ammonia. In principle the chemistry of ammonia synthesis was simple but the execution was difficult because high temperatures and very high pressures were needed to produce enough quantities of ammonia to make the process economical. Habersucceeded in developing an ammonia synthesis process that worked in the laboratory in 1909. Initially, Haber used osmium or uranium as a catalyst to speed up
Ⅰ. 기업경쟁력평가
1. 핵심성공요인들과 성과측정치들에 의한 경쟁력 평가의 실무적 문제점
기업의 경쟁력을 평가함에 있어서 그 기업의 핵심성공요인들과 성과측정치들을 연결시키는 필요성에 대해서는 널리 인식되고 있다. 관리회계와 전략회계 분야의 많은 연구에서는 많은 의사결정분야에
exceeds 210 degrees Fahrenheit carbon dioxide production increases with little production of methane. The thermogenic production of methane does not exceed the production of carbon dioxide in high volatile high ranks of coal until the temperature is about 250 degrees Fahrenheit. The maximum generation of methane in bituminous coals occurs at around 300 degrees Fahrenheit (Rightmire, 1984).
economic benefits but also Preventive Maintenance has a benefit such as improving the experience of building user or making the work of the maintenance department more manageable. Ultimately Preventive Maintenance purpose is to give a great benefit to company by reducing the cost and improving the built environment to increases workers' productivities.

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
