  • Hearing impaired people are apt to be in danger because they can't detect danger with sound. Hearing impaired people have less risk-detection ability than non-disabled people because of lack of hearing. There are many devices to help the hearing impaired, such as hearing aids. A hearing aids can be helpful, but it may not be available depending on the degree or type of hearing loss for example, to the hearing-impaired people with little remaining hearing of high frequencies, ordinary hearing aids are not very useful for understanding the high frequency consonants and it requires a high cost, from thousands to tens of thousands of dollars. Also, it is difficult for the underprivileged, such as the low-income bracket and the elderly, to use them because they are difficult to manage. Therefore, this paper describes the development of low-cost wearable device to assistant a hearing-impaired people using Arduino. Also, it accepts values from switches or sensors and can control external electronic devices such as LEDs and motors to create objects that can interact with the environment. In this is paper, through sound sensors, the ambient sound was taken as an analogue value and transmitted to the aduino board, and the vibration motor was operated when the noise was generated, so that the user could be aware of the occurrence of danger.

  • Disasters are now becoming commonplace and especially the vulnerable group such as the disabled, the elderly, children and foreigners are in a state of overlapping disasters. In this situation, ATSC 3.0-based UHDTV disaster information service for the visually and hearing impaired has been developing. This study focuses on the demand data collected through in-depth interview with the impaired. The demand analysis data is very important to development process of technology. The results of the interview show that it is essential to link the UHDTV disaster signals with home-network, IoT, wearable devices, and various assistive devices for the impaired (hearing aid, smart light bulbs, warning light, etc.). In outdoor space, UHDTV disaster information must be connected to public display media, digital signage, kiosk, screens in bus or taxi. If communication aids for the visually and hearing impaired are equipped with a function that can transmit and receive disaster information, it will help to minimize disaster damage.

  • 청력장애인이 전화상의 말에 대한 청취력을 향상시킬수 있는 보청기능이 있는 전화기를 개발하였다. 최근 청력장애인이 늘어나고 있으며 생산자로서의 사회참여 욕구 또한 늘어나고 있는데 이들은 자신의 핸디캡을 메워줄 보조기기를 강력히 원하고 있다. 보청기능 전화기는 음성으로써 외부 정보를 획득할 수 있는 기본적인 통신 보조기기의 한 형태이다. 본 연구팀은 청력장애인의 청력특성을 분석하고 전화기에 청력 보상법을 적용함으로써 보청기능이 있는 새로운 모델의 전화기를 개발하였고 3가지 분야의 시험(전기적 시험, 단어 인지도 시험, 사용자 시험)을 수행하여 이 전화기의 유용성을 평가하였다. 새 전화기는 4개의 대역통과필터를 가지고 있으며 각 밴드의 중심주파수는 전화라인의 특성과 심리음향학적인 특성을 고려하여 500, 1000, 2000, 3000 Hz로 설정하였다. 청력장애인은 전화기의 증폭특성을 자신의 청력에 맞도록 피팅(fitting)할 수 있다. 즉 자신의 손실된 청력을 잘 보상하도록 4개 필터밴드에 대한 볼륨조절을 개별적으로 조정할 수 있다. 전화기의 전체 이득은 250~32000Hz 대역내에서 20㏈ 이상이다. 시험결과 새 모델의 전화기가 기존의 전화기보다 청력장애인의 전화음성 이해도를 향상 시킨다고 증명되었다. 향후 측음 및 잡음 억제, 주파수 대역분리, 청력패턴 보상과 심리음향적 라우드니스(loudness)보상에 대한 연구가 필요하며 공학과 임상 분야에서의 청력장애인의 언어 이지특성 연구를 통하여 더욱 발전된 전화기가 개발될 수 있다고 판단된다.

  • The impaired person and the elderly who has hearing loss have been continuously increased and these people's desire for participating society as a producer has been increased also. So they strongly request the aid device which can compensate their handicap. The healing aid telephone is one of the basic aid devices that helps the hearing impaired to communicate with other people and to acquire useful information. We design the new model of the hearing aid telephone and test it's efficiency in three fields - electrical, speech perception, user test. From the result of the test we certify that the new model is better for the hearing impaired to understand the meaning of telephone speech than the old general models. We expect that the advanced healing aid telephone can be developed by the research about speech perception characteristics of the hearing impaired in engineering and clinical side.

  • The purpose of the study was to analyze the functional status of low income elderly living at home according to their socio-economic factors, sensory function, health status, medical service utilization, commodity and types of chronic disease. Method: Functional status was defined by the level of mobility, ADL and IADL categorized as independently functional, mildly impaired, moderately disabled, and severely disabled. The data was collected by home-visit interviews with 567 community dwelling adults who were 65 years of age or more with low a income status subsidized by government in ChonAn. Results: 9.9% of community dwelling older adults were severely disabled, and 44.4% were moderately disabled in their functional status. There were significant differences in the functional status by age, education, religion, and types of family structure. The older adults with hearing impairment or dental problems had a significantly higher rate of severe disability. Self-rated health status and medical service utilization were also significant factors to the differences in functional status. The functional status of older adults was also significantly related to the presence of chronic health problems such as chronic back pain, stroke, and Alzheimer-dementia. Conclusion: The results confirmed that community dwelling older adults with low income status were more functionally disabled in comparison to general older adults at national level, while the relating factors to their functional status seemed similar to other studies on older adults. Further studies were suggested to look into functional status longitudinally and focus on the changes of functional status by managing modifiable influencing factors.
