In this study, through a survey on traffic safety campaigns for electric wheelchairs for the disabled, we found out what is necessary to solve the inconvenience of disabled people driving electric wheelchairs and living in society. The conclusions for each role of the severely disabled are as follows. The government has enacted a law on fostering convenience facilities for the disabled in accordance with reality so that the disabled, who are vulnerable to transportation, do not have any inconvenience in their social lives. However, it is not kept in reality, so there are many obstacles to the social activities of the disabled. In addition, local governments should subscribe to electric wheelchair insurance for the disabled to minimize the damage to the disabled in the event of an electric wheelchair accident. Organizations related to the disabled provide safety wheelchair driving education to prevent electric wheelchair accidents in advance and receive complaints about inconvenience. It can be concluded that people with severe disabilities can prevent accidents in advance by installing a moving ring tone on an electric wheelchair so that they can know the movement of the surrounding wheelchair.

Purpose: This study aimed to determine health problems experienced by workers in special employment relationships (WSER) and identify coping strategies used when such problems occur. Methods: This qualitative study used the focus group interview method. Thirteen study participants included five home-visit tutors, five insurance salespersons, and three credit card recruiters. The interviews were conducted from November 2018 through January 2019, with each occupational group interview lasting about 2 hours. Analysis based on phenomenological research was independently performed by two researchers. Results: Most participants had common health problems involving vocal cord symptoms, and stress related to emotional labor and traffic accidents. The unique health problems included cystitis, musculoskeletal, and digestive symptoms in home-visit tutors; reduced vision and hearing in insurance salespersons; and mental distress in credit card recruiters. There was no protection system for their health coverage, and the company emphasized their self-employed status to avoid taking responsibility for them. Twelve participants did not purchase occupational accident insurance owing to both not having adequate information and economic burden concerning premium status. Conclusion: WSER experienced both physical and mental health problems. These problems were caused by their unstable employment status, and the social security system for their coverage being non-functioning.

This research is the study on the comparative evaluation of SPC (Staggered Pedestrian Crossings) vs PC (Pedestrian Crossings) using risk analysis. Accident factor was elicited by survey of driver's and pedestrian's at SPC & PC. I estimated the weight of a risk of violation and a mental burden by AHP (Analytic Hierarchy Process) and compared degree of risk at SPC AND PC. In conclusion, a new alternative plan of a pedestrian crossing system, staggered pedestrian crossing which plays an important role in traffic flow, pedestrian's crossings which plats an important role in traffic flow, pedestrian's convenience and traffic safer is sager than pedestrian crossings the degree of risk used this study doesn't imply an measure of the number of accident and the rate of accident, in estimating the degree of risk of pedestrian crossings, we should analyze more data of accident, behaviors, and road circumstance to include driver's and pedestrian's violation behavior in an estimate index.

Background: The incidence and etiology of facial bone fracture differ widely according to time and geographic setting. Because of this, prevention and management of facial bone fracture requires ongoing research. This study examines the relationship between socioeconomic status and the incidence of facial bone fractures in patients who had been admitted for facial bone fractures. Methods: A retrospective study was performed for all patients admitted for facial bone fracture at the National Medical Center (Seoul, Korea) from 2010 to 2014. We sought correlations amongst age, gender, fracture type, injury mechanism, alcohol consumption, and type of medical insurance. Results: Out of the 303 patients meeting inclusion criteria, 214 (70.6%) patients were enrolled in National Health Insurance (NHI), 46 (15.2%) patients had Medical Aid, and 43 (14.2%) patients were homeless. The main causes of facial bone fractures were accidental trauma (51.4%), physical altercation (23.1%), and traffic accident (14.2%). On Pearson's chi-square test, alcohol consumption was correlated significantly with accidental trauma (p<0.05). And, the ratio of alcohol consumption leading to facial bone fractures differed significantly in the homeless group compared to the NHI group and the Medical Aid group (p<0.05). Conclusion: We found a significant inverse correlation between economic status and the incidence of facial bone fractures caused by alcohol consumption. Our findings indicate that more elaborate guidelines and prevention programs are needed for socioeconomically marginalized populations.

