A detection method of high precision digital line within image is proposed in this paper. If we set the size of image to $N{\times}N$, in fact it is difficult to use the resulting values that the amount of computation is $O(N^4)$. Multiple algorithms are examined to reduced the amount of computation to $O(N^3)$, while suppressing the degradation of precision. How to detect line from the image processing, after stretching treatment of line segments extracted by Hough transform in the local area of an image is a great way to be able to detect several long or short line at high speed, but this method is slightly less precision in the detection of tilted line segments. In this paper, a line detection method improving the precision detection of tilted line segment is applied to the local area, thereby this method does not reduce the processing speed, while it is high precision method for detecting line segments. The experimental results confirm that the proposed method can detect a high precision line in a shorter period of time, compared with the existing methods.

Countries around the world are strengthening informatics education to cope with the development of technology that leads to rapid social change. The last step in the capacity to foster through formal education is high school education. The purpose of this study is to examine the competence and level of informatics curriculum for high school students who aim to enter university in terms of testing tools. In order to carry out the research, we analyzed informatics education related test tools for high school students such as Japan, Germany, and USA. The results of the analysis are as follows: First, both the essay type and the short answer type question are included in the test tool as well as the multiple choice question type. Second, we use the real world model as an item and ask whether we can use computing power for practical problem solving ability. Third, the items directly related to the university education are reflected in the items. This study suggests that it has helped to elucidate the features and discussions of the test tool and establish the development direction of the test tool for informatics education.

Typical examples as unrecycled materials in Korea were Zinc from the electric arc furnace dust (EAF Dust), and Moiybdenium and Vanadium from the desulfurizing spent catalyst of petrochemical industries. In the otherwise, though recovery of valuable metals from the waste electronic scrap such as printed circuit boards (PCBs) and platinum group metals (PGM) from the waste automobile catalyst have been interesting issues, it is difficult to collect the exact informations or statistics on their material flow system. In this article, The current domestic research trends for unrecycled or less recycled materials have been reviewed, and material flow and recycling technologies on the desulfurizing spent catalyst were surveyed.

A new method for measuring the performance of a micro-thruster is suggested in this paper. A few thrust stands have been developed for measuring micro-level thrusts. This paper describes a different measurement method that can minimize the calibration involved in the measurements, while providing the capability of directly measuring the produced minimum impulse bit directly. The underlying theory and the theoretical background for the measurement mechanism are described here. The theory and method is verified using a computer simulation, and the result is given in this paper. The theory has also been tested on an actual hardware. Although this hardware is a prototype, developed for proof-of-concept analysis, satisfactory results have been obtained.

The purpose of the research was to investigate the organizational integration process of the university library, computer center and other informa ion related operations. The research process follows : first, the literature review of the organizational integration of the information related operations. second, analysis of the organizational integration in Korea. third, the organizational integration of information related operation in US and Japan, then the case analysis of information related organizational integrations in Korea. This process lead us to point out few problems and pitfalls that could occur in the integration procedure. The total integration procedure has turned out to be the most effective in the University environment. And for the management of fully integrated organization. Vice-President and Chief Information Officer, - who is reponsible to suggest vision, leadership and ability to cope with the complex nature of the future information society - was strongly suggested.

This study aims at an objective analysis of the EBS lecture program for the national scholastic achievement examination (NSAE) that started from April 1, 2004. To this end, it obtained and analyzed related data which are archived in the EBS NSAE lecture system under the assistance from EBS. More specifically, it analyzed the practices of lecturer placement and student members. Also, the practices of use of lectures were analyzed by years, and the economical value from the use of the EBS NSAE lecture program was estimated through the comparison with the level of tuitions for private online institutes. In addition, this study diagnosed the properness in counselor placement through an analysis of the use of the web forum, and analyzed the practices of the nonsul (essay-type examination) program in order to identify the coping strategies of EBS with regard to the introduction of a new system for 2008 university entrance system. As a result of the analysis, this study presents various ways to improve the EBS NSAE lecture program.

Web based instruction (WBI) has been widely used thesedays because the web has various advantages for instruction. However, most of current WBI systems do not support various requirements from students. It is because of the lack of research for structural instruction method. This paper presents a new method of WBI and designs an instruction model to support various requirements from students by implementing dynamic WBI system using JSP to solve current WBI problems. The developed WBI system uses multimedia based instructions. The implemented system focused on the practical instruction by providing the functions of listening, homework, and test on web site. For the similar effects as in the classroom, it supports functions of electronic white board and multimedia data which is consisted of high-quality sound and video data with high degree of compression. Furthermore, the system supports that instructors can design a test using three kinds of basic forms, a multiple-choice test, brief-answer test, essay test, and evaluate the tests easily. It also supports easy management for homework, lecture registration, and many school affairs.
