Stone Industry in our country is classified mainly in view of supply of raw materials ingredients, as follows: Stone-Quarrying Industry who develops the natural resources, Stone Processing Industry who processes the quarried raw ore into construction materials and stone-products, Stony Mountain-Aggregate Industry who supplies the elementary raw materials ingredients to construction section, respectively. Among them, while Stone Processing Industry sells its turnover around billion-Won level per annum per a company, most of other job sites are paltry, adopting less than 10 employees, and it is real state that their working environments are also very coarse. The Noise originated from processing-instrument which generates at such Stone Processing Industry is as so repeatedly reiterating Loud Noise that most of the spot workers are forcedly imposing such dangers as the severe unpleasant feeling and hearing impairments. On this viewpoint, this Research is now analyzing on the frequency characteristics with regard to the Noise that generated from various processing-instruments, and then based on this, in order to grasp the influence of the Loud Noise generating when process the stone materials, this study has ever evaluated it with PSIL and NR. It is considered that such data could be used as the valuable material for establishment of a comfortable working environment hereafter.

After the Industrialization of 1960s, while it has greatly contributed to the industrial development owing to acceleration of mechanization, but it is real situation that the countermeasure to noise damage generating at the loud noise workshop is scarcely made. Especially, the machine noise made at factory and workplace is so shocking and repeatedly reiterating terrible noise that most of the spot workers are forcedly imposing such dangers as the severe unpleasant feeling and hearing impairments. On such point of view, this research has attempted to extract the proper rating vocabulary in order for evaluation on machine noise made at the high noisy workshop, therefore it is considering that those extracted vocabularies could be utilized as the useful psycho-acoustic experiment for evaluation on machine noise, also for establishment of regulation standard in domestic high noisy workshop.

종래에는 공조덕트의 소음 감소를 위하여 주로 흡음재료를 사용하여 왔다. 그러나 이러한 흡음재료를 이용한 소음감소대책은 500HZ 이상의 고주파 영 역에서는 효과가 있으나 500HZ 이하의 저주파 영역에서는 효과가 적다. 이 러한 500HZ이하의 저주파 소음은 각종 구조물의 진동을 야기시켜 정밀작업 이 요구되는 작업환경을 파괴하고, 심지어는 구조물에 손상을 입힐수도 있 다. 또한 이러한 저주파 소음에 노출된 사람의 심리를 불안하게 하여 일의 효율을 떨어뜨릴 뿐만 아니라 청력장애를 일으키기도 한다. 또한 청정환경이 요구되는 곳에서의 소음감소를 위하여 흡음재료를 사용할 경우 흡음재료로 부터 떨어져 나오는 미세분에 의해 청정환경의 보존이 어려워진다. 이러한 흡음재료를 이용한 수동소음제어 대책의 단점을 해결하기 위하여 소음을 그 소음과 동일한 진폭을 갖으며 위상차가 180도인 인위적인 음파로 상쇠시키 는 능동소음제어대책의 개발이 요구되어 왔다. 본 논문은 덕트 또는 이와 유 사한 음향환경내에서의 적응필터기법(adaptive filtering technique)을 이용한 능동소음제어방법의 개발, 실제구현 및 성능평가에 관한 것으로서, 특히 다 수의 에러 마이크로폰과 다수의 소음제어용 스피커를 사용하여 제어계통의 가관측성(Observability)및 가제어성(Controllability)을 향상시켜 평면파로 전 달되는 소음의 감소를 증대시킬수 있을 뿐만 아니라 고차모드(Higher-order mode)로 전달되는 소음의 제어도 가능케하는 능동소음제어 방법에 관하여 논하였다.

