The current Navigation System for the Visually Impaired Person has a short and limited communication distance and can't receive enough information from Visually Impaired Person to assist directly. In addition, because the path is dangerous and incomplete for the Visually Impaired Person, moving with White Stick is still inconvenient and dangerous. To solve this problem we implement communication that can send and receive video, voice, location information between the Visually Impaired Person's Smart Portable Navigation System Development and assistant's PC.

연구개는 그 주위조직과 더불어 생리적 기능에 있어 음성, 연하, 및 호흡 등에 중요한 역할을 한다. 종양등의 이유로 인한 연구개의 외과적 절제는 그 해부학적 크기와 모양의 영구적인 변화로 인해 여러기능의 상실을 초래한다. 이에 따른 결함은 과도한 비음, 연하중 음식물이나 유동물의 비관으로의 누출 등을 들 수 있다. 연구개와 그 주위조직의 생리적인 기능의 숙지 및 이를 응용한 보철물(Palatopharyngeal Obturator)의 적절한 제작은 이러한 기능적 결함을 수복하는데 이용되어진다. 본 증례에서는 종양으로 인해 연구개를 절제한 환자의 보철적 수복에 있어, 구강내 온도에 따라 그 형상이 변화하는 인상재를 이용하여, 측-후 인두벽의 운동을 기능적으로 인기하는 방법을 이용하였다. 이러한 방법으로 제작된 보철물은 종양으로 인한 연구개의 절제 후 생리적인 기능의 장애를, 올바른 Palatopharyngeal 폐쇠를 유도함으로써 음질의 향상, 연하등의 기능을 회복시키는데 큰 도움이 될 수 있음을 보여준다.

It is possible to implement an optical character recognition system using a high-resolution camera mounted on smart phones in the modern society. Further, characters extracted from the implemented application is possible to provide the voice service for the visually impaired person by using TTS. But, it is difficult for the visually impaired person to properly shoot the objects that character information are included, because it is very hard to accurately understand the current state of the object. In this paper, we propose a method of inducing an appropriate shooting for the visually impaired persons by using a smartphone gyro sensor. As a result of simulation using the implemented program, we were able to see that it is possible to recognize the more character from the same object using the proposed method.

The purpose of this study is to suggest the visual teaching method for the English vowel pronunciation, especially for the hearing-impaired who mostly rely on the visual aids, based on the SVM technique. By extracting phonetic features using the SVM technique from the sounds that are hard to hear by ear, the lip shapes for each vowel were refined. The lip shape refinement for vowels is advantageous in that language learners can easily see the movement of articulators by eye, and it is helpful for learning and teaching English vowels for the hearing-impaired.

The DAISY, an international digital talking book standard, has been established to help reading-disabled people read books normally. As many societies' interests in reading-disabled people are arising, reading environment for them is also getting improved by supplying alternative books. In the digital world, however, there is still lack of e-book playing software for them. In this paper, we design and partially implement an android smartphone e-book viewer. By analyzing the features and relations of DAISY3 files, we can find several important design points to properly implement DAISY3 viewer. We are sure, when using our results, that various DAISY3-compliant e-book viewers can be implemented easily and quickly.

무선인터넷 서비스는 이동통신 사업자들에게 강력한 추가수익원으로 떠오르고 있으며, 활성화를 위하여 장기적이고 효율적인 정책대안 수립이 절실한 시점이다. 본 연구에서는 무선인터넷 산업의 현실을 올바로 파악하고자 하는 노력의 일환으로 무선인터넷 사용자들에 대하여 설문조사를 수행하였으며, 그 결과를 무선인터넷 이용환경, 이용실태, 평가 등 세 부분으로 나누어 서술하였다. 무선인터넷은 엔터테인먼트용 콘텐츠의 이용도가 높아 여가생활에 도움을 주고 있지만, 실생활에는 아직 큰 도움이 되지 못한다는 평가를 얻었다. 그리고 통신요금에 대한 불만이 가장 높은 것으로 나타나, 무선인터넷 서비스 확산에 큰 장애요인으로 떠올랐다. 그리고 정액제에 대한 높은 선호를 확인함으로써 통신요금 체계도 무선인터넷 확산에 걸림돌이 되고 있는 것으로 판단하였다. 한편 본 조사에서는 전자우편의 이용횟수, 무선인터넷 및 음성통화의 하루평균 이용시간, 통신요금 및 정보이용료 지출액 등에서 여성의 활용도가 활발한 것으로 나타나 이동통신 서비스 확산에서 여성의 역할이 부각되었다. 결론적으로 우리나라는 무선인터넷 서비스 확산을 위한 하드웨어적인 준비는 거의 완료되었으나 요금수준 및 체계, 통신품질, 콘텐츠 등 소프트웨어 측면에서의 준비는 다소 미비한 것으로 판단되며, 해당 분야에 대한 집중적인 연구와 투자가 필요한 시점으로 생각된다.

