The purpose of this study was to compare AAC service delivery system between Korea and U.S.A for appling effective 'AAC service delivery system. This delivery system complement the missing part in system of the current method and narrow blind area for system. The result of this research, increase suppling item of assistive communication device in public benefit and provide delivery system through construct infrastructure by assistive technology center, special education support center, developmental disorder support center, speech therapy center in each local area. Furthermore, assistive technology-related institute and academy develope training programs for human resources to delivery AAC service.

A range of problems rave risen as the results of the obligated charter service. Constant lack of operation improvement compared to regular routes and lower quality service are results of business practice by the service providers. lherefore, this study executed an actual research using AHP to present a method for improvement by investigating remote island clnrter service providers. Result shows tint the desirable method is to implement operation evaluation system to induce service providers to consistently put efforts on the operating system development.

최근 DSMS의 연구가 활발히 진행되고 있고, 그에 따른 고가용성 서비스를 제공하기 위한 환경으로 확장되고 있다. DSMS와 같은 실시간 데이터베이스 응용 시스템 분야나 임무 결정적인 응용 시스템을 다루는 산업 분야에서 가용성을 유지 하지 못하는 것은 치명적인 결과를 초래 할 수 있다. 이런 DSMS환경에서 고가용성을 유지하는 기법으로는 Active/Active 알고리즘과 Active/Standby기법이 있다. 하지만 이 기법들의 고가용성을 유지하기 위해 주 서버와 동일한 규모의 보조 서버를 유지해야 하는 단점이 있다. 본 논문에서는 질의를 두 가지 타입으로 나누어 누적 데이터가 필요한 질의들만 실시간 동기화를 통해 보조 서버에 유지하고 나머지 질의들에 대해서는 메타 데이터들만 보조 서버에 유지해 보조 서버의 규모를 줄일 수 있었다.

Today only 5-15% (approximately 1 in 10 persons) of persons with disabilities in need globally have access to assistive products which assist or replace the impaired functioning[1]. GATE (Global Cooperation on Assistive Technology) is a WHO global initiative for cooperation of stakeholders to cope with current and future challenges in product design, pricing, delivery and services, as well as medical and social system, expert training, and policies. This paper introduces the concept of WHO GATE to improve access to assistive technology for everyone by the cooperation with global key stakeholders.

The physical disabled are using various types of assistive devices and reading assistance device is have been researched and development. After all reading assistance device which being marketed present for the physical disabled's features is simply limited to turing the page. In this paper, Implemented prototype model of the reading assistance device for the physical disabled that is have designed to modify to improve the success rate of turing page and conjunction with mobile devices such as PDA to provide more convenient and useful features. And not only for the disabled then take a look at Universal design concept of view of the tool can be useful the public also.

모바일 상의 단문메시지 서비스는 등장한 이례 꾸준히 사용량이 증가하는 추세이며, 현재 세계적으로 가장 많이 사용되는 모바일 서비스이다. 모바일 기기에서 단문 메시지 작성의 불편함을 개선하기 위한 기술로 하드웨어적인 입력 방법 개선과 소프트웨어적인 입력보조 기능이 꾸준히 개발되었다. 소프트웨어적인 방법은 범용성이 넓고 적용이 쉽다는 장점이 있지만 제한된 자원에서 구현상의 어려움이 있어 연구가 미비한 분야이다. 본 논문은 소프트웨어적으로 단문 메시지의 작성을 보조하는 방법을 제시한다. 일상 생활의 반복성에 초점을 맞추어 반복 작성될 메시지에 대해 기존의 메시지를 제시해 자동적으로 응답하도록 하는 방법을 제안한다. 자동적으로 응답 메시지를 선택하기 위한 비교사 학습과 추론 기술로 "메시지 네트워크"를 제안하고, 실험을 통해 고안한 방법의 가능성을 보였다. 실험 결과로부터 반복적인 메시지의 작성에 제시한 방법이 유용함을 알 수 있었다.

The main purpose of this research is to identify limitations and problems in access to information using reading aids devices for the visually impaired and to suggest ways to activate the use of alternative materials using reading aids devices. A survey was conducted on adults with visual impairment in order to identify the factors of limitation in using reading aids devices. The analysis resulted in six aspects of limiting factors in activating the use of reading aids devices. The approaches for activating the use of reading aids devices were proposed by dividing them into policy and operational aspects, focusing on the limiting factors derived. Policy aspects suggested developing low-cost reading aids devices, increasing awareness of the devices, and complying with Web standard guidelines for improving the applicability of the devices, while operational aspects suggested reinforcing hearing-use functions, expanding information services related to reading aids devices, and enhancing portability of the devices.

The study is purposed to investigate the current status of assistive technology devices(ATDs) and to explore ways to improve the ATDs support system for work. As a method, domestic and foreign systems were investigated to derive implications can be applied in Korea based on the analysis framework that compromised Gilbert and Terrell's policy analysis model and research purpose. Next, a survey was conducted on 202 disabled supported ATDs for Work. They were looking for a job or working. We would like to suggest a plan as follows. First, it is necessary to improve the support process centered on consumers. Second, the expansion of items and supplementation of the quality management system should be considered. Third, it is urgent to expand the application qualifications. Finally, the foundation for improvement should be continuously laid. We expected the direction of improvement of the support system will be established.

In this paper, we propose S/W framework for health care robot based on OSGI middleware. Most healthcare robot developed independently. Therefore most module duplicately developed. However It's not efficient. In this paper we propose S/W framework for healthcare robot that can provide common module for health care robot and can apply heterogeneous robot. By using this S/W framework, we can enhance reusability of s/w module and can provide flexible and efficient development environment.
