본 연구는 부모의 사회.경제적 지위가 아동의 음운 인식 능력 발달에 미치는 영향을 조사하는 것이 목적이다. 본 연구에서는 P 시의 소득 수준이 상이한 3지역을 선정하여, 각 지역 초등학교 1학년에 재학중인 아동들을 대상으로 본 연구자들이 자작한 음운 인식 검사 도구를 사용하여, 음운 인식 능력을 측정하였다. 검사는 개별적으로 일대일로 이루어졌으며 각과제의 점수를 백분율로 환산하여 통계 분석에 사용하였다. 집단을 독립 변인으로 하고 각음운 인식 검사 결과를 종속 변인으로 하여 일원 변량 분석 방법과 Scheffe 다중 분석을 실시한 결과는 다음과 같다. 부모의 사회.경제적 지위가 아동의 음운 인식 능력에 많은 영향을 미쳤다. scheffe 사후 검증 분석 결과 부모의 사회.경제적 지위가 상위에 해당하는 아동집단과 중산층 집단 간에, 중산층 집단과 부모의 사회.경제적 지위가 하위인 아동의 집단간, 그리고 상위인 집단과 하위인 아동 집단간에 음운 인식 능력에 큰 차이가 있었다. 본 연구의 시사점은 언어와 관련된 연구와 검사 도구 개발에서는 대상을 표집할 때 아동의 부모의 사회.경제적 지위가 고려되어 표집되어야 만이 표집의 대표성이 확보가 된다는 점이다. There are several factors that could account for children``s phonological awareness ability. Those factors such as phonological units(i.e., syllable, onset-rime, body-coda, phoneme), type of phonological awareness(i.e., isolation, blending, segmentation, deletion, substitution, addition), type of response(i.e., accuracy, rate), characteristic of norm(i.e., age, sex, location of residence, existence of disability, language ability) and parents`` status should be taken into account when it is being developed.. Thus, the effect of thses factors on phonological awareness ability of children need to be examined. The purpose of this study is to investigate the influence of parent``s social economic status on phonological awareness ability in children when phonological awareness assessment is being developed. Students were sampled from three different school in terms of economic status of residence, such as from low class neighborhood, middle class neighborhood, high class neighborhood. Phonological awareness assessment designed by the current researchers were conducted to each student on one to one basis. Results were following. Children``s phonological awareness ability was different according to their parent``s social economical status. The kids from poor neighborhood have poor phonological awareness ability while the children from rich environment have higher phonological awareness ability. This means that parents`` social economical status can account for some of individual variation of phonological awareness ability. Consequently, developer should consider this fact when he or she develop phonological awareness assessment.

This study compared the effectiveness of Two reading intervention programs, the PASS Reading Enhancement Program(PREP) and repeated reading program, on subsequent reading skills of children with reading disabilities. Thirty second grade children with reading disabilities were randomly assigned to a 5 week phonological awareness, Phonological aware ness activity program All children received 7 hours of one to one instruction in two 40 minute sessions per week for 5 weeks. The two programs compared with the repeated reading porgram which is one of the traditional intervention program to improve reading skills. The two intervention programs are different from each other in the primary domain of reading instruction and the approach to intervention (auditory versus visual stimulus). Results indicated that children in both phonological awareness program and PREP achieved significant gains in word reading skills in comparison to children in the control group which is repeated reading program group. However, phonological awareness program turned out to be more effective than the PASS Reading Enhancement Program on word identification skills. The phonological awareness program group scored higher than the PREP group in reading. Therefore, these findings confirm the phonological awareness deficit hypothesis in reading disabilities. In sum, phonological awareness is an important for early reading. Key Words : phonological awareness

In shipyard, plate forming is widely used to form the ship hull plate in various shapes. Line heating method by using a flame torch is one of the major shipbuilding processes carried out by skilled workers. Since the forming characteristics depend upon their experiences in manual forming, there are much variations between products and difficulties in communication between engineers and workers. Hence, it needs to develop an automatic forming system which can not only reduce the working time and rework costs but also improve the working environment and hull forming productivity. One of the final goals of plate forming automation is to form a target shape from the initial plate automatically. For automated plate forming, it is required to determine where and how to heat on the plate. To realize this procedure, the inverse problem should be first solved and the effect of curvature shape formed at the heating path should be investigated. In this study, the inverse problem was solved by geometrical approach using the relationship between bending angle and radius of curvature of the curved shape. In addition, experiments of two-dimensional plate forming were performed with the distance-based method considering the curved bending with curvature. The result of the formed shape agreed considerably well with the target shape.

