  • We introduce our in-house program, NANOCAD, for the modeling and simulation of carrier transport in nanoscale MOSFET devices including quantum-mechanical effects, which implements two kinds of modeling approaches: the top-down approach based on the macroscopic quantum correction model and the bottom-up approach based on the microscopic non-equilibrium Green’s function formalism. We briefly review these two approaches and show their applications to the nanoscale bulk MOSFET device and silicon nanowire transistor, respectively.

  • The purpose of this study was to investigate the effects of science based enrichment STEAM gifted program on the creative thinking activities and emotional intelligence of elementary science gifted students. The study subjects were two science gifted classes of the 5th grade of local Office of Education in B Metropolitan City. One class including 20 students was experimental group and the other including 20 students was comparison group. For the purpose of study, the lesson unit 'The world of light through science' was practised, the science based enrichment STEAM gifted program was applied to experimental group, whereas comparison group was taught traditional gifted lesson. The results of this study were as follows. First, science based enrichment STEAM gifted program influenced significantly the improvement of the creative thinking activities of elementary science gifted students. Second, science based enrichment STEAM gifted program was showed to enhance the emotional intelligence of elementary science gifted students significantly.

  • We introduce a novel method for reconstructing the projected matter distributions of galaxy clusters with weak-lensing (WL) data based on convolutional neural network (CNN). We control the noise level of the galaxy shear catalog such that it mimics the typical properties of the existing Subaru/Suprime-Cam WL observations of galaxy clusters. We find that our mass reconstruction based on multi-layered CNN with architectures of alternating convolution and trans-convolution filters significantly outperforms the traditional mass reconstruction methods.
