Objectives: Although language sample analysis is essential for language evaluation, it is not widely conducted due to time constraints and difficulties in analysis. This study was conducted to evaluate the Korean-Automatic Language System (K-ALAS), which was developed to support language sample analysis. Methods: 50 language samples of young children aged 2 to 6 were analyzed by K-ALAS and a language analysis expert. The percentage agreement of the analysis results between K-ALAS and the expert on Eojeol, words, and morpheme, which are the basic units of language measurement, were calculated, and t-test and Pearson correlation analysis were conducted on the main language measures (MLUe, MLUw, MLUm, NTJ, NTE, NDJ, NDE, NTW, NDW, TTR) measured by K-ALAS and the expert. Results: The percentage agreement of the eogeol, word, and morpheme analysis between K-ALAS and the expert, was found to be very high at 97.87-99.88%, and the t-test results showed that there was no significant difference between all language measures measured by K-ALAS and the expert, and the result of correlation analysis was also very high with r = .972-1.000. Conclusion: This study confirmed that K-ALAS analyze language samples and measures the main language measures very accurately. We discussed the implications of clinical use of K-ALAS in relation to language diagnosis and intervention.

Objectives: Connective endings play an important role not only in producing complex sentences but also in logically expressing thoughts. The purpose of this study was to examine the development of the use of connective endings in the spontaneous language of children aged 2-6. Methods: A total of 250 children aged 2 to 6 participated in the study, in groups of 50 by age group. Spontaneous language samples were collected between the examiner and the children via a semi-structured conversation procedure in which the topic of conversation and the examiner’s conversational behavior were controlled. The total number of connective endings, number of connective endings by subcategory and by subtype were measured by extracting 50 utterances from each child’s language sample. Results: (1) The total number of connective endings (CE) and the numbers of the three CE categories increased significantly according to age and the significant differences were observed before and after the age of 4. (2) In the subtypes of CE, auxiliary and closing connective endings were the most frequently used in all age groups, and closing connective endings significantly increased from 2 to 4 years old. However, there was no significant difference in the use of auxiliary connective endings according to age because they were used frequently from the age of 2. (3) The total number of CE (39.4%), and the subordinate category (40.9%) among the three CE categories; cause (31.3%), purpose (9.6%), choice (5.5%), list (2.4%) among the subtypes of CE explained age. Conclusion: The study confirmed that the developmental pattern of the use of connective endings in spontaneous language of the children aged 2-6. We discussed the academic and clinical implication of the result and suggest the needs of the follow-up study.
The Implementation of Flipped Learning in the EFL Classroom: Outcomes and Attitudes
이윤경 언어과학회 2018 언어과학연구 Vol.0 No.87
The aim of the study is to examine the effects of flipped learning on Korean college learners’ study of English. A total of 79 intermediate level students participated in the study. Of the participants, 40 were in the flipped class whereas 39 were in the non-flipped class. Data were gathered from students’ achievement, their responses to a survey, a Likert-scale questionnaire, and an interview about their attitude to the flipped model. The findings revealed that students’ achievements in the flipped class were statistically significant in their final grade, but in the subsection, only listening and vocabulary scores indicated statistical significance. Regarding students' attitude to flipped learning, half the students demonstrated a positive attitude to the approach whereas the other half showed some reservation about it. Based on the findings of this study, practical suggestions and pedagogical implications for the current flipped model were discussed.
노인장기요양서비스의 지역별 공급 형평성 시계열 변화 분석

본 연구는 노인장기요양서비스의 지역별 공급 분포를 집중지수와 집중곡선을 통해 지역별 공급의 형평성을 평가하고, 노인장기요양 보험제도 전후의 서비스 공급의 형평성의 변화를 분석하였다. 분석결과 노인장기요양보험제도 도입이후 지역별 형평성은 향상되었으나, 노인요양시설은 인구밀도가 낮은 도시지역이 농어촌과 중소도시에 비해 적게 공급되고 있으며, 재가시설인 방문요양서비스와 주야간보호서비스는 인구밀도가 높은 도시지역의 공급이 높은 것으로 나타났다. 따라서 향후 노인장기요양서비스의 공급 정책은 지역간 접근 형평성을 보장하기 위해 지역특성과 서비스 특성을 고려한 정책수립이 수행되어야 할 것이다.
