The purpose of this study was to construct colloquial text measurement formulas that can be utilized in Korean writing evaluations, to draw up a list of colloquial grammar and vocabulary and analyze the frequency of the appearance of conforming text corpus in both spoken and written language. Logistic regression analysis was carried out on the frequency analysis results, and the derived regression equations were used as colloquial text measurement formulas. Values from the ROC curve and AUC analysis showed that the performance of the colloquial text measurement formulas was excellent. In addition, there was a high correlation between the grading scores by a group of experts and the grading based on the colloquial text measurement formulas. Therefore, both the validity and reliability of the colloquial text measurement formulas developed in this study have been verified and they are expected to be useful in actual writing evaluations.

The purpose of this study is to measure and demonstrate the orality score for expression items in Korean grammar education. Accordingly, a total of 176 expression items were extracted from two copies of a Korean grammar dictionary, and the frequencies in the written and oral corpus were analyzed. Based on this, the orality score (G²) was calculated. As a result of evaluating the orality score, a total of 36 expression items were found to have colloquialism. A standard for grading orality scores was arranged, and the spoken expression items were graded accordingly. Furthermore, a method for visualizing these results was presented. The results of this study are significant in that they can be used as materials for teaching and learning Korean grammar, explaining grammar, and discriminating between spoken and written errors.

This study designs and conducts Introduction to Japanese classes for novice learners in Japanese based on the Task-based Language Teaching method, a communication-centered teaching method, and Focus on Form Theory. In the existing lecture type classes, the students did not have the opportunity to use Japanese and eventually stopped learning Japanese. In Japanese classes that has implemented the Task-based Language Teaching method and the Focus on Form, the goal is to properly use the Japanese that has been learned. The first step of the study organizes the meaningful parts in the Communication Centered Teaching Method and FonF study for novice Japanese learners. Next, by using FonF and TBLT, classes are conducted in order to develop communicative competence for novice learners. The results of the study examines the class satisfaction survey completed by the learners. In the psychological section of the learners, there was a positive effect in the Task activities classes, and this has also positively affected the learning experience for the target language. Classes that utilized tasks provided more opportunities to use Japanese, and also successful experiences in learning Japanese had increased which led to high motivations in learning Japanese. Furthermore, tasks that were highly applicable to daily life allowed students to learn more meaningful and practical Japanese.
그림책을 이용한 토론 수업이 초등학생의 읽기 동기와 자아존중감에 미치는 영향

이 연구의 목적은 그림책을 이용한 토론 수업을 개발하고 이를 적용한 후 학생들의 읽기 동기와 자아존중감에 미치는 영향을 검증하는 것이다. 그림책을 이용한 토론수업을 실시한 집단과 실시하지 않은 집단 간의 읽기 동기와 자아존중감 차이를 알아보기 위해 국내 읽기 동기 관련 선행 연구를 파악하고 ADDIE 설계모형 단계의 절차를 거쳐 초등학교 교육과정에서 활용 가능한 토론 수업을 개발하였다. 연구 대상은 경기도 용인시 기흥구에 소재한 G 초등학교에 재학 중인 3학년 20명의 학생들이고 통제집단으로 같은 학교, 같은 학년의 19명 학생들을 선정하였다. 그림책을 이용한 토론 수업은 2019년 9월 1일부터 11월 30일까지 진행되었으며 5권의 그림책으로 총 15차시 수업을 하였다. 프로그램의 효과를 검증하기 위하여 사전-사후 읽기 동기, 자아존중감 검사를 하였고, SPSS 23.0 프로그램을 이용하여 통계분석을 하였다. 또한 수업 후 소감문, 더 읽은 횟수, 개인 면담 분석을 통해 수업 과정 중 읽기 동기 및 자아존중감 향상이 어떻게 이루어지는지 질적 분석을 하였다. 본 연구의 결과를 요약하면 첫째, 그림책을 이용한 토론 수업은 초등학생의 읽기 동기의 총점, 호기심, 도구적 가치, 인정, 성취 요인을 향상하는 데 효과적이었다. 둘째, 그림책을 이용한 토론 수업은 초등학생의 자아존중감 총점, 총체적 자아존중감, 사회적 자아존중감, 가정적 자아존중감 요인의 향상에 효과적이었다. 이러한 결과들은 체계적인 읽기 내적 동기 향상을 위한 교육적 활동의 개발과 학생들의 공감과 소통을 통한 자아존중감 향상 프로그램의 필요성을 시사한다. The purpose of this study was to develop discussion activities using picture books and apply them to verify the impact on students' motivation for reading and self-esteem. To this end, a new picture book reading program was developed for 3rd graders through the procedure of ADDIE model. The study was conducted in G Elementary School in Yongin city with 39 students (20 experiment groups and 19 control groups) from September 1 to November 30, 2019. Pre- and post-reading motivation and self-esteem tests were conducted to verify the effectiveness of the program, and statistical analysis was conducted using the SPSS 23.0 program. In addition, qualitative analysis was conducted on how reading motivation and self-esteem improve during the course by analyzing discussion class activity, post-class impressions, the number of readings, and personal interviews. To sum up the results of this study, firstly, discussion activities using picture books were effective in improving the total score, curiosity, tool value, recognition, and achievement factors of elementary school students' reading motivation measures. Second, discussion activities using picture books were effective in improving the total score of self-esteem, global self-esteem, social self-esteem, and family self-esteem factors of elementary school students. These results suggest the need for a program to develop educational activities to improve systematic internal reading motivation and to improve self-esteem through students’ empathy and communication.
PCR-RFLP Identification of Three Major Meloidogyne Species in Korea

Partial mitochondrial DNA from single female or second stage juvenile (J2) of root-knot nematodes was amplified by PCR (polymerase chain reaction), and the further analysis by RFLP (restriction fragment length polymorphism) provided discriminatory profiles useful for three major Meloidogyne species, M arenaria, M incognita, and M hapla, in Korea. The nematode DNA was extracted individually in nuclease-free water. The sizes of PCR product (1.7 kb and 500 bp) and restriction patterns obtained from single female nematodes were consistent with the results from single J2 within the same species. M. hapla was easily differentiated from the two other root-knot nematode species by the size of the PCR products. A fragment of 500 bp was generated from M. hapla, while M. arenaria, and M. incognita produced an 1.7 kb fragment in PCR amplification. M arenaria could be distinguished from M. incognita by analysis of restriction enzyme digestion with HinfI or Alu I. Hinf I had no digestion site in mitochondrial DNA of M. arenaria; however, it generated 1.3 kb and 400 bp fragments in M. incognita. Alu I digestion resulted in 1 kb, 460 bp, and 250 bp fragments in M. arenaria, but showed different digestion patterns in M. incognita by generating 800 bp, 460 bp, 250 bp, and 150 bp fragments.

The subthreshold characteristics of double-gate (DG) MOSFETs with various thicknesses of a Si film (TSi) are analyzed. It is found that, in comparison to the symmetrical DG-MOSFET, the subthreshold characteristics of the lightly-doped asymmetric device have a larger dependence on TSi, which is due to the linear distribution of the potential in the Si-lm region. Further, we derive an analytical equation which can explain these phenomena and verify the accuracy of the analytical equation by comparing them with the device simulation results. Due to these TSisensitive subthreshold characteristics, tight control of TSi is required for lightly-doped asymmetric DG-MOSFETs to keep a large Ion/Ioff ratio.
