Recently on IoT environment, there is necessary of protected network, which is only specific user can access it. Applying OAuth protocol on IoT, it can be easier to construct network authentication system, but it is hard to construct protected network authentication system. And there is weakness of OAuth protocol, which is easily attacked by sniffing Token by attacker. So, it is necessary to secondary authentication for OAuth. In ultimate IoT, the fog computing is essential. Fog computing is extension of cloud that enables networking not only in core system but also in edge system and communication node to node. Strength of fog computing is location awareness, support for mobility, and so on. If authentication in fog computing uses this strength, it can be more specialized in Fog Computing. So, in secondary Authentication, using Cyber-Physical-Social System will increase convenience of user than using existing authentication system, such as authentication certificate, id/password and group key, which is inconvenient for user. This study is about authentication based Cyber-Physical-Social System.

Cyber society formed by the development of the Internet is growing rapidly. The Internet is very convenient for our daily life, but it comes with negative aspects including cybercrime and cyberbullying. Recently, there have been incidents that show cyber criminal techniques of adolescents are getting more sophisticated and ferocious. To cope with this crime problem, it is necessary to analyze the causes that affect cyber crime offences among adolescents. There are numerous studies on cybercrime, but less attention has been given to trend analysis. To fill this void, this study examined how the factors that affected the cyber crime offences among adolescents have been changed over time according to transitions in social structure. Implications for future research and policies for adolescents' cyber crime prevention such as time considered response strategies are discussed based on the findings.

This study aims to elucidate the relationship between the characteristics of adult learners and flow in cyber-class along with relationships among flow, stress, and problem-solving ability. The research subjects were 1044 enrolled students at Cyber University located in Seoul through voluntary on-line questionnaire. The analysis is following: The components of flow on cyber-class including enjoyment, engagement, focused attention, and time-distortion show the significant difference upon the characteristics of adult learners such as school grade, age, marital status, and number of registered classes. In addition, the flow on cyber-class has the negative relationship with stress and the positive relationship with problem-solving ability. To improve the level of flow on cyber-class, it is important to develop the new on-line class and class materials with the consideration of characteristics and diverse backgrounds of adult learners. The incorporation of various interactive evaluation can also improve the flow level of adult learners in cyber class. Finally, the learning counselling service might be essential for adult learners to experience flow on cyber-class.

Introduction and application of virtual education has been rapidly increased in these days. A variation of information communication technology has an effect on education in interconnect with network as internet in the world that exceed the limit of time and regional. Computer and network communication technology through the medium of internet make an entrance cyber education as a new education paradigm. It must be affective on learner who have various educational characteristics and requirements. It begins to appear quality, quantity improvements of knowledge and the development of information technology that web based cyber education. This study was conducted to develop the web based education program and to evaluate the effectiveness of learning satisfaction and accomplishment and to compare the cyber lecture system with the traditional lecture system During the second semester of 2001, this study was investigated 317 registered students in a "Food and Culture" class at Kyungwon University. The data were obtained from pre and post-study with self-administered questionnaire. The evaluation and satisfaction score of students who were registered in cyberclass was negative tendency to compare pre with post-test scores, because of insuffciency of computer-aided lecture system. The major problem was inconvenient in checking system for connecting times in cyberclass which was one of evaluation point in final score. Another problem was frequently disconnection during cyber studying and not to concentrate each time in the cyber lecture because of eye fatigue, boring due to less interesting contents than other newly developed web-site. The students was prefer to mix type of the cyber and traditional lecture type class. The result of final score an each class, the score of cyber class (71.36 $\pm$ 22.44) was significantly lower than other groups (mixed type : 76.66 $\pm$ 19.99, traditional type :79.17 $\pm$ 15.72) (p < 0.05). Cyber class was attempted to present a useful and interesting teaching and learning tool which can be applied successfully in a longer term. The result suggest that various teaching and learning strategies should be developed considering the fact that the student learn alone most in time.t in time.

This paper examined its possibility and made its new definition by finding relevant bases in order to make a close inquiry into its Identity and direction at this point when cyber-based gifted education academy is established and operated again by its necessity And 4 models which can be used in special education for the gifted were developed making a link with special education for the gifted by collecting and re-classifying cyber educational methods developed by basic research as priority of the educational method which is considered to be the most urgent issue in practical cyber learning. It is a project-type cooperation education model, an information collection-type research education model, a community-type discussion education model, and a problem focus-type e-PBL education model. To apply developed leaching-learning models to reality, students at gifted education academy in Gyeonggi Cyber Gifted Province were imputed models in different ways respectively for 4 months. As a result of analysis and statistical data of activity level and satisfaction level of students who participated in learning activity, it appeared that high level of satisfaction and active activity level were induced compared to the previous method based on tasks. It is expected that this paper will provide the bases when each cyber-based gifted education academy plans operation plan later on, and it will provide proper methods when cyber guidance teachers plan class activities.

There is a growing interest in psychological counseling and pyschotherapy and many experts are working to help clients more efficiently. Given the many advantages of cyber counseling can be a good alternative to traditional face-to-face counseling. This paper examines the trends of cyber counseling and psychotherapy in South Korea. As a result, when comparing traditional counseling with cyber counseling, cyber counseling had advantages such as high accessibility, convenience, cost reduction effect, and inconvenience in face-to-face counseling. In addition, cyber counseling in South Korea began in the late 1980s, and many studies were conducted for teenagers who are familiar with ICT. Lastly, I briefly researched the current status of cyber counseling and psychotherapy in South Korea. Currently, more active cyber counseling and psychotherapeutic interventions are being carried out using images, AI, and VR. However, because the interdisciplinary approach is somewhat lacking, it is necessary to develop various counseling and psychotherapy programs and verify the effectiveness through the interdisciplinary approach.

Providing female students with competitive advantages in their social activity became one of the important issues of the college education in Korea. Thereupon, for the purpose of more effective and systematic support for the female students, many universities have adopted the cyber mentoring system. However, customers' requirements for such cyber mentoring systems are not reflected at the initial stage, resulting in some inefficient performances. In this study, we propose a desirable cyber mentoring system reflecting female students' requirements by using QFD and conjoint analysis. We expect that the proposed system will help to cultivate high quality female resources in a more effective way.

The new paradigm of education in the cyber space is not limited by time or locations. The students do not need to attend classroom physically and simultaneously. This study tries to probe the relationships among demographic variables and instructional variables with students' satisfaction with the management class in a cyber university. The results demonstrate that demographic variables are not significantly related with students' satisfaction. Rather instructional variables such as personal interactions with professors, job related contents and careful reduction of difficulties countered during the class proceeding are more significantly related with learning satisfaction. The result shows the newly emerged internet based education system requires in-depth cooperation among professors, system engineers, education instrument designers, and students.
