This study was performed to understand the depression of children with hearing impairment with relation to their mothers' nurturing attitude and sign language level. The subjects were 131 hearing impaired children aged from 9 to 16 years and their mothers, who had no hearing impairments. The children's depression was assessed by CDI(Kovacs 1983) adapted by Cho and Lee(1990), and the maternal attitude was measured through the instrument developed by Oh and Lee(1982) and revised by Lim(1987). The results were as follows. First, the girls' depression was higher than the boys', and children in a dormitory type of school showed higher depression than those in a general type of school. Second, children's depression did not show differences according to mother-child communication methods but differed according to mothers' sign language level. Children whose mothers had high level of sign language showed the highest depression and those whose mothers had beginning level of sign language showed the lowest depression. And mothers' affective, goal- achieving and rational attitude were negatively related with children's depression. Third, the depression of hearing impairment children was influenced mainly by the maternal affective attitude, and the next order was the type of school the children attend.

With the advent of high speed digital signal processing chips, new digital techniques have been introduced to the hearing instrument. This advanced hearing instrument circuitry has led to the need or and the development of new fitting approach. A number of different fitting approaches have been developed over the past few years, yet there has been little agreement on which approach is the "best" or most appropriate to use. However, when we develop not only new hearing aid, but also its fitting method, the intensive subject-based clinical tests are necessarily accompanied. In this paper, we present an objective method to evaluate and predict the performance of hearing aids without the help of such subject-based tests. In the hearing impairment simulation (HIS) algorithm, a sensorineural hearing impairment model is established from auditory test data of the impaired subject being simulated. Also, in the hearing impairment simulation system the abnormal loudness relationships created by recruitment was transposed to the normal dynamic span of hearing. The nonlinear behavior of the loudness recruitment is defined using hearing loss unctions generated from the measurements. The recruitment simulation is validated by an experiment with two impaired listeners, who compared processed speech in the normal ear with unprocessed speech in the impaired ear. To assess the performance, the HIS algorithm was implemented in real-time using a floating-point DSP.

Background and Objectives: To investigate the relationship between hearing impairment and alcohol drinking patterns in South Korean adults. Subjects and Methods: Data collection was performed by Korean National Health and Nutrition Survey from January 1 to December 31, 2012. Data analyses were performed from February 20 to March 3, 2018. Data from 3,860 adults 20 years of age or older without a history of malignancy or chronic otitis media in the Korean National Health and Nutrition Survey 2012 database who participated in the health questionnaires, and who had available results from otologic examinations that included pure tone audiogram, were included. Pure-tone average hearing thresholds were calculated at 500, 1,000, 2,000, and 4,000 Hz. Hearing loss was defined as a pure-tone average >40 dB in one or both ears. The Alcohol Use Disorder Identification Test was used to evaluate drinking statuses of subjects. Data were analyzed using the complex-sample χ²-test of independence and a complex-sample logistic regression analysis. Results: Of the 29,954,319 individuals in the weighted cross-sectional study population, 15,106,040 (50.4%) were men and 14,848,098 (49.6%) were women. A total of 8.1% of men and 7% of women had hearing impairment. The degrees of drinking with appropriate, risky, and hazardous drinking habits were 58.2, 32.1, and 9.7% among men; and 76.4, 12.5, and 11.1% among women, respectively. Among men, the odds ratio of hearing loss increased by 2.506 times when comparing hazardous and appropriate drinking (confidence interval, 1.083 to 5.800, p=0.002). Moderate alcohol consumption (≤2 drinks per day) was not protective for hearing in either group. Conclusions: As hazardous drinking tends to coexist with hearing impairment in men, appropriate prevention and intervention strategies should be emphasized. A longitudinal study to investigate harmful drinking and the mechanism of hearing loss should be performed.

The purpose of this study was to investigate correlation of auditory development and language development of children with hearing impairment Eighteen subjects with severe or profound hearing loss participated in this study. They were 22-to 55-month-olds who had hearing parents with no additional disabling conditions. The test material was the Meaningful Auditory Integration Scale (MAIS) and MacArthur Communicative Development Inventory-Korea (MCDI-K). A Pearson Correlation Coefficient was determined through a statistical analysis. The results followed as; firstly there was a strong correlation between auditory development and receptive language development. Secondly, there was a strong correlation between receptive language development and expressive language development. Finally, there was a strong correlation between auditory development and education onset time. Therefore, auditory training is important method for auditory rehabilitation and education onset time is important variation for auditory development.

