  • This study presents a recurrent compensatory fuzzy neural network (RCFNN) for dynamic system identification. The proposed RCFNN uses a compensatory fuzzy reasoning method, and has feedback connections added to the rule layer of the RCFNN. The compensatory fuzzy reasoning method can make the fuzzy logic system more effective, and the additional feedback connections can solve temporal problems as well. Moreover, an online learning algorithm is demonstrated to automatically construct the RCFNN. The RCFNN initially contains no rules. The rules are created and adapted as online learning proceeds via simultaneous structure and parameter learning. Structure learning is based on the measure of degree and parameter learning is based on the gradient descent algorithm. The simulation results from identifying dynamic systems demonstrate that the convergence speed of the proposed method exceeds that of conventional methods. Moreover, the number of adjustable parameters of the proposed method is less than the other recurrent methods.

  • In this paper, We Designed the torque compensatory controller for robot manipulator using modified chaotic neural networks with self feedback loop. The proposed torque compensatory controller compensate torque of the PD controller. In order to estimate the proposed controller, we implemented to the Cartesian space control of three-axis PUMA robot and compared the simulation results with recurrent neural networks(RNNs) controller. Simulation results show that the learning error drastically decrease at on-line learning. The proposed CNNs controller shows much better control performance and shorter processing time compared to the recurrent neural network controller in the robot trajectory control.

  • Purpose - This paper aims at exploring the effects of failure types such as failure in promotion orientation and failure in prevention orientation on consumers' consumption behavior, and the moderation role of lay theories in the effects. Research design, data, and methodology - This study employed 2 between-subject designs(failure in promotion orientation vs. failure in prevention orientation) and also 2 (failure in promotion orientation vs. failure in prevention orientation) with implicit self as the within-subject. Chinese consumers participated in the empirical study, and to verify the hypotheses ANOVA, T-test and regression analysis were used. Results - Consumers were more likely to choose adaptive consumption behavior rather than compensatory consumption behavior when they were encountered with failure in promotion orientation versus failure in prevention orientation. Lay theories did play the moderation role in the effect of failure types on consumption behavior. The incremental theorists who think that effort is an important way to accomplish their learning goals showed more willingness to conduct compensatory consumption behavior rather than adaptive consumption behavior. Conclusions - Marketers should put more attention on the ways by which their products can help consumers self-improve when consumers encounter with failure. They should also be aware of the importance of consumers' mindsets when designing and developing advertising messages.

  • Learning disorders are diagnosed when the individual's achievement on standardized tests in reading, mathematics, or written expression is substantially below that expected for age, schooling, and level of intelligence. Subtypes of learning disorders may be classified into two groups, language-based type learning disorders including reading and writing disorder, and nonverbal type learning disorder (NLD) such as those relating to mathematics & visuospatial skills, and those in the autism spectrum. Converging evidence indicates that reading disorder represents a disorder within the language system and more specifically within a particular subcomponent of that system, phonological processing. Recent advances in neuroimaging technology, particularly the development of fMRI, provide evidences of a neurobiological basis for reading disorder, specifically a disruption of two left hemisphere posterior brain systems, one parieto-temporal, the other occipito-temporal. The former is the reading system for beginner reading, the latter for skilled reading. Compensatory engagement of anterior systems around the inferior frontal gyrus(Broca's area) and a posterior(right occipito-temporal) system is noted in persistent poor readers in long-term follow up study. The theoretical model proposed to explain NLD's source is not right hemisphere damage, but rather the white matter model. The working hypothesis of the white matter model is that the underdevelopment of, damage to, or dysfunction of cerebral white matter(long myelinated fibers) is the source of this disorder. The role of an evidence-based effective intervention in the remediation of children with learning disorder is discussed.

  • In this research, 'Construction Technology and Environment' units in 12 different technology home economics textbooks for 1st~3rd year middle school students under the 2009 Revised Educational Curriculum and the content system of textbooks were analyzed based on Reigeluth's elaboration theory, and the following conclusions were derived. First, each of the 12 different textbooks presented the elaboration process by procedural method and composed the content system. Second, the 'Construction Technology and Environment' unit presented many 'Thought Opening' as the systematization strategy of advance learning ability, and 'Unit Summary' presented at the end of the unit as the use strategy of the summarizer was presented preponderantly. In addition, 'Learning Objective' that represents the degree of achievement of the students after learning the unit was presented most as the use strategy of the synthesizer although there are differences in terms. In all of the textbooks, 'Figure,' 'Table,' 'Diagram', and 'Explanation of Terms' were used, and particularly, in the vitalizer strategy of the cognitive strategy, overwhelmingly greater number of 'Figure's, compared with all other elements, were presented as the vitalizer strategy of cognitive strategy. Finally, 'Compensatory Learning,' and 'In-depth Study' were presented as the learner control strategy in each of the 4 different textbooks, and there was one textbook that presents the term 'Supplement Reinforcement' in which compensatory learning and in-depth learning were integrated. Third, the metaphor utilization strategy among the 7 teaching strategies of the elaboration theory was hardly used in the composition items in units of textbooks.

  • With the popularity of online learning, intelligent tutoring systems are starting to become mainstream for assisting online question practice. Surrounded by abundant learning resources, some students struggle to select the proper questions. Personalized question recommendation is crucial for supporting students in choosing the proper questions to improve their learning performance. However, traditional question recommendation methods (i.e., collaborative filtering (CF) and cognitive diagnosis model (CDM)) cannot meet students' needs well. The CDM-based question recommendation ignores students' requirements and similarities, resulting in inaccuracies in the recommendation. Even CF examines student similarities, it disregards their knowledge proficiency and struggles when generating questions of appropriate difficulty. To solve these issues, we first design an enhanced cognitive diagnosis process that integrates students' affection into traditional CDM by employing the non-compensatory bidimensional item response model (NCB-IRM) to enhance the representation of individual personality. Subsequently, we propose an affection-enhanced personalized question recommendation (AE-PQR) method for online learning. It introduces NCB-IRM to CF, considering both individual and common characteristics of students' responses to maintain rationality and accuracy for personalized question recommendation. Experimental results show that our proposed method improves the accuracy of diagnosed student cognition and the appropriateness of recommended questions.

  • This study attempted to investigate household's private educational expenditure that aggravates a burden on households by using the data from the 2014 Private Education Survey published by Statistics Korea. The effects of purposes of private education and participation in an after school program that is pushed by the government on household's private educational expenditure were analyzed. The major findings were as follows. First, the major purposes of private education lean toward preparing to enroll in school and relieving parents'uneasiness rather than prior learning Second, according to the purposes of private education, the differences of the private educational expenditure were verified. Households spend the highest level of private educational expenditure for the purpose of preparing to enroll in school contrary to the lowest level, which was for the purpose of compensatory learning. Third, participation in an after school program that is regarded as a method of moderating households' private education burden, had a positive effect on reducing private educational expenditure. Forth, private educational expenditure was influenced by the purposes of private education and participation in an after school program. In 2014, the Korean government enforced a law that prohibits schools'education in advance (prior learning) and regulates private educational institutes'advertisement about prior learning. Regarding this regulation, this study aimed to investigate the purposes and expenditure of private education to provide an empirical reference to determine the improvement of related policies.
