This study proposes a requirements monitoring method that systematically performs traceability management and change management for requirements in order to improve the quality of software systems in the software development process. To this end, we present the artifact change history management models to systematically perform change management for individual artifacts and the traceability matrixes to define the relationship between artifacts. It also proposes a visual dashboard that makes it easy to grasp the situation in which changes are propagated to related artifacts when specific artifacts change.

Research into the visual perception of human emotion to recognize an intention has traditionally focused on emotions of facial expression. Recently researchers have turned to the more challenging field of emotional expressions through body posture or activity. Proposed work approaches recognition of basic emotional categories from body postures using neural model applied visual perception of neurophysiology. In keeping with information processing models of the visual cortex, this work constructs a biologically plausible hierarchy of neural detectors, which can discriminate 6 basic emotional states from static views of associated body postures of activity. The proposed model, which is tolerant to parameter variations, presents its possibility by evaluating against human test subjects on a set of body postures of activities.

While the method of information collection and visual interface technique have been researched actively on web information retrieval, a study on structured modeling for effective classification of a wide collective information leaves to be desired. In this paper, we represent information feature based on structured information model. It aims at carrying out effectively the user's retrieval environment through visualization technique with analyzing the information feature. We propose a information classification method using Facet units and we construct the object model, table model, SQL code to define the relation of the information, and represent the information feature based on a wide range of views. After users gain a better global understanding of the information feature, retrieve more easily through their information. Conventional information retrieval is user-oriented to be what user want, but proposed technique it data-oriented which helps users to understand what exist in database by showing information feature.

정보시스템의 개발에 있어서 요구사항의 체계적인 관리가 중요시되는 가운데, 요구사항에 대한 세부적인 정보들을 계량적으로 관리하기 위한 체계적인 분류방법이 부족한 것으로 판단되어, 요구사항을 업무로직, 데이터, 기술기반 관점 및 CEO/CIO, 책임자, 설계자 시각에 따른 요구사항 분류매트릭스를 제공함으로써, 요구사항을 좀더 체계적으로 수집, 관리할 수 있는 기반을 마련하였다.

The appearance of Internet, the 5th medium which has succeeded newspaper, magazine, TV, radio, creates WEB MAGAZINE to overcome the restriction of space and time. This paper has conducted the contents and visual points of view in webmagazine. Through case study, the following and identify for the analysis of the webmagazine contents and visual format. Firstly, communiation at webmagazine is carried out at the user-centered atmosphere. Secondly, Even through an aesthetic is emphasized in the webmagazine, when web designer compose of the web site, it is necessary to find the proper methodology under the basis of users behavior Thirdly, Although webmagazine required the visual form, we should know that the evaluation of webmagazine should be implemented by users. Therefore, webmagazine should be designed by the user-centered layout.

In this study, we try to examine its features by using the methods of systematic infographics analysis for visualization materials that are used in Physics I textbooks. Thus, after developing the analytical framework infographics, visualization materials is described in the section "information and communication" and have been analyzed separately as "data visualization" and "Infographics." The results of this study are as follows. First, the analysis framework of infographics can be classified contents of the information, visual representation, and media method. Second, the visualization materials that are displayed in the section "information and communication" of Physics I textbook are of higher quality than most schematized data that are graphically, simple information. Third, the features of visualization materials in textbooks have many relations & functions on 'information content', text & metaphor on 'visual element', illustration & comparison on 'expression type', graphic on 'expression mode', printed matter on 'media method', and horizontal & vertical type on 'the flow of attention'. From the analysis results, in the section "information and communication" of Physics I textbook uses a lot of visualization materials, however it does not provide rich infographics but only simple graphical materials. By utilizing the results of the analysis of textbook and analysis framework of infographics, which has been developed through the this study, let us hope that the opportunity to be able to grasp the importance of infographics in science education be provided.

오늘날 정보시스템 실패의 많은 원인이 기술적인 문제만을 중시하고 정보시스템과 관련된 조직, 또는 관리적인 요소들을 소홀히 하기 때문이라는 지적이 있다. 여러 MIS 학자들은 정보시스템 개발 시 이러한 기술적인 관점에로의 편중의 원인을 시스템 개발자들이 가진 편협된 준거체계(Frame of reference)에서 찾고 있다. 그러나 이러한 주장들은 아직까지 단순히 이론적인 단계에 그치고 있는데, 본 연구는 이러한 주장에 대한 실증적 근거를 제시하고자 한다. 그 방안으로 본 연구는 시스템 분석가의 준거체계와 시스템 개발 시 분석가가 발견하는 개발시의 문제의 유형간의 관계를 제시하고 있다. 본 연구의 결과 사회-기술적(Socio-technical)이거나 사회적인(Socio) 준거체계를 가진 분석가들이 기술적인(Technical) 준거체계를 가진 분석가들보다 더 조직적인 문제를 많이 발견하고 중시함이 나타났다. 그리고 통계적으로 유의하지는 않았지만, 사회-기술적인 시스템 분석가들이 사회적이거나 기술적인 준거체계를 가진 분석가들 보다 기술과 조직적인 문제 모두에 균형있는 관점을 유지하고 있음을 알 수 있었다. 이러한 본 연구의 연구결과는 학문적이며 실무적인 시사점을 제시하고 있다. 우선 학문적 시사점을 살펴보면, 시스템 개발 현장에서 조직과 관리적인 관점의 문제가 소홀히 다루어지는 원인을 알아 볼수 있는 이론적 배경을 제공하고 있다는 것이다. 그리고 실무적 시사점은 보다 균형 있는 시각을 가진 시스템 분석가를 만들기 위하여 학교 프로그램에서 어떤 교과과정을 만들어야 하며, 또 기업의 정보시스템 관리자들이 평소에 어떤 문제들을 보다 많이 강조하고 상기시켜야 할 필요가 있는지를 알려 준다는 것이다.

Graphical user interfaces (GUI) in modern software deliver information visually, and a well-designed interface can provide information to the use in an organized and intuitive manner while poorly-designed interfaces can cause visual inconvenience and confusion. In order to effectively deliver information to the user, visual attention should be placed on a prominent location in the image. This paper introduces a method based on a human visual system (HVS) that can improve Metro-style GUIs by reducing a user's workload to visually find information. Our method is designed with spatial mapping and color mapping for buttons in the Metro-style GUI. Also we define a metric for Metro-style GUI effectiveness, including an optimization algorithm. The results show that our method improves the performance of visual search tasks in a Metro-style GUI.

The purpose of the present research was to examine whether the visual system importantly use binocular disparity information in color-motion binding. Wu, Kanai and Shimojo (2004) reported an illusory color-motion binding which was observed in the peripheral visual area when observers fixated on the central area of visual stimulus. We have found that illusory rotor-motion binding was not observed at the situation where binocular disparity was available but was where it was not available. These results imply that the visual system uses binocular disparity information when it binds rotor and motion and that the binding process occurs after binocular disparity information is processed.

Recently, the structural similarity (SSIM) index metric is proposed. In the present paper, a new framework, which is called visual SSIM (VSSIM), is proposed by incorporating crucial human factors into the SSIM. The human factors are foveation, luminance, frequency and motion information. The performance of VSSIM is evaluated by subjective quality test compliant with the Video Quality Expert Group (VQEG) multimedia group test plan. It shows that the visual SSIM is more correlated with the subjective quality result than the conventional SSIM.
