This study examined the structural relationships among parental attitudes and expectations toward mathematics, mathematics motivation and achievement of their child in PISA 2012 of South Korea. Data were analyzed using structural equation modeling(SEM) analysis. The results were as follows: First, parental attitudes toward mathematics had positive effects on parent academic and professional expectations in mathematics. Second, parental expectations also had positive effects on intrinsic motivation, instrumental motivation and math achievement for their child. Third, instrumental motivation had strongest effects on math achievement. The next factors which had effects on math achievement were intrinsic motivation and parental expectations in order. This results shows that the parental awareness of the usefulness and necessity of mathematics will help to increase the interest and value toward mathematics, math achievement and interest of math related carriers of their child.

This paper describes the performance of a full-authority neural network-based fault tolerant system within a flight control system. This fault tolerant flight control system integrates sensor and actuator failure detection, identification, and accommodation (SFDIA and AFDIA), The first task is achieved by incorporating a main neural network (MNN) and a set of n decentralized neural networks (DNNs) to create a system for achieving fault tolerant capabilities for a system with n sensors assumed to be without physical redundancy The second scheme implements the same main neural network integrated with three neural network controllers (NNCs). The function of NNCs is to regain equilibrium and to compensate for the pitching, rolling. and yawing moments induced by the failure. Particular emphasis is placed in this study toward achieving an efficient integration between SFDIA and AFDIA without degradation of performance in terms of false alarm rates and incorrect failure identification. The results of the simulation with different actuator and sensor failures are presented and discussed.

The research area for solving question answering (QA) problems using artificial intelligence models is in a methodological transition period, and one such architecture, the dynamic memory network (DMN), is drawing attention for two key attributes: its attention mechanism defined by neural network operations and its modular architecture imitating cognition processes during QA of human. In this paper, we increased accuracy of the inferred answers, by adapting an automatic data augmentation method for lacking amount of training data, and by improving the ability of time perception. The experimental results showed that in the 1K-bAbI tasks, the modified DMN achieves 89.21% accuracy and passes twelve tasks which is 13.58% higher with passing four more tasks, as compared with one implementation of DMN. Additionally, DMN's word embedding vectors form strong clusters after training. Moreover, the number of episodic passes and that of supporting facts shows direct correlation, which affects the performance significantly.

In this paper, the researchers investigated the influence of graphing calculator in learning the concept of linear function for the gifted students. Elementary students who were taking a course in enrichment mathematics at Science Education Institute for the Gifted in Mokpo National University were selected for this study. The researchers analyzed students' processes of mathematical inference and conjecture, and students' algebraic description. We found the facts that the visualization using a graphing calculator and CBL is helpful to the gifted students in understanding concepts of liner function, finding the relationship between variables, analyzing and presupposing of graph. But, using graphing calculator can be a factor that disturbs learning of students who have too much of curiosity on graphing calculator.

This study attempts to suggest a new direction of the plastic arts education, first by examining a variety of cases in the admission policy depending on the existence of students' preeducation; and second, by analyzing the work process of students who were admitted. The flexible admission policy should be provided to select both groups of students: students with preeducation and students without preeducation. It is requested that the uniform selectional standard adopted by most universities should be changed into the diverse standards that can evaluate different educational back ground of students. This study will be helpful for the university professors to prepare for the new educational foundation and direction by enhancing the efficiency of teaching. This study also aims to suggest the curriculum and methods of the design education to provide the effective teaching of plastic arts and there by develop the better methods of education in this area.

The purpose of this study is to investigate the relation between major subjects of industrial circle high school and mathematics matched with present 2007 revision curriculum. We compare and analyze learning contents in industrial circle's math education via various aspects including methods of explanations, contents domains, and contents levels. The analysis followed by the research study performed with literature study of curriculums and text books. Our research indicates that school curriculum should be reflected relation between industrial high school's each major course and mathematics, so each major course curriculum should be different. Many contents beyond high school mathematics were founded. Hence suitable mathematical maturity and levels within standard high school math curriculum should be considered when one make text books of major course in industrial circle high school.

This paper analysed the mathematical paradoxes which would be based in the probability and statistics. Teachers need to endeavor various data in order to lead student's interest. This paper says mathematical paradoxes in mathematics education makes student have interest and concern when they study mathematics. So, teachers will recognize the need and efficiency of class for using mathematical Paradoxes, students will be promoted to study mathematics by having interest and concern. These study can show the value of paradoxes in the concept of probability and statistics, and illuminate the concept being taught in classroom. Consequently, mathematical paradoxes in mathematics education can be used efficient studying tool.

The purpose of this study is to research the effects of English reading strategies on English reading comprehension by Korean college students. Reading strategy use was assessed through Oxford's self-report questionnaire in reading strategies. This study has three research questions. The first question was to investigate some reading strategies used by college students. The second question was to investigate the differences in reading strategies between two groups in gender. The third question was to investigate the differences in reading strategies of three college student groups according to their English proficiency estimated by reading scores. Some major findings of this study are as follows. First, college English learners use memory strategies most frequently of the six strategies, while using metacognitive strategies least frequently. Second, there exists a significant difference in reading strategies between the gender group. Third, there also exists a significant difference in reading strategies among the three groups divided according to English proficiency. This study shows that students' reading ability can be strengthened and motivated by some reading strategies in reading practice. It also means that it is necessary for English teachers to take into consideration the reading strategies suitable for the students in their reading classes.

A psychological disturbance caused by letters in double image was termed as'letter sickness'.The effects of stimulus exposure time and letter familiarity on the letter sickness were measured to test a hypothesis that disturbances in eye movement and recognition stages is the cause of letter sickness.Letter sickness incteased significantly as stimulus exposure time lengthened from 50ms,100ms,to 3000ms.It was also significantly higher with familiar Hangul letters as compared with less familiar foreign letters and meaningless words as compared with meaningful words,respectively.These experimental findings imply that letter sickness is caused by the failure of adjusting eye movements to dismiss the double images.that the more familiar the letters.the more strongly the letter-identification process is commotted,resulting in the increased effect of disturbance from double image.and that the disturbance effect of double image is amplified when it is hard to extract the meaning from familiar letters.An experiment where subjects were made to learn Braille-like symbols consisting of 6 dots to test the hypothesis that the stronger the tendency to process the meaning of a symbol,the stronger becomes letter sickness due to double image,also showed that letter sickness significantly increased as a function of learning.

Outsourcing, importing of publishing metadata and revitalizing copy cataloging have reduced importance of traditional cataloging. Request of interoperability between other communities and business integration of related system also have changed the meaning of library catalog. Furthermore, newly declared principle and rules are totally different to existing AACR, MARC, measures to cataloging education for next generation seems to be urgently needed. In this study, firstly put together a series of discussion about future cataloging and new role of cataloging librarian, and secondly basis on it, suggest direction of cataloging education course which divided two sectors. One is for students who are undergraduated, and another is for current cataloger at working level. In basic training, it should contain principle of knowledge organization and diverse resources and its relationship, encoding scheme and its practice. The other hand, in re-education training, it should include that re-recognition about new concept of bibliographic world, changing vocabulary and encoding scheme, furthermore metadata scheme about diverse resources which library have accepted, and its integration.
