The purpose of this study was to look into whether this mathematising learning utilizing realistic context has an effect on the mathematical thinking. To solve the above problem, two 5th grade classes of D Elementary School in Seoul were selected for performing necessary experiments with one class designated as an experimental group and the other class as a comparative group. Throughout 17 times for six weeks, the comparative group was educated with general mathematics learning by mathematics and "mathematics practices," while the experimental group was taught mainly with mathematising learning using realistic context. As a result, to start with, in case of the experimental group that conducted the mathematising learning utilizing realistic coherence, in the analogical and developmental thoughts which are mathematical thoughts related to the methods of mathematics, in the thinking of expression and the one of basic character which are mathematical thoughts related to the contents of mathematics, and in the thinking of operation, the average points were improved more than the comparative group, also having statistically significant differences. The study suggested that it is necessary to conduct subsequent studies that can verify by expanding to each grade, sex and region, develop teaching methods suitably to the other content domains and purposes of figures, and demonstrate the effects. In addition to those, evaluation tools which can evaluate the mathematical thinking processes of children appropriately and in more diversified methods will have to be developed. Furthermore, in order to maximize mathematising for each group in each mathematising process, it would be necessary to make efforts for further developing realistic problem situations, works and work sheets, which are adequate to the characteristics of the upper and lower groups.

The goal of mathematics education in the 7-th national curriculum is focused on maximizing learning effectiveness through teaching mathematics, considering learning contents and levels appropriate to various levels of students' abilities. Thus, reduction of contents, learner-centered way of teaching, and multi-step differentiated learning are centered around the curriculum. However, in reality one of the most difficult problems mentioned by many inservice teachers is that students are not interested in school mathematics because some of them tended to learn mathematics in advance in private institutes and others felt difficult from school mathematics. Thus, alternative solutions are strongly required. When students are more interested in mathematics classes and instructional materials, as a more effective way of teaching, are appropriately used, problems mentioned above are expected to be solved. In order to solve problems, additionally, this study investigated the amount of time assigned to each area of mathematics textbooks from level 1-A to level 6-B, which are currently used in elementary school. This study also examined inservice teachers' views about how instructional materials should be used. This will be helpful on using and developing instructional materials, and it will lead to more exciting classes of mathematics. However, these teaching materials need to be carefully used regarding their relationships with pedagogical transfer, metacognitive movement, and localization.

The study aims to figure phenomena and changes that underachievers in mathematics show in the process of learning a function. It is necessary to remind basic concepts once again in advance at a time of teaching underachievers in mathematics to check what they have difficulties in learning for further teaching later on. Five participating students said that teachers' detailed explanation was more helpful, and they found it difficult to learn tables, graphs and formulas at first, but as time progressed, they naturally accepted them. In this regard, it is necessary to use various expressions and means to teach underachievers in mathematics.

In this paper, we propose a hierarchical hybrid neural network for detecting faults of induction motor. Implementing the classifier based on the input and output data, we apply appropriate transform and classification method at each step. In the proposed method, after obtaining the current of state of motor for each period, we transform it by Principle Component Analysis(PCA) to reduce its dimension. Before the training process, we use the conditional Fuzzy C-means(FCM) for obtaining the initial parameters of neural network for more effective learning procedure. From the various simulations, we find that the proposed method shows better performance to detect and diagnosis of induction motor and compare than other methods.

The Information and Communication Technology(ICT) is applied variously by advanced development, however that also causes the ethical problem simultaneously nowadays. It is emphasized the necessity of information and communication ethics and the scheme also is suggested that the student actually may produce and use their own UCC as an educational material which relates to ethics of information and communication in this paper. By doing that activity, student could learn themselves from what they've produced. Therefore they can approach the subject with more interests, beside the method how teacher has been teaching normally which can be described as cramming. The suggestion is phased by the steps as below; First of all, adequate guidance is selected and the aim of education is established to the method of education through producing UCC by analyzing the contents system of information and communication ethics. Second, it is analyzed educational effect along media of UCC. Third, it is analyzed educational effect along the producing format of UCC. Finally, the scheme is developed that student could be learned from UCC they have created. Therefore, students could be participated by themselves more actively to the education and manage the negative effects of ICT. They also could acknowledge and determine the right ethical awareness of information and communication, and develop more advanced ethical awareness by doing this activity.
