Purpose: The purpose of this study was to investigate the effects of an education program on health promotion behavior for students with hearing impairments. Method: For this study a nonequivalent control group pretest-posttest design was used. The three components of the study were: 1) the recognition of the importance of health promotion behavior, 2) formation of supportive networks, and 3) practice of health promotion behavior. The study population consisted of 38 students with hearing impairments (experimental group [19], control group [19]). The program was provided to students in the experimental group for 50-120 minutes, once a week for 3 weeks. Descriptive statistics, $X^2$-test, t-test, Fisher's exact test, and ANCOVA were used to analyze the data. Results: Perceived social support and health promotion behavior, but not self efficacy, were significantly different between the two groups. Conclusion: The result of this study indicate that this education program for health promotion behavior was effective for promoting perceived social support and health promotion behavior in students with hearing impairments, but further continuous research is needed to identify effective interventions to promote health behavior in students with hearing impairments and to allow for generalization of the results of this study.

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.

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.

Background and Objectives The main objectives of this study were to determine the clinical usefulness of the program-assisted and real ear measurement (REM)-assisted fitting of hearing aids. Subjects and Method Fifteen participants with moderate to moderately severe hearing loss were enrolled in this study. Objective and subjective fitting results were assessed to compare the benefits between the program-assisted fitting (using a software fitting program) and the REM-assisted fitting. Real ear insertion gain (REIG), sound-field audiometry using warble tone, and Korean Hearing in Noise Test (K-HINT) were performed as objective tests. Sound quality rating was performed as a subjective test. Results In the program fitting, 48.89% of fitting points failed to come within ${\pm}10dB$ of the REIG target. In the REM fitting, however, the percentage of failure significantly decreased to 23.33% (p=0.013). In K-HINT test, the reception threshold for speech in quiet situation significantly decreased from 50.1 dB HL with the program fitting to 44.7 dB HL after the REM fitting (p<0.001). In front noise condition, signal-to-noise ratio improved from 4.53 dB to 3.50 dB with the REM fitting without statistical significance (p=0.099). In the sound quality rating, the REM fitting ($4.27{\pm}0.56$) showed a significantly better sound quality ratings than the program fitting ($3.69{\pm}0.74$) (p=0.017). Conclusion The REM fitting showed better results in both subjective and objective measurements than the program fitting.

To identify the relationship between types of job classification (typical and atypical) and the levels of recognition of noise and the hearing threshold shift, a total of 457 workers in a cosmetic company were studied utilizing a questionnaire and the audiometric hearing test. The results were analyzed by factor analysis, t-test, and general linear model, as appropriate. The results showed that atypical workers had higher level of noise recognition but had lower levels of hearing ability, noise exposure, and the knowledge on hearing loss prevention, compared with those of typical workers. The high noise level group of typical workers showed higher threshold shift levels than that of atypical workers. Significant differences were found at 4 kHz for both ears and in right ear only for hearing threshold shift after adjusting age.

Most individuals with hearing impairment have difficulty in understanding speech in noisy situations. This study was conducted to investigate sentence recognition ability using the Korean Standard-Sentence Lists for Preschoolers (KS-SL-P2) in pre-school age children with cochlear implants and hearing aids. The subjects of this study were 10 pre-school age children with hearing aids, 12 pre-school age children with cochlear implants, and 10 pre-school age children with normal hearing. Three kinds of signal-to-noise (SNR) conditions (+10 dB, +5 dB, 0 dB) were applied. The results for all pre-school age children with cochlear implants and hearing aids presented a significant increase in the score for sentence recognition as SNR increased. The sentence recognition score in speech noise were obtained with the SNR +10 dB. Significant differences existed between groups in terms of their sentence recognition ability, with the cochlear implant group performing better than the hearing aid group. These findings suggest the presence of a sentence recognition test using speech noise is useful for evaluating pre-school age children's listening skill.

This study was designed to investigate the effects of neonatal hearing screening program (NHSP) information on parental satisfaction with the Parent Satisfaction Questionnaire with Neonatal Hearing Screening Program (PSQ-NHSP) by Mazlan et al. (2006). The PSQ-NHSP consisted of four aspects including: information, personnel in charge of the hearing test, appointment activity, and overall satisfaction in the neonatal hearing screening program. A total of 106 parents (50 in the experimental group and 56 in the control group) participated in this study in one general hospital and two delivery clinics. The fifty parents in the experimental group received information and counseling with educational materials before filling out the PSQ-NHSP, but the fifty-six parents in the control group did not receive any counseling or education materials before completing the PSQ-NHSP. The PSQ-NHSP demonstrated excellent internal consistency reliability (${\sigma}=0.914$). The results of the study were as follows. First, the overall satisfaction ($3.77{\pm}0.81$) and personnel in charge of hearing test ($3.52{\pm}0.79$) aspects showed higher rates of satisfaction than the appointment activity aspect ($3.51{\pm}0.80$) for total subjects. Second, the overall parental satisfaction rate of the experimental group ($4.15{\pm}0.50$) was significantly higher than that of the control group ($3.09{\pm}0.53$) in all items. Lastly, thirty-two participants (30%) made at least one comment in response to the open-set items. A total of 29 comments were related to satisfaction with participating in the NHSP and II comments were related to dissatisfaction. In conclusion, to improve parental satisfaction it is important to provide parents with education and information about the NHSP before the test. In addition, PSQ-NHSP was found to be a useful instrument for identifying the benefits and shortfalls of the NHSP.
