Inclusion of hearing impaired students in general schools is the current tendency in deaf education today. The goal of inclusion is to promote the academic and social inclusion of hearing impaired students, where academic inclusion focuses on higher academic achievement and class participation level. However, some studies have shown that hearing impaired students attending general schools mostly experience feelings of isolation, rejection and loneliness, and encounter identity development problems. This study reviews the research on the inclusion of hearing impaired students in general schools, as well as the perceptions of their parents, teachers on their academic and social inclusion. A further aim of this study is to explore the supporting services, teachers's attitude, career guidance service and effective collaborative partnership among teachers for hearing impaired students. This study concludes with suggesting the community of knowledge as integrative supporting strategy for inclusion.

Objectives The purpose of this study is to estimate the differences in sensory responses(Visual, Auditory, Olfactory and Taste responses) among Sasang Constitution. Methods We recruited 90 healthy subjects who were divided into three groups(30 Soeumin, 30 Soyangin, 30 Taeeumin). First, subjects saw the photo of 'the dress' and were asked to answer three questions about 'the dress'. And we evaluated auditory function by a Tone Deaf Test(TDT) and Adaptive Pitch Test(APT). Olfactory function was evaluated by using Korean Version of Sniffing' Sticks(KVSS) Test II and Taste function was evaluated by using taste strips. Results and Conclusion 1. Overall, 60% of subjects described 'the dress' as blue/black(B/B); 23.3% as white/gold(W/G); 16.7% as something else, and the difference in the proportion of reporting color of 'the dress' was statistically significant. 2. As the result of analysis of taste strips according to Sasang constitution, there was significant difference that Soyangin scored higher than Soeumin in sweet taste score. 3. As the results of analysis of auditory function test(TDT, APT) and that of olfactory function test(KVSS Test II) according to Sasang constitution, there were no statistically significant differences.

A bacterial strain No. KY-126, which produced extracellular cyclodextrin glycosyltransferase(CGTase), was isolated from soil and identified as Bacillus stearothermophilus KY-126. The enzyme was purified by the treatments of ammonium sulfate precipitation, DEAF-Sephadex, Sephadex G-100 column chromatography. The optimal pH and temperature for the enzyme activity were pH 5.5 and $65^{\circ}C$, respectively. And the enzyme was stable at pH values from 6.0 to 11.0 at $55^{\circ}C$ for 30 min and stable up to $60^{\circ}C$ for 30 min.. The enzyme was inhibited by $HgCl_{2}$. The molecular weight of the enzyme was estimated to be 67,000 by using SDS-PAGE. The maximum conversion from starch to cyclodextrin (CD) by CGTase was 43% and obtained at 6 hr reaction and the ratio of ${\alpha}-,\;{\beta}-,\;{\gamma}-$, CD production at this time was 2.9 : 2.1 : 1.0.

In this paper, we propose TV caption-based KSL(Korean Sign Language) generation system. Through TV caption decoder, this caption signal is transmitted to PC. Next, caption signal is segmented into meaning units by morphological analyzer in considering specific characteristics of Korean sign language. Finally, 3D KSL generation system represents the transformed morphological information by 3D visual graphics. Specifically, we propose a morphological analyzer with many pre-processing techniques for real-time capability. Our developed system is applied to real TV caption program. Through usage of the deaf, we conclude that our system is sufficiently usable compared to conventional TV caption program.

Hand shape is one of important elements in Korean Sign Language (KSL), which is a communication method for the deaf. To express sign motion in a virtual reality environment based on OpenGL, we need an editor which can insert and modify sign motion data. However, it is very difficult that people, who lack knowledge of sign 1anguage, exactly edit and express hand shape using the existing editors. We also need a program to efficiently construct and store the hand shape data because the number of data is very large in a sign word dictionary. In this paper we developed a KSL hand shape editor to easily construct and edit hand shape by a graphical user interface (GUI), and to store it in a database. Hand shape codes are used in a sign word editor to synthesize sign motion and decreases total amount of KSL data.

