In this research, based on the fact that spatial ability is important for the achievement in the STEM fields, and technological innovation, Purdue Spatial Visualization Test-Rotation has been used to investigate engineering freshmen's spatial ability and gender differences. Students who have taken advanced mathematics courses in high school(those who have taken type B math test in Korean SAT test) and students with general math courses(those who have taken type A in Korean SAT-Math test) are included in this study to find out the relationship between mathematics achievement and spatial ability. Finding out the strategies taken by students was another aim of this study. This strategic differences between high achievers and lower achievers, male and female students were analyzed from students' self report. Spatial ability test score was highest in the SAT-Math type B male students, decreased in the order of type A male students, type B female students, and lastly type A female students. There was no substantial difference between second and third groups. In each group, male students' average score was 8~10% higher than female students, which affirms 2015's results. The correlation between spatial ability and mathematics achievement was negligible in each group, but male students' math score and spatial ability score were higher than that of female students. This can be interpreted that there is some correlation between these two. Strategic choices can vary in the continuous spectrum with analytic method and holistic method at both ends. From students' self report, using Mann-Witney test, it turned out that there exists strategic differences between male and female students. Male students have a tendency to use holistic strategy more often than female students. I also found that the strategy choice did not vary greatly among all score groups. For the perfect score groups, both female and male students used holistic strategy most frequently. For low achieving groups, there is an evidence that these students overuse one method compared to average or high achieving groups, which turned out to be less effective. Based on these, I suggest that low achieving students need to have more chances to adopt efficient strategies and to practice challenging problems to improve their spatial abilities.

Conventionally, scientific data visualization is thought of as one of activities performed by scientists during the scientific data analysis. However, recently, there exits a set of research papers which count scientific data visualization as a independent research area. They show the research subjects for studying the scientific data visualization technology and methods. In case, a scientist or group of scientists can not solve their own visualization problem due to the unskillfulness and inexperience on using visualization tool. Therefore, it needs to help them by the systematic way for solving the problem. In this study, we analyze and propose the national level scientific visualization support system for scientists. In particular, we first analyze the existing papers and find out the critical success factors. Then, by integrating the findings of the analysis, we propose the research areas which need to be focused, and the strategic direction and specific research topics for scientific data visualization support system in national level.

Flipped learning can be used as an innovative teaching method in science education. This study analyzes video clip produced by pre-service elementary school teachers for flipped learning and explore strategies to organize effective visualization. The pre-service elementary school teachers focused on providing information on macroscopic natural phenomenon using concrete case selection strategy for earth science class. They used marker and spatial transformation elements effectively, but their efforts to link the elements to the experience of students were not sufficient. In addition, it was very rare to put the contents into simplified drawing or provide extreme cases to enhance the imagery of students. In addition, it is necessary to provide specific case of multi-modal and link the material to the experience of students closely through familiar cases or analogical model to establish an effective visual teaching material. It may also be needed to present simplified drawing for enhancing imagery and provide extreme cases to make students have an opportunity to infer a new situation.

특허 데이터 정보는 경쟁자 모니터링, 기술 평가, R&D 포트폴리오 관리 등 전략적 계획의 여러 목적으로 사용되고 있다. 특정 분야의 기술 구조를 시각화하기 위한 방법론으로 특허를 사용한 기술 지도를 2차원상에 표현하는 co-word 분석법이 이용되고 있으나, 이 방법론을 적용하여 기업이 가진 특허를 지도로 시각화하고 분석을 시도한 연구는 없었으며 특허 포트폴리오는 전체 기술을 시각화하는 데 많은 한계를 가지고 있다. 본 연구에서는 특정 기업의 일부 분야 특허에 대하여 co-word matrix를 작성하고 기술을 클러스터링하여 다차원 축적 기법(Muitidimensional Scaling)으로 기술 지도를 작성하였다. 또한, 두 경쟁기업의 기술지도를 비교하여 기업간의 cross-licensing 가능 영역을 보이고 시간 흐름에 따른 기업 기술의 동적 분석 등 다양한 분석방법을 제시하였다.

