Histidine phosphorylation (pHis) is increasingly recognized as an important post translational modification (PTM) in regulating cellular functions in eukaryotes. In order to clarify the role of pHis in mammalian cell signaling system, a global phosphorylation study was performed in human prostate cancer cells, PC-3M, using a TiO₂ affinity chromatography. A total number of 307 pHis sites were identified on the 268 proteins among total identified 9,924 phosphorylation sites on 3,316 proteins. In addition, 22 pHis proteins were classified in enzyme category. This report provides the first database for the study of pHis in prostate cancer cells.

This paper aims to apply two ways of student evaluation, i.e. peer- and self-evaluation to TBL(team based learning) class and to explore the difference between two evaluations by gender and grade as well as their relationships, and finally to provide an explanation for the improvement of evaluation ways in TBL class. There has been much research about TBL and its related factors. However, according to the examination of both domestic and overseas researches concerning the application of peer- and self-evaluation to TBL class, few studies have focused on them in terms of the engineering curriculum. This study was conducted with 251 engineering students at P University, and peer- and self-evaluation in TBL class have been measured. Our findings show that firstly, there were significant grade differences in self-evaluation of engineering students. Second, there were no significant gender and grade differences in peer-evaluation. Third, we found a significant correlation between the two factors, self- and peer-evaluation. Also there was a significant correlation among variables of subcategories. Based on these findings, it is expected to provide an explanation for the application of peer- and self-evaluation in TBL class and will be useful for the improvement plans of the related courses in engineering school.

We designed and applied team project based learning for effective computer programming education and analyzed the effect on learning effect. Throughout simplified traditional theories and practices, teamed up with random lottery, divided role & responsibility, and conducted problem solving projects in a competitive way for a given task. When after completion of the course, we conducted questionnaires on learners in order to grasp the influence factors on the learning effect. As a result of the structural equation model analysis, it was shown that Team Project had a direct effect on the learning effect. The learning effect based on the relationships among the factors derived through exploratory factor analysis. Based on this analysis, we propose a more effective computer programming education way.

In this work, we report on a new monitoring method for an organic light-emitting diode (OLED) panel for lighting by optical sensing of the wave-guided light in the substrate. Using microlens array films, the wave-guided light was extracted into the edge or back side of the panel to be monitored by a photodiode. The luminance of the extracted light was measured as linearly proportional to the front light. Thus, by converting the extracted light into photo voltage, monitoring the luminance change occurring in the OLED is possible. Based on the results and concepts, we have proposed a photodiode-equipped driving circuit which can generate compensated driving current for uniform luminance of OLED panels.

Eleven compounds (1-11) were isolated from the rhizomes of Osmunda japonica, and their structures were elucidated based on $^1H$, $^{13}C-NMR$ and LC-IT-TOF MS data. Of these compounds, all compounds (1 - 11) have been previously reported, although five (6 - 9, 11) have not previously been isolated from this plant. The antioxidant activities of isolated compounds (1 - 11) were measured by DPPH and ABTS assays, and compound 10 showed the high antioxidant activity.

IT projects need engineers with various backgrounds to cooperate to build an IT system that satisfy the requirements of users given a limited expense and time. Such diversity of team members and the complexity of task naturally involve considerable amount of conflict among team members. High level of conflict among team members is known to be detrimental to the performance of the team. The purpose of this study is to examine the reasons for conflicts among team members in IT projects and to check how the level of conflict affects the performance of a project and the satisfaction of the members of the project team. To test the relationship, a survey on 166 participants in IT projects was conducted. The reasons for conflicts in IT projects were categorized into five types. The level of ambiguity was found to have a significant correlation with the level of conflict. And the level of conflict, in turn, is found to have a significant effect on the degree of satisfaction among team members and the project results. Based on the research results, it is suggested that a clear definition of tasks and their boundaries is required to reduce ambiguity and thus, the level of conflict and improve the level of satisfaction of IT project team members.

Since the scalability of OLED process is crucial factor for large-sized TV manufacturing, various technologies are reviewed based on the published information. Despite of recent technology advancement enabling high color purity, large-sized AMOLED, a lot of problems to solve still exist to enter the large-sized display market. Here, Samsung will discuss what has to be concerned for large panel and how far the OLED technologies need to go more for the large-sized AMOLED TV marketplace.

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.

In this paper, we presents a new disparity map refinement algorithm using statistical characteristics of disparity map and edge information. The proposed algorithm generate a refined disparity map using disparity maps which are obtained from area and feature-based Stereo Matching by selecting a disparity value of edge point based on the statistics of both disparity maps. Experimental results on aerial stereo image show the better results than conventional fusion algorithms in the disparity error. This algorithm can be applied to the reconstruction of building image from the high resolution remote sensing data.

When the ground subsystem of Ground Based Augmentation System(GBAS) is installed at the airport, the functions and performance of subsystem should be evaluated through ground and flight testing at the pre-commissioning phase. In the case of GBAS flight testing, it can be conducted by the existing flight check aircraft, but the GBAS ground testing requires the development of specially customized equipment to perform the ground testing. Therefore, this paper describes the preliminary design of GBAS onboard test equipment which can be independently used for the GBAS ground testing and flight testing on a car and an aircraft.
