  • In recent years, an increasing number of viewpoints hold that students should be engaged in a learning environment where understanding and knowledge transfer take place. This study introduces Mathematics Created by You (MCY)-mentoring program, which allows students to construct artefacts that are required to learn. This program is online-based and so can be shared by several people and mathematics leaning takes place through interactions within this carefully designed environment. Also, MCY intends to provide students a series of sequential activities related to creative play, creative learning and creative inquiry based on a Constructive and interactive environment. Furthermore, a creative activity- constructing a creative product using building blocks- was presented as an example. Finally, we investigate the pedagogical implications and suggest directions for the further development.

  • Information and communication industry, which shows rapid growth rate, is now leading the global economic growth, contributing a ripple effect on general business and economic structure. It is said that information and communication industry enables swift economic growth taking a role as a basic industry of information-oriented society. Especially, rapid technical innovation promotes mutual growth of other related industries and it is technology-intensive. The purpose of this research is to analyze the management efficiency of information and communication industry using DEA method, and finally suggest numerical value for inefficient organizations to improve their efficiency. CCR-I, BCC-I efficiency and RTS(Returns to scale) of 29 companies engaged in information and communication industry was evaluated. With the results, I suggested model companies for benchmarking in information and communication industry. To summarize, 7 companies were selected with CCR-I efficiency rate 1, and 12 companies with BCC-I efficiency rate 1. RTS was finalized with 8 IRS companies, 10 DRS companies, and 11 CRS companies.

  • 세계 각 국은 현재 스마트 열풍 속에 4차 산업혁명 시대로 변화하고 있다. 교육 또한 e-러닝의 지속적인 성장 발전을 통해 유비쿼터스 환경에 적합한 학습형태인 모바일 기반의 스마트러닝으로 진화하고 있다. 본 연구는 e-Learning 성공요인으로 가장 주목받고 있는 학습자의 동기요인에 관하여 Keller의 ARCS모델에 근거하여 학습자의 스마트러닝 학습성과와 관련된 요인들 간의 관계를 분석하였다. 학습자의 학습 동기 전략 요소가 학습성과에 영향을 미치는 과정 중에 특히 학습자에 대한 여러 동기부여 전략이 학습몰입이라는 매개변수의 조절효과를 거쳐 학습성과에 미치는 영향을 연구 구조모형을 통해 확인해 보았다.

  • Purpose: To find out whether the self-care ability measurement used for visiting health care provide an appropriate standard to select service methods using a Delphi survey and to offer basic data that can improve the measurement. Method: A Delphi survey was done with 39 people consisting of theoretical professionals, field managers, and practitioners engaged in visiting health care. Result: It was found that items and weighted points in the currently used self-care ability measurement needed adjustment. Therefore, a modified evaluation standard was presented by domains, items and detailed items. Finally, the self-care ability measurement is composed of 4 domains, 11 items and 19 detailed items. Conclusion: This study is significant in that it presented an evaluation standard applicable directly to business practice by supplementing problems in the existing self-care ability measurement. This study suggests the need to develop various measurements for elderly households based on community.

  • Most of people who are engaged in research and development find it difficult to solve the engineering problems creatively due to the lack of ideas. There are two famous methods for inventive problem solving' 'Brainstorming' and 'TRIZ'. Brainstorming is the most popular tool until now to find a creative solution and TRIZ is not so popular yet but leads us to a very useful and clear solution. These two methods whose goals are the same usually take quite different routes to the final solution; Those routes have their own unique advantages and disadvantages. In this paper, a creative problem solving method optimized by correlating Brainstorming and TRIZ is proposed. And this method demonstrates how rough initial ideas can be quickly refined and how a problem can be solved correctly.

  • This paper investigates what informal knowledge and strategies fifth-grade students brought to a classroom and how much they had potential to solve fraction division story problems. The findings show that most of the participants were engaged to understand the meaning of fraction division prior to their formal instruction at school. In order to solve the story problems, the informal knowledge related to fractions as well as division was actively utilized in student's strategies and justification. Students also used various informal strategies from mental calculation, direct modeling, to relational thinking. Formal instructions about fraction division at schools can be facilitated for sense-making of this complex fraction division conception by unpacking informal knowledge and thinking they might bring to the classrooms.

  • Recently domestic mobile carriers have been engaged in heated battles for survival as the market is now rapidly approaching its maturity phase. and the launch of 3G service combined with the introduction of mobile number portability is dramatically reshaping the market landscape. The mobile carriers may have to create and maintain their competitive advantage based on their core capabilities and differentiated strategies. which will lead continuous survival and profits of the firm. This paper investigated competitiveness factors among mobile carriers. and analyzed the relationships of firm capabilities. competitive strategies and competitive advantage. We found that core capabilities and competitive strategies affecting competitive advantage are different from each carrier. Finally. we discussed strategic implications for carriers to increase their competitiveness.

  • This paper will introduce and overview in general the $Seongbyeon$ $Deungrok$ issued by the Gwansang-gam, the Astronomical Board in the Joseon Dynasty of Korea. All the Chinese characters in the 1668 $Seongbyeon$ $Deungrok$ was deciphered at first and these were translated into Korean and English. With these translations and the word 'white vapor' in particular we discuss the nature of the main object in this $Deungrok$. Lastly, names of observers who engaged in the observations of this 1668 celestial, which are made as a by-product of this research, are introduced.

  • An online survey was conducted to assess motivations for using, reliance on, and perceived credibility of political blogs and microblogs during both the Taiwanese general election of 2009 (the blog epoch) and the presidential elections of 2012 (the microblog epoch). Results indicated higher reliance on and motivation for using political blogs than microblogs. Blogs were also perceived to be more credible than microblogs. Respondents who primarily engaged in blogging for information purposes were more likely to judge candidate blogs as highly credible, whereas interest in entertainment emerged as the strongest predictor of the perceived credibility of microblogs. This research also provided quantitative evidence showing how users viewed blogs and microblogs differently in the context of political campaigns. The aim is to explore the pros and cons of blogging and microblogging as a tool for political communication.
