Recently, environmental conscious machining becomes one of the most important technology in modern manufacturing industry. Especially in metal cutting, cutting fluid often results in many environmental problems. Many technologies have been developed to reduce the problems of the cutting fluid. But most of the technologies need another devices which sometimes require large space and also are very expensive, such as cooling system. In this paper, air compressor is only used to replace the functions of cutting fluid as semi-dry cutting. Cutting forces, cutting moments, and tool wear were measured to obtain cutting characteristics, and were compared with those of dry cutting and non-dry cutting. In the results of the experiments, semi-dry cutting was found to show better cutting performances than dry cutting and non-dry cutting.

The present study investigates the effects of schema on learners’ reading comprehension of literary and history texts. We try to explore whether schema accumulated by learners affects development in their reading skills in terns of culture and content-based text. This investigation is analyzed vis-a-vis data gathered from interviewing five students at Momo middle school in Gochang Jeonbuk province for one month. The results of the study reveal that prior schemata affect the reading comprehension skill positively. Five subjects were utilized in the investigation. The instruments used were six selected reading materials: one Korean folk tale and one counterpart Greek Myths, and one passage on Korean tradition and one counterpart Filipino tradition, and one passage on Korean history and one counterpart South African history.
