말소리의 생성 및 전달에서 화자의 청각적 피드백은 말소리 발달에 중요한 부분을 차지한다(고도흥 외, 2000). 그러나 청각장애 아동의 경우, 청각적인 피드백이 부족하여 말소리 발달과 언어발달에서 지체를 보이게 된다. 특히 이러한 말소리 발달은 아동의 말명료도에 큰 영향을 미치게 되고, 국내외 여러 학자들은 청각장애 아동의 말 산출에 대한 연구를 활발하게 하고 있다. 그러나 현재 국내의 연구 중 이중모음에 대한 연구는 거의 없는 실정이다. 국내의 청각장애 성인이나 아동을 대상으로 한 연구들은 대부분 연구자의 지각적이고 주관적인 입장에서 이루어지고 있다. 좀더 객관적인 연구 자료는 임상적인 목적뿐만 아니라 말소리 발달의 연구에서 필요하다. 따라서 이 연구는 청각장애 아동의 이중모음의 특징을 음향음성학적인 방법으로 객관적으로 분석하여 그 자료를 제시하고, 건청 아동과의 비교를 통해 임상적인 자료를 제시하고자 한다.

The purposes of this study were : (1) to find out subjective well-being structural model of people with disabilities, (2) to compare the female's subjective well-being structural model with male's. Based on previous researches related to subjective well-being of non-disabled, I applied a integrative model of bottom-up and top-down theories to subjective well-being of people with disabilities. Data were gathered from 497 persons with disabilities(253 males and 244 females) in Korea. This research shows that the female's level of life satisfaction is not different to male's. In female group, the objective life conditions(the level of education, family income, and to have jobs or not) and self esteems are important variables in subjective well-being structural equation model. In male group, on the other side, recognition about social support level is important variable. Various theoretical and practical implications for social work practice were discussed.

DCS(Digital Cross-connect System)를 이용한 다이나믹 자체 치유 알로리즘들은 주로 대상을 하나의 링크 장애에 대해서 완전 복구될 수 있는 예비 용량을 갖는 망을 대상으로 복구 시간을 줄이는 방향들이 제시되어 왔으나, 이러한 고장난 망의 복구를 위한 자체 치유 복구 알고리즘의 효율성은 이중 장애나 노드 장애에 적용 되었을 때의 복구율을 가지고 평가가 된다. 본 논문에서는 단일 링크(single link) 장애뿐만 아니라 이중 링크(double link) 장애에 대해서도 망의 복구 허용시간 내에서 복구율을 높이는 새로운 망복루 알로리즘을 제안한다. 이를 위해서 망의 복구 허용 시간 내에, 전체적인 예비 용량을 고려하여 선택된 복구 경로의 각 링크의 부하를 균등하게 하는 복구 방법을 적용한다. 또한 제안된 알고리즘의 시뮬레이션 결가를 기본의 복구 방법과 비교 분석한다.

To increase network survivability and to guarantee reliable services in MPLS networks, when failures occur either at any link or node of a working path, traffics on the failed path should be switched to other restoration paths. In this paper, we propose a path restoration method using duplication of working paths for link failure and its associated failure detection method, which utilizes OAM cells when all the duplicated links or nodes of the path failed. We analyze the performance of the proposed restoration method and show that especially the method is very efficient to restore high priority traffics. Also, through simulation we prove that the proposed restoration method is superior in performance to several existing methods suggested so far.

The aim of this study is to prepare basic data that can be used for evaluation and intervention by investigating the characteristics of diphthongs produced by children with speech sound disorders. To confirm this, two groups of 10 children each, with and without speech sound disorders were asked to imitate the meaningless two-syllable 'diphthongs + da'. The slope of F1 and F2, amount of change of formant, and duration of glide were analyzed by Praat (version 6.1.16). As a result, the difference between the two groups was found in the slope of F1 of /ju/. Children with speech sound disorders had smaller changes in formants and shorter duration time values compared to normal children, and there were statistically significant differences. The amount of change in formant in the glide was found in F1 of /ju, jɛ/, F2 of /jɑ, jɛ/, and there were significant differences in the duration of glide in /ju, jɛ/. The results of this study showed that the range of articulation of diphthongs in children with speech sound disorders is relatively smaller than that of normal children, thus the time it takes to articulate was reduced. These results suggest that the range of articulation and acoustic analysis should be further investigated for evaluation and intervention regarding diphthongs of children with speech sound disorders.

