This study presents a look-ahead release planning approach on the basis of AutoMod simulation model for a sixth-generation thin film transistor liquid crystal display color filter (CF) fab in north Taiwan. The studied CF fab has two identical lines with the processes of black matrix (BM), color layer [red, green, and blue (RGB)], indium tin oxide, and photo spacer (PS). These two lines share two supporting processes, multi-domain vertical alignment (MVA) and laboratory (LAB). MVA has the capability and flexibility to provide the functions of RGB and PS, whereas LAB can provide the functions of BM and RGB. The production release planning becomes cornplex because of the equipment flexibility in supporting each other. An AutoMod simulation mode[ is therefore developed and validated using real data from the fab. The AutoMod simulation model is well representative of the real system with less than 10% difference in throughput in all production stations. Using simulation to look ahead, a production controller can predict potential equipment idleness and make adjustment to better utilize equipment capacity. On the basis of simulation with design of experiments, the proposed simulation-based look-ahead release plan is demonstrated to be effective in improving system throughput. [ABSTRACT FROM AUTHOR]

In this study, a multimedia computer-aided tutorial (MCAT) on the topic of debris-flow hazards was developed for senior high-school students in Taiwan. The format of the new course is a blend of whole-class presentations, interactive discussions among the teacher and students, and classroom activities using the MCAT software. The whole-class presentation was presented using both a laptop computer and a high-resolution liquid crystal display projector to display the MCAT contents on a large white screen in front of a whole class. Besides, class discussions between the teacher and the students and among students were also embedded in the teaching format. Students' earth science learning outcomes were evaluated by administering an achievement test and a survey of attitudes towards the earth science subject before and after the course. The results indicated that MCAT accompanied by the current ‘interactive whole-class teaching’ form could significantly help the students' grasp of earth science concepts and greatly improve their attitudes towards earth science.
