This paper presents a result of practical study about the adjustment of load correlation equation for the load management of pole transformer. For adjusting the load correlation equation, we analyze the correlative relation between working electric energy[kWh] and peak load[A]. To enhance the accuracy of correlation equation, we classify the 12 representative area patterns. And then, we select the 24 sample pole transformer for each area pattern. For the reliability of the data using the load correlation equation, load management equipment is utilized for each sample pole transformer. Through the on-line data acquisition, we construct the database. For adjusting the load correlation equation, we consider the two points. One is the goodness of fitness for load correlation equation and the other is prevention of pole transformer damage due to the overload. Finally, we propose the correlation equation using the linear and quadratic equation all at once. Through the case studies, we verify that the proposed load correlation equation is reduced the error ratio than conventional correlation equation.

For the purpose of new‘organizational knowledge centric knowledge management’, this paper proposes the knowledge creating organizational memory which shows the knowledge creation in organization according to the dialectical circulation between the domain knowledge and the task knowledge, based on the Yin Yang theory. This paper defines two kinds of organizational knowledge such as the domain knowledge and task knowledge and designs them in the pursuit of its lifecycle. Knowledge creating organizational memory is designed to three knowledge components that circulate through the domain knowledge and the task knowledge according to the object-oriented methodology. Organizational knowledge is designed into the graphical structure of ( i ) knowledge ( ⅱ ) relation between knowledge objects and ( ⅲ ) degree of relation, which receive the legacy of organizational knowledge such as data schema, process model and knowledge base. This design of organizational knowledge can be applied to CBR(Case Based Reasoning), one of knowledge mining tools to create new organizational knowledge.

Traditional bidding process and activities in public construction area has many problems in terms of the clearness and fairness of administration. And, it causes many cost consumption to suppliers. As part of the efforts to solve these problems, some public institutions developed the electronic bidding systems. But these systems have still problems in diverse aspects. Therefore, the purpose of this study is to analyze current bidding systems through literature survey, case study and process mapping methodology, to compare the result of the analysis with the developed electronic bidding systems and to suggest the improvement for the coming bidding systems. As results of this study, key processes and classified contract types about public construction bidding were identified. These can be applied by means of guidelines when public institutions are planning new electronic bidding systems. The composition of unified driving organization, the database development for information share and the standardization of national level for the new electronic bidding systems were also suggested.

Urban transit is a complex system that is combined electrically and mechanically, it is necessary to construct maintenance system for securing safety accompanying high-speed driving and maintaining promptly. Expert system is a computer program which uses numerical or non-numerical domain-specific knowledge to solve problems. In this research, we intend to develop the expert system which diagnose failure causes quickly and display measures. For the development of expert system, standardization of failure code classification system and creation of BOM(Bill Of Materials) have been first performed. Through the analysis of failure history and maintenance manuals, knowledge base has been constructed. Also, for retrieving the procedure of failure diagnosis and repair linking with the knowledge base, we have built RBR(Rule Based Reasoning) engine by pattern matching technique and CBR(Case Based Reasoning) engine by similarity search method. This system has been developed based on web to maximize the accessibility.

Product opportunity analysis in product planning is to analyze the feasibility for success over the detail product concept, and to grasp the new possible market based on exploring the trends of market and product itself. Therefore, the correct analysis and insight with various data of product and market is needed for product opportunity analysis. As product environment changes rapidly, it is especially important to collect more plentiful informations, and to put these information to practical use pertinently. It is consequently indispensible to clarify the types of information to be needed and to construct product database. However, there has no meaning to gather simple information which is lying here and there. Product database has to be systematically organized and each product information is to be transformed into contextual one. This study clarifies a conceptual framework of product design database based on product attributes and develops prototype of product database for product planning. Case study of camera is exemplified for analyzing the product trends and exploring product opportunity with developed product database.
