본 연구에서는 일반 전화기 사용이 어려운 신체 장애인을 위하여 하나의 스위치를 이용하여 전화기를 사용할 수 있는 스캐닝 전화기를 개발하였다. 개발된 전화기는 일반 전화기와 스캐닝 해주는 메뉴와 번호를 LED와 LCD를 통하여 보여주는 스캐닝 전화기 그리고 스위치로 구성된다. 스캐닝 전화기를 제어하고 일반전화기 연결 해 주기 위하여 ATmega128을 사용하였으며 시스템의 입출력을 제어하기 위하여 아날로그 스위치와 디코더를 사용하였다. 개발된 시스템을 이용하여 성능평가를 한 결과, 설계한 바와 같이 하나의 스위치를 이용하여 전화기의 모든 기능의 사용이 가능하였으며 다양한 스위치와도 호환이 잘 되었기 때문에 손 이외의 머리나 발 등으로 사용이 가능하였다. A scanning telephone was developed for physical disabled people who has difficulties. User can select menu and number of telephone using a switch. The developed telephone consists of a manual telephone, a scanning telephone and a switch. the users can see the information on telephone menu and numbers through LED and LCD placed on the scanning telephone. AVR RISC processor ATmega128 was used to design control part of the scanning telephone, decoder and analog switches was used to control input/output of this system. After the system was implemented, the performance test was carried out. The user could control all functions of system with a switch as it has designed. Also the user could change the manual switch for any alternative switch which is very appropriate for individual. It allows user with severe disabilities to call their care-giver when the emergency occurs. From the result, the system will be adaptable for people with disabilities as well as aged people.

Recently, the importance and interest about the assistive devices and assistive technology service for rehabilitation is being increased. Many people with disabilities are using suitable assistive devices to assist and get over their disadvantage. But most of the assistive device was standardized and it doesn't fit often to individual situation and condition. Therefore, the assistive devices should be modified to fit the user's condition and life environments. In this paper, we provided an assistive technology service for a child who has some difficulties about communication and learning due to the Cerebral Palsy. A switch was modified for him to help to cognize and express something. The switch was designed to be controlled by his finger which is unique method to move freely. After that, the child could freely communicate with other and the learn and read a book using the device by himself. Therefore, the learning ability was greatly improved and we expect that he will easily adapt to social life. 많은 장애인들이 자신에게 적합한 보조기기를 사용하고 있고 그 수가 증가하고 있지만, 이러한 현재 시중에 나와 있는 보조기기들은 표준화 되어 있기 때문에 개개인의 환경과 상태에 적합하지 않다. 이 문제를 해소하기 위해서는 보조공학 서비스가 필요하다. 본 논문에서는 뇌성마비로 인하여 의사소통 및 학습이 어려운 아동에게 학습에 도움을 주는 보조공학 서비스를 적용하고 평가하였다. 인지능력은 있지만 자신의 의사를 말로 하지 못하고 자신의 신체를 자의적으로 움직일 수 없는 아동에게 제약적이나마 움직임이 가능한 손 부위를 이용하여 컴퓨터를 사용할 수 있도록 스위치를 개조하여 적용해 주었다. 그로 인해 아동은 적용해 준 스위치를 이용하여 학습에 필요한 의사표현을 할 수 있고 책도 읽을 수 있게 되었다.

