  • The purpose of the research was to investigate the characteristics and related factors of cyber dating violence. The subjects were 548 adolescents in high schools. The gathered information was analyzed by frequency, percent, 1-test, ANOVA, and Correlation by using SPSS 10.0 program. The results were as follows: (1) $65.3{\%}$ of the answerers experienced cyber dating, and $44.5{\%}$ of the students have experienced cyber dating violence. (2) $40.3{\%}$ of the students were damaged by psychological violence, and $21.1{\%}$ of the students have caused psychological violence. (3) $41.9{\%}$ of the damaged students and $18{\%}$ of the perpetrating students were included in the total answerers, but among 244 experienced students, $94.3{\%}$ were damaged students and $40.6{\%}$ perpetrated sexual violence, so it is concluded that experienced students experience sexual violence. (4) Looking over the social demography factors and cyber dating violence, boys rather than girls, and vocational school students rather than academic school students have more cyber violence experiences. (5) The relationship between psychological and sexual violence has a significant relationship with all cyber violence experiences.

  • The purpose of this study was to evaluate the effects and define the educational strategies of the cyber education offered to students for Bachelor of Science degree program(RN-BSN). The participants in this study were 67 students in two courses, Growth and Development, and Nursing Process. The main components of the cyber classes were the electronic board and on-line discussion board. The study was conducted from March 4, 2001 to July 23, 2001 at Y University in Seoul, Korea. To examine the effects of the cyber education, learning motivation, and learning satisfaction were measured by questionnaires to the students before the initial class and after completing the class. Learning achievement was measured by the grades for each course. The data were analyzed using frequencies, t-test, and paired t-test. The specific results of the course evaluation were compared and analysis was done to examine differences between traditional classroom teaching and cyber teaching. The study results are as follows: 1. There were no significant differences on total scores for learning motivation between pre-cyber education and post-cyber education. However, there were significant decreases in the post test compared to the pre test for the items, ' I'd like to get as high a score as possible compared to other students (t=-2.20, p=.03)' and ' I'm sure to acquire good grades(t=-5.22, p=.00) '. 2. The average score for learning satisfaction using cyber education was high at 3.52. 3. To define learning achievement using cyber education, grades for students taking cyber classes this year were compared to student grades for a class using traditional lassroom teaching last year. The score was significantly higher for classroom students in the 'Growth and Development' course (t=-3.5, p<.001), and the score was significantly higher for the cyber education students in the 'Nursing Process' course (t=4.3, p<.000). 4. The average of post scores on computer competency was significantly higher on six items, general knowledge about computers, data management and data research, ability to communicate using computer, and internet surfing. On the basis of the above findings, this study suggests that cyber education in nursing courses is effective and readily available. However, it is recommended that consideration be given to characteristics of the course when developing cyber education programs for nursing courses.

  • In these days, the world is getting connected to the internet like a sophisticated net, such an environment gives a suitable environment for cyber attackers, so-called cyber-terrorists. As a result, a number of cyber attacks has significantly increased and researches to find cyber attack traffics in the field of network monitoring has also been proceeding. But cyber attack traffics have been appearing in new forms in every attack making it harder to monitor. This paper suggests a method of tracking down cyber attack traffic sources by defining relational information flow of traffic data from highest cascaded and grouped relational flow. The result of applying this cyber attack source tracking method to real cyber attack traffic, was found to be reliable with quality results.

