Problem of
original process
There exists under ground Pit as a previous
car-press factory before present establishment.
Moisture resulted from inner underground pit goes up to the factory and results serious faulty of semiconductor component !
Previous solution
Install ventilation fan and emit inner humid air
so that solve the problem.
New solution
Sim

2) Exposure
In the stable air, expose the film
for 8~15 seconds
3) Develop
Developer(60s) → Water(2min)
→ Bleaching Agent (5min)
→ Washing(5~10min) → Drying
the dimensions of each grit chamber:
Assuming width-to-depth ratio = 1: 1 , depth = 2 m
a. Width = 1 X 2 (m) = 2m
b. Length = volume/ (width*depth) = 12.996 / (2 X 2) = 3.25 m
Determining the detention time at average flow
Detention time = 12.996 M3 / 0.03610 M3/s = 6 min
Determining the air supply requirement (assume: Air supply per unit of length = 0.2 M3/m
Two Sources of body water gain
- internal production : Water produced from the oxidation of organic nutrients
- ingestion : water ingested in liquids and foods
Four sites that lose water
- skin, respiratory air ways, gastrointestinal tract, and urinary tract
- Menstrual flow (in women)
The body gains sodium and chloride by ingestion and loses them via the skin (in sweat
air conditioner with silver nano coating to their inner surfaces for an overall anti-bacterial and anti-fungal effect. As air circulates, the coated surfaces contact with the silver ions which can resist any airborne bacteria, which in turn suppress the respiration of bacteria, adversely affects bacteria's cellular metabolism and inhibits cell growth.

(1) Poor road conditions
-> Not sensitive about max. speed
(2) Indian consumer
- price-sensitive
- expansion of the middle class
- design
1. Economic growth
-> Consumption Increase
2. Better social infra. (road)

allergen이 적어도 두 개 이상의 IgE와 만나면 mast cell은 granule을 방출한다. 여기서 histamine이 중요한데 H1 수용체가 early phase reaction-점액분비, vasodilation, bronchospasm-과 연관 있기 때문이다. mast cell은 이와 동시에 leukotriene, IL-4, IL-5를 합성한다. 이들의 기능은 다
air pollution, threat resident’s health, residential environment problem and sanitary problem are plenty of externalities to which china is not responding appropriately or can’t have the ability to react.
Next, on the assumption that material flow cycle is an arranged casual relationship, we can see that plenty of externalities are finally the results of the output and the connected circums
