The present study examined multicultural family children's articulation accuracy and phonological process using Assessment of Phonology and Articulation for Children(APAC), and compared them with normally developing children. The subjects of this study were 24 multicultural family children between ages 3 years, 6 months and 3 years, 11 months. The multicultural family children's articulation accuracy was significantly lower than the normally developing children's. In case of the normally developing children, phonological processes the multicultural family children showed were observed at a younger age and did not appear at the age of the children participating in this study. The Japanese multicultural family children and the non Japanese multicultural family children showed different rate of the changes. This result shows that articulation development in the multicultural family children may be different among them according to the classification and that the children's error patterns are related to their mothers' native language. The results of this study are proposed to be applicable to articulation assessment and treatment.

This study was designed to investigate the treatment, generalization, and maintenance effects of vocal relaxation treatment on compensatory articulation(i.e., glottalization of plosive sound) of three children with cleft palate. Multiple baseline design was applied to evaluate treatment, generalization, and maintenance effects. The targeted phonemes were ph/, th/, /t/ which Were frequently substituted by glottal stop sounds. The main component of the treatment program was vocal relaxation using humming and aspiration sound /h/. The following conclusions were deduced from the results: (1) the treatment program for compensatory articulation was effective in facilitating correct production of targeted phoneme and eliminating glottalization for all subjects, (2) the treatment effects on articulation accuracy were generalized to untreated phonemes (/c/, /c$c^{h}$/) for 2 subjects, (3) the treatment effects on decrease of glottalization were generalized to untreated phonemes for all subjects, and (4) the treatment effects were maintained for all subjects for 2 weeks after treatment was terminated.

본 연구는 경직형 뇌성마비 아동 30명을 대상으로 출생직후 섭식문제를 해결하기 위해 사용되는 비위관이 이후 아동의 섭식발달에 어떠한 영향을 주는지 살펴보았다. 2015년 7월 1일부터 8월 30일까지 뇌성마비 아동을 대상으로 조음능력을 평가하고 주양육자를 통한 섭식능력에 대한 설문조사를 실시하였다. 또한 섭식능력이 조음능력에 미치는 영향에 대해 살펴보았다. 수집된 자료는 SPSS 20.0을 사용하여 분석하였다. 연구결과 비위관의 사용여부는 조음정확도에 유의미한 차이를 보였다. 또한 섭식능력을 평가하는 문항 중 유동식 섭취가능여부, 섭식을 위한 특별한 방법과 도구사용여부, 깨물어 씹기 가능여부는 이후 조음정확도와 관련이 있는 것으로 나타났다. 본 연구 결과 초기 섭식능력의 일부 영역은 이후 조음능력에 영향을 미치는 것으로 보이며 예방적 차원의 접근과 조기개입이 적극적으로 이루어져야 할 것으로 생각된다.

This study was designed to evaluate the phonological characteristics in profound hearing-impaired children. 10 males and 10 females participated in this study and all were prelingually hearing impaired. 7 children were educated at deaf school and 13 children at general elementary school with private clinic. Their hearing levels were more than 95dB HL and did not appear any wave by ABR. The results can be summarized as following: The articulation accuracy of hearing impaired children was 54.19% and most distinguished phonological patterns of the hearing impaired children were alveolarization and stop assimilation. The accurate articulation phonation was significantly different from education system between deaf school and general school. The error articulation degrees in profound hearing impaired children at general school seemed meaningfully smaller than those in hearing impaired children at deaf school.

A multimedia Version of ${\ulcorner}Lee-Kim test of Korean Articulation{\lrcorner}$ "Lee-Kim Test of Korean Articulation" consisting of picture test, Sentence test, user's manual and notation, analysis sheets was published in 1990 to serve as a standard tool for testing and analysing the articulation errors of normal and abnormal speakers. It has been found, however that, the picture and sentences test using the printed version of Lee-Kim test of Korean Articulation revealed several limitations, in i, e, a) inefficiency in inducing desirable response from the informants b) lack of concentration and interest on the part of informants c) no consistent way of providing the informant with a clue in case the informant is unfamiliar with the word represented by the picture or the sentence. d) no reliable means for the speech-language pathologist to analyze and evaluate the informant's speech in relation to the standard pronunciation A multimedia version of Lee-Kim Korean articulation Test which features picture and word as well as recorded voice has been developed with a view to eliminating the limitation mentioned above and facilitating the articulation test-with ease and accuracy.

