  • Given the importance of early experience in algebraic thinking, we designed six consecutive lessons in which $4^{th}$ graders were encouraged to recognize patterns in the process of finding the relationships between two quantities and to represent a given problem with various mathematical models. The results showed that students were able to recognize patterns through concrete activities with manipulative materials and employ various mathematical models to represent a given problem situation. While students were able to represent a problem situation with algebraic expressions, they had difficulties in using the equal sign and letters for the unknown value while they attempted to generalize a pattern. This paper concludes with some implications on how to connect algebraic thinking with students' arithmetic or informal thinking in a meaningful way, and how to approach algebra at the elementary school level.

  • LCP(Life Cycle Profiles) of bridge structures are indispensable for the LCC(Life Cycle Cost) evaluations of bridge system. The bridge under considerations may be newly-designed one or one in service. Thus, a systematic study of LCP is essential for both reliable LCC evaluation and strategic bridge management. LCP is mainly influenced by the structural environment in nature. However, in Korea, LCC evaluation has been performed with the LCP of foreign research results or only with the pieces of professional engineers' opinion. Therefore, to alleviate the drawbacks of foreign LCP and to enhance the reliability of current LCP, LCP should be established using the available data in bridge management system(BMS). In this study, LCP along with a subset of the BMS data was investigated and several mathematical expressions were proposed and evaluated. The condition ratings of a bridge were trasformed into the numerical indices through fuzzy logics with real field data. From the numerical results, it is concluded that the mathematical LCP model of $y=\sqrt{y^2_0-at}$ is shown to be the fittest one (R=0.815) to express the condition rating varied with the age. This has been drawn from the case study of slab bridges under the similar conditions.

  • Imitation is an important cultural act that began with human history, and is becoming an essential strategy for innovation and creativity in the 21st century. With the advent of the concept of intellectual property in modern society, the issues of imitation and design have become inseparable. This study, in that it is necessary to understand the cultural identity of the times for the Design Studies, examined the significance of imitation of TV reality audition programs, JTBCand Mnet with a theme of "Mimic Singing" and "LipSync." First, the act of imitation itself is fair and entertaining. Second, imitation ironically expresses the power of originality. Third, imitation is eventually expanding into mixing and transformation. Through these series of processes, the act of imitation goes beyond one-sided follow-up and leads to the intention of improving it creatively. Thus, it is concluded that the issue of imitation is complementary, not mutually exclusive, as an inseparable concept from creativity.

  • This study was to explore the meaning and implications of nurses' representations in newspapers from the perspective of convergence. Four different Korean newspaper articles from Aug. 2003 to Sep. 2013 were analyzed by using a descriptive exploratory qualitative study, thematic analysis. Five themes were derived from the data analysis. In the newspaper, in general, professional nurses were described as patient-centered nursing provider with sense of calling for nursing. Also their positive portrayals as health professionals have noticeably emerged. Yet in contrast, nurses' negative portrayals as neglectful, lazy, and discriminating against the poor have been reported. The study findings indicate significantly enhanced nursing professionalism and nursing as a future-promising occupation. The results can be used to develop strategies to improve nursing public image in the media. For further exploratory study on the subscriber's image of nurses after reading the articles is needed.

  • As many CSR activities grow steadily, how charitable giving messages affect donation attitude is received attention. In the current research, temporal orientation and donation recipients is presented an effective variables to judge a organization activities. This article based on CLT theory, we establish the experimental condition focused on interaction effects between two variables: time orientation in charitable activities outcomes(near future: a week vs. far future: a year); and based on the recognizability of recipients(a individual child vs. collective group). Result from study, charitable activities outcomes generated in near future orientation(far future orientation) increase donation attitude and affective when messages are used in a specific(general group) context. Furthermore, empathy of CSR organization is a mediator on donation attitude and affective. We expect that these findings have important implication for charitable giving strategy.

  • Documentaries based on facts not only contain the spirit of that era but have been transformed in various ways according to changes in technologies and media. This study analyzed under the premise that the original documentary of YouTube plays a role in representing the characteristics of the medium. YouTube's original documentary is released on YouTube and then re-edited and released as a documentary film, and has the same shooting source, and is edited and described differently depending on whether it is a YouTube or a movie. This is the content that can confirm the media differences between YouTube documentary and documentary film. The cinema version shows the difference in that the narrative is developed using third-person narration and subtitles, mainly for handheld shooting and smooth editing, and the YouTube version is developing the narrative centering on audio-centric rough editing, interviews and background music. Through this, it can be seen that the YouTube version reinforces intimacy through a personal and direct expression method, while the cinema version reinforces objectivity through an official and indirect expression method.

  • The knowledge-information-processing competency is the most essential competency in a knowledge-information-based society and is the most fundamental competency in the new problem-solving ability. Data-driven science inquiry, which emphasizes how to find and solve problems using vast amounts of data and information, is a way to cultivate the problem-solving ability in a knowledge-information-based society. Therefore, this study aims to develop a teaching-learning model and strategy for data-driven science inquiry and to verify the validity of the model in terms of knowledge information processing competency. This study is developmental research. Based on literature, the initial model and strategy were developed, and the final model and teaching strategy were completed by securing external validity through on-site application and internal validity through expert advice. The development principle of the inquiry model is the literature study on science inquiry, data science, and a statistical problem-solving model based on resource-based learning theory, which is known to be effective for the knowledge-information-processing competency and critical thinking. This model is titled "Exploratory Scientific Data Analysis" The model consisted of selecting tools, collecting and analyzing data, finding problems and exploring problems. The teaching strategy is composed of seven principles necessary for each stage of the model, and is divided into instructional strategies and guidelines for environment composition. The development of the ESDA inquiry model and teaching strategy is not easy to generalize to the whole school level because the sample was not large, and research was qualitative. While this study has a limitation that a quantitative study over large number of students could not be carried out, it has significance that practical model and strategy was developed by approaching the knowledge-information-processing competency with respect of science inquiry.

  • In modern information society, the necessity arose of having to manage overall information technology as information technology is introduced to companies and public organizations while the necessity of joining the goals of business and IT is increasing. Also, there has been an increase in organizations which are preventing the overlapping of IT investigations and pursuing ROI. Hereupon, many developed companies created the concept of IT governance. IT governance indicates the structure and dynamic behavior of companies' business and the structural affecting factors influencing IT, and this is expressed as business, the business & IT related committees and departments inside and outside, the framework representing their relationship and range of activity, organizational diagram and process composition. Intermingled with such external factors, the reestablishment of defense IT governance in order to reach the vision and goal of our current military defense has become a requirement. This study aims to describe core strategy for building defense IT governance framework. In order to support these claims, the comprehensive IT governance and information technology are mentioned, domestic and overseas military cases are analyzed, and core strategy for building defense IT governance framework is analyzed as well.

  • Recently the era of software integration which is expressed in words of the fourth industrial revolution has begun. Thus the need of the software education for the non-major preservice teachers who are cultivating future talent has been increasing and it is necessary to foster a positive attitude toward software education of non-major preservice teachers. The purpose of this study is to verify the causality between the computer learning attitude factors of non-major preservice teachers in the software education class. To analyze the causality, we performed correlational analysis and regression analysis between the exterior factors of attention, self-learning, application of learning and the other interior factors of computer learning attitude. As a result, the significant factor of attention was interests, and the significant factor of self-learning was superiority, and the significant factors of the application of learning were the sense of purpose and the motive of accomplishment.