For the handicapped person who is in a difficulty of speech communication by cerebral palsy(CP), an augmentative and assistive communication (AAC) equipment was designed, implemented and applied. The AAC equipment was designed to generate recoded voice that is matched to the pressed word plate. A handicapped person by CP have been selected and after investigation of her disabled condition, the equipment was considered to be put on the knee of user who have to sit at a wheelchair. For the low power consumption, a PIC16F84 micro controller was used in the control module of the AAC and an IC record & play kit was used for the voice recording and generating the sound. The implemented equipment was tested by the selected disabled and it was verified that the AAC equipment have suitable performances as designed concept. 뇌성마비로 인하여 의사소통이 힘든 아동이 자신의 의사를 표현할 수 있도록 도와주기 위하여 원하는 단어판을 누를 경우 해당하는 음성을 소리로 발생시킴으로써 대화가 가능하도록 하는 대체의사소통기구를 설계, 제작하였다. 선정된 대상아동의 장애상태를 확인한 후 사용할 수 있는 왼쪽 손을 이용하여 포인팅 함으로써 자신의 의사를 전달할 수 있도록 하였으며, 발생하는 음성을 의미하는 그림이 그려진 단어판 스위치를 직접 입력할 수 있도록 함으로써 가정에서 원하는 대화를 가능하도록 설계하였다. 의사소통기기의 제어기는 PIC16F84를 이용하였고, 음성출력기는 20초 이내의 범위에서 직접 녹음할 수 있으며 저전력으로 동작하는 집적회로를 이용한 음성 녹음 및 출력기를 사용하였다. 기기제작 후 대상아동에게 사용함으로써 설계된 계획에 맞도록 의사소통기기가 양호하게 동작함을 확인하였다. 앞으로 이러한 기기의 성능개선을 실시할 경우 현재 외국에서 수입되고 있는 값비싼 의사소통기기를 대체할 수 있는 가능성을 확인하였다.

Proposal of a Simultaneous Ultrasound Emission for Efficient Obstacle Searching in Autonomous Wheelchairs

Byung Seop Song,김창걸 대한의용생체공학회 2013 Biomedical Engineering Letters (BMEL) Vol.3 No.1

Purpose Highly disable patients, who use the powered wheelchair, require an autonomous wheelchair for movement. Fundamental problem of the autonomous wheelchairs is safety. In order to dodge the obstacles, efficient searching method of the obstacles is necessary. Methods The proposed method utilizes multiple ultrasound emitters that generate signals of identical frequency and intensity. Corresponding sensors detect the reflected ultrasound signals, and the position of the obstacle is calculated based on the time of flight (TOF) of the ultrasound wave. It was carried out the obstacle searching experiments with proposed method. Results The results showed that the proposed method’s errors are within 1~2% which is much lesser than the general scan method. Therefore, the proposed method is suitable for autonomous wheelchairs as it facilitates detection of the nearest obstacle, and yields more accurate estimation of the position. Conclusions Therefore, the proposed method based on a simultaneous emission strategy is suitable for autonomous wheelchairs as it facilitates detection of the nearest obstacle,and yields more accurate estimation of the position.

<B>Object</B><P>Glioblastoma is the most common primary malignant brain tumor; however, glioblastoma in children is less common than in adults, and little is known about its clinical outcome in children. The authors evaluated the long-term outcome of glioblastoma in children.</P><B>Methods</B><P>Twenty-seven children were confirmed to have harbored a glioblastoma between 1985 and 2007. The clinical features and treatment outcomes were reviewed retrospectively. All patients underwent resection; complete resection was performed in 12 patients (44%), subtotal resection in 12 patients (44%), and biopsy in 3 patients (11%). Twenty-four patients (89%) had radiation therapy, and 14 (52%) patients received chemotherapy plus radiation therapy. Among the latter, 5 patients had radiation therapy concurrent with temozolomide chemotherapy. Four patients with small-size recurrent glioblastoma received stereotactic radiosurgery.</P><B>Results</B><P>The median overall survival (OS) was 43 months, and the median progression-free survival was 12 months. The OS rate was 67% at 1 year, 52% at 2 years, and 40% at 5 years. The median OS was significantly associated with tumor location (52 months for superficially located tumors vs 7 months for deeply located tumors; p = 0.017) and extent of removal (106 months for completely resected tumors vs 11 months for incompletely resected tumors; p < 0.0001).</P><B>Conclusions</B><P>The prognosis of glioblastoma is better in children than in adults. Radical resection followed by concurrent chemoradiation therapy may be the initial treatment of choice.</P>
