최근 디지털 데이터가 폭발적으로 증가함에 따라 빅데이터, 데이터시각화, 정보시각화, 인포그래픽 등에 각종 언론매체 및 기관에서 관심을 기울이고 있다. 국내에서는 조선닷컴, 한겨레 신문 온라인판 등에서 데이터 시각화 및 인포그래픽을 선도적으로 다루고 있으며, 국외에서는 영국의 가디언, 월스트리트저널, 뉴욕타임즈 등에서 데이터 시각화 분야에서 두각을 나타내고 있다. 우리나라의 경우 데이터시각화 분야는 아직까지 디자인적인 측면에 중점을 두고 있다. 그러나 최근 주목받고 있는 데이터시각화 프로그램 중 Tableau Public 프로그램을 이용하면 좀 더 효율적인 인포그래픽을 제작할 수 있다. 본 연구에서는 Tableau Public을 통해 데이터 분석 및 인포그래픽을 제작하였다. 인포그래픽 제작을 위해 세계은행 데이터가 사용되었으며, 전세계자동차보유율을 분석하여 두 가지 결과가 도출되었다. 첫째, 고소득국가 그룹에서는 1인당 국민총소득이 증가할수록 기울기는 감소추세를 보였고, 중위소득국가에서는 증가추세를 보였다. 둘째, 기준기간에 비해 금융위기 기간에는 1인당 국민총소득 증가율에 따른 전년대비 자동차보유율 증가율이 1.7배 높게 나타났다. 본 논문에서는 Tableau Public을 이용한 데이터 시각화 사례연구를 통해, 기존 디자인 중심의 인포그래픽 제작환경에서, 향후 데이터 중심의 인포그래픽 제작 설계를 활성화시키고자 하였다. 그리고 더 나아가 데이터 중심의 인포그래픽은 과학적 연구, 그리고 정책결정을 위한 도구로써 널리 이용되어야 할 것이다.

하루가 다르게 방대한 데이터가 생겨나고, 데이터를 반영한 정책지원이나 콘텐츠들이 증가하면서 데이터에 대한 중요성이 주목받고 있다. 데이터의 시각화 측면에서 모든 데이터를 살펴보는 것에 제약이 따르기 때문에, 시각화의 기술적인 요소뿐만 아니라 데이터를 요약하고, 이해하기 쉽도록 돕는 시각화의 방법론적 요소가 중요하다고 할 수 있다. 본 논문에서는 현재 많이 사용되는 디자인 중심의 인포그래픽을 개선하고 데이터 중심의 인포그래픽을 제안하기 위해 데이터 시각화의 표현 방법을 정리하고, 시각화의 방법을 Tableau Public을 활용하여 데이터 분석 및 인포그래픽 제작사례를 제시고자 한다. 인포그래픽 제작을 위해 광주광역시 버스 이용자 데이터가 사용되었고, 분석결과 정류소 사용 총 승객수는 일반 승객수와는 유사한 결과를 보이지만 환승역 이용 승객, 청소년 승차 환승 승객수에 따른 정류소와는 차이를 보였다. 그래프 유형에 따라 시각적인 결과는 다르게 도출되었다. 데이터 중심의 인포그래픽 시각화는 기존의 인포그래픽의 시각적인 역할만 강조한 것에 비해 데이터를 효율적으로 전달하는 것을 물론 과학적 연구를 위한 도구로 활용될 것으로 기대한다.

This study is to explore the airline network patterns of Incheon and Narita International Airports using passenger flight departure and arrival data of the two airports. The so-called Origin-Destination data is collected from the airports' websites and some of the important data items are flight number, city of origin, destination city, departure/arrival time, number of flights, and delay time. A snowflake schema dimensional model is proposed and implemented. Tableau Public, a well-known visual analytic tool, is used to connect the dimensional model and played an important role in navigating the data space to find interesting and visual patterns among corresponding airports and airlines. For the efficiency of analyzing this spacious data mart, data visualization method was used. Four types of visualization method proposed by Yau was used; visualizing patterns over time, visualizing proportions, visualizing relationships, and visualizing spatial relationships. The strength of connectivity of each flight segments is calculated to evaluate the degree of globalization of Seoul and Tokyo. We anticipate that various patterns and new findings produced by the data mart would provide airline managers, airport authorities, and policy makers in the field of travel and transportation with insightful information.

