Developing a new texture path tool is crucial in 3D industries to automatically manage and set up texture paths for characters and environment modelings. For a better study, I compare the problems, methods and functions of the new tool(SongRepath tool) with other commonly used tools such as File Path Editor, Genie, He Texture Path. Next, I analyze the top down method system for these commonly used tools, and create a new bottom-up algorithm for a better use and efficiency. Finally, analyzing and comparing SongRepath tool with other tools in terms of operation in convenience, steps for results, checking number of Texture files, checking the numbers of new paths, checking the numbers of files not found, checking the numbers of path not changed, errors or problems, and availability of cancelation while proceeding the result. As a result, this study shows that SongRepath tool has less errors and saves more time on the processing works.

This study suggests efficient production of game with spine tool that is 2D game tool. For this, the researcher studies process and efficiency of game development by focusing on production of a game "Shooting Monster" Version 1 in service of Google Store at present. Production tools in a contents field are sharply changed. In addition, these tools are automatized into new version and efficient product. These tools help manufacturers in increasing quality of contents and time efficiency. Therefore, the researcher examines understanding of development process of existing 2D game and problems in development stage of graphic character, and analyzes production stage of character animation using spine tool, so suggests effective process of production in terms of production. The purpose of this study is to suggest the direction about graphic efficiency of tool by accessing production process to train working-level talented people in 2D mobile game field.

In the present study, the middle school students' perception on the environment course was surveyed before and after three different lessons. It was found that most students were taking environment related issues mainly from mass media including internet and broadcasting. The young students were satisfied at practical experiments, but at the same time a few old fashioned experimental programs would not be preferred. Utilization of multimedia such as audio-visual tools was one of the effective tools for the environment class, because it could help to understand even the profound principles of the chemical and physical processes. However, some students did not concentrate on the display, causing frequent disturbance of the class. Since the school for this investigation did not choose the environment as a selective course, practical tools and materials for the experiment should not be sufficient, and thereby a further detailed work must be followed with the students who are taking environment lessons.

Developing tailor made Multimedia courseware ensuring effective implementation of instruction strategies is a challenge that manifests in myriad problems of software design and coding. In this paper an attempt has been made to analyse and identify coding and implementation problems, in the backdrop of using two different multimedia software development tools i.e. Visual Basic and Toolbook, which underpin the development and effectiveness of use of multimedia courseware. Solutions to such problems have been discussed in context of Tool book. The examples presented in this paper are based on the experience of designing and implementation of two large scale professional quality Multimedia courseware development projects.

Web caching server is one of the important components of any web site, as it makes the access of users to web content much faster while balancing the network and server load. There are many caching approaches proposed in order to solve this problem. Classically, we know several caching algorithms like FIFO, LRU, LRU-min and etc. Most of them have their advantages and disadvantages based on specific context. The purpose of this paper is to introduce the new concept of caching objects along with their related content and test the performance of the proposed caching method using CPN Tools simulator program. It is generally known that the use of Colored Petri Nets(CPNs) for modeling the simulation of new idea is one of the popular methods of system evaluation throughout software development projects. Moreover it could be very handy in describing the overall logic of the system. The CPN Tools is one of the most robust simulator programs which supports all necessary tools and functions to build and run the simulation model for CPN. Therefore in this paper, we will use CPN Tools software in order to build a simulator for our innovative caching approach named as web caching with related content. Then we will analyze the results derived from the simulation of our model and will make corresponding conclusions.

A 3D stereoscopic image is generated by interdigitating every scene with video editing tools that are rendered by two cameras' views in 3D modeling tools, like Autodesk MAX(R) and Autodesk MAYA(R). However, the depth of object from a static scene and the continuous stereo effect in the view of transformation, are not represented in a natural method. This is because after choosing the settings of arbitrary angle of convergence and the distance between the modeling and those two cameras, the user needs to render the view from both cameras. So, the user needs a process of controlling the camera's interval and rendering repetitively, which takes too much time. Therefore, in this paper, we will propose the 3D stereoscopic image editing system for solving such problems as well as exposing the system's inherent limitations. We can generate the view of two cameras and can confirm the stereo effect in real-time on 3D modeling tools. Then, we can intuitively determine immersion of 3D stereoscopic image in real-time, by using the 3D stereoscopic image preview function.

ODBC는 동적인 클라이언트/서버 환경에서 특히 효과적이다. ODBC는 멀티미디어데이터를 처리할 수 있는 특징 때문에 멀티미디어 서버로 지원할 수 있다. 본 논문에서는 관계형 DBMS 위한 ODBC 드라이버를 개발하였다. 이 드라이버는 클라이언트 모듈과 서버 모듈로 구성되었다. 클라이언트 모듈은 SRM 이라 하고 서버모듈은 CSM 이라 하였다. 이들 두 모듈은 NSM 이라 부르는 네트워크 모듈을 통해서 연결된다. 본 논문에서 개발한ODBC 드라이버 테스트는 기능과 정보처리 상호 운용 가능성을 테스트하였으며, 그 결과 드라이버는 클라이언트 DBMS 툴로서 성공적이었고, 멀티미디어 데이터 처리가 가능할 뿐만 아니라 DBMS 툴을 포함하는 클라이언트 응용 프로그래밍 인터페이스를 지원할 수 있는 것으로 나타났다.

With the rapid evolution of communication technology, it became possible to overcome the spatial and temporal limitations faced by humans to some extent. Furthermore, the quality of personal life was revolutionized with the emergence of the personal communication device commonly known as the smart phone. In terms of defense networks, however, due to restrictions from the military and security perspectives, the use of smart phones has been prohibited and controlled in the army; thus, they are not being used for any defense strategy purposes as yet. Despite the current consideration of smart phones for military communication, due to the difficulties of network configuration and the high cost of the necessary communication devices, the main tools of communication between soldiers are limited to the use of flag, voice or hand signals, which are all very primitive. Although these primitive tools can be very effective in certain cases, they cannot overcome temporal and spatial limitations. Likewise, depending on the level of the communication skills of each individual, communication efficiency can vary significantly. As the term of military service continues to be shortened, however, types of communication of varying efficiency depending on the levels of skills of each individual newly added to the military is not desirable at all. To address this problem, it is essential to prepare an intuitive network configuration that facilitates use by soldiers in a short period of time by easily configuring the strategy network at a low cost while maintaining its security. Therefore, in this article, the author proposes a Zigbee-based local strategic network by using Opnet and performs a simulation accordingly.
