Composite membranes containing a metal complex as an oxygen carrier were prepared and tested for the capability of oxygen enrichment. The permeability characteristics of the membrane were measured by the volumetric method with the pressure difference ranging from 0.2 to 0.8Kg/cm². Both oxygen and nitrogen showed constant permeabilities, diffusion coefficients, and solubilities which do not depend on the pressure difference across the membrane. The metal complexes were also found to play a role of nitrogen carrier to a degree. For the case of the silicone membrane with Co(NO₃)₂.6H₂O complex, the permeability and the separation factor of oxygen were significantly improved to ??/cm³·cm/cm²·sec·cm-Hg and 2.7 respectively, at the pressure difference of 0.4Kg/cm². This improvement was attributed to the metal complex which acts as an oxygen carrier and thus increases the solubility of oxygen in the membrane.

Yongdam multipurpose dam is under construction to divert a part of Geum riverflow to Mankyung watershed and to supply the domestic water to the Chunju region and produce the hydro-electricity. Generally, construction of dam by the method of inter-regional water transfer affects the quantity and quality of water in the down streams and reservoirs. The impact of operation plan of Yongdam dam on the quantity and quality of water in the Geum river and Daechung dam was investigated. It was recommended that the discharge of water transfer from one watershed to another should be minimized as much as possible.

A Multi-measurement system for continuous monitoring of dissolved oxygen, temperature, pH, conductivity was suggested to evaluate the quality of livestock wastewater. The system was tested in the laboratory scale to see its stability for 6 continuous days.'rho resultant data suggested that the system might be applied to the development of water Qualify automatic alarming system in the agricultural area.
