  • The purpose of this study is to examine the effects of the parents listening guidance program, which allows the parents to understand their hearing impaired children and how to listen at home, on the communication skills of the hearing impaired children. The research subjects were 3 hearing impaired children who did not accompany with the intellectual, emotional and behabioral problems, and the listening guidance has been performed for their parents for 3 months through the listening guidance program. The changes in the communication skills in the hearing impaired children were observed comparing before and after the education. In the results, first, the receptive language skill of the hearing impaired children was improved after than before the parents listening guidance. Second, the expressive language skill of the hearing impaired children was improved after than before the parents listening guidance, too. Third, in the communication behavior of the hearing impaired children, the phonation and the speech production were increased together with the gesture after the parents listening guidance. In conclusion, it is deemed that the parents listening guidance program would have positive influence on the communication behavior of the hearing impaired children.

  • A study to get the data of normal stop consonants production as preliminary study for cleft palate patients was performed. Normal Korean native 21 speakers were pronounced $VCV(V=/a/,C=/P/,/{P^1}/,/P^h/,/t/,/{t^1}/,/{t^h}/,/k/,/{k^1}/,/{k^h}/)$ syllables with natural speech rate and intensity. With intrapharyngeal pressure waveforms by pressure sensor in oropharyngeal cavity, amplitude and time duration of intrapharyngeal pressure were analyzed, and with acoustic waveforms and spectrograms, closure duration and VOT were analyzed. As results, the highest amplitude of intrapharyngeal pressure showed in alveolars and heavily aspirated consonants. Velars and unaspirated consonants were higher than bilabials and slightly aspirated ones each, in intrapharyngeal pressure. Bilabilas, alveolars and velars showed similar rise time of intrapharyngeal pressure build-up, but in decay time and total duration time, bilabials were slightly shorter than alveolars and velars, with no statistic significance. In the aspects of tensity, unaspirated consonants showed the longest rise time, heavily aspirated, the second, and slightly aspirated consonants, the shortest, which were also seen in decay time and total duration time. In closure duration, slightly aspirated consonants had the shortest closure duration, and the heavily aspirated ones, the second, and unaspirated consonants showed the longest. In VOT, heavily aspirated consonants showed the longest, slightly aspirated ones, the second and unaspirated ones showed the shortest.

  • The term "phonosurgery," coined in the early 1960s, refers to surgical procedures that maintain, restore, or enhance the human voice. Phonosurgery includes phonomicrosurgery (endoscopic microsurgery of the vocal folds), laryngoplastic phonosurgery (open-neck surgery that restructures the cartilaginous framework of the larynx and the soft tissues), laryngeal injection (injection of medications as well as synthetic and organic biologic substances), and reinnervation of the larynx. Phonomicrosurgery is a means of maximally preserving the layered microstructure of the vocal fold, that is, the epithelium and lamina propria. The purpose of the surgery is usually to improve the vibratory characteristics of the layered microstructure of the vocal folds. Phonomicrosurgery has developed from convergence of microlaryngoscopic surgical technique theory and the mucosal wave theory of laryngeal sound production. Improvements in technology (i.e., laryngoscopes, handled instruments, and lasers), which in part arise from developments in more frequently performed minimally invasive surgical procedures, will probably facilitate the next generation of procedural innovations. The best methods of optimizing phonosurgical outcomes include making an accurate diagnosis, completing a comprehensive voice evaluation, providing sufficient preoperative therapy, carefully selecting patients to undergo phonomicrosurgical procedures, and requiring sufficient postoperative rest and therapy. Phonomicrosurgery will continue to evolve as a result of the interdependent collaboration of surgeons with voice scientists, speech pathologist, and other voice professionals.

  • It is widely known that the Japanese alveolar nasal (n) is affected by adjacent vowels in most positions, that is, the variants of the alveolar (n) occur conditionally. The Japanese (n) is palatalized under the influence of vowel (i) or palatal (j). In the articulation of (ni), for instance, the tip and sides of the tongue make wide contact with the palate. It is interesting to know how palatalization occurs and varies during the production in different contexts. In my presentation, the actual realization of the palatalized alveolar nasal in different contexts is examined and clarified by consider me the Electro-palatographic data and examining the articulatory feel ins and auditory impression. As a result, palatalized (equation omitted) occurs either word-initially or inter-vocalically. (equation omitted) in (equation omitted) and (equation omitted) has great palatality. When conditioned by (j), the (equation omitted) in (equation omitted), (equation omitted) and (equation omitted) has full palatality. In each sound the average number of contacted electrodes of the Electro-palatograph at maximum tongue-palate contact is 63 or 100% of the total. To summarize the experimental data, articulatory feel ins and auditory impression, it can be concluded that the (n) followed by or hemmed in (i), (j) is a palatalized nasal (equation omitted).

