  • Responsiveness and initiative between infant and mother from toy centered play situation at 6, 7 months of age and infant's social communication skills at 12 months were studied in a sample of 62 infant-mother pairs. Through the video analysis, infants were grouped into simple react group, cooperated group, and active initiative group. In the between groups, we analyzed whether mother's initiative act styles and response styles were different, and whether their social communication skills were different when they tested at 12 months. The results showed that mother's initiative styles were not different but mother's response styles were significantly different with infant groups. Further result showed that cooperated group gained higher score than active initiative group in the total score of Eary Social Communication Skills scales at 12 months of age. The results suggested that mother's responsive behaviors were more important than initiative behaviors for the infant's positive interaction, and the difference of these behaviors would lead to a gap of early social communication abilities.

  • Satrec Initiative successfully developed a high-resolution electro-optical camera system, EOS-D Ver.1.0. EOS-D Ver.1.0 is the main payload of DubaiSat-2 and Deimos-2, which are developed based on the SI-300 platform of Satrec Initiative. After the launch and early operation (LEOP) of DubaiSat-2 and Deimos-2, we performed refocusing for the telescope of EOS-D Ver.1.0 to compensate for the dimensional change of its metering structure by moisture out-gassing. Before and after refocusing, we conducted the performance evaluation of thermal control system(TCS) for EOS-D Ver.1.0 using the in-orbit telemetry data. The evaluation showed EOS-D Ver.1.0 was under well-controlled thermal environment, which demonstrates TCS was designed and developed to meet all requirements.
