In a goal-oriented dialogue, speakers' intentions can be represented by domain actions that consist of pairs of a speech act and a concept sequence. Therefore, if we plan to implement an intelligent dialogue system, it is very important to correctly infer the domain actions from surface utterances. In this paper, we propose a statistical model to determine speech acts and concept sequences using conditional random fields at the same time. To avoid biased learning problems, the proposed model uses low-level linguistic features such as lexicals and parts-of-speech. Then, it filters out uninformative features using the chi-square statistic. In the experiments in a schedule arrangement domain, the proposed system showed good performances (the precision of 93.0% on speech act classification and the precision of 90.2% on concept sequence classification).

Purpose: The purpose of this study was to examine the parenting of mothers with infants and preschoolers in an effort to determine types of parenting. Methods: The 32 participating mothers were interviewed and from the content of the interviews, their parenting was analyzed. Statements were categorized and analyzed according to the selected procedure. Results: The parenting of mothers was classified into positive reinforcement and negative reinforcement, including 55 significant statements and 14 categories. Positive reinforcement was categorized as frequent skin contact, giving pleasure, spending a lot of time with children, improving children's self-esteem, being sensitive to children's needs, realistic discipline, developing independence, listening to children, and understanding and respecting children's feelings. Negative reinforcement was categorized as overprotection, inconsistent attitude, negligence, negative educational behavior, and emphasis on obedience. Conclusion: These results suggest that systematic education should be provided for mothers to increase their ability to provide good parenting. It is expected that the findings of this study would be useful in the development of efficient educational programs.

This study explores high school gifted students' perception of cheating in school using the concept mapping method. The map shows the gifted students' concept structure and the different perception between gifted and non-gifted students on cheating. For the purpose, 63 high school gifted students participated at the brainstorming stage to gather the possible related statements. Finally, 64 statements were confirmed and these were divided and evaluated by 13 focus group students. Then, they were analyzed by multidimensional scaling and processed by hierarchical cluster analysis. The results compiled from this procedure show that high school gifted students' perception of cheating is classified into five clusters: "unacceptable cheating behaviors of friends", "an inseparable relation among social structure, giftedness and cheating", "conflict, coping skills, and tolerance related to the cheating", "immorality in one's inner person" and "the judgement based on morality and social justice". In addition, 150 gifted students and 160 non-gifted students checked the degree of agreement to each statement with the likert 6 points scale and the result showed that there was no significant difference in two clusters, "unacceptable cheating behaviors of friends" and "the judgement based on morality and justice", while it turned out that there were significant perception gaps in three clusters, "inseparable relation among social structure, giftedness and cheating", "conflict, coping skills, and tolerance related to the cheating" and "immorality in one's inner person". Implications of the study related to the gifted students' moral behaviors were discussed in depth.

This paper is a research of gaze analysis for measuring task switching behavior at multiple windows in GUI of windowing system. Previous methods that define area of interest for categorizing gaze had difficulties to define dynamic content that disappears or changes over time. On the other hand, this study suggests a new method to categorize gaze that defines Area of interest in a unit of window during the eye tracking experiment. In this paper, we constructed the conception of WOI(Window of Interest) in GUI of windowing system. Therefore, we developed a system using an eye tracker device and implemented a number of experiments. In addition, we analyzed the number of task switching and proportion of watched content. The method in the study comprehend from previous researches as it can measure and analyze the multi-tasking behaviors using multiple numbers of windows.

The mirror neuron system in the cerebrum, which are handled by visual information-based imitative learning. When we observe the observer's range of mirror neuron system, we can assume intention of performance through progress of neural activation as specific range, in include of partially hidden range. It is goal of our paper that imitative learning is applied to 3D vision-based intelligent system. We have experiment as stereo camera-based restoration about acquired 3D image our previous research Using Optical flow, unscented Kalman filter. At this point, 3D input image is sequential continuous image as including of partially hidden range. We used Hidden Markov Model to perform the intention recognition about performance as result of restoration-based hidden range. The dynamic inference function about sequential input data have compatible properties such as hand gesture recognition include of hidden range. In this paper, for proposed intention recognition, we already had a simulation about object outline and feature extraction in the previous research, we generated temporal continuous feature vector about feature extraction and when we apply to Hidden Markov Model, make a result of simulation about hand gesture classification according to intention pattern. We got the result of hand gesture classification as value of posterior probability, and proved the accuracy outstandingness through the result.
