This study was carried out to compare the rotation between vestibular function and balance skills in normal and hearing-impaired children. The subjects were 20 normal children (8-10 years) and 20 bearing-impaired children (8-10 years). The SCPNT was used to assess vestibular function, then, one leg stance test was used to compare static balance skill of normal and hearing-impaired children according to existence of visual input and sex. The results were as follows: 1. In SCPNT, normal md hearing-impaired children showed statistical significance in all left-sided and right-sided rotations(p<.01), and the vestibular function responses of hearing-impaired children wore normal $20\%$, abnormal $45\%$, absent $35\%$. 2. To compare balance skills between normal and hearing-impaired according to eye open and eye close, one-leg stance Oat showed statistical significance in eye open(p<.05), but did not show statistical significance in eye close(p>.05). 3. SCPNT, ene-leg stance test did not show statistical significance according to sex(p>.05).

This study investigates the differences in nasalance across handicap, gender, and vowels and the correlation between nasal energy and oral energy both of which are used to compute nasalance. For this study, 20 hearing-impaired adults and 20 normal hearing adults as a control group were asked to read 7 Korean vowels (/$\alpha$, $\Lambda$, o, u, ɯ, i, $\varepsilon$/). Subjects' readings were recorded by NasalView and analyzed by Praat. Results showed that the hearing impaired group (HL) has a significantly higher nasalance than the normal hearing group(NH), and that there was a significant positive correlation between nasal energy and oral energy. A higher nasalance of the hearing impaired group seems to be due to an improper velopharyngeal control which is caused by lack of a proper auditory feedback.

Objective: Because of communication difficulties, the hearing-impaired face many disadvantages throughout their lives. One of those is limited access to health care services, particularly medication service. Though they suffer from problems related to taking medication properly, there have been few studies on their actual condition of medication use in Korea. This study is to investigate any obstacles to properly taking medications and, therefore, to suggest preliminary evidence for policy measures to improve safe medication use among the hearing-impaired. Methods: Study participants consisted of hearing-impaired individuals living in Seoul. We also interviewed two sign language interpreters in order to illuminate health care state of the hearing-impaired. In-depth interview for each study participant was recorded and was translated into a written script for analysis. Results: Study participants were comprised of four women (66.6%) and two men (33.3%). There were one participants in 20's, two participants in 30's, one 40's, and two 50's. Sign language interpreters were all women. One was in her 30's and the other was in her 40's. Communication difficulties have been found to be key barrier to use medication safely. A negative image of pharmacists also hinders safe medication usage, lowering access to local pharmacy and leading discretional self-medication. This article provides pharmacists with solutions to promote adherence in this population. Conclusion: The hearing-impaired had limited access to medication-related information as well as using services in a hospital and local pharmacy due to their disability. Institutional improvement for safe medication usage among the hearing-impaired is necessary.

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.

The purposes of this experiment were to compare and analyze some voice parameters of the hearing impaired male adults and to suggest a basic data on the speech intervention for the hearing impaired. Voice analysis of four sustained vowels(/a/, /i/, /${\partial}$/, /u/, fundamental Sequency(F0), jitter percent, shimmer percent, and Noise to Harmonic Ratio(NHR) was conducted for the deaf young male adults using a sign laguage(N=5, aged 16-20) and the normal hearing young male adults(N=10, aged 18-20) by using MDVP(Multi-Dimensional Voice Program) in CSL. F0, jitter, and shimmer in the deaf group were significantly higher than those in the normal hearing group. The average of F0 was 151 Hz, which was lower than the results of the previous studies, and there were no significant differences among the sustained vowels. In both groups, the values of the voice parameters were stable on the /a/ or /${\partial}$/, those closed to the standard scores.

To provide ameliorated aided environment to hearing impaired listeners, background noise reduction techniques are investigated as a front-end of conventional hearing aids, and their effects are tested in a subjective manner. Several speech enhancement schemes were implemented and preference tests or normal listeners are performed to select the best possible scheme or hearing impaired listeners. Results indicated that SDT scores without the speech enhancement scheme drop more sharply as SNR decreases than those with the speech enhancement techniques. SDT scores obtained or hearing impaired listeners with hearing aids showed large variability. However, all impaired listeners preferred noise suppressed sounds to unsuppressed ones.

Auditory and language train for the hearing-impaired is an essential course improving conversational capability with non-deaf and accompanying the financial burden and the physical fatigue of parents or a teacher. To reduce these problems, web-based training contents have been developed. But these contents have been developed without consideration of individual difference such as various levels of residual hearing and the learning capability of hearing-impaired. Therefore, it is important that appropriate training progress for each hearing-impaired should be designed by evaluating and analyzing the personal status, residual hearing, learning capability and training achievement. This paper suggests auditory and language training service model for the hearing-impaired, which is planning and managing an auditory and learning training based on personal evaluation. In addition, this paper suggests a design method for a serious game content planing based on this service model.

This study measured formant bandwidths of profound hearing impaired children and examined the characteristics of their articulation. For this study, 10 cochlear implanted children(CI), 10 hearing aid children(HA) and 10 normal hearing children(NH) were asked to read 7 Korean vowels(/ɑ, ʌ, o, u, ɯ, i, ɛ/). The subjects' readings were recorded by NasalView and analyzed by Praat. The analysis of the formant bandwidths explains the degree of vocal fold opening and the characteristics of radiation. Through the analysis of formant bandwidth, we can see that the hearing-impaired maintain vocal fold tension when they speak high vowels and characteristics of radiation. Narrower B1 means better maintain vocal fold tension, wider B2 means more front and wider B3 means the rounder lips. CI's B1 was widest and NH's was narrowest. And females' B1 was wider than males'. Among vowels, B1 of /a/ was widest, and B1 of /i/ was narrowest. In the case of B2, HA and NH's B2 was wider than CI's. Females' B2 was wider than males'. And B2 of /i/ was widest, and B2 of /ʌ/ was narrowest. In the case of B3, NH's was widest, and CI's was narrowest. Males' was wider than females'. Among vowels, B3 of /o/ was widest, and B3 of /ɛ/ was narrowest. As a result, first, through the analysis of B1, we can find that NH and males could better maintain vocal fold tension than the hearing-impaired or females, and all children articulate /i/ with vocal fold tension than other vowels. Second, through the analysis of B2, NH and HA articulate vowels with the weaker rounded than CI does. And females articulate vowels with the weaker rounded than males do. Third, through the analysis of B3, NH articulate vowels with the rounder than HA or CI do, and males articulate vowels with the rounder than females do. Through the results, we can expect that the analysis of formant bandwidth will be applied to the therapy of articulation for the hearing-impaired with hearing aids or cochlear implant.

This paper describes characteristics of a bone conduction telephone which was developed for conductive hearing impaired persons to call without additional devices and results of its performance test. Not only the hearing impaired but also normal hearing persons can use this telephone because we developed a bone conduction vibrator with which they can perceive speech signal using functions of air conductive hearing as well as bone conductive hearing. It also has tone control function compensating hearing losses for the hearing impaired originating from their hearing characteristics, and using this function together with received volume control it has received volume range of 20dB in loudness rating, which is similar effect as what a telephone set with built-in received amplifier has. From results of articulation and intelligibility tests for 19 hearing impaired persons, we can see that if their bone-conduction hearing loss is 61dB or less, they can understand words or sentences and response well with this telephone.
