In this paper, we have developed page level input system of the character reading aid for the blind. Input toys)ems arse consisted with 512 pixels line image sensor, optical lento, digital interface for the computer and its control software. Input buffer size of the computer memory that for the single scanning of printed matters Image is 64kB. Image patterns of the reading characters which stored in system memory are converted to tactile character patterns that would be output to the bimorph tactile sensor by software control.

In order toidentify the daily activities of five-year-old children in a daycare center, the 23 children in "Yellow" class at "Yellow" Daycare Center were observed for seven months. Research was informed by a qualitative approach. Findings were that : children were rigidly attached to a time frame built into their daily classroom schedule, arranged by time and classroom space allotted to each unit. The meaning to the children was to be found in their "busyness;" they were very busy finalizing activities imposed by teachers within a short period of time. They spent most of their time moving about from one space to another within the classroom, and they played with their mostly artificial toys under rules set by the teacher.

Internet was once used to link ideas, then people and now it is starting to connect all things. IoT constitutes a good paradigm to enable people to design and modify things, and then share their designs and modifications. Through the internet, things nowadays are able to exchange raw data and information, thus enabling the development of a new class of interconnected smart objects. Smart building block toy systema are a newly proposed concept that combines internet technology into educational blocks. It is composed of the IoT environment that has attracted attention recently. In this paper, we design a system using starUML, one of the program development tools in the system design process. Educational content can be shared to learners via the proposed service of the IoT, while also being interesting for young child learners.

An emotionally modeled robot is dealt in this paper. The emotional model is required especially in the entertainment robot. Recently, the entertainment robots have been developed as the next generation of electronic toys. They require several capabilities such as perceiving, acting, communication, and surviving. The owner recognizes the communication with a entertainment robot by observing its expression and reaction. The expression is realized by emotion-based actions based on moving, dancing, sounding, speaking, and lighting. Therefore, we propose an emotional modeling algorithm, using the fuzzy logic system, in this paper. Good performance of the algorithm is confirmed by the result of a simulation.

R/C helicopter has been used to several fields of military affairs, investigation searching and toys because it has small size hovering and vortical take-off characteristics etc. Therefore it needs more realizable control method. The paper introduces simulation and experimental results for control of a helicopter training simulator by self tuning control method. To realize the disturbance rejection and the given reference tracking, a least common multiple polynomial between the reference and disturbance model polynomials is operated to the plant model. The effectiveness of the method is shown by simulation and experimental results for a helicopter training simulator with two degree of freedom.

Mothers of 113 Korean toddlers completed Toddler Behavior Assessment Questionnaire(TBAQ) and Child Rearing Practice Report(CRPR). Observations of mother-child dyads in novel situations involving unfamiliar settings and adults assessed child's behavioral inhibition. Nonsocial inhibition were measured by the amount of time each child spent in physical contact with his/her mother in free-play episodes. Adult-social inhibition was based on child's behavior when an unfamiliar adult requested that the child approach her as she presented them with toys or activities. Results showed that TBAQ Social Fearfulness was positively associated with nonsocial and adult-social inhibition. TBAQ Pleasure was correlated negatively and TBAQ Anger Proneness positively correlated with adult-social inhibition. An interaction effect showed that child's social fearfulness and mother's overprotective behaviors affected adult-social inhibition. The regression model explained 31% of the variance.
