To use a language is not just a simple activity of reading or writing letters. Rather it is to grasp the meaning of the letters and to express it in user’s own language. In author’s own experience. most students who have reading difficulties do not use a language in the strict sense. It is not easy to improve their language ability. although teachers try to help them for their language ability and they have an eager desire to improve their language ability. This study has been motivated by a question of how the students with reading difficulty can improve their reading competence Man symbolizes informations visually and linguistically. When we hear a story. it is easy to understand and memorize the meaning of the story if we make concrete visual images in our mind. The graphic organizer instruction can be supposed to help the students who have reading difficulties to relate one of their‘ learning tasks to the other in meaningful way and to develop their cognitive structure. The purpose of this study is to improve the reading competence of students who have reading difficulties by graphic organizers. For this purpose , in chapter 2. I examine theories on the relationship between text structure and graphic organizer , the effect of graphic organizer on reading competence. characteristics of underachievement in reading and proper ways to use graphic organizers in teaching In chapter 3, I devise research method and procedures of this study project. To verify the research hypothesis ‘graphic organizers will improve reading competence of students who have reading difficulty. I design a special program for 34th grade children who have reading difficulties. In chapter 4. I explain about teaching contents in each stage of the program for improving underachievers’reading ability which is devised by the researcher using graphic organizers. I also illustrate a teaching model for each instructional unit according to researcher's idea of graphic organizer instruction. I present a practical example of instruction according to the program and introduce how the teaching method has been changed by this program‘ In chapter 5, I describe and analyse how the underachievers' reading competence has been improved through the program which consists of baseline test. 15 times interventions and maintenance stage. The students' reading competence has been gradually improved from the first stage of graphic organizer instruction. when the graphic organizer was divided into 4 stages and intervened into teaching, and the improvement has been stably kept up during the maintenance period. Therefore. it can be conclude that the graphic organizer instruction is effective to improve the reading competence of students with reading difficulties The significance of this study is that the reading competence of children with reading difficulties has been improved by graphic organizer instruction which helps children not only to acquire the form and the making rule of graphic organizers , but also to reconstruct the content of the text in their own language and thinking. This study provide an opportunity for‘teachers. to predict and to treat children’s responses In teaching and learning situation. based on children' s responses shown in this study report. The result of this study cannot be generalized. because this study has been conducted with only on 34th grade children who have reading difficulty focused only on explanatory texts. Therefore. for further studies. it is recommended to extend numbers of children and types of text and to develop a more effective method for improving reading competence by a more proper research design. It is also recommended to research into characteristics of students with reading difficulties based on children's responses which has been shown throughout the whole stages of graphic organizer instruction.

Grinding System is very difficult to examine closely wear phenomenon or dynamic characterastic, because it is very complex and different from a general cutting system. Considering automatization and precision, it is very important to examine closely grinding system. In this study, grinding wheel surface is acquired by using computer vision system in order to explain wear and loading phenomenon. We investigate the relationship between wear and Fourier spectrum of acquired image, and observe the entropy variation in the process of manufacturing.

Mordern industrial society pursues unmanned system and automation of manufacturing process. Abreast with this tendensy, production of goods which requires advanced accuracy is increasing as well. According to this, the work sensing time of dressing by monitoring and diagnosing the condition of grinding, which is th representative way in accurate manufacturing, is an important work to prevent serious damages which affect grinding process or products by wearing grinding wheel. Computer vision system was composed, so that grinding wheel surface was acquired by CCD camera and the change of cutting edge ratio was measured. Then we used automatic thresholding technique from histogram as a way of dividing grinding cutting edge from grinding surface. As a result, we are trying to approach unmanned system and automation by deciding more accurate time of dressing and by visualizing behavior of grinding wheel by making use of computer vision.
