급변하는 경영환경에서 기업전략의 실행도구로 IT를 활용하고 있으며 이를 통해 기업의 경쟁력을 강화하고 있다. 나아가 단일 기업의 정보화뿐만 아니라 가치사슬에 포함되어 있는 기업들의 정보화를 통하여 산업 전체의 시너지를 낼 수 있다. 하지만 체계적인 정보화 전략 없이 주먹구구식으로 정보시스템을 구축하여 많은 투자에도 불구하고 시스템의 통합성, 호환성 부족, 중복투자, 업무지원의 비효과성 등 많은 문제점이 지적되고 있다. 포스데이타에서는 이러한 기업들의 정보화 현안과 문제점을 해결하기 위한 방안으로 IT진단 컨설팅 방법론을 개발하였다. 기업 정보화 비전, 현안을 분석하여 개선 방향과 체계적인 계획수립을 지원하는 방법론 Framework를 제시하고, IT진단의 영역인 Strategy, Process, Organization, Technology별로 진단목적에 따른 방법에 대해 논하고자 한다. 또한 최근에 그룹사에 IT 진단 방법론을 적용한 컨설팅 사례에서 짧은 기간에 깊이 있는 진단결과와 경영전략과 연계된 정보화 개선방안을 제시함으로써 경영진의 만족도가 높아지고 실행과제가 빠르게 실행되는 효과를 확인하였다.

This paper investigated a gate driver circuit with amorphous silicon for mobile TFT-LCD. In the conventional circuit, the fluctuation of the off-state voltage causes the fluctuation of gate line voltages in the panel and then image quality becomes worse. Newly designed gate driver circuit with dynamic switching inverter and carry out signal reduce the fluctuation of the off-state voltage because dynamic switching inverter is holding the off-state voltage and the delay of carry signal is reduced. The simulation results show that the proposed a-Si:H gate driver has low noise and high stability compared with the conventional one.

Different from the LCD that have two glass substrates on the top and the bottom, EPD have an advantage that is using the bottom glass substrate and the top e-ink sheet. So, it is impossible to apply R or C type TSP that need bottom and top glass plane. We successfully implemented the TSP (Touch Screen Panel) based on the light over the EPD (Electro Phoretic Display).

We developed an a-Si TFT-LCD panel with integrated gate driver circuit using a standard 5-MASK process. To minimize the effect of the a-Si TFT current and LC's capacitance variation with temperature, we developed a new a-Si TFT circuit structure and minimized coupling capacitance by changing vertical architecture above gate driver circuit. Integration of gate driver circuit on glass substrate enables single chip and 3-side free panel structure in a-Si TFT-LCD of QVGA ($240{\times}320$) resolution. And using double ASG structure the dead space of TFT-LCD panel could be further decreased.

Many corporations are accepting various kinds of business reform techniques to be adapted and overcome in this e-Business period. Among these techniques, team-organization is selected most in person/organization field. The introduction of team-organization is more needed and spread, so many corporations actually constructed team-organization formation form. But the result has not been active. Therefore after team-organization is introduced to improve the performance evaluation of team management, the result of team management performance should be correctly measured to find out and settle the problems of team-organization. The purpose of this research presents the development of the model of team-management performance evaluation and the method of the proper measurement based on BSC.

Teams play an indispensable role in helping an organization achieve its goal. Since constant interaction among team members is the cornerstone of team competitiveness, it is necessary for the team members to commit themselves to shared goals-team commitment, a type of positive, emotional attitude of team members. Constant interactions among team members, however, inevitably breed a byproduct called conflict. Though intra-team conflict has both positive and negative effects on team performance, little research has been done to clarify the roles that relationship, task and process conflicts play in team commitment. This research is an empirical investigation of the relationship among the three types of conflicts - relationship, task and process conflicts - based on data collected from 232 R&D teams of 13 Korean companies. The analysis suggests that, while relationship conflict has a negative impact on team commitment, task and process conflicts have no significant impact on team commitment. As for the relationships among those three types of conflict, process conflict has positively influenced task, and relationship conflicts and task conflict also has had a positive impact on relationship conflict. Based on these results, this study has presented its implications and directions for future research.

Liquid crystal molecules with a new fluoro-isothiocyanate moiety were synthesized. They showed remarkably high $T_{NI}$ (>190 $^{\circ}C$), wide mesophase range of 170 $^{\circ}C$, high dielectric anisotropy (>14) and high optical anisotropy (>0.28). New LC Mixtures of the high $T_{NI}$ (>$85^{\circ}C$) was blended with the novel fluoro-isothiocyanate containing LC molecules, phenylcyclohexanes, bicyclohexanes and ester compounds. The LC mixtures show a fast speed (<10ms) of the below one frame rate in 17" WXGA panel.

The process of cold rolling is becoming more severe with the increase in the production of high tensile steel strip as a result of increased demand. Consequently, there is a need to develop work roll materials with better resistance to wear and roll failure. DOOSAN has developed an improved in-house 5%Cr alloy, New HSR1, with properties superior to the existing in- house 5%Cr alloy, Old HSR1. Test alloys were designed with controlled amounts of Si and Mn based on Old HSR1 and an optimum alloy was chosen based on thermal shock tests. A prototype work roll was manufactured with New HSR1, and properties of test specimens were evaluated. The results indicated that New HSR1 has better properties than Old HSR1. After application of New HSR1 work rolls, productivity increased due to advanced resistance to wear and roll failure.
