In recent years, indoor simulated sports have become widely used, and screen baseball system has emerged that can play baseball in indoor space. In this paper, we propose a virtual pitching system that can improve the realism of screen baseball game. This virtual pitching system is characterized in that it uses a transmissive screen in the form of a pitching machine without a pitching hole and installed on the back of the screen. Therefore, unlike existing systems where pitching holes are formed on the screen, it enhances the immersion feeling of displayed images. Also, in this pitching system, the synchronization algorithm between the pitching machine and the virtual pitcher is used to form a sense of unity between the virtual pitcher and the ball according to various types of virtual pitchers, thereby enhancing the reality of baseball games.

In this paper, we propose a web inspection system (WIS) for real-time detection of paper defects which can cause critical fractures during papermaking process. Our system incorporates high speed line-scan camera, lighting system, and detection algorithm to provide robust and precise detection of paper defects in real-time. Since edge defects are very crucial to the paper fractures, our system focuses on the edge region of the paper instead of inspecting the whole paper area. In our algorithm, image projection and sub-pixel operation are utilized to detect the edge defects precisely and connected component labeling and shape analysis techniques are adopted to extract various kinds of the region defects. Experimental results revealed that our web inspection system is very efficient for detecting paper defects during papermaking processes.

In current computer education, we have inclined to emphasize information literacy for k-12 students. On the other hand, in spite that teachers are core variable in school education system, we have neglected teacher's education of information and communication technology. In addition, we haven't made a effort to expand preservice teacher's ability to utilize information and communication technology in the teacher's college and the college of education. With these recognitions, we made a diagnosis of problems by analysis of current condition of curriculum of the teacher's college and the college of education and explored the vision of ICT utilization education in k-12 computer education in this study. In addition, we suggested educational objectives and contents based on national requiring standards for ICT in teacher preparation, required ICT capability of preservice teachers for kind of teacher's task and the direction of computer education.

Public and private schools have close relationship with education-related organizations and they have exchanged formal documents to communicate each other. Introducing the XML/EDI used in electronic-commerce to the education web will make a great benefit for decreasing affairs in educational administration. In this paper, we implement a document management system using XML/EDI. This system makes it possible to treat documents which are not supported in current education-information-exchange system and can be added to the current system without any additional modification. We analyze the documents used in the current system and implement new types of tags suitable for education web. In addition, we difine new documents and DTD using only XML without any application software. This will have effects on reducing teacher's administrative work and enable teachers to concentrate on their teaching.

This article identifies the problems and substantiates the directions for the development of distance learning technologies in the training of personnel. An example of using digital media to create a remote access laboratory is given. The article is devoted to the definition of the main aspects of the organization of distance education. Rapid digitization, economic, political and social changes taking place in Ukraine necessitate the reform of the education system. First of all, it concerns meeting the educational needs of citizens throughout their lives, providing access to educational and professional training for all who have the necessary abilities and adequate training. The most effective solution to the above-mentioned problems is facilitated by distance learning. The article analyzes the essence and methods of distance learning organization, reveals the features of the use of electronic platforms for the organization of this form of education in different countries of the world. The positive characteristics of distance learning are identified, namely: extraterritoriality; savings on transport costs; the interest of modern youth in the use of information tools in everyday life; increase in the number of students; simplicity and accessibility of training; convenient consultation system; democratic relations between the student and the teacher; convenience for organizations in training their employees without interrupting their regular work; low level of payment for distance education compared to traditional education; individual learning pace; new teacher status. Among the negative features of online education, the author refers to the following problems: authentication of users during knowledge verification, calculation of the teacher's methodological load and copyright of educational materials; the high labor intensity of developing high-quality educational content and the high cost of distance learning equipment; the need to provide users with a personal computer and access to the Internet; the need to find and use effective motivation mechanisms for education seekers.

Generally, teaching in computer Labs is more difficult than teaching in a normal class for teachers to give students systematic learning. One of the reasons is that the students who participate in the class tend to use the programs that are not related to the practice included in the curriculum. Therefore, the students cannot focus on the subjects that they should do. To solve this problem, there are many kinds of systems that can control the students' computers. However, they cannot help teachers to manage the students and computers due to the inconvenience of usage and the lack of functions. In this study, we analyzed the problems in the computer-practice classwork and designed a new system to support that the students can participate in the computer classes with more attention. In addition, it is offered that the computer teachers can manage the classes and the students more efficiently with this new system. For these purposes, the effects mentioned were approved before in the real lab situations. Experimental results showed that the proposed system can improve the rate of the students attention, leading them to get better grades on the achievement test.
