In the paper, the workflow model based on task-driven, which is very common in scenario testing, is analyzed. According to test adequacy criteria in scenario testing, the model is designed to correspond test cases in the light of logic block(LB). The final test cases that conform to the test adequacy criteria can be obtained through test case combination and test case reduction. In the last part of the paper, example of actual workflow is to design the efficient test case. Therefore the method is proved to be effective.展开更多

This scheme can effectively overcome the large time delay, inertia of the export steam and the influencee of object in varying operational parameters. Thus excellent control quality is obtaitud. The present paper describes the development and application of neural network based controller to control the temperature of the boiler＇s export steam. Through simulation in various situations, it validates that the control quality of this control system is apparently superior to the conventional PID control system.展开更多

Nevertheless, it is essential that students will be exposed to the treasures of their culture. The author proposes that we introduce the classics through their literary adaptations into children＇s book, comics, and so on. Adaptation as well as translation involves interpretation. Therefore, through the adaptation, we show the students that classic texts are complicated and potent of many meanings. As an introduction to the works of S. Y. Agnon, the author chose his story ＂From a Foe to a Friend＂ （1992）. ＂From a Foe to a Friend＂ by S. Y. Agnon, is considered to be simple, na＇fve story, the plot is linear and accumulative, almost like a folktale or a children＇s story. And indeed, this story was published （2008） as a children＇s book with illustrations, and also as a comic book （2012）. The author will show how we can use these books, along with the folktale of＂The Three Little Pigs＂ （1890）, which the story＇s plot is based on, to prepare students to the challenge of Agnon＇s literary work. The conceptual framework of this paper is based on Polysystem Theory （Even-Zohar, 1990）, Translation Theory （Toury, 1995）, and adaptation as an interpretation （Shenberg, 1997, 1998）.展开更多