PURPOSE. This in vitro study was conducted to investigate the accuracy of intraoral scanner (IOS) for recording maximal intercuspal position (MIP) and border positions of the mandible. MATERIALS AND METHODS. Maxillary and mandibular master casts were articulated in MIP, protrusive, and lateral interocclusal position sequentially on a semi-adjustable articulator. For each articulation relation, sites of occlusal contacts (SOCs) and sites of clearance (SCs) were identified on the master casts with articulating paper (reference sites). IOS was used to take full arch scans and nine virtual interocclusal records (VIRs) for virtual articulation of models. Virtual SOCs and SCs were detected with 3D processing software and compared to those identified with the articulating paper. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated for each articulation relation. RESULTS. For MIP, IOS showed adequate sensitivity and NPV of 100%, and specificity and a PPV of 99%. For protrusive position, the IOS showed a sensitivity and a NPV of 100%, a high PPV of 86%, and a specificity of 83%. For lateral positions, the specificity and the PPV were high (93% and 79%, respectively), but the sensitivity and the NPV were below the clinically acceptable limits (28% and 56%, respectively). CONCLUSION. IOS displayed clinically acceptable accuracy for recording MIP and protrusive border mandibular position. However, IOS had less accuracy for lateral border mandibular position.

With the fourth industrial revolution, digitization is accelerating in all healthcare areas. In the field of dentistry, active discussions on digital dental technologies are ongoing, with increasing interest from clinicians daily. Thus far, accuracy and efficiency have primarily been emphasized in digital dentistry, and interest in occlusion has been relatively low. This is because digital dentistry has been predominantly used to restore small numbers of teeth rather than extensive prosthetic reconstruction. However, in the future, most dental treatments will undergo a digital transformation that will require the application of digital technology to more extensive prosthetic rehabilitation, for which discussion of occlusion is essential. In extensive prosthetic reconstruction, occlusion and articulation involve determining the position of the dental arch in relation to the reference plane of the skull or the long axis of the face and the position of the transverse horizontal axis. It also includes determining an occlusal surface with a shape that allows the mandible to move in an eccentric path and masticate most efficiently without any occlusal interference. To better understand how digitization will impact dentistry, this review article summarizes and discusses occlusion and articulation using digital dental technologies. This discussion is divided into several aspects, including facial scan, virtual articulation, augmented reality, and virtual reality.

본 연구에서는 한국어 비음의 조음위치 변별을 위한 지표로서 모음 음향 특성의 활용 가능성을 타진하였다. 비음에 인접한 /ㅏ/ 모음 시료를 대용량 한국어 자연발화 말소리 자료에서 추출하여 모음 구간의 25%, 50%, 75% 시점에서 음향 매개변수를 측정하였다. 이 스펙트럼 및 지속시간 변수를 이용하여 판별분석을 수행하고 이를 바탕으로 선행 또는 후행 비자음의 조음위치 분류정확도를 추정하였다. 또한 조음위치 공조음(coarticulation)의 관점에서 순행적 공조음과 역행적 공조음의 영향을 확인하기 위하여 측정 대상 모음에 비음이 선행하는 경우와 후행하는 경우로 나누어 비교하였다. 분석 결과, 전후 비자음의 조음위치 분류정확도는 약 50%-60%로 나타났다. 모음의 음향 매개변수 측정값만으로 비음의 조음위치를 예측·분류하기에는 어려움이 있으나, 공조음 정도가 가장 약할 것으로 예상되는 모음 정중 구간에서 측정된 음향 변수만으로도 위와 같은 정확도를 얻었다는 점에서 비음 구간의 분석결과와 함께 모음 측정치를 활용함으로써 비음 조음위치 인식률 향상에 기여할 수 있을 것으로 기대한다. 한편 측정 대상 모음에 선행 또는 후행하는 비음 조건 간에 비교하였을 때, 후행 비음 조음위치의 분류정확도가 더 높게 나타났다는 점에서 역행적 조음위치 공조음의 영향이 더 클 가능성이 확인되었다.
