This paper presents a system for medical statistical analysis that helps medical professionals analyze clinical data more easily and accurately. It is able to recommend proper methods according to the distribution of sample data, and provides guide maps composed of icons for the understanding of the process of analysis. Besides general statistical analysis, it includes commonly-used statistical methods for medical fields, such as survival analysis and methods for repetitive measurements. The results of analysis are interactively displayed by 3D glyph-based visualization with uncertainty.

NTIS(National Science & Technology Information Service) is the first national R&D information knowledge portal service in the world to provide information of government-funded R&D projects and it has been developed by KISTI. This study investigated several limitations of current NTIS information service, analyzed information needs for end users, and then proposed information recomposition and visualization method to satisfy their information needs. For doing this, we firstly clarified the definition of 'end-users' and classified three different groups of general users. We also discriminated various information needs according to three groups and illustrated some examples of visualization results to meet the requirements - 'retrieval simplification' and 'information visualization'. To consider practicality of our proposed method, we suggested implementation plans to utilize existed NTIS services.

한국과학기술정보연구원 (KISTI) 슈퍼컴퓨팅센터의 SeeMore는 국내에서 처음으로 구현된 시스템으로 지난 해 4월에 설치되었으며, 복잡하고 방대한 계산결과를 가상현실 공간상에서 시각화하여, 효과적인 해석을 가능하게 하는 과학적 가시화 시스템이라고 할 수 있다. SeeMore에서 활용될 수 있는 적용 분야는 가상현실, 과학적 데이터의 시각화, 복잡한 데이터의 분석, 기상모델링, 양자화학, 생물정보학, 물리적 현상의 모델링에 이르기까지 무궁무진하다.

The academic journal is an important medium carrying newly discovered knowledge in various disciplines. It is desirable to consider visualization of journal and article information in order to make the information more insightful and effective than text-based information. In this study, visualization service platform of journal and article information is developed. TagCloud were included in both Infographics of journal and article. Each word in the TagCloud is inter-linked with DBPedia using Linked Open Data (LOD) technique.

Visualization of the electromagnetic vector fields are presented and examined with Mathematica. Vector fields may be used to represent a great of many physical quantities in various area of physics, including electromagnetism with vector differential operators. Because they deal with abstract, three-dimensional fields that are some times very difficult to visualize, electromagnetism can be conceptually rather difficult. Visual representation of such an abstract vector fields is invaluable to student or researchers working in this field and also helps teaching electromagnetism to physics or engineering students. Mathematica provides a wider range of graphical tools including plot of vector fields and vector analysis, which can be applied to visualization of electromagnetic system. We have visualized the most fundamental concepts of the electromagnetic vector $\vec{E}=-\vec{\nabla}_{\varphi}$, $\vec{D}={\epsilon}\vec{E}$, $\vec{\nabla}{\times}\vec{A}$, $\vec{B}={\mu}\vec{H}$, $\vec{B}={\mu}_0(\vec{H}+\vec{M})$, which are confirmed with vector calculations and valid graphically with some presentations.

This study aimed to design a semi-automatic web-based pilot system 1) to build a Korean novel geo-name, 2) to update the database using automatic geo-name extraction for a scalable database, and 3) to retrieve/visualize the usage of an old geo-name on the map. In particular, the problem of extracting novel geo-names, which are currently obsolete, is difficult to solve because obtaining a corpus used for training dataset is burden. To build a corpus for training data, an admin tool, HTML crawler and parser in Python, crawled geo-names and usages from a vocabulary dictionary for Korean New Novel enough to train a named entity tagger for extracting even novel geo-names not shown up in a training corpus. By means of a training corpus and an automatic extraction tool, the geo-name database was made scalable. In addition, the system can visualize the geo-name on the map. The work of study also designed, implemented the prototype and empirically verified the validity of the pilot system. Lastly, items to be improved have also been addressed.

