The purpose of this study was to propose information services for people with disabilities in the culture and art complex. As a research method, group interviews were conducted. Data were collected from three different groups of people with physical disabilities, hearing impairments, and visual impairments in order to investigate specific information services for these groups of people. The results of the information services needed were indicated, based on four sections: the center web pages, information desk, orientation area, and information search area. Specifically, the results showed that more active supports would be provided at the information desks for people with hearing impairments and visual impairments as well as facilities for people with physical disabilities. In the orientation area, special equipment would be provided for people with hearing impairments and visual impairments, and exclusive seats for wheelchair users. For further studies, a detailed research about the information behavior for visitors with disabilities in the culture and art complex would be needed.

Installation of pedestrian scramble is recently increasing due to pedestrian-oriented transportation policies issued in local governments. Pedestrian scramble is able to emphasize safety issues by reducing conflicts between pedestrians and vehicles when an exclusive pedestrian phase is employed. In spite of its positive property, pedestrian scramble has several negative points: an increase of a cycle length, a decrease of green time ratio, and an increase of total delay. This study delivers the impacts of pedestrian scrambles in terms of pedestrian convenience and traffic mobility. Authors analyzed the changes of traffic delays by comparing the installation and no installation of pedestrian scramble at an intersection by varying several variables: signal timings, traffic volumes, the number of lanes, and the number of pedestrian conflicts. The paper presents an analysis procedure as a guideline that assists practitioners in selection of appropriate intersections at where pedestrian scrambles are implemented.

Although importance of music education for the mentally retarded children is realized, it is hard to improve study effects for those children with the existing music education methods due to cognitive disorders of the children. In the paper, we propose a system to improve music cognition ability of the mentally retarded children. The system is designed based on the existing MMCP theory. Our system has the following characteristics. First, the system can improve cognitive, physical, social and emotional development as well as development of music cognition ability. Second, the individualized music education is possible for the children. Third, more active and interactive education is possible.

The recent study of the delay models have assumed random arrival which has a constant average flow rate throughout the cycle. However, where signals are spaced closely together or form part of progressive system, platoon flows are common and more closely represent reality. In such cases, those results are quite different pattern of estimated delay from that of observed one. In order to solve this problem, the 1985 HCM takes Progression Adjustment Factor (PAF) into account. In the 1985 HCM, however, it has deficiencies in defining and applying it, such as platoon ratio ($R_p$) and platoon arrival type. The Purpose of this study is to investigate theoretically the predictive ability of the individual models concerned through comparing the estimated delay and PAF suggested by NCHRP Report 339, KHCM or USHCM (1985) with the observed obtained by field survey at a signalized intersection.

This study was carried out to analyze the consumption expenditure condition of elderly persons with and without physical disabilities by social economic status and sociodemographic characteristics and to compare the results of those two groups for making an offer the basic materials to provide political support for elderly persons with physical disabilities. The statistical analysis of collected data was enforced through T-test, ANOVA and Crosstabs with SPSS 19.0 program. The results of this study are summarized as follows. First, the group with disabilities has presumed to be in relative poverty given that disposable income, academic career and total living expenses showed lower than the other group. Second, the component ratios of domestic foods and housing expenses of disabled group showed higher but those of specific spending items of expenditure such as social activities, reserving fund of social security for economic safety net, clothing and eating out expenses showed lower than the other group.

Roundabouts are actively installed to reduce unnecessary congestion and reduce traffic accidents. However, it is difficult to apply more than 450 cars per, hour. In addition, there is a downside to the concentration of delays in certain directions depending on traffic conditions. To compensate for these shortcomings, signal metering was introduced. Signal metering is a technique that gives red signals to adjacent left traffic flow in the event of a delay in a particular direction. The purpose of this study is comparing the effect of signal metering in conventional and special types (turbo roundabout, flower roundabout) of roundabout. VISSIM API is used for analysis. The analysis result show that only conventional roundabout signal metering algorithm reduce delay time per vehicle. As the result of the turbo roundabout and flower roundabout signal metering algorithm increase delay time per vehicle, signal metering algorithm can be applied in conventional roundabout.

This paper documents the development of a bi-objective(minimizing delays and Queue lengths) cycle-free signal timing length model using Genetic Algorithm. The model was embodied using MATLAB. the language of technical computing. A special feature of this model is its ability to concurrently manage delays and queue lengths of turning movement concurrently. The model produces a cycle-free signal timing(cycles and green times) for each intersection on the cycle basis. Appropriate offsets could be also accomplished by applying cycle-free based signal timings for respective intersections. The model was applied to an example network which consists of four intersections. The result shows that the model produces superior signal timings to the existing signal timing model in terms of managing delays and queue lengths of turning movements.

The conflict of opposing pedestrian traffic-flow in a subway station(made up of stair, passageway, and escalator) diminishes the convenience and mobility of its users. In addition, the station's efficiency would be negatively affected by the growth of delay and queue length in pedestrian facilities. As these phenomena have been resulted by the overlapping in pedestrian's traffic-line, the separation of it would alleviate these problems. For the criteria and methodology of separation, this paper has investigated the bi-directional queue length and delay on the entrance of each facility (stair, passageway and escalator). Since the pedestrian flow exists bidirectionally, we have used the weighted average by inflow rate for the delay value. For the optimization of the separation, the Genetic Algorithm has been utilized in order to minimize the delay.
