Smart phone games market is getting bigger. In this circumstance, the Experience game focusing user's activity is popular among the smart phone games because the user can be easily absorbed into the game and felt more sense of unity with the game. there are several studies about game storytelling which focus on story visualization or effective methods of game design, but the study of game storytelling connected with user's activity is not entirely satisfactory. Therefore, in this paper, we introduce a system for user's activity visualization of the experience game for smart phone. To achieve this, firstly, we show the model which is about the overall configuration of experience game for smart phone. secondly, the detail configurations of the overall game model is introduced. lastly, standing on the model, we introduce a simulation model and a developed program.

Software visualization can assist developers to understand a software system and change its code. The recent development of bottom-up visualization tools demonstrates the advantages by revealing the code that is directly related to a software evolution task. However, the information provided by these tools is limited to the code already investigated by the developers in that task session. To broaden the scope and provide the code information that developers should explore, we propose to present the latest revision of a software system via a class diagram. When a developer clicks on a button, the proposed tool reveals the code changes committed to a configuration management system, and facilitates the understanding of code changes. We also conduct case studies illustrating the advantages of the proposed tool.

Due to improvements in the capabilities of commercial game engines, there are increasing instances of applying game engines to scientific visualization applications. This study describes a case of creating a virtual reality application that visualizes medical volume data based on the Unity3D game engine. When using a game engine, there is an advantage that various functions required for an application are basically provided, such as depth sorting of translucent objects or virtual reality hardware support. On the other hand, there is a restriction that the structure of the application program should be modified to suit the characteristics of the game engine. This paper describes a method for visualizing medical volume data using the structure of a game engine. As a result, we were able to create a virtual reality scene that consisted of surface data and medical volume data fragments together. And we confirmed the possibility of game engine as a future medical simulation production tool.

The earlier KANSEI evaluation had to choose not to overlap the opposite meaning of the words, had to choose that some figures are shown step by step and had to choose be prepared things in advance. However, The Study shows a method which visualizes the imprecise evaluations of human without choosing evaluation items which are not prepared figures. The program is used the way which is entered by hand-drawing that the subjects use the way to enter their subjective feelings about the evaluations presented by using the mouse or the graphics tablet. It is possible to express imprecise things about evaluations and the method of drawing is free. The program provides that we can express our thinking by drawing and there are a few limits and the prescribed standard. The area ratio of each circle is expressed as a pie chart and the area of circle what is drawn which is counted automatically at the same time. These things are possible not only to modify a transparency, a thickness of a line, a color and the area of circle what is drawn, but also to adjust the area of circle. The conceptual model is visualized that expresses something by hand-drawing such as a circle. The conceptual model has wide range of applications such as a personnel evaluation, a suffering evaluation and product evaluation. The program currently has been testing the effective of the program's possibilities which is used with the personnel appraisal tool of the nurses themselves who work in nurse support department where the St. Marianna University School of Medicine Hospital is. And also the program is proceeding with development to visualize the conceptual model by dynamic interfaces effectively and the program is applied such as KJ method and a program is used to express the kind of the patient's pain and its level.

In this paper, we propose a client server based distributed/parallel system to effectively visualize huge geographic data. The system consists of a web-based client GUI program and a distributed/parallel server program which runs on multiple PC clusters. To make the client program run on mobile devices as well as PCs, the graphical user interface has been designed by using JOGL, the java-based OpenGL graphics library, and sending the information about current available memory space and maximum display resolution the server can minimize the amount of tasks. PC clusters used to play the role of the server access requested geographic data from distributed disks, and properly re-sample them, then send the results back to the client. To minimize the latency happened in repeatedly access the distributed stored geography data, cache data structures have been maintained in both every nodes of the server and the client.

In Jana 2, to enforce a suity policy of a program, programmer writes permission sets required by the code at the policy file, sets Security Manager on system and executes the program. Then Security Manager checks by stack inspection whether an access request to resource should be granted or denied whenever code tries to access critical resource. In this paper, we develop a visualization tool which helps programmers enforce security policy effectively into programs. This system is based on the static permission check analysis which analyzes permission checks which must succeed or fail at each method. Based on this analysis information, programmer can examine visually how permission checks and their stack inspection are performed. By modifying program or policy file if necessary and examining analysis information repeatedly, programmer can enforce security policy correctly.

Environments surrounding production sites have changed greatly in recent years. Accommodating environmental changes calls for the design and development of information systems that center on production lines. There is a need for a training program that teaches learners to understand the particulars of an operation and apply that knowledge to an information system. In this research, we used material requirements planning (MRP) as the subject for which basic skills are to be taught and developed an MRP exercise-based training program. The program is designed for 13 lectures of 90 minutes each, and it consists of MRP exercises, modeling methods to represent them, the use of a programming language for system development, and finally, evaluation of the exercises. Lecture materials are described in 505 lecture slides using Microsoft PowerPoint to allow visualization of topics through graphs and models. The developed training program was then delivered to 86 college students, and its results were measured through quizzes to verify educational effectiveness.

RNA pseudoknots are not only important structural elements for forming the tertiary structure, but also responsible for several functions of RNA molecules such as frameshifting, read-through, and the initiation of translation. There exists no automatic method for drawing RNA pseudoknot structures, and thus representing RNA pseudoknots currently relies on significant amount of manual work. In this talk, I will introduce the first algorithm for automatically generating a drawing of RNA pseudoknot structures. Two basic criteria were adopted when designing the algorithm: (1) Overlapping of structural elements should be minimized to increase the readability of the drawing, and (2) The whole RNA structure as well as the pseudoknots themselves should be recognized quickly and clearly. The algorithm has been implemented in a JAVA program, which can be executed on any computing systems. Experimental results show that this program generates a clear and compact drawing of RNA pseudoknots and allows a biologist to gain insights into RNA pseudoknot structures. The program can also be used as useful aids in designing biochemical experiments to elucidate more precise mechanism of RNA functions associated with pseudoknots.

With existing illumination rendering system being used in domestic, internationally developed common programs are taking over the market more than 90%. However, since the programs are established with DB designed to be most suitable for their own products, accuracy in analysis and visualized image are hardly reliable. This raises the necessities of establishing DB for domestic developed products. A method of establishing artificial luminair DB, which was studied on DB establishment in consideration of optical characteristics of domestic products with using RADIANCE program was presented in this study, and it is considered as the program of simulating light movement most accurately among all rendering programs developed so far.