This study as a cross survey study was conducted to provide basic data for more practical approach to nursing the aged, by analyzing the relationship of the loneliness, self-esteem and quality of life on the hearing disturbance aged. This study was based on the survey data from the 90 aged, who are over sity years old and resident in Seoul. In order to measure the general characteristics and subjective audition, Cantril's Ladder Scale Tool was used. For the loneliness, UCLA Loneliness Scale Tool (translated into Korean to suit the Korean environment by Kim's). In order to measure the self-esteem, Rosenberg's Self-esteem Measurement Tool (translated into Korean by Chun) was used. No's Quality of Life Measurement Tool was used to the measure the quality of life. The Data were collected by direct interviewing on the subjects for this study from August 10, 1999 to September 15, 1999. In accordance with each purpose of this study, appropriate analyzing methods such as Descriptive Statistics, T-test, and ANOVA were used in analyzing the collected data. Pearson correlation coefficient was used to test the relationship of the loneliness, self-esteem and quality of life on the hearing disturbance aged. The result of this study is as follows: 1) The average of the degrees of subjective audition was 7.22, The factors that cause the result were sex, religion, the perception of health, the married state. 2) The average of the degrees of loneliness was 55.18, The factor that cause the result was the perception of health. 3) The average of the degrees of self-esteem was 28.42, The factors that cause the result were the number of family, the number of children, the perception of health. 4) The average of the degrees of quality of life was 71.87 the factors that cause the result were age, education, the number of children, the perception of health. 5) Correlation of Loneliness, self-esteem and quality of life is the perception of loneliness showed significant negative correlation with self-esteem (r=-.466, p=.0001) and quality of life (r=-.450, p=.0001). As a result of analysis above: Because of the recognition change of the aged, it seems to them that the subjective audition scale on the hearing disturbance aged is measured by only 10-point ladder scale is inappropriate. Therefore, it is necessary that the physiologic-index can confirm more exactly should be applied to them. It is very important that the social-psychological factor that has influence on the aged should be the self-perception of health. Thus, proper development of nursing intervention should be required to process in the self-perception of health on the aged.

For children with hearing impairment, unlike the children without hearing impairment who can reconstruct their languages through the process of hearing and uttering, the inherent mechanism for language acquisition do not operate due to the loss of hearing ability. Therefore, to help hearing-impaired children develop their language ability, web-based language learning system should be constructed depending on the special qualities which the children possess in language learning process. When the system is being designed, it is necessary that words or expressions describing actions or situations be animated and that active situation-based language learning system be constructed to help them develop their power of observation. Moreover, the system needs to be developed through the use of alternative thinking strategy, antonyms, and contrastive words, and emphasis on facial expressions. This paper presents web-based language learning system which is suitable for hearing-impaired children in the way to reduce the grammatical errors they make and to improve their language learning.

The purpose of this study is to look at the way that speech-to-text (STT) services are used at present, and to explore measures to institutionalize such services for ease of communication for the hearing impaired. The results of this study show the following: 1) 17.8% of those surveyed had experience of using STT services, with younger individuals showing a higher rate of use; and 2) In terms of organizations providing STT services, social welfare organizations followed by civic groups (18.3%) and public organizations (18.3%). The following institutional measures are needed for STT services. First, STT services should be actively promoted as one of the reasonable conveniences defined in the 'Act on the Prohibition of Discrimination Against Disabled Persons, Remedy Against Infringement of Their Rights, etc.' Second, STT services should be additionally listed as one of the clauses of the 'Act on Welfare of Persons with Disabilities'. In particular, establishing a communication system for those with hearing impairments should serve as a catalyst for integration with sign language interpretation and welfare services. If STT services for face-to-face contacts can be improved or further enhanced using ICT, it will not only open the way for a new influx of disabled workers to join vocational rehabilitation, but also help to improve quality of life for the hearing impaired.

A person with defects and the lack of hearing, has very difficult problems to listen to the sound of conversation or environment, and these problems cause wrong directions in the linguistic sense and character. We designed and implemented an application to practice and correct pronunciation of a hearing-impaired person specially. This is made as a mobile app without the limitation of time and space, and this provides practices with the level of difficulty in learning of pronunciation, taking into consideration of remedial status in pronunciation. The hearing-impaired person can train the basic pronunciation and the word pronunciation. He or she can practice basic skills in pronunciation and check the record on the practice rate and the success rate. Also, the person can improve pronunciation by self-correction function using the front camera of a smart phone.
