파닉스 중심 한글읽기프로그램이 지적장애학생의 한글읽기에 미치는 효과에 관한 사례연구
정가희,이대식 한국지적장애교육학회 2019 지적장애연구 Vol.21 No.1
This study set out to investigate the effects of a phonics-based Korean (Hanguel) reading program reflecting Hanguel’s characteristics on the Hanguel reading and reading behavior of students with intellectual disabilities. Also, it coped with the reactions of their parents and classroom teachers based on the effectiveness of the program. This study was conducted in two stages. four students with intellectual disabilities that were in the first or second grade of elementary school were instructed in phonics-based Hanguel reading for about 25 minutes per session for a total of 65 sessions. The students took an alternate form evaluation to measure the understanding of the curriculum content every week. This curriculum based measurement especially aimed to check improvements of the participants in Hanguel reading levels before and after intervention and compare with the control group. As a result of the study, the phonics-based Hanguel reading program showed positive effects on the Hanguel reading skills of students with intellectual disabilities. Of the four subjects, three reached a certain level of Hanguel reading. In addition, the reading behaviors of students with intellectual disabilities cleary improved. Based on these results, the students' parents and homeroom teachers had high expectations for the possibilities of the growth for their Hanguel reading behaviors. In conclusion, it was effective to apply the phonics-based instruction when teaching Hanguel reading to students with intellectual disabilities. This study is significant in that it is presented with suggestions for follow-up research and discussion on the direction how phonics-based Hanguel reading program can be applied at the school site. 본 연구에서는 한글의 특성을 반영한 파닉스 중심 한글읽기프로그램을 적용하였을 때 지적장애학생의 한글읽기능력 및 읽기행동 그리고 그에 대한 학부모 및 교사의 반응에 어떠한 영향을 미치는지 알아보고자 하였다. 본 연구는 1∼2단계로 이뤄졌으며 1∼2학년 지적장애학생 4명을 대상으로 회기 당 20∼30분, 총 65회기 동안 한글을 지도하였다. 또한 주 1회 동형평가를 제작하여 한글수준평가를 실시하고 종료 후에 유지 여부를 확인하였으며 대조군과 중재 전-후 읽기수준변화를 비교하였다. 연구 결과, 연구대상자 중 대부분이 한글해득수준에 도달하였으며 지적장애학생의 읽기행동이 향상되었다. 또한 학부모 및 통합학급 담임교사가 지적장애학생의 가능성을 믿고, 기대감을 갖게 되었다. 이러한 결과를 통해 지적장애학생에게 파닉스 중심 지도방법을 적용할 때 한글의 특성을 반영하는 것이 효과적이었음을 알 수 있었다. 본 연구에서는 학교 현장에서 실제로 지적장애학생에게 파닉스 중심 한글읽기프로그램을 적용할 수 있는 방향에 대한 논의와 후속연구를 위한 제언이 제시되었다.

The purpose of this study was to examine the effects of Data-Based Individualized(DBI) Hangul phonics instruction has on reading achievement(Hangul reading, alphabet knowledge and decoding). Three elementary students with intellectual disabilities in grades 3 to 5 participated in this study furthermore a multi-probe design across participants was used to investigate the effects of both the intervention and maintenance. A researcher provided a DBI hangul phonics program to the student participants 3 times per week, 30 minutes per day a total of 20 to 38 sessions was delivered to the students. Researcher-developed hangul CBM measures were used consistently across baseline, intervention, and maintenance phases in addition standardized tests on alphabet knowledge and decoding were used before and after the intervention. The results of this study showed that the level of hangul reading of the students was improved at the intervention phase compared to its level at the baseline phase, and the effects were maintained after the phase was completed. In addition, post-test scores on alphabet knowledge and decoding were higher than the pre-test scores. However, the degree of improvement of decoding was varied across individual students. These results imply the positive effects of using DBI hangul phonics instruction to enhance reading achievement of elementary school students with intellectual disabilities. Based on the findings-discussion, limitations and suggestions for future research were suggested. 본 연구의 목적은 데이터기반개별화(DBI)를 적용한 한글파닉스 교수가 초등학교 지적장애 학생의 읽기 성취도(한글읽기, 자모지식과 해독)에 미치는 효과를 확인하는 데 있다. 초등학교 3~5학년 지적장애학생 3명이 참여하였으며, 대상자간 중다간헐기초선 설계를 적용하여 중재와 유지 효과를 확인하였다. 연구자는 연구 참여 학생들에게 DBI 한글파닉스 프로그램을 주 3회, 1회에 30분씩 20~38회 제공하였다. 중재의 효과를 확인하기 위해 연구진이 개발한 한글읽기 CBM 검사를 기초선, 중재, 유지 구간에서 지속적으로 적용하였으며, 표준화검사를 사용하여 자모지식과 해독 영역에 대한 사전-사후 검사를 실시하였다. 연구 결과 기초선 구간에 비하여 중재 구간에서 대상 학생들의 한글읽기 수준이 향상하였으며, 그 효과가 유지되는 것으로 나타났다. 또한 자모지식과 해독의 사후검사 결과가 사전검사 결과보다 높은 것으로 나타났다. 다만 해독의 향상 정도는 개별 학생에 따라 차이가 있었다. 이러한 연구 결과는 본 연구에서 적용한 DBI 한글파닉스 교수가 초등학교 지적장애학생의 읽기성취도를 향상하는 데 긍정적인 영향을 미침을 시사한다. 이러한 연구 결과를 바탕으로 논의와 연구의 제한점 및 후속연구를 위한 제언을 제시하였다.

Due to increasing demand for aesthetics, zirconia crowns have become a popular choice for treating primary molars. However, there is limited literature available comparing the survival rates of zirconia crowns with those of other restorative materials. The objective of this study was to compare the 36-month survival rates of zirconia crowns and stainless steel crowns for proximal caries, as well as to analyze failure types associated with each crown type. Electronic medical records and radiographs of 1,061 primary molars from 498 patients treated with 2 types of prefabricated crowns at Chosun University Dental Hospital and 2 private dental clinics between 2017 and 2019 were collected and analyzed. The survival rate of zirconia crowns was found to be lower compared to that of stainless steel crowns. Regarding the groups without pulp treatment, the survival rate of stainless steel crowns was significantly higher than that of zirconia crowns. However, in the groups that received pulp therapy, no significant difference in the survival rates was observed between the two preformed crowns. Notably, abnormal root resorption or periapical lesions were identified as the primary cause of restorative failure in stainless steel crowns, whereas loss of restoration was the predominant cause in zirconia crowns. This study holds valuable implications for clinicians when selecting preformed crowns for primary molars.

Ameloblastic fibro-odontoma (AFO) is a rare odontogenic tumor, which occurs in young children before the age of 20 years. Radiologically, it is a well-defined radiolucent lesion containing radiopaque masses. Histopathologically, AFO is composed of odontogenic epithelium in a primitive-appearing connective tissue and hard tissue consisting of enamel and dentin. It is commonly found in the mandibular posterior region. AFO may be asymptomatic and is often associated with delayed tooth eruption. As it shows similar characteristics clinically and radiologically to odontoma, differential diagnosis through histopathological examination is important. Treatment of AFO is conservative enucleation, and teeth enclosed or associated with the lesion may require extraction. In this report, 2 young patients who visited our clinic with a chief complaint of delayed eruption were diagnosed as AFO with radiological and histopathological examination. After the surgery, the healing status was found to be favorable, and no evidence of recurrence was observed.
