Previous studies have focused on individual and organizational learning. Amid an increasingly complex business environment, a team system designed to improve flexibility and adaptability constitutes the most basic part of an organization. Still, team learning has rarely been discussed. In addition, team learning behavior, despite being an important part of a team process, is often mentioned as a team-level outcome variable. Given that team learning behavior involves constant changes in thinking and behavior, a shared belief among team members is needed in order to positively influence innovative performance of a team. In spite of that, there has been only limited discussion of it. Besides, few domestic studies have dealt with R&D teams that can clearly demonstrate team learning behavior and team innovative performance. This study is an empirical analysis of the impact of team efficacy on team innovative performance and the mediating role of team learning behavior based on materials collected from team leaders and their immediate subordinates in 268 R&D teams. The analysis showed that team learning behavior actually has a positive effect on team innovative performance. Team efficacy also turned out to have a positive influence on team learning behavior. Lastly, the study found that team learning behavior played a mediating role in the relationship between team efficacy and team innovative performance. Based on those results, the study has identified implications and suggested directions for future research.

Attention has been focused recently on the concept of shared cognition which encompasses the notion that effective team members hold knowledge that is overlapping and complementary with teammates. This shared cognition is expected to improve team effectiveness. In contrast to the continued efforts in developing theoretical approach of shared cognition, empirical studies are meager. Thus, we conducted an empirical study to investigate the role of shared cognition on team effectiveness. This study classifies shared cognition into two types, team mental model and transactive memory system, by shared meaning. A total of 121 new product development teams in the IT industry were surveyed for the data collection. The results of analysis can be summarized as follows: first, team mental model has a positive influence on team performance, team innovative behavior and team learning effect. And the relation with team mental model and team performance is moderated by the similarity of knowledge structure among the expert. Second, transactive memory system has a positive influence on team performance, team innovative behavior and team learning effect.

High resolution 2.1” QVGA LTPS LCD (190ppi) having high aperture ratio of 65% could be successfully developed using state-of-the-art SLS technology and active/gate storage structure. Cost effective P-MOS 6-Mask structure was used. Full gate and transmission gate circuits are integrated in the panel. The high aperture ratio was obtained by using active/gate capacitance structure, which can reduce storage capacitance area. The aperture ratio was increased to 65% from 49% of conventional gate/data capacitance structure. The brightness was increased from 180cd to 270cd without any degradation of optical properties such as contrast ratio, flicker or crosstalk.

The present study examines the effects of transformational leadership exercised by team leader and transformational leadership shared by team members on team creativity and team performance at the team level. A growing body on leadership research highlights the role of team leadership in work organizations. In team settings, studies have focused exclusively on individual leaders who occupy formal leadership positions and exercise vertical influence over team members. In contrast to this traditional approach, shared leadership highlights a horizontal influence process where leadership is collectively carried out by team members. In this shared form of leadership, members actively participate in the leadership process and horizontally influence other team members. This mutual influence among team members constitutes a critical condition for the success of team-based organizations. The ability of team members to work together as a team is the key to the overall functioning of the team organization. To verify the effect of two leadership styles, we analyze the effect of a leader's transformational leadership and members' shared transformational leadership on team creativity and team performance for the same team. This study also predicts that the transformational leadership shared by members will moderate the effects of leader transformational leadership on team performance and creativity. Our findings show that both leaderships have a positive effect on team performance. However, the main effect of a leader's transformational leadership on team creativity is not significant when members' transformational leadership is employed into the model. With the effect of leader transformational leadership controlled for, the main effects of the transformational leadership shared by members on team creativity and performance are significant. In addition, we also found the significant moderation effects of member transformational leadership by leader transformational leadership on team creativity. Based on these findings, we strongly recommend that team based organizations shift the leadership focus from the leader focused leadership model to the shared leadership model. We also discuss managerial implications of our findings in details.

Highly stable bottom gate thin film transistors(TFTs) with a zinc indium tin oxide(Zn-In-Sn-O:ZITO) channel layer have been fabricated by rf-magnetron co-sputtering using a indium tin oxide(ITO:90/10), a tin oxide and a zinc oxide targets. The ZITO TFT (W/L=$40{\mu}m/20{\mu}m$) has a mobility of 24.6 $cm^2$/V.s, a subthreshold swing of 0.12V/dec., a turn-on voltage of -0.4V and an on/off ratio of >$10^9$. When gate field of $1.8{\times}10^5$ V/cm was applied with source-drain current of $3{\mu}A$ at $60^{\circ}C$, the threshold voltage shift was ~0.18 V after 135 hours. We fabricated AM-OLED driven by highly stable bottom gate Zn-In-Sn-O TFT array.
