This paper reviewed the relationship between information technology system and knowledge management activities, and the moderating effect of industrial type. The results of multiple regression analysis, based on the responses from 219 employees in manufacturing and financing service sector, showed that information technology infrastructure and information technology usage have positive effects on knowledge acquisition, knowledge transfer, and knowledge usage. In moderating effects, information technology infrastructure more positively related with knowledge acquisition in financing service sector than in manufacturing sector. And also information technology usage more positively related with knowledge transfer in financing service sector than in manufacturing sector.

In order to cope with some drawbacks of conventional CCS (Carbon Capture and Storage) technologies, the new way to deal carbon dioxide have been studied a lot. One way to deal emitted carbon dioxide is to convert carbon dioxide into metal carbonate salt which can be used for various purposes such as raw materials for construction, additives for paper-making industries and so on. In this method, securing the source for metal cation is important and in this research, concentrated industrial wastewater was used to supply metal cation. In the wastewater, calcium and magnesium ions were dissolved and this could make cpatured carbon dioxide to be converted to metal carbonate salts. As a result of the chemical conversion, the amount of carbon dioxide converted to the precipitated salts and the crystal structures of them were suggested. To verify the crystal structures and the composition of salt mixtures, Scanning Electron Microscope and X-Ray Diffraction analysis were utilized.