  • As a dental technician, the aim of the present study on maxillofacial prosthesis was to research its relation with dental technology and further development aspects by looking into its history, kinds, production materials and process. Dental technicians are to expect a great potential to work as maxillofacial prosthetist if having an interest in education of maxillofacial prosthesis field, and developing and operating the education process by expanding the range of dental technology. This article is to present overall history of maxillofacial prosthesis and some background information on the materials which have been used from the past. The maxillofacial field plays essential functions of mastication and speech, as well as performs appearance, which evokes good or bad feelings as an instant and instinctive response. The use of maxillofacial prostheses is not merely the replacement of a missing part of the face, resulted from injuries, but a rehabilitation process to help individuals come back to society. Rehabilitation includes both patient's physical and psychological recovery, such as self-esteem and selfconfidence. There has been a rapid development in application potentials of maxillofacial prosthesis technology which include implant, which can penetrate skin, and new materials. In order to produce maxillofacial prosthesis, general procedures of maxillofacial laboratory work should be understood first. Maxillofacial prosthesis and the dental prosthesis have many similarities in its academic perspective and originality. Maxillofacial prosthesis should be added into the curriculum for dental technology to achieve co-enhancement of the two fields.

  • It is widely hewn that the Japanese alveolar nasal [n] is affected by adjacent vowels in most positions, that is, the variants of the alveolar [n] occur conditionally. The Japanese [n] is palatalized under the influence of vowel [i] or palatal [j]. In the articulation of 'に', for instance, the tip and sides of the tongue make wide contact with the palate. It is interesting to know how palatalization occurs and varies during the production in different contexts. In my presentation the actual realization of the palatalized alveolar nasal in different contexts is examined and clarified by considering the Electro-palatographic data and examining the articulatory feeling and auditory impression. As a result, palatalized [${\eta}$] occurs either word-initially- or inter-vocalically. [${\eta}$] in [${\eta}$i] and 'いに'[$i{\eta}$] has great palatality. When conditioned by [j], the [${\eta}$] in 'にゃ'[${\eta}$ja], 'にょ'[${\eta}jo$] and 'にゅ'[${\eta}jw$] has full palatality. In each sound the average number of contacted electrodes of the Electro-palatograph at maximum tongue-palate contact is 63 or 100% of the total. To summarize the experimental data, articulatory feeling and auditory impression, it can be concluded that 'the [n] followed by or hemmed in [i], [j] is a palatalized nasal [${\eta}$].

  • Total laryngectomy has become an usual treatment for any advanced carcinoma of the laynx, but most patients who have undergone total laryngectomy have shown permanant disability in voice production. I compared the first three formant frequencies estimated from MRI to those measured directly from speech data of the T-E patients and the normal. It was to estimate the accuracy of MRI and to compare the vocal tract shape of the normal to T-E patients. The obtained results were as follows : 1. The middle sagittle section of the MRI represents vocal tract well during pnonation. The vocal tract shape of the T-E shunt patients are lack of pharyngeal space and superior space of the glottis. 2. The length of the normal subject's vocal tract is 17 cm. For the T-E shunt patients, the length from lip to shunt opening is 17.5 cm in case 1, and 18.5 cm in case 2. That of the true resonante chamber is 13 cm and 13.5 cm for each case respectively. 3. T-E shunt patients phonated strained voice. The intensity of the higher formant frequency decreased especially in /o/, /u/. 4. The vocal tract is shortened during the phonation by T-E shunt patients. In case of /e/ and /i/, front cavities are constricted while back cavities are shortened. 5. The pseudoglottis of the T-E shunt patients is located at $14{\sim}15\;cm$ below from lips.

  • Previous studies on the bilinguals' lexical selection have suggested some evidence in favor of language-specific hypothesis. The purpose of this study was to see whether Korean-English bilinguals' semantic systems of Korean and English are shared or separated between the two languages. In a series of picture-word interference tasks, participants were to name the pictures in Korean or in English with distractor words printed either in Korean or English. The distractor words were either semantically identical, related, unrelated to the picture, or nonexistant. The response time of naming was facilitated when distractor words were semantically identical for both same-(Naming pictures in English/korean with English/Korean distractor words) and different-language pairs(Naming pictures in English with Korean distractor words and vice versa). But this facilitation effect was stronger when naming was produced in their native language, which in this case was Korean. Also, inhibitory effect was shown when the picture and its distractor word were semantically related in both same- and different-language paired conditions. These results show that bilinguals'two lexicons compete to some extent when selecting the target word. In this viewpoint, it can be concluded that the lexicons of either languages may not be entirely but partly overlapping in bilinguals.

  • Reading disability (dyslexia) refers to an unexpected difficulty with reading for an individual who has the intelligence to be a much better reader. Dyslexia is most commonly caused by a difficulty in phonological processing (the appreciation of the individual sounds of spoken language), which affects the ability of an individual to speak, read, and spell. In this paper, I describe reading disabilities by focusing on their underlying neurobiological mechanisms. Neurobiological studies using functional brain imaging have uncovered the reading pathways, brain regions involved in reading, and neurobiological abnormalities of dyslexia. The reading pathway is in the order of visual analysis, letter recognition, word recognition, meaning (semantics), phonological processing, and speech production. According to functional neuroimaging studies, the important areas of the brain related to reading include the inferior frontal cortex (Broca's area), the midtemporal lobe region, the inferior parieto-temporal area, and the left occipitotemporal region (visual word form area). Interventions for dyslexia can affect reading ability by causing changes in brain function and structure. An accurate diagnosis and timely specialized intervention are important in children with dyslexia. In cases in which national infant development screening tests have been conducted, as in Korea, if language developmental delay and early predictors of dyslexia are detected, careful observation of the progression to dyslexia and early intervention should be made.
