This study investigated differences in the topic performance of 3-year-old Korean and American children. Sixteen mother and child dyads (8 Americans and 8 Koreans) were tape-recorded during naturally occurring conversations. The cape-recorded data were transcribed on the observational chechlist by Kertoy Vetter(1995). Korean children engaged in topic performance nearly twice as often as American children. Korean children engaged in topic termination/initiation and continuation more often than American children. Also, Korean children engaged in topic collaboration and incorporation more often than American children, but there was no difference in off-topic.

Solution-processed n-type organic field effect transistors (OFETs) are in need of proper metal contact for improving injection and mobility, as well as balanced hole mobility for building logic circuit units. We address the two distinct problems by a simple technique of transfer-printing. Transfer-printed Au contacts on a terrylene-based semiconductor (TDI) significantly reduced the inverse subthreshold slope by 5.6V/dec and enhanced the linear mobility by over 5 times compared to evaporated Au contacts. Hence, devices with a high-work-function metal (Au) are comparable with those with low-work-function metals (Al and Ca), indicating a fundamental advantage of transfer-printed electrodes in electron injection. We also transfer-printed a poly(3-hexylthiophene) (P3HT) layer onto TDI to construct a double-channel ambipolar transistor by a solution process for the first time. The transistor exhibits balanced hole and electron mobility (3.0x10<SUP>-3</SUP> and 2.8x10<SUP>-3</SUP>cm<SUP>2</SUP>V<SUP>-1</SUP>s<SUP>-1</SUP>) even in a coplanar structure with symmetric Au electrodes. The technique is especially useful for reaching intrinsic mobility of new materials, and enables significant enlargement of the material tanks for solution-processed functional heterojunction OFETs.

<P>Medical cyber-physical systems (MCPS) are life-critical, context-aware, networked systems of medical devices. These systems are increasingly used in hospitals to provide high-quality continuous care for patients. The need to design complex MCPS that are both safe and effective has presented numerous challenges, including achieving high assurance in system software, intoperability, context-aware intelligence, autonomy, security and privacy, and device certifiability. In this paper, we discuss these challenges in developing MCPS, some of our work in addressing them, and several open research issues.</P>