SP(sales promotion)전략을 지향하는 백화점은 강 한 개성으로 다양하게 변화해 가는 소비자의 욕구충 족을 위해 대 고객차원의 편의성 및 쾌적한 쇼핑환 경을 마련하며 아이디어는 항상 특별하고 새로워야 한다. SP 전략으로서의 VMD (visual merchandi sing)는 상품의 시각화계획 등 통일된 시각(visual identity) 연 출을 통해 고객의 그룹이나 개인의 취향에 맞는 타켓 마케팅 (target marketing) 으로 백 화점 은 고객 의 중심에서 그들의 삶을 윤태하게 하며 아름답고 즐거 운 소비문화를 주도해갈 수 있는 환경을 제공해야 할 것이다. 1999년 말 IMF 이후 최근 막강한 자금력과 경쟁 력을 가진 대형 외국 할인 업체의 부상과 계속되는 장기적인 경제위축으로 백화점의 마케팅활동은 기존 고객과 관련된 단기적 욕구만을 충족시키는 점에서 벗어날 수 없었다. 이렇게 심각한 경기불안과 유통환 경의 급변으로 인해 소비자의 구매력이 약화되고 매 출이 감소하는 등 백화점의 한계성과 업태간의 경쟁 이 심화되어 갈수록 진정한 서비스개념의 합리적 목 적을 띤 VMD가 SP전략의 실질적인 형태로써 존재 되어야 한다. VMD는 이러한 불경기에 대응하는 백화점의 생존 고용식 전략으로서 좀더 강하고 적극적인 글로벌 마인드 ( (global mind)를 갖고 보다 넓은 시장에 대한 장기적 안목을 필요로 한다. 특히 대 고객 감성의 글로벌화 로 광범위한 상품의 장르와 감각적인 투자로써 신 고객창출을 도모하는 한편 고객에 대한 세심한 배려 와 구체화된 전략을 통해 불황을 극복하는 등 국내 유통문화의 선진화를 가속시켜 나갈 수 있는 것이다. "손쉬운 장사벌이"라는 무책임한 사고를 버리고 철저한 고객친화의 중심에 서서 그들에게 즐거웅을 주고 풍요로운 문화의 장(場)을 마련하는 등 지금의 무한경쟁 시대에 가장 감성적인 경쟁력으로서 고객에게는 쇼핑을 통한 즐거움과 여유로움, 풍성한 정보 와 화제성, 독특한 서비스와 볼거리 등이 지속적으로 제공되어야 하며 상품의 시각화 계획인 VMD는 세 련된 드라마처럼 감동적 연출로 그 이야기가 전개되 어야한다. 고객의 구매행동을 기초로 유통시장의 무한 자유 경쟁이란 현 시점에서 판매촉진의 전략에 대한 체계 적 접근과 합목적성을 가진 VMD의 전개 방향 및 향후 백화점업계의 차별화 방안과 전략은 단순한 행 위의 출발이 아닌 주변환경과의 밀접한 연관 속에서 지극히 창조적인 예술적 자극이 요구되며 그 과정에 따른 결과적인 "반응"을 기대한다.quot;반응"을 기대한다.기대한다.

The reason why today's public actively uses social communication is that the necessary information is collected and classified under the name of social big data through the web space to create the big data era, an ecosystem of information. In order for big data information to be used by the public, it is necessary to visualize it easily. This study categorized the types of visualization according to the information of social big data, and targeted the experienced students including the related majors and the general public who need to directly utilize and study the actual big data visualization as an experience evaluation target. As a result of analyzing the experiences of the experienced people, important implications for the visualization method for managing, analyzing, and utilizing the data were derived. The big data visualization strategy is to be expressed in a way that fits the data environment and user's eye level on SNS. In the future, if big data visualization is applied to product service or social trend, it will be an important data in terms of broadening its role, scope of application, and application.
