언어 및 신체장애가 있는 사람들은 의사소통을 하는데 많은 시간이 소요되거나 불가능한 경우도 있으므로 컴퓨터를 이용한 보완 대체 의사소통시스템은 장애인들의 의사소통을 도와주는 중요한 도구이다. 그러나 신체장애를 가진 사람들은 키보드, 마우스 등의 입력장치를 원활하게 사용하지 못하므로 단순한 입력만으로 시스템을 사용하여 의사소통을 할 수 있어야 한다. 따라서 본 논문에서는 간단한 입력만으로 의사소통을 할 수 있는 의사소통지원시스템을 설계하고 구현하였다. 장애인들이 많이 사용하는 빈출문장들을 수집하여 9개 생활언어 그룹으로 분류하여 제시하므로, 몇 번의 선택 동작만을 이용하여 자신이 원하는 문장을 찾을 수 있도록 하였다. 원하는 문장이 없는 경우에는 천지인 자판을 제공하므로 문장을 만들 수 있고, 만들어진 문장을 빈출문장 그룹에 포함시켜서 다음번에 사용할 수 있도록 하였다. 또한 각 그룹에 속한 문장들은 사용자의 사용 빈도에 따라 순위를 바꾸어 줌으로써 가능한 입력 횟수를 감소시킬 수 있도록 개발하였다.

Purpose: The purpose of this study was to investigate the experience of falls and identify risk factors associated with falls. Methods: The participants were 233 community-dwelling elderly people in two cities. Data were collected by interviewing the elderly with structured questionnaires from May to June, 2012. For data analysis, descriptive statistics and multiple logistic regression were performed using SPSS version 17.0. Results: Age, educational level, living arrangement, health status, the use of assistive devices, the number of medication, hypertension, arthralgia, dizziness, fall efficacy, fear of falling, activity of daily living, and quality of life were significant associated with fall experience. Through multiple logistic regression analysis, arthralgia, dizziness, fall efficacy, and fear of falling were identified as significant predictors of falls. Conclusion: It is important to identify the risk factors for falls among the elderly living in community. Fall prevention interventions should be multifactorial, especially for the elderly who were identified as the high risk group.

Objectives : This study confirmed the limitation of long-term care insurance by analyzing media contents. Methods : Articles and reviews were searched with the article searching system (KINDS) from July 2008 to December, 2015. Results : Among the 155 articles examined, 61.1% highlighted the faults of suppliers, and 25.2% indicated the responsibility of the insurer. As for their purpose, 56.8% reported on accidents, and 32.3% provided information. Furthermore, 74.2% reported on negative contents and only 25.8% on neutral contents. The negative contents consisted of requesting false insurance benefits, amending the range and price indicating the very low salaries of the care givers, limitations on the care grade assessment, and problems related with assistive devices. The majority of neutral articles is for providing information. Conclusions : There were many problems starting from the early stage of the insurance. We must pay attention to these problems. Moreover, we should try to handle and prevent these problems with supportive responses from authorities.

Some things come easily to humans, one of them is the ability to navigate around. This capability of navigation suffers significantly in case of partial or complete blindness, restricting life activity. Advances in the technological landscape have given way to new solutions aiding navigation for the visually impaired. In this paper, we analyze the existing works and identify the challenges of path selection, context awareness, obstacle detection/identification and integration of visual and nonvisual information associated with real-time assisted mobility. In the process, we explore machine learning approaches for robotic path planning, multi constrained optimal path computation and sensor based wearable assistive devices for the visually impaired. It is observed that the solution to problem is complex and computationally intensive and significant effort is required towards the development of richer and comfortable paths for safe and smooth navigation of visually impaired people. We cannot overlook to explore more effective strategies of acquiring surrounding information towards autonomous mobility.

Voice is the most common means for communication, but some people have difficulties in generating voice due to their congenital or acquired disorders. Individuals with speech disorders might lose their speaking ability due to hearing impairment, encephalopathy or cerebral palsy accompanied by motor skill impairments, or autism caused by mental problems. However, they have needs for communication, so some of them use various types of AAC (Augmentative & Alternative Communication) devices in order to meet their communication needs. In this paper, a mobile application for literate people having speech disorder was designed and implemented by developing accurate and fast sentence-completion functions for efficient user interaction. From a user study and the previous study on Korean text-based communication for adults having difficulty in speech communication, we identified functionality and usability requirements. Specifically, the user interface with scanning features was designed by considering the users' motor skills in using the touch-screen of a mobile device. Finally, we conducted the usability test for the application. The results of the usability test show that the application is easy to learn and efficient to use in communication with people with speech disorders.

A bathroom in house has been stressed not only as a space for physiology and hygiene but also leisure and healthcare. However, the bathroom is the most likely space where an elderly person can have an accident and it is uncomfortable space for them because of their deteriorating physical ability. So the purpose of this study is to help the elderly use their bathroom conveniently by providing smart service. Therefore, we carry out 18 smart service patterns that contain assistive devices and sensors for bathroom. Considering applicability and frequency, from among these service patterns, we suggest 4 service patterns. First is a fall prevention service. This service helps elderly use the bathroom safely at night. Second is a getting ready to go out service. This service helps the situation that elderly use the bathroom after getting up in the morning. Third is a security service in daily life especially before or after meals. And final is a service regarding personal hygiene service after returning home. This service helps to shower or bathe after return home. These services have positive influence in medical expense reductions, good health care and self-reliance of elderly.
