  • For the purpose of fermentation control and edible period extension of lower salted Kimchi, the contents and compositions of pectic substances in Kimchi, by adding 2 percent salt and 0.4 percent sodium malate buffer(SMB), fermented at $20^{\circ}C$ were investigated. Edible period of SMB added chinese cabbage Kimchi was extended 40 hrs compared to that of control (added 2.5% salt) with good flavor, texture and freshness. The contents of alcohol insoluble solid(AIS) and protopectin(PP) of control were more decrensed during fermentation than those of SMB added Kimchi. But, the contents of pectic adid(PA) and water soluble pectin(WSP) of control were more increased during fermentation than those of SMB added Kimchi. Hexose and pentose from hemicellulose in control, PP and PA respectively, were more decreased during fermentation than those in SMB added Kimchi. Lower polarity and higher molecular weight PP was eluted and higher polarity and lower molecular weight PP was decreased considerably in control compared to those in SMB added Kimchi during fermentation.

  • Biofiltration was successfully applied to treat a mixture of volatile organic compounds(benzene, xylene) from contaminated air stream. Immobilized Ps. oleovorans biofilter was evaluated for its value in simultaneous removal of benzene and xylene from waste air stream. The variety of operating conditions were tested to evaluate important factors such as space velocity, pH, water content, etc.

  • Traumatic chylothorax is the presence of lymphatic fluid in the pleural space resulting from thoracic duct rupture, This condition is a serious and often life-threatening clinical entity. Operative trauma is most common mechanism of injury, but we experienced two case of chylothorax due to blunt trauma. One case was treated conservatively, another case was treated surgically.
