Granulomas (miscropic nodules), consisting particles, live and dead cells, and debris and could impair cellular and physiological (gas exchange) lung functions and give rise to fibrosis, more defined nodules, and other lesions.
Fibers are generally of more health hazard than other forms of particulates. It is well established that the pathogenicity of a fiber in the lungs directly correlates
nanotechnology, especially nanoparticles that can carry the drug molecules to the target safely.
5.2.2 Nanocarriers - Nanoparticles
Before starting with the functionalization of nanoparticles, it is important to keep in mind a range of useful properties we wish to have in any drug delivery across the BBB(Blood brain barrier). In this context, owing to their small size, customizable surfac
1. 나노 기술 (Nanotechnology)의 정의
10억분의 1m인 nm 크기에서 물질을 조작하는 기술
나노 기술(NT: nano- technologoy)이란 원자나 분자의 수준에서 물질들을 조작하고 만들어서 전혀 새로운 성질과 기능을 가진 소자나 시스템을 구현하는 기술을 통칭한다. 나노미터는 10-9미터, 즉 십억분의 1미터에

Regulation of IT Risk
In order to regulate the IT risk, governments work to address threat to computer crime. For example, representatives of 29 countries - including Canada, Japan and the U.S. – signed the Council of Europe Cybercrime convention in 2001. The convention deals with substantive and procedural cybercrime law. The substantive defines the following activities as crimina
