To establish systematic diagnosis and treatment planning of dentofacial deformity patient including facial asymmetry or hemifacial microsomia patient, comprehensive analysis of three dimensional structure of the craniofacial skeleton is needed. Even though three dimensional CT has been developed, landmark identification of the CT is still questionable. In recent, a method for correcting cephalic malpositioning that enables accurate superimposition of the landmarks in different stages without using any additional equipment was developed. It became possible to compare the three-dimensional positional change of the maxillomandible without invasive procedure. Based on the principle of the method, a new program was developed for the purpose of diagnosis and treatment planning of dentofacial deformity patient via three dimensional visualization and structural analysis. This program enables us to perform following menu. First, visualization of three dimensional structure of the craniofacial skeleton with wire frame model which was made from the landmarks observed on both lateral and frontal cephalogram. Second, establishment of midsagittal plane of the face three dimensionally, with the concept of "the plane of the best-fit". Third, examination of the degree of deviation and direction of deformity of structure to the reference plane for the purpose of establishing surgical planning. Fourth, simulation of expected postoperative result by various image operation such as mirroring, overlapping.

The purpose of this paper is to reinterpret and visualize the medieval Arab's studies on the geometric methods of solving the cubic equation by utilizing Apollonius' symptom of the parabola. In particular, we investigate the results of $Kam{\bar{a}}l$ $al-D{\bar{i}}n$ ibn $Y{\bar{u}}nus$, Alhazen, Umar al-$Khayy{\bar{a}}m$ and $Al-T{\bar{u}}s{\bar{i}}$ by 4 steps(analysis, construction, proof and examination) which are called the complete solution in the constructions. This paper is available in the current middle school curriculum through dynamic geometry program(Geogebra).

In this study we developed the visualization scheme of spatial ground-motion measurements in real time by using DSS data. Even though this scheme itself is useful for national earthquake mitigation plans, this scheme could be served as the crucial core for constructing rapid earthquake damage evaluation system. DSS is the abbreviation of Data Subscription Service and this is the pre-assigned request for the seismic stations to send very limited brief data with high priority and negligible transmission load. In addition to visualize the damage area with intensity, the corresponding epicenter can be estimated roughly for quick event alarm. For the interpolation of spatially irregular PGA data, the program, named as surface. of GMT was used with NetCDF grid file format. Since the grid file is similar to a postscript file, the program, called as shading, was coded with C language by using Matpak library in order to convert grid files into image files.

To prevent problems caused by welding deformation, preparation in the design stage is necessary. Countermeasures in the design stage is also the most cost-effective method. In this study, to give designers information on the welding deformation, a system to visualize the welding deformation is developed. The model to visualize the deformation is the stiffened plate common in steel structures. To increase computational efficiency, theoretical solutions to calculate the deformation of plate and stiffener are used instead of numerical analysis. Also, to secure accuracy, experiments to estimate bending moment causing welding deformations are performed. A computer program written with Visual C++ is developed for interactive data input, calculation of welding deformation and display of deformed shape. Designers can change the design in the early stage after checking the deformed shape by this system.

The purpose of this study was to develop science and art integrated program to improve the creativity of scientifically gifted elementary school students. This study was to develop science and art integrated program to enhance the creativity of these subjects. This program was consisted of 30 lessons covering 10 topics. It was developed of five stages including the observation stage reflecting the characteristics of the right hemisphere relevant to creativity, the interest and curiosity stage, the experiment design and performing stage, the internalization stage, and the stage of expressing arts. This program was applied to 20 senior gifted students in Y Elementary School in Gyeonggi province. Torrance Tests of Creative Thinking(TTCT) was used in order to investigate and measure the effectiveness of the program before and after its use in class. The results of this study are as follows: First, this program showed results of significant improvement of creativity of scientifically gifted elementary school students after its use in class(p<.05). Second, it was significantly effective in increasing their creativity, especially in the subdomains such as originality, abstractness of title, and territory of resistance on hasty conclusions after its use in class(p<.05). Third, it was significantly effective to increase the Creativity Index that represents creative potential(p<.01). In particular, emotional expression, internalized visualization, unique visualization, and richness of the imagery emerged. This study implies that the science and art integrated program was closely related to the right hemisphere of the features enabling the subjects to create new ideas, new things, and new reactions. In addition, this program is expected to contribute to activate the brain areas of creativity for gifted students in the science field.

Distance learning makes it possible for educational consumers to study anywhere or anytime. In order to provide effective distance learning, it requires not only educational process and educational results to be closely correlated but also a method for teachers and students to communicate immediately. We devised a dialogue system like a chatting program containing an editor. With this program, students can learn a programming practice by chatting between a teacher and a student. We also incorporated a source code visualization technique based on diff algorithm so that the visualization technique makes it possible for students to recognize the remedies by teachers visually. The result comes by mixing the merits of a dialogue system giving a close interrelationship among users into a programming language education. We expect that the successful result would be tantamount to a face-to-face education.
