Recently, with the increasing use of power semiconductors and microprocessors which are very sensitive to little change of power quality and for coping positively with anticipating power quality disputes between power providers and consumers which are possible to occur by of power market being formed, the power quality problem has gained preponderance among the contemporary research areas. To serve these purposes, the integrated system has been researched and developed for power quality analysis and monitoring, which provides speedy and powerful functions by the growth of computer hardware and information technology. But the advent of fast and lower price hardware make little difference in an application on many systems. As a result, the key issues of constructing power quality monitoring system are in the management of data obtained, accurate algorithms, graphic representation and user-friendly-environment for easy and clear analysis results. So, in this paper it will be introduced that the standard of user-friendly-GUI(Graphic User Interface) and analysis graphic representation for intuitive understanding of results from power quality analysis based on consideration of several systems currently being in use.

본 논문에서는 지식 표상 방식을 이용한 정보 검색 시각화 도구를 제안한다. 제안하는 정보 검색 시각화 도구는 사용자 검색이력 데이터를 이용하여 검색의도를 자동 추출하고, 추출된 검색의도를 지식 표상 방식 구조로 시각화 할 수 있도록 설계하였다. 검색의도 표상 방식을 위한 스키마는 인지 심리학적 지식 표상 방법론을 활용하였으며, 행동실험을 통해 그 효용성을 증명하였다. 실험결과 정보 검색 시각화 도구는 기존 검색방법에 비해 사용자 만족도 측면에서 약 39%의 향상이 있었으며, 정보 검색 과정에서의 재검색 문제를 해결할 수 있는 방안을 제시할 수 있었다.

스마트TV는 일반TV를 대체할 차세대 TV로 사용자경험(user experience: UX)의 중요성이 높아지고 있다. UX는 사용자의 감정 상태인 몰입, 기쁨, 흥미 정도를 평가하는 것으로 사용성과 함께 스마트TV 설계에서 고려되어야 할 중요한 원칙이며 사용만족도를 증진시켜 지속적인 구매를 유도하게 된다. 그러나 UX는 사용성보다 측정이 어렵고 생리적 또는 심리적 평가방법은 실험 비용과 실험환경의 제약이 많다는 것이 단점이 있다. 본 연구에서는 기존의 스마트TV의 UX 평가방법을 고찰한 후 새로운 UX 측정방법으로 텍스트로부터 감정을 평가하는 방법을 제안한다. 텍스트는 인터넷 쇼핑몰에서 스마트TV를 구매한 사람들이 남긴 상품후기를 사용한다. 이 방법은 설문조사 방법보다 적은 비용으로 감정을 파악할 수 있다는 것이 장점이다.

The goal of this paper is to develop a system which provides infotainment services for the healthy life of the elderly. First, we define the infotainment services for the elderly, and then determine the infotainment contents and categories related to the infotainment service. In order to provide the infotainment service, we define several modules as follow: user representation, contents generation, contents personalization, provision and learning manager. Finally we develop a pilot system which is based on the proposed framework.

This study aims to investigate the usage patterns of users in Social Network Services (SNS) where is an upsurge. Specifically, the paper considers the reason why young people more and more prefer online (or mobile) SNS activities rather than offline face-to-face social relationship. Furthermore, the drivers which affect SNS usages are considered from users' personal characteristics and social influences. User's personal characteristics include their personalities (extraversion and introversion), narcissism, and life satisfaction. Social influences involve subjective norm, visibility, and image. Affected by personal and social factors in SNS, users intend to show positive self-presentation, which refers to a behavior to selectively expose his/her goodness to others. As one of the most influential drivers affecting SNS usage, the positive self-representation has an effect on the level of SNS usage. Thus, this paper suggests the hypothesized research model focusing on positive self-representation in the relationship among personal characteristics, social influence, and user's behavior in SNS. Empirical data analysis with 100 questionnaires suggests that all hypotheses were adopted except for the effect of visibility among social influence factors on positive self-representation.

In the field of software reuse, several methods for storage and retrieval of assets abound. However, these methods often find their limits; they fail to turn up the suitable reusable assets that satisfy the needs of a particular software system under development. Two problems are the root cause of this situation. One is the lack of accurate semantics for describing software assets. The other is the ignorance of the user query context. In such a context, this paper presents an XML-based asset representation model for describing all kinds of software asset that can be reused within software development process. The proposed model provides semantic metadata for describing assets oriented user context in order to build the foundation for semantic reasoning in the retrieval process.

그래픽 유저 인터페이스 디자인에서의 아이콘들은 시각언어로서 정보를 전달하여 사용자들의 행동을 유도할 수 있는 정보전달 매체이다. 그래픽 사용자 인터페이스에서 사용자와의 커뮤니케이션 수단으로 아이콘을 사용하는 것은 사용자가 인지하기 쉽기 때문에 임의의 사용자에게 원하는 시각정보를 효과적으로 제공하고 커뮤니케이션 효율성을 증대시키기 위해서는 Graphic User Interface이라는 매체의 특성에 적합한 아이콘 개발이 이루어져야 한다. 본 연구에서는 아이콘 유형인 그림 아이콘을 중심으로 하여 그림 아이콘의 각 세부적 표현 유형의 선호도에 따른 조형적 영향 요소간의 상관관계를 파악하며 각 표현 유형에 영향을 주는 조형 요소들이 무엇인지를 알아보았다. 이를 바탕으로 아이콘 디자인에서 사용자 선호 지향적 디자인 방향에 대한 지침을 제공하며 디자인을 할 때 데이터로 활용할 수 있는 이론적 근거를 제시하도록 하였다.

In Regarding urban geo-spatial information visualization in this study, visualization of physical attribute information is mostly related to the representation of spatial domain and physical objects, and visualization of non-physical attribute information has to do with visualizing citizens and their activity information in the physical environment. In particular, a citizen, one of the non-physical information attributes, is characterized by a constant mobility in the physical environment, and thus visualization of his/her activity information is vital in conveying information because this information may not be depicted with any given, fixed figures. In consideration of this difficulty, this study integrates interrelationship among urban space, human needs, social relations, and lifestyles into a 'high-tech' service where experience in time and space is possible. To analyze the web-service and visualization cases, the study has selected visualization indicators consisting of information representation objective, information representation means, and information representation result. The results of the case analysis through specific indicators set a range in information representation objective, means, and result, thereby forming a user-friendly environment in which representational results are readily available to users, and ultimately expanding the users' selection range coming with a variety of options. This study also assumes that a wide range of service provision is needed to reflect users' needs in developing urban geo-spatial service model, and the display of its results should visualize users' satisfaction to construct the best information needed to users.

EDISON is a web-based platform that provides easy and convenient use of simulation software on high-performance computers. One of the most important roles of a computational science platform, such as EDISON, is to post-process and represent the simulation results data so that the user can easily understand the data. We interviewed EDISON users and collected requirements for post-processing and represent of simulation results, which included i) flexible data representation, ii) supporting various data representation components, and iii) flexible and easy development of view template. In previous studies, it was difficult to develop or contribute data representation components, and the view templates were not able to be shared or recycled. This causes a problem that makes it difficult to create ecosystems for the representation tool development of numerous simulation software. EDISON-VIEW is a framework for post-processing and representing simulation results produced from the EDISON platform. This paper proposes various methods used in the design and development of the EDISON-VIEW framework to solve the above requirements and problems. We have verified its usefulness by applying it to simulation software in various fields such as material, computational fluid dynamics, computational structural dynamics, and computational chemistry.
