The purpose of this study was to examine how group argumentations mediated individual arguments by analyzing physics teachers' group argumentation and individual follow-up written arguments. Five in-service physics teachers participated in this study, two middle school and three high school teachers. The topics of argumentation included physics topics and pedagogy of them. Findings showed that the teachers constructed much more elaborated individual written arguments than group argumentation, which seemed to be resulted from different perceptions of teachers' verbal and written argumentations. Also, in their written arguments the teachers selectively utilized their colleagues' ideas shared during group argumentation. Lastly, teachers' argumentation showed different features between topics of physics and physics pedagogy. These differences were related to their orientations toward argumentation about content knowledge and teaching. These findings shed light on a productive physics teacher professional development in argumentation.

The "About Us" page on the website of a corporation provides information regarding the organization's vision, philosophy, and values. We examine the association between institutional information provided on corporate websites (i.e., the "About Us" section) with present and future financial performance. Utilizing a text mining technique, we analyze the institutional information of S&P500 firms in the year 2016. We conduct a factor analysis including words that are intentionally repeated in the introductory text of corporate websites. The results of the analysis reveal that keywords from this institutional information can be grouped into six factors. We then carry out an ordinary least squares regression analysis to determine the associations between these six factors and present financial performance. The results show that keywords in Factor 2 (those related to Purchasing experience) are positively associated with ROE, a variable representing present financial performance, while keywords in Factor 1 (those related to Note to customers) show a negative relationship with ROE. On the other hand, keywords in Factor 1 have a positive relationship with Tobin's Q, a variable representing future financial performance. These results indicate that there is some relationship between the words used in the institutional information in this section of corporate websites and firms' financial performance. Hence, the institutional information on a website may be a useful indicator of current firm performance and future firm value.

익명 네트워크 기술에 기반한 다크웹은 일반 표면웹보다 더 강화된 익명성을 제공한다. 최근 이 익명성을 악용하여 다수의 다크웹 사용자들이 다크웹 내에서 범죄 행위를 모의하는 행위가 꾸준히 발생하고 있다. 특히, 국내 다크웹 사용자들은 마약 유포를 위한 방법을 공유하거나 성착취물 유포 행위 등에 직간접적으로 가담하고 있다. 이와 같은 범죄 행위들은 수사 기관의 눈을 피해 현재까지도 계속해서 발생하고 있어 국내 다크웹 범죄 동향 파악의 필요성이 증대되고 있다. 그러나 다크웹 특성상 범죄 행위를 논의하는 게시글을 수집하기가 어렵고, 다크웹 내에서의 언어 사용 특성에 대한 이해 부족으로 그동안 다크웹 사용자들이 어떤 내용의 범죄를 모의하는지 파악하기가 어려웠다. 본 논문에서는 국내 사용자들이 활동하는 다크웹 포럼들을 중심으로 사용자들의 언어 사용 특성을 연구하고, 이를 통해 다크웹에서 다뤄지는 범죄 유형들을 분석한다. 이를 위해, 자연어처리 기반의 분석 방법론을 적용하여 다크웹에서 공유되는 게시글을 수집하고 다크웹 사용자들의 은어와 특정 범죄군에서 선호되는 언어 특성을 파악한다. 특히 현재 다크웹 내에서 사용자들 사이에 관측되는 어휘들에 대한 기술통계 분석과 유의어 관계 분석을 수행하였고, 실제 다크웹 내에서 사용자들이 어떠한 범죄에 관심이 많은지를 분석하였으며, 더 나아가 수사의 효율성을 증대시키기 위한 소셜미디어, URL 인용 빈도에 대한 연구를 진행하였다.

Purpose of this study is to clarify the effect of creative science writing for interest of biology and scientific attitude on high school student. Creative science writing is a learning method to enhance comprehension and expression of thinking of science contents related to daily life. 148 students were recruited and divided into two groups, experimental group were experience creative science writing lessons. On the other hand, contrary group were applied interest enhancement lessons excepted creative science writing activity. To investigate the effect of creative science writing, interest check of biology was used, and scientific attitude test was used to understand changes in student's scientific attitude. Experimental group had taught using creative science writing and their awareness of the instruction was analyzed with questionnaire. As a result of this study, the class based on creative science writing was effective in improving high school students' interest in biology and in particular it was helpful in promoting interest in biology and learning of biology. It suggested that the class based on creative scientific writing used a new teaching method unlike existing methods, caused them to have interest in the instruction by making them express their daily life freely not to memorize learning contents, applied learning contents to daily life through many kinds of writings and then enhanced their interest in biology. Indeed, the class based on creative science writing had the positive influence on changes in the scientific attitude of high school students. Since creative science writing is writing one's own idea through extensive thinking based on learning contents, it was effective in arranging the process of thinking and changing their scientific attitude into positive one. Consequently, it was concluded from the above results of the research that the teaching using creative science writing was available as the effective teaching methods to improve high school students' interest in biology and change their scientific attitude into positive one.

The information on SNS, which is created by the forms of postings and comments, is being magnified and redistributed to news media expanding its impacts on real words. This amplifying effects of SNS comments have been increasingly discussed but there still lacks the answers for which dimensions of information is magnified, and what affects the direction and the degree of the amplification. This study, therefore, explores the detailed dimensions that are magnified by SNS comments and how SNS posting structure and social network characteristics affect them by using sentiment analysis. By analyzing 2,378 Facebook postings and news articles and their 26,312 SNS and 74,730 news site comments, this study shows that SNS comments magnify the sentiments of the posting articles they are attached to. In comparison to news site comments, SNS comments magnify the cognitive and social dimensions more than the news site comments. In the affective dimension, they tend to magnify only the positive emotion more than news site comments. Also, the findings reveal that whether the article in the posting is written by the posting owner affects the degree of amplification when the comments are remained positive or switched positive, while the opposite determines the amplification when comments remain negatively, suggesting that the user relationship in social network is the important factor that affects the direction and the degree of the information amplification in SNS.

This study investigated and analyzed the contents of writing learning, self-evaluation of writing ability, recognition of writing ability, and recognition of writing education direction to J university students in order to analyze the perception of writing of university students and find ways to improve writing education. Through this, the improvement plan of writing education was discussed. As a result of researching and analyzing the perceptions of university students, college students perceived writing ability as important, and they wanted practical writing classes that received feedback and wrote actual writing rather than theoretical classes. In addition, it was found that they wanted to develop their ability to construct and develop the contents of the article. In order to make writing education a practical competency for college students, theoretical lectures are important, but it is necessary to give enough time and opportunity to write in practice, and to develop customized practical writing. Also, it is necessary to make writing class that students can participate through various teaching methods, and to make writing ability lead to practical competence even after graduation through the method of university graduation certification requirements. This study is meaningful in that it can seek the direction of university writing education through the recognition of college students related to writing.
