Building a Knowledge Brokering System using Social Network Analysis
Youngjoon Jun,Euiho Suh,Sungjin Kim 한국경영정보학회 2010 한국경영정보학회 학술대회논문집 Vol.2010 No.1
The importance of knowledge is increasing in our global and knowledge-based society. As a part of knowledge management, successful knowledge transfer can improve an organization’s competitive advantages and increase an organization’s valuable knowledge assets. However, knowledge transfer is complex and a lot of factors exist that affect successful knowledge transfer such as context, social networks, and IT/IS. This paper focusses on the role of the knowledge broker which is a link between knowledge seekers and knowledge experts. In this context, this research involved implementing a Knowledge Brokering System, called a K-broker system, as a prototype system to improve knowledge transfer in an organization based on an analysis of users’ social network. The K-broker system can provide a ‘single view’ screen for identifying knowledge experts and has no bottlenecks in contrast with a human knowledge broker. Furthermore, it can provide a permanent communication channel between knowledge seekers and knowledge experts.

The feasibility of using benzotriazole (BTAH) to inhibit pitting corrosion in the sprinkler copper tubes was investigated by filling the tubes with BTAH-water solution in 829 households at an eight-year-old apartment complex. The water leakage rate was reduced by approximately 90% following BTAH treatment during 161 days from the previous year. The leakage of one of the two sprinkler copper tubes was investigated with optical microscopy, scanning electron microscopy, energy dispersive spectroscopy, X-ray photoelectron spectroscopy, and X-ray diffraction analysis to determine the formation of Cu-BTA film inside the corrosion pits. All the inner components of the corrosion pits were coated with Cu-BTA films suggesting that BTAH molecules penetrated the corrosion products. The Cu-BTA film was about 2 nm in thickness at the bottom of a corrosion pit. A layer of CuCl and Cu<sub>2</sub>O phases lies under the Cu-BTA film. This complex structure effectively prevented the propagation of corrosion pits in the sprinkler copper tubes and reduced the water leakage.
