The National Institute of Special Education developed and distributed software textbooks for disabled students according to the necessity of practical course in elementary school and information in middle school in the 2015 revised curriculum. It is a textbook provided from the perspective of education opportunity equity but the content of programming education for visually impaired students was insufficient. Therefore this study was conducted for the purpose of confirming the effectiveness of programming education for visual impaired students and providing the direction of future programming education. In order to achieve the purpose, programming classes were conducted for blind students in the 6th grade of elementary school. As a result of a study using "Blocks4All", a block-based programming tool with robots, students participated in classes actively and efficacy, intrest, and usefulness of programming are high. This study is meaningful in that it confirmed the possibility of programming education for visually impaired students.

This study was conducted to improve the education method for improving perception awareness of the visually-impaired. 'Hear me later' was designed and implemented based on VR content that allows the visually-impaired experience in the eyes and environment. The main target is from middle and high school students to adolescents in their twenties. It is consisted of a student, the user's daily life with waking up at home in the morning, going to school, taking classes at school, and disembarking home late in the dark. In addition, 10 quests are placed on each map to induce users' participation and activity. These quests are a daily activity for non-disabled people, but it is an activity to experience uncomfortable activity for visually impaired people. In order to verify the effect of 'Hear me later', 8 participants in their early teens to early 20s' perception of visually impaired people was measured through pre and post evaluation of VR contents experience. In order to verify the effect of'Hear me later', 8 participants in their early teens to early 20s' perception of visually impaired people was measured through pre-post evaluation of VR experiences. As a result, it was found that in the post-evaluation of VR contents experience, the perception of the visually impaired was increased by 30% compared to the pre-evaluation. In particular, misunderstandings and changes in prejudice toward the visually impaired were remarkable. Through this study, the possibility of a VR-based disability experience education program that can freely construct space-time and maximize the experience was verified. In addition, it laid the foundation to expand it to various fields of improvement of the disabled.

In this study, the characteristics of visually impaired elementary students' conceptions on dissolution were investigated. The semi-structured interviews about phenomenon of dissolution, uniformity of solution, conservation of mass on dissolving and volume change during dissolving were conducted with 4 fifth-grade elementary students with visual impairments (three were blind, and one had low-vision). Interviews were recorded and the data were analyzed after transcription. As a result, students with visual impairments knew well about the phenomenon of dissolution, uniformity of solution, and conservation of mass on dissolving, while they couldn't explain volume change during dissolving. Although students with visual impairments were found to have similar level of understanding with students without visual impairments, they had sounder understanding about uniformity of solution. However, students with visual impairments had superficial understanding based on phenomenal experiences. Some of students with visual impairments tried to give micro-level explanation. Based on these results, educational implications were discussed.

Assistive technologies are necessary for ensuring independent living and equal participation in an information-based society for people living with disabilities (PLWD). This study investigated the assistive technology preference of students with visual disabilities, and the approach academic libraries should adopt in procuring assistive technologies. The study adopted a quantitative research method, with a survey as the research design. The study was conducted among visually disabled students in four public universities in Nigeria. Using the total enumeration method, an online questionnaire was used to obtain information from 151 students who voluntarily agreed to partake in the survey. The study found that access to electronic resources, scanning/conversion of print resources to electronic formats and access to information on the Web were among the technology-based services provided to visually disabled students. COBRA, ZoomText, Supernova and Dragon Naturally Speaking are the most preferred assistive technologies (software). At the same time, handheld scanners ($\bar{x}=4.40$) and braille keyboards ($\bar{x}=4.60$) are the most preferred assistive technologies in the hardware category by visually challenged students. The study further revealed that the library management should consult with students living with a visual disability before procuring assistive technology. Findings from this study thus provide further evidence of the need for librarians to fulfil their moral and legal obligation in advocating the provision of assistive technologies. Library administrators and university stakeholders should expedite actions on meeting the assistive technology needs of people living with visual disabilities. These actions should transcend mere policy formulation on the provision of assistive technologies to restructuring their services and spaces to accommodate assistive technologies as information service delivery tools for people with visual disabilities.

