Main purpose of this study is to investigate the effect of the self-leadership of local public officials on the customer-oriented public service provision. Structural Equation Model was applied to analyze the relationship between self leadership and customer oriented public service attitude. Positive structural relationships between self-leadership and customer-oriented attitude was confirmed from empirical analysis. While variable job-satisfaction took intermediating role between self-leadership and customer-oriented attitude. The result implies that behavioral approach might be a more effective policy measure to improve citizen's satisfaction for public services. For a extended periods, Korean government introduced various institutional arrangements to improve the customer satisfaction for public service. However, the result was not satisfactory. The result of this study suggest behavioral approach to improve public service customer satisfaction.

The safety of gas utilities is intimidated by many causes. Among them, subsidence is a dominant cause to decrease the safety of gas utilities. So it is very important to monitor the displacement of subsidence. The purpose of this study is to on-line monitor the subsidence of gas utilities using Static GPS(Global Positioning System)technique. Static GPS technique, which is one of various GPS techniques and originally applied to monitor the crustal activity, was applied for two gas station in Korea Gas Corporation. Prior to applying this technique to the field, i.e, gas station, a preliminary test was peformed to confirm the accuracy of this technique. As a result, it was proved that this technique can measure the displacement of gas utilities three dimensionally by sub-millimeter. After getting confirmation of GPS technique, we applied this technique for two gas stations and monitored the amount of subsidence during 5 months. As a result of field test, we can conclude that the gas stations was subsiding several millimeters in a year.

The relational data model can't be applied to CAD/CAM, CE, and CIM since it can't support the semantic model concept such as complex object, random data definition, manipulation, version control, generalization, aggregation and so on. In this paper, the IPCS(Integrated Production Control System) for hand-rail of ship is parted into several module according to process function. further more, the object oriented data model is designed with UML(Unified Modeling Language). UML is the object oriented design methodology of industrial standard that combines the Booch's methodology, the Rumbaugh's On(Object Modeling Technique), and the Jacobson's OOSE(Object-Oriented Software Engineering) methodology. The efficient management is expected with object-oriented data model construction, since this developed system can achieve efficient process control, system maintenance, repair and extension.
