The purpose of this study is to examine the degree of community integration of visually impaired people who have the limitation of mobility in comparison with another disabled and to find factors affecting community integration. The data were obtained through telephone interview with visually impaired people. The final sample was consisted of 1,004 respondents. The data were analyzed using statistical techniques such as crosstabulation, t-test, and hierarchical regression. In this study, the factors affecting community integration was divided into four dimensions : the attribution to disability, physical functioning, psychology and social support system. The major findings of this study were as follows: First, the factors affecting community integration of visually impaired people were age, education, economic status, social support, information support and participation of rehabilitation service. Second, the factors affecting community integration of the low vision and the blind are the limitation of daily activities and social support. But the factors affecting community integration of the blind are participation of education for braille and that of the low vision are information support and participation of rehabilitation service. Finally, the person losing eyesight since school age were the more limitation of daily activities than the person losing eyesight in babyhood. The factors affect community integration of the former are social support, information support, participation of education for braille, and rehabilitation service. The current findings suggest that intervention and policy aimed at improving social support system and formal services such as education, rehabilitation services should be considered by rehabilitation professionals and policy makers.

In this paper, we propose the method for automatically transfers images into tactile maps information based on cognition characteristics of visually impaired persons to more easily provide various image information for visually impaired persons. The proposed method automatically classify color images into row complexity and high complexity based on intensity information and transfer images into tactile map information using each different transformation process. Experimental evaluation, We performed with visually impaired five persons experiments for evaluating the recognition and satisfaction that tactile maps of the proposed automatic transforming method and the manually generated tactile maps of braille textbooks. Experimental results, the recognition and satisfaction that the tactile maps of the proposed method generated are very similar to those of the tactile maps of braille textbooks. Therefore, it could hugely be reduced the time and money of production education materials, and it could greatly improved educative results because it can add more easily that many image data of education materials.

In the knowledge and information society, there is an increasing importance of information, being unable to access this information becomes a huge disadvantage. Blind and visually impaired users who are using assistant equipment such as screen readers are the very class that is having trouble accessing the web content that public libraries provide. In this research 10% of each region's libraries were picked as a research sample. Most of the web content that the public libraries provided did not meet the Internet web content accessibility guidelines as a Korean standard. Also evaluation into web accessibility by the visually impaired was also low. This research suggests some solutions for libraries to reduce the disadvantages that are put upon visually impaired people from various views such as perceivable, operable, understandable, and robust.

This study investigated how people who became blind midway through life used music and how these uses differed according to individual factors. Sixty-one late-blind adults aged 40 to 60 years attending six welfare centers for the blind in Seoul and Gyeonggi region participated in this research. Participants were asked to complete a 25-question survey in Braille on music utilization and preference, as well as the purpose of music utilization. The response rate was 87.1%. The results were as follows. First, with regard to listening preference, they reported preferring to listen to upbeat popular music on the radio when resting at home. They liked to sing along to lyrics reminiscent of personal memories. String instruments were preferred when playing an instrument. With regard to the reason for using music, inducing mood change was found to be the biggest reason, followed by seeking enjoyment, comfort, sense of achievement, and sense of belonging. Third, for people with adventitious visual impairments, individual factors, such as gender, level of disability, and period without eyesight, did not reveal any significant differences. Last, participants were found to obtain a higher sense of belonging through music compared to those having low vision. Regarding time without eyesight, it appeared that the shorter the period, the higher the sense of belonging participants had from utilizing music, and vice versa. This study provides fundamental information for organizing an effective music program that can meet the needs and demands of people with adventitious visual impairments.
