  • Those making decisions are no longer located in the same workplace. Wireless technology appears promising as a method to promote group performance in circumstances dependent on time, but not member proximity. However, the success of wireless technology in group decision-making situations has not yet been proven. This paper seeks to learn whether wireless technology affects the performance of group decision-making tasks that should be resolved urgently and/or sources of idea are disconnected with on-line network.

  • We find some array mura are caused by S/D bridge or channel open in 4 mask process. The gray tone PR thickness non-uniformity is the main reason of these defects. By the adjustment of exposure and dry etch parameters, S/D bridge and channel open ratio drops by 10.87%.

  • This paper constructs Croup Technology process-based learning curve model adjusted to a Group Technology environment which accounts for shared learning that occurs when multiple products utilize some of the same process steps. Through this constructed model, the estimated times and productivity of labor calculated by the Group Technology process-based learning curve model are compared with those generated by employing product-based 1 earning curve model. For sensitivity analysis of the model, the impact of learning rate and the ordered production quantity on the ratio differences between Group Technology process-based learning curve model and product-based learning curve model are examined. These results indicate the critical importance of employing Group Technology process-based learning curve model when a process spans multiple products.

  • Ninety KNP were divided into three group by differential market weight(20 of each group): Live weight of Group 1(G 1), Group 2(G 2) and Group 3(G 3) were 50-59kg, 60-69kg, 70-80kg, respectively. Values of pH and shear force showed an increase, while cooking loss showed decreased with increased weight. In color analysis, $a^{\ast}$ value in meat and $b^{\ast}$ value in backfat of KNP showed higher as slaughter weight increased. Slaughter weight did not significantly affect the fatty acid composition of subcutaneous fat of KNP. With the exception of oleic acid in intermuscular fat, there were no significant weight-dependent differences in the fatty acid profiles.

  • Bifacial photovoltaic (PV) technology has received considerable attention in recent years due to the potential to achieve a higher annual energy yield compared to its monofacial PV systems. In this study, we fabricated the bifacial c-Si PV module with a shingled design using the conventional patterned bifacial solar cells. The shingled design PV module has recently attracted attention as a high-power module. Compared to the conventional module, it can have a much more active area due to the busbar-free structure. We employed the transparent backsheet for a light reception at the rear side of the PV module. Finally, we achieved a conversion power of 453.9 W for a 1300 mm × 2000 mm area. Moreover, we perform reliability tests to verify the durability of our Shingled Design Bifacial c-Si Photovoltaic module.
