김건구,김기쁨,나원도,한우재 대한청각학회 2016 Journal of Audiology & Otology Vol.20 No.2

This brief communication introduced a systematic way to find a professional audiology clinic developed for patients and professionals by the American Academy of Audiology, American Speech-Language-Hearing Association, and Healthy Hearing. Patients can access each organization’s website to find professionals and/or clinics based on criteria such as location, hours, special areas, types of service, reviews and rating by previous patients, and kinds of insurance accepted. Such a system may protect the patients from information overload, guarantee accurate information, and help them find themselves professional audiologists who can assist them. We expect professional organizations to adopt this system as soon as possible and link hearing-impaired patients with professional audiologists in Korea.

어음명료지수의 측정과 적용

Speech Intelligibility Index (SII) is a model that predicts speech intelligibility based on a person’s hearing thresholds and audible speech cues in given frequency bands. The SII is able to predict how loss of audibility due to hearing loss affects intelligibility of speech. Thus, the SII has been applied clinically in evaluation and fitting for hearing aids to quantify how much audibility is compensated by amplification. Although the SII known as Articulation Index was first introduced during the 20th century, calculation methods and aspects of the SII have been continually refined and developed for clinical use. This article provides (1) a brief history of the SII, (2) a view of components and calculation methods of the SII, (3) a review of applications for clinical use, and (4) a discussion of limitations and aspects that need to be considered for clinical applications in future.

Current nations in the world can be divided into the kind of nations which pursue the ideology of democracy and those which follow the socialism. Yet, both kinds of nations are commonly trying to increase a variety of exchanges and cooperations with each other beyond the barriers of the system and ideology. This trend is accelerating after the collapse of the Soviet Union. In other words, they haven't yet escaped from the boundaries of the system-competition in a way, while they have been making efforts to overcome the limitations of the system and ideology under the awareness that it is more important to solve the realistic problems. The field of physical education cannot be independent from this worldwide trend, and the looser the political tension becomes, the more lively the sports exchange becomes. So is in the case of South and North Korea. Since 1970's both nations have been trying to make contact and have many kinds of conferences with each other, among which sports conferences were most frequent. Gradually, they could achieve visible results, which made the hearts of people leap. For it is no exaggeration to say that we are opening the horizon of new awareness through the concrete experiences such as single soccer team, and single table tennis team of South and North Korea. And yet, when we look back on many kinds of experiences of sports exchange, though there might be a principle agreement on the major premise of South and North cooperation, there were sometimes some inexplicable misunderstandings between the two nations. Therefore, it is absolutely necessary to understand exactly the societies and the true picture of the physical education in North Korea. The purpose of this research is to encourage the whole awareness in the physical education in North Korea. To have a correct recognition of the physical education in North Korea, there should be a systematic understanding of it through documents, followed by the research on the actual condition of it through observation. However, we all know well the fact that it is almost impossible to research on the actual state of the closed societies of North Korea through observation, and so, for the present the document study method is considered to be the best way. Thus, this paper have adopted the document study method and tried to analize the subject strictly, while there still remain the limitations of research on the actual conditions. Results from a few preceding studies on North Korean physical education system and materials published in North Korea and Japan suggest some points about North Korean school, social and national defense physical education system and sports facilities. In North Korea, physical acitivities are encouraged as one of political revolutionary projects or means of enhancing national prestige, rather than as ways to improve the health of its people or to make use of leisure. Regarding physical education ideology, North Koreans stress on constructing communistic system, and their physical education policy is directly related to their policy to enhance productivity Political purpose precedes mutual understanding and friendship in their international sports exchange policy. Combat exercise events prevail in their athletic competitions. In their physical education system, individual originality and the opinions of subsystem are ignored because subsystems are operated only by the orders of central system. In schools, combat exercise activities are the main activities of school physical activities to fortify national defense and to construct communistic system However, it is quite noticeable that Korean traditional games are included in their curriculum. In North Korea, People's School and kindergarten teachers are trained in Teachers' College for 3 years, and high school teachers in Teachers' University for 4 years, and their roles as teachers are mainly to instil revolutionism into their students. Social physical activities are enforced to improve national defense and productivity, and mass physical activities which contribute to encouraging the loyalty to the People's Party are stressed. People's Physical Fitness Test is mandatory to all citizens, and mass physical exercise and mass run are performed on political events and memorial days. Mass meetings are called on large scales to enhance the unity and collectivity of the people. All citizens as well as soldiers are subject to national defense physical activities, which consists of land, sea and air activities including 14 mass national defense physical activities and 24 practical national defense activities. It is noticeable that these activities are semimilitary training. The overall review of the North Korean physical activities shows that there are big differences between North Korea and South Korea in their organization and ideology. In the upcoming reunification of North Korea and South Korea, South Korea must play a leading role in straightening distorted North Korean physical education policy and many further studies are to be made on this matter. The difference as in physical education policies and objectives between North Korea and South Korea could be overcome through continual sports exchange, and eventually our steady efforts and true sportsmanship could be the first step toward the reunification of Korea.

