Injection molding machine is the assembly of many kinds of mechanical and fluid power part and electro-electronic control system. From in these, fluid power is a part where becomes the first core of this machine. Fluid power systems of injection molding machine are modelled and analyzed using a commercial program AMESim. The analysis model which is detailed about the parts applied a publishing catalog data. Sub system models which is divided according to functional operation are made and its analysis results shows how design parameters work on operational characteristics like displacement, pressure, flow rates at each node and so on. Total fluid power circuit model is also made and analyzed. The results made by analysis will be used design of fluid power circuit of injection molding machine.

This paper proposes a dynamic formatting method for processing large amounts of document in a device independent manner. And it is very useful for cross-referencing among pages in a single document and for presenting multiple pages simultaneously. The method can be applied usefully to hypertext's application such as establishing a link and a cross-reference among pages in a multiple document. We implemented an electronic publishing system of WYSIWYG type using X window system and Motif graphical user interface.

Video has become an important element of multimedia computing and communication environments, with applications as varied as broadcasting, education, publishing, and military intelligence. The necessity of the efficient methods for multimedia data retrieval is increasing more and more on account of various large scale multimedia applications. According1y, the retrieval and representation of video data becomes one of the main research issues in video database. As for the representation of the video data there have been mainly two approaches: (1) content-based video retrieval, and (2) annotation-based video retrieval This paper designs and implements a video retrieval system for using semantic-based annotation.

The purpose of this study is to investigate the textual and physical bibliography of these books that were printed from Koryo to Chosun Dynasty and written by the Kukyul system. This study is concerned with the Kukyul written in the transformed Chinese characters which representing their sino-Korean sound values only. The Kukyul is the Korean function word inserted to a written Chinese sentence for an easier understanding of the meaning by the Koreans. Until the present, most of these studies on the Kukyul are mainly concerned with the Korean linguistic characters. But this mentions to present the basic bibliographical information in order to presume the written period of the Kukyul system. 2The analysis of each book is made in the respect of: 1) historical aspect of the book 2) physical form and publishing date 3) transcription period of the Kukyul 4) the category of presenting Kukyul 5) historical change of transcribing Kukyul system The results of the study are as follows : First, the Kukyul system was divided into Sokdok and Sundok Kukyul according to the translation and recording format. Second, the Sokdok Kukyul is a kind of writing system for translated Chinese into Korean. Third, the Sundok Kukyul was frequently used Buddhist publications from later Koryo Dynasty to Middle Chosun period. Fourth, through the analysis of physical bibliography for that books, we rearrange the chronological oder of Sokdok Kukyul system as Hwaum-kyung, Hwaum-kyungSo, Kumkwngmyu ngkyung, Kuyeukinwang-kyung, Yukasajiron. Fifth, the characters of Sundok Kukyul systems were gradually decreased from eighty numbers to fifty numbers. This change is caused by the unification trends of sound value in morphological aspect.

In this paper we have developed an image security system based on Internet Web in order to overcome the problem of existing systems that use the dedicated network. The developed system resolves the safety problem of the centralized control model by adapting the distributed control model based on Web, and has the functions of remote control and automatic monitoring for grouped multiple sites on remote Web browser. And the system can operate various computers or operating system because it' s operating software was designed by the concepts of Java Virtual Machine and Virtual Instrument. Also, our system has not need of additional cost for network construction by using Internet and can greatly improve the managemental efficiency of system because the maintenance and publishing of software updates can be performed through Web Server.

As the informal graph was introduced newly in the area of function in middle school mathematics curriculum revised in 2015, ten publishing company became to have a concern on how to represent the graph content uniquely and newly. At this time, it may be meaningful and useful to compare and analyze the content of the graph unit shown on each textbook published by publishing companies. To accomplish this, on fundamentally the basis of diverse prior researches this study tried to select the elements of expression and interpretation of the graph and establish an analytic frameworks of expression and interpretation of the graph respectively. This study executed the frequency analysis and cross analysis by textbook system, textbook, and the number of the graph drawn on a coordinate plane on the representation and interpretation of the graph. As a result, the textbook contains more items on interpretation than the representation of the graph, and students showed a learning effect on the graph unit but showed a neutral response to the impact of learning. This basic and essential paper shed light on developing the practical and more creative textbook which has diversity and characteristic respectively, while adjusting the scope of the elements of the graph's representations and interpretations and providing proper level and quality content.

This study proposes web-based authoring system for the lecturers who published textbooks by inserting external open resource. When lecturer publishes textbooks, the system makes it easier to utilize external resources by providing an open resource pool that the lecturer can search not only his own resources but external resources. In addition, we designed an open resource pool based on Original Contents Tracing Model to check whether the scrapped resource is changed or not in the future. Open Resource Pool allows inserting text, images and videos by searching multimedia, and stores metadata for the follow-up management. We made the system to determine the change of the resource using the metadata stored in the tracking system. Through this research, we confirmed that it is possible to publish textbooks by utilizing a variety of open resources on the web and revise the book by tracing the scrapped resources.

As the improvement of computer performance and the development of IT technology have influence upon publishing industry, the e-Book system, a type of electronic resources, has come out. This is a method to use both texts and 2D image illustrations. Nowadays, there are more and more users who want high quality contents and a variety of contents such as the illustrated fish book using the 3D system. This article adds 3D animation objects to the current e-Book system and designs and realizes the 3D fish simulation system to which e-Book technology is applied so as to improve the comprehension of texts and readability of detailed information and increase readers' immersion as well.
