It is crucial for the social media based marketing practices to perform sentiment analyze the unstructured data written by the potential consumers of their products and services. In particular, when it comes to the companies which are interested in global business, the companies must collect and analyze the data from the social media of multinational settings (e.g. Youtube, Instagram, etc.). In this case, since the texts are multilingual, they usually translate the sentences into a certain target language before conducting sentiment analysis. However, due to the lack of cultural differences and highly qualified data dictionary, translated sentences suffer from misunderstanding the true meaning. These result in decreasing the quality of sentiment analysis. Hence, this study aims to propose a method to perform a multilingual sentiment analysis, focusing on Korean-Chinese cases, while avoiding language translations. To show the feasibility of the idea proposed in this paper, we compare the performance of the proposed method with those of the legacy methods which adopt language translators. The results suggest that our method outperforms in terms of RMSE, and can be applied by the global business institutions.

The purpose of this study is to develop an argument-based modeling strategy, utilizing writing and argumentation for communication in science education. We need to support students and teachers who have difficulty in modeling in science education, this strategy focuses on development of four kinds of factors as follows: First, awareness of problems, recognizing in association with problems by observing several problematic situations. Second is science concept structuralization suggesting enough science concepts by organization for scientific explanation. The third is claim-evidence appropriateness that suggests appropriate representation as evidence for assertions. Last, the use of various representations and multimodal representations that converts and integrates these representations in evidence suggestion. For the development of these four factors, this study organized three stages. 'Recognition process' for understanding of multimodal representations, and 'Interpretation process' for understanding of activity according to multimodal representations, 'Application process' for understanding of modeling through argumentation. This application process has been done with eight stages of 'Asking questions or problems - Planning experiment - Investigation through observation on experiment - Analyzing and interpreting data - Constructing pre-model - Presenting model - Expressing model using multimodal representations - Evaluating model - Revising model'. After this application process, students could have opportunity to form scientific knowledge by making their own model as scientific explanation system for the phenomenon of the natural world they observed during a series of courses of modeling.

Given the context that users are actively using social media with multimedia embedded information, the purpose of this study is to demonstrate how images are used within Twitter messages, especially in influential and favorited messages. In order to achieve the purpose of this study, the top 200 influential and favorited messages with images were selected out of 1,589 tweets related to "Boston bombing" in April 2013. The characteristics of the message, image use, and user are analyzed and compared. Two phases of the analysis were conducted on three data sets containing the top 200 influential messages, top 200 favorited messages, and general messages. In the first phase, coding schemes have been developed for conducting three categorical analyses: (1) categorization of tweets, (2) categorization of image use, and (3) categorization of users. The three data sets were then coded using the coding schemes. In the second phase, comparison analyses were conducted among influential, favorited, and general tweets in terms of tweet type, image use, and user. While messages expressing opinion were found to be most favorited, the messages that shared information were recognized as most influential to users. On the other hand, as only four image uses - information dissemination, illustration, emotive/persuasive, and information processing - were found in this data set, the primary image use is likely to be data-driven rather than object-driven. From the perspective of users, the user types such as government, celebrity, and photo-sharing sites were found to be favorited and influential. An improved understanding of how users' image needs, in the context of social media, contribute to the body of knowledge of image needs. This study will also provide valuable insight into practical designs and implications of image retrieval systems or services.

It is impossible that the corporation can make up good corporate images with sales promoting and pursuing profits only. To form impressive oorporate images, the corporation should acquire efficient marketing images and social oonfidences with the investment for the culture, the art, the preservation of public health, educations and social welfare programs. The oorporate image is indined to be formed by audiences subjectively even though the corporation makes great efforts to have its unique images. The audience has a tendency to have their subjective opinions about the corporate image based on several informations communicated by the corporation and various sources. The sensitive approach and emotional persuation can be efficient for making good corporate images because corporate images of audiences arise from emotional and sensitive factors rather than rational ones. There are many previous studies verifying that the humor effect should be one of powerful means for inducing concentrations, memorizations and persuations. The majority of popular advertisings are humor touched one and the questionaire proves that almost all university students participating sample test, prefer humorous advertisings to serious advertisings. The questionaire verifies that it is a most efficient method is using humor effects at product advertising to improve the corporate image indirectly. And there are very possitive reactions about applying humor effects for the corporate image advertising and the other advertisement types such as pamphlets and catalogues. The humor effect motivates the persuation with spiritual pleasures and intimacy, and it minimize the negative aspects of advertising for the formation of the corporate image. The humor effect is valuable not only for the formation of the corporate image reflecting the entity of the oorporation itself but also for the ideation of advertising communications. The study on the humor effect related with the corporate image is significant because the humor is a different version of the humanism based on deep oontemplation and oomprehension of human life rather than simple means to motivate laughers.

The accessibility and effect of cartoon on children are very significant. Since cartoon is a medium of conveying information through text and pictures, it has a characteristic of being easily approached by children than any other medium. Its accessibility to children is inevitably more exceptional than any other medium in the sense that it is a method of not only telling or reading stories but also showing stories. The main audience of is children. It has a characteristic of being easily accepted by children since it's mythology seen in cartoon than read in text. However, gods conducts are full of unethical expressions. Sexual expressions of intermarriages between mother and son, between brother and sister and between uncle and niece, as well as extramarital intercourse are very unethical that could have negative effects on children. This study analyzed the unethical expressions of gods that could have negative effects on children at current point in time. Zeus was often unfaithful to his wife with many stories about the children of Zeus that were created from extramarital intercourse. Standard of value on rational decision has been established for adult readers, but children can readily accept things since they lack their own rational decision on what's right and wrong. As an alternative to children's uncritical observatory study, there is a need for author's intervention to help children form desirable values. The purpose of this study is to analyze the sexual expressions of Zeus and gods in that could affect children's social study.

The purpose of this study was to investigate the change in beginning science teachers' inquiry-oriented teaching practice through mentoring program. Participants in this study are three mentor teachers and three beginning teachers. The three beginning teachers are middle school science teachers who have less than four years teaching experience. Also three science teachers participated in the program as mentors, who have more than twelve years teaching experience. We collected data such as video recordings of beginning teachers' classes, lesson plans, recordings of one to one mentoring and RTOP class observation reports. Mentor teachers observed and analyzed five classes of each beginning teacher. Before the mentoring program, beginning teachers' teaching methods were more concept-oriented and teacheroriented. They rarely used inquiry-elements including prediction, reasoning, hypothesizing and students were not actively engaged in communicative interactions in a classroom. But during the mentoring program, these teachers recognized and responded to student diversity and encouraged all students to participate in science learning. Beginning teachers' teaching methods have changed to become student-oriented, teachers and students collaborated in pursuit of ideas, and students often initiated new activities relevant to an inquiry. As a result, this mentoring program provided beginning teachers the opportunities to reflect on their own teaching and reform their classes. The results show that school-centered mentoring program is helpful to enhance beginning science teachers' inquiry-oriented teaching ability.