This study intended to find out how the handicapped use medical aid, their satisfaction at using it and so on. First a preliminary survey(Apr. 20$\sim$24, 2002) was made for the handicapped who had been cured for rehabilitation by wearing medical aid at hospitals and welfare center in Jeonbuk region. Then total 120 subjects were asked to fill out a standardized questionnaire from May 15$\sim$22, 2002. Out of total 95 questionnaires collected, 84 questionnaires were analyzed except for 11 cases unsuitable for the intention of this study. The results can be outlined as follows: 1. In general characteristic, it was found that the causes of disability included disease(35 respondents; 41.7%), traffic accident(23 respondents, 27.4%) and so on. In addition, 1st handicap comprised the majority(32 respondents; 58.2%) in handicap grade and ankle foot orthosis(or b-k orthosis) was most often used as medical aid(28 respondents: 33.3%) 2. In particular, it was also shown that the 1st handicap mainly resulted from traffic accident(15 respondents, 27.3%) and post-disease disability (11 respondents, 20.0%). They wore medical aid for 1 year or less on the average, because they were hospitalized for cure, which showed statistically significant level(P<0.05). 3. It was found that total 69 respondents(82.1%) were more or less satisfied with their medical aids depending on the causes of disability, and total 46 respondents(83.6%) were satisfied with their aids according to their handicap grade, but there were no statistical significance. 4. Total 56(66.7%) respondents answered that they would purchase medical aid on their own expenses, when they became handicapped. And the price of medical aid ranged from $\300,000{\sim}400,000$(25 respondents: 29.8%) to \ 500,000 or more(24 respondents: 28.6%). It means that they purchased more or less expensive medical aid on their own expenses, which showed statistical significance(P<0.05). 5. If there was any failure of medical aid, 9 respondents(37.5%) answered that they would be serviced from medical companies, and 7 respondents(29.2%) would be serviced from medical aid manufacturers. Most respondents were serviced for their medical aids from related companies. For the question about the causes of dissatisfaction upon repair service, 11 respondents(45.8%) answered that existing service company provided unskilled repair services and other respondents answered that there was no spare part or higher service expenses than they thought. These answers had the statistical significance(P<0.05). However, 20 respondents(79.2%) answered that they were satisfied with the repair service, which means that most respondents are satisfied with the service. In view of the results as described above, it can be concluded that their handicap or disability results from disease or sequelae after traffic accident and most of the affected wear their own medical aid. In the future, it is required that the medical insurance should cover those medical aids, and the service for failed medical aids should be commissioned by technical serviceman to realize customized manufacture and repair service according to different causes so that the handicapped can enjoy more or less comfort and convenience in their daily lives without any extreme difficulty.

Motor vehicle crashes are the leading cause (70%) of children injury and fatality. 98% of Children under the age of 9 who came to emergency room with a traffic accident are not seated in CRS. Reduction in mortality when using CRS (NHTSA study), 71% for infants of 1-2 years old, 54% for 3-6 years old and 7-12 years old. It is very important and essential to use CRS for child passenger safety. But in Korean market, the CRS fitment rate is relatively low (20~40%). For European market, at the start of 2013, Euro NCAP started to check how easy it is to install the most common seats. And US market, NHTSA is planning a new consumer information program of CRS fitment for near future. This study examines CRS installation performance of 3 vehicles which are produced by GM Korea and 21 CRS which are based on sales volume in Korean market. Purpose of this study is to identify both vehicle and CRS design that causes bad interaction for CRS installation.

A traffic accident which happens in Expressway during dense fog is more likely to cause the sequential accidents and high death rate. So, the preventive measures shall be taken at dangerous areas to enhance the efficiency of roads and minimize the accidents and the resultant damages. So, it is necessary to find out the characteristics of freeway zone which has high risk of fog occurrence and to establish the comprehensive safety strategy on installation and operation of the safety equipment. In this study, I developed a fog forecasting model by using the freeway fog data. This model can be used as the fog forecasting model in dealing with fog problems when new road is planned. The model was developed by using a statistical analysis technique or the regression analysis, focusing on the variables such as geographical features and regional conditions, distances to water sources and the area of water source. I have segmented the models by classifying the area into inland area and coastal area. The distance to water source and area of the water source located around the freeway were found to be main factors causing fog.

On roads vehicles are the bossy, while pedestrians are the frangible. The current paper has a purpose for contributing to pedestrian's safety. First, it studies the association between demographic parameters and TPB(Theory of Planned Behavior)'s variables(pedestrian's attitude toward crossing behavior in roads, personal norm, etc.) and his/her crossing intention, perceived risk while crossing, and the experience of past traffic accidents. Its sample comes from a specific population(college students). Further, the present study endeavors to explain the portion of human cognitive failure/error, impulsiveness, time perspective, and probabilistic/math-logical judgment ability in pedestrian's riky crossings on roads. Research results found that TPB variables and such a few human characteristics have some significant association with the risky crossing intention on the road. Considering the human psychological portion in pedestrian accidents would help us prevent the accidents and reduce unhappiness of the accidents and, further, economic loss and insurance expenditure related with the accidents.
