The purpose of this study is to provide basic data for prevention of VDT syndrome by confirming VDT syndrome according to the type of computer use. The subjects recruited for the research were 518 students who were in the 4, 5, 6 grades from 5 schools in Seoul. The data were collected during the period from October 8 through October 18, 2004. The results were as follows; 1. The mean value of the VDT syndrome was 1.55 (SD=.52) for the 5th graders. 2. The degrees of VDT syndrome according to the characteristics of the subjects shows higher scores for the 5th and 6th graders, boys, students with more than 4 online friends, students with a low degree of school life satisfaction, and for students with parents who had a negative attitude for their children. 3. The degree of VDT syndrome according to the type of computer use showed higher scores when the students used computers for game more than for study, more than 11 hours in a week, more than 2 hours at one time, not having any rest, in dark places, with the monitor less than 40 an distance from the eyes, sitting with their legs crossed and when the keyboard was in a higher position than their elbows. The internet absorbed group showed higher scores than the unabsorbed group. 4. There was positive correlation between the hours of computer use and VDT syndrome. Also, internet addiction and VDT syndrome had positive correlation. Therefore, each home and society needs to pay consistent attention to correct computer use by their students. Especially, schools will have to educate about computer utilization and VDT syndrome.

In the information society, the ability of learners to use computers to conduct self-directed learning is important. Indeed, the higher the computer's ability to use computers, the more the academic achievement needs to be analyzed. The purpose of this study was to identify longitudinal trajectories of student awareness of ICT literacy and frequency of computer use. We also examined the effects of the longitudinal patterns on academic achievement and college major choice. A non-parametric approach, K-means for longitudinal data(KML) algorithm, was conducted using 9-year longitudinal data from Seoul Education Longitudinal Study (2010-2018). Findings indicated that a pattern presenting a higher awareness of ICT literacy and frequency of computer use showed better academic achievements and was likely to prefer to choose engineering-related majors.

This study aims to examine individual perceptions and lived experiences of the Net generation of student teachers and the previous generation of teachers about their technology use in education. The participants of this study include 106 pre-service teachers and 50 in-service teachers from one teacher education university in Korea. Employing a mixed methodology, we first empirically examined the participants' perceptions toward multiple variables related to technology use in education, namely (a) past ICT experiences in schools, (b) personal computer use, (c) constructivist belief, (d) computer efficacy, (e) attitude toward computer in education, and (f) prospective computer use. In addition, we conducted face-to-face interviews with selected participants for the in-depth investigation of their lived experiences about technology use, beliefs, and attitude. Results indicate that there are significant differences between in-service and pre-service teachers in their prior experiences with technology in schools. However, the pre-service and in-service teachers did not differ significantly in their beliefs, attitude and other technology-related variables, which may indicate the danger of generational determinism in the Net Generation debate. The analysis of interview narratives revealed two major themes about the interplay of one's agency and structural changes in the participants' lived experiences with technology use in education: (a) transition from negative past experiences to opportunities for positive computer use, and (b) attitudes formation and change through apprenticeship experiences and structural influences. In conclusion, this study suggests that the Net Generation debate should move beyond dichotomous or techno-centric thinking. There is a critical need to pay more attention to develop deeper understandings of the fundamental diversity existing within the generation itself. Implications for teacher education are also discussed.

Gaze detection is to find out the position on a monitor screen where a user is looking at, using the image processing and computer vision technology, We developed a computer interface system using the gaze detection technology, This system enables a user to control the computer system without using their hands. So this system will help the handicapped to use a computer and is also useful for the man whose hands are busy doing another job, especially in tasks in factory. For the practical use, command signal like mouse clicking is necessary and we used eye winking to give this command signal to the system.

Computer Graphic design was developed for printed media and its way of expression has been progressed di\ulcornerversely. Especially, the practices of computer graphic are used in textile design enterprise. The use of computer graphics in courses of textile design was produced by various si$$\mu$ations of colors, size and shape in patterns. Then the completed textile was presented as photograph. This paper describes patterns of two dimensions, cloths of three dimensions in use of softwares-TIPS, LUMENCE, FREE STYLE andTOPAS. As mentioned above, we can design fashion with easy by using computer graphics.

This study investigated the extraction algorithm fitting for variables of adolescents' computer use type with the sample from KYPS data (3409 in the second grade of the junior high school; 1704 boys and 1705 girls). The results of the decision tree model revealed that : (1) Gender, computer use time, misdeed friends, parent supervision, other agreement of misdeed, parent study expectation, self-control, teacher attachment, and sibling relation were significant for entertainment type. (2) Gender, cyberclub, computer use time, self-belief, online misdeed were significant for relation type. (3) Study enthusiasm, personal study time, optimistic disposition, study and spare time, cyberclub, self-belief, and other people criticism were significant for information type. These results suggest that adolescents' diverse conditions should be considered for using computer more efficiently.

The main purpose of the study is to identify the key aspects of the use of innovative distance learning technologies in the training of biology students. Currently, there is a modernization, the evolution of the education system from a classical university to a virtual one, from lecture material teaching to computer educational programs, from a book library to a computer one, from multi-volume paper encyclopedias to modern search databases. During studies in higher education, distance learning ensures the delivery of information in an interactive mode through the use of information and communication technologies. The main disadvantage of distance learning is the emotional interaction of the teacher with students. It is necessary to increase the level of methodological developments for independent studies of students. The methodology includes a number of theoretical methods. Based on the results of the study, the main elements of the use of innovative distance learning technologies in the training of biology students were identified.

Modern society is information-oriented society that allow letters in electron, telecommunication, computer, highly Information-Communication and information processing by great development of semi-conductor technologies. All businesses are depending on computer. Also, Great many user according to development who is worth watching eagerly of computer network and utilization of database and technology could collect, search, handle, transmit and store data at the same time using computer. But, while processing and use of information that use computer become convenient, exposure of data became serious relatively. For these reason, Security problem of data that need the secret rose. Accordingly, new encryption methods to use computer for security of data are presented and are developed continuously. Studied about DES, 3DES, RSA, ECC algorithm to select cipher algorithm to use in research hereafter in this treatise.