  • The Necessity of Cyber University. Within the rapidly changing environment of global economics, the environment of higher education in the universities, also, has been, encountering various changes. Popularization on higher education related to 1lifetime education system, putting emphasis on the productivity of education services and the acquisition of competitiveness through the market of open education, the breakdown of the ivory tower and the Multiversitization of universities, importance of obtaining information in the universities, and cooperation between domestic and oversea universities, industry and educational system must be acquired. Therefore, in order to adequately cope wi th these kinds of rapid changes in the education environment, operating Cyber University by utilizing various information technologies and its fixations such as Internet, E-mail, CD-ROMs, Interact ive Video Networks (Video Conferencing, Video on Demand), TV, Cable etc., which has no time or location limitation, is needed. Using informal ion and telecommunication technologies, especially the Internet is expected to Or ing about many changes in the social, economics and educational area. Among the many changes scholars have predicted, the development and fixations of Distant Learning or Cyber University was the most dominant factor. In the case of U. S. A., Cyber University has already been established and in under operation by the Federate Governments of 13 states. Any other universities (around 500 universities has been opened until1 now), with the help of the government and private citizens have been able to partly operate the Cyber University and is planning on enlarging step-by-step in the future. It could be seen not only as U. S. A. trying to elevate its higher education through their leading information technologies, but also could be seen as their objective in putting efforts on subordinating the culture of the education worldwide. UTRA University in U. S. A., for example, is already exporting its class lectures to China, and Indonesia regions. Influenced by the Cyber University current in the U.S., the Universities in Korea is willing .to arrange various forms of Cyber Universities. In line with this, at JUNAM National University, internet based Cyber University, which has set about its work on July of 1997, is in the state of operating about 100 Cyber Universities. Also, in the case of Hanam University, the Distant Learning classes are at its final stage of being established; this is a link in the rapid speed project of setting an example by the Korean Government. In addition, the department of education has selected 5 universities, including Seoul Cyber Design University for experimentation and is in the stage of strategic operation. Over 100 universities in Korea are speeding up its preparation for operating Cyber University. This form of Distant Learning goes beyond the walls of universities and is in the trend of being diffused in business areas or in various training programs of financial organizations and more. Here, in the hope that this material would some what be of help to other Universities which are preparing for Cyber University, I would 1ike to introduce some general concepts of the components forming Cyber University and Open Education System which has been established by JUNAM University. System of Cyber University could be seen as a general solution offered by tile computer technologies for the management on the students, Lectures On Demand, real hour based and satellite classes, media product ion lab for the production of the multimedia Contents, electronic library, the Groupware enabling exchange of information between students and professors. Arranging general concepts of components in the aspect of Cyber University and Open Education, it would be expressed in the form of the establishment of Cyber University and the service of Open Education as can be seen in the diagram below.

  • Cyber education has been predicted that it would become the primary education system of 21st century as a way of education focusing on consumers, with the aspect that it seems to be able to satisfy the demand about re-education and lifelong education as the acceleration of fast knowledge accumulation throughout every field of society in the digital era. However, cyber education system has a lot of problems which are for that it lacks of human resources for effective interaction, and it can be disadvantageous to certain type of students with a class environment concentrated on reading and writing and with foundation on computer technology. Therefore, in this thesis, We intended to analyze factors influencing satisfaction of people studying in a situation that cyber education has been required to be a mainstream system of education in the midst of trend of changing paradigm of college education recently, and to suggest some possible solutions for cyber education at university.

  • Participants in real-time online sessions, be it (business) meetings, virtual school lessons, or social live streams, all engage in cyber social interactions. Unlike parasocial interactions, cyber social interactions are characterized by reciprocity and temporal proximity. In contrast to social interactions, they lack spatial proximity and bodily contact. This is a fairly new concept in information science that rose from technological advances and unprecedented circumstances (e.g., the rise of digital economy and knowledge workers being able to work remotely or, more recently, global lockdowns and contact restrictions). As a result, the past ways of working and socializing were transformed by making them, in some cases predominantly, virtual. Regarding the example of social live streaming we exhibit the importance of cyber social interactions for information behavior research. This conceptual article is a plea for information science to engage more in human-human online relations and interactions.

  • This paper addresses the control problem of cyber-physical systems under controller attack. A novel discontinuous Lyapunov functionals are employed to fully utilize sampled-data pattern which characteristic is commonly appeared in cyber-physical systems. By considering the limited resource of networks, cyber-attacks on the controller are considered randomly occurring and are described as an attack function which is nonlinear but assumed to be satisfying Lipschitz condition. Novel criteria for designing controller with robustness for cyber-attacks are developed in terms of linear matrix inequality (LMI). Finally, a numerical example is given to prove the usefulness of the proposed method.
