The purpose of this study is to develop sign language interpreting content in the medical setting that facilitates Deaf people's access to medical services in situations where professional and accurate medical sign language interpreting is insufficient. To achieve the purpose of this study, we conducted a literature review, individual interviews for Deaf people, on-site requirement surveys of sign language interpreters and sign language experts, and medical and sign language expert consultations. Based on this, we developed sign language interpreting content such as main care contextual scenarios, basic medical terms, and medical term descriptions. Through this study, we developed medical sign language content considering the situation and medical importance of Deaf people to promote expertise in the medial sign language area and developed a responsive website of sign language medical dictionary that effectively and efficiently delivers information to Deaf people and sign language interpreters; we realized the need and importance of sign language translation for Deaf people to be the main bodies.

This study examined the difference between the deaf and hearing adolescents of experiencing emotions and the intensity levels of expressing them. Three different video clips were used to induce pleasure, anger, and sadness. While watching the clips, facial expressions of the participants were recorded. The experienced emotions were measured by a self-report method, and the third person rated participants' expressed emotions based upon the recorded facial images. Two groups (deaf and hearing) were compared if those two groups shared the same experienced emotions, and whether the ratings scored by the third person corresponded with the self-rated scores. There was no significant difference in experienced emotion and its intensity level. However, hearing adolescents showed more intensive responses of pleasure than they reported, while deaf adolescents showed less intensive expressions of happiness than they reported themselves. Thus, hearing people might not be able to detect and fully comprehend how the deaf feel in general circumstances. This further indicates that the deaf adolescents cannot get enough supports from the hearing people when they express their feelings, and consequently, have a possibility of causing misunderstandings, conflicts, or even a break in relationships.

The purpose of this study was firstly to provide fundamental data on the activation for the IP-based video phone for the special consumer related to the physically handicapped; secondly to inform empirical data for the consumer public policy in the information technology market, specially for the deaf people. The results of study showed that consumer needs extend to not only simple voice communication for general consumers but also special demands for both the handicapped and the elderly. This study also indicated that VoIP's characteristics of technology would be easily applied to the TRS or VRS which can be adapted to the special consumer market so that VoIP service would be optimal technology for the special consumers like the deaf. In order to successfully implement TRS & VRS business, the paper proposed as follows; 1) the provision of VoIP service enable to satisfying consumers in special market such as the deaf market and the elderly market, 2) the necessity of supporting policy by the related law, and 3) the construction of the system inducing interests from the market participants.

It has long been known that high-frequency sensorineural hearing loss (HFHL) can contribute to difficulty in speech understanding by elderly listeners. This study evaluated the relative contribution of HFHL and age to speech understanding. Subjects included adult middle-aged and old groups with normal hearing or with limited HFHL. The Hearing-in-Noise-Test (HINT) was used to measure speech perception performance in quiet and in noise. The middle-aged groups showed significant effects of HFHL for speech intelligibility in quiet and in noise, but the old groups showed the difference in quiet only due to high frequency hearing. The results suggest that HFHL may affect speech intelligibility differently with age and therefore hearing aid selection needs to take into account the influence of age.

The purpose of this study is to improve guidelines for public library services to deaf community in Korea. For this study, literature review, case study and survey were performed. Based upon the results, the mandatory and optional elements were suggested within the framework of "Standards and Guidelines for Library Services for the Disabled" developed by National Library Support Center for the Disabled in Korea in 2009. Based upon these elements, public libraries should modify and supplement the guidelines reflecting the local circumstances. Eventually, this guideline will help librarians to provide professional and effective library services to deaf people.

This study aims to develop communication devices and interfaces to address the communication needs of the hearing impaired. Through three FGI (Focused Group Interview)s with deaf persons and sign-language interpreters, we studied the communication methods, devices, and needs of the deaf. On the basis of our analysis, we propose a communication framework to improve their means of communication with normal or other deaf persons. We have designed a communication system that is based on the proposed framework: this system suggests functions for remote sign-language interpretation services for conversations in close-range and over the phone. Details are presented regarding the design of interfaces for video calls, text messages, and digital memos, addressing the conversation patterns of the deaf. The system includes hardware form factors for video phones that facilitate sign language conversations and also mitigate other auditory problems in daily life, such as problems with door bells. The design concept has been verified through a test with six deaf users.

Human-computer interaction is a discipline concerned with the design, evaluation, and implementation of interactive systems for human use. In this paper we suggest designing a smart deaf emergency application based on Human-Computer Interaction (HCI) principles whereas nowadays everything around us is becoming smart, People already have smartphones, smartwatches, smart cars, smart houses, and many other technologies that offer a wide range of useful options. So, a smart mobile application using Text Telephone or TeleTYpe technology (TTY) has been proposed to help people with deafness or impaired hearing to communicate and seek help in emergencies. Deaf people find it difficult to communicate with people, especially in emergency status. It is stipulated that deaf people In all societies must have equal rights to use emergency services as other people. With the proposed application the deafness or impaired hearing can request help with one touch, and the location will be determined, also the user status will be sent to the emergency services through the application, making it easier to reach them and provide them with assistance. The application contains several classifications and emergency status (traffic, police, road safety, ambulance, fire fighting). The expected results from this design are interactive, experiential, efficient, and comprehensive features of human-computer interactive technology which may achieve user satisfaction.

This paper analyzes the vocal tract area estimation algorithm used as a part of a speech analysis program to help deaf children correct their pronunciations by comparing their vocal tract shape with normal children's. Assuming that a vocal tract is a concatenation of cylinder tubes with a different cross section, we compute the relative vocal tract area of each tube using the reflection coefficients obtained from linear predictive coding. Then, we obtain the absolute vocal tract area by computing the height of lip opening with a formula modified for children's speech. Using the speech data for five Korean vowels (/a/, /e/, /i/, /o/, and /u/), we investigate the effects of the sampling frequency, frame size, and model order on the estimated vocal tract shape. We compare the vocal tract shapes obtained from deaf and normal children's speech.
