The purpose of this case study is to examine how group rhythmic playing can help enhance imitation skills for 3 children with developmental disabilities aged between 30-50 months. The program was composed of social musical play, the therapist's imitating the way young children played musical instruments, and the young children's imitating the way the therapist played musical instruments. Every session was videotaped, and the researcher and two music therapists checked the videotaped sessions to ensure the reliability of findings. The case study demonstrated the following results. First, the three young children who participated in the playing of rhythmic musical instruments showed an increase in imitation behaviors. Second, the infants exhibited the greatest change from 1 beat imitation according to the degree of difficulty of group rhythm musical instrument demonstrated. Third, the most radical change in the infants' ability to imitate appeared in Sessions 3-7 where the therapist imitated the operation and a performance of the infant. In conclusion, the activity of playing rhythmic musical instruments in a group generated improvement in the imitation ability of young children with developmental disabilities.

Work zone traffic control is of keen interest because both traffic operations and safety performances are directly affected by traffic management methods. In particular, work zone traffic on two-lane roads needs to be managed in more efficient and safer manners due to its unique characteristics of alternative right-of-way assignment. This study developed a dynamic control algorithm that can be used for real-time operations of two-lane work zone traffic. The performance of the developed algorithm was evaluated by VISSIM microscopic traffic simulator. An applied programming interface (API) based program was developed to plug-in the control algorithm onto the simulator. The results demonstrated the feasibility of the proposed control algorithm for two-lane work zone.

This study deals with the operational effectiveness of roundabout. The roundabout is currently under consideration in our country depending on the result of existing researches, that the roundabout decreases delay and is environmentally friendly compared to the signalized intersection. The purpose of the study is to analyze the operational effectiveness of the roundabout by the change of pedestrian traffic volume. In pursing the above, this study gave particular emphasis to designing a network of roundabout, developing some scenarios for analysis including both entering traffic volume and pedestrians volume, and comparatively analyzing the average controlled delay time per vehicle. In this study, VISSIM model was used as a tool for traffic simulation. The main results are as follows. First, as a result of analyzing a traffic delay based on the pedestrian traffic volume, pedestrian traffic volume was analyzed to have a great impact on the roundabout operation. Second, the more pedestrian traffic volume were evaluated to indicate the more traffic delay. When the entering volumes with 1,000persons/hour (pedestrian volume) were more than 800pcph in the single-lane and 1,600pcph in the double-lane roundabout, the operational efficiencies of signalized intersections were evaluated to be better than those of roundabouts.

It is widely known that individuals with mental retardation (MR) and Down's syndrome (DS) often develop early onset periodontal diseases. In this study, the prevalence of periodontopathic bacteria in MR persons and DS patients was compared with normal persons. Plaque index and gingival index were measured. Five periodontopathic bacteria, Actinobacillus actinomycetemcomitans. Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola, Fusobacterium nucleatum were surveyed in subgingival plaque samples by the polymerase chain reaction. Results : 1. Plaque index and gingival index were higher in MR persons group and DS patients group than normal persons group (p<0.05). 2. The prevalence of periodontopathic bacteria in normal persons group were lower than that of MR persons group and DS. Significant differences were observed in the prevalence of P. gingivalis, T. denticola and A. actinomycetemcomitans(P<0.05). 3. Prevalence of P. gingivalis(5.9%) at age 8-10 was lower than other ages in normal persons group, and its prevalence increased with age Prevalence of P. gingivalis, T. denticola and A. actinomycetemcomitans at MR persons group and DS patients group were higher than those of same ages of normal persons group. 4. Plaque index was associated with T. denticola and gingival index was associated with T. denticola and A. actinomycetemcomitans(P<0.05). These results suggested that plaque index, gingival index and prevalence of periodontopathic pathogens, especially P. gingivalis, T. denticola and A actinomycetemcomitans in DS patients group and MR persons group are higher than those of normal persons group.

The purpose of the present study was to examine whether Interpersonal Cognitive Problem Solving(ICPS) skill training would enhance interpersonal solving skills and behavioral adjustment of mildly mentally retarded adolescents in the junior and high school. The program used in the present study was shortened and adapted for mildly retarded adolescents from Shure and Spivack(1982) program which was developed to improve the adjustment of children in the intermediate grades 5-6. The subjects were 22 mildly retarded adolescents, and they were assigned to either the experimental(11) or the control group(11). The experimental group were given ICPS training 4 times a week over a period of 8 weeks with a total of 32 sessions in all. The results showed a significant improvement of alternative thinking and consequential thinking in the experimental group compared with the control group. With regard to behavioral ratings by the parents and teachers, there were no significant differences between the groups. The results indicated that the training was effective in increasing the ability to generate alternative solutions and to predict consequences, but the significant improvement of interpersonal cognitive problem solving skills did not lead to noticeable improvement in behavioral adjustment. It was suggested that a longer training period for over-learning, concomitant parent education program, and more behaviorally oriented social skill training combined with the cognitive approach would yield significant training effects, maintenance and transfer.

This study analysis traffic phase order alternatives to maximize throughput. According to theoretical analysis alternative2(EW: left turn after through, NS: through after left turn) and alternative5(EW: through after left turn, NS: left turn after through) can minimize the maximum delay. Both alternatives split the phase that have the same destination link under the whole cycle length. This shows that phase order alternative can effect to the fully saturated intersection. In side of simulation analysis by microscopic traffic simulator PTV VISSIM F 7.0, each phase order alternatives can't effect throughput under the non saturated condition. However under the saturated condition, the average controlled delay of the intersection has been changed by phase order alternatives. The simulation analysis shows that alternative2 and alternative5 increase throughput 3.8% to 5.1% under the saturated condition.

This study aims to analyze the causes of the disabled people's fear of crimes and to provide the implication to relevant policies. For this, we scrutinize how the disabled perceive the fear toward felonies and the police action. Further, we empirically tested how police action and their recognition toward it affects the fear toward crimes, on the basis of collective efficacy and victimization which is believed to have effects on people's fear of crimes. As the physically disabled are incompetent to respond to the questions, we survey 122 person with physical disability for 25 branches of Seoul Association of Person Physically Disabled. Our regression results show negative correlations between collective efficacy and fear of crimes, which is in accord with preceding researches of the non-handicapped. While indirect victimization shows positive correlations with their fear toward crime, it is ot statistically significant in conventional confidence level. Contrarily, direct victimization shows positive correlation with it, and the coefficient is different from zero in conventional level. As it is proven from preceding studies, confidence in police action and their perception toward it has negative correlations with their fear of crimes.
