Interactive real-time 3D enables users to explore virtual three dimensional environments and also experience contents in an absorbing fashion. Unlike other media, Interactive real-time 3D users take an active role in the process of "real-time fashion" where action and reaction occur instantly in a digital 3D structure. Once the components and origins of interactive real-time 3D is made, it is possible making principles of the beauty that help decide success or failure of real-time 3D in two way system. Substantial real-time 3D has not yet passed 10 years so it was unable to make sufficient precedents of fundamental artistic value based upon the credibility of the media. The goal is to explain the new form of design in relation to general principles of arts at the same time to understand the technical definition better. Concepts of historical documentation are explained with an example of categorization of recent video game and recent technology. This thesis concludes with rough forecast on the future interactive real time 3D. Since the medium began relatively recently and is developing in the rapid pace, recent analyses, though clear forecast is difficult, tend to investigate potential directions to some level the field allows.

In this modern society, the students should be able to recognize problems for themselves, and search the information which is valuable for them, and apply and utilize it. For these, we analyzed the effect of the discussion learning using the concept cartoons on the students' learning attitude and achievement. Even though there was no meaningful difference in the achievement between the experimental group and the control group, it was found that the discussion learning using the concept cartoons could be one of the ways that improve the students' problem solving ability. The fact that there was the significant affirmative effect on the students' positiveness when they were solving the problems was also found.

2010년 초반 이래 지역 해양안보는 보다 개선된 신뢰증진을 위한 안보구도와 메커니즘을 요구하고 있다. 특히 2011년 이래 전문가들은 지역 내 어려운 해양안보 문제들을 주요 현안으로 식별하고 있으며, 아울러 다양한 다루기 힘든 개념 위주의 지역 해양신뢰구축방안들을 제시하고 있었다. 최근 동북아는 다양한 해양분쟁과 갈등으로 점철되고 있으며, 대부분 국가들은 더욱 위험한 상황을 선택하기에 주저하지 않는 위험한 현상을 보이고 있다. 이러한 문제들은 첫째, 기본적으로 기존의 개념적 목적의 해양신뢰구축방안 이행에 대한 실패, 둘째, 개념적 해양신뢰구축방안을 넘어선 기능적이며 실질적 해양신뢰구축으로 변화에 어려움 그리고 셋째, 이를 동북아에서 어떻게 적용30)해야 하는가" 하는 문제로 귀결되고 있다. 대체적으로 전문가들은 개념적 방안 보다 효과적이며 기능적 해양신뢰구축방안을 적용하고 이해하는 것이 바른 "정답"이라고 보고 있다. 따라서 본 논문에서는 기존의 개념적 논쟁에 빠졌던 개념적 해양신뢰구축방안에 대한 과거 미련을 버리고 점차 진화된 복합적 문제로 대두되는 동북아 해양에서의 해양분쟁과 갈등을 기능적이며 실질적 해양 신뢰구축방안에 의해 해결하는 방법을 식별하여 제시하고자 한다. 이에 본 논문에서 제시하는 기술적이며 제도적 해양신뢰구축방안이 인정되면, 지금까지의 작용-반작용의 악순환적 주기를 넘어설 수 있는효과적 해양신뢰 각론, 레짐 또는 거버런스가 될 수 있을 것이다. 궁극적으로 본 논문의 목적은 고질적이고 새로운 해양갈등을 해소할 수 있는 신뢰 구축 전략을 제시하여 지역 해양안전과 평화를 유지하는 것이다.

This thesis will show the preparation of politic alternative plan about reaction through studying the domestic and overseas research trend and theories about online games analyzing the related problems. Online games have been already placed as the major culture trend in our society and produced the economic wealth as the major theme of 'Korean trend hot wind', including improvement of our foreign confidence. And the investments in online games and related industry are expected to be great Blue Ocean to us to have relatively deficient endowed resources. But with these beneficial effects, many unexpected reactions have happened and often published by medias, and they will be expected to be serious. So, it is to establish the united solution system of disputes related to online games which are spread in each law. Through this, we must draw prevention effects and use that as the evidence of rational judgements. And we must make the base to give online games the opportunity of upgrading to national strategic industry and try to conduct the research in various fields between academic organizations.

The information system that preserves and presents information collections, records, processes, retrievals, is applied in various fields recently and is supporting man's many activities. Conventional information systems are based on the reactive interaction model. Such reactive systems respond to only specific instructions, i.e. the defined commands, from the user. To go beyond the reactive interaction, it is necessary that the interactive dynamic interaction based information system which understands human's action and intention autonomously and then provides sensible information adapted to the user. Therefore, we propose a Gaze Mirroring-based intelligent information system for making user's latent interest using the internal state estimation methods based on the interactive dynamic interaction. Then, the proposed Gaze Mirroring method is that an anthropomorphic agent(avatar) actively established the joint attention with the user by imitating user's eye-gaze behavior. We verify that the Gaze Mirroring can elicit the user's behavior reflecting the latent interestand contribute to improving the accuracy of interest estimation. We also have confidence that the Gaze Mirroring promotes the self-awareness of interest. Such a Gaze Mirroring-based intelligent information system also provides suitable information to user by making user's latent interest using the internal state estimation.

The human sense of touch provides us with an important source of information about our surroundings. Because of its unique position at interface between our bodies and the out world, touch sensation supplies sensory data which helps us manipulate and recognize objects and warn of harmful situation. But tactile sensation was recognized less important than visual sense and auditory sense but it plays an important immersing role in virtual reality and computer game. Tactile sensation can be used to influence to objects according to power and supplied sensory feedback to the player in a virtual environment. This paper investigated the characteristics of tactile sensation of human being and proposed method of sturdy using force sensing sensor, simple force modeling and data structure form for virtual reality and computer game. As a result, force distribution, depth, center point can be calculated using sensor output and this information is very effective to specific position for actions and reactions. This study can used as basic information for tactile sensation and it's application in computer game and virtual realty.

The research was conducted with awareness of cultural uniqueness in each country and similarities and universality among countries. On that account, it raised questions about the idea that social well-being can be achieved only materialistic consumption and its cultural symbolism can lead to incongruity in social hierarchy and then dysfunctions in a counter way. On the other hand, the value of well-being can be achieved by many different ways and within one's limited budget as well as material consumption. This paper provides basic information about the development of essential wellbeing products and strategies for building market segmentation in the industry. The research also provides policy makers with the direction of welfare policy in our society to establish a foundation of creating conditions for true well being. This paper will be helpful in fulfilling well-being in our whole society.