Visual analytics is an emerging research field that combines the strength of electronic data processing and human intuition-based social background knowledge. This study demonstrates useful visual analytics with Tableau in conjunction with semantic network analysis using examples of sentiment flow and strategic communication strategies via Twitter in a blockchain domain. We comparatively investigated the sentiment flow over time and language usage patterns between companies with a good reputation and firms with a poor reputation. In addition, this study explored the relations between reputation and marketing communication strategies. We found that cryptocurrency firms more actively produced information when there was an increased public demand and increased transactions and when the coins' prices were high. Emotional language strategies on social media did not affect cryptocurrencies' reputations. The pattern in semantic representations of keywords was similar between companies with a good reputation and firms with a poor reputation. However, the reputable firms communicated on a wide range of topics and used more culturally focused strategies, and took more advantages of social media marketing by expanding their outreach to other social media networks. The visual big data analytics provides insights into business intelligence that helps informed policies.

Since trees in the city are green assets that create a healthy environment for the city, systematic management of trees improves urban ecosystem services. The sporadic urban tree information centered on the site is vast, and it is difficult to manage the data, so efforts to increase efficiency are needed. This paper summarizes tree data inventory based on data constructed by Seoul Green Trust activists and constructs and discloses online database maps using Tableau Software. In order to verify the utilization of the map, we divided into consumer and supplier aspects to collect various opinions and reflect feedback to implement tree database maps for each area and species of Seoul Forest. As a result, the utilization value of tree database in urban parks was presented. The technical significance of this study is to systematically record the process of constructing and implementing a dashboard directly using the Mapbox platform and Tableau Software in the field of landscaping for the first time in Korea. In addition, the implications and supplements of landscape information were derived by collecting user opinions on the results. This can be used as an exploratory basis in the process of developing online-based services such as web and apps by utilizing landscaping tree information in the future. Although the visualization database currently constructed has limitations that ordinary users cannot interact in both directions because it utilizes business intelligence tools in terms of service provision it has affirmed both the database construction and its usability in web public format. In the future it is essential to investigate the assets of the trees in the city park and to build a database as a public asset of the city. The survey participants positively recognized that information is intuitively presented based on the map and responded that it is necessary to provide information on the overall urban assets such as small parks and roadside trees by using open source maps in the future.

"Printing is an Art of reproduction & a Technique of However printing has extended its limitation from a genre of reproduction itself and now it stands on the turning point as an art such as painting or sculpture which expresses artist's originality. Early Printing has had relations in depth with press printing in terms of information recording, preservation, and transmission. It was acknowledged value in a way of information satisfaction different from how it is valued as a pure art today. But, later printing has transferred its function from a mean of reproduction to pure art due to the development of printing skills and photography invention. It can be said that the concept of modern printing is taking over its genealogy as a creative work not as just printing. Also its expression capability is widen to dimensional printing and high-tech multimedia from original tradition techniques. As we discussed above, modern painting is very open to various changes. This modern painting aspect can be seen as an extended interpretation of 'board' concept. This dissertation raises a question why monotype and monoprint couldn't secure its position in printing history in spite of numerous artists' tryouts in its way. Monotype and monoprint fundamentally based on intaglio technique in its history. Yet, its systematic study hasn't been worked out. This is because of the lack of recognition of monotype and monoprint's originality as printing. Especially in monoprint, it has known as an early stage in copperplate printing process which is an attempt to solve the technique limitation or trial work for edition. Likewise the reason why monotype and monoprint remains at the edge of printing border ambiguously is because of conceptual, technical characteristics which are against traditional printing. In traditional printing, the concept of board is important as a method of reproduction. Different from the fact, monotype and monoprint accept the form of medium 'board' conceptually out of limited condition as mentioned. Thus monotype and monoprint hasn't stand out for several reasons until late 20th century when it started come out to public as people starts to have interests that works from famous artists are actually based on monotype and monoprint. This dissertation likes to step into the monotype and monoprint theoretically which is not well known in domestic and try to study the meaning of monotype and monoprint as a printing medium which is also hasn't been considered sincerely. For this study the process follow as below. First, look into how monotype and monoprint has a concept and history. Next, check differences through comparison with traditional printing and how printing can be understood in what aspects at the same time. After, verify how monotype and monoprint have influence on the acceptance of extended concept of 'board'. This study will show the expressional possibility of monotype and monoprint which has already known as 'tableau printing' in today's situation where adventurous experiments of printing medium are going on with the development of technology.
