Nanometer: one billionth of a meter
Nano-: prefix comes from the Greek word for ‘dwarf’
Chemical, physical, and biological properties that differ from those of their larger, or bulk counterparts
Nanotechnology: The National Nanotechnology Initiative(NNI)-> the science of materials and phenomena in the range of 1 to 100nm in diameter

1. Introduction
Despite the social concern about health, there are a lot of restrictions in 'heathy life' of women. The right of health for women doesn't include 'women' and even, their health is in the system which is hard for them to guarantee it by themselves. In this situation, it is an urgent issue to understand what is health for women and find out possible measures to solve it.
For th

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

Ⅰ. Introduction
1-1. Investigation assignments
In this report, we would like to discuss about necessity of integrated information system in restaurant industry. The report analyzed ‘토종 칼국수와 족발’ as a representative case of the absence of integrated information system. The report specifically points out problems caused by absence of integrated information system and sugg
Dissolved O2
2% of total O2 content in blood
Dissolved O2 is 0.3mL O2/100mL blood
[At normal PaO2(100mmHg)]

Not satisfy Oxygen demand of tissue
O2 Binding capacity
maximum O2 that can be combined with blood unit
volume of Hemoglobin
Most of O2 transported in blood, is decided by O2 binding capacity of Hemoglobin and concentration of erythrocyte. O2-Binding capacity is maximum
genes latus) are filled with PHB in their body. These PHBs have to be separated from microorganisms to make final product. To separate PHBs from biomass, they are extracted from biomass by using solvent. These PHB extracted solvent will experience washing and drying process. After that, PHB can be precipitated as white powder. Most commonly used solvent is Chloroform. After end of this extraction
