In this study, we proposed Interactive Visualization methods that can be analyzed relations between nations in various viewpoints such as period, issue using total 5211 of the UN General Assembly voting data.For this research, we devised a similarity matrix between nations and developed two visualization method based similarity matrix. The first one is Network Graph Visualization that can be showed relations between nations which participated in the vote of the UN General Assembly like Social Network Graph by year. and the second one is Proximity based Circular Visualization that can be analyzed relations between nations focus on one nation or Changes in voting patterns between nations according to time. This study have a great signification. that's because we proposed Proximity based Circular Visualization methods which merged Line and Circle Graph for network analysis that never tried from other cases of studies that utilize conventional voting data and made it. We also derived co-operatives of each visualization through conducting a comparative experiment for the two visualization. As a research result, we found that Proximity based Circular Visualization can be better analysis each node and Network Graph Visualization can be better analysis patterns for the nations.

Information of social relationship of users on online is useful information for other services such as recommend information of commercial activity. So, there is a lot of studies analysis with connection to visualization of social network. Most of the previous works of visualization focus on representing user's relationship on social network by a complex multi dimension graph. However, this method is difficult to identify the important of relationship to focus on personal user intuitively. In order to resolve above problem, this paper proposes a new visualization method using the user's correlation and user relationship of network node. The proposed method visualizes the hierarchy relationship of users using the internal relation of network reflecting user's message and external relation of network nodes.

Information Visualization is an information technology to visually represent the data and information by utilizing various tools. Visual information can increase the user's intuitiveness and it can be an effective way that can observe and comprehend the specific information in a short time. Information Visualization, as a research method on Humanities, in the high interest of researchers of Humanities and Area studies, is recently used for collecting base data and analyzing information. As an way to use Information Visualization, various forms of Information Visualization like Electronic Cultural Atlas, Network and Multimedia are actively discussed and studied today. In this paper, Information Visualization will be discussed by utilizing D3, a web-based technology for dynamic visualization. In detail, relationship between the Abbasids of Islam can be visualized by using nodes and connection lines and, this relationship between objects will be analyzed efficiently. Researchers related in this field can use this analyzed information for basis data in their researches.

As interpretation of descriptive illustrations without caption differs from each viewer, it is deemed that the effect of attention is represented differently and the acceptance level of any advertisements will be ultimately different according to the visualization method of concept in the creative. The purpose of this research is to recognize the reality and status of visualization for real estate ads in newspapers via visualization analysis through Otto Kleppner's visualization model and to reasonably and efficiently conduct creative of real estate ads by representing problems and their solutions based on the surrey. These activities are to more efficiently produce real estate ads, which occupy a relatively important portion in newspaper ads.

해양오염사고를 표시하는 기존의 방법은 사고의 위치를 점으로 표시하는 방법, 사고의 빈도나 규모를 해도에 영역(Heat map)으로 표시하는 방법, 사고정보를 코드화하여 그래프로 표시하는 방법, 그리고 사고의 위험도를 평가하여 해도에 구획을 정하여 해당 구획의 위험도를 표시하는 방법 등이 해양사고 관련 연구나 분석에 주로 이용되어 왔다. 하지만, 이런 기존의 사고표시방법은 정보를 제한적으로만 표시할 수 있어, 종합적인 사고정보를 전달하기에는 한계가 있다. 따라서, 본 연구에서는 해양오염사고의 정보를 효율적으로 이용 및 전달하기 위해 기름유출사고를 시각화하여 압축적으로 표현할 수 있는 방안에 대하여 연구하였다.

This paper proposes a new visualization method based on Vitualization technique which uses internal relationship of user correlation and external information of social network to visualize user relationship hierarchy. The proposed method use hadoop on virtual machine of OpenStack for distribution and parallel processing which the result of calculation visualizes hierarchy graph to analyze link nodes of Social Network Services for users.

An array DBMS has been expected widely from scientists because it is convenient to store and analyze the data of array type. In this paper, we describe how to handle satellite remote-sensing images in the array DBMS. However, previous works in their visualization have two problems as follows. First, the images are visualized as a state of distorted by the curvature of the earth. Second, it is difficult to apply the results of visualization by pre-written queries to other analyses. Therefore, this paper proposes a three dimensional visualization method of satellite remote-sensing images, not traditional 2D visualization. Our research contents are as follows. First, we describe how to store, process, and analyze the satellite remote-sensing images in the array DBMS. Second, we propose a three-dimensional visualization method for their processed outputs. Lastly, our contributions can be summarized that we propose a method of handling satellite remote-sensing images in the array DBMS and their 3D visualization techniques. It is also expected that their use be available widely in many industrial areas.

This paper deals with visualization that can appropriately show the characteristics deduced from relationships between pieces of information. The visualization of influence, which is used as an important index in deducing the characteristics of relationships in social network analysis, was selected as research topic, and first, the elements that show relationships within the network and the index that show influence were classified and organized. Second, the links between relational elements that show influence in social network were examined, and an influence visualization network was created. Third, an influence visualization framework was proposed which explains the interaction between social network analysis and visualization process. The influence visualization network and framework being proposed in this paper can be used not only to understand and analyze the elements that influence social network but also to make it possible to have a rational and efficient approach to network visualization. Hopefully, they will become a new methodological approach to information design.

본 연구에서는 콘크리트의 균열을 추출하여 추출한 균열을 분석하고 시각화하여 나타내는 방법을 제안한다. 추출한 균열을 분석하여 길이, 넓이, 평균 폭 등의 주요 지표를 측정하여 균열 부위에 대한 세부 정보를 파악할 수 있게 하였다. 특히 균열 분석 과정에서 기존의 균열 중심부와 에지 간의 직선 최단 거리 계산을 통한 균열 폭 측정 방식이 아닌 내접원 탐색 방식을 적용하여 다각형의 균열에 대한 폭 측정 방식을 제안하고 있다. 또한 분석 결과를 Wavefront 3D OBJ 모델과 CAD 파일로 생성하였고, 이를 웹 브라우저를 통해 입체적으로 볼 수 있도록 시각화 하였다.

The main focus of this paper is to analyze trend of event informations in a variety of mass media by graphical visualization in axis of the time and location. Especially, continuity analysis based on user-generated social media can reflect the social impact of a certain event according to change time and location and their directional changes. To reveal the characteristics of continuous events, we survey the data set collected from news articles and tweets during two years. Based on case studies on 'disease' and 'leisure', we verify the effectiveness and usefulness of our proposed method. Even though some events occurred during same period, we showed directional changes which have high-impact in social media referred user interest's, compared with fact-based continuous visualization results.
