최근 영상 매체는 3D와 인터랙션분야를 중심으로 크게 발전하고 있다, 이는 3D 영상 구현을 위해 필요한 기술의 발전이 이루어지고 사용자에게 보다 높은 몰입감과 현실감을 주는 3D 그래픽의 장점 때문이다. 3D 영상 콘텐츠의 발전과 다양한 영상매체의 개발은 필연적으로 지금의 인터페이스구조의 변화와 혁신을 가지고 올 것이며 이는 2D 인터페이스가 가지고 있는 한계를 3D 인터페이스의 효율성으로 극복할 수 있을 것이다. 그 장점은 3D 인터페이스가 자율성(Autonomy), 상호작용성(Interaction), 현재성(Presence)의 특징을 구현할 수 있기 때문이다. 따라서 위와 같은 3D 인터페이스의 발전 가능성을 검증하기 위해 동일한 내용의 정보를 2D와 3D의 두 가지 인터페이스로 구현하여 비교해 본다.

Structural equation modeling is pointing to statistical procedures that simultaneously perform path analysis and confirmatory factor analysis. Today, this statistical procedure is an essential tool for researchers in the social sciences. There are as (AMOS, LISREL and PLS) representative tools that can perform structural equation modeling analysis. AMOS provides a convenient graphical user interface for beginners to use. PLS has the advantage of not having a constraint on normal distribution as well as a graphical user interface. Therefore, we compared and analyzed the three most commonly used tools in social sciences. This study suggests practical and theoretical implications based on the results.

The paper describes implementation of three-dimensional visualization system that is to provide comprehensive meaning of the statistical prediction results on the marine casualties. Graphical User Interface (GUI) and Web based Virtual Reality (VR) technology are mainly introduced in the system development. To provide daily forecasting, time based casualty prediction model and risk level index are developed in this work. As operating test results of the system, complicated statistical meaning can be shown in the three-dimensional virtual space using simple color. In addition, daily risk levels can be shown on the bar-graph.

The paper describes on the implementation of three-dimensional visualization system that is to visualize meaning of the statistical prediction results of marine casualty with easy of understanding. Graphical User Interface(GUI) and Web based Virtual Reality (VR) technology are mainly introduced in the system development. In addition, the time based prediction models of the marine casualty and the risk level are developed to display daily situation. As operating test results of the system, it is known that complicated statistical results can be shown as simple colour in the three-dimensional virtual space.

This paper introduces the basic concepts and requirements of database system based on the object-oriented paradigm,and presents the overview of the design of an object-oriented data base system which refects those conceprs and requirements . The system imolemented on C++,consists of three structure layers.The inner layer, which is in fact a storage system,performs file I/O,while the inermediate layer is responisible for most of the functions except the ones rerated to the user interface, such as the transaction management,the schema manage-ment,and the management of buffers in main memory etc.The outer layer,designed mainly for the uwerunteface,mot only privides the functions for graphical user interface,preprocessor,and interpreter etc,but also supports extended SQL for object-oriented features.

과거에는 지리정보시스템이 고가의 엔진을 사용하여 구축된 지리정보데이터를 활용하였다. 따라서 단지 전문가나 특정한 사용자 중심으로 활용되었으나 인터넷 기술의 급속한 발전으로 언제 어디서나 지도를 이용하려는 일반 사용자들의 요구가 급격히 증가하고 있다. 이에 본 논문에서는 여러 지리정보검색의 구현기술 중 Java의 Servlet기술을 이용하여 관광지리정보검색 시스템을 구현하여 서버의 과중한 부하를 막았으며 진보된 그래픽과 인터페이스를 제공하고 데이터 보안성의 문제와 동적으로 변하는 자료의 시각적 표현을 구현하였다.

Many People are collecting and managing variable information(Image, Graphic, Animation, Text, music files etc.) about personal interests and holding them in common. Most users are using Microsoft Explorer to make a folder and classify many files. but It's difficult to understand the relation of the data instinctively. To resolve this problem, we adopt information visualization method (especially tree-graph control interface). We suggest an interface that all user can drawing a Graph easily and rapidly. So user can see the relations of their data instinctively and control the relation directly with our sketch-based interface.

Although data analysis in earlier days had been sufficiently done only by character user interface, users of these days are more used to the graphic user interface and the requirements for the user interface are gradually varying and increasing. In order to meet users' various wants and needs and to develop well-equipped interface, not only software developers but also professional designers who can complement the technique of the developers are needed. But in reality there are many restrictions and difficulties for developers and designers to work together cooperatively. Moreover, developing user interface in use of 3D type of graphics and animation techniques causes the rise of the developing cost. The thesis attempts to design and implement 3D visualization for real-time sensor data collected by the various environmental sensor and measuring devices, by using WPF (Window Presentation Foundation) which can make both developers and designers work together cooperatively and which makes it possible to implement various multimedia functions such as a 2D and 3D type of graphics, animation techniques, and an acoustic effect.

The final goal of this research is development of graphic design evaluation methodology in elevation of a usability at the mobile internet services and of measurement model which can forecast user needs in interface design, and systemize evaluation basis. For this, we systemize core contents of GUI design evaluation methodology and embodied UI design support system that supports prototype layout and evaluation process directly. The sight language that can inform flow of controled information by the quick and implicated method so that user may complete task in a short time without overload of recognition in limited display environment of Small Screen device it must improve objectivity in the reflection of UI design with image. Thus evaluation methodology that can evaluate usability of mobile internet systematically is important and specially, graphic design evaluation model which can forecast user's design need and trend is meaningful because of special quality that can reflect sensitive aspect of user in interface design. Mobile internet GUI was done by the result of this design evaluation, and I hope this result can be utilized for the GUI development of Ubiquitous environment for the future research.
