Yun, Sung Kyu & Jung, Woo-hyun. 2004. Request and Question Perspective in Interlanguage Pragmatics. The Sociolinguistic Journal of Korea, 12(2). This paper is an interlanguage pragmatic study of request and question perspective. It aims to explore whether there are any differences in request perspective between American English native speakers and Korean EFL learners. To this end, this study employed a Discourse Completion Test, which consisted of eight situations. Data were collected from three different groups: native speakers of English; Korean learners of English; native speakers of Korean. The results showed that the learners deviated from native pragmatic norms in the choice of perspective in a relatively systematic way. The same held even more obviously in the use of please in interacting with request perspective. It was also shown that the mismatch between the native and nonnative groups in perspective was an instance of pragmatic transfer. The results suggested that the notions of imposition and politeness operated differently in perspective between the native and nonnative groups. It is expected that this study will shed light on the phenomenon of interlanguage pragmatics and the aspect of pragmatic transfer, revealing how learners differ from native speakers with respect to request perspective and what causes the differences.

<P>An all‐solution‐processed flexible piezoelectric nanogenerator, composed of polycrystalline ZnO thin film and functional polymer layers such as P3HT/PCBM and PEDOT:PSS, generates energy through a mechanical rolling and muscle stretching system. On page 6022, Youn Sang Kim, Sang‐Woo Kim, and co‐workers show that this all‐solution‐processed nanogenerator is feasible as a piezoelectric patchable device and is promising for use in future energy harvesters such as wearable human patches and mobile electronics. </P>

We have successfully decorated reduced graphene oxide (RGO) with silver nanoparticles (AgNPs) by microwaving silver alkylcarbamate for 13 seconds using 1-amino-4-methylpiperazine. Uniform AgNPs (20-40 nm) were effectively prepared, and 1-amino-4-methylpiperazine acted as a reaction medium, reducing agent, and stabilizer. Particle size and morphology were correlated with the silver alkylcarbamate concentration and microwave time. The graphene/AgNPs composites were characterized by Raman, X-ray diffraction, and scanning electron microscopy to confirm that the AgNPs were uniformly decorated onto the graphene. Measurements of the transparent conductive property at room temperature indicated that these graphene/AgNPs nanosheets with 55.45% transmittance were electrically continuous with a sheet resistance of approximately $43{\Omega}/{\Box}$.
