potential drug delivery carriers to tissues throughout the body. Yet passing the BBB is particularly difficult. The proper design of such engineered ‘nanocarriers’ becomes very important in transversing the impermeable membranes to facilitate drug delivery. At the same time, it is also required to retain the drug stability and ensure that early degradation of drugs from the nanocarriers does
2) Satir’s Growth model
Satir(1972) suggested that self-esteem, communication, and family rules would determine personal and familial functions. Especially, she emphasized self-esteem and self-worth for basic and therapeutic concepts in this model. Self-esteem is the belief about self by evaluating own attributes. When people can satisfy their desires by using their own resources, and feel tha
Tidal stream generators (TSGs) make use of the kinetic energy of moving water to power turbines, in a similar way to wind turbines that use moving air.
A TSG is a machine that extracts energy from moving masses of water, or tides.
Energy can be captured from tidal streams using two methods,
Tidal fences and Tidal turbines.
Dynamic tidal power or DTP is a new an

Responsibility: all participants, including policymakers and program designers, are responsible for the security of information systems and networks.
Response: Participants should act in a timely and cooperative manner to prevent, detect and respond to security incidents. Where permissible, this may involve cross-b
- GDP per capital : Korea
In 1981, Korea's GDP per capital was about $ 10,000 but it increased continuously. It's already over the $ 20.000 and it is predicted that Korea would keep grow in the future.
- Major industry : Korea
The value of the Agriculture sector accounted for 3% of GDP. The agriculture sector of Korea was mainly based on crop production, animal husbandry,
