For handicapped person who have a handicap in moving, vehicles are indispensible, especially in the viewpoint of handicapped person's participation for social life by rehabilitation, the freedom of movement equaling to nonnal person is a important factor for improving the quality in being complete growth.In the purposese of positively social participation of handicapped person, this study investigated the general problems about using a means of transportation in the users of wheelchair and for solving these problems and approached, in the viewpoint of styling, vehicles were considered from character of self-supporting in getting on and off a car. For that first, this study was progressed by suggesting invigorating convenience facilities in already established vehicles for the user of a wheelchair and the part of moulding of modified vehicles in a structure. Moreover, making a selection of domestic vehicles arbitrarily, analyzing a internal structure of a boarding of a wheelchair, and suggesting the modified model of vehicles by the sketch.

The purpose of this study was to examine children's dramatic play and dramatic play themes in the same-age and mixed-age kindergarten classrooms. The subjects were 45 children in three classrooms of 4-year-olds, 69 children in three classrooms of 5-year-olds, and 60 children in three mixed-age classrooms of 4-and 5-year-olds. Observations were conducted by videotape recordings. Observation periods were of five-minutes duration. There were ten observations of children's indoor free-play periods. Four-and five-year-olds in mixed-age classrooms were more likely to engage in group-dramatic play than 4-and 5-year-olds in same-age classrooms. Four-year-olds in mixed-age classrooms were more likely to engage in domestic and family, war/violence, school, animal, and vehicle play themes than 4-year-olds in same-age classrooms. However, 5-year-olds in mixed-age classrooms were more likely to engage in family and school play themes than 5-year-olds in same-age classrooms. 5-year-olds in same-age classrooms were more likely to engage in vehicle and animal play themes than 5-year-olds in mixed-age classrooms. 5-year-olds in same-age classrooms did not differ from 5-year-olds in mixed-age classrooms on the war/violence themes used during dramatic play. In terms of sex differences, boys were more likely to engage in violence, adventure fantage themes than girls. Conversely girls were more likely to engage in family/marriage static play themes than boys.

Environmental noise at high intensities directly affects human health by causing hearing loss. Although scientific evidence currently is not conclusive, noise is suspected of causing or aggravating other diseases. Environmental noise indirectly affects human welfare by interfering with sleep, thought, and conversation. Noise emission from motorized vehicle includes power unit noise, tire/pavement noise and aerodynamic noise. Among them, tire/pavement noise is noise emission from interaction of the tire and road surface when the vehicle cruises over the surface of pavement. In general, portland cement concrete(PCC) pavement is known to create more noise than asphaltic surfaces though it has the advantage of durability and superior surface friction. However, the results of preliminary laboratory test showed exposed aggregate concrete(EAC) has and effect on reducing tire/pavement noise. Based on the laboratory test. pilot construction of exposed aggregate concrete pavement was completed and series of in-situ measurements were conducted for noise analysis including the pass-by noise measurement and the close-proximity method. Conclusively, it is expected that tire/pavement noise represent significant portion of noise levels at higher frequencies and it would be reduced on special textures of pavement such as exposed aggregate concrete.

While the advanced trffic environment systems are developed recently, the traffic systems for transportation vulnerable are still under development and their social life are limited as well. In order to the secure their mobility rights, it had been required to set up the particular system for the traffic welfare. One of the significant items is the express bus operation for wheelchair users. Thus, the research of development and operation for express buses with wheelchair users was funded by the Korean government. Before the express bus development for wheelchair users based on the current bus model, this study set up the evaluation method for the bus rollover characteristics to ensure occupant safety using the finite element method. The partial bus model was developed corresponding to the full bus model response under rollover event and the evaluation method based on two model (full bus model and partial bus model) responses is planned to apply the model development of express bus modification for wheelchair users.

Residents under hazard and disaster conditions should be evacuating to the pre-assigned nearest safety facilities, community hall, local schools, friend's houses, etc. in a safety zone, quickly as soon as possible. The small percentage of evacuees shows serious economy class syndrome after the quake, because those people are forced to a stressful dairy evacuee-life in scattered homes and/or in-vehicle, for instance. Then, we consider on supporting evacuees using heart rate variability, Geospatial Positioning System (GPS) and WiFi functions of a smartphone, and Web-server on the Internet to keep their health in good conditions.

