Sulfur Dioxide(SO2)
The release of SO2 to the atmosphere is the primary cause of acid rain in the world.
Fossil fuel combustion at electric power-generating plants accounts for about70% of
the emissions.
Coal, Oil, and all other fossil fuels naturally
contain some sulfur.
Volcanic eruptions are another more localized natural source of SO2
SO2 + OH. HSO3.

1-3. 최적 압축비 이상으로 증가할 때 오히려 크랭크 축으로 전달되는 torque가 감소하는 이유 ?
압축비를 증가시킴으로써 엔진의 효율을 상승시킬 수 있다. 그러나 압축비를 무한정 높이지 못하는 원인들이 있는데 가솔린 엔진에서 압축비 제한의 가장 주요한 요인은 knocking이다.

Ⅰ. Introduction
1. Study background and objectives
Recently, due to environmental pollution and climate change, attention to environment is more growing than ever. Especially, buildings form 40% of energy and resource consumption, 30-40% of carbon dioxide emission, 20-25% of waste discharge, 17% of water consumption, and 25% of wood consumption, so buildings are mainly responsible for

Professor Hall...
...our economy is every bit as fragile
as the environment.
Perhaps you should keep that in mind
before making sensationalist claims.
Well, the last chunk of ice
that broke off...
...was about the size of Rhode Island.
Some people might call that
pretty sensational.

environment. In the early seventies and eighties there were people and even scientist who preach otherwise, but today the negative effects are showing. The earth is warming up and climates are changing. There are parts in the world were there be more rain and sunshine and others parts will be come dryer then they already are. Another negative effect is that the ozone layer is getting thinner whic
environment such as Reproductive energy wind power generation and solar heat power generation. Also, environment-friendly technologies- water treatment tech and air pollution control tech- apply to all business. Besides, Siemens considers efficiency of energy technology. It evolves complex fire power plant, driving system for industry, high voltage direct current (HVDC) and so on.

■ Objectives of Defense-in-Depth
• To compensate for potential human and component
failures
• To maintain the effectiveness of the barriers by averting
damage to the facilities and to the barriers themselves
• To protect the public and the environment from harm in
the event that those barriers are not fully effective
■ Strategy of
