The purpose of this study was to investigate the relationships between thinking styles and the components of mathematical ability of elementary math gifted children. The results of this study were as follows: First, there were differences in thinking styles: The gifted students prefer legislative, judical, hierarchic, global, internal and liberal thinking styles. General students prefer oligarchic and conservative thinking styles. Second, there were differences in components of mathematical ability: The gifted students scored high in all sections. And if when they scored high in one section, then they most likely scored high in the other sections as well. But the spacial related lowly to the generalization and memorization. There is no significant relationship between memorization and calculation Third, there was a correlation between thinking styles and components of mathematical ability: Some thinking styles were related to components of mathematical ability. In functions of thinking styles, legislative style have higher effect on calculation. And executive, judical styles related negatively to the inference ability. In forms of thinking styles monarchic style had higher effect on space ability, hierarchic style had higher effect on calculation. Monarchic, hierarchic styles related negatively to inference ability. In level of thinking styles global, local styles have higher effect on calculation. Local styles related negatively to the inference ability. In the scope of thinking styles, internal style had a higher effect on generalization, and external style had a higher effect on calculation. And there is no significant relationship leaning of thinking styles.

The purpose of the study is to examine how effects of activities using Google SketchUp on students' spatial ability and 3D geometric thinking in measuring the volume of solid figures. By comparing the results from pre- and post-tests between the experimental group and control group, we found that activities using Google SketchUp help students improve their spatial ability in the spatial orientation and visualization. In addition, more than half students in the experimental group moved from level 4 up to level 7 in thinking process of measuring the volume in terms of Battista(2004)'s levels. This study suggests that the instruction with Google SketchUp can help to improve students' spatial ability and 3D geometric thinking in the regular class in middle school. In addition, SketchUp can be an advanced technological tool to support students' self-directed learning, which create an efficient educational environment and a great opportunity to learn geometry in an effective manner.

Walking is one of human functions and has been the base of the development of human civilization. Walking ability had made the first village and urban pattern of the mankind. Cities had been constructed for pedestrian's convenience and happy life. But conventional cities have been crowded by the rapid increasing vehicles and population since material civilization had developed. On the other hand, pedestrian space has been neglected urban districts. Chose this study to suggest a direction for improvement by following the direction of the city characteristics and roadside pedestrian space. 1. Investigate the relationship and the significance and problems of pedestrian space by finding survey of the literature and discussion with those that affect the behavior of the pedestrian environment around. 2. For a comfortable pedestrian space on the improvement of the pedestrian area of space (physical and psychological) and gait characteristics, service levels and basic data. 3. Chose how to extract the most appropriate of the best alternatives presented several proposals based on the above survey of the literature data and field survey.

The off-screen space openness of the movies converted a unilateral communication, which films have made audiences understand with, into an interactive communication. When the spectators see a movie, the off-screen space will be able to take out their positivity and induce their deep thinking. They won't accept information of the screen by manual operation but will participate in the narrative stories of the cinemas, thinking about the reality. In the paper, it shows that the motion pictures, which Jean Renoir and Michelangelo Antonioni produced, consist of the expressive forms of the off-screen space as well as a human has the ability sense, feeling, perception and memory associated with interacting between the off-screen space and audiences.

공중공간은 평면에 비해 넓고 많은 항공기들이 고속으로 비행하고 있다. 더불어 항공사고는 바로 대형사고로 이어지므로 공중상황 통제의 중요성은 항상 강조되고 있다. 그러나 항공기는 3차원 공간에서 복잡한 패턴으로 비행하기 때문에 통제하기가 매우 어렵다. 통제를 위한 공중상황 정보는 시각화 시스템을 통해 제공되고 있으나, 이를 운영하는 통제요원의 경험, 인지능력이 공중상황판단의 결정적 역할을 하고 있다. 그래서 정확한 상황판단을 위한 정보제공이 매우 중요하다. 본 논문에서는 공중상황에 대한 정확한 정보제공을 위해 비행경로를 이용한 시각화 기법을 제안한다. 대부분의 항공기는 정지하지 않고, 급격한 상태전이 없이 이동하므로 과거 비행자료를 통해 미래의 비행상태를 예측할 수 있다. 즉 과거 상태정보와 현재 상황정보를 통합하여 시각화하면 비행패턴을 예측할 수 있어 정확한 공중상황 판단이 가능하다. 이를 위해 실시간 자료를 분석하여 동적자료를 구분한다. 동적자료만으로 상태전이자료를 생성하고 비행경로 상에서 색상과 도형 및 기호화를 통해 시각화한다. 비행경로와 색상 및 기호화로 제공된 상태전이 시각화 정보는 항공기의 상승/하강, 가속/감속, 직진/선회, 기타 상태전이정보와 바람의 방향과 같은 공중 공간의 상황정보 둥을 제공할 것이다. 이를 통해 운용요원은 공중상황을 정확히 인식하고 신속하게 판다하여 통제함으로서 공중안전을 도모하고 통제업무를 효과적으로 수행할 수 있을 것이다.

지금까지 교통사고 예방을 위한 도로 정보 등을 제공하기 위해 차량 간 통신 네트워크인 Vehicular Ad hoc NETwork (VANET)연구가 활발히 진행되어왔다. 그러나 각 자동차의 On board unit (OBU)의 계산 능력, 저장 공간 등을 효율적으로 사용하는 연구는 진행되어 오지 않았다. 2011년 Olariu et al. 가 cloud computing을 기존의 VANET에 적용하는 개념인 Autonomous Vehicular cloud[1]를 제시하면서 새로운 VANET 연구의 새로운 장을 열었다. 기존의 VANET연구는 지금까지의 각각의 자동차의 통신 성능을 높이는 것에 초점을 맞추었지만, 새로운 아이디어는 높아진 각 자동차의 능력을 효율적으로 이용하여, 유용하게 사용하는 것에 초점을 맞추었다. 이것은 Intelligent Transport System (ITS)의 구축에 한발 더 나아갈 수 있게 하였다. 그 이후 VANET cloud computing (VCC)에 관한 많은 연구들이 진행되었으나 보안적인 측면에서는 아직 연구가 미흡한 실정이다. 그래서 본 논문에서는 보안을 보완한 VCC 아키텍처를 제안한다.
