The purpose of this study was to compare the effects of two different types of texts, which were narrative and expository, on the understanding of content. Elementary students' perceptions of the two types of the texts were also investigated. In the comparison of the effects on the understanding of the text contents, test scores of mind-mapping, closed-answer question, and essay test were used. The analyses of mind-mapping tests showed narrative text was more effective to figure out main concepts of the text throughout the mind-mapping test. But expository text was more effective in the hierarchical organization of the concepts. In the closed-answer questions and essay test, narrative text was more effective than expository text. However when the contents of text were difficult and complex, there was no meaningful difference between the two types of texts. The analyses of students' perceptions of the texts showed that narrative texts were preferred. Students perceived that the narrative text was more interesting and familiar. However, the perceptions of helpful text for their science learning were not different by the types of texts.

The purpose of this study was to compare socio-linguistic characteristics and instructional influences of two different types of texts, which were narrative and expository. Socio-linguistic characteristics of two different types of texts were analyzed in their content specialization, linguistic formality, and social-pedagogic relationships. Expository texts showed strong scientific classification, and medium level of linguistic formality, and low level of social-pedagogic relationships. Narrative texts showed different characteristics. The instructional effects were investigated with 91 fifth grade elementary students in three classes. Each class was randomly assigned into three groups: expository text group, narrative text group, control group. The results showed that the science achievement scores of the narrative text group was higher than those of other groups. The affective domain test scores of the expository text group were higher than other groups. The perception of students on informational science text were generally positive both types of texts.

이 연구는 고등학생들의 지질 답사 보고서에 나타난 내러티브 텍스트와 Bruner가 제시한 두 가지 사고 양식 - 패러다임적 사고와 내러티브적 사고 그리고 학업 성취도가 어떻게 관련되는 지 살펴보고자 했다. 연구의 주요 목표는 특정한 상황에서 나타난 내러티브 텍스트의 사용여부로 학생들의 내러티브적 사고 경향을 구별하고, 우세한 사고 경향에 따라 인지적 성취 결과에 차이가 나는지 분석하는 것이다. 고등학교 2학년 학생 145명의 지질 답사 보고서의 텍스트 분석과 함께 답사지에 대한 회상 검사, 학업 성취도, 면담을 통하여 양적, 질적 연구를 수행했다. 텍스트 분석 결과, 학생들의 보고서에는 설명적, 논증적 텍스트와 함께 내러티브 텍스트가 상당 수 발견되었는데 이는 야외 답사지에서 학생들이 느끼는 심리적 상황과 지구과학 학습 및 현행 교육과정의 특징과 관련이 있는 것으로 추측된다. 내러티브 텍스트로 보고서의 내용을 재구성한 학생들은 그렇지 않은 학생들에 비하여 3개월 후에 실시한 회상 검사에서 높은 점수를 받았으나, 지구과학 I의 학업 성취도에서는 여학생들의 경우에만 더 높은 성취도가 나타났다. 내러티브 텍스트의 사용 여부로 내러티브적 사고와 패러다임적 사고 경향을 판단할 수 있는지 학생들과의 면담을 병행하여 조사한 결과, 내러티브 텍스트 사용과 사고 경향이 일치하지 않는 학생의 사례가 나타났다. 학습 내용에 따라 내러티브적 사고와 패러다임적 사고를 유연하게 사용할 수 있는 학생은 학습에 성공적이며 학업 성취도에서 좋은 결과를 나타내는 것으로 조사되었다.

The importance of the standards and its related texts established by Codex Alimentarius Commission (CAC) had been increased by the Agreement of Application of Sanitary and Phytosanitary Measures (SPS Agreement) in World Trade Organization (WTO). To meet the needs of WTO SPS Agreement, biennial CAC meeting had been changed to every year. This study was conducted to analyze the effects on interval between CAC meetings. The years of adoption, revision and amendment of CAC texts were collected from the official standard list and individual texts from CAC homepage. The period since establishment of CAC was divided into four groups by starting negotiation of Uruguay Round, WTO foundation and reducing the interval between CAC meetings. The collected data were analyzed by SPSS program. The numbers of CAC standards, guidelines, recommendations, maximum residue levels, and miscellaneous texts were 202, 56, 46, 3 and 5, respectively. Since 8 documents didn't contain the adoption year, these texts were eliminated to analyze adoption year. For adoption, annually 11.26 texts were established since establishment of CAC and there were no significant difference among the 4 groups. However the average numbers of revisions and amendments of adopted texts for overall periods and for each period were 7.56, 0.93, 6.50, 17.20 and 19.75, respectively. The average numbers of overall decisions, defined as summation of adoption, revision and amendment of texts, for overall periods and for each period were 12.37, 6.27, 9.00, 17.40 and 29.25, respectively. There were significant differences by the WTO foundation and the interval between CAC meetings. The reduced interval of CAC meetings influenced to increase number of revisions and amendments of adopted texts, but not yet adoption of new text.