This research intended to identify empirical recommendations for designing the DAISY service interface and used a case-based method. The case of this research was LG Digital Talking Book Library(http://voice.lg.or.kr) of LG Sangnam Library. A group of experts evaluated the current DAISY interface serviced by the web. After evaluation, major recommendations were suggested and these recommendations were used to develop the new DAISY Interface. Major recommendations were consideration of the reading flow of the screen-reader program, prevention of perception as an error about the time delay, development of web-based software, support for convenient functions and prevention of shortcut key overlap and so on.

본 논문에서는 청각장애인에게 자막방송을 제공하기 위하여 오디오 콘텐츠에 등장하는 음향 사건을 분류하는 기법을 제안한다. 제안된 기법은 복수의 잔차 신경망(ResNet)을 연결하는 연쇄잔차(concatenated residual) 신경망 구조를 갖는다. 신경망의 입력 특징을 위해 음성의 멜-주파수 켑스트럼 벡터를 다수의 프레임으로 결합하여 형성한 2 차원 이미지와 전체 프레임에 대한 멜-주파수 켑스트럼 벡터들로부터 얻은 1 차원의 통계 특징벡터를 얻는다. 각각의 입력은 2 차원 잔차 신경망과 1 차원 잔차 신경망으로 모델링되고, 두 개의 잔차 신경망을 연쇄연결(concatenation)하는 구조를 가진 연쇄잔차 신경망으로 구성된다. 성능평가를 위해 수집된 데이터셋으로부터 6-fold 교차검증을 통해 평가한 결과, 85.48%의 분류 정확도를 얻을 수 있었다.

In a society undergoing rapid change, modern individuals are facing various stresses, and there's a noticeable increase in mental health treatments for children as well. For the psychological well-being of children, it's crucial to swiftly discern their emotional states. However, this proves challenging as young children often articulate their emotions using limited vocabulary. This paper aims to categorize children's psychological states into four emotions: depression, anxiety, loneliness, and aggression. We propose a method for constructing an emotion dictionary tailored for children based on assessments from child psychology experts.

Unlike other common forms of speech disorder, such as phonological disorder or dysphonia, stuttering has not been studied within the context of music therapy. Most cases of stuttering display no difficulty in singing, and fluency within the musical structure does not translate to fluency in speech. Hence, musical approach has been generally considered to be ineffective to the treatment of stuttering. However, the fundamentals of music therapy assume its extensive application in treating variety of speech disorders, including the case of stuttering. Presented in this paper are the case studies designed to validate the efficacy of music therapy as a remedy for stuttering. This study enrolled 6 children with stuttering and conducted 20 individual sessions over a period of 10 weeks. The sessions focused on the Melodic Intonation Therapy, Reinforcement of speech rhythm, song writing and singing. Musical elements were structured to enhance the verbal expression and rhythmic senses, as well as to facilitate the initiation of verbal communication. The result is as follows. First, it was noticed that the disfluency had been decreased in before and after of the music therapy in every child although the result was somewhat different depending the child. The overall result of the investigation shows the significant difference statistically. And categorically speaking, the significant difference was checked in the frequency of the stuttering. In the steps of the session, the increase and decrease was happened repeatedly, and then after it was decreased little by little. Secondly, the Communication Attitude was decreased in before and after of the music therapy, and also there was significant difference statistically. although the avoidance behavior was decreased in before and after of the music therapy, the increase and the decrease was repeated irregularly in the steps of session. All the results described above shows that music therapy gives positive effect to decrease in disfluency of stuttering child and also to develop the Communication Attitude. And new possibility and effectiveness can be proposed in the musical approach to the stuttering.