변성발성장애는 변성기의 시기를 지났음에도 불구하고 적절한 음도저하를 습득하지 못함으로써 야기되는 음성장애의 한 가지로, 이런 환자들에 대해서는 제3형 갑상연골성형술을 통한 수술적 처치나 음성치료로 그 문제를 해결할 수 있다. 본 논문에서는 이중 음성치료적인 측면에 초점을 맞추어, 음성치료에 의한 변성발성장애 치료의 효율성에 대해 고찰해 보고자 한다. (중략)

오늘날 웹은 급속도로 확산되어 교육에 있어서 필수적인 존재로 강력한 힘을 발휘하게 되었다. 사이버 교육 환경의 시대를 맞이하여 웹을 이용한 학습 활동의 비중은 점점 더 증가되었지만 대다수의 웹기반 교수 (Web-based Instruction : WBI)학습 사이트들이 비장애인 중심의 사용자 인터페이스로 설계됨에 따라 청각 장애인을 학습 공간에서 격리 시키고 학습 능력을 저하시키는 이중 장애를 발생시키고 있다. 따라서 본 논문에서는 최근 청각 장애인의 교육방법으로 대두되고 있는 이중언어-이중문화 접근법 (Bilingual Method : 2Bi 이론)을 활용하여 청각 장애인의 WBI 학습 능력을 신장시킬 수 있는 사용자 인터페이스를 설계하였다. 본 사용자 인터페이스의 특징은 다음과 같다. 첫째, 청각 장애인의 웹접근성을 고려한 인터페이스를 설계하여 청각 장애 학습자가 보다 쉽게 학습 공간에 접근하게 하였다. 둘째, 청각 장애인의 장애 정도 및 학습 성취 정도에 따라 3단계 사용자 인터페이스를 제공하여 수준별 학습이 가능하다. 셋째, 순차적 반복 학습이 가능하여 청각 장애인의 학습 능력뿐 아니라 의사소통 기능 향상에도 긍정적인 영향을 제공한다.

This study aimed at empirically analysing the double discrimination on the elderly with disabilities due to both age and disabilities in the labor market. To achieve this research goal, real employment probabilities and hourly wages of the elderly disabled(below "ED") were compared with those of the young disabled(below "YD") and those of the elderly non-disabled(below "END") to calculate empirical differentials between ED's and YD's, and ED's and END's. The differential decompositions between groups were applied by the Oaxaca(1973). The study results were as followings. First, the real gaps of the employment probabilities between ED and YD only appeared at the regular jobs and the gaps due to the characteristics between ED and YD were bigger than those due to the age discrimination. Second, on the contrary, the gaps of the hourly wages were caused by age discrimination more than characteristics between YD and ED. Third, it was not true that the elderly with disabilities take double discriminations in the labor market. It is therefore required to give the additional incentives to ED workers with government subsidies of employment promotion for the disabled provided. Second, it is proposed that the integrations the employment policies for the disabled with those for the aged because the disability as dependent valuable didn't have statistically significant effects on the employment probabilities and the hourly wage levels.

This study was conducted to qualitatively analyze the selected research through a systematic review to find out application method, outcome measures, and intervention effects of dual task. We searched for published studies from January 2010 to December 2019. Electrical database were PubMed and ProQuest. Search terms were 'dual task' OR 'multi modal' AND 'mild cognitive impairment' OR 'dementia' OR 'Alzheimer's disease'AND 'intervention' OR 'rehabilitation. There were 8 studies selected finally. The dual task was applied not as a single intervention but as a combined intervention with other exercises. The contents of dual task were consisted of motor and cognitive tasks to be independent each other. The outcome measures included general cognitive function such as MMSE and CERAD, executive function, and memory. Additionally the dual task cost was also used to identify the direct improvement of the dual task. This study could provide informations of dual task application on elderly with cognitive impairment.

Object : This study aimed to identify the factor structure of Korean-Child Behavior Checklist 1.5-5 Dysregulation Profile (K-CBCL 1.5-5 DP) in infants and toddlers with mental disorders and verify differences in K-CBCL 1.5-5 DP among the diagnosis groups. Methods : The participants were 265 mothers of infants and toddlers with mental disorders who completed K-CBCL 1.5-5 DP. The data was analyzed using AMOS 25.0 and SPSS 25.0. Results : First, the bifactor model was the most suitable for the factor structure of the K-CBCL 1.5-5 DP. Second, there were significant differences among the diagnosis groups, such as communication disorders, pervasive developmental disorders, emotional disorders, and developmental delays. It was confirmed that the pervasive developmental disorder and emotional disorder groups showed significantly higher dysregulation compared with the communication disorder group. Conclusion : This study confirmed that infants and toddlers had dysregulation problems. Using the bifactor model, the multidimensional nature of the K-CBCL 1.5-5 DP was assessed. It was also meaningful that dysregulation could contribute to onset and deepening of symptoms of pervasive developmental disorders and emotional disorders in infancy.
