This paper was studied on developmental direction of telecommunications for disabilities welfare. Method of this study is delphi method. Persons with disabilities is classed as motor disability, visual handicap, hearing impairment, and language and speech disorders. Persons with motor disability is needs as follow, speed recognition technology, video recognition technology, breath capacity recognition technology. Persons with visual handicap is needs as follow, display recognition technology, speed recognition technology, text recognition technology, intelligence conversion handling technology, video recognition - speed synthetic technology. Persons with hearing impairment and language - speech disorders is needs as follow, speed signal handling technology, speed recognition technology, intelligence conversion handling technology, video recognition technology, speed synthetic technology the results of this study is as follow: first, disabilities telecommunications organization must be constructed. Second, persons with disabilities in need of universal service. Third, Persons with disabilities in need of information education, Fourth, studying for telecommunications in need of support. Fifth, small telecommunications company in need of support. Sixth, software industry in need of new development. Seventh, Persons with disabilities in need of standard guideline for telecommunications.

Most of information and communication assistance machinery and tools for disorder people of Occupied are machinery and tools for a visual impairment person and software, The things which can apply to only a specification disorder type and a specification disorder part are most, A special keyboard or a special mouse device of the handicapped person that disorder rank is comparatively the hardness makes the mainstream. It is reported in diffusion rate being very low if I compare this with total disorder population. I study new 1 plan which it can be applied to various disorder types and disorder parts through an intelligent special input device in a study of a book and, I designed this at the real standard that I could manufacture and incarnated it. In addition, I suggested this in a base for a design of a universal supporting input device and suggestion for the side of incarnation plan and a future study direction.

In this paper, we propose an enhanced p-cycle (preconfigured protection cycle) scheme for WDM mesh networks with QoS constraints. In the previous researches on p-cycle, it is assumed that user's connection has a hi-directional connectivity and the same bandwidth on both direction. Therefore it is difficult to apply p-cycle based link protection to uni-directional connections for multicasting or asymmetric broadband multimedia communications with hi-directional connectivity. And it didn't consider QoS of backup path. We enhanced the p-cycles to accomodate uni-directional connections for multicasting or asymmetric bandwidth communications with hi-directional connectivity. And we propose a selection procedure of p-cycle to assure QoS of backup path. We were able to reduce a required backup bandwidth by applying a uni-directional p-cycle concept to asymmetric broadband multimedia communication environment. The proposed p-cycle selection procedure is applied to the U.S. sample network to evaluate whether the configured p-cycles can support QoS constraint of working path and backup path.

최근 고령인구와 장애인구에 대한 사회적 배려나 관심이 지속적으로 증가로 인하여 이들에게 실질적인 혜택을 주기위한 기술적 발전과 그에 따른 산업 변화가 일고 있다. 거리에서 쉽게 볼 수 있는 거리의 음성신호를 장착한 신호등에서부터 공중전화, 자동차에 이르기까지 다양하다. 그 중에서 특히 장애인이나 노인들에게 제공되는 정보통신에 대한 시책들은 아직은 미흡하다.

광통신은 인터넷 이용자의 증가와 디지털기술 발전에 의한 화상정보 활용의 보편화, 전자 상거래, 양방향 TV등 전송 데이터가 폭증하는 정보화 사회의 필수적인 기술이다. 이는 광섬유 한 가닥의 정보전달 능력이 수십 Gbps이며 전자파 장애에 의한 누화나 잡음이 없고 수명이 길다는 장점이 있기 때문이다.
