Water mist was sprayed on small compartment areas filled with smoke that formed from two different combustibles. The water-mist injection pressure and time were varied, and changes in the light extinction coefficient were measured over time. The smoke removal effect was analyzed with a light sensing smoke meter in different experimental conditions. Using the meter, the changes in smoke density were converted to changes in DC voltage over time to obtain the changes in the light extinction coefficient. The water mist was more effective in eliminating the smoke formed from glowing compared to flaming combustion. The smoke removal effect was significantly better with greater injection pressure and injection time.

In the event of a building fire, it is important to control the smoke generated to ensure the safe evacuation of occupants. A natural smoke ventilator should be installed to exhaust the fire smoke in accordance with the Korean building Act and Code. On the other hand, the present law does not specify the contents regarding natural smoke ventilators sufficiently. The problems that occur in various parts, such as the installation target, installation location, free area, and the control and maintenance of natural smoke ventilators need to be solved. In this study, the problem of the current system was examined through domestic and foreign standards, preliminary research, and field investigations. In addition, suggestions for improvement are provided.

The spice phenomenon therapy is to adhibit aromatic herbs or materials to the human body or clothing, for the purpose of preventing and treating diseases. Mankind found the fire, and found that some plants and trees give off smoke when they are burning. Then, they found that some of aromatic substances had certain actions after being absorbed through the respiratory organ, which was the beginning of the spice phenomenon therapy. The spice phenomenon therapy is effective to relieve the exterior syndrome, to eliminate dampness, to regulate Qi flow, and to induce resuscitation. It has two actions. One is that the aromas that permeated the body, refreshes the mind, stimulates the appetite, strengthens the spleen and the stomach, and makes a relaxing sleep. The other is that the aromatic substances, absorbed into the human body, have pharmacological actions. The volatile aromatic substances have various pharmacological actions such as stimulating cranial nerves, dilating cardiac blood vessels, promoting gastric secretion, relaxing and sleep-inducing. It has been proved that the spice phenomenon therapy is anti-inflammatory and anti-microbial and is effective to dilate cerebral blood vessels and to ease the pain. It is expected to be studied more aggressively.
