At what level of orthographic representation is phonology linked in thelexicon? Is it at the whole word level, the syllable level, letter level, etc? This question can be addressed by comparing the two scripts used in Korean, logographic Hanmoon and alphabetic/syllabic Hangul, on a task where judgements must be made about the phonology of a visually presented word. Four experiments are reported using a "homophone decision task" and manipulating the sub-lexical relationship between orthography and phonology in Hanmoon and Hangul, and the lexical status of the stimuli. Hangul words showed a much higher error rate in judging whether there was another word identically pronounced than both Hangul nonwords and Hanmoon words. It is concluded that the relationship between orthography and phonology in the lexicon differs according tn the type of script owing to the availability of sub-lexical information: the process of making a homophone derision is based on a spread of activation exclusively among lexical entries, from orthography to phonology and vice versa (called "Orthography-Phonology-Orthography Rebound" or "OPO Rebound"). The results are explained within the mulitilevel interactive activation model with orthographic units linked to phonological units at each level.

The fusion of virtual and reality and the revolution of gamification are beginning in human culture. As the quaternary industrial revolution enters the era, major developments of convergence main content games are expected as human-made play products. Now that we need a diverse game IP, we need a methodology that makes it easy to approach game scenario creation. The creation of the game scenario has a very large difference due to interactivity with the general video scenario. Therefore, without interactive knowledge, it is difficult to challenge game scenario creation. In this paper, 'Game Scenario Creation List' was created in order to lower the barriers to entering game scenario creation. I hope that this paper will be even a little positive for the development of game contents.

In this paper, I will propose a Custom-made Suit Production System. The system does not only help the customers to edit and measure their size by creating the landmarks in the 2D human body images which is taken from the camera, but it also visualizes the virtual cloth by using the landmarks and the modeling data of the virtual cloth. In this system is a new technology for the digital and the automation which is not handmade way of using Custom-made Suit industry. It will be generally useful in the various contents of the clothing industry.

Recently researches about multi-modal system has been studied widely and actively, Such multi-modal systems are enable to increase possibility of HCI(Human-computer Interaction) realization, enable to provide information in various ways and also enable to be applicable in e-business application, If ideal multi-modal system can be realized in future, eventually user can maximize interactive usability between information instrument and men in hands-free and eyes-free, In this paper, a new multi-modal browsing system using Java RMI as communication interface, which integrated by HTML browser and voice browser is suggested and also English-English dictionary search application system is implemented as example.

In this paper, we suggest a haptic mouse system as an immersive interface between virtual environment and a human operator. The proposed haptic mouse creates vibrotacitle and thermal sensation to increase the immersion. The vibrotactile module is composed of eccentric motors and a solenoid actuator, and the thermal module consists of a thin-film resistance temperature detector and a Peltier thermoelectric heat pump. In order to evaluate the proposed haptic mouse system, we develop a simple racing game and conduct an experiment. The result of the experiment shows that the proposed haptic mouse system can improve the sense of reality in virtual environment and can be used as an effective interface between virtual environment and a human operator.

This paper presents a new system to estimate the head pose of human in interactive indoor environment that has dynamic illumination change and large working space. The main idea of this system is to suggest a new morphological feature for estimating head angle from stereo disparity map. When a disparity map is obtained from stereo camera, the matching confidence value can be derived by measurements of correlation of the stereo images. Applying a threshold to the confidence value, we also obtain the specific morphology of the disparity map. Therefore, we can obtain the morphological shape of disparity map. Through the analysis of this morphological property, the head pose can be estimated. It is simple and fast algorithm in comparison with other algorithm which apply facial template, 2D, 3D models and optical flow method. Our system can automatically segment and estimate head pose in a wide range of head motion without manual initialization like other optical flow system. As the result of experiments, we obtained the reliable head orientation data under the real-time performance.

This study aims to examine how home child care allowance influences a mother's choice of child care type. To accomplish this goal, we surveyed 432 mothers who had at least one child under 5 years old. The data were analyzed by frequencies, percentages, means and binomial logistic regressions. The results showed that unemployed mothers and mothers with younger children had a high tendency to choose home child care allowance instead of child care subsidy. Second, mother's employment status, age of first child and an interactive term of mother's employment status and home child care receipt influenced a concordance between an ideal and actual child care type. Unemployed mothers and mothers with younger children were more likely to experience a concordance between their ideal and actual types of child care. By investigating how home child care allowance affects the right of choice in child care type, this study provides empirical information to policy makers and researchers and contributes to develop cash-benefit policies for families with young children.

The study is to investigate mothers' parental beliefs about child development and the children's developmental tasks, and to explore the relationship between mother's parental beliefs and child-rearing behaviors. The subjects are 113 pairs of 4- to 5-year-old children and their mothers. For measuring maternal beliefs about child-development, 'beliefs about development scale' and 'child-rearing beliefs scales' were used. For mother's child-rearing behaviors, 'child rearing behavior observation scale' was used. The main results were: first, mothers value the cognitive theory and 'autonomous behavior' higher than 'conforming behavior' in developing their children. Second, there were no differences in mother's parenting beliefs in the factors of 'gender of their children' and 'maternal job status', while there were significant differences in maternal beliefs according to the levels of mother's education and family income. Third, sub-scales of their parenting beliefs were correlated with interactive behaviors between them and their children. The more mothers put importance on cognitive theory and children's autonomous behaviors, the more their supportive child-rearing behaviors during child-mother task solving situations were showed.

This paper presents a task planning system for a steward robot, which has been developed as an interactive intermediate agent between an end-user and a complex smart home environment called the ISH (Intelligent Sweet Home) at KAIST (Korea Advanced Institute of Science and Technology). The ISH is a large-scale robotic environment with various assistive robots and home appliances for independent living of the elderly and the people with disabilities. In particular, as an approach for achieving human-friendly human-robot interaction, we aim at 'simplification of task commands' by the user. In this sense, a task planning system has been proposed to generate a sequence of actions effectively for coordinating subtasks of the target subsystems from the given high-level task command. Basically, the task planning is performed under the framework of STRIPS (Stanford Research Institute Problem Solver) representation and the split planning method. In addition, we applied a state-partitioning technique to the backward split planning method to reduce computational time. By analyzing the obtained graph, the planning system decomposes an original planning problem into several independent sub-problems, and then, the planning system generates a proper sequence of actions. To show the effectiveness of the proposed system, we deal with a scenario of a planning problem in the ISH.
