There are several researches on 2D gaze tracking techniques for the 2D screen for the Human-Computer Interaction. However, the researches for the gaze-based interaction to the stereo images or contents are not reported. The 3D display techniques are emerging now for the reality service. Moreover, the 3D interaction techniques are much more needed in the 3D contents service environments. This paper addresses gaze-based 3D interaction techniques on stereo display, such as parallax barrier or lenticular stereo display. This paper presents our researches on 3D gaze estimation and gaze-based interaction to stereo display.

이 글의 목적은 게임에서의 상호작용의 특수성에 대한 고찰이다. 여기서 다룰 상호작용성은 사회과학적 상호작용과는 다른, 철학적 맥락에서 이해되어야 할 상호작용성이다. 상호작용의 특수성을 규명하기 위해서는 다음의 절차가 요구된다. 첫째, 상호작용성의 외재적 성격의 검토, 둘째, 상호작용성의 내재적 이해, 셋째, 게이머의 양면성 파악, 넷째, 게이머의 상호작용의 의미해석이다. 이 글의 결론은 다음과 같다. 상호작용의 특수성은 게이머가 처한 이중의 사태를 토대로 기존 관점의 전향을 이끄는 유희적이고 존재론적인 힘으로 나타난다.

웹기반 교육 시스템의 경우 학습자간의 상호작용이 교육적 교류와 사회성을 증진하는데 도움을 주기 때문에 인터넷을 통하여 상호작용을 증진하는 방법이 매우 중요하다. 본 논문에서는 학습자의 상호작용 향상을 위한 웹기반 문제중심학습(PBL) 시스템을 설계 및 구현하였다. 실제 웹기반 PBL 수업에서 설계된 상호작용 증진 방안이 PBL 활동에 어떤 영향을 미치고, 학생들이 웹기반 PBL 학습경험을 어떻게 인식하는지 조사하였다. 실험결과 제안한 시스템이 학습자들의 자기 주도적 학습과 정과 상호작용을 촉진하는 것으로 확인되었다.

This study investigated the effectiveness of teachers inquiry-discovery verbal interaction which was compared with expository-directive verbal interaction. Two teachers from two different kindergarten groups were trained and observed during conversation and science corner activities. Sixty children were observed during science corner activities and tested with a scientific achievement instrument. Teacher's inquiry-discovery verbal interaction had a more positive effect on children's scientific attitudes than teacher's expository-directive verbal interaction. Teacher's inquiry-discovery verbal interaction had a more positive effect on children's scientific achievement than teacher's expository-directive verbal interaction. Children's scientific attitudes and children's scientific achievement had a positive correlation.

The purpose of this study wasto understand Theraplay interaction and to find out how Theraplay works to bring about change in withdrawn children. In exploring the meaning of Theraplay interaction, I used a phenomenology, which looked reflectively into a child's experience. Examining the situation, I found that the child had changed by "touch" with a therapist, which had been done throughout thewhole process of therapy. The child had changed from "child with horny body" to "playful child." Furthermore, I realized the four meanings (of what?) through research: "encounter", "reconstruction", "responsibility", and "immersion." Those four meaningscould have made the subject of interaction go beyond and look for its own existence. In addition, those four meanings melt together in the phenomena of interaction. There were always those four meanings throughout Theraplay interaction. This study has presented different consequences, compared to Theraplay research that is based on effectiveness, and examined the process of change that includes position tendency.

This paper proposes an interaction field concept based on the field theory of plasticity. Relative deformation between two arbitrary scales, e.g., macro and micro fields, is defined which can be implemented in the crystal plasticity-based constitutive framework. Differential geometrical quantities responsible for describing dislocations and defects in the interaction field are obtained, based on which dislocation density and incompatibility tensors are further derived. It is shown that the explicit interaction exists in the curvature or incompatibility tensor field, whereas no interaction in the torsion or dislocation density tensor field. General expressions of the interaction fields over multiple scales with more than three scale levels are derived and implemented into the present constitutive equation.

The theoretical framework of the interaction fields for multiple scales based on field theory is applied to one-dimensional problem mimicking dislocation substructure sensitive intra-granular inhomogeneity evolution under fatigue of Cu-added steels. Three distinct scale levels corresponding respectively to the orders of (A)dislocation substructures, (B)grain size and (C)grain aggregates are set-up based on FE-RKPM (reproducing kernel particle method) based interpolated strain distribution to obtain the incompatibility term in the interaction field. Comparisons between analytical conditions with and without the interaction, and that among different cell size in the scale A are simulated. The effect of interaction field on the B-scale field evolution is extensively examined. Finer and larger fluctuation is demonstrated to be obtained by taking account of the field interactions. Finer cell size exhibits larger field fluctuation whereas the coarse cell size yields negligible interaction effects.

CWR(Continuous Welded Rail) and bridge interaction produce rail force, bridge displacement and rail/bridge relative displacement. Each of these has limitation by many codes. In this paper, analysis of interaction has been carried out by using foreign codes(UIC 774-3 R code of Europe etc.) because there is no code about interaction between rail and bridge in Korea. Recently, railway bridges with CWR has been constructed for structural and economical reasons. When designer plans railway bridges, design a bridge model first and then investigate railway forces and displacement by interaction analysis. If these results go out bounds from limitation, designer plans railway bridges again and again. In this paper, using the parametric study on CWR and railway bridge interaction, railway bridge parameters such as length of bridge span, area of bridge, moment of inertia, stiffness of pier, etc. are presented. It helps preliminary design of railway bridges.

신약을 개발하거나 단백질 구조를 예측하는데 Molecular Mechanics (MM)의 방법을 사용한다. 하지만, MM 만으로는 자연현상에서 일어나는 결과를 정확하게 기술하기 어렵다. 본 연구는 기존의 MM 방법으로는 정확히 예측이 불가능한 비 공유결합 중 하나인 ${\pi}-{\pi}$ interaction을 양자역학 계산을 통해 정확한 예측이 가능한지 보았다. ${\pi}-{\pi}$ interaction 이란 생체 내, 의약 화합물에서 발견되는 결합이기 때문에, 단백질과 결합하는 구조의 예측이 중요하다고 할 수 있다. 본 실험은 ${\pi}-{\pi}$ interaction을 갖는 Sandwich, T shape, 그리고 Parallel displaced 세 가지 모형을 가지고 양자역학 계산을 수행하였다. 양자역학 계산은 DFT의 세가지 함수 M06_2X, M05_2X, B3LYP를 이용하였다. 실험결과에서 세 가지 함수가 각기 다른 결과를 보였는데, M06_2X의 결과에서 ${\pi}-{\pi}$ interaction을 더 정확하게 계산하였다. 이러한 결과를 바탕으로, 양자역학의 방법을 통해 MM에서는 예측이 불가능한 ${\pi}-{\pi}$ interaction을 계산 할 수 있고 이 부분을 고려하여 화합물 간의 결합구조를 예측을 향상시킬 수 있다.

The contiguous or adjacent foundations are always coupled through the soil. Hence their behavior is quite different due to the interaction effects between or among the foundations. The interaction effects can be very pronounced if the distance between them is very close. An 3-D homogeneous strip hyperelement is developed to analyze the dynamic interaction between rectangular or irregular shape found ations. The effects of interaction on the dynamic behaviors of the adjacent rigid rectangular foundations. The effects of interaction on the dynamic behaviors of the adjacent rigid rectangular foundations. The effects of interaction on the dynamic behaviors of the adjacent rigid rectangular foundations resting on the surface of a stratum are stratum are studied using the newly developed method.
