The wordless comics means comics without word and only the image. The study treats the research and the analysis on the wordless comics as the transition. The degree of study are the wordless comics is used as transition with material and scene, with subject and narrative and so on. These practical use of the wordless comics influence how much dramatic effect with comics rather than text comics.

The purpose of this study was to investigate how a science magazine played a role in filling the gap between scientists and the general public, and how it contributed to science popularization. We analyzed the linguistic features of the texts used in a science magazine. We used 12 articles (six written by journalists, and six written by scientists) from the Science Donga. Register analysis was conducted in order to define the linguistic features of the texts in terms of ideational meaning, interpersonal meaning and, textual meaning. Results of this study are as follows: (1) the articles written by journalists used a higher mental and verbal processes in which the conversations and thoughts of scientists were expressed. (2) Human agents were relatively explicit in the journalists' articles. However, they were implicit or omitted in the articles of scientists. (3) Interrogative sentences and inclusive imperative sentences, and even omissions were frequently found in the journalists' articles whereas scientists' articles mainly used declarative statements. (4) The clause density of journalist' articles and scientists' were similarly lower than that of science textbooks. (5) The information structure revealed by the patterns of Theme and Rheme that the journalists' articles used in science magazines was simpler than that of science textbooks, while the structure of scientists' articles was more complex than that of journalists'. Based on the linguistic features of the texts used in science magazines, we found that a science magazine contributes to science popularization in two faces: One is in that the articles of journalists present science contents in a way that the readers can follow with ease and feel well-acquainted. The other is that the modified articles of scientists help the general public get familiar with the culuture of science in terms of use of science language.

This study analyzed the 6th grade elementary science textbook 'Science stories' reading process of students by utilizing eye movement tracking techniques. Participants read 3 articles in the new experimental science textbooks and solved 9 problems about each article. By understanding and academic achievement results, participants were divided into high-groups, middle-groups, and low-groups. The results of eye movement characteristics of the high-groups and low-groups had the following differences. Number of fixations and number of regressions were higher in high-groups. Average fixation duration and average regressive fixation duration were longer in low-groups. Fixation time for the key sentence of the article was longer in high-groups. Analysis of a scan path and post-interview, high-groups had frequent regression between sentences and they knew where the core of the article is and paid much attention there. In contrast low-groups are sequentially read most articles and some of them had a leap of abnormal range. Problem-solving approach is also different between groups. In conclusion reading style is associated with the science stories comprehension and students who had more regressions, much core search process, effective attention distribution, high concentration showed better understanding results. Also words or sentences used in textbooks are associated with science stories comprehension.

A Blog provides commentary, news, or content on a particular subject. The important part of many blogs is interactive format. Sometimes, there is a heated debate on a topic and any article becomes a political or sociological issue. In this paper, we proposed a method to predict the popularity of an article in advance. First, we used hit count as a factor to predict the popularity of an article. We defined the saturation point and derived a model to predict the hit count of the saturation point by a correlation coefficient of the early hit count and hit count of the saturation point. Finally, we predicted the virtual temperature of an article using 4 types(explosive, hot, warm, cold). We can predict the virtual temperature of Internet discussion articles using the hit count of the saturation point with more than 70% accuracy, exploiting only the first 30 minutes' hit count. In the hot, warm, and cold categories, we can predict more than 86% accuracy from 30 minutes' hit count and more than 90% accuracy from 70 minutes' hit count.

The purpose of this study is to analyze the science reasoning differences of elementary school students' science writing. For this purpose, science writing activities and analysis frameworks were developed. Science writing data were collected and analyzed. Third to sixth grade elementary students were selected from a middle high level elementary school in terms of a national achievement test in Seoul. A total of 320 writing materials were analyzed. The results of the analysis were as follows. Science writings show science reasoning at 52 % for $3^{rd}$ grade, 68% for $4^{th}$ grade, 85% for $5^{th}$ grade, and 89% for $6^{th}$ grade. Three types of scientific reasoning such as inductive reasoning, deductive reasoning, and abductive reasoning appeared in science writing of the third to sixth graders. The abductive reasoning appeared very low in comparing with inductive and deductive reasoning. Level three appeared the most frequently in the science writing of the elementary students. The levels of inductive and deductive reasoning in science writing increased according to increasing grade and showed statistical differences between grades. But the levels of abductive reasoning did not show an increasing aspect according to increasing grade and also did not show statistical differences between grades. The levels of inductive reasoning and deductive reasoning of the 3rd grade was very low in comparing with the other grades.

