Abstract
Bioethanol is one of the alternative sources of oil resources which received attention with biodiesel. Many countries produce bioethanol from food sources such as corn and sugarcane, but it causes food-energy conflicts and farmland problem. So it needs to focus on new biomass which is sustainable, renewable, cost-effective and do not occurred any conflicts. Algae are one of the bioma
5.2 Drug Delivery System
5.2.1 Advantage of Nano-drug delivery system
By diagnosis, and for treatment, we need enhanced drug delivery system. Drug delivery system of these days is just eat and let it flow through the body. It is not good at efficiency. Because the digestive system sometimes digest and remove the drug before it reaches to the target.
For enhancing the efficiency of drug
Let's see the process flow of cellulosic ethanol which we are interested in(Figure 1). At the upstream, biomass harvest undergoes a pretreatment and cellulose hydrolysis by enzymes and then fermented to ethanol through the points. The initial contract for each course are as follows.

Q = (360gmol/s)X(0.040kJ/gmol·s)X(1400°C−900°C)
= 7200kJ/s
Heat exchanger cool that gas to 25℃, and it condense water.
Q1=(9.5gmol/s)(29.1kJ/gmol)+(9.5gmol/s)(24.1kJ/gmol)
+(90.5gmol/s)(-22.9kJ/gmol)
+ (20.5gmol/s)(-37.4kJ/gmol)
= - 3344kJ/s
Q2(latent heat of water) =(9.5gmol/s)(-40kJ/gmol)
= - 380kJ/s
Q1+Q2 = - 3704kJ/s
The heat removal rate in t
2-1. What segment(s) is Saturn now targeting?
(before)
→ 20-40s of the middle class
Saturn captured that customer prefer small-car costs low amount of fuel consumed because of inflation, raising of fuel cost and youth, women dissatisfied with services, quality of car. They noticed their target segmentation(20-40s of middle class) is feeling stress of services, prices,. So, Saturn choose tha

1. SCM(Supply Chain Management) Innovation
Hyundai Motor Company has pushed ahead an innovation over SCM sector from early 2000. The company built VAATZ system to promote smooth communication with subcontractor. It also started the APS(Advanced Planning & Scheduling) project of Sales and Production Planning Section, which was a toehold for SCM. Enterprise Process Innovation(PI) was be
1. Who is Kuznets?
Kuznets, born in Russia is an American economist He was an authority on national income theory and national income statistics and was awarded Nobel economics prize in 1971 by contributing numerical analysis in economics. His principal work was estimating national income and comparing types of economic growth of each countries. These achievement has been
High-temperature decomposition
High-temperature splitting of water occurs at about 3000 °C. At this temperature, 10% of the water is decomposed and the remaining 90% can be recycled. To reduce the temperature, other processes for high temperature splitting of water have been suggested:
▸Thermo-chemical cycles.
▸Hybrid systems coupling thermal decomposition and electrolytic
