The driver's decision making (e.g. route choice) is a typical decision making with an uncertainty. In this paper, we investigate the effect of route guidance information on driver's route choice and learning behavior and analyse the potential of information system in a road network in which traffic flows follow random walk. A Simulation performed focuses on the relationship among the network wide performance, message receiving rates and driver's learning mechanism. We know that at high levels of message receiving rates, the network-wide performance may get worse. However, at low levels of receiving rates, we found that the travel time when guidance information is provided decrease compared to the cases when no pubic information is provided. Also, we found that the learning parameter of the learning mechanism model always changes under nonstationary traffic condition. In addition, learning process of drivers does not converge on any specific value. More investigation is needed to enlarge the scope of the study and to explore more deeply driver's behavior.

Purpose: This study was performed to identify the relationship between stress perceived by middle school students and social support level and to investigate the factors affecting middle school students' smoking behavior. Method: The data was collected from four hundred and thirteen students of one boys' middle school and one girls' middle school. Data were analyzed by using SPSS 11.5 Win Program. Result: Smoking rate was higher in girls than boys. The factors affecting smoking behavior were drinking (OR=67.62, P<0.01), having one parent or no parents(OR=9.98, P<0.05), and higher material support(OR=4.67, P<0.05). Conclusion: This results showed that smoking prevention program is needed for girls' middle school students. To prevent smoking, teachers should help students to cope with stress from schools and their environments with careful guidance, and organized support for the student with one parent or no parents should also be established. Furthermore, guidance in student's relationships with peers is needed regarding appropriate allowance, drinking, or substance use.

Individuals with special needs include those with behavioral issues, developmental disorders, cognitive disorders, congenital or genetic disorders, or systemic disease. These conditions may place them at increased risk for oral diseases. Dental management of patients with special needs require in-depth understanding of the background of disability and available behavioral guidance theories. Therefore dental team members need more training in the theory and practice of behavior management principles, which might lead to a clinical experience that is more respectful of the dignity and independence of patients with special needs. The dental professional should be flexible to modify the behavior management approach according to the individual patients needs. Also a family/care-giver centered approach based on their preferences and concerns, the patient's challenging behaviors, and related medical problem can serve to improve the treatment planning and oral health management of dental patients with special needs. This article focuses on uncooperative behavior and behavior management, which help practicing dentists to understand their role in the care of patients with special needs.

The purpose of this study was to investigate the relationship between mothers' parenting behavior and preschoolers' attachment security to their mother and preschoolers' social competence. The sample were 44 mothers and their 49-56 months old preschoolers. The instruments for this study were the modified IPBI(Iowa Parent Behavior Inventory: Mother Form), the Attachment Q-set by Waters and the modified ISCS(Iowa Social Competence Scales: Preschool Form). The data were analyzed by frequency, t-test, Pearson's r, and Multiple Regression Analysis. Major findings were that the responsive maternal parenting behavior was positively related to the preschoolers' attachment security. The guidance of maternal parenting behavior was positively related preschoolers' social activator of social competence. And there were significant correlations between the preschoolers' attachment security and social competence. The attachment security was positively related to the socially activating and cooperative competence.

The purpose of present study is to investigate children's attitude toward reading, reading method, reading environment, reading volume, and then to compare the results obtained by sex, area and grade. The tool used in this survey was a questionaire designed specially by the investigator. The questionaire was distributed to 1339 children selected at the descretion of the investigator with due consideration of sex, area(large city, medium city and rural community) and grade (from 2nd grade of primary school to 2nd year of middle school). The results of this study are summerized as follows : 1) Regional difference was observed in respect of the followiug : Awareness on reading, motivation for reading, reading method, activity after reading, number of books collected, reading guidance, how to obtain books to read, monthly reading volume, and reading tendency. 2) Also difference by grade was observed in respcet of the following ; Activity after reading, reading guidance, monthly reading volume and reading tendency. The following conclusions have been made based on the results of the survey: 1) The children's attitude toward reading and reading method may be considered favorable while reading environment is not satisfactory yet. Especially, reading environment of school children in medium cities and rural communities is worse than that of large cities. 2) No difference by sex was observed in respect of attitudes toward reading, reading method, reading environment and reading volume while difference by sex was observed in respect of reading tendency. The followings are recommended based on the results of survey: 1) To establish and carry out a comprehensive program for the improvement of reading environment of the school children in medium cities and rural communities. 2) To improve and substantiate school library facilities and design a proper guidance program to have children utilize school library to the maximum extent. 3) To contemplate on the consolidated measures for reading behavior survey.

A mathematical tension model for a moving web in a multi-span web handling system was derived and validated by using a simulator which includes unwinder, driven roller, winder, load cells, controllers, etc. A tension controller was designed to compensate tension disturbances generated by velocity changes of the unwinder and driven roller. From experimental results it was proved that the tension model properly expressed the tension behavior of a moving web for specific conditions. The distributed tension controller designed by using the pole-placement technique compensated the tension disturbances transfered from upsteram tension variation. Interactions between web spans including "tension transfer phenomenon" were clearly confirmed through the study. A mathematical model of lateral motion of a moving web was verified also by using the same experimental apparatus which includes displacement type guidance systems. And a feedforward control strategy was designed for more accurate control of the lateral motion of a moving web, which utilize a measured signal of the lateral displacement of web in a previous span and a more correctly identified mathematical model to estimate the disturbance of lateral motion from the previous span. This approach was turned out to be effective in improving the performance of the guidance system for more wide range disturbances.
