In this study, catalytic decomposition of chlorobenzene, a model compound of dioxin, was investigated. Catalysts made of a mesoporous material SBA-15 were used. The effect of Pt impregnation on the catalytic activity was evaluated. The catalysts were characterized using BET and NH₃-TPD. The catalytic activity for chlorobenzene removal reaction was shown to increase with the acid amount of catalysts. Addition of Pt to Al-SBA-15 was also shown to enhance the catalytic activity.

In this study, toluene catalytic oxidation was investigated using various metal components (Cu, Ce, Ni, La and Zr) supported on Used FCC zeolite for the application of the waste recycling and odor reduction. Among the metals, 5 wt% Cu/zeolite showed the best catalytic activity. 100 % conversion was achieved at 300℃ which was 50℃ lower than that of other metal components. As increasing the amount of doped Cu, the CuO was formed and the surface area and pore size were decreased. By the reduction treatment before toluene oxidation, the catalytic activity of the oxidation below 250℃ was improved. No decrease of conversion was observed during the continuos reaction at 300℃ for 48 h.

Objective : After arranged and estimated the result of Oriental Medical Health Examination Program, considered the way of improvement and how Oriental Medicine participate in industrial health service. Results : As a point at issue of occidental medicine examination, followings have been indicated, 1) Occidental medical examination is performed by mainly test and instrument and therefore, role of doctors could be excluded and it could be diagnosed only for target disease and 2) in Korea, it could not be conducted in public medical system and therefore improvement effect of public health promotion could not be made due to increase of total medical expenses and infirmity of post management. These points are substantial limit of paradigm resided in occidental medicine and also problem caused by unique characteristics of medical system of Korea. Conclusion : According to the estimate of present special health examination for workers, it seems that special health examination forworkers is a way of specializing the purpose of special health examination and searching the group that needs a special mediation for promoting the health and preventing the disease as a part of industrial health service that needs a connection with other industrial health service. A program replaced by the health effect-oriented methods that limits the purpose of special health examination be studied. After understood the potential health disorder of workers according to where they are exposed to, it also should be contained items for the disease which can be examined in health examination.

Mg-Cu composites were successively fabricated using a combination of rapid solidification and extrusion processes. In addition, the microstructural variation of the composite was investigated by performing the extrusion repeatedly. It resulted that the composite formed an uniform and dense structure by the extrusion, and the microstructure became fine as the extrusion conducted repeatedly. The microstructural variation was known to be dependent on the number of extrusion and the area reduction ratio. The tensile strength was also measured as a function of the microstructural variation.

Fe powders with elongated and aggregated structure as heat pellet material for thermal battery applications were prepared by spray pyrolysis under various preparation conditions. The precursor powders with spherical shapes and hollow morphologies turned into Fe powders after reduction at a temperature of 615˚C under 20% H2/Ar gas. The powders had pure Fe crystal structures irrespective of the preparation conditions of the precursor powders in the spray pyrolysis. The morphologies and mean sizes of the Fe powders are affected by the preparation conditions of the precursor powders in the spray pyrolysis. Therefore, the ignition sensitivities and the burn rates of the heat pellets formed from the Fe powders prepared by spray pyrolysis are affected by the preparations of the precursor powders. The Fe powders prepared under the optimum preparation conditions have a BET surface area of 2.9 m2g1. The heat pellets prepared from the Fe powders with elongated and aggregated structure have a good ignition sensitivity of 1.1W and a high burn rate of 18 cms1.
