  • This study investigated the general characteristics of mobility disadvantaged persons with disabilities, and to suggest implications to ensure personal mobility with the greatest possible independence for the physically disabled in community. The survey questionnaire included the categories as follows: the general characteristics of the participants, the status of outing and mobility, usage of low-floor buses & taxi for the disabled, service improvement, and mobile support center. Data collected from 219 with physical disabilities were analyzed for this purpose by using descriptive statistics. The study results showed that 54.6% of the total tended to go out everyday, and 17.0% rarely. 53.4% could go out without any assistance, and the major obstacles not to go out were stairs and inconvenience of public transportation. 26.9% used low-floor buses, and 71.1% preferred to use taxi for the disabled. The average waiting time for the usage of low-flow buses and taxi was 66.57 minute and 42.65 minute, separately. 78.7% insisted that the function of mobile support center in the community should be expanded, whereas only 49.8% recognized the role of mobile support center. Based on the study results, the researchers suggested to facilitate access by persons with disabilities to mobility aids, and to improve the actual state of pedestrian environment. In addition, the function of mobile support center should be expanded to help the mobility disadvantaged persons live independently in community, thereby contributing to the promotion of their quality of life.

  • Objective: The purpose of this study was to develop and evaluate smart secondary controls using iPad for the drivers with physical disabilities in the driving simulator. Background: The physically disabled drivers face problems in the operation of secondary control devices that accept a control input from a driver for the purpose of operating the subsystems of a motor vehicle. Many of conventional secondary controls consist of small knobs or switches that physically disabled drivers have difficulties in grasping, pulling or twisting. Therefore, their use while driving might increase distraction and workload because of longer operation time. Method: We examined the operation time of conventional and smart secondary controls, such as hazard warning, turn signal, window, windshield wiper, headlights, automatic transmission and horn. The hardware of smart secondary control system was composed of iPad, wireless router, digital input/output module and relay switch. We used the STISim Drive3 software for driving test, customized Labview and Xcode programs for interface control of smart secondary system. Nine subjects were involved in the study for measuring operation time of secondary controls. Results: When the driver was in the stationary condition, the average operation time of smart secondary devices decreased 32.5% in the normal subjects (p <0.01), 47.4% in the subjects with left hemiplegic disabilities (p <0.01) and 38.8% in the subjects with right hemiplegic disabilities (p <0.01) compared with conventional secondary devices. When the driver was driving for the test in the simulator, the average operation time of smart secondary devices decreased 36.1% in the normal subjects (p <0.01), 41.7% in the subjects with left hemiplegic disabilities (p <0.01) and 34.1% in the subjects with right hemiplegic disabilities (p <0.01) compared with conventional secondary devices. Conclusion: The smart secondary devices using iPad for people with hemiplegic disabilities showed significant reduction of operation time compared with conventional secondary controls. Application: This study can be used to design secondary controls for adaptive vehicles and to improve the quality of life of the people with disabilities.

  • The research hypothesis of this paper is that education for smart device utilization has a positive effect on ability and utilization of smart devices for the disabled. The data for disabled of NIA's 2012 survey about digital divide is used, and the research method is "Heckman's 2-stage method" which considers the problem of selection bias. As a research result, this paper says that the disabled who had experience of education for smart device utilization have higher level of ability and utilization of smart devices. Also, a high level of education and family income, professional career and young generation have been very positive effect on the high level of ability and utilization of the disabled. The level of ability and utilization of the blind tend to be lower than those of the physically disabled. These results remind that the education for smart device utilization for the disabled is important and effective. And various contents and methods of education which are appropriate for the disability types should be developed.

  • The spectrum of physically challenged patients who visit to a dental clinic for treatments are diverse: from ones of mild disabilities, who lead their lives in a similar way of ordinary people, to others who suffer from diseases that are difficult to be diagnosed, and need medical expertise due to systemic care or special techniques and instruments because of behavior management and difficulty of treatments. The patient in this case was 25-year-old autistic male patient who visited the clinic on account of overall treatment for multiple carious lesions. He could perform normal daily life to some degree under the care of a guardian. This case report describes predicaments of making a treatment plan resulted from lack of information about disabled patients, and difficulties of proceeding treatment procedures under general anesthesia. It is considered that sufficient consultation and history taking are needed before treatment for disabled patients.

The subjects in this study were 198 domestic disabled people in Jeollabuk-do, on whom a survey was conducted from May 1 to June 1, 2008. After the collected data were analyzed with SPSS WIN 12.0 program, the following findings were acquired: 1. 68.2% of the subjects had an experience of using dental service institutes. Over 80.0% of the physically disabled, the mentally handicapped, and the sensory-disturbance sufferers each used dental service institutes in their locations. Regarding the reason for visiting dental service institutes, 43.4% of the physically disabled visited for regular examination (the largest group for that reason), followed by the mentally handicapped with 37.9%. 43.5% of the sensory-disturbance sufferers visited for pain and fracture. 2. The subjects' life quality level relating to oral health was found to be an average 3.39 point score. There was a statistically significant difference in their life quality levels in terms of demographic features, such as age, religion, marriage/non-marriage, education, and subjective health status variables. Those experienced in using dental service institutes enjoyed higher levels of life quality (p=.011). And, with regard to disability characteristics, the degree of disability and the period of disability influenced the quality of life with a statistical significance. 3. Regarding variables influencing the life quality of subjects, in terms of general characteristic variables, subjective health status were influential variables, and in terms of characteristic variables relating to the use of dental clinics and disability, the experience of using dental service institutes influenced the quality of life. In conclusion, nationwide efforts to nurture separate dental personnels responsible for the disabled, to expand relevant facilities and to improve the health care insurance are required to promote the oral health of domestic disabled people's.

  • To investigate determinants of health care utilization of the physically disabled over 20 years old in age living in Taegu city, a self-administered questionnaire survey was carried out for 337 disabled persons with chronic illness from April to July, 1997. Health care utilization .ate was 81.9%(69.1% for hospital or clinic and 12.8% for pharmacy). Marital status, job, health concern, and response to illness showed statistically significant relationship with health care utilization(p<0.05). By path analysis, job, economic status, medical security type and response to illness had a significant direct effect on health care utilization(p<0.05), however, health concern and regular source of care had an indirect effect. The reasons of no health utilization were due to economic problem(31.1%), no symptom(18.0%), inconvenience to seek care or no accompanying persons to be helped(14.8%), unseriousness of the severity of the illness(14.8%), too busy to be treated or no free time(8.2%), hopeless prognosis to be treated(6.6%) in order. In conclusion, it is recommended that the program for expanding medicaid, improving socioeconomic status by getting a job and health education to increase the health concern toward physically disabled should be implemented to increase health care utilization rate.