This study surveyed people with hearing impairments and speech defect living in an area of Gyeonggi-do using a self-administered questionnaire and interviewed them with a deaf interpreter's help during the period from January 21 to February 14, 2009 in order to investigate their oral health management attitude according to their general characteristics. The difference between males and females was statistically significant. The results of this study were as follows. 1. As to the number of times of tooth brushing according to gender, 62.5% of males and 34.2% of females brushed their teeth 2 times, and 25.0% and 35.4% 3 times. 2. As to experiences in scaling according to Academic qualification, those with high academic qualification had scaling more regularly 3. As to tooth brushing methods according to cohabitant, the rolling method was most common regardless of cohabitant. As to the number of times of tooth brushing according to residence type, 41.9% of those living with their parents brushed their teeth 3 times, and 69.2% of those living alone and 47.5% of married ones 2 times. 4. With regard to how to access oral hygiene management education, 81.1% of elementary school graduates used multimedia materials and sign language explanation and captions, 48.6% of middle school graduates used multimedia materials and sign language explanation and 14.3% multimedia materials and captions, 50.0% of high school graduates used multimedia materials and sign language explanation and 17.3% multimedia materials and captions. The parish for the buccal cavity hygiene managements of the hearing impairments speech defect and Development of an educational program are needed.

The deaf can not recognize useful sound informations such as alarm, doorbell, siren, car horn, and phone ring etc., because they have the hearing impairment. To solve this problems, portable hearing assistive devices which have suitable environment sound recognition methods are needed. In this paper, the DTW algorithm for sound recognition system with new active slope weighting constraint method was proposed. The environment sound recognition methods consist of three processes. First process is extraction of start point and end point using frequency and amplitude of sound. Second process is extraction of features and third process is classification of features for given segments. As a result of the experiment, the recognition rate of the proposed method is over 90%. And, the recognition rate of the proposed method increased about 20% than the conventional algorithm. Therefore if there are developed portable assistive devices which use developed method to recognize environment sound for hearing-impaired persons, they could be more convenient in life.

Background and Objectives The objective of this study was to examine the effect of early cochlear implantation (CI) performed in infants less than 12 months of age. Subjects and Method Twenty-five children who received their first CI before 12 months of age were included in this study (infant group). The speech perception and language outcomes of these children were compared with those of 14 children who received their first CI between 13 and 24 months of age (older group). All children received sequential bilateral CI with the inter-stage interval of less than 2 years. Speech perception was measured using Categories of Auditory Performance, monosyllabic word test and sentence test, and language ability was measured using Sequenced Language Scale for Infants, Preschool Receptive-Expressive Language Scale, or Receptive & Expressive Vocavulary Test, depending on the age at the time of testing. Results There were no significant differences in speech perception abilities between the infant group and the older group. The mean expressive language score of infant group was higher than that of the older group, but the difference was not statistically significant. However, the receptive language score of infant group was significantly higher than that of the older group. Conclusion Children who received CI before 12 months of age achieved better receptive language ability than those who received it after 12 months of age. Thus CI should be performed as early as before 12 months of age to achieve better language ability.

This study identified the experiences that the disabled actually feel in the library space in the face of growing social demands for spatial functions in public libraries. This study also tried to determine the requirements for the space that disabled wanted. For the research, 15 subjects were selected for each of the five people who were blind, deaf, and handicapped with experience using the library and individual in-depth interviews were conducted for the research. The study found that the experience of the disabled in the library space differed by type of disability and generally more negative experiences were found than positive ones. Misperception about the disabled of library staff and the non-disabled were having a significant impact on the disabled's negative experience for library space. There were a wide variety of opinions on the requirements for library space and there were generally negative perceptions about the current level of library space for the Integrated library service space.

Hearing - impaired children who have difficulty hearing and hearing go through pronunciation training. The purpose of this study is to provide the pronunciation training system based on digital contents that can be used for repeated hearing training while maintaining interest in hearing - impaired children. For this purpose, we conducted an interview survey for users and experts. Based on the results, we developed a digital content based pronunciation training system. Finally, to verify the effect of the digital service implemented, the user test was conducted for the hearing - impaired children. As a result of the interview, repeated training and interest factors were found to be essential factors affecting pronunciation training. In implementing digital services, we have used fairy tales and a variety of interactive elements to derive children's interests and designed a user flow that can train multiple words and sentences for effective repetition training. As a result of the test, this digital content was evaluated positively.