Purpose: This study was to determine effects of three stimulus frequencies on tympanometry and to compare with Distortion Produtct Otoacoustic Emission (DPOAE) for regular and special school-age children. Methods: A total number of 182 school-age children, 152 recruited from regular elementary school and 30 from special school, participated. All participants were evaluated by tympanogram and DPOAE. Tympanograms were tested by 226, 678, and 1,000 Hz and analyzed with static compliance (SC) and earcanal volume (EV). Results: Depending on three stimulus frequencies, SCs and EVs were 0.49, 1.45, and 1.26 ml and 0.92, 2.98, 4.52 cm3 in regular school-age group and 0.56, 1.58, 1.29 ml and 0.98, 3.0, 4.48 cm3 in special school-age group. There were statistical significant differences among three frequencies but no difference between regular and special school-age groups for both SCs and EVs (p < 0.05). The pass and fail rate of DPOAE was 87.2% and 12.8% for regular school-age group and 57.6% and 42.4% for special school-age group, showing a statistical significant difference between groups (p < 0.05). Agreement rate between tympanograms and DPOAE results was the highest in 678 Hz. Conclusion: While there was no difference in middle ear status between groups, DPOAE results referred that the inner ear status could be poor for the special school-age group. Therefore, more interests of hearing status should be aroused to the special school-age children. Additionally, the 678 Hz seems to be more useful for screening school-age children. Further, more data with pure tone examination be supplemented for the certain conclusion.

Purpose: Although many previous studies related to sentence recognition of the hearing-impaired elderly have found their poor performance under various distracting listening conditions, there is still a lack of information for their error type in the sentence. The purpose of present study was to analyze a prominent error type among nine parts of speech in various levels of noise and fast speech conditions for the hearing-impaired elderly. Methods: Seven old listeners with moderate sensorineural hearing loss participated. For estimating their sentence recognition, Korean Speech Perception in Noise was applied for four signal-to-noise ratios (no noise, +6, +3, 0 dB) and four time alteration conditions (±30%, ±15%), while being presented at the most comfortable level to each participant. Total percent error and substitution error patterns of the sentence recognition were analyzed as a function of conditions. Results: The percent error of sentence recognition was increased as either noise level increased or speech rate was faster. Among the parts of speech, noun substitution error pattern showed the highest number for all participants regardless levels of noise and time alteration. Interestingly, the noun substitution error pattern was outstood in quiet and 15% time compression. Conclusion: Results of the present study suggest that aural rehabilitation of the hearing-impaired elderly may focus on reducing and correcting the noun substitution error to improve their sentence recognition.

This study investigated the differential muscular firing patterns of the shoulder muscles in patients with full-thickness rotator cuff tear. Eleven patients with unilateral rotator cuff tear were recruited. During isokinetic exercises, the muscular activities of upper trapezius, serratus anterior and lateral deltoid were recorded by surface EMG. Subjects performed isokinetic shoulder abduction of 60°/sec, and 180°/sec. The mean EMG amplitude of root mean square (RMS) was calculated to a percentage of maximal activity for each muscle. In the rotator cuff tear sides, the muscular activities of lateral deltoid in abduction were increased in 180°/sec compared to 60°/sec. And the EMG activities of upper trapezius and serratus anterior in the lesion side were significantly decreased compared to sound side in abduction of 180°/sec. But, in the case of lateral deltoid, the EMG activities were not different between sound and lesion sides in abduction of 180°/sec.
