4 Research and Development We will continue to expand in the future R&D manpower experimental equipments and resources of investment in an effort to enhance the R&D capabilities. Furthermore, we will dispatch our R&D manpower abroad to study the special technology as well as to ally with overseas partners who has the required technology to enhance our technological capacities through which we will achieve the commercialization of new products by all means. The technological goal is to develop the most up-to-date materials on the basis of accumulated know-how and technology like membrane sheet, through which we will accomplish the substitution our high efficiency filters for imported foreign products necessarily required for up-to-date semiconductor and bio technology industries. In order to meet our commitment above, we will devote ourselves to play the pivotal role of beacon for semiconductor and biology industries.