Blindness or visually handicaps are found to be an important factor destroying lifestyles as well as a physical problem. According to the data of handicapped person's(v.h.p) registered in Korea, the number of v.h.p. has not decreased. Especially, visual handicapped adolescents (v.h.a.) suffer from an insufficiency of social support under the current education system. There is a special education system for v.h.a. in Korea, and, as a result v.h.a.'s are educated separately from general students and communites. Compared with the self-conception of general students, v.h.a.'s have a more negative self-conception. Among former studies 51.7% of v.h.p's are not in good health. This, of course, means that their handicap impacts on other health problems. The first purpose of this study is to find out the causes of disease and the degree of social support, self-esteem, health management behavior provided and then to analyze the effect of self-esteem and social support on their behavior. To accomplish these purposes, visually handicapped the middle and high school students in Seoul city and Kyung-gi province were selected and 300 students sampled. The main results are as follows : 1) The highest specific handicap is impaired lenses (19.7%). 2. There were high correlations between health management behavior, self-esteem, and social support. 3. Social support is a more important variable than self-esteem on health management behavior. 4. Age of entry and length of stay in their special dormitories, and teacher's support account for 16% of psychological health management behavior 5. Age of entry in their special dormitory and total degree of social support account for 12% of preventive health behavior.

In this study, visually impaired secondary students' conception of "changes of state of water" was explored. Science inquiry activity for students with visual impairments was implemented to 16 middle school students and 15 high school students from school for the blind. 14 of them were totally blind, 13 had low vision and the others were not identified. Inquiry activities were conducted by communicating with the researcher while students were individually exploring the molecular models of water and ice developed for the study. After the exploration, students were asked to explain the concept of changes of state of water with the model they explored. Opinion on the need and the usability of this kind of tactile model was also asked to them. All conversations were recorded, transcribed, and analyzed. As a result, students with visual impairments answered exactly about the materials used for the model and their numbers. However, they didn't know what the model stood for. They had experiences of learning molecule of water and changes of state of water, but it was a phenomenon and superficial understanding. Students got to understand the molecular structures of water and ice, and had a positive perception on the need and the usability of the model. Based on these results, educational implications were discussed.

The subjects of this study are three visually-impaired undergraduates currently considering if they should take a leave of absence after finishing the first year in S University located in Busan City. From March to July, 2018, this researcher explored the meaning of their university entrance and the essential meaning and structure of their school life experiences by using Giorgi's phenomenological methodology. According to the results, this author drew 32 meaningful statements and also 10 main themes, "the excitement of campus life and the name of being an undergraduate", "parents' suggestion", "something other than being a massager", "Is it a place that anyone can enter? Or, is it a special place?", "loneliness within the public", "Everything is an obstacle.", "It's not giving up, but still I am in a vague moment.", "the beginning of another conflict", and "studying in a university is not for the present but for the future". They were categorized into being a university student and the meaning of it (category1), adaptation to university life and reality (category 2), and one year after the entrance: the meaning of being a university student (category 3). Based on the above results, this author intends to provide foundational material about what universities can do for visually-impaired students to adapt to university life in the initial steps properly.

The study goals are establishing a library management plan for the school for the blind in Korea and also developing a structured library program, which reflected the patron's perception. We surveyed the students in three schools for the blind to identify their perception and usage statistics of the libraries. The analysis of the survey led to a school library program framework consisting of four types. To verify the applicability and effectiveness of the framework, we designed ten programs to meet the needs of the schools by consulting respective school's teachers. We administered the second survey after the classes, and we found that there were positive increases in the frequency of library use, a number of books read, perception about the libraries, amount of information used, and self-directed learning willingness.

Objective: The aim of this study is to predict human visual target search using ACT-R cognitive architecture in real scene images. Background: Human uses both the method of bottom-up and top-down process at the same time using characteristics of image itself and knowledge about images. Modeling of human visual search also needs to include both processes. Method: In this study, visual target object search performance in real scene images was analyzed comparing experimental data and result of ACT-R model. 10 students participated in this experiment and the model was simulated ten times. This experiment was conducted in two conditions, indoor images and outdoor images. The ACT-R model considering the first saccade region through calculating the saliency map and spatial layout was established. Proposed model in this study used the guide of visual search and adopted visual search strategies according to the guide. Results: In the analysis results, no significant difference on performance time between model prediction and empirical data was found. Conclusion: The proposed ACT-R model is able to predict the human visual search process in real scene images using salience map and spatial layout. Application: This study is useful in conducting model-based evaluation in visual search, particularly in real images. Also, this study is able to adopt in diverse image processing program such as helper of the visually impaired.
