본 연구는 비트코인 가격 변화량에 영향을 미치는 요인에 대한 실증 분석을 수행하였다. 기존 연구들은 암호화폐와 관련해 블록체인 시스템의 보안성, 암호화폐가 불러일으키는 경제적 파급효과 및 법적 시사점, 소비자 수용 및 사용 의도와 사회현상을 중심으로 이루어졌다. 그러나 암호화폐 가격 변화가 급등과 급락을 반복하면서 많은 사회적 문제를 야기했음에도 불구하고 암호화폐의 가격 변화에 영향을 미치는 요인에 대한 실증적 연구는 부족하다. 때문에 본 연구에서 암호화폐 가격 변화에 미치는 영향 요인을 도출하기 위해 암호화폐 중 가장 대표적인 비트코인을 중심으로 분석을 진행하였다. 분석을 위해 소비자, 산업, 거시경제 세 가지 차원에서 가설을 수립, 각 차원의 변수에 대한 시계열 데이터를 수집하였다. 단위근 검정을 통해 시계열 데이터에 대한 가성 회귀를 제거하고 안정성을 검증한 후, 비트코인 가격 변화량에 영향을 미칠 수 있는 요인들에 대한 회귀 분석을 실시하였다. 분석 결과 비트코인 가격 변화량은 비트코인 거래 금지에 대한 검색 트래픽, 미국 달러지수 변화량과는 음의 상관관계를, GPU 벤더의 주가 변화량, 원유 가격 변화량과는 양의 상관관계를 갖는 것을 확인했다. 그 이유로는 비트코인 거래 금지는 비트코인 존폐와 관련해 투자심리에 부정적 영향을 미친 것으로 판단되며, GPU 벤더 주가는 비트코인 생산 단가 증가와 관련해 비트코인 가격에 영향을 미친 것으로 해석된다. 미국 달러지수와는 반대로 움직임으로서 비트코인이 금의 성격을 갖고 있음을 확인하였으며, 원유 가격과의 관계를 통해 원자재와 같은 투자 자산의 역할도 갖고 있음을 확인하였다. 본 연구의 결과를 통해 비트코인이 가진 성격을 규명하였으며, 비트코인 가격 변화 요인에 대한 실증 검증을 통해, 그 동안 부족했던 비트코인 가격 변화 요인을 규명하였고, 해당 요인들을 통해 실무적으로 소비자나 금융기관, 정부 기관에 대해 비트코인에 대한 전략적인 접근방법에 대한 가이드를 제공할 수 있다는 점에서 의의가 있다.

I wish to search for educational alternatives which improve students' mathematical creativity. As the first attempt for this, theories of general creativity and characters of mathematical creativity are discussed. And four factors( teacher variables. student variables, teaching and learning variables. environment variables) affecting mathematical creativity are analyzed. It is a educational well-known fact that students should think creatively and solve the problems for themselves. We postulate the fact that students' mathematical creativity can be developed. I think it is a mission and a duty for mathematics educators to develop the students' mathematical creativity fully. Mathematics educators should search for the methods which encourage the students to have mathematical creativity and should develop them.

The purpose of this study was to identify the variables which could characteristics the New Young Generation (NYG), to investigate the relationship between level of NYG characteristics and information searching related to underwear purchasing, and the differences level of the NYG characteristics according to demographic variables (sex, grade, major), and examine the casual relationships of demographic variables (sex, place of growing background, parent's education) and level of the NYG characteristics on information searching related to underwear purchasing. The subjects were 723 college students (female = 324, male=398) living in Seoul and Kyuggi were participated in this study. The NYG is limited to person who born after 1970's. The result of this study were as follows; 1. Five factors of New Young Generation oriented characteristics were identified; F.1 'Info-telecommunication(Info-Telecom)'; F.2 'Family and Marriage'; F.3 'Consumption pattern'; FA 'Self-centered (Individualism)'; F.5 Work/Career oriented. 2. The relationship between the NYG characteristics and information search in underwear purchasing were significanted. 3. In demographic variables, gender, grade, and major were partially significant differences. 4. In male students, the result of the casual relationship between demographic variables with NYG characteristics and the level of the NYG in underwear purchasing showed that grade, background of grownplace, level of parent's education were significanted the high level of info-telecom factor associated with higher grade, city-grown, higher level of parent's education. In conclusion, the result showed that the level of NYG characteristics was significant to male students and specially for grade older students. The background of parent's education level was the another important variables to predicting the NYG characteristics. Finally the higher the NYG characteristics, the more information search in underwear purchasing.
