New education methodologies exploiting new media technologies are emerging with the development of digital technology. There also have been researches on efficient methods to apply new technologies on special education. In this paper, we analyze 32 researches associated with application of new media technology on special education for research theme, media, and teaching types. The analysis results show that there is few research on intervention contents which consider special education environment and the roll of teacher. This motivates us to develop a social storytelling contents to improve sociality of the children with developmental disability which can be easily useable in special education environment. The basic structure of the contents is designed for a child to make a choice in the meantime of storytelling and experience the different results depending on the choice. The pilot test with a child with mild autism verifies that it draws attention from the child and it is easy to use in a special education environment, which lays down the possibility as an intervention content.

The recent trend toward higher frequencies, miniaturization and lower-cost in wireless communication equipment is demanding high density packaging technologies such flip chip interconnection and multichip module(MCM) as a substitute of conventional plastic package. With analyzing the recently reported research results of the RF flip chip, this paper presents the technical issues and advantages of RF flip chip and suggest the flip chip technologies suitable for the development stage. At first, most of RF flip chips are designed in a coplanar waveguide line instead of microstrip in order to achieve better electrical performance and to avoid the interaction with a substrate. Secondly, eliminating wafer back-side grinding, via formation, and back-side metallization enables the manufacturing cost to be reduced. Finally, the electrical performance of flip chip bonding is much better than that of plastic package and the flip chip interconnection is more suitable for Transmit/Receiver modules at higher frequency. However, the characterization of CPW designed RF flip chip must be thoroughly studied and the Au stud bump bonding shall be suggested at the earlier stage of RF flip chip development.
