Purpose: Visual impairment, hearing impairment, and masticatory discomfort each influence quality of life (QoL). However, little is known regarding the impact of their coexistence on QoL. Therefore, we aimed to investigate the influence of the coexistence of visual impairment, hearing impairment, and masticatory discomfort on QoL among middle-aged adults aged 40-64. Methods: This study involved a secondary data analysis utilizing the data from years 1 and 2 of the eighth Korea National Health and Nutrition Examination Survey. To evaluate the influence of the coexistence of visual impairment, hearing impairment, and masticatory discomfort on QoL, we conducted a complex sample hierarchical multiple regression analysis. Results: When visual impairment, hearing impairment, and masticatory discomfort coexisted, the QoL was significantly lower than in individuals without any of these conditions. Conclusion: The coexistence of visual impairment, hearing impairment, and masticatory discomfort was negatively correlated with QoL. Therefore, it is important to prepare for old age through appropriate health management during middle age.

Purpose: The purpose of this study was to identify the prevalence of visual and hearing impairment and to investigate the effect of visual and hearing impairment on depression and cognitive function in community-dwelling Korean elderly. Methods: The study population consisted of a representative community sample of 4,028 persons aged 65 and older from the Korean Longitudinal Study of Aging 2008. Depression and cognitive function were measured by CES-D 10-item scale and K-MMSE. Visual and hearing impairment were measured by 5-Likert scale. Data were analyzed using Rao-Scott ${\chi}^2$-test, simple and multiple logistic regression. Results: The prevalence of visual and hearing impairment were 37.3% and 14.0%, respectively. Of the participants, the prevalence of depression was 58.4% and cognitive impairment was 50.6%. There were significant differences in depression and cognitive function according to visual and hearing impairment. Far vision and hearing impairment were predictors for both depression and cognitive impairment even after covariates had been adjusted. Conclusion: These data suggest that visual and hearing impairment in older adults may increase their probability of experiencing depression and cognitive impairment. Thus sensory impairment should be considered a risk factor for mental health and the cognitive function of elderly.

Purpose: The aim of this study is to identify the influence of visual and hearing impairment on the activities of daily living of community dwelling elderly. Methods: Data were collected by home visiting interviewers from 452 older people aged 65 years or older living in community. Resident Assessment Instrument MDS-HC(2.0version) was used for data collection. Data analysis for descriptive statistics, Chi-square test and multiple regression was made by SAS 6.2 Results: 34.7% of the subject had hearing impairment and 64.3% had visual impairment Among IADL. one half of them were dependent in ordinary house work and meal preparation. In the case of ADL. 13.9% of subjects were dependent in bathing and 8.9% in personal hygiene. There was significant difference in IADL performance by visual and hearing impairment On the other hand, ADL performance showed the significant difference. only in the case of hearing impairment. As the result of input of visual and hearing impairment in the process of regression. variances were increased from 3% to 11%. Conclusions: Large proportions of older people living in the community have visual and hearing impairment. It could be confirmed that hearing and vision were significant factors influencing on IADL performance of older people. Intervention and support policy for elderly needs to focus on improvement of visual and hearing impairment.

In this paper, we propose a hearing impairment simulator considering reduced frequency selectivity and asymmetrical auditory filter of the hearing impaired, and we verified the reduced frequency selectivity and asymmetrical auditory filter affected in speech perception through experiments. The reduced frequency selectivity has made embodied by spectral smearing using LPC(linear prediction coding). The shapes of auditory filter are asymmetrical different with each center frequency. Hearing impaired person which has hearing loss was differently changed with that of normal hearing people and it has different value for speech of quality through auditory filter. The experiments confirmed subjective test and objective test. The subjective experiments are composed of 4 kinds of tests: pure tone test, SRT(speech reception threshold) test, and WRS(word recognition score) test without spectral smearing, and WRS test with spectral smearing. The experiment of the hearing impairment simulator was performed from 9 subjects who have normal ears. The amount of spectral smearing was controlled by LPC order. The asymmetrical auditory filter of proposed hearing impairment simulator was simulated and then some tests to estimate the filter's performance objectively were performed. The objective experiment as simulated auditory filter's performance evaluation method used PESQ(perceptual evaluation of speech quality) and LLR(log likelihood ratio) for speech through auditory filter. The processed speech was evaluated objective speech quality and distortion using PESQ and LLR value. When hearing loss processed, PESQ and LLR value have big difference according to asymmetrical auditory filter in hearing impairment simulator.

This study was conducted to determine the effects of horticultural therapy on self-esteem of women with hearing impairment. Ten women with hearing impairment registered in the Mokpo Branch of the Korean Association of the Deaf participated in the horticultural therapy programs (HTP) for self-esteem. The self-esteem scale was used to evaluate the effects of the programs and scores were compared to determine the difference before and after the programs. Self-esteem was improved in all 10 subjects, and its mean value increased with statistical significance from 22.5 points before the programs to 29.8 points after the programs. The programs preferred by women with hearing impairment included 'making a centerpiece using scented candles and flowers', 'packing and planting pot spray chrysanthemum', 'making a topiary', 'planting Hedera helix', and 'planting cyclamen'. Therefore, it was suggested that self-esteem of women with hearing impairment were improved by increasing social and family support, emotional stability, positive feedback, and self-expression through horticultural therapy programs.

Hearing loss is one of the most common birth defects among infants. Most hearing-impaired children are not diagnosed until one to three years of age, which is too late to treat for normal speech and language development. If a hearing impairment is identified and treated in its early stage, child's speech and language skills could be comparable to his or her normal-hearing peers. In this study, we applied the 'Fsp' method to distinguish between normal and impaired hearing. We have developed a battery-operated portable A - ABR(automated auditory brain stem response) system that automatically detects hearing impairment for neonates or infants in a nursery room, as well as in a sound-proof room. We partially validated the accuracy of the system in five normal-hearing adults.

In this paper, we propose a hearing impairment simulator considering reduced frequency selectivity of the hearing impaired, and verify it's performance through experiments. The reduced frequency selectivity was embodied by spectral smearing using linear prediction coding(LPC). The experiments are composed of 4 kinds of tests; pure tone test, speech reception threshold(SRT) test, and word recognition score(WRS) test without spectral smearing and with spectral smearing. The experiments of the hearing impairment simulator were performed with 9 subjects who have normal hearing. The amount of spectral smearing was controlled by LPC order. The percentile score of WRS test without smearing is $89.78{\pm}2.420%$. The scores of WRS with 24th LPC order and with 8th LPC order are $88.00{\pm}3.556%$ and $83.78{\pm}2.123%$ respectively. It is verified that WRS score is lowered by decreasing LPC order. This is a reasonable result considering that spectral smearing is getting heavier according to decreasing LPC order. It is confirmed that spectral smearing using LPC simulates the reduced frequency selectivity of the hearing impaired and affects the clearness of speech reception.
