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
~ 2000 Years Ago – Sulfide nanocrystals used by Greeks and Romans to dye hair
~ 1000 Years Ago (Middle Ages) – Gold nanoparticles of different sizes used to produce different colors in stained glass windows
1959 – “There is plenty of room at the bottom” by R. Feynman
1974 – “Nanotechnology” - Taniguchi uses the term nanotechnology for the first time

3. Enhanced counterparty credit risk management
requirements
a comprehensive stress testing program for
counterparty credit risk
an independent risk control unit
of the most destabilising elements of the crisis has been the procyclical amplification of financial shocks throughout the banking system, financial markets and the broader economy. The tendency of market participants to behave in a procyclical manner has been amplified through a variety of channels, including through accounting standards for both mark-to-market assets and held-to-maturity loans,
Design a pipeline system to carry 0.2m3/s of oil from an oil field to a refinery located 1000km away. The elevation of the refinery is 50m higher than that of the oil field.
Estimate the cost to build the pipeline and the pumping stations.

⑴ What is biofilter?
- Technology processed gas pollutants by biological methods, immobilized on porous carrier by the metabolic activity of microorganisms decompose into harmless substances
- Depending on the configuration and operation of the device, it can classify as Biofilter, Biological Trikling Filter, Bioscrubber and Air Lift Bioreactor
Example of use of Biof
II. What Are Credit Derivatives?
Derivatives are defined as the exchange or contract which has economic values deriving from the reference assets or index. According to their types, there are overall forward, future, option, and swap. Derivatives are the financial derivatives, which are enabled to trade in the market while consisting of separating the credit risk only to the holder of basic p
