Recently, Product and contents using virtual reality technique is spreading quickly. Visualization using virtual reality technique is provide a differentiated experience with existing visualization methodology by giving enhanced immersiveness to users. This paper is make a suggestion to a new methodology of stereo-scope visualization and talk about this utilization possibility. We proposed the design method of stereo-scope realization system that is composed at least two screen. through which users will feel more immersiveness and experience to virtual reality. The suggestion system of this paper will widely used in various industry such as virtual reality exhibitions, shows, games, training programs, etc.

Text visualization is one of sectors in data visualization. This study is on methods to visually represent text's contents, structure, and form aspects based on various analytic techniques about wide range of text data. In this study -as a text visualization study-, 1) a method to find out the characteristics of a book's genre using words in the text of the book was looked into, 2) elements of visualization of a book's genre based on verification through an experiment were drew, and 3) the ways to intuitionally and efficiently visualize this were explained. According to visualization suggested by this study, first, actual genre of a book can be understood based on words used in the book. Second, with which genre is closed to the book can be found out with one glance through images of visualization. Moreover, the characteristics of complicated genres included in a book can be understood. Furthermore, the level of closeness (similarity) of a genre -which is found to be a representative genre using the number of dots, curvature of a curve, and brightness in the image- can be assumed. Finally, the outcome of this study can be used for a variety of fields including book customizing service such as a book recommendation system that provides images of personal preference books or genres through application of books favored by individual customers.

In this study, an unplugged education method which focuses on the data visualization training was applied to third grade students of an elementary school and analyzed its impact on enhancing their computational thinking. The analysis was conducted on 60 elementary school teachers and 124 third grade students and the unplugged education program based on the data visualization procedure was developed. The education program developed was carried out with 24 third grade students for 36 hours over six days. The effect of the program applied was analyzed through the pre-to-post comparison performed with perceptive strength test and creativity test in order to examine the enhancement in computational thinking. According to the analysis result, the unplugged education method which focuses on the data visualization training has significant effect on the 'computational perception' and 'creativity' of third grade students.

With the development of smartphones and wearable devices, researches related to platforms that collect lifelogs from these devices and the visualization of the lifelog results have also been advanced. However, the existed researches were impossible to collect data from various devices because they depended on a specific device and platform when transmitting or receiving lifelog data. In addition, they do not provide visualized analysis results of specialized lifelogs in specific areas, such as the users' location information. To resolve the problems, this paper analyzes user location information from the lifelog collection platform and develops the interface and visualization tools for lifelog collection. To do this, we define and analyze the requirements of developing the proposed system. Then, based on the analyzed requirements, this paper develops a lifelog visualization tool using various graphs, maps and the RESTful API interface and shows its implemented results.

도시 소음이 미치는 경제적, 사회적 영향이 커짐에 따라 최근 도시소음에 대한 관심이 높아지고 있다. 그러나 기존의 2차원 소음지도를 통해서는 점점 복잡해지고 대규모화 되어 가는 건물의 각 공간에 대한 소음분석 및 시각화에 한계가 있다. 따라서 본 연구에서는 소음데이터의 3차원 시각화 및 공간별 소음분석을 위해 토폴로지가 부여된 3차원 GIS 데이터 모델을 제시하였다. 건물의 각 공간을 볼륨과 벽체들로 구성하고 공간간의 토폴로지를 부여하기 위해 DB에서 관계를 정의해주고 DB의 볼륨테이블과 벽체테이블에 저장된 소음데이터를 이용하여 3차원 소음분석 및 시각화가 가능하도록 하였다.

Information and Communication Technology environment has been developing rapidly and variety of services are in service. As data becomes increasingly sophisticated. These data was applied techniques of visualization in order to visualize efficiently. Various agencies are providing the map based data in real-time. However, traffic information is getting more complex and users are having a difficulty to understand with convential visualization techniques. This study was designed and implemented in the web service of traffic information using Focus+Context. Web service implemented HTML5(Hyper Text Markup Language 5), and it runs on browser of either desktop or mobile devices. This study sets an example as web application from a user perspective by combining information visualization and traffic information.

네트워크 보안 상황인지 기술이란 현재 네트워크에서 보안과 관련하여 무슨 일이 발생하고 있는 지를 관리자에게 인지시켜 주는 기술이다. 이는 침입탐지시스템이나 방화벽에서 수행하는 잠재적인 공격자의 패킷을 필터링하거나 보고하는 것과는 달리 현재 네트워크에서 발생하고 있는 상황(침입 또는 공격 등)을 알려주는 것에 초점을 맞춘다. 네트워크 보안 상황인지 기술에는 데이터 선정 및 수집, 특성 인자 추출, 연관성 분석, 데이터마이닝, 패턴분석, 이벤트시각화 등과 같이 매우 다양한 세부 기술들이 있지만, 본 고에서는 이벤트 종류에 따른 시각화 기술들의 현황과 ETRI에서 개발한 Visual Scope에 대해 살펴보고자 한다.

Visual analysis of spatiotemporal data has focused on a variety of techniques for analyzing and exploring the data. The goal of these techniques is to explore the spatiotemporal data using time information, discover patterns in the data, and analyze spatiotemporal data. The overall trend flow patterns help users analyze geo-referenced temporal events. However, it is difficult to extract and visualize overall trend flow patterns using data that has no trajectory information for movements. In order to visualize overall trend flow patterns, in this paper, we estimate continuous distributions of discrete events over time using KDE, and we extract vector fields from the continuous distributions using the gravity model. We then apply our technique on twitter data to validate techniques.

최근 기후변화로 인한 태풍과 폭우로 인한 피해가 증가하고 있다. 또한 대피소에 대한 시각화된 정보를 제공하는 애플리케이션이 부족한 실정이다. 본 논문에서는 대피소 정보를 제공하는 애플리케이션을 제안하였다. 제안 애플리케이션은 공공 데이터 포털에서 제공하는 데이터를 활용해 React-Native-Maps 에서 제공하는 마커 기능을 사용하고 구글에서 제공하는 지도 서비스와 결합해 대피소의 위치를 표시한다. 부가적인 특징으로 과거 재난 정보를 시각화 하여 제공하여 피해가 예상되는 지역의 대피소 정보를 동시에 제공하였다. 프로토 타입으로 제작된 애플리케이션을 통해 이후 피해 예상지역을 예측하는데 도움을 줄 수 있을 것으로 사료된다.

The paper starts off with a notion that the most realistic problem in restoring cultural contents' archetype and developing contents industry based on it is the lack of understanding and production about key visual. Thus, with the premise that, in visualizing ancient fantasy as an original archetype subject material, one has to take into account design process for an actual content production, the paper aims for the suggestion of the necessity of key visual through visualization. For this, the paper made an artwork of archetype image based on literature and historical data with which to visualize fantasy elements of Goguryeo's ancient myth and tales that have high utilization value as various subject matters, such as animation and games.
