films have similar growth vertical orientations. AFM images showed the grain scale and roughness of thin film respectively. It can be argued that wrutzite structure of ZnO was formed using XRD Study. Photoluminescence spectra excited by a He-Cd laser atroomtemperature showed the green luminescence at approximately 500~550nm. The GZO thin film has the best electrical properties among all samples
atroomtemperature.
3. Results and Discussion
3.1 Structural Properties
Fig.1. presents cross-sectional FE-SEM images of all the samples. For all the samples, the columnar shaped ZnO grains grown normal to the substrate surface are clearly seen. When MZO and GZO films are deposited after ZnO films, it seems that similar columnar shaped grains are formed. It can indicate if the same co
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
of progressive digital convergence knowledge can be severe. Digital convergence is not only tool of digitalized life but also tool of survival.
(3) New Business Environment
Digital convergence will changes business environment. These changes have crisis and opportunity, both two sides.
Crisis is originated at uncertainty and deepened competition. Integration of device will be occur limit
