OpenVG는 낮은 수준의 하드웨어 가속 기능과 이를 바탕으로 하는 2D 벡터 그래픽 렌더링 API를 제공함으로써 모바일 환경에서 높은 화질의 그래픽을 구현할 수 있다. 이러한 장점에도 불구하고 OpenVG 엔진을 이용한 실제 사용자 인터페이스(User Interface)의 구현은 쉬운 일이 아니다. 그 이유는 OpenVG API에서는 기존의 개발 환경에서 제공하는 기본적인 위젯 컴포넌트(Widget Component)를 제공하지 않기 때문이다. 본 논문에서는 OpenVG를 용이하게 사용하여 효율적인 UI 구현을 위한 위젯 컴포넌트 시스템을 제시하고자 한다. 우선 OpenVG 엔진을 기반으로 위젯 컴포넌트와 그들 사이의 계층 구조와 상관 관계를 설계하고, 시스템이 구동되는 방식을 기술한다.

The customer satisfaction of WAP service greatly relies on the usability of the service due to the limited display size of a mobile phone and limitation in realizing UI (User Interface) for function keys, browser, and OS (operating system) Currently, a number of contents providers develop and deliver varying services, and thus, it is critical to control quality level of UI in consistent standards and manner. This study suggests usability index evaluation system to achieve consistent UI quality control of various WAP services. The system adopts both top-down and bottom-up approaches. The former concerns deriving UI design components and evaluation checklists for the WAP, based on the usability attributes and UI principles. The latter concerns deriving usability-related evaluation checklists from the established UI design features, and then grouping them from the viewpoint of usability principles and attributes. This bidirectional approach has two outstanding advantages: it allows thorough examination of potential elements that can cause usability problems from the standpoint of usability attributes, and also derives specific evaluation elements from the perspective of UI design components that are relevant to the real service environment. The evaluation system constitutes a hierarchical structure by networking usability attributes, UI guideline which indicates usability principles for each attribute, and usability evaluation checklist for each UI component that enables specific evaluation. Especially, each evaluation checklist contains concrete contents and format so that it can be readily marked in O/X. The score is based on the ratio of number of items that received positive answer to the number of total items. This enables a quantitative evaluation of the usability of mobile WAP service. The validity of the proposed evaluation system has been proved through comparative analysis with the real usability problems based on the user test. A software was developed that provides guideline for evaluation objects, criteria and examples for each checklist, and automatically calculates a score. The software was applied to evaluating and improving the real mobile WAP service.

The way of mobile apps development using open source software have been becoming increasingly popular recently. In opensource mobile User Interface components case, there is tends to much more be used than mobile functional components. Because it is more easier that the reusability for implementation of User Interface. The problem is to apply as an open source mobile components selected for this reason all of the existing two studies. It is an open source software selection process and selection procedures shelf components. We revise to conform to existing mobile components selected for the study on open source software selection process in this paper. Can help increase the productivity of the mobile app development by the open source components to meet the functional requirements when developing mobile apps that can be easily retrieved and presented the selection process of this study is effective.

고령 사회의 급격한 확대로 인해 스마트 기기를 잘 다루는 스마트 시니어들의 문화향유가 급증하고 있다. 시니어 세대는 인지 및 운동능력이 급격히 감퇴하는 시기로, 콘텐츠를 활용한 원활한 문화향유를 위해서는 감퇴하는 능력에 대한 개인의 능력을 파악하여 콘텐츠 제작자들에게 알맞은 가이드라인을 제공해줄 필요가 있다. 본 연구는 시니어의 인지 및 운동능력 측정을 통하여 웹콘텐츠에 사용되는 UI/UX 컴포넌트를 매핑하고, 컴퓨터 과학에 전문적인 지식이 없는 개발자 또는 콘텐츠 제작자들에게 시니어를 잘 이해할 수 있도록 하는 시각화 방법을 제안한다.

In general, the characteristics of components which consist of multi-component system can not be the same. This paper proposes a maintenance model of multi-component system considering the characteristics of each component. In this paper, multi-component system is divided into three components-critical unit, major unit and minor unit, respectively. This paper determines the optimal replacement time of the system which minimizes total maintenance cost, optimal replacement period of major unit and initial stock quantity of minor unit within this optimal replacement time. Numerical examples are shown when the failure times of each unit have gamma distribution.

In order to complete the AR UI design simply and quickly, the usable factors were studied in this thesis. The primary aim of interface design is to increase the usability. The various factors should be considered together when we evaluate the usability. The idealized usable working model is based on user-centered with the aim of perceiving the interests of users, operating easily and completing targets. In order to ensure the types of usable factors, literature survey method had been used and a total of 85 usable factors had been collected by this survey. To make the usable factors can adapt the augmented reality, the concept of factors should be redefined. We extract the items which is adaptable and user-centered, combine or delete the items that have the same meanings and finally select 25 usable evaluative factors. Then we take HCI professional as the object and collect the data by Heuristic Evaluation. We systematize the usable factors by Principal Component Analysis, and observe the correlation between the usable factors and classify those which have high correlation.

At present, Authoring tools, which are used to develop the WIPI applications are less convenient to be coded. Usually, the programming tools only focus on the grammar while scarcity of visualization. Developer forced directly codes all times during the development by this cause. As a procedure for rapid WIPI Application Development, in this paper, WIPI API High Level Component is first visualized, in order words, graphic control is developed. Second this control is used in designing the mobile layout. Then UI Markup Language and source code can be generated automatically. With this view, we propose the JIML(Jlet Interface Markup Language) with UI Markup Language based XML of WIPI Jlet Platform and also present the transformable rule for generation to the WIPI code about WIPI Jlet UI from offered JIML. Also we implement the WIPI Jlet Generation System to make the generation to JIML, WIPI code. The Implemented System provides efficiency when developing WIPI Business Application, and helps to enable rapid development.

The user interface is the medium, which provides the users to have an access to the web-based information system. The user interface is the means of improving usability and accessibility for the user, as well as being the core component in the web-based information system. In this paper, the audit framework of the user interface was developed to upgrade the usability and accessibility; it was based on the three basic components of the current audit framework in the web-based information system. At the time of an audit, the UI process of the 'Analysis', 'UI Design', 'UI Production', and 'Test' was defined, which was analyzed through the web development methodology. Also, for the area of an audit, the 'Information', 'Design', and 'Technology' were defined by the analysis of the components that makes up the user interface, From the view of an audit, the standard criteria of an assessment were set as 'Usability', 'Accessibility', and 'Cross Browsing'. Through the framework that was proposed in this paper, practical audit applies the performed examples. By this, the efficiency of the proposed framework was verified.

Fine microgroove is the key component to fabricate micro-grating, micro-grating lens and so on. Conventional groove fabrication methods such as etching and lithography have some problems in efficiency and surface integrity. This study deals with the creation of ultra-precision micro grooves using non-rotational diamond tool and CNC machining center. The shaping type machining method proposed in the study allows to produce V-shaped grooves of $40\mu{m}$ in depth with enough dimensional accuracy and surface. For the analysis of machining characteristics in micro V-grooving, three components of cutting forces and AE signal are measured and processed. Experimental results showed that large amplitude of cutting forces and AE appeared at the beginning of every cutting path, and cutting forces had a linear relation with the cross-sectional area of uncut chip thickness. From the results of this study, proposed micro V-grooving technique could be successfully applied to forming the precise optical parts like prism patterns on light guide panel of TFT-LCD.