As the transaction volume of the C2C second-hand market is growing, the number of frauds, which intend to earn unfair gains by sending products different from specified ones or not sending them to buyers, is also increasing. This study explores the model that can identify frauds in the online C2C second-hand market by examining the postings for transactions. For this goal, this study collected 145,536 field data from actual C2C second-hand market. Then, the model is built with the characteristics from postings such as the topic and the linguistic characteristics of the product description, and the characteristics of products, postings, sellers, and transactions. The constructed model is then trained by the machine learning algorithm XGBoost. The final analysis results show that fraudulent postings have less information, which is also less specific, fewer nouns and images, a higher ratio of the number and white space, and a shorter length than genuine postings do. Also, while the genuine postings are focused on the product information for nouns, delivery information for verbs, and actions for adjectives, the fraudulent postings did not show those characteristics. This study shows that the various features can be extracted from postings written in C2C second-hand transactions and be used to construct an effective model for frauds. The proposed model can be also considered and applied for the other C2C platforms. Overall, the model proposed in this study can be expected to have positive effects on suppressing and preventing fraudulent behavior in online C2C markets.

이 연구는 인터넷 소설을 읽을 때 사용자의 참여도에 따라 그 내용의 이해도가 어떻게 영향을 받는지 알아 보고자 한다. 현재 인터넷 소설은 소설의 양식이 인쇄매체에서 인터넷 매체로 옮겨졌음에도 불구하고 인터넷이라는 매체의 특성을 활용하지 못하고 있다. 인터넷 매체의 여러 특징들 가운데 상호작용성은 인쇄매체에서 인터넷 매체로의 전환을 이룬 다른 장르에서 주요 특징으로 고려되고 있다. 이것은 디지털 스토리텔링에서 사용자의 활동(action)에 관한 부분으로 활동적인(active) 사용자의 참여를 말한다(이 연구에서는 상호작용성을 사용자가 매체에 활동을 통한 개입, 사용자 참여도로 조작적 정의를 내린다). 또한 모니터를 통한 글 읽기는 인쇄매체에 비해 가독성이 떨어지고 훑어보는 글읽기(scanning)가 이루어지기 때문에 내용을 이해하는 데 어려움이 따른다. 인터넷 매체의 특성을 살리면서 글에 대한 이해도를 높이기 위해 사용자의 참여도를 독립변인으로 글의 이해에 미치는 영향을 알아보고자 했다. 실험 1에서는 기존의 단편 추리 소설을 이용해 사용자의 글읽기 과정에서 범인추측의 정도에 차이를 주어 참여도에 변화를 주었다. 그 결과 사용자의 참여도에 따라 이해의 정도가 유의미함을 보였다. 이는 사용자의 참여도가 이해에 영향을 미친다는 기존 연구를 뒷받침하며 인터넷 소설에서 인터넷 매체의 특성을 살린 글의 기재가 글의 이해에 도움이 된다는 것을 말해준다. 실험 2에서는 실험 1과 같은 추리 소설을 이용하되 사용자의 참여도에 따라 소설 내용의 변화를 주었다. 실험 2의 결과 내용 변화에 따른 이해도의 차이는 나타나지 않았으나 자신이 선택하지 않은 경로로의 이야기 내용에 궁금증을 보고하며 글의 전체 내용에 관한 관심을 보였다. 이는 사용자의 참여가 글의 이해뿐만 아니라 흥미유발에도 영향을 미친다는 가능성을 보여주므로 상호작용적인 글읽기와 흥미유발에 관한 추후연구가 필요함을 시사한다. 이 연구는 또한 기존의 인터렉티브 스토리텔링 연구가 현 상황에 대한 보고와 구현된 시스템의 사용성 평가에 국한된 것에 반해 실험 연구로의 변화를 꾀하였다는 것에 의의를 둘 수 있다.

Recently, comics pulication industry is experiencing long-time recess in Korean market. To overcome the difficulties firms are trying to develop various tools which fit new technological environments, but previous research tend to have focused too much on web-base contents such as webtoons, rather than communication effectiveness through social network services. Thus, this study investigated the relationship between the characteristics of postings at social network service and the consumer responsiveness. In the results, we found that posting with visual images and event invitations were positively associated with consumer responsiveness, and the amount of information was negatively associated with the responsiveness. This study shows some implications on how firms can effectively enhance communication with consumers through social network service.

This study is to help to understand the influence of exchange writing activity in the elementary mathematics on students' mathematical communication skill. Various technical activities had been implemented during the classes and the ideas from those activities had been interpreted into writings in the final stage of the classes. Those writings, then, were distributed to other students or teachers in order to devise a teaching model for exchange writing, which is to be applied to the 3rd grade classes and to identify the influence on the in mathematical communication skill. From this study, we could get such conclusions as follows: First, there was considerable difference between experimental group practicing exchange writing and control group engaging in normal learning activities in the progress of their mathematical communication skill (group discussion), writing skill and expressivity when examining their average communication skill using t-method. Similar trend had been witnessed when self-evaluating their mathematical communication skill. Second, when it comes to the mathematical tendency, experimental group showed a higher tendency in positiveness compared to the control group. Therefore, we might conclude that the exchange writing has a positive influence on the students' mathematical tendency, especially on their curiosity or interest in teaming, willingness to study and their comprehension of its importance.
