Water stress results from an imbalance between water use and water resources. The water stress indicator in this map measures the proportion of water withdrawal with respect to total renewable resources. It is a criticality ratio, which implies that water stress depends on the variability of resources. Water stress causes deterioration of fresh water resources in terms of quantity (aquifer over-e
Waters’ balance sheets show that its debt ratio is high. The debt ratio was 0.925 in 2010, 0.896 in 2009, and 0.995 in 2008. Most of its liabilities are short-run debt. This short-run debt seems to be used in investing activities. According to cash flow statements from 2003 to 2010, most cash was used in investing activities.

ratio of wet harvest and dry harvest is possible with some method. That is, we can fix the ratio with 70% of wet harvest regardless of the length of term (either in short-term or in long-term).

In this assumption,
II. 실험방법 및 과정
1. 각 재료(시멘트, 물, 모래, 자갈)의 배합량을 확인한다.
2. 각 재료를 필요한 만큼 저울로 측정하며 조교의 확인을 받은 후 물을 섞지 않은 상태에서 배합용 판 위에서 섞는다. (dry mix).
3. 물을 반쯤 붓고 배합한다.
4. 남은 물을 조금씩 넣으며 모두 배합한다.
5. 배합이 완료
