다. Amino Acid의 Titration과 pH buffer 작용
Amino Acid를 NaOH와 같은 염기로 Titration을 하여 얻어지는 Titration Curve는 적정하는 Amino Acid의 pH buffer 작용을 잘 설명해 준다.
즉 Amino Acid의 Carboxyl기는 Weak Acid이므로 NaOH-와 같은 Strong Base와 반응하면 일정한 pH 범위 내에서 큰 pH 변화를 일으키지 않는 pH Buffer 작용을 한

2.3 Methods used for restoration
Firstly, a water purification system using gravel contact oxidation process was installed to clean the water. The system located in Young-dong 2 gyo was the first to utilize the gravel contact oxidation process in Korea. It uses a media like gravel and artificially maximize the natural purification process like precipitation, absorption and decomposition by
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. In 2010, for example, net cash flow provided by operating activities
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
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). Although wet harvest is more beneficial to farmers so every farmer will prefer water harvest to dry harvest, we can avoid the increase of ratio by giving some incentives to dry harvest. In this assumption,