In this study, the readability of the texts in the third and the sixth grade science textbooks developed under the 2007 revised science curriculum were analyzed in terms of word and sentence units. In the word unit analyses, the levels of the words in the texts were classified into four categories, 1st to 4th levels. In the sentence unit analyses, the sentences in the texts were classified either a simple sentence or compound/complex sentences, and the average length of the sentences was also calculated. The results indicated that more than 90 percents of the words in the 2007 revised science textbooks were classified as the 1st to the 3rd levels. However, both the kinds and the frequencies of the words in the 2007 revised science textbooks were increased in comparison of those in the 7th science textbooks. In particular, it was found that the increasement in the 3rd grade science textbook was noticeable. The ratio of the compound/complex sentences in the 2007 revised science textbooks were increased in comparison of those in the 7th science textbooks. The average length of the sentences in the 2007 revised science textbooks was also increased.

이 연구는 교수요목기부터 7차 교육과정까지의 모든 과학(자연) 교과서에서 공통적으로 제시되는 '기압'과 '바람'을 다루는 텍스트를 체계기능언어학적으로 분석하였다. 연구 결과는 다음과 같다. 관념적 메타기능 측면에서 과학적 정보를 많이 담고 있는 텍스트는 교육과정 개정에 따라 줄어든 것으로 나타났다. 대부분의 정보의 형태는 '원리'보다는 '정의'와 '사실'이었다. 상호적 메타기능 측면에서 학생과 텍스트 사이의 거리는 점점 줄어들었으며, 학생들의 사회적 지위는 교육과정 개정에 따라 점차적으로 고려되었다. 구성적 메타기능 측면에서 전문적 용어와 기호의 비율은 감소 추세에 있었으나, 과학 교과서에서 텍스트양 또한 줄어든 것으로 나타났다. 초기에는 문장에 주어가 제시되었으나, 시간이 흐르면서 주어가 생략되었다. 또한 주어와 문장 첫 구의 일치율은 7차의 교과서 텍스트에서 그 일치도가 현저히 줄어든 것으로 나타났다.

This paper employs a computer-aided text analysis (CATA) and a Critical Discourse Analysis (CDA) to explore the strategies of recruitment and intellectual polarization in ISIS (Islamic State in Iraq and Syria) media. The paper's main objective is to shed light on the efficacy of employing computer software in the linguistic analysis of texts, and the extent to which CATA software contribute to deciphering hidden meanings of texts as well as to arrive at concise and authentic results from these texts. More specifically, this paper attempts to demonstrate the contribution of CATA software represented in the two variables of Frequency Distribution Analysis (FDA) and Content Analysis (CA) in decoding the strategies of recruitment and intellectual polarization in one of ISIS 's digital publication: Rumiyah (a digital magazine published by ISIS). The analytical focus is on three strategies of recruitment and intellectual polarization: (i) lexicalization, (ii) intertextual religionisation, and (iii) justification. Two main findings are revealed in this study. First, the application of CATA software into the linguistic investigation of texts contributes effectively to the understanding of the thematic and ideological messages pertaining to the analyzed text. Second, the computational analysis guarantees concise, credible, authentic and ample results than is the case if the analysis is conducted without the work of computer software. The paper, therefore, recommends the integration of CATA software into the linguistic analysis of the various types of texts.

In this study, the gender-role stereotyping of the texts and the illustrations in the elementary science textbooks developed under the 2009 Revised National Curriculum was analyzed, and the results were compared with those of the 2007 Revised National Curriculum. In the texts, there were significant differences between boys and girls in the frequencies of texts, two types of learning activities such as scientific inquiry and emotional expression, and housekeeping activity. Women outnumbered men in housekeeping activity, but they were much less than men to perform outdoor and professional activities. In the illustrations, there were not significant differences by gender in pupils, and these results are desirable in terms of achieving balance between boys and girls. However, the textbooks were found to favor the illustrations of men especially in outdoor and professional activities. Women also performed more in housekeeping activity. Compared with the adult results of previous curriculum, these results were not improved at all.

Recently various studies on various applications using images taken by mobile phone cameras have been actively conducted. This study proposes a correction method for misrecognition of Korean Texts in signboard images using improved Levenshtein metric. The proposed method calculates distances of five recognized candidates and detects the best match texts from signboard text database. For verifying the efficiency of the proposed method, a database dictionary is built using 1.3 million words of nationwide signboard through removing duplicated words. We compared the proposed method to Levenshtein Metric which is one of representative text string comparison algorithms. As a result, the proposed method based on improved Levenshtein metric represents an improvement in recognition rates 31.5% on average compared to that of conventional methods.
