성공적인 창업을 위해서는 창업자 개인의 기본적인 역량뿐만 아니라 체계적인 창업교육과 학습을 통해 창업자가 되기 위한 필요역량을 습득해야 한다(최서윤, 2017). 대학생의 창업을 활성화하기 위해서는 다양한 분야를 전공하고 있는 대학생의 학문적 특성을 고려하고 그들의 전공 및 학문적 특성을 고려하여 창업교육 및 창업지원을 통해 대학생의 창업의지를 높이는 것이 필요하다(이우진 김진수 김용태, 2013). 창업의지는 창업에 대한 행위적 태도를 의미하며, 창업이라는 긴 과정의 첫 단계이고, 개인의 태도와 경험을 창업이라는 행동으로 매개하는 역할을 한다(윤방섭, 2004). 대학이 학생들에게 창업교육 및 창업공간, 멘토링, 컨설팅, 사업화를 위한 창업지원을 하고, 대학생들은 이러한 창업교육 및 창업지원을 긍정적으로 받아들일수록 창업의지가 높아져 취업이 아닌 창업을 선택할 가능성이 높아질 것이다. 조사대상은 전국의 보건계열 대학에 재학 중인 대학생이다. 자료수집 방법은 보건계열 재학 중인 대학생을 대상으로 이메일 설문지가 발송되었고, 자기보고식 작성방법에 따라 설문조사 되었다. 총735개의 설문지가 발송되었고 그 중 불성실하게 응답한 설문을 제외한 총 675개의 설문을 최종 설문으로 사용하였다. 자료수집기간은 2017년 10월 9일부터 2017년 10월 18일까지 10일간 이루어졌다. 본 연구를 수행하기 위해 수집된 자료는 IBM SPSS Statistics 22.0을 활용하여 분석하였다. 본 연구는 보건계열 대학생의 창업가 특성이 창업의지에 영향을 미치는지, 창업교육과 창업지원제도는 기업과 특성과 창업의지의 관계에서 조절효과를 미치는지를 확인하였다. 보건계열대학생의 창업가 특성인 성취욕구, 자기효능감, 위험감수성 중 위험감수성만이 창업의지에 영향을 미치는 것으로 나타났으며, 창업교육, 창업지원제도인 대학창업지원활동, 정부창업지원정책 중 창업가 특성과 창업의지 간의 관계에서 대학창업지원제도만 조절작용을 하는 것으로 나타났다.

In aspect of HCI(Human Computer Interaction) gameplay is the procedure to solve the problem that gamers encounter in order to generate or discover a new rule to achieve gamers' goal. The goal of this research is to investigate the structure and understand the gameplay in aspect of affordance from ecological psychology rather than the traditional problem solving theory. This research selects 'World of Warcraft' as MMORPG(Massively Multiplayer Online Role Playing Game). Five expert gamers participated in this experiment. We record all gameplay using audio and video device. We conducted protocol analysis as qualitative method based on the verbal report and action protocol during game playing. As result, gameplay based on affordance includes selection and relation. We found that subjects selected one thing at once with attention. Moreover, we found that there were two behaviors : exploratory action and performatory action. We believe that learning, utilization, and transformation for affordance appear. The result of this research imply to suggest design guideline for game design methodology when designers develop game.

In 2009 revision and 2015 revision mathematics national curriculum, 'proof' was moved to high school from middle school in consideration of the cognitive development level of students, and 'proof by contradiction' was stated in the "success criteria of learning contents" of the first year high school subject while it had been not officially introduced in $7^{th}$ and 2007 revision national curriculum. Proof by contradiction is known that it induces a cognitive conflict due to the unique nature of rather assuming the opposite of the statement for proving it. In this article, based on the logical, mathematical and historical analysis of Proof by contradiction, we looked about the introductions and the applications of the current textbooks which had been revised recently, and searched for improvement measures from the viewpoint of discovery, explanation, and consilience. We suggested introducing Proof by contradiction after describing the discovery process earlier, separately but organically describing parts necessary to assume the opposite and parts not necessary, disclosing the relationships with proof by contrapositive, and using the viewpoint of consilience.

This article provides how to implement the use of Realistic Mathematics Education (RME) in a teaching a function at a school to improve students' mathematization for their mathematical thinking using technology, This study was planed to get research results using the mixed methodology with quantitative and qualitative methodologies. 120 middle school students participated in the study to bring us data about their mathematical achievement and disposition. Through the data analysis used ANCOVA, the students with the experiment of the mathematization and technology excelled the other groups of students who were not provided with technology or both of them. In analysis of the questions of the achievement test, the problems for vertical mathematization were presented harder for the students than the other problems for horizontal and applicative mathematization. The technology environment might have helped students manipulate the application of real-life problems easier. This means that teachers can put more careful assignment on vertical mathematization using technology. We also explored that learning and teaching under RME using technology encouraged students to refine and develop their informal functional concept and pursue higher thinking of formalization. The study results in a lot of resources for teachers to use into their teaching mathematics for improving students' mathematical thinking.
