Entering upon 21th, the internet which bring the digital era, are changing the paradigm of education and cultivating creative and challenging person, which is the core of competitive power in knowledge-information society, is more emphasized than ever. To meet the needs of the present times, it has been concentrating its effort to improve learning-environment using e-Learning in the field of teaching. E-schoolbooks that were introduced recently by way of showing an example are representative case of this intention. Though many e-learning contents are being developed, the more speedily a society grow, the shorter the life of contents are. Moreover, the contents developed are impossible to use directly for tele-education system, so standard types adjusted for various kind of system are showing up. Among them the leading standard type is SCORM(Sharable Content Object Reference Medel) made in ADL(Advanced Distributed Learning) Corporation. The KERIS' Cyber Home Education System adopted this and is using it. So, in this study, we set the goal at designing and developing an e-learning contents and an experiment-focused mathematics that suit the KERIS' Cyber Home Education System on the basis of SCORM.

This study was performed to evaluate the effect of the e-Learning application on the teaching learning method in Technology-Home Economics of Middle School. For e-Learning of clothing part, diverse teaching programs and contents were reconstructed and provided in cyber-space. Among the uploaded diverse materials including advanced and supplementary materials, students could make a choice which depends on their own levels. Since the results of assignments could be uploaded in cyber-space and easily accessible to all students, the reliablity of estimation was increased and self-directed learning ability was improved. Also, more effective teaching learning activity could be expected through the mutual exchange of opinion between students and teacher, and among students. Besides, counselling and advices on overall aspect of student's life were also possible. The students were generally satisfied to e-Learning instruction. The interest and understanding about clothing part were increased, and the academic attitude and habit were positively changed. Also they responded that e-Learning instruction were very helpful because learning was possible even after school, diverse materials for learning were available, and submitting the results of assignments was very convenient. In conclusion, the application of e-Learning on the teaching learning method was very effective and should be encouraged. The development and supplement of diverse programs and contents will be necessary for more successful e-Learning instructions.

본 논문에서는 현재 웹에서 제공되는 사이버 강의를 수강자가 인터넷을 통해 제공받을 때 사이버 교육컨텐츠들이 대역폭에 미치는 영향을 측정 분석한다. 또한 이더넷(Ethernet)을 통하여 스트리밍 형식의 사이버 강의를 수강할 경우 네트워크에 존재하는 설러 종류의 배경(Background)트래픽에 의하여 대역폭이 점유되므로 한정된 네트워크 환경에서는 강의 수강에 어려움이 있을 것으로 예상된다. 따라서 컨텐츠의 원활한 전달을 위해 FTP(File Transfer Protocol)를 이용하여 배경 트래픽을 발생시켜 이때 측정되는 사이버 강의 트래픽을 분석하여 강의의 전달 특성과 문제점을 파악한다. 마지막으로 사이버 강의를 수강하는 학습자의 위치에 따라 네트워크 환경을 살펴본 후 각각의 환경에서 강의를 수강할 경우를 가정하여 실제 트래픽을 측정 분석함으로써 강의제작에 선행되어야할 바랑직한 조건을 제안한다.

Cyberattacks around the world continue to increase, and their damage extends beyond government facilities and affects civilians. These issues emphasized the importance of developing a system that can identify and detect cyber anomalies early. As above, in order to effectively identify cyber anomalies, several studies have been conducted to learn BGP (Border Gateway Protocol) data through a machine learning model and identify them as anomalies. However, BGP data is unbalanced data in which abnormal data is less than normal data. This causes the model to have a learning biased result, reducing the reliability of the result. In addition, there is a limit in that security personnel cannot recognize the cyber situation as a typical result of machine learning in an actual cyber situation. Therefore, in this paper, we investigate BGP (Border Gateway Protocol) that keeps network records around the world and solve the problem of unbalanced data by using SMOTE. After that, assuming a cyber range situation, an autoencoder classifies cyber anomalies and visualizes the classified data. By learning the pattern of normal data, the performance of classifying abnormal data with 92.4% accuracy was derived, and the auxiliary index also showed 90% performance, ensuring reliability of the results. In addition, it is expected to be able to effectively defend against cyber attacks because it is possible to effectively recognize the situation by visualizing the congested cyber space.

This study examined student's and teachers' perceptions of learning style on internet-based learning. Many research have studied student's learning style both in traditional learning settings and inter-based learning settings. These studies emphasized that student's learning style is one of the important indicators of establishing learning strategies and expecting positive learning outcomes. However, it has been rare to find the comparative analyses between learners and teachers to see how differently they perceive the learning style on internet-based learning. This study analyzed 386 elementary and 627 middle school students and 130 cyber teachers. They filled out the 15 items questionnaire on internet-based learning style. The results showed that the student's and teachers preferred the self-directed internet learning style rather than cooperative and dependent styles. However, the teachers judged the students more self-directed and dependent style preferred than the students self perception. In conclusion, this study suggests the differentiated teaching-learning design and development strategies on internet learning, especially based on subject matter. Also, there should be advanced tutor strategies considering learners' different learning styles. Finally, many research on internet learning styles should be conducted in various learning areas and learner ages and characteristics.

This study proposes basic information to make effective environments for social welfare education, revealing the reasons why students choose the social welfare major at Konyang Cyber University. We conducted qualitative research with 41 students in the social welfare department at Konyang Cyber University. The result of this research is as follows. First, most students chose their major to get a certificate that can benefit them in the near future. Second, they chose their major as a way to achieve renown, and to enhance the quality of their lives. Third, they desired to contribute to society through their social work. Finally, individual experiences and family background were also motives. Based on the research, to improve learning outcomes in social welfare education, the necessary learning strategies are as follows. First, goal-oriented learning is necessary for students who want to get the certificate. A practical curriculum needs to contain both practical skills and professional knowledge applicable to the social work field. Second, education for students who choose the major to gain fame, and to develop their lives, requires generation-integrated education to help them review their lives and find their own meaning in life. Third, education for students who choose the major for a practical social contribution has to contain volunteer training that can lead them to be professional volunteers in society. Fourth, education for students who choose the major based on their personal experiences and their family background needs to deal with case management, which discovers the recipients who need help in society and the students who can achieve visible outcomes after all.
