House dust mite was the most important cause of allergic asthma and rhinitis. More than 70% of Korean childrenand about 50% of adult with respiratory allergy were sensitive to house dust mite.This experiment was indoor environment in house and house dust mite existence inquiry. From 23rd December2005 to 28th February 2006, dust samples were collected from the bedclothes by a vacuum cleaner and air sampler.And the levels of Der f1 and Der p1 were determined by ELISA((Enzyme-Linked Immunosorbent Assay).The results were as follows :ng/g).2. In type of dust mite, the Korean house the almost have the D. farinaeother than D. pteronyeeinusof mite.3. The Der f1 and Der p1 levels per gram of dust from the bedclothes were 2074.99ng on average, but they didnot exist in air.The concentrations of house dust mite were significantly high in the bedclothes. This results suggest that theenvironment should be emphasized to prevent the sensitization by the repeated exposure to dust mite.

This study is to discuss the factors influenced on the removal efficiency of a high-strength organic wastewaters investigated using the polypropyrene media which appropriate to attach microorganism in the tube type fixed biofilter reactor. The results obtained in the experiment were as follows: 1. The kinetics of reaction rate (k') were 0.125, 0.135, 0.155 varing initial COD 720, 1280, 1630 mg/l in batch reactor. 2. In the range of pH 4.0 ~12.0 was obtained the removal efficiency of COD higher than 85%. It was proved that variation of pH (4.0 ~12.0) was nothing to do with the removal efficiency of substrate in continuous reactor. 3. Temperature to obtain removal efficiency of COD higher than 85% was 10 ~ 40$\circ$C. Removal efficiency of COD was no less than those at high temperature. 4. In the continuous reactor, the volumetric loading of COD for removal efficiency higher than 95% had to be 0.5~1.5 kg COD/m$^3$.d below. And then the HRT was 8 hrs. 5. In comparison with the activated sludge process, the tube type fixed biofilter process was excellent in removal efficiency of substrate and sludge production rate.

The study was performed to investigate the influence of dust transportation from China contient to Korea by Yellow Sand phenomena and evaluate the aerosol during the period of Yellow Sand phenomena in Seoul, from Apr. to Oct. 1998. The TSP(Total Suspended Particulates) was collected by High Volume Air Sampler. The concentration of heavy metals in TSP were analysed by AAS and the inorganic ion of TSP were analysed by IC. The results were as follows: 1. The average concentration of TSP were 249.18㎍/㎥ at sampling point during the Yellow Sand phenomena were twice higher than that in Non-Yellow Sand which was 121.98㎍/㎥. 2. The average concentration of heavy metals in TSP during Yellow Sand phenomena and Non-Yellow Sand were Zn>Al>Fe>Pb>Mn>Cr>Ni>Cu>Cd. 3. In comparion with the ordinary time, the average concentration of anionic ions in TSP during Yellow Sand phenomena were Cl^(-)>S0₄^(2)>NO₃^(-)>F^(-)>P0₄>Br^(-), those of Non-Yellow Sand were Cl^(-)>NO₃^(-)>SO₄^(-2)>F^(-)>PO₄^>Br^(-), and that of cationic ions in TSP during Yellow Sand phenomena were Na^(+)>K^(+)>NH₄^(+).
