1. Background
Scent: Odor
The sense of smell gives rise to the perception of odors, mediated by the olfactory nerve. The olfactory receptor (OR) cells are neurons present in the olfactory epithelium, a small patch of tissue in back of the nasal cavity. There are millions of olfactory receptor neurons that act as sensory signaling cells. Each neuron has cilia in direct contact with air. The
(Definition of an air transport Hub)
-Just simply, a hub airport is a center airport.
-And from this main airport, all small, medium sized airports are linked.
-It acts as switching centers so it intermediates flows between multiple origins and multiple destinations.
-Airline companies first gather both passengers and cargos to this hub airport and from there, they are re-gathered and later

과거와 달리 최근 지구환경변화문제에 대한 인식의 폭이 커지면서 항만도 환경오염의 발원지라는 인식이 확대되고 있다. 항만분야의 경우 국가별 탄소배출량 감소 계획에서 제외되어 있으나, 최근 EU를 중심으로 항공 및 해운에 대한 탄소배출량 규제 압력이 증가하고 있어 향후 항만 부문

Virtualization
One server could run only one application at a time
→ 10 to 20% of the capability of a typical server is used
Virtualization
: a framework of dividing the resources of a computer into
multiple execution environments
→ This significantly reduces energy use because only
fewer servers are needed