Background In microtia patients with bilateral hearing impairment, hearing improvement is crucial for language development and performance. External auditory canal reconstruction (EACR) has been performed to improve hearing, but often results in complications. We performed transcutaneous bone conduction implant (TBCI) surgery in these patients. This study aimed to evaluate the safety and efficacy of TBCI surgery. Methods A retrospective review was performed of five patients who underwent auricular reconstruction and TBCI surgery and 12 patients who underwent EACR between March 2007 and August 2018. Hearing improvement was measured based on the air-bone gap values using pure-tone audiometry over a 6-week postoperative period. We reviewed other studies on hearing improvement using EACR and compared the findings with our results. The surgical techniques for TBCI were reviewed through case analyses. Results Postoperative hearing outcomes showed a significant improvement, with a mean gain of 34.1 dB in the TBCI cohort and 14.1 dB in the EACR cohort. Both gains were statistically significant; however, the TBCI cohort showed much larger gains. Only three of the 12 patients who underwent EACR achieved hearing gains of more than 20 dB, which is consistent with previous studies. All patients who underwent TBCI surgery demonstrated hearing gains of more than 20 dB and experienced no device-related complications. Conclusions TBCI is a safe and effective method of promoting hearing gains in microtia patients with bilateral hearing impairment. TBCI surgery provided better hearing outcomes than EACR and could be performed along with various auricular reconstruction techniques using virgin mastoid skin.

Objectives: Reproductive health education is essential for adolescents with hearing impairment. Since they communicate using specialized language (i.e., sign language), specialized reproductive health services in sign language is a necessity. This study aimed to describe the needs, availability, and expectations of reproductive health services among adolescents with hearing impairment. Methods: This study used a qualitative approach. It was carried out at a school for children with special needs in the city of Denpasar, Bali, Indonesia. Data were collected by in-depth interviews. The informants were 6 adolescents with hearing impairment aged 16-17 years and 4 other key informants, including school staff and health officers. The data were then analyzed using the thematic method. Results: We found that the informants had insufficient knowledge regarding reproductive health. There was no specific subject in the curriculum regarding this issue. Teachers did not specifically provide reproductive health information. The health service unit in the school had not been utilized well for this purpose. Furthermore, no reproductive health services were provided due to the limited number of healthcare workers who could use sign language. Conclusions: The awareness and intentions of adolescents with hearing impairment regarding access to reproductive health services remain low. Health service units at schools should be optimized to enable schools to provide reproductive health information and services for these adolescents.

This study was conducted to examine the effects of horticultural therapy on depression and emotional balance of women with hearing impairment. Ten women with hearing impairment registered in the Mokpo branch of the Korean Association of the Hearing Impaired were selected, and participated in the horticultural therapy program composed of 14 sessions from May 15 to July 31. The horticultural therapy program consisted of 'planting tropical orchids,' 'making a dish garden,' 'making plum pickles,' 'decorating a table with flowers,' 'making a hanging pot with succulent plants,' 'making pressed flowers with hydrangea,' 'making a fan with pressed flowers,' 'making a terrarium,' 'making a flower basket,' 'making a mosquito repellent spray,' 'decorating a heart-shaped cup with flowers,' 'making a natural herbal soap,' 'making a hydrangea bouquet' and 'making watermelon salad.' The depression and emotional balance scales were used to examine the effects of the program and the pre- and post-program scores were compared. The mean value of depression statistically significantly decreased from 49.0 points before the program to 43.9 points after the program. In addition, the mean value of emotional balance statistically significantly increased from 0.3 points before the program to 2.3 points after the program. The activity of drawing a picture after each session was effective in reducing depression and improving positive emotional balance by expressing emotions through pictures. The programs preferred by women with hearing impairment included 'making plum pickles,' 'making pressed flowers with hydrangea,' 'planting tropical orchids,' 'making a mosquito repellent spray,' 'making a natural herbal soap,' and 'making watermelon salad.' In conclusion, horticultural therapy programs were effective in reducing depression and improving emotional balance of women with hearing impairment.

Music is a means of emotional expression and self-expression. In addition, it allows to interact with others and communicate with the world. Music may be considered as inaccessible for people with hearing impairment, who are sometimes discriminated from the music community. We explore trends in various technologies and research that enable everyone to access and enjoy music through experiences that leverage new and innovative technological approaches and bridge the gap between people with and without hearing impairment. Various aspects of haptic systems are being studied, but most of them are performance-oriented and focus only on technical functions. As research matures, more detailed and new studies that converge with various senses are being attempted. These studies will likely evolve into influential research areas that can positively affect the lives of people in terms of accessibility and inclusion by providing detailed functions and stimuli to specific users, including those with hearing impairment.
