and ephemeral nature of ubiquitous computing (ubicomp) environments, it is necessary that application software in ubicomp environments is situationaware (SA) and should be adaptable to both users' situation changes and the requirement changes. Reconfigurable Context-Sensitive Middleware (RCSM) has been developed to provide development and runtime support for SA software in ubicomp environments, but do not provide runtime support for on-demand context acquisition, action scheduling and dynamic reconfiguration of SA software, and development support that maximize the reusability. In this paper, the development and runtime support provided by RCSM have been substantially expanded to greatly simplify the development of situation-aware application software, and to achieve reusability and runtime reconfigurability simultaneously.

1 for ensuring that their final-year students were given the opportunity to respond to the increasing need in the health care system during these challenging times. We also commend these students for their willingness to join the workforce amidst rising fears and concerns of the COVID-19 pandemic, which shows they are ready for their lifelong call as frontline staff. The same opportunity was offered to final-year U.K. medical students through the interim Foundation Year (iFY) programme 2 before they formally started Foundation Year 1 (FY1), comparable to an internship, in August 2020. However, the accelerated graduation and deployment of the new physician cohort into the workforce has had negative consequences.
