New media which appeared in accordance with the development of IT technology includes elements of the interaction to be developed as an interactive media. In the field of interactive media which can be most actively applied, there is the filed of experience exhibition based on the active participation of people who experienced. Interactive media applied to the experience exhibition area, in order to have an effective communication that is based on a high degree of immersion, has been utilized as a platform for educational contents. This study is intended to explore the elements of visual perception for developing an optimized interface in the perspective of children who are the main subject of educational contents to present the criteria for the development of an interface for children. Thus, this paper derives the elements by the analysis of the visual perception elements of children and the experiment for the immersion environment. By analyzing the results, this study is to present the criteria of the visual perception elements for the development of interactive media contents for children.

We developed an optimal design interface based on VBA(Visual Basic Application) that takes advantage of API(Application Program Interface) function of commonly used EM analysis software. The developed interface is adopted for an optimal design of a septum in a waveguide tee junction using PSO(Particle Swarm Optimization) algorithm. The objective function of the optimal design is defined by $S_{11}$-parameter of the waveguide tee junction Design variables are established as position of the septum, that are changed to satisfy the design goal Using the developed design interface and PSO algorithm, the objective function converged to the smallest value, showing the validity of the proposed method. The design interface was developed using Microsoft Excel software, enabling easy control of design parameters for user. Also, various analysis parameters can be set in the Excel interface, including waveguide input mode and frequency. After completion of the design, field solutions at user-specified positrons can be extracted to the output files in complex number form.

This paper presents critical steps in building client/server application with UML and Visual Basic, which are derived from the implementation case of a typical order processing system. To begin with, we briefly review the software architecture, the diagrams and the object-oriened building process in the UML. In the inception phase, it is critical to define the project charter, to draw use case diagrams, and to construct a preliminary architecture of the application. In the elaboration phase, it is critical to identify classes to be displayed in the class diagram, to develop user interface prototypes for each use case, to construct sequence diagram for each use case, and finally to design an implementation architecture. Steps to construct implementation architecture are given. In the construction phase, it is critical to design both the database and components. Steps to design these components are described in detail. Additionally the way to create the Internet interface is suggested.

Several studies indicated that an independent visual background (IVB) reduced simulator sickness (SS) and balance disturbance associated with exposure to virtual environments (VEs) and motion simulators. A recent study showed that an IVB comprised of an earth-fixed grid was less effective in a complex driving simulator than in a simple VE. Subjects' post-experiment reports indicated that the VE motion "induced" motion of the earth-fixed grid m. This led to the suggestion that an IVB comprised of clouds would be less subject to induced motion and therefore would alleviate nausea more effectively than a grid IVB. Clouds are "natural" and are usually perceived as relatively stable, whereas a grid has no inherent stability. 12 subjects were exposed to complex motion through a simulated environment in a driving simulator under 3 IVB conditions: grid, less clouds, many clouds. They reported less nausea when the many-cloud IVB was used relative to the grid IVB condition. grid IVB condition.

According to glowing computing capacity, software in remote sensing has supported diverse processing interfaces from batch interface to high-end user interactive interface. In this paper, component based visual modeler is developed to process batch jobs for high-end users as well as novices. Visual modeler arranges several node groups which are categorized according to their purposes. These nodes carry out elemental unit processes and can be grouped to model. The model represents user specified job which is composed diverse nodes. User can organize models by connecting diverse nodes according to data flow model specification which rules node's connectivity and direction, etc. Furthermore, user defined models can be together to organize much more complex and large model.

본 연구는 빠르게 발전하는 음성 기반의 디바이스가 스크린 중심의 미디어 멀티태스킹 환경에 어떤 변화를 가져올 수 있을지 확인하고자 했다. 서로 다른 자원 구조를 가진 과업을 동시에 수행할 때 정보 처리 효율이 높아진다는 이론적 근거를 토대로, 시각 주의가 필요한 과제와 음성 또는 스크린 기반의 디바이스를 활용해 정보를 검색하는 과업을 동시에 수행하는 실험이 진행되었다. 실험 결과, 과업수행 환경과 인터페이스 감각양식은 모두 인지부하에 유의미한 영향을 미쳤다. 음성 인터페이스 그룹에서 전반적으로 인지부하 수준이 높게 나타났는데, 단독으로 사용된 단일 과업 조건보다 시각 과제를 동시에 수행한 다중 과업 조건에서 시각 인터페이스 그룹과의 차이가 줄어들었다. 과업 수행도의 경우 음성 인터페이스 그룹에서 시각 과제에 대한 수행능력이 시각 인터페이스 그룹보다 더 높게 측정되었다. 이러한 결과는 멀티태스킹 환경에서 음성 인터페이스를 사용했을 때 동시적 과업을 청각 경로와 시각 경로로 나누어 처리함으로써 인지부하와 과업수행에 이점이 나타났음을 의미한다. 이는 시각 자원의 충돌이 발생하기 쉬운 스크린 중심의 미디어 멀티태스킹 환경에서 음성 기반의 디바이스가 효율적 정보 처리를 촉진시키는 잠재적 역할을 할 수 있다는 함의점을 제공한다. 본 연구는 다중 자원 이론을 통해 자원의 분산처리에 대한 이론적 증거를 제시하고, 스레드 인지 모델을 기반으로 음성 인터페이스를 활용했을 때의 이점을 더욱 구체적으로 규명하고자 했다.
