This study was conducted to analyze the Korean inclination to visual equivocality. Similar studies conducted by several psychologists were reviewed in order to determine whether we can put equal value on the visual equivocality which is often shown in natural appearance. This Korean inclination was also investigated with the help of a public survey. The following conclusions were derived from the study. - In reality, there is no visual equivocality for Koreans except in some specific cases. - It is true that, on a screen, a diagonal line from the lower right to the upper left produces a stronger feeling of upward tendency than one from the lower left to the upper right. - The idea that the right side of a screen looks heavier than the left one was not supported and should be rejected for Koreans. - It was discovered that the user interface is working when a person is describing a natural appearance or looking at a description. This fact is generally accepted for Koreans, the majority of whom are right-handed. - Until now, the idea of a Korean superiority toward the left side in visual expression has been found in our culture. In short, it was uncovered that Korean people generally do not have visual equivocality but, instead, have an inclination to left side rather than the right from various aspects.

State-space method for the analysis of the dynamic characteristics of a body motion is set up as mathematical tool for the solution of differential equation by computer. Representation of a system is described as a simple form of matrix calculation and unique form of model is available for the linear or nonlinear, time variant or time invariant, mono variable or multi variable system etc. For the analysis of state-space method a complicated vector calculation is required, but this analysis can be simplified with the specific functions of a software package. Recently as the Graphical User Interface softwares are well-developed, then it is very simplified to execute the simulation of the dynamic characteristics for the state-space model with the interactive graphics treatment. The purpose of this study is to developed the simulator for the educational analysis of the dynamic characteristics of body motion, and for the analysis of the longitudinal dynamic characteristics of an aircraft that is primarily to design the simulator for the analysis of the transient response of an aircraft longitudinal stability.

A hybrid information environment can be described as one where an appropriate range of heterogeneous information services is presented to the user in a consistent and integrated way via a single interface. The purpose of this study is to suggest a need of hybrid information services through understanding of the hybrid information environment and hybrid library. Additionally, this study deal with basic concepts of design for a hybrid information service model and address a number of hybrid library projects based on these concepts, such as Agora, BUILDER, HealdLine, HyLife, and MALIBU. Finally, this study survey generic a model of hybrid library and suggest basic principles for building of hybrid information service model, such as integration, seamlessness, authentication, interconnectivity, and personalization of information seeking process environment.

Recently, many interests on the ubiquitous environment and the practical technologies associated with it have been significantly increasing along with the rapid development of wireless technologies. The development of the automated systems based on the ubiquitous environment is required as the concept of the term "ubiquitous" is integrated into the fields of existing IT. In this paper, we design and implement a power-saving management system using RFID/USN technologies. It efficiently manages the power consumption of the electronic machine such as electric lights, electric heaters, and air conditioners in a building. The proposed system controls the electronic machines and monitors their status by RFID and collects the real time information about the surroundings and power consumption of the electronic machines by USN. Especially, it analyzes the real time information and supports the intelligent scheduler with the best power-saving. Finally, this paper shows the difference between the proposed system and the existing systems and the reality of our system through the real time user interface about the power-saving management.

Recent exhibition's paradigm is changing from the existing unidirectional oriented exhibition form to a form of interactive hands-on exhibits that viewers can get and realistically feel a variety of information. Hands-on exhibit embodies the human interface by utilizing light, sound, pressure, etc. in time and space. In this paper, we have studied the creation of fractal image by the Mandelbrot technique and proposed the interaction method for it to be converted into a variety of forms. By using the proposed method, a variety of image transformation such as printmaking effect, sketch effect, Pop Art effect can be performed, according to clicking a certain fraction on the created fractal image screen by a user mouse. Interactive image generated in this study are expected to be used for trade shows, promotional products, media art design.

Representative sleep disorders represent sleep apnea and snoring. Although researches to diagnose sleep disorders as solutions for these problems are going on, the original researches only diagnose and measure sleep disorders but ones to find out the reasons are not activated much. Therefore, to reinforce this, this paper suggests sleep disorder improvement system based on multi-sensor. To design the system proposed in this paper, the entire system's structure was found and data's flow was planned. To ensure that the system works, mobile application and user interface was built based on Android. To test the results on accuracy of sleep disorders improvement system based on ontology using multi sensor built and planned in this paper, a scenario was written. As a result of testing inference results' accuracy changing factor values of sleep disorders following test scenario, proposed sleep disorders improvement system's accuracy was checked.

We have developed software for converting the volumetric voxel data obtained from X-ray computed tomography(CT) into computer-aided design(CAD) data. The developed software can used for non-destructive testing and evaluation, reverse engineering, and rapid prototyping, etc. The main algorithms employed in the software are image reconstruction, volume rendering, segmentation, and mesh data generation. The feasibility of the developed software is demonstrated with the CT data of human maxilla and mandible bones.

In this paper, we design and implement a multiple-view VoiceXML editor to improve editing efficiency of the VoiceXML. The VoiceXML multiple-view Editor uses a MVC framework to support multiple views and paradigm. Our multiple-view editor consists of Model. View and Controller using MVC framework. A model, core data structure. is constructed of abstract syntax tree and abstract grammar. A view. user interface. is formalized in unparsing rules and unparser. A controller. to control model and view. is made of command interpreter and tree handler. The VoiceXML multiple-view editor overcomes a drawbacks of existing XML editors by showing document structure and context concurrently. as well as document flows. Our VoiceXML multiple-view editor. which MVC framework has been applied, provides various editing views concurrently to users. Thereby. it supports efficient and convenient editing environments for voice-web documents to users and it guarantees transparency of editors. as various views have a same consistent model.

In this paper, we propose a virtual surgical planning system specialized to mandible reconstruction surgery. Mandible reconstruction surgery is one of the most difficult surgeries, even for experienced surgeons. Compared to the traditional surgical procedures, virtual surgical planning can reduce the operation time in operating room while expecting better surgical outcome with optimized planning. However, with existing software systems, it requires much time and manual operations in virtual surgical planning. To reduce preparation time and improve accuracy of virtual surgical planning, we have developed optimized functions for virtual surgical simulation of mandible reconstruction with user-friendly interface. We found that the proposed system shortened the preparation time by half compared to the existing system from the experiments. The proposed system supports surgeons to make accurate plan faster and easier. The virtually planned results are used to make surgical cutting guide by 3D printing, and this will enhance surgical performance in operating room.
