The study of pedestrian behavior covers wide topics, including way finding, choice and decision make, as well as spatial cognition and environmental perception. To address the problem, simulation is now put forward as suitable technique and method for analyzing human spatial behavior. In the paper we present a development architecture for simulating tracking pedestrian in a distributed environment. We introduce and explore the potential of using mobile agent-enabled distributed implementation model as a tool for development and implementation of the simulation. Three kinds of mobile agents are designed for implementation of managing and querying data of pedestrian. Finally, simulation result of JR 10,000 passengers’ movement is developed and implemented as a case study.

What is the foundation of mathematical thinking? Is it logic based symbolic language system? or does it rely more on mental imagery and visuo-spatial abilities? What kind of neural changes happen if someone's mathematical abilities improve through practice? To answer these questions, basic cognitive processes including long term memory, working memory, visuo-spatial perception, number processes are considered through neuropsychological outcomes. Neuronal changes following development and practices are inspected and we can show there are neural networks critical for the mathematical thinking and development: prefrontal-anterior cingulate-parietal network. Through these inquiry, we can infer the answer to our question.

Our study focuses on the implementation of IS development methodology as the innovation of IS organization. We have two main research objectives. We Intend to understand the critical factors affecting the implementation process of IS methodology. We also intend to deeply analyze the relationship among the implementation processes of methodology. The whole innovation process is divided into detailed four levels tilth dynamic and evolving Point of clew a cognition level, an adoption level, an acceptance level and an usage level. The results of our study are as follows. The main factors affecting initiation level of the IS methodology are the innovativeness of IS members, the existence of champion manager, training, the existence of IS performance gap, executive supports for IS organization, and the relative advantage of IS development methodology At the Implementation level, It is understood that the existence of champion manager executive supports, training and the relative advantage of innovation are the main factors. However, the complexity of Innovation is a megative factor about the quality of accepting and using the methodology In Innovation process. In performing the Innovation process, the Previous level gives very notable affection to the continuous next level. However it's also understood that positive attitude of adoption level does not directly affect the quality of using Innovation. Therefore, IS managers must pay attention to manacle each level of the Innovation Process to successfully accomplish the Implementation of IS methodology.

In this study, authors investigated the attachment of toddlers to their mothers and teachers and overall development based on their gender differences. The subjects of the study are 80 toddlers who are 25~36 months, their mothers, and teachers. We analyzed our data using t-test and two way ANOVA, and the results are as follows. First, the groups categorized by the types of the attachment between the toddlers and the mothers and the gender difference demonstrated the developmental distinctions, respectively. The interactional effects of the two factors emerged in communication and basic living. Second, the groups categorized by the types of the attachment between the toddlers and the teachers and the gender difference demonstrated the developmental distinctions, respectively. The interactional effects of the two factors emerged in gross motor skills, fine motor skills, and cognition. Third, with respect to the types of multiple attachments to mothers and teachers, toddler development brought meaningful differences. We discussed the importances of the attachment of the toddlers and the role of teachers based on the results of our research and proposed future projects and suggestions.

It suggests a closet design for infants in consideration of space utilization, furniture arrangement, and goods storage by integrating a baby's closet and toy chest, which was used for storage of baby's toys and play instrument. For this, it conducted and analyzed data research on the infants' toy chests in the domestic and overseas market and based on such approach, the colors that helped development of infants' cognition and emotion were selected while suggesting familiar animal characters for infants. Without considering separate arrangement of furniture and toy chest within limited space, it allowed space utilization and provided enough storing space. Also, the attached ball casters enabled easy carry of the closet and with this function, it helps infants arrange and store goods by themselves so that making them feel a sense of accomplishment. For effective spatial utilization as well as security of its genuine storage function, the closet and toy chest were combined in this study. Thus, it is believed that development of such multifunctional furniture will suggest the direction of researches on domestic furniture development that are conducted to maximize utilization of residential space for the people living today.

Three types of learning and memory tests (Morris water maze, active and passive avoidance) were performed in rats following intracerebroventricular infusion of ethylcholine aziridium (AF64A). In Morris water maze, AF64A-treated rats showed the delayed latencies to find the platform iron 6th day after the infusion. In pretrained rats, AF64A caused the significant delay of latency at 7th days but not 8th day. In the active avoidance for the pretrained rats, the escape latency was significantly delayed in AF64A-treatment. The percentages of avoidance in AF64A-treated rats were less increased than those in the control. Especially, the percentage of no response in the AF64A-treated rats was markedly increased in the first half trials. In the passive avoidance, AF64A-treated rats shortened the latency 1.5 h after the electronic shock, but not 24 h. AF64A also caused the pretrained rats to shorten the latency 7th day after the infusion, but not 8th day. These results indicate that AF64A might impair the learning and memory. However, these results indicate that the disturbed memory by AF64A might rapidly recover after the first retrain. Furthermore, these results suggest that AF64A may be a useful agent for the animal model of learning for Spatial cognition .
