(a)有一坋壤士K=0.65cm/h,=16.7cm，最大有效含水量為0.48，初始土壤 水分飽和度為0.3(注意:含水量與飽和度不同),當發生降雨時,假設降兩 強度不變,分別為2cm/hr與4cm/hr，從降雨開始地表發生積水或逕流的時間分別為何(所謂的Pondingtime)?(10%)

(1)試估算此新開發區域排水之尖峰流量:(10%)

(2)說明做此計算之假設為何?(5%)

4. 某上游集水區退水段流量Q(t)可利用退水曲線方程式描述如下: 其中Q0為t0時刻的流量(1)試利用線性水庫假設推導上式。(10%)；(2)其中參數 k可能單位為何?k值大小主要受到集水區的哪些特性影管?(5%)

5.請利用下表建立1小時延時所形成的單位歷線U(1，t)(15%)

(b)假設土地利用為未受人為活動干擾的草地,試簡述K與△θ值的大小如何影響 SCSMethod 中的CN值的大小,較高的K會對應到較高還是低的CN值?較 低的△θ值會對應到較高還是低的CN值?為何?(10%)

(a) Please identify what business processes need to be substantially revised/enhanced or what new business processes need to be developed, when a sharing economy platform plans to move from non-money-based to money- based.(13%)

(b) The movement from non-money-based to money-based should also trigger discussions of whether the IT strategy of the platform needs to be adjusted. What recommendations will you suggest to the sharing economy platform about its IT strategy when the sharing economy platform plans to move from non- money-based to money-based? (13%)

(a) In a digital market, will information asymmetry between consu umers and suppliers be reduced or intensified? What are the business implications of such change of infornation asymmetry (either reduction or intensifying) in digital markets? (12%)

(b) Some research studies indicate that "in a digital market, the switching cost (i.e..the cost of switching from one supplier to another supplier) of consumers can either be increased or be decreased, depending on the nature of the product or service being sold." Please identify the characteristics of products/services that will have higher consumers' switching costs in the digital markets than in the traditional markets. Please also identify the characteristics of products/services whose consumers' switching costs will decrease when these products/services are sold in digital markets. (12%)
