Objective: The disabled are in a blind spot for obtaining information on drugs, and the pharmacies' counseling on drug use is centered on non-disabled people. Few studies have investigated the current statuses of drug use by type of disability. The purpose of this study is to understand the drug use by type of disability and by life cycle of visually impaired and hearing impaired in Korea. Methods: The study participants consisted of 16 people with visually impairments, 12 people with hearing impairments. One in-depth interview was conducted per participant, and each interview was recorded and documented. Results: Common barriers against safe medication and medical service uses across disability types are 'lack of consideration and service for the disabled, limited access to medical facilities due to disability, limited access to information regarding medication use, psychological anxiety about drug use and side effects, and inconvenience regarding COVID-19 epidemic. The specific factors were 'difficulties in identifying proper medicines and following prescribed dosages' in the case of visually impaired, and 'problems with sign language interpretation system' for the hearing impaired. Conclusion: Disabled people are hindered from using medicines properly due to various factors. Based on the content derived from this study, it is necessary to eliminate the inhibition factors and devise specific measures for the safety of each type of disorder such as developing a method for medication counseling considering disabilities and establishing communication support systems.

There are many assistive devices for the visually impaired. They are becoming smart. In this paper, we propose a device that help route guidance for a visually impaired person. It is composed of a smart phone, cane, and hands-free devices. The smart phone helps a route guidance. The cane detects an obstacle and transmits it to the hands-free device. The hands-free device communicates with a visually impaired person. We here present their architecture, signal flow, configuration, and their circuit diagrams.

The current Navigation System for the Visually Impaired Person has a short and limited communication distance and can't receive enough information from Visually Impaired Person to assist directly. In addition, because the path is dangerous and incomplete for the Visually Impaired Person, moving with White Stick is still inconvenient and dangerous. To solve this problem we implement communication that can send and receive video, voice, location information between the Visually Impaired Person's Android platform and assistant's PC.

This study examined the speech intelligibility of one-syllable words with phonetic contrasts and analyzed segmental factors that can predict the overall speech intelligibility in hearing-impaired adults. To identify the speech error characteristics, a Korean word list was audio-recorded by 7 hearing-impaired adults, and 35 listeners selected the heard word out of 5 choices. Based in part on previous studies of speech of the hearing impaired, the word list consisted of monosyllabic consonant-vowel-consonant (CVC) real word pairs. Stimulus words included 77 phonetic contrast pairs. The results showed that the percentage of errors in final position (coda) contrast was higher than in any other position in syllable. And the intelligibility deficit factors of phonetic contrast in the hearing-impaired were analyzed through stepwise regression analysis. The overall intelligibility was predicted by the error rate of manner contrast at coda, voicing contrast (homorganic triplets) at onset and high-low contrast at nucleus.

The changes of social climate in respecting differences and needs of each diverse groups and human equality have caused the disabled to persue quality of life, through enabling their lives more independent. The purpose of this research was to find out adequacy of the residence and living behavior of the hearing impaired. Though this reach it was expected to find out environment features which have become obstacle in maintain their life independent in normal way and the way of improving their environment. Small group workshop with three hearing impaired persons was implemented. Living behavior and physical environmental characteristic of dormitory and interaction between them were identified. The need of non auditorial communication for the hearing impaired found far beyond required guidelines of the disabled Act. Design professionals need more profound knowledge with and ethical and humanistic attitude to find and satisfy the need of disabled.

This study was analyzed to change of /i/ formant follow cochlear implantation periods for hearing impaired children with cochlear implantation. 20 hearing impaired children participated and acoustic analysis of /i/ was used CSL(Computerized Speech Lab; Model 4300b) annually. The data was captured the first formant, $2^{nd}$ & 3th formant frequency of /i/ and was analyzed using ANOVA. Multiple range test to investigate difference between group was treat with LSD and Duncan. The results of /i/ formant analysis for hearing impaired children with cochlear implantation, each formant at a year keeping with cochlear implantation was located at high frequency. In accordance with CI periods, the each formant decreased significantly, especially between a year and $2^{nd}$ year taking with cochlear implantation.

Purpose: The purpose of this study was to compare the levels of knowledge on 5 diseases between persons in hearing impaired and normal hearing groups. Method: The participants consisted of 44 people who are hearing impaired and 47 who are not. An instrument developed by the research team was used for data collection. The questionnaire consisted of 90 items including demographics and items on 5 diseases, hypertension, cancer, diabetes, pulmonary tuberculosis, and hepatitis. Results: The level of knowledge on the 5 diseases, hypertension, cancer, diabetes, pulmonary tuberculosis, and hepatitis in normal hearing group was significantly higher than hearing impaired group. Conclusion: More attention and comprehensive educational programs are needed for people with hearing impairment.

Background: This study was conducted to prove the effects of the Schroth exercise on sagittal postural alignment to the visually impaired students. Methods: The subjects were 8 students who attend the special school in Daegu and performed the Schroth exercise 3 times per week for 3 weeks. Craniovertebral angle and pelvic alignment were measured to compare the effects of the exercise. Results: Craniovertebral angle and pelvic alignment on sagittal plane showed significant differences (p<.05). Conclusions: Schroth exercise was effective to improve postural alignment of sagittal plane to the visually impaired students and these results will have a positive impact on future study of improvement of postural alignment on sagittal plane to the visually impaired students.

People with visual disabilities suffer environmentally, socially, and technologically. Navigating through places and recognizing objects are already a big challenge for them who require assistance. This study aimed to develop an android-based assistive application for the visually impaired. Specifically, the study aimed to create a system that could aid visually impaired individuals performs significant tasks through object recognition and identifying locations through GPS and Google Maps. In this study, the researchers used an android phone allowing a visually impaired individual to go from one place to another with the aid of the application. Google Maps is integrated to utilize GPS in identifying locations and giving distance directions and the system has a cloud server used for storing pinned locations. Furthermore, Haar-like features were used in object recognition.

The severe-profound hearing impaired children have various disorders in everday communication due to the lack of hearing feedback. Especially, their speech produced unstable voice, omission and distortion of articulation, pitch break, cul-de-sac voice, and so on so that they were difficult to accurately deliver an intended message. This study attempts to analyze the acoustic characteristics of 4 vowel sounds produced by 35 severe-profound hearing impaired children using CSL(Computerized Speech Lab, Model 4300b). The formant data were obtained from the spectrogram and analyzed data by 12 formant filter and auto-correlation among the formants. Results showed that the hearing impaired children's formant values came out very high. They produced the vowels at the mode of hypertension with unstable voice. In order to improve their speech, they would need some adequate auditory feedback.
