Metal films (i.e., Ti, Al and SUH310S) were prepared in a magnetron sputtering apparatus, and their cross-sectional structures were investigated using scanning electron microscopy. The apparatus used consisted of a cylindrical metal target which was electrically grounded, and two anode rings attached to the top and to the bottom of the target. A wire was placed along the center-line of the cylindrical target to provide a substrate. When the electrical potential of the substrate was varied, the metal-film formation rate depended on both the discharge voltage and the electrical potential of the substrate. As we made the magnetic field stronger, the plasma which appeared near the target collected on the plasma wall surface and thereby decreased the bias current. The bias current on the conducting wire was different from that for cation collection. The bias current decreased because the collection of cations decreased when we increased the magnetic-coil current. When the substrate was electrically isolated, the films deposited showed a slightly coarse columnar structure with thin voids between adjacent columns. In contrast, in the case of the grounded substrate, the deposited film did not show any clear columns but instead, showed a densely-packed granular structure. No peeling region was observed between the film and substrate, indicating good adhesion.

The combustion kinetics of the imported bituminous coal was studied in the interme-diated heating rate. The activation energy and the frequency factor were obtained by experi-ment of the coal weight loss depending on the combustion time with Ih. furnace. The experi-ments were performed in the heating rates of $1,5,10^{\circ}C/sec\;or\;20^{\circ}C/sec\;at\;the\;600-900^{\circ}C$ maximum temperature, The values of the activation energy(E) which were calculated from the experimental data existed in the range from 3000cal/g-mol to 15000cal/g-mol, and those of the frequency $factor(1nk_O)$ were in the range from 4.5cm/sec to 11.5cm/sec.

During the period of decentralization and innovation, RIS(Regional Innovation System) is needed for a region to build its own Innovation System in order to gain competitive power. It would be possible for a region to continue to seek sustainable growth only if it can come up with new information constantly by helping to create and spread its own project planning ability and drive ability innovation. Above all, as an innovator, coordinator, facilitator and linker, RIC(Reginal Innovation Council) in Kyeong-ju should build up its internal capacity. In order to improve efficiency of running the Innovation Council we should also hurry to construct the infrastructure, such as build up of office work. and By activating the support system of Section Council, we should lay the groundwork for the task - the spread of innovation atmosphere in the region and the buildup of the capacity in the regional innovation council. We should make constant efforts to make Keyong-ju unique by learning and educating incessant innovation as well as strengthening promotions.