Digital transformation refers to the process by which a company or organization changes or innovates its existing business model or sales activities using digital technology. This requires the use of various digital technologies - cloud computing, IoT, artificial intelligence, etc. - to strengthen competitiveness in the market, improve customer experience, and discover new businesses. In addition, in order to derive knowledge and insight about the market, customers, and production environment, it is necessary to select the right data, preprocess the data to an analyzable state, and establish the right process for systematic analysis suitable for the purpose. The usefulness of such digital data is determined by the importance of pre-processing and the correct application of exploratory data analysis (EDA), which is useful for information and hypothesis exploration and visualization of knowledge and insights. In this paper, we reexamine the philosophy and basic concepts of EDA and discuss key visualization information, information expression methods based on the grammar of graphics, and the ACCENT principle, which is the final visualization review standard, for effective visualization.

Over the last few years knowledge management has become more and more impotant part of the in healthcare practices. Therefore the healthcare organisatiions have also begun to apply knowlege management strategies. To address this issue of the lack of true knowledge management in healthcare enterprises, we propose a framework for common Healthcare Knowledge Management. This framework is made up of two suites of applications and services, i.e. the intelligent agent-based knowledge management application suite and the strategic visualisation, planning and coalition formation service suite.

공정제어시스템과 같은 복잡한 시스템을 감시하고 제어하기 위한 정보 디스플레이를 설계하기 위해 두 가지의 세부적인 설계문제를 효과적으로 다루어야 한다. 정보디스플레이에서 표현할 정보의 내용을 파악하고 조직화하는 문제와 그 표현할 정보를 시각적으로 잘 표현하는 문제로 구분이 된다. Ecological Interface Design (EID)는 두 문제를 다루기 위한 이론적 배경지식과 방법을 제공하는 정보디스플레이 설계의 틀이다. EID는 1990년대 초반에 그 개념적 틀이 소개된 이후에 그 유용성이 여러 작업영역과 직무환경에서 입증되어 왔다. 그러나 실제 현장에서 EID의 개념을 활용하는데 있어 큰 어려움으로 지적된 것이 정보의 시각화를 위한 실용적이고 구체적인 원칙과 방법이 부족하다는 점이었다. 또한 EID 개념의 활용에만 집중할 경우 효과적인 정보 디스플레이 설계를 위해 고려되어야 하는 다른 설계 문제들이 쉽게 간과될 가능성도 높다. 이 점은 아직도 EID의 실제적 활용성을 높이는데 큰 약점으로 지적된다. 이 논문에서는 EID의 개요와 장단점을 소개한 후에 이에 기반해서 정보 디스플레이 설계를 종합적으로 다루는 데 도움이 될 수 있는 방법을 소개한다. 특히 이 논문에서는 기능적으로 추상화된 정보의 시각화 및 추상화 관점에서 다른 단계에 있는 정보들간의 목적-수단 관계를 시각화해서 명시화하는 것을 강조한다. 또한 디스플레이 설계 요소에 기반한 설계 프로세스 및 관련 설계 원칙 및 지침의 적절한 활용도 강조한다. 이 논문에서 제안된 방법은 EID의 개념적 틀을 확장하면서 인간 중심적인 정보 디스플레이의 설계하는데 유용한 원칙과 방향성을 정립하는데 도움이 될 것이다.

최근 들어 주식시장에 신규 개인투자자들의 유입이 많아지고 있다. 하지만 기본적인 금융에 대한 지식이 부족한 사람들이 많고 기존 서비스들은 금융 혹은 주식에 대한 이해도를 기반으로 직접 분석해야 했다. 이런 사람들을 위해 직접 분석하지 않더라도 투자할 기업을 판단할 수 있는 시각화 정보(Infographics) 서비스를 구현하였다. 필요한 정보를 얻기 위해서 open API를 사용하였는데 API의 특성상 윈도우즈 환경이 필요하여 리눅스와 윈도우즈 서버를 구축하고 서로 다른 OS 환경에서 이종 API를 처리할 수 있도록 개발하였다.
