① 소성수축 균열
시멘트-페이스트는 경화할 때, 절대체적의 1%정도가 감소하게 된다. 이에 따라 소성상태에 있는 콘크리트의 체적이 감소하게 되는데, 이를 소성수축이라고 하며 콘크리트에 부분적으로 인장력을 유발시키는 원인이 된다. 특히, 타설 후 외기에 접하는 콘크리트 표면으로부터 수분

The Committee also required that banks conduct stress tests that consider the downward migration of their credit portfolios in a recession.

Cost of Equity
The cost of equity is a key ingredient of every discounted cash flow model. It is difficult to estimate because it is an implicit cost and can vary widely across different investors in the same company.
① Risk Free Rate
There can be no default risk, which generally implies that the security has to be issued by a government. Note, though,
estimated to be 16% by 2020 and 38% by 2050, resulting in an old-age dependency ratio of 70% in 2050(NSO, 2007). With population ageing, demand for long-term care has increased. But family structure has also changed, and the proportion of the elderly living with adult children has decreased to 38% in 2004. Availability of informal or family care givers diminishes as women’s labor participation
1. introduction
Consolidation is a process by which soils decrease in volume. It occurs when stress is applied to a soil that causes the soil particles to pack together more tightly, therefore reducing its bulk volume.
When this occurs in a soil that is saturated with water, water will be squeezed out of the soil. The magnitude of consolidation can be predicted by many differe
When this occurs in a soil that is saturated with water, water will be squeezed out of the soil. The magnitude of consolidation can be predicted by many different methods. In the Classical Method, developed by Karl von Terzaghi, soils are tested with an oedometer test to determine their compression index. This can be used to predict the amount of consolidation. Consolidation is the removal of wat
