drainage systems were often needed to remove excess water.
Until the late nineteenth century, Finland's isolation required that most farmers concentrate on producing grains to meet the country's basic food needs. In the fall, farmers planted rye; in the spring, southern and central farmers started oats, while northern farmers seeded barley. Farms also grew small quantities of potatoes, other roo
system was inserted between the chest tube and chest canister.
Acute bleeding was mimicked by periodic infusion of blood.
The amount of blood drained from each chest cavity was recorded every 15 min for 2 h without tube manipulations.
After completion of the procedure, all residual blood and clots in each chest cavity were assessed
Significantly improved drainage compared to a standa
2. The Necessity of sustainability
The recent research show that it demands some expenses in the first stage. But when they pass through some point, it will bring the achievements of corporation.
First, the sustainability is a flow in this period that can not be ignored and the essential factor to compete in this field. The playstaion in Sony lost more than 200 million dollars when the Cadmium,

응급실의 특성상 다양한 환자를 관찰할 수 있는 기회가 많았다. 그중 응급실 4일차 실습 중 호흡곤란을 호소하시며 기흉으로 한 환자분이 내원하셨다. 의사선생님들이 이 정도로 커졌는데 응급차를 타지 않고 걸어오신 경우는 처음이라고 하였다. 응급상황으로 내원하자마자 외상 소생실에서

에어컨과 같은 냉방 시스템이 없던 과거에는 어떻게 더위를 식혔을까?
신라시대 사람들은 더위를 식히기 위해 석빙고를 이용했었다.
석빙고에 얼음을 저장해 놓은 후 이를 이용하여 더위를 식힌 것이었다.
하지만 현재는 눈부신 과학기술 발전에 힘입어 선풍기, 에어컨 등의
Tidal stream generators (TSGs) make use of the kinetic energy of moving water to power turbines, in a similar way to wind turbines that use moving air.
A TSG is a machine that extracts energy from moving masses of water, or tides.
Energy can be captured from tidal streams using two methods,
Tidal fences and Tidal turbines.
Dynamic tidal power or DTP is a new an

The Brazilian Federation is the "indissoluble union" of three distinct political entities: the States, the Municipalities and the Federal District.
Brazil is a federation composed of twenty-six States, one federal district (which contains the capital city, Brasília) and municipalities. States have autonomous administrations, collect their own taxes and receive a share of taxe