In this study, we categorized the subjective recognition of 20's young generation about virtual currency into a few meaningful types and analyzed the characteristics of each type using the Qmethodology. For the Qpopulation, we selected a total of 337 samples which were derived from the Internet search, in-depth interviews, and literature survey, chose the final 51 Qstatements, and performed the Q-classification for the 40 P samples of 20's, including university students. Then, we analyzed the results using the PC-QUANL program. From the analysis, we found meaningful differences between each recognition type, and, after classifying the recognition types into four, we named each of them as 'investment-vehicle' type, 'future-technology' type, 'kind of gambling-like plays' type, and 'foamy faddishness' type. We hope that this research result can contribute to follow-up research and social discussion as base materials.

The purpose of this study was to investigate what life safety services the elderly living alone in rural areas need and to propose the life safety services that they actually need. The research subjects were 1,000 people aged 65 years and over living in the rural areas of Korea. Among the total 1,000 respondents, 283 elderly people who did not live together with their married children were included in this study. Data were analyzed through frequency analysis, descriptive statistics, and multiple regression analysis. The results of this study were as follows. First, the needs of health care services and vehicle support services (when the elderly went to the hospital or walked out) were high. These were services related to health, which means that the health of the elderly is not good and that they are interested in health. Of course, it is important to treat the disease. However, it is more important to prevent disease and maintain health. An expansion of these services is urgently needed. Second, the need for life safety services was affected by the frequency of contact with neighbors, uncomfortable housing, exercise, the frequency of contact with children, gas accidents, and nutrition variables. Through this analysis, we propose to include the housing improvement service, nutrition improvement services, and expanding social relations services in the life safety services.

As the Seoul metropolitan city has the largest numbers of population and vehicles, the citizens can be exposed to hazardous air pollutants(HAPs) mainly from the vehicular exhaust and human activities. In this study, we proposed a systematic method for the selection of priority monitoring areas for HAPs using Geographic Information System (GIS). First, emission parameters(emission data, vehicle registration, monitoring data, and so on) and population parameters (population and population density) were plotted using the inverse distance weighted (IDW) interpolation. Then, the interpolation data for individual parameters, which were normalized between 1 and 5 points, were compiled for 270 grids with a resolution of $2km{\times}2km$. The total score of each grid was calculated using weights(1~5) for the individual parameters. The final ranking of each grid was assigned by four scenarios with varying fractions of the emission and population parameters from 50 : 50 to 80 : 20. Consequently, nine grids were suggested as priority monitoring areas, and all of them are located in the southwestern part of Seoul.

Background: The poultry industry suffers losses from problems as pale, soft and exudative (PSE), and dark, firm and dry (DFD) meat can develop in meat as a result of short- and long-term stress, respectively. These abnormalities are impacted by pre-slaughter animal welfare. Methods: This work evaluated the effects of open vehicle container microclimate, throughout the $38{\pm}10km$ journey from the farm to the slaughterhouse, on commercially turkey transported during the Brazilian winter season. The journey was initiated immediately after water bath in truck fitted with portable Kestrel anemometers to measure air ventilation, relative humidity, temperature and ventilation. Results: The inferior compartments of the middle and rear truck regions showed highest temperature and relative humidity, and lower air ventilation. In addition, the superior compartments of the front truck regions presented lower temperature and wind chill, and highest air ventilation. The breast meat samples from animals located at the inferior compartments of the middle and rear truck regions and subjected to with water bath (WiB) treatment presented highest DFD-like and had lowest PSE-like meat incidence than those from animals located at other compartments within the container. Lower incidence of PSE-like meat was observed in birds without water bath (WoB). Conclusions: Assessment on turkeys transported under Brazilian southern winter conditions revealed that breast meat quality can be affected by relative humidity, air ventilation, temperature, and transport under subtropical conditions promoting color abnormalities and the formation of simultaneously PSE-like and DFD-like meat.