본 연구의 목적은 학령기 인공와우이식 아동의 구어능력을 어휘 이해 및 표현과 구문으로 나누어서 생활연령에 근거한 구어능력과 청각연령에 근거한 구어능력을 알아보고, 구어능력에 대한 수술연령, 수술전 청각수행력, 인공와우 사용기간, 생활연령, 현재의 청각수행력의 관련성을 분석하여 학령기 인공와우이식 아동의 청각-언어 재활에 대한 기초적 자료를 제공하고, 언어 중재에 대한 시사점을 제시하고자 하는 것이다. 이를 위해 만 5세 이전에 인공와우이식을 받고 초등학교에 재학 중인 인공와우이식 아동 79명을 대상으로 어휘력 검사와 구문의미 이해력검사를 시행하여 생활연령에 근거한 표준점수와 청각연령에 근거한 표준점수를 산출하였고, 언어 영역간 점수 차이를 비교하였다. 인공와우이식 아동의 구어능력에 대한 수술연령, 수술전 청각수행력, 인공와우 사용기간, 생활연령, 말소리 지각력의 관련성을 알아보기 위해서 상관분석과 중다회귀분석을 시행하였다. 분석 결과, 인공와우이식 아동의 생활연령에 근거한 구어능력은 또래 건청 아동에 비해서 매우 낮은 것으로 나타났으며, 특히 형태구문능력에서 큰 결함이 있었다. 청각연령에 근거한 구어능력을 분석한 결과 어휘발달 속도에서 청각연령이 같은 건청 아동보다 빠른 발달을 보였고, 표준점수는 건청 아동의 정상범주에 해당하였다. 관련변인을 분석한 결과, 수술연령과 말소리 지각력이 유의한 영향을 미치는 것으로 나타났다. The purpose of this study were to investigate the oral language abilities of school-aged children with cochlear implants in terms of vocabulary and morpho-syntactic aspects, and to analyze the effects of child-related factors and speech perception on language abilities in these children. The subjects of this study were 79 children with cochlear implants who received the cochlear implantation under age of five and used oral communication, and 114 CA matched normal hearing children. Language abilities were evaluated using the REVT and KOSECT, and were calculated standard scores with reference to both chronological age and hearing age. The effects of child-related factors and speech perception on language abilities were analyzed using correlational analysis and multiple regression. Participants showed oral language delay in standard scores derived from CA, but not in standard scores derived from HA. Among three aspects of language, children with CIs had more difficulties in morpho-syntactics than in receptive and expressive vocabulary. The results of multiple regression revealed speech perception and age at implantation affected oral language abilities of school aged children with CIs. These results showed that continuous and intensive auditory-language education, especially focusing on grammar, is required for school years, and early implantation is helpful for reducing the language delay before implantation.

The purpose of this study was to investigate the working memory of children with Specific Language Impairment and normal language and to examine the relation between these children's working memory capacity and their language competence. Ten children with SLI and ten chronological age-matched (age range = 3;6 to 6;6) children with typical language development participated in this study. Children are usually identified by researchers as having a specific language impairment when there are no obvious contributing factors, such as hearing impairment, neurological impairment, or mental retardation, that can account for below-age language ability. And normal nonverbal IQ scores are necessary for diagnosis of SLI.The ‘Nonword Repetition test’ and the ‘Digit Span test’ was used to test the Phonological loop and ‘Reading Span test’ was used to test the Central Executor.The conclusion from the results and discussion are as follows:First, when we examined working memory capacity between children with SLI and normal language controlling their phonological awareness and their language age, no significant between-group differences were found.Accordingly poorer performance of children with SLI on working memory test reflect their poor language competence and poor phonological awareness.

The purpose of this study was to investigate the effects of Phonological Awareness Training on brain activation profiles of a child with RD. A child with RD was tested on two reading tasks (words vs. pseudo-words) and re-tested on the same tasks after 24 sessions of Phonological Awareness Training. The child's brain profiles were then compared.The results measured after Phonological Awareness Training are as follows: (1) In word reading tasks, the test subject showed increased activation of left inferior frontal (pars opercularis), middle temporal, inferior frontal (pars triangularis), postcental, and right cerebellum crus 2. (2) In pseudo-word reading tasks, the test subject showed increased activation of left middle temporal, anterior cingulum, middle frontal (pars orbitalis), middle occipital, and right middle occipital.These results suggest that phonological awareness training might affect the development of neural systems in key reading areas.

The purpose of this study was to compare phonological awareness ability depending on level on childrens language competence. The examines were composed of 15 gifted children, 15 normal children and 15 children with language delays who are first grade in elementary school.   The result obtained in this study were as follows:   (1) Relationship was found between language ability and phonological awareness ability in children. This means that phonological awareness ability play an important role in development of language.   (2) The total score of phonological awareness tasks of the children with language delays were significantly lower than normal children and language gifted.   This means that children with high language ability performed better on all types of task while children with normal language development and language delay showed different pattern in performance on the test. They performed differently on each test in terms of task level and task type. Children from both performed better on phonological deletion and blending task than substitution and discrimination task.
